Title: Separation of gas components through memb- - ranes
IPC: B01D53/22
Filed: 1970-11-20
Abstract: Separation of a component of a gas mixtures that component being more soluble in a liquid than another component of the gas mixture) is effected by contacting the gas mixture commingled with at least 13.5% of the amt. of the vapour of said liquid required to saturated the gas mixture in a separation zone with a semi-permeable membrane which has the capacity to imbibe the liquid.

Title: Thread core removal - from injection moulding s in injection-mould machines, partic plastic mouldings
Inventor: HEHL KARL
IPC: B29C45/26
Filed: 1971-06-28
Abstract: Thread roots are inserted and unscrewed from injection mouldings by an auxiliary appliance for an injection moulding machine which employes a motor-driven, hollow spindle to apply torque. Adjustable switching elements are associated with stationary switches for determining the start and finish of unscrewing the core of the thread to the extent that they are adjusted. Instead of being connectable to the thread core, the hollow spindle can be coupled to a structural member of the casting mould, and this member can be swivelled about a central angle of 360 degrees in accordance with each work cycle of the injection moulding machine. The arrangement is partic. useful in the moulding of plastic components having threaded parts, i.e. thread roots and screw sockets.

Title: Aza-cycloalkanes electrochemical prodn - by cathodic reduction of lactim O-alkyl ether salts
Inventor: HERBIG KLAUS DIPL CHEM DR
IPC: C25B3/25
Filed: 1974-02-22
Abstract: Aza-cycloalkanes, pref. of Formula (I) (where n is 3-11 and the ring may be substd. by 1 or more alkyl residues and/or an aryl residue, which may be fused onto the ring) (e.g. hexamethyleneimine), are prepd. by cathodic reduction of lactin O-alkyl ether salts, pref. cpds. of formula (II) (where R is alkyl and X is SO4R or BF4), and opt. converting the resulting salts into the corresponding free bases. The products are useful as intermediates, e.g. for plant-protection agents (herbicides) or pharmaceuticals. The process gives good material and current yields. Since the lactin O-alkyl ether salts are electrically conductive, an electrolyte salt is not necessary (even when an aprotic solvent is used).

Patent DE-2448660-A1 (DE)
Title: Drawing plug for pipes - has diameter which is adjustable over small range by forcing it onto conical pin
Inventor: PHILIPP HUGO DR ING
IPC: B21C3/16
Filed: 1974-10-09
Abstract: To compensate for the wear of plugs used for drawing pipes to accurate bore sizes, it is of advantage to be able to adjust the diameter of the plug. This is achieved by providing the plug with a conical bore and by mounting it on a conical pin on which it is secured by a nut. The diameter of the plug can be slightly increased by forcing the plug further on to the conical pin by means of its mounting nut so that elastic deformation takes place. The forces which are exerted on the plug during the drawing process partly relieve the stresses which are induced in the plug by this elastic deformation.

Title: Automatic sunshine and temp recorder - has printed record controlled by timer programmer
Inventor: MEZ ERICH DIPL ING
IPC: G01J5/00

Abstract: The system comprises a pyranometer (1) whose amplified output operates two recording heads with impulse-operated printing mechanisms. One is arranged to give a reading at short intervals, for example, hourly (6) and the second (7) at much longer intervals. A thermometer (8) coupled to the timing mechanism provides an indication of ambient temperature on the same time scale as the pyranometer reading. Sunchine radiation received and ambient temperature are automatically printed on a chart recorder (9) driven by a constant speed synchronous motor. The control of the data print-out is by means of a programmer unit (10).

Title: Replacement brush cover for roller brush spindles - is made on winding mandrel with slotted tube acting as inner support
Inventor: HOLZENLEUCHTER KARL
IPC: A46B3/02
Filed: 1975-02-17
Abstract: The replacement brush cover for roller brushes is made up on a cylindrical winding mandrel fitted with a tube slit along its length and acting as the sliding or separating member so that the finished brush cover can be easily removed from the mandrel and then transported to its place of use, where it can be fitted onto the roller brush. The diameter of the tube is made the same as that of the roller brush core onto which it is to be fitted and whilst still on the winding mandrel the brush cover and its supporting tube are fastened together to form an easily handled one-piece unit. The tube can be made of sheet metal, plastics or cardboard and the slot can be straight or undulating. This slot allows greater tolerances in the size of the winding mandrels since it does not matter how wide the gap is made in order to fit round the mandrel.
