IPC: B24B3/26
Filed: 1985-02-13
Granted: 1988-06-16
Abstract: The apparatus for grinding twist drills comprises a shaft and a grinding wheel which has a grinding surface and is rigidly secured to the shaft. The apparatus comprises also a drill-guiding body, which faces the grinding surface and is axially spaced from it and axially immovable relative to the grinding surface. The drill-guiding body is formed with a plurality of guiding passages for guiding twist drills differing in diameter toward the grinding surface. At least one guide lug is aligned with each guiding passage of the drill-guiding body and adapted to extend into a flute of a twist drill extending through the associated guiding passage. All guide lugs are mounted on a guide lug carrier, which is mounted to be axially movable between the drill-guiding body and the grinding surface and which is biased toward the grinding surface by a spring. At least one abutment consisting of a material which has a higher hardness than the grinding wheel is secured to the guide lug carrier and has an abutment surface which is parallel to and engageable by the grinding surface. This arrangement ensures that a constant distance from the guide lugs to the grinding surface will be maintained during the grinding operation in spite of the wear of the grinding wheel and the original shape of the grinding surface will be restored.

Title: Cooker extruder
Inventor: SCHAAF HEINZ
IPC: A23P30/25
Filed: 1985-08-30
Granted: 1988-12-01
Abstract: In this cooking extruder the nozzle head (12) is disposed in a nozzle plate (10) and the passage (34) through which the material for the envelope body is supplied extends at an angle to the axis of a filling tube (42) through which the filling material is introduced into the extruded envelope body.

Inventor: LOGES HANS-JOACHIM DIPL ING
IPC: B21D19/02
Filed: 1985-06-13
Granted: 1989-11-16
Abstract: An apparatus for shaping a strip, especially a metal strip includes a pair of working rolls which are provided with a plurality of forming tools spaced about the circumference of the rolls. Arranged before the working rolls is a pair of guide rolls which run in synchronism with the strip speed. In order to be able to increase the operating speed of the apparatus, i.e. to allow the working rolls to run at a higher speed than the advance speed of the strip, in between the guide rolls and the working rolls a roller is located which is movable in a direction perpendicular to the advance motion of the strip and is supported by the strip itself and by springs located in respective casing. A compensation between the different speeds of the guide rolls and the working rolls is provided by the gradual depression of the roller by the strip against the force of the spring.

Granted: 1990-12-13
Abstract: The disclosure describes an anode made of a thin metallic foil in discharged condition which is converted into a dense metallic alloy of an alkali metal during the first charge. The disclosure also describes an electrochemical rechargeable battery in discharged condition. The latter comprises an anode made of a thin metallic foil, such as aluminum, magnesium or tin, an electrolyte, for example a polymeric electrolyte, as well as a cathode based on an oxide, a sulfide or an halide, prepared in discharged condition and constituting a source of alkali metal preferably lithium. The cathode should be capable of freeing the alkali metal under a charge so that the latter is introduced into the metallic foil to form an alloy of the alkali metal and of at least a portion of the metal consitituting the metallic sheet. To obtain the charged batery, it is merely sufficient to apply a charge during a certain period of time while the anode is being transformed into an alloy. Substantially improved properties during cycling.

Abstract: In a time base correction system, a composite color television analog signal derived from a prerecorded tape is converted by an analog-to-digital (A/D) converter to a digital signal having horizontal sync and color burst signal components. The digitized sync and burst signals are processed on a line-by-line basis to provide an error signal between input video and a sampling clock in the form of a binary control word. The error signal is applied to a digital frequency synthesizer which generates a clock at the subcarrier frequency to achieve precise adjustment of frequency and phase of the A/D sampling clock with respect to the video signal. An analog phase locked loop operating at four times the subcarrier frequency feeds back a 4x subcarrier sampling clock to the analog-to-digital converter with adjustable frequency and phase.
