Abstract: 1,266,567. Coating paper. SCHOLTENHONIG RESEARCH N.V.; SOC. ANON CUATRECASAS and R. GINESTET. 23 April, 1970 [24 April, 1969], No. 20883/69. Heading B2E. [Also in Divisions C3 and D2] A sizing composition comprising modified (thin boiling) starch, a vinyl ester of an organic carboxylic acid having at least 7 carbon atoms, and optionally containing rosin, modified rosin, polyvinyl alcohol, urea-formaldehyde or melamine-formaldehyde precondensate, or polyepoxide, may be employed for the internal sizing of paper by addition to an aqueous pulp slurry, and for the surface sizing and pigment coating of formed paper. The vinyl ester typically amounts to between 0.5 and 20 parts per 100 parts by weight of starch. Examples are directed to: (1) spraying an alcoholic solution of the vinyl ester of a proprietary mixture of highly branched synthetic organic carboxylic acids with 9 to 11 (optionally 9 to 19) carbon atoms on to tapioca starch rendered thin boiling by treatment in aqueous alkaline suspension with sodium hypochlorite. After evaporation of the alcohol, the sizing composition is cooked in water, diluted to a concentration of 5% and used to surface size a base paper which had been slightly internally sized with rosin size. (2) waterleaf handsheets of bleached sulphite pulp are sized with an aqueous composition comprising corn starch degraded by treatment with hydrochloric acid, the mixed vinyl esters mentioned in (1) above, and rosin fortified by addition of maleic anhydride. (3) wood-free paper is sized with an aqueous composition comprising thin-boiling corn starch, vinyl 2-ethylhexoate and modified rosin obtained by heating rosin with 5% maleic anhydride at 185-195‹C and thereafter with 10% of the reaction product of epichlorohydrin and diphenylol propane. (4) a cold swelling starch product made by drying on heated cylinders a suspension of oxidized corn starch in water containing emulsified therein the mixed vinyl esters previously mentioned, rosin modified with acrylic acid and partially neutralised, and polyvinyl alcohol. (5) offset paper is sized with a composition including oxidized corn starch, the vinyl esters of a proprietary mixture of highly branched synthetic organic carboxylic acids with 9 carbon atoms, melamine-formaldehyde resin, polyvinyl alcohol and p-toluene sulphonic acid. (6) a coating slip for pigment coating paper is made of the sizing composition given in (5) above, oxidized starch, china clay and water. The vinyl esters of benzoic, lauric and stearic acids are also mentioned.

Abstract: 1288374 Valves TRIANGLE VALVE CO Ltd 15 Sept 1969 [24 Sept 1968] 4212/71 Divided out of 1288373 Heading F2V  Preventing ingress of foreign matter into the space between a floating annular seating ring 16 or 17 and its corresponding recess 18, is achieved by forming the ring with an annular axial projection 25 which can co-operate with an annular portion 26 of the ring recess 18, the annular portion 26 leading to a conical portion. When used with a gate valve (Figs. 1 and 4, not shown), a portion of the recess 18 is formed with an arcuate radial projection 21 which is disposed at a location remote from the gate-receiving recess such that in the valve open position, each seating ring is retained in position by the action of projection 21 and, diametrically opposed thereto, by the presence between the rings of a terminal portion of the gate. With the gate fully retracted from the valve, the seating rings can be readily removed. Each seating ring 16 and 17 is biased by springs (not shown) towards the recess within which the gate moves.

As shown the magnet 25 is carried by a pivoted lever 23 which is torqued through a coiled measuring spring 22 to which rotary tension is applied by a clockwork motor 4 driving the central shaft through gears 5..10. In operation with the motor wound up the drive is restrained by a pin 12 (on the magnet carrying lever) engaging a toothed brake-wheel 11, until the device is placed on the work thus raising the magnet slightly to the level of the bottom of the housing, (not shown). When the magnet 25 pulls-off the lever 23 rotates so that blade spring 13 engages the brake-wheel 11. (An upper magnet 32 serves to hold the test magnet 25 in the "off" position). If the motor 4 cannot effect pull-off a supplementary spring 28 can be tensioned by a handwheel 26 to apply force through lever 29 which has a pin- and-slot engagement with the magnet carrying lever 23 to provide additional drive.

Nipple 27 communicates with a chamber 23 of diaphragm 9 which is connected by a passage 25 to a chamber 22 of diaphragm 18, so that vacuum at nipple 27 unseats diaphragm 9 from seat 32 and so opens duct 11 to vacuum line 1 and also unseats diaphragm 18 to open duct 12 to ambient pressure port 30. Simultaneous application of pressure to nipple 28 acts on diaphragms 10, 17 which are seated and close duct 12 to vacuum line 1 and duct 11 to atmosphere via port 19. Application of pressure and vacuum to nipples 27, 28 causes vacuum to be applied to duct 12 and opens duct 11 to atmosphere. The ducts 11, 12 may lead to two milk collector tanks or the valve may be used to supply several milking gears in a milking plant which are cycled alternately with pulsating air.
