Abstract: 304,531. Heynert, F. A. H., and British Bead Printers, Ltd. April 19, 1928. Feeding webs.-In a machine for decorating fabrics, the fabric is fed intermittently by means of a chain 69 passing over a sprocket 68 on a shaft 62 carrying a ratchet 67 engaged by pawls 66 carried by a sprocket 61 over which is passed a chain 58 connected at one end to a counterweight 65 and led over a guide wheel 60 and a sprocket 57 and attached to a fixed block 59 at the other end. The sprocket 57 is mounted on the end of the ram 51a of an hydraulic cylinder 51, the ram being guided on a pair of rods 55. A screw-adjustable stop 70 limits the stroke of the ram. Reverse movement of the chain 69 is prevented by driving the sprocket 68 from the shaft 62 through a pawl-and-ratchet gear. A certain amount of lost motion is provided at the end of each stroke of the ram to cause the pawls on the two ratchet gears to overrun the ratchet teeth and settle freely into operative engagement.

The liquid medium is preferably a mineral, vegetable, animal or synthetic oil possessing marked lubricating properties, though other neutral organic liquids of low viscosity, and greases, may be used, and the above-mentioned additions are usually present in the proportion of about 0,1 to 5 per cent. According to examples: (1) One part of a -nitronaphthalene and one part of a -naphthylamine are added to two hundred parts of an oil; (2) m-dinitrobenzene and a -naphthylamine are added to an oil; (3) dibutylamine and m-dinitrobenzene are added to a naphthenic lubricating oil; (4) aniline and a -nitronaphthalene are added to a lubricating oil; (5) aminoazobenzene and a -nitronaphthalene are added to a lubricating oil; (6) 2-nitro a -naphthylamine is added to a lubricating oil; (7) one part of Soya bean oil, which contains lecithins (quarternary ammonium derivatives), and one part of a -nitronaphthalene are added to one hundred parts of oil; (8) a -nitronaphthalene and a -naphthylamine are added to a mixture of alcohols obtained by the reduction of coconut and/or palm kernel oils, or to benzene.  Other amino compounds specified are toluylene diamine, dicyclohexylamine, b -amino anthraquinone, anthranilic acid, lauryl amine, tetrahydrocarbazole, amino phenols, hydrazines, amino diphenyls, nitrosoamines, amino thiazoles, morpholines, pyridines, piperidines, pyrroles, pyrrolidines, acridines, amino acids, ureas, thioureas, guanidines and aldehyde amines.  The nitro compounds used preferably belong to the benzene, diphenyl or naphthalene series, and have not more than two nitro groups in a single nucleus. Specification 337,751, [Class 91], is referred to.  According to the Specification as open to inspection under Sect. 91, the nitro arylamine having an unsubstituted amino group may be replaced by any substance comprising one or more aromatic nitro groups and one or more amino groups.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in washing-up and rinsing machines
IPC: A47L15/46
Filed: 1957-04-12
Abstract: 822,242. Dish washing machines. WEFCOMA INTERNATIONAL A.G. April 12, 1957 [April 13, 1956; Feb. 15, 1957], No. 11993/57. Class 138(1). A washing-up and rinsing machine for crockery, having a compartment in which are located two spraying devices, one for spraying washing-up water on to the crockery and the other for rinsing, and a movable carriage for receiving and supporting crockery, is characterised by the provision therein of a heater through which water for rinsing can flow, the said heater being so structurally combined with a part through which the washing-up water passes that heat is transmitted from said heater to the washing-up water. As shown, sprays 7 and 17 are used for washing and sprays 24 and 25 for rinsing. Water is drawn from sump 2 into pump 4 driven by motor 3 and forced up pipe 6 into sprays 17 and into spraying chamber 7, whence it emerges as jets from perforated plate 8. This plate is provided with a handle 33 to facilitate its removal from the heater when it requires cleaning. Fig. 2 shows an enlarged drawing of heater 18 which is supplied with fresh water from pipe 22, is heated by heater element 20 and has an outlet 23 to sprays 24 and 25 and another outlet 28 which leads to the sump via cock 27 and pipe 29. The heat-conductive wall 30 of heater 18 is provided with fins 31 to increase heat flow into chamber 7. Operation of the machine is started by opening cock 27 and passing water from pipe 22, through the heater and into sump 2. When sufficient water is present cock 27 is closed and remains so until it is desired to replace completely the washing water. The pump is set in operation and plates 9 on a wheeled basket 13 are washed by sprays 7, 17 and then rinsed under sprays 24, 25. The alternative embodiment shown in Fig. 3 has a heater 18 below the sump and water circulated through the washing sprays passes through filter 47 and pipe 5<SP>1</SP> which is heated by water in heater 18. 42 is a drain pipe from the sump. The water heater 18 may be arranged at the side of the trough, or partly or wholly inside, or above instead of below same. In place of electric heater element 20 a gas heater 60 may be used. Water supplied to heater 18 passes through valve 57 which is electromagnetically controlled from the drive mechanism of the basket-like carriage 13 in such a manner that said valve is open only when the carriage is in the rinsing position. The door 12 is flexible and may be coupled to the carriage 13 as described in Specification 667,595 so that on closing the door, the carriage with dirty crockery moves automatically into the position shown in Fig. 1 ; whilst on opening the door the carriage retreats through the rinsing station on to bracket 15.

