Abstract: 1,114,024. Seaming non-metallic sheet material. CONTINENTAL GUMMI-WERKE A.G. 30 June, 1966 [27 Aug., 1965], No. 29389/66. Heading B5K. In a method of joining similar pieces of webs of material embedded in rubber to form a continuous web by pressing the end edges of a piece of web 8 and a web 9, after alignment against a stop 14 located between the edges, into abutment with each other by rails 11 movable at an incline to and against each other on to the ends to connect the web edges together by the adhesiveness of the material, the ends to be joined are bent upwardly or downwardly when their edges are pushed against the stop 14 and are subsequently pushed back into the plane position by compression without displacement of the web 9 or the piece 8. Joining apparatus comprises two conveyer tables (1), (2), Figs. 1 and 2 (both not shown), between which a conveyer table 3 is rotatably mounted. A conveyer surface 4 is formed by ball rollers (5) and conveyer rollers (6). The table 3 is pivotable relative to the direction of feed so that cross-cut pieces may be joined and a beam 7 is rotatable therewith. The beam 7 is adjustable in height to alter the distance between the lower surface 10 thereof and the conveyer surface 4. The rails 11 are mounted in the beam 7 and are adapted to be pressed downwardly by inflatable tubes 12 against the force of helical springs 13. A tubular crosspiece 15, inflatable through a line 16, is countersunk into the surface of the table 3 below the stop 14 to be normally level with the surface 4. In operation, the cross-piece 15 is inflated to lie above the surface 4 and the web 9 and the piece 8 are pushed against the stop 14 with their ends curving upwardly. The tubes 12 are inflated to move the rails 11 downwardly. The end edges slide off the stop 14, abut each other and are pressed together. The cross-piece 15 is deflated, Fig. 5 (not shown), and fingers 17 on the rails interengage to smooth the seam. The rails 11 are raised, Fig. 6 (not shown), and the seam line is moved on.

Abstract: 171,114. Barnerias, J. C., Pataud, A., and Boucheron, L. F. J. Nov. 6, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Cutting-edges, shaping and treating.-Knives and other cutlery are ground and sharpened by a grinding-wheel carried by a pivoted arm, which is caused to rise. and fall, during the passage of the knife to and fro beneath the grinding-wheel, by a templet having a profile corresponding to that required for the knife. The grinding-wheel 17 is journaled in a frame carried by arms 9, 9<a>, 11, 11<a>, which at one end are pivoted on a shaft 5 rotating in a bearing 4, and at the other end carry a bracket 12 forming a bearing for a nut 24<a>. The nut is operated, through worm gearing 24, 25, by a handle 27 and engages a screw 28, which carries at its lower end a ball 29; operation of the nut causes the grinding-wheel to fall, or to rise, to compensate for wear. The screw is positioned at its lower end by braces 31, 32 extending between a collar 33 and the shaft 5. The knife 47 is mounted and clamped on a support 45 carried by a compound slide 35, 39. The slide 39 is reciprocated, in a direction transversely of the knife by a connecting-rod 40 operated by a crank 41a which is driven, through gearing 41, 43, by the shaft 5. The connecting-rod is guided, against transverse movement, by a fixed guide 58 and is connected to the slide 39 through a rod 40<b> extending beneath the slide. The slide 35 carrying the slide 39 is movable lengthways of the knife by a screw operated by a hand-wheel 37, or automatically. The slide 39 carries a templet 46 having a profile corresponding to the shape of the knife-blade, and the ball 29 is held in contact with the templet by a spring 48. The blade is pressed down during grinding by a spring-pressed roller 50. Water is supplied by a pump driven from the shaft 5, a water receptacle 2 being provided. In operation, the knife and the templet are reciprocated beneath the grinding-wheel and the ball respectively and are traversed by operation of the hand-wheel 37; the grinding-wheel rises and falls, and thus produces a section on the blade which is a copy of the contour of the templet.

