Title: A non-inflammable substitute for celluloid
IPC: C08L1/12
Filed: 1934-02-21
Abstract: Cellulose triacetate is first mixed with cyclohexanone, methyl cyclohexanone, cyclohexanyl acetate, methyl cyclohexanyl acetate, benzyl acetate, or ethyl acetyl glycolate, in such quantity that the mass, when afterwards heated to 150 to 190 DEG  C., becomes viscous and capable of being moulded or rolled.  The amount of swelling agent employed is, for example, from one to two times the amount of the triacetate, and the temperature during the initial mixing from 120 to 150 DEG  C.  In an example, cellulose triacetate is kneaded with benzyl acetate (or ethyl acetyl glycolate) at 150 DEG  C., plasticizers and a filler are added, and the temperature raised to 180 DEG  C.  In another example, cellulose triacetate is kneaded at 135 DEG  C. with cyclohexanyl acetate, methyl cyclohexanyl acetate, or a solution of glyptal resin in cyclohexanyl acetate, plasticizers and a filler are added, and mixing finished at 165 DEG  C.  A third example is given in which cellulose triacetate is kneaded with cyclohexanone, methyl cyclohexanone, or a solution of vinyl resin in cyclohexanone at 120 DEG  C., plasticizer added, and the temperature raised to 155 DEG  C.  Specifications 179,208, [Class 2 (ii)], and 357,567, [Group VIII], are referred to.

Abstract: 395,806. Calculating- apparatus. LEVKOVITSCH, P. GOUDIME-, La Maion Longa, La Napoule, France. March 1, 1932, No. 6238. [Class 106 (i).] Plane-trigonometry calculators.-A device for solving vector triangles for use on aircraft or surface vessels comprises three spaced arms or equivalents associated with scale and pointer indicators whereby the magnitude and direction of the observed vectors may be set. The ends of the outer arms are operatively connected with the mid arm or so disposed with respect thereto that the ends of the three arms lie in a straight line, the ends of the outer arms being equidistant from the end of the mid arm. The principle underlying the invention is shown in Fig. 1, the sides AB, DA of the triangle ABD represent the direction and magnitude of the velocity of the wind and the course and air speed and the resultant DB represents the ground speed and track. By completing the parallelogram the vectors can be represented by DA, DC, and DE by maintaining AE equal to EC, the scale on DE being half the scale on DA, DC. A constructional form of apparatus is shown in Figs. 3, 4, and 5. A panel 1 has mounted thereon three units 2, 3, 4 each unit comprising an arm 5 with rack teeth 15 engaging a pinion 14 on a setting knob 13 and guided for radial movement in guides 16. The guides are secured to a graduated dial 12 formed with a central aperture to expose scale markings on the arm 5. The dial 12 carries a scale bearing member 19 viewable through an aperture 20 in the panel and is formed with a knurled projection 23 to effect its angular adjustment. The arm 5 and dial 12 are adapted to be held in set position by a locking device 24. The ends of the arms of the outer units 2, 4 carry pivots 9 on which are mounted oppositely disposed rack elements 6, 7 that are engaged by a pinion 8 on the end of the arm of the mid unit 3. To ascertain the course to steer and the ground speed the outer units would be set to the air speed and compass course and wind velocity and direction whereupon the result would be read directly on the mid unit. The panel may be provided with a slide rule 25 graduated to make corrections for height of aircraft. A modified form of the apparatus is shown in Fig. 6, the panel being transparent so that it can be used directly on a chart. The air speed is adapted to be set on a graduated arm 28 carried by a rotatable disc 19, the ground speed and wind velocity are marked off on diametrical scales on the discs 19 of the units 3, 4, the scale ratio being 2 : 1. To the arm 28 is pivoted a graduated ruler 27 with two sets of markings bearing a ratio similar to that of the co-operating disc scales.

Abstract: 1533773 Multiplexing; frame synchronization PLESSEY CO Ltd 7 Feb 1977 [20 Feb 1976] 6708/76 Heading H4M  In a T.D.M. data transmission system of the type having one synchronization bit per frame which is arranged to be the inverse of the immediately preceding data bit, there is provided a frame synchronization circuit which operates by accumulating for each bit in the frame a value indicative of the logarithm of the probability that that bit is the synchronization bit. As shown, the incoming 4 phase D.P.S.K. data stream I/P is used to condition the read-only memory ROM pre-programmed so as to generate incremented logarithm probability values which are applied, as ones or zeros, to control a probability accumulation counter PAC. The counter PAR cooperates with a random access memory RAM which has one location for each bit in a received frame and which is cyclically addressed by a frame counter FC, whereby the addressed RAM location contents are read out into the counter PAC and these contents are incremented by one or zero in accordance with the output of ROM before being loaded back into RAM. The RAM locations therefore accumulate over successive frames the aggregate probability of each bit of each symbol of the frame being the synchronization bit. The cyclic addressing and incrementing continues repetitively for each frame until PAC overflows and generates a frame synchronization pulse FSP to indicate that synchronization has been established.
