Title: Residual monomer separation from vinyl! chloride (co)polymer - by polymer powder sepn. from drying air-stream and turbulent bed treatment
Inventor: HEINZE CHRISTOPH DIPL ING
IPC: B07B11/02
Filed: 1979-12-05
Abstract: In residual monomer sepn. from vinyl chloride polymers prepd. in aq. dispersion, most of the residual monomers are sepd. and part of the water is opt. dried in a warm air stream, following which gas and solid particles are sepd. and treated with gas in a turbulent bed. Novelty consists in effecting (a) polymer powder sepn. from the air-stream used in drying and (b) turbulent bed treatment together in the same separator compartment. The air quantity used for causing turbulence is 1/5 to 1/100 of the air quantity used for drying. Residual monomer content can be reduced to 10 ppm with low energy consumption.

Title: Liq. level monitoring based on relative transmissivity - using ultrasonic transmitter and receiver of varying sweeping frequency and measuring resonances
Inventor: SCHITTEK FRIEDRICH
IPC: G01F23/296
Filed: 1980-02-16
Abstract: The liq.level is monitored using an ultrasonic transmitter and receiver. Both are immersed in the liq. or not according to the liq.level. The method operates without the transmitted ultrasonic frequency being exactly fixed using an arrangement of transfer elements between the transducer and the measurement point. It is insensitive to varieties in the resonant frequencies of the transmitter and receiver. The frequency of the transmitter is swept within a defined frequency range (12) and the liq.level determined from the resonances occurring in the receiver. The receiver output is rectified or fed to a peak value detector determining the max. resonant voltage after each sweep period.

Title: Electron beam welding appts. - using electronic monitor circuit to keep beam on butt joint between workpieces
Inventor: PASTUSENKO JURIJ I
IPC: B23K15/02
Filed: 1980-09-05
Abstract: The electron beam passes through axial holes in a screen and a collector electrode(I) before reaching the workpiece. Sec. electrons (i.e. back-scattered electrons) are collected by electrode(I), which is connected to one input terminal of a comparator. The power supply which feeds the electron gun also supplies a signal to a second input terminal on the comparator.

Title: Tissues prepared for histological and similar investigations - using molecular sieve to adsorb residual water from hygroscopic or fat dissolving liquid before reuse
Inventor: WEINKAUF WILHELM PHILIPP
IPC: G01N1/31
Filed: 1980-12-20
Abstract: A process for removing water and/or grease from tissue specimens which are to be subjected to histological, histochemical, histo-autoradiographic and electron microscope investigations etc., and are to be embedded in sections of paraffin, plastics, methacrylate etc. consists of: subjecting the specimens first to a hygroscopic and/or grease-dissolving liquid with a boiling point lower than that of water, evaporating the resultant mixture of water and hygroscopic liquid, and condensing it to regenerate it, then recycling the condensed liquid for reuse. Before the condensed flow is reused, it passes through or over a molecular sieve-type material to adsorb any residues of water still contained in the condensed liquid. Pref., the molecular sieve material is heated to desorb it and regenerate it. Prefd. molecular sieve materials are synthetic zeolites (aluminium silicates of alkaline and/or alkaline earth metals). Preferred temperature for regenerating the sieve is 350-400 deg.C. Preferred pore diameter of the material is 2.5-4.5 Angstrom units. This process considerably increases the useful life of the liquid before it has to be completely replaced. For example, where acetone is used, its useful life is doubled.

Title: Remote control transmitter
Inventor: RUETTIGER ANTON
IPC: G08C23/04
Filed: 1981-03-11
Abstract: The remote control transmitter, shown in a block diagram in Figure 1, for transmitting IR remote control signals essentially consists of an input keypad (2), a microcomputer (1), a voltage supply circuit (31) with a battery (UB), a reference element (7) and an output stage (32). The voltage of the battery (UB) is 9 V. Since the microcomputer (1) only needs a voltage supply of 5 V, a simple external circuit is to be found which divides down the battery voltage. At the same time, the external circuit is to be used for reducing the load on the battery to a minimum when the keys are not operated. This is achieved by the microcomputer (1) continuously being connected to the positive terminal of the battery (UB) and the negative pole only being connected to the input keypad (2) when a key is operated. The supply voltage present at the microcomputer (1) is derived from a reference element (7) and stabilized. <IMAGE>

Title: Double steel strip piston rings for two-stroke engines
Inventor: FEY JOSEF
IPC: F16J9/04
Filed: 1981-03-20
Abstract: In piston rings for two-stroke engines there is the particular problem that, because of the inlet and exhaust ports of the cylinders, these rings must not wander, that is must not alter their position in relation to the circumference. They are secured against torsion by pins of the piston which are located in the area of the slots. As a result the same sections of the piston rings, resting with a varying load against the cylinder wall, constantly bear on the same cylinder wall making sections, which is unfavourable and the slots result in a deficient sealing. So that the piston rings can move freely in the slots under torsion and improved sealing is achieved, double steel strip piston rings (1) are used, the end sections (2) of which are deformed inwards so that in this area they either bear without any pressure on the cylinder wall or their ends are located in the middle of the piston ring groove. <IMAGE>

Title: Method for detecting the risk of icing on traffic routes, and ice warning sensor for carrying out this method
Inventor: THOMA ANDREAS DR
IPC: G01K3/10
Filed: 1981-05-13
Abstract: The invention relates to a method for detecting the risk of icing traffic routes, for example roads and bridges, and a corresponding ice warning sensor. In order to detect the risk of icing, the temperature of a detection surface is controlled and the instant at which ice forms on the detection surface is determined. In order to establish that there is icing, determination is made of whether with continuing cooling or heating of the detection surface there is at a measurement point on the detection surface a temperature variation in which during a specific interval the temperature of this measurement point remains constant or its tendency reverses. The temperature difference between the temperature of ice formation and the temperature of the environment is determined. The method can be used to forecast when the formation of ice will set in as the ambient temperature continues to fall. It can be determined, in addition, whether and to what extent it is necessary to use thawing means to prevent the formation of ice. An ice warning sensor for carrying out this method has a detection surface which can be heated and cooled, and which is preferably heated or cooled by the use of Peltier elements. Two temperature sensors are present, of which one determines the temperature of the detection surface, while the other determines the temperature of the environment. By combining a plurality of ice warning sensors at points which are particularly at risk, it is possible to create a system which is connected to a central monitoring device.
