The PSS Shaft Seal is the number one selling marine mechanical seal
worldwide and is installed as standard equipment by many of the worlds most
reputable boat builders / yards. The PSS Shaft Seal is also recognized as
the premiere retrofit (aftermarket) seal on the world market. Certified by
Bureau Veritas, ABS & Rina: Boat builders / yards recognize the advantages
and value of installing the PSS as it eliminates the maintenance, constant
adjustment & cost associated with traditional packing type glands. Aside
from these benefits, the PSS Shaft Seal helps to eliminate water in the
bilge (100% water tight) & wear to the propeller shaft. The PSS Shaft Seal
can be easily retrofitted and is available for shafts ranging from 3/4"
(20mm) to 6" (150mm).
The PSS Shaft Seal is a mechanical face seal that is created between
the flat surfaces of the rotating stainless steel rotor and the stationary
carbon flange. The stationary carbon flange is attached to the vessels stern tube with hose clamps and the carbon flange is attached to the front side of the bellows with hose clamps. The stainless steel rotor is fit on the shaft
in front of the carbon flange. The stainless steel rotor is used to compress the bellows before the collar is secured to the shaft with set-screws. This
compression (pre-load) maintains contact between the faces and allows the
PSS to compensate for the thrust from the propeller. The carbon flange is
bored larger than the shaft diameter allowing it to "float" around the shaft and thus compensate for most misalignment and vibration problems. The
stainless steel collar is sealed to the shaft by two o-rings that are
recessed into the bore of the collar. These o-rings rotate with the shaft
and stainless steel rotor and do not experience wear during operation.
**As with any rubber hose below waterline, the PSS bellows must be inspected on a regular basis for any sign of wear, aging or chemical deterioration.
PYI suggests as preventative maintenance that the PSS bellow be replaced in
six year intervals. During bellows replacement it is recommended the o-rings & set screws in the stainless steel rotor also be replaced."
Bellows may need to be more frequently inspected in an environment where
non-sealed batteries emit sulfuric acid. Sulfuric acid vapor will accelerate rubber deterioration, as will an ozonater.
The Maintenance Kit includes the items you need to properly maintain your
PSS Shaft Seal. Included in the kit is one (1) PSS bellow, two (2) O-rings,
five (5) set screws, four (4) new hose clamps and an allen key.

A Groundbreaking Classic on Young Child Development
Format: Paperback
This first volume of John Bowlby's trilogy on Attachment and Loss expands and builds upon an article he published in 1958 in the International Journal of Psycho-Analysis titled "The Nature of the Child's Tie to His Mother", which is perhaps a more telling title than that of the book itself. Attachment, as a technical term in behavioural biology, is first used in describing instinctive mother-following behaviours of young mammals and birds (first observed and reported in delightful accounts by the Austrian ethologist Konrad Lorenz in the 1930's).
By comparing data collected during and after the Second World War by childcare workers and researchers in U.K. and North America, Bowlby found a striking common pattern of distressed behaviours among young children between the ages of one and three when separated from mother for an extended period: first in Protest, then Despair and finally Detachment - a psychopathological state when a child becomes socially uninitiated and withdrawn, even to his returning mother. Bowlby then postulates that physical proximity to a mother-figure is essential to a child's development of cognitive capacities, especially during a sensitive period around six months to two years after birth. Attachment behaviours, like those of young mammals and birds, are present in the human baby too. This has since led to a blossoming of research activities in development psychology and psychoanalysis, as well as neurophysiology recently, which supplies much fresh evidence about the young brain and its phenomenal maturing in the first two years. Attachment theory has since contributed significantly to understanding of our own selves, informed the age-old philosophical debate on nature or nurture, and brought our attention to fundamental issues in child-rearing such as sensitive periods of development, the difference between attachment (conducive to security) and dependence (symptomatic of insecurity), the distinction between anxiety from separation and fear of the unfamiliar, etc.
This new edition is a timely reprint of a classic account of attachment theory as formulated by the originator. While primarily an academic work, with a few chapters deemed more for an academic jury (about Freud and instinctive behaviours, etc.), it is mostly very readable, and certainly captivating to those with access to young babies, of whose behaviours are given an enlightening perspective. This volume focuses on attachment, with subsequent volumes on its loss in temporary and permanent terms respectively.

Couples Therapy for Domestic Violence
Format: Hardcover
Very helpful for students, clinicians, and researchers. Great information on understanding domestic violence from a systemic perspective. Excellent outline and explanation of the treatment model and how to implement it with couples and in group formats. This is the only model that offers clinicians like me a clear map to comprehensive treatment services for couples/partners presenting with intimate partner violence / domestic violence. I just purchased 2 more copies for staff interested in implementing the model. A criminal justice professional read my copy and stated: "This is treatment. This is what we need, especially for couples looking at reconciliation."

Smaller than expected
Format: Hardcover
For a book this costly, I expected it to be thicker than volume. That said, there are some great ideas in here and I will probably edit this review when I have finished reading!
