Title: Improvements relating to a Regenerative Telegraph Repeater.
IPC: H04L25/04
Filed: 1966-10-06
Abstract: 1,157,529. Telegraphy. KOKUSAI DENSHIN DENWA K.K. 6 Oct., 1966 [8 Oct., 1965], No. 44749/66. Heading H4P. A telegraph regenerative repeater comprises a sampling clock pulse generator 110 which is enabled by a pulse from detectors 109 or 108 in response to a mark-space or a space-mark transistion respectively in the received signal at 101. The clock pulses centre sample at 104 the received signals, the samples operating a bi-stable circuit 105 to provide undistorted telegraph output. When the generator 110 is enabled the detectors 108, 109 are inhibited. The clock pulses are counted by counter 111 which normally gives an output pulse to stop the generator after input of 7 clock pulses, i.e. after sampling one telegraph character. However, if the generator is enabled by a spacemark transistion from detector 108 the counting scale is changed to 2. Use of the two scales of counting permits correct regeneration of 7 or 7¢ bit start-stop telegraph characters and of the various connection control signals such as long space and dialling pulses.

Abstract: 1,150,688. Mechanical garages. S.A.R.L. BIANCHI FRERES & CO. "BOXDAD". 3 Oct., 1967 [4 Oct., 1966; 7 March, 1967], No. 45075/67. Heading B8E. A trolley for transporting vehicles, e.g. in a multi-storey garage, comprises support members A extending laterally of the trolley and mounted for longitudinal sliding movement such that with the trolley beneath a vehicle, when the members A are moved outwardly, some abut the vehicle wheels and others engage beneath parts of the wheels. The trolley includes a lower part C supporting an elevator E carrying the members A which slide in guides 3, 3<SP>1</SP> and which are biased by springs 4 to the outermost position. The members A are moved inwards by bars 6 extending longitudinally of the trolley, the bars 6 engaging stops 5 on the members A. The latter are disposed adjacently in sets separated longitudinally of the trolley, the lengths of each set ensuring that vehicles having differing wheelbases can be engaged. The elevator E is moved vertically by cams 7 on shafts 8 driven by an electric motor. For moving the bars 6, these may have tapped holes engaged by laterally extending screwed bars rotated by an electric motor. The chassis may be raised by pneumatic or screw jacks. In a second embodiment, Fig. 7, the support members A are slidably mounted in members 16 driven laterally by threaded rods 17. In operation the members 16 are moved outwards until the members A engage the vehicle wheels and until the members 16 are pressed against the inside of the wheels when they stop automatically by the action of torque-limiter nuts 20. The latter are pivoted about vertical axes so that the members 16 may take up positions which are not parallel with the axis of the trolley, thus accommodating themselves to the position of the vehicle wheels. When the members 16 are moved inwardly to release the vehicle wheels the members A which have engaged the sides of the wheels are moved outwardly to their original positions by engagement of their inner ends with a member located on the longitudinal axis of the trolley. The members 16 may be moved laterally by pneumatic or hydraulic jacks and similar jacks may be used for the trolley elevator.

Filed: 1974-10-25
Abstract: 1482935 Selective signalling NATIONAL PUBLIC RADIO 25 Oct 1974 46340/74 Heading G4H In a method of alerting individual member stations 16 connected to the master station 10 of a radio network which transmits a common audio programme to the member stations over a certain channel, an alerting signal consisting of one or more non-musical tones each having a predetermined amplitude frequency and duration is transmitted over the same channel. Signals received at a member station are evaluated in terms of amplitude, frequency and duration against predetermined standards and a predetermined control signal produced in response to an acceptable evaluation. The alerting and programme signals are sent from the master station to the member stations by land line. Tones are detected at a member station by a "netcue" receiver which incorporates tone evaluation circuits 28 each including a phase comparator 36 and voltage controlled oscillator 40 forming a phase locked loop. The VCO 40 has a very narrow bandwidth centred on the frequency to be detected. The comparator normally delivers a positive voltage to point 38, but this voltage falls to zero when a steady frequency tone is detected. The normal positive voltage is applied to a diode capacitor transistor arrangement 44, 52, 48 which tests the duration of the received tone by using the zero output at 38 to allow the capacitor 52 to discharge. If the capacitor discharges the transistor 48 switches to operate a relay in the decode logic 56. Amplitude of the tone pulses is determined by a threshold circuit 27 in advance of the frequency and duration evaluation.

