Title: Lifting jack apparatus for vehicles
IPC: B60S9/12
Filed: 1933-02-13
Abstract: 402,625. Hydraulic jacks for motor vehicles. LEBEL, L., Weedon, Quebec, Canada, and ROSENTHAL, J., Times Building, 42nd Street, New York, U.S.A. Feb. 13, 1933, No. 4392. Convention date, Feb. 13, 1932. [Class 79 (iii).] In lifting-jacks for automobiles and other vehicles of the type in which hydraulic jacks are mounted adjacent each wheel, there is employed a fluid distributor between the reservoir and the jacks, conduits from reservoir to distributor and back with valve control a valve control of fluid to the jacks and locking means to prevent unauthorized operation. The essential features of the invention reside (1) in the provision of a switch for controlling the electric starter motor of the engine which serves also for actuating the pump, and (2) in adapting the motor to actuate the pump when the motor rotates in the opposite direction to that for starting the engine. The switch controls the operation of a pump for forcing liquid from the reservoir to the distributor. As shown in Fig. 2 a lock controlled element 46 is, by the operation of a key inserted at 47, turned to close a valve 45 Fig. 3 connecting the distributor 38 with the fluid reservoir 72, and in addition to operate a contact 51. The circuit is closed through an arm 50 contact 51 brackets 53, 55 and contact plate 56 and by depression of one of a series of rods 44 engaging a corresponding contact plate 56, as indicated in Fig. 7. Depression of the rod also operates a ball valve 42 to open connection through a corresponding pipe 109 leading from the distributor to the particular jack to be operated. An electro magnetic switch 61 is also energised to cause a small current to flow through a switch 71 on the top of a float chamber or reservoir 72. Simultaneously with the above action the starter motor is actuated to pump fluid from the reservoir into the manifold 38 and to the particular jack to be extended. When sufficient liquid has been extracted from the reservoir the float thereof drops and breaks the circuit of the switch 71.

Title: Positioning mechanisms
IPC: G05B19/44
Filed: 1971-02-11
Abstract: 1395701 Gauging and setting J T RILEY 10 May 1972 [11 Feb 1971] 4441/71 Heading B3B A positioning mechanism comprises a movable member, e.g. a work slide 10 or 10a, fluid operated means for moving the member, and control means for the fluid operated means the control means comprising a control member, e.g. a card 28, having edges provided thereon, e.g. by one or more apertures, sensing means 25, 27 movable in response to movement of the movable member and arranged to sense the edge of an aperture in said card 28 and provide a control signal for the fluid operated means to stop the movement of the movable member in a position corresponding to the sensed position of the aperture edge, and means for moving the control member transverse to the movement of the sensing means to effect a subsequent positioning movement of the movable member. In one embodiment, for each direction of movement X, Y a pair of rods 22 are connected to the movable member by an inextensible cable or wire 21. Each rod carries a sensor 25, 27 arranged oppositely of the card 28 and an air jet passes from sensor 25 to sensor 27 when an aperture is aligned therewith to produce a control signal 27. The movement of the member is stopped with an edge of an aperture obstructing the air jet, movement either way producing a correcting movement by a feed back control function. The amount of clearance, or the amount of obstruction, for the air jet effects the strength of signal 27 to produce an analogue signal 17, 18 to an hydraulic drive means 11 so that movement of the member 10, 10a is slowed down as it approaches its stop position. A plunger or ridge having a conical or V-shape positively locates the member. In a further embodiment (Figs. 6-12, not shown) for each direction of movement two pairs of sensors are used, one pair initiating a slowing down movement, the second pair stopping the movement. A further set of stationary sensors are used to pre-set the direction of the slowing down and stopping functions.

Title: Device for Indicating the Direction of Incident Plane Sound Waves
IPC: G01S1/72
Filed: 1968-01-30
Abstract: 1,199,122. Direction-finding. FRIED. KRUPP G.m.b.H. 30 Jan., 1968 [31 Jan., 1967], No. 4783/68. Heading H4D. A device for indicating the incoming direction of plane sound-waves comprises a receiving transducer array having two directional characteristics angularly offset from one another, and two array output signal voltages associated respectively with the two characteristics are used as the X and Y deflection voltages of a cathode-ray tube. In the Fig. 1 embodiment a linear array of transducers 1 to 4 linked by delay network 5 has two directional characteristics at equal and opposite inclinations to the normal to the array. Output voltages U5, U6 developed in response to an incoming wave at an angle γ to the normal are rectified at 6, 7. Modulators 8, 9 provide carrier-wave voltages U9, U10, proportional to the rectified voltages, which control the orthogonal beam deflections of cathode-ray tube 11 to give a radial trace at an angle representing wave direction. In the Fig. 4 embodiment the outputs of transducer pairs 12, 14 and 13, 15 feed difference measuring units 17, 18 whose outputs U17, U18 correspond to signals from two dipoles having orthogonal figure-eight directional characteristics. U17 and U18 are fed via amplifiers 19, 20 to multipliers 21, 22 where they are multiplied by the 90 degrees phase-shifted output U19 of an omnidirectional transducer 16 to give product signals U20, U21. The multiplication step provides a "correlation" of the transducer outputs and so discriminates against random noises reaching the transducer array. The product signals are integrated at 24, 25 to provide D.C. signals U22, U23 which are directly compared by a ratiometer and are fed via choppers 27, 28 as X and Y deflection signals to cathode-ray tube 26 to display a radial line Z. Transducer 16 may be dispensed with if the sum voltage of all four transducers 12-15 is formed: a suitable transducer array then comprises a magnetostrictive ring with four toroidal windings each extending over 180 degrees and offset by 90 degrees from each other. For incoming waves with a periodic component (e.g. propellor sounds from ships), delay units with a delay equal to an integral multiple of the periodicity may be used in the U19 (or U17 and U18) signal channels to improve the signal-to-noise ratio. Further discrimination against noise may be provided by band-pass filters.

