Patent DE-3834245-A1 (DE)
Inventor: MOSER PETER ING
IPC: C21C5/46
Filed: 1988-10-07
Abstract: In metallurgical vessels, the production sequence, and especially the refining steps in crucible installations, is monitored by temperature measurement and sampling. This is done using a measuring lance (30) which carries a measuring cartridge (53) and is introduced into the melt through a passage orifice in the metallurgical vessel. In order to be able to introduce the measuring cartridge (53) without damage into the metallurgical vessel, when the passage orifice (6) is blocked by slag, it is proposed to guide the measuring lance (30) for axial displacement on the lance carriage (14) in a sheathing tube (18) and to provide the sheathing tube (18) with a cleaning tool (19) at the end which can be introduced into the metallurgical vessel. <IMAGE>

Title: Method for producing a ring of adjustable diameter and ring produced by this method
Inventor: SCHINDLER REINER DIPL ING
IPC: F16C35/073
Filed: 1988-11-24
Abstract: A ring 1 of adjustable diameter, having functional faces 2, 3 at its inside and outside diameter, consists of tapered rings 4, 5 which are arranged concentrically one inside the other and touch each other at mutually opposite tapered faces 6, 7. The tapered rings 4, 5 are displaced relative to one another, with application of an axial force on the end face 8, until their tapered faces 6, 7 lie completely one on the other and are held together in self-locking fashion. The inaccuracies and dimensional deviations of the functional faces 2, 3 which are caused thereby are eliminated by finishing the functional faces, e.g. by grinding, in which case the tapered rings are held together and no longer need to be dismounted after the finishing. Even after further displacement of the tapered rings relative to one another, the achieved dimensional tolerances of the functional faces are maintained. Such rings are used as bearing races in rolling bearings with adjustable radial play. <IMAGE>

Title: Safety fitting for side/bottom hung sash windows
Inventor: TONES CHARLES
IPC: E05D15/526
Filed: 1989-01-20
Abstract: The invention relates to a safety fitting for side/bottom hung sash windows, having a spring-prestressed slide bolt (20, 21) which comes into engagement with a stop (9) on a plate (7) of the drive gearing of the side-hinged/bottom-hinged system in order thus to prevent the displacement of the plate (7). A manually actuable unblocking part (13) for pulling back the slide bolt (20, 21) out of engagement with the stop (9) is provided in order to permit displacement of the plate (7). The fitting permits a selective control of the actuation of the system, for example the selection of the bottom-hinged mode and the prevention of the changeover into the side-hinged mode, until the slide bolt (20, 21) is brought out of engagement with the stop (9). The unblocking member (13) is mounted pivotably in a housing (12) which is fastened on the front reveal surface (5) of a window-sash part (1) by means of a screw (29). The unblocking member exhibits two fork arms (17) at one end, which are in engagement with a transverse pin (24) at the inner end of the slide bolt (20), and a press-button portion (16) at the other end, in order to pivot the unblocking member (13) by hand to pull back the slide bolt (20, 21) counter to a spring force. The safety fitting returns automatically into the initial position when the push-button portion (16) is released, in that the spring force ... the slide bolt (20, 21) into the operating position for the engagement with the stop (9) ...

Title: Device for generating an acoustic signal of variable loudness and device for carrying out the method
Inventor: LEPPER WERNER
IPC: G10H7/00
Filed: 1989-04-08
Abstract: In a method for generating an acoustic signal of variable loudness, in which an electric signal of constant frequency and amplitude and variable pulse width is generated, the electric signal is amplified electrically and the electric signal is converted into an acoustic signal in an electro-acoustic sound transducer, for the simple and cost-effective generation of acoustic signals of this type having virtually arbitrarily variable loudnesses and without the sound colour of the generated acoustic signal changing in the event of loudness changes, the frequency of the electrical signal is chosen to be higher than the upper limiting frequency of the sound transducer. In addition, a second electric signal of constant frequency, amplitude and pulse width is generated, the frequency of the second electric signal corresponding to the frequency of the acoustic signal and the second electric signal being superimposed on the first electric signal.
