Title: Machine to chamfer teeth edges of gears - has spindle driven by servo motor and moved to=and=fro by piston-cylinder unit whose movement is controlled by servo valve
IPC: B23F19/10
Filed: 1991-12-04
Granted: 1992-12-10
Abstract: The machine has a workpiece spindle (1) with a drive (7,8) which incorporates a servo motor. The rate of rotation of the spindle, which is either continuous or in steps, is determined by a controller (2). The spindle can be moved to and fro by a piston-cylinder unit. This movement is controlled by a servo valve (22) and is in synchronisation with the rotation of the spindle. The spindle (1) is mounted in a sleeve (3), which is connected to the rotary drive and in which it can move over the required stroke. It can be connected to the sleeve by a coupling (9). The piston (14) is mounted on the end of the spindle which protrudes from the sleeve and moves in a cylinder (20). The piston moves together with the spindle (1) when operated by the servo valve. The actual movement of the spindle is detected by the controller so that it can operate the servo valve. USE/ADVANTAGE - Several types of chamfer can be given to the workpiece e.g. the edges can be rounded. No additional drive or gear change, step drive or control curves are required.

Title: Method of producing three=dimensional object free from distortion - by successively photo curing layers of liquid or powder under control of computer which differentiates between each core and outer skin
Inventor: REICHLE JOHANNES
IPC: B29C67/00
Filed: 1993-03-24
Granted: 1993-11-25
Abstract: A three-dimensional object is produced by successively solidifying a series of layers of a liq. or powder by elecromagnetic irradiation. Each layer is broken down into an inner core part and an outer cover part, and the irradiation is controlled so that the core and cover parts have different properties. The method uses the principle in stereolithography i.e., where successive layers of polymer are photo-cured e.g, by laser to form a laminar shape. ADVANTAGE - The procedure minimises any distortion of the object produced. It produces high grade surface finishes to close tolerances. It minimises consumption of material and time required.
Patent DE-4322924-C1 (DE)
Title: Method and apparatus for the production of hot-rolled carbon-containing steel strip
Inventor: FIGGE DIETER DIPL ING
IPC: C21D7/13
Filed: 1993-07-05
Granted: 1994-10-27
Abstract: The invention relates to a method and an apparatus for the production of hot-rolled carbon-containing steel strip from feedstock continuously cast in strip form with a thickness between 25 mm and 4 mm, which is introduced at speeds of between 3 m/min and 80 mm/min in a continuous process into a continuous rolling mill with at least two roll sets with a minimal spacing and is reduced between the roll sets at temperatures above 880 DEG C and under tension. In order to permit a method of this kind to be employed with little expenditure of energy and with low investment costs for the production of a strip which is suitable without annealing for cold deformation, the invention proposes the following three steps: the strip leaving the two roll sets is deformed in a third reduction pass at a finishing temperature of 810 DEG C to 790 DEG C, this deformation taking place in the gamma region because of the downward shift of the transformation point; the strip deformed in this way is then cooled rapidly to below the A3 transformation point to a temperature of about 650 DEG C and is finally wound into a coil in which the recrystallisation of the strip structure takes place at about 600 DEG C.
Patent DE-4337110-C1 (DE)
Title: Method and device to operate a defibrillator
Inventor: DIETL MICHAEL A J
IPC: G06F17/00
Filed: 1993-10-29
Granted: 1994-11-03
Abstract: The invention concerns a method and device to operate a defibrillator efficiently. The defibrillator is in the form of a semi-automatic device which has a neural network which is operated in the forward path. The network parameters are stored on an exchangeable memory card, and the memory card is used for temporary communication with an external personal computer. The memory card also contains the electrocardiograms which are recorded during use of the defibrillator, and which are transmitted to the personal computer together with the network parameters. Automatically or manually evaluated electrocardiograms are taken into a development database of the personal computer, and these electrocardiograms are used in the personal computer to execute a learning process, i.e. operation of a neural network in the backward path. The learning process results in new network parameters, which are tested for efficiency using a defibrillator simulation program and data from a reference or standard database which is internal to the personal computer. If the result of the efficiency test is positive, the new, updated and thus optimised network parameters are written back to the memory card and transmitted to the defibrillator, so that the next time it is used the neural network in the defibrillator works with optimised network parameters.

Granted: 1995-08-10
Abstract: The cylindrical and hollow fireproof brick, such as for the grid structure of chambers in a glass smelting furnace, has a circumference (U) of eight adjacent and angled surface sections (12f,14f). Each pair of surfaces are parallel to each other, forming a centre channel (20) coaxial to the central longitudinal axis (M), with the diametrically facing inner surfaces parallel to each other, of the eight inner surfaces. In each of the eight sections (12a-12d; 14a-14d), their outer and inner surfaces are parallel to each other. The angled brick wall sections (14a-14d) have a thickness (D2) which is 15-25% thinner than the thickness (D1) of the sections (12a-12d) between them. The hollow brick (10) structure is such that a rotation of 90 deg  round the centre axis (M) restores the original geometry.

Granted: 1996-04-25
Abstract: The invention relates to a fast shutdown system (1) for a nuclear reactor (2) having a reactor core (3) and a plurality of control rods (4) which are arranged side-by-side and may be inserted into a and withdrawn from the core (3). The control rods (4) have a plurality of operating groups (5a, 5b) into which the control rods (4) are fitted to control the power of the nuclear reactor (2) and a number of shutdown groups (7a, 7b) into which the control rods (4) are fitted to shut the nuclear reactor (2) down rapidly. Control rods (4) from at least two operating groups (5a, 5b) are allocated to each shutdown group (7a, 7b) and/or control rods (4) from at least two shutdown groups (7a, 7b) are allocated to each operating group (5a, 5b). Such an arrangement of the control rods (4) in shutdown groups (7a, 7b) and operating groups (5a, 5b) ensures, even when not all the control rods (4) have been withdrawn on a start-up of the nuclear reactor (2), that on fast shutdown with the failure of control rods (4) of a shutdown group (7a, 7b) to enter, at least some of the control rods (4) already withdrawn are reinserted into the reactor core (3). Preferably there are two shutdown groups (7a, 7b), in which a single hydraulic insertion system (6a, 6b) is allocated to each shutdown group (7a, 7b). The invention also relates to a process for the fast shutdown of a nuclear reactor (2).
