Abstract: 1347459 Castors HUFA-ROLLEN HUGO FASSBENDER K G 26 May 1972 [31 July 1971] 25030/72 Heading A4U [Also in Division F2] A castor assembly includes a steering lock 26 by which a wheel 3 is locked in a straight line of travel by the engagement of a tang 33 on a locking lever 32 in a notch 34 in a fork base plate 5. The locking lever 32 is loaded by a spring 35 and is pivoted on a lock support plate 38 on which is also pivoted an actuating lever 27 by which the locking lever is released, each lever being retained in locked and unlocked positions by an over-centre device. Pivot pins 30, 39 of the levers 27, 32 have bearings in side webs of the support-plate 38, which is secured to a base plate 9 of the assembly, the spring 35 being mounted on the pin 39 and having upper and lower arms bearing on the support plate 38 and on a lateral part 42 at the tanged end of the locking lever 32. An actuator bar 31 extending between side webs 28 of the actuating lever 27 bears against the locking lever so that in unlocked position, Fig. 1, in which the locking lever forms an approximately horizontal extension of the support plate 38, the inner end of the lever 27 is held by the spring 35 in engagement with the face 38" of the plate 38. When the actuating lever is depressed the bar 31 moves through a relatively small angle α, past a dead-centre line X-X and through a larger angle # into its locked position, the thrust of the spring snapping the locking lever 32 into its locked position in which edges 45 of walls 28 contact edges 46 of the locking lever or the tang 33 abuts the upper surface of a spring 19 secured to the base plate 5. The spring 19 has a lower part with a projection 20, adjustable by a screw 21, and an upper part having teeth 18, the projection 20 engaging the periphery of the wheel, to prevent rolling movement of the wheel 3, and the teeth 18 engaging recesses 17' in a plate 17, welded to the lower end of a plunger 13, which is vertically and non-rotatably movable in a bush 11 welded to the base plate 9, to prevent swivelling of the castor when the plunger is depressed, against the action of spring 25, by pressure on a head 14. In a modification, side webs of the locking lever support a pivot pin for the actuating lever which is urged by a single-arm spring to bear, in the unlocked position, by an intermediate part on an edge of the lock support plate and by an upturned inner end on the under surface of the lock support plate. In the depressed, locked position of the actuating lever the edges of the side webs thereof bear on the undersurface of the lock support plate.

Title: An improved method of and apparatus for burning a low ash content particle-form fuel
IPC: F23C3/00
Filed: 1955-09-01
Abstract: 781,825. Pulverized fuel-fired combustion apparatus. BABCOCK & WILCOX, Ltd. Sept. 1, 1955 [Sept. 7, 1954], No. 25116/55. Class 51 (1). A particle-form fuel of low ash content is burnt in a cyclone furnace in the presence of air and a slag-forming material. The latter may be a high volatile pulverized coal but if of a non-combustible refractory nature then a supplementary fuel, such as oil, gas or pulverized coal, may require introduction into the furnace. In the furnace shown for burning " petroleum coke " such material is fed nearly tangentially carrier air borne via a series of ports 33 into the combustion chamber 12 immediately behind, in the direction of gas whirl, the secondary air flow tangentially introduced through a damper 32 controlled slot 31. The " coke " drops from hopper 34, feeder 35 and rotary seal 36 into the carrier air flowing through the duct 40. The slag-forming material is either a low-temperature clay or sand or lime or any other non-combustible refractory and is passed to the furnace from a hopper 50 through a feeder 51, rotary seal 52 and a duct 28 in which a carrier airstream flows. In order to minimize the use of new material, slag from the furnace is recovered from a quenching pit 26 in a granulated condition and fed to the hopper 50 through a pneumatic conveyer 48. An oil burner 27 is provided, the necessary primary air entering through the duct 28 whilst tertiary air enters in controlled quantities through a duct 30. A whirl motion is imparted to the air and entrained solids from the duct 28 in a furnace inlet section 16. The slag-forming material may be a high-volatile bituminous coal supplied with primary air and, if desired, granulated slag from hopper 50, through duct 28 and section 16. In such a case the burner 27 may be omitted. If a gaseous supplementary fuel is used then the latter is preferably introduced through burners positioned in the air slot 31. Specification 552,747 is referred to.

