Title: Shoe and method of making same
IPC: A43D21/12
Filed: 1961-12-28
Abstract: 963,721. Lasting; stiffeners. CAMPEX RESEARCH & TRADING CORPORATION. Dec. 28, 1961 [Jan. 5, 1961; Aug. 29, 1961], No. 46492/61. Heading A3B. A method of lasting the end of a shoe consists in using a stiffener which when lasted with the upper is flauid and mouldable but becomes rigid before the applied stress is removed. As described the stiffener-either a box toe or counter stiffener -consisting of a sheet of thermoplastic material is rigid at room temperature but becomes mouldable above a predetermined temperature and can be coated on one or both faces with a film of adhesive which is softened when heated above the predetermined temperature but is rigid and cohesive at a room temperature. The counter stiffener fits into the pocket between a lining 20 and the upper 21, and heat is then applied to soften the stiffener and adhesive and stress is then applied. The upper is mounted on a last L and stress is then applied using pincers N &c. The upper is moulded to shape by means of pads P &c. and auxiliary pads Z &c. The lasting margin of the upper, with part of the stiffener is then wiped across the insole S by wipers W &c. Cooling means may be provided in the wipers and/or the pressure pads to hasten the stiffening of the stiffener. Specification 963,725 is referred to.

Title: Apparatus for compensating for dead zone in servomechanisms
Inventor: TOIFL JAROSLAV
IPC: G05D3/20
Filed: 1965-11-03
Abstract: 1,080,180. Electric selective signalling. VYZKUMNY USTAV MATEMATICKYCH STROJU. Nov. 3, 1965, No. 46533/65. Heading G4H. A servomechanism arrangement comprises means for reducing the effect of static friction at the output shaft. Pulses which are to cause movement of the servo are added to clock pulses fed to a first counter for forward movement and subtracted from them for reverse movement. The final stage of the counter 10 feeds a switch 30 leading to one side of a bi-stable circuit 50. A second and equal size counter 20 is also fed by clock pulses, its half count stage feeding a second switch 40 connected to the other side of the bi-stable circuit. When a "forward " pulse passes to the first counter 10, the related switch connects the bi-stable circuit to an earlier stage of the counter. Feedback pulses from the servo return the first counter to synchronism with the second counter, whereupon the first switch reverts to its original state. An analogous operation takes place when a " reverse " pulse is received. In this way the output of the bi-stable circuit is given a relatively large phase displacement in response to the first " forward " or " reverse " pulse to overcome the friction.

Title: Electrical trip signalling system
IPC: H02H7/26
Filed: 1971-10-08
Abstract: 1369686 Protective arrangements QUINDAR ELECTRONICS Inc 8 Oct 1971 47057/71 Heading H2K An electrical trip signalling system for a supply network comprises for each power station a transmitter, Fig. 2, for generating two carrier signals of the same frequency but in phase quadrature with each other and each modulated by a corresponding one of two information signals, one of which changes to represent a trip, and a receiver, Fig. 3, for recovering information signals from modulated carrier signals received from a transmitter of another power station, each power station further including means for isolating that station from the network in accordance with the recovered signals. The one information signal may comprise a trip signal or a guard signal, and the other information signal is for noise monitoring purposes. The transmitter comprises a reference source 42 producing an in-phase carrier signal which is modulated at 44 by a trip or guard signal from a protective device 38, and a quadrature carrier signal which is modulated at 46 by a noise monitoring signal from a source 40. The modulated signals are summed at 48, filtered at 50 and transmitted with or without other signals to the receiver. The receiver includes an automatic gain control 64 to which is connected a modulator 68 which modulates the received signal with the in phase component of the recovered carrier signal supplied by a phase locked loop 66, the output from the modulator 68 being filtered at 76 and applied to a detector 78 which detects the trip or guard signal and provides an output signal at 80 via an inhibitor 82. A modulator 70 is connected to the gain control 64 through a 45 degree phase shifter 72 and modulates the received signal by the quadrature component of the recovered carrier signal supplied by the loop 66. The output from 70 is a constant D.C. signal, but when the level of this signal is less than or greater than preset limits due to "noise", a detector 86 triggers a squelch circuit 88 which causes a transistor 104 of the inhibitor to conduct so that the signal at 80 is a "guard" indication. The squelch circuit is also triggered by a level detector 90 should the output from the gain control be outside specified limits. The loop 66 is connected through a 90 degree phase shifter 74 or resistor 114 under the control of transistors 110, 112. one or other of which is rendered conductive by a control 94 in response to the output signal.

