Filed: 1987-10-28
Abstract: Drive element (12) for print heads in ink printers with a piezoelectric transducer element (10) arranged on a chamber wall (15) of an ink chamber (14). In order to produce a high degree of stability of the mechanical connection between transducer element (10) and chamber wall (15), the transducer element (10) and the chamber wall (15) of the ink chamber (14) are connected to one another so as to engage one in the other in a positive fashion. For this purpose, a metal coil (16) which serves as internal electrode is soldered onto the piezoelectric transducer element. It acts as an anchoring component and thus ensures a positively engaging connection between the chamber wall and transducer element. <IMAGE>

Title: Clamp for twisted parallel wire bundles
Inventor: SCHLAICH JOERG DR ING
IPC: E01D19/16
Filed: 1987-11-06
Abstract: The clamp essentially comprises an inner shell and an outer shell. The inner shell (1) is adapted to the outer contour of the twisted parallel wire bundle (4) and may comprise a plurality of parts (8) which can move with respect to one another. The outer shell (2) encloses the inner shell and is made in two parts. The screws (6) fix the inner shell on the wire bundle and fix the outer shell on the inner shell. The outer shell bears the connection elements (5). By virtue of the ability of the inner shell to rotate with respect to the outer shell, the helical contour, resulting from the twisting of the parallel wire bundle, of the outer surface of said wire bundle does not influence the mounting accuracy in any way. <IMAGE>

Inventor: WAGNER GEORG
IPC: F41C23/00
Filed: 1988-10-11
Abstract: The stock of a sporting gun has in each case one cheek rest on the left and right sides for supporting the gun against the cheek of the person shooting. Both cheek rests are integrally formed on the stock, symmetrically with respect to a vertical centre axis. A cheekpiece which represents an extension of the cheek rest upwards is detachably and adjustably mounted on the top of the stock. The cheekpiece is constructed with a trapezoidal cross-section, the vertical centre axis of the stock forming the axis of symmetry of the trapezoid. A recess for the ball of the thumb, the ball of the hand and the index finger to rest in in each case is incorporated on each side of the stock, in the region of the pistol grip. As a result of the symmetrical arrangement of the devices for matching the stock to the anatomic characteristics of the person shooting, it becomes possible to use the same stock design for the left-handed and right-handed versions of the gun stock.

Title: Switching mechanism for low-voltage switching devices
Inventor: BECKER JOHANNES DIPL ING
IPC: H01H71/52
Filed: 1989-03-21
Abstract: In the case of low-voltage switching devices, a maximum switching capacity is achieved if the contacts are moved at high speed from a point shortly before reaching the contact-making position and with high force, independently of the connecting rate, by an operator, in order to make contact. The invention indicates a switching mechanism which interacts with a movement-dependent locking device consisting of a lug 17 and a rocker lever 21. This lever system operates in a dead-point position, in the extended (180@) or bent (0@C) position with a guide, by means of an oscillating support 15, or with a link guide through an elongated hole 31. The system is moved by a spring 19 into a self-holding position slightly above the dead point. The lever system can be moved from this position by a small tripping movement, with little force, into the other position beyond the dead point (geometrically locked position), from where the lever system automatically bends out further when a force is applied and enables the movement of a contact shaft 8. Such a switching mechanism can be used in all low-voltage switching devices in which rapid disconnection (immediate disconnection) is required. <IMAGE>
