Patent GB-481900-A (GB)
Abstract: 481,900. Cash registers. NATIONAL CASH REGISTER CO. Sept. 21, 1936, No. 25594. Convention date, Sept. 21, 1935. [Class 106 (i)] [Also in Group XVI] Printing on inserted material.-In a cash register or similar accounting-machine having means for simultaneously printing upon a ledger card and pass-book, the mechanism is a rod 42 to the left to block all the printing hammers for the pass-book. During this operation, the type-wheel 19 for the ledger card prints the letters " OB " in alignment with the transaction as shown in Fig. 1. At some future time when the pass-book is present, the operation is repeated with the control lever displaced two steps above the add position, in which position the pass-book hammers adjustable to print special marks upon the ledger card to indicate that a corresponding pass-book print has not been effected, and to indicate that the delayed corresponding print has been made in the pass-book. The machine has two identical sets of type-wheels, Fig. 6, with the undersides of which co-operate hammers 24 for impressing the ledger card and pass-book, respectively. Each set of type-wheels is divided into groups for the amount, account number, &c. and includes one wheel 19 set by the usual control lever 20 and adapted to record the nature of the operation performed. The pairs of hammers for corresponding groups in the two sets are each operated by a link 28 given a constant left- and-right excursion by a cam 35 during each operation. In an operation for which the pass-book is not available, the control lever is adjusted to the first position above the add position and, through the linkage shown, rocks are freed but all the ledger-card hammers, with the exception of that for the type-wheel 19, are blocked by a rod 60. During this operation, the type-wheels 19 print a dash on both the ledger card and the pass-book as shown in Figs. 2 and 3, respectively, the dash on the ledger card serving to cancel the '' OB " previously printed and thus indicate that the transaction has been completely entered

Abstract: 1445145 Casting processes; making moulds GENERAL MOTORS CORP 25 Oct 1973 [7 Nov 1972] 49722/73 Headings B3F and B3A A method of forming thin-sectioned castings, e.g. battery grids 20 made from an alloy comprising 3% Sb, 0À3% Sn, 0À1% As balance Pb, comprises providing a die 2 having a porous metal body 6 having thereon an impervious layer 8 provided with openings leading to a die cavity 4 in said body, passing a cooling gas through the porous body and out through the walls of the cavity, immersing the die into molten metal to fill the cavity with melt, removing the die from the metal and shedding any melt metal from the outer surface of the layer, and stripping the casting from the cavity. In the embodiment shown, the porous body 6 is provided with channels 10 which may be connected to a source of vacuum or compressed air. Before immersion of the die in the melt, the layer 8 is heated to a temperature at which the melt metal is readily shed from the outer surface of the layer 8 after removal of the die from the melt, and cooling air is passed through the channels 10 and out through the walls of the cavities 4. The die is then immersed in the melt, which may be maintained at a temperature of 650 F., and a vacuum optionally applied to the channels 10 to suck the melt into the cavities 4. The die is then removed from the melt and the castings ejected by again connecting the channels 10 to the source of compressed air. In another embodiment, the die is in the form of a rotatable drum having a stationary air pressure chamber (37) and a stationary vacuum chamber (38) and is as described in Specification No. 1,445,145 except that the die cavities may be interconnected to produce a continuous strip of castings, Fig. 8 (not shown). The porous body 6 may be formed of sintered stainless steel or brass and the layer 8 may be of stainless steel, Cu, Cr, Fe-Ni alloy, metal oxides, carbon or cork and may be applied to the body 6 by electroforming or flame or plasma spraying. When both the body 6 and layer 8 are of stainless steel, the layer 8 may be formed by grinding a sintered body in manner which causes the particles on the surface to flow together and seal off the pores. A grid pattern is then mechanically cut through the layer 8 and the die cavity is formed in the body 6 by electro-chemical machining, chemical milling, electrical discharge machining or photoetching. The outer surface of the layer 8 may be provided with a plurality of grooves at a density of about sixteen per inch.

Title: Warp tension controller
IPC: D03D49/06
Filed: 1975-12-15
Abstract: In the warp-tension controller in the form of a PI controller with an operational amplifier (4) which controls the warp-beam drive and the feedback circuit of which contains an integrating capacitor (8) in parallel with a resistor (6), immediately after the loom has been switched off one pole of the integrating capacitor (8) is separated from the output of the amplifier (4) and is changed over to the output (10) of a voltage store. The output voltage of the voltage store is kept constant at a value which the output voltage of the amplifier (4) had immediately before the loom was switched off. As soon as the loom is switched off, the output voltage of the amplifier (4) can therefore fluctuate unrestrictedly, without this having an effect on the voltage across the integrating capacitor (8). Normal operation is consequently possible immediately after the loom has been switched on again. <IMAGE>

Abstract: A process for the purification of high molecular weight polyolefines obtained by polymerization using a catalyst comprising an organometallic compound and a transition metal compound, characterized in that after decomposition of the catalyst complex with alcohols, impurities are removed from the polyolefine by washing with a mixture of an aqueous solution of a non-ionic surface-active agent and a complex-forming agent in the presence of non-polar or weakly polar solvents, whereafter the polyolefine is separated from the wash medium until the disappearance of the surface-active agent from the washing water, and then the polyvalent salt solution of the complex-forming agent is extracted from the polymer with a non-polar or weakly polar solvent.  The complex forming agent may be selected from water-soluble salts of phosphoric acids including phosphates, pyrophosphates and polymeric phosphates and aminopolycarboxylic acids or salts thereof, for example the sodium salt of ethylene-diamine-tetra-acetic acid or nitrilotriacetic acid.  In the example, polyethylene or polypropylene are treated with an alcohol and then purified by washing with a mixutre of water, the sodium salt of ethylene-diaminetetra-acetic acid and octylphenol condensed with ethylene oxide at a pH of 9 to 11, followed by washing out with soft water until the surfaceactive agent disappers from the washing water.
