Abstract: 1,011,918. Electron beam deflecting apparatus. PLESSEY CO. Ltd. March 2, 1962 [Dec. 2, 1960], No. 41498/60. Heading H1D. A cathode-ray tube scanning coil assembly includes, at its forward end, a fixed auxiliary magnet arrangement comprising a complete, or split ring of magnetic material which produces a magnetic field generally transverse to the direction of line scan and extending over the effective scanning area. This field reduces pin cushion distortion in the vertical direction and tends to prevent barrel distortion at the top and bottom of the picture. As shown, the assembly includes a plastic element 3, interposed between the line and frame scanning coils, and formed with an axial flange 5 supporting the auxiliary magnet arrangement. Diametrically opposed cylindrical magnets 14 are fixed between arcuate pole-pieces 8, 9 by clips 15 to produce a substantially linear auxiliary field. The clips 15 may also support a plate for shorting out localized magnetic fields. A similar magnetic field may also be provided by a thermoplastic or rubber ring impregnated with magnetic material either alone or associated with two short magnets. Alternatively, two semi-circular magnetized strips can be used.

The height of the wall around each slit is preferably four times the thickness of the sheet, the walls being pressed out in the same direction as flanges 7 or 27 of the bar. The stiffening formations are also formed by pressing in the direction of extension of the flanges 7 or 27 and either extend transversely between the ends of adjacent slits, from and to positions close to adjacent slit rows, Fig. 2, or extend continuously across the web of the bar in zigzag fashion, Fig. 5. In both embodiments the spacing of the slit rows increases progressively towards the centre line of the bar, which preferably lies between two slit rows. In the Fig. 2 embodiment, the spaces between the ends of the slits in the various rows also increases towards the centre line of the bar, so that these spaces accommodate single formations 19, 20 or double formations 21. Additional diagonal formations are provided along the centre line of the bar. In this embodiment, the formations 19-22 may be either the ribs shown or slits with pressed out walls, whereas the formations 40-42 of Fig. 5 are essentially ribs.

A refuse disposal device comprises a preliminary compression chamber 3 having a force plate 8 reciprocable therein; means (illustrated in Fig. 3) for applying a cover around the block of refuse thus formed; and a secondary compression box 20 having a force plate 27 for compressing the covered block. As described, collected refuse is thrown into a hopper (43), Fig. 1 (not shown), and a lid (38) opens, whereupon hopper (43) pivots to throw the refuse into a feed box 2. A plate 5 advances the refuse into compression box 3, plate 8 compressing it against a door 13, expelling water through holes 19 to form a solid block G. Door 13 is next opened and plate 8 expels block G into a rectangular guide cylinder 1]. Wrapping the block.-As illustrated schematically in Figs. 5a . . . 6 (not shown), a sheet of wrapping material S<SP>1</SP>, which may be of plastic or of reticular material or a combination of both, e.g. plastics reinforced with wire mesh, is fed from a roll S through driven rollers (91), 92, cutting blades 86, 87 and rollers 79, 80 and under the guide cylinder 11 to rest on guide rods (97). A folder 52, see also Figs. 4, 5b (not shown), is now raised to wrap the sheet S<SP>1</SP> around three sides and a portion of the open end of the cylinder 11. Folders 54, 55 now advance towards each other so that tucking pieces 68, 73, see Fig. 3, fold protruding side portions of the sheet S<SP>1</SP>, see also Fig. 5c (not shown), across the open end of the cylinder. Interengaging elements 67, 72 fold the sheet over the upper side and form a longitudinal seam. Folders 54, 55 are withdrawn and a folder 53 is lowered, the tucking portions 58, 62 of the folders 52, 53 overlapping to complete the end closure. The block G is then expelled from cylinder 11, i.e. into the wrapper S<SP>1</SP>, after withdrawal of folders 52, 53. Folders 52, 53 now advance towards each other again, their tucking portions 58, 62 completing the wrapping at the rear end of block G, Fig. 5d (not shown). Secondary compression.-The wrapped block G<SP>1</SP> rests on a slidable door 47, Figs. 1, 3, and this is now opened allowing the block to fall into second compression box 20 where a plate 27 compresses the block G<SP>1</SP>. A door 32 is opened and a plate 23 expels the block into a discharge shoot 36.  The machine, shown as operated by hydraulic means, alternatively can be operated electrically throughout. It may have automatic control means including a time sequence device (not detailed). Modifications described include the provision of simplified compression boxes, Fig. 8 (not shown), where the plate (27<SP>1</SP>) serves both for compressing and subsequently expelling the material, e.g. in box 20, plate 27 would be omitted.

Title: Protective circuits for semiconductor voltage regulators

IPC: H02H7/06
Filed: 1970-09-10
Abstract: 1281099 Automatic voltage control GENERAL MOTORS CORP 10 Sept 1970 [15 Sept 1969] 43405/70 Heading G3R A voltage regulator generally similar to that described in Specification 1174729 is modified to dispense with the filter capacitor of the protection circuit by using a voltage divider including a resistor 112 and a temperaturedependent impedance 114, the value of the former being high compared to the latter so that the protection circuit is insensitive to transient voltages appearing between the circuit point 62 and earth. The impedance 114 may comprise a single thermistor or various combinations of the latter with one or a pair of resistors, Figs. 2A to E (not shown). The positions of members 112, 114 may be reversed, in which case member 11.4 comprises a fixed valve resistor and member 112 is an impedance having a positive temperature co-efficient of resistance, the ratio of the two again being chosen to prevent response to transient voltages. In operation, an overvoltage condition caused by a disconnection between members 26, 30 causes the voltage at point 122 to reach a value sufficient to turn on a transistor 116, which causes turn-on of a transistor 50 forming part of the voltage regulator which normally maintains the generator voltage at a value set by a Zener diode formed by the emitter-base junction of a transistor 84. The overvoltage condition thus over-rides the control effect of members 102, 84, 52 to cycle the field winding control transistor 40 on and off, via a Darlington amplifier 64 forming a semi-conductor switch, so that the generator voltage is regulated to a value higher than that set by the transistor 84. The member 64 is controlled by the voltage at point 82 to provide the protective feature described in Specification 1220538 should the members 80, 82 become disconnected. If this feature is not required the member 64 may be replaced by a diode, Fig. 3 (not shown), which modification also includes the replacement of transistor 116 by a diode having the same forward characteristics as the PN junction formed by the base-emitter circuit of the transistor. Transistor 40 is also-replaced by two Darlington-connected transistors. In further modifications, Figs. 4, 5 and 6 (not shown) member 64 is replaced by a diodeconnected transistor, thermistor 41 is replaced by a resistor, the resistor 112 is connected directly to circuit point 46 and the connections of transistors 50, 116 are changed. The resistance temperature characteristics of the impedance 114 is matched to the break-down voltagetemperature characteristic of the transistor 116 to provide temperature compensation for the protection circuit. A circuit comprising indicator lamp 190, resistor 194, ignition switch 192 and accessory switch 196 is connected as shown to prevent feedback into the ignition system.
