A hand tool for use in straightening wires or cables comprises two housings A, B of generally U-shaped cross-section, each carrying rollers C, D, respectively, rotatable about axes transverse to the length of the housing, means for latching the two housings in an operative position with their open sides facing one another, spring means J acting in such operative position to urge the two housings towards one another to enable the two sets of rollers to grip between them a wire or cable passing longitudinally between the two housings, and means whereby on release of the latching means the two housings can be moved relatively about a hinge axis parallel to the lengths of the housings to facilitate insertion and withdrawal of the wire or cable. Pivot pins E, E<SP>2</SP> of the two end rollers C of the housing A each carry at one end a bar F, extending towards the housing B and formed at the end with a hinge part. The other end of the pivot pin carries a spring clip G guided by abutments A<SP>1</SP> of the housing A. Through vertical slots in the side walls of the housing B extend transverse plates H which at one end carry the other part H<SP>1</SP> of the hinge engaging the hinge part on the bar F. The other ends of the plates H are formed as hooks H2 engaging slots G<SP>1</SP> in the clips G. Tension springs J are secured at one end to the plates H and at their other end to blocks J<SP>2</SP> adjustably secured to the housing B by screws K. The screws K serve to release tension in the springs to allow the housings to be unlatched. In an alternative arrangement, Fig. 4, the blocks J<SP>2</SP> are secured to rods L moved by cams L<SP>2</SP> operated by levers L<SP>3</SP>. In a modification, Fig. 6, the screws K are replaced by screws M, which may be dispensed with or replaced by pivoted arms, and the latch comprises a U-arm N engaging the hook H<SP>2</SP> and moved by a pivoted lever N<SP>1</SP> constituting a toggle.

Title: Improvements in or relating to current transformers
IPC: H01F38/28
Filed: 1926-09-15
Abstract: 259,198. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Peters, J. F.). Oct. 1, 1925, [Convention date]. Transformers. - Relates to current transformers and consists in an arrangement for eliminating the effect of magnetizing current so as to obtain proportionality between the primary current and the current in the circuit of the measuring instrument. The arrangement comprises a main transformer unit having a primary winding 2 and secondary winding 4, and an auxiliary transformer unit having a primary winding 3 and secondary winding 5. The two secondaries are connected in series and are connected to an auxiliary load 7 comprising reactance and resistance. The measuring instrument 6 is connected across the main secondary winding 4 so that the current through the instrument is equal to the difference between the currents in the two secondary windings. By suitably dimensioning the iron in the two cores and the characteristics of the load 7, the arrangement is made such that the magnetizing currents in the two transformer units when considered in terms of secondary current are equal and neutralize each other in the circuit of the measuring instrument. The two cores may be combined in the form of a three limbed core having one primary and two secondary windings, and a tertiary winding may be employed instead of direct connection for effecting subtraction of the secondary currents.

Filed: 1933-08-15
Abstract: 423,748. Television. WILSON, J. C., BRAY, T. E., and BAIRD TELEVISION, Ltd., 58, Victoria Street, London. Aug. 15, 1933, No. 22787. [Class 40 (iii)] An oscillator 8 for providing saw-tooth waves to a cathode-ray tube is controlled by synchronizing signals passed through a circuit including a motor-generator 3. Synchronizing signals of line-scanning frequency are applied by a transformer 6 to a coil 2 in the grid circuit of a valve 1, in the plate circuit of which is a second coil 4 coupled to the toothed disc 3. The coils are adjustable about the axis of the motor for phasing, and the polepieces are shaded to make the motor self-starting. An extra winding 7 controls the gas-discharge relay 8 of an oscillator as described in Specification 420,091. The motor drives a commutator 10 to discharge a gas-discharge relay 9 at the picture frequency. The contacts 13 on the commutator are adjusted to adjust the relative phase of the two oscillators. Alternatively, the synchronizing signal is at the picture frequency, and the commutator produces the line frequency.

Abstract: 389,475. Solidification of carbon dioxide. FOSTER, F. H., Kinsah, South Avenue, Littleover, Derbyshire, and PRIESTLEY, W. C., 64, Duckworth Lane, Bradford, Yorkshire. Aug. 13, 1931, No. 22839. [Class 8 (ii).] In apparatus for the formation of solid carbon dioxide from the liquefied gas, the solidification chamber comprises a base 2 and a hinged cover 1, which are clamped by means of links 5 from a lever 4 pivoted at 9. One link 5 is operated by a handle 6, carrying a roller 7 which engages a lug 8 on the cover. The handle consists of two parts 6, 6x. The part 6x has a socket 6y which may be engaged with the part 6a with a member 39 having a pin-and-slot engagement with the part 6, as shown. The handle is utilized for operating a plunger 22, which opens a valve 17 admitting liquid carbon dioxide from a passage 15. The plunger 22 is held in the depressed position by spring dogs 28 engaging a groove 27. As solidification proceeds, the pressure acting on a diaphragm 38, having a wire gauze covering 37, raises a sleeve 30 against the action of a spring 32. The sleeve engages inclined surfaces 29 on the dogs 28 and releases the plunger 22. The valve 17 is thereupon closed by a spring plunger 20. A gradual escape of gas is permitted by passages 36 and a felt packing 35 in a groove in a ring 34.

Title: Improvements in or relating to photochromic materials
IPC: C08L39/00
Filed: 1969-05-07
Abstract: 1,205,907. Photochromic materials and uses thereof. AMERICAN OPTICAL CORP. 7 May, 1969 [12 Sept., 1968], No. 23230/69. Heading C4S. A photochromic material for a light activatable variable density optical filter and image data processing systems for example, comprises a plastics matrix having dispersed therethrough a leuco phenothiazine dye and a reversible reducing agent for the dye. The dye may be Toluidine Blue O, Thionine, Azure A, Azure B, Azure C, Methylene Blue, New Methylene Blue, Toluidine Blue, Methylene Blue MT or Thionine Blue, the reversible reducing agent stannous chloride, titanous chloride or sodium dithionite, and the plastics matrix which may be transparent or translucent may be a polyvinyl acetate, polyvinylpyrrolidone, polyvinyl butyral or polyvinyl formal resin. In preparation, the dye in its oxidized form is dissolved in a polar solvent (e.g. methanol and alkyl alcohols such as butanol and low molecular wt. glycols). The reducing agent added in amount sufficient to reduce the dye to its leuco form (preferably 2 grms. of dye in 90 grms. of methyl alcohol), a plastics soluble in the polar solvent is added and the solvent evaporated. Decolorizing charcoal may be added prior to addition of the plastic. The incorporation of plasticizers such as glycerine and dimethylphthalate produces a less brittle film, increases the photoresponse and controls the viscosity. High viscosity mediums have high resolution, glycerine plasticizer additions lowering the viscosity and resolution but increasing the sensitivity. Absorption in the 550 to 700 nm. range is instanced.
