Abstract: 444,583. Circular-loom stop-motions. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and JABOULEY, J., and YEADON, R., c/o British Celanese, Ltd., Spondon, near Derby. Sept. 21, 1934, No. 27168. [Classes 142 (i) and 142 (ii)] A detector 12 pivoted at 13 is caused by a spring 18 to press against the warp threads in turn and, in case a gap in the warp occurs owing to faulty shedding, &c., to engage a contact 20 and close a circuit operating mechanism whereby relative motion between the shuttles and warp is brought to an end to stop weaving. In a loom with stationary shuttles, this is effected by connecting the normally stationary ring carrying the shuttles to a rotating part. In a loom with rotating shuttles, the shuttle carrying ring is stopped. A feeler 12 may be provided for each shuttle acting in the vicinity of a gap therein. The contacts 20 may be connected by leads 24 and the springs 18 by leads 23 to slip rings 25, 26, carried by a ring 27 rotating with the shuttle. Switch members 21 controlled by sliding rods 22 of stop mechanism of the type described in Specification 424,789 are connected to the slip rings 25, 26, which are in circuit with a solenoid 30. When this is energized, either by means of the feelers 12, or by the members 21, which are controlled by warp jamming &c., or weft breakage &c. a spring-controlled lever 33 is released, and a brake band 35 is applied to and stops the rotation of the ring 27. The loom drive may also be interrupted by means of a further solenoid included in the electric circuit and controlling clutch mechanism as described in Specifications 441,617 and 441,618. The Provisional Specification also refers to Specifications 396,758 and 413,376.

Abstract: 689,097. Cutting blocks from an extruded rod of ice-cream &c. ROSE BROS. (GAINSBOROUGH), Ltd. Oct. 19, 1950 [Oct. 25, 1949], No. 27373/49. Class 87 (ii). [Also in Group XXX] A rod 11 of ice-cream is extruded onto a conveyer 12, and the speed of the conveyer is kept the same as the speed of extrusion of the rod by a rotary member 16 which engages the rod and actuates a servo-mechanism 15, the output of which is connected to a shaft 24 driving the conveyer. The rod is cut into blocks 32 by a knife 31. The knife is reciprocated vertically by an eccentric 37 driven from the shaft 24, and is moved horizontally at the same speed as the rod, during cutting, by an eccentric 43 driven from the shaft 24. The knife is thus driven synchronously with the conveyer, so that equal lengths are cut from the rod. The blocks 32 fall onto a delivery conveyer 46, having spaced pushing elements 47, which is driven from the shaft 24 at such a speed that it moves through a distance equal to the spacing of the elements 47, during a cutting cycle. The knife may also be of the rotary type or in the form of a wire. The delivery conveyer may comprise a series of spaced pockets each adapted to receive a block. The rod or the cut blocks may be passed through a freezing chamber 28. According to the Provisional Specification the cut blocks may be transferred to a pocket of the delivery conveyer by a member which lifts the block clear of its suporting surface. Specification 656,221 is referred to.

Abstract: 690,760. Multiplex pulse signalling. PYE, Ltd. Nov. 21, 1951 (Nov. 21, 1950], No. 28394/50. Class 40 (v). The sound channel in a television system is provided by a group of pulses occurring during each interline blanking period and produced by delaying by appropriate intervals modulated pulses derived from signal samples taken during a preceding line interval at times separated by more than the interline blanking periods. In the embodiment described, pulses, of a frequency three times the line recurrence frequency, are generated in circuit 10, Fig. 5, modulated in duration by the audio signal in circuit 11 and passed to the distributer 12. The latter is controlled by the output of a 3-to-1 divider 20, fed from the generator 10, so that the modulated pulses are directed sequentially into three channels I, II, III. Delay networks 13, 14, in channels I, II, respectively, cause each sequence of three pulses to be grouped to occupy an interval less than the interline blanking period, after mixing in circuit 15. The mixing circuit 16 receives the pulse groups from circuit 19 and the television waveform from generator 18, its output feeding the transmitter 17. At the receiver, the signal output from circuit 31, Fig. 6, is applied to the vision tube 24, the sync. separator 22 and the sound pulse gating circuit 25. The latter is controlled by a blanking pulse generator 26 fed from circuit 22 and selects the pulse groups, the individual pulses of which are sequentially directed to channels I, II, III by circuit 27 which is controlled by pulses from circuit 28 derived from circuit 26. Delay networks 29, 30 in channels II, III, respectively, re-arrange the pulses in the mixer 31 with uniform time intervals therebetween. The mixer output is applied to the pulse demodulator 32 feeding the loud-speaker 33. Specifications 564,511 and 621,479 are referred to.

