Patent CH-666434-A5 (CH)
Title: Chuck to drive workpiece held between centres - has work clamp jaws each carried by two leaf springs forming parallelogram linkage
Inventor: ABBUEHL HERMANN
IPC: B23B33/00
Filed: 1985-05-02
Abstract: The chuck for driving a workpiece (1) held between centres comprises work clamp jaws (2) each carried via at least two leaf springs (3) which form a parallelogram linkage axially movable by the end of an actuated co-axial tube (7) in the drive spindle to open and close the jaws in radial directions through  deformation of the springs. The spring force provides clamp  action. The jaws complete with leaf springs are preferably driven via a torsionally rigid coupling (6) operating without exerting lateral forces. ADVANTAGE - The arrangement ensures uniform and accurate centric jaw clamp action unaffected by dirt ingress as experienced with jaws adjustable in guide ways.

Patent CH-668815-A5 (CH)
Title: Automatic emptying valve for water tank - has adjustable position ballast weight and water pressure opened valve
Inventor: HOTZ PAUL
IPC: F16K21/18
Filed: 1985-05-31
Abstract: The outlet in the bottom of the tank is closed by a valve (2) pulled upwards into the sealing position by a vertical shaft (3).  The shaft is linked to one end of a yoke lever (3), the other end of which has a ballast mass (6) moving between two stops (9. 8). The valve is opened by the water pressure pushing open the valve. This causes the yoke to tilt and the ballast mass to move to the stop (8) nearer to the pivot.  This imparts a  lower drag on the shaft and allows the water to drain to a set lever  The valve then closes and the mass moves back to its original position. USE/ADVANTAGE - Simple mechanical valve, water levels adjusted by stop settings.

Title: Pre-bent sheet metal wall coping - is fitted to flanges of U=section cover on parapet wall
Inventor: PICHLER KARL
IPC: E04F21/00
Filed: 1984-07-16
Abstract: The mechanism fits a sheet metal, e.g. copper, stainless steel or aluminium, coping element over the already placed U-section sheet metal cover secured, e.g. by screws and plugs, to the upper surface of a parapet wall or the like whereby this element has its lateral edges already partially bent (7) before fitting. It comprises a square-section vertical tube (8) with square-section bush (9) slidably adjustable (13) thereon, a frame (12,10) slidably adjustable (14) on the bush and having a horizontal member (10) bent downwards at its end, and a roller (11) rotatable on a horizontal shaft (22) with its ends carried (15,16) by the bush (9) and the downward end respectively.  An L-section (21) on the lower end of the tube has its vertical flange pivoted to the centre of a horizontal swivel lever (17) of which the ends carry two profile rollers (19,18), one (18) with a 60 deg. cone and the second with a 45 deg. cone.  The arrangement is such that, by manually (8,10) moving the suitably adjusted (13,14) mechanism along the coping element, the pre-bent edge (7) is folded-in between the rollers (11; 18,19) over the downward flange of the already secured sheet metal cover. USE/ADVANTAGE - The mechanism simplifies fitting the upper coping element on a wall by folding the pre-bent portions inward through a 45 deg. upward angle over the flanges of the fixed cover to form the 'drips', an operation normally carried out using hammer and pliers.

Granted: 1995-12-05
Abstract: A stabilized pharmaceutical composition containing paclitaxel, teniposide, camptothecin or other antineoplastic agent susceptible to degradation during storage is produced using a solvent system containing a low carboxylate anion content. The solvent system is a mixture of ethanol and a polyoxyethylated castor oil.
