Title: Manipulator arrangement
IPC: B25J9/18
Filed: 1972-07-14
Abstract: 1405651 Welding by pressure UNIMATION Inc 14 July 1972 [15 July 1971] 33184/72 Heading B3R [Also in Division G3] A manipulator is programmed to move to its required operating position relative to a workpiece, whilst the workpiece is moved continuously on a conveyer. As shown the manipulator arm 1004, which carries spot welding electrodes 1030, 1032 is adjacent a continuously moving conveyer 1000 which carries workpieces 1002 on platforms 1006. The manipulator is similar to that disclosed in Specification 1,307,611 and has five retroactively controlled hydraulic movement actuators whose positional signals are derived from a digital memory whose output is read as the conveyer moves. Each conveyer platform is provided with a registration arm 1008 which engages a block 1014 through pivoted lever 1012. The block is moved from its initial position adjacent stop 1018 and thereby moves belt 1022 to drive encoder 1028. The output of encoder 1028 provides a digital signal which corresponds to workpiece position and is used to control the read-out of the manipulator digital memory. Cams 1020, 1040 ensure that pivoted lever 1008 engages and disengages block 1014 at the beginning and end of the manipulator travel. The block is returned to its initial position by torque motor 1042. The system is taught by moving the conveyer or workpiece by small increments and at each step positioning the manipulator manually and recording the positions of all the manipulator motions at that position. As shown in Fig. 2, the manipulator is moved to weld position 1104 at the second step and kept in this position for subsequent steps until the weld is completed. The arm is then moved across to the next welding position by recording its position at each conveyer step. If the arrangement falls out of synchronism an alarm circuit operates and causes all the hydraulic operating motors of the manipulator to be by-passed so that the arm becomes " limp " and can move with the workpiece. In a modification the manipulator is arranged to become limp whenever the welding electrodes are clamped to the workpiece. This arrangement is stated to reduce the number of programming stages required.

Title: Improvements in bearing vibration and noise tester
IPC: G01H3/00
Filed: 1960-10-03
Abstract: 905,357. Bearings &c. MINIATURE PRECISION BEARINGS Inc. Oct. 3, 1960 [Oct. 2, 1959], No. 33852/60. Class 12 (1). [Also in Group XXXVIII] In apparatus for testing a ball-bearing assembly a spindle 18 mates with the inner race 15 and is supported for axial movement by diaphragms 19, so that signal voltages are induced in a coil 24 attached to the spindle as it moves relative to magnet 25, the signal amplitude being proportional to the velocity of vibration of the spindle. A rotor drum 20 mates with the outer race 16 and is rotated by the action of compressed air from jets 21 around the periphery of housing 11. The rate of rotation of the drum is determined by measuring the frequency of pulses induced in a coil 27 by small permanent magnets 28 on the drum. The vibration signals from coil 24 are fed through a pre-amplifier to (a) an audioamplifier and loud-speaker, and (b) a meter amplifier, which supplies an oscilloscope and a vibration meter adapted to measure the maximum peak-to-peak vibration signal. Signals from the rotational-velocity coil 27 are fed through a pulse counter to a r.p.m. meter. The r.p.m. meter is provided with high and lowlimit switches so that when the air jets are switched on the rotor accelerates to a predetermined speed, whereupon the upper limit switch is actuated to (a) turn-off the air jets, (b) energize the vibration signal pre-amplifier, and (c) start an automatic timer. The rotor drum gradually loses speed and when the r.p.m. indicator hand touches the lower limit switch the timer is switched off, whereby an indication of the bearing friction is obtained. The vibration meter may be calibrated in units of velocity (e.g. microns/sec.) by driving spindle 18 and coil 24 with an electromagnetic system energized by A.C. of known frequency and amplitude.