[Also in Division F4] A food treating apparatus comprises an elongated, horizontally disposed chamber through which a conveyer passes, the chamber comprising a plurality of separable sections 12- 18 in end-to-end relationship, each of the sections comprising a lower body portion A (Fig. 3) and an upper lid portion B both of which extend the entire length of the section. The lid portion is displaceable from the body portion to permit the lifting of the conveyer, and means 49 is situated below the chamber sections to lift the conveyer, the chamber sections being movable endwise between an operating position (Fig. 1) in which they are contiguous to one another, to a cleaning position (Fig. 2, not shown, and Fig. 7) in which they are separated to enable the lifting means to move into engagement with said conveyer. The lid portion B of each section is hinged to the respective lower body portion and has means 24 to partially counterbalance the weight of the lid portion. The lifting means comprises, at least at two points along the length of the conveyer, a screw jack 49 adapted to lift the conveyer. The jacks 49 are connected by transverse drive shafts 52 and a longitudinal shaft 53, with a drive motor 54. Legs 34 carried by a framework 39 of the conveyer may be extended from a normal retracted position (Fig. 4, not shown) to the position shown in Fig. 3, in which they enable the travel of the jacks 49 to be reduced. The conveyer comprises a mesh conveyer belt (not shown) carried by top and bottom conveyer rollers 41 and 42, the whole structure being supported on the bottom walls 38 of the sections by rollers 37 and the framework 39. In order to permit differential expansion between inner and outer walls 72, 73 (Fig. 6) of the lower body portion A, the flangedover upper end of the walls are covered by a slidable cover cap 74. This is held in position by a spring clip 76 which is rigidly attached to the cap 74. Similar connections are provided between the portions A and their end walls (Fig. 5, not shown), and at 84 for the construction of the portion B. A detachable toggle fastening 81 is provided to hold adjacent sections in engagement. The sections 12-18 slide on rails 19 under the action of a manual drive 32. The gaps between sections 12 and 13 ; and 17 and 18, are greater than the remaining gaps in order to provide room for the jacks to extend upwardly into engagement with the conveyer. (For Figures see next page.)

In an example, a porous p.t.f.e. sheet is produced using polymethylmethacrylate as the thermoplastic resin, the resin being removed by extraction with tetrahydrofuran. In further examples, p.v.c. was removed by tetrahydrofuran extraction and polystyrene by heating at 300‹ C. The article produced is for example a filter, a gas diffusion membrane, an electrode or a partition membrane for use in electrolytic cells.
