Title: Improvements in graduated scales used for or in connection with measuring or indicating
IPC: G01B3/18
Filed: 1919-02-05
Abstract: 139,273. Saunders, C. E. Feb. 5, 1919. Dials and scales.-Relates to the method of inscription of the graduations in the scales of instruments or machines so as to facilitate reading them. The method, shown applied to the decimal division, but applicable generally, consists in a particular system of making the marks of different length according to position. The marks for fivepositions being as usual shorter than the marks for ten-positions, the marks for adjacent readings, i.e. for one, four, six, and nine, are longer than the intermediate marks, as shown in Figs. 1, 6, and 7, or shorter as shown in Fig. 2. Lines parallel to the edge of the scale may run through the longer or shorter marks exclusive of fives and tens. As shown in Fig. 5, the method applied to slide rules indicates readings of similar denomination clearly. In rules carrying scales of different kinds of sub-division, the decimal divided scales can be thus rendered more distinct.

Title: Improvements in or relating to apparatus for bending or creasing cardboard, fibreboard or the like
IPC: B26D3/08
Filed: 1932-01-30
Abstract: 390,912. Grooving cardboard. VICKERS-ARMSTRONGS, Ltd., Vickers House, Broadway, Westminster, and NASMITH, J. I., 12, Glenshiel Road, Eltham, London. Jan. 30, 1932, No. 2877. [Class 100 (ii).] Apparatus for bending, creasing, or scoring cardboard or the like, in which the bends or creases are formed by the action of rotarv tools, is provided with means which buckle the board and impart thereto a contour of undulating or multi-curvilinear form, before the boards are fed to the bending or creasing tools, without compressing them, thus providing between each pair of adjacent creasing or bending tools surplus material from which the additional matter required for the creases or bends can be obtained. The board 3, before passing to the bending or creasing tools 4, is reduced in its effective width by curving the board by means of upper rolls 5 and lower rolls 6, arranged as shown, whereby surplus material is obtained from which the additional material required for the creases &c. can be obtained. The number of undulations formed and their extent depend upon the number of creases &c. to be formed, the class and weight of the material, and the particular form of creasing or bending apparatus used. The rolls may be varied and for this purpose the rolls 5 are mounted in supports 5a carried by bearing blocks 7 horizontally adjustable upon a transverse bar 8, and for vertical adjustment the supports 5a are provided with slots 5b which embrace the blocks 7 ; the supports can be adjusted by screws 9 threaded into the blocks 7 and are normally urged upwardly by springs 10. The lower rolls 6 may be carried on a shaft 6a by supports 6b similarly mounted for horizontal adjustment on a bar 11. In a modification, when the creases &c. are widely spaced, each lower roll 6 is situated below and between two upper rolls 5, which co-operate to produce curved portions separated by substantially rectilinear portions.

Title: Improvements appertaining to ambulances
IPC: A61G3/00
Filed: 1930-01-29
Abstract: 346,494. Ambulance vehicles. SOUTHERN, H., 284, Blackburn Road, Bolton. Jan. 29, 1930, No. 2994. [Class 108 (i).] In ambulances provided with stretcher supports operated by hydraulic apparatus and in which each support has provision for an upper and a lower stretcher the actuation of the supports is controlled by means of a valve which on lowering the supports is automatically and gradually closed to cushion the descent. The pressure fluid is pumped into the barrel 2 mounted to oscillate about trunnions 2a by a lever 5 and the ram 4 is connected to a lever 3 carried by a shaft 10 upon which the arms 9 of the stretcher support 8 is carried. When the support is raised by the pressure fluid the latter may be cut off by means of a valve 7 and lever 6 which latter is moved over as shown in dotted lines in Fig. 3. To lower the support the lever 6 is moved back to the full time position to open the valve and allow the pressure liquid to escape. As the support approaches its lowermost position the valve 7 is gradually closed by means of a cam surface 17a on a cam member 17 contacting with a pin 6a on the lever 6. In a modification the barrel 2 is mounted in an upright position. A catch 12 operated by a hand lever 14 and rod 13 is employed to lock the apparatus in its elevated position.

