Patent DE-2344372-A1 (DE)
Title: Balancing induction-coil for communications technology - with recess flange for insert, locking with bell-core
Inventor: JERNEY RUDOLF
IPC: H01F17/04
Filed: 1973-09-03
Abstract: The coil has a roller-core with bottom and thread flange, a winding and a bell-core with internal thread, which is screwed on to the thread-flange. The surface of the thread flange not facing the bottom-flange has a slit-type recess, into which a non-magnetic pref. thermoplastics, e.g. PTFE platelet-insert is placed. The dia. of the latter exceeds that of the thread flange, but is less than the external dia. of the thread of the flange, so that the edges of the insert lock with the thread of the bell-core. The advantage of these induction-coils is that they have a so-called threaded brake so as to eliminate the thread-clearance between the threads of the coil-core and of the bell-core, as a result of which continuous balancing of inductance is maintained.
Patent DE-2350550-A1 (DE)
Title: Cylinder head gasket for overhead camshaft engine - has greater thickness adjacent cylinder bore than cam shaft drive
Inventor: BRUEGGEMANN HANS
IPC: F16J15/08
Filed: 1973-10-09
Abstract: The gasket is intended for engines wherein the cylinder head bolts adjacent the cylinder bore and those near the cam shaft are of different size and require different torques to tighten them. The gasket has cut-outs for the cam shaft drive and for the pistons and cylinder head bolting. The different thicknesses of the gasket when new, compensates. The reduced thickness may be achieved by compression prior to use. There may be a gradual transition between the portions of different thickness. Usually, cylinder gaskets have the same thickness and in mounting a difference in the pressing together results from the different starting torques of the bolts. A strain or distortion results between the dividing surfaces. This strain is usually carried over to the cam shaft and causes a heavier turning moment. The invention prevents this happening.

Title: Fibre pulling furnace - has pulling weight suspended in viscous fluid and heating input control by pulling speed
Inventor: NATH GUENTHER DR
IPC: C03B37/025
Filed: 1973-10-19
Abstract: A fibre optical light guide is drawn from quartz glass, glass, sheathed or plastics by suspending a rod in a cylindrical HF induction heating tube, with a weight at the end. A constant fibre diameter is maintained between the tapered end pieces by letting the weight descend inside a cylinder with a viscous fluid. The rope joining the weight to the rod passes over a perforated pulley which controls photoelectronically the heating output of the HF generator for the heating coil. This results in a reduction of the scrap rate from 90% to 20%. The viscous fluid damps out speed fluctuations and the electronic control eliminates the long-term variations.

Title: Three-high roll stand for light or medium sections - consists of two separate halves held together by tie-rods
Inventor: BUSCH FRIEDRICH-WILHELM
IPC: B21B13/04
Filed: 1973-11-22
Abstract: In the roll stand, which can also be used for shaping profiles, the top and bottom rolls are housed in movable chocks with independent adjustment, whereas the centre-roll is mounted in fixed chocks. The top and bottom rolls are located in two separate U-shaped half-stands, with U-shaped windows in which the moving chocks are housed, and with long-stroke drives for check-adjustment in a vertical plane.

The centre chocks are provided with shoulders which fit into the two half-stands and either threaded spindles or wedges can be used for adjusting the top and bottom chocks. The arrangement results in a relatively light stand with a wide-range of roll-gap adjustment and rapid roll change.

IPC: B22D11/126
Filed: 1974-03-13
Abstract: A machine for the impulse cutting (explosion cutting) of continuously-cast billets, has two shear knives with one knife moving towards the other. One knife is mounted on the piston rod of a cylinder, the cavity of the cylinder being in intermittent contact with a combustion chamber, whereas the second knife is mounted on a traverse connected to the cylinder housing. A floating sleeve is located round the piston rod and rests on the outer part of the piston, both the piston and the rod being provided with channels so that when the explosion occurs, pressure is exerted on the base of the sleeve. Both the top of the sleeve and the underside of the bolster are pref. provided with projections which clamp the billet during the explosion and shearing. Used for cutting continuously cast steel billets. By clamping the billet on both sides of the shearing point, no axial motion is imparted to the two cut portions which might disturb the process e.g. by raising the bath level in the mould.

Abstract: Parent Patent discloses a process for continuous addn. of 1-12 moles ethylene oxide and/or propylene oxide to a cpd. contg. >=1 active H, in a heat exchanger-surrounded spiral tube reactor, under pressures at which reaction mixt. is liquid, in presence of alkaline-reacting catalysts. Reaction takes place at 190-240 degrees C, kept constant over tube length. Peak temps. in 1st half of reactor are =30 degrees C above inlet temp. and =240 degrees C. Ratio tube length:tube dia. is 105:(1-10). Tube length is 100-160m. and reaction mixt. is passed through at 20-60kg/hr. In present Patent of Addn., the reaction mixt. leaving the reactor is continuously monitored spectrophotometrically.

Hazard of explosion through free alkylene oxide in presence of catalysts can be prevented. Plant can be operated without supervision, and can be switched on again, by hand or automatically, with a slight rise in reactor temp., for alkylene oxide-free prod. generation.

Title: Dewatering roll press - for the production of fibre webs thicker than paper e.g. cardboard
Inventor: KRETZSCHMAR WERNER
IPC: D21F3/08
Filed: 1975-03-21
Abstract: In a roll press for dewatering fibrous webs thicker than paper e.g. cardboard, in which the fibre web is moved between two felts or sieve-type woven fabrics through the press gap between the rolls, one of the press rolls has an elastic coating adapted to the geometry of the press gap in such a way that the gap constitutes a compression zone of length at least 60 mm in the presence of the two felts or sieve fabrics, and the upper felt or sieve fabric is guided in such a way that it runs into the press gap in an upwardly sloping direction. Enables a high compression to be exerted on the fibrous web for a sufficient time as it passes between the two rolls of a roll press to ensure intensive mechanical dewatering of the web.

Title: Anti-burst end hoods for nuclear pressure vessel - have compressible packings to accommodate slow temp. movements
Inventor: DAUBLEBSKY PETER DR
IPC: G21C9/00
Filed: 1975-05-17
Abstract: An anti-brust device for a nuclear pressure vessel consists of top and bottom hoods enclosing the end domes of the vessel, a set of articulated thrust rods bearing against each hood at one end and against a support ring at the other end, and a vertical stressing system of tie bars or the like connecting the two support rings together along the axis of the vessel. At one or more load transmission points between hood and vertical tie-bars there are packings of a material which deforms plastically under a gradually increasing load but behaves rigidly under sudden impact loading. The pref. material is lead. Used as anti-burst device for a nuclear reactor vessel. The use of gradually compressible packings enables the system to be set up without leaving any clearance to accommodate thermal expansion. Thus, if a burst occurs at an early stage, there is no gap in which ruptured components can accelerate.
