Patent DE-2035045-A1 (DE)
Title: Sintering of hard powders - under pressure isostatically applied via pulverulent packing
IPC: B22F3/15
Filed: 1970-07-15
Abstract: Packing powder for the sintering of pulverulent hard materials under isostactic pressure consists of a material, which does sinter at the temp. applied. This method is superior in some respect to the use of a gaseous or liquid medium for isostatic pressure transfer as the cumbersome use of an envelope is not indispensable, and the pressure sintering can be influenced by the activators or reactants introduced into the pulverulent packing. The latter pref. consists of C, SiC, Si3N4, BN or a mixture of carbon powder and a powder splitting off components of the hard material to be produced. It is used esp. to from practically non-porous TaSi2 sintered bodies.

Title: Carbon black mfr - from coke oven gas and coal tar vapours mixed with natural gas and petroleum vapours
Inventor: SUEW WIKTOR PAWLOWITSCH
IPC: C09C1/50
Filed: 1971-07-29
Abstract: A mixt. of coke over gas mixed with 0-50 vol.% natural gas is saturated with vapour from a mixt. of coal tar oil with 0-50 vol.% low-aromatic petroleum distillate is burnt, in the diffusion flame of a batswing burner with an angle between the burner and the adjacent carbon black deposition surface of 0 degree-45 degrees or 45 degrees-90 degrees. With an angle of 0 degree a black is obtained which can replace channel black, while with 90 degrees angle, a high quality active furnace black replacement is obtained. The blacks are suitable for use in rubber (e.g. tyres) and paints. Efficiency of the process and quality of the blacks are improved by the addition of natural gas and petroleum distillate.

The material, partic. for holding the rods in place, may be neutron absorbing.
Patent DE-2336862-A1 (DE)
Title: Wall calendar with daily tear-off sheet - convenient size using only 62 sheets
IPC: B42D5/06
Filed: 1973-07-19
Abstract: Each sheet of the calendar is divided into six equal parts by one vertical row and two horizontal rows of perforations. Each of the small rectangles carries the same number but represents a different month. Thirty-one sheets which are uppermost indicate the months January to June and another thirty-one sheets underneath indicate July to December. The sheets are separated by an intermediate sheet and fixed in a binder attached to a backing sheet and hung on the wall by a string. The arrangement of the calendar permits a readily visible date and at the same time the reduced thickness makes it easier to send through the post.

Patent DE-2347996-A1 (DE)
Title: Fixing metal soaps in mortars - aided by metal salts of short chain fatty acids
Inventor: GRUNAU EDVARD B DR RER NAT
IPC: C04B28/02
Filed: 1973-09-24

The salt, which may be that of an alkaline earth metal, Al or a rare earth metal with a 1-3C fatty acid, prevents the soap from migrating to the surface without reducing its surface adhesion and is appreciably cheaper than resin dispns. (ca. 90% in the case of Ca formate).

Title: Low consumption high efficiency hydraulic motor - has vanes with sealing vane to provide maximum volume of medium
Inventor: BERTRAMS JOSEF
IPC: F03C2/30
Filed: 1973-12-17
Abstract: The vanes with sealing vanes provide a maximum volume in the delivery chamber in order to limit the consumption of pressure medium. The vanes divide the delivery chamber into a high pressure and a low-pressure chamber. The motor comprises a stator, rotor, vane and ring which move in the enclosed housing and are set against a pressure bearing or inclined bearing. During operation of the hydraulic motor the pressure medium, e.g. oil, can flow under pressure through the rear part of a carrier bolt to the delivery chamber and then through a further borehole in this to the low pressure chamber.
Patent DE-2402271-A1 (DE)
Title: Analogue-digital converter - converts analogue signals into binary signals in the gray code for high resolution radar stations
Inventor: BOEHM ALWIN
IPC: H03M1/00
Filed: 1974-01-18
Abstract: The converter error is compensated by one or several circuits operating in steps, using as test signal zero potential or a bipolar stepped voltage. Output signals are after processing and storage in the error correcting circuits subtracted from the converter input or output signal. The converter gain is 1, for the first stages and 2 for the remainder. Each converter stage has two symmetrically arranged emitter followers as a second differential amplifier operating as a self-controlled full wave rectifier. The stages may be externally controlled through comparators whose logic output level depends on the polarity of the preceding stage analogue output voltage. Emitter follower stages have as a common emitter resistor a current source with a high differential internal resistance, thus representing very accurate voltage amplifiers.

Title: Roller shutter take-up spool with polygonal hollow cross section - protruding longitudinal edge is fitted with slots parallel to spool centreline
Inventor: MAEULE EWALD
IPC: E06B9/171
Filed: 1974-02-01
Abstract: The spool can be used for taking up the shutter sheet or as reel for textile sheets. The protruding longitudinal edge is created by doubling over the sheet metal and the longitudinal slots punched through this extruding edge serve as anchorages for the threaded-on ends of the shutter or textile sheet. The slots are arranged with their bottom edges flush with the surrounding surface of the polygon. The number of slots is arbitrary, the gaps between the slots are equal. When using for anchoring the strap of a roll shutter the ends of the strap can be held in place by depressing the exterior slot edge and hereby pinching the threaded-through strap end.

Title: Bird-box with gabled roof and lower box - with roof and one gable in one piece slotting over trough and other gable with hole in
Inventor: MEYER RUDOLF
IPC: A01K31/14
Filed: 1974-04-24
Abstract: The inside lengthwise side f the roof eaves has slats forming a dovetailed joint, together with projections on the underneath box which slots into it. The lower box has a floor and four walls which open conically outwards to form a trough. The projections extend into two opposite walls. A gable end is in one piece with a third wall and has a hole in it formed of a semi-circular aperture at the top of the gable wall. The roof opposite the gable wall joined to the underneath box projects forwards, as a protection against cats. The bird-box is screwed to a tree or wall through a hole in the back gable wall; the axis of the screw hole coincides with that of the bird-entry hole. The size of the hole can be varied by inserting and removing a ring. Threaded sockets on the roof slats accessible from below are for screwing in screws which press against the projections of the underneath box.

Title: Surrounding frame for window - has movable flange permanently pressed against window and held by parts in profile
Inventor: HESS HERBERT
IPC: E06B1/30
Filed: 1974-05-08
Abstract: The frame can be adjusted to various wall widths and provides a sound seal. It can be lacquered in the factory ready for assembly and consists of two parts which overlap in the frame profile. A movable sealing flange is guided in grooves and is held permanently pressed against the door or window by e.g. spring pressure. A plate (3) is attached to the parts (1, 2) and this produces a pocket which serves as a guide. The plate may have counter hooks which improve the grip in the part (1). The frame can be made of any desired material. The system reduces the different sizes of frames required for the various widths of the walls and also achieves a more effective sealing.

Title: Automatic wire insulation stripping device - has knife edges moved by guides and and mounted in radial slots on cylinder coaxial with wire
Inventor: HAHN ADOLF
IPC: H02G1/12
Filed: 1974-07-17
Abstract: The wire insulation stripping device has knife edges (20) sliding radially or pivoting about axes parallel to the wire axis and mounted on a cylinder (9) that rotates concentrically with the wire. The cylinder has guides (10a) that m move relative to the knife edges such that they impart a radial shift and pivoting motion to the knife edges. This knife motion, resulting from the motion of the guides, is chosen to suit the thickness of the wire insulation. The knife edges are mounted in radial slots in the cylinder. The device is fully automatic and the process of wire stripping is greatly facilitated.
