Title: Improvements in and relating to the manufacture of cermets with metal members bondedthereto
Inventor: ARTHUR GEORGE
IPC: G21C21/06
Filed: 1961-05-01
Abstract: A body comprising a cermet core with an enclosing metal container bonded thereto is formed by pressing mixed ceramic and metal powders into a compacted mass, coating the surface of the mass with metal powder and an adhesive liquid, sintering the coated mass, inserting the mass in a metal container, and hot swaging the assembly at a temperature of 700  DEG C. or above so as to bond the container to the sintered mass.  A cylindrical nuclear fuel element is made by enclosing a mixture of approximately equal volume of UO2 and stainless steel powders in a sealed rubber bag, inserting in an apertured copper sleeve, immersing in oil and compressing by means of a plunger to about 20 tons per sq. inch; the compacted mass is dipped in a suspension of stainless steel powder in polybutylmethacrylate or epoxy resin, dried, and pressed again as previously.  The mass is then sintered at 1350  DEG C. in dry hydrogen and placed in a stainless steel container which is evacuated and sealed.  The assembly is hot swaged in hydrogen at 1000-1200  DEG C. between rotatable dies which have concavities in their opposed faces and are moved towards one another at intervals to hammer the assembly; the hot swaging is repeated with smaller dies.  Reference is also made to coating the mass by dipping in the adhesive liquid and rolling in metal powder, sintering in carbon monoxide, using nickel as the bonding metal, and compacting by gas pressure instead of liquid pressure.

Title: Improvements relating to the manufacture of pipes and the like from sheet metal
IPC: B21C37/08
Filed: 1934-05-28
Abstract: 426,848. Making pipes. HUME, W. R., and HUME STEEL, Ltd., Kinnear House, Melbourne, Australia. May 28, 1934, No. 15903. [Classes 83 (ii) and 83 (iv)] Angular bending ; uniting by fusion.-Longitudinally welded pipes are made by bending a long flat plate by a series of rolls progressively from end to end from its longitudinal edges towards its longitudinal centre without subjecting the plate to pressure at or across the centre line so that the central portion, of generally isosceles triangular shape, remains in a flat state until the leading-end is adjacent the final series of rolls, the radii of all the bends being the same as the radius of the pipe. The plate is fed through a series of six pairs of of rolls 6, 3 of similar form at each edge of the plate but successively nearer to the centre of the plate so that the flat portion is substantially of isosceles triangular form, and the plate is subsequently passed through two further pairs of rolls 3a, 3b co-operating with internal rolls 6<a>, 6b to complete the pipe which is welded by an arc electrode 27. The rolls are mounted on supports adjustable transversely or mounted on swinging or otherwise adjustable longitudinal beams. The rolls 3, 3a, 3<b>, are carried by vertical axes and are driven from the shaft 11 by spur gear 12, bevel gear 14, and worm gear 16, 17, the rolls and worm wheels having bosses 19, Fig. 5, pegged together. The rolls 6 on the first two shafts 7 may be idle or driven from the rolls 3 by bevel gear 5, and the remainder are idle. The rolls 6 of the fifth set are mounted on an inclined shaft 7<a>, Fig. 7, The rolls 6a of the sixth set are mounted on a shaft 22 supported by a hanger 23 depending from a frame 24 and the rolls 6b of the last set are similarly mounted on inclined shafts. The passage formed by the rolls 3a is of slightly greater diameter horizontally than vertically so that the pipe is slightly elliptical at this point, the resiliency of the metal causing it to assume a cylindrical form when it leaves these rolls. The centre of the plate is supported throughout the machine by a bearer 10. In order to effect welding, the seam is supported by a copper backing member 26 controlled by a spring 29 carried by the upper bar 30 of a pair of bars 30, 31, which are secured together at one end 32 and to the hanger 23 at the other end. The front of the member may have an antiwearing piece such as a steel nose 33 and may be provided on its under surface with grooves co-operating with grooves in a separate base 34 for the circulation of cooling fluid. A gasket extends between the edges of these parts. The last two pairs of rolls and the welding mechanism may be carried by a separate unit. In order to prevent bowing of the pipe due to contraction of the weld, the bed of the machine may be curved or the series of rolls may be arranged at slightly lower levels successively so that the plate is fed at a slight downward inclination.

Title: Improvements in or relating to method and apparatus for synchronizing transducer head scanning motion in sound recording and reproducing machines
IPC: G11B5/004
Filed: 1955-06-08
Abstract: 783,865. Magnetic and optical sound reproducing apparatus. DICTAPHONE CORPORATION. June 8, 1955 [June 18, 1954], No. 16444/55. Class 40 (2). A method of synchronizing the scanning operation of a sound recording and reproducing apparatus with the motion of a grooveless type record, comprises advancing the scanning mechanism at a first rate during a first portion of a predetermined amount of motion of the record, and automatically changing to a second rate during the remaining amount of said motion, after which the scan is triggered to the first rate of scan. The method is applicable to magnetic or optical record discs and belts and effects correction of tracking error of the transducer caused by slipping and creeping of the record. In the first embodiment, a magnetic transducer 28 traverses a record belt 10 by means of a lead screw 32 coupled through a friction clutch 46 to driving gear 38. After the transducer has been traversed by one revolution of gear 38, corresponding to an amount somewhat less than a predetermined amount of motion of the record belt 10, a detent 56, forming part of a spring-loaded armature of a relay 30, locks the lead screw 32 against the action of friction clutch 46 until such time that an electrically conducting strip 76 on the record, corresponding to the predetermined amount of motion of the record, reaches stationary contacts 78 which causes a thyratron circuit to be fired to operate the relay 80 and restore drive of the lead screw 32. Fig. 7 shows a record trace 75 on the belt 10, the points B representing a fixed transverse line from which position the drive to the lead screw is restored, and points A representing positions at which the traverse of the transducer is stopped, the longitudinal locations of which vary in accordance with the amount of slip of the record occurring during the last predetermined period. A second embodiment is described in which the lead screw and transducer is stationary and feed of the transducer only occurs during the variable catch-up period, producing a track as illustrated in Fig. 8. Specification 783,866 is referred to.

June 2, 1934, No. 16505. [Class 40 (v)] In order to reduce interference due tc curvature of char acteristic of a homo dyne rectifier the time of traversal of the curved portior is reduced (1) by employing a synchronized pulse gen erator in place of the usual homodyne oscillator (2) by giving the oscillator output a square-topped wave-form (3) by arranging that only the tips of the local oscillations are utilized. An embodiment of method (1) is shown in Fig. 4, and comprises a cross-coupled multi-vibrator 18, 19 triggered by an oscillator 20 and feeding into a homodyne diode rectifier 14 biassed back by battery 21. Method (2) may be carried out by inserting a limiter stage between the oscillator and the detector, Fig. 2 (not shown). Fig. 3 shows an embodiment of method (3) in which the homodyne diode 14, tuned circuit 3 and output resistance-condenser combination 15, 16 form a series loop circuit, the time constant of 15, 16 being large compared with that of the oscillator 11 and small compared with the highest audio frequency dealt with. High negative voltage across resistance 15 due to the oscillator input results in only the tips of the oscillations passing to the filter 9.
