Title: Improvements in light sensitive silver halide emulsions
IPC: G03C1/047
Filed: 1959-07-21
Abstract: Carboxymethylated proteins are prepared by reacting the protein with a halogenacetic acid such as bromo-acetic acid at a pH of 9-12.  The protein may be casein, soya bean, blood albumin, edestin, glutin, egg albumin, castor bean protein or globulin, any of which may first be oxidized, or it may be gelatin.  The preliminary oxidation to remove undesirable sulphur compounds may be effected with hydrogen peroxide as described in Specification 648,927.  The treatment with bromo-acetic acid may be carried out in the presence of magnesium oxide, or sodium hydroxide. Specifications 235,211, 522,997, 557,178, 558,710, 560,082, 570,393, 602,158, 602,160, 618,061, 658,592, 618,061, 658,592, 661,645, 663,019, 664,230, 680,593, 682,355, 742,219, 742,221, 742,224, 748,750 and 768,438 also are referred to.

Abstract: 672,606. Tufting-machines. COMYN, B. D. Oct. 17, 1950, No. 25293/50. Class 42(ii). In a machine for securing a blanket of fibres g to a hessian or other fabric base c by forcing a sufficient number of the fibres through the base by means of barbed needles k, two driven rollers m, n are provided close to and on either side of the row of needles to press the blanket and retain it at the required thickness and density. In the embodiment shown, the work is supported beneath the rollers m, n by fixed members q, r, and beneath the needles by a roller e having deep circumferential grooves to receive the needles. The rollers m, n are adjustable, and are grooved to clear the needles, and the roller e preferably has a rough or ridged periphery to grip the base fabric c. The blanket and base pass to the roller m between another adjustable roller f and a roller d. The base fabric is fed intermittently while the needles are out of it, and the fibre blanket is fed continuously. The fibres used may be hair or coconut fibre of any length, straight or curled. Feeding long lengths of fabric.-The base fabric c passes to the machine through intermittently-driven feed-regulating rollers a, b, and away from it between continuously-driven rollers h, i, j, which slip when the fabric is held stationary by the rollers a, b. The rollers d, f are driven intermittently with a and b, and f, m, and n continuously with h, i and j.

[Also in Division G1] A travel measuring arrangement suitable for use in the control of machine tools comprises a scale formed of equally spaced portions 4 of a material of high permeability, and a residing head 1, having gaps 2, 3, which is magnetized by a permanent magnet or by A.C. or D.C. applied to coil 7 at terminals 8, 9 includes a Hall generator 12, and is arranged to traverse the scale. Pulses thus produced are applied to a counter to effect the measurement. The widths of the portions 4 of the scale in the direction of movement are equal, and equal to the widths of the head gaps which are spaced by two units of the scale division or any desired multiple of two units. The scale may be a recessed block of material of high permeability, produced by cutting or stamping, or by etching a foil adhesively secured to a non- magnetic backing. Alternatively the webs themselves may be applied to the backing. A vernier arrangement using a number of heads spaced differently from the scale divisions, in which the magnetization of the individual heads may be switched on or off, is described for positioning the member to which they are attached relative to a member to which the scale is attached, the leading head being energized for setting, with the aid of a counter, to the right section of the scale and another head being subsequently energized say No. 4 of 10 at 9/ 10 th intervals and set for maximum output reading to position the member at N and <SP>4</SP>/ 10 th intervals. The application of the scale to a drum or a disc and the direct use of the machine bed or carriage as a scale are also described.

A flashing-light direction signalling system for road vehicles comprises indicator lamps a on the left and right sides of the vehicle respectively and a selector switch c connected to battery through terminals b and in circuit with a flashing control apparatus comprising in combination a thermally-extensible wire d in series with the indicator lamps, a normally-open electromagnetically-operable switch h in parallel with said wire d, and a normally-open switch f responsive to extension of said wire d for controlling the excitation of the electromagnetically-operable switch h. The contacts fare carried respectively on a resilient strip i fixed at its end j and on an over-centre or snapaction spring strip k fixed at its end m and attached at the other end to the wire d by a glass or other electrically insulating bead n. A resistance e may be included in series with the wire d, and also the winding o of a second electromagnetically-operated switch p arranged to control the circuit of a pilot lamp q as shown. The winding g to operate the switch h is connected as shown. When the selector switch c is moved to the desired side current flows in wire d but not sufficient to light lamps a or operate switch p. When the wire d extends the switch f closes and winding g is energized to cause switch h to short-circuit the wire d and resistance e, thereby lighting lamps a and pilot lamp q. The wire d then cools and opens contacts f to cause the cycle to repeat. The frequency of flashing may be regulated by adjustment of the time of operation of the electromagnetically-operated switch h.
