Filed: 1920-03-26
Abstract: 164,190. Calthrop, E. R. March 26, 1920. Parachutes. - T h e positive opening of the mouth of a parachute is ensured by the formation of a plurality of pockets 8 arranged round its periphery and normally retained by attaching the peripheral webbing 2 to a seam 3 by resilient or rupturable members 6. The resilient members may be of rubber encased in sleeves 9. Two parallel resilient members may be used for each pocket and they may be attached to the junctions of the seams 3, 4. In a further modification, the resilient members are arranged horizontally and the sleeve 9 is then of concertina construction. When the load is released, the resilient members will contract and assist in expelling the high pressure air within the parachute body.

Title: Control system for lifts
IPC: B66B1/16
Filed: 1960-03-15
Abstract: 926,701. Control of motors; controllers. INVENTIO A.G. March 15, 1960 [March 16, 1959], No. 9029/60. Class 38 (3). The termination of acceleration and the braking of a lift cage having a regulated travel prescribed by a nominal valve transmitter are initiated as a function of the speed and of the distance of the cage from the intended stopping point. The switching elements shown indicate a lift at the second stop and it is proposed to move to the third stop. Floor relay contacts 5.3 and 8.3 are therefore closed and the cathodes of thyratrons 16 and 17 receive a positive potential by way of the contact 5.3 and a sliding contact 4.3 scanning a non-linear potentiometer 3 providing a voltage source representative of the position of the lift. A locking relay 9 is excited by way of a collector shoe 6, a sliding contact 7.3 and the relay contact 8.3 which relay switches in the anode voltage for the thyratrons by means of its contact 9.1. The control grids 16.3, 17.3 of the thyratrons are connected to a sliding contact 1.3 which scans a potentiometer 1.2 providing a voltage source corresponding to the speed of the lift. When the lift ascends, a door contact 22 is closed and a control contactor 10 closes its contacts 10.2 causing a setting motor 1.1 to displace the contact 1.3 upwardly whereby the potential at the control grids 16.3, 17.3 becomes more positive; simultaneously the sliding contact 4.3 moves and the potential at the cathodes becomes more negative. When the two potentials have approached to a small difference determined by a potentiometer 20 thyratron 16 fires and a relay 14 is energized whereby contact 14.1 breaks the circuit of contactor 10 causing contacts 10.2 to open and setting motor 1.1 to stop. The acceleration of the lift is thus terminated and it continues at a constant speed. After a short distance the potential tapped by the contact 4.3 has been lowered and the thyratron 17 is caused to strike whereby relay 15 is energized, contact 15.1 closes to energize contactor 11 whose contact 11.2 switches on the setting motor 1.1 in accordance with the retardation of the lift the speed of which is thus reduced to the fine setting travelling speed.

Title: Improvements in or relating to pneumatic hammer-drills and other pneumatic tools
IPC: B25D9/16
Filed: 1919-04-10
Abstract: 140,039. Soc. Belge d'Outillage Pneumatique (Ateliers Rorive). March 12, 1919, [Convention date]. Addition to 125,954. Percussive hand tools.-The automatic stop device described in the parent Specification is modified so that when the working tool moves forward owing to lack of resistance thereto, the exhausts from both ends of the cylinder are closed without affecting the inlets thereto. The piston is then held stationarv between two bodies of compressed air. In the form shown in Fig. 1, air from the inlet 0 flows past the valve N and through ports Q, R, A to raise the piston C; when the piston closes the exhaust port F, cushioned fluid lifts the valve N and fluid flows through port H to move the piston downwards, the valve being again reversed by cushioned fluid when the piston passes the exhaust ports G. When the tool K advances owing to lack of resistance, a sleeve I is also advanced by fluid acting on its rear end or on a forward shoulder M and closes the exhaust ports F, G, the inlet port A remaining open to the cylinder through elongated apertures D' in the sleeve. In a modification, the sleeve moves in an annular recess formed within the walls of the cylinder and directly open to the fluid inlet O. In the form shown in Fig. 3, the exhaust ports F, G are opened to the atmosphere through an annular groove U in a sleeve T and ports F<1>, G<1>; when the tool K advances, the sleeve T also advances under the pressure of the fluid or the blows of the piston and communication is interrupted between the ports F. F' and G, G' respectively. The ports F', G' may be deflected to open at any part of the cylinder. In a modification, the sleeve T is dispensed with, the groove U being formed in the shank of the tool K.

