Abstract: 949,613. Thermal switches. MINNEAPOLIS - HONEYWELL REGULATOR CO. March 2, 1960 [March 3, 1959], No. 7423/60. Heading H2B. [Also in Divisions Gl and G3] A space temperature control arrangement includes an ambient temperature responsive device and a heat-radiation responsive device arranged to vary the set point of the ambient temperature responsive device. The ambient temperature bi-metal 11 is mounted on a base 10, 17 and arranged to close contacts 12 as it cools. The contacts 12 complete a circuit to control a furnace 60 and hot air fan 61 and are in series with a " heat anticipation " heater 42 adjacent the bi-metal 11. A cover 20 spaced from the base 10, 17 so as to allow air flow about the bi-metal 11 is formed with a reflector 21 which reflects radiant heat to or from an outside wall or window from or to a radiation responsive device 15. The latter comprises two bi-metals 22, 23 with the outer end of bimetal 23 secured to a housing 24 on a bracket 25 fixed on a sleeve on a post 14 secured to the base 10, 17. The inner ends of bi-metals 22, 23 are coupled by a shaft 31 and the outer end of the bi-metal 22 controls contacts 33. Changes in ambient temperature are balanced out by the opposing bi-metals 22, 23 but when the bimetal 22 gives off radiant heat to the wall or window the contacts 33 are closed to shortcircuit a heater 52 adjacent the bi-metal 11 which will consequently require a greater air temperature to open the contacts 12. When the contacts 33 close the bi-metal 22 is heated by current therethrough or by a separate heater 54 to re-open the contacts 33 so that the current to the heater 52 is " time integrated " to the heat loss by radiation of the bi-metal 22,

Title: A control system for an electric hoist motor
IPC: B66C15/00
Filed: 1948-03-18
Abstract: 656,244. Control of D.C. motors. KUKA, K. S. March 18, 1948, No. 8073. [Class 38(iii)] A hoist motor on an overhead travelling crane is controlled by means of a master switch so as to operate as a series machine for hoisting operation. Regulation of speed is effected by armature resistance variation, a resistor 12 being shunted across the motor armature to provide low speed operation on the first hoisting and lowering notches, and braking-action in the off " position of the meter switch. When an-- overhoist limit switch is operated, contacts 1L5, 4L5, open ends contacts 2LS, 3LS, close. The armature is disconnected from the line and is placed in a braking-circuit with resistor 13. During tion the motor is connected as shunt machine, acceleration being provided by releasing the armature resistance and increasing that of the field. The motor exerts a positive torque with light loads, but is driven and acts as a regenerative brake with heavy loads. A relay OSR is adapted to stop the motor and apply an electromagnetic brake in event of failure of the braking-action. This relay has coil OSR2 connectable across the armature of the motor and coil OSR3 connectable across field winding SF and brake winding SB. When there is a break in the armature circuit at a cross-bar collector CR3 the field and the brake coils remain energized and the load tends to race downwardly. A high voltage is developed across the armature of the motor and the coil OSR2 becomes effective to open contacts OSR1 and re-energize a main contactor M having contacts M1. When the limit switch is accidentally operated when lowering an overhauling load the connection of the armature in a closed loop does not prevent overspreading. The relay-coils OSR3 becomes effective, however, to stop the motor. The relay OSR is interlocked with relay 2E so that the overhoist limit switch can be re-set only when the controller is at its first lowering notch. The coil OSR3 also becomes effective if a cross-bar collector CB2 is broken or has a high contact resistance which tends to provide weak field excitation and over-speeding. A relay LLR has with LLR2 connected across resistor G and coil LLR3 across the main supply-lines, the resistor G being in shunt to the motor armature. Contacts CR1 open with time-delay after the controller has moved to its thirdlowering notch. so de-energizing the coil LLR3. the relay LLR being now held by coil LLR2. In the event of faulty operation of the limit switch during lowering operation the relay LLR drops, opens contacts LLD1, and deenergizes relay M. If there is a breakage in the resistor 13 the relay OSR may not respond to faulty limit switch operation during lowering, protection is afforded by relay LLR, however, in this case. The relay LLR also detects an earth-fault in the motor field winding or in the connection between that winding and the brake-coil. Under such circumstances the armature voltage approaches zero and the relay LLR drops. In addition, the relay LLR prevents operation of the motor unless the supply-voltage is within given limtis.

Abstract: 792,905. Hydraulic control systems; fluidactuated valves. FAIREY AVIATION CO., Ltd. March 21, 1956 [March 21, 1955], No. 8205/55. Classes 69 (2) and 135. [Also in Group XXXIII] In an hydraulic system in which a single operating member is actuated by two motors each having its own pressure supply A, B, and pressure reducing valves 21A, 21B, each valve reduces the pressure from its own supply by approximately one-half but will supply full pressure if the other supply fails. The system, as applied to an aircraft control surface 10 operated by a tandem hydraulic jack unit 11 comprises tanks 15A, 15B, pumps 16A, 16B, accumulators 19A, 19B, the reducing valves 21A, 21B, and non-return valves and filters. Each accumulator is connected to both valves 21A, 21B. Each reducing valve (Fig. 2) comprises a piston 53 movable in a liner 42 in a casing 40. The casing (and liner) have an inlet 47 and an outlet 48 and a drainage connection 49. The piston is moved to the left by a spring 54 and as the fluid pressure increases the fluid exerts a pressure in a chamber 56, via channels 61, 55, and moves the piston 53 against the spring 54, partly closing the inlet 47 until an equilibrium position is reached. The supply B is connected to a port 51 and acts on a piston 71 against the pressure of supply A which is connected to a port 50. If the supply B fails, a plunger 73 moves the piston 71 and a piston-rod 75 thereon engages and moves the piston 53 opening fully the inlet 47 and full pressure is supplied via system A.
