Abstract: 456,785. Coin-freed game apparatus. BRYAN, W. E., Bryan's Automatic Works, London Road, Kegworth, Derby. Oct. 16, 1935, No. 28527. [Class 27] In amusement machines comprising a coin or check freed mechanism and a pay-out mechanism, the payout mechanism is associated with a hopper for coins, checks, &c. and a container for prizes in kind so that said mechanism can act to deliver coins &c. and prizes in kind, means being provided to prevent at will either the coins &c. or the prizes in kind from being delivered. As applied to a game in which three balls are projected by a lever f, Fig. 2, between glass panels c, d to drop into three pockets g and tilt levers g<1> to release a lever k<1>, Fig. 3, which is rocked by springs k<2> to cause a slide k<4> on its lower end to deliver a prize, the prize may consist of coins &c. in a hopper j or prizes in kind in a container l. The slide k<4> works over a support k<6>, Fig. 5, and has a slot k<5> which receives a number of coins &c. from the hopperj. These are carried, when the lever k<1> is released, over a slot k' in the support k<6> and pass to a delivery tray. The slide k<4> may also push out a prize in kind from the container l. Slots j<2>, l<2> are provided respectively in the hopper and container to receive a bar which prevents the coins &c. or the articles from passing down into the path of the delivery slide. By this means one or other of the containers j, l is put out of action ; the slide k<4> is shown in Fig. 5 as acting to deliver prizes in kind only. After insertion of a coin and rotation of a knob, a plate h<4> carried by a shaft h<3> is swung aside to allow the levers g<1> to tilt further and the balls to drop to a ball receiving member from which they are delivered one at a time for play by rotating the knob. The plate h<4> is also moved aside to release the balls when the pay-out mechanism is actuated by a pivoted device m. Coin action, mechanical-connection.-A coin drops to a position between the end of a lever h<1> and a crank pin h<2> on the shaft h<3>. When the outside knob is rotated, it rocks the lever h<1> through a linkage i<1>, i<2>, thereby depressing the coin and rocking the shaft h<3> and plate h<4>. The coin continues down the coin shoot to the container j.

Filed: 1928-10-10
Abstract: 302,887. Meisenbach, Riff arth, & Co. Akt.-Ges. Dec. 23. 1927, [Convention date]. Photo-mechanical printing-surfaces; retouching.-To obtain screen positives with corrected colour-values, particularly for offset printing, a collodion emulsion or wet plate is used which is treated with a solution of a hygroscopic substance, such as glycerin, so that partial etching can be effected whilst the plate is in a moist condition. Varnish can be applied to the moist plate, where no etching is required, and subsequently removed by benzine. Repeated corrections can be made if necessary after drying by again rendering the plate moist with the glycerine. The use of iodine, cyanogen, and sodium hydroxide is specified. To obtain a flexible film from the screen-positive or from a negative made therefrom, the positive or negative is covered with a rubber solution, and the image pellicle is separated and mounted on celluloid by acetic acid in the usual manner.

Title: Digital Filters.
IPC: H03H17/06
Filed: 1968-06-20
Abstract: 1,159,909. Digital filters. INTERNATIONAL BUSINESS MACHINES CORP. 20 June, 1968 [19 July, 1967], No. 29365/68. Heading H3T. In a digital filter, the multiplication circuits are arranged to multiply the input signals by binary numbers containing both positive and negative bits. In a " post-multiply " circuit, each multiplier 202, 204, 206, 208 comprises two submultipliers, e.g. 210, 211 which multiply by positive and negative bits respectively. The positive and negative signals are then separately summed in adders 218, 219 and then combined in a third adder 220. By using positive and negative bits, any number can be expressed without using two consecutive " 1 " bits. This increases the multiplication speed by decreasing the number of shift-and-add operations. A further reduction may be obtained by premultiplying the input signal by a suitable coefficient, and then multiplying the output by its reciprocal, Fig. 3 (not shown). The invention may also be applied to " pre-multiply " filters, Fig. 4 (not shown).

Title: Improvements in or relating to the washing and cleaning of textiles and other fibrous materials
IPC: C11D1/22
Filed: 1935-10-25
Abstract: Processes for the treatment of textiles, leather and other fibrous materials are conducted with or in the presence of soluble salts of the sulphonation products of hydroaromatic alcohols obtained by the hydrogenation of aromatic hydroxy compounds which have at least one aliphatic residue containing at least six carbon atoms attached to the nucleus.  The hydroaromatic alcohols may be obtained from aromatic hydroxy compounds such as phenols, cresols, naphthols and benzenehydroxyquinolines by condensation with higher olefines or primary, secondary or tertiary alcohols with subsequent catalytic hydrogenation. Sulphuric, phosphoric and perchloric acids, zinc and aluminium chlorides, bleaching earths and boron fluoride may be used to assist the condensation.  The hydroaromatic alcohols may also be prepared by esterifying the aromatic hydroxy compounds with higher fatty acids and hydrogenating the hydroxy ketones which result on heating with aluminium chloride.  For the sulphonation, the usual sulphonating agents may be used and the products may be neutralized with alkalies or organic bases such as triethanolamine, aminopropandiol and tetraethylammonium hydroxide.  The products are cleansing and protecting agents and in some cases foaming agents, which may be used in association with alkali carbonate or other salt, alkali ortho, meta, pyro, hypo and meta phosphates, alkali silicates and borates, sodium and magnesium phosphate, sodium naphthalenesulphonate and the corresponding propyl and butyl derivatives, percompounds, soaps, sodium oleylmethyltaurin, benzine, benzene, lower and higher alcohols, cyclohexanone, glycolmonoethylether, glyceroldimethylether, glycerolmonocyclohexylether, pentamethylene, wool fat, urease, pancreatin, phenols and p-chlor-m-cresol.  In examples, the following aromatic hydroxy compounds are hydrogenated and then sulphonated: o-cresol substituted by residues of cracked benzine or a hydrocarbon mixture obtained from carbon monoxide and hydrogen, n-heptyl-o-cresylketone and 4-sec.-octylphenol.  Specifications 443,487 and 455,086 are referred to.
