Title: Improvements in multiple feed circular knitting machines
IPC: D04B9/54
Filed: 1957-05-16
Abstract: 829,806. Knitting. SCOTT & WILLIAMS Inc. May 16, 1957 [June 12, 1956], No. 15560/57. Class 74 (2). A guard member 79 is attached to the dial of a two or more feeder circular machine having welt transfer bits slidably mounted in the dial. A downwardly projecting guard portion 80 extends below the level of the bottom of the bits and encloses them in their retracted position for the majority of the circumference of the dial. A gap is left extending over one feeder and through which the transfer bits project to receive and retransfer the welt loops. By the provision of the guard portion 80 on the member 79, the transfer bits can be advanced to receive the alternate needle loops of the first course fed at the first feeder. As the welt bits are withdrawn prior to feeding the second course at the second feeder the guard portion 80 encloses the bits holding their loops and serves to hold these loops down to prevent them slipping off the bits as the needles rise to receive the next course and subsequent courses. On completion of the second course the sinker webs can also now engage their loops to hold the fabric down prior to knitting the next and subsequent courses. Specifications 102,711, 488,241 and 704,843 are referred to.

Title: Improvements in or relating to circuit arrangements for generating signals suitable for automatic frequency control
IPC: H03C3/09
Filed: 1943-09-29
Abstract: 568,825. Automatic frequency control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 29, 1943, No. 15977. Convention date, Sept. 29, 1942. [Class 38 (iv)] Frequency drift in an oscillator is corrected by combining the drifting oscillations with stabilized oscillations of the same frequency and of greater amplitude, and passing the combined oscillations to an amplitude-modulation detector and to a frequency-modulation detector. When deviation occurs, each detector produces a beat frequency, and the two beat currents are combined in opposed rectifiers to produce a D.C. voltage which is used to correct the original frequency drift. As shown, oscillations from the main oscillator 12 are first heterodyned to a lower frequency by mixing with a fixed frequency from a source 10 in a mixer 20. This lower frequency is combined in the circuit 30 with oscillations of greater amplitude and of the same mean frequency from a fixed-frequency source 22. The combined wave is applied to the grid circuit of a valve 38, which operates by grid rectification to detect changes in amplitude, and which feeds the resultant beats through the coupling 80, 84 to the valve 90. The valve 38 also operates as an amplitude limiter removing amplitude modulation from its output which is fed to a frequency discriminator 40 of the kind described in Specification 489,094. The beats, which are present as a frequency modulation on the combined wave applied to the discriminator, appear across the resistances 48, 50 and are amplified in the valve 66, the output of which is applied in like phase to the cathode and anode respectively of diode rectifiers 74, 78. The output of the valve 90 is applied in phase opposition to the other electrodes of the diodes 74, 78, and a load resistance 100 is connected between the mid-point of secondary coil 92 and the earthed end of the secondary 70, the arrangement being such that the beat currents oppose each other in one rectifier and aid in the other. The D.C. voltage across the load 100 is smoothed by the network RC and is applied to the generator 12 to correct its frequency, e.g. in the manner described in Specification 504,766.

Abstract: 1,029,873. Electric selective signalling. L. J. CHU. April 17, 1964 [July 15, 1963], No. 16062/64. Heading G4H. In apparatus for producing a series of impulses representing signals derived from a moving body having signal areas thereon of substantially equal width, the signals are applied successively to a plurality of signal receivers, combined together and differentiated to produce sampling pulses which are used to sample a cumulative signal corresponding to the plurality of successive signals. In Fig. 1 (not shown), the optical image of a coded identification plate 2 on a vehicle scans along a row of signal receivers R1 to R7 as the vehicle moves, the receivers being the ends of bundles of light guides B1 to B7, the distances between adjacent receivers R1 to R6 each being slightly greater than the width of the image of one bit area of plate 2, and bundle B7 being thicker than the others. The bundles B1 to B6 lead to a single photo-cell D1, the output of which is differentiated at 4. The bundle B7 leads to a photo-cell D2, the output of which is sampled at 6 by the negative voltage spikes of the output of differentiator 4 to give a binary pulse train corresponding to the code group on plate 2.

