Title: Improvements in or relating to communication switching apparatus
IPC: G06F13/12
Filed: 1965-06-16
Abstract: 1042574 Communication switching systems INTERNATIONAL BUSINESS MACHINES CORP 16 June 1965 [30 June 1964] 25358/65 Headings H4K and K1K1 The invention provides means for establishing a connection in either direction between a data processing system and a plurality of out-stations. Communication over telephone lines is set up by dial digits from the processor via switching means, the switch controls being monitored so that, when the correct conditions prevail, the dial digits are passed between the switching means and the monitor. The processor is connected to an interface which feeds two sonic delay recirculating stores. The stores contain line control words (LCW), one for each of a plurailty of transmission channels. The stores are in synchronism with a multiplexing arrangement so that as each LCW becomes available the corresponding channel is selected. To establish communication the processor sends a control signal to the interface and the address of the desired channel. The address is stored in the appropriate LCW, and an acknowledgment sent to the processor. Subsequently, data passes from the processor to the chosen channel via the LCW and multiplexer. One of a number of control units is associated with each channel, to ensure that the character transmitted has the correct format. To set up a telephone channel, the processor passes address and dial command signals via the interface to the LCW. After checking for validity &c. dial digits pass to the LCW. Thence they are read out to a register and the call is established in known manner. Upon acknowledgement of the call data is passed to the line. All the switching control operations are monitored by circuitry associated with the circulating stores.

Abstract: 1,174,010. Controlling reactors. NUCLEAR DESIGN & CONSTRUCTION (1966) Ltd. 30 May, 1968 [1 June, 1967], No. 25388/67. Heading G6C. A control rod drive mechanism comprises a support roller chain 3, which is of sufficient length to permit the control rod 1 to drop to a fully inserted position within a control rod channel, connected at one end to the control rod 1 and at the other end to a point on an endless roller chain 4 via a connecting pin 5, to one side of the chain 4. The chain 4 is wound around a series of pulleys 6, at least one of which (6A) is connected to a motor (not shown) and provided with a fixed driving sprocket (not shown) for transmitting the drive from the motor to the chain 4. A further sprocket is also fixed on the pulley 6A for the support roller chain 3. Corresponding sprockets (not shown) are also fixed on the lowermost pulley 6B in order to ensure that the connecting pin 5 will at no time carry the full weight of the control rod. The drive mechanism is housed within a standpipe 2 for the control rod channel. A guide pulley 7 located in the standpipe 2 beneath the drive mechanism serves to centre the support chain 3 and the control rod 1 in the standpipe. When the control rod 1 is fully inserted, the support chain 3 is fully extended and its point of connection to the endless chain 4 lies at A. If the pulley 6A is driven in a clockwise direction, the endless chain 4 moves to wind the support chain 3 on to the pulleys 6 until its point of connection to the chain 4 reaches B when the control rod 1 is fully retracted.

Title: Improvements in or relating to sliders for sliding clasp fasteners
Inventor: BACKER JOACHIM
IPC: A44B19/28
Filed: 1955-09-05
Abstract: 771,751. Sliding clasp fasteners. AERO ZIPP FASTENERS, Ltd. Sept. 5, 1955, No. 25394/55. Class 44. A slider for sliding clasp fasteners comprises two opposed shields 1, 2 for guiding two fastener stringers through the slider, a riser element 5 being provided in fixed position on one of the slider shields 1 and extending through an aperture 12 on the other slider shield 2 which is supported by a support in substantially parallel relationship to the first shield 1, a portion 9 of the riser element overhanging an edge 23 of the other slider shield 2 bordering the aperture, the slider shield 2 being displaceable without substantial change of its general plane against the action of spring means 11 to such an extent that the edge 23 clears the overhanging portion 9 of the riser element, the arrangement being such that spreading is effected by displacing the shield 2 to clear the overhanging portion 9 so that the shield is no longer constrained to remain in the same general plane, and subsequently turning the shield 2 relatively to the first shield 1 about an axis at or near the ends of the shields adjacent the riser element 5. As . shown, the riser element is carried on a wedge-shaped portion 6 and includes a retaining plate 7 which prevents the stringer end that side of the slider from being removed from the slider when the shields 1 and 2 thereof are spread apart. The spring 11 is normally compressed between a face 13 on the shield 2 and the riser element 5 to maintain the portion 9 of the riser element 5 over the edge 23 of the aperture 12. A pull member 17 pivoted in a hole 8 in the riser element 5 is operative, when moved to the position shown in Fig. 5, to bear against a surface 14 on the shield 2 to move the latter forwardly to clear the portion 9 and subsequently to pivot the shield about a fulcrum surface 25. The slider may be re-closed by pressing together the narrow ends of the shields 1 and 2. In the normal position of the pull member 17, a locking projection 20 thereon enters an addi. tional aperture 16 in the shield 2 to engage between the fastener elements. In modifications the pull member may be dispensed with, in which case, opening of the slider is effected by displacing the shield 1 manually; the fulcrum 25 may be replaced by a pin-and-slot connection and the pull member may be arranged to bear against a surface 15 instead of the surface 14.

