Patent DE-3268762-D1 (DE)
Title: Circuit arrangement for charging a battery with direct current pulses
Inventor: HARRI KURT
IPC: H02J7/10
Filed: 1982-05-03
Granted: 1986-03-13
Abstract: The charging device contains a two-part conductor bar (18', 18''), the two parts of which can be connected by means of a contact pair (32). When the contact pair is closed, the conductor bar connects a connecting terminal (15) for the accumulator battery (16) to be charged with the primary winding of a firing transformer (37) and with a device (33, 34, 36) for energizing the firing transformer as a function of the voltage of the battery. When the contact pair is opened, the primary winding of the firing transformer and the aforementioned device are separated from the connecting terminal. In addition a control circuit (31) for the contact pair is provided, which receives a first input signal from a timer (26) and a second input signal from a series resistor (12) in the charging circuit. The control circuit contains means which close the contact pair during the period determined by the timer, so that the firing transformer is energized as a function of the voltage of the battery, and open the contact pair after expiry of the predetermined period as soon as the charging current exceeds a presettable value. In this manner it is possible to charge a battery and/or to maintain a limited maintaining charge during a period of any desired length and to interrupt the charging operation when a battery does not reach the set-point of its voltage in the predetermined period.

Title: Apparatus for manufacturing toothed wheels by rolling-spark cutting
Inventor: KUIKEN HENDRIK
IPC: B23H1/00
Filed: 1982-10-05
Granted: 1986-07-03
Abstract: Method and apparatus for the manufacture of internal or external toothed wheels by spark-erosion [spark-cutting] only, whereby a normalized involute cylindrical toothed wheel, acting as electrode, is unrolled over the workpiece to erode a toothing into the [cylindrical] circumference and/or in the side face[s]. The path of the electrode wheel is controlled during its unrolling motion by a follower-involute tooth wheel running without clearance over a narrow involute-rack bent into a circle and fixed to the machine. A standard high-precision spark erosion machine being used, the feed-control is adapted to hold the workpiece and to have the electrode wheel at each pass sink itself deeper into the material of the workpiece, as function of the momentary to the set sparking-power. The whole width of the teeth is machined in the same operation. The workpiece may consist of hardened or other normally unmachinable material. Especially a <<crown-wheel>>-like involute toothing may be made to co-operate with standard involute pinions, maintaining all known advantages of involute toothings, although the shafts are under any angle, including 90 DEG .

Title: Process for preparing biopterin and its derivatives
Inventor: VISCONTINI MAX
IPC: C07D475/04
Filed: 1982-11-10
Granted: 1987-04-09
Abstract: A novel compound, 1',2'-diacyl-(6R,S)-5,6,7,8-tetrahydro-L-biopterin which is prepared by catalytical hydrogenation of a 1',2'-diacyl-L-biopterin in a solvent in the presence of a catalyst. The 1',2'-diacyl-L-biopterin is prepared from a 1,1-dialkylsulfonyl-L-rhamnose through an acyl derivative of 5-deoxy-L-arabinose and a hydrazine derivative of tetrahydro-L-biopterin without isolating the intermediate products. The 1', 2'-diacyl-(6R,S)-5,6,7,8-tetrahydro-L-biopterin can be used for treatment of atypical phenylketonuria or dihydropterin-reductase deficiency and can readily cross the blood brain barrier without neurotransmitter precursors.

IPC: G06K9/62
Filed: 1983-09-06
Granted: 1988-01-21
Abstract: The described pattern matching apparatus, e.g. for speech recognition systems, improves the known so-called VC pattern (Vowel-Consonant pattern) method in reducing the user's reference pattern-registering load, memory capacity and computation amount.

Title: Easily releasable mat holder
Inventor: JONES W GREGORY
IPC: A47G27/02
Filed: 1985-12-20
Granted: 1989-05-18
Abstract: Improved holder specially adapted for disposable floor mats to be placed adjacent entryways to factories, industrial buildings, or the like or for use in connection with clean rooms, hospitals, laboratories. The holder includes a flat base adapted to hold the mat and at least one hingedly connected side flap adapted to fold over on top of an edge of the mat and securely retain it in position. Means are included to hold the flap against the mat in a closed position to firmly resist movement that would cause wrinkles or bunches in the mat which could cause trips or falls. In accordance with the invention, the base support includes at least one hand hole adjacent the edge of the base and located so as to be covered by the flap in the closed position. By means of the hand hole, direct pressure may be applied directly against the flap or by pressing against the mat so as to overcome the holding means and greatly facilitate opening of the flap to release the mat when desired. Preferred embodiments include materials of construction that are rigid and sufficiently heavy and have a nonskid surface so as to resist movement of the structure and the embodiment wherein two hand holes are included in each side having a hinged flap so as to allow pressure to be exerted at spaced locations and further facilitate opening of the flap.