Abstract: 500,747. Fibrous plastic compositions. MASONITE CORPORATION. Sept. 18, 1937, No. 25390. Convention date, Oct. 9, 1936. [Class 70] [Also in Groups IV. VIII, and XIII] Sheets, boards, or other products are made from lignocellulose such as wood chips, sawdust, cane bagasse or straw which has been converted to a predominantly plastic state by the action of heat and moisture as described in Specification 497,477, [Group IV], by drying completely the converted material, further heating if desired, and subjecting it to pressure while completely dry and hot. The converted material is comminuted by explosive discharge from the pressure treatment vessel, or in a rodmill, prior to the shaping operation. The comminuted converted material formed into a pulp with water with or without a small quantity of petrolatum or solid paraffin, may be converted into a thick or thin paper-like web which, as a web or cut up into sheets, is dried, further heated, and compressed while hot between rollers or platens, heated or unheated, plain or patterned. A web produced by a paper-machine 10 is squeezed by rolls 12, and cut by a knife 16 into sheets which are introduced successively into the various decks of a drier and heater 20 by a swinging conveyer 18 floored with driven rollers. In the drier 20a the sheets, carried by driven rollers 22, are exposed to hot gases from a gas burner 23 circulated by a blower 26 through piping 28, tapered cross ducts 34, outlet spouts 36, chamber 20a, flared inlet spouts 40, tapered cross ducts 42, and conduit 44. An adjustable damper 32 allows excess gases to escape. The dried sheets, which may be further heated in a chamber 20b by a similar circulation of hot gases, are removed successively from the decks of the heater by a swinging roller-floored conveyer 80 and consolidated between rolls 82 which may be heated by gas jets 84 and enclosed in hoods 86. One or more thin paperlike sheets, crÛped if desired, may be dried, heated, and pressed between corrugating rollers to produce a single or multi-ply corrugated board. Binders, fillers, and pigments may be added to the converted lignocellulose material. U.S.A. Specifications 1,578,609 and 1,824,221 also arc referred to.

IPC: C09D7/00
Filed: 1950-10-19
Abstract: Solutions of the resins described and claimed in Specifications 703,407 and 703,408 are used for coating, e.g. wood and leather. In one example the resin, zein and o- and p-toluene ethyl sulphonamides are dissolved in methanol to give a solution, which may be thinned, e.g. with a methanol-toluene mixture, for application to a wood surface.  This solution may be modified by addition of organic or inorganic pigments, co-polymers of butadiene and acrylonitrile, alkyds, oil-fatty-acid-modified alkyds, oil-soluble phenolic resins, rosin, hydrogenated rosin and dehydrated castor oil.  In another example an aqueous solution is made by dissolving in water the resin, an alkali-soluble protein, e.g. casein, soya bean protein, gliadin or zein and an alkali, e.g. ammonia, borax, sodium phosphate or morpholine.  In a further example the composition consists of the resin, o- and p-toluene ethyl sulphonamides and methanol, with or without toluene and Caranda or carnauba wax.  The composition in the last example is a methanol-toluene solution of the resin, zein, Caranda wax and o- and -p-toluene ethyl sulphonamides.

Title: Gun for driving pins, nails and the like into solid materials
IPC: B25C1/14
Filed: 1958-08-14
Abstract: 901,612. Cartridge-operated tools for driving pins &c. into structures. ANSTALT FUR MONTAGUE-TECHNIK VADUZ. Aug. 14, 1958 [Aug. 16, 1957], No. 26107/58. Class 119. Relates to a cartridge-operated tool for firing pins into structures of the type in which the pin is driven by a captive piston or hammer forced along the barrel by the explosive gases. According to the invention the cartridge chamber 7 is axially displaceable and in the ready-to-fire position is disposed with the base 6<SP>1</SP> of the cartridge 5 adjacent a firing pin 39a projecting out of the rear end of the piston 2, 3, the cartridge base containing the firing charge, thus facing forwardly, i.e. in the direction of driving. The cartridge chamber 7 slides in a block 8 rigidly connected to the butt 21 which is provided with a gas expansion chamber 34 in communication with a bore 35 in the block 8. A pin 19 with sealing grooves extends into the chamber 7 and can be adjusted to vary the size of the combustion chamber. On pressing the trigger 31 a ring-shaped hammer 22 is first pressed back against the action of a spring 23 until a pawl 25 disengages from a slot 24 and the hammer 22 springs forward. Due to the impact of the hammer 22 on the block 8, the cartridge chamber 7 is thrown forwardly so that the cartridge base 6<SP>1</SP> strikes against the firing pin 39a. The gas pressure developed presses the cartridge base 6<SP>1</SP> and the chamber 7 against the head 3 of the piston and they follow the piston during its consequent movement along the barrel until the chamber 7 is halted by engagement of an abutment 11 with a shoulder 10 on the block 8. This causes forward rejection of the cartridge and at the same time openings 12 in the chamber 7 are uncovered to permit the residual gases to d scharge through the bore 35 to the expansion chamber 34.
