Abstract: 1,092,653. Electric space heaters. PETROL INJECTION Ltd. March 24, 1965 [March 26, 1964], No. 12935/64. Heading H5H. [Also in Division F4] In a space heater in which air is drawn by a transverse flow cylinder fan 9 through an intake 6 in a casing 1 and forced over a finned tube fluid circulation heat exchanger 8 to an outlet 4, the operation of the fan is controlled by a thermostatic switching device 20, the temperature sensing element 21 of which is mounted transversely to the air intake flow path. An auxiliary heater device 24 partially surrounds or is mounted adjacent to the temperature sensing element to compensate for the cooling of the element by air drawn into the air intake 6 by the fan by supplying to the sensing element a heat input equivalent to the thermal emission from the heat exchanger when the fan is not energized. The temperature sensing element is thereby provided with an approximately constant reference temperature regardless of whether or not the fan is energized. The electrical circuit is such that the fan 9 cannot operate until both the heat exchanger 8 and the temperature sensing element 21 have reached preset temperatures, whilst the auxiliary heater device 24 cannot function until the fan 9 is in operation. The fan is located in the lower, intake part of the heater whilst the heat exchanger is located in the upper, outlet part of the heater. The intake louvres 7 and the outlet louvres 5 are uptilted and down-tilted respectively to ensure separation of the inlet and outlet air streams and to minimize turbulence at the front face of the heater. The heat exchanger 8 may be replaced by electric heating elements.

Abstract: 1, 113, 992. Measuring weight electrically. SPERRY RAND Ltd. April 1, 1965 [April 1, 1964] No. 13373/64. Heading G1N. A weighing instrument including means for compensating for the effect of acceleration comprises a first force coil 2 mounted in a magnetic field, a variable resistor 5 which controls the current in the coil so that the force produced by the coil counterbalances, at least in part, the weight to be measured, an accelerometer 6 having a second force coil 7 tending to maintain the movable element of the accelerometer in a datum position, a feedback loop 8, 9 which applies a voltage representing the sensed acceleration to the coil 7, and a circuit which applies across the variable resistor 5 a voltage which is a function of the acceleration-representing voltage. The instrument may be a continuous flow densitometer in which the liquid passes through a horizontal U-tube pivotally mounted on flexible connections and supported by the force coil 2. Movements of the object to be weighed are detected by an inductive or photo-electric pick-off 3 which delivers a signal to a servo system 4 controlling the variable resistor 5, and the voltages appearing across the resistor 5 and a fixed resistor 10 in series with the coil 7 are added by resistors 11, 12 and supplied to an amplifier 13 which provides the current to the coil 2. The circuit maintains the voltage across the resistor 5 substantially equal to the reference voltage across the resistor 10, so that the setting of the resistor 5 is proportional to the weight to be measured and is independent of the acceleration of the instrument.

[Class 108 (iii)] Relates to a shock-absorber, particularly for aircraft undercarriages of the type comprising telescoping parts enclosing a liquid and a compressible medium, such as a spring or compressed air, one of the parts consisting of a piston or plunger c, Fig. 1, having a hollow rod b containing liquid and/or a compressible medium which is adapted to be further compressed when the shock-absorber is loaded, while the other part consists of a cylinder a in which the piston or plunger c is reciprocable. According to the invention a plurality of longitudinally-extending grooves e or slots are formed in the inner surface of the cylinder to permit passage of liquid from one side of the piston to the other. As shown in Fig. 1, movement of the piston on compression of the shock-absorber is also opposed by a spring d. Apertures f in the rod b permit flow of liquid into the rod due to the decrease in the internal capacity of the cylinder on entry of the rod. The cylinder grooves e may be dispensed with and a slotted liner k inserted in the cylinder a, as shown in Fig. 2. In this case the piston c moving with an outer cylinder i is slidable in the liner k while the cylinder a is slidable in the cylinder i and is formed with a guide-plunger o having channels p providing communication between the cylinder i and an annular space o<1> below the plunger o. Liners having various kinds and arrangements of slots are shown.
