Patent GB-126598-A (GB)
Title: Sewing Machines.
Inventor: FAIRWEATHER WALLACE
IPC: D05B29/06
Filed: 1918-07-02
Abstract: 126,598. Fairweather, W., (Singer Manufacturing Co.). July 2, 1918. Eyelet-hole sewing-machines; starting and stopping gear; needles, vibrating laterally.-Relates to sewing-machines for forming a series of zigzag stitches succeeded by a line of straightaway tying stitches such as required in stitching the eyelet holes common to Madeira embroidery. The needle-bar frame 30 is oscillated about its pivot 31 by a link 23 actuated through an eccentric-rod 20 by a shaft 18 which is driven from the main shaft 4 through a two-to-one reducing gear. A movable pivot is provided for the link 23 by a stud 73 pivotally connected to an arm 72 of a short shaft 71. The stud 73 is carried by one end of a link 74 provided with a hub 75 journaled in the end of the link 23. The shaft 71 is adjusted to determine the amplitude of needle vibration from a manually controlled rook-shaft 43 through a link 69 and crank-arm 70. The shaft 43 carries an arm 77 with an index linger 81 travelling over a scale on the face-plate. Stops 79 and 80 are provided corresponding respectively with the adjustment for producing the tying and zigzag stitches. The connexion between the link 23 and the needle-bar frame 30 consists of a stud 28 carried by the latter and journaled eccentrically in a cylindrical block 25 carried by the link. Adjustment of the block 25 determines the field of vibration of the needle, the block being retained in any position frictionally bv a spring-pressed plunger 41 and being provided with a scale traversed by an index finger 36 on the link. The shaft 43 is in two parts resiliently connected by a spring 78, the part carrying the adjusting devices being in the form of a sleeve 48 surrounding the main part 43 which is actuated against the action of a spring 85 by a crank 53 and treadle rod. During the formation of the zigzag stitches, the stopmechanism 62 of the machine is held inoperative by a latch lever 103 carrying a trip arm 102, and a cam 94 on the shaft 43 acts on the arm 87 of a spring-controlled shaft 86 which carries another arm 88 provided with a lead-nut 90 adapted when the shaft 43 is released at the completion of the zigzag stitching to engage a threaded sleeve 96 keyed on the main shaft 4. During the formation of the tying stitches, the sleeve is moved axially until a flange 108 thereon trips the latch 103 and allows the stop-mechanism to operate. The machine is started by rocking the shaft 43 which through a lost-motion device throws out the stopping gear, and a cam frees the sleeve 96 which is returned to its initial position against a collar 100 by the spring 98.

Abstract: 1367094 Discharge lamps; discharge treatmerit C F WEISSFLOCH M R WERTHEIMER and R G BOSISIO 7 Feb 1972 [13 Feb 1971] 4611/71 Headings H1D and H1X [Also in Division H5] Microwave energy is transmitted to a gas 7 using a slow wave structure 6 between the energy source 1 and the gas 7, the gas being at a controllable pressure and flow rate. The gas 7 flows through a container 8 in close proximity to the slow wave structure 6, which is a broad band, travelling wave structure, preferably of the strapped bar type, Figs. 4-6 (not shown). A vacuum pump 13 and flow regulator 15 control the gas flow. The unabsorbed energy is absorbed in a load 11. Container 8 is of quartz or other microwave-transparent material, and is cooled by a fan 18, or a cooling liquid. A double-walled radiation shield 9 is transparent and waterfilled. Container 8 is inclined at 3 to 10 degrees to the slow wave structure 6. Two structures 6, 61, may be used, Figs. 15, 22, 23, 26 (not shown). Slow wave structures of the comb-type, laddertype, zig-zag type and helical type may be used, Figs. 16-19 (not shown). Material in the form of a web, film, foil or plate is treated by the gas discharge, Figs. 22-25 (not shown), e.g. to improve the bonding and printing characteristics of fibres or a polyethylene film surface or to improve the dyeability and washability of polyester textile materials, or to reduce shrinkage of wool. Material in bulk form, e.g. granular or fibrous materials, may be treated by the discharge, Fig. 26 (not shown). Organic vapour may be treated to form a solid polymer film, e.g. for encapsulating electronic components. A CO 2  laser "pumping" embodiment is described, Fig. 27 (not shown). The gas discharge may be used as a light source, or a source of infra-red or ultra-violet radiation. Alternatively the discharge may effect chemical reactions of gaseous organic or inorganic compounds, e.g. cracking hydrocarbons. Reference is made to forming protective oxide or nitride layers on metals or semi-conductors, to chemical synthesis of hydrazine and acetylene, and to "crosslinking" applications. Gases used include nitrogen, oxygen, air, argon, helium, carbon monoxide, carbon dioxide, xenon and mixtures. Another possible use of the invention is in spectral analysis.

