Patent GB-1018404-A (GB)
Title: Block copolymer lattices and process for their preparation
IPC: C08F6/20
Filed: 1963-09-25
Abstract: Stable concentrated latices of block copolymers are made by taking a dilute latex of a block copolymer of the formula A-B-A, B-A-B or A-B in which each A is an independently selected non-elastomeric polymer block having an average molecular weight in the range of 2,000 to 100,000 and a glass transition temperature above 25 DEG  C. and B is an elastomeric polymer block having an average molecular weight in the range of 25,000 to 1,000,000 and a glass transition temperature below 10 DEG  C., the dilute having a polymer: water ratio between 1:10 and 1:50, and adding thereto a normally liquid aliphatic hydrocarbon and/or a solution of a diene rubber dissolved in an aliphatic hydrocarbon in an amount such that the weight ratio of liquid aliphatic hydrocarbon added, either as such or as contained in the rubber solution, is between 1:1 and 5:1, and leaving the dilute latex in intimate contact with the added aliphatic hydrocarbon for a period of at least 1/4 hour, removing the added aliphatic hydrocarbon and concentrating the latex to a polymer content of at least 25% by weight.  The resulting latices may be used in the production of dipped goods and coated or foamed rubber articles. The examples describe emulsifying in water benzene solutions of styrene-isoprene and isoprene-styrene-isoprene block copolymers, removing the benzene to produce dilute polymer latices which are then contacted with heptane or isopentane, followed by the removal of the aliphatic hydrocarbons and concentration of the resulting latices.

Abstract: 388,883. Coating with metals ; cleaning metals. THOMAS, H. S., Melingriffith Works, and DAVIES, W. R., St. Petroc, Park Road, both in Whitchurch, Glamorgan. Dec. 8, 1931, No. 33967. [Class 82 (ii).] In apparatus employed in the manufacture of tin or other metal coated plates or sheets in which one unit of the plant delivers two or more plates or sheets simultaneously and abreast, two or more conveyers are arranged so that the plates or sheets delivered abreast are fed singly and in succession to the succeeding unit, one of the conveyers transferring the plates or sheets delivered to it direct to the succeeding unit. In the form shown two plates X, X<1> are delivered simultaneously and abreast from the rolls C<1> of the grease pot C. The plate X passes down guides 11 on to an endless conveyer comprising a plurality of belts 3 passing round pulleys 4 and rollers 5 on shafts 6, 7 respectively and is transferred directly to feed rolls A<1> of a branning machine A. The plate X<1> is received by an endless conveyer mounted above and inclined with respect to the conveyer 3, the conveyer comprising a plurality of belts 13 passing round pulleys 12 on the shaft 6 and round inclined guide pulleys 14, 15. The delivery end of the conveyer 13 is positioned above the conveyer 3 and the conveyers are driven so that the plate X<1> falls on to the conveyer 3 after the plate X has passed to the rolls A<1>. The belts 3, 13 of the conveyers are kept taut by pulleys 9, 16 respectively, the former being carried by a weighted lever 10. More than one inclined conveyer may be provided if more than two plates are delivered simultaneously from the grease pot C, and in the form described the arrangement is duplicated, two cleaning machines being provided. Specification 109,302, [Class 82 (ii), Washing granular &c.], is referred to.

Abstract: 1458290 Dough dividing and extruding AMF CORP 1 Aug 1974 [5 Oct 1973] 33970/74 Heading B5A A hopper 2 (Fig. 1) receives dough intermittently or continuously and feeds a stream for kneading to the nip of adjustable speed counter-rotating rollers 4 in a chamber 1. Doctor blades 9 feed the dough through a rectangular chamber 10 (Fig. 2a, section) to a confining chamber 12, where the stream is divided by a baffle 13 and passes through two fixed orifices 15a. A plate 5 is moved by a camcontrolled linkage 17/20 (Fig. 1) to align two orifices 15b with the fixed orifices for the passage of dough. After a controlled dwell period, the plate 5 is moved to disalign the orifices so that knife edges on the orifices 15b cut-off a pair of dough pieces, which are received in baking pans or on a band conveyer 10 (Fig. 1). The shape of the dough pieces is varied by altering the shape of orifices 15b and their stroke and dwell period, to give hamburger, frankfurter or circular buns. The baffle 13 is adjustable by a screw 16 for equal flow rates of the divided stream.

