Title: Mechanical amplifier
IPC: G05G19/00
Filed: 1968-01-19
Abstract: 1,204,771. Winch drives. BATTELLE DEVELOPMENT CORP. 19 Jan., 1968 [13 Feb., 1967], No. 2922/68. Heading B8B. [Also in Divisions F2 and G1] A winch drive torque amplifier comprises a rotatable cylinder 13, Fig. 1, around which are wrapped flexible elements 15, 17. The portions of the elements which emerge from the cylinder with the direction of rotation pass around an input pulley 19 while the portions which emerge from the cylinder against the direction of rotation pass around an output pulley. The pulleys may continuously rotate or may have restricted motion but in either case rotation of the pulley 19 in either direction tightens one of the elements about the cylinder to give a corresponding amplified rotation to the pulley 21. In an application for amplifying sound a diaphragm is connected to a pivoted lever connecting the input flexible element portions of a first pair of flexible elements and a similar pivoted lever connects the output portions of another pair of flexible elements and is connected to a diaphragm. The cylinder is stepped with three different diameter portions around each of which is wrapped a pair of flexible elements connected to pivoted levers forming amplifier stages, the lever forming the output of one stage being connected with the pivoted lever forming the input of the next stage. In another embodiment, Figs. 4 and 8, a finned amplifier drum 91 is driven by a motor 89 with a speed control 129 and has flexible elements 95, 97, wrapped therearound and passing about idler pulley 99 and output pulley 101 which is fast with pulley 105 drawing an instrument pen slider 107 with cord 109. An input is fed to a summing amplifier 115 connected to a fixed coil 163. The moving coil is rigid with a rod 167 pivotally connected to a rocker 169 pivoted at 173 and carrying drums 175, 177 over which the flexible elements 95, 97 pass. According to the input signal the moving coil rocks the rocker 169 to move one or other of the elements 95, 97 into engagement with the periphery of a rotatable control drum 127 which pulls one or other of the elements about the amplifier drum 91 to give an output rotation to pulley 101 which in turn moves the slider 107. The slider contacts a feedback slide wire 119 which feeds a signal to the amplifier 115 so that when the feedback and input are balanced in the amplifier 115 the slide is at the correct position and no current is supplied to the transducer, the rocker 169 thus returning to its neutral position.

Abstract: 683,524. Magnetrons. COMPAGNIE. GENERALE DE TELEGRAPHIE SANS FIL. Feb. 3, 1949 [Feb. 4, 1948; Feb. 6, 1948: Feb. 7, 1948; Feb. 11, 1948], Nos. 3044/49, 3045/49; 3046/49 and 3047/49. Class 39(i) A mutti-cavity magnetron has empty grooves formed in the anode block to connect neighbouring cavities to one another; the grooves are of such depth and width as to provide desired degree of coupling between the cavities. The tendency to self-oscillation may be reduced or eliminated, and the magnetron may be operated as a stable amplifier or as a wide-band oscillator. Conventional strapping may also be provided, or the anode segments may be shaped as described in Specification 666,689, to secure operation in the #-mode. As an amplifier, only two cavities may be provided in the anode block. Cavity B<SP>1</SP>, Fig. 12, is the input circuit, and cavity B<SP>2</SP> the output. For cascade amplification further cavities may be inserted between cavities B<SP>1</SP> and B<SP>2</SP>. As shown, Fig. 16, in a class C amplifier the cathode K is eccentric in the cathode space. The intense electric field in the region F prevents electronic back coupling between the input and output circuits, or a suitable magnetic or electrostatic field, or screens may be provided. In a wide frequency band amplifier the input circuit may consist of two cavities B1, B1<SP>1</SP>, Fig. 17, resonant on two adjacent frequencies, and the output circuit a similar pair of cavities B2, B2<SP>1</SP>. As an oscillator, cavities may be provided all round the anode block, and two of the cavities coupled to a tunable stabilizing and output external resonator of high Q. With an external resonator constituted by a wave guide, coupling may be directly to only one cavity through a glass member. Specification 663,625 also is referred to. The Specification as open to inspection under Sect. 91, comprises also the provision of coupling between the cavities through external circuits, such as including a coaxial line, a wave guide, a resonant cavity, or an auxiliary tunable magnetron, instead of, or as well as, through grooves in the anode block. Where grooves are provided their effects may be adjusted by inserting conducting bodies in them. This subject-matter does not appear in the Specification as accepted.

Abstract: 568,316. Fuzes for flares &c. MIDGLEY, A. H., and MIDGLEY, A. M. March 9, 1942, No. 3071. [Class 9 (i)] A fuze particularly for flares discharged from aircraft but applicable to other uses, in which the striker is released for operation under the action of a spring by movement of a screw, comprises a spring-pressed striker held against striking movement by a lever or levers which transmit the spring pressure to a retaining member which is released by operation of the screw, the pressure between the retaining member and the screw depending upon the leverage adopted. The striker head is formed as a cup a with a projection a<1> and perforations a<2> adapted to receive the limbs d of a U-shaped member, which limbs pass through apertures c<1> in an abutment plate c which supports loosely on its upper surface two levers e the ends of which engage respectively the limbs of the U- shaped member and the outer extremities of a retaining bar-member f. The levers and the retaining member are positioned on the abutment plate by studs i. A spring b extends between the abutment plate and the striker and a screw g operated by a vane h engages both the member f and the abutment plate. The pressure of the spring b is transmitted through the U-member d to the levers e and thence to the retaining member so that the pressure between the latter and the releasing screw g can be modified by varying the lengths of the levers. A single lever may be used and the retaining member and screw may be used with a number of strikers and lever arms.
