Title: Improvements in or relating to chewing gum
IPC: A23G4/08
Filed: 1941-05-19
Abstract: 555,083. Resins. HERCULES POWDER CO. May 19, 1941, No. 6439. Convention date, June 4, 1940. [Class 95] [Also in Groups VI and V] A chewing gum base is prepared by intimately mixing rubber or rubber-like material with hydrogenated rosin or hydrogenated abietic pimaric or other rosin acid, preferably at least 50' per cent. saturated. The hydrogenated rosin may be prepared by treating rosin in molten form or in solution in a volatile organic solvent with hydrogen in the presence of a catalyst, e.g. reduced nickel, at elevated temperature and pressure. Natural rubber, e.g. crepe or guayule, or rubber latex, synthetic rubber e.g. poly-, polychloro- or polymethyl-butadiene or latices made therefrom, gum chicle, factice or, preferably, chicle substitutes such as gutta percha, jelutong balata, gum tuno, namaqualand rubber, almeidana or euphorbia gum, abba rubber and inferior guttas, e.g. gutta siak, or mixtures thereof may be used. The ratio of rubber &c. to hydrogenated rosin is within the range of from about 20 to 1 to about 1 to 10, preferably from about 2 to 1 to about 1 to 2.5. The mixture may also comprise other resins, synthetic or natural, such as rosin, coumarone or Pontianak resin, ester, sweet-bay, spruce, Copal, Kauri or Damar gum or balsams, an oily softening agent, such as petrolatum, water white mineral or other petroleum oil, beef stearin, or cottonseed, olive or other vegetable oil or hydrogenated oil and a wax or wax-like material such as paraffin, candelilla, ceresin or bees-wax or stearic acid. The ingredients may be mixed by heating them together to a molten state with stirring but are preferably worked on a roll mill at temperatures below the melting point of the rubber &c. or the hydrogenated rosin. The wax and softening agent may be heated together and the rubber &c. and hydrogenated rosin stirred into the mixture. When a large proportion of wax is used, it may be heated with the rubber &c. and the hydrogenated rosin added. Rubber latex may be mixed with the other components before heating to evaporate the water. A small amount of water may be incorporated in the base particularly where the rubber is in solid form. In addition to sweetening and flavouring agents, fillers, such as clay, calcium or magnesium carbonate, magnesium oxide calcium or barium sulphate, or carbon black, or medicines such, as phenolphthalein or mannitol, may be included. Cocoa powder may be used as a filler and flavouring agent or cocoa syrup as a sweetening and flavouring agent if gum chickle is not present.

Title: Improvements in or relating to telephone systems and automatic switches for use therein
IPC: H04Q3/00
Filed: 1939-03-07
Abstract: 526,071. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., McCLEW, J. W., and CANNON, J. R. March 7, 1939, No. 7461. [Class 40 (iv)] Two polarized relays are connected across the outgoing end of a junction when a call has been extended to an operator's position and the calling party has hung up, the relays responding to signals of opposite polarity from the operator's position to control holding of the connection and re-ringing of the calling subscriber, respectively. The relays may also be connected during conversation to respond together to alternating current sent back over the speaking leads in series, as described in Specification 475,419, to effect metering in accordance with the duration of the call. Fig. 1 shows a discriminating selector-repeater at a satellite exchange, and Fig. 2 an operator's position at another exchange. When a call has been extended, in response to a particular digit, over junction 10, 11, relays MM, 2B operate to light the calling lamp LP, and ring- back tone RT is supplied over a winding of relay M to the calling party: Operation of sleeve relay SS removes the tone, reverses the incoming connections, and short-circuits relay MM so that marginal relay M operates. The calling party is requested to hang up and during the relapse of relay B, relay CJ operates to hold the connection and to bridge relays MH, RR across the junction. Relays M, 2B release during the holding time of relay B and extinguish the calling lamp. When B has fallen back, relay MH operates from negative battery in the operator's circuit to maintain CJ. The operation of key KRR to re-ring the calling party connects positive battery to the a-wire so that relay RR operates energizing RB to connect up ringing source GNR. When the subscriber again removes his receiver, relays A, B reoperate and relay OH is able to energize in series with low-resistance relay I to complete a local circuit for relay M. Relay 2B is reoperated and the calling lamp relit. During conversation, relays MH, RR are connected through condenser QA across the junction and both will respond to A.C. metering signals to short-circuit relay Q. The release of relay Q re-sets the usual delayed-metering relays for a further operation. Contacts NP are provided to short-circuit relay D and prevent ordinary metering, but may be omitted for special manual-board calls, e.g., for " time " and " phonogram calls, which are characterised by a special digit. The provision of the two relays M MM prevents the circuit becoming locked up if the subscriber releases before the operator replies. Normally rectifier MRA is conductive and MRB not, but when the operator replies and the current is reversed through relay SS, the relay D allows metering against the calling party.

