Patent CH-616915-A5 (CH)
Title: Process for the preparation of oximes
Inventor: MOUDRY RADOMIR DIPL ING CHEM
Filed: 1975-04-15
Abstract: In the conversion of ketones to oximes using hydroxylamine sulphate in a cyclic process, the sulphuric acid formed is neutralised by means of a metal oxide or metal hydroxide with the formation of a metal sulphate which is readily thermodegradable. The metal sulphate is cleaved thermally to give metal oxide and sulphur dioxide. These two cleavage products are recirculated to the cyclic process (after the sulphur dioxide has been converted into sulphuric acid). This process avoids the production of by-products which can only be utilised to a very small extent, such as ammonium sulphate, which means that the process is environmentally friendly.
Patent CH-672565-A5 (CH)
Inventor: KONRAD BERNHARD
IPC: H02J13/00
Filed: 1986-12-09
Abstract: A transmitter with controlled switches for use in a process for the generation of transmission current signals in an alternating current distribution network is connected to the supply network. When operated, this transmitter generates a series of current impulses. The moments in time of the generation of these current impulses and/or their duration are so chosen that the resulting transmission signal corresponds at least approximately to a desired theoretical signal. The transmitter contains at least two energy storages or energy storage devices and at least two switches for controlling the energy exchange between the two storages. These switches are so controlled that the exchange current flows through the mains, whereby the aforesaid current pulses are generated. It is thereby possible to use substantially only loss-free elements for the transmitter. The main field of application of the transmitter lies in ripple control technology, where it may be used as a transmitter in a central station (center) or as a transmitter for return signals to the center and for remote reading through the network of distributed meters with return signalling of the state of the meters to a center.

Title: Security lock with key and keyhole in circuit - has electric controller for bolt and alarm to open correct key
IPC: G07C9/00
Filed: 1973-07-20
Abstract: The security lock of which the key and the key recipient constitute complementary parts of a circuit, is designed to obviate key copying and decoding. The circuit controls both the bolt and an alarm system to the effect that introduction of the correct key authorises unlocking, and any other manipulation initiates the alarm system. The lock constitutes two circuits fed from characteristically differing sources. All components are traversed by currents of an intensity within a definitive range when the correct key is used, thus authorising unlocking. The manifestation of abnormally intense currents effects the alarm in all other instances.

Title: Two axis centrifugal sepn - of lead from vehicle exhaust gas
IPC: B01D45/14
Filed: 1970-06-19
Granted: 1972-02-04
Abstract: A centrifugal sepn. process, esp. for removing lead from exhaust gas, uses two centrifugal fields, the axis of the 1st. rotating about that of the 2nd. at 80-90 degrees to it. In a prefd. apparatus, the 1st field is produced by a cyclone, (or several cyclones) with its axis radially mounted on a rotor (the 2nd field). Rotation of the rotor assists rejection of the separated heavy constituents along the axis of the cyclone, radially outwards from the rotor, while the lighter constituents move radially inwards. Exhaust gases enter the cyclones tangentially.
