Abstract: 755,365. Vehicle headlamps; systems of lighting. MULLER, A. June 2, 1954 [June 8, 1953], No. 16316/54. Classes 75(3) and 75(4). An articulated headlamp casing 29, Fig. 5, adapted to be mounted below the body of a vehicle is mounted on an outwardly protruding enlarged, preferably integral, head portion 27 of a toothed rack 26 guided in a tube 25 fixed to the vehicle chassis, said casing being clamped to the head projection 27 by clamping a convexly shaped, e.g. spherical rear portion 28 of the casing into a vertically disposed concave recess 52 on the head portion 27 as by a bolt 30 passing through a vertical slot 38 in the hollow part 28 and through a bore 36 e.g. of rectangular cross-section, in the socket 27 to be secured by a nut 43 and washer 42. The casing 29 is thus angularly adjustable up to 35 degrees up and down in a vertical plane. The rack in the form of a rod 26 telescopes within a split tube 25 having internal arcuate oppositely disposed shoulders 33 to engage in adjusted position a pair of oppositely disposed arcuate grooves 35 on the rod, the tube being then tightened by a ring 31 at the end and retained by external projections or rim 34. The rod is rotatably adjustable in the tube and the grooves 35 may be replaced by a screw thread. The tube 25 is secured as by welding to a mounting plate 44 fixed as by bolts 46 to the vehicle floor 47, a counter plate 45 having shaped recesses for the bolt heads. In an alternative construction the tube 25 may be secured in a tubular head of an L-shaped member adapted for attachment to an angle-iron beneath a lorry. Two such lamps 10, 11, Fig. 1, are mounted one on each side of the driving shaft 13 in front of the rear axle 12 at a distance of the order of the radius of the road wheels and so directed that the beam from the left hand lamp 10 is directed upon the left hand front tyre 14 and the beam from the right hand lamp 11 is directed slightly outside the right hand tyre 15 and at a sufficiently low angle as not to be intercepted by any intervening part of the chassis. Alternatively the lamp 11 may be directed on to wheel 14 and the lamp 10 just outside the tyre 15 and the lighting circuit is such that either the main headlamps may be switched alone or the dipper filaments thereof and the subchassis lamps 10, 11 may be switched on together, e.g. in parallel.

Title: Conductor selection matrices
IPC: H03K17/62
Filed: 1972-04-10
Abstract: 1385524 Displays and code conversions OWENS-ILLINOIS Inc 10 April 1972 [19 April 1971] 16354/72 Heading G4H [Also in Division H3] A system for supplying operating potentials to a load device (e.g. a gas panel display) having row and column conductors, includes a first matrix for selecting one of the row conductors and a second matrix for selecting one of the column conductors, each of the two matrices having a plurality of cross-point elements each having a nodal point N connected to one of the conductors and at least three electrical paths to the nodal point, one path including a resistive element R1 and the other two containing respective unidirectional conducting devices Dl, D2, there being means for applying a pulse potential between a common point and the end of the resistive element remote from the nodal point, one of the unidirectional conducting devices D2 being connected directly between the nodal point and the common point, and there being a non-inductive switching device between the end of the other unidirectional conducting device D1 and the common point and means for applying a switching signal to the switching device to give it a high impedance. To select a cross-point in one of the two matrices, the corresponding one of a number of column transformers 20 is pulsed to render a transistor T1 in the cross-point conductive. This tends to raise the potential at N. and via diode D render the SCR shown conductive but such conduction is prevented at the required cross-point by a pulse applied to the corresponding one of a number of row transformers 25. A square, sinusoidal or trapezoidal periodic sustain waveform is applied from a generator 10 (another generator supplying an inverse waveform to the other dimension of the gas panel via the other selection matrix). Fig. 3a (not shown) shows a modification in which all the polarities are reversed. Figures 4a, 4b (not shown) show modifications (with respective polarities) in which the SCR is replaced by an NPN transistor (though a PNP transistor could be used). Fig. 5b (not shown) shows a modified connection of transistor T1 of Fig. 1, with reversed polarity. The transistor T1 in either connection could be PNP instead of NPN. Specification 1,385,525 is referred to.

Title: Circuit Arrangements for Imitating the Touch of Percussive Musical Instruments
IPC: G10H1/055
Filed: 1968-04-05
Abstract: 1,164,422. Electronic musical instruments. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 5 April, 1968 [8 April, 1967], No. 16538/68. Heading G5J. A circuit for imitating the touch of a percussive musical instrument is arranged so that the build-up time of the note from a tone generator G is made independent of the duration of actuation of the key T. The key is mechanically coupled to a magnet M which induces a voltage pulse in an inductance L on actuation of the key. This voltage pulse is used to charge up a capacitor C through a diode D, and is also fed to the base of a transistor Tr, causing it to conduct and so ground the base of transistor O which is thereby switched off and does not pass any signal from generator G. At the end of the pulse, transistor Tr is switched off and the voltage stored in capacitor C is fed through resistor R to the base of transistor O which is hence switched on and passes a signal from generator G to associate amplifying apparatus at a level depending on the voltage across the capacitor and hence the intensity of actuation of the key. Diode D 2  and capacitor C 2  prevent " bottoming " of transistor O if the key is depressed before the voltage across the capacitor C 1  has decayed to zero. Fig. 5 (not shown) illustrates a further embodiment in which the switching transistor Tr is arranged between the capacitor to be charged and the base of the transistor O and switches on after the capacitor has charged up to allow voltage from the capacitor to switch transistor O on.

Abstract: 422,396. Staple strips. VOGEL,M.,315, Mainzerlandstrasse, Frankfort-on-Main, Germany. June 7, 1934, No. 16885. Convention date, Dec. 29, 1933. [Class 83 (ii)] [See also Group XXV] Wire staples are produced from strips by pressing in the strip spaced grooves which pass from edge to edge of the strip and provide a weakened section for severing in the staple machine. Multiple strips 1 may be provided with longitudinal grooves 6 by being passed between rollers, of which the roller 4 is plain and the roller 5 is circumferentially grooved. At intervals, a distance B apart transverse grooves 7 are also formed. Instead of longitudinal grooves 2 with rounded edges 2<a> being provided on one side only, similar grooves may be provided on the other side, in which case the smooth roller 4 is replaced by a grooved roller. Alternatively, the groove may be produced transversely, in a single strip of the width of the complete staple and the rollers then have parallel longitudinal ribs. Instead of producing by means of rollers, the grooves may be produced by multiple presses or by a single press beneath which the strip is fed in steps or stages. In addition, the strip may be provided with a central rib or ribs 18 for the purpose of stiffening it and providing a guide when passing through the stapling machine. The edges of the staple are bevelled and the strip may be used in the flat or be preformed into U-shape for use in the stapling- machine.
