Title: Determining head wear of video recorder - measuring attenuation of recorded signal after each test interval and relating to wear
Inventor: WENGER HEINZ
IPC: G11B5/455
Filed: 1993-01-28
Abstract: A reference video tape recorder is used to generate a tape with a reference signal level (Eo) recorded. The tape is then inserted in the recorder used for testing and a second signal is over recorded to reduce the signal level to a new value (E1). The tape is played continuously for a number of hours and the signal level (E2) measured. This is repeated to obtain a signal attenuation characteristic that can be related to head wear. ADVANTAGE - Rapid test directly related to actual wear without simulation.

Title: Cylinder lock
Inventor: RICHTER GERNOT
IPC: E05B19/00
Filed: 1993-07-01
Abstract: The cylinder lock with a cylinder housing (11) and with a cylinder plug (13) rotatable therein possesses, in addition to a row of locking pins (20 to 24), diametrically opposed balls (39, 40, 41) which engage partially into the keyway under the influence of gravity.

Title: Process and apparatus for purifying gases containing hydrogen chloride and sulphur dioxide
Inventor: RAGNARSSON SVEN
IPC: B01D53/50
Filed: 1994-01-19
Abstract: The gases containing hydrogen chloride and sulphur dioxide are scrubbed in a first stage with an aqueous acidic scrubbing solution to absorb hydrogen chloride and in a second stage with an aqueous alkaline water solution to absorb sulphur dioxide. A part-stream (42) is taken off from the acidic scrubbing solution in a first stage and is regenerated in a secondary circuit (43) by neutralisation (44, 45), separating off heavy metals (46-49) and evaporation (50) to separate off sodium chloride (53). In addition, a part-stream (66) is taken off from the alkaline scrubbing solution in the second stage and regenerated in a secondary circuit (67) by addition of lime (69) for separating off gypsum (71) and addition of soda (73) for separating off excess calcium. The invention is primarily distinguished by the scrubbing solution in the first stage being kept essentially separate from the scrubbing solution in the second stage, the condensate from the evaporation (50) in the secondary circuit (43) of the first stage being returned back to the primary circuit (38) of the first stage and by a so-called indirect lime method being used for the regeneration of the scrubbing solution in the secondary circuit (67) of the second stage. <IMAGE>

Patent DE-4403824-A1 (DE)
Inventor: HAERING FRANZ
IPC: B67C3/20
Filed: 1994-02-08
Abstract: A process is disclosed for filling containers with a certain volume of liquid. When an inlet valve (6) is opened, the liquid flows into a volumetric dosing chamber (23), and when an upper switching level (50) is reached the inlet valve (6) is closed. When the outlet valve (7) is opened the liquid flows out of the dosing chamber into a container (1) and when a lower switching level (50) is reached the outlet valve (7) is closed. The top filling level (HO) actually reached after the inlet valve is closed and the bottom filling level (HU) actually reached after the outlet valve is closed are measured. The upper and lower switching levels are corrected by the thus measured values, so that the desired volume of liquid may be accurately respected independently from pressure and flow conditions.

Title: Steering wheel for motor vehicle
Inventor: TSCHAESCHKE ULRICH DIPL ING
IPC: B62D1/11
Filed: 1994-02-28
Abstract: The steering wheel has a rim which bends down on impact. The wheel has at least one spoke in front of the hub central axis and at least one behind it. The one (8) behind it are not so strongly reinforced against bending as the ones (7) in front of it. Therefore, under impact, the wheel rim in the rear zone is less resistant to being pressed down. There may be four spokes, two in front and two behind. Each is covered in foam and plastic. The foam is easier to bend on the spokes behind than on those in front. The foam coverings may be of different cross section. They may be of different hard foam materials but of different thicknesses.

IPC: B62D11/08
Filed: 1994-06-22
Abstract: The tractor brakes are operated by solenoid valves (34, 74, 30, 70) with the brakes on both sides of the vehicle applied together for normal braking and with separate brake control to assist steering. A centrally sprung selector switch (54) provides manual selection of the braking mode and operates in conjunction with the foot pedal brake switch (76). A holding control maintains the brake mode, with the selector switch released, as long as the brake pedal is held below a set threshold. The brake control is linked to steering deflection sensors and inhibits the selected brake steering when a set steering effect is reached. The brake steering is also blocked when the vehicle speed is above a set threshold. <IMAGE>
