Patent GB-816151-A (GB)
Title: Saturated aldehydes
Inventor: LACEY RICHARD NORMAN
Filed: 1956-03-07
Abstract: Ethylenically unsaturated aldehydes are hydrogenated at elevated temperature to produce the corresponding saturated aldehydes by treating them with hydrogen in the presence of a platinum group metal catalyst prepared by a process comprising treating solid mildly alkaline supporting material with a solution of a compound of a platinum group metal in an organic solvent thereby depositing the oxide of the platinum group metal on the supporting material, treating the resulting product with an aqueous solution of the hydroxide, carbonate or bicarbonate of an alkali metal, and reducing the oxide of the platinum group metal to the corresponding metal. The supporting material on which the oxide of the platinum group metal is deposited may be a solid and substantially water-insoluble oxide, hydroxide, basic oxide, carbonate or basic carbonate of a metallic element, e.g. alumina, magnesia, titania and chromia, or, alternatively, the supporting material may be any of the materials used as catalyst supports, such as charcoal, silica gel and pumice, provided that they are mildly alkaline or are first rendered mildly alkaline by pretreating with an alkaline agent.  Magnesia and other naturally mildly alkaline materials used as supports may also be pretreated in this way.  The alkaline reagent used is preferably an aqueous solution of the hydroxide, carbonate or bicarbonate of an alkali metal such as sodium or potassium.  The pretreatment may be carried out by steeping the material in the alkaline reagent, preferably at elevated temperature.  Deposition of the oxide of the platinum group metal on the supporting material is preferably carried out by the process described in Specification 812,382, [Group III]. In this process the deposition is carried out in a medium consisting of an organic solvent largely free of water, preferably at elevated temperature.  The organic solvents, which may be used either singly or in mixtures, include primary and secondary monohydric alcohols containing up to 4 carbon atoms per molecule; ketones containing up to 5 carbon atoms; esters containing up to 4 carbon atoms; glycol ethers such as 2-ethoxyethanol and 2-butoxyethanol; water-soluble ethers such as dioxan and dihydropyran; the more water-soluble acetates; and glycols of comparatively high molecular weight such as hexylene glycol and 2-ethylhexan-1,3-diol.  The amount of water present is preferably between 1 and 15 per cent by volume.  In the example, wet crotonaldehyde is hydrogenated at elevated temperature in the presence of a catalyst obtained by treating magnesia with a solution of palladous chloride in acetone and a minor amount of water and treating the coated material with aqueous sodium carbonate solution: n-butyraldehyde is produced.  Specification 814,003, [Group III], also is referred to.

Title: Improvements in or relating to mechanisms for registering sheets being fed to printing presses or other machines
IPC: B65H9/10
Filed: 1940-05-20
Abstract: 541,333. Feeding sheets. BACKHOUSE, H. T. May 20, 1940, No. 7173. [Class 100 (i)] To assist the registration of sheets fed over a layboard to front lays one or more suction devices 4 are arranged to contact with the leading edge of the sheet as it approaches the front lays, and to move with the sheet until it reaches the lays, the suction then being cut off or in some cases maintained while the suckers 4 slide over the sheet. The face 11 of each suckar 4 is preferably inclined so that a smoothing effect on the sheet is effected as the sheet moves under the rear edge of the sucker towards the front edge. The sucker 4 is integral with a tube 9 which is reciprocated to-and-fro by an oscillating bell-crank lever 7 operated by an oscillating lever 15 actuated by a cam and Bowden wire 17. When the member 4 reaches its forward position it is raised from the sheet by the action of an abutment 21 on lever 7 upon a stop 20 on the tube 9. The air pressure in the tube 9 is controlled by a tube 12 having air connection with the hollow shaft 16 of the lever arm 15. An adjustable leak valve 14 controls the air pressure in the tube 9. The invention may be applied to overlapping feeds of the kind described in Specification 427,041.

To make a bimetal sheet or strip, low-melting point metal 2 is placed on a flat base of highmelting point metal and the two heated to a temperature between the melting points in a vacuum chamber, then, when the metal 2 solidifies the resulting ingot is removed for planing or milling and hot rolled to form a sheet or strip before further rolling, annealing, etching, cleaning and cutting. A multimetal sheet or strip may be made by casting successive layers of metal in similar fashion. For the method shown, a shallow open box 1 of steel or non-ferrous metal is made by planing and chamfering the edges of a base and welding sides to it, and bronze, copper, brass (possibly containing 3% iron) or zinc is rolled, etched and cut into pieces 2 to be placed in the box 1. An induction heater 3 in a vacuum chamber then melts the pieces 2 to form a layer bonded in the box 1 to produce the composite ingot. A graphitic cover and side wall 4 are included as susceptors.

Title: Improvements relating to power straightening machines for straightening shafts, barsand the like, applicable to other reciprocating machines
IPC: B21D3/10
Filed: 1931-03-12
Abstract: 370,157. Mechanical presses. OLDFIELD, T., 37D, Beverley Terrace, Boothtown Road, Halifax, Yorkshire. Mar. 12, 1931, No. 7574. [Class 87 (ii).] In a reciprocating machine, which may be used for straightening shafts &c., of the kind having a non-rotating reciprocating ram operated by screw mechanism through a continuously rotated worm wheel and a brake, a plain ram is loosely mounted in an externally splined screw-threaded sleeve with the nut housed either in the worm wheel or in the brake drum. The ram A is loosely mounted in a screwthreaded sleeve B, which is splined to a brake drum J, the band K of which is controlled by treadle mechanism. The sleeve engages a nut C mounted in a worm wheel D continuously rotated by a worm E. The lower end of the ram is secured by cotters &c. F to a sleeve H splined to the framing G. When the brake band is applied rotation of the sleeve is stopped whereupon the sleeve feeds through the rotating nut to effect the working stroke of the ram. In a modification, the worm wheel is splined to the threaded sleeve and the nut carried by the brake drum, in which case on applying the brake the sleeve screws through the fixed nut to effect the working stroke of the ram. The brake band is prevented from shifting on the drum by securing it to a bracket R pivoted at S to a bracket on the framing.

