Title: Improvements relating to moulding plastic materials
IPC: B29C33/00
Filed: 1942-02-16
Abstract: 555,832. Moulding buttons &c. by pressure. GOODE, J. H. Feb. 16, 1942, No. 2054. [Class 87 (ii)] In moulding charges of plastic material which are placed between dies in series in a bore along which the dies slide and approach one another as the charges take shape, any air and surplus material being released from the edges of the dies into a vent running longitudinally of the bore, the dies project into the vent, and pressure is continued until the adjacent projections come into contact. As shown, the bore 1a has a narrow channel 12 leading to a smaller bore 13, and the dies have projections 14 which extend into the channel and bore and kev the dies to ensure that projections 15, 16 thereon register with contiguous projections on contiguous similar dies. The bore 13 may be cleaned with a ram-rod. The dies shown are for forming buttons, one face of a die forming the back of a button and the other face the front. Heating elements may be housed in chambers 3. The bore may be formed by a split sleeve into the split in which the dies project. The sleeve may be used in conjunction with a tapering hole, and may be adjustable. A plurality of bores may be formed in one mould. Pressure may be applied to the dies and charges from either end of the bore, an abutment being provided at the other end, or from both ends, the pressure being applied instantaneously or in progressively greater followed by progressively less amounts. The pressure may be applied through a spring or by fluid means which may be applied continuously or intermittently. Subsidiary pressure, acting in a different direction, may be applied to resist any tendency of the dies to deflection from their correct position. The edges of the moulded articles may be shaped by the bore, by dies, or by separate pieces. In making rings a solid core may be positioned centrally within the bore. During moulding, progressively greater or progressively less heat may be applied. To permit extraction of the moulded articles the heat may be increased or the mould may be cooled. Specification 557,345 is referred to.

Abstract: 1337305 Decorative panels GENERAL ELECTRIC CO 15 Jan 1971 [16 Jan 1970] 2108/71 Heading B6G A plastics panel having a front surface containing grain structure simulating that of a master panel has adhered to its back surface a material such as polyurethane foam, a tarbased substance, or wood, to provide structural rigidity and the front surface is coated with a glaze containing a filler and a top coat. The panel may be of polystyrene and the master panel, which may bear an ornate pattern, may be of wood, slate or brick. The plastics panel is made by cleansing the surface of a master panel with a solvent, forming a silicone rubber casting of the surface, forming a ceramic replica of the casting, forming a metallic casting of the ceramic replica, injection moulding the panel from the metal casting, applying foamed plastics or other material to the back surface, spraying the front surface with glaze containing a filler, wiping off the excess glaze to give dark and light streaked highlighting and applying a top coat. A number of the panels may be fused together by sonic welding to form the walls of an enclosure prior to application of the glaze. The panels may be particularly used in the manufacture of a gramophone cabinet comprising four vertical sides, a pivotally supported lid, top portions on either side of the lid, a supporting tray for the record changer and amplifier, and a record storage bucket. The lid of the cabinet may have a plastics liner secured to its inner surface with a polyurethane filling in between, the liner also being subsequently sprayed with glaze containing a filler.

Abstract: 1,090,915. Rotary wing aircraft. BOLKOW G.m.b.H. Jan. 18, 1965 [Jan. 16, 1964], No. 2136/65. Heading B7W. [Also in Division G3] A helicopter rotor blade is mounted for leadlag pivoting and is given an impulse, producing a movement about the lead-lag hinge, at a predetermined angular position to ensure that the pivoting motion is correctly phased. In Fig. 1, the rotor blade 31, pivoted at 60 is connected to the piston 28 of a hydraulic servomotor to which fluid is supplied from a pump 7 and reservoir 6, through a rotary valve having a non-rotating part 5 and a part 5a rotating with the rotor and the rest of the hydraulic system. For 5 degrees in each revolution, the valve is in the position shown allowing fluid to move to the right a shuttle valve 19 and the piston 28. For another 5 degree period, the valve is in a position in which it reverses the connections to the lines 11, 13, and the shuttle valve 19 and piston 28 are moved to the left. These two periods are 180 degrees apart, and at other times the valve part 5 closes the conduits 11, 13 allowing the shuttle valve 19 to centralize and connecting the two ends of the cylinder 2 by a passage 22, which contains a fluid pressure operated valve 25. The rotor blade thus pivots freely on the hinge 60. The lead-lag pivoting may be started and stopped gradually by moving the part 5 of the rotary valve axially to vary the alignment of the passages such as 8 with the conduits such as 11, 10 thus to vary the pressure in the servomotor and to vary the pressure on the valve 25. which when closed, damps the pivoting of the blade. The hydraulic servomotor may be replaced by an electric or pneumatic servomotor.

