Title: Switching circuit and the combination thereof with a facsimile transceicer
IPC: H02M7/537
Filed: 1975-05-30
Abstract: 1518947 Inverting EXXON RESEARCH & ENG CO 30 May 1975 [30 July 1974] 23620/75 Heading H2F [Also in Division H3] In a switching circuit comprising at least one transistor 34, the transistor is rendered conductive by a series of relatively low voltage pulses coupled to the base via voltage isolation means 26, the interval between the pulses being less than the base storage time of the transistor so that the transistor remains conductive during the pulse series. The invention is applicable to the provision of a variable frequency substantially square wave for the synchronous motor 10 of a facsimile unit. Transistors 34, 36 are made conductive alternately by respective series of 2MHz pulses fed via respective isolating transformers 26, 28 or LED optical couplers. The pulses are derived from a logic circuit (Fig. 2, not shown) comprising a clock oscillator feeding a counter, the division being adjustable so as to control the effective final frequency, which in turn feeds a flip-flop a latch and further logic so arranged that the transistors 34, 36 cannot become conductive simultaneously.

[Class 83 (i)] In a centrifugal casting process the casting material is fed through a distributer arranged within the mould, the distributer having a slot formed by movable flat or curved faces which accelerate the flow of the casting material as it leaves the distributer. In one embodiment the slot in the distributer is formed by a sloping wall 1, covered with refractory material 10, and a roller 2, adjustably mounted so that the width of the slot may be varied. A bath of molten lead 11 may be arranged outside the wall for cooling purposes and the roller may also be hollow for the same purpose. In lieu of an adjustable axis the roller may be made eccentric so that the opening in the distributer varies between a maximum and zero or notches may be made around the circumference to give an intermittent flow. In another embodiment, Fig. 5, two pairs of rollers are provided, the lower pair 2<11>, 2 drive the upper ones 13, 14 by friction and are adjustable, they may also have eccentric axes or be notched. Driving means for the rollers may be such that their speed may be varied. The Specification as open to inspection under Sect. 91, describes also a feeding roller having a series of staggered recesses which permits a band of casting material to be fed having different thicknesses along its width.

Title: Improvements in or relating to road traffic signalling systems

Abstract: 509,395. Road signals for controlling traffic. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and TYACK, F. G. Oct. 6, 1937, No. 24293. [Class 118 (ii)] In a traffic integrator, a counter circuit effects operation of the integrator in one direction when the traffic density rises above a predetermined value and a time circuit measures off intervals and if the traffic density decreases to a value below the predetermined value during one of these intervals causes the integrator to operate in the opposite direction. The timer circuit comprises the condenser QT charged through a resistance TR and shunted by a neon tube CT in series with a relay T. Upon a vehicle actuating a road pad A, B or C relays CS, BR operate in turn, BR being slowto-operate so that a pulse is given to condenser CQ in the counter circuit irrespective of the speed of the vehicle. Relay EA controlling the circuits to be operated by the integrator remains de-energized while the traffic density is below the predetermined value, but upon the density rising above this level, neon tube CC flashes and relays E, ET and EA operate in turn, EA locking up and ET discharging condensers CQ and QT. As long as the traffic density remains at a level above the changeover level, E will operate before T and EA remains locked up. Upon the density falling below the level, T operates before E, causing relay TA to pull up and open the holding circuit for EA. Specification 471,608 is referred to. Reference has been directed by the Comptroller to Specification 352,601.

Abstract: 688,066. Compressed air engines; engines valvegear. SPRAGUE DEVICES, Inc. Oct. 6, 1950 [Oct. 17, 1949], No. 24445/50. Classes 122(ii) and 122(iii) [Also in Group XXIX] A fluid actuated motor 10 which may operate a wind-shield wiper, has an oscillatable member 14 responsive to fluid pressure and a reversing valve 22 mechanically actuated by said member, and is connected to a source 84 of fluid pressure by a system including a manual control valve 86 and a differential area valve 88. The valve 22 comprises members 42, 46 interconnected by a toggle mechanism 54 connected to a link 68 projecting from the piston 14, so that in its end position to the left the toggle is moved to the position shown in Fig. 2 wherein the heads 44 and 48 are seated, and in its end position to the right the toggle is actuated to move the valve members 42, 46 to the right, seating a seal 45 and seating the head 48 against a hollow plug 74 which has bores 78 connecting passages 28 and 36 via a passage 70. When the manual control valve 86 is closed, shutting off supply to the conduit 112, fluid from the source 84 flows through conduit 114 on to the small piston 94 of the valve 88 to lower the valve member 98. If the valve 86 is closed when the piston 14 is moving from its extreme left position towards the right, the valve members .42, 46, and 98 will be positioned as in Fig. 2. Pressure fluid will flow from conduit 114 and housing 90 via port 104, conduit 116, port 80, past member 42 into the cylinder 12, fluid at the other end of the cylinder exhausting through passages 26, 28, 70, into plug 74 and space 38, and into bore 81 leading to conduit 118, port 106, and vent 108, so that the piston 14 moves back to its left position, where it will remain with the wiper "parked". Similarly, if the valve 86 is closed when the piston is moving to the left, fluid will flow to the valve 22 via conduit 116 and exhaust through conduit 118 but since the members 42 and 46 will be in their right hand position, the piston will be moved back to the right hand end of its cylinder. When the valve 86 is open pressure fluid flows in both conduits 112 and 114 but since piston 96 is larger than piston 94, the valve member 98 is raised, conduit 118 becomes the supply line to the valve 22 and exhaust is through conduit 116 and vent 108. With the valve members 42 and 46 to the left, as in Fig. 2, fluid from conduit 118 enters port 81, plug 74, passages 28 and 26, to move piston 14 to the right, exhausting fluid through valve member 42, port 80, to conduit 116. At the end of its stroke the piston actuates the toggle mechanism to move the valve members 42, 46 to the right so that fluid flows from conduit 118 past valve member 46 to move piston 14 to the left until the toggle mechanism is again actuated and the cycle repeated.

By pressing in the knob w against the action of a spring, and so disengaging a pin x in the wiper shaft o from the driving sleeve y the wiper may be hand-operated independently of the motor.