Filed: 1965-02-03
Abstract: 1,094,042. Substation apparatus. ERICSSON TELEPHONES Ltd. April 29, 1966 [Feb. 3, 1965], No. 4676/65. Heading H4K. In a repertory dialler, each number is stored on a matrix of square-loop cores. As shown, the cores corresponding to the number 4289 are threaded by a wire wb whereby when key Pwb is actuated a current flows which is sufficient to switch the state of these cores. In addition, contact PW is closed, whereby a columnstepping register D is set to its D1 stage and a relay E is operated. The latter via its contact E4 triggers a pulse generator PG which emits one pulse. The latter passes via operated contact E2 and one of the wires of the first column to stage D1 whereby a read-out pulse occurs on row 4 as the core reverts to its original state. Reception of the read-out pulse in stage 4 of stepping register C causes bistable A to set to its 1 state whereby multivibrator M is started. The C register is counted down, whereby four pulses are repeated via gate G to line. When stage C1 of the counter is reset, stage CO is set whereby the counter counts down through all its stages, but as G is now inhibited pulses are not repeated therethrough and an interdigital pause is obtained. When stage C1 is next reached bistable B is reset so as to trigger PG and thus start read-out of the second column, the trailing edge of the first pulse from PG having stepped D on to its second stage D2. The process repeats until all the digits have been read out whereafter E restores due to the lack of holding potential from bistable A. A number may be temporarily stored by operating key PD together with the relevant ones (taken in succession) of keys Pd0 to Pd1 In this case E is inoperative and half-write pulses occur on the other column and row wires so causing a particular core to switch its state. When the number has been set up it is destructively read-out by actuating key SB with similar results to the actuation of PW.

Title: Train location control system
IPC: B61L3/22
Filed: 1966-02-03
Abstract: 1,140,085. Automatic train control. TELECOMMUNICATIONS RADIOELECTRIQUES ET TELEPHONIQUES T.R.T. 3 Feb., 1966 [5 Feb., 1965], No. 4835/66. Heading B7N. In an automatic train control arrangement, location and speed information is transmitted from the train to a control station which compares the train performance with its programmed performance and transmits control information to the train to reduce any difference. A line-side wire 1 extends along the track and is divided into sections by high pass filters 2B-D which confine different frequency location tones from generators 6BC-6DE to their respective sections. A train in section CD receives the location tone (below 5kc/s) from generator 6CD via pick up loop 5 and applies it via low pass filters 7 and 8 to a ring modulator 9 supplied also with the train characteristic frequency signal (above 50kc/s) from source 11. The lower side band of the modulated output is selected in filter 12 and is further modulated in unit 13 by train speed information supplied by tachometer 14. The resulting signal is passed via high pass filter 15, the loop 5 and the line 1 to the control station A. Signals at the train characteristic frequency are selected by a filter 16 in one of a number of units each associated with a particular train and applied to a demodulator 18 which is also energized by a signal from source 17 at the train oscillator frequency. The resulting location tone signal is applied to a display unit 20. In addition the input signal is also applied to a second demodulator 19 which derives a speed signal which is displayed in unit 21 from which an indication of the distance travelled in the section can be obtained and displayed in unit 22. These information signals are also applied to a discriminator C which compares the train actual performance with that of a programmed performance and the difference signal modulates in unit EE a signal between 10 and 20 kc/s characteristic of the train which is transmitted via the line 1 to the train. The signal is passed via filter 7, 23 to a demodulator 24 which supplies the difference signal to unit 25 to control the speed of the train.