Title: Method and devices for indicating groups of characters on the screen of a cathode-ray-tube
Inventor: EBERT GUNTER
IPC: G09G5/24
Filed: 1969-02-12
Abstract: 1,263,524. Cathode-ray tube displays. ELEKTRONISCHE RECHENMASCHINEN-WISSENSCHAFTLICHER INDUSTRIEBETRIEB-KARL-MARX-STADT VEB. 12 Feb., 1969, No. 7624/69. Heading H4T. In a cathode-ray tube display arrangement in which characters are produced on the screen in dot-matrix form by means of "bright-up" pulses derived from a character matrix the latter is "interrogated" in a cyclic manner and in such a sequence that one (store) location in the matrix which is not involved in the particular character reproduction is interrogated last in the cycle and during this interrogation the other (store) locations are "set" in the configuration appropriate to a fresh character and the tube beam is moved to the position at which such character is to be displayed. Fig. 1 shows the character matrix Z through all the cores of which a "write" line E (Fig. 2) is threaded and through selected cores of which a plurality of character lines are threaded in a configuration determined by the particular character. The latter are determined by fourbit codes derived from a cyclic store U and supplied via a register A to a decoder D which operates to select via switches S A  the character line apertaining to the particular character. In operation a current Im/2 is caused to flow in the write line E and a current of similar magnitude is produced in the selected character line. The effect of these two currents (= Im) is to place the cores of the selected character lines in the set ("1") state. The matrix is then "interrogated" by means of shift register V<SP>1</SP>, H<SP>1</SP>, operating as ring counters, the interrogation being effected in cyclic manner such that the cores are re-set (to cause an output pulse in a sense wire for bright up of the beam of the display tube) in the sequence shown from 1 to 35. In the example shown, core 35, which is not involved in the particular character reproduction, is the last to be re-set and the outputs from the stages of the registers which effect this produce respective pulses Py, Px which are supplied via an AND gate G to cause the next character to be selected and to cause the tube beam to be stepped on to the position for display of the next character via a positioning device P (e.g. a staircase waveform generator). Since the cores appertaining to the next character are "set" whilst the last core is being interrogated the currents in the row and column containing the last core are compensated by retreading the write line back through the cores of such row and column in the same direction.

Title: Cyclopentanopolyhydrophenanthrene compounds
IPC: C07J9/00
Filed: 1952-08-01
Abstract: The invention comprises the unsaturated hydroxy substituted cyclopentanophenanthrene compound obtained by reacting osmium tetroxide with a cyclopentano-phenanthrene compound having at rings B and C the formula <FORM:0768646/IV(b)/1> and subjecting the resulting osmate ester to alkaline hydrolysis, and the above process for the preparation thereof.  The exact structure of the above hydroxy substituted cyclopentanophenanthrene compound is not known, but the compound is probably a cyclopentanophenanthrene compound having at rings B and C the formula <FORM:0768646/IV(b)/2> <FORM:0768646/IV(b)/3> or may be a mixture of compounds having both formul .  The preferred reactants for the above process have at the 3-position a 3-acyloxy group which is hydrolysed by the process, and at the 17-position a sterol side-chain such as ergosterol, a bile acid side chain such as cholanic acid, a degraded bile acid side chain such as bisnorcholanic acid, a pregnane side chain (-COCH3), or a sapogenin side chain such as tigogenin.  The hydrolysis of the osmate ester may be carried out by treatment with sodium sulphite, sodium bicarbonate or an aqueous alkaline solution of mannitol.  The invention also includes the acyl derivatives of the above hydroxy compounds where the acyl group contains not more than 6 carbon atoms, and these derivatives may be obtained by the incomplete hydrolysis of the osmate ester intermediate, or by partial or complete acylation of the hydroxy compounds.  In the examples: (1) a trihydroxy cyclopentanophenanthrene compound believed to be a mixture of 3,9,11-trihydroxy-D 7(8),22-ergostadiene and 3,7,8-trihydroxy-D 9(11),22-ergostadiene is prepared from ergosteryl D acetate, and the product is diacetylated to form a diacetoxy derivative believed to be a mixture of the corresponding 3,11-diacetoxy and 3,7-diacetoxy compounds which may be hydrolysed back to the original trihydroxy compound; (2) ergosteryl D acetate is reacted with osmium tetroxide, and the osmate ester thus produced is hydrolysed to form a product believed to be a mixture of 3-acetoxy-9,11-dihydroxy - D 7(8),22 - ergostadiene, 3 - acetoxy-7,8 - dihydroxy - D 9(11),22 - ergostadiene and the corresponding 3,9,11- and 3,7,8-trihydroxy compounds; the mixture may be subjected to chromatography to separate the acetoxy compounds from the trihydroxy compounds, and the trihydroxy substituted product may then be diacetylated as in (1).
