Title: Improvements in a method of metal drilling by a metal-drilling or like machine
IPC: B23B47/34
Filed: 1959-07-20
Abstract: 872,617. Drilling and tapping machine details. WALSH, R. W. July 20, 1959 [Oct. 23, 1958], No. 24816/59. Class 83 (3). In a drilling, tapping, &c. machine, the tool is driven through a yielding- coupling which slips continuously during the cutting operation and is given rotational impulses so that the cuttings removed are flaky or powdery and the tool breaks through without leaving a burr on the work. Heating of the tool is also said to be reduced. The machine comprises a column 10, Fig. 1, supporting a vertically-adjustable work-table 11 and a drilling-head 14 having a motor 17 which drives the spindle 21 through a belt 20 and pulleys 19, 22, the pulley 22 being splined to the spindle 21. The spindle 21, Fig. 3, drives a spindle 48 through a fluid coupling 54 which includes a top and bottom housing 55, 56 secured together by screws 57, and secured to the spindle 48 by screws 58. A rotor 59 in the coupling 43 has an integral shaft 62 which is connected to the shaft 21 through flanges 67, 68 and pins 70. The spindles 21, 48 are supported by a bracket 45 which moves vertically with the spindles during feeding of the tool, which may be manually by rack and pinion 25, 27 or by a split-nut 41 engaging a screw 38 rotated by a worm and wheel 39, 37 driven from a motor 35 and a variable speed transmission box 34. In operation the spindle 21 is rotated at constant speed, to drive the rotor 59, and the housings 55, 56 connected to the spindle 48 at 51 being driven at a reduced speed due to slipping between the rotor and the housings, the amount of slipping depending on the quantity of fluid in the spaces 73, 60. The housing 55, and the rotor 59 have vanes 72, which when the fluid passes during differential rotation of the two parts produces pulsing of the spindle 48. In a modification, pulsing is produced by an airjet which engages vanes on the housing. In a further modification, pulsing is produced by intermittently restraining the spindle 48, Figs. 6, 8, by pistons 82, in a non-rotary member 79, fluid-pressure being supplied to the pistons through a conduit 86. The inner ends of the pistons engage a sleeve 96 having a cam 97 and as the spindle rotates the cam intermittently moves each piston against the fluid pressure.

Title: Induction type electricity meters
IPC: G01R11/20
Filed: 1975-05-23
Abstract: 1464995 Induction meters GENERAL ELECTRIC CO Ltd 23 May 1975 [5 June 1974] 24893/74 Heading G1U A three phase induction meter has three driving elements, each with voltage and current drive windings, and a single rotor disc, and for at least two of the elements, the phase voltage is applied across the voltage drive winding in series with an auxiliary winding which is itself inductively coupled to another drive winding. As shown in Fig. 2, one drive winding WA is wound in the opposite sense to the other two W B , W C . Since each phase voltage (across e.g. terminals N and TA), is the vector sum of the voltages across the windings W A , W A1 , the drive winding voltage is shifted by a small amount from the phase voltage depending on the magnitude and phase of the auxiliary winding voltage. By connecting the senses of the auxiliary windings as shown, the correct phase compensation is achieved whichever order the phases are connected to T A , T B , T C  i.e. R-B-Y or R-Y-B. Figs. 4a and 4b (not shown). In a modification Figs. 3, 5a, 5b (not shown), the auxiliary windings in series with W B , W C  are both inductively coupled to the winding W A .

Title: Device for feeding work pieces for processing
IPC: B65H5/16
Filed: 1959-07-25
Abstract: 892,991. Feeding sheets. SCARRONE, A. R. Sept. 12, 1960 [July 25, 1959], No. 25591/59. Class 100(1) [Also in Group XXX] A device for feeding work pieces in sheet form to a machine for processing the work pieces comprises a jib 3 which is pivoted at 4 to a frame member 2 and includes a circulatory chain conveyer. The ends of the conveyer wrap sprocket wheels 6, 7 and the chains are guided by sprocket wheels 8. Pins 9 project from the chains and entrain work pieces which are stacked on a table 25. The jib may be raised on its pivot 4 by operation of a solenoid 14 the armature of which is coupled to a bar 11 mounted on the jib. Slipper bars 18 are adjustably supported on the jib such that the pins 9 project a predetermined distance beyond the bars 18. Disengaging bars 20 are fixed to the frame member 2. Feelers 21, 22 are engageable with the under surface of a work piece being fed through by the conveyer and, through switches 23, 24, control energization of the solenoid 14. The table 25 is vertically movable in guideways 26 by sprockets and chains, the sprockets at the upper end of the guideways being rotatable by ratchet and pawl means 28, 29 operable by a connecting rod 34 driven off a shaft 36. A solenoid 33 is normally energized and causes a bar 31 to hold the pawl 29 clear of the ratchet 28, but when a feeler 40 swings downwardly as work pieces are withdrawn from the pile on the table 25, the solenoid 33 is de-energized and the pawl engages the ratchet. The shaft 27 is thus rotated unidirectionally and the table is raised. In operation, the pins 9 project into the topmost work piece on the table 25 and drag it off the pile. As the work piece moves through the device, the leading edge of the work piece actuates the feeler 21, the solenoid is energized and the jib is lifted thus preventing a second work peice from being removed from the pile. As the first work piece continues to be carried forward, the disengaging bars 20 press the work piece clear of the pins, the trailing end of the work piece clears the feeler 22 and the solenoid 14 is de-energized to allow the jib 3 to drop. The next work piece on the pile is then engaged by the pins. When the device is to operate with a bag making machine in which each work piece consists of a piece of fabric folded double, a bristle roller lifts the top layer of the work piece clear of the lower layer so that the work piece may be fed on to a guide bar which passes between the two layers. Specification 864,364 is referred to.
