Title: Improvements in or relating to moulding presses
IPC: B30B11/10
Filed: 1947-07-04
Abstract: 627,154. Rotary table moulding - machines. STEAD & CO., Ltd., J., JOHNSON, H. R. S., and WALKER, S. July 4, 1947, No. 17620. [Class 87 (ii)] An annular table 3 with lower moulds 27 round its periphery is rotated so as to bring them in turn into register with a common upper mould 25 carried by the ram 24 of a press and electrically heated plates 10 are applied automatically, by the operation of the ram, to the underside of the table beneath the lower moulds not so in register so that heat is conducted to the lower moulds through the table. During the moulding in the press the operations of charging, positioning inserts &c. are performed on those lower moulds not in the press. Each hot plate 10 is guided between uprights 11 and has a stem 12 whose lower end is guided at 13 and which has a collar 15 against which a spring 14 bears, the bottom of the spring pressing against the end of a lever 17 pivoted at 18. The other ends of the levers 17 meet at a coupling 19 beneath the centre of the table, and the coupling 19 is depressed by the end of a lever 20 which is in turn depressed by a cross-bar 22 when the ram is lowered, the cross-bar being connected to the ram by rods 23. When the ram is raised the hot plates 10 leave the underside of the table 3 by their own weight, and when it is lowered they are pressed against it through the springs 14. To prevent lowering of the ram when a lower mould is not in register with the upper mould the table 3 has a notch near each lower mould which a catch 29 enters when the moulds are in register, but when they are not the catch obstructs the control lever 31 of the valve box 32 for supplying hydraulic fluid and prevents it from being operated to lower the ram. The table may be rotated by power, in which case the power connection may be interlocked with the press mechanism, or may be supported on ball or roller races and rotated by hand. The moulds on the table may be at different heights to operate with a press with more than one opening. The Provisional Specification states that the plates 10 may be heated by steam or oil from a central distributing box.

Patent GB-458475-A (GB)
Title: Dialkyl glycols and their manufacture
IPC: C07C31/20
Filed: 1935-06-20
Abstract: Solid symmetrical dialkyl derivatives of ethylene glycol are produced by reducing keto-alcohols produced from esters of fatty acids having 12 or more carbon atoms in the acid radicle as described in Specification 454,238.  Two isomers, probably stereoisomers, exist, differing in melting-point, and the yield of either may be favoured by modifying the reaction conditions.  The keto-alcohols may be reduced in amyl alcohol solution by an alkali metal or alkali metal amalgam or by means of hydrogen under pressure in presence of a hydrogenating catalyst.  Higher temperatures such as 175--250 DEG  C. favour the production of the lower melting or meso form which also chiefly results from alkali-metal reduction at any temperature.  The higher melting racemic forms may be made by hydrogen reduction at below 100 DEG  C. such as 20--25 DEG  C.  Suitable catalysts are heavy metals and their oxides and salts, such as platinum oxide and reduced nickel.  The two forms of the products may be separated by fractional crystallization from aromatic hydrocarbons such as toluene and benzene.  The initial keto-alcohols may be made from fatty acids or their esters or natural glycerides, which latter may be converted into the methyl esters separated by fractional distillation reacted with alkali metal and hydrolyzed to yield individual keto-alcohols or the mixed methyl esters may be converted into mixed keto-alcohols. The keto-alcohols need not be isolated, thus an ester may be reacted with sodium to produce a keto-alcohol, alcohol and more sodium being then added to produce the glycol.  In examples: (1) the keto-alcohol from lauric acid is reduced by hydrogen in presence of a platinum oxide catalyst yielding sym. diundecyl ethylene glycol; (2) the ketoalcohol from methyl laurate is reduced with sodium in amyl alcohol; (3) the keto-alcohol from lauric acid is dissolved in alcohol and reduced by hydrogen and nickel, yielding a mixture of meso and racemic glycols which may be separated by refluxing with acetic anhydride and sodium acetate; (4) the ketoalcohol from lauric acid is reduced in hexahydroxylene with hydrogen and nickel; (5) the keto alcohol from methyl myristate is reduced in hexahydroxylene with hydrogen and nickel; (6) the keto-alcohol from stearic acid is reduced in alcohol with hydrogen and niekel, and racemic sym. diheptadecyl ethylene glycol is separated from its isomer by fractional crystallization; (7) mixed keto-alcohols from methyl laurate and myristate are reduced with hydrogen and nickel. Specification 410,148 also is referred to.

