Title: Burglar alarm system
IPC: G08B13/194
Filed: 1966-04-21
Abstract: 1,134,877. Burglar alarms. A. A. LARGE. 17 March, 1967 [21 April, 1966], No. 17500/66. Heading G4N. In a burglar alarm system, objects in a room are scanned by an energy beam (e.g. ultraviolet), the reflected energy being converted into a pattern of electrical pulses which are recorded so as to provide a reference pattern, the scanning and conversion being repeated at intervals, to provide further patterns of pulses which are compared with the pre-recorded pattern, a signal being generated when the two patterns do not coincide. As shown, a source 1 of visible light, ultra-violet, infra-red or ultrasonic waves is focused on a semi-silvered mirror 2 so that part of the energy is reflected on to a rotating mirror 3 which scans the room. Reflected energy is directed by the mirror 3 on to a condensing lens 8 which focuses it on to a photo-multiplier 9. The energy received at 9 is interrupted by a rotating partly-silvered mirror 7 so that the amplifier 10 provides a pulsed output. Energy from source 1 is also reflected by mirrors 4, 5 on to the partly-silvered mirror 7 so as to provide datum pulses the magnitude of which is adjustable by a balancing wedge 6 so as to be equivalent to the energy reflected from a grey object in the room. The pulses from amplifier 10 are first recorded on a continuous loop of magnetic tape (Fig. 2, not shown) after which, the recorded pattern is compared with subsequent scans of the room. The rotating mirror 3 may be tilted by means of a solenoid 11 so as to scan at different levels, the tape recorder being simultaneously switched to different tracks.

Title: Toy unit
IPC: A63F9/00
Filed: 1972-04-17
Abstract: 1348202 Toys with moving parts A JACOB1 17 April 1972 [20 April 1971] 17601/72 Heading A6S A toy comprises a frame 1 on which are pivoted bars 2 at such a distance from each other that when the first is tilted from the upright position shown it falls over, hits the next which also falls over, and so on. The bars 2 are secured by pivots 3 between the sidewalls 1a, 1b of the frame 1, and each carries an angle bracket 4 which prevents turning in the anti-clockwise direction. As shown the frame 1 is straight, but it may alternatively be curved, so that several such frames may be assembled to form a circle or S-shape Figs. 2, 3 (not shown). In another form, the bars (5), Fig. 4 (not shown) are pivoted on a plate (6) carrying to one side parallel musical strings (8). Each bar (5) carries a laterally extending striker (9) which hits a string as the bar falls over, to make a musical noise. In yet another form, bars pivot between the parallel sides (12), Fig. 5 (not shown), of a frame, extending both above and below the frame, the major portion of each bar extending through and below the frame while the minor but weightier part extends above the frame. In an extension of this form, a second set of bars, parallel to the first, is pivoted in a frame (15a), Figs. 6, 7 (also not shown). The end bar of the second set of bars carries a rod (18) extending laterally into the first set of bars. Thus tilting of the second set of bars is transmitted to the first set of bars, so that they also tilt. The bars 2, &c of the various embodiments may be connected by a string pulled to re-erect them once they have tilted to the downwards position, or alternatively they may be re-erected by turning the toy upside-down.

Title: An improved electric circuit arrangement including a cathode-ray tube
IPC: H03K6/02
Filed: 1943-10-26
Abstract: 578,046. Valve amplifying circuits. PHILIPS LAMPS, Ltd. Oct. 26, 1943, No. 17660. Convention date, Oct. 1, 1942. [Classes 40 (iii) and 40 (v)] The deflecting electrodes in a cathode-ray tube are fed from a push-pull amplifier in which an impedance element interconnects the anodes and a second impedance is interposed between an adjustable tapping of the first impedance and a point of low signal voltage. The input voltage is applied to one valve of the push-pull pair and the grid of the second valve is fed from the tapping on the first impedance. The adjustable tapping produces degenerative feed-back network and enables both phase and voltage balance of the amplifier to be obtained and also neutralization of the effects of stray capacities. As shown, similar amplifiers 20, 21 and 30, 31 are provided for the vertical and horizontal deflecting voltages respectively. The horizontal deflecting voltage is applied to the input grid 20b of the amplifier 20, 21. The anodes are directly connected to the deflecting electrodes 16 of the cathode-ray tube 10 and are also connected together by the resistance 22, the tapping on which is connected through the resistance 24 to the high tension supply. The voltage across the resistance 24 is applied through condenser 26 to provide the out-ofphase voltage applied to the grid 21b. The voltage source energizing the amplifier has its negative pole connected to the positive pole of the cathode-ray tube energizing voltage source and its positive pole connected to the amplifier. The potentiometers 40, 41 serve to provide adjustable voltages for the focusing electrode 14 and control electrode 13 so as to control the focusing and intensity of the beam. If amplifier valves of high amplification factor are used, the cathodes may be directly grounded and the bias resistance-condenser combination 28, 29, otherwise used, may be omitted. In the former case, grid bias for operating the valves is obtained by rectification of signal voltages. Instead of the triode valves shown, tetrode, pentode or other multi-grid valves may be used.

Abstract: 1281606 Electro-erosion SPARCATRON Ltd 19 April 1971 [14 April 1970] 17764/70 Heading B3V Undesirable arcing in an electro-erosion gap is ascertained when a gap monitoring circuit registers a normal gap voltage and/or current and a device simultaneously registers a widening of the space between the electrode and workpiece. In one embodiment, a roller 10 is spring urged against a bar A attached to the electrode E. An arm 17 is pivotable on the roller axis between stops 19 and 20 and is spring urged into engagement with a friction disc on the roller 10. As the electrode E is moved downwards by a servo system the arm 17 is pivoted against the stop 19. When the electrode is raised, the arm 17 is pivoted towards the stop 20 and if the maximum allowable gap width G1 is exceeded a microswitch M on the stop 20 is actuated by the arm 17. If a normal gap voltage and/or current is simultaneously registered by a gap monitoring circuit, a relay is operated to cause operation of a visual or audible warning and/or disconnection of the machining power and/or full retraction of the electrode E. In another embodiment (Fig. 1, not shown) a block (B) spring urged against the bar A, is held on a lower stop (D) during lowering of the electrode and is movable with the bar A towards an upper stop (F) during raising of the electrode.

Abstract: 466,991. Delivering materials from hoppers. COPPEE & CIE, E. June 26, 1936, No. 17786. Convention date, April 21. [Class 78 (i)] Discharging means for a bunker having an elongated discharge orifice 3 comprises a plurality of scoops 7 which are oscillated beneath the orifice to receive material from the bunker 'shoot during the outward swing and to push the material over its edge during the inward swing. The orifice 3 is divided by partitions 4, 5, 6 into sections each of which is fitted with a scoop 7, and each scoop is suspended by links 11 from pivots 12 on said partitions, so as to be nearer the inner longitudinal wall 2a of the bunker shoot than the outer wall 2d of same. The oscillation of the scoops is effected by eccentrics fixed on a rotating shaft 21 and coupled to the scoops by rods 19, the eccentrics being disposed at 90‹ angular distance apart to effect successive discharge from the several orifice sections. A regulator 2f on the outer wall 2d can be displaced to modify the delivery. The swing of the scoops 7 may be made adjustable by employing eccentrics built up of an inner eccentric 28 fixed to the shaft 21 and an outer eccentric 20 riding on and adjustably fixed to the eccentric 28 by a conical key 30 engaging a groove 20a in the eccentric 20. The orifices discharge the material on to an endlessband conveyer driven by the same motor 31 as drives the shaft 21.
