Title: Process and apparatus for feeding pegs and the like on, for example, machines for manufacturing piano pegs or other articles
IPC: G10C9/00
Filed: 1927-01-03
Abstract: 283,340. Walle, A. Jan. 3, 1927. Feeding articles in predetermined attitude: feeding from shoots; feeding by lifting from loose assemblage in bin.-In apparatus for feeding articles such as the blanks of piano keys having one end pointed and the other end blunt to machines with the same end in advance, comprises two clamping jaws 24, 25, Fig. 4, to which the peg blanks 10 are transferred from a shoot, and which, on being moved apart, allow the blanks to fall with the blunt end in advance. The jaws are provided with similar recesses 70, 71 corresponding to the pointed end of the blanks which consequently enters the recesses to a greater extent than the other, and are mounted under the control of springs 31, 28, Fig. 1. A bell-crank lever 34 actuates the jaw 25 directly and the jaw 24 through a plate 39 which allows an adjustable amount of lost motion. The inward movement of the jaw 24 is limited by an abutment so that in the movement of the lever to the left the jaws separate and allow the pegs to fall through the slot 23. The blanks are transterned from the bottom of a shoot 8 by a member 55 which comprises a plate 52 adapted to cover the slot 23 and an overhanging arm 49 adapted to take the blanks sideways from the shoot and place them so that they are gripped by the jaws 24, 25. The, member 55 is carried by a pivoted arm 53 and is actuated by a spring and the lever 34, through a bell-crank lever 60, to produce the transfer movements. The blanks are held in the shoot 8 by a cover plate 19 and delivered one at a time by the escapement device 62 actuated by the lever 34. In the construction shown, the blanks are supplied to the shoot 8 from a hopper 5, being lifted by a scoop wheel consisting of a disc 7 with an annular flange 13 on the inside of which are projections 9 with concave ends 11. Lateral movement of the blanks in their rising movement is prevented by a segmental flange 12. The upper end of the shoot 8 is provided with a deflecting plate 14 and guide plate 15 which direct the blanks into the shoot, the end 16 of the plate 14 overlying the shoot and returning excess blanks to the hopper. The hopper is divided into two compartments 3, 4 communicating by a passage 6, the blanks being loaded into the compartment 3 and working through into the compartment by a shaking device aided by the sloping bottom of the hopper.

Title: Improvements in cryotron switching circuits
IPC: H03K3/38
Filed: 1959-01-02
Abstract: 887,654. Super-conductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 2, 1959 No. 269/59. Class 40 (9). A control conductor of a cryotron is connected in series with its own gate conductor. The control winding opposes a bias winding producing a magnetic field less than the critical field 1.HC required to make the cryotron resistive. The cryotron can then carry a current producing a field greater than 1.HC without driving itself resistive. A latch-type circuit flips over in response to an interruption on a control circuit and remains in a stable condition until re-set. A flip-flop circuit responds to pulses. Latch type circuit, Fig. 5.-With current flowing in a computer circuit 22, cryotron K5 is made resistive by a momentary setting current in control winding C5. The current from source 40 flows through cryotron K4 in which the resultant of the control current + 1.1HC in winding C4a and of a biasing current - 1.9HC in winding C4b, leaves the cryotron super-conductive. With no current in cryotron K3, the control current + 1.1HC in winding C3a drives the cryotron resistive. When circuit 22 is interrupted, K3 becomes super-conductive, the bias drives K4 resistive and the current from source 40 switches from K4 to K3. The circuit remains in this stable state when circuit 22 is again completed as the self-biasing current in winding C3b is sufficient to make the control winding C3a ineffective. Cryotron K6 enables the condition of the circuit to be detected. Flip-flop circuit, Fig. 6.-Cryotrons K7, K8 are cross-connected to form a bi-stable circuit in which the current from source 56 flows either in limb A or in limb B. A pulse supplied from source 62 to point 60 is steered by self-biasing cryotrons K10, K13 to the control windings C12, C9 of cryotrons K12, K9, whereby the superconductive circuit of the pair A, B is made resistive. The state of the circuit may be detected by means of cryotrons K11, K14. Mutual inductances 82, 84 compensate for the mutual inductance between windings C10a, C10b and between C13a, C13b. Additional cryotrons may be included in the circuit for the same purpose (Fig. 8, not shown). Specifications 862,178 and 887,652 are referred to.

Title: Speed control means for a fluid-actuated motor
IPC: F01B17/02
Filed: 1954-01-06
Abstract: 746,678. Hydraulic jacks; load-handling machines. SMALLPIECE, C. D. P. Jan. 6, 1954, No. 343/54. Class 78 (3). [Also in Group XXIX] A fluid pressure motor is moved at a substantially constant speed under all conditions of loading by a fluid pressure circuit including a pressure regulator having automatic adjusting means operating in dependence on variations in the back pressure exerted by the fluid in the motor. The invention is described in connection with a control circuit for a pneumatic ram operating a hoist in which the pressure regulator A comprises a valve 10 which is urged against a seating 12 by a spring 19, and which is opened to provide a flow of fluid from pipe 31 to the ram cylinder 45, via chamber 22, pipes 32, 38 and control valve C, at a predetermined pressure by rotation of a threaded member 25 acting on the valve through a spring 27, plate 28, diaphragm 21, plate 29 and rod 30. This causes the ram 47 to rise at a predetermined speed. When the ram is subjected to a change of load the back pressure in cylinder 45, which is communicated through pipe 48 to chamber 23, acts on diaphragm 21 and causes the valve 10 to open or close so substantially maintaining the speed of operation of ram 47 by varying the pressure of the fluid supplied thereto. The control valve C is provided with a piston 34 shaped to connect the pipe 38 to either the pipe 32 or an exhaust port 49. The apparatus is stated to be suitable for pneumatic or hydraulic actuation of single or doubleacting rams, and to be applicable to the control of hydraulic or pneumatic vane-type motors.

Abstract: 1,065,560. Packaging interactive materials. FEB (GREAT BRITAIN) Ltd. Dec. 21, 1965 [Jan. 8, 1965], No. 876/65. Heading B8C. In the packing or storing of two or more interactive materials in a single container, reaction between their interface or interfaces is reduced below that which will damage the compound when the materials are subsequently mixed, by gelling or stiffening the materials before packing. The components may be arranged in the container in vertical or horizontal layers or in concentric cylinders. When required for use, the components are mixed together by hand or mechanically in the container. Mechanical mixing devices may be a wire helix, a paddle stirrer or a metal or plastics plate which may be included in the container. In the embodiment, the components of a sealing composition, produced by the reaction between a polysulphide material and lead peroxide, are stored by dispersing the lead peroxide in dibutyl phthalate and making it into paste with bentone and acetone and other pigments. The polysulphide material is compounded with silica, titanium oxide and coated calcium carbonate and made into the second layer. In one form these materials are packed in a flexible sausage-like container and mixed by twisting or rolling it. One corner may then be cut off and the resulting material extruded. Alternatively, the contents may be extruded in the form of concentric cylinders which may be mixed in the hand.
