Abstract: 1414027 Conveyers BUNDY CORP 21 Nov 1973 [4 Dec 1972] 54082/73 Heading B8A [Also in Division B3] Tube fabricating apparatus comprises a number of work stations each having a tube clamp, transfer means for successively advancing tubes between the work stations including clamps operable to support tubes during their transfer to or from a work station, and means to prevent disengagement of the transfer clamps until the tubes supported thereby have been gripped by the clamps of the work stations. Fig. 3 shows in plan the first half of the apparatus, being work stations 5-10, where fittings are placed on the tubes and the tube ends flared. Tubes cut to length are supplied longitudinally to a rotary feed device 74 whence tubes are taken one at a time by the first transfer device 44. Two of these are shown in side elevation in Fig. 7, each comprising a shaft 45 with arms 46 and clamps 47, rotatable through 180 degrees by rack portion 48. Each work station has fixed clamps 36. During an operating cycle, a tube held at a work station (or on feed 74) is gripped by clamps 47, the clamps at that work station are released, the shaft 45 is rotated through 180 degrees to present the tube to the next work station, or to a stacking conveyer at the end of the apparatus, the clamps at the next station grip the tube, clamps 47 are released and withdrawn, and the shaft 45 rotated back to its initial position. Fig. 12 shows a clamp 47 having two jaws 59 with replaceable outer portions 60 recessed at 62 to accommodate a tube. The jaws are hinged together by rings 61 fitting over projections on the jaws, and their inner ends are connected by toggle links 58 to an operating plunger 56. The jaws are slidable between side-plates 55 on an end fitting 53 and their inner ends are shaped at 63 to co-operate with guides 54, so that outward movement of plunger 56 first advances the jaws to surround tube 37, and then closes the jaws, and inward movement of the plunger first releases the jaws, then withdraws them. After the last work station, tubes are accumulated in pockets of an endless conveyer (Fig. 19, not shown), a counter moving the conveyer on when a pocket is full, and fed to a bundle tying device. Electric and fluid pressure circuits are described for operating the apparatus in the correct sequence.

Abstract: 1444289 Finishing bores by rolling MOGILEV AVTOMOBIL ZAVOD IM SM KIORVA 17 Dec 1974 54479/74 Heading B3M A finishing tool for working the internal surface of a cylindrical, conical, or partspherical bore includes a body 4, Fig. 1, having an annular groove 2 for accommodating balls (or rollers) 3, the base of the groove being provided with tangential passages 8, Fig. 2, through which a pressure fluid, e.g. compressed air, is directed to urge the balls along the groove and rotate them about their axes. The passages 8 communicate with a central bore 7 in the body and a fluid inlet 9. The fluid also serves as a coolant for the balls. The balls may be free to move radially, or a lip may be provided on the outer edge of one of the groove walls. Two parallel rows of balls in adjacent grooves may be provided, and the balls may have different diameters. To prevent the balls from leaving the groove when the tool is axially removed from the bore, a cylindrical outer cage (Fig. 5, not shown) is located around the entry of the bore. To finish a part-spherical bore, Fig. 10, the groove is inclined to the tool axis, and the tool is held axially stationary during working. A conical bore may also be finished, Figure 12, by using a vertical tool having several parallel rows of balls of differing outer diameter. The tool is moved axially to a limited extent, with the balls moving radially to accommodate the changing bore diameter. The balls are retained in the grooves when the tool is removed from the bore by undercut walls 45. In the case of a cylindrical or conical bore, the bore generatrix need not neccessarily be straight, in the bore may have an undulating surface. The bore may also be elliptical. When rollers are used in place of balls, two parallel sets of tangential grooves 8 may be used.

