Abstract: 1,084,141. Power - assisted steering mechanism. EATON YALE & TOWNE Inc. Jan. 4, 1965 [Jan. 7, 1964], No. 257/65. Heading B7H. A steering system for a vehicle used both on roads and on uneven terrain comprises an hydraulic ram for imparting angular movement to a steerable wheel, means controlled by a steering wheel for directing hydraulic fluid to the ram, and valve means operable to reduce the volume of fluid supplied to the ram for a given movement of the steering wheel. In a shovel loader having steerable wheels 11 linked by a track rod 23 and steered by hydraulic rams 15, 16 supplied from a pump P through control means 25 comprising a control valve 27 and a positive displacement metering device 28 actuated by the steering wheel, a selector valve 35 enables all the fluid to be diverted to one ram 16 when required to provide a higher steering ratio. Lines 31, 32 from the control valve 27 communicate in the normal position of the selector valve 35 with both rams 15, 16. Upon displacing the selector valve 35 the ram 15 is isolated from the lines 31, 32 so that all the fluid is diverted to the ram 16, and both ends of the cylinder of the ram 15 are connected through lines 42, 43 to a reservoir 44 so that no restraint is imposed on steering actions. Displacement of the selector valve 35 is effected against spring-loading 45 by electrical or direct manual means or, as shown, by air pressure supplied from a source 48 through a manual valve 47 to a cylinder 46.

Heading C2C. Alkylene polyamino methylene phosphonic acids of the formula (where R is an alkylene group, R<SP>1</SP> is hydrogen, a hydrocarbyl or substituted hydrocarbyl group, R<SP>11</SP> is hydrogen, a substituted or unsubstituted alkyl group of from 1 to 20 carbon atoms or a phosphomethylene group and n is an integer from 1 to 5) are prepared by reacting together (1) an alkylene polyamine of the formula- R<SP>11</SP>[R<SP>11</SP>NR] n NR<SP>11</SP>H or a hydrate or salt thereof, (2) an aldehyde or ketone R<SP>1</SP>R<SP>1</SP>CO and (3) a phosphorus trihalide, in the presence of more than two moles of water per mole of phosphorus trihalide. The preferred reactants are phosphorus trichloride, formaldehyde and ethylene diamine. However, other alkylene diamines or polyalkylene diamines may be used e.g. diethylene, triamine and hexamethylene diamine, and also substituted polyamines e.g. ethylene diaminetriacetic acid. Specified aldehydes and ketones are formaldehyde, acetaldehyde, chloral, bromal, glutaraldehyde and acetone. Formaldehyde, which is the preferred aldehyde, may be used in the form of trioxane or paraformaldehyde or in the form of its concentrated aqueous solution containing 37% by weight of the aldehyde. The reaction is normally carried out at 30‹ to 60‹ C. and is desirably completed by heating at 100‹ to 120‹ C. for a short time. During the reaction a pH of not more than 2À0 is preferred. If the reactants are not water soluble, a water-miscible organic diluent or an emulsifying agent may be used. The phosphonic acid products may be obtained in the form of metal or ammonium salts by appropriate neutralization of the free acid. Examples describe the preparation of ethylenediamine tetrakis (methylene phosphonic acid).

Abstract: 1,230,343. Digital transmission systems. POST OFFICE. 16 April, 1969 [16 April, 1968], No. 19479/69. Headings H4L and H4P. Word synchronization in a digital data receiver is attained by comparison of a sync. word, transmitted repeatedly prior to the data, with a number of locally generated words each a cyclic permutation of the sync. word. As described, the data consists of 8-bit words and is preceded by four 8-bit sync. words preceded by a bit-rate clock signal. The sync. word chosen displays a good auto-correlation characteristic. When the receiver attains bit synchronization (not described) a pulse at terminal 16 causes gates 24 to be enabled and a word identical to the sync. word (11100100) to be placed in shift register 12. Clock pulses step the register at bit rate and consequently each stage of the register outputs repeatedly an 8-bit word, each word being a cyclic variation of the sync. word (e.g. the word from stage 5 is 10011100). The register stages are connected to respective multipliers 40, forming part of a correlator and which are also fed with the received signal from terminal 14. The multipliers feed integrators 44 and that integrator which is fed by the multiplier connected to the stage of register 12 presenting a signal which is in phase with the received sync. words develops a steadily increasing positive output, all other integrator outputs varying between zero or negative values. At a time after the pulse at 16 determined by monostable 36, decoder 46 enables that one of eight units 52 (two shown) which corresponds to the integrator having a positive output. Thus if the output of stage 5 is in phase with the sync. words decoder 46 enables the fifth unit 52. This unit now outputs a pulse whenever register 12 contains a word identical to that generated by stage 5 (i.e. 10011100), these pulses being in word synchronism with the received words and appearing as a word-rate clock at terminal 58. On occurrence of the first pulse from the enabled unit 52 integrators 44 are reset, gates 28 are enabled, and gates 24 inhibited. The correlator may now be used to correlate the data words with preset messages at terminals 62 (not described).

Abstract: 1,233,570. Making electrical components. TEXAS INSTRUMENTS Inc. 19 Sept., 1968 [27 Oct., 1967], No. 44610/68. Heading B3A. [Also in Division H1] A number of modules for making transformers, inductors, or capacitors are cut from a single bar which has been coated with copper and silver on at least two opposed faces and grooved longitudinally so as to cut through the metal layer. To make capacitors 12 (see Fig. 5), a bar of barium titanate is coated on two opposed surfaces and grooved at 11 to form two capacitors effectively in series and having one common plate 10a which may be partially removed by an abrasive air jet to adjust the capacitance values. These may deliberately be made unequal by offsetting groove 11. Plates 10b, 10c may be soldered directly to a circuit board or to legs of a transformer or inductor core, made as described below, to form a modular tuned circuit. H-shaped cores 7 (see Fig. 3b) for transformers or inductors are made from a high resistivity ferrite bar, coated all round with silver on copper, by forming grooves 3 in two opposite surfaces to leave terminal pads on the core legs 5a, 5b, 6a, 6b. One or both pads may be divided by a further groove 8 to form a pair of terminals. Two bifilar windings 31, 32 wound on the centre of such a core form the primary and secondary of a transformer 30 (see Fig. 11a) which is soldered to terminals A, B on an alumina substrate 15. The winding 31 is connected to terminals A, B through the core terminals and both winding 32 and capacitor plates 10b, 10c are connected by metal strips 33, 35 to terminals C, E respectively. A further strip 34 connects capacitor plate 10a to a terminal D to serve as an impedance tap.
