Title: Improvements in or relating to time-division multiplex telecommunications exchange systems
IPC: H04Q11/04
Filed: 1965-01-27
Abstract: 1,086,200. Automatic exchange systems. SIEMENS A.G. Jan. 27, 1965 [Jan. 28, 1964], No. 3538/65. Heading H4K. In a T.D.M., P.B.X. utilizing respective circulating stores for holding the addresses of the calling and called parties, an extension engaged in an exchange call can initiate an interim call or call transfer by depressing a key at his substation. A free time slot is allotted to the interim party and speech stores are utilized for " connecting " the calling extension and the interim party together during their respective time slots. Release of the interim call and transfer by the caller are not described. Transfer by the interim party is initiated by depression of a key at his subset. After transfer the same time slot is used by the exchange line and the new extension. This is achieved by transferring either the exchange line address or the extension's address from its original time slot to that already in use by the other. At the initiation of an interim call, a digit receiver, free time slot and a speech store must be available, otherwise engaged tone is returned. The digits of the interim party are transferred one at a time from the digit receiver to a register during the original time slot and are then passed to either the calling or called party store (the same store as that containing the extension is normally used) during the newly allotted time slot. Engaged tone is always reverted whenever the register is occupied. Only one call transfer at a time can be made. A store UM may be provided for containing the address of a subscriber to be called in the event that a particular called party is absent from his station (i.e. call diversion) (details of this system are however not given). Again, the central control allows for the possibility of operator break-in but no details are divulged.

Title: Process for the manufacture of methylamino-methyl-(3-amino-4-hydroxy-phenyl)-carbinol and derivatives thereof
IPC: C07C215/76
Filed: 1944-02-29
Abstract: Methylaminomethyl - (3 - amino - 4 - hydroxyphenyl)-carbinol and its acyl derivatives of the formula <FORM:0575644/IV/1> where R and R1 represent hydrogen or an acyl radical are prepared by the hydrogenation of the corresponding 3 - amino - 4 - hydroxy - o  - methylamino-acetophenone.  The hydrogenation may be carried out on either the acylated or the non-acylated compound, and if the acyl compound is prepared it may, if desired, be hydrolysed.  If the reduction is carried out in the presence of an optically active acid such as tartaric acid, salts of optically active bases can be directly obtained.  The N.N1-diacyl compounds are easily water soluble and are no longer capable of forming salts with acids but will do so with bases.  In examples: (1) 3 - Amino - 4 - hydroxy - o - methylamino - acetophenone tartrate is shaken with hydrogen under a pressure of 0.2 atmospheres, in the presence of platinum oxide.  The catalyst is removed, and the product which consists of l - (+) - methyl - aminomethyl - (3 - amino - 4 - hydroxyphenyl) - carbinol tartrate.  (2) 3-Amino - 4 - hydroxy - o  - methylamino - acetophenone hydrobromide is acetylated with acetic anhydride to 3-acetamino-4-hydroxy-o -methylamino-acetophenone hydrobromide which is then hydrogenated as in example (1) to form methylaminomethyl - (3 - acetamino - 4 - hydroxy - phenyl) carbinol hydrobromide; (3) 3-Amino - 4 - hydroxy - o  - methylamino - acetophenone tartrate is acetylated with acetic anhydride, and hydrogenated as in example (1) to form acetylmethylaminomethyl - (3 - acetamino-4-hydroxyphenyl)-carbinol.

As shown, the means for manually moving brush 82 comprises a knob 18 geared at 24 to a toothed sector plate 50 carrying the brush 82. The rotary surface is preferably a disc 90 with a star-shaped element 96 continuously engaged by wiper 104b, but may comprise a drum with a suitably configured conductive insert on its periphery. To avoid stalling of the motor at low speeds and difficulty in starting if brush 82 is not in contact with element 96 when it is at rest, a centrifugal switch interconnects the brush 82 and element 96 below a given slow speed. This switch comprises an arm 124 (Fig. 4) carried on a metal post 94 extending up from element 96 and a ring element 102 connected to brush 82 via sector plate 50. When the motor is running above a given slow speed the arm 124 lifts (as shown by broken lines) and the brush 82 is then effective as a speed controller.