Title: Improvements in or relating to the recovery of sulphur from sulphurous gases
IPC: C01B17/04
Filed: 1935-03-11
Abstract: In the treatment of gases containing sulphur dioxide, e.g roaster gases, the sulphur dioxide is oxidized to sulphur trioxide, sulphuric acid or fuming sulphuric acid, which is then separated from any other gases present.  The sulphur trioxide &c., is then reduced to sulphur in a single operating stage by means of hot carbon or carbonaceous reducing agents, or by means of gaseous reducing agents, e.g. hydrogen, carbon monoxide, methane, or other hydrocarbon gas or vapour at temperatures of about 500--800 DEG  C.  When using a gaseous reducing agent, the reactants may be preheated, separately or together, and the reaction is assisted by brickwork or iron oxide or similar catalysts.  The formation of byeproducts such as carbon bisulphide and carbon oxysulphide may be controlled by the proportions of the reactants and by passing the hot gases through catalysts such as iron oxide or alumina.

Title: Improvements in or relating to apparatus for moving a vertically reciprocating mould in bottle blowing machines
IPC: C03B9/20
Filed: 1928-03-12
Abstract: 287,067. Hillmann, H. March 10, 1927, [Convention date]. Blowing. - Relates to a bottle-blowing machine of the kind described in Specification 172,947 in which a parison is transferred from a parison mould to a finishing mould by means of the ring mould, which reciprocates vertically between the two moulds. According to the invention, the means for reciprocating the ring mould is so constructed that the mould descends to a fixed lower level while its upper level is determined by the position of the parison mould. The machine gathers charges of glass by suction from a mass of molten glass contained in a tank A. The moulds are carried bv a frame 1<1> which rotates about a fixed central column 1. The finishing moulds 3 are carried by brackets 2 adjustably secured to the frame 1<1>, and the parison moulds 4 are supported by carriages 7 which are reciprocated in vertical guides on the frame. Each mould carriage 7 is connected by a link 25 with a lever 23 which is rotatable about a shaft 12, a spring 28 being interposed to form a resilient connection between the link and the lever. A segmental cam member 22, also mounted on the shaft 12, is rigidly connected with the lever 23. The ring mould 8 is supported by a carriage 18 which slides in vertical guides on the frame 1<1> and is connected by a link 16 with a lever 14. This lever is pivoted at 13 to a two-armed lever 11 and has a central roller 21 which rests on the segmental cam 22. The lever 11 is pivoted on the shaft 12 and carries a roller 10 which runs on a cam 9 fixed to the central column 1. In use the ring mould rests on and moves with the parison mould, when the latter dips to gather a charge, since the roller 21 rests on the upper side 33 of the segment cam 22. When the parison mould opens, the cam 22 remains stationary, and the roller 10 moves inwards along the cam 9. The arm 11 and the pivot 13 thus rise. the roller 21 runs off the top of the cam 22 and moves down the circular face 34, and the ring mould 8 descends on to the finishing mould 3. When the parison mould is changed for one of a different height, the highest position of the ring mould adjusts itself to a new level since the roller 21 rests on the upper side of the cam 22 which is fixed in relation to the mould carriage 7. The device enables the ring mould to be moved by a fixed cam, 9, irrespective of the length of the parison mould.
