Title: Method and device for reducing yarn defects on an open end spinning system
IPC: D01H4/44
Filed: 1968-12-03
Abstract: 1,236,038. Stop motion. TORAY INDUSTRIES Inc. 3 Dec., 1968 [12 Dec., 1967], No. 57436/68. Headings DID and D1J. A device for stopping spinning in an openend device upon the occurrence of a thick part in the produced yarn comprises a device such as a tube 3c through which individual fibres are carried in an air flow to the chamber 4, a duct 10b whereby compressed air is fed to tube 3c to produce the air flow, an electromagnetic valve 10a in duct 10b and means downstream of chamber 4 to detect a thick part in the yarn and cause valve 10a to be actuated to stop the supply of compressed air and thus halt the spinning process. As shown a slit is provided between plates 9a, 9b spaced so that a thick part is caught and the yarn broken; this allows a biased feeler 8b to swing sideways, and operate a switch which causes valve 10a to be operated. A suction nozzle 21 catches the loose end of yarn and prevents it being drawn back into the spinning chamber by centrifugal force. A second biassed feeler 8c is provided at the exit of the spinning chamber to stop the supply of compressed air should the yarn break or become weak and slack in this region. In Fig. 2 not shown the slit flats (19a, 19b) are inclined to the yarn so that when a thick part engages the slit the yarn is deflected sideways to shift a feeler (8b) and close valve 10a. In Fig. 4 not shown the slit is at one end of a plate pivoted about a horizontal axis. When a thick part engages the slit the plate is pivoted against a biassing spring thus releasing a switch which closes valve (10a).

Abstract: 1,211,052. Wave-energy position finding. FRIED. KRUPP G.m.b.H. 4 Dec., 1968 [5 Dec., 1967], No. 57584/68. Heading H4D. The sound wave emissions from, e.g. a submarine 13 are received at buoys 11, 12 which produces signals representative of angles # 1 , # 3  respectively, the buoys also produce signals representative of angles # 2 , # 4  respectively from sound or radio waves from an aircraft 14, and the signals are transmitted to the aircraft which is flown such that # 1  = # 2  and # 3  = # 4 : the aircraft is then above the submarine. On a buoy, a transducer 21 of the kind described in U.S. Specification 3,290,642 produces voltages representing the sine and cosine components of the bearing and a non-directional voltage, the three voltages are fed to a switch and synchronizer (24, Fig. 2 (not shown)) also fed via a switch (26) and a frequency-changer (25) with voltages representing the sine and cosine of the radio bearing of the aircraft, and a non-directional voltage utilizing a crossed-frame aerial (22) and a non-directional aerial (23). The frequency-changer transforms its input voltages to the frequency range of the transducer, the output voltages of the transducer and the frequency-changer being applied to a common bearing calculator (27) which signals the # values to the aircraft. On a buoy the relating of the bearings to North utilizes a compass-stabilized transformer, Fig. 3 (not shown). Rotation or displacement of the buoys has no effect on the system. The buoys may be dropped by the aircraft which is steered before the release of the second buoy to secure maximum accuracy in position location. The noise from the aircraft may be utilized on a buoy for determining aircraft bearing. The invention may be used to indicate to an aircraft the positions of acoustic responders (which then take the place of submarine 13).

Abstract: 1472548 Thermal regenerators NOEL PENNY TURBINES Ltd 12 Dec 1974 [14 Dec 1973] 58124/73 Heading F4K In a seal assembly for a rotary regenerator 7 including peripheral and cross arm seals located between the end faces of the matrix 7 and a surrounding housing 8 (9, Fig. 2) each seal comprises a backing plate 2, or 4, urged into engagement with the adjacent end face of the matrix by an axially compressible resilient member 1 or 3 the interior of which is in communication with an annular chamber 13 supplied with compressed air and surrounding the matrix. The peripheral and cross arm backing plates 2, and 4, are formed separately so that they can expand independently during heating. Each arcuate backing plate 2, has outwardly extending lugs 20 at its ends which co-operate with a respective end of the cross arm backing plate 4. The distance between the lugs 20 is less than the length of the cross arm backing plate 4, whereby the cross arm backing plate 4 is compressively stressed between the lugs 20 on each arcuate backing plate 2 under cold conditions and the length of the cross arm backing plate 4 is such that the backing plates 2 and 4 are substantially stress-free under hot working conditions. The lugs 20, which have ears 21, are located between inwardly extending circumferentially spaced walls 14 on the housing 8, which walls 14 serve to prevent the seal assembly from rotating in the housing. The arcuate backing plates 2 are made elliptical with the major axis thereof being at right angles to the cross arm backing plate 4 and the ellipticity such that under hot working conditions the plates 2 will become circular. The surfaces of the backing plates 2 and 4 engaging the matrix 7 are formed with respective rubbing layers 6 and 5. As shown the resilient members 1 and 3 of each seal are secured together to provide a continuous surface by bending one side wall of each peripheral member 1 around the adjacent rim portion 10 of the cross arm member 3. Alternatively (Figs. 6 and 7, not shown) the resilient peripheral and cross arm members 1 and 3 may be joined together by welding.

