Abstract: 395,555. Typewriters &c. REMINGTON TYPEWRITER CO., Ilion, New York, U.S.A.- (Assignees of Hart, F. A. ; Sagamore Road, Shippan, Stamford, Connecticut, U.S.A.) Oct. 27, 1932, No. 30106. Convention date, Nov. 16, 1931. [Class 100 (iv).] Relay tabulating-mechanism.-The tabulating-keys control means for selectively connecting the associated tabulating-stops to driving-means which preferably comprises a cam adapted to be coupled to a driving- shaft on operation of any of the tabulating - keys. As applied to the computing-typewriter described in Specification 374,109, denomination stoplevers 9, Fig. 4, abut on slides 12 which abut on bell-cranks 38 provided with pivoted links 43 resting on slides 45. Rollers 54 on the slides 45 co-operate with inclines 57 and flats 56, 58 on links 49 connected to denominationkey levers 47, Fig. 7. Guide-combs 39, 39a are provided for the bell cranks, slides 45, and links 49, the comb 39 being formed with hangers for a roller 50 supporting the links 49. The bell cranks and the links 49 are connected to returning-springs 40, 59 respectively. A universal bar 46, co-operating with the links 43, is secured to arms 62 on a shaft 65 and is provided with a roller 69 co-operating with a loose cam 71 on a driving-shaft 72. A spring- urged pawl 75 on the cam co-operates with a toothed wheel 73 fast on the driving-shaft. Rocking arms 79, 80, co-operating with the pawl, are mounted on studs 96 and are connected by a link 99. Normally, the arms are held in raised position by a spring 101, and the arm 80 holds the pawl out of engagement with the toothed wheel. A universal bar 102, mounted on pivots 104, is operated by the links 43, and has an adjustable plate 105 for engaging the arm 79. On depression of any tabulating-key, the link 49 thereof lifts its slide 45 and link 43, and the universal bar 102 depresses the arms 79, 80. Thereupon, the pawl engages the toothed wheel, the cam is coupled to the driving-shaft, and the universal bar 46 co-operates with the link 43 to rock the denomination-stop lever 9 associated with the depressed tabulating-key. When the cam has made a half-revolution, the pawl is disengaged by the arm 79, and on release of the tabulating- key the members are returned to normal position, the cam makes another half-revolution, and the pawl is disengaged by the arm 80. The cam is formed with high parts 71a, 71b which co-operate with the roller 69 to prevent the pawl-spring 78 from turning the cam when the pawl is held in released position by the arms 80, 79 respectively. The denomination-stop levers co-operate with a universal bar which is connected by linkage 20 .. 25 to carriagereleasing means consisting of a rocking arm for lifting the carriage feed-rack.

Patent GB-951150-A (GB)
Title: Manufacture of organo-tin hydrides
IPC: C07F7/22
Filed: 1961-11-07
Abstract: Organotin hydrides are prepared by reacting organotin halides with dialkyl aluminium hydrides in the absence of air and moisture and the resulting organotin hydrides separated from the reaction mixture are freed from organo-aluminium compounds by agitating with water or a solution of alkali metal bicarbonate.  If desired the treatment with water or alkali metal bicarbonate may precede the separation of the organotin hydride from the reaction mixture. Inert liquids may be used as diluents, but a solvent or diluent is not essential to the carrying out of the process. The organotin hydride may be distilled from the reaction mixture.  Dialkyl aluminium halides are produced as by-products, and these may be reacted with tin tetrahalide (e.g. SnCl4) to produce further dialkyl tin dihalide or tetra-alkyl tin which may be reacted with tin tetrahalide to give dialkyl tin dihalide. In order to improve the separating of the alkyl tin hydride the dialkyl aluminium halide may be bound by addition of a complex-forming agent (e.g. an ether or a tertiary amine) in amount at least equivalent to the dialkyl aluminium halide present in the mixture. If desired the complex forming agent may be present from the beginning of the reaction.

Title: Improvements in and relating to a fuze for a gyratory projectile
IPC: F42C15/285
Filed: 1961-11-10
Abstract: 954,691. Ammunition fuzes. HOTCHKISSBRANDT. Nov. 10, 1961 [Nov. 23, 1960; Oct. 17, 1961], No. 40290/61. Heading F3A. A combined percussion and self-destruction fuze for rotatable projectiles, as described in Specification 484,882, is provided with additional safety means, whereby the primer c is held out of alignment with the striker A and moves to the operative position due to the gyration of the projectile, the primer being mounted in a carrier which divides its housing into two chambers in communication one with another through narrow channels around the carrier. Furthermore the two chambers contain a liquid damping the motion of the carrier B. Differences in volume of the liquid due to changes in temperature are compensated by compressible plugs 40c, e.g. of foam rubber, housed in cavities 40b, which communicate with the carrier housing through escape passages 40a formed by flats machined in the screw-threading by which fuze casing part 2 is secured in easing part 3. The carrier B, which is mounted on a pivot 41, is held in the retracted position by a spring 42 and is made in two parts 43, 44 of differing densities. The part 43 may be of a light-weight material such as a light alloy or a superpolyamide and the part 44 of a heavier material such as silver, brass or titanium carbide, so that as the projectile rotates a torque is produced tending to swing the carrier to the operative position. Two members 47, 47a, Fig. 3, fixed to the casing limit the channels n 1 , n 2  between the chambers m, n formed by the carrier to control the displacement of the liquid 55 from the chamber m to the chamber n. The liquid 55 is preferably a silicone. By selecting the appropriate clearances between the chambers and the viscosity of the silicone, the time taken by the carrier to reach the firing position can be regulated.

Filed: 1968-08-23
Abstract: 1,172,486. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Aug., 1968, No. 40359/68. Heading H4F. In a circuit for separating the chrominance signal of a colour television system N.T.S.C. or PAL, into colour information signals and phase reference signals, the chrominance signal is fed into a multivibrator arrangement which switches the signal to a phase comparator 10 during the colour burst period and to synchronous demodulators 12 during the colour information period. The chrominance signal is fed via a transformer 2 to a push-pull amplifier comprising transistors 3 and 4. From this outputs are taken from transistor 3 to transistors 5 and 8 and from transistor 4 to transistors 6 and 7. The two pairs of transistors 5, 6 and 7, 8 form a multivibrator which may be triggered or synchronized at terminal 51. In the embodiment illustrated the multivibrator is of the monostable type, due to the presence of capacitor 14 and hence requires trigger pulses at 15. These pulses are arranged to switch transistors 5 and 6 on, and 7 and 8 off, during the colour burst interval so that a signal passes from transistors 3 and 4, through transistors 5 and 6 to a pushpull transformer 9 from which the signals are fed to a phase comparator 10. Similarly during the colour information period, transistors 5 and 6 are switched off while transistors 7 and 8 are on.
