Title: Hydraulic tool-clamp to rotary mandrel - has wedge-pieces thrust radially to force main body and annular piston apart
Inventor: BAUR MANFRED
IPC: B23B31/30
Filed: 1992-09-26
Abstract: The main body (1) of the clamp rotates with the mandrel (3), and has an annular groove (5) into which an annular piston (6) protrudes. A piston (9) works in a pressure chamber (8) inside the body, and supplies pressure to the annular groove. Wedge-pieces (20), seen in axial section, have faces inclined to the clamp axis and work against pairs of mating ones (21,22), being thrust in the radial direction by clamping members (23). They are so mounted between the body and the annular piston as to thrust them apart in the axial direction, the piston being held in position in the radial direction. One of the faces in a pair can be formed by the body, and the other by a supporting body. USE/ADVANTAGE - Running out of true of tool clamp is prevented, or is rapidly and simply corrected.

Title: Braking mechanism for HV switching device
Inventor: BOETZER GUENTER
IPC: H01H3/60
Filed: 1992-10-08
Abstract: The switching action for a high voltage device has an actuator shaft (1) moved by a loaded spring unit (2). The shaft moves a cam disc (3) to displace a roller follower coupled to the switch. The rotary motion stops when a limit lever (5) engages a stop. Mechanical clearance is provided between the cam and the spindle. This is in the form of play between an internal gear coupling. This reduces the load on the limit lever when the stop is engaged.

Title: Bore-sealing ring
Inventor: MUECHER HORST A
IPC: F16L41/08
Filed: 1993-02-10
Abstract: The bore-sealing ring - known as "bore ring" (4) by specialists - which is necessary for the sealed insertion of a connection stub (1) into a principal pipe (3) exhibits a sealing part (7) and a sealing leg (8) in addition to its radial collar (6).

Title: Photocatalytic oxygen-iodine laser
Inventor: BRANDT ORTWIN DR
IPC: H01S3/22
Filed: 1993-03-15
Abstract: The invention relates to a photocatalytic oxygen-iodine laser for generating high-intensity continuous or pulsed laser radiation with a wavelength of 1.315  mu m. The upper laser level is, along the lines of a transfer laser, populated with <1> DELTA  oxygen in bursts. The required <1> DELTA oxygen is generated photocatalytically by the action of light on fullerenes (especially C60 and C70), which give up energy to the oxygen in the ground state (<3> SIGMA ). A closed gas circuit presents no problem. In contrast to chemical oxygen-iodine lasers, a substantial technological simplification results. Problems with feed stock such as hydrogen peroxide and chlorine are completely dispensed with.
Patent DE-4308498-A1 (DE)
Inventor: BINDER WOLFRAM DR
IPC: A23K1/00
Filed: 1993-03-17
Abstract: 2. Animal feed additives based on fermentation broth further contain, in addition to the additive, other fermentation broth constituents. Such products, after spray-drying, generally have an excessively low bulk density and/or are sticky. To granulate these products, processing aids have therefore been added, e.g. perlite or sawdust. Alternatively, such products have been dewatered by azeotropic distillation with paraffin oil to give granules. The object of the invention is a highly concentrated animal feed additive which, in particular, is to have a bulk density of at least 550 kg/m<3> and a standardisable active compound content. 2.2. By pelletising, stable granules can be produced from an animal feed additive-containing fermentation broth if the fermentation product is contained at at least 33% by weight. Granules can particularly readily be produced by pelletising if the pellets are built up of at least 30% by weight fine grain with at least 70% by weight having a particle size < 100  mu m. The biomass can be contained completely, in part or not at all in the granules. 2.3. Animal feed additives such as lysine, threonine or tryptophan, or containing fermentation broth products.

Abstract: In a pot filler for foodstuffs and semi-luxuries, especially for low-viscosity to pasty dairy and fat products or the like, the conveying chain has driving chains. Every two drivers adjacent to one another form between them a pot receptacle grasping a first pot side. The second pot side is held on a rectilinear lateral guide extending in the conveying direction. The pot bottom is supported on a rectilinear bottom guide extending in the conveying direction. A pot-feed station preceding the driving chain has a feed-conveyor means, which feeds the pots in web form and supports them at the bottom and which is arranged laterally next to the space of movement of the driving chain, and an intermediate conveyor means connected to the feed-conveyor means. The intermediate conveyor means transfers each pot into a pot receptacle by means of a transverse movement.