Title: Improvements relating to carburetters for internal combustion engines
IPC: F02M7/28
Filed: 1919-10-18
Abstract: 158,040. Rzetelski, V. Oct. 18, 1919. Spray carburettors.-Relates to floatless carburettors and consists in the provision and arrangement of main and auxiliary nozzles which operate alternately and automatically according to the position of the throttle valve. The carburettor shown in Fig. 1 comprises a main nozzle 4 disposed across the choke-tube 55 and an auxiliary nozzle 27 communicating with the suc-- tion pipe 2 in the vicinity of the throttle valve 3. Fuel is supplied to the nozzle 27 from a fuel inlet pipe 31 past a suction-actuated valve 21. The valve stem 23 carries a double disk regulator 26 situated as shown relatively to an air inlet 29. Below the regulator is an orifice 28, opening into the suction pipe 2, of larger area than the nozzle 27. When the throttle valve is closed, the engine suction draws in air by the inlets 28, 29 and lifts the regulator 26 and valve stem 23, thereby opening the fuel valve 21. When the throttle valve is opened, the suction at the orifice 28 is greater than at the nozzle 27, on account of its larger area. The air drawn in at the inlet 29 therefore exerts a downward thrust on the regulator, and keeps the fuel valve 21 closed. The mixture is therefore supplied to the engine by the main nozzle 4. The construction of the nozzle 4 is shown in Fig. 8. The nozzle comprises outer and inner perforated tubes 4<1>, 56, the outer tube being enlarged and screw-threaded at the end 4, or otherwise adapted, for insertion across the inlet pipe 1, as shown at Fig. 1. A rod 8 is slidably disposed within the tube 56, and carries at one end the fuel valve 9, the stem 11 of which is of polygonal section and slides in a circular bore 10. A disc 24 is carried by the other end of the rod 8. Suction in the inlet pipe 1 draws air through the open end 25<1> of the nozzle past the disk 24. The rod 8 is thereby displaced and the fuel valve 9 opened. The fuel, which enters through an exchangeable nozzle 32, is atomized by air drawn in through passages 15, 16 and variable nozzles 17, Fig. 1, and mixes with the main air passing through the perforations in the tubes 4', 56, and the air which enters past the disk 24. In modifications, the relative dispositions of the main and auxiliary nozzles in the inlet pipe may be varied.

Title: Catalytic reactor system for removing combustible products from the exhaust gases of internal combustion engines
IPC: F01N13/02
Filed: 1964-06-22
Abstract: 1,074,599. Treating exhaust gases. WALKER MANUFACTURING CO. June 22, 1964 [June 25, 1963], No. 25690/64. Heading F1B. An exhaust purifying system comprises a catalytic reactor 11, Fig. 1, in which all the exhaust gases pass through the catalyst bed 92 and upstream thereof a catalytic reactor 7 in which only a portion, or more, of the gases flow through the catalytic bed 67, the reactor 7 reducing the amount of combustible constituents in the exhaust gases to prevent overheating of the reactor 11. The catalyst is supported by perforated shells 29, 43, and some of the gases flow through a central passage 29 and an outer annular passage 53 whilst restrictions 75 in the passage 29 cause a portion of the gases to flow from passage 29 through the bed 67 to the outer passage 53 from which the gases flow to the outlet 27. The shell 43 is supported by projections 45 on the outer casing 17 which is insulated by layers 19 of asbestos and the central pipe 29 is welded at one end to a flanged member 35 and is a sliding fit at the other end in a member 35, permitting expansion. In a modification the restrictions 75 are omitted so that the gases merely flow along the sides of the catalyst bed 67 and in a further modification the outer passage 53 is omitted. In the reactor 11 the central passage 83 is closed by a plate 85 so that all of the gases flow outwardly through the bed 92 to the outlet chamber 107. The central passage 83 may taper towards the outlet end. In the reactor (161) of Fig. 4 (not shown) a portion of the gases flows straight through the central passage (169) whilst the remainder flows through apertures (171) into catalyst bed (175) and rejoins the main stream through apertures (173), a projection (177), producing a Venturi effect adjacent the apertures (173) to produce the flow through the catalyst. A multi-component system, Fig. 7 (not shown) comprises a bank of straight-through catalytic reactors 191, reactors 7, 7', similar to reactor 7 of Fig. 1, and a bank of reactors 161 as shown in Fig. 4, downstream of which is situated a flow-through reactor such as 11, Fig. 1.
