Title: Improvements in or relating to automatic lathes
IPC: B23B7/14
Filed: 1922-05-03
Abstract: 202,249. Bright, F. E. May 3, 1922. Lathes; chucks.-An automatic chucking lathe has means for holding the work, such as the casing ring of an antifriction bearing, with two side faces and a circumferential face entirely exposed for machining, a transverse slide carrying two tools for cutting the side faces, a third tool to cut the circumferential face, and actuating-mechanism common to all three tools. The lathe comprises a frame in which is :mounted a hollow spindle 11 containing an axially-movable plunger having inclined grooves 5f, Fig. 9, for actuating the jaws of the chuck 5 which slide in radial slots and are adapted for internally gripping the work, such as a ring A. The spindle is driven from cone pulleys on a shaft 14 and worm gear 12, the pulleys being connected to the shaft through a clutch 18, handoperated by a lever 18a and disengaged after a cycle of operations has been completed by a pivoted trigger 61 on a cam 55. The cam shaft 31 is driven from the spindle through worm gears 43, 32 and a shaft 34 mounted in a bracket 37, which is capable of being swung about the axis of the cam shaft and is yieldingly held to the frame by bolts 38, 39 and arcuate slots, so that the worm drive will become disengaged if excessive pressure is put on the tools. A hand-wheel 65 is provided on the shaft 34 for moving the tools when the worm drive is disengaged. The adjustable connection of the bracket also allows the gear ratio of the cam-shaft drive to be changed. A tool 10 for turning the periphery of the work is mounted in a holder 45 carried by a bar 44 which is longitudinally slidable by means of a cam 55, lever 58, and adjustable collars 60. Two other tool-holders 7a, 8<a> are adjustably mounted on a transverse slide 6, reciprocated by a lever 24 and cam 30, the slide also carrying a cam 47 which supports an arm 46 on the tool-holder 45 in two positions, the portion 47<a> presenting the tool 10 in a cutting position and the portion 47<b> lifting the tool clear of the work. In operation, the driving-connections are so timed that the slide 6 moves to the right in Fig. 1 and a roughing-tool 7 acts on an end face of the work while the tool 10 is traversed bv the cam 55. On reversal of the slide, a finishing- tool 8 acts in place of the tool 7, and the cam 47 lifts the tool 10, which is then withdrawn. Additional roughing and finishing tools, such as 7<x>, Fig. 2, may be provided on the slide for machining the rear face of the work, and the tools may be changed so as to perform such operations as roughing, grooving, chamfering, finishing, &c., either singly or collectively. Specifications 24062/95 and 26167/08 are referred to.

Title: Data transmission systems
IPC: G06F1/02
Filed: 1963-12-02
Abstract: 1009493 Telegraphy; pulse modulation systems INTERNATIONAL BUSINESS MACHINES CORPORATION 2 Dec 1963 [18 Dec 1962] 15382/65 Divided out of 1009492 Headings H3H H2A H3A H3D H23D H6A16B H6D H7B H7F H8B H13D H14D and HE The claims relate to a waveform generator comprising a parallel arrangement of digital to analog converters. As described, the generator is used in a data transmission system in which data pulses are so modified by the generator before transmission that the resultant waveforms, being distorted by the transmission path, are received as square pulses. In a first embodiment a test pulse A is sent over the transmission path. It is received distorted as at B. This signal is sampled at bit rate, and the samples converted to digital signals which are transmitted at low speed to the main transmitter. The digitized samples, four 5-bit signals as shown, are stored in shift register 36, the sections of the register controlling switches in respective digital to analog converters 32. The switches put in circuit binary-weighted resistors 40 and control the sign of the analog value. Data from 52 feeds shift register 38. The presence of a 1-bit in Sl causes the value held by the first converter 32 to be read out to summing amplifiers 34. This 1-bit progresses at bit rate through register 38 so that a waveform D appears at the summing amplifiers' output. This is waveform C time-reversed. After smoothing waveform E is transmitted the transmission path so distorting this that a substantially square signal of 1-bit duration is received at 19. Subsequent bits from 52 will cause a summation  of linearly displaced waveforms D, giving a waveform F, for example; Fig. 2. In a second embodiment the distorted test pulse is sampled at a rate higher than bit rate; in this case each section of register 38 controls more than one digital to analog converter, these converters being enabled in succession at the higher sampling rate. A system using a 4-level data source is described. The four levels are each regarded as two simultaneous bits which control separate registers and converters, the outputs being summed before transmission.

Title: Artificial honeycomb
IPC: B31D3/02
Filed: 1928-05-25
Abstract: 312,801. Bonalda, A. May 25, 1928. Pleating.-An artificial honeycomb made up of strips of flexible material such as cellulose, paper, parchment paper, or wood veneer corrugated to form a succession of troughs 2 of semi-hexagonal shape and gummed together has the axes of the hexagonal tubes thus formed set at an angle of about 10‹ to the faces of the comb. To corrugate the material, it is pressed into semihexagonal troughs formed by two sets of hexagonal mandrels 4, 5, staggered relatively to each other, by wheels 7 having projections 8 of semi-hexagonal shape. The wheels 7 are carried by a rack 15 driven alternately forwards and backwards through connections from a power pulley 22. This pulley also transmits motion to a shaft 28 driving, through worm gear 29, 30, shafts 31 carrying cam drums 32, 33. The drum 32 actuates a lever 42 connected to a rod 45 operating toggle levers 50 -- 53 by which the mandrels 4, 5, are moved towards and away from each other. The drum 33 gives a lateral movement to the mandrel-carrying carriage after each length of strip has been corrugated. The material may be in cut lengths, or it may be supplied from a brake-loaded roll 12 and folded back to form successive lengths of corrugated strip. The first length of material is corrugated by being depressed into a supporting plate 63, which is thereafter lowered the required distance as each fresh length is corrugated on the mandrels.

Title: Improvements in automatic chain welding machines
IPC: B21L3/02
Filed: 1949-06-09
Abstract: 683,806. Welding by pressure. ESSER, P., (trading as MEYER, ROTH & PASTOR). June 9, 1949 [March 30, 1949], No. 16401/49. Class 83 (iv). In automatic chain welding machines, safety means which cause the machine to be stopped when one of the holding members does not assume its correct lower position, are actuated by a holding member moving in the same direction as the chain feed. The chain 11 is pulled from the left on rails 12 until the upright link to be welded advances to a platform 13 and abuts against the right-hand holding member 14 which has been lowered first. The left-hand member 15 is lowered and both members 14, 15 move towards one another to apply pressure to the link ends. The electrodes 16 are lowered to embrace the link and the circuit is switched on. A short final pressure by the members 14, 15 is applied. The electrodes 16 are lifted and two swaging jaws are applied to the joint and are then withdrawn. The members 14, 15 are withdrawn and raised to clear the chain which feed is recommenced. An abutment 18 on the member 15 moves above to clear the contact pin 20 of a switch 19 when the member 15 assumes its correct position (Fig. 1), but if the link assumes an inclined position on the platform 13 the member 15 cannot be lowered to its correct position so that it slides over the link and causes the abutment 18 to engage the contact pin 20 of the switch 19 to cut the supply to the motor and so stop the machine. In the making of short chain lengths, the link which is not to be welded reaches the platform 13 and the member 15 is held up, the welding current is switched off and the member 15 moves forward with the abutment 18 moving below and clear of the contact pin 20 of the switch 19. The cut-out device may be actuated mechanically, electrically, hydraulically, pneumatically or an optical device using a photo-cell may be employed.
