Title: Improvements in or relating to apparatus for handling coal or other granular materials
IPC: B65G65/44
Filed: 1947-02-18
Abstract: 629,550. Conveyers ; unloading vehicles ; shoots. JONES, Ltd., W., and FERGUSON, T. M. Feb. 18, 1947, No. 4708. [Classes 78 (i) and 78 (iv)] Coal is discharged from wagons by pushing it through a side opening by a push plate 4 depending from and powerfully moved along the jib 3 of excavating or like equipment, and directing it on to a conveyer belt which can be adjusted vertically and horizontally. The conveying means comprises a portable conveyer consisting of a frame from the principal uprights 5 of which is slung a belt conveyer in two sections 6 and 9, each section being raised or lowered independently by cables 8 and 7 respectively. The lower end of the belt runs into a boot 10 fed from a shoot 11 of frusto-conical shape which may have internal ribs and is in turn fed from a tray 12 having walls on three sides, the fourth side having a lip 13 adapted to overlie the wagon floor as shown in the plan view, Fig. 1, the wagon door 2A being turned down as shown in Fig. 3. Triangular side plates 14 are disposed to provide baffle plates directing the coal from the truck opening into tray 12. The wheels 15 of the portable conveyer can be turned to the dotted line position for slewing the frame about the axis of the shoot 11 as shown by the arrows, Fig. 1. Shoot 11 is preferably rotated continuously and tray 12 may also be rotated. Handles 22 fulcrumed on a pair of wheels 20 provide a means for lifting the boot of the conveyer when it is to be moved. Fig. 4 shows an alternative arrangement in which the door 33 of a wagon forms part of a directing shoot comprising two triangular side members 31 hooked over the side of the wagon and joined by a chain 32 upon which the door rests when lowered.

IPC: A47B81/06
Filed: 1918-03-18
Abstract: 121,053. Denny, J. M. T. March 18, 1918. Contents, delivering etc.; fittings, internal.- Gramophone records A<2>, Fig. 1, are held in compartments A, A<1> of a cabinet or receptacle between sheets B of cardboard, wood, vulcanite, &c., which are strung on rods B<2>. The sheets and records are pressed together by a plate (not shown) which, when pushed up against the outer sheet, is held in position by suitable means; these may be steel points at top and bottom taking into the material of the cabinet, the upper points being spring-mounted and depressible by means of a handle. A finger D<4> in each compartment is carried by a sleeve furnished with a handle D<2> and slidable on a fixed rod D. A ribbon E connects the back edges of the sheets B and has its parts coloured in accordance with a previouslyprepared register, an opening E<1> in a hinged part E' serving for viewing the ribbon. The finger D<4> may thus be set opposite any desired record, which, on depressing the handle D<2>, is then pushed forwards away from a bearing-batten A<3>, for withdrawal. Pieces of tape attached to each sheet B become drawn out on withdrawing the records, and serve as indications for re-insertion. In another construction, the finger D<4> is mou:ated on a notched handled tube G, Fig. 3, slidable along the rod D, a spring blade indicator G<1> being adapted to engage in the notch of the number found on the register.

Abstract: 659,199. Dry contact rectifiers. GENERAL ELECTRIC CO., Ltd., ROBERTSON, W. B., and TURNER, H. C. Feb. 15, 1949, No. 5233. [Class 37] A method of manufacturing a rectifier includes the steps of assembling a number of selenium rectifier elements into a stack, and subjecting the elements to an electroforming process whilst pressure is maintained between the stack ends. In one embodiment the elements are threaded on to an insulated rod 4 with interleaved spacing washers 2. Pressure is applied by screwing up nuts 8 against a spring 9, and current is supplied through metallic plates 6. The stack is then unclamped and the elements used to build rectifiers of the stack type. Alternatively the elements may be assembled as a complete rectifier, with cooling fins &c., and the electroforming process performed on the completed unit.

Inventor: LAMB FRANK
IPC: D04H1/54
Filed: 1965-02-06
Abstract: Cyclic acetals are obtained by condensing chloral or its hydrate with di- or polyhydric alcohols.  Side-chains if present may then be oxidized or esterified or both.  In the examples: (1) glycerol is condensed with chloral; (2) propylene glycol is condensed with chloral hydrate; (3) pentaerythritol is condensed with chloral, both monocyclic and dicyclic acetals are obtained; (4) trimethylolpropane is condensed with chloral hydrate; (5) ethylene glycol is condensed with chloral; (6) trichlorethylidene-glycerol is refluxed with thionyl chloride to yield 2 - trichloromethyl - 4 - chloromethyl - 1,3 - dioxolane; (7) 2-trichloromethyl-5,5-bis-hydroxymethyl-1,3-dioxane is esterified by treatment with acetic anhydride and sodium acetate; (8) trichlorethylidene-glycerol is similarly acetylated to trichlorethylidene-glyceryl acetate; (9) trichlorethylidene-glycerol is esterified with trichloracetyl chloride in pyridine; (10) trichlorethylidene-glycerol is oxidized with alkaline potassium permanganate to yield 2-trichloromethyl-4-carboxy-1,3-dioxolane; (11) trichlorethylidene-glycerol is oxidized with concentrated nitric acid and the product reacted with the addition compound of boron trifluoride and methanol to yield 2-trichloromethyl-4-carbomethoxy-1,3-dioxolane; (12) trichlorethylideneglycerol is reacted with phthalic anhydride in pyridine to yield mono-trichlorethylidene-glyceryl phthalate; and (13) the corresponding half-ester of succinic acid is made similarly.ALSO:Polyester fibres are bonded by contacting at least part of the outer surface of a mass of the fibres with a cyclic acetal containing in its molecule the grouping: <FORM:1099925/D1-D2/1> where n = 0 or 1.  These acetals may be obtained by condensing chloral or its hydrate with suitable di- or polyhydric alcohols. If the alcohol has three or more hydroxyl groups, those not acetalized may be chlorinated, esterified or oxidized to carboxylic acids, which may then be esterified.  The acetal may be applied by steeping the mass of fibres in the liquid acetal, or by spraying the acetal on to part or all of the surface of the mass of fibres, and if desired into some or all of the interstices between the fibres.  An elevated temperature is preferably used. The product is useful for packing, filling or thermal or electrical insulation.

Abstract: 413,421. Controlling apparatus by light. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Feb. 22, 1933, No. 5453. Convention date, Feb. 22, 1932. [Class 40 (v).] An electric control for work-copying machines of the type employing cutting or lathe tools is characterized in that the movements of the feeler touching the model deflect beams of light which by acting on photo-electric cells control the corresponding movements of the tool slide and feeler slide. The tool and feeler apparatus are rigidly connected and the feeler P, which is mounted in its support by a cardan joint K, touches the model with one end, while the other end carries a mirror Sp. A stop on the feeler is pressed towards its guide bush R by an adjustable spring F, and the feeler is held central by four independent adjustable springs G. Normally a light beam falls on the mirror and is reflected on to a photo-electric cell O, whereby is closed a circuit of known type which moves the feeler and tool apparatus towards the model and the work. When the feeler touches the model it is pressed back and the reflected beam strikes against the ring-shaped photo-electric cell I, whereby the advancing movement of the tool is produced. If the feeler is pressed sideways as it moves over the model, the light beam falls on the photo-electric cell II whereby the advancing movement of the tool is stopped and the tool and feeler are retracted until light again falls on the cell I. The photo-electric cell III serves to cut out the plant and/or to give a warning signal should the feeler be displaced by any excessive amount. The deflections of the mirror may be magnified by compound mirrors or other equivalent optical systems.
