Abstract: 1487880 Screen printing frames STRETCH DEVICES Inc 15 Sept 1975 [19 Sept 1974] 37771/75 Heading B6C [Also in Division D1] A frame for a silk screen comprises a plurality, e.g. four, rollers 16, 18, 20, corner pieces 24, 26, each corner piece allowing rotation of the rollers but having means to lock each roller in a definite rotary position, each roller having means for attachment of the screen fabric. The rollers each have a set of teeth 70, and each is associated with two sets of teeth 54, 74, the set 54 being a fixed set of teeth carried by the corner member so that set 74, by engagement with the fixed set 54 and with set 70, fixes the roller against rotation. A pawl and ratchet 62 arrangement may be provided to temporarily hold the roller when the screen is tensioned by rotating the roller, e.g. using a spanner on hexagonal surface 86, and the teeth then brought into engagement by tightening nut 80. The carrier unit may be held together by wires 30 which can be tensioned to apply camber to the rollers, and liquid dams 40 having seals at their edges facing the screen may be provided. In another embodiment (Figs. 8 and 9, not shown), the dams form the means for holding the carrier members together. The screen may be attached to the rollers by means of a re-entrant groove and an element insertable therein (Figs. 5-7, not shown).

Abstract: 1,034,554. Automatic voltage control of rectifier systems. NORTH ELECTRIC CO. Sept. 18, 1964 [Sept. 24, 1963], No. 38249/64. Heading G3R. [Also in Division H2] The D.C. supply to a load 30 from an A.C. source 10 comprises a transformer 15 and rectifier bridge 25 providing a minimum fixed voltage, and a transformer 43 and rectifier system 47, 48 providing an additional voltage whose value is varied between zero and a maximum by alteration of the firing angle of silicon controlled rectifiers 41, 42 in response to signals from a control circuit 34, the arrangement providing a constant output voltage across the load 30. When rectifier 41 or 42 is fired conduction is transferred from rectifier 19 or 20 to rectifier 47 or 48 respectively, the total heat dissipation associated with these rectifier pairs thus being independent of the firing angle for a given load current. The transformer 15 is operated at a higher flux density than transformer 43. The invention may be applied to a single-phase, full wave, centretap rectifier system, to a bridge-type polyphase rectifier, and to a polyphase double-star rectifier system, Figs. 3, 4 and 5 (not shown). The silicon controlled rectifiers may be replaced by thyratrons or ignitrons.

Abstract: 1435138 High frequency plasma torch VEREINIGTE EDELSTAHLWERKE AG 17 Aug 1973 [8 Sept 1972] 39009/73 Heading H5H [Also in Division H2] A high frequency "cold plasma" torch in which the conductive torch tube 1 through which plasma forming gas flows is connected to a high frequency generator 12, is ignited by temporarily connecting an insulated metal pin 5 within the tube 1 to earth to cause an arc between the pin 5 and tube 1. The tube 1 is connected to generator 12 by closure of switch 11 and the pin 5 is temporarily earthed by depression of a push button switch 10 which causes a circuit breaker or high speed contactor 9 to complete the earth circuit. After ignition the earth connection is broken. The torch is used for two stage surface hardening in which a thin surface layer of metastable austerite formed by rapid heating and cooling is converted to a tough martensite structure. The earthed metal pin 1, e.g. of tungsten, is insulated from tube 1 by an insulating member 4. The plasma gas is supplied to tube via an inlet 3 and the plasma exists through a tungsten nozzle 2.

Abstract: 861,812. Control of motors. SOGNI, G. Dec. 18, 1957 [Dec. 22, 1956], No. 39376/57. Class 38 (3). The slip energy from a wound rotor induction motor 1, 2, is rectified by rectifier 9 and fed to the armature 6 of a D.C. machine on the same shaft. Speed control is effected by means of variable resistor 14 or by varying the field excitation of the D.C. machine. Alternatively, the stator winding 1 may be adapted for stardelta conversion, or the winding may be tapped. A braking torque may be developed by shunting commutator 11 by a resistor, or by reversing the polarity of the D.C. field winding and connecting a resistor between the commutator 11 and rectifier 9. When the induction motor is supplied from a single-phase source, its rotor having a polyphase winding, the rectifier is protected against induced voltages of high frequency and amplitude at standstill by being shunted by capacitors and series-connected with inductors.

