IPC: D05B15/00
Abstract: 106,510. Goddard, J. W., Jerram, A. E., and British United Shoe Machinery Co. March 18, 1916. Boot - sole sewing- machines; stitch-forming devices; presserfeet; presser-bars.-Improvements are made in machines having a rotatable horn which carries a looper for coaction with a barbed needle which penetrates the work from the side opposite to that which is on the horn to form a lock-stitch. Examples of such machines are described in Specifications 15756/12, 13600/13, and 13940/13. The shuttle 66 is supported by curved plates 73 carried in a casing 68 which is reciprocated axially by a rod 69 driven by an eccentric on the upright shaft 4 of the machine. The shuttle is rotated twice during each stitch by a shaft 15 carrying a block 76, in which are two longitudinal grooves guiding sliding pawls 77. Pins on these pawls run in spiral grooves on the fixed cup 81 and reciprocate the pawls to drive the shuttle. The casing 68 is provided with a hinged cover 82 of the kind described in Specification 19618/05, and on this cover is pivoted a loop-deflector 83 of the kind described in Specification 13940/13. The loop-deflector is moved by the cam 85 on the needle-bar 86. The presser-bar 105 carries a pivoted presser-foot 104 which, when the presserbar is lowered, is positively pressed on the work by abutment of the pin 106; but when the presserbar is raised, a spring plunger 107 causes the presser-foot to rock, and presses it lightly on the work or into the channel. The feed-point bar 108 slides in the presser-bar and is rocked by the arm 122 of a bell-crank actuated by a cam-track. The feed-point enters the work vertically and leaves it in an inclined direction. The feed-point bar and the presser-bar are pivoted at their upper ends to a plate 111, which is urged downwardly by a spring-pressed pivoted bar 118. The plate 111 is also pivoted to a lever 113 on a cam-actuated bellcrank 114, by which it is rocked so as to raise the presser-bar and the feed-point bar alternately, the other bar serving as the fulcrum of the plate 111. The presser-foot and feed-point are raised clear of the work by the treadle-operated lever 127. The presser-bar is locked by a pivoted member 129 moved by a cam on the main shaft against the action of a spring-pressed plunger 132. The presser-bar and work-feeding mechanism claimed in Specification 106,454 is disclaimed herein. The needle-bar is driven by a mechanism of the kind described in Specification 24489/09. The take-up shown in Fig. 5 comprises two levers 63, 64 pivoted so that the thread-engaging part of each lever moves towards and from the corresponding part of the other lever: both levers are rocked by groove-cams 7, 8 cut in a drum 6 on the upright shaft 4. A thread-locking device comprises a lever 53 carrying a spring-pressed plunger 55, which co-operates with a fixed arm 57 to lock the thread. The lever 53 is controlled by a camgroove 9 in the drum 6.

Abstract: 678,757. Protective cut-out arrangements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 13, 1951. [May 3, 1950] No. 10954/50. Class 38 (v). An electric traction or haulage system of the kind having a trolley wire supplied with D.C. from one or more polyphase mercury-arc rectifiers, is protected against breakage of the trolley wire by a relay responsive to the flow of rectifier output current of a harmonic frequency in a circuit including the trolley wire, the relay being arranged to disconnect the wire on cessation of such flow. As applied to a trolley wire T, fed from both ends, Fig. 1, relays 1, 4 respectively responsive to harmonic frequencies of 300 and 600 cycles per second are connected between the ends of the wire and the track D, the latter being connected by leads D1 to the star points of the rectifiers A, B. Wave traps a, d respectively pass 600 and 300 cycle currents, so that the relays are normally energized over the wire T by the currents from the rectifier at the opposite end thereof. If the wire breaks, both relays are de-energized to disconnect the wire from both rectifiers. The wire may be fed from one end only, Fig. 2, in which case an additional trolley or pilot wire T2 is connected in series with the wire T1 and an acceptor circuit 10 passing the frequency to which the relay 9 is responsive. These two arrangements may be combined, Fig. 3 (not shown), for a double-track system fed from three rectifiers, the protective arrangement of Fig. 1 being duplicated. In this arrangement, the choke of the acceptor could form the winding of a relay, or a relay coil could be connected in parallel with the choke. Alternatively, the relay (e.g. a thermal relay) may be energized by a secondary winding on the choke.

