Abstract: 1,087,073. Street posts. P. W. TURNER. Nov. 6, 1964 [Sept. 11, 1963], No. 35896,63. Heading E1B.  A lamp or other roadside tubular post designed to yield on lateral impact by a colliding vehicle is divided at ground level into lower and upper parts 11, 12 secured to flanges 13, 14 held together by four bolts 17 engaging open notches in the flanges. The notches 15 are of 60-degree V shape, Fig. 3 (not shown), so that lateral movement of the part 12 in any direction causes the bolts to ride out of the notches. The frictional resistance to such movement is controlled by a lubricant-coated plastics sheet (not shnwn) between the two parts. U-clips 22 are preferably provided for the bolts 17, and each bolt may be yieldably located (a) by a respective end of a pair of crossed diametrical frangible links (18, Fig. 2, not shown); or (b) an individual washer (Fig. 4, not shown) having frangible locating pins  depending into the flange 14; or (c) by modifying the U-shaped clip 22 to include a yieldable locating lug (Fig. 5, not shown). The post may be of steel, aluminium, alloy, wood or resin-bonded glass fibre. The upper part has an access door to electrical control gear, .while the lower part preferably incorporates a switch or disconnecting link to isolate the upper part when moved laterally.

Abstract: 1,109,655. Measuring angular displacement electrically; recording apparatus; voltage measurement. SIEMENS, A. G. Aug. 24, 1965 [Aug. 24, 1964], No. 36396/65. Headings G1J, G1N and G1U. The angular position of a permanent magnet (1), Fig. 1 (not shown), affects the flux in a magnetic circuit containing an indium arsenide magneto-resistive element (5) which together with resistors (11, 12, 13) forms a bridge circuit (10) the output of which is fed through an amplifier (14) to an indicating instrument (15). Coils (6, 7) are fed from a stabilized current source (8) to pre-magnetize the element (5) so that it may operate in a linear region of its characteristic curve. The output of the amplifier (14) may be coupled to the magnetic circuit through (16, 17). In a compensated measuring instrument having a contactless measuring bridge, Fig. 2, a voltage U M  (e. g. from a thermocouple) is in series opposition with the output of a bridge containing two magneto-resistive elements 29, 30 and the difference voltage #U is amplified and fed to a measuring motor 40 which drives a rotatable magnet 21. The pre-magnetizing coils 31, 32, 33, 34 are arranged so that their fluxes cancel in the limb containing the magnet 21. The arrangement shown in Fig. 2 may be used for measuring angle of rotation by omitting motor 40 and connecting the output of amplifier 41 to terminals 46, 47. In a modification, Fig. 3 (not shown), a two phase A. C. measuring motor (50) is used in conjunction with a D. C. to A. C. converter (54). The amplifiers of Figs. 1, 2 and 3 and the converter of Fig. 3 may comprise at least one stage containing a magneto-resistive element in a bridge circuit. In Fig. 4 (not shown), a measuring motor (66) drives through reduction gearing a cable (63) connected to a recording device (59) and an indicator (60) and passing round a pulley (62) mounted on the same spindle as the rotatable magnet. A tension device (64) is provided.

Abstract: Tetrahydrothiophene derivatives of the general formula <FORM:0637924/IV (b)/1> (wherein R represents a carboxylic acyl group, R1 hydrogen or alkyl and Y-N=an arylhydrazino radical) are manufactured by reacting an arylhydrazine with an alkyl ester of a 2 - (o  - carboxybutylidene) - 3 - keto - 4 - acylamidotetrahydrothiophene, and, if desired, hydrolysing the product.  The starting materials are obtainable by the process of Specification 637,923, and the products may be further converted as described in Specification 637,925, as a step in the synthesis of biotin.  In examples, 2 - (41 - carbomethoxybutylidene) - 3 - keto - 4 - benzamidotetrahydrothiophene is refluxed in methanolic hydrochloric acid with (1) p-nitrophenylhydrazine and (2) 2 : 4-dinitrophenylhydrazine.  Other 4-acylamido derivatives, e.g. the 4-acetamido or 4-propionamido compound, and other alkyl esters, e.g. the propyl ester, may be similarly treated.  The Specification as open to inspection under Sect. 91 comprises also the manufacture of the corresponding aryl and aralkyl (e.g. benzyl) esters and of analogous compounds containing other o -carboxyalkylidene groups in place of the o -carboxybutylidene group, the manufacture of compounds in which Y-N= is a semicarbazido radical by using semicarbazide (or a salt thereof) instead of an acylhydrazine, and the subject-matter of Specification 606,192.  This subject-matter does not appear in the Specification as accepted.

Title: Adaptive braking moculator for the braking system of a vehicle

Filed: 1974-08-22
Abstract: 1435869 Brake pressure modulators BENDIX CORP 22 Aug 1974 [17 Sept 1973] 37000/74 Heading F2F Fluid pressure in a passage 32 between an inlet from a master cylinder 24 and an outlet to brakes 116 is controlled by a valve 34 controlled by a piston assembly 44 in turn actuated by an electrically actuated valve 100 to communicate pressure fluid to the assembly to close the valve 34 modulating brake pressure; the inlet and outlet are also connected by a by-pass passage 62, this passage being closed by a valve 64 responsive to the fluid pressure at the valve 100, whereby pressure failure opens the passage 62. For full braking the assembly 44, in the form of a double piston is actuated by pressure from a steering pump 28 holding a ball member 38 from a seat 36, a piston 76 being actuated by the pressure to hold a ball member 70 from a seat 66, to allow flow through the passage 32, and against a seat 68 to block the by-pass passage. If an impending skid is registered the valve 100 is operated to block pressure to the assembly 44 to cause rightward movement thereof thus blocking the passage 32 and then increasing the volume of a chamber on the left side of the assembly 44 for brake pressure decrease. Upon braking resumption, the larger right hand piston of the assembly 44 causes immediate leftward movement for passage opening. If there is a steering pump pressure failure, rightward piston movement blocks the passage 32, but similar movement of the piston 76 opens the by-pass passage 62 and closes the other end of the passage 32 for full braking. A check valve 96 stops reverse flow between a reservoir outlet 20 and a pump inlet 16 of the modulator. Diaphragms 56, 90 avoid mutual contamination of the brake and steering fluids.
