Title: Improvements in shears for trimming thick and medium metal plates
IPC: B23D31/04
Filed: 1964-01-24
Abstract: 1,048,732. Shearing. SCHLOEMANN A.G. Jan. 24, 1964 [March 18, 1963], No. 3120/64. Heading B3W. A plate shear having one stationary blade and one movable blade in which the movable blade can be displaced from the plane of the cut during the return stroke is characterized in that the axis of rotation of the movable blade holder is parallel to the cutting edge of the movable blade and is located in the direction of cutting movement in front of the cutting edge of the movable blade. The shear comprises a frame 1 and a shaft 3 carrying an eccentric 4 which has a bearing surface 5 in the shape of a segment of a sphere. There are corresponding bearings 6 in the blade holder 2. Guide surfaces for the blade holder 2 comprise a surface 8 facing the breast 7 of the blade 13, and a surface 10 cooperating with a plate 11 on the back of the blade holder. The shaft 3 is movable axially by a piston-and-cylinder 15 and movement of the shaft in the direction of the arrow 14 results in the blade holder 2 tilting about the edge 16 of the plate 11 so that the blade 13 moves out of the cutting plane 17, Fig. 2 (not shown). The force tending to separate the cutters during the working stroke is opposed by the piston 15 and by an additional thrust obtained by using helically toothed gearing in the drive to the shaft. The side guides 20 for the movable blade are convex and engage an intermediate member 21 which has a co-operating concave face and a flat face which slides on the frame. With this arrangement the blades rock during the cut.

Title: Improvements in servo-motor control systems
Inventor: BONIKOWSKI ZBIGNIEW
IPC: H02P23/00
Filed: 1966-01-25
Abstract: 1,106,354. Control of A.C. motors. BRITISH INSULATED CALLENDER'S CABLES Ltd. 24 Jan., 1967 [25 Jan., 1966], No. 3287/66. Heading H2J. [Also in Division G3] A control signal, indicating the tension in a web or wire driven by an induction motor is derived from a potentiometer PT connected to a unit U for controlling thyristor amplifiers A1-A3 in the stator circuit. When the control signal is positive, amplifiers Al, A3 conduct in both channels, whereas, the amplifiers A2, A3 are conductive when the control signal is negative. The capacitor C has a value such that the power supply to stator windings W1-W3 is substantially balanced when the tension has an optimum value and the motor runs forward at full speed. Major variations in the tension causes a change in polarity of the control signal to reverse the torque and, possibly, the direction of rotation until, the tension is restored to its desired value. Each of the amplifiers A1-A3 comprises thyristors in inverseparallel with series diodes, the thyristors being triggered through individual transformers. Each trigger circuit G1-G3 comprises two unijunction transistors having respective base electrodes linked through positive and negative half-cycleactuated switches to a source SV of synchronizing voltage in phase with the voltage applied to the amplifier with which the circuit is associated. The other bases of the unijunction transistors are connected respectively through transistors to the primaries of the triggering transformers. When the potential at contact M is positive, a positive signal is applied through terminal IE2 of inverter and emitter follower circuit IE to terminals C2, C4 of trigger circuits G1, G3, which generate pulses in transformers TP1, TP3 and TN1, TN3. This causes both thyristors in each of the amplifiers A1, A3 to conduct during a portion of each half-cycle, equivalent to the magnitude of the signal at contact M. When the input signal is negative, trigger circuits G2, G3 are similarly energized from terminal IE1 to cause amplifiers A2; A3 to conduct. The output of a tachometer generator driven by the wire in a winding system may be fed from circuit A through stabilization network Z2 to operational ampli. fier DA which has direct feedback through R.C.-network Z3.

Title: Improvements in devices for the combustion of liquid fuel
IPC: F23C99/00
Filed: 1933-02-06
Abstract: 409,861. Oil heating-stoves; burners. KNUDSEN, A., 43, Hovitzvej, Copenhagen. Feb. 6, 1933, No. 3559. [Classes 75 (i) and 126.] An undulated filament 18 mounted in a collar 16 of porcelain or other insulating material is heated electrically to ignite and to promote the evaporation of liquid fuel at a wick 11 adjustably mounted in a reservoir 7. In Fig. 1 the wick burner is shown heating a radiator comprising a water vessel 1 having its upper and lower compartments 2, 3 connected to heat-radiating elements 4, the combustion gases being conducted through a chamber 9 and spiral pipe 10 to a chimney or to a device 31 absorbing noxious gases and solid particles. Air for combustion enters partly through the inner wick tube 12 and partly through a passage 8 above the fuel reservoir. The electric circuit to the filament 18 is completed through a thermostat 21 projecting below the water level in the vessel 1 and a switch 24 which is interrupted by a float-operated rod 23 when the reservoir 1 needs to be refilled. If the water temperature rises to a predetermined limit the thermostat 21 cuts off the current to the filament 18 thereby considerably reducing the flame. If the water temperature falls below a predetermined limit owing to lack of fuel in the reservoir, the thermostat 21 closes the circuit of an electromagnet 28 and operates a lever 29 to close a damper 25 in the pipe 10 so that the burner flame is extinguished. In Fig. 3 the burner is shown applied to a cooking stove, a conical combustion chamber 42 being arranged above the fuel reservoir in a housing 43 carrying a grating 44 supporting the cooking vessel.

