Title: Method and apparatus for spinning yarns on open-end spinning machines and pneumatically removing fibre and trash waste  incident to spinning
IPC: D01H11/00
Filed: 1974-10-18
Abstract: 1457370 Removing trash from open-end spinning machines PARKS - CRAMER (GREAT BRITAIN) Ltd 18 Oct 1974 [5 July 1974] 45277/74 Headings D1D D1F and D1N  A method of spinning yarns in open-end spinning machines 10 comprises removing fiber waste from the rotors of a group of open-end machines through a first passageway A in each machine and removing trash waste from adjacent the paths of travel of fibers to the rotors through a second passageway B in each machine, the passageways A and B being connected to a source of airflow 70 common to all the machines in the group. The passageways' A contain primary filters 60 which have rotary filter screens 62 to temporarily trap waste before releasing it to a waste collection zone 80 with a rotary drum filter 81. A pressure sensor 66 activates rotation of the filter screens 62. A fire detector 100 in primary filter 60 allows a time delay in the event of fire to allow for the air stream to blow it out and then closes flap 116 to stop the air flow, stops the relevant spinning machine and releases extinguishant into filter 60. A similar detector 80a in the filter 80 shuts down all machines in the group and releases extinguishant into filter 80. The air flow from the trash waste collection is much lower than that of the rotor fiber waste to prevent good fiber being extracted by it. This is achieved by a restricting section 132 in passageway B. The trash waste first enters a collecting chamber before extraction through passageway B. This extraction may occur periodically e.g. by means of a belt 133 with apertures which pass the ends of pipes 31' from respective spinning stations (Fig. 7). Specification 1455066 is referred to.

[Also in Division E1] Concrete is cast in a bag-like mould compartmented by connections 5<SP>1</SP>, 14<SP>1</SP> (Fig. 8) between its opposed walls, and provided with spacers 9 which limit the extent to which the walls can bulge. In consequence the concrete forms several areas joined by portions which break if there is subsidence of the supporting ground. Dove-tail formations as shown, or formations of other shapes (e.g. Figs. 9 and 10, not shown) may hold the portions of concrete together. Dove-tails on the periphery of the mould may provide connections with similarly formed walls on an adjacent mould, or adjacent moulds may be joined by hooks and eyes. The mould may be filled through apertures 19, 20, 21 or through non-return flaps. Suspension wires may extend inside the hole and may be secured to some of the spacers 9 or prevented by nuts from pulling out. Portions of wire mesh within some of the compartments may engage spikes driven through the mould to hold it in position. The mould may be formed by fabric walls joined by cross-weaving and with cross-weaves forming the spacers 9. Alternatively, the opposite walls may be sealed, sewn or welded together.

After the switch closes, further movement of the stem and of lever 11 causes a portion 11B thereof to disengage from an adjustment lever 10 whereupon a leaf spring 10D rotates lever 10 clockwise about its pivot 16. Thereby the lever 10 is caused to engage and rotate a three limbed cam 14 fixed on the rotor shaft, so adjusting the angular position of the rotor. When the stem 13 is pushed inwardly it causes firstly disengagement of the lever 10 from the cam and then opens the switch to permit energization of the motor drive coil. The seconds hand may be set to a desired time by repeatedly moving the stem 13 inwards and outwards by the required number of seconds.

Title: Counter circuit
IPC: H04B1/16
Filed: 1970-12-18
Abstract: 1332516 Frequency dividers RCA CORPORATION 18 Dec 1970 [29 Dec 1969] 46007/72 Divided out of 1332515 Heading H3T In a frequency divider suitable for use in the stereo decoder disclosed in the Parent Specification, and for construction as an integrated circuit, a first bi-stable 201, 203 is controlled by a second bi-stable 209, 211 in accordance with pulses supplied to the base of a transistor 219, a chain of the dividers being connected together as required. With no input, both transistors 209, 211 are non-conducting and each time a trigger pulse is applied via transistor 219, the transistor which remained off during the previous pulse conducts and then returns to its off condition. Assuming that transistor 203 is conducting and 201 non-conducting, the biasing is such that when transistor 219 is turned on by a trigger pulse, a clamp transistor 231 maintaining the collector of 219 at a predetermined potential, transistor 211 is driven into saturation. The resulting fall in the collector potential of 211 is coupled to the junction of diodes 223, 225 so that 203 is cut off and 201 conducts. At the next trigger pulse transistor 209 will conduct causing bi-stable 201, 203 to change state again via the junction of diodes 227, 229. Outputs are taken via emitter-followers 233, 243 connected to the bases of transistors 203, 201 respectively. Further emitter-followers 239, 245 are connected to potential dividers in the emitter circuits of transistors 233, 243 respectively and provide logic output levels which via a transistor 253 in a further circuit of the type shown, block or pass the trigger pulses to the transistor 219 in accordance with the logic output. Additional transistors 257 may be connected in parallel with transistor 239 to provide more output signals.

[Also in Division C4] In a positioning device for a carrier bearing an orthogonal array of micro-images on a film, the carrier is slidable in the plane of the film by positioning means operative when a positioning key 72 is depressed to bring a selected micro-image to a projection position when the keys on keyboard 70 corresponding to the x and y co-ordinates of the selected image are depressed. The keyboard has, for the x and y co-ordinates, a bank of "tens" keys and a bank of "units" keys, an individual stepped slide being associated with and differentially settable by each bank. Each pair of "units" and "tens" slides is mounted end-to-end in a support member and slides therein for the setting movement after which movement, an actuating member moves the support member until a selected step on the "units" slide abuts against a fixed stop member so as to accurately position the "tens" slide in accordance with the combined settings of the "units" and "tens" slides. The device may be applied to micro-image projection viewers and printing apparatus in which information stored on 35 mm. film is projected on to a photo-chromic film sheet by a reducing projection system to form micro-images which may be subsequently viewed by projection and/or contact printed on to silver halide film. The micro-images are located precisely on the film by means of the above positioning device. For projection of the photo-chromic images on to the viewing screen 62, light from a supplementary source is directed through the film sheet by a pivoted mirror.