Abstract: 1496631 Pressing vehicle mats on a turntable TEXTILFORM SA 6 Feb 1976 [17 Feb 1975] 04799/76 Heading B5A Vehicle mats are given a contour in apparatus comprising a plurality of operator controlled presses mounted on a turntable that rotates to move the presses in succession through mat supply and removal stations, the turntable being capable of carrying the operators. As described, six different or identical presses, 4 (Fig. 3), are mounted on the turntable 1 having a flat, horizontal surface level or stepped from the factory floor 2. Each press comprises a female die 8 having a heating or cooling liquid jacket 9, and mounted on a framework 7. An upper male die 13 is pivoted about an axis 14 by an actuator 15. An unshaped mat is held at its edges during press closure manually, or by smooth-faced gripping jaws 21, 22 that are closed by actuators 24 pivoting the jaws 22, and allow slippage of the mat therebetween during closure. Alternatively, both jaws 21, 22 move during closure towards the press, with no such slippage, as jaw 22 is pivoted by actuators 24, while both jaws 21, 22 are moved on a lever 27 (Fig. 5) against an hydraulic damping cylinder 30 (or a helical compression spring, or levers and a tension spring). The jaws can include cooperating spikes 25 and holes 26 for clamping the mat. Other gripping jaws can comprise one or more flexible sets of chains 31 (Figs. 6 and 8). Each set includes parallel chains 31 movable together and apart by actuators 36, and tensioned by springs 33. The chains engage the mat by jaws 32c (Fig. 8), or by spikes and apertures 32 (Fig. 6). In an alternative form, each chain set comprises a single chain supporting mat-engaging spikes. Undercut mats can be produced using a male die 13 (Fig. 10) including a subsidiary die 38 movable after die closure for moulding the undercut. Heating or cooling fluid and fluid for the actuators are supplied by a distributer (see Fig. 11, not shown) mounted above the turntable. Operation.-Slab or sheet-like unshaped mats of felt, boudÚ or tufted carpets are provided on a nylon or polyester backing with acoustic and/or thermally insulating layers, or with a polyethylene backing film applied with melted polyethylene powder adhesive. The mats are cut roughly to shape, and heated to 80-90‹ C. in a manually operated infra-red heater adjacent the press turntable. As the turntable is rotated intermittently by an adjacent operator control, a heated mat is placed one in each of successive presses reaching the heater. After pressing to their contour by the presses, which are controlled by operators carried by the turntable, the mats are successively trimmed, and holes melted by hot tools pushed through the closed press dies. These tools are heated in a furnace adjacent one of the stopping places of each press. Cooling liquid is passed through the female dies, and each press unloaded when it stops adjacent an unloading station.

Abstract: 1,015,332. Measuring high voltage. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Feb. 7,1963 [Feb. 9, 1962], No. 5028/63. Heading G1U. An apparatus for use in measuring or controlling a high D.C. voltage comprises a capacitor having one plate 1 connected to the high voltage and the other plate 2 connected to a semi-conductor circuit 11 which allows charges to flow either to earth or to an integrator 13, according to their polarities, this flow being controlled periodically by the movement at a frequency f of an earthed conductive screen 5a between the capacitor plates. The integrator receives, at the same frequency, standard charges of the opposite polarity, and the output of the integrator is connected after suitable amplification to a measuring or control circuit 18. The circuit for supplying standard charges to the integrator may consist of an electro mechanical switch 16 operated at the frequency of the rotating screen 5a which alternately allows a capacitor 15 to charge from a source 14 and discharge into the integrator 13. The action of the rotating screen 5a is to completely charge and discharge the capacitor 1 during each rotation, so that a charge proportional to the voltage V to be measured is passed to the integrator 13. The output of the integrator is passed to a zero detector 18, and the voltage E of the source 14 adjusted until zero output is obtained. A simple relation then exists between the voltages E and V, depending on the capacitors 2 and 15. For control purposes E is kept constant and the circuit 18 used to adjust the high voltage V. An alternative embodiment utilizing a thyratron instead of an electromechanical switch 16 is described (Fig. 3 not shown).

Abstract: 555,824. Aircraft stalling speed indicators FERRANTI, Ltd., and CLUDERAY, E. S. April 19, 1941, No. 5081. [Class 4] For indicating the variations of the stalling speed of an aeroplane a spring-supported weight responsive to accelerations parallel to the normal axis of the aircraft is connected by linkwork, described below, and gearing to a pointer moving over a scale graduated to show air speeds. The instrument may be combined with an air speed indicator having a pointer moving over the same scale and an additional scale may be provided to indicate the values of the accelerations parallel to the normal axis. A weight 1 mounted on a spring 2 is connected by a link 5 to an arm 6 on a spindle 8 carrying a toothed quadrant 9 gearing with a pinion 10 on a sleeve carrying a pointer 12 moving over a scale, not shown. The pointer 12 is frictionally mounted so that it can be initially set to the normal stalling speed of the aeroplane. The initial inclination of the arm 6 to a perpendicular from the spindle 8 to the link 5 is greater than when the weight is subject to additional acceleration so that the square root law of response of the weight 1 to accelerations is balanced by the sine law of the arm 6 to give a substantially linear displacement over the dial. The arm 6 is connected by a link 17 to an air dash-pot 15, 16. A disc 20 marked in multiples of the acceleration due to gravity moves behind a window in the dial. A second pointer 23 is geared to a capsule 33 connected to a pitot tube to indicate actual air speeds on the same scale. An instrument without the second pointer 23 also is described. Specification 539,787 is referred to.