Title: Ac/dc regulated power supply
IPC: G05F1/20
Filed: 1969-03-03
Abstract: 1,255,846. Automatic voltage control. WESTINGHOUSE ELECTRIC CORP. March 3, 1969 [March 13, 1968], No. 11130/69. Heading G3R. In order to reduce the power loss in an A. C.- D. C. voltage regulator of the type comprising an input transformer 24, rectifiers 42, 44 and a series regulating transistor 52 controlled by a differential amplifier transistor 60, components 46, 48, 51, 54, 92 are added so that, in operation over range of A. C. input voltage at terminals 12, 14, the transistor 52 acts as the series regulator over the lower portion of the range and the transistor 54 performs this function over the upper portion of the range. Over the lower portion the transistor 54 acts as a forwardbiassed diode, reverse biassing the rectifiers 46, 48. When the A. C, input voltage reaches a predetermined value, corresponding to the point when the rectified voltage at taps 36, 38 exceeds the output voltage at terminals 18, 20, the transistor 54 conducts in the conventional manner, transistor 52 becomes an emitter follower amplifier driving the transistor 54 and the load current is then supplied by the transformer taps 36, 38. In effect the circuit performs an automatic electronic tap change at this predetermined value of A. C. input voltage, the above described operations being reversed as the input voltage falls from the upper to the lower portion of the range. Characteristics of power loss against A. C. input voltage are discussed for the prior art and the described regulator, Fig. 2 (not shown). In particular, instead of providing a sharp drop in power loss by the use of large filter capacitors and a transformer 24 of good regulation, smaller capacitors and relatively poor regulation are used to extend the dynamic switching range of the transistors 52, 54 during each ripple half cycle, so that minimum power loss is obtained over a substantial range on each side of the nominal A. C. input voltage. The base-emitter circuit of transistor 54 may be bridged by a pair of seriesconnected diodes which conduct at a predetermined threshold voltage. Other modifications include the provision of further additional circuits to achieve a plurality of automatic tap changes and the use of an autotransformer in place of transformer 24. Application of the invention to half wave rectification is also envisaged.

Abstract: 1353492 Displacement encoding; direction of movement EASTMAN KODAK CO 26 April 1971 [24 April 1970 (2)] 11265/71 Heading G4H Apparatus for scanning an information bearing medium to enable first or second sets of counting marks to be counted as the medium is moved in a first or a second, opposite direction, comprises two sets of twin photo-cells PC 1 -PC 4  (Fig. 13A) arranged to sense the marks of the first and second sets respectively as the medium is moved therepast and to provide first and second manifestations respectively thereof, and means for providing count-up signals in response to the first manifestations as the medium is moved in the first direction and in response to the second manifestations as the medium is moved in the second direction. The medium preferably carries, e.g. 40,000 microfilm images arranged in two longitudinal, parallel rows each assigned a number, e.g. from 1-20,000 along a first row numbered from left to right and 20,001-40,000 along a second row numbered from right to left and is provided with a mark fixed adjacent thereto, which in combination with the carrier medium causes intermittent light to fall on the photo-cells. Considering a first row only, photo-cells PC 1 , PC 2  are arranged adjacent and slightly separated in the direction of the medium such that the sequence of changes in their conductive state is indicative of the direction of movement of the medium. Switch 104, Fig. 13B, is placed in a " 1 " position to cause a signal at gate 111 to enable NAND gates 50, 52, 88, 89, 92, 93 and as the state of the cells is changed, series " 0 " and " 1 " signals appear at gates 56, 57 and are applied at J to flip-flops 68, 70 together with their inversions at K. These signals are also fed to a system of gates 63-82 to provide clock pulses of, e.g. 5 Ásec. duration at 82 which are applied to the terminals CP of flip-flops 68, 70 such that at the trailing edge of a clock pulse and until the next signal change occurs, the outputs Q, Q equal the input, but at all other times, the signals Q, Q are those present at J, K at an immediately preceding time interval. The signals at J, K, Q, Q of both flip-flops are taken to NAND gates 88-91 and 92-95 as shown causing one of the two enabled gates 88, 89 or 92, 93 to conduct and a " 1 " signal to appear at gate 98 or gate 100 to the J, K input of a third flip-flop 114 of similar type connected to receive the same clock pulses at CP. Gates 116, 117 are also enabled by the clock pulses and provide an output when a "count-up" signal is present at a certain time and at an immediately previous time (i.e. both J, Q signals are " 1 ") or a " count-down " signal when a similar condition is met respectively. If the medium is dark with light marks, switch 102, Fig. 13B is placed in the " 2 " position, otherwise in the " 1 " position. The situation is similar for the second set and switch 104 is placed in position " 2 ". This apparatus may be used with the system disclosed in Specification 1,353,491.