Filed: 1976-03-08
Abstract: 1534548 Signal rectification circuits FERRANTI Ltd 8 March 1976 [6 March 1975] 9251/75 Heading H3T A full-wave rectification circuit comprises a first amplifier 10 having a non-inverting input terminal 34 for receiving the signal, an output terminal coupled to the output of the circuit 30 via an asymmetric conductor 18, and an inverting input terminal receiving negative feedback via an oppositely poled asymmetric conductor 44 and a second amplifier 12 having an inverting input terminal 52 which is fed from a potentiometer 46, 48 connected as shown, and an output terminal coupled to the output 30 via an asymmetric conductor 20, 46 providing a sole feedback path for amplifier 12. When the signal goes positive diode 18 conducts, 20 and 44 are reverse biased, and a positive output appears at 30; when the signal goes negative 18 is off but 44 provides a low impedance feedback path to amplifier 10 which thus provides at node 38 a voltage substantially equal to the input signal to be fed to amplifier 12, the gain of which is proportional to the ratio of resistors 46 and 48. As amplifier 12 is arranged to invert the signal applied to it a further positive output appears at 30, so that full-wave rectification results. Unity gain is obtained if the resistors 46 and 48 are equal, and increased gain is obtainable with the optional resistor 60.

Title: Improvements relating to time limit overload electric relays
IPC: H01H71/44
Filed: 1919-04-11
Abstract: 139,660. Brooks, R., and Metropolitan- Vickers Electrical Co. April 11, 1919. Mercury switches; time-limit devices; electromagnetic switches.-In a time-limit overload relay, the operating-coil acts upon a core to which is attached a bucket having an orifice in the bottom and normally immersed in mercury contained in a reservoir, the circuit being completed through the mercury. In the arrangement shown in Fig. 3, the floating core 2 moves within the housing oi the overload coil, and the housing and coil are adjustable in relation to the core, for current-setting purposes, within a tube 10, the parts being fixed, when adjusted, by a screw 14 engaging a slotted plate 16. The tube 10 is slidably adjustable within a tube 18 mounted on the insulating- cover of the mercury reservoir 6, similar fixing- means being employed. The second adjustment, which (by reason of the annular projection 12 on the extension 3 of the core which passes into the reservoir and carries a bucket 4 having an orifice 8) does not affect the first adjustment, determines the initial immersion of the bucket within the mercury. The relay circuit, which passes through the core and its extension and through the mercury, is broken when, on overload, the bucket has been first lifted, together with the mercury within it, clear of the mercury in the reservoir, and thereafter the stream of mercury from the bucket to the reservoir has discontinued. With the heaviest overload, this will take a certain time, dependent on the size of the orifice 8. With smaller overloads, further time (varying inversely with the overload) will be taken up in lifting the bucket. This time element is dependent upon the initial adjustment of the position of the bucket within the mercury and upon the size of the orifice. In a modification, Fig. 4, the relay circuit is made instead of broken, with the same time-element features as already described. With the heaviest overload, the bucket is raised immediately and prepares the relay circuit at the contact 23. The circuit is incomplete, however, as the withdrawal of the bucketful of mercury from the reservoir leaves the dipping contact 22 clear of the surface of the mercury, and this contact is made only when the mercury has passed through the orifice in the bucket to raise the mercury level in the reservoir. With lesser overloads, the arrangement acts with the inverse time.element feature, as before.
