Patent DE-3022984-A1 (DE)
Inventor: STRIEGL GEORG DIPL ING
IPC: B23D77/04
Filed: 1980-06-20
Abstract: The device for adjusting a carbide blade for increasing the diameter in machine reamers has a pressure screw (123) for the carbide blade (87), a clamping shoe (103) which rests on the top side of the carbide blade, and a bore (117) for a clamping screw. Provided under the clamping shoe (103) is a backing piece (62), the underside of which can be displaced outwards on the bearing plane (18) for increasing the diameter and which in the mounting area is shallower that the carbide cutter (87) is deep. The clamping shoe (103) and the backing piece (62) are connected by a positive-locking feature (84, 107), the effective driving surfaces of which extend perpendicularly to the direction of the increase in diameter. The head is sufficiently rigid, since the forces appearing during the adjustment do not have to be taken into account in the design of the reversible carbide tip. The carbide tips can be narrower, as a result of which the recesses cutting into the head can be of flatter design.   <IMAGE>

Title: Electrical switch
Inventor: WUEST JOHANNES
IPC: H01M50/574
Filed: 1981-08-08
Abstract: In the case of an electrical switch having an electrically conductive ball (17) which is arranged in a housing (11) consisting of insulating material and via which two contacts (13, 14) are connected to one another, the ball (17) being pressed by a horizontal leaf spring (18) in the vertical direction against a bearing surface, this bearing surface is formed by two electrical conductors, which are used as contacts (13, 14) and are arranged with an air gap (16) between them. As soon as a shock is exerted on the vehicle which is equipped with the electrical [lacuna], for example as a result of a driving accident, the ball (17) moves against the shock direction as a result of the inertia of its mass, interrupting the connection, within the housing (11), between the contacts (13, 14). In this way, the vehicle electrical system is switched off immediately after the driving accident, so that cable fires or detonation of the fuel by the electrical system are avoided. <IMAGE>

Title: Fouling indicator for electrostatic filters
Inventor: HENGST BERND ING GRAD
IPC: G01N21/47
Filed: 1981-08-08
Abstract: Electronic fouling indicator (10) for electrostatic filters. With the aid of a scattered-light source (18) and via a photoresistor (17), a signal lamp (16) of a sweep oscillator (sweep generator, relaxation generator) (12) is triggered. The latter perceives a change, caused by fouling, in the reflection behaviour of the counterelectrodes (23) and converts it into flashing light pulses, the flashing frequency increasing with an increase in fouling. In order to compensate for the tolerances of the various electronic components, the photoresistor (17) is rotated about its longitudinal axis, and the angle (31) or the distance (29) of the signal lamp (16) and/or the angle (32) or the distance (30) of the photoresistor with respect to the measuring region are varied. The use of apertures (21) of various diameters or of adjustable apertures (22) is likewise envisaged. For the purpose of self-cleaning of the fouling indicator, there is assigned to a pull-out deposition electrode a broom (28) which can be pulled past the sweep generator. <IMAGE>

Title: Brake disc arrangement for disc brake systems of rail vehicles
Inventor: WIRTH XAVER DIPL ING DR
IPC: F16D65/12
Filed: 1981-08-18
Abstract: In a disc brake arrangement for disc brake systems of rail vehicles, the friction ring is held on a seat of the shaft by means of a clamping ring and of a hub ring, clamping elements in the form of bolts passing through the disc brake arrangement. In order to be able to remove the friction ring in both axial directions of the shaft, the hub ring can be released from the seat of the shaft; this applies equally to the clamping ring. In an advantageous embodiment, the hub ring is formed by a plurality of segments which can be removed individually from the seat of the shaft on removal of the clamping elements. The brake disc arrangement can also be used in an advantageous manner for multiple friction-ring arrangements, spacer tubes being provided between the clamping ring of one brake disc arrangement and the hub ring of the adjacent brake disc arrangement to maintain the axial spacing. The spacer tubes are penetrated over their entire length by clamping elements in the form of bolts, which likewise extend through the respectively adjacent brake disc arrangements and can be tightened from their ends. The hub rings can be in axial positive engagement with the seat of the shaft, for example by means of a thread, but they can also be connected to the seat by means of frictional engagement. In the latter case, an auxiliary ring is used which engages with a wedge-shaped extension between the seat of the shaft and the hub ring and brings about frictional engagement relative to the seat of the shaft by wedging. <IMAGE>
