Title: A method of measuring, recording or regulating physical magnitudes
IPC: G05F1/12
Filed: 1936-12-28
Abstract: 487,872. Electric signalling systems. STEGHART, F. Dec. 28, 1936, No. 35540. Convention date, Dec. 28, 1935. [Class 40 (i)] [Also in Group XXXV] In measuring or recording physical magnitudes a differential mechanism is used whereof one shaft 6 is driven at a constant speed and the second 5 is driven at a speed which is equal to the sum, or the difference, of two components, one proportional to the magnitude and the other to the algebraic difference between these two speeds, and means 3 controlled by the displacement of the spider resulting from a change in the magnitude varies the speed component proportional to the algebraic differences in such a way as to maintain the equality in speed of the two shafts. This displacement from an indicated or suppressed zero is a measure of the instantaneous value of the magnitude and is employed in indicating the magnitude as by an element 10. The shaft 6 may be driven for example by clockwork or an electric motor 2 at a speed which represents the standard value of a voltage and the shaft 5 by an induction motor meter 1 the speed of which is dependent on the voltage to be measured and the member 3 operates a control device 4 so as to vary the relative excitations of differential windings controlling this speed in proportion to the difference between the speeds of the motors 1 and 2. The control device may be a variable ohmic, capacitative or inductive impedance (including a variable air gap). The inherent time lag due to the gearing enables the apparatus to be employed for protection against overload or to control a tariff meter. The invention is applicable to any physical magnitude variations in which can be translated into variations of an electrical magnitude. The time constant may be changed to suit the application by modifying the gear ratio, so that for example, readable records may be obtained with a small paper feed. The " standard value " may be varied in accordance with changes in another value, e.g. current.

Abstract: 738,970. Heat insulation. GENERAL ELECTRIC CO. Dec. 30, 1953 [Dec. 30, 1952], No. 36238/53. Class 64 (2). In making a vacuuminsulated cabinet having an inner liner 2 and outer casing 1, compressible heatinsulating material 4 which is thicker than the space between the liner and casing is placed on the outer surface of the liner and at least partially enclosed by a flexible sheath 9. The liner, insulating material and sheath are then forced into the casing, which is caused to bulge outwardly as shown. The liner and casing are temporarily sealed together at their top edges, e.g. by polyvinyl adhesive tape 12, and the space between is evacuated through the pipe 13. Atmospheric pressure causes the casing to resume its original shape. The casing and liner are then welded together at 14, and their parts above the weld are cut off. A block 11 is inserted into the liner before assembly to maintain its shape and to force it and the insulating material and sheath into the casing. A flared mouth 5 on the casing facilitates assembly. The sheath 9 may comprise metal strips or two metal sheets bent to U-shape so as to extend across the bottom and up the sides. Specification 715,174 is referred to.

IPC: G05D23/22
Filed: 1956-11-27
Abstract: 835,684. Automatic temperature control systems. GENERAL ELECTRIC CO. Ltd. Nov. 19, 1957 [Nov. 27, 1956], No. 36288/56. Class 38 (4). Temperature fluctuation in a radiantlyheated space such as an infra-red oven is reduced by an automatic control arrangement providing for two heater power levels, a higher at which the temperature tends to rise above the desired temperature, and a lower at which it falls to below it, and acting when the temperature rises above the desired temperature to switch-off the heater completely for a predetermined interval before energizing it at the lower level, thereby reducing temperature overshoot. As shown, the oven heater 1 is supplied with A.C. through two thyratrons 4 and 5 connected back-to-back, the current being controlled by a phasing network consisting of condenser 17 and resistor 23 (which is short- and opencircuited by contacts 19 and 21) operative through transformer arrangement 14 to control the phase of the grids of the thyratrons. When the oven is below the desired temperature, contacts 34 and 35 are closed and 33 and 34 open (these contacts may be controlled by an oven thermocouple by means not described) so that relay 20 is energized and the resistor 23 short-circuited; this energizes the heater 1 at the higher level. At the desired temperature 34 and 35 open and 33 and 34 close, so that 23 is open-circuited until thyratron 36 fires to close contacts 21 and bring it in circuit energizing heater 1 at the lower level; this firing is delayed by an RC network 38, 37 adjustable to provide a suitable period when the heater 1 is switched-off. Fig. 2 (not shown), illustrates a modification in which thyratrons 4 and 5 are replaced by ignitrons the firing circuit of which is closed directly by contacts corresponding to 19, and intermittently through a cycling unit by contacts 21.
