Title: Two-colour ball-point writing instrument
IPC: B43K24/16
Filed: 1964-09-10
Abstract: 1,022,608. Multiple retractable ball-point pens. TERMOPLASTIC S.r.l. Sept. 10, 1964 [Sept. 25, 1963; Feb. 24, 1964], No. 37140/64. Heading B6P. In a multiple retractable ball-point pen having an individual rear actuated push-button 8 or 9 for each ball-point cartridge 3 and 4, Figs. 1 to 3, two elastically deformable detents 7c are positioned in the diametral plane of the rear casing 2 of the pen. Each detent 7c is formed on an upright arm 7b of a member 7 of synthetic plastics material housed within the rear casing 2. On the flat face of each pushbutton a projection 10 is. formed having a top flat surface 10a and a bottom wedge portion 10b. The arrangement is such that with one button in the projected position with the detents 7c engaging the top flat surface 10a, when the other push-button is actuated, whether to the full projected position or only part of the way, the wedge portion 10b of the projection 10 forces the detents apart and releases the projected push-button. The pushbuttons 8 and 9 are prevented from slipping out from the rear of the pen by shoulders 2b on a dividing wall 2a of the casing 2 and by two projections 12, 13 on the semi-circular outer faces of the push-buttons which co-operate with semi-annular projections on the casing 2. In a modification, Figs. 5, 8 and 10 (not shown), the member 7 is replaced by a separating member 16, Fig. 8, which is screw-threaded into a single casing 14, Fig. 5. Each push-button 30, Fig. 10, has a projection 31 which co-operates with detents 18 and 19, and two projections 33 which slide in grooves 25, 26 formed in the separating member 16. Operation is identical with that described above. The push-buttons 30 are prevented from slipping from the rear of the pen by the end faces of the three projections 31 and 33 engaging abutments 22, 23 and 24. In a modification of the embodiment of Fig. 5, the separating member 16, instead of being screw-threaded into the casing 14, is slidingly engaged in the casing 14 with a catch 45, Figs. 12 to 14 (not shown), engaging a perforation or recess in the wall of the casing 14. In an alternative embodiment, Figs. 17 and 20 to 22 (not shown), the push-buttons are replaced by actuating members 50 which have extensions 51 protruding through longitudinal slots 47, 48 in the metal pen casing. The flat faces of the actuating members each have a projection 52 and a recess 55 and tongue 56 for engaging the rear end of a ball-point cartridge. A separating member 60, Fig. 20, has two elastically deformable detents 67 and 68 which co-operate with the projections 52 on the actuating members in a manner similar with that described above. Two radial projections 65 on the separating member 60, serve to retain the member 60 in the casing of the pen by engaging two notches 47a, 48a, Fig. 23 (not shown), formed at the top of the diametrically opposed slits 47 and 48. A metal cap 58, provided with a pocket clip 59, Fig. 15 (not shown), is forced on to the rear of the pen casing and abuts the extension 66 of the member 60.

Title: Improvements in freezing trays
IPC: F25C1/24
Filed: 1938-12-21
Abstract: 522,961. Ice-making. GENERAL MOTORS CORPORATION. Dec. 21, 1938, No. 37153. Convention date, Dec. 27, 1937. [Class 29] A freezing tray grid has a longitudinal division wall comprising relatively movable upper and lower wall sections 16, 17 upon which are mounted transverse walls 30, an actuating lever 18 on the upper section being adapted to react against the lower section to force a relative separating movement between the sections and also operable to effect a lateral twisting distortion of the upper section. The metal longitudinal division wall comprising two plates 16, 17 has slots 33, 34 in which are mounted flexible rubber transverse walls 30. The upper plate 16 is resilient and carries by a pivot 19 a hand lever 18 embracing one end of the plate and having cam surfaces 25, 21. When the hand lever is swung upwardly the cam 25 engages the lip 11 of the pan 10 and forces the pan loose from the ice. Cams 21 then engage surfaces 22 on the lower plate 17 to loosen and tilt the plate 16 upwardly, and when the hand lever reaches a vertical position cam 25 engages the surfaces 22 to lift the plate 16 partly out of its groove in the ice. The lever 18 is then swung laterally and the plate 16 thus twisted to split the ice cubes off the lower plate 17 and crack them at the parts below the plate 17. The notches 33 for the rubber walls 30 decrease in depth towards the end of the plate 16 to which the lever is pivoted and the rubber wall 31 nearest the lever engages a notch 36 in the lower plate 17 to avoid weakening the upper plate at this point. The plate 17 may extend to the bottom of the tray. The surfaces 22 engaged by the cam 21 comprise plates 23 riveted or welded to the lower plate 17. The lower plate 17 may be of anodised aluminium having a wax treated surface. Specification 515,262 is referred to.

