摘要： Supplementary cooling for a mechanical refrigeration plant using ammonia as a refrigerant is provided by placing a tube in the vapor space of a buffer vessel and introducing liquid nitrogen into the tube. Although ammonia solidifies at -78.degree. C. and liquid nitrogen enters the tube at -196.degree. C. no ammonia solidifies on the tube even after extended operation. The present invention also provides a method of refrigeration which comprises introducing liquid nitrogen into the heat exchanger of a refrigeration apparatus in accordance with the invention and condensing refrigerant therewith. Preferably, the refrigerant is selected from the group consisting of ammonia and fluorocarbon R22.

摘要： A tunnel freezer is cooled by selectively supplying liquid nitrogen to banks of spray nozzles. The banks are switched on and off as required so that at any given time the pressure upstream of each operational spray nozzle will be substantially constant at a level which closely approximates the maximum heat transfer coefficient associated with the spray nozzle or the maximum effectiveness of the spray nozzle or a balance therebetween. The invention is in contrast to the prior art where the flow of liquid nitrogen to the spray nozzles is continuously varied in response to the thermal load.

摘要： The present invention relates to a novel composite adhesive used to adhere coating materials onto a substrate wherein the substrate material and the coating material have significantly different expansion properties, e.g., thermoplastic coating materials onto cellulose based substrate materials. The composite adhesive comprises both a rigid adhesive such as an epoxy or acrylic and a laminating adhesive such as a rubber based contact cement. In a preferred embodiment of the invention, the composite adhesive is used in preparing composite articles such as counters, sinks, furniture, profile edging, chemical resistant lab tops, showers, etc. In another preferred embodiment according to the invention, the rigid adhesive is applied over a narrow portion of the coating material, substrate, or both, preferably the exterior region of said material, and the laminating adhesive is applied over the remainder of the surface area to be adhered. By the techniques of the present invention, it is also possible to adhere together several individual articles of manufacture so as to create a virtually seamless appearance between the individual articles of manufacture.

摘要： A refrigeration system using air as the refrigerant comprises a compressor which compresses air to 84 bar g. The compressed air is cooled first by cooling water and then by returning air in a plate-fin heat exchanger before being expanded to 59 bar g in an expander. The expanded air at -61.degree. C. is passed through indirect cooling coils in a cold store which it leaves at -45.degree. C. This air is then passed through the plate-fin heat exchanger before being recycled to the compressor. The refrigeration delivered is about 1.05 kw refrigeration/kw power input.

摘要： A dispenser for cryogenic liquid comprising a vacuum insulated vessel (2) which is provided with a dispenser tube (10). The dispenser tube (10) is heated in use by an electric heater (11). Sufficient heat is supplied to achieve film boiling on the inner surface of the dispenser tube (10). Flow of cryogenic liquid from the vacuum insulated vessel (2) into the dispenser tube (10) is controlled by a tapered valve member (14) which is biased downwardly by a spring (15) and which is connected to a permanent magnet (16) disposed in a coil (17). The tapered valve member (14) can be driven upwardly or downwardly according to the sense in which a direct current is applied to the coil (17). A gas relief tube (18) is provided to vent gas from the dispenser tube (10) intermediate the tapered valve member (14) and the outlet of the dispenser tube (10). The gas relief tube (18) conveys gas to the space above the cryogenic liquid, for example liquid nitrogen, in the vacuum insulated vessel (2). The dispenser has particular utility in high speed canning and bottling lines.

摘要： In a method of forming a frozen food product, the temperature of a fluid food product is lowered so that the product is plastic. A mould is pressed against the food product to cause at least a portion of the product to take up the shape of the mould. The mould is at a sufficiently low temperature when it is pressed against the product such that the product retains its moulded shape and such that the product is readily releasable from the mould. This allows frozen confectionery products such as ice cream to be successfully moulded.

摘要： A turbulence inducing fan blows cold gaseous nitrogen through ducts disposed to either side of a conveyor carrying product to be frozen through a freezing tunnel. The cold gaseous nitrogen is deflected downwardly onto product on the conveyor by a baffle having, in cross section, the form of a cusp. The cold gaseous nitrogen forms two counter-rotating vortex. The cold gaseous nitrogen travels across the product and then passes into an intake cowl primarily via inlets disposed adjacent both edges of the conveyor. The intake cowl collects the cold gaseous nitrogen which is sucked into the intake of the turbulence inducing fan. This arrangement provides excellent heat transfer to the product being frozen.
