Title: A method for the production of formylnitrile derivatives
IPC: C07C67/00
Filed: 1971-04-19
Abstract: 1291687 Alkali metal derivatives of α-formylnitriles; trietherified t-butyronitrile TAKEDA YAKUHIN KOGYO KK 19 April 1971 [24 Feb 1970] 22227/71 Heading C2C Compounds of the formula where R is alkyl, cycloalkyl or alkenyl and Me is an alkali metal, are prepared by contacting an alkanol and CO with ROCH 2 CH 2 CN in the presence of an alkali metal alkanolate; or by contacting acrylonitrile with an alkanol under a CO atmosphere in the presence of an alkali metal alkanolate. A solvent may be used. When R is different from the alkyl group of the alkanol or the alkali metal alkanolate, a byproduct may be obtained in which R is replaced by that alkyl group. The group =CHOMe in the product may be replaced by =CHO Alkyl by treatment with an alkylating agent (such as dimethyl or dimethyl sulphate), and the latter group is replaced by H+ -CH(OAlkyl) 2  by reaction with an alcohol in the presence of an alkali and a solvent; the two " Alkyl " groups may be the same or different.

The glasses a, bare fitted in mountings c, d which can rotate in the frame e, the mounting c being provided with a rim f by which it can be turned relatively to the mounting d. By turning the two mountings together any desired part of the field of view can be obscured.
Patent GB-781347-A (GB)
Title: Improvements relating to the removal of ash forming impurities from petroleum oil
IPC: C10G31/08
Filed: 1955-08-04
Abstract: Ash-forming impurities are removed from petroleum oils by washing the oils with an aqueous solution of an alkaline earth metal salt which solution has a specific gravity greater than that of the oil being treated.  Solutions of calcium and magnesium salts are referred to, e.g. a magnesium sulphate solution of 1.02-1.2 specific gravity. Petroleum residual fuel oils such as Bunker oils, containing calcium and sodium compounds, may be treated, to reduce the corrosivity of their ash to metal parts and render them suitable for use as gas turbine fuels; part of the magnesium salt may also be left in the oil to reduce corrosion by any remaining ash-forming impurities.  The washing treatment may be carried out at 180-200 DEG  F. and an emulsion breaker, e.g. "Tretolite" (Registered Trade Mark) may be added.  The mixture of oil and aqueous solution may be separated in a centrifuge or other separator in 2 or more stages.

Triangular members 17 support the flanges against buckling internally or externally at 23 when the shearing members are inverted as at 22. Fig. 10 shows a section of a prop having U-shaped rails 26 fitting between the flanges of the I-section lower prop 24 and the edges of the rail are sheared by two oppositely sloping cutting edges. In a further modification, Figs. 13, 14 (not shown), flat oblique opposed shearing sections are clamped between roof shaped members between the flanges of an I-section prop. In Fig. 16 the metal members 109 which are sheared by the lower edges of the upper prop part 101 are held between the two U-section irons 104 forming the lower prop part which are clamped by straps 105 and bolts 107 slotted to receive clamping wedges 108. In a modification the members 109 are of angle section. In a further modification a round wooden upper member is provided with a shoe for shearing and the lower cylindrical member is in two halves clamped together.

Abstract: 221,947. Owen, W. H. Sept. 12, 1923. Bottling; filling jars, cans, and like receptacles. -Apparatus for filling simultaneously a number of bottles, jars, boxes, tins, or like receptacles with liquid or semi-liquid comprises a moving chamber or attached group of chambers immersed in the liquid &c. so that in one position one or more apertures in the chamber register with an aperture or apertures in its casing to allow the liquid to pass into the chamber, and in another position these inlet apertures are closed, while another aperture or apertures are open to the atmosphere or air pressure to allow the liquid to pass from the chamber by an outlet aperture or apertures into the bottle &c. The supply tank is provided in the bottom with a number of orifices corresponding to the number of bottles to be filled at each operation, and contains a slidable box arranged to move to and fro over the bottom within a casing comprising two side-members connected together by springs &c. and a top member or cover. The box is divided into compartments each having an aperture a<1>, Fig. 2, in its side, an, aperture B<1> in the top, and an aperture d<1> in the bottom. The side-pieces of the casing have apertures a, Fig. 3, which register with the apertures a<1> when the box is at one end of its stroke. Two orifices B, c for each compartment are provided in the top of the casing, the aperture c being fitted with a tube communicating with the atmosphere &c. When the side orifices a, a<1> register, as shown in Fig. 5, the top orifices B, B<1> also register, and liquid parses into the compartments. At the opposite end of the stroke, Fig. 6, the bottom orifices d' of the compartments register with orifices in the bottom of the tank, and the top orifices B<1>, c also register, so that the liquid can flow into the bottles beneath the tank. A circular box divided into segments and rotating to and fro on a central point may be used instead of a rectangular box. The tank is large enough to contain several boxes which are reciprocated together by any suitable means.

Title: Improvements relating to a magnetic memory incorporating a film storage device
IPC: G11C11/15
Filed: 1966-05-23
Abstract: 1,083,065. Magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 23, 1966 [June 30, 1965], No. 22876/66. Heading H3B. [Also in Division H1] A magnetic memory element comprises two coupled anisotropic thin (1000 ) magnetic films F1, F2 (Fig. 3), arranged close together with their easy axes parallel, one film (F2) having a greater uniaxial anisotropy field than the other. The films are magnetized in opposite directions as shown, and read-out is effected by a pulse in word conductor 48 which turns the magnetic vectors of the films towards the hard direction and through unequal angles producing a stray field H s  which links with conductor 50 to provide an output. The magnetization in each film is assisted to return to its original easy axis direction by the coupling field from the other film so that read-out is non-destructive. For write-in coincident pulses are applied to bit and word conductors 50, 48, the former pulse terminating with, after a reduction of or after termination of the word pulse. Though the write-in bit pulse produces fields in the same easy axis direction in both films its effect is overpowered in F1 by the coupling field from F2 so that direction as in Fig. 3 (or opposite thereto for a " 0") are obtained. A separate sense conductor may be provided and may be disposed between the films (77A in Fig. 8A, not shown), in which case it is thin. The films may be joined at their edges to form a closed magnetic circuit (Fig. 7, not shown). Writing may be accomplished in a memory array of these devices (Fig. 9, not shown), in either a digit mode or a word mode.
