Abstract: 1,209,245. Electric vehicles. J. JARRET, and J. JARRET. 21 March, 1968 [22 March, 1967; 7 April, 1967], No. 13781/68. Heading B7H. [Also in Divisions G1 and H2] A three wheeled vehicle having a castor wheel 10 is propelled and steered by controlling the energization of separate electric motors coupled to respective rear driving wheels, the controller comprising a ball mounted control lever 31. This may be coupled to the sliders of potentiometers (Fig. 4, not shown) connected in a bridge circuit across a battery and arranged to smoothly vary the frequency and polarity of pulses supplied from a separate battery to the motors, using known, undisclosed, circuits. In an alternative arrangement (Figs. 5, 6, not shown) the lever is linked to two pivoted plates having windows by which light reaching photodiodes is varied (see Division G1). The control devices are preferably mounted at right angles, but may be between 60 to 120 degrees, the arrangement being that forward and backward movement of the lever produces equal forward or reverse energization (for braking or reversing) of the motors while sideways movement energizes one motor more than the other. Backward movement may also apply mechanical brakes. The motors may be of the self-commutating, variable reluctance type described in Specification 1,105,767 (Heading H2A). Mention is made of the use of nutual inductors in place of the potentiometers or photo-electric devices described.

Title: Improvements in radio signalling systems
IPC: H01Q5/00
Filed: 1938-05-09
Abstract: 514,778. Electric resonators ; duplex wireless signalling. BRITISH THOMSON-HOUSTON CO., Ltd. May 9, 1938, No. 13838. Convention date, May 7, 1937. [Classes 40 (iii) and 40 (v)] Relates to a system in which an undesired frequency (such as the 35.6 Mc./sec. emission from a police-car transmitter 25) is excluded from a receiver R tuned to an adjacent frequency (such as 34.8 Mc./sec.) by connecting the receiver at a voltage node 31 of the undesired (transmitter) frequency in a coaxial resonator .23. According to this invention the impedance of the receiver is made equal to the surge impedance of the line, and the line may be tune 1 by means of an inductance or condenser 27 so as to present a non-reactive input impedance. The length of an open-ended resonator 23 may be #/2, where X is the undesired wavelength (Fig. 1, not shown) or may be # (Fig. 2, not shown), or any multiple of #/2. If the resonator 23 is short-circuited at the right-hand end, its length may be any odd multiple of #/4 (Figs. 3, 4, not shown). The impedance of the resonator at the input terminals 33 is inductive and capacitive respectively, for desired frequencies lower and higher than the undesired frequency, and may be neutralized by the insertion at 27 of a condenser or an inductance, as the case may be (Figs. 5, 7, not shown). To facilitate tuning and adjustment the resonator may be made slightly shorter than the required fraction of the undesired wave-length, compensation being effected by a shunt condenser 29, Fig. 11, and Figs. 8, 9 (not shown). A similar arrangement may be used at the idle end of the resonator as at 34, Fig. 11, and Fig. 10 (not shown). The impedance of the antenna 24, being low, is mismatched to the input impedance of the resonator and this mismatching helps to eliminate the transmitter frequency.

Patent GB-955488-A (GB)
Title: Preparation of polyether polyols of sucrose
IPC: C08G65/26
Filed: 1961-04-21
Abstract: Polyether polyols are prepared by passing at least one 1,2-alkylene oxide having 2 to 4 carbon atoms into a mixture of sucrose and water in the presence of an oxyalkylation catalyst in an amount of at least 4 moles of alkylene oxide per mole of sucrose, allowing the reaction product to become a liquid at the reaction temperature, discontinuing addition of the alkylene oxide, removing water from the reaction mixture until the water content is less than 10% by weight of the mixture, and then continuing addition of the same or a different alkylene oxide until the desired polyether polyol is formed.  The reaction is preferably carried out at a pressure of not more than 200 p.s.i. and a temperature of 70-270 DEG F. The water may be present initially in the liquid state or as water vapour or steam and may be removed at the intermediate stage by distillation, decantation or centrifuging, Preferably 10-25 equivalents of alkylene oxide are used per equivalent of sucrose. The sucrose may be partially replaced by one or more other saccharides such as lactone, glucose and a -methyl-D-glucoside.  Specified alkylene oxides are ethylene, propylene, butylene and amylene oxides. Numerous catalysts are specified. In examples, using potassium hydroxide as catalyst, sucrose is reacted with (1) and (4), propylene oxide, and (5) propylene oxide followed by butylene oxide.  Comparative examples are given.  The polyether polyols may be reacted with isocyanates to give polyurethanes.

Title: Epoxy modified water soluble alkyd resin
IPC: C08G63/42
Filed: 1959-04-28
Abstract: A water-soluble resin is formed by reacting together (A) a product with acid number 25-80 obtained from (a) a partial ester of a monocarboxylic acid with a glycidyl ether of a di-hydric phenol, and (b) a polyhydric alcohol and a polycarboxylic acid or anhydride, and (B) a neutralizing agent which is a primary, secondary or teriary aliphatic amine or ammonia.  All the ingredients of component A may be reacted simultaneously or the glycidyl ether may first be reacted with the monocarboxylic acid and then with the polyhydric alcohol and polybasic acid.  Suitable glycidyl ethers are available under the names "EPON," "ARALDITE" (Registered Trade Mark) and "EPI-REZ."  The monocarboxylic acid may be a free fatty acid from an oil, or may be added as a natural oil.  Tall oil fatty acids are also suitable. Polyhydric alcohols mentioned are glycerine, ethylene glycol, trimethylolpropane, and 1, 1, 1-trimethylolethane. Polybasic acids and anhydrides mentioned are phthalic, sebacic, azelaic, adipic, succinic and maleic.  Suitable bases are b -dimethylamino ethanol, diethanolamine, diethylenetriamine, triethanolamine, ethylene diamine, propylene diamine, morpholine, piperidine, triethylamine. In Examples (1) and (2) an epoxy resin is esterified with linseed fatty acids.  1, 1, 1-Trimethylol-ethane and phthalic anhydride are added and heating continued.  The resulting alkyd resin with acid member 58 was neutralized with aqueous dimethylaminoethanol; (3) is similar but uses soya fatty acids, and some isopropyl alcohol and butyl "Cellosolve" (Registered Trade Mark) are added at the neutralization stage; (4) is also similar using mixed linseed and tung oil fatty acids and neutralizing with trimethylamine in aqueous butyl Cellosolve.  The other examples are generally similar.  The organic solvent added at neutralizing stage ensures a clear aqueous solution.  Diacetone alcohol may also be used for this purpose.  The modified alkyds are film-forming and become hydrophobic on heating.
