Title: Agglomeration process and apparatus
IPC: A23P10/22
Filed: 1966-12-06
Abstract: Pulverulent products such as foodstuffs and dietetic products e.g. milk powders, chocolate flavoured beverages and soups, are brought into contact with at least one jet of liquid with an initial velocity of at least 8 metres per second and a temperature of at most 30 DEG C., the product is moistened and carried along by the jet so that the particles are agglomerated, and the product is collected and dried in the form of a powder of agglomerated particles.  Water, optionally containing to some extent at least substances to be included in the composition of the pulverulent product, or an aqueous solution or dispersion of the pulverulent product is projected under a pressure of at least 10 kg/cm2 and at a temperature of between 5 DEG  and 15 DEG C. through one or more nozzles directed horizontally or inclined obliquely upwards and giving a flat jet of liquid in the shape of a fan at its origin.  The pulverulent particles are uniformly delivered from a vibrating feed assembly into contact with the jet of liquid in a quantity sufficient for all the liquid to be absorbed by the particles in a few seconds and the agglomerated particles are dried while suspended above a vibrated screen by air at a temperature of not more than 100 DEG C.  Damp air is exhausted from the assembly and fine particules are collected for recycling. An Example is directed to the agglomeration of skim milk powder with the aid of jets of a 10% dispersion of skim milk powder in water.

Abstract: 1371220 Compressed air starting of internal combustion engines SOC D'ETUDES DE MACHINES THERMIQUES 30 Nov 1971 55423/71 Heading F1K A starting distributor 1 is mounted on the frame or crank-case 2 of a diesel engine, for example a six cylinder engine, and is arranged coaxially with the engine cam-shaft. The camshaft has an extension 7 for driving auxiliaries. The end of the shaft 7 is connected by a coupling 8 to a drive shaft 9 in the distributor 1. As the outer diameter of the distributor disc 16 is greater than the outer diameter of the cylindrical portion 20,of the rotor, the compressed air which enters through the opening 24 tends to push the disc 16 against the body 3. To reduce friction the face 17 of the disc 16 can be lined with a material having a low friction coefficient. When the disc 16 is in the position shown in Fig. 1 the opening 38 is in register with an opening 32 in the body 3 so that the compressed air arriving through the annular space 23 in the housing 13 passes through the latter and the passage 30 and the opening 31 to feed one engine cylinder. The other cylinders are exhausted through the other openings 31 and passages 30 whose openings 32 are in register with the groove 41. The recesses 42 are in register with the circular exhaust channel 44 of the body 3. In a modification (not shown) the air inlet is coaxial with the distributor shaft.

Abstract: 1,220,575. Laminates. BRITISH IRON & STEEL RESEARCH ASSOCIATION. 12 March, 1968 [13 Dec., 1966], No. 55714/66. Heading B5N. A laminate comprises a core sandwiched between a pair of metal skins, the core being either a non-porous material having a specific gravity in the range 0À5 to 2À0 inclusive, or a porous, expanded or fibrous material having an apparent specific gravity in the range 0À1 to 2À0 inclusive, or a combination of such materials. The laminate has a thickness in the range 0À010 to 0À120 inch inclusive, and the core has a thickness not greater than 50% of the laminate thickness and not smaller than a percentage of the latter thickness such that the laminate has a vibration damping factor at least ten times as great as that of a solid sheet of the same thickness as the laminate of the metal which forms the skins or, where the skins are of different metals, of that metal which has the higher vibration damping factor. Either the core is held against the skins by mechanical fastening means, or is secured thereto by an adhesive, or itself forms the adhesive and is of P.V.C., polypropylene, or a thermoplastic adhesive having an acrylonitrile rubber base. The metal skins may be of the same or different metals, and of the same or different thicknesses. They may be of tinplate, cold rolled steel, stainless steel, or aluminium, and may be coated, embossed, or chemically treated. The core when non- porous may be of unplasticized P.V.C. polypropylene, a thermosetting resin blended with natural or synthetic rubbers or elastomers, polythene, polystyrene, cellulose acetate or cellulose based film. The core when porous may be of wood-based or asbestos paper, a woven fabric of polypropylene, polyester, nylon, cellulose acetate, jute, sisal, cotton, silk or glass fibres, resin impregnated paper or wood. Combinations of one or more of the fabrics with one or more of the non-porous materials may be used. The core or skins may be perforated or expanded. The laminate may be formed by the laminµ being held to each other by mechanical fastening at suitable points. Alternatively the skins and/or core are roller coated with a thermoplastic acrylonitrile rubber base adhesive and the layers joined under pressure, possibly using heat. In another method the skins are coated with the above adhesive and joined so that the adhesive forms the core material, or the metal skins are each roller, spray, or dip coated with the core material and joined by pressure possibly with heat. If the core material is polypropylene or P.V.C. the skins are bonded directly to the core under heat and pressure. Alternatively an adhesive-coated plastics core, of which the adhesive is precured by passage through an oven, is fed as a web between two steel webs, the assembly is laminated between pressure rolls, quenched and coiled. The laminates are heat and sound insulating, and vibration damping and may be used in office furniture, domestic appliances, vehicle body panels, or curtain walling.

