Title: Improvements in or relating to sluice boxes and other receptacles
IPC: B03B5/26
Filed: 1931-12-22
Abstract: 387,479. Washing granular materials. BYRNE, E. J., Down Head, Seaford, Sussex, and RYAN, J. P., Kamunting, Perak, Federated Malay States. Dec. 22, 1931, No. 35458. [Class 82 (ii).] A sluice box, sand shoot, dredger, mechanically actuated shovel, or other receptacle which is subjected when in use to abrasive action by earth, sand, gravel, water, &c. is provided with a protective lining built up of individually removable sections each of which comprises a plate of metal, wood, or other suitable material to which a rubber facing is secured, preferably by vulcanizing. The sections are preferably secured to the receptacle by bolts passing through the plates and the side or bottom of the receptacle, the bolt head being preferably covered by the rubber so that it is protected from abrasion. In the form shown for lining a sluice box A the sections are formed of rubber facings B vulcanized to expanded metal sheets C to each of which is welded one or more bolts D secured by nuts E on the under side of the receptacle. The sections are made so that they are interchangeable and are preferably of two sizes B and b<1> so as to break joint, with narrower sections b<2> at the sides. Instead of expanded metal sheets cast metal plates which may be cast round or integrally with the bolts may be used. Alternatively the bolts may be separate from the plates, e.g. T-headed bolts may be inserted from below through slots in the plates and secured by rotation. Instead of vulcanizing the rubber sheets to the metal plates the edges of the sheets may be turned over and under the plates so that the sheets are gripped in position when the securing nuts are tightened. The rubber sheets are preferably made slightly larger than the metal plates and the edges of adjacent sections may be inclined so that on tightening the securing means the edges are drawn together. Specification 286,168 is referred to.

Title: Improvements in and relating to combined hydraulic slip coupling and positive clutch
IPC: F16D47/06
Filed: 1937-12-22
Abstract: 484,394. Clutches. DEUTSCHE SCHIFFUND MASCHINENBAU AKT.- GES. Dec. 22, 1937, No. 35496. Convention date, Dec. 24, 1936. [Class 80 (ii)] The driven member B of a hydraulic coupling is, together with its shaft E, urged towards the cover C, secured to the driving member A, by a spring F, such movement being controlled by a sleeve H splined on the shaft E and co-operating with a shoulder Q on the shaft. The sleeve H is moved by a nut N actuated by a screwed spindle M and acting on the sleeve through a spring K and a lever P. With the nut in the starting position shown, a slipping drive is . transmitted through the hydraulic coupling. On turning the hand-wheel L so as to move the nut N to the right, the sleeve H moves to the right so as to allow the spring F to act and engage a friction clutch D between the members B, C. The parts A, E are thus synchronized. On moving the nut further to the right, a dog clutch J between the parts C, H is engaged, whereby a positive drive from the member A to the shaft E is transmitted. If the dogs J are not in register, the spring K is compressed until slip in the friction clutch permits the dogs to engage.

Title: Improvements in or relating to processes for the production of magnesium sulphide and metallic magnesium
IPC: C22B26/22
Filed: 1935-12-23
Abstract: Magnesium is obtained from magnesium compounds, such as the sulphate, chloride, or oxide, by heating them with ferric sulphide or its components to form magnesium sulphide and reducing the sulphide by heating it with a reducing agent such as calcium carbide or silicide, carborundum, sodium, or aluminium in an atmosphere of a reducing or inert gas and in the substantial absence of moisture, nitrogen, or oxygen.  Ferric sulphide for use in the process may be obtained by heating pyrites with ferrous sulphide or with iron and sulphur.  When the sulphide is formed from magnesium chloride, the ferric chloride also formed is distilled off, whilst the heating of magnesium oxide with ferric sulphide is carried out in the presence of carbonaceous material so that metallic iron is formed from which the magnesium sulphide separates as a slag.  Specification 465,421 is referred to. According to the Provisional Specification, an alkali metal sulphide may be used in the formation of magnesium sulphide; for instance when sodium sulphide is heated with magnesium sulphate, magnesium sulphide and sodium sulphate are obtained.ALSO:Magnesium is obtained from magnesium compounds, such as the sulphate, chloride, or oxide, by heating them with ferric sulphide or its components to form magnesium sulphide and reducing the sulphide by heating it with a reducing agent such as calcium carbide or silicide, carborundum, sodium, or aluminium in an atmosphere of a reducing or inert gas and in the substantial absence of moisture, nitrogen, or oxygen.

