Title: Manufacture of semiconductor body
IPC: H01L21/3105
Filed: 1976-04-14
Abstract: 1536763 Processing semiconductors ITT INDUSTRIES Inc 14 April 1976 [18 April 1975] 15385/76 Heading H1K Unwanted spike-like projections which form during epitaxial deposition of a semiconductor layer 1 on a substrate 6 (Fig. 3) are removed by covering the surface with a thin coating 2, e.g. of thermal oxide affording mechanical protection, traversing a shearing tool 4 across the coating to break off the projections and treating with an etchant to remove damaged semiconductor material. As described the semiconductor is silicon and the tool may also be of pure silicon or be of or tipped with a hard plastics material. The substrate is preferably rotated on a turntable beneath the tool. If the etchant also acts on the protective coating treatment is continued to remove this, otherwise the coating is removed in a separate etching step.

Title: Improvements in and appertaining to stoking or fuel feeding mechanism for boiler and other furnaces
IPC: F23K3/16
Filed: 1924-06-26
Abstract: 240,233. Ryder, N. June 26, 1924. Mechanical stoking.-In steam generators having pairs of furnaces and fitted with stoking or fuel-feeding apparatus of the type in which the fuel is thrown or sprinkled into the furnaces by projectors supplied from hoppers or shoots, the operating mechanisms of the two fuel-feeding members are independently variable and are enclosed midway between the furnaces in a gearbox or casing arranged to form an oil-well for lubricating the moving parts. In the steam generator shown the fuel-feeding apparatus comprises hoppers C, C<1> fitted with reciprocating feed members 16, 16<a> and oscillating shovels or projectors 8 operated from a belt-driven shaft 2 by mechanism enclosed in an oil well and casing 14 provided with a detachable inspection cover 14<a>. This mechanism comprises a pinion 3 fixed to the shaft 2 and driving a spur-wheel 6 loosely mounted on the shaft 2 through spur-wheels 4, 5 fixed to a shaft 2<a>. The feed members 16, 16<a> are reciprocated by adjustable screws 18 carried by shafts 15, 15a which are rocked alternately by means of eccentrics 17, 17<a> on the shaft 2<a>. The projectors are withdrawn alternately by the engagement of arms 9 on their shafts 10 with pins 7, 7a projecting from the faces of the wheel 6 and are then moved forward to feed the fuel by springs 12, 12<a>. The springs 12, 12<a> are provided with adjusting screws 13, 13<a> passing through adjustable brackets 30, 30<a>. The travel of the shovels is rendered variable by the provision of several series of holes in the wheel 6 to receive the pins 7, 7<a>. The furnace is provided with reciprocating grate-bars 19 operated by cams 20, 20<a> on shafts 31, 31<a> rotated through worm and toothed gearing from a belt-driven pulley 21. The ends h of the grate-bars are supported by a cross-beam 27 connecting pillars 26, 26<a> which support the whole fuel-feeding apparatus independently of the boiler front.

Title: Plastically deformable laminated material in the form of sheets or web
IPC: B32B27/00
Filed: 1973-03-30
Abstract: 1398029 Flexible glass-plastics laminates LADCO ENTERPRISES Ltd 30 March 1973 15409/73 Heading B5N [Also in Division B8] A plastically deformable laminate which may also be folded and rolled, for use in packaging comprises a layer of thin glass flakes in close overlapping assembly bonded to at least one heat-deformable plastics carrier layer. The flakes may be joined by a binder. The flake layer may be bonded to one or more plastics layers, e.g. polyethylene, polypropylene, polystyrene or P.V.C., to form a symmetrical or asymmetrical laminate, or to a rigidifying layer of foam plastics. The binder should have a softening point and viscosity below that of any outer plastics layers and may be polyethylene or wax/polyethylene hot-melt material. The glass flakes may have a thickness below 200 Á, e.g. 3-50 Á and their transverse dimension may be greater than 3 times their thickness. The binder layer between the flakes should be less thick than the flakes. Adhesion between the flakes and the binder is facilitated by pretreating the flakes with a chlorosilane, chlorosiloxane, organic metal complex or metal oxide. If desired, an edge portion of the layer may contain no flakes. The flake layer may be made by casting and doctoring a mixture of flakes and unpolymerized binder which is subsequently polymerized, or by extruding a heated mixture of flakes and granular or particulate binder, in which case the mixture may be formed under vacuum and pressed out between cooled cylinders. The flake layer may be deposited on to an outer layer of the laminate or on to a relase surface; in one embodiment, the flake layer is formed between extruded plastics layers and the laminate is compressed between rollers. To facilitate degradation of the laminate, the plastics constituents may contain an ultraviolet light absorber and the glass flakes may be tinted.

