Title: Improvements in couplings for transmission of rotary motion
IPC: F16D3/00
Filed: 1944-05-25
Abstract: 581,854. Linkwork conveying rotary motion. TEAGLE, W. G. May 25, 1944, No. 10150. [Class 80 (iii)] Rotary motion is transmitted through pantograph-type linkages. One shaft b has a hub a, Fig. 4, with six projecting lugs c to receive pivot pins d equally spaced about and parallel to the shaft axis. Each pin d, Fig. 2, supports two independently rotatable collars e each having a lug e' receiving a cross-pin f for a fork g forming one of the joints or principal points of a pantograph linkage. Keyed to the adjacent end of the other shaft i is a hub h formed with six radial arms j curved over at their outer ends to present segmental plates j<1> to which is riveted a ring k having six equally spaced pivot pins l which are parallel to the axis of the shaft i and support independent collars m with wings m' receiving a cross pin n for another fork o forming a second joint of one of the pantograph linkages. Each of these linkages comprises two short links r and two long links p the latter having forks g, o for the collars l, m and being connected together by forks g<1>, o<1> to form the apex of the linkage. The two short links are connected by forks r' to mid-points p' of the links p and also by forks r<2> to a cross-pin s forming another principal point, the cross-pins s being carried by the heads t of pivot pins u upon an inner ring v of approximately half the diameter of the outer ring k. The several pivot pins u are spaced in two sets of six around the ring v with the forked connections r<2> on opposite sides alternately. The twelve linkages are arranged in two sets of six, one on the right and the other on the left hand side of the ring k, the linkages being arranged in such a way that the pair diverging from one pivot pin l connect with collars e at opposite extremities of two pivot pins d spaced at 120' on the hub a. The coupling permits of relative displacement of the shafts radially and axially and may be employed for the driving of independently sprung road wheels from a differential gearing on motor vehicles. Specification 23755/05, [Class 144], is referred to.

Title: Improvements relating to counting apparatus
Inventor: ROBINSON SYDNEY
IPC: G06M3/06
Filed: 1955-04-07
Abstract: 830,465. Electronic counting apparatus. JACKSON, S. W., ROBINSON, S., and HOWDEN, J. M., [trading as BRITISH NORTHERN ELECTRICAL APPLIANCES.]. April 9, 1956 [April 7, 1955], No. 10242/55. Class 106 (1). Apparatus for printing the amount indicated by one or more counting tubes, comprises a movable printing device associated with each tube and moved from its zero position during the application to the counting tubes of a series of pulses sufficient to step each tube through a complete cycle, the movements of the printing devices being controlled by output pulses from the counting tubes. The counting tubes may be either multi-cathode, gas-filled, or hard cathode-ray tubes. They are adapted to be connected in a chain with input to the units tube during the counting process, and to be switched for printing so that all the tubes receive, in parallel, stepping pulses which take them through a complete cycle while the printing wheels rotate from zero in the reverse direction. As each tube produces a carry pulse its associated printing wheel is released from the driving means and left in the correct position for printing the numeral indicated initially and finally by the tube. Printing may be effected in the usual manner by a hammer 35 or by spraying through a stencil. A common shaft 15 rotates all the print wheels 16 by engaging pins 17 on the shaft with pins 18 on the wheels. When an output pulse from a counting tube causes energization of a solenoid 20 the armature 21 is lifted and, rotating an arm 25, cams the printing wheel axially, releasing its pin 18 from the pin 17. The wheel is frictionally retained in position by spring means until the printing action is completed. Instead of driving several printing wheels from a common driving shaft individual step-by-step driving means adapted to be interrupted by an output pulse from an associated counting tube (Fig. 4, not shown), may be employed. If continuous counting is to be effected the pulses to be counted may be transferred to a second series of counting tubes before printing the total indicated on the first set, the reverse process taking place at the next printing operation. Printing may be initiated by pressing a button or by operation of a time switch.

Filed: 1929-04-03
Abstract: 309,047. I. G. Farbenindustrie Akt.- Ges. April 3, 1928, [Convention date]. Titanyl and titanic sulphates.-Solid watersoluble titanyl or titanic sulphates are obtained from concentrated solutions, with or without the addition of a fixing, binding or solidifying agent, by drying in a finely-divided form, e.g. by a heated current of air. The. addition of a binding agent prevents agglomeration of the dried powder. Suitable binding agents include solid absorption agents like kieselguhr, bauxite powder, asbestos powder, titanium dioxide, barium sulphate etc.; organic substances which take up water with swelling, as starch, glue etc.; and such inorganic salts or oxides as either pass readily into a modification richer in water of erytallization, e.g. sodium, potassium, aluminium or magnesium sulphates or are converted into water-soluble sulphates, e.g. magnesia, aluminium oxide &c. A superficial binding effect can also be obtained by first drying the concentrated titanium sulphate solution in a finely-divided form, and then mixing or grinding with the binding agent. Examples are given.

Title: Improvements in or relating to gramophone record playing mechanisms
IPC: G11B3/46
Filed: 1952-04-28
Abstract: 743,522. Gramophone record players. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. April 28, 1952 [April 28, 1951], No. 10636/52. Class 40(2) The two styli in a machine playing standard or microgroove records are so coupled to the speed changing mechanism that on changing the speed, the appropriate stylus is brought into position. The pressure of the pick-up and the response of the associated amplifier may also be varied. The tone arm 3, Fig. 1, mounted on the spindle 2 has a pick-up head 4 which can be rotated round spindle 5 so that either stylus 16 'for microgroove records, or stylus 17 for standard records, is in the playing position. The change over of speeds is effected by a knob 14 fitted to a spindle 12 of the gear changing device 13. The turning of knob 14 causes cable 8 to be wound on to, or unwound from, spindle 12, and causes the pick-up head 4 to swivel clockwise about the spindle 5 or allows spring 7 to swivel the head 4 anti-clockwise. A spring 15 is fixed to the spindle 2 and reduces the pick-up pressure by bearing on the wedge 9 when cable 8 is shortened on changing the speed to 45 or 33<SP>1</SP>/ 3  r.p.m. Cable 8 may also operate a switch (not shown) which adjusts the means for varying amplifier response. In a modification Fig. 3 (not shown) the tone arm support, which supports the tone arm in the inoperative position, co-operates with a lever system for changing over the pick-up head and altering the pressure of the pick-up when the change-speed knob is tuned. To prevent the changing over of the speed control during the playing of the record, a disc 32 (Fig. 5) is fitted to spindle 12, and is provided with recesses 33, corresponding to 33<SP>1</SP>/ 3 , 45 and 78 r.p.m. When the tone arm is off the rest 40, the extension 38 of lever 36 engages in these recesses under the influence of compression spring 46, thus preventing the rotation of knob 14. When the tone arm is on the rest 40, the end 39 of lever 36 is pressed down against spring 46 by the tone arm, so disengaging extension 38 from disc 32, to allow the knob 14 to be turned, if desired. The rods 41, 42 coupled to disc 32, rotate the pick-up head 4 when knob 14 is turned. Specification 678,705 is referred to. Reference has been directed by the Comptroller to Specification 698,865.
