Patent DE-3243973-A1 (DE)
Title: Orbital sander
Inventor: FRERS GERD DIPL ING
IPC: B24B23/04
Filed: 1982-11-27
Abstract: A driver (8) is slipped in a rotationally locked manner onto the motor shaft (6) of an electric drive motor (1) of a portable orbital sander. Located in its slot (10) open at the margin is a ball (11) which can move in the radial direction in this slot. When the driver (8) is rotating, the ball (11) circulates in the rolling path (10) of an extension (13) of the sanding plate (14) of the orbital sander in accordance with the angular velocity of the motor shaft (6). This results in a centrifugal force which deflects the sanding plate (14) radially relative to the motor shaft (6), and in fact under flexible deformation of the flexible intermediate elements (21) inserted between the sander housing and the sanding plate (14). On account of the revolving centrifugal force, the sanding plate (14) performs a circular movement relative to the motor shaft (6), which circular movement is utilised for sanding. <IMAGE>

Patent DE-3305699-A1 (DE)
Title: Oxygen saturation sensor
Inventor: WEBER DAVID C
IPC: G01N27/416
Filed: 1983-02-18
Abstract: An oxygen sensor based on a dry packing for a device for measuring the oxygen saturation or the varying oxidising and reducing gas ambient by means of the oxygen partial pressure in the exhaust gas from combustion installations, for example furnaces, internal combustion engines etc. A fairly high bias (approximately 10 V DC) at the cathode a blocking of the anode, thereby producing a forbidden energy range in which the exhaust gas passes through the stochiometric equilibrium (rich/lean; lean/rich). This provides a readily usable sensor output signal for switching, for example, the carburettor of internal combustion engines, and the entire measurement or the control resulting therefrom can take place rapidly, reliably and precisely without external oxygen reference gas and the equipment and process difficulties associated therewith. <IMAGE>

Patent DE-3313148-A1 (DE)
Title: Device and method for displaying the overshooting and undershooting of a prescribed limiting temperature
Inventor: STEPHAN EBERHART PROF DR
IPC: G01K11/06
Filed: 1983-04-12
Abstract: The invention relates to a device and method for displaying the overshooting and undershooting of a prescribed limiting temperature. The object of the invention is to provide a device, which can be produced inexpensively and operates in an extremely simple way, for indicating the overshooting and undershooting of a prescribed limiting temperature which can be read off without difficulty by the user. The invention achieves this object due to the fact that the device consists of a fusible material, whose melting point is equal or close to the limiting temperature, and an absorbing material as indicator, and that the fusible material is mounted at or near the absorbing material in a compact form and in the solid state at a position which does not cover the view onto the absorbing material. In the case of the indication of undershooting of a prescribed limiting temperature, a material in the gaseous state is brought as indicator into the vicinity of an absorbing material in such a way that after transition into the liquid state said first material is absorbed by the latter material and this becomes detectable.

Title: Device for measuring the wall thickness of a tubular part
Inventor: MONNO ASAO
IPC: B21B17/14
Filed: 1983-07-28
Abstract: A device for measuring the wall thickness of a tubular part has a radiation source consisting of a plurality of radiation sources arranged in a line. The radiation passes through a collimator, in order to form parallel beams which pass at right angles through a tubular part to a radiation receiver. The length of the radiation source and of the radiation receiver are in each case greater than the diameter of the part being measured, so that the radiation passes through a complete cross-section of this part, in order to be able to determine the wall thickness of the tubular part from the magnitude of the attenuation of the radiation which is captured by the receiver.

Patent DE-3336182-A1 (DE)
Title: Embossing tool
Inventor: KULL HERMANN ING GRAD
IPC: B44B5/00
Filed: 1983-10-05
Abstract: An embossing tool has a housing (1) and a ram (6) mounted so as to be axially displaceable therein. The ram (6) carries out a reciprocating lifting movement, driven by a motor, and, if required, a rotary movement at the same time. The lifting movement of the ram (6) is derived from a rotating drive element via a cam drive. In particular, an end-side cam oriented transversely to the lifting direction of the ram (6) can be picked off by an arrangement of rollers (25). The drive connection to a motor is produced via an elastic coupling or flexible shaft. The ram (6) operates at about 150 embossing strikes per second. <IMAGE>

Abstract: The invention relates to an articulated vehicle which consists of several links (1, 2, 3, 3a) which are arranged one behind the other and are connected to one another in such a way that they can bend relative to one another or can be displaced relative to one another. These links are provided with sliding surfaces (15) on their underside and possibly also on their side walls, with which sliding surfaces (15) the links can be put on a firm base, the sliding surfaces being made of a slidable material which has as low a coefficient of friction as possible on the material of the firm base. The base can be formed by a channel in which the vehicle is driven and guided by potential energy. The articulated vehicle is intended for amusement parks in which it performs a downhill run in a guiding channel. The vehicle can at the same time be amphibious. <IMAGE>

Title: Changeover device between a network and load circuits
IPC: H02J3/14
Filed: 1983-10-26
Abstract: A changeover device between a network (R-Y-B-N) and load circuits (a...c) is intended to be designed such that the individual circuits (a...) can be allocated with a free selection as required to external interrupter control elements (13) without any costly installation modification work, so as to take into account especially time switches (14; 15) having time-switching programs which can be set differently, cut-off relays (16) of overload interlock circuits, or manually operable OFF switches (17). To this end, an interrupter switch (18) is arranged in each of the load circuits (a...) which can be cut off, which interrupter switch (18) can optionally be driven from one of the external control elements (13), via a changeover switch (19). Each of these load interrupter switches (18) can preferably also be controlled from a load current monitor (21), which is located in the corresponding phase (R, Y or B respectively), when the total phase current (J) exceeds a predetermined maximum phase current value (I) at which a slowly responding network release device (24) would cut off all the phases (R, Y and B). In this case, it is expediently provided for the load circuits (a...) to be cut off in the respective phase (R, Y or B) by the load current monitor (21) in the sequence of increasing operational readiness priorities, until the remaining total current (J) no longer exceeds the predetermined maximum current value (I); and, after a specific waiting time interval, [lacuna] in the reversed ...

Title: Hinge having removal prevention
Inventor: KOENEN KARL-HEINZ
IPC: E05D7/10
Filed: 1984-04-17
Abstract: A hinge (2) having removal prevention for the tailboard of a commercial vehicle possesses a first part (4) fastened to the tail- board and a second part (7) to be fastened to the chassis. The first part (4) consists of a baseplate (16), of a web (15) and of coaxial pivot pins (5 and 6) formed on the web (15). A flange (13) projects beyond part of the circumference of the pivot pins (5, 6), engages into a recess (14) of the second part (7) and secures the first part (4) against axial displacement in a specific pivot-angle range. The second part (7) possesses, for the pivot pin (5), a bore (9) located in a block (8) and, for receiving the second pivot pin (6), a shell (10) open upwards. A projection (27) of the second part (7) prevents the axial displacement of the first part (4) in a lower pivoting range of the latter. The shell (10) defines a vertical slot (29) for the second pivot pin (6) and possesses a recess (31) complementary to the second pivot pin (6). With the tailboard swung up, a screw (23) passing through the baseplate (16) is at a distance (25) from the block (8) which prevents the possibility of an unauthorised unscrewing of the screw (23). <IMAGE>
