Abstract: 900,965. Winding reserve coils on wound cops. REINERS, W. Sept. 24, 1958 [Sept. 30, 1957], No. 30499/58. Addition to 874,844. Class 120 (2). The apparatus claimed in claim 19 of the parent Specification is modified by replacing the conveyer supplying the cops by a transportable receptaole 201 having a discharge opening through which the cops are removed one at a time by a device projectable into said opening and operating in timed relation to the rotation of the turret. The device may take the form of toothed wheels 204 driven by chain and sprocket from the shaft of the turret. The teeth enter the receptacle through slots in its base and the cops fall into the spaces between the teeth by an opening in the side wall of the receptacle, which is normally obtruded by a bar movable in slots in the side-walls of the receptacle, but which is raised to release a cop by the teeth and the cop itself. The receptacle is supported by a member 208 secured to the machine-frame and terminating in an arcuate part extending around the wheels. The rest of the apparatus is generally similar to that of Fig. 8 of the parent Specification.

Abstract: 627,595. Hydraulic accumulators. CONWAY, H. G. Oct. 21, 1946, No. 31286. [Class 69 (ii)] In a hydraulic pressure supply system including a pump 20 and a hydro-pneumatic accumulator 11, a valve 15 is arranged to isolate the accumulator from a system 126 when the level in the accumulator falls below a predetermined level, leaving the pump to supply the system only. The valve 15 is contained in a cylindrical casing 14 having a port 31 connected to the pump 20 and communicating with an annular recess 21 in the valve 15 when the latter is in its upper position and so through bores 22, 23 with the accumulator 11. The accumulator contains a free piston 12 which in its lowest position contacts the valve 15 and moves it downwards so that the recess 21 is isolated from the port 31. The accumulator is connected through a non-return valve 24 with the system 126, which is also connected to the pump through a pipe 26. A valve 29 set to operate at the maximum accumulator pressure is connected between the system 126 and a valve 17 which resets the valve 15 to put the recess 21 in communication with the port 31 to recharge the accumulator. Between the valves 29 and 17 a leak-valve 32 is provided to the sump 30.

Abstract: 892,467. Boring and turning mill details. AMERICAN STEEL FOUNDRIES. Oct. 1, 1958 [Oct. 22, 1957], No. 31374/58. Class 83 (3). A power indexing and clamping arrangement for the tool-block 34, Fig. 1, of a boring and turning mill ram 12 is slidably and rotatably supported on a shaft 14 extending at right angles to the ram. The outside bearing for the tool-block is carried by a steady bracket 18 which also houses a pair of cam rings 76, 78. One of these cam rings is stationary and the other keyed to the shaft 14 so that as this rotates the tool block is alternately moved to and fro along the shaft to open and close the indexing and clamping rings 42, 50. The opening movement is effected by spring-pressed plungers 68. A two-part drive shaft 102 is rotated through worm-gearing from an electric motor 80 and carries a cam-disc 110 at one end to operate a switch 116 to stop the motor after one revolution. The other end of the drive shaft rotates the shaft 14 through bevel gearing and also drives an auxiliary shaft 150. The latter carries a " mutilated " pinion 160, Fig. 4, which gears with a " mutilated " wheel 164 coaxial with and secured to the tool-block 34. The gear ratios are arranged so that the toolblock is unclamped, indexed and clamped in a complete revolution of the drive shaft 102.

Abstract: 960,781. Transistor oscillating circuits. MARCONI CO. Ltd. May 20, 1963 [Aug. 16, 1962], No. 31473/62. Heading H3T. In a transistor multivibrator relaxation oscillator each of the interstage coupling circuits includes two parallel circuits each of which comprises a unilaterally conductive device in series with a capacitor. By varying with respect to one another the potentials to which the unilaterally conductive devices in the two parallel circuits are returned the proportional effect of the individual condensers in the two circuits is varied and hence the frequency of oscillation is changed. With reference to the Figure a transistor multivibrator comprises two transistors T1, T2 having their collectors and bases cross-coupled by diodes 1D1, 1D2, 2D1, 2D2 and capacitors 1C1, 2C1, 1C2, 2C2 connected as shown. Capacitors 2C1 and 2C2 are the same size and greater than 1C2 which is the same size as 1C1. The cathodes of diodes 1D1, 1D2 are returned through resistors 1RA1 and 1RA2 respectively to the H.T. line and the cathodes of diodes 2D1, 2D2 are returned through resistors 2RA1, 2RA2 to a slider P on a resistance forming part of a potentiometer across the H.T. supply. By varying the position of slider P the potential across the diodes 2D1, 2D2 is varied and hence also the effect of the capacitors 2C1, 2C2 in the cross-coupling so that the frequency of oscillations of the multivibrator may be varied.

A motorized wheel-chair has left and right hand wheels 1, 2 independently driven by respective electric motors 3, 4 which are controlled through flexible control-transmitting means extending to the head region of an occupant sitting in the chair so as to be selectively operable by an occupant who is paralysed from the neck downwards. In Fig. 1 a multiple-core electric cable 8 extends from a plug and socket connection 7 with a relay control box 6 for the motors 3, 4 to a control device actuated by a movable headrest 10. The headrest 10 is flexibly connected by a damping spring 16 to a movable front plate 13 which is connected by a ball and socket joint 12 to a fixed back plate 9 and is resiliently urged into parallelism with the back plate by a spring 14. Four switches are mounted at 90-degree intervals around the back plate 9 for actuation by the front plate 13 and are so arranged that upward tilting of the headrest 10 caused forward drive of the chair by both motors 3, 4, downward tilting causes rearward drive by both motors, and tilting to the left or right turns the chair in the corresponding direction by simultaneous forward and rearward operation of the respective motors. The switches may be micro-switches 17 or may be reed switches 18 each comprising a pair of contacts within a glass tube, one of the contacts being mounted on a flexible reed so as to be actuable from outside the tube by a magnet 19. In an alternative arrangement, Fig. 3 (not shown), the cable 8 is connected to a control device comprising four reed switches which are carried by a flexible collar encircling the occupants neck and arranged for actuation by tilting the head. In Fig. 4, operation of the motors is controlled by diaphragm-actuated switches 30 from which flexible tubes 32 extend into the occupants mouth. The switches 30 are actuated by sucking or blowing into the tubes 32 operation of one motor only when turning being effected by blocking the end of one tube with the tongue. Saliva traps 33 in the tubes 32 are suspended from the occupants neck by a cord 34.

Class 38(5) [Also in Group XIX] In a device for indicating the speed of a rotatable shaft means are also provided for indicating the direction of rotation of the shaft. Two inner ball-bearing races 3, 4, Fig. 2, are slidably mounted on the reduced end 2 of the shaft 1, the speed and direction of rotation of which is to be indicated. The outer races are located in an annular member 5 against an internal rim 6 by a compression spring 7 adjustable by a nut 9 on a screw 8. Rotation of the shaft 1 causes an arm 11 of the member 5 to close one or other of the switches 12, 13, Fig. 1, in accordance with the direction of rotation, the arm 11 then being arrested by a fixed stop 14. In another embodiment a ball thrust bearing comprising two rings 15, 16 outer races 17, 18 and a central ring 19 having a forked extension 20, 21 which cooperates with the contact lever 22 of a reversible switch, is used.
