Abstract: A component pairing comprises a first component with a first component toothing and comprises a second component with a second component toothing which is in engagement with the first component toothing in order to be able to transmit a drive force in a drive direction via the component toothings. The first component is also assigned a first anti-rattle toothing. An anti-rattle component is fastened to the second component, which anti-rattle component has a second anti-rattle toothing which is in engagement with the first anti-rattle toothing. The anti-rattle component is mounted so as to be displaceable relative to the second component in the drive direction. The second component and the anti-rattle component are assigned in each case one friction section. The friction sections are in frictional engagement with one another.

Abstract: The present invention concerns a method of preparing a cellulose carbamate solution by dissolving cellulose carbamate in sodium hydroxide solution at temperatures of <10° C., wherein an 8% to 15% cellulose carbamate solution with a sodium hydroxide concentration of 7% to 12% is prepared in a first step, and then the solution is adjusted to a sodium hydroxide concentration of <9% by diluting with dilute sodium hydroxide solution and/or water in a second step, with the provision that the weight ratio of cellulose carbamate to sodium hydroxide in both steps is >1.

Abstract: An integrated circuit wherein no disturbances due to spikes occur is provided for converting a gap-infested clock into a gap-free clock. In a phase-locked loop the frequency of a read-in clock is supplied to a phase discriminator via a frequency divider and the frequency of a read-out clock is supplied to the phase discriminator via another frequency divider. A succession of clocks shifted in phase relative to one another is provided by a generator from an auxiliary frequency of a crystal oscillator which feeds an auxiliary successor sequence clock generator which provides a plurality of successor auxiliary clocks. Which of these clocks provides the read-out clock after a division in a frequency divider is defined by a switching frequency output by a frequency divider which is controlled by the phase discriminator.

Abstract: A phase regulating circuit which converts a slot clock signal at an input into a slot-free clock signal with a low jitter at an output, comprises a phase discriminator, two identical frequency dividers and a regulating and oscillator circuit. The regulating and oscillator circuit comprises a quartz crystal oscillator which supplies an auxiliary frequency, and an adding counter which generates a further signal with a further frequency. One control input of the adding counter is connected for this purpose to the output of the phase discriminator, while a second input of the adding counter is connected to the output of the quartz crystal oscillator. The auxiliary frequency and the further frequency are each connected to an input of an EXCLUSIVE OR gate by which they are added by regular polarity reversal. From this added frequency, a frequency divider obtains the frequency of the clock signal.

Abstract: A rotary piston pump includes a casing and partitions within the casing defining an expansion chamber and with a gear and bearing chamber on one side of the expansion chamber and a bearing chamber on the other side. The partitions between the expansion chamber and the bearing and gear and bearing chambers are provided with passages for receiving shafts serving for the transmission of the rotary movement from gears to the pistons of the pumps. The passages between the chambers are provided with split seals which are composed of two parts separated by a pressure equalization chamber.

Abstract: Antibodies against the M subunit of CK isoenzymes having a molecular weight between about 130,000 and 210,000, and inhibiting the enzymatic activity of the M subunit, optionally also in the presence of CK substrates, without inactivating the enzymatic activity of the B subunit of any CK-MB which may be present, are described. A process for the production of these antibodies comprises inoculating animals with activated CK-MM and recovering the antibodies in a conventional manner.

Abstract: A process for determination of CK-MB activity in a sample of a body fluid comprising the steps of incubating the sample, optionally in the presence of CK substrates, with antibodies which inhibit enzymatic activity of the M subunit in CK isoenzymes MM and MB without inactivating enzymatic activity of the B subunit in any CK-MB which may be present and determining the activity of the CK B subunit in the resultant sample.

Abstract: Isoenzyme patterns of an enzyme in biological fluids, extracts, and/or excretions are quantitatively determined by precipitating at least 90% of an isoenzyme antigen with a corresponding heterologous antiserum and comparing the remaining enzyme activity with the total activity with the use of a conventional agent for enzyme activity determination.

Abstract: Glucose is rapidly ad quantitatively determined with an analytical agent containing glucose dehydrogenase having an activity of at least 2 .mu./mg and NADH.sub.2 oxidase activity less than 0.1%, a pyridine coenzyme, a buffer and mutarotase to increase spontaneous mutarotation of alpha-glucose to beta-glucose. There may be optionally present inhibitors for reduced pyridine coenzyme oxidases and a thermal stabilizing amount of alkali metal chloride.
