Title: Poly:alkylbenzene hydroperoxide prodn. - by pre-oxidn. then adding sulpholane accelerator and continuing reaction on the homogeneous soln.
Inventor: DRESSLER HANS
IPC: C07C409/08
Filed: 1978-06-30
Abstract: Hydroperoxidation of alkylbenzenes of formula (I), (where R1 is 3-6C alkyl with a tert. C atom; R2 is 1-6C alkyl; x is 1-3) with poor solubility in sulpholane (II) comprises liq. phase treatment with O2 (contg. gas) at 75-150 degrees C in presence of 25-150 wt.% (II) (based on (I)). This process is now improved by liq. phase oxidn. of >=10, pref. 15-25% the (I) before adding the (II), then continuing the oxidn. to prod. a homogeneous soln. Specified (I) are m- or -p-diisopropyl-, triisopropyl-benzenes; diisopropyltoluene or 5-isopropyl-m-xylene. The peroxide prods. can be decomposed to mono- or dihydric phenols and acetone by acid catalysis. (II) increases the reaction rate but will normally not work if (I) is insoluble. The pre-oxidn. step ensures a homogeneous soln. so that this accelerating effect is achieved.

Title: Pallet for moving workpieces from place to place - is coated with esp. polyurethane-covered soft mass in which workpieces are (partly) embedded
Inventor: FUEGLEIN EGON DIPL ING
IPC: B65D19/44
Filed: 1978-07-06
Abstract: Pallet for conveying a workpiece(s) from one processing station to another comprises a support which is relatively thickly coated with a plastic mass into which the workpieces being transported are at least partly embedded in transit. The cohesion of the plastic mass is selected so that its cohesion is not impaired when the workpieces are removed at their destination. The plastics mass is suitably coated with an elastic material, specifically a polyurethane, which promotes cohesion of the plastics mass, on the one hand, and facilitates removal of the workpieces from the embeddment, on the other. The coating is suitably glued to the plastics matrix.
Patent DE-2839358-A1 (DE)
Title: Variable transmission system for electromagnetic oscillations - has two coils which are normally decoupled, and is provided with variable coupling
Inventor: SPYRA WALTER
IPC: H04B5/00
Filed: 1978-09-09
Abstract: The oscillations are transmitted from a transmitter coil to a receiver coil. The coils form magnetic dipoles and are practically decoupled, but a coupling can be produced by a ferromagnetic element of an oscillating circuit tuned to the transmitter frequency. The coupling can be mechanically brought to the fields of the coils, or it can be there permanently, but the circuit can be switched. Connecting lines of the magnetic poles (dipole axes) of the two coils are at least approx. parallel. The coils are placed so that when the ferromagnetic element is ineffective, the coupling is minimum.

Title: Air purifier scrubber - with transverse sprays and built in biological liquid reconditioner
Inventor: WAECHTER GERHARD DIPL ING ING
IPC: B01D47/12
Filed: 1978-09-21
Abstract: A scrubbing system to remove foul smelling organic substances from the air emitted by animal farms, abattoirs, cigarette factories, cellulose factories or light metal foundries uses a tower in which the ascending air is washed in several stages by transverse sprays of a liquid medium. The latter drips into packing, coated by a mat of biogenic matter and microorganisms, where it is reconditioned before re-use. This is less costly than combustion or odorant admixture methods and gives more satisfactory results than irradiation.

Title: Rotor to earth fault monitoring device - has fuse between winding and earth, with its conducting state monitored by indicator
Inventor: SCHNELL GOTTFRIED
IPC: H02H3/16

Abstract: The device is for a brushless excited synchronous machine and consists of a fuse inserted between the AC excitation winding and earth, i.e. the mass of the rotor. It is blown by an earth leakage current flowing through it only in case of a fault. The conducting state of the fuse is made visible by the chargng current of the insulation capacitance generated by the excitation generator AC voltage and cused by the rotor winding capacitance to earth. The current flows through an indicator in series with the fuse.

IPC: E21D11/28
Filed: 1979-01-12
Abstract: The mine support system using trough shaped sloing sided channels (10) to form arches to support the rock face, also uses smaller section channels (1) between the arches. These are parallel to the direction of the mine gallery. Their flanges are cropped to clear the beaded edges (8) of the trough shape. Adjacent the beaded edge is inserted an elastomer plug (15) which fits inside the flanges (3, 4) of the small channel. The plug, which is wedge shaped, has a roughened surface (20) in contact with the beading. The assembly can be made more rigid by plates or wire mesh mounted on the upper surface of the small channels.

Title: Cable and conduit bushing with sealing tube - has sealing substance enclosing flanges, one being in form of slidable, annular piston, compressing sealing substance
Inventor: HAUFF WERNER
IPC: F16L5/12
Filed: 1979-01-13
Abstract: The bushing has an outer tube in the wall aperture (3) with a seal of plastically deformable sealing substance (5), filling the space between the tube and wall. The seating substance is held between two flanges (9) on the tube outside, relatively slidable under a force of a clamping device (7). In addition in the tube, the flanges are also sealed pressure-tightly against the wall. At least one flange is in the form of an annular piston, slidable at least over the wall aperture length by the clampin device. Its motion compacts the sealing substance within the aperture. The clamping device preferably uses an external thread, at least on part of the tube. One flange is fixed on the tube, while the other abuts a clamping unit. The fixed flange may form the annular piston. The tube end, carrying the annular piston, may have a branch (10) on the side away from the piston, carrying a flexible sealing sleeve (11).

Title: Paper sheet stacking mechanism - has ream marking device with plunger operated by counting device to form triangular mark on edge of stack
IPC: B65H33/00
Filed: 1979-01-22
Abstract: The sheet stacking mechanism with the sheets deposited on to a stacking table from a belt conveyor above, has a mechanism for marking the stack at each point, corresponding to a ream of sheets. At the receiving point is a counting device which operates a drive member when the number is reached. This has a plunger which operates a marking member which also acts as a stop for the arriving sheets. This member slopes at an angle so that a triangular mark is made on the edges of the sheet. The base of the triangle is level with the top sheet of a ream, then the width of the mark decreases downwards, and the lowest part of the ream is unmarked.

Title: Toilet flush box and pan rinsing container - has holes small enough to retain some water and prevent bubble escape
Inventor: BUCK KARL
IPC: E03D9/03
Filed: 1979-04-21
Abstract: In its operative position flushing water penetrates the unit containing media for cleaning a water closet flush box and pan, which is sited below full flush box water level. There are several through-flow holes with an edge embracing an outlet space outside the container. This is open at the bottom. The overall flow surface area of the holes is such that only part of the water in the containers can flow out in the course of flushing. The flow area of each hole is small enough to prevent any air bubble trapped in the outlet space from escaping upwards. This system is simple and inexpensive, and prevents unnecessary use of cleaner when the flush box is not in use.

Title: Helicopter rotor blade wt. and static moment correction - using weighing instruments and computer controlled balance wt. mechanism
Inventor: FALKENHAGEN HELMUT
IPC: B64F5/00
