Filed: 1966-10-07
Abstract: 1,156,634. Electric solid-state devices. J. ROYER and R. CHARBONNIER. 7 Oct., 1966 [7 Oct., 1965], No. 44995/66. Addition to 1,116,659. Heading H1K. The assembly depicted in Fig. 3 of parent Specification 1,116,659, is modified by mounting the thermally sensitive element 72-which carries components (transistors) 78 whose temperature is to be stabilized-on a plate 70 which is separated from the housing base 50 by the pillars 54, 56, &c. which connect the external leads to the internal leads 80, 82, &c. These pillars provide a shunting thermal resistance which is substantially less than the thermal resistance of the components 78 and the thermosensitive element 72. This thermal shunting is in contrast to the arrangement shown in Fig. 3 of the parent Specification, in which the members corresponding to the present pillars are thermally in series with the thermosensitive element and the associated component.

Title: Laser welding method
IPC: B23K26/20
Filed: 1971-09-29
Abstract: 1320640 Welding by fusion COMPAGNIE GENERALE D'ELECTRICITE 29 Sept 1971 [29 Sept 1970] 45338/71 Heading B3R Point or short line welding by continuous laser beam, without beam interruption, is effected by pre-heating with an unfocused portion of the beam, effecting local fusion with the beam focus, and annealing with an unfocused portion of the beam. As shown, a cylindrical beam from a continuous laser, such as gas (e.g. CO 2 ), liquid or solid state, is focused by a lens 10 to provide a cylindrical focus 5. Metal workpieces 1, 2 are successively moved from a position A where they are placed in contact, through a position B in the beam convergent portion to effect the pre-heating, the beam focus C to effect fusion at and around a point 3, and a position D in the beam divergent portion to effect the annealing, to a weld completed position E. At the preheating stage the workpieces may be held stationary or moved towards the fucos at a speed such that the pre-heating is effected before the focus is reached. At the fusion stage, the workpieces may be held stationary or slowly moved along the focus cylinder. The welding may be automated, new workpieces being moved into the position B on completion of annealing, e.g. before the welded workpieces are removed from position D. In alternative embodiments, the workpieces may be moved in reverse direction to that shown; the positions B and D may be on the same side of the focus; and the workpieces may be fixed with the lens being moved or a variable focal length lens used.  The lens 10 may be circular for point welding or cylindrical for short line welding.

Abstract: 1,016,971. Fluid heater cleaners. BAB-  COCK & WILCOX Ltd. Dec. 18, 1962 [Dec. 21, 1961], No. 45779/61. Heading F2N. The nozzle tube 1 is supported by a front support 6 which is fixed to the longitudinal frame 7 and by intermediate and rear supports 10, 8 which are on wheeled carriages. The wheels 12 on the carriage 11 of the intermediate support 10 run between the upper and lower flanges of channels 23, and on the carriage 11 is a casing 13 in which is rotatable a spider carrying form rollers 15 of concave surface in which the nozzle tube 1 can run. The front support 6 is similar except that it has no wheeled carriage. The rear support 8 (see also Fig. 4, not shown), has a carriage 24 with wheels 25, and a casing 26 in which a member 28 is rotatable and carries a ring to which the rear end of the nozzle tube is welded. The member 28 also carries a gland 30 through which a steam feed tube 31 passes. This tube is supplied through a valve 43 and is supported also by a support 33 on a wheeled carriage 34. The carriages are reciprocated by a chain 53, Fig. 5 (not shown), which is driven through a sprocket 46 by a reversible motor 45. This chain runs parallel to the frame 7 and round a rear sprocket 54, one strand being attached to the rear carriage 24. The other return strand of the chain engages a sprocket 61 which is mounted on a vertical shaft in the rear support 8 and which drives the member 28 through bevel gearing 63, 64. The chain strand is kept in contact with the teeth of the sprocket 61 by a plate 68. A keyway 80, Fig. 4, permits 90 degrees of lost motion between the gear 64 and member 28. This strand has a link with an extended side plate 70, Fig. 5, which engages projections 71, 72 from the carriage 34 of the feed tube support 33 and advances the carriage to ensure that too great a length of the feed tube shall not be unsupported. For a similar purpose a link with an extended side plate 75 engages projections 73, 74 from the intermediate carriage 11 on the return movement of the chain. The steam inlet valve 43 is operated/through a connecting rod 87 when a lever 86 is engagedby a roller 85, Fig. 7, on the carriage 24 as it moves forward, the roller carrying the lever 86 over dead-centre so that the valve 43 remains open until, on the return of the carriage 24, the roller 85 engages the other side of the lever 86 and closes the valve. The roller 85 may be positioned in any of holes 83 in an elongated plate 85 in order to adjust the timing of the valve 43.

