Filed: 1975-06-23
Abstract: 1511842 Hydrostatic transmission control RUBERY OWEN CONVEYANCER Ltd 23 June 1975 [27 March 1974] 13632/74 Heading F2W In a control system for a fork-lift truck hydrostatic transmission wherein a engine driven make-up pump 14 supplies pressure liquid through a pedal operated metering valve 9 and reversing valve 6 to spring centred servos 2, 3 which adjust the displacement of a reversable swash-plate pump 1 in closed circuit with a fixed displacement motor 17, the valve 9 additionally interconnects lines 15, 16 to by-pass the motor 17 when the servos 2, 3 are vented through the valve 9 for zero pump displacement. The valve 9 comprises an axially slidable valve spool 21 which, in the position shown, Fig. 5a, provides restricted communication between the make-up pump supply line 13 and the servo supply line 8. Axial movement of the valve spool 21 varies the restriction between the lines 13, 8 to adjust pump displacement. On full depression of a pedal 18 the valve spool 21 moves left to connect the servo line 8 to drain at 12 and thereafter interconnect the lines 15, 16 to by-pass the motor. A restriction 19 may be provided in the motor by-pass circuit to restrict free-wheeling of the vehicle. To prevent engine overload an additional valve spool 22 is provided in a bore in the main valve spool 21 and is moved left against the bias of a spring 26 when the pressure in the line 16 exceeds a predetermined value and connects the servo line 8 to drain through ducts 30, 31. The rate of change of pump displacement may be controlled by providing a restriction in the drain line 10 from the reversing valve 6. The reversing valve 6 may be operated by a handle 7 directly or through a cable or may be solenoid operated. A viscosity sensitive restrictor 19a in the pump supply line 13 renders the control independant of the temperature of the liquid. A switch (38) Fig. 3 (not shown) in the engine starter circuit is closed when the valve spool 21 is in its left hand position and thus only permits the engine to be started when the transmission is in neutral. A drivers seat operated switch may be provided to automatically shift the transmission to neutral when the driver leaves the vehicle. The pump displacement adjusting servos 2, 3 may be replaced by a single, double acting servo. In Fig. 7 (not shown) the lines 4, 5 to the servos 2, 3 are interconnected through a restriction which controls the rate of change of pump displacement.

Abstract: 1,043,128. Lasers. RADIO CORPORATION OF AMERICA. April 3, 1964 [April 15, 1963], No. 13918/64. Heading H3B. A laser output is amplitude modulated by applying a variable magnetic field to the solid laser active medium, which medium when excited below the laser threshold level produces a fluorescent line the width of which is not greater than the longitudinal cavity mode spacing of the laser resonant cavity. As shown in Fig. 1, the laser active medium 12 is optically pumped by a xenon flash tube and due to a homogeneous magnetic field applied by coil 20 laser action takes place between the Zeeman sublevels of two energy levels of the system. In addition to the homogeneous field a signalcontrolled inhomogeneous field is applied to the laser medium by coil 24 positioned at one end of the laser, so that the line width of the laser output is broadened, Fig. 5 (not shown). Since 'the pump power level required for laser operation is proportional to the fluorescent line width, variation in line width varies the amplitude of the output beam 22 and if the pump power is adjusted to be just above the threshold level of the laser before application of the inhomogeneous field then the laser output is switched off when the line is broadened sufficiently. In a second embodiment, Fig. 6 (not shown), coil 24 of Fig. 1 is omitted and a signal source is connected to coil 20. By varying the amplitude of the magnetic field the laser frequency is modulated in the active medium so that as the light output frequency changes the resonance conditions of the cavity determined by mirrors 16, 18 are satisfied or not satisfied and the output beam modulated in amplitude.