Abstract: 870,076. Speedometers. SALZGITTER MASCHINEN A.G. Sept. 10, 1957 [Sept. 12, 1956], No. 28470/57. Class 106 (3). [Also in Group XXI] An apparatus for measuring and indicating the speed of locally-arranged hydraulic driving- motors for deep bores comprises an hydraulic impulse generator connected with the driving motor so that impulses from the generator have a frequency depending upon the speed of the driving-motor, and a remotely disposed indicating instrument responsive to the frequency of the impulses. The hydraulic boring turbine has a rotor a and a stator b each provided with discs e, f, preventing axial and radial movement of the rotor, and with turbine stages u and v. At one end of the rotor a a disc h is fixed which has a number of holes k corresponding with holes i in a disc g fixed to the stator b. When the holes are in register the turbine driving fluid flows to stages u, v through passages c, d. The fluid is thus given a series of impulses which are reflected back from the bottom of the bore-hole and depend upon the speed of rotation of the rotor a. The impulses act upon a diaphragm in the fluid supply line which may be made to operate an acoustic instrument, a reed type frequency meter or other indicating instrument electrically or otherwise. The indicating instrument may be connected to electrical limit switch gear in known manner to raise or lower the boring-rods to which the turbine is attached and thus readjust the speed should it fall below or exceed predetermined limits. The discs h and g may themselves act as a sound producer and the portions between the holes may consist solely of vanes so that the discs form an additional turbine stage.

Title: Improved photo-electric apparatus for light analysis
IPC: G01J3/51
Filed: 1937-10-19
Abstract: 499,230. Photo-electric apparatus for light analysis. MULLARD RADIO VALVE CO., Ltd., and EAGLESFIELD, C. C. Oct. 19, 1937, No. 28508. [Class 40 (iii)] [Also in Group XX] Photo-electric apparatus for the analysis of light comprises a cathode ray-tube and light sensitive means for controlling the deflection of the ray in one direction in accordance with the intensity of the spectral component of the light under examination at that instant. In one embodiment, the light 10, Fig. 1, is directed through rotating analyzing filters 12, which are arranged in order of wavelength, to the photo-electric cell 11 the output of which is applied to the Y-plates 20 of a cathoderay tube 21 to cause a deflection proportional to the intensity of the spectral component being examined. The output of a time base circuit 23, which is synchronized by means of contacts 24, 26 with the rotation of the filters 12, is applied to the X-plates 22 to cause a deflection which is proportional to the wavelength of the above spectral component. This causes a complete response curve to appear on the screen of the tube. Each filter passes a narrow band of wavelengths, the pass range of adjacent filters overlapping and the spectral range to be analyzed is presented to the cell in successive finite steps of wavelength. To compensate for varying spectral response of the cell and filters, the contact device 29, 30 shunts the input of the amplifier 19 with resistances 32. A rocking prism and a fixed slit plate may replace the rotary wave filter. A second embodiment, Fig. 2, comprises a prism 34 transmitting the light to be analyzed to the mosaic 35 of an iconoscope 36, the output of which is applied to the deflecting coil 38 of a tube 39. The output of a time base circuit 40 is applied to coil 42 of the tube and coil 41 of the iconoscope. A device 43 provides a high frequency "sweep" at right-angles to the time base by means of. coil 44. To correct for varying spectral response of the iconoscope, an adjustable aperture may be arranged between the prism and the iconoscope or, alternatively, a control 45 may vary the amplitude of the additional sweep at different parts of the spectrum. The response curve may be photographed. The invention may be used to determine quickly the sensitivity of film, the colour of television screens, the emission of lamps, or the colour of dyed or painted goods.
