Title: Improvements in or relating to loaders
Inventor: PAUL DAVID SAMUEL
IPC: E02F3/43
Filed: 1966-08-09
Abstract: 1,138,736. Shovelling machines. MASSEYFERGUSON-PERKINS Ltd. 2 Aug., 1967 [9 Aug., 1966], No. 35519/66. Heading E1F. In a material handling machine, e.g. a shovel loader, having a boom raised and lowered by at least one hydraulic rant and a bucket or like implement pivotally mounted on the boom by a further hydraulic ram, the bucket and a control lever therefor are automatically restored to positions suitable for commencement of digging on lowering of the boom. The control lever is operatively connected to the bucket ram and a bucket reset means is mounted between the bucket and lever which is operable to move the lever automatically to a neutral position when the bucket reaches a predetermined position during movement from its dumping to its digging position. The lever is moved by a 'kick-valve' connected in a hydraulic circuit with a reset valve which is operatively connected to the bucket so that on movement of the lever to a position to move the bucket from a damping to a digging position a predetermined amount of movement of the bucket activates the reset valve which connects the 'kick-valve' to a tapping from the high pressure end of the bucket ram and so restores the lever to neutral.

Title: Improvements in or relating to the manufacture of interpolymers of styrene with polymeric fatty acid esters and coating compositions obtained therefrom
IPC: C08F212/14
Filed: 1946-12-06
Abstract: Products suitable for use in coating compositions and printing inks are obtained by interpolymerizing styrene or a nuclear alkyl or halogen substituted styrene with a partially polymerized ester produced by reacting two or more polyhydric alcohols with one or more polybasic organic acids and with an unsaturated drying oil fatty acid or a mixture of drying oil fatty acids at least one of which is unsaturated.  If desired the ester may be made in two stages by forming the partial esters of the polyhydric alcohols and either the fatty or polybasic acid and completing the esterification with the second acid or acids.  The drying oil fatty acid or mixture of acids may be obtained by saponification of a drying or semi-drying oil and the partial esters by alcoholysis of the oils with a polyhydric alcohol other than glycol.  The interpolymerization may be carried out in aqueous emulsion or in solution, specified solvents are white spirit and xylene.  The solvent may also comprise a terpene, preferably a mono-cyclic a -terpene or dipentene alone or in admixture with another solvent and if desired the terpene may be added during the reaction.  A part of the styrene, e.g. 25 per cent, may be present initially and the remainder added continuously or intermittently during the reaction.  Specified polyhydric alcohols are glycerol, pentaerythritol, mannitol and sorbitol.  Polybasic acids listed are sebacic, maleic and phthalic acids or their anhydrides. Specified fatty acids are those of linseed and tung oils, licanic acid and acids prepared by dehydration of castor oil fatty acids and the blowing of linseed oil fatty acids.  Where a mixture of drying oil fatty acids is employed it preferably comprises conjugated triene fatty acids with other unsaturated fatty acids. Specifications 573,809, 573,835, 580,912 and 609,750 are referred to.

Title: Improvements in and relating to control systems for colour lighting apparatus
IPC: H05B37/02
Filed: 1932-12-21
Abstract: 412,217. Control systems for consuming devices. HILL & SON & NORMAN & BEARD, Ltd., W., 372, York Road, Holloway, HOLOPHANE, Ltd., Elverton Street, Vincent Square, NORMAN, H. La F., 1, Lochbie, Crouch Hill, all in London, and WILLIAMS, R. G., 60, Elgar Avenue, Tolworth, Surrey. Dec. 21, 1932, No. 36212. [Class 38 (iv).] In colour lighting apparatus the illumination from each group of lamps 9, some of which have colour filters, is controlled by a separate reversible electric motor actuated dimmer which stops in an appropriate position for each colour effect, the stopping position being determined by a hunting switch in cooperation with manually operated means which determine the stopping position of the hunting switch. The contactor controlled reversible motors 4 are adapted to move the dimmer brushes 2b together with either the brushes 8, or the plates 1 carrying the conducting segments 6<i> and 6<o> and the insulating strip 7, when any one of the brushes 8 is energized in each set of apparatus. Each key 3 produces, on depression, a corresponding colour effect, energizing an appropriate brush in each hunting switch through one of the relays 8<r> or directly, the hunting switches or brush carriers and the dimmer brushes 2<b> then being moved until the energized brush 8 rests on the insulation 7. By reason of the arrangement of a spring 10 and contact fingers 11 and 12 in co-operation with each key as shown, when two keys are depressed together, only the key on the left (in the Figure) is effective. Each key when depressed is held down by friction or by a light spring and on depression momentarily energizes through contacts 14 and 13, a magnet 16 in co-operation with each of the other keys thus raising any depressed keys. Alternatively, arrangements as used in cash registers &c. may be used to prevent depression of more than one key at a time and to clock or release a depressed key when required. The main lighting circuit may be opened when required by depression of a key 3<a>. The hunting switch used may take the form of a cylinder. A modification is described (not shown) in which the brushes are arranged to co-operate with adjustable parallel conducting strips and are each supplied through a further strip or a flexible lead. An alternative dimming arrangement is described (not shown) in which the dimmers are operated through a cam arrangement by a single motor and hunting switch the switch having as many brushes as there are keys.

Title: Method of preparing attrition resistant alumina particles
IPC: B01J21/04
Filed: 1955-12-22
Abstract: Alumina particles of high attrition resistance and hardness are made by impregnating powdered aluminium trihydrate with an aqueous solution of a water-soluble salt of aluminium and a small amount of a workability agent (e.g. sodium bentonite, agar, potato or corn starch, or methyl cellulose), and working mechanically the resulting readily flowable powder until it forms a plastic dough which contains 8 to 11 per cent of water; then forming the dough into particles and drying at 220 DEG  to 300 DEG  F. to remove the free water in 10 to 60 mins.; slowly heating up to about 600 DEG  F. to form gamma alumina, and finally heating for more than 1 hour at 800 DEG  to 1700 DEG  F.  In the presence of the workability agent, the water added can be reduced to very small quantities, while preserving the property of forming a plastic dough when the impregnated alumina is subjected to mechanical milling.  For example, aluminium trihydrate powder is sprayed in a tumbling drum with a small amount of hot concentrated solution of aluminium nitrate or sodium aluminate, whereby about 1.8 parts of potential alumina is added per 100 parts of trihydrate.  At the same time 0.3 to 0.7 parts per cent by weight of methyl cellulose are added. The mixture consisting of a flowable powder is then subjected to heavy mechanical pressure for up to 5 hours in a muller, when it assumes a plastic form, which is extruded to form rods and pellets, e.g. 4.75 mm. diameter.  These are first dried at about 270 DEG  F. in heated air, and then submitted to slow drying raising the temperature at the rate of 35 DEG  F. per hour up to 600 DEG  F.  A final more rapid heating up to 1700 DEG  F. is then employed.  The product may be impregnated with chromium oxide or a platinum group metal.  Platinum, rhodium, palladium, rhodium, and osmium are specified.  If desired after the heating stage at 600 DEG F. the pellets may be leached with nitric or acetic acid to remove alkali before the final heating stage.  The impregnated catalysts may be used for dehydrogenating or hydroforming reactions. Specification 675,349 is referred to.
