Filed: 1952-03-24
Abstract: 697,380. Tyre vulcanizing presses. ZAENGL, K. March 24, 1952, No. 7468/52. Addition to 694,820. Class 87 (ii) A tyre vulcanizing press as described in the parent Specification, in which the upper part of the press is freely suspended from a double lever pivoted to the lower part and the suspension and pivot points are in an approximately horizontal plane when the press is closed, is modified in that the double lever d d' is adjustable, mounted within its bearing e and in addition to the raising and lowering movement of the upper mould part a also carries out simultaneously a displacing movement on the tyre h, so that this is loosened before the opening of the mould and the newlyintroduced tyre is centred before the closing. As described in the parent Specification, the press is opened from the closed position shown in Fig. 1 by admitting compressed air to the oil pressure cylinder m, but at the same time compressed air is admitted to an auxiliary cylinder c<SP>4</SP> (bolted to the arm d of the double lever) and forces its piston outwards. The piston rod of the auxiliary cylinder is linked by an arm s' to an eccentric e' on which the double lever d d<SP>1</SP> is pivoted and it therefore displaces the eccentric on its outward stroke and moves the double lever a small distance horizontally, so loosening the tyre, Fig. 2. Since a lower pressure suffices for the auxiliary cylinder than for the oil pressure cylinder, the piston in the former is operated first, and the air pressure does not build up in the cylinder m quickly enough to drive the oil into the main cylinder c and cause the press to open before the loosening movement is completed. On closing the press, the movements occur in the reverse order.

Single coin receiving apparatus, e.g. for a telephone call-box, comprises a gauge plate 2 with slots 2a, 2b, 2c, for coins of different sizes, leading to channels 1a, 1b, 1c, guiding coins into a way 4, coins of adequate diameter rolling against guides 3a, 3b, 3c and behind a partition 5 to a coin shoot 8, whilst too small coins fall over and are deflected by partition 5 to a return shoot 7. Balls are located below and between adjacent slots 2a . . . 2c, so that while one coin is being inserted, the remaining slots are obturated, Fig. 3 (not shown). The first coin M falling down shoot 8 rests on a tongue 9b of the armature 9a of electromagnet 9, so as to rest against stop 11 and to lie diagonally across shoot 8. Any further acceptable coins ride over coin M into the return shoot. Any ferromagnetic disc is deflected upwardly by permanent magnet 6 so as to pass straight into the return shoot. A coin collection signal from the exchange energizes electromagnet 9, so that the coin falls on to ledge 9c of the armature, to operate one of switches 10a, 10b, 10c, to signal the value of the coin to the exchange. On de-energizing the magnet, the coin passes to a collection shoot 8b. Replacing of the handset withdraws stop 11, so that an unused coin passes to the return shoot 7.
Patent GB-471927-A (GB)
Title: Improvements in or relating to synthetic resins
IPC: C08L67/00
Filed: 1936-03-13
Abstract: Synthetic resins are prepared by condensing a phenol-carboxylic acid with a methylene-containing agent in the absence of a catalyst or in weakly acid or alkaline conditions and reacting the product with a polyhydric alcohol.  Alternatively, the phenol-carboxylic acid, the methylene-containing agent and the polyhydric alcohol may all be reacted together.  The compatibility with oils may be improved by combining with the resin at any stage or stages a modifying agent such as a natural resin, fatty oils or fatty acids.  Modifying agents which may also act as plasticizers include castor oil, linseed oil, tung oil, cottonseed oil, coconut oil, soya bean oil or the corresponding fatty acids, blown or polymerized oils, rosin, abietic acid, dibutyl phthalate, tricresylphosphate, acetanilide, toluene sulphonamide, and ethyl or methyl phthalylglycollate.  The products with or without the addition of metallic driers and oil-soluble synthetic resins such as phenylphenolformaldehyde condensation products may be used in oil or cellulose ester coating compositions. In examples: (1) a phenolcarboxylic acid such as salicylic acid, cresotinic acid, dihydroxybenzoic acid, gallic acid, hydroxyphthalic or hydroxynaphthoic acids is condensed with a methylene-containing body such as formaldehyde, paraform, hexamethylenetetramine, furfurol, acetaldehyde or acetone in the presence, if desired, of a weak or dilute acid such as oxalic acid, and the product is interacted with (a) a polyhydric alcohol such as glycerol, polyglycerol, glycol, ethylene glycol or pentaerythritol, (b) a mixture of abietic acid and glycerine, (c) firstly a polybasic acid such as phthalic anhydride, maleic acid or succinic acid and after with glycerine, or (d) a mixture of castor oil and glycerine, to yield a resinous product; (2) p-hydroxybenzoic acid or p-cresotinic acid is condensed with formaldehyde in the presence of oxalic acid, or salicylic acid is condensed with formaldehyde in the presence of lime, and the products are interacted with a mixture of rosin and glycerine; (3) p-hydroxybenzoic acid is condensed with formaldehyde in the presence of oxalic acid and the product is heated with rosin and then with phthalic anhydride, glycerol and linseed oil, tung oil or sunflower seed oil fatty acids.

Heading A4K In order to ensure that no wire bristle filaments, in the form of flat strips, are presented to a tufter in a position which would necessitate edgewise bending, the leading ends of continuous filaments are assembled into overlapping relationship before a cutter operates to sever the tufts. As shown, four filaments 7 are fed, in side-by-side relationship, by rubber covered rollers 11, 12 intermittently driven by gear wheel 18 operated by crank arm 20, when this is oscillated in one direction by eccentric 24. On emerging from guide 6b, the filaments are deflected, by guide 27, from a side-by-side to a superposed face-to-face relationship. At the end of a feed stroke, the filaments are cut by knife 30 operated by lever 34 and cam follower 34a. Guide 27 is movable in the same direction as knife 30 by means of a lost-motion connection therewith. The severed tuft is accordingly lowered into notch 33 of picker bar 4a. Bar 4a co-operates in the usual way with a tuft inserting tool. Parts of the apparatus are adjustable or interchangeable to suit various cross-sections and lengths of bristle. The assembled tuft may alternatively be delivered to a collecting hopper.
