Inventor: SANFORD GARY G
IPC: H01Q9/04
Filed: 1978-09-22
Abstract: Method and apparatus for improving the r.f. isolation between a transmitting (10) and receiving (12) microstrip antenna disposed at respectively correspondingly spaced apart but relatively adjacent locations. A special compensation radiator (26,28,30) is provided at the transmitting and/or receiving antenna site and fed from the same r.f. input/output (20) which feeds the main antenna (16). The direction, magnitude and phase of r.f. energy radiated and/or received from the compensating radiator are chosen so as to substantially cancel the undesirable r.f. energy otherwise directly received by the receiving antenna from the transmitting antenna.

Inventor: SPENCER GARY ALAN
IPC: G11C29/02
Filed: 1979-11-29
Abstract: The memory modules of a computer are provided with means for checking the operation of the addressing circuits under program control. Normally such checking involves writing into the memory array, reading the data and comparing the read-out data with that originally written. This has the disadvantage that a large amount of temporary storage must be provided for the information displaced from the memory array. Further, the results may be ambiguous, in that it may be impossible to distinguish between an error due to failure of the addressing circuits and that due to a defect in the memory array itself. 
     The invention provides a mode setting means (31) by means of which the program is enabled to set one or more digits in a status register (21) in the memory module, so placing the module in a maintenance mode. In this mode, when a read instruction from the central processing unit (10) is addressed to the module, instead of its being used to address the appropriate location in the memory array (22), the address in the instruction, or a portion of it, is returned, thus enabling the functioning of the processing and addressing circuits in the memory interface to be checked without involving any writing into the memory array itself. 
     Two digit positions of the status register (21) may be used, one of them when set causing a part of the read instruction address to be returned, and the other when set causing the remainder of the read instruction address to be returned. When neither digit is set memory addressing proceeds in the normal manner.

Abstract: Simplified type of skirt adaptable to all vehicles or objects to be moved on a cushion of air, formed on blocks level with the vehicle. This skirt consists of a piece of fabric (1) laid flat and stretched out over wooden blocks (4) arranged temporarily at the corners of the perimeter of the base of the object or vehicle to be moved (3), these blocks being of the desired depth of the skirt. The fabric is then draped around the blocks and folded up and fastened to the perimeter of the base of the vehicle or object to be moved. The bag thus formed is opened over an area cut out from its horizontal portion following the perimeter of the base but with rounded corners and of a smaller diameter than the perimeter of the base. This gives a peripheral skirt with concave walls and a stable geometry. The invention may be used to move, on a cushion of air, toys or handling pallets or for moving exceptional objects (houses, containers). <IMAGE>

Abstract: Compensation in a receiving arm of a four-wire line arrangement for cross-talk and echo interference due to signals (S) in the transmitting arm is provided by means of a ROM S in which are stored coded compensation signal values ??? derived empirically when the relevant system is first used. A pulse generator T, using the transmitted pulses d as clock pulses, drives the ROM S to read out the appropriate compensation signal values ??? which are decoded in a decoder D which supplies the resulting compensation signals K to a subtractor V which subtracts the compensation signals k from the received signals e. In an alternative form distortion of received signals is corrected by means of a similar pulse generator- ROM-decoder arrangement in which the pulse generator is driven by the distorted received signals and the decoded compensation signals are added to the distorted signals. <IMAGE>

Abstract: A process for producing ethanol from the reaction of methanol, hydrogen and carbon monoxide catalyzed by a phosphine-iodine promoted cobalt-ruthenium catalyst, the improvement of maintaining the phosphine to halide ratio and concentration within a critical range, and whereby the concentration of phosphine compound in the reaction mixture is increased without causing an undesirable decrease in the activity of the catalyst; thereby obtaining a highly stable and active catalyst providing an increased selectivity to ethanol formation. This is accomplished under such conditions that the catalyst stability is maintained and the ratio of phosphine to halide is kept at a relatively constant value during the reaction.

Abstract: A clock generator for producing a two phase output comprises a bistable circuit having two stages. The output of each stage is cross coupled to the input of the other and each cross coupling path includes a high-resistance transfer gate. Each transfer gate forms part of an RC delay element which is so arranged that at a transition of clock signals the output of one of the stages completes its transition substantially at the same time as the output of the other stage begins its transition. This results in non-overlapping outputs from the generator.
