Title: Improvements in or relating to heat treatment of steel rod
Inventor: SIMS RAYMOND BERNARD
IPC: C21D9/52
Filed: 1962-12-21
Abstract: A steel rod, particularly for drawing into wire and containing 0.40 to 0.85%C., is heat treated by coiling it leaving a rolling mill e.g. in coilers 12, and immersing it in a fluidized bed 14 e.g. supported on a cradle 23 to cool it below 700 DEG C. Preferably, the coiled rod is immersed in the fluidized bed before it has cooled below the austenitic-ferritic change point (720 DEG C. for 0.70%C. steel) and is cooled to a temperature below the upper limit (650 DEG C. for 0.70%C. steel) of the range within which transformation to a fine pearlitic structure occurs within 4 seconds, the temperature of the rod being maintained within this range e.g. between 650 DEG C. and 550 DEG C. for 10 to 30 seconds.  After removal from the bed e.g. using conveyer 15, the rod may be water cooled in a spray booth.  The bed may be granular material such as sand fluidized by a non-scaling gas such as nitrogen, and cooled by a coolant such as water, CO2, liquid alkali metal or Pb-Bi alloy, circulated around the bed container walls. <PICT:1040760/C6-C7/1>

Title: Improvements in or relating to data processing systems
IPC: H04M3/00
Filed: 1968-10-18
Abstract: 1,205,309. Exchange systems; data transmission. SIEMENS A.G. 18 Oct., 1968 [19 Oct., 1967], No. 49400/68. Headings H4K and H4P. In a data processing system messages to be transmitted are compiled as an arbitrary number of equal-sized words and the number of such words constituting a message is sent prior to sending the message. The specific embodiment relates to a processor controlled telephone exchange and the signalling employed between the processor and a buffer circuit serving a mixed group of individual circuits comprising a switching network. The messages between the processor and a buffer circuit comprise a number of sections each of the same bit length. The first section indicates the total number of sections constituting the message, the second and possibly also the third sections indicate the address of the network equipment to which the message relates, while the succeeding sections to a maximum of a further four comprise control data relative to processor work functions. In transmitting from a buffer to the processor reception of the message length indication is acknowledged by the processor to elicit the next section of the message and so on. Message length is recorded in both buffer and processor to determine the last section sent and received. In transmitting from the processor to a buffer, the processor sends the acknowledgment signal to prepare the buffer before sending each section of a message. Absence of acknowledgment signal or reception of data in illogical order results in fault signals. The exchange system is the same as that described in Specification 1,205,305.

Abstract: 1445888 Cooling electric cables KABELUND LACKDRAHTFABRIKEN GmbH 26 Oct 1973 [27 Oct 1972] 50033/73 Heading F4U [Also in Divisions H1 and H2] In a cable installation a conductor 1 has a longitudinal channel la through which coolant, such as water, may be passed in contact with the conductor. The coolant, at the same potential as the cable conductor, passes through heat exchange and pumping means, 8 and 7 respectively which are insulated from earth by the insulating supports 9, 9a, 9b and the insulating shaft 12. The heat exchanger 8 is provided with a blower 10 which is at earth potential.  Return of the coolant to the pump may be by means of a second length of cable, Fig. 2 (not shown). Alternatively the longitudinal channel may be subdivided as shown in Fig. 3, for example, in which channels 20 provide for the flow and channels 21 for the return of the coolant. Such a cable may have heat exchange and pumping means coupled between flow and return channels at each end of the cable as in Fig. 4 (not shown). In a modification of the above system blower 10 may be driven through insulated shafts or the like or through transformers having windings insulated from one another for high tension use; the pump 7 may also be driven through a transformer. Measuring and control devices which are at high tension, e.g. in the flow path of the coolant, may be connected by radio or optical means to switch gear which is at earth potential.

Abstract: 1,125,319. Edge-connectors for printed circuit boards; knife edge connections to tape cables. UNITED CARR Inc. 7 Dec., 1965 [16 Dec., 1964], No. 51893/65. Heading H2E. In a tape cable connector, electrical contacts mounted in an insulating body each have, at one end, a cutting blade which splits the end portion of a conducting tape of a cable secured in the body so that both sides of the blade make contact with the tape. In one embodiment (Fig. 1) the cable 29 is clamped between two portions 20, 21 of an insulating block so that grooves (63, 64, Fig. 2, not shown) extending through each portion are aligned to form vertical slots 38 each bisected by a cable tape 29. Correct positioning of the cable may be assisted by the use of transparent body portions and cable insulation or by chamfers 66 and 67 and aligned notches (64, 65) on the body portions, and securing of the cable may be assisted by the use of roughened surfaces or co-operating ridges and grooves (Fig. 4, not shown). Contacts 4, each terminating at one end in a blade 7 with a cutting edge 8 and at the other in two springy fingers 10 for engaging a printed circuit panel, are secured in slots in an insulating housing 3 by engagement of shoulders and springy tongues 11 with walls 16. The cable-carrying block 20-21 is guided into a hollow portion of the housing 3, by means of projections 53 and slots 52, so that the blades 7 are snugly received in the slots 38 and split the tapes 29, separation of the block and housing being prevented by engaging projections 48, 49. In a modification (Figs. 5 and 6, not shown) the connector block comprises an L-shaped member (76), having contact-carrying slots, and a further insulating member (77) which clamps the cable to the L-shaped member. Preferably the contact blades are arranged to perpendicularly bisect the ends of the cable tapes but they may enter bent-back tapes at any point to slit them longitudinally. (Fig. 8, not shown).

Abstract: 1383918 Making waveguide couplers MARCONI CO Ltd 5 Oct 1972 [9 Nov 1971] 51906/71 Heading H1W A waveguide multi-aperture coupler is made by coating a mandrel with conductive material to form a first waveguide length, etching apertures in the material and filling the apertures with soluble material, providing a further length of waveguide over the apertures, and, finally, dissolving the material in the apertures. As shown, the first length is of semi-circular section and is formed on a brass mandrel (not shown) covered in oxide to prevent adhesion of a thin coating of copper applied thereto by electrodeposition. The apertures 6 are formed using known photolithographic and etching techniques, after which they are filled with epoxy resin. Electrodeposition is continued to form a block 7 which is then machined to provide a channel 10 communicating with the apertures 6. The mandrel is removed and the material in the apertures dissolved using methylene chloride. A block 11, containing a slot 12 forming the second half of the further waveguide length, is attached by bolts (not shown) to the block 7. A coupling between two semi-circular waveguides may be formed by the same method. In a modified method, the semi-circular waveguide is coupled by two rows of apertures to the broad face of a rectangular waveguide which, like the semi-circular guide, is made by depositing material on a mandrel.
