Abstract: 2-776                                             Patent SLIDING DOOR LOCK     Abstract of the Disclosure A lock or latch for a sliding or rolling type door includes front and rear housing members that clamp-ingly engage opposite sides of a door panel adjacent an opening that is formed through the door panel.  Aligned cavities are formed in the front and rear housing members that cooperate with the door panel opening to define a compartment within which a latch bolt member is housed for forward and rearward movement.  The latch bolt member has a rearwardly extending formation that projects through a hole formed in the rear housing member for selectively engaging structure located behind the door to releasably latch the door in its closed position.  An operating mechanism connects with the latch bolt member and includes components that extend forwardly and rearwardly through aligned openings formed through the front and rear housing members to provide means 1) for moving the latch bolt mem-ber forwardly and rearwardly relative to the housing mem-bers between unlatched and latched positions, and 2) for releasably retaining the latch bolt member its unlatched and latched positions.  The operating mechanism preferably includes a forwardly facing key operated lock cylinder that is housed in a forwardly facing push button, and a foldable handle that faces rearwardly.  The push button and the key cylinder are accessible from the front side of the lock for operating the latch bolt member.  The folda-ble handle is accessible from the rear side of the lock for operating the latch bolt member.  Improvements reside in the provision of a sleeve formation that surrounds the push button, and in the provision of weatherproofing seals between components that move relative to the push button.

Inventor: LESAGE JACQUES
IPC: A62B23/02
Filed: 1990-07-05
Abstract: A chemical cartridge (1) for protective respiratory mask (2) comprising separate active filter section and universal filter section. The active filter section is formed of an absorbent medium impregnated with a reagent capable to capture and derive a target toxic pollutant having a chemically active function into an inert, non-volatile and non-toxic matter as air is inhaled. When air is inhaled by the user as indicated by the arrow (8), the flap (6) moves away from the disk section (5) to allow the inhaled air to pass through the perforations such as (9) of the latter section. When air is exhaled, the flap (6) comes into contact with the disk section (5) to prevent the exhaled air to penetrate the cartridge (1) through the perforations (9) ; migration of the pollutants captured in the cartridge (1) is thereby prevented to maintain the efficiency and safety of the chemical cartridge. <IMAGE>

Title: Temperature-based rate-modulated cardiac therapy apparatus and method
Inventor: EVANS MERRY L
IPC: A61N1/365
Filed: 1990-11-14
Abstract: Evans-Fear?   1-6 Abstract of the Disclosure A temperature-based, rate-modulated cardiac pacemaker having means for variably controlling the stimulation rate of   the   heart   according   to   multiple  temperature characteristics of the blood referenced to multiple moving baseline temperatures.   A target rate  is periodically calculated by obtaining a weighted sum of the following rate components:    (1)  the magnitude of a decrease  in temperature below  resting  temperature,  a  first  moving baseline, (2) the magnitude of an increase in temperature above  a  local  minimum  temperature,  a  second  moving baseline, (3) the magnitude of an increase in the resting baseline above a daily minimum temperature, a third moving baseline, and (4) the absolute value of the rate of change of temperature.   The resting temperature is preferably calculated over a longer interval than the local minimum temperature but a much shorter interval than the daily minimum  temperature.    A  positive  rate  of  change  of temperature is distinguished from a negative rate of change of temperature and is used differently in the calculation of target rate.  The target rate is not directly applied as the new pacing rate but  is  instead averaged with the previous rate in order to provide smoother transitions between pacing  rates.   An  intermediate  rate  limit  is included in addition to lower and upper rate limits, and rank filtering is employed in the determination of rate components.

Abstract: ABSTRACT     An apparatus I call the "Sport-Trailer" is a metal frame which attaches vertically behind the rear of a vehicle ( car, van, or truck ) to carry equip-ment such as skis or bicycles. It consists of a square tubular metal tongue ( that slides in and fastens to a square tubular receptacle fixed to the rear frame or bumper ) with a vertical frame approximately 3 feet by 3 feet in dimension, welded to that tongue. The frame consists of a strong horizontal member centrally welded across the end of the metal tongue. Vertical posts are attached to each end of the horizontal bar, and cross members join the vertical posts at the top and half way down. One vertical post can be hinged to allow the frame to swing away from the vehicle for ease of loading the frame and vehicle. Ski rack, bicycle attachments or other carrying devices are then fastened to the cross members for carrying equipment. This Sports rack allows vehicles to carry skis etc. on the rear in a secure manner. It is easier to load than a roof rack especially on a high Van, and provides a safe strong carrier to reduce the practice of having sporting gear loose inside vehicles.

Abstract: This is an improved method of fabricating Zircaloy-4 strip. The method is of the type wherein Zircaloy-4 material is vacuum melted, forged, hot reduced, beta-annealed, quenched, hot rolled, subjected to a post-hot-roll anneal and then reduced by at least two cold-rolling steps, including a final cold rolling to final size, with intermediate annealing between the cold rolling steps and with a final anneal after the last cold rolling step. The improvement comprises: (a) utilizing a maximum processing temperature of 620°C between the quenching and the final cold rolling to final size; (b) utilizing a maximum intermediate annealing temperature of 520°C: and (c) utilizing hot rolling, post-hot-roll annealing, intermediate annealing and final annealing time-temperature combinations to give an A parameter of between 4 x 10-19 and 7 x 10-18 hour, where segment parameters are calculated for the hot rolling step and each annealing step, the segment parameters are calculated by taking the time, in hours, for which that step is performed, to the (-40,000/T) power, in which T is the temperature, in degrees K, at which the step is performed, and where the A parameter is the sum of the segment parameters. Preferably, the hot rolling and the post-hot-roll anneal are at 560-620°C and are for 1.5-3 hours and the intermediate annealing is at 400-520°C and is for 1.5-15 hours and the final anneal after the last cold rolling step is at 560-710°C for 1-5 hours, and the beta-anneal is at 1015-1130°C for 2-30 minutes.