Title: Method of and circuit arrangement for reducing the dissipation caused by the information currents in a core store
IPC: G11C7/04
Filed: 1969-09-17
Abstract: 1277305 Magnetic storage arrangements LICENTIA PATENT - VERWALTUNGS GmbH 17 Sept 1969 [17 Sept 1968] 45874/69 Heading H3B [Also in Division G4] Power dissipation in a known coincident current n bit word store is reduced by storing any word having at least n/2 "0" bits in an inverted form, a record of inversion being made in an n+ 1th bit. The known store comprises n planes, Fig. 2, one bit of each word being stored per plane, and each plane has an inhibit wire J. The nth plane contains check bits each of which is written as either "0" or "1" to make the number of "1" bits of a respective word, together with its check bit, even. Each word thus comprises n - 1 information bi s and a check bit. Power dissipation in this known store is greater when a "0" is written in a bit than when a "1" is written, because of the use of the inhibit wire, and inversion of information thus may allow lower operating temperatures. According to the invention, the number of "0" bits in the word may be ascertained, Fig. 3, by connecting the inhibit signals JA from the information register to one input of a differential amplifier 31 via equal resistors (not shown) which form a D/A converter 30, the second input of amplifier 31 being from a reference potential U ref  chosen so that the amplifier gives a "1" output for n/2 or more "0" inhibit inputs. This output is stored in an n + 1th plane, and is also gated with the inhibit signals JA, Fig. 4 (not shown), to produce inhibit drives KJA for the planes, inverted as required. The signals stored in the n + 1th plane are used to reinvert the information of the word on readout.

Abstract: 1489519 Making helical seam tubes E SIEGWART 12 Nov 1975 [13 Nov 1974] 46776/75 Headings B3E and B3A Apparatus for forming helical seam tube comprises two seaming rolls 5, 6 at the point of strip entry and a circle of tube guide rolls 9 each freely rotatable on a carrier 8 pivotable about a shaft 12 perpendicular to the plane of the incoming strip. When the coiled strip is plain, each roll 9 may have a flange guiding the first strip convolution, but when as shown the strip 1 is corrugated by roll pairs 2, 3, 4, the rolls 9 have a matching profile. The seaming rolls 5, 6 may form conventional lock seam at adjacent strip edges, or may be as shown in Fig. 3, being mounted on intergeared driven shafts 16, 16<SP>1</SP> on carrier 8. In this case, the convolutions have a pitch equal to half the strip width, and interengaging corrugations are deformed to dovetail shape to connect the overlapped strips as in Specification 1,431,222. To thrust the incoming strip firmly against rollers 9 and to prevent a tendency for the tube diameter to increase, each seaming roll 5, 6, is made in two portions of decreasing diameter in the case of the inner roll 5, going in the direction of tube formation, and increasing diameter, roll 6. Similarly if the coiling pitch is one-third of strip width, the rolls are in three parts. The rolls 9 are adjustable radially of their circle in slots 19, and carrier 8 is adjustable parallel to shaft 12, to vary the diameter of coiling. The seam may alternatively be formed by a bonding agent sprayed on to the incoming strip and/or convolution being formed at the area of overlap.