Patent GB-784871-A (GB)
Title: Improvements in or relating to the production of artificial sausage casings
Inventor: FOX BERNARD VICTOR
IPC: A22C13/00
Filed: 1955-02-03
Abstract: In the production of sausage casings an aqueous solution of an alginate is extruded through an annular nozzle into a coagulating bath containing a water-soluble calcium salt and also a water-soluble alkali metal or ammonium salt, present in a proportion of at least 0.5 per cent by weight, which does not react with the calcium salt to form a water-insoluble salt by double decomposition.  The concentration of calcium salt may be between 0.1 and 30 per cent by weight.  Specified calcium salts are the chloride, chlorate, nitrate, or acetate or mixtures of these, while the sodium, potassium or ammonium salts preferred are the chloride, nitrate or bromide.  The bath may also contain an acidic substance, e.g. hydrochloric or acetic acid, such that the pH of the bath is 6 or less.  The tubular casing may be subsequently passed into a bath containing a water-soluble calcium salt in a proportion of 10-25 per cent by weight to complete conversion of the water-soluble-alginate to the corresponding calcium compound.  This second bath may also contain a sodium salt whose concentration is below 3 per cent by weight.  The drying of the casing is normally effected by passing it over drying rollers at 70-90 DEG C.  The alginate casing may be rehumidified or wetted with water or softened with aqueous glycerine before collecting on reels.  Specification 784,235 is referred to.

Title: Improvements in flat bed knitting machines
IPC: D04B7/02
Filed: 1949-02-08
Abstract: 671,932. Knitting-machines. MORLEY, Ltd., I & R., HARRISON, A., and HOWITT, A. E. April 28, 1950 [Feb. 8, 1949], No. 3380/49. Class 74 (ii). To enable intarsia or Argyle patterning to be produced on a single flat bed machine having independently operable needles, two yarn carrier bars 5, 6 are provided each having a number of carriers 32, 33 which feed yarns to groups of needles for the knitting of each course. Before the needles are manipulated by the cam box to knit the course, the carriers are returned to a position at the back of the needles and after completion of the knitting of the course the carriers are brought to the front to feed yarn for the next course. Whilst at the back of the needles the carrier bars are shogged by altering the position of their end stops so as to vary the number of needles to which the carriers feed yarn in each course thereby enabling the patterned fabric to be produced. In addition, embroidery thread carriers 76, 77, which are shogged a single needle spacing each course, may be provided for producing diagonal lines across the fabric. Thread carrier bars 5, 6 are mounted on members 7 and 12, 13 slidable on rails 8 and 15. Projections 16 extend from the members 7, 13 and engage the arms of drivers 17, 18 secured to a driving bar, the drivers releasing the projections 16 at the end of each carrier bar traverse. The rails 8, 15 are mounted at their ends in slides 9 which are guided in brackets 10 on the end frames of the machine, the slides 9 being actuated by levers 34 operated by levers 37 controlled by the cam box to project the yarn carriers across the needle row at the end of each cam box traverse. To produce intarsia work the traverse of one of the carrier bars and its guides is reduced whilst the other has its traverse increased and this is achieved by end stops 22, mounted on bars 20, 21 adapted to engage stop pins 23 in the members 7, 12, 13. The bars 20, 21 are shogged by means of stepped cams operating on their end portions. Embroidery thread guides 76, 77 are similarly mounted and operated except that their movements are controlled by ratchet and pinion mechanism which ensures that single needle space traverse only is obtained for each course of knitting, mechanism also being provided for reversing their movements when they reach the end of the needle row.

Title: Molding Machine.
IPC: B22C15/10
Filed: 1918-02-26
Abstract: 123,581. Marks, E. C. R., (Nicholls Co., W. H.). Feb. 26, 1918. Mouldings-machines.-A moulding-machine has the pattern-supporting means 40 and the stripping means 43 independently movable, but both carried by jarring means, such as a plunger 34 in a cylinder 33, which is mounted in a larger cylinder 11, for squeezing the mould against an adjustably mounted platen 28. Means such as a rack-and-pawl device 53, 54, Fig. 6, prevent the lowering of the stripping means 43 and mould flask 44, when removing the patterns 41. A single valve 68 controls the fluid-pressure supply to both cylinders 33 and 11. The stripper plate 43 carries bodies 60 which form hollows in the mould, which thus requires less sand, and the hollows also facilitate the escape of gases during casting. U-shaped connexions 46 are provided between the interior and exterior portions of the stripper plate, between which portions the patterns 41 can slide to be withdrawn from the moulds. In operation, after sand has been filled into the flask 44, the valve 68 is operated to admit air through the pipe 65<a> to the cylinder 33, thus lifting the plunger 34 and parts supported thereby, until the lower end of the plunger passes the vent holes 66. The plunger then drops against the cylinder and the operation is repeated as long as required. The valve 68 is then operated to admit air to the large cylinder 11, which raises the mould against the platen 28 to compress the sand. A further operation of the valve 68 allows the air to escape at an adjustable rate from the cylinder 11. After a slight lowering of the mould and stripper plate, the pawls 54 engage the racks 53 and hold the mould 44 and plate 43 in the raised position while the patterns 41 are withdrawn, pillars 51 sliding in sockets 50 permitting of this relative movement. When the patterns are completely withdrawn, the mould 44 is removed and a pedal 59 is operated to release the pawls 54 and return the parts to their initial positions.

