Inventor: KEMPE MANFRED DIPL ING
IPC: B23Q5/56
Filed: 1987-08-21
Abstract: A backlash-free drive for the infeed mechanism of a microtome, comprising a threaded spindle (1) mounted so as to be rotatable but axially non-shiftable, as well as two nut elements (2a, 2b) connected such that they are non-rotatable but can be shifted in an axial direction relative one another, said nut elements being spring-loaded against one another in an axial direction. Acceptable tolerances for the conicity of the threaded spindle are obtained by making use of at least one plain bearing (11,13;12,14) between the threaded spindle and nut element (2a), said nut element being connected to a specimen holder (16) via a gear. Fences (30,32;31,33) acting in the direction of spindle rotation protect the thread from deformation, as do two frictional clutches (24;25), which prevent excessive driving torques from having an effect and allow the user the option of operating the micrometer with manual feed (22) or an automatic feed device (26).

Patent DE-3737474-A1 (DE)
Inventor: VETTER RICHARD
IPC: F23N5/24
Filed: 1987-11-05
Abstract: The invention is based on devices for heating water, in particular a hot water boiler, with a combustion chamber which has an oil- operated or gas-operated burner, one or more heat exchangers and a suction draught blower which is to ensure a low pressure in the chambers flowed through by the smoke gases, specifically in such a manner that the burner is switched off when the prescribed low pressure is not present. In order to be able to carry out a reliable measurement of the internal pressure, the elements serving for determination of the pressure are, according to the invention, arranged in the region of the wall of the device, which serves for installation of the burner; an extensively turbulence-free measuring point is thus selected, which is also practically not exposed to dirtying and other influences. <IMAGE>

Patent DE-3804073-A1 (DE)
Title: Device comprising a transmitter, a receiver and a circuit arrangement for signal evaluation
Inventor: RUEFF MARTIN DIPL ING
IPC: G01S17/04
Filed: 1988-02-10
Abstract: The use of known devices of this type in large numbers, as is required, for example, in store control systems, necessitates a major wiring outlay because each individual device, for example in the form of a reflection light barrier, must be connected to a central controller via a dedicated cable. In addition, in the case of such a system of devices, it is impossible (at least at an economical cost) to interrogate a large number of information items. The novel device is intended to enable particularly economic wiring and the interrogation of a large number of information items, particularly when a large number of said devices are present or are being used. The device is equipped with at least one microprocessor or microcomputer (18) for information, control and regulation purposes. <IMAGE>

Patent DE-3828559-A1 (DE)
Title: Tangential propeller
Inventor: LANG RICHARD
IPC: B64C11/00
Filed: 1988-08-23
Abstract: In order to reduce the propeller noise which is produced especially in the case of aviation it is indicated for the underside of the profile of the propeller blade to be of concave construction in order that the incident air is deflected tangentially to the rear. The small air inlet edge of the relatively deep propeller profile reduces the drag of the profile. In addition to a major performance yield, a lower amount of noise development can essentially be expected. The tangential propeller can be used in all aircraft, land vehicles and water craft driven by an airscrew.

Patent DE-3832141-A1 (DE)
Title: Roller bearing guide for the rotating pistons in axial flow rotary engines
IPC: F01B3/04
Filed: 1988-09-22
Abstract: The pistons (8) rotating about the centre axis of the engine are moved up and down in the cylinders (3) in that their rollers (9) roll on the cam tracks (4) fixed to the engine housing (1), the line of symmetry (11) of which tracks is sinusoidal, as a result of which the lifting curve of the pistons (8) is also sinusoidal. So that the inside of the lifting cam (2) can guide the piston (8) and absorb the centrifugal forces with as little friction as possible, a running groove is radially recessed in its centre so deep that only one spherical surface of the balls (5) located therein protrudes. At one point of the running groove a perforation has been made for the introduction of tools and for the insertion of the balls (5) with the spacers (6), which perforation is then closed again by two small cover platelets (7). The stop face (10) of the pistons (8) bears on these only slightly protruding balls (5) thereby obtaining its circular guidance, whilst the centrifugal force of the pistons (8) is also absorbed by the balls (5). <IMAGE>

Title: Hazard luminaire
Inventor: WEINREICH WILHELM DIPL ING
IPC: E01F9/615
Filed: 1989-02-25
Abstract: A hazard luminaire for optically safeguarding sources of danger, for example roadworks and other sources of danger, which is to be mounted by means of a fastening part on a blocking element, for example the post of a distance marker, is improved and secured against detachment and hurling away of luminaire parts or the entire luminaire during a hard crash against the barrier, to the effect that the luminaire housing containing the optical part is designed with an integrally formed elastically resilient housing body, the fastening part is firmly attached to this housing body and that an accommodation opening, separate from the fastening part, is formed in the housing body in which the lamp carrier can be inserted and fastened, for example locked, from outside. The elastic resilience of the housing body can be designed to reach the limit of elastomeric deformability, that is to say up to a deformability which is usually inconceivable for technical construction parts. By arranging the accommodation opening for the lamp carrier separate from the fastening part of the hazard luminaire, the lamp carrier can be removed from the luminaire housing, serviced and reinserted without taking the luminaire off the respective locking element.
