Title: Diazotype reproduction layer
IPC: G03C1/60
Filed: 1974-03-29
Abstract: 1469941 Diazotype process ANDREWS PAPER & CHEMICAL CO Inc 29 March 1974 [10 April 1973] 14037/74 Heading G2C A diazotype reproduction process comprises imagewise exposure of a diazotype reproduction sheet which has, on a base sheet 10, a surface coating 14 of diazotype components formed in a matrix of spherical particles 12 of polystyrene of diameter of from 0.1 to 1 micron and development of the image thus formed. The surface coating may include a development aid, e.g. urea, that releases ammonia on heating. The surface can be rendered water fast and water repellent by treatment with a solvent or solvent mixture which swells or partially dissolves the spherical particles without dissolving any of the diazotype components. A similar effect can be achieved by partial fusion of the spherical particles. The particles may be applied as an undercoat, the diazotype solution being applied in a second operation or a mixture of particles and diazotype solution can be applied in a single coating operation. The particles can be held together and affixed to the support by a bonding aid such as polyvinyl acetate or copolymer lattices and/or hydrophilic colloids, or by heating the particles or by applying solvent. Other resin dispersions e.g. vinyl acetate, vinyl chloride, vinylidene chloride, styrene, acrylic, styrenebutadiene or ethylene polymers or copolymers, hydrophilic colloids, starch particles, mineral pigments and organic plasticizers may be admixed. Base paper coated with the diazotype composition admixed with the polystyrene particles may be coated on the back with the particles with or without an additional binder. After drying a treatment with a solvent gives a water resistant material. Transfer to a non-treated receiver sheet, e.g. of bond paper, can be effected of the developed image layer. The non-developed layer can also be transferred to a transfer sheet which can be treated before or after transfer to produce image development. The process can also be applied to multicolour diazo reproduction. A solvent treatment is applied to render the surface of the material non- water receptive. After the first printing and development in one colour the developed layer is resensitized with the diazo components for another colour, the solvent treatment is repeated and a second printing and development are carried out, the process being repeated to achieve the required number of colours.

Title: Improvements in and relating to dynamo-electric machine windings
IPC: H02K15/04
Filed: 1949-05-26
Abstract: 670,105. Insulation for dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. May 26, 1949 [May 29, 1948], No. 14126/49. Class 35. The slot conductors for a dynamoelectric machine are insulated by extruded material so disposed about the individual conductors as to provide the appropriate thickness for strand, turn and whole coil insulation, thus avoiding the necessity for applying this insulation at various stages in the winding operation. The conductor may be initially bare or covered and is covered with suitable mouldable plastic, examples of which are given, by passage through a suitable extrusion head. As shown, these conductors are grouped to form layers which in turn may be wound into coils for insertion into slots after further insulation at the top and bottom of the coil has been bonded into position by heated rollers. The coils are formed on mandrels and subsequently shaped to fit the slots in a conventional manner. In a modification several conductors which .have been already insulated by extrusion or wrapping may be given an outer covering by means of extrusion. When the coil is wound, an extruded covering may be given by means of an arc-shaped extrusion head. Specifications 396,354 and 594,481, [Group IV], are referred to.

Filed: 1942-10-08
Abstract: 561,219. Winding yarn &c. UNIVERSAL WINDING CO. Oct. S, 1942, No. 14139. Convention date, Nov. 28, 1941. [Class 120 (ii)] In a yarn or like winding machine, a measuring device, for initiating the operation of a stopping mechanism when the package being wound reaches a predetermined diameter, comprises a member actuated, or adapted to be actuated, continuously by the drive of the machine and movable bodily by and with the growth of the package being wound ; the member may be continuously reciprocated endwise and may move into engagement with a stopping member controlling the stopping mechanism when the package reaches the predetermined diameter. As shown, the traverse guide is carried by a traverse frame 13 pivotally mounted on the traverse cam-shaft 6 so as to swing away from the winding spindle 5 as the package grows and the starting and stopping mechanism of the machine are as described in Specification 492,223 ; the member 50, initiating the operation of the stopping mechanism, has a circular hub 51 at one end rotatably mounted on an eccentric 55 formed as part of the toothed disc fixed on the cam-shaft 6 for engaging the end of a balanced lever 41, which when the yarn breaks or becomes exhausted, moves so that its arm is engaged by one of the teeth of the disc, the lever 33 being then lifted to release the detents 31, 32 and cause the stopping mechanism to act to stop the machine. The other end of the member 50 is formed with a shoulder 57 and with a slot 59 by which it is connected to the back of traverse frame 13 by a shed 62 so that the member can reciprocate relative thereto, a spring 68 being disposed between the member and the frame so that the upper end of the member may be adjusted towards or away from the frame by turning a nut 66, the eccentric 55 being mounted on a bearing that permits this adjustment. A sizing gauge 70 carrying a hardened steel block 75 is adjustably fixed on the lever 33 so that when the package reaches the predetermined size, the member 50 has been moved away from the winding spindle to a position in which the shoulder 57, during reciprocation of the member, comes into contact with the edge of the block 75 and lifts the lever 33 to release the detent 31, 32 and stop the machine as before.

