Title: Improvements in coin-freed mechanism
IPC: G07F5/04
Filed: 1940-07-17
Abstract: 541,223. Coin-free apparatus. HARPER, P. S., and HARPER AUTOMATIC MACHINE MANUFACTURING CO., Ltd. July 17, 1940, No. 11812. [Class 27] Coin-action, multiple coin.- Mechanism for varying the number of coins necessary to operate a coinfreed machine comprises a stacking shoot, formed by ribs 4 and the wall of the casing 1, for retaining one or more coins C<SP>1</SP>, C<SP>2</SP> supported by a movable stop 6 adjustable to various elevations in the shoot, the top coin C<SP>1</SP> in the stacking shoot serving to deflect the next coin C<SP>3</SP> into a branch shoot leading to the coin-freed mechanism, this coin C<SP>3</SP> striking a member 8 in the branch shoot to move the stop 6 and release the coin or coins held thereby. In the construction shown the stop 6 comprises a lever pivoted at 7 and having a long arm 8 and a head 10 preferably curved from the pivot 7 as centre, so that there is no upward movement of the coin C<SP>1</SP> when the lever is rotated by the coin C<SP>3</SP>. The movement of the lever is limited by a pin 11 thereon working in a slot 12. The number of coins which lodge in the stacking shoot is determined by the position of the lever, as its pivot pin can be inserted in any one of a number of holes 7a. If the machine is to be operated by a single coin the mouth of the stacking shoot can be closed by a bar 13 having pins inserted in holes 15. When not required the bar can be placed at 13 in the machine. In a modification, instead of shifting the lever to vary the number of coins required, a series of levers mounted on the pivots 7, 7a may be used, all the levers except the one in use being held out of the way by any suitable means.

Patent GB-802469-A (GB)
Title: Improvements in or relating to cellulose ethers
IPC: C08B11/20
Filed: 1957-04-16
Abstract: Water - soluble cellulose ethers, including ethers which are soluble only in aqueous solutions of caustic alkali, are treated with an alkali metal borohydride, preferably at a pH of 7 or above, whereby their stability is improved.  The treatment may be carried out with the cellulose ether in solution and the resulting substance isolated as a solid, e.g. by acidification, salting out or evaporation, or by the addition of a water-miscible organic substance which is a non-solvent for the cellulose ether. Alternatively the treatment may be carried out on the said cellulose ether.  The cellulose ether may be suspended in a liquid in which the borohydride is completely or at least partly soluble but which does not dissolve the cellulose ether, e.g. an alcohol, such as methanol, ethanol or isopropanol, an alkylamine, ethylenediamine, pyridine, morpholine, dioxane, tetrahydrofuran, diethylene glycol dimethyl ether or triethyleneglycol dimethyl ether.  If the cellulose ether is soluble only in aqueous alkali the suspension medium may be water, and if the cellulose ether is soluble in cold water but insoluble in hot water, the suspension medium may be hot water.  Treatment in the solid state may also be effected by adding to the dry cellulose ether a small amount of borohydride solution which is absorbed without the ether losing its solid structure.  From 0.001 to 20 per cent of alkali metal borohydride, based on the weight of cellulose ether, is preferably used.

Abstract: 1,025,486. Packaging-machines. IVERSLEE CO. April 1, 1963, No. 12772/63. Heading B8C. In a machine for making packages by forming recesses in two strips of ductile material, bringing corresponding recesses together to form compartments and sealing the strips over an area partially surrounding each compartment, the non-adherent areas of the strips are spread apart and a filling opening formed in each compartment. Strips 1 and 2 of material e.g. thermoplastically coated aluminium are fed intermittently from rolls C via lubricating brushes H to die mechanisms E where recesses 6 are formed therein by reciprocating heads K. The recessed strips are then fed to heated sealing rolls F, rotated intermittently by a pawl-and-ratchet mechanism and held in yielding contact by springs pressing against their bearings, where they are sealed together over the zones shown shaded in Fig. 3 to produce partially closed compartments. The non- adherent areas are spread apart at their edges by a chisel-shaped spreader 39, and the compartments have filling openings formed therein by an oscillating forming pin 44, connected to operate in timed relation with the rolls F. A filling nozzle is inserted via the filling opening into each compartment, and when this has been filled the nozzle is withdrawn and the spreadapart edges of the strips pass between crimping jaws to seal them together and so close the compartment. To facilitate opening of the closed compartments notches and slots may be formed in the strips between them, and an edge of one strip may overlap the corresponding edge of the other.
