Title: Improvements in or relating to cathode-ray devices
Inventor: SCHAGEN PIETER
IPC: H04N9/22
Filed: 1957-09-27
Abstract: 880,477. Cathode-ray tubes. MULLARD Ltd. July 21, 1958 [Sept. 27, 1957] No. 30375/57. Class 39 (1) A cathode-ray device comprises an elongated beam trajectory control space extending to an elongated luminescent target surface which is defined by motion of a rectilinear generatrix maintained parallel to a longitudinal datum line. An electron beam is directed into the control space from an end region thereof in an initial trajectory plane which intersects the target longitudinally and a control field F having a configuration orthogonal to this plane in the region thereof is set up in the control space to bend the path of the beam towards the target. The point of impact of the beam on the target is scanned longitudinally by varying the angle of entry of the beam into the control space and a variable deflection of the beam in a direction transverse to the initial trajectory plane is effected by a deflecting field having a non-uniform configuration such that, for a given deflection power, its deflecting action varies in dependence upon the angle of entry of the beam so as to counteract trapezium or analogous distortions. The control field F may be an electric field as described in Specification 865,663 or a magnetic field as described in Specification 865,666. The target Tg may comprise three longitudinal parallel luminescent strips each adapted to luminesce in a different primary colour. The formation of 3-coloured traces may be produced by high-frequency spot wobble action which may be sinusoidal or of a sawtooth nature to permit the beam to dwell for equal periods on each colour strip in a sequence. The transverse deflection means may be a coil 4 used alone or with an additional coil 4A having a smaller diameter or fewer ampere-turns than coil 4. The electrostatic deflection plates D may be replaced by a pair of saddle-type coils in a conventional permeable yoke having eight inwardly-directed teeth, while coil 4 may be of square outline bent into saddle-shape and coil 4A may be a plane circular coil, Fig. 7 (not shown). Specifications 827,851, 846,544 and 865,665 also are referred to

Patent GB-197906-A (GB)
Title: Measuring machines such as fabric measuring and cost computing machines
IPC: G01B5/04
Filed: 1922-11-07
Abstract: 197,906. Wheeler, J. L. May 19, 1922, [Convention date]. Measuring.-To prevent the measuring-roller from rotating after the fabric to be measured has passed over it, measuring-machines are provided with an anti-spinning device comprising a detent-wheel rotating with the measuring-roller and having a pawl which is controlled by a member supported by the fabric and is adapted, when unsupported, to engage the detent-wheel to stop the measuring-roller. The invention may be applied to measuring-machines having charts which are moved by the length-indicating mechanism in alignment with scales showing the price per yard. In the form shown in Fig. 3, the fabric 9<a> passes between the measuring-roller 8 and a movable presser roller 10 and supports a pivoted member 24 connected to a cam-piece 30. A face 32 on the cam-piece thus allows a detentpawl 21 to fall clear of a detent-wheel 20 on the measuring-roller and to be supported against a stop 23. When the end of the fabric has passed through the machine, the cam-piece 30 falls and turns the detent into position for stopping the roller 8, a stop 34 limiting the movement of the pawl. When fabric is inserted into the machine, a lever 17 for cutting and marking the edge of the fabric is depressed and engages a projection 19 on the lever supporting the presser roller 10. The roller 10 then engages an extension on the cam-piece 30 to raise it together with the member 24, and an arm 37 of a bell-crank lever the other arm 38 of which moves the pawl clear of the detent-wheel. In a modification, the pawl 39, Fig. 5, is so designed as to fall by gravity into a position clear of the detent-wheel 44, and the bell-crank lever is dispensed with, the other parts being similar to those shown in Fig. 3. Specification 197,907 is referred to.

Title: Preparation of acyclic terpene diols and derivatives thereof
IPC: C07C33/035
Filed: 1959-09-10
Abstract: Acyclic terpene diols, specifically 2,6-dimethyl-7-octene-2,6-diol, and 2,6-dimethyl-6-octene-2,8-diol, are prepared by the aqueous hydrolysis of myrcene dihydrochloride or dihydrobromide, wherein the aqueous medium is maintained substantially neutral.  The hydrohalide liberated is neutralised by adding for example carboxylic acid salts of alkali metals, and alkali and alkaline earth hydroxides, carbonates and bicarbonates preferably a substantially insoluble base such as calcium carbonate, is used in excess.  The myrcene dihydrochloride may be prepared by treating pyrolysed b -pinene with hydrogen halide, and catalysts such as cuprous halide may be employed.  The hydrolysis which may be at between 25 and 100 DEG C., yields a mixture of the two diols which may be separated by fractional distillations or crystallisation.  Aldehydes may be prepared from the diols by treating with chromic acid to produce hydroxy-dihydrocitral, or copper chromite to produce hydroxy-dihydrocitral, hydroxy-dihydro-citronellal.  Examples describe the preparation of 2-hydroxy-dihydro-linalool; dehydration to a -ocimene and 2,6-dimethyl octane; acetylation to the diacetate and a -geramyl acetate; and purification, and the isomerisation and separation of 2-hydroxy geraniol.  Treatment of the products is also exemplified viz. the oxidation with chromic acid type oxidants to hydroxy-dihydrocitral, followed by dehydration to citral or condensation with acetone to hydroxy-dihydro pseudoione; isomerisation to hydroxy dihydro geraniol with formic acid; hydrogenation to hydroxy dihydro-citronellol followed by dehydration to citronellol; and conversion to hydroxy-citronellol by heating with copper chromite.
