Title: A circuit for at least partial automatic control of powered vehicles by reference to speed
Inventor: DESTEK MIKLOS
IPC: B61L3/00
Filed: 1961-07-05
Abstract: 975,831. Change-speed control. GANZ-MAVAG MOZDONY - VAGON - ES GEPGYAR. July 5, 1961, No. 24329/61. Heading F2D. [Also in Division B7] In change-speed gear control for a rail or other vehicle which is operated automatically in response to output speed by polarized relays 20 . . . 24, the windings 25 . . . 29 of which are energized by an output-driven generator A and oppose windings 30 . . . 34 energized from a stabilized reference voltage source B, so that the relays change - over when the speed - responsive voltage exceeds the reference voltage, either the generator and / or relay system is duplicated and a protective circuit provided which, when one of the duplicated units is faulty, produces a fault signal or automatically switches off or selects a less dangerous circuit. The windings 25 . . . 29 are connected in series through resistors and each winding is in parallel with a further resistor, which series and parallel resistors are selected so that the relays 20 . . . 24 change-over at predetermined vehicle speeds. The response voltage of the relays is reduced to or near to the reference voltage by a unit D having a pendulum which oscillates due to the motion of the vehicle and short circuits a resistor during part of its motion thereby increasing and decreasing, within limits, the reference voltage, the frequence of alternation being less than the maximum frequency of response of the polarized relay. The control shown may control a five-speed gear driven through a friction clutch and as shown is conditioned for starting with lines 128, 129 energized which respectively partially disengage the friction clutch and engage the lowest ratio. When the output speed attains a predetermined value the relay 20 changes over and de-energizes line 128 to fully engage the friction clutch for low ratio. When a second predetermined speed is attained the relay 21 changes over to de-energize line 129 and energize a line 130 for 1-2 upshift. At further predetermined speed the relays 22 . . . 24 change over for further upshifts. Further windings 36 . . . 39 are energized from the stabilized voltage source B through variable resistors when the relay has changed over and assist the windings 25 . . . 29, thus providing a voltage difference between upshift and downshift. In Fig. 10 (not shown) two output-driven generators are provided in parallel and a relay system breaks the circuit therefrom and operates a warning light when one develops a fault. The other generator may be connected to supply the system through a manuallyoperated switch. In Figs. 11-14 (not shown) two relay systems are provided in parallel and the control system is rendered inoperative if one of the relay systems fails. The other relay system may be manually switched in to operate alone. In Fig. 15 (not shown) the relay system is provided with further windings energized by an input driven generator thus providing a control responsive to both input and output speed.

Title: Improvements in or relating to continuous cycle inert gas absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1938-08-29
Abstract: 518,730. Refrigerating. HOOVER, Ltd. Aug, 29, 1938, No. 25327. Convention date, Aug. 30, 1937. [Class 29] Absorption systems.-In a continuous-cycle inert gas system the passage of heat to one part of the evaporator is restricted to permit or increase the flow of unevaporated refrigerant therefrom to the second part of the evaporator when refrigeration is required in the second part. The first part may be for cooling a cabinet interior and the second for ice-making and the heat restriction may be imposed thermostatically. The part J of the evaporator for cooling the cabinet storage space is enclosed in an insulated casing N having openings at top and bottom closable by pivoted flaps N<1>, N<2> connected together and actuated by a rod P under the control of a thermostat Q. The other part of the evaporator is formed as looped tubes K<1>, K<2> connected by heat-conducting plates or pads M in contact with the walls of a tank L containing water to be frozen. A tnermostat S subject to the tank temperature controls the circuit of a solenoid R to actuate the rod P to close the flaps when ice-making is required, and also controls actuation of the fuel valve F<2> of the generator B, the arrangement being such that the ice-making takes precedence over the cabinet cooling, while the fuel valve is opened when either thermostat is in the "warm" position. When ice of a certain thickness has formed the thermostat S allows the flaps N<1>, N<2> to open, whereby cabinet cooling takes place, and little refrigerant flows to the ice-making part of the evaporator and the ice layers thaw off the tank walls and float to the top of the tank. Moisture condensed on the tank and evaporator collects in a tray U whence it is led away by a pipe U' and discharged over a wire insert fitted at the top of the generator flue to evaporate it into the outer air. The tank may be replenished and ice. blocks removed through a door in the top of the cabinet. In a modification the fuel valve and the rod P are actuated through pairs of solenoids acting on toggle spring switch arms.
