Title: Telegraph message transmission system
IPC: H04L12/52
Filed: 1974-06-13
Abstract: 1470859 Telegraphic exchanges INTERNATIONAL STANDARD ELECTRIC CORP 13 June 1974 [20 June 1973] 26275/74 Heading H4P In a telegraph message transmission system including a central processing unit BP, a line block BL receives telegraph characters and sends them over lines 1 g. and a memory unit MEM includes a transmission waiting queue memory FAE into which the line block BL stores the identities NL of the lines for each of which at least one character is to be sent, a transmission memory MLT with one location per line and arranged to receive at least one character CAR to be sent over its associated line, a first buffer memory MT0 arranged to receive a number of characters to be sent over a given one of the lines and a second buffer memory MT1 arranged to receive characters to be sent after those in the first memory. The system also includes a character block unit BC including circuits (CAM, Fig. 2, not shown) for reading from the waiting queue memory FAE the identity of one of the lines served, reading from the line memory cell ML assigned to that line a first indication AD which identifies the first buffer memory MT0 and a second indication which identifies the second buffer memory MT1 and further reading from a buffer memory MT the character to be sent and writing that character into the location of the transmission memory MLT assigned to the line over which it is to be sent. Each cell of the line memory ML contains the address of one character to be sent and a sequence indication marking the transmission phase of the message in progress. A translator TR receives a character to be sent simultaneously with the sequence indication from the line memory cell and supplies in response a new sequence indication PH<SP>1</SP> for replacing the preceding one. The first indication includes in addition to the identity of the first buffer memory MT0 the number of characters still to be sent over the line from those stored in the first buffer memory MT0. A circuit-1 in the character block BC reduces this number at each character transfer from the buffer MT0 to the appropriate transmission memory location MLT. When the buffer memory MT0 is empty the character block unit is caused to commence transferring characters from the second buffer memory identified by the second indication. More detailed operation of the circuits of the system are described Figs. 2-11 (not shown). The memory MEM which may be a ferrite core memory also includes a signalling writing queue memory FAS. As described the character block BC includes a group of memory access circuits (CAM) including a register (A) and a memory register (M), four auxiliary registers (W, X, Y, Z) used to store temporarily information read out of memory MEM by the character block which after a specific processing, rewrites them in the memory MEM, the translator TR (TRS) and a control logic circuit (CLC) including a time distributer (DT) providing clock pulses (t 1 -t 5 ) and a sequence unit formed of a chain of bi-stables. Specifications 1,278,141 and 1,450,428 are referred to.

Abstract: 807,988. Electromagnetic switches. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Aug. 22, 1957 [Aug. 22, 1956], No. 26542/57. Class 38 (5). [Also in Group XXXVIII] A relay controlling a plurality of circuits and comprising fixed electromagnets of like polarity spaced round a circular path and a permanent magnet rotor mounted at the centre of the circular path for rotation by selective energization of just one of the electromagnets, has means operatively associated with the permanent magnet rotor for controlling a circuit in each rotary position. As described for controlling three circuits I, II, III one of the switches 1, 2, 3, for example the switch 1 is temporarily closed to energize the winding 16 of the electromagnet 10 which pulls the permanent magnet rotor 14 to the position shown in solid lines. Simultaneously a cam disc 25 attached to the magnet causes a control rod 27 to be shifted from the contact pair 21 to the contact pair 30 thereby opening the energizing circuit of the electromagnet 10 and completing the circuit I. The magnet remains in this position by virtue of its magnetism thereby keeping the circuit I closed until subsequent closure of a switch 2 or 3 causes further action to take place with resulting closure of circuit II or circuit III.

Patent GB-909056-A (GB)
Title: Process for the manufacture of trimethyl phosphate
IPC: C07F9/11
Filed: 1960-08-04
Abstract: A process for the manufacture of trimethyl phosphate comprises establishing a reaction zone containing from 3 to 20 stages, and continuously feeding methanol, phosphorus oxychloride and an inert gas to said zone, the methanol being fed in at least 30% excess based on stoichiometry.  The inert gas may be an alkyl chloride, specifically methyl or ethyl chloride, or ethylene. From 2 to 10 moles of inert gas may be used per mole of HCl byproduct.  In addition to the inert gas it is preferred to add a sufficient quantity of alkyl chloride in the liquid phase to remove by vaporization the heat of reaction and the heat of solution of the HCl in the reaction mixture, e.g. by installing a reflux condenser above the reaction zone.  Temperatures of 0-50 DEG C. and pressures of atmospheric to 100 psig or higher are mentioned. In examples a 5 plate column is used as reaction zone, the methanol, POCl3 and liquid methyl chloride (when used) being fed on the top plate and the inert gas on the bottom plate.  The process for making trimethyl phosphate may be combined with processes for making methyl or ethyl chloride by reacting the byproduct HCl without separation of alkyl halide with methanol or ethylene respectively in the presence of a Friedel-Crafts catalyst.

Nov. 6, 1950 [Nov. 14, 1949], No. 27041/50: Class 81(2) A gum facing comprises a strip of synthetic resin which is vari-coloured on one surface to simulate natural gum tissues. The gum facing 7 is preferably made of flexible material such as that known under the Registered Trade Mark "Vinylite," or methyl methacrylate in an incompletely cured condition. Two identical sets of facings are manufactured, one set being uncoloured and used to prepare a denture mould and the other set coloured and shaded to represent the natural colour of the gums being used in the completed denture. In preparing a denture, a pattern is formed by applying wax 5 to all but the gum-portion 6 of a cast 2 of the patient's mouth, the cast 2 being made of hydro-cal or gypsum-containing plaster. Teeth 3 are embedded in the wax, uncoloured gum facings 7 being applied to the gum-portion 6 of cast 2, the flexible nature of the gum facing 7 allowing it to be worked to correspond with the teeth 3. Building up strips 12 of synthetic resin are applied beneath the gum-facings 7. A mould is then cast from the pattern, the wax 5 and building up strips 12 are then removed from the mould and the uncoloured gumfacings 7 are replaced by similarly shaped coloured gum-facings 18. The mouth cast 2 is replaced to complete the mould and the space 17 in the mould is filled with synthetic resin of the same kind as that forming the coloured gum-facings 18. The mould and its contents are then subjected to a curing treatment to complete the denture.
