Title: Horizontal Deflection Circuits for Cathode Ray Tubes
Inventor: GELLER WILLIAM
IPC: H04N3/18
Filed: 1967-10-25
Abstract: 1,187,500. Transistor sawtooth circuit. GENERAL TELEPHONE & ELECTRONICS LABORATORIES Inc. 25 Oct., 1967 [17 Nov., 1966], No. 48590/67. Heading H3T. A line output stage for a television receiver utilizes an output transistor 48 turned on by a sawtooth driving signal of such magnitude that the transistor is just saturated during the whole of its conductive period and is turned off by a separate turn-off circuit 13. As described, the circuit is controlled by an oscillator 11 providing square waves at windings 42, 43, the former turning on transistor 44, inductor 45 providing a sawtooth current at the collector which drives output transistor 48 into saturation, giving a linear rise of current in deflection coils 51. Each sweep is terminated by the other half cycle from oscillator 11 which turns on thyristor 53, connecting the base of transistor 48 to a reverse biasing potential-V 2  sufficiently great to break down the base/emitter circuit of transistor 48. This gives rapid removal of charge carriers and hence rapid turn off of the transistor. Diode 49 prevents reverse baseemitter current. Diodes 15, 47 and capacitors 16, 46 provide resonant return for deflection coils 51 and inductor 45 when transistors 44, 48 are turned off so as to terminate each sweep. An S-shaping capacitor 52 and an E.H.T. circuit 54, 55 are provided.

Title: Pyrophoric lighter actuating mechanism
Inventor: SMITH JAMES DONALD
IPC: F23Q2/167
Filed: 1962-12-27
Abstract: 973,329. Cigar lighters. RONSON CORPORATION. Dec. 27, 1962, No. 48716/62. Heading F4F. A lighter actuating mechanism comprises a clutch member 24 for rotation of a sparking wheel 46, the clutch member including a pliant friction surface 37 brought into frictional contact with the abraded periphery of the sparking wheel when the fiinger-piece 12 is manually depressed. The clutch member 24 is attached to or formed integrally with a nylon or polyacetal closure cap 14 pivoted about the pivot pin 18 of the sparking wheel 46 and including a snuffer portion 22 provided with a metal insert 58 containing a spring- loaded ball 60 which depresses a burner 44 to close a gas valve assembly 54. The clutch member 24 is divided by slots 28, 29 into two frame members 30, 32 and a central clutch element 36, the base of which either forms or supports the friction surface 37. The central clutch element 36 has a transverse groove 38 to give it a spring-biased hinged connection 39. When the clutch element is undepressed there is a small clearance 47 between the friction surface 37 and the sparking wheel periphery. A pin 62 passes through elongated transverse holes 40, 42 in the frame members and a circular transverse hole 44 in the clutch element 36 and is attached to tabular protrusions at the end of the finger-piece 12. A horizontal slot 64 in the end of the fingerpiece remote from the sparking wheel engages a horizontal pin 66 in the lighter body. A leaf spring 68 biases the finger-piece 12 upwards. On initially depressing the finger-piece 12 the friction surface 37 is forced down against the sparking wheel 46 so that further movement of the finger-piece causes the sparking wheel to rotate against a flint. In the fully depressed position of the finger-piece 12 the clutch element 36 is disengaged from the sparking wheel so that on releasing the finger-piece the sparking wheel remains stationary. In a modification, Fig. 8 (not shown), the spring-loaded ball in the snuffer portion 22 is replaced by a spring-loaded pliable heat resisting sheet material which closes the end of the burner 55, thus obviating the need for a gas valve assembly, and the horizontal slot 64 in the finger-piece is replaced by an arcuate slot having an initial horizontal section to provide initial clutch engagement action. In a further modification, Fig. 9 (not shown), the finger-piece 12 is pivoted about a pin and a transverse pin through the clutch element slides in an arcuate slot in the finger-piece and the clutch element is attached to the closure cap by a leaf spring. In a further embodiment, Fig. 12 (not shown), the clutch element is not attached to the closure cap but hung by a transverse pin linking the finger-piece and a metal closure cap, the finger-piece engaging this pin by a horizontal slot.

