Patent DE-4102832-A1 (DE)
Title: Reducing access time in CD player etc. - raising disc speed between start of track transfer and time of reaching target location on target track
Inventor: BAAS DIETER
IPC: G11B7/085
Filed: 1991-01-31
Abstract: The method of reducing access time in a CD player involves increasing the speed of the disc when changing track, before the target track is reached. When the target location has been reached, within given tolerances, the disc speed is re-set to the appropriate speed for the track. The speed of the disc may be raised immediately when a track change has been initiated, or only when the distance to the target location is above a set threshold. USE - Also for video disc, DRAW-disc and magneto=optical disc players.

Title: Printed fabric design - is made fast to washing by pressure and heat transfer of fixing agent from a sheet carrier
Inventor: BECHTOLD RUDOLF
IPC: D06P1/48
Filed: 1991-05-10
Abstract: Design using a dyestuff and any necessary bonding agent, applied to a textile fabric, is made fast against washing out by the application of a fixing agent from a carrier sheet. When the fixing agent has dried on the carrier sheet, the coated side of the sheet is placed on the applied design for at least a partial transfer through pressure and/or heat. The carrier sheet coating is transferred at least partially to the printed fabric design at a pressure of 2.0-3.5 tons and/or a temp. of 180-240 deg.C. and pref. about 220 deg.C. The fixing agent is a basic mixture of a textile dyestuff hardener mixed with ground vegetable seeds, such as ground corn or wheat at a rate of 20-30 Vol.% hardener and 70-80 Vol.% of pap. The pap is composed of one vol. part flour to 2-3 vol. parts water or similar liquid, and pref. 2.5 vol. parts. The water content for the mixt. contains dissolved ammonium sulphate at a rate of about 20g ammonium sulphate per litre. About 0.5-3 vol. parts of liquid ammonia are added to the basic mixture for every 100 vol. parts of mixture, and at a pref. rate of one vol. part per 100 vol. parts. Acid salts are added to the basic mixture at a rate, per 100 vol. parts, of 0.25-0.5 vol. parts esp. as a 10% acid salt solution. To 100 vol. parts of the basic mixture are added 0.25-0.5 vol. parts of acid salt and 0.3-0.5 vol. parts of liq. ammonia. The fixing agent is brought to a pap or paste consistency by the addn. of a bonding agent. The paper carrier sheet has a polished surface to take the spread fixing agent. ADVANTAGE - The method gives a simple and rapid protection of a printed fabric design against washing out

IPC: F42B12/18
Filed: 1991-10-26
Abstract: A tandem warhead comprising a forward (3) and main (7) hollow charge, sepd. by an explosion gas shield (6). The latter is tapered forwards and consists of a forward part (11) and a rear part (12), both parts being held together by a ring-shaped clamping component (13). The explosion gas shield (6) absorbs most of the explosion gas energy (15) on detonation of the forward charge (3), by its plasic deformation.
