Title: Tool for generating an axially directed force
IPC: B25B27/02
Filed: 1988-02-15
Granted: 1991-10-16
Abstract: The tool (1) is intended for generating an axially directed force on a rod in order to loosen or establish a press fit between the rod and a body, e.g. the connecting spigot, pressed into a tube end, of a joint connection. For this purpose, the tool (1) has a rod receptacle (24) with a clamping jaw (28) which can be pressed against the rod by a first working piston (20, 37), so that the tool (1) can be fixed to the rod surface without damage thereto. A second working piston (21), provided axially parallel to the rod receptacle, generates the desired axially directed force. The two pistons (20, 21) are moved one after the other by arranging in the hydraulic line (12-14) leading to the second piston (21), a pressure control valve (56) which opens only after the working movement of the first piston (20) has reached its end position. The hydraulic pressure is generated by a hand-actuated pump (36, 51, 53, 52) arranged in the shank (3, 4) of the tool (1). The hydraulic oil is stored in bellows enclosed in the handle (2) of the tool (1), into which bellows the return flow takes place after opening a pressure-release valve (66). <IMAGE>

Abstract: A speech amplifier circuit increases the maximum perceived loudness at the speaker (412) and reduces distortion at high volume levels without increasing the power consumed by the speech powder amplifier (410). When a low volume is selected by the volume control (414), the microcomputer (418) sets the step attenuator (406) at a correspondingly high attenuation level and the high-pass filter (408) is bypassed. As the volume control (414) is advanced and the speech power amplifier (410) is 12 dB into clipping, the microcomputer (418) activates the high-pass filter (408) and simultaneously steps the gain of the step attenuator (406) by 6 dB.

Abstract: Hitherto, sulphur compounds have been removed from hydrocarbons by adsorption on activated carbon, silicates and zeolites. The use of a zeolite containing zinc and manganese is also known. However, all the existing processes are unsuitable for removing traces of sulphur from hydrocarbons. The novel process is thus intended to allow a deep desulphurisation of hydrocarbons. The deep desulphurisation of hydrocarbons is achieved by adsorption of the sulphur compounds on zeolites which contain copper, silver or zinc or mixtures thereof. Deep desulphurisation of hydrocarbons.

IPC: G01N33/68

Granted: 1994-08-31
Abstract: A method is known for the determination of osteocalcin in human serum or plasma, in which a sample of the biological fluid containing the osteocalcin to be determined is incubated, together with a defined amount of an oligopeptide tracer, with a suitable anitbody which binds both the osteocalcin and the tracer. This method has proved to be susceptible to error in that the incubation conditions affected the measured levels, and the osteocalcin levels obtained were often too high. The recognition that the observed errors are attributable to a proteolytic breakdown of the oligopeptide tracer by constituents of the serum or plasma resulted in the technical teaching of the addition of one or more proteolysis inhibitors to the sample of human serum or plasma before or together with the addition of the oligopeptide tracer, specifically either a mixture of an endopeptidase inhibitor with an aminopeptidase inhibitor or, when an N-terminally protected oligopeptide tracer is used, only an endopeptidase inhibitor. Preferred inhibitors are amastatin and leupeptin.
