Patent GB-1357045-A (GB)
Title: Balancing machines
IPC: G01M1/22
Filed: 1972-02-17
Abstract: 1357045 Balancing machines JACKSON & BRADWELL Ltd 19 Feb 1973 [17 Feb 1972] 7311/72 Heading G1N To remove the dependence of the output signal of a dynamic balancing machine on the rotation rate the signal is multiplied by the inverse of the square of the rotation rate. In the Fig. an imbalance signal is produced by transducer 3 associated with one of the bearings of body 1. A further transducer 4 produces a sinusoidal rotation rate signal which is converted to pulses at 5, integrated at 6 and divided into a standard rate signal (here 50Hz) at 9. The resulting signal is an inverse of the rotation rate and is squared at 10 before being multiplied by the amplified and rectified signal from the imbalance transducer. The rotation rate signal may be derived from transducer 3 instead of 4 but in general transducer 4 is required to produce phase information necessary for positioning a compensating mass on body 1.

Title: Improvements in the manufacture of steel by the bessemer process
IPC: C21C5/28
Filed: 1945-03-23
Abstract: In a process for the manufacture of Bessemer steel the bath depth is decreased compared with normal practice so that a blast of lower pressure may be used, whilst at the same time the tuyene area is increased to avoid lengthening the blast or to shorten it, the normal weight of charge being maintained by increasing the surface area of the bath.  The decrease in bath depth and increase in tuyene area may be not less than 10 per cent and preferably not less than 20 per cent.  The blast may be enriched with oxygen or oxygen-containing gases or, during the latter stages of blowing, materials containing oxygen or oxygen and carbonaceous matter may be added to the bath to give an equivalent of 30 per cent oxygen in the blast.  The process may be operated in conjunction with the processes described in Specifications 493,610 and 518,212 to produce low phosphorus low nitrogen steel.

Filed: 1963-02-26
Abstract: 985,380. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 26, 1963, No. 7591/63. Heading H1K. A four-region three-electrode semiconductor switching device is produced by diffusing impurity into a doped wafer of semi-conductor material to form an inner region of one conductivity type surrounded by a surface layer of opposite conductivity type, fusing a metal disc to one major surface of the wafer to form a rectifying contact and fusing a second metal disc to the other major surface to form an ohmic contact which, together with the underlying surface layer, is then divided by etching a circular groove into the wafer as far as the inner region. As shown, Fig. 4, an N-type silicon wafer is diffused with aluminium, boron or gallium to produce a P-type surface layer 22 surrounding an N-type region 23. A metal disc 21 and a gold-silicon alloy disc 24 are alloyed simultaneously to opposite major faces of the wafer to produce N-type and P+-type regions respectively. As shown, Fig. 5, a circular groove 25 is formed by masking the face of disc 24 with wax, scribing the wax and then etching until the groove extends to region 23. Alternatively the disc 24 can be constructed as a disc 24a and an annulus 24b so that when these are alloyed to the wafer the groove can be etched through region 22 only using the goldsilicon alloy regions as a mask. Ohmic contacts 26, 27 and 28 are then made to regions 21, 24a, and 24b to form the emitter, collector and gate contacts respectively. Heat sinks may be applied to both emitter disc 21 and to collector disc 24a.

Filed: 1965-02-25
Abstract: 1,086,922. Ultrasonic flaw-detection; ultrasonic probes. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. Feb. 25, 1965 [Feb. 28, 1964], No. 8086/65. Headings H4D and H4J. An ultrasonic transducer assembly for inspecting test-pieces having non-parallel opposed surfaces, e.g. railway rails, comprises at least two piezoelectric wafers mounted on a single damping block, the planes of the faces of the wafers being angularly displaced with respect to each other such that the beams of ultrasonic energy emitted by the wafers partially overlap during their entire passage through the testpiece, said wafers being supplied by a single common source of electrical energy. In the embodiment of Fig. 1, two wafers 1 and 2 are energized by a pulse generator 3 and coupled by a medium 6 to the test piece 9. Substantially the whole cross-section of test piece 9 is swept by the resulting broad ultrasonic beam. Echo pulses from the front surface 17 and rear surface 16 of the test piece 9 and from flaws within the test piece are detected by the wafers 1, 2 and displayed on an oscilloscope. Provision may be made for eliminating echo signals other than those of direct reflections of longitudinal mechanical waves from the display. A further recording instrument is used for recording flaw echoes only. The energy of the beam reflected from the rear surface 16 of test-piece 9 provides a measure of the acoustic coupling efficiency and may be used as a reference value to control the ultrasonic energy introduced into the test piece by the wafers 1 and 2.

Title: Improvements in and relating to pneumatic driving hammers
IPC: B21J7/24
Filed: 1954-03-19
Abstract: 739,518. Driving piles. COMPAGNIE INTERNATIONALE DES PIEUX ARMES FRANKIGNOUL SOC. ANON. March 19, 1954 [March 24, 1953], No. 8122/54. Class 68(2). [Also in Group XXII] A pile-driver or the like comprises a striking mass 6 secured to a cylindrical part 7 which includes a cylinder 10 in which air is compressed by a stationary piston 11  when the mass 6 is raised, the mass being raised by a vertically operable rod 24 which has a releasable connection with the mass 6, the release of the mass being effected by the contact of pins 33 with the piston 11. The mass 6 falls on to the bottom member 3 which transmits the blow to the pile on which it rests, the force of the fall being augmented by the expansion of the air in the cylinder 10. The rod 24 may be operated electrically, or may be attached to a powerdriven crank, but as shown in Fig. 1, is actuated by oil admitted under pressure through the pipe 27 and ports 26 to the annular space under the piston 23. The compressed air cylinder 10 is connected by ports 14 to closed compartments 15 arranged around the cylinder and to a single cylinder 17 which co-acts with a stationary piston 20 which contains a non-return valve 22 and is carried by the rod 21 from the cover 2 of the pile-driver. The piston and cylinder 20, 17 form an air pump which discharges past a check valve 18 and port 14 into the cylinder 10. The function of the air pump is to discharge air under pressure, at each stroke into the space 10, 15, the compression ratio in the pump 17 being greater than in the space. This addition of air to the space 10, 15 continues to increase the initial i.e., pre-stroke, pressure in that space until the final compression pressure in the space lifts an adjustable atmospheric vent valve 19. Adjustment of the valve 19 thus determines the extent to which the gravity blow of the mass 6 is augmented by air pressure. The releasable connection between the rod 24 and the mass 6 comprises a head 28 on the rod in which are slidable the spring-raised pins 33. These pins have wedge-ends which, when the pins 33 are depressed by contact with the piston 11, move catches 30 inwardly against spring pressure, and thus withdraw the catches from recesses 35 in the mass 6. When the rod 24 is forced down by fluid pressure from pipe 55, the sloping end faces of the catches engage the sides of the opening in the mass and the catches are forced inwardly to snap into the recesses 35. In a modification, the releasable connection comprises pivoted hook-like members which are pressed by spring-means into lifting engagement with revoluble pins, the hook-members being withdrawn from the pins by the contact of extensions thereon with a stationary abutment. A motor-driven oil pump discharges through a distributor alternately to the pipes 27, 55, the distributor being actuated mechanically by means which are operated at each end of the stroke of the rod 24.
