Title: Improved method and apparatus for the hydrogenation of crotonaldehyde
IPC: C07C29/17
Filed: 1928-08-22
Abstract: 321,253. Horsley, G. F., and Imperial Chemical Industries, Ltd. Aug. 22, 1928. Butyraldehyde and butyl alcohol are produced by the hydrogenating of Crotonaldehyde, the Crotonaldehyde and hydrogen being exposed gradually to reaction conditions, for instance by mixing the reactants gradually in the presence of the catalyst. One or both of the reactants may be mixed with diluents such as steam, and crotonaldehyde mixed with some hydrogen may have excess of hydrogen added progressively. The apparatus consists of concentric tubes 2, 3, the inner tube being perforated, and the annular space being packed with catalyst 4 which may be metallic copper and nickel oxide supported on asbestos, while the inner tube 2 may be packed with asbestos to give the same resistance to the gases as the catalytic mass. The outer tube is initially heated to 120‹ C. by means of a steam or oil jacket. Crotonealdehyde vapour mixed with steam is admitted by a tube 6 and hydrogen by the tube 3. The temperature is maintained at 100-120‹ C. by circulating hot water or oil in the jacket, the reaction being exothermic. For making butyl alcohol it is preferred to use three times the theoretical quantity of hydrogen. Specifications 10724/11, 283,887 and 291,253, [all in Class 1 (i), Chemical processes &c.], are referred to.

Filed: 1927-09-14
Abstract: 299,955. Siemens Bros. & Co., Ltd., and Humphries, H. E. Sept. 14, 1927. Automatic and semi-automatic exchange systems.-In key-controlled senders having provision for cancellation by the operator of a number set up, the cancellation of a number so far set up is effected automatically if more than one key is operated at the same time. A tone or visual signal may be given in addition to the cancellation. As shown in Fig. 1, each digit key is provided with contacts additional to those, shown unconnected, which operate relays in register senders. The contacts of the " odd " and " even " keys are connected to the windings of a relay CZ which is unaffected by current through one winding only. If adjacent keys are depressed simultaneously, CZ operates and at cz closes a circuit for cancelling relay CR in parallel with the usual cancelling key CK. In a modification, Figs. 2 and 3 (not shown), two separate relays may be provided for the " odd " and even " keys and the circuit CR includes contacts of both relays, the relays being normally unoperated or operated according as to whether the additional key contacts are " make " or " break " contacts respectively. In another arrangement, Fig. 4 (not shown), the " odd " and " even " keys are connected through resistances to a marginal relay, or a resistance individual to each key may be provided it it is desired to detect simultaneous depression of any two keys. In another arrangement, the moving contacts of the " odd " keys are connected to one pole of battery and the moving contacts of the " even " keys are connected through a common wire and relay to the other pole of battery, the other contacts being joined together. In the arrangement shown in Fig. 5, additional key-contacts are dispensed with, the windings of relay CZ being included directly in the circuits of the digit-recording relays DR, DR1. A tone or visual signal circuit may be closed by contacts of relay CZ.

Title: Credit unit
IPC: G07F5/22
Filed: 1961-07-05
Abstract: 941,207. Coin freed phonographs. AMI (INTERNATIONAL) S.A. July 5,1961 [July 11, 1960], No. 24338/61. Heading G4V. A coin-freed phonograph has a credit unit comprising a ratchet wheel 51 driven by a solenoid 61 to register three different coin values, a reversely driven ratchet wheel 52 fast on the same shaft as wheel 51 being driven by a solenoid 101 to cancel credit according to the records played. Four coin operation is provided, contacts CS-1, Fig. 11, detecting the highest denomination and causing solenoid 61 to be energized. A ratchet engages the wheel 51 and rotates it to the extent permitted by arm 76 and a fixed stop 23, Fig. 9. The next highest denomination of coin is detected by contacts CS2 which energize solenoid 83 as well as 61 and the wheel 51 rotates only so far as a stop projected by solenoid 83 into the path of arm 76. The lowest acceptable coin value may be a single coin detected by contacts CS-3, or two coins with a deflector F which allows the first coin to pass contacts CS-4 and the second to operate the contacts. Receipt of this value in either case operates solenoid 81 as well as solenoid 61 and the ratchet wheel 51 rotates to a point where arm 76 engages a stop positioned by solenoid 81. The positions of the fixed stop 23 and of the solenoid 83 are adjustable to adapt the apparatus for registration of different ranges of coinage. Cancellation of credit is commanded by operation of a contact E in the phonograph should a record of one type be selected, or by operation of contacts E and S should another type be selected. With contacts E operated a solenoid 101 is energized to rotate the cancellation ratchet wheel 52 to a maximum extent allowed by a fixed stop, positioned at point 117, 118, or 119, according the scale of charges in force. With contacts E and S operated solenoid 122 is energized as well as 101 and the cancellation wheel 52 is rotated only so far as arm 113 is permitted by a stop positioned by solenoid 122. The solenoid 122 is adjustably mounted to permit variation of the scale of charges. Control of the phonograph is by way of contact strips on an insulating board 25, the strips being interconnected by wiper blades 41 on an arm 42 of shaft 46.

DUNLOP RUBBER CO., Ltd., 31, Osnaburgh Street, London, ANODE RUBBER CO., Ltd., 10, Lefebvre Street, St. Peter's Port, Guernsey, and HEMM, C., 2, Cambridge Street, Manchester. Aug. 29, 1931, No. 24340. [Class 41.] An anode mould for the manufacture of a rubber or like article by electrophonetic deposition comprises a number of insulated sections to which connection is made independently. A mould for the deposition o f a Wellington boot comprises sections 1.. 5, Fig. 4, separated by insulation 6. The sections are connected by bolts 11 and nuts 12 which may form part of electric connection to one section, being insulated from the other. The heel section 14 is readily detachable from its base for lining with fabric. The heel part of the deposited boot is formed as a hollow into which an ordinary moulded heel may be cemented after partial or complete drying. Alternatively an ordinary rubber sole and heel may be cemented on to a body formed by electrodeposition. In the modification, shown in Fig. 3, after deposition to the thickness indicated at 8 a gauze sheet 9 is applied in contact with the stud 7 thus enabling the thickness to be built up as indicated at 10. The projecting part of the stud 7 is covered with a rubber sheath during the first stage. The mould is preferably covered prior to deposition with a wetted stocking of textile material which subsequently constitutes the lining of the boot. The insulating material may be keyed into recesses in the anode sections so as to hold them together or it may form the main body of the mould, the anode sections being inlaid. In the latter form, anode sections which have become thin in use may be replaced. Fabric for reinforcement may be introduced at any stage of the deposition. Deposition may be effected from natural or artificial aqueous dispersions of rubber, guttapercha or balata, with or without the addition of aqueous dispersions of synthetic rubber, rubber reclaim, rape oil, vulcanized oils, cellulose esters or ethers or proteins such as casein. Deposition may also be effected from aqueous dispersions of synthetic rubber with or without compounding ingredients. The dispersions may be compounded and/or concentrated. They may contain vulcanizing agents and accelerators, colouring matter, preservatives and softeners and fillers such as clay, barium sulphate, lithopone, lampblack, gas-black, zinc oxide and ebonite.
