Title: Apparatus for detaching surgical blades
Inventor: QUEK KIM SIA
IPC: A61B17/3217
Filed: 2018-02-14
Granted: 2019-06-27
Abstract: An apparatus for detaching a blade from a scalpel handle is provided. The blade has a cutting portion and a heel portion and is removably mounted on a tang of the scalpel handle. The apparatus has a flexible blade detachment member with a stepped portion for engaging the heel of the blade as the handle is withdrawn and a leading angled portion. A backing member is provided with the detachment member being arranged adjacent the backing member so that during use the detachment member flexes in only one direction, away from the mounting tang in response to force applied by the handle to the leading angled portion thereby causing the blade and the handle to be separated and detached relative to each other. Upon withdrawing the tang from the opening, the stepped portion engages the heel of the blade resulting in detachment of the blade from the tang.
Patent DE-102007012316-B9 (DE)
Inventor: GROS-WEEGE JOHANNES
IPC: B21D5/10
Filed: 2007-03-09
Granted: 2009-06-10
Abstract: The invention relates to a method for bending a plane metal sheet to be shaped into an open seam tube, in a bending press (11) comprising an upper tool fixed in the press frame (4) and having a contour corresponding to the bending contour to be achieved, and a vertically mobile lower tool (3) arranged opposite the upper tool (1). The edge strip (3) of the metal sheet fixed in the press frame (4) is bent between said tools in a working step in order to create the desired edge contour. At the beginning of the bending process, the working surface of the lower tool (3), which comes into contact with the lower side of the edge strip (3), takes its bearing in a flat manner in the form of a Hertzian compression. In order to prevent the formation of ridges and plastic deformations or crushing, said flat contacting is to be maintained at a minimal distance from the edge of the metal sheet, at a constant distance therefrom in relation to the point of application of force (P), during the entire bending process, by means of a co-ordinated horizontal and vertical movement of the lower tool (3). The bending press (11) provides a constructive solution for carrying out said method.

Granted: 1987-03-05
Abstract: In an articulated bus, the driver can no longer view the rear right-hand door (38) forward and to the left from his driving position (24) via the right-hand rear mirror if the articulated bus bends to the right beyond a specific degree, i.e. the front part (10) of the vehicle is swivelled in the anti-clockwise direction.

Title: Working method for the deep-drawing of metal sheets, and a deep-drawing press which carries out this method
Inventor: KRUSE ALBERT
IPC: B21D22/02
Filed: 1986-07-10
Granted: 1987-09-10
Abstract: The invention relates to a working method for the deep-drawing of metal sheets, and to a deep-drawing press for carrying it out. In this working method, two tool parts are moved towards one another and the rim of the sheet to be deep-drawn is clamped, before the beginning of deep drawing, between a hold-down device, which moves with one tool part and which can be displaced relative to the latter in the lifting direction against a defined resistance, and the rim area of the other tool part, the countertool. With the tool opened, the hold-down device is here advanced towards the countertool in relation to an - imaginary - relative position of the hold-down device at the beginning of deep drawing. In order to reduce the noise emitted when the hold-down device, the countertool and the sheet arranged between them strike one another, the invention envisages that the hold-down device should be moved towards the tool part associated with it before it strikes the countertool so as to reduce the approach speed of the hold-down device and the countertool.

Granted: 1989-01-12
Abstract: In order to connect a fire-resistant moulding (6) and a sealing moulding (10) to a case (2), the latter is formed from a case profile which exhibits two grooves (5, 9). For this purpose, the case profile is produced from sheet-metal material of a thickness of less than 3 mm. In order that the case (2), despite the low sheet-metal thickness, can nevertheless fulfil its load-bearing and reinforcing function to a satisfactory extent, there is arranged, on that side of the case (2) which is directed away from the doorleaf (1) at least one reinforcing profile (14a) which is welded, over its cross-section, in sections to parts of the case surface and otherwise runs at different distances with respect to parts of the case surface, with the result that the latter obtains, in the region of the reinforcing profile (14a), a sandwich-like structure which is distinguished by a high degree of loadability. <IMAGE>
Patent DE-3903319-C1 (DE)

Granted: 1990-03-29
Abstract: Process and device for filling and distributing cheese curd in rough-pressing or final-pressing basins (1) including a filling and distributing device (3), whose feeding elements (3b) have ends which dip into the whey contained in the rough-pressing or final-pressing basin (1) in all of the operational positions, and which is connected to a cheese curd storage container, from which it is fed by means of a conveying device. The aim of the invention is to ensure a regular and smooth supply of cheese curd, free from trapped air, to the rough-pressing and final-pressing basin (1). To this end, the level of the whey in the filling and distributing device (3) is raised relative to that in the rough-pressing and final-pressing basin (1) by generating an underpressure in the head of the former (3); the cheese curd is distributed over the whole of the width of the basin, whereby it sinks inside the whey column, from its point of admission to the basin. The device for implementing this process includes in particular a distribution housing (3a) which extends over the basin (1) perpendicularly to the direction of flow, whose lower part opens out to a channel (3b) over the whole of its length and whose upper part is connected with a ventilation housing (3c).

Title: One piece aluminium@ alloy wheel prodn. - by soln. annealing, quenching to working temp., extruding or rolling and then age hardening
Inventor: KLEIN HORST
IPC: B21D53/26
Filed: 1993-02-19
Granted: 1994-03-10
Abstract: In the prodn. of a one-piece wheel of age-hardenable wrought aluminium alloy, in which a hot blank is extruded or rolled to a finished prod. and in which soln. annealing is carried out at 530 deg.C., followed by quenching and age hardening at 150-200 deg.C. the novelty is that after the blank is soln. annealed, it is quenched in a controlled manner to 290 deg.C. extruded or rolled to the finished prod. at this temp. without significant reheating and then artificially age hardened. ADVANTAGE - The process avoids wheel distortion, caused by quenching and subsequent turning, and reduces energy costs since reheating from ambient temp. to the working temp. and to the age hardening temp. is not required.

Title: Michelson-type interferometer
Inventor: TANK VOLKER DR
IPC: G01J9/02
Filed: 1993-07-07
Granted: 1994-10-13
Abstract: The interferometer according to the invention has, apart from a beam splitter (2), a converging lens (9) and a detector (10), six plane mirrors (3a, 3b; 4, 5, 6a, 6b) and a plane-parallel plate (7), which is mirrored on both sides, as rotating mirror element. The axis of rotation (8) runs concentrically to the mirror element (7) and is inclined with respect to the normal to the mirror element (7) by the angle  alpha . Half-beams coming from the beam splitter (2) are deflected via plane deflection mirrors (3a, 3b) to the mirror element (7), reflected by the latter to the plane mirror (4) arranged perpendicular to the axis of rotation and run from there through an un-silvered location or through a continuous, concentric recess of the rotating mirror element (7) to the plane mirror (5) lying opposite the rear side of the mirror element (7). From there, the half-beams are reflected back to the rotating mirror element (7) and from the latter to two further plane mirrors (6a, 6b). Since the half-beams impinge perpendicularly on the plane mirrors (6a, 6b), they pass through - reflected by the plane mirrors (6a, 6b) - the described path in the reverse direction, recombine on the beam splitter (2) and are focused by the converging lens (9) on the detector (10). <IMAGE>
