Title: Gasket for an Avionics Tray
IPC: B64D43/00
Filed: 1979-11-30
Abstract: A gasket for an avionics tray comprises an annular flexible body 1 having a substantially flat surface 2 extending around the outermost area of the gasket and an annular sealing surface 5 of convex contour located above and extending parallel to the inner edge of said substantially flat surface 2. An annular channel 6 separates the sealing surface 5 from said substantially flat surface 2, the annular channel 6 extending downwardly to a level below that of the flat surface 2. A downwardly and inwardly inclined wall portion extends from the annular sealing surface 5 to a groove 8 which extends around the inward facing surface of the gasket body 1 and is located below the level of the substantially flat surface 2. The groove 8 serves, in use, to retain a metering plate. If it is desired to change from one metering plate to another, all that is required is to remove the instrument mounted directly above the gasket, after which the existing plate can be snapped out of the groove, and the replacement metering plate then snapped into the groove. <IMAGE>

Title: Vices
IPC: B25B1/12
Filed: 1980-11-03
Abstract: A vice has a main screw (18) which produces a simple translational movement of a movable vice jaw (16) towards or away from a fixed vice jaw (12). In additional to this translational movement, one of the vice jaws (16) is shiftable angularly about a vertical axis (52); this movement is produced by a second clamping screw (20), so that the vice can be adjusted to avoid line or point contact between the vice jaws and the workpiece. Preferably, a third clamping screw (22) which produces a controlled angular adjustment of one of the vice jaws (16) about a horizontal axis. This adjustment also may help in achieving better contact between vice jaws and workpiece. The movable jaw may be carried on a tube (30) in which operates the main screw (18). The tube has openings accepting a projection (32) in a body carrying the fixed jaw for stepwise translational adjustment of the jaw (16). The tube and movable jaw may be removed from the body and attached to a sash cramp. <IMAGE>

Filed: 1982-02-23
Abstract: Method and apparatus for measuring blood pressure using a first transducer 2 comprising a pick-up coil on a self adhesive mounting, which in use is attached to the patient's chest. A second transducer 4 is attached to the patient's wrist. The transducer 2 is connected to the input of a trigger circuit 6, so that when a voltage peak of a predetermined size appears in the pick-up coil 2, the trigger circuit produces an output pulse which is applied to the reset input of a counter 8. The output signal from the second transducer 4 is applied to a second trigger circuit 10, whose output is in turn applied to the "set" input of a bistable 12, whose "reset" line is connected to the output of the trigger circuit 6. A clock pulse generator 14 supplies clock pulses to the input of the counter 8, which are gated by the output from the bistable 12 by means of AND gate 16. The output from the counter 8 is supplied to the input of a calculator circuit 18, which is in turn connected to the input of a display 20. <IMAGE>

Title: A method of and apparatus for welding together metal components
IPC: B23K26/08
Filed: 1982-05-10
Abstract: In a method of welding together metal components (A, B) of high restraint geometry (as defined in the Specification) the components are urged into abutment and a high energy density weld is effected at a location in said abutment by means such as electron beam, plasma arc, plasma jet or, as shown, a focussed laser beam (L). In order to compensate for the high restraint geometry of the components which prevents them from deformation such as to accommodate welding stresses, an additional force (J) is applied, for example by a roller (K), to urge the components together adjacent to the position at which the weld is effected. The method is advantageously employed to form a continuous elongate weld between a platform and web of a brake shoe. <IMAGE>

Title: Boring in the ground
Inventor: SCHREIBER WOLFGANG
IPC: E21B47/022
Filed: 1982-11-10
Abstract: A method for determining the position and location of a device for producing a connecting boring in the ground between two vertical bores. This cross borer device having a front part 2 and rear part 3 moving in alternation, the operation of determining the position and location is carried out by incrementally adding together the vectors of movement of the cross borer. For this purpose the coordinate axes of the rear part 3 are determined by means of a starting part remaining in the starting hole of the crossbore. After the front part 2 bearing a boring head has moved forward the coordinate axes of the front part 2 are determined in relation to the rear part 3. The rear part 3 is then moved up into position, the situation and location being determined relative to the front part 2 and used in relation to the latter as a reference coordinate. <IMAGE>

Title: Process for the hybridization of cotton
Inventor: OLVEY JAMES
IPC: A01N43/80
Filed: 1983-01-04
Abstract: Methods are disclosed for rendering cotton plants male sterile through application of isothiazole plant growth regulators without causing substantial female sterility or loss of reproductive vigor. Processes for effecting the hybridization of cotton employing monitoring of the degree of burning of cotton bracts are presented. More particularly, male sterility is attained by the application of potassium 3,4- dichloroisothiazole-5-carboxylate to cotton plants in an amount sufficient to cause finger burning of the bracts without causing excess burning thereof. Hybridization is attained by exposing male sterile plants in accordance with the foregoing processes to pollen from plants of differing varieties of cotton.
