Title: Apparatus for electrolytically treating a metal workpiece
Inventor: BARKMAN ERIK F
IPC: C25D17/00
Filed: 1967-12-14
Abstract: 1,212,873. Electrolytic apparatus. REYNOLDS METALS CO. Dec. 14, 1967 [March 14, 1967], No. 56930/67. Heading C7B. A head 10, containing cathode plates 34, 36 is used in anodizing a surface 40. Electrolyte is passed as indicated by arrows from a manifold 23, and then between the workpiece 40 and cathode plates, to a manifold 30. Contact members 46 confine the electrolyte on the workpiece surface. Any electrolyte which escapes is recovered by a vacuum recovery system including passageways 50 around the outside of the contact members 46. The head is mounted on wheels (54) Figs. 1, 3 and 4 (not shown). The cathode plates 34, 36 are of Pb backed with Cu. The current density on both plates may be the same and may be increased on plate 34 after initial formation of an oxide layer on the workpiece. Specified anodizing conditions for an aluminous metal surface are a H2SO4 electrolyte with a concentration of at least 17% and at 20-40C; a current density of 15-2000 amps/ sq ft and higher; an electrolyte flow rate across the treated surface of at least 50ft/ min. and a voltage of 14 to 50 volts. The head may be used on vertical or horizontal surfaces (the surface either facing up or down). The head may be moved and the workpiece be kept stationary or vice versa. The relative movement between the head and workpiece may be countercurrent to the electrolyte flow. Metal sheets or coilable strips may be passed across the open side of the head. The reverse side of an Al sheet may be cooled by flowing water across it. Prior to anodizing, a sheet may be electro-polished using 50-60% H2SO4, at 40-50C. and a current density of 2-600 amps/sq. ft. Additionally or alternatively, it may be etched in a NaOH or Na2 CO, etchant smutting resulting from the electro-polishing or etching may be removed electrolytically using 26% H2SO4 solution at 15 volts. Following the anodizing, the sheet may be desmutted, rased and sealed. Sealing may be by employing hot water, steam or a phosphate-chromate solution, e.g. one comprising H3PO4, AlF3, K2Cr2O7 and HCl.

Title: Improvements in or relating to humidity measurement
Inventor: GRONINGER KURD
IPC: G01N27/12
Filed: 1967-12-21
Abstract: 1,205,259. Measuring humidity electrically. SINA. A.G. Dec.21, 1967 No.58189/67. Heading G1N. A moisture sensitive transducer 23, Figs.2, 3 comprises: a hollow insulating tube 24 containing a reference resistor 31, a parallel adjacent insulating rod 26, and a hygroscopic moisturedependent resistance in the form of an electrolyte 27 retained in the space between the rod and the tube the latter carrying electrodes 25. The tube may be of quartz glass and the reference resistor may consist of the same electrolyte; a cylindrical perforated or porous metal filter 30 surrounds the tube and rod. The sensing electrolyte 27 is held by capillary action. The relative humidity of a gas, e.g. that in a vacumn drier 11, Fig.1 (not shown) is measured by drawing the gas through a chamber (18) by a pump (15) and controlling by means of a valve (20) the number of gas molecules per unit volume in the chamber 18, the humidity being sensed by the transducer 23. The number of molecules per unit volume is varied, in an alternative embodiment, Fig. 5, (not shown) by opening a valve (52) linking the vacumn drier (11) to a space (118) in a cylinder (41) at one end which a piston (42) is held to give the space (118) its maximum volume, and then closing the valve (52) and releasing the piston (42) so that the gas from the drier is subjected to the pressure admitted through a hole (50) to the space (51) behind the piston. This pressure may be atmospheric, and the transducer (23) again senses humidity. Thus the pressure of a gas whose humidity is to be measured may be raised, or alternatively lowered as in the case of a source of supersaturated steam, so that the resist- or 23 operates in the pressure range corresponding to its maximum sensitivity. In a further embodiment, Fig. 6 (not shown) a chamber (55) recieves a sample of the gas from vacuum drier (11) and contains a bellows (62) or a box (66), Fig. 8 (not shown) sealed with a diaphragm (67), the interior of the box or bellows being at a controlled, or desired humidity and having a second moisture sensing transducer (23). The bellows expand a connection of the chamber (55) to the drier (11) and the pressures equalize. The two resistors are bridge connected, Fig. 7 (not shown) and a conveyor type vacumn drying process may be controlled by the bridge output.

Title: Railway vehicle and railway system incorporating the same
IPC: B61B13/12
Filed: 1972-12-22
Abstract: 1385579 Railway vehicle guide wheels; railway system MESSERSCHMITT - BOLKOW-BLOHM GmbH 22 Dec 1972 [23 Dec 1971] 59413/72 Heading B7L A railway vehicle having supporting wheels 3 and guide wheels 4, also has a left and righthand pair of displaceable guide wheels 9 carried on a support member 10 which is movable about a vertical axis through a pivot pin 12 into either of two end positions to present either guide wheel 9 for engagement with a guide rail (e.g. rail 33 on Fig. 3), and an operating mechanism 13, 14, 15 which can be set to bias the member 10 into a selected one of its end positions from which member 10 may be displaced against the bias into the other end postion without causing resetting of the operating mechanism. This mechanism comprises a lever 13 pivotable about the pin 12, an arm 14 which is slidable in an end piece 21 of the lever 13 and is pivotally connected to the member 10 at a pin 23, and a spring 15 between the pin 23 and the end piece 21. Pin 23 is guided in a slot 24 in the top wall 16 of body 1 housing the mechanism, and side walls 31 of the body 1 act as stops for limiting movement of the lever 13. As shown in Fig. 3, guide rails 33 and 34 are provided at points in a railway system for alternative engagement by the appropriate wheel 9 to guide the vehicle at 32 into the track preselected by setting of the operating mechanism. When a vehicle approaches the points from the opposite side thereof, e.g. at 36, a control rail 37 contacts a wheel 9 and displaces the member 10 so that the other wheel 9 is positioned to engage the relevant guide rail 34 (or 33). This displacement is achieved regardless of the setting of the mechanism 13, 14,15, and this setting may be changed even while approaching or passing through the points if so desired in preparation for subsequent points, since when the vehicle has passed the points, the bias of spring 15 returns the mechanism to the chosen setting. The railway system may be ground based, or it may be of overhead type as shown in Fig. 5, where the wheels 3, 4 and 9 all run within a slotted conduit but additional guide wheels 43 are provided to help support the vehicle during a gap in a support surface 5 at points. The vehicle may be driven by a linear motor having stators fixed to side walls 8 of the conduit.
