Patent GB-2020487-A (GB)
Title: A reed contact unit
IPC: H01H1/66
Filed: 1979-05-31
Abstract: A magnetically actuatable reed contact unit has two electrodes extending into an hermetically sealed enclosure to overlap at a contact region and at least one of the electrodes is provided with an enlarged end portion so as to increase magnetic mass at the contact region and thereby increase contact forces during actuation and in the closed position of the contacts. In this way the magnetic circuit of the contact unit can be constructed independently of the mechanical deflection system thus allowing the use of special magnetic materials for the contact element which do not have to have the required physical characteristics for glass to metal sealing. The elements of the contacts can be selected to fulfil a particular function of the switch such as magnetic holding when a hard magnetic material is used, high sensitivity when a highly permeable magnetic material is used, a soft iron for low remanence and a permanent magnet for normally closed contacts. <IMAGE>

Title: Test means and assay for deter- mining the urea content of fluids
IPC: G01N33/62
Filed: 1979-06-08
Abstract: Test means, method for making same and method for assaying the urea content of fluids such as blood serum, plasma, urine and spinal fluid are disclosed. The preferred method for making the test means involves a three stage application of reagents separated from each other on an acid modified carrier matrix. One reagent is o- phthalaldehyde and the other reagent is 3-hydroxy-1,2,3,4-tetrahydrobenzo[h] quinoline, 3-acetoxy-1,2,3,4- tetrahydrobenzo[h]quinoline or their dihydrochloride salts. Stability of the reagents is achieved and precipitation of serum proteins is avoided. Moreover, the interfering color due to the presence of bilirubin is minimized when the urea content of serum is determined.

Title: Adjustable bar stock feed
IPC: B23B13/02
Filed: 1979-06-21
Abstract: An adjustable bar stock feed mechanism includes a stock pusher 28 to push the bar stock to the spindle of the machine tool and an actuator means is provided, such as a spring 59 urging the stock pusher forwardly as controlled by a stock feed cam 38 and cam follower 39A.

A flexible cable is connected to actuate the stock pusher and encompasses part of the cable pulley and then has a variable anchor 44 on an involute curve 46 as a fixed anchor point on the frame of the machine. By changing the anchor point 44 along this involute curve 46 a continuously variable amount of feed of the bar stock is achieved with a constant forward feed position of the stock pusher. <IMAGE>
Patent GB-2029145-A (GB)
Title: Non-volatile word-wise electrically erasable stores
IPC: G11C16/02
Filed: 1979-06-28
Abstract: A word-wise erasing non-volatile store has a matrix of storage cells (100, 200, 300, 400) e.g. field effect transistors with floating gates. Appropriate voltages for erasure are applied to the gates of the selected cells (via transistors 166, 366) and to their sources (via transistors 122, 222). In order to obviate the need for an external timer and to avoid the erasing voltages being applied for longer than necessary, analysis means (129, 229) are provided for each cell, to indicate when the cell has reached its erased state. As shown these each comprise a flip- flop which senses the resulting drop in drain voltage, and changes state to terminate (via gate 125 and transistor 121, or 225 and 221) application of erasing pulses to the source of the cell. <IMAGE>

Title: Deceleration-responsive control valve
IPC: B60T8/28
Filed: 1979-07-03
Abstract: A valve for use in a vehicle hydraulic brake system to limit the rear wheel brake pressure at outlet 29 relative to the front wheel brake pressure at inlet 26 to reduce the potential for premature rear wheel lock includes a proportioning piston 58 which co-operates with a seal 73 to control the fluid pressure delivered to the rear wheel brakes an inertia member 48 which senses changes in vehicle loading and a by-pass check valve (Fig. 2a). When a vehicle is fully loaded, the inertia member 48 remains as shown in a position where it will obstruct (and be trapped by) the proportioning piston in its open position and, consequently, the rear wheel brake pressure will be equal to the front wheel brake pressure. When the same vehicle is unloaded, the inertia member 48 moves in response to deceleration to a position clear of the proportioning piston in its open position so that the rear wheel brake pressure will be reduced relative to the front wheel brake pressure. The by-pass valve (which includes a hexagonal element 88) opens at a preset pressure difference between inlet and outlet pressures to limit the difference. An anti-surge valve 96 prevents the piston 58 from trapping the ball 48 on initial brake pressure rise. The by-pass valve may be parallel to the proportioning valve (Fig. 10). The ball may be engaged by a spring plunger which is withdrawn by increasing inlet brake pressure (Fig. 11). A dual circuit arrangement (Fig. 12) includes an inertia ball within a U- shaped spring acting on opposed co- axial proportioning valve pistons. <IMAGE>

Title: Boundary layer control device
IPC: B64C3/14
Filed: 1979-07-16
Abstract: A boundary layer control mechanism primarily for aerofoil-type surfaces, in which one or more steps are formed in the surface. The step consists of a step recess followed, in the flow direction, by a ramp return to the surface contour. A number of such steps in succession on the suction surface of an aerofoil cause early, controlled separation of the boundary layer at each step, followed by re- attachment during each ramp.The boundary layer is thus continually 'nudged' into a condition which is resistant to gross separation. Applicable to turbine or compressor blades of turbo-machinery. Similar steps and ramps may be provided in the drum on which the blades are mounted. <IMAGE>

The said position is preferably midway between the ends of the respective other link. The other links 12, 16 are preferably pivotted at their ends remote from the pin 18 one to a base 10 and one to a load engaging head 20 of the jack. In a modification, Fig. 6, one of the links 228 extends beyond the parallelogram and engages in a straight guide slot 52 in the base. In a further modification (Fig. 8), a curved guide slot (54) is used. The links may be flat or of channel section. <IMAGE>
Patent GB-2060805-A (GB)
Title: Wall anchor
IPC: F16B13/08
Filed: 1979-07-26
Abstract: A wall anchor consists of a rod which is threaded at one end to receive a nut and carries a transversely extending bar at its other end, which bar is less than 10 mm thick measured transversely of the rod. The anchor is intended for connecting the inner wall of an existing cavity wall to an adjacent structural member such as a floor joist. A hole is first drilled through both the outer and inner walls, on a bedding joint of the outer wall, and a slot is made in the outer wall by removing mortar of that bedding joint. The anchor is then passed through the slot, threaded end first, and brought to a position where its threaded end projects through and beyond the inner wall for connection to the floor joist. Once the bar has passed completely through the slot the anchor is rotated automatically by the bar, which has arms of unequal lengths, to bring the bar to a vertical position. The outer wall can then be made good with mortar.

Title: Linear semiconductor resistor
IPC: H01L29/8605
Filed: 1980-03-12
Abstract: A diffused semiconductor resistance structure has a resistance value that is practically independent of applied voltage. The structure includes an isolation layer 22 diffused into an underlying substrate 12, a resistance layer 20 diffused into the isolation layer, and a conductive element 30 connecting the isolation layer to an electrical contact 28 near the midpoint of the resistance layer. The junction between the resistance layer and the isolation layer is thereby zero-biased at its midpoint, is forward-biased on one side of the midpoint, and is reverse-biased on the other side of the midpoint. Consequently, the average thickness of a depletion region formed at the junction, and the average effective depth of the resistance layer, are maintained constant and practically independent of applied voltage, to provide a resistance value that is also practically constant. Undesirable high forward bias voltage allows the junction between the isolation layer and the resistance layer is avoided by connecting the diffused semiconductor resistance structures in series. The series connected arrangement may be used in a monolithic digital-to-analogue converter. <IMAGE>
