Abstract: 796,937. Extruding. SCHLOEMANN AKT.- GES. April 6, 1956 [April 22, 1955], No. 10618/56. Class 83 (4). A horizontal metal rod and tube extrusion press has its billet container 7 supported by bearing plates 15 disposed exclusively above the main axis of the press. The container is mounted in a holder 8 having a downward extension 9 running in a guideway 11, and an upper extension carrying bearings 14 supported on the bearing plates 15. Bearings 14 have semi-cylindrical surfaces 14a to permit selfalignment. Bearing plates 15 are carried by beams 16 mounted on the upper press columns 1, 2 and having a number of cross-braces 18. The beams 16 may be secured at their ends to the pressure cylinder 20 and bolster 21, Fig. 1 (not shown), of the press or they may be supported only by the upper columns. Alternatively the bearing plates 15 may be mounted directly on the upper columns. The bearings 14 or the bearing plates 15 may be adjustable for alignment of the container. Dust protectors 19 are provided for the bearings and cooling water is sprayed from perforated pipes 25.

Title: Bale stacking trailer
IPC: A01D90/08
Filed: 1966-03-11
Abstract: 1,118,892. Bale stacking trailers. W. R. BISHOP, and F. J. BROCCO. 11 March, 1966 [17 March, 1965], No. 10900/66. Heading B5F. Bales 110 from a baler are delivered to a bale stacking trailer having a conveyer chain 58, and a predetermined number of bales are moved one-by-one by an arm 95 pivoted at 97 through an arcuate path to a stack forming station 120; subsequent bales are moved by the conveyer 58 to a bale lifter having forks 177 which elevate the bales in turn so that a plate 186 can move them to form a second layer disposed at right angles to the bales of the first layer. When the stack is complete it is ejected by means of conveyer chains 152 through doors 124 opened by an hydraulic jack 140. The bale shifting arm 95 is operated by an hydraulic jack 102, the bales being restrained by an arcuate wall 112. The lifter forks 177 (shown in their elevated position in Fig. 6) are mounted on parallel pivoted links 170 and are raised by means of an hydraulic jack 180. The pusher plate 186 is operated by an hydraulic cylinder 188. The bale trailer is connected by a pivot shaft 45 to the end of a bale discharge shoot 11 which is provided with a bale turning device 70. This comprises an elongated L-shaped wall the horizontal part 73 of which has an inner edge 75 which does not extend as far as the centre of the shoot 11. The bale is thus dropped on its edge on to the floor 27 of the trailer and is carried rearwardly by the conveyer chain 58 until the bale engages a trip lever 214. Fig. 7 (not shown) shows mechanism operated by the lever 214 for allowing a predetermined number of bales to be moved by the arm 95 to the station 120. The lever 214 is then moved out of the way by a jack (220), Fig. 4 (not shown) and the subsequent bales are moved further rearwardly to engage a second trip lever 230. Fig. 11 (not shown) shows an hydraulic control system for automatic operation of the various hydraulic jacks and motors. Modification.-In Figs. 9, 10 (not shown) lifter forks (370) are elevated by means of an hydraulic motor (382) through a drum (365) and chains (380).