Title: Improvements in or relating to time-division multiplex telecommunications exchange systems
IPC: H04Q11/04
Filed: 1964-04-29
Abstract: 1,056,112. Automatic exchange systems. SIEMENS & HALSKE A.G. April 29, 1964 [April 29, 1963], No. 17764/64. Heading H4K. In a time division multiplex exchange utilizing the resonant transfer method of signalling, each sub-station is connectible to two highways which are themselves connected in series by an inductor. In the system shown in Fig. 2 the highways Mab and Man are respectively used for outgoing (calling) and incoming (called) signals only. Thus a connection between called T1 and called party T2 is made during a single time slot by simultaneously closing switches Sa1 and Sb2 whereby a twoway exchange of energy between capacitors C1 and C2 via inductor L takes place. In. Fig. 3 the highways Ms and Me act as GO and Return highways respectively. In this case transmit capacitor Cal is connected to receive capacitor Cb2 during a first time slot P1 and transmit capacitor Ca2 is connected to receive capacitor Cb1 during a later time slot P2. Consequently transmission takes place through inductor L in only one direction so that a unidirectional amplifier V may be included in the circuit. An impulse (digit) receiver or an incoming exchange line may be connectible uniquely to an incoming (or Return) highway and a ringing generator or outgoing exchange line may be connectible uniquely to an outgoing (or (GO) highway (Figs. 4 and 5. not shown). Subscribers connected to one pair of highways in one exchange may be connected to subscribers connected to another pair in another exchange via a co-ordinate switch K and links CL (Fig. 6). To connect calling station A11 to station A21 for example, the switches Sa11, xl, x3, Sb21 are pulsed simultaneously to effect two-way exchange of energy via inductor L2. If the highways are of the Go and Return type, the switches Sa21, x4, x2 and Sb11 must also be simultaneously pulsed during a second time slot. The pairs of highways may be interconnected by means of a single two-way junction CL5. An inductive parametric amplifier (Fig. 7, not shown) may be used instead of, or in addition to, the inductor L in order to compensate for the various line attenuations of the different subscribers.

Title: An improved lubricating grease composition
Filed: 1942-12-16
Abstract: 576,470. Lubricating greases. STANDARD OIL DEVELOPMENT CO. Dec. 16, 1942, No. 17875. Convention date, Dec. 17, 1941. Drawings to Specification. [Class 91] A lubricating grease composition comprises a mixture of a viscous mineral oil, an aluminium soap of a saturated fatty acid of 10 to 20 carbon atoms, and a small proportion of a phenolic compound comprising a monocyclic or polycyclic mono- or di-hydric phenol or an alkylated amino, halogenated or sulphonated derivative thereof. In its preparation, the mixture heated to about 280-300F. is rapidly cooled to about 90F. and then allowed to stand. The oil is preferably derived from a naphthene base crude and of a viscosity of 50 to 200 S.S.U. at 210F. Aluminium stearate is specified. The phenolic compounds may be naturally occurring compounds. General compounds specified comprise cresols, dihydric phenols, amino-phenols, amyl phenols, halogenated and sulphonated derivatives; particular compounds specified are alpha- and #- naphthol and di-isobutyl phenol. The soap is in the proportion of 3 to 20 per cent. by weight of the oil and the phenolic compound in the proportion of 5 to 30 per cent. by weight of the soap present. Other additions may include free unsaturated fatty acids of 10 to 12 carbon atoms and naphthenic acids as well as their aluminium soaps, and thickening agents such as latex or polybutene. In one method of preparation, the mixture is heated in the usual type kettle provided with an agitator having scrapers working on its inner surface and then cooled by passing through a jacketed helical screw conveyor type cooler. In batch operation the mass is re-cycled to the kettle and allowed to cool therein below the transition temperature, without using the agitator, in continuous operation lower temperature is used in the cooler. In a second method of preparation, the ingredients are passed through an orifice mixer and then through a coil heater. The mass is then allowed to stand to permit separation of occluded gases before passing through the cooler.

Abstract: 565,595. Coating fabrics ; compound sheet materials. UNITED STATES RUBBER CO. Dec. 17, 1942, No. 17926. Convention date, Jan. 3, 1942. [Class 140] [Also in Group V] A foraminous rubber network or coating is formed by directing plurality of laterally spaced continuous streams of rubber-containing liquid upon a travelling backing, moving the streams to and fro transversely to the movement of the backing with such an amplitude as to cause the paths of adjoining streams to contact at their turning points, and converting the rubber-containing liquid to rubber. A fabric 10 drawn from a roll 11 over a roller 12 is coated while passing over a support 13 with latex or rubber solution discharged in continuous streams from nozzles 22 mounted in two rows in staggered relationship in a slide 23 carried by stationary guides 24 and oscillated by a cam and lever mechanism in synchronism with the movement of the fabric, the track of each nozzle on the fabric being a zig-zag line, contacting adjacent tracks at their turning points. The latex is dried and vulcanised by hot air introduced at 46 into a heating chamber 45. Alternatively, a single transverse row of nozzles may be caused to oscillate with a circular motion so that the track of each nozzle on the fabric is a curved looped line. The rubber network may adhere to the fabric, which, if it is stretchable, or if it is condensed as described in U.S.A. Specifications 2,219,829 and 2,233,274, is rendered elastic. The network may be removed from the backing and, if desired, adhered to a fabric or used to unite two fabrics together. Synthetic rubber may be used and the latex may be artificially prepared.
