Abstract: 1,238,381. Drinking trough. D. C. LEEMING. 11 June, 1970 [19 June, 1969], No. 31183/69. Heading A1M. [Also in Division F2] A poultry drinker comprises a trough 17 which is supplied with water from a valve assembly 15 through a flexible pipe 12 connected to a water supply pipe 13 by a saddle connector 14 which includes a valve biased to a closed position and adapted to be opened by engagement of the flexible pipe with the saddle connector. A short tube attached to the valve body of the connector 14 is inserted into a corresponding hole in the supply pipe 13 and is clamped in position. A valve closure member 43 (Fig. 3, not shown) is urged by a spring to engage a closure seat and on engagement of the flexible pipe by means of an attached screw cap the valve is lifted from its seat and thereby opened. Attached to the other end of the flexible pipe 12 is a body member 19 of the valve assembly 15 about which is supported concentrically on a flange a spring 26 which supports on its upper end a cap 27 which by means of a screw-thread engages a neck 23 attached to the trough 17. A valve closure member 28 is urged by the spring 29 to close a valve opening 25 in the body member 19 such that when the trough 17 is filled with water its weight compresses the spring 26 and the trough neck 23 is low relative to the body member 19 and when the weight of water is reduced the neck 23 rises and a projecting pin 31 integral with the neck lifts the valve closure member 28 so that water flows through opening 25 and through holes 32 in the neck 23 to the trough 17. Adjustment of the screw cap 27 on the neck of the trough, which each have matching projections to provide audible clicks on rotation, results in an adjustment of the water level which is maintained in the trough. When the trough is stood on the ground a frusto-conical washer 34 closes the opening 25 to prevent water overflow.

Abstract: 1,265,701. Control of A.C. motors. HOLZER PATENT A.G. 28 March, 1969 [2 April, 1968], No. 16441/69. Heading H2J. [Also in Division G3] The speed of an A.C. motor 4, supplied through a switching device 3, is regulated by adjusting the frequency at which the device 3 is operated in accordance with a voltage dependent on the speed derived from a tachogenerator 5. The tachogenerator 5 provides an A.C. signal which is rectified at 6 and compared with a desired speed signal 8 at 7. The output of the comparator 7 is used to control the frequency of an oscillator 1 whose output is amplified at 2 and used to trigger the switching device 3 which may be a symmetrical thyristor such as a Triac. By means of a synchronizing signal 9 the oscillator pulses are arranged to trigger the thyristor 3 at the zero of the A.C. supply and the pulses are of sufficient length that the thyristor stays on for one full cycle of the supply. The supply to the motor is thus in the form of complete cycles at spaced intervals, the intervals varying with the error signal to maintain constant the motor speed. The oscillator 1 may be replaced by an integrating counter which counts the half-waves of the A.C. supply at a rate determined by the time integral of the voltage 10 and issues a pulse to trigger the thyristor after a number of half-waves, the number being varied in accordance with the speed error signal.

Abstract: 1,265,726. Safety harness retraction device. JIM ROBBINS SEAT BELT CO. 2 April, 1969 [29 April, 1968], No. 17137/69. Heading A3V. A seat belt retracting device comprises a support 12, Fig. 1, a spring loaded reel, a locking pawl 70, Fig. 3, for preventing the reel rotating in an unwind direction, and a disabling cam follower 60 for disengaging the locking pawl 70 upon rotation of the reel through a predetermined angular distance in the winding direction. The belt 41 is stitched around a tube 36, Fig. 5, and clipped thereto by a member 42; the tube is rotatably mounted on plastics bushes 30, 32, the former being keyed to a non-rotatable inner tube 24 and bolt 18 and being connected by a spring 35 to the bush 32 which is keyed to the tube 36. Ratchets 43, 44 are keyed at 44' to the ends of the belt clip 42, and the reel assembly mounted on the support by bolt 18, with spring 35 biasing the belt to a wound up position. A grooved cam 52 is mounted by lugs 54 on one ratchet 43, and operates a folpin 62, Fig. 3, mounted on the follower 60 having a slotted portion 64 around the bolt 18, so that rotation of the reel translates the follower 60 transverse the bolt. An over-centre spring 65 is mounted on the support at 66 and connected to the follower at 68. Cam 52 has inner and outer circular grooves 56 and 55, centered on the bolt 18 and connected by a spiral groove 58. A pawl 70 is pivoted to the support at 72, and has a pin 78 slidably engaging a slot 80 in follower 60; when the follower is in its left side position shown in Fig. 3, the pawl is held away from ratchet teeth 48 by pin 78, and the reel may be unwound partially or wholly so that a wearer may buckle the belt. The follower 60 moves to the right, Fig. 4 (not shown), during unwinding. When the follower is free from pawl 70, a time delay dash pot 81, which is compressed by a member (75) riveted (at 76) to pawl 70 when the latter is in the position shown in Fig. 3, slowly expands as air enters it through a pin hole and moves pawl 70 into engagement with teeth 48 on ratchets 43. The reel is thus locked against unwinding shortly after the belt is buckled. The spiral groove 58 is formed so that when the reel rotates through a predetermined angle in the wind direction, as on unbuckling the belt, the follower 60 operates on pin 78 and disengages pawl 70. This angle is chosen such that the reel may take up slack in the buckled belt without freeing the pawl from the ratchet, but is also chosen so that the pawl is disengaged without completely winding in the belt.

Abstract: 1290227 Transmitting information from a remote to a central station TAMURA ELECTRIC WORKS Ltd and Y HONDA 3 March 1970 [3 March 1969] 10210/70 Heading G4H A system for transmitting information from a remote to a central station comprises a digit wheel 150 at the local station, the digit wheel having fixed to one side a number of permanent magnets which represent in a binary coded form the decimal digits on the digit wheel and which co-operate with read-out means 151-154, each including a resonator, and oscillators 10-13 at the central station for supplying a different frequency # 10 -# 13  to each of the resonators so that a resonator is caused to resonate when a magnet on the digit wheel is positioned opposite the resonator. The magnets on the digit wheel are positioned to provide a Gray coded representation of the decimal digits on the wheel. When contacts 141, 143 of a switch 14 are closed, the four frequencies # 1 -# 13  are fed to the resonators and since only the resonators adjacent a magnet provide an output signal, a combination of frequencies uniquely representing the position of the digit wheel is fed to filters 16-19 when contacts 142, 143 of the switch 14 are closed. A converter circuit 20 converts the binary coded signal back to a decimal inclination which is displayed on a digital display device 21. The resonators may comprise tuning forks or reeds with magnetostrictive, piezoelectric or electrostrictive input elements attached thereto. In a modification the read out means are connected in series with a variable frequency oscillator and a current detector. A modification in which four circuits each comprising a fixed frequency oscillator, one of the read-out means and a detector are connected in parallel is also described. An additional oscillator may be provided to perform a parity check on the read-out signals or to check the entire system.
