Title: Improvements in alignment gauges for the wheels of vehicles
IPC: E01B35/02
Filed: 1932-03-18
Abstract: 394,090. Linear-dimension gauges. SIMMONDS, J. E. and PETERSON, C., 26, Hatton Wall, London. March 18, 1932, No. 8095. [Class 106 (ii).] An alignment gauge for vehicle wheels comprises a main tube 1 having a telescopic member 4 pressed outwards by spring pressure, a longitudinal slot 2 in the main tube, a fixed indicator or scale 3 adjacent the slot and acting in conjunction with a pointer, and pins or studs 7, 7a at the ends of the device for engagement against the inside of the wheels or tyres. The slot 2 extends a little way from one end of the tube 1 and in the other end are formed a series of holes 1a in line. On the outer end of the tube 4 is fixed a bracket 6 carrying a pin or stud 7 parallel to but eccentric to the tube 4. In a modification, the bracket is slotted and the pin adjustable therein. In the tube 4 is a longitudinal slot 9 in which a pointer 10a is guided. When the tube 4 is pushed in the slot 9 coincides with the slot 2 and the pointer 10a can be slid along the main slot 2. The tubes cannot rotate relatively and a stop prevents the tube 4 moving out of the main tube. The other end of the main tube is provided with an open-ended tube 11 having a spring- pressed stud 12 to engage any of the holes 1a, and in this tube are formed a line of holes 11a into any of which a spring stud 13a on an inner rod or tube 13 takes. To the end of this inner tube 13 is secured a bracket 6a and stud 7a. To use the device, the spring pins 12, 13a are adjusted so that the device is longer than the distance between the tyres and the tube 4 is pushed in until the studs 7, 7a abut against the inside walls of the tyres with the ends of the depending chains 8, 8a just touching the ground. The pointer 10a is then moved to register with the arm 3a. The wheels are then moved forward to allow the device to engage the rear of the wheels when the pointer indicates the amount of " Toe in " or " Toe out."

Title: Improvements in or relating to the production of food
IPC: A23J1/00
Filed: 1940-05-08
Abstract: Protein is obtained from grass, herbage and other leaves by comminuting the material, separating the sap and precipitating the protein therein by heating, adding acid, or adding an alkaline substance.  In the first two cases, the precipitated protein is then washed with an alkaline solution to improve the taste, and this washing may also be used in the last case.  The product is green, but the colour may be removed by extraction with a solvent such as acetone; on evaporation of the solvent, the residue, containing chlorophyll and carotenoids, may be used as a source of vitamins or as an ingredient in balanced rations.  The precipitated protein decolorized or not, may be fermented anaerobically to produce a cheese-like product as described in Specification 511,525, [Group VI], and the mother-liquor, owing to its content of sugar, nitrogen and mineral matter may be used as a substrate for the growth of yeast.  Examples describe the extraction of protein from grass sap. When hydrochloric acid is the precipitant, the washing is effected with sodium bicarbonate solution.ALSO:Protein is obtained from grass, herbage and other leaves by comminuting the material, separating the sap and precipitating the protein therein by heating or by adding an acid or an alkali, the precipitated protein being then washed with an alkaline solution to improve the taste.

Title: Process for the manufacture of metallic iron for use as a pharmaceutical preparation
IPC: A61K33/26
Filed: 1937-04-12
Abstract: Metallic iron powder for medical use is rendered more readily soluble in the gastric juices by bringing the particles into permanent contact with small proportions of platinum ruthenium, osmium, iridium or rhodium by depositing such metal by reduction on the metallic iron powder, or by reducing a compound of the metal simultaneously with a compound of iron.  The specified metals have a lower hydrogen over-voltage than that of iron so that polarization by the hydrogen evolved on solution is reduced, and the iron dissolves more quickly and completely.  The second metal is used in proportions of 0,1 to 1 per cent and is insufficient to form a complete coating on the iron particles. The powder may be made up in the form of tablets by coating with digestible material such as chocolate and malt, or doses of the powder may be provided with an air- and water-tight coating of an alcoholic solution of vegetable resins.  According to examples: (1) reduced iron powder is added to an aqueous solution of platinic chloride, through which carbonic acid is passed, so that the platinium is deposited on the iron; (2) an acid solution of ferrous sulphate is mixed with a solution of platinum chloride, caustic soda is added, and the precipitate obtained is washed, dried, pulverized and reduced by heating in a current of hydrogen. Specification 386,499, [Group II], is referred to.ALSO:Metallic iron powder for medical use is rendered more readily soluble in the gastric juices by bringing the particles into permanent contact with small proportions of platinum, ruthenium, osmium, iridium or rhodium by depositing such metal by reduction on the metallic iron powder, or by reducing a compound of the metal simultaneously with a compound of iron.

