IPC: E04F21/22
Filed: 1945-06-05
Abstract: 593,166. Floor cramps. SAYER, E. C., and FRIDAY, F. W. June 5, 1945, No. 14194. [Class 61 (ii)] A hydraulically-operated floor cramp consists of a body 1 welded to which is a fixed joist jaw 2 and a movable jaw 3 secured to a piston 8 which slides in the cylinder 12 of the body 1. The cylinder is connected by the passage 16 to the pressure chamber 17. By operating the screw plunger 23 in the pressure chamber, the operating fluid may be forced into the cylinder 12 and the opposing joist jaws drawn together. A return spring 14 brings the jaws out of the clamping position on unscrewing the plunger 23. At right angles to the cylinder 12 a second cylinder 18 extends from the body 1, Fig. 3, containing a ram 19 which is adapted to operate against a floorboard. The inner end of the cylinder is connected to the pressure chamber 17 by the passage 21. A return spring 20 brings the ram into inoperative position on unscrewing the plunger 23.

Title: Improvements in or relating to relays for amplifying small forces
IPC: G01D5/42
Filed: 1942-10-09
Abstract: 562,645. Relays for amplifying movements to indicating apparatus. NEGRETTI, H. N., NEGRETTI, P. E., and GREENING. E. F. Oct. 9, 1942, No. 14217. [Class 118 (ii)] [Also in Groups I, XVIII, XIX, XX. and XXXVI] A relay for amplifying small forces comprises a pivoted lever to be loaded with the small force and adapted to transmit the load to a pallet against the pressure of a fluid from a nozzle, affording a small escape, in a tapping from a fluid pressure supply line, leading to means for directly operating an indicator, recorder and/or an instrument of control, so that a small movement of the pallet due to change of loading varies the escape and causes the pressure in the supply line to build up or subside to a valve balancing at the nozzle the load transmitted to the pallet. As shown in Fig. 1, the invention is applied to the amplification of the difference between the external and internal pressures acting on a capsule 1, which may be of the type described in Specification 561,220, [Group XIX]. The boss of the capsule is connected to a lever 5 by a flexing strip 9 and by a compression spring 8 which prevents overloadiiig. Expansion of the capsule is limited by an adjustable stop 13. A bimetallic strip 15, adjustable lengthwise, is connected by a light compression spring 17 to one of several notches 18 in the lever 5, so as to compensate for temperature changes within the casing. The lever 5 is fulcrummed to a flexible diaphragm seal 6 and is acted on at its other end by a tension spring 19, finely adjustable, Fig. 2 (not shown). A dashpot 26 damps vibrations in the lever. A bearing block 27 is frictionally adjustable along the lever and bears on a strut 28 acting on a block 29 bearing a pallet 30 controlling the escape of pressure fluid from a nozzle 33, tapped off a pipe-line with a constriction, Figs. 2 and 3 (not shown), so that the pressure builds up or subsides quickly to control an indicator, recorder or controlling device. In Fig. 5, the force applied to the lever 5 is derived from a temperaturesensitive element connected to a Bourdon tube. In Fig. 6, humidity is measured by a hygroscopic element 47 through a light tension spring 48. Fig. 7 shows an indicating instrument operating the lever 5 through a spring 52, lever 5], and cam 50. The invention is applied to a weighing device in Fig. 8, and Fig. 9 shows an electrical meter in which a solenoid 57 is actuated by a coil 58. Specifications 226,137, [Class 106 (ii)], and 341,365, [Group XIX], also are referred to.

Title: Impedance-measuring device
IPC: G01R27/02
Filed: 1962-04-17
Abstract: 998, 827. Impedance measurement; determining physical dimensions and qualities. STEWARTWARNER CORPORATION. April 17, 1962 [June 14, 1961], No. 14829/62. Headings G1N and G1U. An impedance measuring device for e.g. a capacitance transducer comprises an oscillator having a resonant circuit shunted by the unknown impedance, and a frequency discriminator having a second resonant circuit tuned to the same frequency as the oscillator for an initial value of impedance; the two resonant circuits being coupled with a coefficient of coupling less than 1/Q where Q is the combined quality factor of the resonant circuits; the discriminator output being dependent on the deviation of the impedance from its initial value. In an automatic height control device for a gas cutting machine, a capacitative transducer 10 (Fig. 1) is spaced from workpiece 13 adjacent to torch 11 and determines the frequency of oscillator 12 initially tuned to a frequency determined by a preset height. The oscillator output energises a frequency discriminator 14 whose output dependent on height deviations excites bipolar relay 16 controlling reversible motor 22 which is geared to adjust the height of the transducer 10 and torch 11 above the workpiece and restore the oscillator frequency to its initial value. In Fig. 2 the capacitative transducer 10 is autotransformer coupled over coaxial line 54 across the tank circuit 30, 32 of adjustable initial frequency of Hartley type transistor oscillator 12, whose frequency varies in accordance with the transducer/workpiece displacement, and is loosely coupled to discriminator 14 over winding 70 whose centre tap is connected over line 74 to the tank circuit. Winding 70 is connected over slug tuned balanced bifilar windings 71 to the bases of transistors 78a, 78b as a resonant circuit with capacitor 72 at the initial frequency of oscillator 12, and the collectors are interconnected to the voltage supply 50 while the emitters are grounded over impedances 82a, 82b shunted by capacitors 86a, 86b so that a direct voltage appears across the impedances representing in polarity and sense the deviation of the oscillator signal for the discriminator tuned frequency (Fig. 3 not shown). Coupling between resonant circuits 26 and 73 is held between 0.3/Q and 0.5/Q where Q is the combined effective quality factor of the circuits. The output signal is zero when the oscillator frequency is identical with the discriminator frequency, and the impedances 82a, 82b may constitute the windings of the control relay 16. The apparatus is adaptable to measure absolute values of inductance or capacitance using a meter between the emitters of transistors 78a, 78b, and it is also usable as a capacitative aperture or thickness gauge. Specification 995, 421 is referred to.

