Title: Improvements in or relating to electronic alternating-current energy meters employing hall generators
IPC: G01R21/08
Filed: 1963-10-23
Abstract: 1,012,464. Selective signalling. SIEMENS-SCHUCKERTWERKE A.G. Oct. 23, 1963 [Oct. 31, 1962], No. 41923/63. Heading G4H. [Also in Divisions G1 and H3] In an electronic A.C. energy meter, a first A.C. signal is rectified and used to energize one input of a Hall generator, to the other input of which is fed a second A.C. signal and from the output of which is derived a Hall voltage which is a product of the rectified first signal and the second signal. This Hall voltage is supplied to an A.C. amplifier and thereafter to a switching arrangement for producing a third signal by reversing the polarity of alternate half cycles of the amplified Hall voltage, the third signal being fed to an integrating device. In an embodiment (Fig. 2) a signal related to a voltage U is rectified at 5 and passed to the field winding 7 of a Hall generator 4. An alternating current signal through the load 3 is passed to the Hall element 4 and an A.C. output signal U H  is taken from the element and supplied to the amplifier 8, only the output circuit of which, including the windings 9 and 10, is shown. These centre tapped windings 9, 10 supply diodes 11, 13 and 12, 14 respectively so that alternate half cycles of the amplified Hall voltage will be reversed. In addition, the output circuit is controlled by a binary circuit 18 through the transformer 17 so that the polarity of the rectified output U z  applied to the choke 19 may be reversed, in accordance with the setting of the binary circuit. The choke 19 is an integrating choke which saturates after a given amount of energy has been supplied to it, and the purpose of the binary circuit reversing arrangement is to reverse the direction in which signals are applied to the choke as soon as it saturates. To achieve this a relaxation amplifier is energized from the signal across the resistor 20 which signal becomes large as soon as the choke saturates. The relaxation amplifier delivers a signal which changes the state of conduction of a transistor-diode arrangement 26, thus delivering an impulse to change the state of the binary arrangement 18. The signals derived by the relaxation amplifier 21 are also fed to switching transistors 22 and thence to a counter 23 which indicates the energy supplied. An alternative arrangement (Fig. 4), designed to eliminate the bi-stable arrangement 18, utilizes a split choke 19 and the signals derived from the relaxation amplifier 21 are used to operate switching circuits which complete a signal path through one or other sides of the choke. The amplifier 8 is described in detail (see Division H3).

A carrier strap 20 passes round the user's neck, through the strap guides 22 on couplings 16 and fixes to pegs 23 on the flat cylindrical blower housing 29 constructed of two shells. Projections 28 support the nozzle 17 to which electric heating elements 26, fan motor 25 and fan 24 are attached. The lower portions of flexible walls 18 within hoses 15 are air-tightly joined on the user's neck sides to hose walls 19, with their ends being free and acting as valves to permit the supply of heated air to the hood but prevent air flowing out from the hood. The extension pieces may converge to form a common air inlet 30 in the embodiment of Fig. 5, which inlet connects with the blower air outlet nozzle 31 by an elastic ring 32 thereon mating with a nozzle shoulder 34. The nozzle 31 may be oval and the shoulder 34 provided only at the regions of greatest curvature, tear-resistant lugs 35 on the inlet 30 also being provided in these regions. The carrier strap 20 slides through coupling pieces 36 with coupling heads 37 which lock with a rotary action into elongated holes 38 in the housing 29.

The position of a shaft is controlled by supplying pulses, corresponding in number to the desired position, to a ring counter Z 1 -Z n  and comparing the desired position with the present position stored in one of bi-stable stages S 1 -S n  to determine the shortest route to the new position. After entering the new position in the ring counter, n pulses are supplied on input 1 to cycle the counter, and while this is taking place, a bistable device B is triggered to operate a twoposition switch W when the active stage of the ring counter is transferred from Zn to Z 1 , and also one of coincidence gates K 1 -K n  provides a pulse on L1 when the momentarily active stage of the ring counter corresponds to the active stage in store S 1 -S n . The coincidence pulse passes to either output I or output II depending on whether or not device B has been previously triggered. The coincidence pulse is also used to reset stages S 1 -S n , and some time later the desired position is transferred from Z 1 -Z n  to S 1 -S n  through gates T 1 -T n  in order to effect the re-positioning of the shaft.

Valves 26 and 27 in the pipe 18 which are operated by the clutch 8 and the gear-box 6, respectively are open when the clutch is engaged and the gear-box is in gear. A single valve (5), Fig. 2 (not shown), in the pipe 18 may be opened when an automatic transmission is operative by means of a mechanical connection (3) or an hydraulic connection (2). The by-pass valve may comprise a diaphragm 38 biased by a pair of springs 46 and 47 of different rates against the vacuum applied through the passage 18. The lighter spring 46 acts during movement of the valve member 39 to open a first restricted by-pass 43 and the heavier spring (47) acts during opening of an additional by-pass (40a). In a further embodiment of the by-pass valve, Fig. 8 (not shown), the springs (46, 47) are mounted on the same side of the diaphragm as the valve member (39).

Abstract: 1,094,865. Resistors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 20, 1965 [Nov. 27, 1964], No. 44416/65. Heading H1S. To form (meandering) resistor elements from a cermet film 14 (Fig. 1), the film includes a sufficiently large proportion of metal (70%) to be attackable by a suitable etching solvent removal of the metal leaving behind a dielectric remnant which can be easily removed as by washing. To secure adhesion of a copper conductor film to the cermet an under layer 16a of aluminium, chromium/copper or aluminium copper/alloy is deposited so that, like the copper film 16b, it can be etched away by an etchant (ferric chloride solution) which does not attack the chromium in the cermet. The cermet film 14 is flash evaporated in a vacuum which if of Cr-SiO 2  must contain at least 70 atomic per cent of Cr on to an SiO substrate 12 on a heat-resistant glass base 10. The resistance of the cermet film is determined by monitoring the resistance of a separate slide and stopping deposition at the required value. Simultaneous evaporation of Cr and Cu produces the alloy under layer 16a and continuing evaporation of Cu, the layer 16b both of which are etched using photo-resist 18 to form the desired conductor patterns (Fig. 3, not shown). The cermet film is then etched to form separate (meandering) resistance elements by AlCl 3  using a further photo-resist and after cleaning is covered by a SiO film. The resistor panel so formed is cleaned ultrasonically and annealed in argon-hydrogen at 400-450 C. for a time determined by monitoring the value of one of the resistors. The value of individual resistors may subsequently be adjusted by local heating. The cermet film may be made using 90 at per cent Cr-10 mol. per cent SiO dissolved in a solution consisting of 1 lb. AlCl 3 .6H 2 O, 135g. ZnCl 2 , 30 ml. H 3 PO 4  and 400 ml. water. The film is depassivated before etching by contacting its surface with zinc pellets or powder.