Title: Improvements in and relating to road traffic control
IPC: G08G1/01
Filed: 1964-11-20
Abstract: 1,027,880. Road traffic measurements. E. J. SCHEPERS. Nov. 20, 1964 [Nov. 21, 1963; April 16, 1964], No. 47399/64. Heading G4Q. In a system for indicating traffic stoppages in a road section having at least two mutually accessible lanes with the same traffic direction, for example, in a tunnel, the ratio of traffic volume in the left lane to traffic volume in the right line normally decreases from a high value at low total traffic volumes to unity at high total traffic volumes; if there is an obstruction in either lane the ratio will alter markedly from its normal value, and this alteration is detected and used to operate an alarm. Referring to Fig. 2 detectors 4 and 5 are placed in respective traffic lanes 2 and 3 and feed amplifiers 6 and 7. The outputs of the detectors at the beginning of the road section pass through OR gate 10 to a classifier circuit 11 which produces an output on one of the lines 12-15 according to the level of the total volume. The outputs of each pair of detectors pass to a comparator circuit 16 which compares the ratio of the traffic volumes with limits selected by the inputs on lines 12- 15 and produces an alarm output on line 17 if these limits are exceeded. At the lowest level of traffic volume when line 12 is energized, there is no upper limit to the ratio and the system responds to a difference in the number of vehicles entering and leaving a section between two pairs of detectors. When a gate 10 has not been actuated for a period, e.g. 10 seconds, equal to the maximum time assumed for a vehicle to pass between two pairs of detectors, a comparator 21 compares the counts in counters 19 and 20 and passes a signal to unit 22 if there is any difference in the counts. The signal from unit 22 inhibits the unit 22 of the succeeding section via lead 23 and is inhibited by an output from the succeeding comparator via lead 24. This prevents a false alarm caused by a false count which might be caused by a vehicle actuating a pair of detectors 4 and 5 simultaneously. An alarm signal passes through gate 25 if one comparator 21 but not the two adjacent comparators gives a difference signal and if line 12 is energized, i.e. there is minimum traffic flow. The detectors 4 and 5 may be of the capacitive type influenced by vehicle axles. The inputs to the counters may include coincidence detector circuits, Figs. 6 and 7 (not shown), so that a single coincident detection by both detectors of a pair generates an additional count unless followed within a short time by a second coincidence. In this way two vehicles passing over the detectors simultaneously are counted but a single vehicle passing over both detectors is only counted once as the signal due to its second axle cancels the additional count.

Abstract: 1,135,345. Standby power supply systems. STANDARD TELEPHONES & CABLES Ltd. 19 Oct., 1967, No. 47643/67. Heading H2H. A standby power supply system of the " nobreak " type comprises two constant current supply sources 2, 3, each having a Zener diode and a capacitor 9, 11 and 10, 12 respectively connected across the output terminals thereof, the sources supplying a load 1 by way of silicon controlled rectifiers 4, 5. Closure of a switch 13 energizes the source 2 whereupon the capacitor 11 charges to a voltage determined by the Zener diode 9-say 600 volts. To connect the source 2 to the load 1 a pulse from a pulse generator 6 is applied to the S.C.R. 4 which is rendered conductive. The current in the load 1 is such as to maintain a voltage of 570 thereacross and the Zener diode 9 becomes non-conductive. When it is desired to supply the load 1 from the alternative source 3 the switch 14 is first closed to energize the source 3 thereby charging the capacitor 12 to a voltage determined by Zener diode 10, again 600 volts. Thus the S.C.R. 5 is forwardly biased by 30 volts and when a pulse from pulse generator 7 is applied to S.C.R. 5 it will conduct and the capacitor 12 will discharge into the load 1, thereby back-biasing the S.C.R. 4 which will then become non-conductive. When the capacitor 12 is discharged the Zener diode 10 becomes non-conductive and, because the S.C.R. 4 is now non-conductive, the capacitor 11 re-charges and the system is ready for a change-over of supply sources when required. The pulse generators 6, 7 are actuated manually or automatically from a control unit 8 which may include suitable alarm devices for each source.