Class 107 Loose objects and dirt are cleared from airfields by a vacuum cleaning vehicle in which air is circulated at a high velocity from a blower to the underside of the front of the machine, and is drawn into a suction pipe at a point nearer to the rear of the machine entraining dirt and debris, this entrainment being assisted by a projection from the underside of the machine which almost touches the ground and which serves to deflect heavier objects into the air stream. As shown, the vacuum cleaner assembly C, pivoted to the chassis 20 of the vehicle at 46 and supported partly by the hydraulic cylinders 55 and partly by castors 52, has a blower 40 connected to ducts 35 and 36, which extend across the width of the machine, and a pair of suction ducts 34 which lead to a pair of separators 30 and associated hoppers 38. The intake of air to the system is regulated by an adjustable flap 74 fitted to the underside of duct 36, and flexible curtains 82, 66, 65, and 95 enclose the treatment zone. Spring-loaded blades 102 and 100 deflect material into the appropriate branches of suction duct 34 and the airstream carrying such material passes into the pair of separators 30, which have freely mounted circular filters rotated by the airstream, and the debris falls into hopper 38 whilst the cleaned air is recirculated. The vacuum cleaner assembly may be -raised clear of the ground by hydraulic cylinders 55 for driving the vehicle along the road.

Cephalosporins effective against Salmonella are 7-(4<SP>1</SP>-purazanalkanoyl)-aminocephalosporanic acids, salts or derivatives of Formula I wherein R<SP>1</SP> and R<SP>2</SP> are each H or C 1-10  alkyl; A is H, OH, C 2-8  alkanoyloxy, benzoyloxy, quaternary ammonium (e.g. pyridinium, quinolinium, picolinium or lutidinium) or, when taken together with M, a monovalent C-O bond; and M is H, a pharmaceutically acceptable non-toxic cation, an anionic charge when A is a quaternary NH 4  radical or, when taken together with A, is a monovalent C-O bond. Typical compounds are 7-[α-(3-methoxy- 4 - purazan) - acetamido] - cephalosporanic acid, 3 - pyridiniummethyl-7-[α-(3-methoxy-4- furazan) - acetamido] - decephalosporanic acid inner salt and 3-hydroxymethyl-7-[α-(3-methoxy - 4 - furazan) - acetamido] - decephalosporanic acid. Salts are formed with metals such as Na, K, Ca and Al and with organic bases, e.g. triethylamine, procaine and dibenzylamine. Compounds of Formula I are prepared by acylating a compound of formula wherein A is as defined above, or a neutral salt thereof with an acid of formula or an acylating derivative thereof, wherein R<SP>1</SP> and R<SP>2</SP> have the above meanings. Where A is alkanoyloxy, the resulting compound may be treated with a tertiary amine to form the corresponding quaternary ammonium inner salt. 3-Hydroxy-4-furazanacetic acid is produced by treating hydroxylamine HCl with diethyl oxalacetate sodium at pH 8-8À5, followed by acidification and formation of the N,N<SP>1</SP>-dibenzylethylene diamine salt, from which the free acid is recovered. 3-Methoxy-4-furazanacetic acid is prepared by treating 3-hydroxy-4-furazanacetic acid with diazomethane in ether. A pharmaceutical composition for human or animal use comprises a cephalosporin of Formula I and a carrier. The cephalosporins may be used for treating mastitis in animals, as antibacterial agents and as nutritional supplements in animal feeds.
