Filed: 1962-03-21
Abstract: 1,030,161. Photoconductive cells. HILGER & WATTS Ltd. March 20, 1963 [March 21, 1962], No. 10840/62. Heading H1K. [Also in Division G1] The position of a transverse boundary 20 of an area of light 18 is determined by the use of a photo-conductive cell comprising a longitudinal band 12 of high resistance material and parallel bands 4 and 6 of low resistance material separated by and in electrical contact with regions 2 of photo-conductive material. The bands are connected in parallel at one end of the cell and brought to terminal 16, whilst the other end of the band 12 is brought to terminal 14, via conductive band 10. The two terminals are connected to a resistance measuring device. As the light area 18 sweeps across the photo-conductive material 2 the resistance of the said material drops to nearly zero, short-circuiting the length of the resistive band 12 covered by the light area. The resistance measured at terminals 14 and 16 therefore represents the position of boundary 20. The photo-conductive material may be cadmium sulphide, the resistive band 12 may be a nickel-chromium alloy and the conductive bands 4 and 6 may be of gold. The resistance measuring device may be a voltmeter in series with a constant current supply.

Abstract: 1,262,664. Measuring length electrically; measuring magnetic field strength. G. ALICH. Feb. 28, 1969, No. 10923/69. Heading G1N. The distance between two ferromagnetic rolls 1, 4 Fig. 2 is determined by producing a magnetic flux 11 in the space between the rolls, whose intensity is measured by magnetic resistive semiconductor elements 10<SP>1</SP>, 10<SP>11</SP> , and is indicative of the length of the space. The flux 11 is produced by an energized winding 9 on a core assembly 8 in contact with the rolls 1, 4 via poles 8<SP>1</SP> , 8<SP>11</SP>. The resistance of the elements 10<SP>1</SP> , 10<SP>11</SP> is compared in a bridge circuit 13 with that of two similar elements 12<SP>1</SP>, 12<SP>11</SP> located in the field produced by a winding 16 whose energizing current via is adjusted to balance the bridge. The probes 10<SP>1</SP> , 10<SP>11</SP> are located symmetrically with respect to the axial plane of the rolls 1, 4 so that small lateral displacements produce differential effects on their resistances and are thus automatically compensated. The probes 10<SP>1</SP>, 10<SP>11</SP> are mounted on a carrier 17 Fig. 5 with spring fork arms embracing the two rolls to make the carrier and the probes follow lateral displacements of the rolls relative to each other. The carrier 17 may incorporate a temperature sensitive resistor to compare the temperature with that of the other magnetic core 15. In another embodiment Fig. 9, the thickness of a non-magnetic wire or tape P is measured by its effect on the flux density in the gap between poles 34<SP>1</SP>, 35, as sensed by the probe 10, and compared with the flux density sensed by probe 12 in a similar arrangement with a standardized gap. The exciting windings for the two magnetic circuits are connected in series.

Abstract: 1,081,664. Centre-post gramophone recordchangers. V-M CORPORATION. March 14, 1966, No. 11122/66. Heading G5R. A record stack is supported on fingers 40 which project through slots 34 in a stationary spindle body 26, the lower edges 88 of slots 34 being disposed beneath turn-table recordsupporting surface 32. When it is desired to lower the bottom record of the stack a rod 50 is raised to cause cam-controlled gripping pads 48 to engage all but the lowest record. This record is then lowered by fingers 40 until it almost reaches support surface 32, the fingers 40 being retracted within spindle body 26 when they engage the lower edge 88 of slots 34 or the centre holes of records already on the turntable. Fingers 40 are mounted on a rotatable sleeve 36 provided with a cross-pin 66 which engages cam tracks 80, Fig. 9, in a stationary cam 78 and cam tracks 70 in a rotatable cam 68 which is rotated by reciprocating rack means (not shown) acting on pinion teeth 72, Fig. 1. To lower fingers 40 cam 68 is rotated to the left, Fig. 9. When pin 66 reaches the bottom of portion 81 of cam track 80 the rotation of cam 68 is reversed so that surface 76 of cam track 70 causes pin 66 and sleeve 36 to rotate approximately 30 degrees thus moving fingers 40 out of alignment with slots 34. Continued rotation of cam 68 causes sleeve 36 and fingers 40 to rise inside spindle body 26 until pin 66 on reaching portion 86 of cam track 80 causes fingers 40 to become aligned with slots 34 through which they will project to support the stack of records which are then released from gripping pads 48.

Title: Process for purifying trifluorochlorethylene
IPC: C07C17/38
Filed: 1957-04-08
Abstract: Trifluorochlorethylene, contaminated with oxygen, is treated in the gaseous state with a liquid capable of absorbing oxygen. Suitable liquids are alkaline pyrogallol solution, alkaline hydroquinone solution or preferably an alkaline solution of sodium dithionite. After freeing from oxygen the trifluorochlorethylene may be dried for example with calcium sulphate, calcium chloride, phosphorus pentoxide, sulphuric acid, or silica gel.  If crude trifluorochlorethylene is used as starting material it should preferably be distilled after drying. The process of the invention should preferably be carried out immediately after the C2F3Cl has been prepared or purified, i.e. before it has come into contact in the liquid state with oxygen, suitable temperatures are between 10 DEG  and 30 DEG C.  The C2F3Cl obtained by the process of the invention remains stable for some time.  An example is given of the stabilisation of trifluorochlorethylene which has been prepared from 1,1,2-trifluoro-1,2,2-trichloroethane by treatment with zinc dust in methanol.  The crude gaseous product is passed through an alkaline solution of sodium dithionite and then dried by passing it through concentrated sulphuric acid.  The C2F3Cl is then purified by close fractionation.
