Filed: 1936-02-24
Abstract: 466,052. Spring hinges. SALTER & CO., Ltd., G., and BACHE, R. S. Feb. 24, 1936, No. 5435. [Class 65 (ii)] A spring hinge for doors and the like, in which the spring is automatically rendered inoperative after a certain degree of opening so that the door will remain fully open without holding, the spring being automatically brought into action again when the closing movement of the door is started by hand, comprises a pair of leaves 1, 2 with outstanding lugs connected by a hinge pin 5 about which is placed a torsion spring 6 having its upper end 7 pressing on the leaf 2 and its lower end 8 pressing on leaf 1. The edge of the lower lug 2b of leaf 2 is turned up to form an inclined catch part 9 over which the end 8 of the spring will ride after a certain degree of opening, the end 8 then being held behind the part 9 and the spring pressure being consequently taken off the leaf 1. The edge of the lower lug 1b of leaf 1 is also turned up to form a cam 11, and when the leaves are moved towards the closing position this cam rides under the end 8 of the spring, pushing the latter up until it clears the catch part 9 and resumes its operative position against the leaf 1.

Abstract: 461,390. Hand trucks. BEAUFOUR, R. E. Feb. 24, 1936, No. 5529. Convention date, Feb. 25, 1935. [Class 108 (i)] [Also in Group XIV] An adjustable surgical bed comprising a frame 1, Fig. 3, and a mattress-supporting upper frame 10 is used in conjunction with a transporting chassis, shown in Figs. 8 and 9 by means of which the upper frame 10 may be lifted from the frame 1 and transported with the patient lying thereon. The frame 1, Fig. 3, is provided with castors 2 and movable feet 3, and with blocks 6 mounted to pivot on two horizontal axes at right angles. A lifting jack 7 is mounted in the centre of the frame, by means of which the mattress frame 10 can be tilted about either side edge or either end by appropriate manipulation of the blocks 6. The transporting chassis, Figs 8 and 9, comprises a U-shaped frame 24 with bracing members 26, mounted on three wheels 28, 30, and provided with three lifting jacks 34, 35, preferably hydraulic, which can be operated either together, singly or in any desired combination by means of mechanism such as a pump 36. The jacks are provided with swivelling heads adapted to engage sockets 40, Fig. 3 and pins 41, on the mattress supporting frame 10. The transporting chassis can thus be wheeled into position around the bed frame and the frame 10 engaged by the jacks, lifted off the frame 1, and inclined if desired. A frame 23, Fig. 14, carrying transverse straps upon which the patient may be lifted, is also provided, and normally engages guides 14 at the head of the frame 10. This frame 23 is also provided with sockets and pins which can be engaged by the heads of the jacks on the transporting chassis, so that it can be lifted as shown relatively to the mattress frame 10 ; or lifted and transported with the patient thereon.

Title: Improvements in electric pulse generators
IPC: H03K3/55
Filed: 1944-03-30
Abstract: 585,359. Pulse generating circuits. WESTERN ELECTRIC CO., Inc. March 30, 1944, No. 5936. Convention date, Oct. 1, 1942. [Class 40 (v)] In a pulse-generating circuit, upon the flow of current through an inductor being interrupted, the energy in the inductor is transferred to a condenser which is suddenly discharged when the transfer of energy is complete, to generate a pulse in the load circuit. Upon the output of the square wave generator 23 going positive, valve 19 conducts causing current to flow through inductor 18. When the output of generator 23 reverses, the valve 19 is cut off, but current continues to flow in inductor 18 due to its self-inductance, thereby charging condenser 20 to a high positive voltage, the opposite plate being tied to earth through diode 26. The output of generator 23 is fed through delay circuit 24 so that gas-filled valve 21 is rendered conducting as the voltage on condenser 20 reaches its peak value, whereupon the condenser discharges through the magnetron 11 and valve 21. To avoid the accurate timing of firing of the valve 21, the valve is replaced by a saturable inductor, Fig. 5 (not shown), having high permeability at low flux density but easily saturated, thus presenting a high impedance at low current following rapidly with increase in current. A bias winding on the inductor fed from D.C. supply may be employed to adjust the point at which the impedance falls to a low value. To improve the pulse shape, Fig. 7 (not shown), the diode 26 may be shunted by a coil and given a small positive bias. U.S.A Specification 2,063,342 is referred to.

Abstract: 1,158,053. Upsetting. MASCHINENFABRIK HASENCLEVER A.G. 8 Feb., 1967 [10 Feb., 1966], No. 5955/67. Heading B3H. An electrical upsetting machine has spaced anvil and guide electrodes 2, 3, a first die 1 in which the rod-shaped workpiece 4 is upset, and a second die 6 disposed at the mouth of the first die. The rod is upset by pressure applied by an hydraulic ram 5 and the anvil electrode 2 is arranged to retract during the first stage of the upsetting process, to form the portion 4a. Thereafter the anvil electrode is stopped, the second die 6 is placed in position and upsetting is continued to form the portion (4b), Fig. 3 (not shown). Both dies may be in split halves movable radially outwards. The upset portion formed in the second die may be of larger or smaller cross-section than the portion formed in the first die. In other embodiments, Figs. 6-8 (not shown) the second die is movable axially and has a spigot portion (6c) which fits within an enlarged bore of the first die. The guide electrode 3 may be connected to but insulated from the second die 6. During the first upsetting stage the second die may be removed and the guide electrode 3 placed adjacent the first die. During the second stage of the upsetting process, the second die 6 may be used as the guide electrode, Fig. 7 (not shown). To obtain sharp transitions in the upset workpiece, Fig. 9 (not shown), surges of upsetting pressure or current supply may be applied.

Filed: 1948-02-27
Abstract: 669,634. Radio receiving circuits. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948 [Aug. 30, 1945], No. 5960/48. Classes 40 (v) and 40 (vi). A noise suppression circuit in a radio receiver comprises a first rectifier in series with a load impedance, a second rectifier in series with a load impedance of larger value, and connected in parallel opposition to the first rectifier and biased so that it is operative only for signals exceeding a predetermined amplitude, the input signals being impressed equally across the first and second rectifier circuits and the outputs across the two load impedances being combined. In the Figure the output from an intermediate frequency amplifier I.F. is applied to diode demodulators 10 and 38, which are connected in opposition. Diode 38 is biased by means of a source of potential - E so that it responds only to signals above a certain amplitude. The load resistance of diode 38 comprises resistances 28 and 24, while that of diode 10 consists only of resistance 24, so that diode 38 is more responsive than diode 10. The arrangement is then such that the normal signal output may be reduced and possibly suppressed entirely during noise impulses. The demodulated output is applied through a selected time constant circuit to video amplifier stage 30.
