Title: Improvements in or relating to time-division signal connecting and branching systems
IPC: H04J3/08
Filed: 1966-04-20
Abstract: 1,149,072. Multiplex pulse signalling. FUJITSU Ltd. 20 April, 1966 [20 April, 1965], No. 17380/66. Heading H4L. In an arrangement for inserting relatively low speed signals in vacant time slots and dropping off low speed signals in a time division multiplex system, means are provided for comparing the timing of the pulses of the t.d.m. signal and that of the pulses to be inserted and generating a control signal for controlling the timing of the pulses to be inserted. The system is described in relation to P.C.M. signals but is stated to be suitable for time division signals in general. Signals passing from C, conductor 3, to B, terminal 4, are to be inserted in vacant time slots in t.d.m. signals passing from A, terminal 2, to B, terminal 4, these vacant slots occurring at a frequency equal to the repetition frequency of the signals to be inserted, and signals from B, terminal 5 to C, conductor 7, are to be extracted from the t.d.m. signals passing from B, terminal 5, to A, terminal 6. A timing circuit 16 provides a pulse at 17 on the occurence of a vacant time slot which is compared in phase detector 9 with the signal appearing on conductor 3 to generate a control signal on conductor 10 which indicates the difference in timing between the two signals, the control signal being positive or negative according to whether the error is in the forward or backward direction. The signals to be dropped off are selected by a timing circuit 18 and supplied via an AND gate 19A to a pulse shaper 20, and transmitted via an OR gate 22B to the decoder at the receiver terminal 14. The output of shaper 20 also controls a timing circuit 21 operating at the frame repetition frequency of the low speed signals whose output is supplied to gate the output of phase detector 9 via an AND gate 22A and OR gate 22B to a timing circuit 23. By this means a control pulse is inserted at the end of a frame of the received low speed signals, Fig. 4 (not shown), and is supplied via conductor 15 to a phase control circuit 25, 26 at transmitter 13 which controls the pulse timing of the signals applied at 3 and supplied to conductor 4 via AND gate 8A and OR gate 8B.

Title: Improvements in and relating to processes and materials for finishing surfaces
IPC: B05D5/08
Filed: 1938-06-14
Abstract: 515,896. Coating wood surfaces ; vinyl polymerization products. RENFREW, A., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 14, 1938, No. 17721. [Class 95] [Also in Group IV] A process for finishing wood surfaces comprises applying to the surface an aqueous emulsion of a thermoplastic synthetic resin containing a polymer or interpolymer of a substance containing the CH2= C < group, removing the water and thereby depositing the resin on the surface, pressing the resin deposit at a temperature above the point of fusion of the resin, and finally cooling down while pressure is maintained. Specified synthetic resins are the polymerized esters of methacrylic acid and polystyrene, and the emulsions may be thickened bv the addition of sodium alginate, water-soluble cellulose derivatives or sodium polymethacrylatemethyl methacrylate interpolymers. Fillers and colouring material may be added. The resin emulsion used should be one which, on evaporation of the water at a temperature below the fusion point of the resin, deposits the resin in the form of a discontinuous coating, and it may be applied, e.g. by brushing, spraying or dipping. The pressing stage may be effected by means of polished plates, hot rolls, or other known means. According to examples: (1) Methyl methacrylate,' water, dibutyl phthalate and ammonium persulphate were heated together under reflux and cooled to. room temperature. The emulsion produced was brushed on to 3-ply wood, which was then heated at 60‹C. for 30 minutes, coated again, and dried again. The treated wood was pressed between polished metal plates for 5 minutes at 130 ‹C. and a pressure of 50 lbs. per sq: in. After cooling under pressure to 40‹C., the wood was removed. (2) Styrene, water, ammonium persulphate and caustic soda were heated together under reflux for one hour and cooled to room temperature. A wood veneer was dipped in the emulsion so formed, heated at 50‹C. for 15 minutes to remove water, and pressed between polished metal plates at 110‹C. for 10 minutes at a pressure of 50 1bs. per sq. in. The pressure was maintained while the temperature was allowed to fall to. 20‹C. High gloss finishes were imparted to both sides of the veneer. According to the Provisional Specification, the process is not limited to the use of a polymerized vinyl compound as the thermoplastic synthetic resin.

Title: An improved process for the purification of naphthalene
IPC: C07C7/14
Filed: 1951-07-27
Abstract: In a process for the purification of naphthalene which has been obtained from a molten, naphthalene-rich tar fraction by direct cooling with cold water the naphthalene is washed with hot water whose temperature is in the neighbourhood of the melting-point of the naphthalene or higher, the damp naphthalene subsequently being dried. In a modified process naphthalene, which has been obtained from a molten, naphthalene-rich tar fraction by direct cooling with water, is treated in a centrifuge first with hot water as set forth above, next with an organic solvent, preferably an aromatic hydrocarbon, and then with hot water to wash out the solvent.  The first process may take place in a centrifuge and the hot water may be provided by leading steam into the centrifuge.  The damp naphthalene may be dried by melting and treating with a dehydrating material, preferably concentrated soda lye.  In examples: an aqueous suspension of crude crystalline naphthalene obtained as described in Specification 732,652 by the direct cooling with cold water of a hot liquid naphthalene fraction obtained by distilling coal tar is led into a straining centrifuge and after the aqueous medium has been strained away the residual naphthalene is washed with water at about its melting-point and is melted and dried by the addition of concentrated soda lye (1); in a similar process the hot water washing is followed by rinsing with benzole and a further wash with hot water.  U.S.A. Specification 2,078,963 is referred to.
