Title: Improvements in or relating to plastic compositions
IPC: C08K5/03
Filed: 1952-12-19
Abstract: A cellulose acetate plastic composition contains benzene hexachloride as an extender in a proportion of from one per cent by weight up to the limit of compatibility.  The cellulose acetate may contain 30-60.5 per cent of combined acetic acid.  The compositions may be formed into fibres, films and moulded articles.  The incorporation of 10 per cent of benzene hexachloride materially reduces flammability while upwards of 15 per cent produces self-extinguishing compositions.  The limit of compatibility varies according to the composition or nature of the particular cellulose acetate product and the mode of incorporation but is of the order of 25-30 per cent by weight. For comparison, it is stated that the limit of compatibility of benzene hexachloride in cellulose aceto-butyrate and ethyl cellulose is of the order of 5 per cent.  Preferably an insecticidally inactive form of benzene hexachloride is used, e.g. a mixture of the alpha and beta isomers.  Such mixtures are obtained during the manufacture and isolation of the gamma isomer, which is insecticidally active.  Fillers, pigments, dyes, stabilizers and other substances may be incorporated in the compositions, e.g. titanium dioxide and acetate dyes.

Title: Frames for film transparencies
IPC: G03B21/64
Filed: 1961-09-08
Abstract: 925,829. Transparency mounts. J. JOST, [trading as FILMOSTO - PROJEKTION JOHANNES JOST]. Sept. 8, 1961 [Oct. 1, 1960], No. 32291/61. Class 98 (2). In a frame for film transparencies including a first frame member and a second frame member, each member is provided with an aperture corresponding in shape and size to the picture area of the transparency to be framed, the inner surface of at least one member is adapted to receive and locate the transparency, the outer surface of at least one member is recessed around the aperture for receiving a transparent cover-plate, and the frame members are arranged to provide, in the assembled state of the frame, an edge portion protruding above the level of the rest of the outer surfaces of the frame members in the regions surrounding said aperture or recesses, respectively. In a first embodiment (Fig. 2), the frame comprises two frame members 1, 2, each provided with means (not shown) for mutually joining them together and each having a recess 3 for accommodating a protective plate 4 of glass or synthetic transparent material, the transparency 5 being held between portions 1a, 2a of the said members and cut-out portions 1c, 2c being provided for this purpose. Recessed portions 1g 7g are also provided for accommodating holding masks 6, these being secured in position by self-adhesive means or, for example, by cement and being of such dimensions as to overlap the plates 4 and thereby to hold these plates in position. In a modification in which the edges 1e, 2e are undercut and correspondingly shaped plates 4 are used, said plates may be snapped into position and the masks 6 may be dispensed with. Alternatively, if the parts 1, 2 are made of pliable plastics or thermoplastic material, resilient lugs may be formed at the edges 1e, 2e to resiliently hold the plates 4 in position. In the modifications where the mask 6 is dispensed with, the raised edge portions 1f, 2f would serve to reduce the risk of scratching of the plates 4. In a second embodiment (Fig. 3) the mount again comprises two parts 1, 2, but here the part 2 is not identical to the part 1 and is held in a recess in the part 1 by undercut edges 1h or by a mask corresponding to 6 in Fig. 2.

Abstract: 631,231. Screw fans. AEREX, Ltd., REEVES, H. C., and HAIGH, F. S. Dec. 10, 1947, No. 32554. [Class 110(i)] The delivery guide vanes a have straight leading edges d which in a radially outward direction are inclined rearwardly relatively to the direction of rotation of the impeller. The vanes are of laminar section, rounded at the leading edge and tapered at the trailing edge. Alternatively, they may be of solid or hollow aerofoil shape. The vanes are attached at their outer and inner ends to the casing and fairing respectively, either by eyed lugs or by welding. The trailing edges of the impeller blades b and the leading edges d of the guide vanes are oppositely inclined, so that they pass each other progressively, thus reducing noise due to syren effect.

Title: Improvements in and relating to guided missiles
Inventor: VAUGHAN ALFRED JOHN
IPC: F41G7/36
Filed: 1954-11-15
Abstract: 817,672. Automatic steering control systems. ENGLISH ELECTRIC CO. Ltd. Nov. 11, 1955 [Nov. 15, 1954], No. 33076/54. Class 38 (4). [Also in Group XL (c)] In a guided missile control system, the actual and required positions of the missile are compared and the resultant signal used to bring the missile to the required position. The actual position is determined by a doubly integrating accelerometer 41, Fig. 6, and the required position is derived from a signal storage device 40, in the missile. The outputs from both the accelerometer and the storage device are electrical pulse trains, and the number of pulses produced in a period of time represent a distance travelled in that time. The two trains are compared in a pulse discriminator 43, and the output signal is developed at either one of two lines 45, 46 according to which of the input trains is the more rapid. Each line is associated with a ratchet release mechanism 47 which together move a cam-operated variable resistance 49, 50 controlling the missile positioning device 52. The pulse discriminator has no output when the two input trains apply the same number of pulses to the discriminator in a specified period. In one embodiment of the discriminator, Fig. 2, the two pulse trains are applied, at 12 and 13, respectively, to the switches 10, 11. These are normally at position a but on receiving a pulse each switch is moved to position b for the duration of the pulse. If the moving contacts of 10 and 11 are connected to the battery 15 then output pulses will appear at 18, 19. However, the moving contacts of 10, 11 are connected to 15 through the arm of switch 17 and this is moved to contacts c or d accordingly as 17 is pulsed from 12 or 13. Hence, a pulse from 12 moves 17 to c and 10 to b and similarly a pulse from 13 moves 17 to d and 11 to b. Thus if alternate pulses are received at 12, 13 to above sequence is effected continually and no signals appear at 18, 19 as the action of 17 lags the movements of 10 and 11 due to the short period delay line 20. This condition corresponds to the required and actual missile positions being the same. Should the two positions not correspond, the pulses will appear at 12, 13 in groups and consecutive pulses at 12 or 13 will move 17 to the corresponding position and then pulses will appear at 18 or 19 due to the movements of 10 or 11 under the action of its controlling pulses. Should pulses at 12, 13 be rear coincidence, the system does not operate accurately and in a further embodiment, Fig. 4, not shown, rear coincident pulses are eliminated. A coincidence detector closes a gate preceding each switch 10, 11 when pulses in the trains at 12 and 13 are at rear coincidence. When the missile reaches the falling part of the trajectory, this would require representation as a negative pulse rate output from the accelerometers. Thus, in a modification, not shown, a pulse train of fixed frequency is added to the accelerometer's output to give an artificial datum. Specifications 817,671 and 817,673 are referred to.
