Abstract: 1360058 Golf club cover PLASTIC DIP MOULDINGS Ltd 11 Aug 1972 [12 Aug 1971 25 Oct 1971] 37831/71 and 49411/71 Heading A6D [Also in Division B5] A golf club cover comprises a hollow head portion I and a tubular stem 2, integrally moulded of plastics material, the stem being formed with corrugations 4 to permit the club head passing therethrough. The corrugations may extend to the open end of the stem 2 or may stop short thereof. At least a part 6 of the head portion 1 may be transparent or translucent to permit the club head to be seen through the cover or the head may incorporate a club number either by embossing or printing or by the provision of a pocket for a marked disc or by moulding such a disc in the plastics material. The cover is formed by dip moulding using a suitably shaped mould. The mould may be first covered with a fabric sleeve so as to produce a fabric finish on the inside of the cover and the mould can be grooved to produce ribs on the inside of the cover to keep parts thereof from contacting the club head. Parts of the mould can be polished or shot blasted in order to produce transparent or frosted parts, respectively, in the cover, as required. For producing a pocket in the cover head portion (Fig. 6, not shown), the moulding tool is formed with a disc-shaped projection spaced from the rest of the tool but connected thereto by a bridge piece which in effect gives rise to an opening (11) into the pocket.

Abstract: 1442432 Titanium dioxide OCEANIC PROCESS CORP 17 Aug 1973 [29 Aug 1972] 38934/73 Heading C1N TiO 2  is obtained from Ti-containing material by reducing the material with a gas to form lower valence Ti compounds, extracting lower valence Ti with aqueous HCl, separating the extract from the residue, the latter being returned for further reduction and oxidizing lower valent Ti in extract to Ti<SP>IV</SP> and recovering TiO 2 . Reduction may be effected at 900- 1500 C. with H 2 , CO or hydrocarbons, to form Ti 2 O 3  with some TiO and Ti 3 O 5 . Treatment with HCl may be at 95-155 C. and at pressures up to 125 p.s.i. The HCl may contain HF which may be generated by adding CaF 2  to the HCl. The TiCl 3  solution may then be filtered (undissolved residue being recycled), concentrated, oxidized, e.g. with O 2  at 90-160 C., and hydrolysed to precipitate H 2 TiO 3 , which is calcined.

Title: Kitchen equipment unit including a cooker hotplate
Inventor: OATLEY ARTHUR FREDERICK
IPC: F24C15/10
Filed: 1957-12-17
Abstract: 867,237. Supports for articles to be heated; covers; splash screens; drip trays. OATLEY TECHNICAL DEVELOPMENTS Ltd. March 17, 1959 [Dec. 17, 1957 (2)], Nos. 39208/57 and 39209/57. Class 126. A portion at least of the top of a kitchen cabinet forms a cover over a cooker hot plate and can be moved to a substantially vertical position, in which it forms a splashback, to expose the hot plate, of which at least the pan support is adapted to be raised from a storage position below the level of the surrounding working surface to a position of use above this surface. As shown, an arcuate portion 8 of the pan support 7 embraces a bar 9 carried by the cover 4 and parallel to the axis of the cover hinge 6 and in the storage position a track 10 on the undersurface of the support 7 rests on a roller 11 rotatably supported by a pillar 12. When the cover 4 is raised, the rear part of the support is first raised, then the whole support is moved rearwards causing the track 10 to run over the roller 11 until a horizontal part 13 rests on the roller. The hinge arrangement is such that the weight of the support urges the cover open. A drip tray 15 underlies the whole hot plate and the gaps 16 between the edges of the cover and surface 3. In an electric hot plate (not shown) the boiling ring and drip tray move with the pan support, the tray being of sufficient size to underlie the gaps 16 when the cover is closed. Other means of raising the hot plate or merely the pan support actuated by raising the cover include spaced parallel links, toggle links, inclined planes engaged by roller or ball bearings and cams engaging cam followers on the movable part. Similar means may be actuated manually, one connection to the cover being omitted. In a preferred embodiment, a removable pan support only is movable manually from a storage position in which lugs on the sides of the opening in the working surface engage in deep recesses in, or pass right through, the support to a position of use in which the lugs engage in shallower recesses in the support. The location of the lugs and recesses may be reversed. The control taps or switches may be mounted on the front of the cabinet, on a flange on the front of the cover 4 or on a fixed panel above the cover when raised or bordering a recess, into which the raised cover fits, in a back rail which may also support a light or a plate rack foldable behind the rail. Particularly for larger hot plates the cover may be hinged intermediate its length on an axis parallel to that of the hinge 6.

Abstract: 1,173,775. Die-casting machines. DIE CASTING MACHINE TOOLS Ltd., and E. A. R MACE. 6 July, 1967 [6 Sept., 1966]. No. 39738/66. Heading B3F.  In a die-casting machine in which a plunger 11 is initially moved slowly, then accelerated, during its movement to inject molten material 18 into a die cavity 15, means are provided to slow down the speed of the plunger 11 when it is retracted. A valve spool 101, used in the control of speeding up the movement of the plunger in its downward -movement, is attached to a piston 29 and has an enlarged upper portion 104 that passes into a cylinder 110 through a seal 105. In the cylinder is a well 112 having a port 117 that allows an hydraulic oil 111 to enter therein and an adjustable needle valve 116, and the well includes a relatively narrower portion formed by a shoulder 113 in which the upper portion 104 of the valve spool 101 is a slidingly sealing fit. On retraction of the plunger 11 its movement is slowed down when the said portion 104 enters the relatively narrower portion of the well 112 and the oil forced through the restricted opening of the needle valve 116. The arrangement of the diecasting machine is such that the plunger is slowed down just before a port 22 is uncovered by the retracting plunger 11 to prevent molten material 18 being drawn into the goose-neck passage 13 and spilling into the die part 16 when the die parts 16, 17 are separated.

Abstract: 1,042,399. Endless belt conveyers. M. G. DE SAN. Sept. 28, 1964, No. 39381/64. Heading B8A. An appliance for feeding tea from a trough 8 to a take away conveyer 23, Fig. 3 (not shown), comprises an endless pick-up belt 2, perforated or porous, mounted on a support articulated to a frame 10 so as to permit a variable in clination of the belt and a suction fan 22 actuable so as to exert a sucking action over part of the belt 2. The belt 2 which may be a woven fabric or perforated plastic is mounted on drums 3 supported between side plates which form an enclosure 6 with the belt. One of the drums 3 is driven and the drum at the tea receiving end 14 of the belt is perforated to allow the suction to be applied at the belt surface at this end. The suction area is limited by a blanking plate 15 within the enclosure 6. The belt and support are pivoted at 9 to the frame 10 and are counter-balanced by adjustable weight 11 or springs, such that the end 14 of the belt rests lightly on the tea 7 in the trough 8. The frame 10 on rail wheels 18 is movable along the length of the trough and carries a further conveyer 20 transverse to the pick-up belt 2. Several of these appliances may be used, all the conveyers 20 of which supply tea to a common conveyer 23, Fig. 3 (not shown). In a further embodiment the belt 2 is replaced by a perforated drum rotatable about its own axis and eccentrically pivoted on a frame.
