Title: Scattering apparatus for use in forming a layer of material
IPC: B27N3/12
Filed: 1975-05-09
Abstract: 1503527 Discharging hoppers B GRETEN [trading as BISON-WERKE BAHRE & GRETEN GmbH & CO KG] 9 May 1975 [9 May 1974] 19704/75 Heading B8S [Also in Division B5] Apparatus for use in forming a layer of material, for example during the production of a length of board such as chipboard, comprises a metering bin (1) having a discharge opening (2), Fig. 1 (not shown), from which the material falls via a triangular shaped deflector 7 on to two oscillating inclined sieves 10, 11, the grating size of the sieves being such that mediumcoarse and fairly-coarse particles move downwards over the sieve surfaces while very fine and fine particles fall through the sieves 10, 11 on to a layer carrier, for example a conveyer belt (not shown), the medium-coarse and fairlycoarse particles being fed to rotating scattering rollers 12, 13 which deposit those particles into the area beneath the sieves 10, 11, while the fine particles which pass through the sieves 10, 11 are caused to travel to the upper and lower sides of the medium-coarse and fairly-coarse particles by means of an air blower 37 which blows air in two horizontal opposite directions in the direction of the rollers 12, 13. Both sieves 10, 11 are pivotally mounted on respective levers 16, 22 and 17, 23, the upper edges 14, 15 of the sieves being attached to a plate 26 which is connected to an arm 27 movable to-and-fro in the direction of the arrow 30 by an eccentric drive 29, thereby oscillating the sieves. The scattering rollers 12, 13 are driven by means of belt drives 34, 33 from a motor (35). The apparatus is movable transversely to the direction of movement of the layer carrier.

Abstract: 852,602. Liquid-level gauges. LIPTON PRODUCTS Ltd. Nov. 18, 1958 [June 20, 1958], No. 19784/58. Class 123(1) A device for indicating the level of liquified gases in containers comprises a fluid-control valve body 19 which is screwable into the outlet of a gas cylinder 40, for example, and incorporates a magnetically operated gauge comprising a bar magnet 13 which is slidable in a bore 34 in the valve body 19 and influences a magnet 11 mounted on a pivot 12 in a valve-body recess 33. The latter, opposite a gas outlet 31, has no communication with the bore 34. A support rod 15 depending from the valve body 19 pivotally supports at its lower end an arm 25 extending between a float 26 and a counterweight 23. The magnet 11 carries a pointer which is moved over a scale on a transparent disc 8, held in the recess 33 by a circlip 5, in accordance with the angle of inclination of the float 26, the arm 25 being pivoted, adjacent the rod 15, to a doublecranked rod 17 carrying at its upper end the bar magnet 13. A filter sock 18 is mounted between two collars 16 fixed respectively to the valve body 19 and the rod 17. The gas-flow outlet 31 leads to an inlet passage 30 through a recess 32 which is closable by a valve seal washer 20 on a spool 22 which is equipped with a gland seal washer 21 and is rotatably connected to the shaft 2 of a control knob 1, the shaft 2 being screwed into a gland nut 3. The magnet 11 may be connected to the rod 17 by means of a lever arm, not shown, and two or more float arms may be arranged successively to move two or more rods 17, the floats, located at various levels, influencing the pointer over particular sectors of the scale.

Title: Method of producing monomeric methacrylic acid esters
Filed: 1936-07-20
Abstract: Monomeric methacrylic acid esters are manufactured by heating one or more polymethacrylic acid esters, or one or more mixed polymers of one or more methacrylic acid esters with one or more other polymerizable substances or of two or more of the said esters, to about 250--300 DEG  C., advantageously in the presence of inert substances, e.g. sand, barium sulphate or heavy spar, or of substances having an alkaline reaction, e.g. sodium carbonate or chalk, or, with reduced yield, in the presence of oxygen or of stabilizing agents.  The monomeric compounds can be reconverted into the polymeric form, e.g. by the action of peroxides. Examples describe the treatment, in the presence of sand, of: (1) polymeric methyl methacrylate; (2) polymeric ethyl methacrylate; (3) a mixed polymer of methyl methacrylate and butyl acrylate.