Filed: 1926-06-26
Abstract: 279,530. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 26, 1926. Hydrocyanic acid; sodium cyanide. - Hydrocyanic acid is obtained by submitting vapour of formamide in the absence of other gases to the catalytic action of natural or artificial zeolites, calcium chloride or alkali carbonates. The production of carbon monoxide and ammonia is thus minimized. In an example sodium zeolite is employed at 400-450‹ C., and anhydrous sodium carbonate at 400‹ C. In the latter case some of the hydrocyanic acid reacts with the sodium carbonate forming sodium cyanide, so that the carbonate must be replaced by fresh quantities from time to time.

Abstract: 106.082. Harris. A. F. May 1, 1916, [Con vention date]. Stopping, tripping, and throw-out arrangements. -In a printing or like machine means are provided for simultaneously disconnecting the feed mechanism, and tripping the lowering mechanism of the delivery table upon failure of the feed supply. The pile table 114, Fig. 1, is supported by chains 115, 116 wound round drums 119 supported on shafts 121 at each side of the press. The shafts 121 are provided with worm-wheels 126 engaging, worms on a transverse shaft 123 operable by hand by a removable hand-lever at one end, or automatically by a ratchet wheel 139 secured to the shaft and engaged by a pawl 138 operated from a rotating shaft 87 of the delivery mechanism through gears 131, cam 132 and linkage 129, 134, 135, 136, 137. The extent of movement of the ratchet wheel 139 at each stroke of the pawl may be regulated by means of an adjustable guard plate 141 adapted to hold the pawl 138 out of engagement with the ratchet through a greater or less part of its stroke. The sheets are fed to the machine across a feed table 32, Fig. 3, by feed rollers 30 driven from the shaft 25 through a clutch 43 and gearing 40. The clutch 43 is connected to a rock shaft 69 which is also connected by link 48, shaft 150, and link 154 to a bell-crank lever 155 one arm of which is adjacent to a pin 146 on the pawl 138 so that when the clutch 43 is opened, the feed rollers 30 are disconnected, and simultaneously, the pawl 138 is moved out of engagement with the ratchet wheel 139 to stop the lowering of the table 114. The shaft 69 may be turned by a hand lever 74, and is also adapted to be turned automatically when a sheet is absent from the feed table 32. A trip-lever 63 is pivoted between a pair of notched disks fixed to a shaft 47 which is oscillated continuously by linkage 48, 49 from a crank disk on the shaft of the cylinder 20. One end of the trip lever is formed as a hook and the other and heavier end rests on the sheet.

Abstract: 530,051. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd., McWHIRTER, E. M. S., and WARD, H. J. June 2, 1939, No. 16281. [Class 40 (i)] A primary sub-station, Fig. 1, which is to receive signals from a number of secondary sub-stations, one shown in Fig. 2, distinguishes between the secondary stations by means of the time interval between a pair of signals the first signal given by the operation of a relay A closing a contact a<SP>1</SP> to start the movement of selector switches SS and PS which move synchronously under the control of synchronous motors SM, PM, clocks, pendulums, condenserdischarge circuits, or other means. As shown the motors are started by the operation of relays SMS, PMS. The sub-station shown has contact 5 of the selector switch earthed so that the corresponding relay D3 of the series D1- D9 is operated, closing a corresponding signal lamp circuit in the series DL1-DL9. If two secondary stations originate signals simultaneously both operate the corresponding signal lamps, but if one follows another it cannot operate to start its own motor SM because the rectifier MR inhibits current from the batteries of the relays D1-D9 which are of opposite polarity to the battery of relay PMS. If an earth fault occurs on the line L the relay PMS operates and starts the motor PM causing the relay E to close a signal lamp circuit EFL, the contact e<SP>2</SP> also isolating the lamp circuits DL1-DL9.
