Title: Improvements in or relating to hardening of unsaturated polyester compositions
IPC: C08G63/685
Filed: 1963-12-09
Abstract: A polymerizable composition comprises (A) an unsaturated polyester derived from an a ,BETA-ethylenically unsaturated polycarboxylic acid, a polyhydric alcohol and, if desired, a polycarboxylic acid free from ethylenic unsaturation, or an ester forming derivative of any of these reactants, (B) an ethylenically unsaturated monomer copolymerizable with (A) and (C) an amine having the formula <FORM:0985750/C3/1> where R1 is hydrogen or an alkyl group and R2 and R3 are alkyl groups.  Alternatively the unsaturated polyester (A) may be modified with (C) to give an unsaturated polyester (A1) which may then be combined with (B). Compounds (C) mentioned are 1-dimethyl-aminobenzene-3,5-dicarboxylic acid and its dimethyl and diethyl esters.  The compositions may be hardened with diacyl peroxides and various fillers, dyestuffs, fibrous reinforcing agents and light absorbers may be added.  In the examples:  (1) a polyester is formed from dimethylamino-dimethyl - isophthalate, propylene glycol, phthalic and maleic anhydrides and is then copolymerized with styrene using benzoyl peroxide; (2) A polyester is formed from dimethylamino-dimethyl-isophthalate, phthalic and maleic anhydrides, adipic acid and propylene glycol, mixed with styrene and then mixed with kaolin, asbestine, mica, titanium dioxide and benzoyl peroxide.

Title: Control system for a high speed page printer
IPC: G06K15/10
Filed: 1972-10-23
Abstract: 1412467 Control of printers MULLARD Ltd 23 Jan 1974 [23 Oct 1972] 48712/72 Heading G4H The invention relates to circuitry for feeding printing signals to a dot-matrix page printer. Each character is in the form of a 7 Î 5 matrix on a 17-line, 64-character page, corresponding characters on each line being built up simultaneously by the simultaneous printing of corresponding dots in each character in the order shown in Fig. 2. The paper is moved continuously so that the printed characters are skewed; each dot in a row may be duplicated for clarity. Each character to be printed is input via K1 in ASC11 code to shift registers SR1, SR2 alternately, and then used to access a dot matrix character generator ROM which outputs a column at a time under the control of a counter Cl. The row dots in each column are selected by gates G13-G19 enabled by a decoder Dl under the control of a column counter C2; ROM is accessed 35 times for the 17 characters to be printed together, when C1 and C2 hold their counts until the required 17 bits have passed through one of G13-G19. These bits are fed alternately to 17-stage registers SR3, SR4 to provide outputs 1-17 via gates G20- G36 or G37-G53 to the print head. A row-scan ROM may be used (Fig. 6, not shown) the choice of ROM also determining the matrix size. The capacity of SR3, SR4 corresponds to the number of lines per page.

Abstract: 1463205 Pipe couplings; valves DEMPCO Inc 12 Nov 1974 [15 Nov 1973] 48942/74 Headings F2G and F2V A fluid flow controlling pipe coupling attachment 10 includes a body 12 having a bore 20 therethrough and end portions configured such that one end will receive a male nipple 11, which includes a check valve 53, whilst the other end, which includes a check valve 34, may be received in a complementary female coupler. A cam 27 is mounted in the body 12 and is movable between an open position (Fig. 2, not shown) when the valve 53 is open but the valve 34 is opened only to a preselected degree, and a closed position (Fig. 3) when the valve 53 is closed and the valve 34 further opened to allow seating of a check valve 62 provided in the female coupler. The movement of the valve 34 is controlled from the cam 27 by means of a guide rod and cam follower 41, 42 and a valve guide 36, the telescoping action of rod 41 into guide 36 being limited. Coupling and uncoupling the attachment 10 may be effected whilst the cam is in the closed position, and excess pressure in the chamber 20A of the bore 20 may be released by operating a bleed valve (not shown) mounted in an opening that communicates with the chamber 20A. The female coupler carries lock balls 66 and a retractable sleeve 67, the balls fitting into a groove 16 of the attachment 10 on mounting. The male nipple 11 has a groove 52 for engagement with set screws 22 provided in the attachment 10.

Title: Cascaded travelling wave tube
IPC: H01J25/38
Filed: 1963-12-13
Abstract: 1,001,719. Travelling wave tubes. RAYTHEON CO. Dec. 13, 1963 [Jan. 30, 1963], No. 49448/63. Heading H1D. An electron discharge device comprises at least two delay lines within a common envelope, an electron beam directed past a first one of the structures and subsequently past at least one further structure substantially uncoupled with the first so as to interact with electromagnetic waves conducted on the structures, and means for extracting energy at two different frequencies from two of the structures. As shown, Fig. 1, a ribbon-shaped beam of electrons 21 passes two interdigitated slow wave structures 7, 15, under the action of crossed E-H fields. The first structure operates as a backward wave oscillator delivering energy at a frequency fo to a load 26, while the second operates as a forward wave amplifier delivering energy at a frequency 2fo to a load 27. In operation, both the slow wave structures and a grid 18 collect electrons which have lost D.C. energy to the R.F. fields. To avoid the first delay line 7 from collecting electrodes, the delay line and the sole electrode 8 may be reversed in position and potential, Fig. 2 (not shown). Two backward wave oscillators working at frequencies f 1 , f 2  may be used, Fig. 3 (not shown). In a further embodiment, Fig. 4, the beam initially passes a backward wave oscillator section 72, the bunched beam then passing two slow structures 75, 79 located side by side and designed for operation at different but harmonically related frequencies, the beam being split into two portions 82, 84 by control electrodes 83, 85. Instead of linearly extending delay line, sole plates and interaction spaces, an arcuate structure may be used, this enabling a more uniform magnetic field to be used.

In the kind of planning-by-network board having a base 1, guide rails 2-8, slidable longitudinal elements Ka to Kf, a time scale 9, and transverse members, e.g. B 1  and B 2  slidable along the guide rails, the transverse members are mounted by means 15, 16 so as to be spaced from base 1 to allow longitudinal elements Ka-Kf to slide freely, but have selector elements, e.g. Cb, Cc, illustrated also in Fig. 7, which can be clipped on to the transverse members and which act as stops limiting movement of selected elements Ka-Kf. As described, the transverse members B 1 , B 2  act as the nodes of the network. A cursor (11), Fig. 17( not shown), is slidable in the longitudinal direction. All the movable parts are removable by distorting the supporting clip means, e.g. 12 in Fig. 2 may be forced off rail 4. Reference has been directed by the Comptroller to Specification 969,157.