Title: Improvements in or relating to burnishing machines suitable for use in the manufacture or repair of boots or shoes
IPC: A43D95/20
Filed: 1937-02-06
Abstract: 489,958. Shoe burnishing machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., andKEALL, F. B. Feb. 6, 1937, No. 3587. Addition to 454,940. [Class 17 (i)] The invention described in the parent Specification, wherein one oscillating shaft carries a burnishing tool and is also connected to a second shaft to oscillate a burnishing tool thereon, is combined with an automatic edgesetting machine of the kind described in Specifications 14696/08 and 246,213, [both in [Class 17 (i)]. The automatic machine operates around the forepart of the shoe and the other two tools comprise an oscillating disc of small size for use, at the waist and an oscillating iron of the kind described in Specification 359,973, for use at the ball portion. The three hand-feed tools are so placed that an operator standing in operating position at the automatic machine may present the shoe to each tool in succession without appreciably changing his stance. A casting 5 is secured to an automatic edge-setting machine with a driving pulley 15 at the back. The pulley drives a shaft 13 having an off-set arm having secured on it an aslant pin 21 passing through a gimbal sleeve 23 carrying a pair of pins rotatable in bearings in the upper and lower portions of a rocking casting 27, secured at its ends to coaxial shafts 29, 31 of which the second carries an edge-setting disc 33 some five-eighths of an inch in diameter, which oscillates some 2,000 times per minute through some 70 degrees. The frame 27 carries a ball 43 connected by a link 45 to a ball on an arm 41 secured to a shaft 37 carrying the oscillating iron 40, which is oscillated at twice the speed of the disc 33, since the frame 27 swings to and fro in a rising and falling arc, and at each movement in one direction imparts both a rising and falling movement to the arm 41. The shaft 13 carries a disc 49 intended to dip into oil in the casing and throw oil into a tray 51, from which a pipe 75 leads to the balls at the ends of the link 45, and another pipe to spiral grooves on the pin 21. The tool 40 may be heated by gas, as usual, but the tool 45 is heated by an electric resistance in a sleeve 81 having a shoe 83 partially surrounding the spindle carrying the tool. Conduction of heat from the sleeve 81 is minimized by providing the sleeve with protuberances 87, one of which is engaged by a screw 89. The tools 35, 40 may have devices of the kind described in Specification 456,364, [Group III], for impelling small quantities of wax against the sole edge, associated with them, these devices being controlled by a treadle.

Abstract: 621,498. Hydraulic presses; multiple-way valves. PRECISION DEVELOPMENTS CO., Ltd., BOX, F. J., and OLAH, G. Feb. 7, 1946, No. 3874. [Classes 69 (ii) and 135] Pressure liquid is exhausted from a hydraulic press &c. in two stages, first at a slow rate, during which the elastic strain in the press cylinder is relieved, and then rapidly. Fig. 2 shows a valve in which the flow from a press port 6 to an exhaust port 5 is controlled by a hand-operated piston 3 having a groove 12 connected by a radial hole 15 to a bore 13 communicating with a chamber 14 connected by a restricted passage 7, 8 to the exhaust port. In use, the valve is pushed inwards so that the groove overlaps the port 6 and liquid from the press flows into the chamber. and thence through the passage 7, 8 to the exhaust. The back pressure initially developed in the chamber arrests the movement of the piston. However, continued exhaust of liquid through the passage results in a fall in the back pressure until the inward stroke of the piston can be completed, thus permitting direct and full flow between the ports 6 and 5. Fig. 6 shows a modification in which the valve is provided with a pressure liquid supply port 18 in addition to the exhaust and press ports 5, 6 respectively. In the position shown, the ports 6, 18 are both in direct communication with the exhaust port 5 through the bore 17 and the passage 21 respectively.