Title: Improvements in or relating to ultra-high frequency amplifiers
IPC: H03F7/02
Filed: 1959-04-01
Abstract: 887,601. Gyromagnetic amplifiers. MARIE, G. R. P. April 1, 1959 [April 17, 1958], No. 11049/59. Class 40 (9). In a gyromagnetic amplifier, a cylindrical sleeve 21 of ferrite material is polarized by a constant magnetic field parallel to its axis and is excited by an alternating magnetic field around the axis, the two fields together producing precession of the elemental magnetic moments. A pumping-wave of frequency #2 from a source 31 is fed via a coaxial cable 32 to a conductor 30 on the axis of the sleeve to provide an alternating current with an associated alternating field. The sleeve is enclosed in a cylindrical cavity 16 which, by means of rods 19, 20, is tuned to resonance at the signal frequency #1 for waves in the TM110 mode. A wave-guide 1 conveying the signals of frequency f1 from right to left in the TE10 mode is coupled to the cavity 16 by a coupling device 5. The signal amplified in cavity 16 is returned to the waveguide and travels in the same direction as before. The coupling comprises two cylindrical cavities 6, 7 tuned by rods 11, 12 and 14, 15 to waves of signal frequency #1 in the TE111 mode. Slots of dumb-bell shape 9, 10 and 171, 172 &c. couple the cavities 6, 7 to the wave-guide 1 and to the cavity 16. The two cavities 6, 7 are coupled by a hole 13. The ferrite sleeve 21 is mounted between a polepiece 22 and a wall 18 of an iron enclosure 23. The enclosure 23 forms a magnetic circuit which is energized by windings 27 controlled by a battery 28 and an adjustable resistor 29. The wall 18 which forms part of the cavity 16 is coated with copper. The signal waves in cavity 16 cause nutation of the magnetic moments precessing in the magnetic field maintained by the bias and pumping sources. The signal and pumping frequencies #1 and #2, and the gyromagnetic resonance frequency fo of the ferrite are of approximately the same frequency. For the best results, 2# 2 =#1+#0. The sleeve 21 may be formed in three or four segments 331 to 334, Fig. 3. Each segment is wound with a few turns of wire which is short-circuited or connected to an impedance to damp the nutation at frequency #2-#1 and to increase the variation in precession. Specification 800,056 is referred to.

Title: Improvements relating to Gas-Turbine Engines for Driving Vehicles

Abstract: 1,162,939. Gas turbine plant. DAIMLERBENZ A.G. March 7, 1968 [March 9, 1967], No.11166/68. Headings F1G and F1T. The invention relates to a gas turbine engine for driving a vehicle, the engine comprising two useful power turbines, one being a starting turbine and the other a normal operation turbine, the normal operation turbine being secured on a shaft, and the starting turbine being connected to the shaft through a freewheel drive. Combustion gases are supplied through a duct and are directed either to the starting turbine or to the normal operation turbine by a valve device. In the embodiment shown, a normal operation turbine 14 is secured on a shaft 12 which is rotatably supported by bearings 16, 17 within a casing, the shaft having a flange 18 for connection to an output shaft. A starting turbine 13 is mounted on the shaft 12 by means of a freewheel device 20. Combustion gases from a gas generator, not shown, pass to a duct 32 which divides into two branches 33, 34, the branch 33 leading to volute 30 from which gases may pass through inlet guide vane assembly 28 to drive the starting turbine 13, and the branch 34 leading to volute 31 from which gases may pass through inlet guide vane assembly 29 to drive the normal operation turbine 14. The gas flow either to branch 33 or to branch 34 is controlled by a flap valve 35 pivotally mounted at 37 and controlled in dependence on speed of the shaft 12 by means of centrifugal device 38 and actuating linkage shown. The arrangement is such that at zero and low speeds of the shaft 12, the valve member 35 is positioned as shown so that gases pass to the starting turbine 13 which has high torque at low speeds, while when the shaft reaches a predetermined speed the device 38 causes the valve member to move to the other position shown by chain line so that the gases now pass to the normal operation turbine 14 which thus takes over the drive, the starting turbine coming to rest. The two turbines discharge into a common outlet chamber 23.

[Classes 57 and 122 (iv).] A fuel-injection pump 5 is controlled by a speed governor 6 through a fluid relay supplied by a pump 8. Should the fluid pressure fail, a piston 23 closes the contacts 24, energising a solenoid 26 to actuate a valve 28 allowing fluid pressure to actuate the piston 31 which, through the agency of the lost motion device 33 and the spring 35, reduces the pump delivery without moving the power piston 20. In a modification the piston rod 18 is hollow and the pump regulating member is secured to a rod formed with a spring loaded piston sliding in a cylinder formed upon the rod 18. The fluid pressure is admitted to the hollow rod and acts against the spring. The piston 23 may act through mechanical, pneumatic, hydraulic, or electrical transmission upon the valve 7.