Title: Lubricating device for pneumatic tools
IPC: B25C1/04
Filed: 1971-12-17
Abstract: 1344659 Lubricator; valves A MATHES 17 Dec 1971 [22 Dec 1970] 58743/71 Headings F2A and F2V A lubricating device which is located in the compressed air conduit of a pneumatic tool comprises an air pressure chamber and a surrounding oil chamber and an opening from the oil chamber to the air chamber which is closed by a valve. In operation air is fed to the air chamber 2 via a connection 14 and flows through a filter 15. The air moves a valve against a spring 18 thereby opening the passage to the tool and uncovering the connection between the air and oil chambers. Oil flows from the oil chamber and is entrained in the flow of air to the tool. The valve has a valve stem which moves in a sleeve 21 which contains the spring 18. On compression of the spring air is expelled from within the sleeve through a non-return valve 9. On stopping of the tool by cessation of the air flow, excess air on the downstream side of the valve flows back past the valve by deflecting a flexible portion 7 of the valve head. The flexible portion is permitted to deflect only in one direction by rigid portions of the head. Air under pressure passes into the oil chamber so that the pressures in the air and oil chambers are equalized. The return of the valve to its initial position is retarded by the low pressure within the sleeve, thereby allowing time for the pressures to become equalized. When the valve resumes its initial position, the oil chamber is closed by a valve cone 6. The oil chamber has a transparent inspection port 13 and a filling plug 12. A filter 17 may be interposed in the passageway between the oil chamber and the air chamber. The sleeve may be provided with a helical groove which receives a cam carried by the valve shaft so as to impart rotational movement to the valve shaft during its longitudinal movement.

Title: An adapter
IPC: G06F13/38
Filed: 1969-12-08
Abstract: 1,249,536. Data transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 8 Dec., 1969 [14 Jan., 1969], No. 59766/69. Heading H4P. In a system having at least two speeds of transmission, each set of data is preceded by at least one character having a determined number of level transitions per unit time which is detected at a receiver and compared sequentially with a number of locally generated signals until the speed is identified. Audio signals on a line 12 are converted to binary signals in a unit 11 and amplified at 14. A clock 20 generates one of a series of frequencies on line 21 which actuate a monostable multivibrator 26 passing pulses to a counter 51, also timing pulses T1-T3, one for each oscillator cycle commencing at the start of each bit interval. Clock 20 is activated by the first signal transition on line 15 the circuit being previously set by a signal on line 29 when the receiver is switched to line which latches circuit 30 and sets counter 31 to zero, also through OR gate 32 sets latch 33 to the rest condition. As the first signal is a zero, input to AND gate 36 is low while the complementary signal from inverter 37 to AND gate 38 is high. A pulse on line 27 will pass through AND 38 to set latch 39 to zero. At the succeeding time T1 the signal on line 22 gates AND 42 to pass the signal if latch 39 is zero and latch 33 is at " ONE " or will gate AND 43 if latches 33, 39 are reversewise. Output of AND gates 42, 43 are combined in OR 44 which provides a signal on line 45 when the states of latches 33, 39 are different, i.e. when there is a data transition. The number of transitions are counted by counter 31. At time T2 after data transitions, if any, have been counted, the state of latch 39 is transferred to latch 33. AND gates 48, 49 receive mark and space outputs of latch 39 when gated by the T2 signal on line 23 transferring the setting of latch 39 into OR gate 32 on the mark or space input to latch 33. To determine the incoming speed pulses on line 27 are counted into counter 51 which are recognized by a decoder 52 when the count reaches 8. AND gate 54 receives a signal from decoder 52, also an output from latch 30, a T2 signal on line 23, and a signal from NOT gate 56, hence generates an output which resets latch 58 which transfers the output from line 59 to line 60 this disconnecting the high speed oscillator and energizing the low speed oscillator hence the process is repeated. At time T3 after counter 51 has reached a count of 8 latch 30 is reset by signal T3 to AND gate 64 which also resets AND gate 54 to prevent consequent functioning of latch 58. Or gates 57, 61 can be activated to select an oscillator for other functions (not disclosed). A greater number of oscillators than two may be provided and switched in sequence.

