Patent GB-594378-A (GB)
Title: Improvements relating to plasticisers for thermoplastic compositions
IPC: C08K5/10
Filed: 1945-06-25
Abstract: Thermoplastic compositions comprise an organic derivative of cellulose which is soluble in organic solvents and, as plasticiser, a mixed ester of a primary glycol with a saturated fatty acid and a monobasic aromatic carboxylic acid free from aliphatic unsaturation. Cellulose derivatives include the acetate, propionate, acetate stearate, acetate butyrate, and ethyl cellulose of moderate or high ethyl content.  Glycols include ethylene, 1,3-propylene, 1,4-butylene, diethylene and triethylene glycols or alkoxy or alkoxy-alkyl derivatives, e.g. 2-methoxy-1,3-propylene glycol.  The fatty acid component is preferably acetic, but others, e.g. propionic or a butyric acid, may be used.  The aromatic acid is preferably mono-nuclear, especially benzoic, but may be an alkyl benzoic, e.g. methyl or p  ethyl benzoic, or halogen-substituted acid, e.g. a chlorbenzoic acid, or aromatically substituted lower fatty acid, e.g. phenyl-acetic.  A partial ester of the glycol with one acid may be further esterified with the other acid, acid chloride or anhydride. Alternatively, the ester of a glycol halohydrin and one acid may be heated with the other acid or a salt thereof. Thus, b -chlorethyl benzoate, made by passing ethylene oxide into benzoyl chloride containing aluminium chloride or other Friedel-Crafts catalyst at 40-70 DEG  C., is heated with sodium or potassium acetate to give ethylene glycol acetate benzoate. Another method of preparing the mixed ester is to form the diester of the glycol with the more volatile acid, by refluxing the glycol and the acid or anhydride or by heating an epoxide with the acid anhydride in presence of aluminium chloride, and heating the water with the other acid or derivative thereof.  Thus, glycol diacetate, preferably in molar excess of 1.5-2.5 : 1, is heated at 220-240 DEG  C. with benzoic acid and a dehydrating catalyst, preferably in a still without a column and with a glass or enamel lining.  In examples: (1) ethylene oxide is introduced into acetic anhydride at 140-160 DEG  C. containing aluminium chloride, and the ethylene glycol diacetate formed heated with benzoic acid to give the acetate benzoate.  The di- and tri-ethylene glycol esters are made similarly; (2) b -chlorethyl benzoate is prepared by passing ethylene oxide into benzoyl chloride containing aluminium chloride at 50-60 DEG  C., and heated with the molar equivalent of sodium acetate at 150-180 DEG  C., ethylene glycol acetate benzoate being recovered by fractionation; (3) comparative figures for tensile strength, elongation at break, and water solubility are given for films of cellulose acetate containing ethylene glycol or diethylene glycol acetate benzoate or dimethyl phthalate as plasticiser.  The Provisional Specifications describe also the use of esters of glycols containing secondary or tertiary amino groups, e.g. di-(b -hydroxyethyl)-amine or methylamine, and the application of the mixed esters as plasticisers for other polymeric substances, e.g. polyvinyl compounds.

MITCHELL, R., 69, Kenilworth Court, Putney, London, FINLAY, W., 24, Mansion House Road, DOUGAL, D. and DOUGAL, A., 18, Hill Street, both in Edinburgh, (Representatives of Mitchell, J.), and COSSEY, J. C. G., Calbourne, The Vale, Golders Green, London. June 9, 1932, No. 16315. [Class 103 (v).] In a buffer for railway &c. vehicles of the hollow plunger and cylinder type in which the head f<1> of the spindle f is inserted from the rear or open end of the plunger b into a pocket a<1> formed in the rear of buffer head a, relative rotation between the spindle and buffer head is prevented by means of a suitably shaped plug, adapted to engage similarly shaped holes or recesses in the buffer head and spindle and preferably inserted through a hole in the buffer head. In the construction shown in Fig. 1 a plug h having a square or other non- circular end is screwed through a central aperture in the buffer-head into engagementwith a correspondingly shaped recess in the spindle head f<1>, the plug being finally riveted or beaded over or welded at the front to secure it and the spindle f against rotation. In a modification, Fig. 2, a filling-piece l of square section is inserted through a hole m in the buffer-head so as to engage the recess j in the spindle head, then the latter is moved to a central position in the pocket a<1>, while the filling-piece l simultaneously passes into a recess n in the buffer-head. If desired, the hole in the buffer-head may be subsequently closed by a rivet, while in a further modification, the filling-piece l may be inserted in the recess j. before the spindle f is inserted in the plunger, in which case the hole in front of the bufferhead is unnecessary.

