Title: Method and apparatus for detecting faults in a substantially  rectangular ac voltage
IPC: H02H7/122
Filed: 1970-12-23
Abstract: 1334370 Monitoring inverters LICENTIA PATENT-VERWALTUNGS GmbH 23 Dec 1970 [30 Dec 1969] 61129/70 Heading H2F In a method of detecting faults in a rectangular wave generator (e.g. an inverter) a D.C. pulse is arranged to straddle each rise time and each fall time of the monitored wave so as to prevent each rise and fall being detected as a loss of output. As shown, the rectangular wave output U w  of an inverter is full-wave rectified at 11, smoothed by capacitor K and used to power a D.C. pulse generator comprising capacitor 25<SP>1</SP> charged via resistor 25<SP>11</SP> until a uni-junction transistor 22 breaks down, when the output is used to trigger a transistorized monostable multivibrator 3 which provides the required D.C. pulse. The generator 2 is synchronized by the output of a full-wave rectifier 21 fed from the inverter output U w . Detecting failure of output or failure to commutate.-The inverter output U w  is also rectified at 11 and used to supply power to a pulse generator comprising a uni-junction transistor 12 which only becomes triggered if the voltage at base II is less than a predetermined value relative to the voltage of capacitor 15<SP>1</SP> at the emitter. A pulse is thus provided at A1 only if the output U w  falls between the end of one D.C. pulse and the beginning of the next pulse. Detecting faults during the superimposed D.C pulses.-The inverter output U w  is also fed via a centre-tapped transformer (not shown) in push-pull to transistors 43, 44 which thus become conductive on alternate half cycles and allow respective capacitors 45, 46 to charge during that time and discharge via diodes 48 or 49 during the other half-cycles. If capacitor 45 or 46 charges excessively due to a fault in the inverter, uni-junction transistor 47 is triggered, providing a pulse set A4 which is superimposed on the pulse A1 and fed via transistor inverting stage 5 to trip off the inverter.
Patent GB-664930-A (GB)
Abstract: 664,930. Spray-producers. SCHORT METALLISING PROCESS, Ltd. March 10, 1950 [March 21, 1949], No. 7668/49. Class 69 (iii). A pistol for coating surfaces by spraying a powder which is melted or sintered by a flame produced by burning a combustible gas, has the powderconveying nozzle 15 tapered towards the throat and an annular chamber 16 is interposed between the nozzle 15 and the outlet or outlets 7 of the passages at which the gas is burnt. The gas mixture is delivered from an inlet 2 via channels 5 and 6 to the fluted outlet 7, and powder, drawn in at 19 by an injector 11, is passed to the outlet 15. Between the outlets 7 and 15 is the fluted outlet 16 to which is passed cooling air from an inlet 8, radial passage 12, and annulus 14. This air forms a cold sheath protecting the air-powder mixture, emerging at 15, from the flame emerging at 7, and ensures its melting after leaving the outlet 15. The injector 11 is retained by a spring 22 fitted in a detachable cap 23, the air to the injector also being supplied from.the inlet 8. If desired, the combustible gas mixture may be conveyed by holes 24, Fig. 2, to an annulus 25 having peripherably dispersed apertures 26, the powder emerging from 27 being then heated by radiation only. The cool air. sheath is retained however. Another embodiment, Fig. 4 (not shown), differs in that the powder is fed by pressure, and not by means of an injector, the apparatus otherwise being similar to the first described embodiments. Specifications 432,831, 624,066 and 644,280 are referred to.

Title: Perforating rod-like articles
IPC: A24C5/60
Filed: 1979-04-02
Abstract: A perforating device for double- length filter cigarette assemblies, in which cigarettes are transferred from the drying drum (2), of a plug assembler onto a first conveyor (4) which conveys them into the space between a straight flight of the first conveyor (4) and parallel flight of a second conveyor (6). The speed of the first conveyor is varied cyclically relative to that of the second by means of a speed modulator 30, so that the cigarettes are rolled in successive steps during their travel through the device, so as to present successive different segments of the outer circumferential surface of the central filter portion to a perforator device (8). The perforator is reciprocated parallel to the conveyors in synchronism with the movement of the cigarettes through the device, whilst also being reciprocated perpendicular to the conveyors so as to perforate the cigarettes at the instant at which their rotational speed is zero, at which point there is therefore no relative rolling between the pins and the cigarettes. After perforation the assemblies are transferred back to the drum (2) of the plug assembler. <IMAGE>

Liquid in the bore (12) can also pass through a restriction (21) between parts (6) and (7) to be ejected through the ring nozzle (7) and thus create an enforced air-flow through the recess (3) to the drum end face. The restriction (21) may be varied by rotating the nozzle (7) relative to the tube (5) by means of the screw-thread (13). <IMAGE>
