Title: Means for indicating or measuring an axial displacement of a rotary shaft
Inventor: HIMS HERBERT EDWIN CHARLES
IPC: F01D21/04
Filed: 1961-03-07
Abstract: 947,791. Turbines. BRITISH SHIP RESEARCH ASSOCIATION. Jan. 16, 1962 [March 7, 1961], No. 8307/61. Heading FIT. Means for indicating a pre-determined axial displacement of a rotary shaft, for example a turbine rotor shaft, comprises a pair of electrical contacts which are adapted to be closed upon axial displacement of the shaft, the contacts being movably supported so that the limits of the pre-determined axial displacement of the rotary shaft can be adjusted whilst the shaft is rotating. In Fig. 1 the turbine rotor shaft I is formed with a flange 2 on which is mounted a ring member 3. A bell-crank lever 5 is pivotally mounted at 6 and carries at one end a pair of contacts 4 which co-operate with the adjacent surface of the ring member 3, the contacts 4 being connected in a circuit comprising a source of current 14 and indicator lamp 15. A test switch 15a is also included. The bell-crank lever is biased by a spring 8 so as to urge the contacts 4 towards the ring member 3, the desired clearance between the contacts and ring member being set by means of a set screw 10, the distance between the reference surfaces 11, 12 being a measure of the clearance between the contacts 4 and ring member 3. In a further arrangement, the contacts 4 are mounted on a plate member which co-operates with the end face of the rotor shaft, the plate member being supported on a spindle which has means for securing the contacts on the plate member at the desired axial spacing from the end surface of the rotor shaft. The arrangement shown in Fig. 4 provides a means for indicating the relative axial displacement between a turbine rotor shaft and casing, the arrangement comprising a bell-crank lever 25, pivotally mounted at 26 and carrying a pair of electrical contacts 24 adapted to co-operate with the axially-facing surface of a flange 23 on the rotor shaft. The bell-crank lever is urged in a clockwise direction by means of a spring 28. A micrometer device 29 is associated with the bell-crank lever so that by adjusting the position of the micrometer spindle, the distance from a datum that the contacts have to be moved to touch the annular surface on the rotor shaft may be accurately determined.

Title: Improvements in or relating to vehicles for the conveyance and manipulation of frames, cases and other heavy objects
IPC: B60P1/64
Filed: 1935-03-18
Abstract: 440,233. Handling removable vehicle bodies; jacking-apparatus. MAQUARD, R. L. M., 183, Avenue de Clichy, Paris. March 18, 1935, No. 8431. Convention date, March 17, 1934. [Classes 78 (iii) and 78 (iv)] [See also Group XXXII] A vehicle is fitted with a loading or unloading platform which can be raised and lowered on jacks and also carries two roller-receiving paths at right angles, so that a removable loadcontainer can be handled from either side or at the rear. In the form shown the platform of a tractor or trailer can either be raised bodily, as shown in Fig. 1, or tilted about an horizontal axis as shown in Fig. 3. The tilting axis 5 forms the head of two rear hydraulic jacks, which work in conjunction with one or a pair of front jacks 9. The jack 9, as shown, is arranged horizontally and lifts the platform through levers 17, 18. A distributing-valve allows fluid to be admitted to any one or to all of the jacks. When the platform is raised bodily by working all the jacks simultaneously, pegs placed in holes 36 lock it at any height, but when tilted by working the front jack only, a hinged front support 38 is turned up under it, and a ramp 28 is slid on rollers from a nested position under it to a ground-engaging position. The platform carries a double set of rails or guides at right angles to one another, so that a load carrier 44 with turntable wheels can be hauled laterally or longitudinally on to the platform by the winch 64. When in running position, the load-carrier is centralized by the raising of sliding pegs on the platform into engagement with recesses in its base, and after being raised from the rails by small screw jacks it is secured by rope or wire lashings carried on the platform. In order to prevent an unequally-distributed load from causing unequal lifting of the rear jacks, they are connected to the supply pipe 22 through an equalizing-device as shown in Fig. 12. Raising of one end of the axle 5 more than the other, tightens one cord 76 and slackens the other. One lever 72 is thus rotated forcibly, moving the pistons 69 axially and increasing the area of the entrance into the feed-pipe 68 of the over-loaded jack, and diminishing the area of entrance to the underloaded one.