Title: Improvements in or relating to nonwoven fabrics and the method of manufacture thereof
Inventor: MEACOCK GRAHAM WALTER
IPC: D04H1/06
Filed: 1963-09-24
Abstract: A non-woven fabric comprises a web, the fibres in which are bonded together by crimping flock, the length of the uncrimped flock fibres being not more than 1/4 inch, and the crimp frequency not less than 20 per inch.  The flock fibres may be heterofilaments in which one component is potentially adhesive. The fibrous web is laid on a working top of a flocking unit, below a flock container and an electric field is applied between the working top and container; flock falls into the electric field and is projected into the web in a direction substantially perpendicular to the plane of the web.  The web is rolled to press the flock fibres into the web, and then treated by a vacuum extractor to remove loose fibres.  The flock fibres are then crimped, by immersing the web in boiling water, dry heating, steam heating or chemically treating the web, to bond the fibres together.  The term "bond" includes fibre entanglement, bonding by fusion and bonding by chemical adhesion.  The flocked web may be needle punched before the bonding treatment.

Abstract: 1406506 Producing alcoholic beverages; ageing wine P BERDELLE-HILGE 16 Aug 1972 [23 Aug 1971] 38197/72 Heading C6E A process for the continuous rapid production of an alcoholic beverage, such as beer or wine, comprises continuously passing a fermentable liquid substrate under hydraulic pressure through at least one reaction bed comprising enzymeproducing micro-organisms maintained in fixed position on a retaining filter whereby the liquid is fermented in a short contact time (i.e. a few minutes) to produce alcohol, and then through the filter, and substantially reducing temporary unintentional variations in the pH of the fermented substrate, and in the fermentation rate, by varying the hydraulic pressure applied to the substrate and/or the temperature of the substrate, and/or by adding yeast to the substrate supplied. Thus, when the substrate is a wort or must and the reaction bed contains yeast, (a) a temporary decrease in the pH of the fermented substrate may be reduced by decreasing the pressure and/or by increasing the temperature of the substrate supplied or (b) a temporary increase in the pH of the fermented substrate may be reduced by increasing the pressure and/or decreasing the temperature of the substrate and/or by adding yeast to the substrate supplied. In the case of beer, the process may be conducted to maintain the pH at about 4.4. The process may be single-stage or multistage and, in the latter case, two or more steps may be used in which different controls are effected, while after treatments of the fermented liquid with micro-organisms may be conducted in a similar manner. Thus, for example, in the case of wine, the fermented liquid may be subjected to treatment with bacteria or yeasts (i) to promote degradation of malic acid and thereby mature the wine, or (ii) to increase the acidity of the wine.

Abstract: 861,306. Wire and other woven fabrics; selvedges. NEW YORK WIRE CLOTH CO. Dec. 16, 1957, No. 39040/57. Classes 142(2) and 142(4) Selvedges, Fig. 23. A fabric woven from wire or other filaments capable of retaining the shape to which they have been bent has the weft ends 40 tucked in and has the two end warp filaments 420, 422 (which may be thinner than the others) disposed close together. Mechanism, Fig. 4. A block 56, movable fore- and-aft of the loom, houses a tucking blade 72 which is movable transversely of the loom against the action of a spring 82. The tucking blade has a groove 75 along its end, continuing as a groove 75a in its rear edge. The fabric is supported on its upper and lower surfaces by a slot 70 in the block 56. As the slay beats up the weft, it pushes the block 56 forward so that the end of the weft projecting from the shed does not touch the tucking blade 72. As the slay recedes after the shed has changed, springs 66 move the block 56 rearwards, whereby the weft is engaged by the groove 75a and is bent until it lies in the groove 75; a ramp 80 carried by the slay then moves the tucking blade endwise as shown to bend the weft end 40 into the fresh shed; completion of the bending is effected by the reed as it beats up the next weft. The ramp 80 is yieldably mounted so that on the forward movement of the slay it rides idly past the tucking blade. In another embodiment, the tucking blade is carried by a pair of short links pivoted at fixed points, so that its rearward and inward movements are combined into an arcuate movement from a position forward of the fell to the position shown in Fig. 4.