Filed: 1959-10-20
Abstract: 943,993. Thermographic copying sheets. MINNESOTA MINING & MANUFACTURING CO. Oct. 20, 1959 [Oct. 20, 1958], No. 35595/59. Heading G2C. A thermographic copy sheet having improved resistance to discoloration under illumination and to fingerprinting consists of a support and a coating thereon including as image-producing reactants a finely divided particulate silver soap and a reducing agent therefor and homogeneously associated therewith zinc oxide and a solid fusible pure hydrocarbon thermoplastic terpene resin of zero acid number. The zinc oxide and terpene resin particles provide a white opaque ground and on thermographic exposure the silver soap and reducing agent produce a visible image in the heated areas while the resin there fuses to a transparent mass disclosing the image. The quantity of terpene resin is preferably from 2 to 5 times the quantity  of the silver soap by weight and forms from 2/5 to 2/3 of the coating by volume. Typically white kraft paper is coated with a ball-milled dispersion in acetone of silver behenate and behenic acid, a powdered terpene resin of zero acid number and a softening poing of 135C., zinc oxide, polyvinyl  acetate, and phthalazin-1-one, to which is added just before coating methyl gallate. A thin overcoat of a ball-milled acetone-dispersion of behenic acid, powdered silica, cellulose acetate, phthalazin- 1-one may be applied. Instead of silver behenate, silver salts of stearic, oleic, lauric hydroxystearic, acetic, phthalic, terephthalic, butyric, m-nitrobenzoic, salicylic, phenylacetic, pyromellitic, #-phenylbenzoic, undecylenic, camphoric, furoic, acetamidobenzoic or o-aminobenzoic acids may be used together with the free acids where appropriate or another waxy acid if the other components are not waxy. If the silver soap is waxy the free acid may be omitted. The methyl gallate reactant may be replaced by protocatechnic acid or hydroquinone while the phthalazinone may be replaced by phthalic anhydride. Polyvinyl butyral and cellulose acetate butyrate may be used as binders in place of polyvinyl acetate.

Title: Improved mashed potato product and method for production by continuous process
IPC: A23L19/12
Filed: 1962-09-19
Abstract: 1,012,458. Dehydrated potatoes. AMERICAN POTATO CO. Sept. 19, 1962 [Sept. 21, 1961; Sept. 10, 1962], No. 35698/62. Heading A2D. A continuous process for making an easily reconstituted dehydrated granular mashed potato product comprises peeling, slicing, rinsing, optionally precooking and cooling, steam cooking the potato, or alternatively scrubbing, baking and cutting unpeeled potatoes, mixing the product at 130‹-150‹F. in a mixer with addition of water optionally containing additives (e.g. sulphite salts, mono- and di-glycerides, sodium acid pyrophosphates, BHA and BHT and milk solids to produce a free flowing slurry containing less than 17% (preferably 10-14%) potato solids, removing debris from the slurry in a finisher, and spray drying the resulting slurry in a stream of hot air or on to a heated surface, the process allowing for the production of a product containing substantially 100% unicellular, or multicellular potato particles or a mixture of each. The mixer consists of a cylindrical housing 16 Fig. 2 which receives a screw 17. A perforated wall 18 divides -the mixer into a lower chamber which accommodates a paddle assembly 19 mounted on a shaft 21 upon which flight 22 of screw 17 is also mounted. Water and cooked potato material are fed by screw 17 through the perforations where paddles 19 mix -the resulting slurry which is fed to the finished Fig. 1 (not shown). The debris is removed from the slurry in the finisher which may be of a conventional design adapted to meet the requirements of the present process. On leaving the finisher the slurry is pumped to a spray drying device. In one form the spraying device comprises a nozzle into which the slurry flows in the annulus between concentric pipes 37 and 38, (Fig. 3), the dispersing gas (air or steam) flows through inner pipe 37 in which there is concentrically located by pins 41 a longitudinally adjustable mushroom-headed stem 39. At the exit 43 the two fluids mix and the potato slurry is sprayed into a drying chamber (Fig. 1, not shown) supplied with air at 250‹-400‹F. The arrangement is adapted to produce a unicellular or multicellular product by adjusting the slurry feed rate, air temperature and air flow. The fine particles entrained in the air are recovered in a dust separator cyclone or by other means and may be combined with the balance from the dryer floor. An additional rewetting and drying step is described for producing a practically 100% multicellular product. Alternatively, after leaving the finisher the slurry may be sprayed on to the surface of a heated rotating drum. A further step is also described for forming the slurry from potatoes which have a high sugar content in which the slurry is dewatered by filtering or centrifuging, the water discarded and replaced by fresh water containing the additives. Specifications 740,745, 767,903, 773,361 and 791,193 are referred to.