IPC: B64C13/24
Filed: 1962-04-13
Abstract: 969,269. Aircraft instruments and controls. FERRANTI Ltd., and O. B. ST. JOHN. April 5, 1963 [April 13, 1962], No. 14300/62. Headings B7G and B7W. An aircraft control system comprises a limited authority autostabilizer 5 in the control run 3, 6, between the control column 1 and a member to be operated, a computer 7 controlling the autostabilizer 5, a flight director display 11, or an autopilot, Fig. 2 (not shown), controlled by a computer 12 which incorporates stabilizing functions similar to those built into the computer 7, and feed-back means, e.g. a pick-off 15, which during correct operation of the autostabilizer supplies signals to the computer 12 to reduce or eliminate the stabilizing content of its output. Normally, therefore, the demands presented on the flight director display or made by the autopilot are those needed for long-term control of the flight path, but should the autostabilizer fail, the output of computer 12 will then automatically include stabilizing terms which are not cancelled by the feed-back from pick-off 15, and the pilot, following the display, or the autopilot, will automatically perform the autostabilization whether or not the autostabilizer is known to have failed. The feed-back signal may be obtained by summing signals from the autostabilizer and the control column, and the feed-back path may include a wash-out device.

Title: Two-state two-transistor circuits
Inventor: ALLMARK REGINALD HUGH
IPC: H03K3/286
Filed: 1963-04-11
Abstract: 1,073,376. Transistor switching circuits. ENGLISH ELECTRIC CO. Ltd. April 10, 1964 [April 11, 1963], No. 14517/63. Heading H3T. The outflow of base charge when a saturated transistor is switched off is used to assist the switching on of another transistor. When transistor 10 of a cross-coupled bi-stable pair shown is conducting a positive triggering pulse of sufficient magnitude applied via terminal 21 to the primary winding of transformer 20 will cause a biased diode 28 connected to the secondary to conduct. This lowers the apparent primary impedance so that the pulse initiates the removal of the base charge and thus the switching off of the transistor. The reverse base current induces a voltage in the secondary which assists in switching on the other transistor and the conducting condition of the transistors is thus reversed. When the length of the triggering pulse or the withdrawn base charge is insufficient to saturate the other transistor the dotted circuit may be added to provide additional switching current.

Abstract: 1480879 Rotary positive-displacement fluidmachines; treating I C engine charge KLOCKNERHUMBOLDT-DEUTZ AG 9 April 1975 [13 April 1974] 14549/75 Headings F1B and F1F In a rotary I.C. engine "cracked" gas from a "cracking" carburetter 30 is mixed with air in chambers 33, the mixture being compressed in said chambers by the piston 1 during an initial part of the compression phase, and a portion of the mixture being supplied to the carburetter during a later part of said phase for use in the cracking reaction. The engine may be of the epitrochoidal-piston type and have a second piston 2 attached rigidly to the piston 1 by a sleeve 26 encircling a common eccentric 3, the piston profiles being identical. The chambers 33 are charged with air by way of intakes 48, 49, ducts 50, 51 in housing parts 6, 9, apertures 19 in the piston outer-sides, passages 17 and apertures 15 in alternate lobes 14 of the pistons, which lobes also contain exhaust apertures 16. The air is partly compressed in the chambers 33 before cracked gas is introduced through a manifold pipe 37, branch pipes 39, apertures 41 in combined housing-parts 7, 8, apertures 44 in the piston innersides, and apertures 52 in the lobes 14 alternating with the lobes containing the apertures 15, 16, When compressed somewhat a portion of the air and cracked-gas mixture is delivered to the carburetter by way the apertures 44, 52, apertures 42 in the parts 7, 8, branch pipes 40 and a manifold pipe 38. The remainder of the mixture undergoes further compression before ignition in the said chambers. The exhaust gases issuing through the apertures 16, passages 18, apertures 20 in the piston inner-sides, annular gaps 28 between the parts 7, 8 and sleeve 26, and an annular chamber 25 heat the carburetter and pipes 37-40. A fuel and catalyst mixture is supplied to the carburetter through an inlet 53. A portion of the combustion products may be supplied to the carburetter, for use in the cracking reaction, by way of the apertures 44, and additional apertures 36 in the parts 7, 8.
