Title: Process for preparing solidified medicinal and pharmaceutical preparations, disinfectants, and cosmetics
IPC: A61K47/44
Filed: 1933-03-15
Abstract: Medicinal and pharmaceutical preparations, disinfectants, and cosmetics, in the form of solutions or suspensions of solids in liquids, or emulsions of liquids, are solidified by addition of caustic alkalis or ammonia and small amounts (of the order of 0.5 to 2 per cent of the total weight) of resin acids.  The products are stored in collapsable tubes provided with filters.  All preparations which do not react with resin acids or their salts or the alkali can be treated, for example solutions of solids in hydrocarbons or emulsions of hydrocarbons with water or aqueous solutions, oils, or glycerine.  The following substances are suitable: aliphatic hydrocarbons, benzene and its homologues, alicyclic compounds, ethers, esters, organic salts, mixed fats, aromatic ketones, terpenes, camphor, compounds containing condensed aromatic nuclei, and substitution products of these. Reactive substances such as acids, alcohols, amines, aliphatic ketones, aldehydes, heterocyclic compounds, and quinones can only be treated when present to at most about 5 to 10 per cent in the aforementioned substances.  Solutions, emulsions, or suspensions of solids in aliphatic hydrocarbons admixed with about 2 to 10 per cent of aromatic hydrocarbons, chloroform, or ether are particularly stable.  Addition of aqueous ammonia is advantageous, gaseous ammonia or hydrocarbon solutions less favourable. According to examples: (1) A solution of camphor and abietic acid in toluene is mixed with heptane containing oil of Neroli and 10 per cent aqueous ammonia added with stirring; (2) chlorothymol and abietic acid are dissolved in ether and toluene, mixed with octane, and aqueous ammonia added; (3) a mixture of menthol and abietic acid in chloroform, and Eutirsol (ammonium sulphoichthyolicum depuratum) in cyclohexane is solidified in the same manner; (4) sulfoform (tri-phenyl-stibine sulphide) and abietic acid in ethyl alcohol and chloroform, together with ethyl salicylate in octane are treated with aqueous ammonia; (5) thymol and abietic acid in chloroform and benzine are mixed with an emulsion containing lime water, paraffin, olive oil and aqueous ammonia.  The Specification as open to inspection under Sect. 91 refers to the solidification of liquid medicinal, pharmaceutical or like substances.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to cleaning or pickling apparatus
IPC: B08B3/02
Filed: 1946-03-14
Abstract: 609,434. Cleaning or pickling metals. CURRAN BROS., Ltd., and THOMAS, P. H. H. March 14, 1946, No. 7955. [Class 82(ii)] In an apparatus in which articles such as automobile engine cylinder blocks are cleaned or pickled by means of jets or sprays of liquid, the article 1, the outlines of which are shown in broken lines in the Figures, is slid into the chamber 2 by means of the rails 38 and flanged guide rollers 39 up to the stop 45. Cleaning or pickling liquid is sucked from the sump 2b, Figs. 1 and 2, by the pump 5 and delivered via pipe 6 and fixed header 7, the upright tubes 8 to 11, and horizontal tube 12 to the horizontal tubes 13 and 14. Further horizontal tubes 15 and 16 open into the upright tubes 8 and 9. The tubes 8, 9 and 13 to 16 are provided with jet orifices so directed as to spray the exterior surfaces of the block 1, with the exception of the under surface, with the liquid. Additional jets of liquid are directed into holes and recesses in the block such as 18, 19 and 20, Fig. 2, from tubes 17, Fig. 1, 21 to 24, Fig 2, projecting from tubes 10 and 11 and 15 and 16, Fig. 2. Additional liquid is delivered, from header 7, via flexible pipe 25 and header 26 to the spray tubes 30 which have jet orifices along their length as well as at their ends. The header 26 is fixedly mounted on a reciprocable carriage consisting of a rectangular frame 27 at each corner of which is a grooved wheel 28 arranged to ride on fixed vertical guide rails 29. A door 3 mounted on hinges 3a is connected by means of rods 37 and 36 to arms 33a and 33 attached to hubs 32 pivoted about pins fixed to the brackets 31 mounted on the side walls of the chamber 2. The other arms of levers 33 are linked by downwardly depending rods 34 to lugs 35 projecting from the carriage 27 in such a manner that when the door 3 is raised to the open position the carriage 27 supporting the sprayers 30 is lowered sufficiently, as shown in the Figs., to permit the block 1 to be slid into position or removed from chamber 2 without being impeded by the vertical sprayers. The liquid falling from the block 1 drops on to the pitched drain plate 4, Fig. 2, flows into the troughs 41 extending along each side of chamber 2, over the vents 42 and through the filters 43 into the sump 2b. Access to the filters is obtained through hinged covers 44. In the modification of the apparatus shown in Fig. 3 a third portion of the liquid passes from the header 7 via the flexible pipe 25A to a header 26A attached to a second rigid frame carriage 27A similar to the first carriage 27 and located and guided by guide wheels 28A and fixed guide rails 29A. A number of spray tubes 30A project downwards from the header 26A and are so spaced that when the door 3 is closed and the carriage 27A is thereby moved downwards, they enter the cylinder bores of the block 1. At the same time the carriage 27 moves upwards and the sprayers 30 enter the lower or sump space of the cylinder block 1.

