Patent DE-4415492-A1 (DE)
Inventor: BLACKHAM RAYMOND C
IPC: H04N5/262
Filed: 1994-05-03
Abstract: A first set of special effect functions is selected, and start and finish keyframes containing start and finish parameters for the selected effects are specified. The effects can then be run using the start and finish parameters and the number of frames over which the effects are to take place. A second set of special effect functions may be similarly selected, the start and finish frames of the second set being different (but overlapping) those of the first. The two sets of special effects may then be run concurrently to produce complex special effects, eg a background scene has a border which changes smoothly from blue to red over the whole period of the effect, while a foreground scene is moved from a first location to a final location via three intermediate points; whilst the foreground scene moves from the first intermediate point to its final location the background scene changes smoothly from a first to a second video signal. <IMAGE>

Patent DE-4431041-A1 (DE)
Title: Motor vehicle interior passenger space heater
IPC: B60H1/00
Filed: 1994-09-01
Abstract: The interior heater of the vehicle has a heat-exchanger linked to the engine coolant circuit and a variable air flow over the heat exchanger. The heating control is manual and has an automatic override which reduces the rate of airflow if the outside temperature drops below a reference level e.g. 0 deg. C. This ensures that the heating effect is optimised without requiring an additional heater. The outside temperature can be computed in relation to the output of a temperature sensor on the chassis. The air flow rate is progressively reduced with falling outside temperatures, from the limiting level. A minimum air flow of approx. 10% of that at the start of reduction ensures that the heat exchanger is not fully switched off. One method for reducing the air flow is to vary a series-resistance in the blower circuit. This can be a temperature related resistance change.
Patent DE-4438303-A1 (DE)
Inventor: JOHNSON THOMAS KENNETH
IPC: H01J37/315
Filed: 1994-10-26
Abstract: A method of electron-beam welding with in-process heat treatment comprises the steps of, pre-heating a region of the workpiece 20 to be welded by means of a rastered defocused electron beam, welding said region of the workpiece by focusing the electron beam 22 on the workpiece, simultaneously and subsequently controlling the temperature of regions around the welded region by rastering a defocus electron beam 24, 25. The rastering is in a variable pattern and may be at different beam currents as necessary. The invention also includes a computer controlled electron beam welding apparatus adapted to move the beam in both focused and defocused formats over the workpiece, and to alter the beam current in the defocused mode to achieve a necessary heat input for temperature control. <IMAGE>
