Title: Position-measuring device
Inventor: KRAUS HEINZ
IPC: F16C19/52
Filed: 1984-10-20
Granted: 1986-05-07
Abstract: Such a position-measuring device for measuring the relative position of a shaft (33) with respect to a machine part (32) consists of a ball bearing having a freewheeling electrically conductive inner ring (23), a row of electrically conductive balls (22) in a cage (30) and of an electrically conductive outer ring (24). The outer ring (24) consists of two ring halves (24a, 24b) each having a shoulder bearing surface (25a, 25b) for the balls (22), which respectively have electrically conductive regions (25a1, 25b1) and electrically non-conductive regions (25a2, 25b2) which follow one another periodically and form two mutually offset divisions (24, 24b). An electrically conductive intermediate ring (26) having a bearing surface (26a) for the balls (22) is situated between the two ring halves (24a, 24b). The intermediate ring (26) is connected for the purpose of supplying power to a contact pin (27c), and the two ring halves (24a, 24b) are connected to one contact pin (27a, 27b) each for the purpose of dissipating power. In the event of rotation of the shaft (33), the cage (30) connected to the shaft (33) drives the balls (22), which scan the electrically conductive regions (25a1, 25b1) and the electrically non-conductive regions (25a2, 25b2) under mechanical contact. The balls (22) have a double function as scanning elements and as switching elements for directly obtaining pulsed scanning signals (Figure 3). <IMAGE>

Patent DE-3804181-C1 (DE)
Title: Measuring machine for measuring the spacing and/or the direction of chain studs (link pins) or teeth on endless roller chains or toothed (timing) belts
IPC: G01B5/16
Filed: 1988-02-11
Granted: 1988-11-24
Abstract: The roller chain to be measured is guided away over a plurality of deflecting rollers and a tension pulley in a releasing plane with a defined clamping force via a guide rail. Provided opposite the guide rail is a measuring head which moves to and fro and which is immersed with a multiple probe between the studs of the roller chain and measures the pitch of adjacent chain studs while the roller chain passes slowly by. In order to be able to undertake as accurate a calibration measurement as possible at the measuring head, there is arranged countersunk below the baseplate supporting the deflecting rollers and tension pulleys a calibration element which if required can be raised from the counterbore (countersink) into the releasing plane and into the region of the push rod. In a defined vertical position, the calibration element can be displaced by a fraction of a stud spacing parallel to the guide rail, a measurement of the spacing of the studs of the calibration element being undertaken. The calibration element is mounted on an oscillating (follower) lever suspended with the aid of a universal joint. The horizontal displacement movement is derived with a time offset by the same working cylinder which also effects the stroke movement of the oscillating lever. As a result, the calibration element guide and its drive are of a particularly low and simple construction, and are easy to maintain.
Patent DE-3820341-C1 (DE)
Title: Method and apparatus for filling receiving containers, in particular sacks, with pourable material in a specified quantity
IPC: B65B1/34
Filed: 1988-06-15
Granted: 1989-10-12
Abstract: An apparatus for filling receiving containers, in particular sacks, with pourable material in a specified quantity comprises a coarse-flow inlet 5 and a fine-flow inlet 6 which is separate from the latter, which inlets can in each case be closed by means of a flap. In this arrangement, a weighing container is assigned to the coarse-flow inlet 5. An additional weighing container 11 which is separate from the former is assigned to the fine-flow inlet. In this manner it is possible, even during the feeding and weighing of the fine-flow residual quantity, after previously emptying the weighing container 10, to feed a new coarse-flow quantity to the latter, as a result of which time is saved which can be used either for shortening the filling operation and/or for increasing the accuracy by extending the fine-flow filling time. <IMAGE>

Patent DE-4000184-C1 (DE)
Title: High pressure valve for pump - has choked-entry nozzle with seat mounted on braking ring having clamping surface
IPC: F04B53/10
Filed: 1990-01-05
Granted: 1991-01-10
Abstract: High pressure nozzle valve has choked entry, diffuser, constant valve clearance and wide spherical seat and can operate with low pressure loss at high pressures and piston speeds. To cushion the valve slap with retarded closure, the seat should be mounted on a braking ring (1) which has a generous damping surface and short braking stroke and is lifted when the valve opens by a spring (2) and by the valve entry (E) pressure acting on a free edge. When the valve closes the braking ring forces the brake space (B) fluid into the entry (E) as a result of the high clearance pressure in the seat. Fluid reaches the braking space when the ring lifts via a number of bores (C) in the seat and a ring channel (R). USE/ADVANTAGE - Pumps. Seat carried on braking ring which cushions valve slap with 70% less braking force.
