Abstract: 698,867. Feeding webs. NATIONAL TEA PACKING CO., Inc. May 24, 1949, No. 13785/49. Class 100(i) [Also in Group XVII] In a machine for forming tags of folded sheet material and attaching them to tea-bags (see Group XVII) a web of material W from which the tags are formed is fed from a supply roll M over a roller 52, a looping roller 53 carried by a spring- loaded bell-crank 54 operated through linkage by a earn 54j, and a third roller 52a from which it passes downwardly through a cam-operated clamp to a feeding device 60, Fig. 10, comprising an oscillating finger 65h arranged to engage spaced holes J in the web. The finger is given a combined vertical and transverse oscillatory movement, whereby it engages a hole J on the downstroke, but is moved clear of the web on the upstroke. The looping roller and clamp are operated in synchronism with the feeder 60 and the clamp may be released by a manually operable lever to enable the web to be fed manually at the commencement of operations. The mechanism is duplicated so that two webs are fed simultaneously. Specification 572,315, [Group XVII], and U.S.A. Specification 2,428,026 are referred to.

Patent GB-456741-A (GB)
Title: Manufacture of tanning agents
IPC: C14C3/20
Filed: 1935-05-13
Abstract: Tanning-agents are obtained by condensing a sulphonated phenol with urea (or a compound which forms urea) and formaldehyde (or a compound which yields formaldehyde, or a urea-formaldehyde condensation product of low molecular weight prepared in an acid medium) under conditions which are appreciably milder than those prescribed in Specification 305,013, [Class 2 (iii)], i.e. in a medium of lower acidity and/or at a lower temperature, the reaction being interrupted as soon as or shortly after the product has become soluble in water. A diagram is given showing the correlation of acidity, temperature and time of reaction for the cases in which sulphonated phenol and sulphonated crude cresol are condensed with specified proportions of urea and formaldehyde; extreme conditions of reaction, in the case of sulphonated phenol, are (a) the acidity is that obtained when 100 parts of phenol are sulphonated with 100 parts of sulphonating agent and the product is diluted with water to 250 parts, the temperature is about 50 DEG  C., and the reaction is effected in 15 minutes; a lower or higher temperature may be applied for a longer or shorter time respectively; (b) the acidity is that obtained when the diluted sulphonation mixture specified at (a) is neutralized to the extent of at least 77 per cent, and the reaction is effected at about the normal boiling temperature for 15 minutes, or at a lower or higher temperature for a longer or shorter time respectively. When sulphonated crude cresol is taken, the reaction is generally effected, other conditions being equal, at 15--25 DEG  C. lower than when sulphonated phenol is taken.  Examples are given illustrating the manufacture of products from (1) sulphonated crude cresol, urea and formaldehyde; (2) sulphonated crude cresol and a urea-formaldehyde condensation product prepared in the presence of sulphuric acid; (3) sulphonated phenol, urea and formaldehyde. The products are brought to an acidity suitable for tanning by addition of phosphoric and/or oxalic acid, and may be used alone or with other tanning or non-tanning substances.  Specification 388,475 also is referred to.

Filed: 1925-05-28
Abstract: 251,121. Rushen, P. C., (Maschinenfabrik Augsburg-Nurnberg, Akt.-Ges.). May 28, 1925. Cylinders receiving liquid fuel.-In an engine of the solid fuel injection type, the air suction valve or the cylinder cover is provided with a device serving to definitely direct a current of cool air or gas on to the fuel injector to prevent the accumulation of carbon deposits thereon. In the form shown in Fig. 1, the head of an inlet valve g of the poppet type situated adjacent the injector a carries a flat shield h normal to the valve axis, disposed so that the entering air is directed over the injector. In the construction shown in Fig. 2, the injector a is surrounded by a sheet-metal casing j forming therewith an annular slot k adjacent the delivery orifices of the injector. The casing j is in communication with a valve n, through which in the case of a four-stroke cycle engine atmospheric air is sucked, and in the case of a two-stroke cycle engine scavenging air or other gas under pressure is supplied. Alternatively, the valve n may admit blasts of air under high pressure drawn from the same source as the starting air, at longer intervals than once every cycle. In a modified construction, the valve n is omitted, and the casing j extended radially in such a manner that air whirling within the cylinder will enter the casing j through an opening provided near the periphery of the cylinder, and be discharged through the annular slot k.

In an air distributing system of the kind in which a variable amount of air is supplied to keep the temperature of a room at a desired value, the air is supplied in two separate streams of which the first has a constant small volume and a constant high speed and the second has a relatively large volume which is varied to maintain said desired temperature and a relatively low speed, the momentum of the first stream being so high compared with that of the second that variations in the second stream air flow make only a negligible difference to the total momentum of the two air streams. The high speed stream is supplied through a pipe 1 and nozzle 5, the low speed stream through a pipe 2 and outlet 9, this stream being throttled by a fixed member 11 and controlled via a flap valve 12 by a thermostat 14.

Abstract: Monomers of formula <FORM:0579379/IV/1> , where R1 is a hydrogen atom or an alkyl group containing not more than four carbon atoms and R2 is a carboxylic acid ester group or a nitrile group are polymerized in aqueous medium, using sulphur dioxide as catalyst.  Preferably, the monomer is insoluble in water and preferred monomers are the nitriles or esters of acrylic or methacrylic acid, e.g. methyl acrylate, methyl-methacrylate, ethyl acrylate, acrylonitrile and methacrylonitrile.  The aqueous medium may comprise a water-soluble solvent for the monomer, such solvents being methanol, ethanol, isopropanol, glycol, glycerol and acetic acid. The catalyst may be formed by dissolving sulphur dioxide in the aqueous media.  Instead of free sulphur dioxide, there may be used salts or other substances yielding sulphur dioxide in aqueous solution, e.g. alkali-metal sulphites, bisulphites and meta-bisulphites such as sodium sulphite and potassium metabisulphite.  Plasticisers, colouring agents, dispersing agents, protective colloids, surface tension controllers and pH controllers may be incorporated.  In examples, potassium metabisulphite is used to polymerize (1) methyl methacrylate in methanol-water, (2) methyl methacrylate in ethanol-water, (3) methyl methacrylate in isopropenol-water, (4) methyl methacrylate dispersed in water by means of sodium sec-octadecyl sulphate, and aqueous sulphur dioxide is used to polymerize methyl methacrylate.
