Title: Non-uniform spring wire for vehicle suspensions - is rolled to non-uniform size and stripped by metal cutting
Inventor: LINDEMANN HANS
IPC: B23B5/12
Filed: 1977-11-11
Abstract: The spring wire is stripped to have variable cross section along its length. Relatively little material is moved in stripping process. The profile of the rolled wire is deformed before stripping to reduce machining on stripping. The profile is rolled so that the wire stripping process takes place with uniform cutting depth. Spring made from such wire are used in motor vehicle suspensions. The rolls are controlled accordingly so that wire lengths of smaller diameter ends can be produced.

Title: Device rotating vacuum segments on coaxial orbital path - transfers labels from stack to rotating cylinder after semi-circular traverse
Inventor: KOERTGE LUTZ
IPC: B65C9/14
Filed: 1979-02-23

Title: Calcium phosphate catalyst prepn. - by reacting calcium salt with phosphoric acid salt under mol. ration and pH control
Inventor: BITJERASCH JULIA A
IPC: C07C1/247
Filed: 1979-07-18
Abstract: Ca phosphate catalysts are prepd. by reacting Ca salts, (I), with phosphoric acid salts, (II), in an aq. ammonia medium, sepg. the ppte. formed from the reaction mixt., shaping the bottom sediment and drying. Novelty consists in (a) reacting (I) and (II) in (I) : (II) mol. ratio 1.5 : 1 to 5 : 1 (2.5 : 1); and (b) treating the reaction mixt. with H3PO4 soln. to pH 5-7 (5.5-6) before sepg. the ppte. The catalysts are used in isoprene prepn. from isobutylene and HCHO and in alcohol dehydration, esp. in the dissociation of 1,3-dioxans, partic. 4,4-dimethyl-1,3-dioxan, (A), to isoprene. Mol. ratio control (a) and pH control (b) in catalyst prepn. increase catalyst activity, lower operating temp., increase efficiency, catalyst life and isoprene selectivity and also lower coke deposition in (A)-dissociation. E.g. catalyst selectivity to isoprene is increased to 84-85.8 mol.%, i.e. by 3.8-6.6 mol.%. At 320 deg.C, conversion is increased by 20-25%, e.g. to 96-96.6% and catalyst activity is 0.8 t isoprene/cu.m.catalyst.hr. Catalyst life can reach 1500 hrs.
