Patent CH-633586-A5 (CH)
Title: Chemical metallising or metal recovery - by contacting hot surface with soln. of metal salt and reducing agent
Inventor: DELMONTE JEAN
IPC: C23C18/52
Filed: 1979-09-25
Abstract: In the chemical metallising of a workpiece by contact with a soln. of a metal salt and a reducing agent, the workpiece is heated to a temp. higher than that of the metallising bath. The process is useful in the chemical deposition of a wide range of metals and alloys (Fe, Ni, Co, Cr, Pt, Pd, Au, Cu, As, Ag, Sn, Pb and Rh), and removal or recovery of metals (e.g. Ag, Cu, Au, Co and Ni) from spent electroplating or chemical plating baths. Heating of the workpiece rather than the bath allows use of plastics (e.g. polyethylene) instead of stainless steel or titanium for the plating tank, reduces heating energy consumption, avoids the need for costly heat exchangers, allows simpler more stable plating solns. to be used, reduces the content of phosphorus or boron (from the reducing agent) in the deposit, permits a wider variation in bath compsn. and pH, allows higher deposition rates (up to 60 microns/hr. or more), allows all plating steps (including pre- and post-treatments) to be carried out in the same installation, and allows the last traces of metal to be eliminated from spent baths.

Patent CH-568054-A5 (CH)
Title: Pressure cooker with bayonet locking lid - has safety device for preventing inadvertent opening of pressurised cooker
IPC: A47J27/092
Filed: 1973-08-16
Abstract: The pressure cooker has a safety feature which ensures that the cooker lid cannot be removed inadvertently while the cooker is under pressure. The lid (2) has a tilting element (6) which is rotated about an axis (7) tangential to the lid circumference. When the cooker is pressurised the seal lips (3) are pressed apart, and the lip (3b) exerts pressure on the tilting element end so that this element is moved into the locking position against a bayonet lock member and the lid cannot be rotated. The locking is indicated by the raised end of the element which projects out of its seat. The cooker can be pressurised by pressing down the element so breaking the seal.
Patent CH-567190-A5 (CH)
Title: Pump with bypass for liquefied gases - has motor cooled by liquefied gas drawn from pump outlet
IPC: F04D29/06
Filed: 1973-08-21
Abstract: A quantity of the pumped gas is tapped from the outlet end for the lubrication and cooling of the motor, before recirculating. The rotor shaft (3) has an auxiliary rotor (4) above the main impeller. The motor chamber (6) is separated by this rotor impeller to form two chambers. The tapped liquefied gas is supplied into the lower chamber through a pipe connected to the downstream outlet of the main impeller. This gas is pumped through the motor gap between the rotor and the starter and it passes past the rotor bearing and into the outlet pipe which is also connected to the downstream pipeline adjacent to the tapping pipe connection. The system prevents excessive temp increases in the motor and in the bearings.
