Title: Improvements in fluid control devices
IPC: F15C1/08
Filed: 1963-10-22
Abstract: 974,997. Controlling fluid flow. GENERAL ELECTRIC CO. Oct. 22, 1963 [Nov. 8, 1962], No. 41628/63. Heading G3H. In a pure fluid amplifier in which gas or liquid issuing from a nozzle 14, Fig. 1, flows to either of a pair of outlets 22, 23 in response to signals from control nozzles 15, 16, a pair of vents 35, 36 interconnected by a conduit 40 prevent the build up of excessive back pressure in the outlets which are connected for the actuation of a valve 25. The degree of back pressure attained is adjustable by a valve 42. The formation of walls 19, 20 is such that the fluid passing to an outlet 22 or 23 tends to continue to do so by boundary layer action, and this action is enhanced by the interconnected vents 35, 36 and by the provision of a recess 43 which produces a vortex. The recess 43 may, alternatively, be of semi-circular or triangular form. In a modification, the angle between each outlet 22 or 23 and a wall 37, 38 of each vent may be obtuse instead of acute, as shown, to improve stability. In a further modification, fluid issuing from a nozzle 104, Fig. 5, is deflected towards either of outlets 110, 111 in accordance with the difference of momentum between control jets issuing from nozzles 105, 106, and a portion of the deflected jet passing through a vent 112 or, as shown, 113 passes through the conduit 120, which has baffles 121, 122, to emerge at 114, as shown, or 115 to assist the deflection of the main flow.

Title: Remote control system for self-propelled, driver carrying vehicles
IPC: A63G25/00
Filed: 1967-09-14
Abstract: 1,239,925. Inductive control of vehicles. SUPERCAR CO. (COVENTRY) Ltd., and J. M. BENTLEY-BEARD. 14 Nov., 1968 [14 Sept., 1967], No. 41966/67. Heading H4U. Inductive control means are provided for controlling the starting and/or stopping, or the maximum speed of a plurality of self-propelled vehicles operating within a predetermined area or along a predetermined track. In one embodiment for controlling battery-driven vehicles in an amusement park, a transistor oscillator feeds a loop extending around the track, a timer switch being connected in series with the oscillator. The electric motor of the vehicle is operated via a main relay under the control of the driver. Signals from the loop are picked up by a receiver on the vehicle and operate a control relay which closes a contact in the main relay circuit to make the driver's control effective for a period determined by the timing switch. Alternatively, the loop may transmit coded " start " and " stop " signals and the vehicle is provided with means to discriminate between the two signals. In a further arrangement, Figs. 4 and 5, internal combustion engine powered vehicles which circulate around a track are controlled. A loop 35 extends around the track and a loop 32 extends across the track and either loop may be energized by a transmitter 36 via a switch 37. Each vehicle has a receiver 40 operating a control relay 2CR having normally open contacts 2CR1 in the circuit of a main relay 2MR. Initially the relays 2CR, 2MR are not energized and the vehicle is driven normally until a signal is received by receiver 40 to energize relay 2CR. This causes relay 2MR to operate and hold over contact 2MR1, contact 2MR2 bring- ing into operation a governor to restrict the speed of the vehicle so that it may be stopped. In one arrangement, all the receivers 40 respond to the same frequency and a vehicle is stopped by energizing loop 32. If it is required to stop all the vehicles simultaneously the loop 35 is energized. Alternatively different frequencies or modulating signals may be used for each vehicle.

Title: Speed and phase control system for a signal reproducing apparatus
IPC: H02P29/00
Filed: 1974-09-30
Abstract: 1484715 Automatic control of speed SONY CORP 30 Sept 1974 [1 Oct 1973] 42388/74 Heading G3R In a speed-control system for use in video tape apparatus, the control of speed and phase of the rotary tape read head uses a counter having an initial count dependent upon tape speed and counts clockpulses for periods dependent upon the head speed. The system is such that the rotary head control is independent of the speed of the tape when recording. In the embodiment, control pulses recorded on the tape in positional relationship with parallel oblique data tracks are selected to form a pulse train CTL, having a frequency dependent upon tape speed. The pulse train CTL is fed to counters 33, 34, 35 which count clockpulses CP for the duration between CTL pulses, the count thus achieved being held and inverted at 44 to 55, to form an initial count for counters 21, 22 and 23. The clockpulses CP are counted for the interval between pulses in a train PG, which has a frequency proportional to head speed. The resultant count is passed via D-A converter 29 to provide a voltage Is dependent upon the speed of the rotary head but independent of the speed of the tape at the time when the control pulses were recorded thereon. The signal ls is used in a rectroactive speed-control system to control the head speed and phase, relative to the oblique data tracks, e.g. by using a brake.

Title: Improvements in or relating to the treatment of yarn
IPC: D02J1/08
Filed: 1964-10-20
Abstract: One or more travelling, "twistless", multi-filamentary yarns are treated by a gas stream to produce a tangled, optionally bulked, looped and/or doubled, yarn the filaments of which are so intertwined and bundled that they can be further processed and the coherency of the bundles is ensured with or without added twist e.g. of 40 turns per metre.  In a tangling device, the untreated yarn passes through a yarn channel into which a gas supply channel discharges eccentrically and through which compressed air is blown against the yarn, part of the air stream flowing through the yarn channel in a direction opposite to the yarn movement.  Yarn is supplied and discharged to and from the channel at a distinct angle thereto just outside the channel.  The supply speed exceeds the discharge speed by at least 3%.  The yarn is in contact with the wall of the yarn channel at the inlet and outlet ends at opposed points.  The first point is on the same side of the longitudinal axis of the yarn channel as the eccentricity relative to the yarn channel of the gas supply channel and the other point is on the opposite side thereof.

Abstract: 1437805 Radar; pulse thresholding circuits CHRISTIAAN HUYGENSLABORATORIUM BV 12 Sept 1973 [26 Sept 1972] 42896/73 Headings H3T and H4D Distance between two stations is determined by emitting a carrier interrupted a number of times from the first station, detecting at the second station each interruption and introducing a similar interruption in the carrier emitted by the second station, and measuring at the first station the period between corresponding emitted and received interruptions. A characterizing signal may be emitted by the first station prior to interruption. In the embodiment a common transmit/receive aerial is utilized at the first station and to eliminate the effects of interference at the edges of an interruption the reception of signals is inhibited during a period equal to the duration of the characteristic signal, the duration of an interruption and an interval corresponding to a minimum distance range plus inherent receiver delay; at the other station a gate eliminates interference due to crosstalk in the common transmit/receive aerial. Pulse thresholding circuit, Figs. 3, 4.-To ensure accuracy of distance measurement with varying signal level a threshold level is produced as follows: transistors T 1 , T 2  are so biased that equal currents pass through them and R 3  when the input signal e in  is continuously absent, and by selecting R 1  to be 2R 2  the voltages across R 1 , R 2  are equal in that absence. When an input signal is present the signal component e 1  will be twice that of e 2 , the latter being the threshold voltage. Voltage e out , partly determined by a clamping diode D 4 , will normally be substantially zero but during an interruption in e in  a positive output pulse appears.
