Title: Drilling apparatus for earth bores
Inventor: MAGER WERNER
IPC: E21B3/04
Filed: 1981-07-01
Abstract: The drilling apparatus for earth bores has a feed device, a rotary drive carried by the latter, and a rope-actuated drill stem formed from telescopic kelly bars. The rotary drive acts on the outermost kelly bar of the drill stem, and the innermost kelly bar of the drill stem carries the drilling tool. Mechanical locks are provided between the kelly bars. To obtain automatic locking and unlocking of the kelly bars, a stop (10, 11, 12) limiting the entry movement is arranged in the rotary drive (2) and in the respective bottom end of each kelly bar (3, 4) with the exception of the innermost kelly bar (5). A support (13, 14, 15) arranged at the top end of the kelly bar following in the entry direction bears in each case against the stop (10, 11, 12). Locking members (16, 17, 18) spring-loaded in the locking direction are arranged above the stop (10, 11, 12) in the rotary drive (2) as well as in the bottom ends of the kelly bars (3, 4) with the exception of the innermost kelly bar (5). In the locking position, these locking members (16, 17, 18) overlap the top end face of the next kelly bar. The locking members (16, 17, 18) and the end faces of the next kelly bar but one in each case in the extension direction have bevelled sliding surfaces (16a, 17a, 18a and 20, 21, 22 resp.) for unlocking the locking members during withdrawal of the drill stem, and arranged in the top end of the innermost kelly bar (5) is a coaxial unlocking body (23) for the locking members (18) of the next outer kelly bar (4). The unlocking body (23) is longitudinally movable, in such a way as to be limited by a stop, by the rope (7) carrying the drill stem and has bevelled unlocking sliding surfaces (24). The locking members (16, 17, 18) can be designed as radially displaceable pins whose ends directed towards the centre of the drill stem are of tapered design in order to form the sliding surfaces (16a, 17a, 18a). <IMAGE>

Patent DE-3141314-A1 (DE)
Title: Process and casting mould for producing plastic structures
IPC: G10K11/24
Filed: 1981-10-17
Abstract: The invention relates to a process for producing individual plastic structures, preferably for otoplasty, from rubber, in particular silicone rubber, with the aid of moulds of plaster, embedding compounds or the like, using an impression from an impression compound. The process is made up of several steps, the impression of the concha being embedded in one half of a cuvette filled with moulding compound, the impression being removed from the negative mould thus produced after adequate hardening of the moulding compound. A casting compound, temperature-dependent in terms of its viscosity, is poured in the heated, liquid state into the negative mould and is kept in the negative mould until a desired wall thickness is obtained by cooling of the casting compound. After achieving the desired wall thickness, the still pourable casting compound is removed from the negative mould and, after trimming the contour of the hardened casting compound protruding from the negative mould, the positive casting mould is produced by applying a moulding compound to the hardened casting compound. After hardening of the moulding compound, the positive mould thus produced is separated, the casting compound situated between the positive mould and negative mould is removed and the rubber for the plastic structure to be produced is introduced into the negative mould, closed off by the positive mould and brought together under a press, which exerts a predetermined pressure on the positive mould and negative mould, and is fully cured. The casting mould comprises a positive mould and a negative mould with an internal, virtually equal distance between positive mould and negative mould, which corresponds to the thickness of the plastic structure to be produced.

Title: Device for securing printed circuit boards on the wire grid of a soldering frame during wave soldering
Inventor: LEOPOLD GUSTAV
IPC: B23K3/08
Filed: 1981-11-30
Abstract: Flexible clips (6) are used to secure assembled printed circuit boards (5) on the grid wires (4) of a soldering frame during wave soldering. These clips (6) have actuating elements axially movable in a housing against the pressure of a spring. The top end piece of the actuating elements is designed as a finger push-button and their bottom end piece, projecting from the end face (23) of the housing end (8), is provided with a hook-shaped bent-up portion (12) which in the working position encloses a grid wire (4) from below, while the end face (23) is partly supported on the top side of the printed circuit board (5) and presses the latter against an adjacent grid wire (4) or against spacers (22) attached to it. The clips (6), attached at several points of the edge of the printed circuit board, prevent bending of the printed circuit boards during the wave soldering and the cold soldering spots caused by this. The device is preferably used in the wave soldering of large and/or irregularly shaped flat printed circuit boards, in particular multi-layer printed circuit boards. <IMAGE>
Patent DE-3152731-A1 (DE)
Title: Contour measuring instrument
Inventor: IIDA JYNICHI
IPC: G01B7/28
Filed: 1981-02-14
Abstract: A contour measuring instrument conventionally has at the end of an arm (6) mounted rotatably on an arm support (13) a stylus (22) which is brought into contact with the outer surface of an object (23) to be measured, while the arm support is moved parallel to the contour surface to be measured. Owing to the rotary movement of the stylus (22) about the joint on which the arm (6) is pivoted, the stylus executes a movement in the shape of a circular arc, so that it is moved not only in the vertical direction, but also in the conveying direction of the arm support. These movements in the conveying direction of the arm support can inject errors into the measurement, especially if there are substantial unevennesses of the outer surface of the object to be measured attended by corresponding deflections of the stylus. According to the invention, these "circular arc errors" are corrected by, on the one hand, constructing the pivot joint of the arm (6) to be movable in the conveying direction of the arm support (13) and, on the other hand, by providing a connecting member (78) one end of which is pivotably mounted by the arm (6), and the other end of which is pivotably mounted by the fixed arm support. The component of the stylus movement in the conveying direction of the arm support is thus compensated by displacement of the arm pivot joint. <IMAGE>

Patent DE-3233410-A1 (DE)
Title: Illumination for medical purposes
Inventor: SCHOELLY WERNER
IPC: A61B1/07
Filed: 1982-09-09
Abstract: An illumination (1) for medical purposes exhibits a light source (2) and a plastic optical waveguide (3) connected thereto. By using such a plastic optical waveguide (3), the possibility is given to modify the latter in accordance with the respective requirements. For example, it can be cut by scissors or a knife or the like, it can be bent into a desired direction by heat action on areas; in addition, it can be fused to a lens by means of a flame so that entry and exit losses are reduced, and the exit angle can also be reduced for a higher light concentration. Finally, one or more interruptions of the reflecting jacket layer can be made laterally at the optical waveguide, by means of which a light exit is also possible, for example at 90 DEG  to the optical axis. Nevertheless, light still emerges at the same time at the outlet end so that combined illuminations are also possible under difficult conditions. To hold the optical waveguide end, holders can be provided at the corresponding instruments so that full illumination can be produced in each case at the point just being treated. A cross sectional deformation of the plastic optical waveguide under heat effect is also possible. <IMAGE>
