Title: Novel acid anhydrides and the preparation of polyamides therefrom
IPC: C08G69/28
Filed: 1959-03-04
Abstract: A linear polyamide is prepared by reacting a mixed di-anhydride of a dicarboxylic acid free from ethylenic unsaturation and a monoester of carbonic acid with a diprimary amine in a solvent in which the polyamide is insoluble and maintaining the reactants at a sufficiently elevated temperature to complete the elimination of carbon dioxide.  The reaction may be initiated at from -5 DEG  to -40 DEG C. and the temperature raised as the reaction proceeds to not more than 80 DEG C.  The products may be converted by further heating, e.g. at 180 DEG -320 DEG C., to fibre-forming polymers. Polytetramethylene adipamide having an intrinsic viscosity of between 2 and 2-33 when measured in 0,01% solution in m-cresol at 25 DEG C. is claimed per se.  Examples describe the preparation of polyhexamethylene adipamide, polytetramethylene adipamide, poly-m-xylylene terephthalimide and poly-durene adipamide, and the conversion of the poly-hexa- and tetramethylene adipamides to fibre-forming polymers.ALSO:The invention comprises mixed dianhydrides of dicarboxylic acids free from ethylenic unsaturation and mono-esters of carbonic acid, probably of formula R1.O.CO.O.CO.R2.CO.O.CO.O.R1 where R1 is a monovalent radical such as alkyl, aryl or aralkyl and R2 is a divalent radical free from ethylenic unsaturation.  R1 is preferably C1-5 alkyl and R2 preferably a C1-12 unbranched alkylene radical or a phenylene group to which the adjacent carbonyl groups are attached in the para positions.  They may be prepared by reacting a dicarboxylic acid or a metal or ammonium salt thereof with an ester of chloroformic acid.  A hydrogen acceptor, e.g. a tertiary amine is preferably used when p the free acid is employed.  An organic solvent is preferably used and temperatures from about 0 DEG C. to about -60 DEG C.  The anhydrides are reacted with mono- and di-primary amines to produce di- and polyamides (see also Group IV(a)), e.g. N,N1-diphenyl-adipamide, terephthalic acid dianilide, poly-hexa- and -tetra-methylene adipamides, poly-m-xylylene terephthalamide and polydurene adipamide.

Title: Touch-wire systems
IPC: H03K17/98
Filed: 1974-02-19
Abstract: 1490541 Keyboards with coded outputs MARCONI CO Ltd 15 Jan 1975 [19 Feb 1974] 7588/74 Heading G4H A touchwire system comprises conductors TW1, ..., TW32 whose impedance may be altered by touch, means for cyclically gating clock pulses to the conductors in dependence on the count in a counter, and means sensitive to a change in magnitude of the pulses gated to any conductor as a result of a variation of impedance therein for stopping the flow of pulses to the counter so that the count thereof indicates the touched conductor. As shown, a clock controls monostables MP1, MP2 which respectively operate the counter and a decoder. A pulse from an untouched conductor is compared in a discriminator with a threshold voltage 12 and passes through gate OR1 to maintain a monostable MP3 in its astable state. When a conductor is touched, the pulse gated from MP2 is shorted to earth by the capacitance of the human body, and there is no output from the discriminator; thus MP3 returns to its stable state to block a gate AND1, thus freezing the counter output. Removal of the operator's finger from the conductor restores the inputs to OR1 and MP3, which is retriggered, causing a monostables MP4, MP5 to be triggered in turn. The output from MP4 provides a DATA AVAILABLE signal to, e.g. a computer, and the output from MP5 enables gate AND2 for pulses MP2 in case of "dithering" by the operator's finger. A DATA ACCEPTED signal from the computer resets MP4. If this signal has not been received by the time that MP5 returns to its stable state (e.g. when the computer is busy), the short pulse from a monostable MP6 resulting therefrom together with the (still astable) output from MP4 enables gate AND3 to set a flip-flop B1. If another key is touched and released before the data has been accepted, the resetting of MP5 resets B1, a bistable B2 and produce an OVERFLOW signal to warn the operator (this may only be removed by subsequent receipt of a DATA ACCEPTED signal). Receipt of an OVERFLOW bit causes the computer to disregard the last data transfer. The touchwires may be arranged in front of a display to which information is fed by the computer, e.g. for aircraft landing systems, teaching machines or booking offices. The pulses gated to the touchwires may in fact be pulse pairs so spaced that only one of them is affected by interference from the flyback pulses of the associated display.

Title: Improvements in fluid pressure braking apparatus

Filed: 1956-03-16
Abstract: 788,495. Fluid pressure brakes. WESTING- HOUSE AIR BRAKE CO. March 16, 1956 [March 23, 1955], No. 8256/56. Class 103 (1). Fluid pressure braking apparatus comprises in combination a normally charged brake pipe 1, a brake cylinder device 2, a normally charged auxiliary reservoir 3, a normally charged emergency, reservoir 4, brake controlling valve means such as a, triple valve 14 or the like operative to supply fluid under pressure from said auxiliary reservoir 3 to said brake cylinder device 2 upon a reduction in brake pipe pressure, and operative to vent fluid under pressure from said brake cylinder device upon restoration of brake pipe pressure, and accelerated release control means, independent of said brake controlling valve means and controlled by brake pipe pressure to establish an accelerated release supply communication between said emergency reservoir 4 and said brake pipe 1 upon initiation of brake pipe pressure restoration following an application of the brakes. The accelerated release of the brakes takes place in the following manner. When the brake pipe pressure is increased, due to the action of a choke passage 82 through which a quick-action chamber 81 is normally charged from the brake pipe 1 by way of passageway 9, the strainer chamber 7 and the passageway 6, the pressure in a chamber 75 above diaphragm piston 77 quickly preponderates over that in chamber 79 below. The slide valve 84 thus moves down blanking off exhaust choke 113 and unseating accelerated release control check valve 117. This enables brake cylinder pressure from chamber 25 of the quick inshot valve device 26 communicated by way of valve 27, passageways 28, groove 125 in the piston valve 119, passageways 118 and 139 and check valve 140, to be communicated to brake pipe passage 9, and such pressure acts through choke 82 and passageway 80 in chamber 121 above piston valve 119 which is forced downwardly so that groove 124 connects the emergency reservoir 4 by way of passages 20 and 118 also to the passage 9 thus producing a rapid increase in brake pipe pressure which acts upon slide valve assembly 37 to produce a quick initial release of the brakes. The accelerated release produced by the invention is of particular advantage in long trains since by reducing the release propagation time it enables brakes to be released while the train is still in motion without the danger of a break-in-two between the cars.
