Title: Data Processing System with Read Operation Splitting
IPC: G06F13/374
Filed: 1978-10-25
Abstract: A digital data processing system includes an interconnection connected to the various elements each called a nexus, that constitute the system. For one element 32A to communicate with another element 32B, the one element, as a commanding nexus, seeks control of the interconnection and then transmits a command and address of a storage location in the other element when it receives control of the interconnection; the other element sends to the one element a confirmation signal in response to receipt of the command and address. Control is then relinquished unless the one element is to send data to the other element whereupon the data is sent immediately. If data is to be retrieved, the other element retrieves the data, requests control of the interconnection and, when it receives control, transmits the data onto the interconnection with an identification of the one element which was included in the command transmitted by the one element and has been temporarily stored in the second element. The one element then retrieves the data from the interconnection when it recognizes its own identification. If the other element is a memory element, it also contains a storage file for storing commands and data if it already is operating in response to another element command. <IMAGE>

Title: Production of carboxylic acid
IPC: C07C51/21
Filed: 1979-02-23
Abstract: Carboxylic acids are produced from carbonaceous material, such as coal, by treating a mixture of a carbonaceous material, water and a water soluble reagent comprising a Group Ia or IIa metal, with oxygen to produce a carboxylic acid salt of the metal of the reagent. The carboxylic acid salt is converted to the corresponding carboxylic acid with regeneration of the water soluble reagent. The carboxylic acid is recovered and the regenerated reagent is conveniently recycled. The water soluble reagent may be, e.g. potassium formate, acetate or propionate, and the salt is conveniently converted to the corresponding acid by treatment with an acid of such a reagent. When preparing an aromatic acid, the acid salt may be isomerized by heating, resulting in production of an isomerized aromatic carboxylic acid. In this case, benzoic acid is advantageously added to the mixture prior to isomerization, for example before oxidation.

Patent GB-2032542-A (GB)
Title: Improvements in or relating to gearboxes and transmission arrangements for small marine engines
IPC: F16D11/10
Filed: 1979-09-04
Abstract: In a gearbox of an outboard engine, drive is transmitted from the drive shaft 26 to the propeller shaft 18 by a pinion 24 and crown wheels 20 rotatable on the shaft 18. A member 32 has only two dogs 64 and moves with the shaft 18 (which is shifted by a lever 44) to engage two dogs on the axial faces of one or other of the crown wheels 20. The use of only two dogs allows more time for engagement, reducing chipping of the dogs and also permits the presence of ramps on the rear of the dogs which by cam action urge the dogs out of engagement on overrun of the shaft 18 when the engine stops. Thus automatic disengagement of gear may be achieved. Another feature is a coil spring 100 transmitting drive from the shaft 18 to the propeller 80 via projections 106, 108 located between the projecting ends 104 of the spring 100. The spring thus has a shock-absorbing function in both directions. <IMAGE>

Title: Fluid pumping and heating system
IPC: F02B3/06
Filed: 1980-11-07
Abstract: The described system utilizes a heat engine which provides shaft power and heat such as a conventional diesel engine 14 in which part of the shaft power drives a pump 11 for fluid to be heated; for example, a cryogenic liquid. The engine heat is used to heat and/or vaporize the cryogenic liquid in a heat exchanger 10. The heat available from the engine for transfer to the liquid to be vaporized is proportional to the power level of the engine. By providing a loading on the engine which is proportional to the flow rate of the cryogenic liquid, a sufficient amount of heat is provided to effect complete vaporization of the liquid, the amount of heat being directly proportional to the flow rate of the liquid. The loading of the engine can be accomplished by a power absorbing hydraulic drive 22 connected to the engine shaft with the hydraulic medium used to drive the cryogenic liquid pump. A pilot valve operates a reversing valve connected to a ram cylinder for providing a reciprocating output to drive the actuating member of the fluid pump. A surge suppression plate interconnecting the valves, ram cylinder, and loading means into a unitary structure. <IMAGE>