Title: Alarm system
Inventor: BAROWITZ PETER JACK
IPC: G08B13/16
Filed: 1967-11-30
Abstract: 1,246,264. Intruder alarms. ELLIOTT BROS. (LONDON) Ltd. 29 Nov., 1968 [30 Nov. 1967], No. 54626/67. Heading G4N. [Also in Divisions H3-H5] An alarm system comprises a linear array of geophones 12, alternate geophones (or groups of geophones) being connected to respective circuits 13, 14, adjacent geophones in each circuit being in antiphase so as to minimize false alarms due to distant noise. The system preferably includes a pulse discriminating circuit responsive to the pattern of human footfalls but immune to long bursts of traffic noise, to single heavy bursts and to the footfalls of small animals. After amplification at 15 . . . 17 and possible pulse lengthening, signals above a predetermined amplitude trigger a detector 118 which sets a bi-stable 122 the output of which triggers a monostable 125 via a gate 123. Monostable 125 opens a gate 126 for a period T1. An output from bi-stable 122 also releases a clamp 121 on peak detector 120 so that threshold detector 119 is triggered when the input signal falls to a predetermined percentage of its peak value. This action resets bi-stable 122, which triggers a monostable 128 producing a standard length pulse. Rejection of pulses of excessive duration is achieved by monostable 125 closing gate 126 at the end of period T1. Rejection of pulses of low repetition rate.- Standard length pulses from 128 are fed to a leaky pulse integrator 131 which triggers a Schmitt circuit 132 after a number of pulses at a sufficiently high rate. Rejection of pulses of high repetition rate.- Monostable 130 drives OR gate 127 for a period necessary to set a rechargeable monostable 129 which closes gate 123 and opens gate 124 for a period T2. If bi-stable 122 is set again within a time T2, its output is rejected by gate 123. Gate 124 also drives OR gate 127 which holds 129 in the charged condition as long as 124 is held open by bi-stable 122 being in the set state. A further link 133 allows bi-stable 122 to be reset by 125 if detector 119 should fail to trigger. The loop 124, 127, 129 may be replaced by a differentiator inserted between 122 and 123. Modifications.-In Fig. 3 (not shown), stages 15 . . . 17 are followed by separate detectors feeding a common chain of a limiter, Schmitt trigger, monostable, pulse integrator and second Schmitt trigger feeding an alarm-operating relay.

Title: Family of a.c. enable channel circuits for use as failsafe logic gates or electronic relays
IPC: H03K17/60
Filed: 1969-11-10
Abstract: 1291469 Fail safe gating circuits WESTINGHOUSE ELECTRIC CORP 10 Nov 1969 [3 Dec 1968] 54840/69 Heading H3T [Also in Division G4] A fail-safe gating circuit comprises an amplifying element passing a pulse or alternating signal under the control of a periodic or like gating signal, the amplifier having an output circuit which blocks direct current and the power for the amplifying element being derived from a capacitor charged under the control of complementary transistors having their bases fed in parallel with the gating signal. Fig. 1 shows the channel selector for the twenty-fifth channel of a pulse multiplex system, for example for selecting the upper speed limit of a railway track block. The Specification describes how any component failure including the freezing of the counter in any condition, leads to a "safe" output. The selector comprises a 32-counter 20 and fail safe AND gates 30 for detecting the combination of "zeros" and "ones" corresponding to the count of 25, this count allowing the pulse input at 36 to pass to a tuned fail-safe detector 32. The gates comprise a transistor 45 to the base of which are applied pulses M via a D.C. restoring circuit 68, 74 and derived from a master oscillator and shaper (Fig. 3, not shown) or from a previous stage. The collector receives a negative supply derived from a capacitor and rectifier circuit 50, 51 charged by a switching circuit 46, 48 when the output Q from FF1 is a "one". Transistor 45 thus conducts during coincidence of the "one" and a pulse M, causing the output transformer 62 to ring for a half-cycle, the resonant frequency corresponding to the duration of the pulse in order to eliminate spurious pulses. The turns ratio is chosen to provide unity gain in the stage. If the Q input persists (e.g. due to freezing of the counter) the capacitor discharges and the gate closes. Modifications.-The gate output may be a tuned circuit with capacitive instead of inductive coupling to the output terminals. In Fig. 4 (not shown) the gate is rearranged to be opened by a "zero" input. The gate may also be controlled by a so called " comma-free code" having a predetermined minimum repetition frequency. Pulses below this frequency allow the collector supply to decay and thus fail to safe. Pulses M could be replaced by sine wave in which case the output would be turned to this wave and in Fig. 5 (not shown) the gate transistor 45 is replaced by a transformer coupled push-pull amplifier.

Abstract: 1326396 Checking recorded data FUJITSU Ltd 19 Nov 1970 [20 Nov 1969] 55142/70 Headings G4C and G5R In a magnetic tape system having spaced read and write heads a writing check system utilizes the read head as a write monitor and produces an error signal if data are read from the tape at times when they should not or are not read at times when they should. Signals read from separate tracks on the tape are passed via an OR gate 30 to a pair of AND gates 31 and 33. The AND gates are enabled by means of a system of flip-flops, OR gates and delay devices such that an error signal is passed through OR gate 34 if read-out is sensed at times when it should not or is not sensed at times when it should, Four time periods are discussed. In the first between the start of writing and the arrival of the first datum at the readh head no read-out is expected. In the second between the arrival at the read head of the first datum and the cessation of writing read-out is expected. In the third between the cessation of writing and the arrival at the read head of the last datum read-out is expected. In the fourth between the arrival of the last datum at the read head and the cessation of tape transport no read-out is expected. Any error signal generated is used to initiate rewriting of the data.
