Title: Stripping electrolytic zinc from aluminium cathodes - using aluminium cathodes provided with a steam-treated oxide coating of high density
Inventor: KAMMEL ROLAND PROF DIPL ING DR
IPC: C25D1/22
Filed: 1975-10-10
Abstract: Electrolytically deposited Zn is stripped from Al cathodes more easily by coating the Al cathodes with an oxide layer which is made denser by treating in a hot aq. phase or steam to give an oxide layer of 0.5-7 mu thickness and ensuring adhesion of Zn corresponding to 100-275 N/cm2. The Al cathodes are anodically oxidised and the layer is treated with salt-free water or an alk. chromate soln. at 90-100 degrees C. The Al cathodes are anodically oxidised in a sulphuric acid soln. to give an oxide layer of max. 10 mu thickness, and the layer is made denser by treating with an alk. chromate soln. contg. 50-100 g/l K2Cr2O7 and 10-20 g/l NaOH at 90-100 degrees C, or steam at 100 degrees C for max. 3 min. The treated Al surface is then washed in water at 40-60 degrees C.

Title: Water supply pressure booster for high buildings - has pumps with delay valves preventing pressure surge on restarting
Inventor: STAMPA BURKHARD DR
IPC: E03B5/02
Filed: 1976-01-24
Abstract: The pressure boosting system is used in the water supply system for high rise buildings. One or more pressure increasing pumps are connected by a nonreturn valve directly to the water supply system. The performance is improved by automatically working fittings arranged on the pump outlet. It prevents maximum possible pressure surge which occurs when the pumps are reconnected after a failure. The outlet of each pressure increasing pump has a starting valve which is closed automatically when the pump is switched off. This valve opens with a delay when the pump starts. The starting valve is a nonreturn valve whose closure element is connected with a hydraulic or pneumatic damping cylinder with restoring spring or with a damping spring.

Title: Toy railway two point bearing coupling - has coupling block located in horizontal plane by spring engaging central eye
Inventor: BREMER KURT
IPC: A63H19/18
Filed: 1976-03-15
Abstract: The 2-point bearing coupling block for toy railways has 2 vertical pivot points (L, R) equidistant from the centreline, against which it is held by a spring engaging in a central eye (F). This spring exerts horizontal tension and thus also determines the block horizontal location. Running through curves, the sideways load on the coupling causes it to rotate about one or other of the pivots, increasing the distance between the coupled cars as well as the tension in the spring. Sudden load changes, causing jerky movement , are thus avoided.
Patent DE-2614783-A1 (DE)
Title: Sound recorder with selective fade-in of microphone signal - has control time constant switching simultaneously reverting to lower value
Inventor: CRANTZ DIETER DIPL ING
IPC: H03G3/20
Filed: 1976-04-06
Abstract: Switches selectively fade in the microphone signal during recording of the music signal. A switching operation ensures simultaneously that the control time constant is reversed to the low value, that the level of the music signal is reduced and that the microphone is connected operatively to the sound recorder. The switching facility can be a mechanical switch and at least one diode. A relatively low resistance can be switched, via a switch, parallel to the RC element determining the larger control time constant, so that the small control time constant is determined.
Patent DE-2616951-A1 (DE)
Title: Jib crane tipping moment limitation device - uses stretching or compression load in supporting surface to compute value
Inventor: SCHILL RICHARD
IPC: B66C23/90
Filed: 1976-04-17
Abstract: The tipping moment limitation device is for jib cranes, including slewing ones, and similar machines. The stretching or compression of the material in the supporting surface at the slewing ring or anchorage points is used by a computer to calculate an actual value, proportional to the total tipping moment at the tipping point of the crane. The stability base of the crane can be taken as a variable value when determining this actual value. To emit a signal on reaching the max. tipping moment the actual value can be compared with a desired one proportional to the crane stability base.

Title: Temporary detachable railway vehicle track switching device - has unbroken main track and detachable rail pieces laid at intersection gaps
Inventor: PERROT ROBERT
IPC: E01B7/00
Filed: 1976-10-29
Abstract: The function of the detachable device is the guided transfer of rail vehicles from a main track to a branching track, or vice-versa. This is provided esp. where the divergence is only occasionally used, so that loading takes place only when vehicles or trains are actually being switched. The main track (1) is laid without a brake, while the branching track (2) is laid without direct connection to the diverging areas (3) and intersection area (4) between itself and the main track. Detachable pieces of rail are fitted in these areas, at least, to effect guided vehicle transfer. These can be laid partly on the rails of the main track, and fastened to lengthways sleepers attached to the sleepers of both tracks.

Title: Welding heat resistant alloy rings onto poppet valves - via automatic machine, where valves are for use in IC engines
Inventor: MOZSCHUCHIN ANATOLY ALEKSANDRO
IPC: B23K13/00
Filed: 1977-04-26
Abstract: Plant for deposition welding is esp. for welding a ring (a) made of heat resistant alloy onto the working surface of a poppet valve (b) intended for an IC engine. A row of the valves with stem pointing downwards flows down an inclined chute; and a row of rings (a) flows down a second chute. A manipulator successively removes one valve (b) and one ring (a) from the two chutes. The manipulator turns each valve so the stem of the latter points upwards, and moves the ring against the valve. A swivel plate fitted with a loader, spray quenching nozzle, and discharge pipe for the welded assembly (a, b) is used in conjunction with the manipulator and swivels between three positions. The loader lifts the valve stem up through a ring induction heating coil so the setm enters a chuck which rotates during welding. After welding, the quenching nozzles is used and the assembly (a, b) is then released from the chuck so it enters the discharge pipe. Used for high speed mass prodn. of valves for IC engines.
