Patent CA-2025361-A1 (CA)
IPC: A61F5/055
Filed: 1990-09-14
Abstract: A soft neck support collar is disclosed comprising two offset and attached,  tubular ring elements,  each element hooking together at their respective ends.  Both ring elements contain a soft fill material such as nylon, cotton, polyester, acrylics, foam, foam chips, etc.  The combined effect of the fill material together with the tubular configuration, enables the neck to adjust for lateral forward and backward forces during movement.  The upper ring element is tapered at each end, so that when these ends are joined together, a space is formed into which the chin can fit, thereby maintaining the neck in a neutral position, and preventing hyperextension.          The lower ring element is hooked together at each end, and the rings are offset to enable the lower ring to close at the back of the neck, approximately opposite from the closure of the upper ring element.  Hence, the lower ring element functions as a continuous, uniform, tubular-shaped ring which does not interfere with movement of the chin.   Thus, in the closed configuration,  the neck support collar allows for neutral positioning of the chin and neck, and restricts neck mobility.

Title: Apparatus for the size identification of objects
Inventor: KASSFELDT HILLAR
IPC: G01N21/84
Filed: 1991-01-04
Abstract: ABSTRACT          Small objects, particularly coins, are identified as to their size by passing them in a movement path through an area measuring light path consisting of a monolithic photovoltaic cell, such as a solar cell, and a light source on opposite sides of a narrow path.  The area of the measuring path occluded by the object shadow as it falls on the photovoltaic cell is measured and compared with a table stored in a controlling microprocessor, the object being accepted if the measured area is within predetermined limits.  Preferably an edge portion detector is disposed ahead of the area measuring light path and the area is measured as the edge detector detects the edge, reducing the size of photovoltaic cell that is required.  In a battery operated apparatus intended for coin-operated newspaper vending boxes, in order to maximize battery life, the detectors and the microprocessor are quiescent until an object detector, cycled by a clock to reduce its duty cycle, detects an object in the movement path.  Upon such detection a maximum reading is taken with the area detector fully illuminated and unoccluded, which is then used to recalculate the acceptance/rejection limits to compensate for changed ambient conditions and component changes.  A minimum reading with the path not illuminated may also be taken.  A new latch mechanism for a newspaper vending box is also disclosed.

Title: Shaft locking or manual operating apparatus
Inventor: BAKER GERALD S
IPC: F16K31/143
Filed: 1991-07-19
Abstract: A manual operator which is useful when used with a valve or other type of device to provide either manual operation of the valve in one direction or to provide a stop against the movement of the valve away from one of its extreme positions. The device includes a ball nut (60), screw shaft (62) and balls (64) positioned in facing grooves in the nut and shaft so that relative rotation has very low friction. Thus rotation of one of the nut or screw shaft results in axial movement of the screw shaft (62) so that it can move or provide a stop. Aligned adjacent exterior surfaces are provided on a rotating part of the device and one a stationary part of the device which surfaces are engaged by a locking spring (76) which can be release from such surfaces when it is desired that the manual operator cause an axial movement of screw shaft (62). In one form of the invention the screw shaft rotates and the ball nut is stationery. In another form the ball nut rotates and the screw shaft is stationary. In a third form two locking springs are provided to lock against inadvertent relative rotation in both directions. In still another form of the apparatus, it is applied to a blowout preventer ram tail rod so that the axial movement of the tail rod is translated into rotation of a ball nut and a spring engages a surface rotating with the ball nut and a stationary aligned surface to prevent relative rotation in one direction to lock the tail rod with the piston in its inner or ram closed position.

Title: Mobile-telephone system call processing arrangement
Inventor: BOLLIGER BRIAN D
IPC: H04Q11/04
Filed: 1992-04-21
Abstract: A CDMA cellular radio-telephone system (FIG. 2) comprises a packet-switched communications network (202, 207, 201) that interconnects cells (base stations; 202) with each other and with the public telephone network (100). A unique combination of a static addressing plan that uses a different LAPD DLCI (302 in FIG. 7) for each unidirectional virtual call path, direct cell (202)-to-cell and cell-to-call-processing unit (264 in FIG. 5) control information exchanges, and packet-switching techniques that permit call traffic and control communications to share call paths and permit different call paths to share physical resources, is applied to call processing. This enables soft handoffs (FIGS. 27-29) to be handled in a manner transparent to the parties to the call and without significant involvement of system control elements (134 and 261 in FIG. 2) whose involvement would adversely impact the system's call-handling capacity. It also enables soft handoffs to occur without change of the call processing unit that is handling the call, so that a single call processing unit continues to handle the call from start to finish through even multiple soft handoffs.

Title: Process for preparing oligomers having low unsaturation
Inventor: SANDERSON JOHN R
IPC: B01J21/16
Filed: 1992-04-22
Abstract: ABSTRACT (D# 81,069-F) Synthetic lubricant base stocks may be prepared in good yield by oligomerizing linear olefin monomers using certain acidic calcium montmorillonite clay catalysts.  When the oligomers are prepared at a temperature greater than about 200 °C,  and any unreacted linear olefin monomer is removed, oligomers having an iodine value less than about 3 mg/g are obtained.  An even lower iodine value is obtained when a hydrocarbon possessing a tertiary hydrogen is mixed with the linear olefin feed, and the mixture is contacted with the clay at a temperature greater than about 200°C.          Little or no hydrogenation may be required of oligomers prepared in this manner to obtain base stocks suitable for use as synthetic lubricants.

Title: Method for recovering spent foundry sand by roasting
Inventor: FUMAGALLI PIO
IPC: B22C5/00
Filed: 1990-11-23
Abstract: The method permits recovery of spent foundry sand for reuse by eliminating, by combustion, the organic carbon substances with which the spent sand is impregnated; spent sand, after grinding to a uniform grain size, is placed into a cylindrical container (2) inclined with respect to the vertical and rotated slowly (4-6 revolutions per minute); then, a stream of oxygen is blown into the base of the receptacle through a distributor (5) which uniformly distributes it into the spent sand mass (20), and local combustion is initiated on the surface of the sand mass, at the top of receptacle, by means of a burner (31); finally the burner is extinguished whilst the delivery of the oxygen stream is maintained and the combustion proceeds and feeds itself by the effect of a progressive descent of the flame front (30) towards the base of the receptacle until complete destruction of the organic and carbon substances contained in the sand has taken place.