Abstract: 1,241,642. Peristaltic pumps. EFCO Ltd. Jan.23, 1970, No.3495/70. Heading F1F. [Also in Division C7] An electro-plating tank 10 is supplied with additive(s) (such as acid and a brightener from containers 39, 40) by means of a peristaltic pump 24 whose speed is controlled so as to be proportional to the electro-plating current. A current sensing device (such as a series resistance 22 or an electromagnetic transducer in the cathode, or anode, supply) provides an input to a voltage amplifier 34 and the output from the amplifier controls the pump speed. The pump output can be altered by adjusting the value of a resistance in the amplifier 34. As shown, two additives are pumped through two plastics tubes 27, 28 by a single pump but two pumps may be used. Conventional means may be provided for heating or cooling the bath in the tank and for providing agitation of a work bar 18.

Title: Vinyloxyaryl mono sulphonic acids and salts thereof and their polymers
IPC: C08F16/12
Filed: 1960-02-01
Abstract: The invention comprises a homopolymer of a vinyloxyaryl monosulphonic acid of the formula CH2=CH-O-Ar-SO3H or salt thereof, wherein Ar represents an aromatic hydrocarbon group or an aromatic hydrocarbon group containing an alkyl, cycloalkyl, aryl or halogen substituent (see Group IV(b)) and a copolymer of such a vinyloxyaryl monosulphonic acid or salt thereof with an unsaturated monomer.  The aromatic group may be derived from benzene, diphenyl, naphthalene or anthracene and their alkylated homologues.  Unsaturated monomers mentioned for use in copolymer preparation include olefines, diolefines, vinyl aromatic compounds, vinyl ethers, esters and ketones, unsaturated acids, esters, amides and nitriles.  Copolymers mentioned include those obtained by copolymerizing vinyloxyaryl monosulphonic acids with acrylonitrile, optionally with an acrylic or methacrylic ester in addition.  The polymerization is preferably carried out with the monomer or mixture of monomers dispersed in an aqueous medium in the presence of a conventional polymerization catalyst. Copolymers containing high proportions of sulphonic groups are water soluble and those containing lower proportions have affinity for basic dyes.  The copolymers containing high proportions of sulphonic groups may be mixed with homopolymers and copolymers of acrylonitrile.  In examples: A mixture of acrylonitrile, potassium vinyloxybenzene monosulphonate, water, sulphuric acid, sodium bisulphite and potassium chlorate is heated to obtain polymers from which films are prepared (II); in a similar process methyl methacrylate is included in the reaction mixture (III) and in a similar process the polymerization is carried out continuously, the product being converted to fibre and dyed.ALSO:The invention comprises vinyl-oxaryl monosulphonic acids of the general formula CH2=CH-O-Ar-SO3-H and their salts, where Ar represents an aromatic hydrocarbon group or an aromatic hydrocarbon group containing an alkyl, cycloalkyl or aryl substituent or halogen substituent and a process for the preparation of the alkali metal salts which comprises sulphonating a compound of the general formula Hal-CH2-CH2-O-ArH where Hal is a halogen atom and subjecting the product to treatment with alkali metal hydroxide. The products are employed in the production of resinous homo- and copolymers (see Group IV(a)).  The sulphonation is effected with any known sulphonating agent, e.g. hot concentrated sulphuric acid.  The aromatic group may be derived from benzene which may be alkylated or cycloalkylated, diphenyl, naphthalene or anthracene and their alkylated, homologues.  The preparation is described of sodium vinyloxybenzene mono-sulphonate by sulphonating b -bromo-ethoxy-benzene with sulphuric acid and dehydrohalogenating the product with sodium hydroxide solution. Halogenethoxy aryl compounds for use as starting materials are obtained by reacting dihalogenethanes, especially dibromoethane, with appropriate phenols in the presence of alkali.
