Title: Improvements in or relating to card-index apparatus
IPC: B42F17/00
Filed: 1954-05-03
Abstract: 764,969. Filing papers ; indexing. EVE, J. H. S. and CARTER-PARRATT, Ltd. Aug. 3, 1955 [May 3, 1954], No. 12796/54. Classes 16 and 146(1). A card index device comprises main divider plates having upstanding window-pieces extending across the whole width of the plate through which can be seen tabs on intermediate divider plate, which tabs carry identification symbols, are of substantially the same height as the window-pieces and have a progressively staggered relation. As shown, banks A, B of cards 3 are divided by main plates 1, each bank being sub-divided into subsidiary banks A<SP>1</SP>, A2, A<SP>3</SP> by intermediate plates 2, the cards 3 being held in overlapping relation in each bank as by lugs thereon engaging between rods in the bottom of the box or tray. Each plate 1 has its top marginal part bent over and upwardly to form a channel 4 which holds the windowpiece 5. A central tab 6 is secured over the window 5 to show a label strip through a window 7. The sides of the plates 1 are strengthened by housings 1a in which are fitted top and bottom blocks 9 and 10 (not shown) each block having a stem portion 9a held in the housing 1a by an indentation 11. The block 9 is slotted to receive the end of the window 5, and the block 10 has a curved bottom face to act as a fulcrum. Each plate 2 has a tab 12 secured thereto, with a window 13 to show a label slip. As shown, the staggering of the tabs 12 is effected by providing narrow width plates 2 each with a central tab 12, the plates 2 being staggered and secured in position by lugs engaging between the rods in the bottom of the box or tray. As in Fig. 8, the tabs 12 may be slightly higher than the window 5, so that a finger 17 will easily engage the required tab 12 and window piece 5 to pivot both forwardly. As shown in Fig. 7, the tabs 12 may be provided with a movable signal 14 having a finger grip 15, which can be moved over the slip showing in the window 13 to impart any warning such as the fact that a card has been removed. The strips 5 and the tabs 12 may be inclined rearwardly.

Title: Improvements relating to the production of coatings on metal surfaces
IPC: C23C22/14
Filed: 1941-10-03
Abstract: 551,261. Modifying metallic surfaces. PYRENE CO., Ltd., (Parker Rust-Proof Co,.). Oct. 3, 1941, No. 12821. [Class 82 (ii)] Coatings are produced on metal surfaces by an acid phosphate solution containing a nitrate or nitrite or both and at least one chlorate. The solution, generally containing zinc dihydrogen phosphate, is sprayed on to the surface at a temperature of 115-180‹F, the pH value of the solution being maintained at 2.5-2.9 by the continuous addition of a neutralising agent such as sodium, hydroxide, and the solution circulated and resprayed. The solution may also contain a copper compound, e.g. copper carbonate, as an accelerator and the coated surface may be treated with chromic acid. In an example, the production of a coating solution from zinc oxide, nitric and phosphoric acids, sodium chlorate and copper carbonate is referred to. Instead of zinc phosphate, other phosphates such as of manganese may be used. Specifications 346,401, 386,739 and 514,443 are referred to.

Abstract: 792,918. Coaxial-line terminations. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 2, 1956 [May 4, 1955], No. 12890/55. Class 40 (8). A coaxial line 1, 2 is provided with a termination or attenuator consisting of a cylinder 3 of lossy material which is tapered at one or both ends in such a manner that incident energy first meets a relatively small portion of the periphery of the cylinder in a region of weak field strength. To prevent reflection of energy at the entrance to the bore provided for the inner conductor, the leading edges of the bore may be rounded or countersunk as indicated at 6 in Fig. 3. The tapered section should have a length of about one half-wavelength. The cylinder may be formed of a polyester loaded with graphite or an ethoxyline resin loaded with carbonyl iron dust. Alternatively, it may be made of hardwood.

