Patent CA-2213065-A1 (CA)
Inventor: VAN ECK DARRELL
IPC: C23F15/00
Filed: 1997-08-14
Abstract: A method is disclosed of protecting a land or roadway vehicle body from surface corrosion which causes pitting, blistering, and other defects in paint at the joints in the skin, where the body surface is comprised of dissimilar metals in its skins and stringers and in the fasteners therefor.      Roadway vehicles such as ambulances and fire trucks often have aluminum skins fastened with stainless steel screws, bolts, or rivets to aluminum structural members to save weight, but corrosion thereof is a persistent problem. The new method comprises using an antioxidant, a heavy grease compound with metallic zinc dispersed therein as dust or powder, such as electrical joint compound, as a bedding compound applied to surfaces of the fasteners or to the insertion apertures therefor before assembly. In one commercial form, the compound comprises about 51-53% by weight zinc, about 36% by weight refined heavy paraffinic distillate, and about 11-13% by weight aluminum stearate. The assembled surfaces will resist corrosion better, and for years longer, than surfaces assembled by other methods.

Abstract: A refrigerant reservoir (23') and heat exchanger unit  (25) for a refrigerated counter  (11)  and method of reducing compressor load and lowering energy consumption of the  refrigerated  counter  system  is  described.    The refrigerant reservoir  (23')  and heat exchanger unit  (25) comprises  a  reservoir  having  a  heat  exchanger  section provided with a cooling coil (26) to cool liquid refrigerant from a condenser (14) as it enters into the reservoir (23'). The reservoir is secured in a cooled area of a refrigerated counter  (11).   The outlet (31) of the reservoir feeds an expansion  valve  (29)  where the  pressure  of  the  liquid refrigerant   is   lowered  to  further  cool   the   liquid refrigerant.   The expansion valve (29) has an outlet (28) which is connected to the inlet (17)  of the cooling coil (26) whereby the cool refrigerant liquid in a feedback path, cools refrigerant entering the reservoir.

Patent CA-2233877-A1 (CA)
Title: Adaptive controller for injection molding
Inventor: SPAHR DAVID K
IPC: B29C45/77
Filed: 1996-10-01
Abstract: An adaptive controller (42) is provided for controlling the transition, in an injection molding apparatus (10), from the injection stage to the packing stage. The controller operates by controlling the velocity of the ram (32) during the injection stage, and controlling the ram pressure during the packing stage. The controller (42) anticipates the transition from the injection stage to the packing stage by monitoring the ratio of pressure to velocity. The divergence of this ratio forecasts the onset of the packing stage. At this time, a pressure relief valve (46) is preset in anticipation of the packing stage, to prevent a pressure spike during the transition period.  The flow control valve (40) is held constant during the transition.

Title: Access to communications systems
Inventor: FREIBERG LORENZ
IPC: H04L12/56
Filed: 1998-09-30
Abstract: The invention relates to communication systems in which end-user devices contend for access to shared resources of a channel in the communicationsystem. End-user devices sending data in packets over the communication channel piggyback requests for changes in allocated resources for transmission of another packet. A system controller changes the resource allocated to individual end-user devices depending upon the piggyback requests, in order to optimise the throughput of the channel. A packet switched network may thus act like a circuit switched network if required.
