Title: Improvements in or relating to inking mechanism of printing machines
IPC: B41F31/14
Filed: 1931-07-17
Abstract: 381,966. Printing-machines. LINOTYPE & MACHINERY, Ltd., 9, Kingsway, London, and SPENCE, F., Barwick House, Washway Road, Sale, Cheshire. July 17, 1931, No. 20515. [Class 100 (ii).] Inking-apparatus.-In an inking- apparatus in which a messenger roller contacts alternately with a fountain roller and a continuously rotating distributing roller, a driven member is located in such a position as to make driving contact with the messenger roller at a stage during its passage to the distributing roller. As applied to a cylinder machine having a reciprocating bed 7, a messenger roller 2 conveys ink from a fountain roller 1 to the first roller 3 of a set of continuously rotating rollers 3, 3a, 3b, 3c supplying a drum 4 from which the ink is intermittently transferred to a set of forme-inking rollers 5. Arranged in the path of the roller 2 is a roller 8 connected by chain gearing 9, 10, 11 to a shaft 12 carrying a gear 14 connected through gear 15 to a gear 16 connected to a sprocket wheel 17 over which passes an endless chain 18, the upper run of which is attached to a bracket 20 on the bed. Bv this means the roller 8 is driven alternately in opposite directions in accordance with the movements of the bed 7. The roller 2 is carried by levers 21, one of which is connected by a link 23 to a bell-crank lever 24 rocked by a cam 26 and link 25, and the movements are such that the roller 2 in moving from the fountain roller 1 engages with the roller 8 while this roller is at rest at the beginning of the printing stroke of the bed. During the portion of the printing stroke that the bed is moving uniformly, the roller 2 moves into engagement with the roller 3 and back again into contact with the roller 8, where it remains until this roller is again at rest at the end of the printing stroke of the bed.

Abstract: 700,484. Windscreen cleaners. TRICO PRODUCTS CORPORATION. Sept. 5, 1951 [Sept. 20, 1950], No. 20983/51. Class 138 (1) A windscreen wiper blade for flat windscreens comprises a wiper body, a channel assembly in which the top edge of the wiper body is held and of which the centre portion is split or notched to import flexibility to the blade, wherein a guide member loosely embraces the channel assembly and covers the split or notched portion so as to limit the flexibility of the blade, the guide member being unconnected to the wiper arm attachment means and free from contact with the wiper body. The wiper body 9 has an enlarged portion 10, Fig. 4, loosely gripped in two channel members 11, 12, Fig. 3, in order to allow the blade to assume an inclined position as it moves over the windscreen. The guide member 21 slidably fits around the inner ends of the channels 11, 12 and covers the gap 13 there between. The member 21 also permits limited up and down movement of the members 11, 12 therein. Outward movement of the members 11, 12 is limited by the edges of apertures 26, 27 therein engaging tongues 24, 25 depending slightly from cut-out portions 22, 23 in the guide member. The members 11, 12 are limited in their inward movement by abutting one another. Flexing of the body 9 is limited in both upward and downward directions by the inner ends of the members 11, 12 contacting the central portion of the guide member and the members 11, 12 contacting the outer ends of the guide member, respectively. The members 11, 12 are connected with a limited amount of play to the ends of a yoke member (not shown) connectible by a clip to the wiper arm. Stop members are provided on the outer ends of the channels 11, 12 to limit relative sliding movement between the member and the wiper body. Instead of the two part channel assembly 11, 12, a single channel having a notched central portion, providing flexibility, may be used. Specification 700,456 is referred to. Reference has been directed by the Comptroller to Specifications 639,341 and 700,481.
Patent GB-679326-A (GB)
Title: Improvements in or relating to coating compositions
IPC: C09D7/65
Filed: 1950-08-24
Abstract: A coating composition capable of forming films without development of wrinkled surface patterns comprises one or more esters derived from fatty acids having conjugated double bonds as a drying agent and an alkaline earth metal salt of an alkylated-phenol-aldehyde condensation product.  The drying ingredients specified are dehydrated castor oil and alkyd resins, epoxide-group-containing resins and other high molecular compounds, the free hydroxyl groups of which have been esterified with fatty acids which contain or part of which contains conjugated double bonds.  The metal salts, of which calcium and barium are preferred, may be made (1) by heating an equivalent amount of alkaline earth metal hydroxide at 60 DEG  to 110 DEG  C. with the condensation product of an alkyl-phenol and aldehyde; (2) by using alcoholates instead of hydroxides and effecting the reaction under anhydrous conditions in the presence of the alcohol from which the alcoholate is derived, and (3) by condensing the alkyl phenol with the aldehyde in the presence of the hydroxide.  The alkyl phenols used preferably contain a single branched chain alkyl group of 3 to 12 carbon atoms.  The metal salts are preferably used in amount from 0.1 to 2.0 per cent by weight of the drying ester.  In examples: (1) the calcium salt of (a) an octyl-phenol-formaldehyde condensate, (b) tertiary-butyl-phenol-formaldehyde condensate, and (c) koresin, i.e. the reaction product of p-tertiary butyl phenol with acetylene in the presence of zinc naphthenate, are added to a xylene solution of a resin prepared by condensing bis - (4 - hydroxyphenyl) - 2,2 - propane with epichlorhydrin and esterifying the product with dehydrated castor oil acid, to give compositions which are coated on glass panels and baked; (II) the salt (c) of example I is added to a solution of a dehydrated castor oil modified alkyd resin; (III) an enamel contains titania, the drying ester of example I, xylene, petroleum solvent and the metal salt (a) of example I.  Specification 407,997 is referred to.

Filed: 1946-07-16
Abstract: 614,650. Lubricating. WHITAKER, F., and BOUSKILL, H. F. July 16, 1946, No. 21238. [Class 12 (iii)] An internal-combustion engine lubricator wherein oil suspended in air is sucked into the upper portions of the cylinders, comprises an auxiliary container for a predetermined amount of oil, arranged within the vessel of the lubricator so that initially (on the first suction stroke) a body of oil is drawn into the cylinders. A glass vessel 1 contains a coiled tube 12 to which oil can slowly pass through a needle valve arrangement in a block 9 carried by a support tube 7 depending from a cover 2 for the oil vessel. One end 13 of the coiled tube extends above the filled level of the vessel 1 and the other end 14 communicates via a union 15 with a pipe 16 leading to the engine induction pipe. A filling tube 19 provided with a stop plug 22 opens into the top 2. The stop plug 22 has a flat or groove to give a venting passage. On starting the engine the body of oil contained in the coiled tube is sucked into the engine cylinders on the first stroke, the subsequent lubricant entering being controlled by the needle 17 and being carried along by air entering at the top open end of the coiled tube. The lubricator vessel 1 may be filled automatically when the engine is running, lubricant being drawn into the vessel through the tube 19 due to the partial vacuum existing therein.
