Title: Alternating current apparatus for measuring capacitance or comparing voltages
Inventor: KUSTERS NORBERT LEO
IPC: G01R27/26
Filed: 1970-03-12
Abstract: 1,254,827. Measuring currents. CANADIAN PATENTS & DEVELOPMENT Ltd. March 12, 1970 [April 24, 1969], No. 11988/70. Heading G1U. Apparatus for comparing two currents in magnitude and phase, e.g. the currents through capacitors C x , C s  respectively, comprises a closed magnetic core 10 which carries two current windings 15, 16 and a detection winding 11, the winding 16 carrying one of the currents to be compared, the winding 15 forming part of an adjustable network connected to the source of the second current, and the winding 11 being connected to a null detector D for sensing when the net flux in core 10 is zero. The current windings 15, 16 are the outermost windings on core 10 and are shielded from the detection winding 10 and a compensating winding 14a by an interposed magnetic shield M2. It is stated that the compensating winding draws very little current and thus maintains at a low value the potential across that portion of the network which is in series with the source of the second current (i.e. the potential between P<SP>1</SP> and earth). Current windings 15 and 16 are said to act as a current transformer having an effective burden of variable resistor R<SP>1</SP> and capacitor C1 in parallel. The latter are not connected directly in parallel with each other, but the voltages across them are maintained equal and of either the same or opposite sign, according to the sign of the phase difference between the two currents to be compared, by switch SW and either an autotransformer T3<SP>1</SP>, Fig. 3, or an ordinary transformer (T4), Fig. 7 (not shown) with an earthed centre tap on its secondary. The flux in core 10 is reduced to zero by adjusting the taps on windings 15, 14a for in-phase components and resistor R<SP>1</SP> for quadrature components. A finer degree of in-phase adjustment may be provided by connecting a variable conductance between terminal 2 in Fig. 3 and earth. The circuit may be modified Fig. 5 (not shown) to allow the variable resistor R<SP>1</SP> to be connected between winding 15 and earth. Applications (i) To determine the capacitance and dissipation factor of a h. v. capacitor C x  by comparison with a standard capacitor C s , an A. C. supply V is connected across both capacitors and the currents through them compared. (ii) To test a transformer T5, Fig. 9, the primary and secondary voltages V p , V s  are applied across respective standard capacitors C a , C b , the currents through which are then compared in magnitude and phase.

Filed: 1972-03-15
Abstract: 1378532 Illuminating instrument dials W S STONE 15 March 1972 [18 March 1971] 12015/72 Heading G1J [Also in Divisions F4 and G3] For illuminating the dial of an alarm clock or meter, for example, a transparent cover 16 for mounting over the dial has a lamp 50, one or more batteries 30, 32, 34 and a switch 60 either mounted directly thereon or an a mounting element itself supported by the cover 16. As shown, these components are mounted on the inside of the acrylic or lucite cover 16, which itself is a removable snap fit with the dial casing. The tip of switch button 64 extends through an aperture 66 in the cover 16 and carries phosphorescent material 63, and a disc 62 engages resilient contact 58 which upon operation of the switch co-operates with stationary contact 56 to complete the lamp circuit. The components may be cemented to the cover 16 or, when supported on a mounting element, Figs. 6-8 (not shown), may be removably secured to the cover 16 by screws. The cover assembly may form a complete unit which is discarded and replaced when the battery has run down.

Abstract: 525,249. Drying and cleaning air filters &c. MANN, EGERTON & CO., Ltd., and WILFORD, G. L. April 21, 1939, No. 12043. [Class 138 (i)] [Also in Group II] An apparatus for drying, or drying and cleaning, air filters for internal combustion engines, comprises a container 1 fitted with a cross bar 7 on which is rotatably mounted a hollow turntable 8 having an apertured wall and provided with external vanes 9 on which compressed air from a nozzle 10 is adapted to impinge to drive the turntable and so to cause any cleaning liquid on an air filter disposed in an inverted position in the turntable to be thrown out. The air filter is held in place by a clamping bar 14 mounted on spring-surrounded screw rods 12. The turntable is clamped to a flanged sleeve 21, Fig. 2, rotatable in ball bearings 22, and the lower end of this sleeve registers with a shroud 24 of a nozzle 25 connected by a pipe 25a to the supply pipe 27, Fig. 1, of the compressed air, the control of which to the nozzles 10, 25 is regulated respectively from taps 10b, 26. The container 1 has a supply of paraffin sufficient to cover the shroud 24. In use, with the clamping bar 14 removed, the turntable stationary, and the air filter inverted from its drying position, the tap 10b is closed and the tap 26 opened, so that the interior of the filter is washed by a spray of paraffin. After cleaning, the tap 26 is turned off, the filter inverted and clamped in the turntable by the clamping bar 14, and the tap 10b is then opened for the supply of compressed air to the nozzle 10. The container may be provided with a gauze filter above the level of the paraffin.

Title: Improvements in or relating to the manufacture of assimilable preparations containing calcium compounds
IPC: A61K33/06
Filed: 1936-04-28
Abstract: A double compound of calcium oxychloride and asparagine is prepared by adding the oxychloride to a solution of asparagine in hot water. Similarly, compounds of calcium chloride with urea, and of calcium lactate with quinine, may be prepared.ALSO:Assimilable calcium-containing preparations having only a slight calcereous taste are obtained by mixing at least two per cent of a soluble organic compound of calcium with a liquid which does not combine therewith to form crystal aggregates and is such that the proportion of the electric conductivity of the preparation due to calcium ions is very much less than the conductivity of an equivalent solution of the calcium compound dissolved in water, on account of low electrolytic dissociation or low ionic mobility or both.  The liquid should preferably be viscous and contain less than 30 per cent of free water.  Examples of suitable liquids are: iso-stable lyophylic colloids such as glucose syrup, kitchen syrup and dextrin solution, and emulsions of oil in water or water in oil.  The calcium compound used may be calcium lactate, calcium sodium lactate, calcium gluconate, or double compounds formed between calcium compounds and organic nitrogen-containing substances, for instance, calcium chloride-urea, calcium lactate-quinone, or calcium oxychloride - asparagine.  Each double compounds may be added as such or may be formed in situ by adding the separate ingredients.  The taste of the preparations may be further reduced by addition of other electrolytes.  According to an example, a mayonnaise may contain groundnut oil or olive oil, vinegar, egg yolk, calcium lactate and water, with or without a colloid such as gelatine.  Mixtures of calcium compounds with gelatine solution alone, or with saccharose solution alone are stated to be unsuitable.

Abstract: 347,869. Resistance measurements. FAULTRIER, G. DE, 27, Rue Danton, Lyons, France. April 22, 1930, No. 12481. [Class 37.] A resistance to be measured is placed across terminals m, n in series with a neon or other lamp f and a source of current, a known variable resistance c being arranged in series with a similar lamp d and the same current source. The resistance c is adjusted until the currents passing through the lamps d, f are equal, as indicated by equality in the luminosity of the lamps. The value of the resistance to be measured is then equal to the known value of the resistance c. As shown the source of current is a Ruhmkorff coil u, the secondary winding of which has a small airgap of about half a millimetre in series with it between terminals b, b<1>, and is shunted by a condenser l having a capacity of one or more microfarads. In order to enable the luminosity of the lamps d, f to be compared, they are arranged side by side separated by a thin partition o, Fig. 2, and are observed through an unpolished glass r.