Filed: 1967-12-12
Abstract: 1,206,460. Percussion tools. Z. MORISHITA, and S. KAWATA. 12 Dec., 1967, No. 56504/67. Heading B4C. [Also in Divisions B3 and F2] A cam operated drop and spring type percursive tool comprises a hammer piston 8 with a laterally extending roller 29 which coacts with a cam 24 rotated via shaft 23 by a primemover, e.g. an electric, oil pressure or compressed air motor. The slot 26 through which the roller protrudes may be parallel or inclined with respect to the axis of the piston. The piston is mounted in a tubular housing 1 to which an oil tank 2 and a tool bit holder 15 are connected. In operation, vibration in the tool causes valve member 4 which is biased by a compression spring into aperture 3 to be displaced to permit oil to pass into the housing. Steel balls 11 carried by the piston are lubricated by the oil. The oil also lubricates the shank of the tool bit 13, and forms a film between washers 14 to assist in absorbing the force of the piston. Relative rotation between the housing and the holder and oil tank is prevented by springs 20. The shaft 36 of the motor has a tapered end which is in frictional engagement with a coupling plate 37. The plate 37 has pins received in rubber bushes in holes in coupling plate 38. The lower end of the cam shaft is supported by a steel ball 34 contacting a convex piece of stone. In an alternative embodiment (Fig. 8), the lower end of the cam-shaft 23 has a gearwheel 49 which engages with an annular gear 48 connected to the tool bit holder 43, 46 which is adapted to rotate relative to the housing. The tool bit has a hexagonal portion received in a corresponding aperture in the holder. The tool bit includes a detachable tip 50 frictionally engaged in a tapered recess. The tip can be released by inserting a tool through an aperture 51, and additionally or alternatively by aid of nut 52. The motor may be connected to the cam-shaft by a flexible shaft.

Abstract: 1411647 Antiskid braking systems for tractor-trailer combinations TELDIX GmbH 6 Dec 1973 [21 Dec 1972] 56658/73 Heading F2F An antiskid control system for the brakes of a tractor of a tractor-trailer system in which the tractor can be connected electrically to the trailer includes a recognition logic circuit in the tractor and two signal generators in the trailer are supplying to the logic circuit a first signal representing electrical connection of the trailer to the tractor and the other supplying a second signal representing the presence of an antiskid control system in the trailer, the logic circuit producing a switching signal, with the presence of the first signal and absence of the second signal, to switch off or modify the action of the antiskid control of the tractor to prevent a strong deceleration which, when there is no trailer brake controller or it is defective, can lead to jack-knifing of the combination. The tractor has wheel sensors 1, 2 for non driven wheels and a sensor 3 for the driven wheels providing pulses which are converted into voltages proportional to wheel speed by converters 4, 5, 6. Stores 7, 8 help to provide voltage, approximately corresponding to vehicle speed, which is converted in elements 10, 11 to reference threshold values which are compared in elements 12, 13, 14 with wheel speeds to determine slip and produce signals via circuit 15 to modifying braking, e.g. by means of valves. The trailer has an antiskid controller 20 fed by sensors 21, 22 and element 10 feeds in a reference value via a plug 23. The recognition logic unit comprises transistor switches 31, 32 and an AND gate 33. If no trailer is coupled plug 23 and a standard plug 25, for lighting &c., are not connected, the AND gate provides no signal. If the trailer has no antiskid controller or plug 23 is uncoupled in error or the controller is faulty a switch signal appears to modify the tractor controller but presence of both signals provides no switching output.

[Also in Division G5] A device for use in the management of animal reproduction comprises a board 1 having markings thereon representing reproduction details a particular kind of animal, e.g. cows or pigs, and a transparent disc 2 pivoted at 3 to the board 1 and having peripheral markings 6 thereon representing days and months of the year, a marker 4 for each cow of the herd(s) being adhesively (but removably) attached to the disc 2 in positions indicative of the condition of the cow. Today's date (as seen on markings 6) is maintained always on the datum line 8 on the board 1, i.e. by rotating the disc 2 by one day marking every day. On the day when a particular cow calves, its marker 4 is adhered to the disc 2 so as to overlie the part 21 of the line 8, then as soon as heat is observed, the marker is moved radially outwards until it overlies one of the lines 10 (each defining a 21-day oestral cycle) where it is adhered. (If heat is not observed by two months after calving, the wet is called.) The cow is served after three such 21-day cycles and the marker 4 is placed on the disc 2 to overlie the line 11 on the board 1. When the marker 4 crorsses the line 13 on the board 1, the cow is observed for oestrus; if signs of oestrus are observed the cow is served again and the marker 4 is placed to overlie the "first return" part of the line 11 (&c); if no signs are observed, the marker 4 is not moved but as it crosses the line 15, the vet is called for pregnancy diagnosis. If the cow is confirmed in calf, the marker 4 is placed to overlie the part 23 of the line 15. The cow is dried off as the marker 4 reaches the line 16, concentrates are started at line 17, followed by steaming up and then calving at line 8. The markers 4 may each carry only the cow number, or the numbers or faces of the markers may be coloured to denote different herds. New heifers (or the bull used) may be represented by a differently coloured marker.

The signals S 1 -S n  are derived from reading photocells in each remote station and the leading edge of a pulse in a signal S i  shows when a card leaves a station, and the trailing edge, when the following card reaches the same station. It is desired that signals S 1 -S n  have a particular timed relationship at each remote unit, and hence the C.R.T. display takes the form of parallel rows of vertical or horizontal dashes, each row corresponding to a signal S i  or To and each column occurring at a particular strobe pulse, the vertical dashes indicating the presence of a pulse at the instant of that particular strobe pulse. The system is controlled by a microprogram and the selections are entered by a keyboard. The time base, i.e. the period of strobe pulse, may be altered and the storage at 11 may be used to show data outside the present time range of the C.R.T.
