Patent DE-2135144-A1 (DE)
Title: Pipe welding method
Inventor: BOER LEENDERT
IPC: F16L13/02
Filed: 1971-07-14
Abstract: Internally anti-corrosive coated pipes are welded after sliding a push fit sleeve over each pipe end. Both pipe ends are machined with a circumferential groove in the bore. The sleeve over one pipe end projects some distance over the pipe end-face and has a circumferential internal groove, machined to form part of a small airchamber, which is formed when the second sleeve provided with a slealing lip at its end is pushed home to fit inside the groove in the first sleeve. The chamfered ends of both sleeves enable a seal weld to be made. Flame impingement to the coating during welding is thus avoided. The outer ends of both sleeves are also sealwelded.

Title: Lift safety brake catcher mechanism with centrifugal trip - has brake parts loaded by adjustable spring
Inventor: PAESERACK ULFERT
IPC: B66B5/04
Filed: 1973-06-15
Abstract: One component of the safety brake rotates in a housing, and is coupled by the action of a centrifugal trip to a rotor, positively driven when the cage is descending at least. When this component is not coupled to the rotor it is spring-loaded against a stationary brake component in the housing. The abutment of the spring furthest from the brake components is connected to a holder detachably secured to the housing, allowing its adjustment in the direction in which the spring acts. Where the brake is of the multiplate type, the abutment can be mounted so as to slide, but not turn in the housing in the axial direction, being held by a threaded component screwing into the holder.

Title: Vehicle pneumatic tyre with convergingly inclined sidewalls - which bend inwards when load is applied to the tyre
Inventor: WITTNEBEN HERMANN DIPL ING
IPC: B60C3/00
Filed: 1973-09-24
Abstract: A pneumatic tyre has a cylindrical tread, a circumferentially tenacious (tensile-strong) contact surface strip, and non-reinforced sidewalls which are inclined towards each other. The contact surface strip resists elongation in an axial direction in such a way that, when the tyre is running, the distance between contact surface strip and tyre sidewalls does not increase. As a result. the sidewalls "cave in" on appln. of a load without generation of damaging or destructive tensile stresses. The contact surface strip may be provided with fibrous parallel, axially arranged, reinforcements.

Filed: 1973-09-26
Abstract: The motor and fan assembly has a casing which houses the motor and is attached to a centre casing which, together with the end casing, houses the fan which is provided with radial blades. Incoming air flows through the radial ports around the motor into the fan casing, then radially outwards over the circular heating element and into the hood through the ports. The projections provide an airspace above the hair so that warm air can circulate through the perforations in the hood surface. The design is lightweight and is easy to manipulate in use.

Title: Two inductor HF-cable for inductive receiver coupling - uses conductor combs deposited on a band of synthetic material
Inventor: BREITENBACH OTTO
IPC: H01P3/08
Filed: 1973-09-28
Abstract: The HF-cable permits the transmission of HF power from a transmitter to a receiver which is movable along the cable over a defined distance. The receiver is inductively coupled to the cable as used for automatic train control. The two conductors are deposited on a carrier of synthetic material. Each conductor is comb shaped and the conductors oppose each other with the comb teeth in such a way that the comb teeth of the two conductors are separated from each other by a strip of nearly constant width of the synthetic material, such as polyester or glass-silk. The electrical resistance of the synthetic must be large compared with that of the conductor, but small compared with that of an insulator. For conductors on the same side of the carrier the teeth of one conductor fall in the gaps between the teeth of the other conductor.

IPC: H05B6/06
Filed: 1973-10-05
Abstract: In case of a three-phase supply the coil can generate a moving magnetic field to carry out metallurgical reactions in the crucible, or in case of a single-phase supply the charge is molten in the crucible. At a melt level in the crucible corresponding to the whole coil height during moving field operation, the top section of the coil is disconnected when operated from a single-phase supply. In this case the operating coil sections are connected to a secondary windings of transformers, whose primary wiondings are in parallel with the power supply, and one transformer secondary winding and capacitor battery of the disconnected, upper coil part, are connected in a V with the middle and lower coil parts. A balancing inductor is connected to the above V-circuit.

Abstract: Drug regime for the treatment of epileptic states comprises (a) at the beginning of treatment and for a certain initial period continuously decreasing dosage of a drug usual in the treatment of epilepsy (pref. 5-phenyl-5-ethyl-hexahydro-pyrimidine-4,6-dione (I)), simultaneously with (b) moxisylyte hydrochloride (4-(2-dimethylaminoethoxy)-5-isopropyl-2-methylphenyl acetate hydrochloride (II) in the dosage required for prolonged treatment (ca 5 mg/kg/day). Initial combination of (II) with decreasing dosage of a conventional antiepileptic avoids fits if (II) is introduced by itself, but the benefits of long-term therapy with (II) (mental alertness, ability to work) are retained.
