IPC: F27D1/12
Filed: 1979-06-15
Abstract: A cooler for use in a furnace comprises a main body (10) formed of a first metal e.g. copper, the main body defining a cavity for coolant flow therethrough and having inlet and outlet openings (14, 16 respectively) for coolant communicating with the cavity, pipes (24) secured in said inlet and outlet openings, and a member (26) secured in gas-tight relationship to said pipes (i.e. welds 28) and adapted to be secured in gas-tight relationship to the shell of a furnace.

Patent GB-2024973-A (GB)
Title: Tube Fitting Assembly With Deformable Seal
IPC: F16L13/16
Filed: 1979-06-18
Abstract: A tube fitting assembly is disclosed wherein a ductile metal tube 17 is forced into first and second orifices 23 and 24 within a fitting 16. The tube 17 is closely received within the first orifice 23 and the second orifice 24 is larger so that the axial force on the tube axially contracts the tube to form a radially expanded bead on the tube substantially filling the second orifice. This establishes a fluid tight seal between the tube and the fitting and also retains the tube in the fitting. An annular deformable seal member 28 is also provided between an outer surface of the tube and an inner surface of the fitting and this seal may be a rubber-like O-ring or a composition material which is more yieldable than the material of the tube and fitting, may be set up from a liquid or plastic sealant material, or may be a deformable wall of the fitting. The force used to axially contract and radially expand portions of the tube is also utilised to compress the deformable seal between an outer surface of the tube and an inner surface of the fitting to make doubly sure of a good fluid-tight seal. The tube fitting assembly is thus able to withstand higher pressures, suddenly applied pressures, corrosive fluids, and extreme and rapid changes in temperature, with only a negligible number of failure of the assemblies. <IMAGE>

Abstract: A process is provided for conditioning (i.e. adjusting the moisture content and temperature of) particulate foodstuffs such as cereal grains which in by cooling the foodstuffs below ambient temperature allows them to be stored without deterioration although the moisture content remains higher than permissible for such storage at ambient temperature. In the process the foodstuff is heated in a first air current to reduce the moisture content, and is then refrigerated to below ambient temperature in a second air current, the heat abstracted in the latter step being recycled to preheat the first air current, thereby minimising the energy demand of the process. Apparatus for carrying out the process comprises a tower or silo (1) adapted to contain a slowly descending column of the foodstuff, means (3,4) for heating an upper region of the column with a first air current, means (9,5) for refrigerating a lower region of the column with a second air current, and heat exchange means (16) for recycling heat abstracted from the second air current to preheat the first air current. <IMAGE>

Title: Digital processor
Inventor: MCWILLIAM ANDREW JOHN
IPC: G06F17/10
Filed: 1983-04-14
Abstract: To read out a sequence of words in a random access memory (RAM) a base address of the first word to be read is placed in a register unit and a number to be added to that first word to form a memory address is placed in a pointer register. These two are then added and the result used as the first address. On each of a number of subsequent steps (the number being held in a "sequence-length" register) the pointer register is incremented (or decremented), and the indexing process repeated. As described, there are two RAMs (RAM 1, RAM 2) and two address units (DAU1, DAU2) so controlled that in each step two words are read out, one from each RAM, for a processing operation e.g. to implement a transversal filter. Where several processors are used in a multiprocessor system they are selectively interconnected by a System Bus under the control of Bus Arbitration Logic, for data transfer via memory access processors DMA CPU. <IMAGE>