Title: Photolithographic production of resistance elements
IPC: H01L21/70
Filed: 1976-03-03
Abstract: In the course of photolithographic patterning of resistor tracks in hybrid circuits (thin-film technology), a substrate is obtained as an intermediate product, which is completely covered with a resistive film on which, in addition, there are conductor tracks which were selectively applied by means of physical or electrochemical processes; in order to pattern the resistor tracks, the substrate is covered with strips of a photo-sensitive resist which cover the conductor tracks at least in part, after which the superfluous resistive material is removed with a chemical etchant and the photoresist after etching is removed again. Prior to the etching of the resistive film, the photoresist is exposed by means of a mask, and the unexposed parts are removed, so that during etching of the resistive film the hybrid circuit is covered by means of the photosensitive resist in such a way that only the resistive material comes into contact with the etching solution. <IMAGE>

Title: Improvements in or relating to control valve devices
Inventor: ORLOFF GEORGE
IPC: F15B13/043
Filed: 1952-04-03
Abstract: 730,965. Valves under control of auxiliary pilot valves. BRITISH MESSIER, Ltd. April 2, 1953 [April 3, 1952], No. 8595/52. Class 135. A control valve in a fluid-pressure circuit is moved in both directions by two fluid-pressure actuators, there being a throttled supply and a throttled exhaust passage to and from each of the actuators, and the valve is caused to move by varying the relative degree of such throttling under electromagnetic control. Pressure liquid from a supply 15 is applied to one end 14 of a jack in order to load it, and the liquid also flows past restrictions 34, 35 into chambers 32, 33 where it can act on the equal end faces of a piston valve 20. The central land of the valve controls a port 24 leading to the other end 17 of the jack so that, when the valve 20 moves, it either places the end 17 in communication with the pressure supply through a port 23 or exhausts the end 17 to a line 29 through a port 25. The pressure liquid in the chambers 32, 33 can flow out past restrictions 38, 39 to opposed nozzles 40, 41, and the discharge areas of the nozzles are differentially controlled by a ball 50 carried by the armature of a polarized electromagnet 45. If, for example, the electromagnet is energized to cause the ball 50 to obturate nozzle 41, a back pressure will build up in chamber 33 and valve 20 will move to the left to place the end 17 of the jack in communication with the exhaust, and, owing to the differential areas of the faces of the jack piston, the latter will move to the right. In moving to the left, valve 20 will close off restricted passage 38 and pressure will also build up in chamber 32. If an electric feed-back is taken to polarized electromagnet 45, the speed of the jack will be a function of the current flowing in the electromagnet.

Abstract: 887,528. Circuits using bi-stable magnetic cores. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Sept. 25, 1959 [March 13, 1959], No. 8786/59. Class 40 (9). Signals on code wires, such as C, D, E, F and G, are registered on pairs of cores, one core of each pair being connected in a first column and the other core of each pair being in a second column, the first column being set to 0 and the second column being set to 1 so that a signal on a code wire reverses both and read-out produces output from the first column corresponding to marks while the second column gives output corresponding to spaces. As shown, two registers A and B are used alternately to register code markings. There may be an output winding on each core and the register may be driven by a common read-out winding between terminals A1, or each column may have a common output winding and each pair of cores may be read-out in sequence. After read-out of a register all the cores in both columns are at 0 and the second column is set to 1 by the winding between terminals A2 or B2. During a period in which code signals are received a register is made accessible by a two-thirds-write pulse on windings common to both columns between terminals A4 or B4, this signal being opposed by a one-third-bias current in the common windings between terminals A3 or B3. The resultant one-third-write pulse provides temperature stability. Code signals are of a two-thirdswrite strength and will not affect a register until made accessible over terminals A3, and A4 or B3 and B4. Bias is a constant current taken from the collector emitter path of a transistor. The output windings of a register may be gated by the read-out pulse.