Filed: 1971-08-23
Abstract: 1356818 Fluid pressure brakes TOKICO Ltd 23 Aug 1971 [22 Aug 1970] 39431/71 Headings F2E and F2F In a dual hydraulic braking system a tandem master cylinder 31 supplies fluid to wheel brake units 40, 41 by way of a pressure regulator 1 which maintains a constant pressure ratio between the two independent circuits of the system and which actuates a switch when pressure in either circuit fails to give a visible warning. Pressure fluid from one chamber 33 of master cylinder 31 passes via line 36 to a chamber 6 of regulator 1 and then via lines 38a, 38b to chambers 44a, 43a respectively of disc brake and drum brake wheel brake units 40, 41. Pressure fluid from the other chamber 34 of master cylinder 31 passes via line 37 to chamber 7 of regulator 1 and then via lines 39a, 39b to chambers 44b, 43b of wheel brake units 40, 41 respectively. Since the pressure in chambers 6, 7 acts on opposite ends of different effective areas of a stepped piston 3, minor differences in pressure in the two circuits are compensated by movement of piston 3 which expands or reduces the volume of fluid to wheel brake units 40, 41. If either circuit pressure fails due to pipe rupture or leakage past a seal, piston 3 is displaced from its neutral position causing a plunger 18 to be correspondingly displaced so that a shoulder 18d or 18e closes a switch circuit by engagement with a contact pin 25 thereby causing a lamp 27 to be illuminated. In addition to a visible warning an audible warning may also be used.

In a machine for continuously printing a travelling web of material and having a number of printing cylinders 9 arranged about an impression cylinder 2 and driven in common by a central toothed wheel 7 through gear-wheels 18 mounted on the spindles of the cylinders 9, the spindles are mounted in bearings 17 which are radially slidable in a frame 14 which is separate from the main machine frame 1 and from the bearing members 11, 12 for the cylinder 2, and is movable laterally out of and into the machine in the direction A on rails 22, 23 arranged parallel to the axis of the cylinder 2. The printing cylinders 9 have associated inking fountains and rollers which are driven by devices connected to the spindle ends opposite those carrying the wheels 18 through a wheel 8 which is similar to the wheel 7. Each wheel 7 or 8 is driven by an independent motor 3 or 4 through gearing 5 and 6. The bearings 17 are connected to the pistons of hydraulic cylinders 13 by tie rods or the like which are releasably attached to the bearings whilst the cylinders are fixedly mounted on the bearing members 11, 12. On admitting pressure liquid to the cylinders the pistons draw the bearing 17 inwardly and thus force the cylinders 9 against the cylinder 2. After use, the frame 14 is removed in the direction A for any changing of the cylinders 9 that may be necessary whilst another frame 15 is moved into the machine from the right. Hydraulic devices 29, Fig. 1, are used to lock the frames in position. Gauge wheels 30, 31 having diameters equal to the cylinder 2 and the wheel 7 or 8, respectively, are used in order to roughly adjust-for purposes of registration &c.-the cylinders 9 and associated driving mechanism prior to the insertion of a frame into the machine, final adjustment being effected when the frame is locked in printing position. More than two frames 14 or 15 may be associated with the machine.

This arrangement enables the response at low frequencies to be varied while the response at higher frequencies is substantially independent of the reference voltage, Fig. 2 (not shown). In an alternative arrangement, Fig. 3 (not shown), a control voltage is applied across a potential divider comprising resistors (22, 24) and a diode (27) thereby determining the amount of feedback to the amplifier (21).

In the embodiments of Figs. 3 and 5, the response at high frequencies can be varied while the response at low frequencies is substantially independent of the reference voltage.
