Title: Improvements in and relating to the reduction of interference in electric signal transmission systems
IPC: H04B1/14
Filed: 1935-11-08
Abstract: 467,263. Wireless receiving systems. PERCIVAL, W. S. Nov. 8, 1935, No. 30991. [Class 40 (v)] In a receiver having a main highly selective signal channel and an auxiliary channel of lower selectivity adapted to reduce the amplification of the main channel during periods of transient interference, the auxiliary channel is provided with an A.V.C. circuit mainly responsive to continuous wave signals. The main channel comprising the valve V8 is fed from the input I1 through a delay bandpass network L10, L11, C3, C4, its output passing to the circuit P for translation. The auxiliary channel comprises a frequency changer VI, V2, and intermediate frequency valves V3 ... 6 feeding a diode rectifier V7 with a delay voltage applied thereto from the source V, the D.C. voltage developed by the diode being applied through filter L7 ... 9, R3 ... 4, C5... 7 to a grid of the valve V8 of the main channel. The carrier component in the auxiliary channel is maintained constant by feeding from the valve V6, a limiting valve V9. the output of which is rectified by a diode V10 which produces A.V.C. voltages for the valves V3, V4. In this way the amplification of valve V8 in the main channel is controlled only by transient interference in the auxiliary channel. The delay network in the main channel ensures that the valve V8 is disabled before the interference reaches it from its input I1, and the values of condenser C5 and the resistance in parallel therewith are selected to ensure that valve V8 is not restored until the transient has ceased to be applied thereto. The channels may be associated with the same or'different aerials and tuned to receive the same or different wavelengths, and may both be signal channels. For example the main channel may be used for the sound signals accompanying television signals received on the auxiliary channel. The auxiliary channel may control a plurality of " main " channels. The gaps produced in the signals of the controlled amplifier may be filled in as described in Specification 470,140. Specifications 446,663, 462,228, and 468,994 also are referred to.

IPC: G03B9/58
Filed: 1965-07-21
Abstract: 1,64,218. Photographic camera release mechanisms. PENTACON DRESDEN KAMERAUND KINOWERKE VEB. July 21, 1965, No.31026/65. Heading G2A. When the release device 6 of a photographic camera is depressed, it engages a plunger 7 which is also depressed against the action of a spring 9 carrying a pin 10 engaging a locking lever 4. The lever 4 is held as shown by a spring 5, stronger than the spring 9, so the pin 10 is pressed into a bore 8 in the plunger until the plunger itself engages the lever 4. Continued depression of the device 6 causes the plunger 7 to pivot the lever 4 against the action of the spring 5 so as to free a shaft 2 and close a switch 15, closure of the switch starting an electric motor to drive the shaft 2 which is part of the camera shutter mechanism. Depression of the plunger before it contacts the lever 4 closes a switch 13 to bring an exposure meter into operation. In another embodiment, Fig. 2 (not shown), the pin 10 is dispensed with.

Title: Improved gear cutter and method of relief-grinding the same
IPC: B23F21/22
Filed: 1933-11-11
Abstract: 414,256. Relieving milling-cutters. GLEASON WORKS, 100, University Avenue, Rochester, New York, U.S.A. Nov. 11, 1933, No. 31478. Convention date, Dec. 24, 1932. [Class 83 (iii).] Work - holdera.-The cutting blades 16 used in face mill cutters for cutting longitudinally curved tooth gears are relieved so that the side surfaces form surfaces of revolution whose generators extend from top to root of the blades. In the usual type of face mill gear cutter, alternate blades act on opposite side edges. In grinding the outside blades 10, the blades are secured in non-radial slots in a head 14, the angle of obliquity c of the slots being determined by the amount of relief required. Shims 13 may be used to adjust the radial positions of the blades. A cylindrical grinding wheel 20 is then arranged so that its axis 21 is parallel with the cutting edge of a blade, and the head and the wheel are rotated, the wheel being preferably reciprocated in the direction of its axis during its rotation. If blades having a zero pressure angle are to be relieved, the grinding wheel axis is arranged parallel to the axis of the head 14. A similar arrangement is employed to grind the inside blades 24, such blades being mounted in a head in non-radial slots which are oppositely inclined to those of the head 14. The grinding wheel may be fed perpendicular to the head axis and is preferably reciprocated axially as before. For grinding the top surfaces 40 of both inside and outside blades, the blades are secured in a head 42 in slots 41 which are inclined at the relief angle c<11> to the head axis and are ground by a wheel having its operative surface 46 perpendicular to the head axis. Alternatively, the top clearance may be obtained by moving the correctly inclined blades in a straight line across the grindng wheel. In the form shown, all the blades are ground on both side faces and are finally positioned in a cutting head, Fig. 6, having radial slots. The inside and outside blade surfaces 30, 16 then lie on conical surfaces having offset axes 55, 54 respectively. The cutter shown is adapted to operate in an intermittent indexing process, but the invention is also applicable to making face mill cutters of the hobbing type. In some cases the cutters may have curved cutting edges, the grinding wheels being dressed to the complementary curved profile.

Title: Improvements in or relating to control devices operable by radiant electro-magnetic signals
IPC: G08C17/02
Filed: 1957-10-10
Abstract: 843,511. A.C. signal receivers. GENERAL MOTORS CORPORATION. Oct. 10, 1957 [Oct. 22, 1956], No. 31690/57. Class 40 (4). [Also in Groups XXXVIII and XL (c)] A tuned amplifier for operating a relay when a predetermined frequency is received includes a valve fed from a less selective part of the circuit to produce a voltage opposing the relay operating voltage which restricts the energizing current produced by strong signals, and prevents operation of the relay when the signal is an impure one primarily consisting of noise. As shown, a tuned aerial 7 passes a received signal through amplifier valves T-1, T-2 to a transformer 66 whose windings are both tuned to the predetermined signal frequency. The secondary winding 64 is connected to the first grid 106 of valve T-4 to provide operating control of the anode current through relay winding 118. A signal from the primary winding 76 is also fed via capacitor 84 to diode 86 of valve T-3, the bias on the cathode 146 being adjusted by resistor 148 to be such that a signal strong enough to energize relay winding 118 also causes diode 86-146 to conduct, producing a negative voltage across resistor 88, which is fed via resistor 90 and secondary winding 64 to valve T-4, and prevents the current through winding 118 from increasing any further. Since the selectivity of the primary winding 76 is not as good as that of the secondary winding 64 the restraining voltage due to conduction through diode 86- 146 produces a sharp cut-off in the relay current when the received signal deviates from the predetermined frequency. The difference in selectivity of the primary and secondary circuits of transformer 66, and the time constants of the circuit, also ensure that a noise signal will produce sufficient restraining voltage and insufficient operating voltage, and therefore does not cause energization of winding 118. When winding 118 is energized an earth is removed from one end of resistor 138 so that a charging current flows through capacitor 136 which temporarily modifies the bias on grid 144 of valve T-3 and allows its anode current to augment the energizing current through winding 118, and hence prevent chattering.
