Granted: 1992-01-29
Abstract: A hydraulic master cylinder (10) formed by telescopically fastening together a pair of cylinder housings (30, 34) to form a cylinder. A piston (64) in the cylinder is operative to transfer hydraulic fluid to a slave cylinder (15) connected to the master cylinder. The pressure or power stroke of the piston is effected by exerting a pull on the piston by a pull cable (24) attached to one side of the piston. A body (100), attached to one of the cylinder housings, provides a reservoir for hydraulic fluids. A cap (114) on the reservoir closes a fluid filling opening. Expansion bellows (130) in the reservoir accommodates changes in the fluid level in the reservoir as the piston is being reciprocated. The bellows are connected to the cap so as to be removed as a unit with the cap when the reservoir is being filled.

Title: Electronic multimeter
Inventor: HOCHREUTHER KARL
IPC: G01R1/36
Filed: 1989-09-30
Granted: 1994-06-01
Abstract: The protective circuits against overvoltages, provided in conventional multimeters, are not suitable for controlling high-energy voltage pulses above 1 kV such as can occur in low-voltage switchgear. The invention is intended to ensure that multimeters can also be used for measuring without danger in this area. A measuring adaptor (A) is proposed which contains a protective resistance (R1-R9) which considerably increases the resistance of the measuring line and which limits hazardous currents or voltages to a value which, in conjunction with the protective means (S, F, RS) of the input circuit (ES) is harmless to the operability of the multimeter (M). A multimeter equipped with the adaptor, a necessary, can be used not only in the laboratory area but also in low-voltage switchgear. <IMAGE>

Granted: 1994-12-21
Abstract: In a process for obtaining adjustment values for controlling a fuel tank ventilator valve connected to an internal combustion engine, the adjustment factor used is obtained from a calculating step for lambda control. The adjustment factor modifies a loading factor until such time as a quantity of regenerated fuel which does not lead to a deviation in the lambda target value is delivered through the fuel tank ventilator valve. The adjusted loading factor modifies pre-control values for the quantity of regenerated fuel to be supplied in the preceding operating mode. The process disclosed is characterized in that allowance is made for pressure, conditions prevailing in the fuel tank ventilator valve. The opening of the fuel tank ventilator pipe into the intake manifold of an internal combustion engine can therefore be located behind the throttle valve, where there is a high negative pressure which can nevertheless vary within wide limits. The process makes allowance for these fluctuations in the context of pre-control with overriden control, making it possible to operate reliably with high regenerated gas flow rates. The device disclosed comprises, in particular, means (33) for determining the flow rate which make allowance for the pressure conditions in the fuel tank ventilator valve, as well as means (31) for controlling the load which adapt a temporarily assumed loading factor to the actual loading factor.

Date Jun. 14, 1990.Using rollers having roller members which are adjacent on both sides to a center flexible longitudinal section capable of remaining in a respective bent position and have at each end an outer longitudinal section, previously perm or water-waved (pretreated) hair sections of a strand of hair are spirally rolled up, starting with the tips of the hair, first onto one outer longitudinal section, continuing then also onto the center longitudinal section, and finally the previously untreated hair section (hairline) is rolled substantially onto the other outer longitudinal section. The one outer longitudinal section is then bent approximately normally relative to the other outer longitudinal section such that the one outer longitudinal section and a portion of the center longitudinal section with the rolled-up previously treated hair section project substantially vertically upwardly from the head. Intensive-action perm or water-wave liquid is then applied only to the previously untreated hair section (hairline) rolled up substantially onto the other outer longitudinal section. The roller member of a roller (1) particularly suited for carrying out the process has a first longitudinal section (2) made of a substantially rigid material, which a fixing element (9, 10) is arranged on or engages. The first longitudinal section (2) is connected at one end to a second flexible longitudinal section (3) made of a flexible member (5) of a viscoelastic plastic, which flexible member (5) is arranged around a wire core (4).

Title: Arrangement at a hollow construction embedded in the ground for the transportation or storage of polluting liquids
IPC: E02D31/00
Filed: 1990-06-12
Granted: 1993-07-28
Abstract: In a hollow construction at least partly embedded in the ground or surrounded by the ground for the transportation or storage of polluting substances, such as, for example, in a drain channel, it is proposed to embed the wall of the hollow construction (2) in a sealing layer (3) of a non-setting mixture of mineral sealing materials, in particular clay materials such as, for example, montmorillonite, with the addition of mineral substances. In order to obtain as tight a storage of this layer as possible with a high solids content and small pore volume, it is furthermore proposed to pre-mix in the dry state the materials forming the sealing layer and to insert them as a dry mixture; the moisture required for the effectiveness of the mixture as a sealing layer is supplied after insertion. By such embedding of the hollow construction, it is possible, for example in sewage systems, to prevent polluting seepage water from being transported both longitudinally and transversely into the surrounding ground even at any damaged locations possibly occurring, which seepage water escapes through these damaged locations. <IMAGE>