Title: Improvements relating to fibre boards
IPC: D21J1/00
Filed: 1920-12-01
Abstract: 177,835. Shaw, J. K. Dec. 1, 1920. Boards; fireproof paper; paper-machines.- Fibre boards are composed of different layers of fibres, the fibres of each layer being interlaced and the fibres of one layer being interlaced with the fibres of the adjacent layers in the manner described below. One or more of the layers may be fire-proofed or waterproofed, and the outer layers may be of a higher quality fibre than the inner layers, and may differ from them in colour. The boards are made in an apparatus comprising a tank 1 and travelling foraminous belts 13, 18. A mixture of water and fibre is introduced through a channel 35 and passes on into a chamber 38 between a false bottom 3 and a partition 39. The fibres owing to the flow of the water separate, and travel parallel with each other, and strike the belt 13 end on. The movement of the belts causes the fibres as they strike it to become curved and succeeding fibres become entangled with them. Water and fibre are also introduced through a channel 45 into a chamber 48 and such fibre adheres in a similar manner to the belt 18. A third set of fibres introduced through a channel 40 into a central chamber 43 is caused to adhere to the fibres on the belts 13, 18 as they emerge through the openings 70, 71 from the chambers 38, 48. The fibres as they pass on are compressed into a board by the adjustable pressure rollers 6, 25. The heads of liquid in the channels 35, 40, 45 and the orifices 15, 29 through which the water escapes may be adjusted to minimize any flow from one chamber to another and to give the requisite flow of liquid. If more than three layers are required additional channels and chambers are provided. By using large fibres in the central channel a heat insulating board may be produced.

Abstract: 1,058,825. Electronic counters. WESTERN ELECTRIC CO. Inc. Aug. 29, 1963 [Sept. 12, 1962], No. 34170763. Heading G4A. [Also in Division H3l An electronic stepping switch circuit comprises a chain of three-electrode bi-stable semiconductor devices each having anode, cathode and control electrodes, the anodes of alternate devices being supplied with energy from differently phased conductors, the control electrode of each device except the first being connected to a potential divider fed from the cathode of the preceding device. Fig. 1 shows a chain of controlled PNPN devices 1 . . . n, alternate anodes of which are supplied with waveforms I A , I B  (Fig. 4). The circuit is initially reset so that only device 1 is conductive. At time t1 a pulse 43 on input A provides sufficient voltage across resistor 15 to trigger device 2. At time t2, input A becomes reduced to a low value 41, turning off device 1. Current 45 maintains the device 2 conductive until time t3 when the current in 2 is increased by a pulse 46, thus triggering device 3. This stepping sequence is repeated until device n is reached when device 1 may be reset by an external signal or, if n is an even number, by feedback from device n. Each device may be used to drive low impedance windings in a storage array, connected at 14. Fig. 5 shows a clock pulse distributor driven by interleaved positive pulses (Fig. 6, not shown) on inputs A and B. The input pulses are insufficiently large to trigger the devices of the anodes alone until capacitor 59 has charged sufficiently to trigger stage 1 on the control electrode. The voltage step thus developed across resistor 51 is delayed by resistor 52 and capacitor 55 so that at time t12, when the next pulse on input B arrives, stage 2 becomes triggered. The voltage developed in the common resistor 57 turns on NPN transistor 56 which short circuits capacitor 59 and prevents retriggering of stage 1 until the sequence has proceeded to stage n. Figs. 3, 8 (see Division H3) relate to circuits for generating stepped and interleaved pulse trains.

Abstract: 301,033. Thorens, H. Nov. 23, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Brakes, arrangement and disposition of; stopping.-An automatic brake or cut-out which does not requira different setting for different disc records is actuated through differential gear driven from the tone-arm and turntable and arranged so that a change in the drive from the tone-arm, releases a brake or cuts out the motor switch. A fixed plate 3, Fig. 2, below the turntable carries a pivot 7 on which is mounted a wheel 5 in frictional driving engagement by a spring 14, Fig. 4, with a disc 15 having face teeth engaging pinions 8 mounted in an arm 9, the pinions 8 also engaging with face teeth on a wheel 6. The wheel 5 is rotated by a rack 10 and link 12 from an arm moving with the tonearm, and the wheel 6 is driven through spindle 21 from. the turntable, the speeds being such that during reproduction the pinions 8 are merely rotated on their own axes. At the end of the record, the needle enters either an eccentric, groove or a circular groove and in either case produces a differential motion between the wheels 5 and 6 whereby the pinions 8 and arm 9 move round the pivot 7 so that a pin 30 on the arm releases the brake lever 24 for actuation by a spring 31. Besetting of the brake is effected by a beak 29 on the brake lever acting on the pin 30 to re-engage the arm 9 with a projection 28 on the brake lever,