[Class 100 (iv).] Platen-rotation for blanking.-In a page- .printing telegraph, the paper controls means for permitting repeated operation of the linespacing mechanism to effect blanking. In the apparatus shown in the Figure, a web 2 having perforations 13 at page-length intervals passes over a platen 1 provided with line-spacing mechanism comprising a rocking arm 4 connected to a bell crank 7 which abuts on a slide 8 controlling a dog 10 forming part of a onerevolution clutch. The arm 4 is connected also to a bar 3 which is released by the selector-bars to initiate line-spacing. Normally only a single line-spacing movement occurs, and the clutch is then disabled by the slide. To permit repeated line-spacing, the bell crank is retained by a latch 11, and the slide is thereby prevented from returning. The latch is connected by a rocking arm 15 and link 14 to a feeler-lever 12 which normally enters a slot 16<1> in a stationary plate 16 and prevents co-operation of the latch and bell crank. When the platen-carriage is moved to the extreme left-hand position, the web prevents the feeler-lever from entering the slot, and the latch is permitted to hold the bell crank. Thereafter, the line-spacing mechanism is repeatedly operated to effect blanking, the operation being stopped when one of the perforations 13 registers with the feeler-lever.

Title: Improvements in Graphite Moderators for Nuclear Reactors.
Inventor: LABATON VIVIAN YOMTOB
IPC: G21C5/12
Filed: 1967-01-16
Abstract: 1,176,685. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 6 Dec., 1967 [16 Jan., 1967], No. 2335/67. Heading G6C. In a CO 2 -cooled, graphite-moderated nuclear reactor in which the coolant contains methane as a corrosion inhibitor, the graphite moderator has a mean surface area of less than 0À2 sq.m./gm. (as measured by the B.E.T. adsorption technique). Such a low surface area may be obtained by repeatedly impregnating the graphite or the carbon body from which it is made with carbonaceous material which is then carbonized in the pores of the graphite or carbon body. For a constant methane level, the inhibition factor is a function of the surface area of the graphite-the lower the surface area the better the inhibition.

Abstract: 378,331. Drying clothes &c. KRANTZ, H., [Firm of], Industriestrasse, Aachen, Germany. Feb. 5, 1932, No. 3486. Convention date, Feb. 9, 1931. [Class 34 (ii).] Clothes &c. are dried in cylinders which rotate on their own axes and simultaneously advance in an endless path in a heated closed casing through which air is passed, the arrangement being such that when one cylinder is stopped for reloading the others are kept rotating on their axes. The casing 1 is divided by a partition 2 into two compartments in one of which are a number of cylinders 12 .. 17 rotatably mounted on their axes between two discs 11, 11<1> carried by a hub 10 which is rotated by a shaft 5 and motor 9. The cylinders are contained in separate compartments formed by partitions 19 carrying felt strips 20 which make tight joints with the casing 1 which is provided with a door 21. The shaft 5 is given a step-by-step motion so that when it is at rest there is always one cylinder adjacent the door 21. The cylinders are rotated on their axes by means of an endless chain 23 which is driven by a sprocket 24 rotated by a motor 26, the chain 23 engaging sprockets 22 on the cylinders. The motor 26 can be reversed to reverse the rotation of the cylinders about their axes without affecting their motion about the shaft 5. To stop the rotation of each cylinder as it reaches the door 21 the chain 23 is deflected by a pulley 27 and thus disengaged from the sprocket on the cylinder. The disc 11<1> has openings 28, 29 for the ingress and egress of air which is circulated through the apparatus. The chamber 4 is divided by partitions 30 into a number of compartments containing fans and heaters 31, 36 which circulate hot air from the compartments of the chamber 4 through the compartments containing the cylinders. Drying commences,at the position I, Fig. 3, and continues until the corresponding cylinder arrives at position V when drying is complete and the goods are subjected to cool fresh air to which ozone may be added. At position VI the goods are removed. The fan 35 supplies all the fresh air required by the machine and when finally saturated at the position where drying commences it is discharged through the control flap 43. The door 21 may be provided with a safety device which prevents starting of the motor 9 while the door is open and with a second device which prevents the door being opened until the motor 9 has been stopped and a cylinder has been brought into the proper charging position. In a modification, the cylinders revolve about a vertical axis and in another modification they move in a non- circular path through the various drying stages by endless chains from which they are suspended.
