Abstract: A device and a method for using overcapacities in the power grid is provided. In case of an oversupply of energy, the energy is transferred to a thermal storage device directly via a heating element and in the discharge case of the thermal storage device the heat is removed from the thermal storage device and made available to a thermodynamic cycle whereby electrical energy is produced. The heat from the thermal storage device is used to preheat air in an air feed line to a combustion chamber, or fuel is pre-heated using heat from the thermal storage device.

Abstract: A rollover wash unit for a vehicle wash system includes interspaced lateral parts (2, 2?) fitted with guides (12, 12?), and a treatment device (7) that is received in the guide elements (8, 8?) via bearings (9, 9?), the guide elements being displaceable in the guides (12, 12?). In order to achieve an adaptation to the washing height, the guide elements (8, 8?) are configured to enable the bearings (9, 9?) to project beyond the guides (12, 12?) in a final position of the guide elements (8, 8?) in the guides (12, 12?), where the treatment device (7) projects upward beyond the lateral parts, (2, 2?) and/or an upper edge of a traverse (5) connecting the lateral parts (2, 2?), in an uppermost position of the guide elements (8, 8?).

Abstract: A rotating metallic workpiece, the hardness of which lies within the interval of 45-65 HRC, is turned by a cutting insert while being rotated about an axis. The insert has a cutting edge made of cubic boron nitride. The cutting insert is fed in a feed direction into the rotating workpiece, by a distance which is shorter than an effective cutting edge length in order to cut a surface having a finish Ra of maximum 0.2 &mgr;m. The ends of the cutting edge are situated outside the zone of contact with the workpiece.

Abstract: A flash control circuit for a camera flash circuit in which a scene ambient light sensing circuit is coupled to the main flash capacitor which serves as the sole energy source for the light sensing circuit independent of the battery source. The ambient light sensing circuit comprises a light sensing device and resistor coupled in series across a zener diode which serves as a fixed voltage reference device for the light sensing circuit. In a preferred embodiment, the ambient light sensing circuit is coupled in series with the flash sync switch across the flash capacitor such that activation of the light sensing circuit occurs only while the sync switch is closed.

Abstract: A camera includes a self-timer operable to delay picture taking for a predetermined interval and an electronic flash having a variable re-charge time. Operation of the self-timer is prevented when the predetermined interval is less than the re-charge time of the electronic flash.

Abstract: A camera includes a shutter button for commencing a picture taking sequence to record an image on a photographic filmstrip and a mode button for selecting an operating mode of the camera. The mode button is operable to select a mid-roll rewind mode of the camera in which the filmstrip, having one or more unexposed image frames, is wound back into a cartridge in the camera. The mid-roll rewind mode is actuated by the shutter button. Preferably, the shutter button must be operated for a longer period of time to actuate the mid-roll rewind mode than to commence the picture-taking sequence.

Abstract: An apparatus for photo-electrically interfacing a mechanical camera component to an electrical camera component in a camera. The mechanical camera component has a sensing area associated therewith. The sensing area contains optically detectable information. The apparatus comprises a device for directing radiant energy to and from the sensing area. The radiant energy is incident upon at least a portion of the optically detectable information contained on the sensing area. A detecting device is optically coupled to the directing device for photodetecting radiant energy received from the optically detectable information. The detecting device provides an electrical output for receipt by an electrical camera component. The operational status of the mechanical camera component is determinable by the output of the detecting device. The directing device includes an optical fiber having a distal end and a proximal end.

Abstract: A flexible printed wiring arch connector, having first and second sets of finger-like projections integrally formed on opposite sides of an elongated substrate, is adapted to be inserted and flexibly secured into corresponding apertures of a receiving printed circuit board. A plurality of electrical conductors are formed on the substrate along the elongated dimension thereof. Connector leads, formed on the finger-like projections, are electrically connected to desired individual ones of the conductors and extend in a direction generally perpendicular to the conductors. Arcuate bending of the projections and connector leads in a direction crosswise of the elongated substrate disposes the projections and connector leads for insertion and retention under a restoring spring force in the circuit board apertures. Once flexibly secured in place, the flexible printed wiring arch connector is ready for soldering.

Abstract: A recycleable element includes a means for visually indicating the number of times the element has been recycled whereby the indicating means is updateable each time the element is recycled, up to a maximum recycleable life of the element. Such a recycleable element is particularly useful in a recycleable film pack single-use camera having a built-in electronic flash unit.
