Title: Improvements relating to roller mills for cereal products
Inventor: LOCKWOOD JOSEPH FLAWITH
IPC: B02C4/28
Filed: 1947-04-21
Abstract: 638,753. Roller mills. SIMON (HOLDINGS), Ltd., H. April 21, 1947, No. 10551. [Class 59] A roller mill for cereal products includes, in combination with a single central feed spout situated at such a height above the feed gate that the stock can spread across or along the full length of the feed gate and of the feed rollers, a control device situated in said spout which, whilst it is operated, to control the feed gate, by the weight or density of the stock which accumulates above it in the spout, does not rise and fall in such stock but has one side only exposed to the stock so that its movement is not restricted by the pile of stock beneath it, the feed spout and control device being of a width less than the length of the rollers and feed gate so that they do not extend the full length of the latter. A hinged control plate o in the lower part of a central feed spout b is so inclined that its movement under the influence of the weight of stock above it is not impeded by stock beneath it. The movement of the plate o controls the opening of a feed gate a, associated with feed rolls c, d, through means including a lever q, a spring-urged member k pivoted at m, and an arm g carried by the spring-urged feed gate a. In a modification, two pivoted control plates may be provided on opposite sides of the feed spout. In another modification the control plate may form part of the lower wall of the feed spout and be hinged at its, the plate's, lower end.

Title: Manufacture of condensation products having a tanning action from dihydroxy-diphenyl and dihydroxy-ditolyl sulphones
IPC: C14C3/20
Filed: 1945-04-27
Abstract: Products having tanning properties in acid medium are made by condensing a mixture of 1 mol. of a dihydroxy-diphenyl- or dihydroxy-ditolyl-sulphone and 1-5 mols. of a dihydroxy-diphenyl or dihydroxy-di-tolyl sulphone sulphonic acid in an acid medium with urea and formaldehyde or with an intermediate condensation product of urea and formaldehyde, for example, a condensation product, for instance, dimethylol urea, obtainable by heating a mixture of 1 mol. of urea to 2 mols. of formaldehyde in a neutral or weakly alkaline medium.  Preferably, 1/2 -1 molecular proportion of urea, or of the intermediate condensation product of urea and formaldehyde is used for each molecular proportion of the sulphone mixture, such proportions yielding a product soluble in acid medium.  The mixture of sulphone and sulphonic acid may be made by partially sulphonating the sulphone or mixture of sulphones.  In examples: (1) 4 : 41-dihydroxy-diphenyl sulphone is sulphonated to the extent of 60 per cent with sulphuric acid, the melt then diluted and urea dissolved in it, and formaldehyde added at 45-50 DEG  C. and the mixture stirred for 20 hours, the product being then neutralized and made weakly acid with formic acid.  A similar product results by partially neutralizing the sulphonation mixture with ammonia and then condensing at 55-60 DEG  C. for 20 hours; (2) a sulphonation mixture prepared as in (1) after cooling and dilution is mixed with a condensation product obtained by boiling urea and formaldehyde in weakly alkaline medium for half an hour, and the mixture is then kept at 45-50 DEG  C. for 17 hours and neutralized and acidified with an organic acid; (3) a sulphonation mixture prepared as in example (1) is mixed with dimethyl-dihydroxy-diphenyl sulphone (prepared from crude cresol) and urea is added followed by formaldehyde. The mixture is heated at 45-50 DEG  C. for 18 hours and then rendered weakly acid with formic acid; (4) the sulphone prepared from crude cresol is partially sulphonated, and a solution of urea in formalin added in two parts, with stirring for 2 hours at 45-50 DEG  C. between the two additions followed by further stirring for 18 hours at this temperature.  The product is then made acid with an organic acid; (5) a sulphonation mixture prepared as in example (1) has added a mixture of urea and biuret, followed by the slow addition of formaldehyde, and the mixture is heated at 45-50 DEG  C. for 18 hours and made weakly acid with formic or acetic acid.  The Specification as open to inspection under Sect. 91 describes the products obtained by condensing a mixture of di-hydroxy di-aryl sulphone and di-hydroxy di-aryl sulphone sulphonic acid in an acid medium with urea and formaldehyde or with a condensation product of urea and formaldehyde. This subject-matter does not appear in the Specification as accepted.