Title: Improvements in or relating to straightening mechanisms for round bars
IPC: B21D3/04
Filed: 1951-07-06
Abstract: 688,807. Straightening by skew rolling. AKTIEBOLAGET MALCUS HOLMQUIST. July 6, 1951 [Nov. 10, 1950], No. 16156/51. Class 83 (iv). A straightening mechanism for round bars comprises a pair of skew rolls and a work support therebetween, each roll having a profile such that the work undergoes two or more alternately opposed angular deflections. Slidably mounted on a base and movable towards and away from each other by screws 4, 5 are two carriages 2, 3 each carrying a roll 6, 7. The rolls are mounted on spindles 8, 9 in housings which are rotatable about axes 12, 13 to vary the inclination of the rolls. The work is supported on a vertically adjustable bar and the relative speeds of the roll driving motors controlled so as to keep the work resting on the support. The profile of the rolls is such that the work undergoes two oppositely directed angular deflections and leaves the rolls along a line displaced laterally from the line of entry. In order to vary the angle of deflection for different materials, one or both rolls is or are adjustable axially either by a displacement along its shaft or by providing for a transverse movement of the roll housings relatively to the carriages 2, 3. Alternatively this result may be attained by using rolls built up of axially adjustable parts.

Title: A Process of Obtaining Marmalades and Jellies of Fruits, and in particular Grapes, having the Natural Perfume of the Fruit.
Inventor: MONTI EUDO
IPC: A23L21/12
Filed: 1918-10-11
Abstract: 133,456. Monti, E. Oct. 11, 1918. Marmalades, fruit jellies, &c.-To produce marmalades, &c. retaining the perfume and flavour of such fruits as grapes, strawberries, &c., which are easily deprived of their flavour by heating, the juices of such fruit are concentrated by freezing and mixed with jelly made from such fruits as apples, quinces, currants, or gooseberries, or from agar-agar, by concentrating in vacuo at a low temperature. The juices forming the jelly are concentrated in vacuo in the vessel 1 by means of lukewarm water flowing through the pipes 3, the vapours being condensed in a condenser 7, until the proportion of dry matter is from 80-88 per cent or rather more. It is then transferred to the jacketed vessel 12, where it is digested at from 35-40‹ C., being continually stirred to prevent premature jellificataon. The flavouring-juices are then mixed with it. If the dry matter in the resulting mixture is less than 65 or 70 per cent of the whole, the surplus water must be evaporated at low pressure and a temperature of 20-25‹ C. ; but this is better avoided. The resulting jelly is sterilized by repeated warming to about 50‹ C. in known fashion. The apparatus for concentrating the grape, strawberry or like juices is shown in Fig. 2. In a jacketed vessel 18 are two rotating drums 19 cooled internally by the expansion of ammonia or otherwise. The ice forming on the surface of the drums is removed by adjustable wooden scrapers 20 and falls into a perforated trough 22, whence it is removed by a conveyer 23. Juice adhering to the ice escapes through the perforations in the trough, and the concentrated juice escapes by the pipe 26. Any juice adhering to the ice is removed by known methods. Specifications 19645/03, 18138/05, 9205/06, and 21287/12, [all in Class 29, Cooling &c.], are referred to.
