Title: Electronically controlled automatic machine tools
Inventor: NAMENYI-KATZ LASZLO
IPC: B24B49/00
Filed: 1961-01-27
Abstract: 932,069. Machine tool details. VECTRON ELECTRO PHYSICS Ltd. Jan. 24, 1962 [Jan. 27, 1961], No. 3309/61. Class 83 (3). [Also in Group XXIII] A system for controlling the distance moved by a tool in a turning, grinding, milling or drilling machine comprises a tool feed mechanism, a counting device coupled with the tool and with the feed mechanism, a sensing device normally positioned in the path of the tool having a face set at a known distance from the work, the sensing device being coupled to the counting device and serving on engagement with the tool to initiate counting, and the feedmechanism being adapted to stop the tool after a predetermined count. A workpiece 1 is held in a lathe and the tool slide 5 is moved by a feed mechanism FM. A metal strip 15 fixed to slide 5 rotates a roller 17 secured to a glass or other transparent disc 21 so that as slide 5 moves, a light 23 shines through apertures in disc 21 to supply pulses of light to a photosensitive device 24. A piezo-electric crystal 7 is mounted in a pivotable holder 8, the face 11 of the crystal being set at a known distance from workpiece 1. In operation, crystal 7 is oscillated by a circuit OSC, preferably at a resonance frequency and is connected to an amplifier circuit AMP1. The output from AMP1 is fed to a gate G coupled to a counting circuit CC, and the gate is also connected to device 24. When tool 4 contacts surface 11 a signal from amplifier AMP1 opens gate G and allows the pulses from device 24 to be fed to the counting circuit CC to initiate a count. A solenoid circuit SOC energizes a solenoid 12 to pivot crystal 7 away from the tool and after tool 4 has moved the required distance a signal is fed to mechanism FM to stop or retract the tool. A further piezo-electric crystal 26 mounted on slide 5 may be provided and is connected to an amplifier AMP2 which is coupled to a bistable multi-vibrator BMV which in turn is coupled to feed mechanism FM. Amplifier AMP2 detects surges in the output from crystal 26 when the tool engages the work and feeds a signal to BMV which in turn feeds a signal to mechanism FM to slow down the feed.

Title: Device for Assisting in the Manipulation of Appurtenances, Controls or the like Associated with Sewing Machines
IPC: D05B29/02
Filed: 1967-01-23
Abstract: 1,164,502. Sewing machines. SINGER CO. 23 Jan., 1967 [7 Feb., 1966], No. 3311/67. Heading D1G. Means for assisting in the manipulation of an appurtenance shiftably, supported on a sewing machine and operatively connected to an operator-influenced linkage, comprises valve means carried by said linkage, means for providing a predetermined amount of lost motion in said linkage to operate the valve means, a fluid pressure-operated drive member operatively connected to the appurtenance, .and conduit means interconnecting the drive means and valve means with a source of fluid under regulated pressure. As shown, a presser bar 14, carrying a presser foot 13, is operatively connected to one end 20 of a lever 21. End 20 may be raised by a hand-operable lever 23 to lift the presser foot against the bias of a spring 15. The other end 26 of lever 21 is connected by a pull rod 28 to one arm of a lever 31 pivoted on a bracket 33 within a lubricant collecting pan 12. The other arm of lever 31 is connected by a push rod 35 to an arm 39 pivoted on a bracket 37 depending from pan 12. A depending rod 40, rigid with arm 39, passes through a bore in a block 50, the latter being adjustably secured to rod 40 by a screw 71. A slot in block 50 houses a valve (51) secured in position by screws 73. The inlet of valve (51) is connected by a conduit 52 to a pressure-regulating valve 53. The outlet of valve (51) is connected by a conduit 54 to a cylinder 55, the piston rod 58 of which carries a stop nut 60 bearing downwardly on end 26. A resilient knee pad 41 is fixed to a plate 81 slidably mounted on studs 84 projecting from block 50. A compression spring 85, housed in block 50, abuts at one end against screw 87 and at the other end against plate 81 to bias the latter against the heads of studs 84. Knee pressure on pad 41 thereby serves initially to shift plate 81 along studs 84 for actuating the operating plunger 76 of valve (51). Air is then admitted to cylinder 55, the pressure being so regulated by valve 53 that the downward force exerted on end 26 by nut 60 overcomes about 80 per cent of the force of spring 15. Comparatively little additional force on pad 41 is therefore required to raise the presser foot via the pull rod 28. Valve (51) is arranged to exhaust the air from cylinder 55 on release of pad 41.

Abstract: 575,049. Casting-machines. ROSSI, I. Feb. 23, 1944, No. 3358.. Convention date, Oct. 21, 1942. [Class 83 (i)] Moulds.-A continuous casting machine has a mould 1 surrounded by a water-jacket 7, a second waterjacket 21 below the first to apply water directly to the casting c, and means for rotating the water in the second jacket. Cooling water from a pipe 8 enters the jacket 7 through 'an annular chamber 4, pipes 9, an annular chamber 6, and inclined slots 11, Fig. 3, and is discharged through a space 13 into a chamber 5 whence overflow pipes 14 carry it to nozzles 15 arranged tangentially to the casting, causing the water in the jacket 21 to rotate. The length of the discharge pipes 28 may be varied to vary the level of the water in the jacket 21 or even to force the water between the casting c and the mould. This may have inclined grooves externally to increase heat transfer and, in co-operation with the rotary movement of the water in the jacket 7, throw the hottest water through the space 13. The jacket 21 may be removably supported by studs 33 and have packing 32, 37 to make tight joints with the chamber 5 and casting c respectively. The mould 1 may be reciprocated vertically in known manner, e.g. as described in Specification 437,064 or be stationary.

Title: Dielectric Testing
Inventor: HYDE PETER JOHN
IPC: G01R31/02
Filed: 1967-01-23
Abstract: 1,169,243. Insulation testing. IMPERIAL CHEMICAL INDUSTRIES Ltd. Jan. 10, 1968 [Jan.23, 1967], No.3363/67. Heading G1U. A dielectric specimen, which may be the insulation of a wire or a continuous insulating sheet, is tested while moving continuously by a method wherein the applied voltage is reduced to zero immediately a fault is detected. A linearly increasing A.C. voltage produced by modulating the output from a ramp generator is applied across the specimen as it passes through a test cell. When a discharge is detected in a resonant circuit coupled to the cell, a pulse is produced which triggers a multi-vibrator to consequently reset the ramp generator to zero, after which time the ramp generator output voltage starts to rise again. The maximum values reached by the ramp are recorded. The system is suitable for on line testing as coated wire is manufactured using an A.C. frequency of 1000 cps., and responds to discharges of 10<SP>-12</SP> coulomb, so avoiding a large discharge passing through the insulation when a fault is detected, so that no burning out occurs. A suitable test cell for the cable test incorporates a water filled cavity (1, Fig.3) through which the cable passes via rubber sealing diaphragms (3) held in place by nylon bolts (4) having central holes for the passage of the cable. The test potential is applied to the water filled cavity, while the cable core is connected to earth through an inductor, which together with the stray capacitance forms the required resonant circuit. A good specimen will show a record of discharge inception voltages (D.I.V.) which are uniformly high-faults will be shown by D.I.V.'s appearing in the record.
