Abstract: 363,409. Colour photography. NORDMANN, C., Observatoire de Paris, Avenue de l'Observatoire, Paris. Sept. 18, 1930, No. 27958. Convention date, Sept. 19, 1929. Drawings to Specification. [Classes 97 (i) and 98 (ii).] Colour-record images on lenticular films, which may be projected without dominant hues in ordinary projection apparatus, are produced by photographing the object with the colour-selecting filter situated between the object and the anterior focus of the camera objective, so that the axes of the beams of light which reach each lenticular element from the centre of the filter converge to a point at a finite distance behind the lenticular surface ; and printing upon a sensitive lenticular film from the original so produced a contact copy in which, therefore, the axes of the beams of light which proceed from the centre of the image of the colourselecting filter when the copy is illuminated from behind will converge to a point at a finite distance in front of the lenticular surface. On projecting the copy, the colour-selecting filter is placed in front of the copy at this point, as described in Specification 363,387. The " Bistar " lens is referred to as suitable for the camera objective. Specifications 360,524 and 362,490 also are referred to.

Title: Improvements in the manufacture and production of metal carbonyls
IPC: C01G1/04
Filed: 1928-09-29
Abstract: 312,629. I. G. Farbenindustrie Akt.- Ges. May 29, 1928, [Convention date]. Metal carbonyls.-Substances containing metals capable of forming carbonyls, such as ores or metallurgical products are rendered capable of conversion by carbon monoxide by removing or rendering non-injurious easily fusible or slagforming substances such as zinc, cadmium, tin, bismuth, lead, or silicic acid in combination with alkalis, lead, &c. Volatile metals such as zinc or cadmium may be separated by heating the materials in an inert or reducing atmosphere to a temperature at which these metals are volatilized. A material containing iron and zinc may be oxidized, and then reduced, for example by hydrogen which may contain a little water, at 475‹ C. so that the iron but not the zinc is reduced. Fusible metals such as lead, cadmium bismuth or tin are rendered non-injurious by heating the materials containing them until the fusible substances collect in small balls and are not distributed over the whole mass. Slag-forming substances may be removed by flotation or by magnetic separation. In an example, a lead matt containing iron, lead and sulphur is roasted in air to remove sulphur, is impregnated with magnesium sulphate, and reduced with hydrogen at 700‹ C. It is then maintained in the reducing atmosphere at 450‹ C. until the lead collects in balls. The product is treated with carbon monoxide at 200‹ C. and under a pressure of 200 atmospheres.

Title: Process for incorporating additives into polymeric products
IPC: C08F2/00
Filed: 1957-09-09
Abstract: A process for incorporating additives into polymeric products comprises (1) forming a continuous, coherent, porous coagulum by the localized electrolyte coagulation of an electrolyte-coagulable, film-forming polymer latex; (2) washing the coagulum to remove substantially all of the electrolyte coagulant; (3) removing excess water from the washed coagulum without destroying the porous structure; (4) bringing the coagulum into contact with a solution of the desired additive in a non-solvent for the polymer until the solution has diffused through the coagulum; (5) drying the coagulum to remove substantially all of the additive solvent; and (6) fusing the coagulum into a continuous, coherent, integral, polymeric article.  Step (1) may be carried out by casting a metered amount of the latex on to a solid surface wetted with an aqueous solution of electrolyte coagulant, such as magnesium or calcium chloride or aluminium sulphate, and in step (3) the removal of excess water may be carried out by means of an air blast.  The process is particularly suitable for the treatment of latices of polymers of vinylidene chloride and of copolymers thereof with vinyl chloride, vinyl acetate or acrylonitrile.  Additives specified are heat stabilizers such as sodium tripolyphosphate and tetrasodium pyrophosphate, light stabilizers such as phenyl salicylate, 5-chloro-2-hydroxybenzophenone and dibenzoyl resorcinol, and plasticisers such as tributyl aconitate and dioctyl phthalate.

Filed: 1965-07-06
Abstract: 1,108,749. Transistor pulse circuits. CONTROL DATA CORPORATION. 6 July, 1965 [8 July, 1964], No. 28543/65. Heading H3T. A switching circuit feeding an incorrectly terminated twisted pair transmission line is shunted at its input by an impedance which at a voltage level equal to that of the combined sent and reflected signals, has a reduced value equal to the impedance of the line. When transistor 12 is switched off by an input pulse diode 38 becomes conductive to limit the voltage step applied to a twisted pair line 46. The pulse reflected by the relatively high impedance at the far end of the line sees at the driving end an impedance equal to resistor 36 which is chosen to correctly terminate the line. The diode may be the emitter base path of a further transistor amplifier stage (90, Fig. 3, not shown) and the output transistor 60 may feed an AND gate, in which case the lengths of respective lines must be chosen to ensure synchronism.

Abstract: 701,677. Braking apparatus for pithead winding gear. BLACK, G. A. Nov. 12, 1952, No. 28534/52. Class 103(1) In braking apparatus for use with pithead winding equipment, the pivotal axis of each brake shoe is disposed at a point spaced from the nearest end of the brake lining by a distance equivalent to the radius of the brake path, and spaced from the centre of the brake path by a distance equivalent to #2 x such radius, when the angle subtended by the two extremities of the brake lining at the centre of the brake path is approximately a right angle. Curved brake shoes 2, 2<SP>1</SP> are pivotally mounted at 3, 3<SP>1</SP> respectively and conform to the surface of the brake drum 1 having their contacting areas covered with friction linings 4, 4<SP>1</SP>. These shoes may be controlled by a mechanism similar to that described in Specification 691,941. Equal pressure on the drum along the whole length of the co-acting surface is achieved by the fact that the angle subtended at the centre of the drum C by the extremities A and B of the friction lining is 90 degrees, the centre of pressure occurring at D; mid-point of A, B. The correct position for the pivotal axis P of the brake shoe then lies on the tangent to the drum 1 at the point B and at a distance from B equal to the radius R of the drum, the distance of P from the centre of the drum C being #2 x R.

Filed: 1950-11-23
Abstract: 698,950. Pulse shaping circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 23, 1951 [Nov. 23, 1950], No. 28653/50. Class 40 (vi). A pulse-shaping circuit comprises a device to which periodically recurring input pulses are applied which are of such an amplitude that the state of conductivity of the elements of the device changes twice during the incidence of one of the pulses, the output pulses being maintained of constant duration by means of an integrating circuit which is fed with an output from the device and feeds a bias voltage back to its input. Fig. 1 shows a pulse-shaping circuit in which pulses from a source S such as shown at (a) in Fig. 2 are applied via a phaseshifting network T to a valve V1 so that at a level such as shown at (b) in Fig. 2 the valve conducts and at a further level (c) is passing maximum cathode current. Thus an output is obtained from valve V1 as shown at (d) in Fig. 2, part of this is integrated in capacitor C2 and is applied as a bias to the grid circuit of valve V1 to maintain the mean current through the valve substantially constant. The ratio t/T of the pulses shown in Fig. 2 is given by I/n which is equal to that fraction of the total current through resistor R4 which passes through valve V1 when no input is applied to it. The output pulses are thus of constant duration. The pulses to be shaped may be substantially sinusoidal so that when fed through a phase-shifter T the timing of the output pulses may be controlled.