Title: Alkyl and cycloalkyl hydroperoxides
Inventor: GRAY JOHN ALAN
IPC: C07C409/04
Filed: 1951-04-13
Abstract: Alkyl and cycloalkyl hydroperoxides are obtained by exposing to ultraviolet light a gaseous mixture containing oxygen, a volatile paraffin or cycloparaffin, and a metallic vapour photosensitizer capable of absorbing ultraviolet light and composed of the same metal as that used in the source of ultraviolet light, and then condensing out the hydroperoxide so obtained.  Any paraffin or cycloparaffin which is a gas or which is a liquid able to exert a significant vapour pressure at the preferred temperature of about 40 DEG  C., e.g. a paraffin containing from 1 to 10 carbon atoms or a cycloparaffin containing 3 to 10 carbon atoms, may be used and the mixture with oxygen can contain inert materials such as nitrogen.  It is preferred to use 1 to 100 volumes, e.g. 5 to 20 volumes, of paraffin per volume of oxygen.  The photo-sensitizer used is a metallic vapour such as mercury, zinc or cadmium and it is desirable to use as much sensitizer as can conveniently be kept in the vapour phase under the conditions used.  The temperature should not be above that at which the desired hydroperoxide is stable and is preferably between 10 and 80 DEG  C. The reaction may be carried out batchwise but is preferably carried out by passing the gas mixture through the reaction space continuously.  The hydroperoxide is separated from the mixture by condensation generally at below 0 DEG  C. and the remainder of the gas mixture can be recycled, if necessary after re-saturating with sensitizer.  The products may be used as catalysts in vinyl polymerization processes.  In an example a mixture of ethane and oxygen in the volume ratio 9 : 1 and at atmospheric pressure is saturated with mercury vapour at 40 DEG  C. and passed through a quartz reaction vessel illuminated with light of wavelength 2537 from a low-pressure mercury arc.  The residence time in the illuminated zone is 10 seconds and the exit gas is cooled in a vapour trap to -80 DEG  C. where ethyl hydroperoxide and mercury are collected, the uncondensed gases being recycled and the hydroperoxide distilled from the residual mercury.  Other hydrocarbons specified are methane, propane, butane and cyclohexane.  Specification 574,958 is referred to.

Title: Automatic electric circuit breakers
Inventor: COLE THOMAS MITCHELL
IPC: H01H71/52
Filed: 1953-03-31
Abstract: 737,604. Automatic circuit-breakers; switches held set and freed mechanically. FEDERAL ELECTRIC PRODUCTS CO. March 31, 1953, No. 8868/53. Class 38 (5). A circuit-breaker comprises a uni-planar member 66 pivoted at 72 and having a contact 32 engageable with a fixed contact 30. An actuating lever 88 pivotally mounted on the member 66 is connected by a resilient link 108 to the operating handle 64, a latch extension 86 of the lever 88 normally abutting the end of a bimetal strip 84 fixed at its other end to the member 66 and connected by a conductor 126 to a plug-in terminal 24. The handle 64 forms with the link 108 an overset toggle, the lever 88 being normally held against clockwise movement by its engagement with the strip 84 whereby a compression spring 110 acting between the handle and the member 66 is normally unable to open the contacts 30, 32. On overload the strip 84 deflects due to the current therein and disengages the extension 86 permitting lever 88 to pivot and unlock the toggle 64, 108 and the spring 110 opens the contacts 30, 32 and also moves the handle to the " off " position. On cooling of the strip 84 the circuit-breaker may be reclosed by the handle 64. The contacts may also be manually operated " off " and " on " by the handle 64, in which instance the parts 84, 86 remain in engagement. To prevent current by-passing the strip 84 and flowing to the contact 32 through the lever 88 and member 66, the member 66 may have a high resistance part 68 and a low resistance part 70. Alternatively, the lever 88 may be of high resistance material. Also, the lever 88 may pivot on an insulating bush provided on the member 66 (Fig. 7, not shown). The strip 84 may also be deflected on overload by the attraction of a magnetic member 160 thereon towards a rigid armature 162 carried by the member 66. The insulating circuit-breaker casing 10 is in two parts having co-operating portions which define an arcing chamber 28 and is provided with a recess 18 and re-entrant portion 20 for mounting on a board as disclosed in Specification 737,603.
