Title: Voltage control for high voltage power transformers
Inventor: HISCOCK NICHOLAS JOHN
IPC: G05F1/14
Filed: 1986-05-03
Abstract: In a system in which a plurality of power transformers supply a common load busbar and each transformer has a respective tap- charging voltage regulator, control signals for the regulators are derived by a circuit in which currents representing the power transformer load currents pass through interposing transformers T1 to be summed by a buswire B, the summed current then passing through interposing transformers T2 via link X, Y and buswire A. The voltage produced across each line drop compensation resistor LDC is proportional to the total load regardless of the number of power transformers in service and does not contain components of circulating current, Any circulating current component present in transformer T1 affects the phase and amplitude of the voltage produced by inductors, INDUCTANCE, in the regulator circuits, each inductor being connected in such a way that this voltage offsets the tendency for the regulator to initiate a tap change which would increase the circulating current. The illustrated circuit is used where the regulator circuit has a norminal 30 (or 210) degree relation between voltage and current, modifications for use where a nominal 90 (or 270) degree relation exists include provision of a variable inductor as the LDC element. <IMAGE>

Title: Suspension units for trailers
Inventor: HARDING KEITH
IPC: B60G7/04
Filed: 1986-12-09
Abstract: Trailers with close coupled axles and torsion bar springing are known in which each wheel is independently sprung. As there is no load equalisation between axles each has to be capable of reacting the full load. A "walking beam" type construction provides equalisation but is heavy due to the substantial beams and the shock absorber required for each wheel. A trailer suspension unit has a beam 5 with stub axle 6 at one end for a wheel 8. A joggled arm 22 has a wheel mounting portion 23 with stub axle 24 for a wheel 42. A torsion bar spring assembly is pivotally mounted in spherical bearings between brackets 2 depending from trailer chassis 1. The outer end of the torsion bar is connected to beam 5 intermediate its ends and the inner end is connected to mounting portion 26 of arm 22. Shock absorber 39 acts between beam 5 and arm 22. Movement limit stops are provided at 21, 46, 47. <IMAGE>

Patent GB-887463-A (GB)
IPC: F16H3/08
Abstract: 887,463. Change-speed gear. ALBION ENGINEERING CO. Ltd., and HILL, W. H. Jan. 20, 1958 [May 4, 1957], No. 14290/57. Class 80 (2). A change-speed gear comprises a hub 12, Fig. 1, splined for axial movement upon a sleeve 5 and forming three gears 13 ... 15 constantly meshing three independently-rotatable gears 16 ... 18 together slidable axially along a countershaft 3 so that radial dogs 2a thereon can selectively engage between lands 16a ... 18a within the bores of the gears which are accordingly selectively clutched to the countershaft to transmit drive. In the form shown, a driving-shaft 2 rotatably supports the sleeve 5 and carries at its end a gear 11 meshing a gear 10 fast on the countershaft 3. At the other end of the countershaft, a gear 8 meshes through a reversing idler 9 with a gear 7 rotatable upon the sleeve 5, fast with which is an output sprocket 6. The hub 12 and the multiple pinion assembly 16 ... 18 are slidden axially of the shaft by plates 19, 20 engaging grooves 12a, 16b; 12b, 18b therein and connected at each side by blocks 21, Fig. 3, having trunnion-pins 22 engaged by the forked ends of a U-shaped lever 23 supported on pivot pins 24 in the gear case 1. An arm 23a, Fig. 4, fast with the U-shaped lever 23, has ball-and-socket engagement with an arm 25 operated by a ratio shift lever 26. On moving the hub and gear assembly 12, 16 ... 18 left or right from the position shown, the radial dogs 2a on the countershaft 3 engage with the lands 16a or 18a in the bores of the gears to either side of the gear 17, to give a ratio change. If the hub and gear assembly 12 &c. is slidden to the extreme right-hand position in Fig. 1, dogs 12c on the hub 12 engage dogs 11a on the gear 11 to clutch the sleeve 5 fast to the driving- shaft 2 for direct drive. If the hub 12 and the multiple pinion assembly 16 ... 18 is slidden to the extreme left-hand position in Fig. 1, dogs 12b on the hub 12 engage dogs 7a on the pinion 7 rotating freely on the sleeve 5, drive now passing from the countershaft 3 through the reverse idler 9 to the gear 7 and hub 12 to rotate the output sleeve 5 backwards. The spacing between the sets of lands 16a ... 18a within the multiple pinion assembly is such that the radial dogs 2a on the countershaft 3 are completely disengaged from both adjacent sets of lands during a ratio shift, the gearing then being in neutral. A resilient detent 28, Fig. 4, cooperates with a notched arm 27 fast on the U-shaped lever 23 to retain the hub 12 and multiple pinion assembly 16 ... 18 in any of the ratio established or neutral positions. As a modification, the gears 7, 8 can mesh directly, the reverse idler 9 being omitted, and an extra forward ratio thereby being obtained. Alternatively, by inserting a reverse idler between the gears 10, 11 and omitting the reversing idler 9 between the gears 7, 8, one forward and four reverse ratios are obtained. By varying the numbers of pinions &c. in the hub and pinion assembly 12 &c., a greater or lesser number of ratios can be obtained.

Title: Laser plasma coating
Inventor: KINKELIN KONRAD
IPC: C23C4/12
Filed: 1990-10-16
Abstract: In laser plasma coating, the feeding of the material to be applied is unsatisfactory. Too much material is blown away and not used for the coating. Moreover, the application is inhomogenoous, depending upon the direction in which the laser beam is moved. According to the invention, as illustrated in Fig 1, the material is introduced directly into the laser beam at an angle thereto which is directed through a head which is arranged around the geometric longitudinal axis along which the laser beam radiates, and has an entrance region and an exit region for the laser. The head has a central interior space arranged around the geometric longitudinal axis and in the exit region the interior space has a coaxial aperture which is slightly larger than the diameter of the laser beam. In use the laser beam is focussed at a focal spot which is traversed by the geometric longitudinal axis and in the region of which a material to be processed can be arranged. The angular momentum is then braked at the latest at the position where the powder leaves the feed head. The substrate may be aluminium, ceramic, glass, stone, plastics or wood and the coating material may be plastics, ceramic or metal. The coated product finds application as an artificial joint, a printing plate or a printed circuit board. <IMAGE>
Patent GB-2242027-A (GB)
Title: Electronic compass
Inventor: SATO HIROSHI
IPC: G04B47/06
Filed: 1991-02-28
Abstract: An electronic compass can store azimuth data relevant to points (A, B, C, figure 7) to be passed by a user in a plurality of registers, and the stored azimuth data are sequentially displayed on a display device every time an external operation switch S4 is operated. The compass includes a magnetic sensor for detecting a geomagnetism, thereby obtaining north azimuth data on the earth. The north azimuth data obtained by the magnetic sensor is displayed simultaneously with the stored azimuth data. Therefore, the user can know at each point a direction to go on the basis of the two displayed azimuth data, i.e. the stored azimuth data, and the north azimuth data on the earth. The arrow 7b on wristband 7 indicates the desired direction when the compass is rotated to bring a "north" indicating dot 4a into line with an arrow display 4b generated by a stored azimuth datum. <IMAGE>
