Title: Sealed shot sleeve for vacuum die casting
Inventor: SCHULTZ THORNTON E
IPC: B22D17/20
Filed: 1993-01-28
Abstract: SEALED SHOT SLEEVE APPARATUS FOR VACUUM DIE CASTING   Abstract of the Disclosure A shot sleeve apparatus  for use  in vacuum die casting  is  disclosed.    The  apparatus  has  a  generally cylindrically shaped rotating collar for sealing the chamber after casting material has been poured into it.  The apparatus has a slidable plunger mechanism with an enlarged tip for forcing casting material through a shot sleeve toward the die. A flat annular collar retainer plate is located at right end of the collar.  A sleeve seal tube is attached to the collar retainer plate adapted to receive the plunger tip.  A seal housing is carried by and is slidable on the plunger stem, has an enlarged left end portion in which a sleeve seal is located so that when the plunger mechanism is moved to the left, the plunger tip enters the chamber and the seal housing and plunger stem move to the left until the seal engages the seal tube  during  leftward  movement  of  the  plunger.    Further movement of the plunger stem results in the stem sliding relative to the seal housing while the plunger tip forces material in the chamber toward the die cavity.  A vacuum is produced behind the plunger tip during movement which prevents premature flow of casting material into the die cavity.

Inventor: GREEN RICHARD
IPC: C08J7/04
Filed: 1993-03-18
Abstract: A modified elastomeric glove is disclosed having a lubricous coating made up of polyvinyl alcohol and a thickening agent.  The thickening agent is initially added in order to increase the processability of the polyvinyl alcohol coating in order to prevent runbacks and drips during the manufacturing process. A hydroscopic thickener may be used, The polyvinyl alcohol coating becomes lubricous when wetted in a water bath and therefore becomes particularly useful in applying a water-activated resin casting material for forming orthopaedic casting bandages.

Patent CA-2096184-A1 (CA)
Inventor: PURI ATUL
IPC: H04N7/50
Filed: 1993-05-13
Abstract: An adaptive technique for encoding and decoding which facilitates the transmission, reception, storage, or retrieval of a scalable video signal. The invention allows this scaling to be performed entirely in the spatial domain. In a specific embodiment of the invention this scaling is realized by adaptively encoding a video signal based upon a selection taken from among a multiplicity of predictions from previously decoded images, and a selection of compatible predictions obtained from up-sampling lower resolution decoded images of the current temporal reference. A technical advantage of the invention is that both the syntax and signal multiplexing structure of at least one encoded lower-resolution scale of video is compatible with the MPEG-1 standards.

Patent CA-2100476-A1 (CA)
Title: Hdtv receiver
Inventor: KNAUER SCOTT C
IPC: H04N19/89
Filed: 1993-07-14
Abstract: The effects of perturbations in a decoder responsive to a signal encoded in a predictive coding schema are reduced by shortening the time needed to converge the decoder's prediction signal to that of the encoder. This is accomplished by temporarily altering the leak factor when it is known that a perturbation is about to manifest itself and by, in some situations, altering the incoming encoded signalitself.

Title: Mobile waste treatment apparatus
Inventor: BAXTER RICHARD C
IPC: C02F3/12
Filed: 1993-07-14
Abstract: ABSTRACT OF THE DISCLOSURE         A sequencing batch waste treatment facility with pretreatment mixing and equalization by mixing with bacteria to achieve a selected waste to bacteria ratio includes selective bacteria breeding through a waste feedback loop, wherein waste is treated and reduced to acceptable biological oxygen demand levels for municipal type waste treatment or general discharge per regulatory permit.

Patent CA-2103633-A1 (CA)
Title: Waste processing machine
Inventor: BATEMAN IVOR
IPC: B02C13/04
Filed: 1993-08-09
Abstract: WASTE PROCESSING MACHINE                ABSTRACT OF THE DISCLOSURE         The invention is a waste processor which incorporates the advantages of the chipper knife holder 100, swing hammers 50 and hog 120. A swing hammer 54 is used, providing for the use of all the kinetic energy stored in the swing hammers 54 together with good material contact. The swing hammer 54 profile is designed to spread the impact force over a large area, thus increasing the life of the swing hammer 54.  If necessary, the swing hammers 50 can be locked to the rotating disk assembly 18, preventing their contacting any material.  Hog hammers 120 are placed immediately behind the swing hammers 50.  The position of the hog hammers 120 is such that they provide room for the swing hammers 50 to recoil, but are close enough to impact the material in approximately the same place as the swing hammers 50.  The hog hammers 120 use the much larger amount of kinetic energy that is stored in the rotating disk assembly 18.  The disks have material guides 158 at their outer periphery for directing the mulch material laterally to prevent the mulch material from accumulating at the periphery of each disk 40 and between the disks 40. A choke plate 156 provides for altering the size of the outlet opening during operation of the waste processor to substantially control the size of the particle expelled from the waste processor.

This is followed by a duct section having a relatively low flow rate on the surface, in which the flow is dammed up at an obstacle at a liquid level constant with time, so that an ultrathin, ordered layer of amphiphilic molecules is continuously formed in these duct sections at the polar liquid/air interface by compression of the flow. The washed over ramp is movable.

Patent CA-2110457-A1 (CA)
Title: Clutch Mode Control Logic
Inventor: SLICKER JAMES M
IPC: B60W30/18
Filed: 1993-12-01
Abstract: A friction clutch (20) coupling an engine (10) and a gear transmission (30) of a vehicle is controlled by a microprocessor based circuit using logic which defines operating modes according to engine (10) and clutch (20) conditions.  During the time of clutch closure, when the vehicle is starting from rest in a startup or launch mode, the throttle or other engine control signal is restrained from quickly responding to the accelerator pedal  (11).          This  avoids  engine  overspeeding  which  results  from generating high torque before sufficient clutch capacity has been achieved.  The control signal is developed as a function of the pedal position under control of throttle logic which,  in turn,  is dependent on clutch operating modes defined by the clutch logic.  The clutch operating modes  are  four  modes  for  automatic  clutch  operation comprising touch point approach mode which prohibits a throttle signal during initial clutch movement, creep mode or startup mode after touch point (81) occurs, and lockup mode for completing clutch closing when low clutch slip is attained.   A non-automatic mode is entered before the accelerator pedal (11)  is depressed or when engine (10) stall conditions are detected.

Patent CA-2117421-A1 (CA)
Inventor: BRADFORD ROBERT W
IPC: G02B21/00
Filed: 1992-01-29
Abstract: A microscopy system designed to achieve upwards of 12,000X magnification with simultaneous high resolution of better than 0.3 microns and over 30 microns depth-of-field. The microscopy system utilizes a conventional research microscope having a plurality of objective magnification lenses that produce the initial magnification with acceptable limits of high resolution and depth-of-field.  A projection housing is combined with the research microscope in a unique manner where it receives the initial magnification and greatly increases that magnification while still maintaining the high resolution and depth-of-field obtained during the initial magnification.  A light source used to illuminate the specimen platform from its underside is located remotely therefrom and connected by a fiber optic cable to a condensing lens positioned beneath the specimen platform.  This allows for high intensity lighting of the specimen while keeping it away from the detrimental heat of the source of high intensity light.  The projection housing has projected image receiving means therein whose distance from its projection lens can be varied to vary the magnification produced by projection.