Title: Improvements in electrical communication systems
IPC: H04J7/00
Filed: 1942-04-23
Abstract: 554,456. Multiplex signalling; directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). April 23, 1942, No. 5449. [Class 40 (v)] In a multiplex communication system, a pulsemodulated carrier wave is transmitted over radio links, wave guides, or wires, and the channels are identified by a different characteristic of the pulses, e.g. by different pulse amplitudes or by different pulse duration. Fig. 3 shows three series of pulses a, b, c, the channels being identified by pulse amplitude, and separation effected at the receiver by cutting off the pulses at the respective levels 9, 10, 11. A receiver for two such channels, Fig. 4, has the aerial 12 connected through an amplifier 13 to two valves 14, 15 biased respectively to the levels 9, 10 of Fig. 3. The received waves pass through further amplifiers to detectors 18, 19 whence the pulses pass through amplifier 20, 21 to pulse demodulators 22, 23 and to telephones 24, 25. The a channel pulses are excluded from the b channel by a connection 26 or 27 which blocks the b channel while an a pulse is present. If this blocking connection is made at a radio-frequency stage, a phasing device is included. The pulse demodulator 23 of the b channel may also be rendered inoperative by the a pulse. Different carrier frequencies may be used for the various channels in order to avoid difficulties due to continued phase opposition of the carriers conveying wanted and unwanted signals. When the channels are distinguished by different pulse duration, separation of the pulses at the receiving end is effected by a filter having a suitable pass-band width, the emerging pulses being distinguished by their amplitude, and being separable by biased amplifiers. If transmissions are to be received from different directions, the receiver may make use of a vertical aerial 36, Fig. 6, and a frame aerial 35. The received waves are passed through frequency-doublers 41, 42 to limiters 39, 40 which reduce both received waves to the same level so that in general a balance can be effected in the circuit feeding the pulse demodulator 44. For positions, however, of the frame aerial at or near that of zero reception, the balance is upset and the signals received. A second directive aerial may replace the vertical aerial.

Abstract: 1495453 Charge-coupled devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Feb 1975 [13 Feb 1974] 5490/75 Heading H1K In a CCD in which majority charge carrier packets are transferred along a semi-conductor layer 3 (Fig. 2) on an opposite conductivity type substrate 4 by the action of clocked voltages on capacitively coupled electrodes 13, a highly doped buried layer 14 of the same conductivity type as the layer 3 is provided between the layer 3 and the substrate 4. Optionally a further highly doped layer 20 (see Fig. 6) of the same conductivity type is provided at the surface of the layer 3. The layers 14, 3 and 20 are preferably epitaxial, but in a modification (Fig. 6) in which there is provided a plurality of discrete highly doped zones 14a, 14b &c. these are formed by diffusion or implantation into the substrate prior to deposition of the layer 3. In Fig. 6 the zones 14a, 14b &c. underlie alternate electrodes 13b, 13d &c. and provide directionality for two-phase operation using the electrode interconnection sequence shown. In a variation each electrode overlies a discrete highly doped zone located asymmetrically relative to the electrode to obtain the necessary directionality, the two phases being connected to alternate electrodes. In either continuous layer or discrete zone embodiments there may be a lightly-doped layer of either conductivity type between the highly doped layer 14 (or zones 14a, 14b &c.) and the substrate 4. Fig. 2 also shows a highly doped region 7 of the same type as the substrate 4 extending down to the latter to laterally isolate the CCD region. The region 7 may stop short of the substrate 4, lateral isolation being completed beneath it by the merging of depletion regions. Although the electrodes 13 are shown as conductive layers capacitively coupled to the semi-conductor through oxide layer 6 they alternatively take the form of Sohottky barriers, PN junctions or a piezoelectric layer. Input of majority charges to the device may either be by means of highly doped input region 10 (Fig. 2) or by the absorption of radiation.
