IPC: G01N29/24
Filed: 1987-05-23
Granted: 1992-07-29
Abstract: In testing a pipe (8) by means of pulse-type electromagnetic ultrasonic waves, a uniform, axially extending magnetic field is produced in the pipe wall. The coil system (9) which produces the ultrasonic pulses and which receives the ultrasonic waves reflected in the pipe wall is of ring-shaped construction and surrounds the pipe (8). The axis (10) of the coil system (9) extends eccentrically with respect to the pipe axis (12) and the coil system (9) is moved in two axes extending perpendicularly to each other and perpendicularly to the pipe axis (12) in such a way that the axis (10) of the coil system (9) performs a circular movement (11) around the pipe axis (12). As a result, the region of contact (13) between coil system (9) and pipe (8) moves around the pipe (8) without the coil system (9) itself rotating about its axis (10). In this way, it is possible to test the pipe (8) over its entire circumference without interruption. <IMAGE>

Abstract: A device for tapping beer or the like from cans comprises a housing with an outlet closable by a tapping valve and an air pump. Attached to the housing is a piercing pipe which can be introduced into the can and forms a beer discharge channel which is in communication with the outlet. The air supplied by the air pump flows separately from the beer through lateral air outlet openings of the piercing pipe into the can above the level of the beer and applies pressure to the beer. The flow cross-section of the beer discharge channel in the piercing pipe is determined substantially throughout its entire length by the internal diameter of this pipe. A thin-walled sleeve of smaller external diameter than the internal diameter of the piercing pipe which separates the beer discharge channel from the flow path of the supplied air and which is sealed relative to this channel below the air outlet openings is provided in the upper region only of the piercing pipe.

Abstract: Each fluorescent lamp (1) is assigned a louvre system consisting of a parabolic longitudinal reflector (2) and numerous crossblades (3) consisting in each case of two parabolic limbs. The aim is for the light to be brought from the lamp indirectly in an oblique direction onto a workplace via the crossblades. So that light cannot be emitted directly between the crossblades (3), the gaps are covered, on the one hand by cover plates (4a) parallel to the lamp which adjoin in each case the base of the crossblades, and over the remainder by cover plates (4b) which are likewise parallel to the lamp but are arranged in an upper plane at a slight distance from the lamp. Without appreciably changing the basic design of the lighting fixture, it is possible to determine the extent and direction of the indirect light reflection by a wider or narrower construction of the upper cover plates or by overlapping. For the rest, it is also possible for the lower cover plates (4a) to be used to emit light by radiating (6) upwards via an opening (2a) between the longitudinal reflectors. <IMAGE>

Title: Process for the production of thermally stable layers with a great hardness and/or low-friction properties
IPC: C23C14/32
Filed: 1988-12-01
Granted: 1993-10-06
Abstract: A process for the production of layers which have great hardness and/or low-friction properties, in particular based on micro- or nanodisperse carbide carbon layers, is proposed. A target material to which an electric potential is applied is converted in a vacuum into a target plasma. The target plasma reaches the substrate which is at an electric potential approximately equal to or higher than that of the target material and forms the desired layer on said substrate. The target material is formed by a titanium alloy, the titanium alloy being vaporised by means of an arc to give a titanium alloy plasma. The conversion of the titanium alloy into the plasma is carried out in the gas phase of ionised carbon. The process is operated by a method in which titanium alloy carbide, gaseous titanium alloy and carbon are formed, the carbide of the titanium alloy, the titanium alloy and carbon being formed, in succession on the substrate, as a ternary layer which additionally has thermal stability.

Title: Tetrabromobisphenol-a process
IPC: B01F5/04
Filed: 1988-11-07
Granted: 1993-04-07
Abstract: Tetrabromobisphenol-A is made in high purity by adding a methanol-bromine solution to a methanol-bisphenol-A solution with vigorous agitation. Use of the bromine-methanol solution reduces the amount of by-products compared to the use of liquid bromine feed to a methanol-bisphenol-A solution. The process is readily adapted to large scale equipment by circulating the reaction mixture from the reaction vessel through an external closed loop which includes an impingement mixer. The bromine-methanol feed is pumped at the proper rate and ratio into the impingement mixture whereby it impinges with the circulating reaction mixture. The resultant bromination mixture is then returned to the reaction vessel.