Title: Improvements in and relating to plates for secondary batteries
IPC: H01M4/76
Filed: 1934-10-16
Abstract: 445,708. Batteries. STONE & CO., Ltd., J., Deptford, and CHILTON, A. H., 200, Brompton Road, Chelsea, both in London, and SCHOFIELD, W., 7, Dynevor Gardens, Leigh-on-Sea.. Oct. 16, 1934, No. 29597. [Class 53] [See also Group V] An accumulator plate consists of a number of perforated or porous tubes 3 which are provided with inner tubular sheaths or linings 7 within which the active material 1 is contained. The linings 7 are made of fibrous material such as glass wool or nitrocellulose, and the active material surrounds rods 2 connected to bars 5, 6. The tubes 3 may be made of ebonite and may be provided with ribs 4, and the area of the perforations in the tubes may be from 28 to 35 per cent of the surface of the tubes. In one method of making the plate the tubes 3 are first assembled on the bottom bar 6 and around the rods 2. The linings 7 which may be cemented to tubular form are then placed in position in the tubes and powdered active material is dropped into the spaces between the linings and rods 2. The structure is vibrated to pack the material in place and when the tubes are full the bar 5 is secured to the rods 2. In another method of making the plate a paste of red lead and sulphuric acid is filled into semi-cylindrical recesses 9, 10 in the two halves 11, 12 of a mould, Fig. 4. A rod 2 is supported at its ends in recesses 13 in the mould part 11 so that the rod extends axially along the cylinder formed by the recesses 9, 10. The two parts of the mould are then placed together and subjected to pressure. Pins and holes 14 ensure registration of the two mould parts. The pencil of active material surrounding the rod 2 is then removed and dried. A sheet of glass wool may then be wrapped cylindrically round the pencil, or a tape of glass wool may be wound helically round the pencil. The covered pencil is pushed into a tube 3 which is immersed for some days in dilute sulphuric acid and then dried. The plate is then built up from a number of pencils and tubes so produced.

Title: Process for the preparation of dicyclopentadienyliron
IPC: C07F17/02
Filed: 1953-10-27
Abstract: Cyclopentadiene is reacted with a pyrophoric ferrous oxide at a temperature of about 300 DEG  to 450 DEG  C. to produce dicyclopentadienyl iron.  The ferrous oxide may be obtained by heating ferrous salts of carbon-containing acids to their decomposition temperature. Specified salts include ferrous carbonate and the ferrous salts of unsubstituted aliphatic carboxylic acids containing up to 6 carbon atoms, e.g. formic and oxalic.  Mixed salts, e.g. ferrous cadmium, ferrous ammonium, ferrous zinc and ferrous tin oxalates may be used.  The decomposition may be carried out in an inert atmosphere, and it is preferred to pass the vaporized cyclopentadiene over the ferrous oxide as the latter is being formed. The process may be continuous.  In an example, ferrous oxalate dihydrate is heated to 350 DEG  C. in a tube in an atmosphere of nitrogen.  When no more water is evolved cyclopentadiene mixed with nitrogen is passed over the heated oxide, the sublimed product collecting in the cooler part of the tube.ALSO:Pyrophoric ferrous oxide is prepared by decomposing ferrous salts of carbon-containing acids by heat.  Suitable acids include carbonic acid and unsubstituted saturated carboxylic acids containing up to 6 carbon atoms (e.g. formic, oxalic).  Mixed salts, e.g. ferrous ammonium oxalate, ferrous cadmium oxalate, ferrous zinc oxalate and ferrous tin oxalate may be used.  The decomposition may be carried out in an inert atmosphere.  The pyrophoric ferrous oxide is used in the preparation of dicyclopentadienyl iron (see Group IV (b)).

