Title: Improvements in or relating to liquid fuel burners
IPC: F23D11/00
Filed: 1955-02-04
Abstract: 830,965. Liquid fuel and air supplies to burners. ASSOCIATED BRITISH COMBUSTION Ltd., and COOPER, R. B. May 4. 1956 [Feb. 4, 1955], No. 3367/55. Class 75(1) The liquid fuel feed to a sprayer burner movable into and from a firing position is from an oil supply chamber movable with the burner and having a valve controlled oil inlet and a valve controlled oil return flow outlet which are individually or simultaneously regulated to vary the ultimate flow of oil to the sprayer body together with means for varying the air inlet of the burner in proportion to the amount of oil passing to the sprayer body. As shown, the valves contained within the oil supply and return chamber 2 movable with the burner 1 further into or out of the furnace 17, are operated by separate toothed portions 6, 7 of a stationary gear rack 5 so that the gear 8 controlling the inlet valve at the end of pipe 3 moves out of engagement with the rack portion 6 when the inlet valve becomes fully open and the gear 9 controlling the outlet valve leading to the pipe 4 then becomes engaged with the rack portion 7 so that continued movement of the burner 1 into the furnace results in the flow of oil through the return valve being gradually stopped while the flow of oil through the inlet valve remains constant whereby a correspondingly increased amount of oil passes to the burner. At the same time a cowling 12 is displaced progressively over the air inlets 15, 18, of two or more air passages 13-14 and 1/13 through which air passes to the discharge end of the burner. To this end cowling 12 is fitted on two parallel bars 11 connected to a pair of bars 10 laterally extending from the chamber 2 so as to move with it to move the cowling to uncover the inlets 15, 18 in succession. The burner may be moved manually, or by a piston operated hydraulically or pneumatically.

Title: Improvements in logical switching circuits
IPC: H03K19/16
Filed: 1956-02-03
Abstract: 821,322. Saturable reactors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 3, 1956 [Feb. 8, 1955], No. 3422/56. Class 40 (9). [Also in Group XIX] A logical switching circuit comprises a magnetic core which is switched by a signal on an input winding, a clock-pulse on a read-out winding then restoring the core and developing signals on two output windings, the output signals being of opposite polarity and representing true and complemental signal values. A three-way negative OR circuit has input terminals X, Y, Z each fed by a three-terminal negative AND circuit, only one of which is shown. A negative pulse on lead 5 is amplified by transistor 3 and passes through coil 2 to switch the core 1. A subsequent clock-pulse through winding 17 restores the core and generates outputs in windings 7, 8 which appear at terminals T, C as true negative and complemental positive pulses. In Fig. 2, the input signal is applied also through a regenerative winding 20 before being applied to the transistor. The core switching time is thus reduced. The transistor is replaced in Fig. 3 by a further core 30. The input signal is applied to winding 31. The core 30 is reset by a B clock pulse on winding 34, the output signal from winding 32 being applied through a rectifier to the input winding 2 of core 1. An A clock pulse restores core 1 to produce output pulses on terminals T and C, this clock pulse being applied also to winding 35 to prevent core 30 being influenced by spurious backward signals from core 1. The circuits shown are represented schematically in Fig. 5 as a unit circuit which may be applied to more complex circuits. It may be used as a regenerative circuit, Fig. 6, with an output from terminal T, the frequency of which is determined by the frequency of the A clock pulses. Re-circulation is stopped when the switch SW is thrown. In Fig. 7 a " 1 " or " set " input is entered on one terminal 50X from unit 51 and is re-circulated from output terminal 50T to two of the terminals 50Y. The other terminal 50Y is normally negative so that the pulse from unit 51 is re-circulated by unit 50 until unit 52 registers O when a positive pulse from terminal 52C restores unit 50. Shift register, Fig. 8. Information is fed into registers 61-63 in parallel over leads 65-1 to 65-3 and is delivered in parallel over leads 66-1 to 66-3, entry taking place only when the gate-in lead 67 is pulsed. The output terminals T are connected to the input terminals of both the preceding and succeeding units so that a pulse on lead 68 or 69 provides shift to the right or left, respectively. Serial full adder, Fig. 9. Two digit registers M, N provided with automatic shift are coupled by units 70-73 in known manner to a summation register.

Filed: 1964-01-30
Abstract: 995,222. Sewing machines. DURKOPPWERKE A.G. Jan. 30,1964 [Feb.27, 1963], No. 3922/64. Heading D1G. A single-stroke compressed air motor actuating a thread-cutting knife in a sewing machine is controlled by a valve having an actuating member engaging a cam or abutment which is movable on an operating rod and which is spring-biased in the operating direction of the rod against a stop fixed on the latter. A cylinder 8, clamped to a sleeve journalling the presser bar 4 of a sewing machine, has a piston rod which carries a knife blade 11. An impulse of compressed air admitted to cylinder 8 serves to actuate knife 11 for severing the thread chain F between a pair of work pieces W1 and W2. Cylinder 8 is connected by a duct to the outlet 19 of a valve 17 having a compressed air inlet 20. Valve 17 is actuated by a linkage to which is pivoted at 36 an arm which carries a roller 18, and which is arranged to pivot clockwise, but not anticlockwise, from the vertical position shown in Fig. 3. Roller 18 normally engages a slidablymounted tubular member 26 to which is fixed one end of a rod 22. A pad 31 at the other end of rod 22 is engaged by a knee-actuated lever 32. A spring 23, disposed between a collar 24 fixed to rod 22 and a cam member 21 slidable on rod 22, biases member 21 against the inner end of member 26. On actuation of lever 32, to move members 22 and 26 inwardly against the bias of spring 28, roller 18 rides over cam 21 and engages a tubular extention 30 of the latter, whereby valve 17 is momentarily opened to actuate knife 11. On release of lever 32, roller 18 re-engages member 26. In a modification, member 26 is connected by a linkage to a treadle. In a further modification a photo-electric cell 2 is influenced by the gap between the workpieces to energize a solenoidvalve for admitting compressed air to a cylinder, the piston rod of which is rigid with member 26. The arm carrying roller 18 may be non-pivoted, whereby valve 17 is also momentarily actuated on return movement of member 26 for cutting both ends of the thread chain.