Filed: 1971-12-23
Abstract: 1360480 Superconductor devices COMPAGNIE GENERALE D'ELECTRICITE 23 Dec 1971 [7 Jan 1971] 60085/71 Heading H1K A superconductor switch comprises a superconductive-winding and a control winding wound coaxially in which the number of superimposed turns in one of the windings increases from one end to the other. This enables the superconductive load winding to be switched from its superconductive state to its normal state according to a desired time dependent law. The switch is utilized to control the charging, storage and discharging of a superconductive storage winding. As shown, Fig. 1, a cylindrical superconductive load winding 1 is provided with two tapered control windings 4, 5. When energized the control winding produces a magnetic field which is larger at one end than at the other so that as the control current increases the load winding is progressively switched to the normal state, its resistance increasing according to a law which depends on the distribution of turns in the tapered winding and on the waveform of the energizing current. In a second embodiment, Fig. 3 (not shown), the load winding is tapered and the control windings are uniform. In a further embodiment, Fig. 4 (not shown), all of the load and control windings are tapered. The load winding may comprise turns of multi-strand Nb 40% Ti or Nb-Zr alloy or single wires or tapes of Nb 3 Sn. The control windings are of Cu and the switch is enclosed in a magnetic screen 6, e.g. of Cu.

Abstract: 1,208,500. Endless conveyers; packaging glass tubes. CORNING GLASS WORKS. 18 Dec., 1968 [26 Dec., 1967], No. 60168/68. Headings B8A and B8C. [Also in Divisions F2 and G1] Apparatus for automatically inspecting, sorting and packaging glass tubes 10 comprises conveyers 12, 18 which advance the tubes to star wheels 20 at each end of the tubes. The star wheels deliver the tubes to chucks 24 which grip the tubes whilst gauging devices examine the ends of the tubes. Satisfactory tubes drop from the chuck between guides 50, 52 on to a supply rail 44 where they are moved by conveyers 116, 48 to a stacker supply shelf 120. Unsatisfactory tubes cause the gauge to supply a signal to the guides 50 which move towards the guides 52 thereby causing the rejected tubes to be delivered to a conveyer 56. A by-pass gate 16 may be operated to direct the tubes directly from the conveyer 12 to the conveyer 56 via a conveyer 27. Three switches (118), Fig. 13 (not shown), are located above the rail 44 so that if a build up of tubes occurs, thus causing each of the switches to be simultaneously actuated, a signal is transmitted to the guides 50 to divert following tubes to the reject conveyer 56. The conveyer 48 has spring loaded pegs 46 so that in the event of a tube build up the pegs pass over the tubes. Eight jigs 122 are intermittently advanced by a chain 124 to the shelf 120 where they are automatically filled with seven rows of nine tubes. The jigs then advance to a capping station where end caps 136 are placed on the ends of the stack of tubes. The end caps are stored on four horizontal guide rails 138 and are advanced singly by a cylinder 150 having suction cups 152. A photo-cell 146 detects the presence of a cap to prevent further forward movement of the supply of end caps by a motor 142. The cylinder 150 is longitudinally movable and is rotated about an axis 154 so that the caps, which have four flaps supported by arms 156, are placed on the ends of the stack of tubes. End cap brackets 158 are lowered around each end cap to maintain the caps on the stacks before the bundles reach a station where they are tied with string. After tieing, the bundle is ejected by a bundle ejector to a conveyer 166.

Abstract: 690,964. Synchronous machines. HACKBRIDGE & HEWITTIC ELECTRIC CO., Ltd., and WELLS, R. Jan. 2, 1952 [Jan. 3, 1951], No. 229/51. Class 35. [Also in Group XXXVII] A synchronous motor 10 of the non-salient pole type has its D.C. winding 13 supplied through a grid-controlled rectifier 18 from an auxiliary alternator 21 which is driven by the motor, the grids of the rectifier being supplied from the main A.C. source 12 through a phaseshifter 23. When a change-over switch 16 is moved to the starting position the winding 13 is connected to rheostat 15 and the negative and positive terminals of a grid bias unit 24, which comprises a rectifier and a mainsconnected transformer, are joined respectively to the cathode 17 and to the star-point of the phase-shifter. The motor thus starts as a wound rotor induction motor, the rectifier 18 being independent of the relative phasing of the anode and grid voltages whereby the rectifier is able to provide a maximum current when it is switched into the motor excitation circuit. The actuation of the switch 16 to its other position connects the cathode 17 to the phaseshifter 23 and also to the rheostat 15, so that the unit 24 is rendered inoperative and the rectifier 18 supplies the winding 13 for synchronous running. If the load angle of the motor increases the phase position of the anodes of the rectifier 18 is retarded with relation to the constant grid phase position, so providing a compensating increase of motor excitation. When the motor is of the salient-pole type, Fig. 4 (not shown), the excitation of the D.C. winding is provided by a separate source after the motor has been started and until synchronism is attained, whereupon the gridcontrolled rectifier is substituted for the separate source.
