Title: Improvements in or relating to riveting machines
IPC: B21J15/26
Filed: 1959-10-21
Abstract: 919,291. Riveting. BIFURCATED & TUBULAR RIVET CO. Ltd., and SHACKELL, A. Oct. 5, 1960 [Oct. 21, 1959], No. 35670/59. Class 83 (4). A riveting machine comprises a riveting plunger 1, a holder 6 adapted to support a rivet between said plunger and a workpiece location, first means operable to move said plunger into engagement with the rivet and thereafter to drive the rivet through a workpiece and second means operable after the plunger has engaged the rivet to move said holder towards the workpiece at a speed slower than that of the plunger, the holder being maintained stationary prior to said engagement. The plunger 1 which carries a riveting head 4 and the holder bar 2 which carries a holder 6 both slide in a rigid frame member 3. An operating lever 9 is pivoted to the frame at 10 and engages a channel member 11 at the upper end of the plunger 1. Pivoted to the upper end of the holder bar 2 is a control lever 12, which rests on a peg 13, fixed in the operating lever 9, and is acted on by a spring 14 anchored to the frame at 15. The lever 12 has a projection 16 which limits the pivoting of the lever relative to the plunger bar 2. Two stops 17 and 18 limit the travel of the holder bar. When the lever 9 pivots to drive the plunger downwards the peg 13 moves away from the control lever 12, which rotates due to the spring 14 until the projection 16 engages the holder bar, so that during the first part of the movement of the plunger 1 the holder bar 2 remains stationary. The projection 16 engages the holder bar as the riveting head 4 engages the rivet. As the peg 13 continues downwards the control lever 12 acts as a fixed extension of the holder bar 2 which begins to move downwards due to the spring 14 but at a slower speed than the plunger bar due to the location of the peg 13. Towards the end of the riveting stroke, stop 18 abuts the frame so that when the stroke is completed the riveting head 4 and the holder 6 are in the positions 4a and 6a. The timing of the movements of the plunger 1 and holder bar 2 may be altered by fitting collars of various diameters on the peg 13. In a modification (Fig. 3), the pivoting of the control lever 12 relative to the holder bar 2 is limited by an adjustable stop comprising a screw 21 and lock-nut 22.

Title: Improvements in or relating to circuit arrangements for television receivers and intended for filtering out noise signals
IPC: H04N5/213
Filed: 1955-12-14
Abstract: 800,146. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 14, 1955 [Dec. 17, 1954], No. 35902/55. Class 40 (3). [Also in Group XL (c)] In an impulse noise suppressor for a television picture receiver, a band of signal frequencies higher than the 20th harmonic of the line scan frequency is selected from the detected video signal on the assumption that largeamplitude signals in such a band are due more to interference pulses than to picture signals; and this band of signals is passed to an anodebend detector the output of which is used either to gate the synchronizing pulse separator (in the case of negative modulation) or to " black spot " the C.R.T. (in the case of positive modulation). In an embodiment for negative modulation the output of the last I.F. amplifier 5 is passed to a detector 7, amplifier 14 and hexode 20 which passes only the positive-going synchronizing pulses (plus interference pulses). Additionally the detector 7 is coupled to a tuned circuit 23, 24 having the response above mentioned and to an anode-bend detector 26 which provides a gating pulse to cut off the hexode 20 on the occurrence of an interfering signal pulse. A standing bias is applied via resistor 30 to delay the application of the gating pulses. In a modification, Fig. 3 (not shown), for positive modulation, the cathode-ray tube is conventionally cathode modulated and the output of the anode-bend detector is applied to the grid to act as a " black-spotter." Specification 799,132 is referred to.

Title: Grid-control of gas-discharge current-converters by means of a steady-voltage sensed by thyratrons
IPC: H02M1/04
Filed: 1960-10-20
Abstract: 904,127. Converting. BROWN, BOVERI & CIE. Oct. 20, 1960 [Oct. 23, 1959], No. 35963/60. Class 38 (2). In a current converter having grid-control discharge valves grid control pulses having a steep front and a constant amplitude are provided by a circuit comprising a thyratron 8 and a direct voltage source 7 in series with a resistor 3 in the grid circuit of a discharge valve 1. The instant of firing of the thyratron, and hence the commencement of the control pulse derived across the resistor 3 is variable and is determined by a variable-phase pulse generator 9, so that pulses may commence at times A, B, C or D (Fig. 2), for example. The control pulse is terminated by the application of a pulse U K  from a winding 5 of a fixed-phase pulse generator to the cathode of the thyratron via a rectifier element 6, the pulse U k  being great enough to terminate conduction. The phase instant of the pulses U k  is predetermined and may be early enough to preclude inverter operation. The discharge valve 1 may have a number of anodes and a common cathode. A grid bias source 2 may be included in the circuit of the valve 1. A polyphase arrangement is envisaged.