Title: Electric cells
Inventor: LINTON ALFRED
IPC: H01M10/34
Filed: 1963-04-04
Abstract: 1,088,271. Sealed alkaline electrolyte secondary cells. BURNDEPT Ltd. April 7, 1964 [April 4, 1963], No. 3904/63. Heading H1B. In a sealed, alkaline electrolyte, secondary cell which is designed to deliver substantially its whole theoretical capacity in not more than two hours, the negative electrode system has a greater theoretical capacity than the positive, and, at the moment of sealing, the positive electrode system has material in the uncharged state, while the negative electrode system has a main body of uncharged cadmium oxide or hydroxide, together with such a reserve of charged cadmium metal that the total charge on the negative electrode system exceeds that on the positive. If desired an additional reserve of charged material may be included in the negative electrode to compensate for deterioration of the electrode during its lifetime. Preferably the action materials on the electrodes are bound with elastomers, e.g. polyisobutylene. The active materials of the positive electrode may be nickel, nickel hydroxide and a small proportion of cobalt hydroxide. Graphite may also be included. The negative electrode contains calcium oxide, nickel powder, and if desired graphite and iron oxide. The mixtures may be coated on to nickel gauge or expanded foil. The electrodes may be of sintered construction. The negative electrode system may be prepared as two strips one for the main body and the other an auxiliary electrode for the reserve of charged material. Strips of positive electrode material 10, separators 16, 18, main negative electrodes 12, and auxiliary negative electrodes 14 are superimposed and wound on a slotted mandrel into a spiral which is enclosed in a can 20 between insulating end discs 22, 24, which are apertured to allow contact strips 26 and 28, 29 to pass through from the electrodes and be connected to the terminals 30, and the bottom of can 20. The auxiliary negative electrode is fully precharged before incorporation in the cell. In a modification the slotted mandrel is applied to the middle of the pack of electrode strip and separators. A button cell construction is also described with the electrodes and auxiliary electrodes and separators as superimposed flat plates. A safety device to prevent bursting of the cell if gas pressure accumulates may consist of a diaphragm structure across the top of the electrodes with an inturned pointer by constituting a piercer on the top cap of the cell. If cells are to be connected together as batteries, overdischarge of a weak cell can be avoided by connecting an auxiliary electrode of uncharged negative material to the positive electrode.

Title: Processes of Producing Metallised Brushes for Electric Machines.
IPC: H01R43/12
Filed: 1917-03-20
Abstract: 127,030. Compagnie GÚnÚrale Electrique. May 22, 1916, [Convention date]. Brushes.-Brushes for electric machines are made from a metal in an extremely fine state of subdivision by coating the metal with an organic agglutinant, desiccating the product obtained, compressing it, and then heating it to a high temperature to carbonize the organic matter. In a modification in which the brush is to be formed of a metallic alloy, the metals in a very finely powdered state are caused to unite by submitting the mixture to a high temperature and to a high pressure in a reducing-medium. The powder thus obtained is mixed with charcoal powder and with a certain quantity of one of the constituent metals in a finely powdered form and the mixture heated in a closed container, or the alloy mav be treated in an analogous manner to that for obtaining brushes from a single metal.

Patent GB-372797-A (GB)
Title: Improvements in or relating to the treatment and manufacture of textile materials
IPC: D06M11/13
Filed: 1931-02-10
Abstract: Staple fibres are treated with a highly concentrated solution from which a roughening substance is deposited on to the surface of the fibres, said roughening substance being capable of ready removal without modification of the material of the fibres.  The solution used may be a solution of the roughening substance itself, or the roughening substance may be precipitated from the solution by chemical means.  According to a modification, the fibres may be subjected to the vapour of a sublimable substance. Examples of suitable roughening substances are substances capable of forming solutions of 10 per cent strength and upwards, for example, ammonium or barium chloride; barium, potassium, or sodium nitrate; aluminium, ammonium, iron, magnesium, potassium, or sodium sulphate; zinc sulphate; sodium carbonate and the carbonates and bicarbonates of potassium and ammonium; sodium phosphate; sodium hydrogen phosphate; sodium borate; the alums for example potash alum; boric acid; barium, calcium, and lead acetate; potassium and sodium oxalate; Rochelle salt; tartar emetic; naphthalene; benzoic, citric, phthalic, salicylic, and tartaric acids.  Aqueous or organic, for example alcoholic solutions may be used.  As an example of a substance which may be formed by chemical action, lead chloride is mentioned.  The roughening substance is readily removed by means of the solvents by which they were applied; lead chloride may be removed by hot water. The process may be applied to fibres of all kinds, for example, fibres of cellulose esters or ethers, reconstituted cellulose such as viscose, nitrocellulose, and cuprammonium fibres, or natural silk fibres.  The roughening substance may, if desired, be applied to the filaments from which the staple fibres are to be made.  The amount of substance applied is comparatively small, for example 2 per cent or thereabouts of the weight of the fibres.  The fibres so treated have a reduced tendency to slip during spinning.
