Patent CH-665567-A5 (CH)
Inventor: OLGAARD AXEL
IPC: B01F27/71
Filed: 1984-09-20
Abstract: Aerator for aerating air in a liquid (12) in a treatment vessel (7) comprising a motor (1) driving a propeller (4) a Venturi nozzle (2) being placed right behind the propeller (4). When the propeller (4) rotates, an air flow will take place through the Venturi nozzle (2), and this flow will sweep along air from an air hose, said air aerating said liquid efficiently by means of the propeller (4). Moreover, a strong effect on the direction of the flow is achieved in order that good circulation in the vessel (7) will take place while being operated in order that even and efficient aeration is attained.

Title: Photographic cassette for large camera
Inventor: KOCH CARL
IPC: G03B17/32
Filed: 1986-09-03
Abstract: The photographic cassette for the handling and exposure of a light-sensitive sheet, particularly in a large camera, has a flat housing (31) with opening (32) on one side controlled by an exposure slide (33), the latter also allowing passage of the sheet when loading and unloading the cassette.  A support face (53) bears against the rear sheet surface, while holders (56,57) securing the sheet edges are movable out of its path by an actuator (81) operated from outside. The support face is on a spring-loaded pressure plate thrust towards the opening so as to clamp the sheet against the holders.  The actuator has a control member forcing the plate back against spring action, so as to leave a gap between it and the holders.

Title: Process for the preparation of novel 2-tetrahydrofurfuryl-6,7-benzomorphans
Inventor: MERZ HERBERT DR
IPC: C07D405/06
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; and   R<3> denotes hydrogen or methyl are prepared by cyclising appropriately substituted tetrahydrofurfurylbenzylpiperidines in the presence of acidic catalysts. 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 exhibiting the undesired side effects of morphine, e.g. the addictive action. <IMAGE>

Title: Lifting rope operated hydraulic actuator for grab - has rope driven hydraulic pump for operating grab jaw actuating cylinder
IPC: F04B9/02
Filed: 1975-05-12
Abstract: The hydraulic actuator of a grab is actuated by a rope system which drives the hydraulic actuator of the gra jaws. The lifting arrangement of the grab with two ropes is utilised for actuating the hydraulic pump. The rotating driving wheel within the housing is driven by chains connected to the ends of the lifting rope. The movement of the lifting rope rotates the wheel which is coupled to the hydraulic pump (7). The delivery direction of this pump is also changed when the rope travel changes direction. This pump may not be reversible and in this case a multiway valve is actuated by the rotating direction of the driving wheel.

Title: Explosion initiator of the percussion type - for automatic weapons
IPC: F42C19/08
Filed: 1972-03-03
Granted: 1973-10-12
Abstract: Initiator comprises at least one explosive charge contained in an envelope which is rigid but is destroyed on firing. In artillery of a high calibre the explosive charge is usually contained in powder-bags but with modern automatic weapons a rigid case is necessary; this involves the use of a complex ejection system with, in consequence, dead time in the firing sequence. In the new device the envelope for the charge can be made either in combustible, friable material, such as wood or cardboard, in a completely combustible plastic material or in an envelope made from an explosive with a plastic binder. The initiator is partic. useful for automatic weapons with a high rate of fire in which bare propellant charges are used to eliminate the need for an ejection system. The envelope itself may be made of an explosive material of the same chemical compsn as that of the explosive charge contained in the envelope.

Title: Jointing seal for large dia. concrete undersea piping - has compensation for misalignment of pipe ends
IPC: F16J15/46
Filed: 1973-03-20
Granted: 1974-11-22
Abstract: The joining faces of the two pipes have annular grooves of the same dia. At the bottom of each groove is an inflatable ring which can be inflated from the exterior of the pipe, and on this ring is positioned a sealing ring which will slide axially in the groove. Applying pressure to the inflatable tubes, the seals move out of the grooves and one which has a 'T' form enters the other which has a 'U' form and seals the joint. All rings are positioned in grooves before submersion. The 'T' seal can be equipped with cutting knives to cut through the base of the 'U' seal and the inflatable ring, the seepage of hydraulic fluid under pressure diving a better seal between the two rings.
