Patent DE-2609869-A1 (DE)
Title: Measurement of bed loading in adsorption beds - using variation in dielectric constant to generate signal from electrical condenser
Inventor: DANNHAEUSER KURT DIPL CHEM DR
IPC: B01J20/34
Filed: 1976-03-10
Abstract: Measurement of the loading and break point of adsorption beds is done by using the adsorbent as the dielectric filler between the plates of an electrical condenser through which the gas or vapour is free to flow. As this is adsorbed onto the adsorbent its dielectric constant changes with a corresponding change in the capacitance. This is then used as a measure of the loading on the adsorbent. One or more of these measurement condensers can be installed inside or outside an adsorption bed. The condenser can extend the length of the bed. An a.c. source is supplied via a bridge so that variations in the bridge output can be fed to an amplifier and then rectified to give a d.c. signal. Used to measure the degree of adsorption and optimise the process. Breakpoint is usually determined by analytical checks on the gas stream. These require trained personnel, are time consuming and therefore expensive. Direct measurement of bed loading is either not feasible or is specific to a partic. cpd.

Title: Heating radiator made from convoluted plastics pipe - has pipe forming enclosing frame and middle region for heat exchange
Inventor: FUCHS HARTMUT
IPC: F28F21/06
Filed: 1976-03-16
Abstract: The plate shaped heating radiator is made from plastics and has a channel for the flow of a liquid heat carrier. The arrangement eliminates weak points completely in the plate shaped heating radiators caused by the pipe penetrations. The radiator is still stiff enough to resist torsion caused by externally applied forces. It also ensures sufficiently good heat transmission to the room air. The flow channel is formed by a single pipe whose both ends (1, 2) are connected to the heating liquid supply and return elements. One or both end regions of the radiator tube forms an externally enclosing heating element boundary (3). The middle region (4) of the pipe forms heat exchange surface within the enclosure with convoluted shape. The end region of the pipe forming the radiator boundary (3) has larger diameter than the middle region (4) of the pipe.

Title: Gas purification filter plant - with gas passing through solid particles flowing countercurrently, in chamber with rakes ensuring uniform flow
Inventor: SGASLIK FRIEDRICH
IPC: B01D46/34
Filed: 1976-04-13
Abstract: A plant for purifying a gas, contg. dust consists of a cylindrical body with pref. several annular filter chambers parallel to one another and one above another. The body has an upper entry and a lower outlet for the solid particles and a lower inlet and upper outlet for the gas. The solid particles flow through ducts in the outer part of the body into the annular chambers and are discharged over bases which slope towards the middle of the chamber, on to horizontal surfaces. Scrapers attached to a vertical shaft pass over the cone of solids formed and remove a predetermined quantity which falls into pockets in a sleeve, and from the sleeve into the bottom of the body where the solids are discharged. The rate of rotation of the shaft determines the flow and discharge of the solids. The gas passes upwards and sideways through the moving bed of solids to a collector from which it goes to the outlet. The plant is partic. useful for removing dust from e.g. air or from residual gas during the mfr. of cement. It ensures a more regular flow of filter medium than in existing plants. The flow can be adapted to the needs of the partic. sepn. being carried out so as to give optimum filtration.

Title: Telephone handset tilting support member - firmly holds handset to free operator's hands whilst telephoning and taking notes
Inventor: ZIZKA LADISLAV
IPC: H04M1/04
Filed: 1977-03-18
Abstract: It often happens that during a telephone call it becomes necessary to make a note of something. In order to free his hands, the user of the telephone handset tilts his head and slides it under his ear. Openable supports solve this problem only partially, since they do not grip the handset sufficiently firmly. The problem can be solved with a tilting support member which is fitted on the handset. As the need arises, this can be tilted or lowered and the operators hand remains completely free whilst the telephoning takes place.

Title: Open=end spinner yarn splicing - rotates the broken yarn to ensure that the opened-up end is symmetrical
Inventor: STAHLECKER FRITZ
IPC: D01H4/50
Filed: 1977-03-23
Abstract: The mechanism to splice a broken yarn in an open-end spinning unit, has a system to twist the yarn round its longitudinal axis while the end is opened out as it is reversed into the spinning chamber. The clamping sections of the yarn reversing mechanism have a rotary drive which turns against the direction in which the yarn was spun. The clamping section nearest to the yarn winding station is rotated at a slower speed than the other section. A rotating abrasive cylinder is used to open out the broken yarn end, rotating on an axis across the axis of the yarn being spliced, with grooves running round its circumference, in a spiral. The position of the abrasive cylinder can be adjusted through a swing arm mounting to place it at the end of the broken yarn in a reciprocating motion between the clamping sections. The system ensures that the fringed end of the broken yarn remains symmetrical as it is returned into the spinning chamber to be spliced with the end of the newly-spun yarn.
