IPC: G01N25/18
Filed: 1983-06-03
Abstract: There is obtained a continuous rapidly responding and controllable measurement of the quenching intensity of quenching baths. A test body is inserted into the bath and a controlled heating is applied to a portion of the surface of the test body raising the temperature of that portion of the test body surface to a constant temperature of 50 DEG  to 700 DEG  C., especially 150 DEG  to 400 DEG  C. higher than the temperature of the bath. The heat energy required to maintain this temperature constant is used as a measure of the quenching intensity of the bath.

Patent DE-3331040-A1 (DE)
Title: Switching rail for model railways
Inventor: GRUHN WOLFGANG
IPC: A63H19/32
Filed: 1983-08-23
Abstract: This is an application for a patent for a switching rail in combination with one or two relays. The switching rail serves for automatically reversing the polarity of a track system for a dc model railway if reversible figures are used which permit tracks to be travelled over in the opposite direction. At the same time, it is possible to set points automatically. The reversal of polarity of the track system necessary for the unimpeded continued passage of a train (accompanied by setting of points) takes place here by the switching rail with its contact rail elements being travelled over as a result of which relays for switching over are actuated. As a result of the double function of the switching rails - track polarity reversal and setting of points - it is possible to travel through complicated track configurations without manual interventions. <IMAGE>

Title: Method and device for monitoring the prestress of a bolted connection
Inventor: BEUMER BERNHARD DIPL ING
IPC: B65G43/02
Filed: 1983-12-23
Abstract: The invention relates to a method as well as a device for monitoring a given prestress of a bolted connection of a working appliance, in particular a bolted connection for connecting two belt ends at the connecting point of a conveying belt, made endless by means of a so-called clamping connection, of a belt-type bucket elevator, a signal being produced if the prestress falls below a predetermined limit value of the prestress to be monitored, which signal draws the attention of the operating personnel to the fact that the prestress has fallen below this limit or triggers a switching operation which prevents further operation of the working appliance or reduces the output of the working appliance to a value at which the actual value of the prestress is still adequate for a proper mode of operation (Fig. 3). <IMAGE>

Title: Locking structure for hammers of ball-calibre weapons of tilting design
Inventor: HYYTINEN TIMO
IPC: F41A3/58
Filed: 1984-05-23
Abstract: A locking structure for hammers of ball-calibre weapons of tilting design, by means of which a rearward-directed movement of the firing bolt (15, 18), caused by the pressures of the charge gases, and penetration, caused thereby, of detonator material from the side of the breech base (23) into the hole (19) of the firing bolt (15, 18) is prevented when its weapon is fired. The locking structure consists of a supporting fork (30), which is fitted to the ram (12) of the breech (10) of the weapon and is designed in such a manner that it is moved into the locking position (30') by the force of a spring (13) when the weapon is fired. In this locking position, the supporting part of the supporting fork (30) rests against the hammer and locks the hammer (24a, 24b) in the forward position and hence prevents the tip (18) of the firing bolt (15) being displaced backwards by the force of the charge gases. When the weapon is levelled, the supporting fork (30) pivots, thanks to the close-tolerance fit (29) between the ram (12) of the breech (10) and the supporting fork (30), into the upper position in such a manner that the hammer or hammers (24a, 24b) of the firing bolt can be cocked without hindrance.

Title: Sowing appliance
Inventor: LINK ALFRED ING GRAD
IPC: A01C15/00
Filed: 1984-10-25
Abstract: A sowing appliance has a supporting frame (5) which is held by two parallelogram links (3, 4) and the ground clearance of which is fixed by a supporting wheel (10) mounted on a rocker (12). The rocker (12) is vertically adjustable by means of a first adjusting device (15). A two-armed lever (17) is mounted pivotably on the rocker (12) and carries an implement (20). The second lever arm (21) of the two-armed lever (17) has a long hole (22), through which a screw (23) is guided with play. This screw (23) is fastened to a strut connected to the supporting frame (5), so as to be displaceable transversely to the direction of the long hole (22) in the second lever arm (21) by means of a second adjusting device (27), so that the ground clearance of the implement (20) can be adjusted. The lever ratios are selected so that, when a first adjusting device (15) by which the furrowed depths can be varied is actuated, the height of the clod clearer (20) above the ground (9) does not change.   <IMAGE>

Title: Device for fastening tools to a robot hand
Inventor: WINDEL FRIEDRICH DIPL ING
IPC: B25J15/04
Filed: 1985-04-19
Abstract: The robot hand 6 is provided with a bolt which engages in a clamping opening of a device which essentially consists of two locking slides which are under spring pressure. The robot hand moves in the direction of arrow 25 during its engagement action. After the centring action, the robot hand moves in the direction of the arrow 27 and lifts out the device, which was first of all held in the opening member 4, together with the tool 7 towards the top. As a result, the legs 8 of the opening member release the locking slides, which tightly clamp the tool 7 to the robot hand. A special drive for fastening the tool to the robot hand is thereby avoided. <IMAGE>
