Filed: 1961-10-13
Abstract: 1,125,521. Pulse radar. SPERRY RAND CORP. 13 Oct., 1961, No. 36901/61. Heading H4D. In a pulse radar, each transmitter pulse is of low amplitude, long duration and is frequncy swept. At the receiver, the echo pulse is compressed and has a high amplitude and short duration. Targets beyond the normal range may be received by second time round echos. A single band-pass filter 11, is employed to expand and frequency sweep the transmitter pulse and an inversion of the frequency sweep sense is introduced into either the transmitter or receiver, to permit the same filter to compress the echo pulse also described in Specification 906,710. The frequency sweep inversion functions are periodically intercharged in a predetermined manner. A receiver mixer 30 and transmitter mixer 19 are supplied with selectively charged sweep frequencies from the local oscillators 57, 58 by the action of bistable multivibrator 59 through the gates 51, 52, 53, 54. The frequency sweep inversion is effected at each radar repetition interval. Random operation of the multivibrator 59 reduces the effect of jamming.

Title: Valve, e.g. for use in fire extinguishing systems
IPC: A62C13/00
Filed: 1946-12-17
Abstract: 631,600. Fire - extinguishers. SPECIALTIES DEVELOPMENT CORPORATION. Dec. 17, 1946, No. 37175. Convention date, Dec. 18, 1945. [Class 47 (ii)] [Also in Group XXIX] The main valve 60, Fig. 1, controlling the flow of pressure fluid, e.g. for fire-extinguishing, from a container 16 to an outlet 109, is opened against the container pressure by movement of a fluid-pressure member, e.g. a piston 122, and a check valve 124 loosely mounted on the valveactuating spindle 120 prevents the main valve being directly subjected to the pressure in the outlet. A spring-loaded auxiliary valve 78, actuated manually or automatically, controls the flow of fluid from the container through a passage 136 having a non-return valve 138 to the chamber above the piston 122 to open the main valve. A frangible disc 48 held in position by an anti-recoil plug 52 prevents dangerous pressure developing in the container. Several containers and control valves may be connected to a common outlet conduit, and on discharge of the fluid from any container the rise of the pressure in this conduit acts back through the outlets 109, passages 142 and non- return valves 143 on the pistons of the undischarged containers, and thus opens their main valves.

Abstract: 1483608 Teleprinter arrangements; impulse transmitters SIEMENS AG 27 Aug 1974 [29 Oct 1973] 37317/74 Headings H4P and H4K In a teleprinter having a keyboard TA for the input of data, a dialling pulse generator WG is responsive to a dialling selection signal WS and to a signal BW, ZP supplied thereto and emitted by the keyboard TA on operation of a digit key thereof to produce from a pulse train ZT of constant repetition frequency dialling pulses W1 the number of which is equal to a number predetermined by the signal ZP emitted from the keyboard.  The dialling pulse generator WG includes a control circuit ST, Fig. 2, which controls the sequence of the production of the dialling pulses WI and a counter FT which produces pulses IM from the pulse train ZT of a quartz oscillator in a teleprinter control unit FS. The output pulses IM from the counter FT pass via a blocking circuit including an AND gate U1 to provide dialling pulses WI to a remote controlled switching unit FE for connection to the teleprinter line FL. A dialling pulse counter WZ counts the emitted dialling pulses and a comparator VG including a decoder DC and a data selector DS compares the number of emitted dialling pulses WI with the number determined by the signal ZP emitted from the keyboard and when they are equal provides an output VP to disable gate UI to prevent further dialling pulses WI. An interval counter PZ produces a predetermined time interval between two sequences of dialling pulses. After the time interval the output from the counter PZ controls via a gate U5 and a bistable flip-flop F5 a bi-stable flip-flop F4 whose output LO provides a signal to reset the counters FT and WZ. Modulo-2 counters can be used in the interval counter PZ and the dialling pulse counter WZ and counter FT consist of a series connection of modulo-2, modulo-5 and modulo- 12 counters. If a redialling process is required to reach extensions after establishment of a connection the teleprinter is provided with a key NW which emits the selection signal to cause the dialling pulse generator WG to generate a further sequence of dialling pulses. The selection signal causes the signals ZP from the keyboard TA to be fed via the transmitter SE of the teleprinter, the remote controlled switching unit FE and the receiver EM of the teleprinter to the teleprinter printer DR. A NAND gate links the actuating signal of a call light to the dialling pulses to produce a flickering signal.

IPC: C08F2/46
Filed: 1966-08-22
Abstract: A photopolymerization process comprises subjecting one or more ethylenically unsaturated compounds to light radiation having a wavelength in the range 2500-5000 Angstroms in the presence of a photo-redox catalyst system comprising, as a source of photolytically formed ferrous ions, an iron (III) complex double salt and, as oxidizing agent, an oxazirane compound of the formula <FORM:1123103/C3/1> where R is H and R1 is phenyl or C1-C3 alkyl, or R and R1 together with the carbon atom form a cycloaliphatic group, and where R11 is C1-C4 alkyl.  The double salt may be the ammonium iron acetate, citrate or oxalate, or the potassium iron citrate, oxalate, sulphate or tartrate.  Suitable oxaziranes are 2-t-butyl-3-phenyloxazirane, 2 - t - butyl - 3 - isopropyloxazirane and 2-ethyl-3-pentamethylene oxazirane. Unsaturated compounds which may be used include styrene, acrylamide, methacrylamide, acrylic acid, methyl methacrylate, acrylonitrile, N - vinylphthalimide, N - vinylpyrrolidone, vinyl esters and vinyl ethers, as well as polyunsaturated monomers, e.g. divinyl benzene, diglycol diacrylates and N,N1-alkylene-bis-acrylamides, and polymers containing unsaturation, e.g. allyl esters of polyacrylic acid, maleic esters of polyvinyl alcohol, polyhydrocarbons containing residual unsaturation, unsaturated polyesters, cellulose acetomaleates and allylcellulose. Polymerization can be effected in bulk, emulsion, suspension or solution; the polymerizable composition may be coated on a support in order to produce photographic images.  An hydrophilic or hydrophobic binder may be included, e.g. polystyrene, polymethyl methacrylate, polyvinyl acetate, polyvinyl butyral, partially saponified cellulose acetate, gelatine, casein, starch, carboxymethylcellulose and polyvinyl alcohol; where such a polymeric binder is used, it is believed that graft copolymers are formed.  In examples photopolymerization is effected of (1), (2) and (6) acrylamide in aqueous solution, (3-5) and (7-10) acrylamide, triethylene glycol diacrylate, acrylonitrile, acrylic acid or N-vinylphthalimide in aqueous ethylene glycol monomethyl ether, in some cases with the pH adjusted to a value of 5, and (11-12) a dried coating, supported on a polyethylene terephthalate film, comprising acrylamide, N,N1-methylene - bis - acrylamide, pigment and sodium tetradecyl sulphate (moistening agent).
