Title: Improvements in and relating to apparatus for testing the lubricating properties andvalues of oils
IPC: G01N33/30
Filed: 1931-10-06
Abstract: 389,163. Testing lubricating- efficiency of liquids. VIGZOL OIL REFINING CO. (LONDON), Ltd. and BILTON, P., 14, Eastney Street, Greenwich, London. Oct. 6, 1931, No. 27703. [Class 106 (ii).] Comprises apparatus for testing oils by means of the inertia of a rotating member mounted on a lubricated surface of a further rotatable member to which it is coupled till rotated at a desired speed and thereafter is allowed to rotate freely, means being provided to indicate or register the extent of such rotation. A hollow shaft 12 mounted in bearings 10, 11 is driven by belt and pulley gear from a motor 5 through a lay shaft 7. The shaft 12 at one end extends into the boss 16 of a momentum device comprising the boss 16 provided with radial arms 17 ending in balls 18. The boss is provided with a liner forming a bearing surface which is loose on a bearing surface on a sleeve screwed on to the shaft 12. An inner shaft, 31 attached to a cup 28, which in turn is fastened to the boss by a dowel pin, passes through a ball bearing in the end of the shaft 12 and extends through the shaft 12 to be coupled by a clutch 34, 35 to the driving shaft of a revolution counter 13. The boss 16 may be clutched to the shaft 12 by a friction clutch 24, 25. In use, the oil to be tested is admitted to the boss 16, the clutch 24, 25 being thrown in by a counterclockwise movement of the handle 38, which movement releases the clutch 34, 35 and a brake 39 acting on the face of the pulley 9 and the motor is started. When, the speedometer 40 indicates a desired speed, the clutch 24, 25 is thrown out and the counter 13 clutched to the shaft 31, the brake 39 also being applied. The number of free revolutions of the momentum device is then counted and this is a measure of the lubricating value of the oil. The momentum device may then be disconnected and cleaned for use with another oil to be tested.

Title: Improvements in or relating to the concentration of ethylbenzene
IPC: C07C7/148
Filed: 1945-10-22
Abstract: Ethylbenzene is separated from, or concentrated in, hydrocarbon mixtures comprising ethylbenzene and a xylene by reacting said xylene with di-(alphachlorethyl) ether at -15 DEG  C. to +15 DEG  C. in presence of zinc chloride while limiting the water content of the mixture throughout the reaction to a value not exceeding 50 per cent by weight of the zinc chloride, and subjecting the mixture to fractional distillation.  The reaction may be carried out by passing hydrogen chloride into a mixture of acetaldehyde, zinc chloride, and the hydrocarbon mixture, thus forming the ether in situ, or hydrogen chloride may be passed into a solution of acetaldehyde in the hydrocarbon mixture, the water layer formed being separated, and zinc chloride added to the other layer.  Paraldehyde, or other substances yielding acetaldehyde, may replace the acetaldehyde.  An example describes the reaction of a mixture of ethylbenzene and m-xylene with zinc chloride, hydrogen chloride and paraldehyde, the aqueous layer being separated, and the other layer fractionally distilled. Specification 603,498 is referred to.

Filed: 1922-10-14
Abstract: 202,257. Monteath Photo Sculpture, Ltd., (Assignees of Monteath, F. H.). Aug. 10, 1922, [Convention date]. Embossed and relief photographs; bichromated colloid processes.-A process for producing plaque bas-reliefs, embossing dies, &c. comprises (1) producing a negative of the subject using frontal lighting and a black background, (2) producing on a glass or like support a plate of bichromated gelatine, one-eighth of an inch thick, in a warmed vertical mould, (3) printing from the negative through a mask on to the gelatine plate in daylight for two hours, (4) masking the printed portion and printing the surround through clear glass for ten minutes, and (5) developing the plate in water to produce by swelling a relief from which a plaster or like cast can be taken. In preparing the bichromated gelatine, the bichromate is added in dry powdered condition to gelatine, which has been soaked in cold water, drained free from surplus water, and melted by heat, the proportions employed being 5 grains of bichromate to 1 dram of dry gelatine. The mould in which the gelatine plate is cast comprises a glass or like backing- plate A and a flexible polished sheet of tinned steel or copper B backed by a glass or like plate C, the whole being held together along three edges by a rubber rebated frame D and on the fourth edge by a rubber parting strip G so as to leave a chamber between the plates A and B about oneeighth of an inch thick. The plates are securely held by a number of clips such as that shown at N. The mould is heated to the same temperature as the melted bichromated gelatine, and this is siphoned or poured through a flooded funnel into the mould through the aperture H or K. The temperature is maintained until the gelatine is clear and free from bubbles. The mould is then cooled and dismantled, and the plate B is stripped from the gelatine sheet; which remains on the plate C during the subsequent operations. The cast ultimately taken in plaster, wax, &c, may be bronzed, electroplated, &c. to yield any desired finished effect, or may be used as a matrix for producing repetitions in known manner, or for producing embossing dies and founder's patterns.

Abstract: 1494010 Reversal processing photo-sensitive silver halide colour material EASTMAN KODAK CO 3 July 1975 [10 July 1974] 28093/75 Heading G2C An imagewise exposed photographic material comprising a support bearing at least one photosensitive silver halide emulsion layer and contained therein or in one or more adjacent layers a non- diffusible primary aromatic amino silver halide colour developing agent and a non-diffusible colour coupler is (1) treated with an alkaline non-cross-oxidizing silver halide developer composition (which comprises a black-and-white developing agent which becomes oxidized when it develops exposed silver halide to silver and will not oxidize the colour developing agent) to produce a silver image, (2) fogged, (3) treated with an alkaline cross-oxidizing silver halide developer composition (which comprises a black-and-white developing agent which becomes oxidized when it develops exposed silver halide to silver and crossoxidizes the colour developing agent) to produce both silver and dye in the fogged areas; (4) bleaching the developed silver with a bleach solution having an oxidation potential such that it will not oxidize any remaining colour developing agent and (5) fixing. The non-cross-oxidizing developing agent may be ascorbic acid or a 5-amino- or 5-hydroxypyrimidine e.g. 2-methyl-4-amino-5, 6-dihydroxypyrimidine.

In walking mechanism for a soil working implement comprising support skids 3 attached to a frame (not shown), two walking skids 4 arranged on opposite sides of the frame outwardly of the support skids 3, and cross beams 7 slidably mounted transversely of the support skids 3, the cross beams 7 are arranged in pairs with the laterally outer ends of the cross beams of each pair attached to respective ones of the walking skids 4. Each cross beam 7 is slidably mounted in a box-shaped guide 6 and is displaceable therein by means of a respective one of hydraulic rams 20. Control means for the rams 20 is arranged so that the cross beams 7 of a pair are displaceable either both in a selected direction or in respective opposite directions, and so that those cross beams 7 of both pairs that are connected to one walking skid 4 are displaceable either both in a selected direction or in respective opposite directions. This provides for reduction of the distance between the skids 4 to a minimum for transportation purposes and for increasing the distance to obtain maximum stability, and enables the implement to step sideways and excute rotary movements. As described in the main patent, the mechanism comprises lifting cylinders 8, stirrups 11 carrying rollers 13, rails 12 attached to the walking skids 4, and displacing cylinders 16. More than four cross beams may be provided, either arranged in more than two pairs or in groups of more than two.