Title: Digital memory coin selector method and apparatus
IPC: G01N27/72
Filed: 1972-10-12
Abstract: 1452740 Testing coins MARS Inc 8 Oct 1973 [12 Oct 1972] 47161/72 Heading G4V A method of testing coins comprises examining a coin, producing an electrical signal having a value indicative of a characteristic of the coin and comparing the value with a value stored in a programmable memory. In the embodiment shown coins of three denominations (5c, 10c and 25c) are examined at high frequency inductive sensing stations 511, 514, the effect of the coin on the frequency of associated oscillators 521, 524 being measured, and low frequency inductive sensing station 512 associated with a bridge circuit 522. The circuit 522 will produce one pulse on one of three denomination associated output lines if the coin is authentic, Specification 1397087 is referred to in this respect. The outputs of oscillators are alternately gated into a counter 580 under the control of timing pulse generator 540 and the count level is compared by comparator 560 with the output of memory 550. Three-bit address registers 551, 554 associated with oscillators 521, 524 respectively have their outputs alternately gated into memory 550, depending on which oscillator is being sampled, to select the memory address and hence determine its output. Whenever the count in counter 580 exceeds the output of memory 550 the appropriate address register is counted up one to select the next address of the memory and the maximum frequency shift caused by the coin (and hence an indication of its authenticity and denomination) can be determined from the output of the address register Figs. 6A, 6B (not shown). A logic unit 590 receives the outputs from address registers 551, 554 and low frequency examination circuit 522 and produces signals indicative of the authenticity and value of the coin if the results of each examination are positive, relate to the same denomination of coin and have been received in the correct order. A similar embodiment Fig. 7, (not shown) includes means for modifying the results of the high frequency examinations in dependence on the results when no coin is present in order to compensate for changes in the operating parameters, Specification 1443934 is referred to in this respect. Another embodiment Figs. 2 to 4, (not shown) includes a circuit (301) for detecting the peak frequency shift of the oscillator (370), this peak value being compared with the values stored in memory (250). The circuit (301) includes a counter (320) connected to sample the output of oscillator (370) during timed testing periods, the content of the counter being transferred into a register (340) if at the end of each period the count level exceeds the content of the register. The memories may be programmed by the application of a control signal and passing a set of standard coins through the apparatus.

[Also in Division H2] A circuit including a regulating switch, e.g. a transistor VT1, which is switched "off" and "on" repeatedly, and an inductor L1, is protected against excess current conditions by means of a circuit including a resistor R3 connected between an output terminal H and a "free-wheeling" diode D1 for the inductor L1. A capacitor C2 is charged through a diode D2 by the voltage developed across the resistor on the decay of current through the inductor L1 when the switch is opened. When the current is excessive, the voltage across the capacitor C2 is sufficient to render a transistor VT2 of a Schmidt trigger circuit non-conducting so that a relay OCR releases. This relay closes its contacts OCR2 to apply a locking potential to the control circuit of the transistor VT1 to lock this transistor "off". The relay also closes contacts OCR3 to complete an alarm circuit and opens contacts OCR1 to disconnect the trigger circuit and relay.

Abstract: 1535431 Alphanumeric displays PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Nov 1976 [21 Nov 1975] 48093/76 Heading G5C In a gas discharge display system comprising one or more tubes 1, 3 in which segments or whole characters can be illuminated, where each tube includes multiple cathodes forming the segments or characters and one or more anodes, a low D.C. maintains an invisible discharge, enhanced to display selected cathodes during the duty cycle of a pulse supply to the anode(s) from pulse-shaper circuit 33 via diodes 43, 45 providing a p.d. above threshold, while on non- selected cathodes the p.d. does not exceed threshold. The duty cycle may be made sensitive to ambient light level to brighten the display in bright surroundings. Cathodes not to be displayed are raised 30 V. above ground line 7 by drive circuit 5, possibly integrated, and, e.g., comprising a decoder following the divider stages of a clock. Bridge rectifier 17, 19, 21, 23 provides from 50 Hz mains smoothed direct voltage, e.g. 310 V. across capacitor 13 via diode 31, and 100 Hz unsmoothed supply at node 29. Zener 55 maintains constant potential, e.g. 100 V., across capacitor 57, while the maximum output voltage, limited to the sum of the voltages on Zeners 55 and 53, must be higher than the highest threshold of any cathode but not more than 30 V. above the lowest threshold. At a time shortly after the voltage across Zener 53 reaches its full value, thyristor 59 is fired by charging circuit 63, 65, 67 to end the pulse, the pulse duty cycle being adjustable by resistor 63 and, if required, by light-sensitive resistor 67; variable resistor 63 may be replaced by a transistor. The low D.C. to the anodes is provided from the smoothed 310 V. across capacitor 13 via high resistors 9, 11; this current maintains ignition and reduces noise. In multi-anode tubes only one anode need be supplied with the low D.C. The pulse shaper circuit may be supplied with smooth D.C. if a pulse generator is provided.
