Title: Improvements in and relating to electric measuring indicating or control apparatus
Inventor: SMITH ROYSTON GEORGE
IPC: G01F23/44
Filed: 1964-05-08
Abstract: 1,105,526. Liquid level indicators. K. D. G. INSTRUMENTS Ltd. 9 Aug. 1965 [8 May, 1964]. No. 19370/64. Heading G4H. The value of a variable is indicated by a transducer which generates an electric signal representing the variable, the signal being transmitted over a line to an indicator at a receiving station, the energizing current for the transducer being fed over two lines from the receiver station through a variable impedance used for calibrating the apparatus. The transducer comprises a float 3 in a tank 1 driving an endless tape 4 the upper pulley of which controls switching units 8, 9 and 10 representing successive decades. Each switching unit comprises a rotating magnet adapted to operate one of ten reed switches Sa-Sj to connect the corresponding tapping of potentiometer to Ra-Rj to the signalling line L3. The potentiometer is supplied over lines L1, L2 from the receiving, station. Variable resistors VR2, VR4 are provided in the supply lines and VR5 in the signal line. A stabilized voltage supply to lines L1, L2 is given by Zener diode D1. Another Zener diode D2 gives a stabilized voltage at the other side of the indicator D from the signal line L3. To calibrate the apparatus, the indicator is first disconnected by moving switch SA to the " 0 " position. The mechanical zero adjuster is then moved until the zero digit is properly positioned on the screen. Resistors VR2, VR4, VR6 and VR5 are moved to maximum, zero contact Sj is closed and switch SA moved to read position (R). Resistor VR1 is adjusted to bring the zero to the proper position. Contacts Sa are then closed, corresponding to digit 9 and resistor VR5 adjusted until the 9 digit is properly positioned. These adjustments for 0 and 9 are repeated until both are correct. Switch SA is then moved to the test position and a reference voltage from potentiometer VR3 is adjusted until the digit 9 is properly positioned on the indicator. The ganged resistors VR2 &c. are reduced according to the line resistance RL1, RL2 when the apparatus is installed.

Title: Improvements in fluid pressure control systems
IPC: G05B11/50
Filed: 1958-06-18
Abstract: 897,699. Fluid-pressure servomotor-control systems. SAMSON APPARATEBAU A.G. June 18, 1958 [June 18, 1957], No. 19548/58. Addition to 794,108. Class 135. In a fluid-pressure servomotor control system as described in the parent Specification in which a feed-back connection between the stem of a diaphragm-actuated valve and a pressureresponsive device subjected to a variable control pressure includes a torsion-rod, the relay valve actuated by the pressure-responsive device to control the pressure in the diaphragm chamber, comprises a pair of nozzles 29, 30, Fig. 5, normally closed by a nozzle closure flap tiltable about one or other of the nozzles to open one or other of the nozzles. The flap 31 is supported on a substantially U-shaped torsion leaf-spring 34, Fig. 4, mounted on a pivotally-mounted control shaft 35, which carries a lever 38, connected by a wire 39, Fig. 2, to a further lever 7. The lever 7 is secured to the base-plate 9 of a bellows unit 10 to which a variable control pressure is admitted through a pipe-connection 13, and to one end of the torsion-rod 2 in the form of a flat band-spring mounted in a tubular extension 1 of a housing 4 enclosing the various parts. The other end of the torsion-rod 2 is adjustably connected to a lever 20 which in turn is operatively connected to the valve stem of the diaphragmactuated valve. The outlets from the nozzles open into a chamber 28 connected to the diaphragm chamber, one of the nozzles being connected to a supply of compressed air and the other to atmosphere. Thus, depending upon the pressure in the bellows 10, the shift 35 rotates in one or other direction to vary the pressure in the diaphragm chamber and hence the flap 31 to control the amount of opening of the diaphragm-actuated valve. On movement of the valve stem, the levers 20, 7 and the torsion rod 2 re-adjust the position of the shaft 35 and thence the flap 31 with respect to the nozzles until equilibrium is restored.

Title: Improvements in or relating to cable controlling devices
IPC: B66D1/58
Filed: 1966-05-05
Abstract: 1,146,073. Winches. UNITED SHOE MACHINERY CORP. 5 May, 1966 [6 May, 1965], No. 19917/66. Heading B8B. [Also in Division F2] A winch for a cable 24 comprises a drum 10 rotatably supported on a tubular beam 16 rigidly interconnecting the apices of generally A-shaped side frames 12, 14, which are anchored to a supporting structure and driven via gearing including a cage member 80 yieldingly displaceable within the drum to limit the winch torque. The winch is moved into its operating position via a handle 28 and rollers 36 on each side frame whereupon the rollers are raised by means of toggle linkages 38, 42, 44 and the winch becomes supported on pads 34. The drum 10 has spiral fluting to accommodate a double lay of cable 24 guided on to and from the drum by a casting 220, the latter being moved each away along a driven shaft 222 having a continuous right- and left-hand helix thereon which engages a follower on the casting. The screw 222 is driven at a speed proportional to that of the drum 10. Underwind and overwind limit switches 250, 252 are actuable by an adjustable plate 254 on the casting 220, to shut off the winch motor and automatically apply a brake thereto. On leaving the drum, the cable passes between vertical guide rolls 238 and a pair of horizontal pulleys (216, 218), Fig. 5 (not shown). The pulley (216) is rotated by a one-way driven bar 212 to tension the cable as it leaves the drum 10. The drum is driven by a reversible electric motor which through a gear train drives a shaft 70 coaxially mounted inside the tubular member. A sprocket 74 on the shaft 70 drives a sprocket 78 mounted in the cage 80. The sprocket 78 drives internal teeth 84 of a harmonic drive wave generator 86 having an elliptoidal outer surface. The latter engages through an elliptoidal ball race, one end of a flexible spline 100, the other end of which is fixed to the side wall of the cable drum, Fig. 6 (not shown). Teeth on the exterior of the flexible spline engage at diametrically opposite points on the major axis of its elliptoidal form with internal teeth on a rigid circular spline member, coaxial with the member 16 and selectively rigidly connectible thereto by lever 126, Fig. 1. When the circular spline member (106), Fig. 6 (not shown), is rigid with the tubular member 16 it acts as a reacting member for the flexible spline 100 and the drum 10 is power driven. The cage 80 has a limited rotation about the member 16 against a pre-set spring pressure, the amount of rotation being proportional to the tension in the winding cable. Three micro-switches each arranged to be operated at different predetermined amount of rotation of the cage 80 are selectively coupled into the electric circuit of the drive motor and its brake, such that at a predetermined cable tension the motor is de-energized and braked.
