Patent DE-3627135-A1 (DE)
Inventor: TASTO MANFRED
IPC: H04L7/033
Filed: 1986-08-09
Abstract: For synchronizing a data block in a receiver, there are transmitted consecutively and prior to the data block: a first bit sequence of alternating "0" and "1" levels for determining the bit clock and a second bit sequence for determining the block synchronization by correlation. In known methods of determining the bit clock, the phase range of the individual bits of the received digital signal is divided into sub-intervals and the phase position of the bit clock is determined on account of the number of edges in these sub-intervals. In order to avoid fading and phase jitter having a detrimental effect on the bit synchronism, more specifically when transmitting through radio transmission links, N-phase-shifted clocks having the same clock frequency are generated in the receiver by means of which the first bit sequence is sampled. The clock for which the number of sample-value changes of the first bit sequence is established as having a predeterminable minimum value during a predeterminable time-interval is utilized as the phase synchronous bit clock.

Title: Method for conditioning sewage sludge with calcium carbonate
Inventor: KREILINER WOLFGANG DIPL ING
IPC: C02F11/122
Filed: 1986-12-18
Abstract: In a regional recycling association, the calcium carbonate sludge arising in a slow decarbonisation of water is used as conditioning agent in sewage sludge dewatering. This ensures the disposal of the calcium carbonate sludge, and sludge dewatering at the water softening plant becomes superfluous. At the sewage treatment plant, the batching and addition of hydrated lime is dispensed with, for which the calcium carbonate sludge is a suitable replacement. The addition of calcium carbonate sludge is performed at a solids content of more than 30%. The addition of a flocculant, in particular iron(III) chloride is dispensed with. 2 to 5 kg of acrylate-based cationic polymers are added per tonne of solid as flocculant, which can be performed upstream of the high-pressure pump of a chamber filter press.
Patent DE-3700084-A1 (DE)
Inventor: SINNER ALFRED
IPC: F23N1/02
Filed: 1987-01-02
Abstract: Fuel-heated generators must work with a fuel/air ratio which is to be kept within narrow limits. With constant heating capacity, it is possible to add to a temporally constant quantity of fuel for this purpose a quantity of air, the flow rate of which can be kept constant by means of a blower. There is a requirement for generators, the heating capacity of which can be changed at least stepwise, despite use of such a simple device, for capacity adjustment. To increase the heating capacity stepwise, there is connected parallel to the main pipe (2) at least one secondary pipe (21), in which the same fuel/air mixture as in the main pipe is present, when the stipulated quantity of air is delivered in the main pipe. The preferred application of such devices is in generators for small central heating systems with water heating.

Patent DE-3708471-A1 (DE)
Inventor: ROLKER JUERGEN DR ING
IPC: G01M3/28
Filed: 1987-03-16
Abstract: To test the tightnesses of two valves arranged upstream respectively downstream of each other in a fluid line, the pressure conditions in the line portion between the two valves is measured with both valves being closed. Following a certain time after the closure of the two valves, the pressure in the line portion is measured to determine whether pressure is above or below a predetermined limit pressure to conclude whether the one or the other valve is tight. Following this determination, the passageway is opened across the valve taken to be tight and the line portion is then drained or filled. During a measuring time interval then following, a differential pressure sensing device measures whether and how often the pressure in the line portion reaches or passes the limit pressure. The valve not yet taken to be tight is judged tight if the limit pressure is reached or passed once and considered not to be tight if the limit pressure is not reached or passed or reached or passed more than once during the measuring time.

Title: Card-like hanging-up part and package provided therewith
Inventor: FREITAG WOLFGANG DIPL ING
IPC: B65D73/00
Filed: 1987-05-08
Abstract: Known hanging-up parts for or on packages consist of eyes which are punched out completely and whose upper edge section resting on a holder is relatively weak such that the eyes often tear out. Additionally, punching waste occurs when producing the eyes. To avoid these disadvantages, the hanging-up part proposed has at least one preformed eye (1) which can be pushed open in such a way that the edge section of the pushed-open preformed eye intended for supporting on a rod-shaped holder is joined to a material part (17) from the pushed-open inside area of the preformed eye (1), which material part acts as an edge reinforcement (Figure 3). Such hanging-up parts are used in blister packages, skin-packs and smaller cardboard packages. <IMAGE>

Patent DE-3724625-A1 (DE)
Inventor: MATTES RALF DR RER NAT
IPC: C12N9/38
Filed: 1987-07-24
Abstract: In an enzymatically inactive, immunologically active  beta -galactosidase mutein, at least one amino acid in the natural sequence in the region between amino acids 430 and 550 is replaced by another amino acid, and the enzymatic activity is not more than 1% of that of the native enzyme. For the genetic engineering preparation of a  beta -galactosidase mutein of this type, the DNA sequence in a plasmid coding for  beta -galactosidase is altered by site-directed mutagenesis in such a way that, after expression, at least one amino acid in the region between amino acids 430 and 550 of the protein is replaced by another one. An enzymatically inactive, immunologically active  beta -galactosidase mutein of this type is used in the immunological determination of serum proteins on the enzyme immunoassay (EIA) principle using the enzyme  beta -galactosidase as labelling enzyme to trap anti- beta -galactosidase antibodies or other binding proteins directed at  beta -GAL, any of which may falsify the assay result.

Title: Expansion dowel
Inventor: GSCHWEND PETER
IPC: F16B13/04
Filed: 1987-09-10
Abstract: The anchoring part (2) of the expansion dowel which comprises a load-application part (1) and an anchoring part (2) exhibits a plurality of members (3, 4, 5) which are in positively locking connection with one another via expansion cones and corresponding bores. For the setting procedure, first of all the member (5) which is foremost in the setting direction is fastened in a bore (7a), and subsequent relative displacement of the load-application part (1) with respect to the members (3, 4, 5) of the anchoring part (2) results in radial widening and thus in expansion of the individual members (3, 4, 5) of the anchoring part (2) in the bore (7a). Said widening becomes greater as the tensile loading on the expansion dowel increases, i.e. subsequent expansion takes place. <IMAGE>

Title: Apparatus for periodic control of liquid levels
Inventor: KUSEMANN UDO
IPC: C02F3/04
Filed: 1988-02-24
Abstract: For the biological degradation of pollutants in sewage treatment plants or for the purification of aquaria water, filter devices are used which have a high energy consumption. To decrease this energy consumption and to increase the biological purification efficiency, the invention operates with liquid levels which are periodically controllable by the action of gravity and buoyancy force with the aid of one or more floats and a vacuum produced in an outlet line. As a result of periodic changes in liquid level, a bacterial support material is passively supplied with oxygen necessary for an aerobic degradation, diverse air : water ratios advantageous for different bacterial genera being created in the bacterial support material. The floats are constructed in such a way that one of them forms a valve unit with an outlet orifice and closes the outlet orifice at a low liquid level. When the liquid level increases, the vacuum prevents an upthrust of the float. It releases the outlet orifice when the buoyancy of a second float acts on it or when the vacuum is released by a specially shaped overflow.