Abstract: 572,395. Prepayment mechanism for meters. ENGLISH ELECTRIC CO., Ltd., TAGG, G. F., and WHITEHEAD, R. K. Sept. 10, 1943, No. 14903. [Class 27] Comprises meter mechanism adapted to take .a number of coins at once, wherein the first coin 6 inserted goes directly into a coin pocket 2 movable to-and-fro in the same plane as the coin shoot 1, the following coins being retained in the shoot above the pocket where they are held during the first movement of the pocket and also during the registration of credit, until the first coin has been discharged and the pocket returned to its original position when another coin is allowed to drop into the pocket. The pocket is reciprocated and the crediting shaft 9 is rotated by means of an electric motor 8, the circuit of which is closed either by the insertion of a coin or by manual closing of a switch 7. The shaft 9 reciprocates the pocket by means of a cam 10, and lever 12 in conjunction with a return spring 14. The pocket is just deep enough to accommodate the smallest diameter of coin used in the machine, the next coin in the shoot resting on the top of the coin in the pocket. As the pocket is moved inwards the next coin is kept back by a spring-loaded slide 3 and rides on the top 2a of the pocket. If a large coin is in the pocket, as shown, it projects above the pocket and as the pocket moves inwards the coin engages and lifts the slide 3 which allows this coin to pass but stops the one above, which then drops on to the top 2a of the pocket. The pocket moves inwards until arrested by a stop, the coin 6 being calipered by a coin-gauging member 16 which enters the pocket through a slot 2b, the coin then driving the member 16 and a. creditdetermining member secured thereto against a biassing force to a position dependent on the diameter of the coin. The coin-gauging and credit-registering mechanism may be as described in Specification 572,403. At the end of the crediting operation the shaft 9 actuates known means whereby the coin is discharged from the pocket into the till, the pressure on the coin of the inclined edge 16a of member 16 assisting such discharge, after which the pocket returns to its original position. Specification 449,673 also is referred to.

Title: Improvements in and relating to centrifugal fuses for projectiles
IPC: F42C15/22
Filed: 1925-06-09
Abstract: 235,244. Pantoflicek, B. June 9, 1924, [Convention date]. Projectile fuzes.-Relates to fuzes comprising centrifugal weights which move outwards during the fitght of the projectile and, when centrifugal force ceases on impact, are moved back by springs and release a spring striker. According to the invention, the firing movement of the weights is normally prevented by means of balls, which leave the safe position when the weights move out by centrifugal force, thereby permitting the subsequent firing movement on impact. In Fig. 1, the striker 6 has a flange 12 normally engaged by the forked end 7 of a centrifugal weight 3, which is guided in a slot 2 and by a tongue 8 in the fuze casing and is prevented from releasing the striker by balls 10 seated against shoulders 9 on the tongue 8. During flight, the centrifugal weight 3 moves out against a spring 11 and the balls 10 fall out of their locking position shown. On impact, centrifugal force ceases, and the weight 3 is returned by its spring 11 and, being no longer stopped by the balls 10, moves further back and brings a gap 5 in line with the striker, thereby releasing it. In a modification, centrifugal balls guided in straight grooves in a fixed part of the fuze move out and rotate a disc against a spring during flight; other centrifugal balls then unlock the disc; and on impact the disc is rotated back and beyond its original position and releases the striker. In a further modification, Fig. 5, a disc 27 carrying centrifugal weights 26 rotates about a transverse axis 33 during flight; a locking ball 29 then slips out through a slot 32; and on impact, a spring 34 rotates the disc back and beyond its original position, bringing a notch 28 in line with a spring bolt 36, which thereupon liberates balls 38, releasing the striker 39.
