Title: Dowel with expansion sleeve
Inventor: FISCHER ARTUR PROF DR
IPC: F16B13/06
Filed: 1987-06-06
Abstract: In the case of the dowels which are provided for use in the tension zone of an anchor base, axial displacement of the expansion sleeve can occur when the bore widens as a result of crack formation, said displacement leading to considerable slippage, possibly even to failure of the anchoring. In order to permit or to improve follow-up expansion of the dowel, an annular widening, in which the resilient ring is inserted, is provided in the inner bore of the expansion sleeve, at its end remote from the expansion body. Via the resilient ring, said expansion-sleeve end can be widened to a diameter which extends beyond the external diameter of the dowel and, in the bore, can be compressed to the diameter thereof.

Title: Device for delivery rate control of a valve-controlled multipiston pump
Inventor: STUMPMEIER FRITZ DIPL ING
IPC: F04B1/28
Filed: 1987-12-01
Abstract: In multipiston pumps controlled by intake and discharge valves, devices for delivery rate control are used, in which there is provided, for each individual piston-cylinder unit, a longitudinally movable outlet valve which is arranged coaxially with respect to the piston and which permits return flow of pumped fluid to the intake chamber during the discharge stroke of the piston. Said outlet valve can be kept open adjustably over at least part of the piston stroke by means of a controlling element. In this arrangement, however, just before complete closure of the outlet valve there occurs a powerful hydrostatic surge at the valve element, which is all the more powerful, the larger the difference in the valve areas acted upon by the pressure medium. The result of these surges, particularly in those cases where the multipiston pump is used to deliver media having a low lubricating effect, is increased pump wear. The object of the invention is therefore to provide a delivery rate control device which reduces said wear and which, in combination, also permits hydrostatic relief of the piston in contrast with the known arrangements by means of a side channel (bypass). The outlet valve for discharging a portion of the liquid pumped in the delivery stroke, with its valve stem engages a cavity of the piston of a swash-plate pump, the piston having a valve seat for the outlet valve, and the cross-sectional area of the valve seat approximately ... the cross-sectional area of the valve stem ...

Patent DE-3802463-A1 (DE)
Title: Device for testing vessels
Inventor: RADEMACHER FRIEDRICH
IPC: B07C5/02
Filed: 1988-01-28
Abstract: Machines of this type are designed as rotary machines and have the corresponding inspection devices inside the circular path. It is necessary, especially in side-wall monitoring, that the bottles are transported free from any other devices and, on the other hand, they must have a corresponding separation from one another. This separation is generally larger than the smaller separation necessary for the other tests, so that the division of the bottle-receiving tray as a function of the side-wall monitoring device must be designed to be correspondingly large. It is now intended to provide a device in which the vessels involved can be brought into a large separation from one another with relatively simple means for the purposes of a specific inspection and, for the further tests, in which a smaller mutual separation is sufficient, can be guided through the machine essentially closer to one another. For this purpose, it is proposed that the bottles should be fed in a row formation having a fixed and/or known separation to a one-piece screw and brought in this to an increased mutual separation, conveyed with this separation to an inspection device and finally once more continuously formed, in a reverse-directed one-piece screw to the other separation necessary for further handling or further transport.

Title: Peak voltage meter
Inventor: SCHMIDT KONRAD DIPL ING
IPC: G01R19/04
Filed: 1988-05-31
Abstract: The peak voltage meter described contains a comparator (2) by means of which the voltage of a first storage capacitor (16) is compared with an input voltage (1). A pulse-shaper stage (7) controls a switch (8) in such a way, that the input voltage (1) is switched through to a charge capacitor (9) as soon as it is larger than the voltage on the first storage capacitor (16). At the same time, the first storage capacitor (16) is charged via a diode path (2) to the input voltage (1) and discharged again via a discharge resistor (17). In order that the highest voltage peak in a quasi noise-like signal can be measured sufficiently accurately with a peak voltage meter of this type, a controllable resistor is used as the discharge resistor (17). Furthermore, a control device (RE) is provided, which controls the discharge resistor (17) in such a way that the average frequency of the pulse train of the pulses appearing at the output of the pulse-shaper stage (7) assumes a desired value. <IMAGE>

Title: Method and arrangement for tightening braided packings
Inventor: SUOMINEN ILPO
IPC: F16J15/18
Filed: 1988-06-10
Abstract: The invention relates to a method and an arrangement for tightening braided packings in place in order to seal off a gap between a rotating machine component (1) and a non-rotating machine component (2). A sleeve-shaped tightening part (4) is arranged against packing rings (3) arranged in the gap and is subjected to an axial force. In the process, the pressure surface of the tightening part presses against the radial surface of the outermost packing ring (3) and tightens the packing rings axially in place. In order to make tightening reliable and simple, the axial force to which the tightening part (4) is to be subjected is produced by means of a hydraulic pressure. For this purpose, the pressure surface (6) of the tightening part (4) is a surface with a radially outward bevel. <IMAGE>

Title: Branched exhaust line of an internal combustion engine
Inventor: KRAUS NORBERT
IPC: F01N13/02
Filed: 1988-08-03
Abstract: A branched exhaust line of an internal combustion engine has two line branches, which lead to a starting catalytic converter or form a bypass to this respectively. The two line branches are formed from a manifold and an exhaust pipe in areas covering this with an intervening gap, which are arranged concentrically with one another. Under the effect of thermal expansion the two pipes move towards one another, thereby varying the opening cross sections of the inlet openings to the individual branches in accordance with the invention. The starting catalytic converter is thereby actuated only when the exhaust line is still cold; any overheating of the starting catalytic converter, rapidly reaching its operating temperature with a low mass flow, is thereby prevented owing to the automatic shut-off of the line branch leading to the starting catalytic converter.