Title: Live roller conveyor
IPC: B65G47/26
Filed: 1965-08-23
Abstract: 1,096,350. Roller conveyers. ALVEY CONVEYOR MANUFACTURING CO. Aug. 23, 1965 [Sept. 14, 1964], No. 36077/65. Heading B8A. A live roller conveyer comprises transport rollers 2 driven by the upper run of a belt 7 which would lie in a plane below the plane of the lower edges of the rollers 2 except that it is lifted into driving engagement with the transport rollers 2 by load compensators 15. Each load compensator comprises a pair of hangers 11 rotatably journalled from side rails 1 and supporting a yoke 12 on pivot pins 13. Each yoke 12 carries an idler roller 14 and an adjustable counterweight 17 which biases the belt 7 into frictional driving engagement with the rollers 2. The load compensators 15 are initially adjusted for a usual conveyer load, thus establishing the amount of frictional loading for normal operation. Under the influence of heavier loads or load stoppage the transport rollers 2 have a higher than normal frictional load which increases the drag on the belt 7. The upper run of the belt becomes more taut and the tensioning is absorbed by the load compensators 15 to afford a uniform frictional drive. The load compensators 15 provide self-centring of the belt 7, since when the belt 7 runs off centre as at 7a, the resultant differential tilting of the sides of the yoke 12 introduces a centring force.

Abstract: 1321256 Time switches H OBERGFELL 24 July 1970 [24 July 1969] 36129/70 Heading H1N A programme controller, for a washing machine or the like, in which a motor drives a programme cam through a planetary transmission comprising sun-wheel, internally toothed outer ring and planetary gear assembly one element being coupled to the motor, one to the cam and the third being normally free but can be held stationary to cause the motor to drive the cam, has an overrunning clutch incorporated in the transmission and the clutch and planetary transmission are constructed of plastics materials. A stepping drive using the above arrangement is described. A snail cam (1, Fig. 3, not shown) rotating continuously at one r.p.m. reciprocates a slider (2) to ratchet a pivoted plate (6) until a projection (21) thereon cams a locking plate (17) into engagement with the third element (19) of the planetary transmission to hold it stationary, causing drive to programme cams (9a and 9b). Cam(9b) then pivots a plate (10) to release a retention pawl (14) and slider (2) from the ratchet teeth on plate (6), whereupon springs (5, 8 and 18) restore respective plates (2, 6 and 17) to their rest positions. The profile of cam (9a) locates the rest position of projection (21) and thus of plate (6); this determines the number of ratchet teeth to be moved before the next locking of the transmission occurs and hence the time interval between programme steps.

Title: Apparatus and process for applying a resin coating to the inside of a pipe
IPC: B05D7/22
Filed: 1962-09-24
Abstract: 954,828. Coating surfaces. REPUBLIC STEEL CORPORATION. Sept. 24, 1962 [Oct. 12, 1961], No. 36164/62. Heading B2B. A process for coating the interior of a pipe comprises the steps of feeding a finely divided resin powder at a controlled rate into a dust chamber, applying compressed air through at least one air inlet in the lower region of said chamber and at least one air inlet in the upper region of said chamber, passing the resulting cloud of dust from said dust chamber into a lance of appropriate length having an inner passageway therethrough, maintaining said passageway at a temperature less than will cause adherence of said powder, effecting deflection of the resin powder after it has passed through said lance on to the inner wall of the pipe, and maintaining the pipe at a temperature suitable for causing softening and adherence of said resin to the inner wall of the pipe. The lance and the pipe are movable relative to one another. The pipe may be heated by radiant heaters and burning gases before and/or during the coating operation. The means for protecting the lance from heat radiated from the pipe may be an air-cooled or water-cooled jacket The deflector means or nozzle presents a curved or straight angular surface in the path of the resin powder, e.g. a conical surface. The pipe is pre-cleaned by alkaline cleaning and acid pickling. The resins specified are epoxy resins, polyethylene, polyvinyl butyrates, polyacrylates, acrylic polymers modified with melamine or epoxy resins, methyl methacrylate polymers modified with solid butyrated melamine, polyvinyl resins and nylon. (Fig. 1) Powder is fed from hopper 1 containing vibrators 2, via charging means 4 into dust chamber 6, in which the powder is subjected to air streams from inlets 41, 42, 43, 44 (Fig. 3) and 44<SP>1</SP> (Fig. 4). The cloud of powder passes via collector head 9 into inner passageway 13 of lance 10 and is deflected on to the wall of pipe 14. In Fig. 1 the pipe is moved over the lance by driven rollers and in Fig. 2 the lance is moved into the pipe. The lance may have wheels or spacers to keep the lance in the middle of the pipe, in which case the coating is done on the withdrawal stroke. Pipes may be done successively as shown in Fig. 4 or may be done simultaneously, the apparatus having a number of lances each of which may be connected to the same dust chamber or to separate dust chambers.
