Patent DE-2042546-A1 (DE)
Title: Reduction of cooling of continuous castings - in secondary cooling zo
IPC: B22D11/12
Filed: 1970-08-27
Abstract: The cooling of continuous cast profiles in the sec. cooling zone is slowed down by the provision of coaxial thermal screens and heaters which act either directly or via the screen on the cast section. Pref. insulation may be given to certain parts of the surface such as e.g., the corners of rectangular profiles. The method prevents thermal cracking of the corners of rectangular profiles and also permits closer control of the solidification process as a whole.

Title: Leaf type suction valve for reciprocating compressor - has unloading stem through cylinder head to depress leaves
Inventor: LUTZ ROLF
IPC: F04B49/24
Filed: 1973-11-19
Abstract: A reciprocating piston moves in a cylinder at the top of which is a valve seating ring. The ring has radial slots each of which is covered by a leaf fixed at the outer edge and free in the centre. One half of the leaves deflect inward forming the suction valve and the other half deflect outward forming the discharge valve.

Title: Heat engine with rotary output - is driven by sequential expansion and contraction of wires under tension
Inventor: HAEBERLE WILHELM
IPC: F03G7/06
Filed: 1973-12-05
Abstract: The engine has a stationary shaft which carries a tapered sleeve at each end. Each tapered sleeve supports a bearing on which revolves a disc which is inclined to the stationary shaft because of the taper of the sleeve. The discs are joined to each other by wires so that the discs and wires form a cage like structure. The two discs are displaced circumferentially with respect to each other so that the wires are curved helically. The lower part of the cage is immersed in hot water and the upper part is exposed to cold air. The resultant contraction and expansion of the helical wires produces thrusts on the inclined discs which cause them to revolve.

Title: Electric furnace without lateral and/or frontal walls - holds charge in form of a mound, esp. for silicon carbide prodn.
Inventor: WIEBKE GUENTER DIPL CHEM DR
IPC: H05B3/60
Filed: 1973-12-21
Abstract: In a process for prodn. of SiC from sand and coke in an open top furnace in which current is produced via carbon electrodes and the resistance of the bed of matl. produces heat to initiate the reaction. Considerable reduction in capital cost is achieved by elimination of lateral and/or frontal walls, by the use of wheeled vehicles for charging and discharging, and by the elimination of the need for a building to house the furnace. The furnace may consist only of end walls housing the electrodes. The charge is piled between the end walls in a natural mound. Alternatively, one end wall with an electrode is used, the other electrode being at the base of the mound, or no end walls are used, both electrodes being at the base of the mound. The furnaces may be charged and discharged by wheeled vehicles. The installation operates satisfactorily out of doors.

Patent DE-2428136-A1 (DE)
Inventor: PFAFF HELMUT DIPL ING
IPC: B21H3/02
Filed: 1974-06-11
Abstract: Screw which taps its counter-thread and has a frustoconical shank end (4) which is provided with an odd number of, but at least three, oblique surfaces (5) which are distributed uniformly over the circumference of the truncated cone, being, in the axial direction, the length of approximately three thread pitches, form, in cross-section through the truncated cone, a polygon with rounded edges, and extend in the axial direction approximately over five thread pitches. Said self-tapping screw also has a thread rolled out in solid profile over the entire threaded length. The decisive feature of the screw are the diameters, increasing in the transition region from the cylindrical shank (1) into the frustoconical shank end (4), of the envelopes about the crests of the thread and about the root of the thread in comparison with the corresponding diameters in the actual cylindrical threaded part (3). In addition, in the abovementioned transition region, the radii of the self-tapping threaded portions are, in fact, smaller than the corresponding radii of the envelopes of the thread. The invention further relates to a process for rolling the thread of the abovedescribed screw from a blank having the same shank diameter as that used to produce the corresponding standard screw. <IMAGE>

Title: Film strip insertion machine in pockets - extracts lowermost pocket from stack in hopper for spreading open
Inventor: WEBER KLAUS DIPL ING
IPC: B65B43/26
Filed: 1974-09-25