Title: Variable drive for a stuffer crimper for crimping yarns
IPC: F16H15/08
Filed: 1970-09-30
Abstract: 1319606 Crimping yarns JOSEPH BANCROFT & SONS CO 30 Sept 1970 [3 Oct 1969] 46589/70 Heading D1F In a stuffer-box crimper, a sensing member responsive to change in the level of a core of crimped yarn in the crimping chamber initiates a corrective adjustment and operation of a variable drive which so controls the direction and speed of feed or winder rolls as to maintain the core at a set level. In the apparatus shown in Fig. 2, when a solenoid 34 is deenergised a spring 33a holds an idler roll 30 in an advanced position towards the centre of the disc 25 whereby the drive transmitted from a roll 28 (mounted on a drive shaft 23 which may be common to a number of crimping heads) to disc 25 thence by shafts 20, 21, to the feed-in rollers of the crimper 10 is at normal rate: when the solenoid 34 is energised by closure of contacts in an actuating circuit by a slug 40 due to a rise or fall in the level of the crimped yarn in the crimping chamber, the idler roll 30 (in weight-loaded contact with both roll 28 and disc 25) is retracted or advanced radially of disc 25 thereby to decrease or increase correctively the speed of rollers 14, 15. In the apparatus of Fig. 4, the drive to the crimper feed-in rolls by shaft 51 is effected from the driving roll 54 to a tapered roll 50 through idler roll 55 in weight-loaded contact therewith and which is positioned, as in the first embodiment, by a spring 67 or an energised solenoid 58 when a corrective speed adjustment (as determined by the level of slug 40) is to be applied. These two embodiments effect corrective speed control of feed-in rollers but the mechanism may be applied to control the speed of the crimped yarn wind-up apparatus, e.g. a winding drum, Figs. 7 and 8 (not shown) a spindle, the speed of the feed-in rollers then being constant. Idler rolls may be eliminated so that driven members are rotated directly by driving rolls keyed to the drive shaft to permit shifting therealong in response to movement of slug 40. Solenoid(s) may be replaced by reversible motors.

As shown, a tube 12 of welded P.V.C. attached to a collapsible bag 8 by adhesive is positioned in a wall-mountable dispenser and located by pins 21, 22 passing through holes 18, 19. The bag 8 may be pressed by a weight 9 or a spring and the end of the tube 16 is severed by cutting along the line 16a. Upon depression of the lever 30 against the action of a return spring 32 to deliver a measured quantity the rollers 33, 34 swing about a pivot 31 in the clockwise direction to seal the upper end of the tube against the upper end wall of the chamber 26 and unseal the lower end of -the tube from the lower end wall 36; with the lever 30 fully depressed the upper end of the tube is bent and flattened and the lower end of the tube is open, the tube resting against the curved surface 38. If desired, the lower roller 34 may be omitted; in such case the lower end of the tube automatically folds to seal it when the tube is inflated. Instead of a bag 8 a reservoir can be formed in the frame of the dispenser. The lever 30 may be operated remotely through mechanical, electrical or pneumatic means. The dispenser may also be applied to the dispensing of gaseous products.

Filed: 1966-10-21
Abstract: 1,198,798. Fuel injection pumps. C.A.V. Ltd. Oct. 9, 1967 [Oct. 21, 1966], No.47246/66. Heading F1A. In a radial cylinder rotary distributer type fuel injection pump inward movement of the pistons 13 causes liquid to move a valve 21 to the right against the action of a spring 22 and so cause displacement of liquid from the spring chamber to an outlet port 19 which at this time is in alignment with one of the outlet passages 20. Further movement of the valve connects the pump cylinder through longitudinal and cross bores in the valve to the spring chamber and outlet port 19. The end of the discharge stroke is followed by a slight retraction of the pistons 13 so that the valve 21 moves to the left relieving the pressure in the outlet passages; this period of retraction is followed by a dwell during which the cylinder and valve bore are connected both to the inlet port 26 leading through a governor controlled throttle to the outlet of the feed pump, and to a drain passage 30 at low pressure. The drain passage then closes followed by closure of the delivery passage 20 and outward movement of the pistons 13. The pressure in the spring chamber and outlet port 19 is then adjusted by one of the ports 32 which comes into communication with a port 33 leading to the feed pump outlet passage 15. The delivery in relation to speed is adjusted by means of a spring loaded piston 41 in a chamber 40 which is brought into communication with the spring chamber and outlet port 19 by means of a port 46 with which one of the ports 32 communicates when outlet port 19 connects with an outlet passage 20. Movement of the piston 41 is limited by a stop, the position of which is adjusted in accordance with feed pump outlet pressure which is speed sensitive. Subsequently the chamber 41 returns liquid to the spring chamber through a port 46. The pump cam ring may be angularly-adjustable to vary timing.