Title: Improvements in means for converting electrical energy into sound
IPC: H04R1/28
Filed: 1934-10-17
Abstract: 447,749. Acoustic horns and resonators. VOIGT, P. G. A. H., 53, Church Road, Upper Norwood, London. Oct. 17, 1934, No. 29654. [Class 13] [See also Group XXXIX] In an arrangement for the conversion of electrical currents intc sound, the radiation of the sounds of low frequency is increased by simple longitudinal vibration of an air column in a resonator or "bass-chamber" of rigid construction which is free from openings near the node large enough tc introduce severe losses or to alter the fluidamental mode of vibration at a frequency determined solely by the length of the basschamber. The air column in the basschamber is excited at a distance from the antinode(s) by electromechanical means which do not seriously affect the mode of vibration and which are constituted, for example, by a diaphragm smaller than the sectional area of the chamber at the point of excitation coupled to a speech coil magnet system strong enough relative to the area of the diaphragm to damp it adequately and to prevent the diaphragm opening from acting as a large vent. The air column may be enclosed in a tube of circular or square cross-section, open at one or both ends, and the diaphragm is preferably mounted eccentrically with regard to the central axis of the resonator. As shown in Fig. 5, the resonator or bass-chamber 9 may be slightly tapered and the diaphragm may also operate a horn 8 of normal shape with a cut-off above the fundamental frequency of the "bass-chamber '' 9. Each side of the diaphragm driven by the actuating unit may be associated with a " basschamber," and, as shown in Fig. 7, a directly driven diaphragm 16 drives the air columns in the chambers 12, 13 whilst the sides of a second diaphragm 17 co-operate with the chambers 14, 15. The "bass-chamber" may be folded or re-entrant, and as shown in Fig. 4 may be thickened, as at x, to reduce losses at this point.

Filed: 1974-07-04
Abstract: 1519142 Magnetic card reader EMI Ltd 20 June 1975 [4 July 1974] 29663/74 Heading G4M A card, such as a credit card, bank note, or cheque having a magnetic layer arranged when magnetized to exhibit an inherent pattern of magnetization, e.g. by a suitable arrangement of acicular particles, is read by erasing the card, subjecting the layer to at least two different strength magnetizing fields measuring the relative remanent magnetizations in the pattern for each field. The card is fed along path 1 past a source 10 of an erasing field to a first station 20 which may be a permanent magnet applying a unidirectional field insufficient to saturate the layer. The card passes beneath a reader 30 which measures the remanence of the magnetized layer which will differ for areas of differently aligned particles. The reader may detect areas having a different remanence or may determine the position and/or size of the areas . The actual or relative levels of remanence may be determined. The card is then magnetized (40) by a unidirectional field of greater intensity and fed to a reader 50 which can measure and record the remanence levels or ratio and compare the result with that determined at 30 to see if a predetermined ratio is obtained. The card may be advanced along a guide slot in a reader by rollers (Fig. 3, not shown).
Patent GB-1006201-A (GB)
Title: Process for the production of foamed vinyl chloride polymers
IPC: C08J9/06
Filed: 1963-07-26
Abstract: Foamed plastics are prepared from plastisols of polyvinyl chloride or polyvinyl chloride copolymers of predominantly vinyl chloride content, using as a blowing agent an alkali metal borohydride with an organic compound having one or more hydroxyl groups in the molecule. Suitable hydroxyl compounds are mono- or polyhydric alcohols, amino alcohols, and hydroxy carboxylic acids, of up to 12 carbon atoms, and partial esters of the polyhydric alcohols with organic acids, which may be substituted, or have inorganic acid moieties. The preferred borohydride is sodium borohydride. Appropriate acids, or acid forming substances may be included to neutralize alkaline reaction products. The process is suitably performed by mixing a portion of the plastisol containing the borohydride with a second portion containing the hydroxyl compound, and gelling at elevated temperature; the hydroxyl compound:  borohydride molar ratio may vary from 0.5-8.0 mols.: 1 mol.  Examples are given for preparation of foamed plastics from polyvinyl chloride plastisols, using sodium borohydride and glycerol, ethylene glycol, butane triol, glycerol monoacetate, salicyclic acid, and di-sec-butyl phosphate.  The process is useful in that the hydroxyl compounds are fully miscible with the plastisol and have a conveniently low reaction velocity with the borohydride, which allows the addition of sufficient acid to give a neutral product of stable fine open cell structure. Specifications 799,750 and 847,504 are referred to.
