Title: Improved refrigerator
IPC: B28B21/40
Filed: 1957-12-19
Abstract: 815,460. Refrigerators. GENERAL MOTORS CORPORATION. Dec. 19, 1957 [Jan. 8, 1957], No. 39460/57. Class 29 A refrigerator has food storage and freezer compartments 24, 60 and associated evaporators 32, 64 situated outside the compartments in separate forced air circuits. Blower 42 draws air from the storage compartment and forces it over the evaporator 32 and the sensing element 125 of a thermostat controlling the compressor motor. Melt water leaves the compartment through orifice 46 and is led to a tray 54 in the machine compartment. A small heater 56 keeps the orifice 46 free of ice. The freezing evaporator rests on the liner 62 and is in contact with the false floor 66 of the compartment. Air is drawn through the evaporator by blower 70 and flows through a duct at the back of the freezing compartment where it is slightly warmed to lower the relative humidity before entering the compartment through orifices 80. The air leaves the compartment through orifices 90 communicating with a passage 92 leading to the evaporator. A heater 129 controlled by a time switch is secured to the freezer evaporator 64 for defrosting. Preferably the compartments have separate doors and the blowers may be caused to switch off when a door is opened. Operation of the blowers may be dependent on the operation of the compressor. Specification 796,626 is referred to.

Filed: 1969-08-11
Abstract: 1282166 Hoist brakes INGERSOLL-RAND CO 11 Aug 1969 40109/69 Heading B8B [Also in Division F2] A pneumatic load balancing hoist housing a cable drum 7 mounted through a ball nut and screw 4, 6 within a casing 1, 2, 3, includes a brake responsive to a load on the hoist cable 14 and operative to hold the drum against rotation in a direction to raise the cable unless a load thereon is secured. The hoist is supported by plates 21, 22 of a trolley through a load sensing arrangement which operates a pair of drum brake shoes through a cam and linkage arrangement in response to the cable load. The drum is caused to be braked only when a regulated pneumatic pressure is applied to a chamber 28 in communication with a pressure chamber in the load sensing arrangement, to rotate the drum and there is no load on the cable 14, this causing a displacement of the hoist casing 1, 2, 3 relative to the plates 21, 22 to operate the brake linkage. In another embodiment, Figs. 6, 7, 8 (not shown), the drum braking is effected by a pawl operated through the said cam and linkage arrangement for engagement with ratchet teeth formed on the inside of the cable drum.

Abstract: 935,752. Magnetic recording &c. apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 10, 1959 [Dec. 13, 1958], No. 40243/58. Class 40 (2). [Also in Group XXXIX] A time delay is produced by having spaced record and playback heads 4 and 5 on a moving record medium 1 the time delay being variable by varying the spacing between the heads 4 and 5 and by varying the speed of the record medium. A coarse control of the time delay is made by selecting one or other of a number of playback heads 5 by means of a switch arm 6 controlled by a solenoid 7. Fine control is made by varying the speed of the record medium as by using a capstan roller 2 driven by an electric motor 9 the speed of which is governed by an input voltage at 10 applied to the motor by way of an amplifier 11. To maintain constant the pitch of the output signals as the speed of the record is varied, the signals may be recorded as phase or pulse-modulations. The tape may be a closed loop and be provided with an erase head. Recording may be made on a rotating disc or drum. More than one recording track may be employed.

Abstract: 1440855 Controlling lateral canting HONEYWELL Inc 26 Sept 1974 [28 Sept 1973] 41850/74 Heading B7D [Also in Division E1] In an earth working machine, control of the position of frame 11 relative to wheels 12 is effected by hydraulic rams or screw jacks 17-20 and a system comprising a sensor 21, e.g. a gravity operated pendulum sensor, for providing an output dependent on the deviation from the preset value of the slope of the frame at one end and a sensor 30 for providing an output dependent on the difference in slopes between opposite ends of the frame. An amplifier, having an input from a preset potentiometer and an input from the sensor 21, provides an output which is proportional to the deviation between the actual slope sensed by the sensor 21 and the reference as established by the potentiometer. The proportional output from the amplifier controls a servo valve or motor 22 of the ram or jack 18. A bar 27, rigidly fixed at one end to the frame and supported at its other end by a bar 28 and bearings 29, rotates relative to the left hand side of the frame, as viewed in Fig. 1, when the slope across the front of the frame differs from that across the rear of the frame. A porportional output from an amplifier connected to a feeler 32 and the sensor 30 is used to control a servo valve or motor 31 connected to the ram or jack 17. The bar 27 may be mounted from the front to the back of the frame. The elevation of the machine is controlled by feelers 34a, 35a of sensors 34, 35 engaging a wire 33.
