Patent DE-4200351-C1 (DE)
IPC: B21C47/00
Filed: 1992-01-09
Granted: 1993-01-28
Abstract: A metal strip wound up in a coil on a feed spool is split by supporting the feed spool for rotation about a horizontal axis and passing the strip along a generally horizontal feed plane through a rotary-blade cutter and subdividing the strip at the cutter into a plurality of even substrips and a plurality of odd substrips interleaved with the even substrips. The even substrips are guided upward in an upper plane forming a small acute angle with the feed plane from the cutter to a respective even-strip windup spool and these even substrips are wound up on the even-strip windup spool. The odd substrips are guided downward in a lower plane forming a small acute angle with the feed plane from the cutter to a respective odd-strip windup spool and these odd substrips are wound up on the odd-strip windup spool. The cutter and the feed spool are rotated at substantially the same speed and both the windup spools are driven at a speed slightly greater than the speed of the cutter and feed spool to pull the substrips from the cutter and the strip from the feed spool. The positions of the spools are adjusted to maintain the planes in substantially the same orientation relative to one another.

Title: Text insertion procedure for dictating machine - recording individual text on magnetic recording tape with text insertion identification points
Inventor: MITTELSTAEDT RAINER DIPL ING
IPC: G11B27/024
Filed: 1993-02-25
Granted: 1994-01-20
Abstract: The insertion method uses a semiconductor memory to retain the text sections (TT) and the individual text (T) temporarily before transfer to the magnetic recording tape (MB). The individual text is directly recorded on the magnetic recording tape, together with an identification (A) for each text section insertion point. Each identification is detected to allow the insertion of the text sections held in the semiconductor memory at the correct points. The text sections are fed back into the semiconductor memory when the magnetic recording tape is loaded in the dictating machine. ADVANTAGE - Allows insertion of common text sections for several documents in individual text for each specific document.

Title: Sieve arrangement
Inventor: RUMPF WOLFHARD DIPL ING
IPC: B07B1/22
Filed: 1993-09-18
Granted: 1994-08-18
Abstract: A sieve arrangement (1) is indicated, with a housing (2), a main sieve (5) and a pre-sieve (9) which bears a main striker mechanism (15) for the main sieve (5) and can be moved relative to the main sieve. In such a sieve arrangement, the pre-sieve tends to get blocked when material which tends to form clumps is to be sieved. In this case, frequent maintenance is necessary. The present sieve arrangement is to be more universally usable. To this end, the pre-sieve (9) is divided into a second (10) and a first (11) part. The second part (10) bears the main striker mechanism (15) and can be moved relative to the first part (11). An auxiliary striker mechanism (19) which can be moved relative to the first part (11) is provided. <IMAGE>

Abstract: Each nozzle (4) has a throttling pintle (18) between the needle-valve (5) and the injection hole (17), which widens towards the outlet. Thus the free cross-section increases with increasing needle stroke, giving an injection characteristic curve which is generally triangular, with a flat rising flank and a steep falling one.The pintle can be arranged to taper, while the outlet is cylindrical. The opening of the nozzle valve is controlled by the low pressure side of a pressure regulator.

Title: Method for the generation of thrust in jet engines
Inventor: COHRT CLAUS
IPC: F42B19/26
Filed: 1993-11-18
Granted: 1995-04-27
Abstract: In a method for the generation of thrust in jet engines, in particular for underwater driving purposes, a water-reactive propellant is brought into contact with water and the kinetic and thermal energy released during this reaction is used for generating propulsions. The reaction is conducted in a two-stage process, in the first stage the proportion of water to reactants being sharply under-stoichiometric, and in a second stage the residual portions of the propellant, which portions are contained in the resultant reaction mixture, are reacted accompanied by an excess amount of water. The first stage of the reaction takes place in a separate prereaction chamber which has its own supply system for the reactants.
