Filed: 1923-05-26
Abstract: 220,729. Woodhouse, A. E., and Owen, J. P. May 26, 1923. Cards, dealing and shuffling. - A device for shuffling, dealing or delivering playing cards, comprises a card container having fixed bottom, rear and side walls, and being divided by one or more transverse partitions or rows of pins into compartments adapted to receive parts of a divided pack of cards, the device being provided with means to exert sufficient frictional retardation edgewise upon all the cards to enable them effectively to be projected in a forward direction one at a time. As shown in Fig. 1, the pack is divided by sliding half of it over a partition c, and the cards are dealt by sliding them singly by hand over an inclined surface f covered with plush, cork or other material which provides sufficient friction to retain the lower cards. The partition c may be adjustable in height. The pack may be shuffled by pressing its edge on a series of notches d thus displacing various parts of the pack to permit of withdrawal and rearrangement of the projecting cards. In a modification, Fig. 5, instead of using an inclined friction surface, the friction is applied to the side edges of the cards by means of cylindrical pads g of cork, rubber &c. pressed against the cards by springs h. In a further modification the pads are of rectangular shape and the outer pads are mounted on blade springs. In further modifications the device comprises one compartment only.

Title: Method of and means for producing mouldings of plastic material
IPC: B32B27/00
Filed: 1942-10-07
Abstract: Fibre is deposited on an accretion mould having the shape of the article to be produced, dried, treated with thermosetting or other binding agent, and placed between dies which are sealed against entry of pressure medium as by being enclosed in a rubber bag.  The whole is then subjected to fluid pressure, with or without heat.  The fluid pressure medium may be steam or water. The water may be contained in a pressure tank, or a lake or the sea may be used.  The accreted article may be reinforced, while still on its mould, prior to treatment with the binding agent, by applying shields to those parts which are not to be reinforced and then dipping the article into the accretion tank a second time; the shields may be automatically applied to and removed from the article.  Alternatively, the reinforcements may be made first and the main part afterwards.  By dipping the mould in different tanks, laminations of differing strength, texture or colour may be obtained.  A thick article may be obtained by making a first accreted lamination, placing it in a mould slightly larger than the lamination, expanding the lamination to the size of the mould, inserting a second accreted lamination into the first, expanding the second lamination, and so on.  Inserts may be embedded in the article during the accretion process, or may be sandwiched between the laminations, or fused on to the blank during the curing process.  If part of the curing mould is made of rubber which is liable to stick to the article being moulded, thin metal foil may be placed there-between, or that part of the article which will come into contact with the rubber is not treated with binding agent.  The mould may be made of sheet metal or metal foil.  Air from the article being moulded may escape through vents in the mould to a receiver.

Abstract: 239,308. Mavor & Coulson, Ltd., and Mavor, J. B. June 18, 1924. Ratchet gearing.-In frictional or positive feed mechanism, such for example as the reversible gear described in Specification 228,329 for slueing the cutter member in coal-cutting machines, or for haulage purposes, forward and reverse friction detents D, D<1> for engagement with the feed wheel B carry pins 8, on which are adapted to bear the heads of rods 2 under the influence of compression springs F. The rods pass with freedom through slots in the framing 5 so that they may be manipulated to bring lugs 9 on the rods behind lugs 10 on the framing and raise the rod heads from contact with the detents. When a lug 9 is disengaged from its lug 10, for instance by one of a pair of levers G actuated alternately by the coal cutter member at each end of its travel, the spring F causes engagement between the rod head and its detent, and the detent is disengaged from the wheel B immediately the drive restarts and relieves the jamming action on the detent. The wheel B is thus constantly oscillated by the driving-pawl and the load, and no feed takes place. Spring-actuated bell-crank letters may replace the rods, or, in a further modification, arms on the detents may be actuated by springs which are either released or compressed to bear upon the arms. A single rod with a T-head acting on both detents may replace the two rods shown in the Figure.

Title: Process for the acetylation of regenerated cellulose fibres while retaining the fibre structure
IPC: C08B3/06
Filed: 1959-04-30
Abstract: Cellulose triacetate fibres are made by displacing the water from water-swollen fibres of particularly reactive dressing-free regenerated cellulose fibres by means of glacial acetic acid, activating the fibres by a treatment at room temperature with glacial acetic acid containing acetic anhydride, in such amount that any trace of water present in the fibres is removed, and also perchloric acid in amount at most 0,2% of the dry weight of the cellulose, removing excess activating liquid, and acetylating the fibres for at most 6 hours at 10 DEG -25 DEG C. by means of an acetylating liquid consisting essentially of 1500-3000% of carbon tetrachloride, 300-500% of acetic anhydride and 0,1-0,5% of perchloric acid, all based on the dry weight of the cellulose. Particularly reactive fibres are defined as those which, on acetylation under the above conditions, give a triacetate (i.e. an acetate of acetic acid content 60% or more) after an acetylation period of up to 6 hours, and suffer a degradation in strength standard (Cm) of less than 30% and a degradation in average degree of polymerization (DP) of less than 40%.  Cm is defined as Tw x Ew where Tw= wet breaking strength in g./denier and Ew=wet elongation at break in per cent.  DP is determined viscometrically, either directly in chloroform or, after saponification, in a cupric ethylenediamine solution.  The regenerated cellulose fibres preferably have a skin to core ratio of at most 60%, and may be in the primary state of swelling, or may have been air dried and then reswollen in water for at least 6 hours before being treated with the acetic acid to displace the water. Fibres so made and textile materials made therefrom show properties similar to cellulose triacetate spun from solution. They can be heat-set, show good crease resistance, thermal stability and low swelling values in water, and have a pleasing handle.