Abstract: 1305924 Retreading tyres H TIES 19 March 1970 [19 March 1969] 13421/70 Heading B7C A machine for handling tyres, during for example retreading, (the right hand half being shown in Fig. 1) comprises a pair of rim plates 2 each mounted on a respective rotatable shaft 5, which shaft can be moved longitudinally towards or away from each other, the awayward movement being limited by the end surface 9 of each shaft abutting a spacer member 6 whose position is adjustable in the direction of the shafts. The spacer member is screwable axially into a holder 7 to provide the adjustment of the abutting position, the spacer and holder being located at one end of a cranked lever 11 which can pivot about its apex under the action of a piston and cylinder unit so that the spacer member 6 can be swung out of the path of the shaft 5 and allow the rims to be separated beyond the limit set by the abutment when it is desired to position a tyre between the rim plates 2. Eaoh shaft 5 is slidably housed in a respective casing 32 which have their orientation adjustable for alignment with each other and the machine frame by means of bearings 30, 31. Longitudinal movement of the shafts is effected by a cylinder 43 with a piston and a rod 45 which is freely attached to a frame plate 19. After a tubeless tyre has been positioned the rim plate shafts are moved towards each other to engage the tyre beads and the spacer members are returned to their operating position where they limit outward travel of the shafts: air is supplied to the tyre via a pipe 3 and the pressure in the tyre acts on the rim plates to move them apart until the end surfaces 9 abut the head 6b of the spacer member. The adjustment of the spacer member enables tyres of different axial widths to be accommodated and the head 6b may be aligned with a scale (28) graduated according to tyre sizes. The member 6 can be locked in a chosen position by a sprung pawl (24).

Title: Improvements in ion exchange resins
IPC: C08F8/00
Filed: 1954-05-07
Abstract: Copolymers are prepared from a monovinyl aryl compound or a monovinyl heterocyclic compound having an active hydrogen substituent, and a divinyl ring-containing nitrogen heterocyclic crosslinking compound such as a divinyl pyridine, alkyl pyridine, quinoline, isoquinoline or pyrrole.  The monovinyl aryl compound may be styrene, ortho-, meta- or paramethyl or ethyl styrene, vinyl naphthalene or vinyl anthracene, or a vinyl substituted phenol or hydroquinone.  The monovinyl heterocyclic compound may be 2-methyl-, 2-ethyl-, 3-methyl-, 2,3-dimethyl-, or 2-methyl-3-ethyl-5-vinyl pyridine, 2-methyl-5-vinyl or 4-methyl-4-vinyl quinoline, 1 methyl- or 3-methyl-5-vinyl isoquinoline, or other vinyl substituted alkyl derivatives of nitrogen-containing heterocyclic compounds, or a vinyl methyl thiophene or furan.  The crosslinking compound is preferably divinyl pyridine, usually utilized as mixtures of the o-, m- and p-isomers.  Polymerization may be effected in aqueous suspension in the presence of a catalyst such as ozone, oxygen, acetyl, benzoyl or hydrogen peroxide, tertiary butyl hydroperoxide, a water-soluble persulphate, azobisisobutyronitrile or azo biscyclopropiopropylnitrile to produce beads of copolymer. Anion exchange resin may be prepared from the above copolymers by (a) haloalkylation followed by amination; (b) where the copolymer is prepared from an alkyl monovinyl compound, by halogenation, e.g. by the method described in Specification 744,386, followed by amination; or (c) where the monovinyl constituent of the copolymer is other than a monovinyl aromatic hydrocarbon, by condensation with an aliphatic aldehyde containing not more than 3 carbon atoms and ammonia or a primary or secondary amine.  The ion exchange properties may be enhanced by quaternization of the nitrogen of the heterocyclic ring, e.g. by treating with methyl chloride or iodide.ALSO:2,4-divinyl pyridine is prepared by condensing 2,4-dimethyl pyridine with formaldehyde and diethyl amine to produce 2,4-(b -N,N-diethylaminoethyl) pyridine which is then distilled to convert the diethylamino-ethyl groups to vinyl groups, or, alternatively, by condensing 2,4-dimethyl pyridine with formaldehyde to produce the corresponding 2,4-diethanol pyridine, which is then distilled over an alkali, such as potassium hydroxide, when 2,4-divinyl pyridine is produced.  Other divinyl pyridines may be produced by employing other dimethyl or trimethyl pyridines as starting materials, and the process may also be used to produce divinyl quinolines, isoquinolines or pyrroles.
