Title: Wire printer
IPC: B41J2/24
Filed: 1955-10-10
Abstract: 785,661. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 10, 1955 [Oct. 13, 1954], No. 28799/55. Class 100 (4) A wire-printer having a number of printing heads 38 spaced several columns apart has mechanism for simultaneously moving the printing heads laterally of a platen to enable successive printing in successive character positions. As shown, the mechanism is applied to an interpreter in which electrical contact brushes B sense perforations in a punched card 44. There is one column of brushes for each printing head 38 and these are laterally moved with the printing heads. The sensing of perforations operates relays A-F and. in manner described in Specification 763,407, a control bar 24 is longitudinally and rotatively set by setting levers 28 to selectively displace the wire elements 16a of the printing heads. These are mounted between spaced plates 40a, 40b, which are moved towards the platen CP by cams 46. to effect printing, after which a follower 49b reaches the first rise in a stepped cam 51 which pivots a crank 49 drawing rightwardly a link 48 whose upwardly extending arm 48a carries a stud 50 to laterally shift the printing heads 38 and the brushes B to the next column. If required, duplicate printing may occur on the end of the card by a printing head 38d which is character spaced by the linkage 64, 62, 66 from the crank 49 and impression is effected here by a cam 60. The setting of the printing wires for duplicate printing is obtained by interconnecting character. setting levers 28 by a strap 54 so that both control rods 24 are simultaneously set. The mechanism may be applied to a four-line address label printing arrangement, the labels being in the form of a web moved in increments to present successive labels to the printing mechanism.

Title: Improvements in or relating to motor cultivators
IPC: A01B69/00
Filed: 1937-10-22
Abstract: 485,537. Implements for working land. CATCHPOLE, W. M. Oct. 22, 1937, No. 28916. [Class 6 (i)] An implement comprising a cultivator pivoted to a two-wheeled motor tractor is provided with a steering handle, lateral movement of which moves the cultivator and tractor as a whole while a rotary movement moves the tractor independently of the cultivator. The two movements can be combined to move the tractor and cultivator simultaneously. The implement shown in Fig. 1 comprises a motor tractor 1 to which is pivoted a forked bar 2 carrying a tool bar 3 fitted with ground wheels 4. An arm 5 is rigidly attached to the tractor and carries a cross-bar 6 which rests on a roller 7 projecting from a frame 8 carried by the forked bar 2. A steering shaft 11 having handle bars 12 passes through a bearing 10 in the frame 8 and is mounted at its further end in a bearing 9 on the bar 2. Fast on the shaft 11 is a sector 13 formed with two grooves in which are anchored the ends of two flexible cables 16, 17 attached at their other ends to the bar 6. The implement is guided as a whole by giving the handle bars 12 a simple movement of translation without rotation. If the handle bars 12 are given a simple rotary movement the sector 13 is rotated thus causing the bar 6. and arm 5 to move to one side and so guide the tractor independently of the cultivator tools carried by the bar 3. The handle bars can also be given a combined rotary and translatory movement to guide the tractor and tool bar simultaneously.

Refrigerating, absorption machines for. - In apparatus wherein the rectifier is cooled by evaporating refrigerant, as described in Specifications 274,340 and 282,771, the refrigerant for this cooling is taken from a point intermediate the ends of the condenser, and vapour of refrigerant produced in the rectifier cooling- chamber passes into the second part of the condenser together with the main stream of refrigerant vapour not yet condensed. In the example shown in Fig. 2 the rectifier is formed in the expulsion pipe 6 fitted with baffles 8, and is surrounded by a chamber 5 which is supplied with refrigerant condensed in the first part of the condenser 7 through a pipe 17 of sufficiently large bore to allow simultaneous inflow of condensate and outflow of vapour. The second part of the condenser is connected with the evaporator 10. A modification is described in which the chamber 5 is connected by separate openings with the first and second parts of the condenser and forms a sump between the parts. This arrangement is described in connection with the known continuous-cycle inert gas system.

As shown, a housing 1 has mounted therein a member 7 having teeth on a ring 6 urged by a spring 11 into engagement with teeth on a ring 6a attached to a part 5 carrying a drill steel in a socket 3, the part 5 being driven by a shaft 8 on which the member 7 is slidable. As the member 5 rotates the part 7 is moved by the sliding action of the teeth, against the spring 11 and as the points of the teeth pass over each other the part 7 moves by the spring action and strikes a blow on the part 5. The member 7 may be mounted in leaf springs 12 for limited rotary movement. If an air motor is employed exhaust air carrying with it some oil may be used to cool and lubricate the teeth. The slope of either side of the teeth may be different.

Title: Improvements in or relating to electric communication cable
IPC: H01B13/02
Filed: 1947-11-14
Abstract: 629,740. Cable-making machines. STANDARD TELEPHONES & CABLES, Ltd., and PHEAZEY, J. R. Nov. 14, 1947, No. 30271. [Class 36] A cable is made by drawing pairs or quads of insulated conductors from reels on a stationary framework and passing them through separate holes in a lay plate which is oscillated about its centre. As the wires emerge from the plate they are bound together to preserve their relative positions and taken up on a rotating capstan. The bundle of wires so formed may form a complete cable or it may form a unit to be twisted with similar units to form a cable. To make a layer-type cable a lay plate may be provided for each layer, the oscillations of the plates being synchronized to impart an out-ofphase looping to the wires in successive layers. In the case of a unit-type cable only one lay plate oscillating through 180 degrees in each direction is used. If the separate strands consist of coaxial cores the lay plate is oscillated through 360 degrees in each direction. Fig. 1 shows a machine for carrying out the process in which twisted pairs of wires 3 are drawn from reels 1 and pass over guides 4 and pulleys 5 and through holes in an oscillating lay plate 7. The bundle of wires then passes through a die and holder 8 and past a binding head 9 where a binding is applied to hold the pairs in position. The bound unit passes a measuring-wheel 13 and over a capstan 10, and is taken up, on a reel 11. Figs. 2 and 3 show devices for oscillating the lay plate through 180 degrees or 360 degrees. A driven shaft 14 drives a shaft 18 carrying a reversing dog 23 which clutches either of two bevel-wheels 19, 20 which engage a wheel 21 fixed to a shaft 22. The latter carries a wheel 24 which meshes with a wheel 25 engaging a toothed ring 26 to which the lay plate 7 is fixed. The lay plate 7 is thus rotated in one direction or the other according to which wheel 19, 20 is engaged by the dog 23. Movement of the dog is produced by pins 30, 31 on the plate 7. As the plate rotates the pins alternately strike the end 29 .of a bell-crank lever, the lower arm 27 of which actuates the dog. The angle through which the plate oscillates depends upon the relative positions of the pins. If only one pin is provided the plate oscillates through 360 degrees in both directions.
