Title: Improvements in or relating to Distance Measuring Apparatus
IPC: G01S17/32
Filed: 1966-11-24
Abstract: 1,152,854. Photo-electric distance measurement. ALBISWERK ZURICH A.G. 24 Nov., 1966 [25 Nov., 1965], No. 52601/66. Heading H4D. Relates to photo-electric distance measurement wherein the phase of the amplitude modulation of an echo from the reflector is compared with that of the modulation of the wave on transmission. According to the invention the phase difference measurement is performed at a lower, e.g. audio frequency by mixing the transmitted and echo modulation signals with an oscillator 10. A simple narrow band phase measuring device 13 may be employed if the frequency of oscillator 10 is caused to follow that (F) of modulation oscillator 3 by a known means 14. Oscillator 10 may provide two frequencies at equal frequency differences one above and one below F; by switching between those two frequencies and averaging the phase measurements receiver phase distortion is eliminated.

Abstract: 1373547 Extruding; making gears; making dies REGIE RATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 18 Nov 1971 [24 Nov 1970 3 Nov 1971] 53660/71 Headings B3P and B3A  A helical gear blank is produced by cold extruding a billet 1 through a die 2 using a punch 11 which is mounted for free rotation, the die being formed with a set of helically toothed stages in which the tooth depth increases from stage to stage. Thus the billet is free to rotate to follow the teeth of the die stages. The die teeth taper in depth towards the inlet and outlet of each stage so that the extruded billet is released by each stage before entering the next stage. The billets are extruded successively and each billet pushes the preceding billet through the die. The punch is mounted by roller bearings 19-21 on a plate 15 connected to a movable crosshead 16. The die is arranged to contact the billet surface at the portion which forms the top of the gear teeth as the billet enter the die, Fig. 3 (not shown). The die, which is preferably made of tungsten carbide, may comprise three die elements 29, 30, 33, Fig. 4, clamped between rings 3, 3<SP>1</SP> and each having double tapered teeth with a neck 31. The extruded billet may have its teeth finished by rolling and be centrally bored or alternatively hollow billets may be used and the punch 11 then has a central stem. The helix pitch of the teeth can be checked by measuring the rotation of the punch for a given axial movement. The teeth are formed in the die by electroerosion followed by grinding.

A copolymer of 3 and/or 4 mono- or dialkylbicyclo - (4,2,1) mono - 3,7 - diene, ethylene and a higher alpha olefin, is prepared by polymerizing the monomers in the presence of a catalyst obtained from a vanadium compound and an organo aluminium compound or hydride, at least one halogen atom being contained within one of the catalytic components. Suitable dienes are 3-methyl-bicyclo- (4,2,1) nona-3,7-diene and 3,4-dimethyl-bicyclo - (4,2,1) - nona - 3,7 - diene. The vanadium catalyst component may be obtained from a hydrocarbon soluble vanadium compound such as a halide or oxyhalide or a compound in which at least one of the valencies of the metal is saturated by a hetero-atom (such as oxygen or nitrogen) bound to an organic group; alternatively, this component may be hydrocarbon insoluble and may be vanadyl chloride, vanadium tri-, acetate, benzoate or stearate. The polymerization may be carried out at- 10 to - 50 C., or 0 to 125 C. in the presence of a complexing agent such as an ether, thioether, tertiary amine or tri-substituted phosphine containing at least one branched alkyl group or an aromatic nucleus. The complexing agent is present in from 0À05 to 1 mol. per mol. of aluminium alkylhalide. The polymerization may be conducted in the presence of liquid monomer and in the absence of solvent, or in the presence of an inert hydrocarbon solvent. In the examples, 3,4-dimethyl- or 3-methylbicyclo - (4,2,1) - nona - 3,7 - diene, ethylene and propylene are co-polymerized in solution or in bulk using a catalyst preformed from vanadium tetrachloride and aluminium ethyl sesquichloride or vanadyl chloride and aluminium diethyl chloride, the polymerization reaction being terminated by adding phenylbeta naphthylamine in methanol, followed by purification with hydrochloric acid and water, and coagulation with acetone. The copolymer is mixed with carbon black and vulcanized.