Abstract: 684,641. Processing of developer-containing photographic materials. STEVENS, A. H (International Polaroid Corporation). Jan. 29, 1947, No. 20324/50. Divided out of 684,592. Drawings to Specification. Class 98 (ii). A processing agent is confined between a photo-sensitive layer having a developable image therein and a superposed layer of sheet material, and the agent is caused to permeate the photo-sensitive layer and develop the image by progressively squeezing together the layers the processing agent being so confined as not to wet the outer surfaces of the layers during the squeezing. The processing agent may be such as to develop a negative image in the photo-sensitive layer and to form a positive thereof in a stratum of the lamination comprising the layers and the processing agent, the agent including a film-forming substance capable of giving a solid film. Alternatively a layer of sheet material for receiving a positive print may be immersed in a processing agent and pressed on to an exposed photo-sensitive layer. The subject-matter of this Specification is substantially the same as that of Specification 684,592, but the claims differ. Specification 684,594 also is referred to.

Abstract: 506,973. Spring frames for cycles &c. AUTO UNION. AKT.-GES. July 8, 1938, Nos. 20336 and 20337. Convention dates, July 8, 1937 and Feb. 1, 1938. [Class 136 (iii)] In a spring suspension for motor and other cycles &c. of the type in which the rear wheel is carried on each side by a sleeve slidably mounted under spring control on a guide member secured to the frame, the guide member constitutes a frame member connecting two longitudinal frame members between which the sleeve is disposed. In the motor-cycle suspension shown in Fig. 1, the longitudinal frame members 4, 5 on each side have secured to their rear ends shaped lugs 2, 3 adapted to receive a bolt 6, which clamps the lugs against the ends of a tubular distance-piece 7 surrounding the bolt. A sleeve 8 slides on the tube 7 under the control of a coil spring 9 and a rubber rebound spring or cushion 11, and is provided with a forked extension 13 secured between flanges 10, 12 and slotted to receive the wheel axle 14. The forked extension 13 on one side of the wheel is provided with a slotted lug 15 to which is adjustably secured the brake anchorplate 16, which is rotatably mounted on the axle 14. The sleeve 8 and the springs are enclosed in a protective tube 20 having flared ends by which it is clamped between the lugs 2, 3, the extension 13 passing through a slot 23. The path A of the axle 14 approximate to an arc B struck from the centre of the driving chainwheel, whereby the chain tension is kept constant. In a modification, the axle is given an arcuate path by means of a curved guide or distance-piece 7, the bolt 6 passing through a straight bore therein. The sliding sleeve 8 has a correspondingly-curved bore to engage the guide, and is formed in two parts provided with coacting positioning-faces and adapted to be detachably secured together by bolts.

Abstract: 290,074. Dobrowsky, E. Aug. 2, 1927. Vacuum engines.-A vacuum engine for operating an endless-display advertisement comprises cylinders 19, 20 separated by a head 23 containing a double-ended piston-operated valve 26, 27, connected to a suction pipe 32 from the engine of the vehicle, and a double-ended air valve 35. The pistons 21, 22 in the cylinders 19, 20 respectively are connected by a rod 18 provided with a pawl 17 which is adapted to engage a ratchet wheel 4 connected to a roller over which the endless web is led. The valve 26, 27 is longer than the thickness of the head so that when the piston 21, say, approaches the head 23 it strikes the valvet 26 to close the suction to the cylinder 19 and opens the valve 27 to admit the suction pressure to the cylinder 20. The air valve 35 acts in the opposite manner to that of the suction valve. The ratchet wheel is prevented from rotating in one direction by a pawl 17<1>.
