Title: Improvements in weighing scales
IPC: G01G19/44
Filed: 1928-10-26
Abstract: 321,056. Marks, Sir G. C., (Toledo Scale Co.). Oct. 26, 1928. Pendulum-weight apparatus.-In a personal weighing machine, a weighing platform overlies a base housing associated with an upright housing provided with an indicator window which is located at approximately three feet above the level of the platform and is of small dimensions such that it exposes only a portion of a revoluble chart mounted within the upright housing and co-operating with a stationary index to indicate the weight on the platform, the weight indications being only visible to the person standing on the platform. The platform 27 rests upon knifeedges carried by a platform lever and is secured to an upwardly-extending arm 60 steadied by a check link 61. The platform lever is coupled by a link 31, lever 32 flexible ribbon 34, and power sector 35 to a pendulum 36 supported by fulcrum sectors 37 which are suspended by flexible ribbons for rolling movement upon guiding faces 39. A rack bar 46 pivotally connected to the axis of the fulcrum sectors actuates a revoluble indicating chart 52 situated about three feet above the platform and viewed through a window 54. A lamp 55 illuminates the chart each time the pendulum moves from its zero position. The initial balance of the parts is obtained by means of a loading box on the platform lever and by adjusting the pendulum weight 41 on its supporting arm. An adjustable balance weight 42 is also provided on the lever 32. Vibration, neutralizing. - A dash-pot 64 mounted on a shelf 65 is connected to the lever 32 to damp vibration.

Title: Improvements in or relating to time control circuits employing transistors
IPC: H03K17/28
Filed: 1958-10-01
Abstract: 863,144. Transistor circuits. SQUARE D CO. Oct. 1, 1958 [Oct. 25, 1957], No. 31331/58. Class 40(6) [Also in Group XXXV] In a time control circuit, upon operation of an initiating switch a capacitor which had previously been charged through two electrodes of a transistor, and a source of voltage discharges and then commences to charge from the source, the charging continuing until the transistor conducts to its third electrode and so terminates the timing period. In the quiescent state of the circuit shown, a capacitor 36 is charged due to a circuit from a battery 10 through the base-emitter paths of transistors 20 and 30. Upon operation of a control switch 15 a relay 18 operates and its contact 47 causes a relay 44 to operate. One contact 43 of this relay connects a power supply 40 to a load 42 while a further contact 16 provides a holding circuit for relay 44. Capacitor 36 now discharges through a circuit comprising resistors 37 and 38, a relay contact 25 which was made when relay 18 operated, the battery 10 and contact 16. The voltage across capacitor 36 accordingly decreases to zero and then increases to a value at which transistor 30 conducts. This renders a further transistor 20 conducting causing a relay 21 to operate. Contact 48 of this relay interrupts the circuit of relay 44 causing the circuit to restore to its initial condition. A diode 23 prevents reverse current flow through the transistors and resistor 38 permits the time during which relay 8 is operated to be varied. Transistor 20 may be omitted, in which case relay 21 replaces resistor 32. If relay 18 is less sensitive than relay 21 then providing battery 10 has sufficient power to operate relay 18, relay 21 will also operate so that the circuit "fails safe" in this repect.

Title: Improvements in or relating to magnetic cores for electric transformers or the like
IPC: H01F41/02
Filed: 1952-12-11
Abstract: 728,403. Transformers and inductances. WESTER, H., and WESTER, T., [trading as WESTERWERKE FABRIKEN HOCHFEUERFESTER ERZEUGNISSE]. Dec. 11, 1952, No. 31456/52. Drawings to Specification. Class 38 (2). In order to improve the magnetic properties of magnetic cores for transformers or the like, the core is subjected to two oscillating magnetic fields, one circular and the other longitudinal, and to a mechanical stress, the two magnetic fields being of the same frequency but relatively phase displaced and the mechanical stress produced by giving the core a specific angle of twist, thereby producing a core having a single line magnetization characteristic. The core may be twisted so that its coercivity and remanence become negative and then annealed and given that the phase displacement between the two magnetic fields is 90 degrees, the resulting magnetization curve of the core will be rectilinear. The circular oscillating magnetic field is produced by passing alternating current through the core whilst the longitudinal oscillating magnetic field is produced by passing alternating current through a coil wound around the core. Angles other than 90 degrees between the magnetic fields give a magnetization curve which is a single line but not rectilinear.

Abstract: 781,141. Photographic colour processes. PETREN, T. S. A. Nov. 9. 1955 [Nov. 12, 1954], No. 32009/55. Class 98(2) A photographic colour print is made by impregnating a paper or cardboard base with a cellulose derivative or synthetic resin which is soluble in a volatile organic solvent, coating the base with a lightsensitive bichromate emulsion, exposing to a screened picture developing to remove the unexposed portions, dyeing the uncovered base with a dye in a solvent for the cellulose derivative or synthetic resin and removing the remaining bichromate emulsion. Multicolour prints are obtained by exposing in turn to screened separation diapositives and dyeing with the appropriate primary dye, the base being recoated with bichromate emulsion. and the process repeated for each separation positive. The base may be impregnated with nitrocellulose or cellulose acetate. Thus the base may be first impregnated with a varnish of nitrocellulose in butyl acetate, ether and alcohol as solvents and diluted with acetone, ethyl acetate or butyl acetate, and then. impregnated a second time with the undiluted varnish and dried. The impregnated base may then be coated with gum arabic and ammonium bichromate, and after exposure the unexposed parts are washed away. The dye solution may cantain acetone, ethyl acetate or butyl acetate but its solvent activity is preferably limited by adding a solvent which will not attack the base such as ethyl alcohol, which may also act as solvent for the dyes (e.g. aniline dyes). Water or an aqueous solution of glyoxal also may be added to the dye solution, and the latter may contain ethyl cellulose or other cellulose derivative or synthetic resin. After dyeing the remaining emulsion is washed off with water.
