Title: Process for disposing of a cathode ray tube
Inventor: BUTZKE GUENTER
IPC: B03B9/06
Filed: 1993-09-01
Abstract: The invention relates to a process for the recycling of picture tubes or cathode ray tubes having essentially rectangularly designed screens, especially of tubes which are already vented and in which the deflection unit and the tube neck in the length of the electronic system construction, including the electronic system, have previously been removed, decomposition of the tubes, after the removal of the clamping strips and the implosion protection strips, taking place by separating the conical tube part, which is connected by a narrow border area to the screen, from the screen. The separation of the conical tube part (1.3) from the screen (1.1) of the tube (1) is carried out along an intended breaking line produced by means of peripheral linear heating of the border area (1.2), with simultaneous tensile stressing of the screen (1.1) with respect to the conical tube part (1.3). <IMAGE>

Title: Arrangement for attaching a flexible film to a printed circuit board
Inventor: ALTMANN ALBRECHT
IPC: H01R12/62
Filed: 1993-10-19
Abstract: The invention relates to an arrangement for attaching a flexible conductor track film to a printed circuit board, an isotropic adhesive producing (once the influence of temperature and contact-pressure force have been exerted) the electrical connections between mutually associated conductor track contact surfaces. A bracket, which is designed to have a U-shaped profile and is made of non-resilient sheet metal, engages with its limbs around the sections of the mutually connected conductor track contact surfaces, including an elastic plastic strip which is inserted between the flexible film and one limb of the bracket. Once its limbs have been pressed together, the elasticity of the plastic strip in a second state results in the bracket exerting pressure on the connection of the film and printed circuit board.

Patent DE-4405817-A1 (DE)
Title: Automatic equaliser
Inventor: YAMAMOTO TAKESHI
IPC: H04B3/04
Filed: 1994-02-23
Abstract: An automatic equaliser is inserted in a radio transmission path in order to improve the convergence characteristics of a control loop in an automatic equalisation mode if the amplitude ratio of a reflected wave to a direct wave is greater than 1. The automatic equaliser has an adaptive matching filter, a decision feedback equaliser and a reset control circuit to output a first or second reset signal to the adaptive matching filter and to the decision feedback equaliser if an asynchronous condition is detected. Following the generation of the first and second reset signals, whereby the adaptive matching filter and the decision feedback equaliser are reset simultaneously, the first reset signal is removed before the second reset signal is removed. The decision feedback equaliser is thereby switched to automatic equalisation mode after the adaptive matching filter has switched to automatic equalisation mode and has balanced the pulse responses.

Title: Determination of monomer concn. in latex swollen with monomer
IPC: G01N30/02
Filed: 1994-04-15
Abstract: Determination of the monomer concn., Cm,p, in latex swollen with monomer in the heterogeneous phase involves using a combination of pulse-induced emulsion polymerisation and gel permeation chromatography. Polymerisation is induced with an intense pulsed UV lamp, pulsed laser or by rapid addn. of an inhibitor. The polymer emulsion is then removed from the reactor and split. Polymer A is formed by emulsion polymerisation, whilst polymer B is formed by pulse-induced polymerisation of the same monomer in the homogeneous phase at the concn. Cm,hop but otherwise under the same conditions. The mol.wt. distribution of both polymers and the mol.wt. at the point of inflection of the distribution curve, i.e. Mhep for polymer A and Mhop for polymer B, are determined. The value of Cm,p is determined from the equation: Cm,p = Cm,hop x (Mhep/Mhop).

Patent DE-4431862-A1 (DE)
Inventor: TELLER JOACHIM DR
IPC: A61F2/00
Filed: 1994-09-07
Abstract: The invention concerns a method for the electrochemical deposition of hydroxyapatite layers onto metal and ceramic surfaces, the actual electrochemical coating being combined with a pre-coating of the substrates by sol-gel processes, using a calcium and (hydrogen) phosphate-containing electrolyte by means of pulsed direct current. Materials coated in this way are used in the form of biocompatible implants in human and veterinary medicine and are distinguished by particularly high grow-in rates. In contrast to conventional methods of generating hydroxyapatite layers (conventional or microwave sintering of hydroxyapatite produced by the wet-chemical method, deposition by other electrochemical, plasma or laser-aided methods or by sol-gel techniques), this method is distinguished by the application of uniform hydroxyapatite coatings which adhere well and have a small amorphous portion and an optimum layer thickness (5-25 mu m) whilst requiring comparatively low expenditure in terms of apparatus, energy, time and material.

Patent DE-4438927-A1 (DE)
Inventor: DRUMM STEFAN A
IPC: B60T8/48
Filed: 1994-10-31
Abstract: Proposed for a hydraulic brake system which, in addition to braking skid control, has traction control or separate ride-stability control, is the use of a first pump, i.e. a fluid-return pump (18, 24), for braking skid control, while a second pump, a suction pump (22, 23), is connected by its suction line to the master cylinder (1) and by its pressure line to the brake line (4). No special change-over valve is necessary on the suction side of the self-priming suction pump (22, 23) since the suction side does not have to be connected to the low-pressure accumulator (17). In order to keep the cost of such a brake system low, all the pumps (18, 22, 23, 24) in the brake system can be driven by a common motor (25).
