Title: Control apparatus for metal vapour discharge lamps
IPC: H05B41/18
Filed: 1972-11-17
Abstract: 1446549 Automatic control of temperature THORN ELECTRICAL INDUSTRIES Ltd 31 Dec 1973 [17 Nov 1972] 53260/72 Heading G3R A control apparatus for a metal vapour discharge lamp, e.g. sodium, cesium, mercury vapour or for metal halide discharge lamps wherein materials in the lamp fill tend to condense on the envelope wall below a minimum lamp temperature, is arranged to control a fan motor 13, Fig. 3, to control the flow-rate of cooling air applied to the lamp in response to radiated power output of the lamp or a function thereof whereby to maintain the lamp wall temperature substantially constant. In Fig. 3, the lamp 11 current is adjustable by an impedance 16 which is mechanically linked by a rod 28 to the slider of the fan motor speed adjusting resistor 24 so that if the current is selectively adjusted the cooling air-flow will be adjusted accordingly. A black body 29 senses heat, light or U.V. radiation from the lamp through a translucent or transparent housing conduit 12. Its temperature increases as the radiation intensity increase and varies a bi-metallic device which moves a rod 31 leftwards. At a predetermined radiation level a cam surface 32 on the rod 31 closes contacts 34 which shorts circuits a resistor 28 thus increasing the fan speed. The contacts 34 are thereafter cycled to maintain the lamp and black body temperature within narrow predetermined limits. The rod 31 is coupled by a compression spring 36 to the link rod 28 and the spring rate of 36 is selected so that if the light output of the lamp is varied by adjusting the impedance, the datum temperature limits within which the contacts 34 are cycled will be adjusted, whereby the lamp will be maintained in a stable desired operating state. A unit 14 provides ignition pulses for the lamp and a relay 27 closes contacts 26 to switch ON the fan if the lamp fails to strike. After striking the fan is switched OFF until the predetermined temperature is reached. In an alternative embodiment Fig. 1 (not shown), the voltage drop across the arc is detected as a function of radiated power and in a further embodiment Fig. 2 (not shown), a thermistor on the conduit (4) is responsive to the radiated power.

Title: Hydrostatic transmission
IPC: B60K17/10
Filed: 1969-10-31
Abstract: 1284135 Hydrostatic transmission SUNDSTRAND CORP 31 Oct 1969 [4 Nov 1968] 53631/69 Heading F2D In an hydrostatic transmission comprising a reversible variable-displacement swashplate pump 23 and a similar irreversible motor 24 interconnected by conduits 17, 18, pressure in either conduit is limited by adjustable relief valves 140, 141 set to open at pressures dependent on the magnitude and direction of pump displacement to maintain the pressures at acceptable levels during rapid acceleration, abrupt engine-braking, and sudden load application. As shown, the pump and motor swashplates 28, 30 are adjusted by a manual lever 32 through a cam plate 62, linkages 64, 65, and follow-up servos 34, 35 including fixed pistons 39, 40, and controlled by valves 48, 49. The relief valves 140, 141 interconnect lines 17, 18, and include a sliding plug 146, 147 having a restricted orifice 151, 152 therethrough. Each valve has an associated pilot valve 169, 170 including a spring 179, 180 variably loaded by a cam 189 connected to the pump adjustment linkage. With the pump operating in forward, the spring 179 is loaded to set valve 140 to a high pressure (5000 p.s.i.) for the delivery conduit 17. When this pressure is exceeded, valve 169 opens to relieve the pressure behind plug 146, and the resulting pressure differential across the plug slides it to open the valve and interconnect conduits 17, 18. The spring 180 is unloaded to set valve 141 to a low pressure, (2000 p.s.i.). With the pump operating in reverse, the valve 140 is set to a low pressure, and valve 141 to a high pressure. Whereas the high pressure setting is constant, the low pressure setting decreases with increasing pump displacement in both forward and reverse. A shuttle valve 120 is moved by high pressure to connect the low pressure conduit 17 or 18 through a low pressure relief valve 126 to a coller 132. An engine driven gear pump 102 supplies the system through check valves 108, 109, and supplies the follow-up servos 34, 35.

Title: Method and Apparatus for Ascertaining and Controlling the Angular Deviation of Weft Threads in Moving Webs

Abstract: 1,169,778. Measuring weft alignment photoelectrically. H. MAHLO. Dec. 1, 1967 [Dec. 2, 1966], No. 54822/67. Heading G1A. [Also in Division D1] Angular deviations of weft threads in a moving fabric are detected by scanning the fabric with a photo-electric scanner and rotating the scanner in response the scanner output signal to follow the angle of the weft. The scanner ZO for the web G comprises photo-cells F1, F2 with associated slits S1, S2. The amplitude of the A. C. outputs from F1 and F2 depends upon the angle made by the weft threads and the slits S1, S2. The outputs are rectified by diodes Dl, D2 and any difference operates a polarized relay Rel whose contact K completes the circuit of a motor M to rotate the scanner ZO until the weft threads bisect the angle between slits S1 and S2. The scanner position is indicated by a meter J energized through a potentiometer MP driven by the scanner. The photocells F1 and F2 may be replaced by a single photo-cell to which light is directed from the slits S1, S2 alternately by a tilting mirror, Fig. 2 (not shown). The cell output is directed to diodes Dl, D2 in synchronism with the mirror oscillations. The mirror may be replaced by an oscillating shutter if a larger photo-cell is used, Fig. 3 (not shown). A single slit and photo-cell oscillatable between the positions S1 and S2 may be used, Fig. 4 (not shown). An oscillating system comprising an electromagnet may be provided the photo-cell signal being switched between the diodes D1 and D2 by the contact of a relay energized by a contact made by the swinging photocell arm Fig. 12 (not shown). The current through meter J may provide a control voltage for weft straightening means preferably with the addition of a control voltage from the current through relay Rel to combat time delay, Fig. 7 (not shown). In another embodiment, Fig. 5, the slit S5 and photo-cell F5 are fixed in the scanner and the motor M is energized alternately in opposite senses through contacts l3 and r3 of a relay system P, N, L, R, which changes its state at a time related to the maximum output from the photocell F5. Consequently the mean position of the oscillating scanner follows the angle of the weft threads, and this mean position is determined by the capacitor C1 from the oscillating output of potentiometer P and displayed on meter J. In another embodiment, Figs. 8-11 (not shown) light reflected from the fabric from a fixed light source is received by a pair of photo-cells on the scanner head. Reference has been directed by the Comptroller to Specification 871, 325.