Abstract: 636,726. Refrigerating. HOWARD, A. H., WILKINSON, K., and ROTHERHAM, E. April 19, 1948, No 10736. [Class 29] [Also in Group XXVIII] In a compression, condensation and evaporation refrigerating system the refrigerant is compressed in a cylinder 11 by a differential piston 13, 14 moved during the compression stroke by oil pumped from a reservoir 23 through a pipe 21 by a hand- or motor-operated pump 22 and moved during the return stroke by a compression spring 18 so that power need only be supplied to the system intermittently. Refrigerant compressed in cylinder 11 flows through a coil 16 located in the hollow connecting rod 15 of the piston where it is condensed by the oil which enters the rod 15 through holes 15a. The condensed refrigerant then flows into the cylinder 10 whence it is forced on the return stroke through an expansion valve 20 to an evaporator 19 which is exhausted into the cylinder 11 by the return stroke. Refrigerant non-return valves 17 and 27 are provided. Refrigerant may be charged into the system by either of pipes 24, 25 in vapour or liquid phase respectively. During the return stroke oil leaks back to the reservoir 23. Spring arrangements other than the compression spring 18 may be used for the return stroke. In a modification (Fig. 2, not shown) a condenser external to the cylinders 10, 11 is provided instead of the condenser 16.

Abstract: 978,630. Injection-blow moulding machines. F. FARKAS. March 21, 1963 [Jan. 25, 1963], No. 11226/63. Heading B5A. In an injection-blow moulding machine, a blank is injected into a first mould, transferred to a second mould, and blown into the finished article at the same time as a second blank is being formed in the first mould. In one embodiment a set of blank mould cavities 17, formed by parts 17a and 17b, and two sets of blow mould cavities 28, each being formed by parts similar to 17a and 17b, are carried by stationary member 10, said mould parts being slidable under pressure into member 10 to define the required cavities (see Fig. 8, not shown). Two sets of co-operating neck moulds 56, which comprise sliding members 61, 56a, 56b (see Fig. 5), and which close around plungers 66 to define the neck portion of the article, are carried by a member 54, which is vertically reciprocable in a member 32 which may be moved toward and away from the fixed member 10. Upon abutment of members 10 and 54 a series of closed hollow moulds are formed. In operation, the members 10 and 54 are moved together so that the moulds 56 cooperate with the upper pair of moulds 28 and 17 and blanks are injection-moulded through passage 26 (see Fig. 2), into the moulds 17. At the same time the blanks formed by the previous injection-moulding are blown to the finished articles by pressurized air through the plungers 66 in the upper blow moulds 28. The member 32 is then withdrawn, both the blanks and the finished articles being retained on the plungers, until the member 35, slidable in member 32, abuts the adjustable stop plate 51. Upper plungers 37 fixed to plate 35 are thus forced forward to abut the rear side of the upper plate 61 and to push said plate forward, thus opening the upper neck moulds, continued forward movement of 61 ejecting the finished articles from around the plungers. Block 54 is then lowered relative to member 32 so that neck moulds 56 now co-operate with the lower pair of moulds on member 10. The members 10 and 54 are closed and new blanks are injected into the now empty blank moulds 17 and the blanks previously formed, are blow-moulded in the lower blow moulds 28. The member are withdrawn, the finished articles ejected, the member 54 raised so that the neck moulds again co-operate with the upper form of moulds 28, 17 and the process started again. In a further embodiment (Figs. 14-16, not shown), the neck moulds and plungers are mounted on a rotatable member 154 and co-operate alternately with one set of blow moulds and one set of blank moulds carried by a stationary member 110.
