Title: Improvements in or relating to resinous compositions
IPC: C08G8/20
Filed: 1947-04-02
Abstract: Resinous compositions curing rapidly to form tough, flexible films comprise 100 parts by weight of an unsaturated alkyd resin, 5-50 parts of a polyhydroxybenzene-formaldehyde resin as defined, 1-30 per cent, by weight of the combined alkyd and polyhydroxybenzene resins, of an unsaturated complex ester as defined, and 0.01-2 per cent, by weight of the composition, of a metallic drier.  Suitable alkyd resins are those obtained by reacting unsaturated polybasic organic acids with polyhydric alcohols.  The polyhydroxybenzenealdehyde resin is formed by reacting a 1,3-dihydroxy-5(R)-benzene (where R is hydrogen, hydroxyl, halogen or an alkyl radical and not more than one of the 2, 4, 6 positions are substituted) with anhydrous formaldehyde or its polymers.  There are specified as polyphenols: resorcinol, orcinol, pyrogallol, 1,3-dihydroxy-5-chloro or 4-chlorobenzene, 3,5-dihydroxybenzoic acid, 1,3-dihydroxy-5-methyl benzene. 0.9-1.5 moles. aldehyde (paraldehyde, trioxane, polyoxymethylenes) are reacted per mol. polyhydroxybenzene, the reaction being carried out in anhydrous methanol and with a catalyst to obtain an A stage resin. Complex unsaturated esters specified are o ,o 1-dimethyl-, diallyl-, dibenzyl-ethylene maleate, -diallyl propylene maleate, -tri-(monoallyl maleate) glyceride and their preparation is described (see Group IV (b)). Examples of suitable compositions are: (1) 100 parts diethylene glycol-glyceryl-maleate-sebacate (50 per cent solids in toluene and hexane), 20 parts resorcinol-formaldehyde resin (60 per cent solids in methanol), 10 parts o ,o 1-diethyl ethylene maleate, 1 part metallic drier; (2) diethyl glycol - glyceryl - maleate - sebacate resin, resorcinol-formaldehyde resin, diallyl propylene maleate and drier; (3) glyceryl-maleate-sebacate resin, resorcinol-formaldehyde resin, dimethyl ethylene maleate and drier.ALSO:Complex unsaturated esters are obtained by reacting a polyhydric alcohol with sufficient unsaturated dibasic organic acid to provide one mol. acid for each hydroxyl group of the alcohol and then further reacting the resulting acid half ester with sufficient monohydric alcohol, saturated or unsaturated, to provide a hydroxy group for each free carboxyl group.  Specified reactants are polyhydric alcohols-ethylene glycol, propylene glycol, diethylene glycol, glycerol, pentaerythritol, hexamethylene glycol, trimethylene glycol; acids-maleic, fumaric, citraconic acids, citraconic and maleic anhydrides; monohydric alcohols-ethanol, methanol, propanol, allyl, methyallyl or benzyl alcohols.

Title: Improvements in or relating to control arrangements for electric locomotives
IPC: B60L9/28
Filed: 1952-04-09
Abstract: 719,654. Control of A.C. motors. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. April 9, 1953 [April 9, 1952], No. 9095/52. Class 38(3) A traction system comprises a synchronous motor 15 which also acts as a phase converter and drives a variable speed frequency converter machine 21 having windings supplied with three phase current from the machine 15 and other windings arranged to supply traction motors 25. The traction motors may be of the squirrel cage induction type and are adapted for pole-changing. The motor 15 may drive the frequency changer 21 directly or through an electrical transmission comprising a Ward Leonard generator 16 and motor 20, the generator having a boosting or bucking exciter 50 controlled by a reversing potentiometer 30, 31. An auxiliary frequency converter machine 70 is mechanically coupled to one of the traction motors and has stator windings fed from the supply to these motors. The machine 70 is shown as connected to a pole changing switch 90 so that the number of poles of the machines 25 and 70 are changed simultaneously. The output of the auxiliary frequency converter, which is dependent upon the slip of the traction motor, is applied to a hysteresis motor 71 driving a direct-current tachometer generator 72. A field winding 52 of the exciter 50 is connected to the generator 72 and exerts a modifying influence on the excitation of the direct-current generator 16 tending to reduce the slip of the traction motors. The output of the tachometer generator 72 is also applied to a safety device 91 which may consist of a relay arrangement permitting the traction motors to be connected to the frequency converter only when the output of the tachometer generator is small. In this manner, the traction motors are not energized unless the output frequency of the machine 21 corresponds closely with the speed of the traction motors. The auxiliary frequency converter 70 may be replaced by a number of separate machines of fixed pole numbers, an appropriate auxiliary machine being selected according to the number of poles for which the traction motors are connected. Specification 719,652 is referred to.

Abstract: 1,267,746. Selective printing. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE. 26 Feb., 1970 [26 Feb., 1969], No. 9344/70. Heading B6F. A combination and aggregation type selection mechanism includes a plurality of cranks 25 selectively positionable in an up position as shown or a diametrically opposite down position, the cranks 25 each being coupled by a shaft 24a to a pinion 24 having two toothless sectors 24c, the pinions being normally held positioned as shown, by a spring urged member 241 engaging a flat 24d on the shaft 24, with the teeth 24b on the pinion 24 out of engagement with a toothed section 234 on a longitudinally slidable rack 23. When the position of one or more cranks 25 is to be changed, electromagnets 27e corresponding to those required to be in the up or " 1 " position are energized whereby a corresponding armature 27 engages a two armed lever 26 having toothed ends, the lever 26 being moved so that a toothed end moves either into the path of a projection 234c on the rack 23 (if the corresponding crank is in the down or " 0 " position) or out of the path of the projection 234c (if the crank is in the up or " 1 " position). The two armed levers 26 are each pivoted to a plate 24e fixed to a pinion 24 in the normally vertical diametral plane thereof. The rack is then slid, those levers 26 which are in the path of the corresponding projection 234c being engaged thereby and causing the teeth 24b of the corresponding pinion 24 to engage the toothed seetion 234 on the rack 23 and cause inversion of the corresponding crank 25. Cranks formally in the up or " 1 " position whose electromagnets have not been energized are also inverted. An operated armature 27 is initially latched into leverengaging position by a latch 271 which is disengaged by engagement with a boss 234e on the rack 23 when the rack is slid. The combination selective mechanism operates on a lever aggregation mechanism (Fig. 6) wherein each crank 25 is connected to a rod (2511-2514) which is in turn connected to an aggregation lever (281-283) one of which acts on selection mechanism which may be a toothed segment (282) acting on a pinion (291) mounted on a type wheel shaft for rotational selection, or may act through levers on a parallelogram linkage (39, Fig. 1A) for translational selection on a multiple type wheel printing carriage (5). A hammer carriage (394, Figs. 1A, 1B) causes impression.
