Title: Plastics and metal bonding - involves applying metal oxide layer to metal carrier by friction to hold adhesive and secure plastics for dental prosthesis prodn.
Inventor: KOHLER PETER JOCHEN
IPC: A61C13/00
Filed: 1992-04-06
Abstract: To produce a metal and plastics bonded material, an adhesive and amorphic metal oxide layer is applied to a metal carrier by friction, for a plastics to be bonded in place by an adhesive silane. During working, a relative movement is exerted between the metal carrier and a tool which carries the metal oxide forming component. During the friction action, the metal oxide layer is deposited on the metal carrier. Also claimed is an appts. with the metal oxide material held in the point of a tool (1). The relative movement between the tool and the carrier is by tool rotation or by ultrasonics or piezo-electric oscillation. The metal oxide is a powder, sintered to the tool (1), or the tool is porous body (6) impregnated with a metal oxide, bonding solution or paste. Or the metal oxide fluid is applied to the tool (1) surface. The porous tool body (6) can also be hollow, with a hollow zone (8) for the fluid. The metal oxide can be sintered on a carrier pin (2). The tool head can be a sintered body (6) in different shapes. USE/ADVANTAGE - The bonded material is esp. for a dental prosthesis. It gives the application of an adhesive layer on the carrier, selectively, and also applies to prosthesis repair.

Inventor: HERTRAMPF JOACHIM
IPC: C02F1/78
Filed: 1992-05-21
Abstract: Organic substances in biologically pretreated waste water are oxidised by ozonising with an ozone-containing gas in at least two reaction vessels (1, 2) connected in series and UV irradiation in a UV reactor (5). To reduce the size of the reaction vessels and decrease the specific ozone consumption, the reaction vessels through which the waste water successively flows are operated at pressures increasing from vessel to vessel. The ozone-containing gas flows through the vessels in counter-current to the waste water. The introduction of the ozone-containing gas from one reaction vessel to the subsequent reaction vessel proceeds as a result of the pressure drop. <IMAGE>

Title: Depth adjustment of amplitude of echo signals using ultrasonic measuring unit - working according to pulse reflection method and leading pulses from test heads to test bodies arranged staggered in depth at known distances from surface
Inventor: VOLKMANN KLAUS
IPC: G01N29/44
Filed: 1992-10-15
Abstract: The test bodies have as many as possible similar defects, at which pulses are reflected so that they arrive back at the original test head or another head of the ultrasonic measuring unit. They arrive in a timed stagger corresp. to the local depth grading. This leads to electrical signals being generated of different amplitude at the receiver part of the ultrasonic measuring unit. The electrical signals with their amplitude and time values are stored (40) as base points. A digital correction signal for each defect is obtained from the deviation of the signal amplitude of each individual base point from an associated reference amplitude in a comparator (34). The signal, after conversion in a D-A converter (46), is used for controlling a variable amplifier so that, with a successive measurement of the same material at similar defects, equal value amplitudes of echo signals are delivered independent of depth. The adjusting curve for the amplifier is activated. ADVANTAGE - Max. depth of correctable depth range is practically unlimited. Smaller storage capacity is needed. High resolution and linear interpolation between non-equidistance base points is possible.

Title: Double recording VCR with video correction circuit - simultaneously records radio signals from two channels and selectively plays back either or both recorded signals
Inventor: SHIN JOONG IN
IPC: H04N9/82
Filed: 1992-11-25
Abstract: A first signal input device (31) receives a first channel signal and detects video and audio signals from it. A second input device (32) enters a second channel signal and detects video and audio signals from the input devices and processes them. An audio signal processor (63) processes the audio signals from the input devices. A recording device (63) records the audio and video signals of the first and second channels and these are recorded on the tracks of a video tape. A playback device (60) reproduces stored audio and video signals. The signals are processed by video (64) and audio (63)  processors respectively. A video signal corrector (65) compensates the video processor (64) output for omitted signal parts. The outputs of the audio processor (63) and the video signal corrector (65) are transmitted to a radio medium. ADVANTAGE - Simultaneously records radio signals from two channels and selectively plays back recorded signals so is more efficient and reduces mfg. costs.

Title: Device for mounting a light strip of a motor vehicle
Inventor: SELINGER JOACHIM
IPC: B60Q1/26
Filed: 1993-06-26
Abstract: The invention relates to a mounting device for a light strip of a motor vehicle with a panel arranged between lights. In order to ensure both unproblematic behaviour with respect to thermal expansion and achieve precise alignment of the individual elements with respect to one another and with respect to the body of the vehicle it is proposed to secure the panel, arranged between the lights of the motor vehicle, centrally with respect to the body of the centre of the vehicle. The lights of a motor vehicle are connected to the panel at one end and to the body of the vehicle at the other, the connection between the light and the panel being displaceable in the direction of the longitudinal extent of the panel and being bendable in a horizontal plane. The light strip which is formed from the two lights and the panel is thus supported centrally on the body of the vehicle at its end point. In the subclaims, advantageous developments of the invention are described. Thus, at least one second, off-centre mounting point is provided which can however be moved in the longitudinal extent of the panel. As a result of the distance between the first and second mounting points, the alignment of the panel can be maintained even in the case of relatively large forces acting on the panel.