Title: Method of precoating a filter
IPC: B01J47/12
Filed: 1971-10-25
Abstract: 1368319 Filter cartridge and depositing filter aid thereon ECODYNE CORP 25 Oct 1971 [9 Nov 1970] 49437/71 Heading B1D Filter aid is applied to the outside of a filter cartridge 30 comprising a perforate core covered with two layers of mesh and having its upper end enclosed by an inverted cuplike member 70 which defines a chamber where any gas trapped in the cartridge when the tank 12 is filled with liquid can accumulate, so that such gas does not prevent deposition of filter aid on working parts of the cartridge. The member 70 may have a vent hole (72) covered by mesh (Fig. 2, not shown). In use several cartridges operate in parallel in tank 12, which is first filled with water through reverse. flow inlet 57 with air vent 55 open and held at a pressure of 8 p.s.i. Thereafter a slurry of ion exchange resin or diatomaceous earth filter aid is pumped from vessel 40 round circuit 41, 43, 44, 14, through cartridges 30, 16, 52, 49 to deposit the filter aid on the cartridges, the pressure in tank 12 being raised to 16 p.s.i. and maintained there during the latter stage of deposition, when valves 42, 52 are closed and valve 54 opened, and during the subsequent filtering stage. The increase in pressure compresses the gas trapped in the upper end chambers of cartridges 30 and forces some out through the vent holes (72). After filtering, during which water flows from inlet 46 to outlet 48, the cartridges are cleaned by reverse flow and tank 12 drained via outlet 56.

Title: Process and apparatus for the manufacture of fibres from attenuable materials
IPC: C03B37/06
Filed: 1977-12-02
Abstract: A gas jet emitter (20) emits, through a series of orifices (21), a row of gas jets which are diverted and spread by a deflecting plate (40). The spreading of the jets is however limited by impact with the adjacent jets, which gives rise in each jet to counter-rotatary vortices (45, 48) surrounding a laminar flow zone (44) at low pressure, into which a thin stream (S) of molten thermoplastic material is sent. The jets are directed against a main gaseous flow (18) into which they penetrate, forming interaction zones. The thin streams are thus stretched successively in two steps, but the second step may be omitted. The method applies in particular to manufacturing glass fibres. <IMAGE>

Filed: 1963-12-23
Abstract: 988,497. Feeding sheets. MORANE PLASTIC CO. Ltd. March 5, 1964 [Dec. 23, 1963], No. 50765/63. Heading B6B. Apparatus for producing a stream of partly lapping sheets and for feeding the stream to a machine, includes a stop member which, during movement of a first sheet, holds back a succeeding sheet lapped with the first to an excessive amount until the lap is reduced to the desired amount, and then releases the second sheet to allow the two sheets to move together in lapping relation. As shown, the sheets are fed to a laminating machine 10, such as that described in Specification 860,322, wherein underlapped sheets are fed over a table 14 by rollers 30, 31 to be united to an overlying web by means of glue and a pair of pressure rollers 11, 12. The sheets are stacked on a table 15 which is vertically adjustable by means of a foot treadle or electric motor, and each sheet is placed manually on a platform 16 formed by the surface of a perforated conveyer belt 17 mounted on rollers 18, 19, 20, and continuously driven. A number of stops 21 are arranged transversely across the machine between the belt 17 and rollers 30, 31, and each stop can be raised and lowered by means of a solenoid 23 controlled by a variable speed unit 32 which is driven from the machine 10. Below the perforated belt 17 there are as many vacuum boxes 26 as there are stops 21, and the air pipe to each box is controlled by a magnetically-operated valve 29 coupled to the variable speed unit 32. In operation, a first sheet is placed on the belt 17 against the raised stops 21, and the unit 32 operates the solenoid 23 to retract the stops and also to operate the valves 29 to establish suction in the boxes 26, so that the sheet is fed into the nip of the continuously-driven rollers 30, 31. The unit 32 now raises the stops 21 and cuts off suction to the boxes 26, and a second sheet is placed manually on the belt 17 beneath the trailing edge of the first sheet and against the stops 21. When the first sheet has reached a position where the underlap between the sheets has been reduced to a predetermined amount, the unit 32 again operates to retract the stops 21 and establish suction in the boxes 26. The second sheet is now fed to the machine. The amount of underlap between the two sheets is thus controlled by the timing of the operation of the unit 32, and even if the speed of the machine 10 is varied, the underlap will remain the same.
