Abstract: 1277247 Propellant charges DYNAMIT NOBELAG 3 Sept 1969 [4 Sept 1968] 43698/69 Heading F3A  A caseless propellant charge for use in boltfiring appliances percussion devices, control elements and quick action switches, comprises a combustible explosive charge having a firmly adhering outer layer capable of protecting the explosive charge against unintentional ignition or combustion and also against contamination and absorption of moisture, the outer layer being capable of ashless combustion during combustion of the propellant charge. The explosive charge is nitrocellulose, polyvinyl nitrate, nitroguanidine or nitropenta. The outer layer is produced by degradation of the surface of the charge with a sulphide or hydrosulphide solution. In addition to, or instead of, this surface treatment, the protective layer is constituted by a resin which is formed by chemical reaction in situ or is deposited from a volatile solvent. Examples of suitable resins are polyurethane, polyglycide, polyacrylates, polybutadienes, polyvinyl acetate, methylcellulose, cellulose glycollates, aromatic glycide ethers, polyethylenepolyvinyl acetate polymers. The resins may be applied by dipping, brushing, precipitation or applied as foil during moulding of the explosive charge. In an example, moistened fibrous nitrocellulose is moulded into the form of a tablet with a depression in one side and a few drops of priming liquid are introduced into the depression and absorbed by the fibres. The tablet is then drawn through a bath consisting of a mixture of polyester glycol, toluylene diisocyanate, dimethyl glycol phthalate and methylene chloride. After drying the tablet is heated to produce the adherent outer layer.

Abstract: 1,154,739. Substation apparatus. STANDARD TELEPHONES & CABLES Ltd. 28 Sept., 1967 [30 Sept., 1966], No. 43820/66. Heading H4K. An impulse transmitter, particularly for use in a subscriber's set, includes a key set, a capacitor which is chargeable to a level that is dependent on the value of an operated key, and, an impulsing means which charges/discharges the capacitor in a number of equal steps to the level of charge it had originally and which simultaneously transmits an impulse to line at each step. The transmitter includes a multicell battery E1-E10 which is charged via a full wave rectifier (Fig. 3, not shown) from the exchange when the associated handset is onhook. When the handset is off-hook the battery is disconnected from the line and connected inter alia to a multivibrator T1, T2 (100 msec. P.A.P.). Operation of a spring-loaded-lever or push-button key K1-K10 causes capacitor C1 to be discharged to a voltage level which is dependent on the value of the operated key. When the key is released, each pulse from the multivibrator after differentiation by capacitor C5, is used to increment the charge on C1 by one uniform step (the components C5, Dl, T3 act as a constant current source for this purpose). Simultaneously therewith, a pulse is passed via capacitor C2 to monostable circuit T4, T5 whereby impulsing relay A comes up and opens the loop for 66 msecs. Relay B follows to ensure that the operation of another key is ineffective until outpulsing in respect of the digit first keyed-up is completed and an interdigital pause has elapsed.

Filed: 1973-09-19
Abstract: 1396633 Automatic fuel injection control NISSAN MOTOR CO Ltd 19 Sept 1973 [22 Sept 1972] 43917/73 Heading G3N The duration of the fuel injection interval for an I.C. engine is automatically controlled in accordance with a predetermined relationship with inlet manifold pressure for the particular engine, and modified by other measured parameters. As shown (Fig.3), the inlet pressure sensed at 300 produces from converter 311 a primary pulse 376 of proportional width (see Fig.4). The engine temperature, engine speed and throttle valve opening are sensed at 301, 302, 303 respectively and added at 310 in accordance with predetermined information, to produce from converter 312 a secondary pulse 377 of proportional width. Trigger pulses 341, 342 produced by a timing control circuit 351 feed the pulses 376, 377 alternately to a gate 354, allowing clock pulses 378 from pulse generator 350 to count at 355 the width of each pulse 376, 377, to be stored at 356, 358 respectively. The count corresponding to the inlet pressure is also fed via units 367, 366 to control at 352 the frequency of the clock pulses from generator 350 fed to counter 355, in accordance with the predetermined relationship between inlet pressure and injection duration. A further clock pulse train from source 344 has its frequency modified at 359 by the count in store 358 corresponding to the secondary parameters, and is fed to a decremental counter 357, set by the count in store 356. When a synchronizing signal 384 from the engine is received, a flip-flop 360 opens the fuel injection valve for the time taken for counter 357 to be reduced to zero. The throttle opening signal sensed at 303 is modified at 313, 314 to extend the injection duration when the acceleration demanded is large. A further unit 315 inhibits fuel injection in response to a rapid deceleration demand at high speed. (For Figures see next page)