Title: Apparatus for displaying digitally coded data on cathode-ray tube screens
IPC: G09G1/22
Filed: 1960-05-09
Abstract: 935,842. Television. A. B. DICK CO. May 9, 1960 [May 8, 1959], No. 16368/60. Class 40 (3). In a system of the kind wherein characterrepresentative digital signals are converted to analogous character-selection deflection signals which are applied to a monoscope tube to produce video signals applied to a cathode-ray tube (C.R.T.) within a television receiver to which deflection signals are applied to form a television raster including for each line of characters to be displayed on the C.R.T. a separate means for storing character-representative digital signals for the associated line, means derive characterrepresentative digital signals from the separate means for storing in the same sequence as the C.R.T. deflection signals occur, means generate and apply sweep signals to the horizontal deflection circuit of the monoscope at a frequency equal to the product of the frequency of the horizontal sweep signals of the C.R.T. and the number of character positions in each line of the display, and means generate vertical sweep signals at a frequency equal to the product of the frequency of the vertical sweep signals of the C.R.T. and the number of lines of characters to be displayed. In the embodiment described each character is represented by six binary bits, television receiver 42 is of the usual American domestic type, there are six character-positions per line, and the display is four characters per line and four lines thereof. Digital signals from source 10 are applied to line-selection circuits 12 which apply six-bits-per-character signals to registers 14A . . . 14D each of which comprises six parallel-operating shift registers, each register storage capacity being that corresponding to one line of characters. Timing circuits 20 provide shift pulses to the registers, signals instructing selection circuits 16, horizontal and vertical synchronizing signals for addition to the output of video amplifier 34, and control of monoscope 26<SP>1</SP> sweep circuits 22. Circuit 24 is provided to switch on the monoscope tube beam whenever a character on its target is to be scanned, Fig. 4 (not shown). Since several scanning lines of the television receiver are required to display one line of characters each one of the line shift registers cycles its contents a number of times; in the embodiment each one of the registers cycles its information at all times but selective shifting may alternatively be employed. Circuits 16 select the output of the line shift register required for the line of characters to be displayed at the particular time. Three of the binary bits are applied to circuit 26, and the other three to circuit 28, in order to position the monoscope beam to the selected character. The circuits of units 12, 14 and 16 are described with reference to Fig. 2 (not shown), and the timing circuits are given in more detail in Fig. 3 (not shown). The decoding circuits 26, 28 are preferably digital-to-analogue converters as described in Specification 865,171. Specification 708,016 also is referred to.

Title: Improvements relating to gyroscopic compasses
IPC: G01C19/38
Filed: 1927-06-20
Abstract: 275,182. Sperry Gyroscope Co., (Assignees of Carter, L. F.). July 28, 1926, [Convention date]. Gyroscopic compasses.-In a compass having means for eliminating the damping factor during a change of course or speed of the vessel so as to prevent the error due to damping during such changes, the elimination is arranged to be effected only when the rate of turning exceeds a given value, and the total turn exceeds a given angle. The Figures show the application of the invention to a compass of the Sperry type controlled by liquid-containers 15 pivoted to the follow-up member 12 and connected by an arm 16 to the gyro-casing 14, the point of connection 17 being to one side of the vertical axis of the casing so that the control means also exert a damping torque about the vertical axis. To eliminate the damping the arm 16 is pivoted at 18 on the container 15 and is adapted to be moved by an electromagnet 20 so as to bring the point 17 on to the vertical axis of the casing. The means controlling the excitation of the magnet 20 are as follows. The azimuth ring 30 is connected through multiplying gearing 31 - - 35 to a governor G carrying a plate 36 which when raised comes into engagement with a roller 40 which is normallv situated at such a distance above the plate that engagement does not take place until a predetermined speed is attained by the governor. The roller 40 is mounted on a bell crank 41 the long arm 43 of which constitutes a switch arm moving over a segment having an insulating part 44 and a conducting part 45. This switch when closed causes excitation of an electromagnetic member 55 of a clutch 50 so that the member 51 which is driven through gearing 53, 54 from the ring 30 drives a disc 56 which in turn drives a disc 57 through a friction coupling 58. The disc 57 carries two studs 60 adapted after a predetermined angle of rotation of the disc in one direction or the other, to close one or other of two pairs of contacts 61 and thus complete the circuit for the magnet 20. The gears 31, 32 may be connected through a lost-motion device so that small yawing movements of the ship are not transmitted to the gear 32. The invention may also be applied to a compass in which damping is effected, as described in Specification 11028/11, by the flow of liquid between two containers In this form the electromagnet 20 is arranged to close a valve and prevent the liquid from flowing. Specifications 215,594 and 290,392 also are referred to.

A machine for producing flanged metal foil caps, e.g. for milk bottles, comprises a reciprocating annular punch 22 and a co-operating die ring 21, into which the punch slides for punching out a cap blank from the metal foil strip 11, and a forming member 29, located within the die ring 21, over which the punch moves to produce a flange around the cap rim. The strip 11 is advanced through a guide slot 12 in a member 13 attached by bolts 17 to a block 15 formed with a bore 14 for guiding the punch body 18. The punch 22 is formed on the inner end of the body 18 and a movable embossing element 24 is slidably mounted in a bore in the body 18. A control rod 25 connected to the element 24 carries a spring 27 adapted to urge the element 24 to the rearward position. The die ring 21 is held in a bore 19 in the member 13 by a removable plate 30. The flanging member 29 is carried on a spigot 33 passing through a coaxial bore in the plate 30. An ejecting ring 28 slidable over the forming member is connected through pins 31 with a movable plate 32 slidable over the spigot 33 and urged inwardly by a spring 34 bearing at its outer end against an adjustable nut 35. After the formation of the flanged cap, further inward movement of the punch body causes the embossing element 24 to be forced against the face of the cap which is backed up for the embossing operation by a resilient pad 37. On retraction of the punch the formed cap is carried therein away from the die, through an opening 45 in a separating wall 46 into a discharge channel 48. Towards the rearmost end of the travel of the. punch the rod 25 engages an abutment 47 and causes the embossing element to move forwardly and eject the cap from the punch as shown in Fig. 1. A swinging lever 50 is adapted to ride over the punch 22 as it is withdrawn and to tap against the cap to prevent it sticking to the element 24. Specification 736,504 is referred to.
