Patent EP-0044065-A2 (EP)
Inventor: JOHNSON OLIVER WENDELL
IPC: B62D5/09
Filed: 1981-07-13
Abstract: A system is disclosed for controlling the flow of fluid from a pair of pumps (15,15') to a steering system (11) and a pair of auxiliary load circuits (13,13'). The steering system includes valving (43) defining a variable flow control orifice (45), and the steering system normally operates with a pressure differential X across the variable orifice, and provides load pressure signals (47,49,49',53,53') representative of demand for fluid by the steering system. Fluid flow from the pumps is controlled by a pair of priority flow control valves (21,21') including a pair of valve members (27,27') each of which is biased by a spring (29,29') toward a position permitting flow to the steering system. The spring (29) exerts a biasing force equivalent to the pressure differential X while the spring (29') exerts a biasing force equivalent to a pressure differential Y, which is less than X. When the output of the pump (15) is unable to maintain the pressure differential X across the flow control orifice, the differential across the orifice drops to Y, at which point the valve member (27') is biased by the spring (29') to permit flow from the pump (15') to the steering system.

Abstract: The present invention relates to minehunting and disposal systems. Known methods of minehunting and disposal comprise the deployment of several relatively large ships each having a crew of the order of thirty personnel. The known ships are expensive since they have to be specially fabricated so as to present a low magnetic signature and low noise generation. 
     This invention provides a system comprising a parent ship providing support facilities for a plurality of operational craft (10, 12, 14, 16), the operational craft (10, 12, 14, 16) being relatively small and being provided with known mine detection and destruction equipment (34). The parent ship is preferably designed and equipped so as to be capable of carrying the operational craft (10, 12, 14, 16) on board, such that the operational craft may be transported to the area of deployment. The operational craft (10, 12, 14, 16) preferably have hulls (16) providing a substantial portion of its buoyancy submerged together with a relatively small water plane area, for example a Small Water Plane Area Twin Hull type craft. 
     This system reduces the number of personnel exposed to a single risk and the operational craft present a low magnetic signature and low noise generation due to their size and these endowments are particularly enhanced if the preferred form of hull (16) is utilised.

Abstract: A field maintenance processor including a microprocessor that effects transparent refreshing ef a-dynamic memory includes a counter circuit which times the duration of the «wait» signal produced by a slow memory or a slow peripheral device accessed by the processor. The counter circuit produces a «wait enable» signal which enables the «wait» signal to produce an «enabled wait» signal that is conducted to a wait input of the processor for only a predetermined time, to ensure transparent refreshing of the entire dynamic memory. If the «wait» signal produced by the slow memory device has not ceased when the predetermined time has elapsed, the «wait enable» signal disappears, causing the »enabled wait» signal also to disappear. The disappearance of the «wait enable» signal also causes a «wait interrupt» signal to be generated and transmitted to the microprocessor, resulting in execution of an interrupt routine to determine which instruction execution was earlier halted in response to the «enabled wait» signal. The entire dynamic memory is transparently refreshed during execution of the interrupt routine.

Abstract: A switching apparatus is described, especially a contactor, which has at least one double-contact point (6, 7) to which at least one semiconductor valve (4) is connected in parallel. Because of the arc which occurs on opening of the double-contact point, the semiconductor valve (4) is driven such that the arc current is commutated on the semiconductor valve and is extinguished by the semiconductor valve as it passes through zero. The arc is used to trigger the semiconductor valve; in this case the control connection is connected via a braided cable to the contact link. <IMAGE>

Abstract: A method of forming an aperture of a predetermined shape into a dielectric substrate which wilt lockingly receive a deformable contact pin is described. It includes providing a dielectric material having a coefficient of shrinkage responsive to a heat treatment which coefficient is different in one direction from that in another direction and which irreversibly change dimensions in its two orthogonal directions in proportion to the difference in theirtwo coefficients of shrinkage. An aperture is formed in such a material, in a direction normal to the plane of the two orthogonal directions and the material is subjected to a heat treatmentthat causes a differential shrinkage in the aperture and a change in the shape of the aperture. A deformable contact pin (29) is then forced into a locking position in the aperture. By using such a method to lock a contact pin (46) in close proximity to a conductive line (49) extending across the substrate (52) or by having the aperture and the pin extend through the substrate, electrical circuits on one side (51) of the substrate can be contacted through a contact pin (46) on the opposite side (53) of the substrate (52).

Abstract: A layer of electron sensitive resist (13) on a semiconductor substrate (12) is exposed to a patterned electron beam emitted from an erasable photocathode mask (6, 9) in an electron image projector (5). The mask is formed from a transparent, e.g., quartz, plate (6) on which is provided a layer (9) of caesium iodide or other photoemissive material. A photoemissive pattern is defined in layer (9) by selective direct exposure to a beam of photons, electrons or ions preferably in an evacuated carbon-containing environment whereby the photoemission of the exposed areas of the caesium iodide is lowered. Alternatively using a beam of charged particles with a relatively high current density the exposed parts of the caesium iodide are actually removed by evaporation. In both cases, the patterned caesium iodide can be removed by rinsing in water and the transparent plate (6) can be reused with the same or different photoemissive pattern.

The bit line load includes a bit line clamp (30) combined with a bit line current source (32) regulated by a voltage reference (VR1) which tracks changes in transistor characteristics. Separate data read lines (24, 26) and data write lines (20, 22) are provided, with a differential amplifier (40) for each pair of bit lines. The data read lines (24, 26) are coupled to compensated current source loads (48, 50), and the differential amplifiers (40) are coupled to switching transistors (52, 54) which are also compensated for transistor characteristic changes. Each bit line pair (14, 16) has a sneak capacitance prevention transistor (66) so that in non-selected columns the bit line pairs are coupled together allowing the memory cells therein to pull down all of the bit lines. This isolates the read lines from unwanted capacitance in the differential amplifiers of each of the non-selected columns. Further, a VCC protection circuit (Figure 4) is provided.
