Patent CH-620440-A5 (CH)
Title: Process for the preparation of 2-tetrahydrofurfuryl-6,7-benzomorphans
Inventor: MERZ HERBERT DR
IPC: A61P25/04
Filed: 1979-04-24
Abstract: Novel 2-tetrahydrofurfuryl-6,7-benzomorphans of the formula I, in which     R<1> denotes methyl, ethyl or propyl;   R<2> denotes hydrogen, methyl or ethyl;   R<3> denotes hydrogen or methyl; and R<4> denotes hydrogen, alkyl having 1 to 4 carbon atoms, or acyl having 2 to 5 carbon atoms are prepared by removing water from appropriately substituted 2,5-dihydroxy-n-pentylbenzomorphans with closure of the tetrahydrofuran ring. The resulting bases of the formula I can then be converted into their acid addition salts. The compounds of the formula I and their acid addition salts are distinguished by a therapeutically utilisable action on the central nervous system. Particularly to be emphasised is their analgesic action, which frequently excels that of morphine, without the undesired side effects of morphine, e.g. the addictive action. <IMAGE>

Title: Automatic control for resistance filament mfr. - continuously operating and reduces reject level
IPC: H01C17/00
Filed: 1973-06-06
Abstract: The automated control system for filament drawing and cutting in a continuously running process, results in electrically resistant fibres having diameters between 0.15 and 3.0 mm and length of between 3.0 and 6.0 mm and can produce about 10,000 pieces an hour. The reject rate using the proposed automatic control system is reduced considerably from the normal 60 to 70% level. As the filament passes through the sequential step-by-step drawing stages its transverse resistance is measured and compared with a required level using a 50Hz bridge, the output of which ultimately controls the rate of deposition of material onto the drawing collars.

Title: Method for digital control of the thyristors of a thyristor DC pulse converter, and a device for carrying out the method
Inventor: KALINICHENKO ANATOLY YAKOVLEVI
IPC: H02M1/084
Filed: 1978-09-15
Abstract: The opening time of the thyristors of each phase of the m-phase converter is controlled by pulse sequences and further pulse sequences which are shifted in time with respect thereto. The pulse sequences are offset by <1> DIVIDED m from phase to phase. The control channels of all the phases are connected successively to the thyristors corresponding to the successive reaching of the maximum limiting value of the control zone of each control channel. The device contains a control generator (1) which is connected to a decoder (7) for unshifted pulse sequences and to the logic inputs of decoders (3 to 6) for shifted pulse sequences. The information inputs of these decoders (3 to 6) are connected to the information outputs of a reversing counter (9), and the outputs are connected to one of the information inputs (131 to 134) of a matching unit (14). Groups (15 to 18) of logic AND gates, each having four gates are provided. One input of the l-th logic AND gate of each of the groups (15, 16, 17 or 18) is connected to the output of the decoder for the l-th shifted pulse sequence, and the outputs of all the logic AND gates of the first to fourth groups (15 to 18) are connected to the control outputs (201 to 204) of the reversing counter (9). <IMAGE>

Title: Chopped vegetable pelletising unit - has electrostatic charge in material reduced or fluid added to increase cohesion
IPC: B30B15/00
Filed: 1975-09-23
Abstract: Pressings, made from chopped up vegetable material such as straw or sugar cane and which are used as animal food, often break up during transport or storage. The cause for this breaking up can be traced back to the fact that the pressing contains too much entrapped air. during dry conditions, electrostatic charges on the chopped up particles also tend to retain this air. To reduce the amount of air in the pressings and improve their strength, the particles are wetted with water to which a wetting agent is added in addition or as an alternative the static charge on the entrapped particles is neutralised air can further be reduced by squashing the particles.

Title: Centrifugal casting highly oxidisable metals
IPC: B22D21/02
Filed: 1969-08-25
Granted: 1971-05-14
Abstract: Metals which are highly oxidisable in the molten state, partic. Al, Mn, and their alloys are centrifugally cast in a mould centrally filled while in rotation. The mould has vanes or channels radiating around a central cavity which help the metal to flow non-turbulently towards the periphery of the rotating mould.

Title: Lock with barrier for its gates - beam pivoted at its ends deflects to absorb shock from a barge
IPC: E02C1/10
Filed: 1973-07-27
Granted: 1975-02-21
Abstract: The barrier is capable of withstanding blows from a ship with kinetic energies of up to 280,000 joules. A beam (5) obstructs the channel beyond the lock (1). The width (e) of this box beam is related to the width of the channel. Either end of the beam is joined to a steel bracket (6) by means of pivots (8). These brackets are seated in grooves in the sides of the channel (3). These grooves enable the barrier to be lowered when it is not required. When a ship hits the barrier it moves the beam towards the lock and causes the side members to pivot. This movement is opposed by two pistons (14).