Abstract: 526,315. Folding laundered articles; shaft couplings. KAHN, L. M. March 13, 1939, No. 8029. Convention date, March 16, 1938. [Class 42 (ii)] [Also in Group XXIV] . In a machine for folding flat articles such as laundry work, in which the work is fed by 100 sets of'tapes &c. 12, 14 to folding elements 18, 38 which introduce the articles between the folding rollers &c. 28, 40<SP>1</SP>, these elements 18, 38 are divided into sets corresponding to several feed lanes through the machine, and the size of the sets can be varied automatically or otherwise. As shown, a flat article introduced at 10 may pass unfolded down the pan 20 and be delivered by the belt 22 on to the table 24, may be doubled once and pass down the pan 30 and on to the table 24, or may be doubled twice and pass down the pan 42 and on to the table. The folding elements 18, 38 are operated pneumatically, electrically, or otherwise under the control of apparatus 58, 60 which measures each flat article 50 and causes it to be folded say first at a third of its length and then at the middle of the remainder. To prevent the unfolding of the first third of the article at the time the second fold is made each folding element 38 is provided with a second workengaging element 52, Fig. 12, resiliently mounted by means of a spring 54 so that it presses on the work after the element 38 has been drawn out of the grooves in the folding rollers &c. (see Fig 14). One folding element of each se e.g., the element 170, Fig. 10, is operated by cam 108, Fig. 6, or otherwise, all the other folding elements 18, 38 in the set being temporarily coupled to this element. This coupling may be effected by levers 102, 122, 144, 178 pivoted to one folding element and engaging in a slot &c. in the adjacent folding element, or by bars 164, Fig. 5, sliding in slots or grooves 162 in the folding elements 160. The levers and bars are operated by pull rods &c. 104, 180, 166, sliding cams &c. 112, 124, or automatically by wires 142, Fig. 9, connected to rollers 140 loose on the same shaft as, and between the feed tapes 12, 14. By this means folding elements are coupled corresponding to the width of each article to be folded. When wider articles are being folded the timing mechanisms 60 of two or more lanes are coupled together. U.S.A. Specification 2,034,040 is referred to. Reference has been directed by the Comptroller to Specification 131,915 [Class 42 (ii)].

Abstract: 1,177,192. Magnetic tape data stores. R.C.A. CORPORATION. 20 Feb., 1968 [9 March, 1967], No. 8196/68. Heading G4C. [Also in Division H3] A circuit for connection to the monitoring head of a tape recorder to check whether the phase modulated digital data signals have been correctly recorded comprises a pulse discriminator having gating circuits coupled to a balanced signal source and controlled by respective signals produced if the input signals exceed a positive or a negative level for more than a given time. In Fig. 1, the amplified and equilized pulses are applied to a circuit 15 which produces outputs only if the positive or negative signals exceed a threshold level. The output pulses of this are applied to integrators in block 18 and if the pulses exceed a given duration a threshold level is reached which through threshold circuits 21 set a bistable circuit 24 or 25 depending on whether the signal is positive or negative. The input pulse is also applied to a crossover detector 6 the output of which is applied to gating circuits 11 and 12 for positive and negative slope signals respectively, the other inputs of the gates being derived from the bi-stable circuits. An output indicating a correctly recorded signal is thus provided by the gates and this is used to reset a corresponding bi-stable circuit through a line which may include a delay chosen to prevent "race" problems. Fig. 2 shows the threshold detectors and integrators. If the positive going position of a pulse exceeds the threshold of conductivity of transistor 36, transistor 37 is cut off and an integrator capacitor 39 charges. If the pulse subsists sufficiently along the resulting voltage will reach a valve sufficient to switch on transistor 41. This switches off 42 and causes Zener diode 44 and thus transistor 45 to conduct. The lower half of the circuit operates similarly for negative signals diodes 35 and 51 by-passing the irrelevent polarities.

Abstract: 1459297 Milk replacer compositions BRITISH PETROLEUM CO Ltd 22 Feb 1974 [2 March 1973] 8224/74 Heading A2B  Milk replacer compositions for young animals, are made by adding powdered microbial proteinaceous material to a molten fat, so that the fat is absorbed into the proteinaceous material and mixed with one or more milk replacer components e.g. lactpserum, dextrins, starches, glucosides. The weight ratio of proteinaceous material to fat is between 1:4 and 4:1. The fat may have a m.p.t. below 100C and the protein is added to it at a temp. between the m.p.t. and 100C. The fat may be lard, tallow or copra. The powdered proteinaceous material may be derived from yeast in the form of a hydrolysate, concentrate or isolate. The yeast may be grown in aerated submerged fermentation in an aqueous nutrient using a hydrocarbon as carbon source, and may be Candida tropicalis or Candida lipolytica. The proteinaceous material may be lipophilic and may be pretreated with an organic solvent. Mineral and vitamin supplements and/or skim milk powder may also be included. This may be done either by forming an aqueous emulsion of the refatted protein in a solution of the other ingredients, using a sucroglyceride, monostearate, lecithin or a polysaccharide as emulsifying agent, and then drying, or by injecting atomised droplets of the molten protein product into a dispersion in air of the other ingredients, the average size of the droplets and particles being below 100 microns.
