Filed: 1944-11-22
Abstract: 580,396. Batteries. FULLER, L., and SUDLOW, E. W. Nov. 22, 1944, No. 23254. [Class 53] The plates and porous sheet separators of a storage battery are placed in the container under compression be tween the front and rear walls but they are not o: sufficient width to fill the con tainer, a free space being left at one or both sides as shown at 24, 25 in plan in Fig. 2. The plates and separators form a pack, the porosity of which is at least fifty per cent. and may be constructed as described in Specification No. 561,056. When electrolyte is poured into the cell it flows into the spaces 24, 25 and becomes entirely absorbed into the plates and separators. The pack may stand on the bottom of the container or on a ceramic or other porous slab 23 as shown in Fig. 1 to give the electrolyte access to the bottom of the pack. A porous slab 26 may cover the pack and may support a vent and filling tube 27. The spaces 24, 25 may contain loose material such as glass wool or asbestos fibre and the separators may consist of mats of glass wool impregnated with kieselguhr and rubber latex as described in Specification 537,377, [Group.V].

Title: Improvements in character printing apparatus
Inventor: TURNER FREDERICK JAMES LESLIE
IPC: H04L13/18
Filed: 1964-06-05
Abstract: 1,058,119. Selective printing; typewriters. CREED & CO. Ltd. June 5, 1964, No. 23414/64- Heading B6F. Type-bar machines; typewheel machines ; perforated tape input control.-In an electric typewriter or selective printer in which the printing of data is controlled from a reel of perforated tape T (Fig. 1, not shown), the method of printing comprises reading of the coded characters of said data from said tape in the reverse order from that in which said character was originally perforated so as to obviate the need for rewinding of the tape and printing said characters in the said reverse order. In the embodiment of the apparatus shown in Fig. 7, a typehead 1 prints the last recorded character " 4 " first, in an inverted manner, so that when printing is completed the characters of said data appear on the printing medium in the order in which they were originally applied to the tape (Fig. 6, not shown). In another embodiment (not shown) the typehead may be replaced by type bars. Type-selection mechanism.-The tape has a plurality of code combinations, each code combination being representative of an alphabetic character and a number or a symbol (Fig. 1). To distinguish between a letter and a number code combinations preceding a letter or a number are perforated in the tape, such code combination being necessary only when a change from letters to numbers or vice versa took place. On reading of such a code combination for, e.g., numerals well-known means operate to move the typehead 1, Fig. 4, upward with respect to the printing medium 2 and also to rotate it. Types, dies and printing surfaces.-To effect the reverse printing in Fig. 7, the typehead 1, Fig. 4, has the alpha-numerical and special characters inverted by 180 degrees. Reversible arrangements.-To avoid re-reeling of the tape T (Fig. 1), the tape as perforated is first used for reverse printing in an apparatus having a modified typehead 1, Fig. 4, and for subsequent printing the tape which is now rereeled may be used in a printing apparatus having an ordinary typehead 1 (Figs. 2 and 6, not shown).

Abstract: 1,185,329. Paper making. CLUPAK Inc. 25 May, 1967 [27 Feb., 1967], No. 24438/67. Heading D2A. In a press for the compressive shrinkage of paper, the hard surface on to which the web is pressed has a low frictional drag, so that webs of high water content can be treated. In particular, the water-to-fibre ratio is between 1:1 and 3:1, and the frictional drag is not more than 85% of that between a polished chromium surface and a similar web. Suitable surfaces are: fluorocarbon polymer; metal surface plated with chromium, polished, then etched or pitted, e.g. by sandblasting, and coated with a fluorocarbon polymer (such a surface is still usable when the polymer on the peaks of the metal surface has worn away, leaving metal exposed over a minor proportion of the working surface); metal surface plated with chromium treated or applied to give a surface of small closely spaced convex modules, e.g. by polishing a steel surface, then blasting it and finally plating it. Because of its high water content, the treated sheet may be machine glazed. The shrinking apparatus may be, apart from its coefficient of friction, similar to that of U.S. Patent 2,624,245.

Abstract: 1,246,910. Diapers. JOHNSON & JOHNSON. 16 May, 1969 [16 May, 1968], No. 25029/69. Heading A3V. [Also in Divisions Dl and D2]  A disposable diaper, Figs. 8 and 9, comprises an absorbent pad 31 of wood pulp located between two wider sheets 29, 30 each comprising a bonded non-woven fabric formed of 75-98% cellulosic short fibres having a length of less than 1/4 inch, the remainder being cellulosic long fibres of a length greater than 3/4 inch, and a binder having a viscosity of less than 5 centipoises prior to drying, the fabric having a weight of less than 8 ounces per square yard and a density of 0.15 to 0.05 grams per cubic centimetre. The sheet 30 is longer than the sheet 29 and its extending ends 32, 33 are folded over to form reinforced areas for receiving safety pins. Both the sheets 29, 30 may be absorbent, i.e. contain a rewetting agent, or only the sheet 29 and the pad 31 are absorbent. If desired, the side edges 36, 37 of the pad are secured by spot bonding. The diaper is folded as shown in Fig. 9 and the double folds are held by adhesive 41.  The non-woven fabric is produced by depositing a uniform mixture of the short and long fibres, in a dry condition, on a moving foraminous screen or belt 13, Fig. 1. An excessive amount of binder, e.g. an acrylate or urethane polymer, is flowed onto the web from a dispenser 14. Excess binder is removed by a suction box 15 and the web 10 passes through a heating device 16 to dry the web and cure, without substanital compression of the fibres, the binder which is present in amounts of 1-30% of the weight of the fibres on a dry solids basis. The short fibres may be wood pulp or second cut cotton linters and the long fibres may be synthetic, e.g. rayon. One surface of the fabric may be embossed to improve the drap thereof. A fabric in which the surface fibres on one side have more loft than those on the other may be prepared as above but with a loose weave fabric separating the mixture of fibres into two layers. After passing through the heating device 16, the laminate is split into two layers and the loose weave fabric removed.
