Patent GB-1060321-A (GB)
Title: Improvements in or relating to polyester resin compositions
Inventor: FILSON ARTHUR COLE
IPC: C08L67/06
Filed: 1965-02-02
Abstract: A polyester resin mix is formed by adding to a mixture of an unsaturated polyester resin, an ethylenically-unsaturated monomer, and an organic acid soluble in the polyester and having little or no tendency to catalyse a vinyl type polymerization, an oxide or salt of a metal capable of reacting as an alkaline compound with a carboxylic acid group, the final mix being maintained at room temperature until gelation occurs to give a highly viscous non-tacky composition. The monomer may be styrene or an acrylic, methacrylic or allyl ester. The composition may also contain a filler (e.g. talc), a stabilizer (e.g. hydroquinone or 1,4-naphthaquinone), a pigment, and a catalyst for a vinyl type polymerization (e.g. t.-butyl perbenzoate). The acid may be rosin, tall oil fatty acids, or benzoic or stearic acid, and may form from 1 to 5% of the mix.  The metal compound may be the oxide, carbonate, or hydroxide of Ca, Ba or Mg.  Glass fibre cloth or mat, sisal, paper, synthetic fibres or asbestos may be impregnated with the mix.

The tube bank assembly may be arranged in a natural draft cooling tower (Figs. 12, 13) or air fans may be provided below the assembly. The steam may flow in either a single or two-pass flow through each tube bank.  In the fan-cooled condenser shown the tube bank pairs, are arranged in spaced-apart rows 19-22, the assembly being supported on legs 11 with the fans 27 disposed below the tubes and each fan supplying air to two of the tube bank pairs. Each said pair is served by two fans, Fig. 4, so that an air supply is ensured if one of the fans is not operating. Each tube bank inlet header has two steam supply ducts 26. Condensate is removed via lines 30, 33 and 31, 34 and non-condensible gases are withdrawn via lines 35. In a modified arrangement (Figs. 7 to 11) the steam is supplied to a primary group (B) of the tube bank pair and uncondensed steam from this group is passed through a secondary group (A) of the tube bank pairs.

Abstract: 640,321. Safety-pins. FULLER, F. C. Feb. 16, 1948, No. 4521. [Class 43] A safety-pin comprises two end housings 10, 11, connected by two wire members 12, 13, the end of one wire 13 being releasably held by a slidable locking member 23 mounted in one housing 11, and the other end of the movable wire 13 being resiliently mounted in the other housing 10 in such a way that said movable wire is urged to the closed position. The ends of the wire 12 are curved round and secured inside the housings 10, 11, the other wire 13 being pivoted at one corner of the housing 10. An S-shaped spring 15 in the housing 10 acts on an extension 14 of the wire 13 to urge the latter to the closed position. The wire 13 is not long enough to reach the corner 16 of the housing 11 but by acting on a transverse portion of an arm 18 in a lever linkage 18-22 causes a slide 23 to move over into a blocking position above the wire 13, To open the pin the slide 23 is moved back and the wire 13 is pulled out against the pressure of the spring 15.

Abstract: 712,267. Automatic regulation. HACKBRIDGE & HEWITTIC ELECTRIC CO., Ltd., and WELLS, R. Nov. 17, 1952 [Feb. 21, 1952], No. 4601/52. Class 38(4) In an overcompounding arrangement in which the output of a grid-controlled mercury arc rectifier is controlled in accordance with the load current, this current is measured by the magnitude of the ripple voltage across an inductance connected in series with the D.C. load. The rectifier 10 has an A.C. input 14 and supplies a D.C. load at 15 via the inductance 16. Since the output is unsmoothed, a ripple voltage appears across the inductance 16, and this is connected via a blocking condenser 18 to an isolating transformer 17 and rectifier 19, whence a D.C. control voltage is applied to the grid phase shifter shown at 23. The condenser 18 and/or the transformer 17 may be omitted. The inductance 16 may, or may not, saturate at full load, according to the particular characteristic required.

Abstract: 115,024. Soc. A n o n . Robinetterie Riunite. March 17, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Projectile fuses.-Relates to percussion fuses adapted to operate either by the firing-pin 2 being driven backwards against the primer 3 by im. pact, or by forward movement of the primer due to inertia, and consists mainly in making the head 1 of the fuse-body hollow so that it may be readily crushed when impact 'occurs. Several forms of safety-devices are described, all the constructions shown embodying a ring of cams 9 pivoted around the primer-carrying pellet so as normally to lock it. As shown in Fig. 1, the firing-pin 2 may be formed with a shoulder 7, so that the cams 9 would prevent the pin from being prematurely driven against the primer 3 by obstructing the shoulder. In addition to an inertia stop 11 for the first cam 9, an inertia stop, not shown, may also be provided for locking the last cam of the series independently. In the modification shown in Figs. 7 and 8, the passage through the primer-pellet is normally blocked by a centrifugal bolt 12, held in place by an inertia sleeve 13.

Abstract: 1,101,643. Frequency changing. FUJITSU Ltd. 3 Feb., 1965, No.4779/65. Heading H2F. A frequency changer of the harmonic generator type comprises a combination of non-linear capacitance (NC) and non-linear resistance (NR) and includes means to vary the phase of the signal of one of these components relative to the other so as to achieve unidirectional transfer of energy. As shown, a source 16 of frequency f, shunted by a filter 14 is connected in series with a non- linear arrangement comprising a parallel combination of non-linear capacitor 11 and non- linear resistor, and a delay line 13 in the resistive branch effects the phase variation. A load Ge energized by the harmonic frequency nf, is shunted by a filter 15. In other embodiments a series combination of non-linear resistance and non-linear capacitance is connected in shunt across the supply. The NC/NR combination may be a single varactor diode, or it may be such a diode in series with a capacitor or in parallel with a resistor or capacitor. In an alternative arrangement, wherein a series NC/NR combination shunts the supply the phase variation is effected by an idler circuit in parallel therewith this circuit comprising a series inductor/capacitor combination. The Specification provides a mathematical analysis of the circuitry introduced.
