Patent GB-1289990-A (GB)
IPC: D05B51/00
Filed: 1969-12-08
Abstract: 1289990 Sewing machine FARAH MFG CO Inc 8 Dec 1969 [30 Jan 1969] 59871/69 Heading D1G In a sewing machine an upper thread break detector comprises a switch controlled by the unbroken thread to repetitively open and close the switch, ducting means responsive to the repetitive operation to energise a relay, and means, operable when the thread breaks, the switch remains closed and the relay is deenergised, to signal that a break has occurred and/or stop the sewing machine, the switch being connected with a voltage source in a high impedance circuit so that fouling of the switch contacts by contaminents, which raise the contact resistance, can be tolerated. The switch is formed by a fixed contact 9 and the check spring 8 which is pulled away from contact 9 at each stitching cycle by the action of the take up lever. Operation. Relay 16 is energised when the sewing machine motor clutch is engaged to start the machine, the relay energising the circuit of lamp 17. The upper thread engages a loop 10 on the check spring 8 to open the switch contacts during stitch forming, the transistor 13 then being ON to charge capacitor 18 and switch transistor 14 ON and energise relay 15 to open the circuit of lamp 17. During the on-off action of the switch during normal stitching capacitor 18 maintains transistor 14 in this ON condition. On breakage of the upper thread the switch remains closed, capacitor 18 discharges and transistor 14 is turned OFF to de-energise relay 15 and complete the warning lamp circuit. The specification describes the values of the components of the circuit and states that a switch contact resistance of several thousands ohms, due to contaminants such as lint, may be tolerated. U solenoid valve may replace the lamp and then controls a pneumatic cylinder operating a brake and clutch.

Each input phase ABC is connected via a transient suppressing, reconstitution circuit 1, 11, 18 comprising a current transformer 123 having components 126 ... 129 to improve its frequency response and arranged to subtract from its output, transients due to the conduction of thyristors 4. Each variableduration monostable circuit 103 ... 108 is arranged to provide a pulse commencing at the zero crossing of the input voltage (as detected by a threshold circuit 130 ... 132 and having a duration dependent on the instantaneous value of a symmetrical triangular wave produced by integrating at 100 a reference squarewave D<SP>1</SP>. A constant duration trigger pulse is generated by monostable circuits 139 ... 144 at the end of each pulse from 103 ... 108 and after, amplification at 145 ... 150, triggers the appropriate thyristor 4. Passages through zero of the output current in each phase are detected by a saturable reactor 26 (see Specification 1,195,581) which provides high frequency pulses whenever the output current is less than 10 mA. These pulses are fed to a series of gates, bi-stable and monostable circuits 109 ... 121 so as to inhibit the triggering pulses in such a way that no two series-connected thyristors conduct simultaneously.

An aerial 13 carried on the vehicle is energized by the vehicle battery 15 and an oscillator 16 and normally a current sensor 17 produces no output. As the aerial passes over energy absorbing devices 12 in the lane 11 the input current to sensor 17 changes and a pulse is produced.

Abstract: 1346983 Passenger conveyers; endless conveyers R SALVADORINI 8 Sept 1971 [16 April 1971] 28088/73 Divided out of 1344141 Heading B8A A conveyer belt formed of a series of interlinked slots, has high speed sections X (Fig. 2) where the slats are in overlapped relation, and low speed sections Y where the slats are in lateral non-overlapping alignment, and where passengers may get on and off. The return sections of the belt pass underground at A. The slots may be carried by an articulated series of parallelogram linkages (as shown in elevation in Fig. 2). The belt is formed by links 6 which are themselves formed by a series of interlinked elements. The latter comprises a laterally spaced series of plates 9 (Fig. 8) which interdigitate with the plates 12 of each adjacent link 20, and form a tread surface for the passengers. The coupling of the elements 9 is so designed that the connected elements are rigid against the downward load of the passengers, but are able to curve in the other direction around guide pulleys 11. Each link 9 is pivoted at one end to the upper open apex of a respective parallel linkage, its other end being connected via resilient means 7 to the lower apex of the next adjacent linkage. At the upper apex of the latter linkage, the link passes around a toothed wheel 11. The conveyer may be driven by separate motors connected to driving wheels at positions along the conveyer. These motors may be connected in pairs in parallel, the pairs being connected to each other in series. The conveyer of the invention may be used as a service conveyer to take passengers from a stationary position to a constant speed conveyer. Hand rails (14), (21) (Fig. 10, not shown), may be mounted on the linkage.

Abstract: 1348134 Transistor frequency detectors and oscillators GIRLING Ltd 23 July 1971 [9 Sept 1970] 43114/70 Headings H3A and H3T [Also in Division F2] A frequency detecting system comprises: transistors 12, 12a switched by A.C. signals developed in respective windings 11, 11a; frequency detectors 21, 21a responsive to the frequencies of the respective A.C. signals; switching means 22 for connecting one or other of the detector outputs to a load 23; and capacitors 32, 32a cross-coupling the two transistors 12, 12a via switches 33, 33a such that, when the switches are closed, the two transistors constitute a multivibrator which operates at a frequency determined by the capacitors 32, 32a and windings 11, 11a. The arrangement is employed in an antiskid system, in which the signals induced in windings 11, 11a have frequencies representative of the angular velocities of wheels on the opposite ends of an axle. The output of whichever detector 21 or 22 detects the lower frequency is passed by the switching circuit 22 to a differentiator 23 to produce a signal dependent on deceleration, and when this signal exceeds a value determined by resistor 26, the brake actuating solenoid 24a is operated. In order to test the system, switches 33, 33a are closed and the multivibrator thus formed oscillates at a rate corresponding to a constant wheel speed. When the switches are reopened the output from differentiator 23 is equivalent to that of an infinite deceleration and operates solenoid 24a. The switches may be operated automatically when the ignition is turned on.

Mould portion 27 has flanges 28 engaging side walls 29 of portion 26, walls 29 being prised apart for opening or closing the mould by wheel 36 in cooperation with pressure roller 38. Oven 42 slopes downwardly to facilitate gas escape from the foaming moulding, which may be polyurethane, preliminarily curing or gelling the moulding so that it can bend through a helical path in oven 43 without detriment. Trough mould portion 27 is guided over arc 46, urged outwardly by weight 47. Mould portion 26 is guided over similarly tensioned arc 49. The foamable mixture is provided from tanks 52-55 to mixing head 60 and metered to trough mould portion 27 at station 40. A strengthening cord, wire or wire mesh from winding 62 may also be incorporated at the filling station. The mould is then closed and passed down through oven 42 by guide wheel 77, driven chains 78 and driven rollers 79 and associated pressure rollers 80, the mould being self-supporting therebetween. At oven 43, the foaming material having completed its expansion, the mould is bent into a helical path of constant radius and driven therethrough by chains 84 and rollers 85. A central forced air heating system 82 circulates heated air to ovens 42, 44 as well as oven 43. After passing through oven 44, mould portions 26, 27 are forced apart by rollers 95, 96. Cured product 100 is stripped from portion 27, squeezed between rolls 108, 109, and trimmed by wheels 114, 113. Mould portions 26, 27 are cleaned by air jets 101, 102 and cleaning fluid jets 103, 104 which may also apply release agent. The product may be used as sealing strip for windows, doors, and in automobile bodies, and for windlaces, gaskets, seals, beading &c.
