Abstract: 630,953. Refrigerators. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 4, 1948, No. 6759. Convention date, March 12, 1947. [Class 29] A refrigerator door comprises an outer panel 10 having an inwardly-extending flange 12 to which is rigidly secured a frame 14 on which the inner panel 38 is slidably secured by slidable clip members 28 and a resilient gasket 42 to allow the inner panel to expand or contract under varying temperature and humidity conditions. The space between the panels is filled with insulating material 56. The rectangular frame 14 is welded at its outer edge td the flange 12 and the inner panel, which may be of fibrous material impregnated with a phenolic condensation resin, has its edge portions lying adjacent to the body portion 16 of the frame and held in place by inwardly-turned projections 34 of the elongated clip 28. Tabs 30 struck up from the clip 28 pass through holes 24 in the frame and engage the under side of the frame 14. The holes 24 are large enough to permit the clip 28 to be slid towards the adjacent edge of the door so that the projections 34 release the inner panel 38. To hold the clip in securing position a rubber locking strip 42 is inserted between projections 36 on the clip and the flange 12, grooves in the locking strip gripping the projections 36 and a projecting portion of the flange 12. A balloon gasket 48 integral with the locking strip forms the seal for the door. The slidable clips 28 may extend along all four edges of the door or along the two edges only, the inner panel and the gasket being secured along the other two edges by clips welded to the frame 14. Specification 536,817 is referred to.

The temperature of the further body is controlled by a heater (not shown) until "radiation equilibrium" and thus temperature equilibrium has been reached. At this point a measurement of the temperature of the body under test is provided by a contact thermometer (not shown) on the further body 1 or 1'. The infrared detector's A.C. output may be phasesensitive rectified and its output used to control the heater until the amplitude of the A.C. signal decreases to zero when the temperature equilibrium has been reached.

Title: Aircraft control system
IPC: G05D1/06
Filed: 1962-02-21
Abstract: 984,585. Automatic control of aircraft. BENDIX CORPORATION. Feb. 21,1962 [March 6, 1961], No. 6787/62. Heading G3R. In an aircraft automatic pilot, signals from a heading or pitch attitude gyro and a radio beam receiver combine to steer the aircraft and electrical means responsive to persistent components of the gyro signals are effective to remove such signals from control. In Fig. 1 manual operation of a switch 34 energizes a relay 30 for normal flight so that signals from the pick-off 15 of a gyro-magnetic compass 11 are applied through an inductive device 19, set to a desired heading, a demodulator 41 and a modulator 42 to an A.C. amplifier 43. The output of amplifier 43 is applied, together with signals from a roll gyro pick-off 13, a turn potentiometer 44, and a roll trim potentiometer 45, through a demodulator 51, modulator 52, amplifier 54 and power demodulator 55 to control clutches 56, 57 associated with a servomotor 58 so that ailerons 59 are actuated to maintain the desired heading. Signals from a tachometer generator 53 driven by servomotor 58 are integrated at 50 and applied as follow-up signals to modulator 52. To capture an omni-range or localizer radio beam, manual operation of a switch 35 energizes a relay 31 and releases relay 30 so that the signals from gyro-compass 11 are applied through an inductive device 26, set to correspond with the beam heading, and demodulator 41, to control the aileron servo-system. Energization of relay 31 also applies signals from a radio beam receiver 10 through a modulator 65 and an amplifier 66 to amplifier 43 so that the aircraft is steered into the beam by means of the airlerons. Later, to track the beam, manual operation of a switch 36 energizes relays 32, 33 and releases relay 31 so that although the signals from the radio receiver and gyro still combine to control the ailerons the former are attenuated by operation of contact 80, and a condenser 63 is inserted by operation of contact 61 so that persistent signals from the gyro, e.g. due to the effect of cross-wind, are opposed by the charging of a condenser 63. A glide-path control system is also described with reference to Fig. 3 (not shown) in which modulators and demodulators employ transistors. In this arrangement elevators and elevator trim tabs are controlled by signals from the pick-off of a pitch gyro during normal flight, and additionally through two channels by signals from a glide-path radio receiver when the latter is switched in. When necessary, e.g. when the aircraft approaches the glide-path from below and the radio signals conflict with the gyro signals, a condenser is introduced into the gyro signal circuit to eliminate persistent signals in the manner of condenser 63. Specification 984, 584 is referred to.

IPC: B60Q11/00
Filed: 1922-03-08
Abstract: 190,100. Renault, L. Dec. 8, 1921, [Convention date]. Lighting systems for vehicles comprise a main source of current adapted to supply the main lamps, an auxiliary source of current and a switch adapted to control the lamp circuits in such a manner that the condition of the auxiliary circuit is ascertained before the main circuit is closed. The main source of current consists of a generator 1 or a battery 2 adapted to be connected to the main lamps 3 through a switch 4 and the winding 7 of a magnet 8. The auxiliary source of current 6 is adapted to be connected to the .auxiliary lamp 5 through the switch 4 and the contacts 13 of an electromagnetic switch when the main circuit fails. To switch on the lamps the handle 9, carrying the contacts c, c<1>, of the switch 4 is moved to bridge the contacts a, a<1> thereby connecting the battery 6 to the lamp 5. A further movement of the handle 9 connects the contacts b, b<1> thereby connecting the source 1 to the lamps 3. The closure of this circuit breaks the circuit of the auxiliary lamp 5 at the contacts 13 but this circuit is again established if the main circuit fails.
