Patent DE-2533797-A1 (DE)
Title: Straw walker for threshing machines, esp. combine harvesters - consists of two-level slatted platform with gaps for grain to pass through
Inventor: MIELCZAREK GUENTHER
IPC: A01F12/30
Filed: 1975-07-29
Abstract: The slatted straw-walker (1) is driven by crank-shafts mounted in the sides of the combine-harvester. The vibrating surface (5) of the straw-walker (1) is on two levels, so as to increase the grain-separating surface. The vertical pieces (6, 7) of the vibrating-surfaces (5) have gaps (8). Metal guide-plates (9) are fitted into these gaps. The bottom level of the vibrating surface (5) has larger gaps whereas the top level (11) has narrower gaps. This provides a more thorough separating of the corn.

Title: Constant temp. cylinders for e.g. calenders in textile or paper mfr. - using easily volatised oil condensing on outer cylinder
Inventor: JOHNSON JACK
IPC: F26B13/18
Filed: 1975-08-13
Abstract: The constant temp. is maintained by partially filling the annular space between the periphery of the cylinder and a second concentric inner cylinder with an easily volatilised oil, (b) pumping out of the annular space to a predetermined press. at atmospheric temp. and subsequent sealing of this space, (c) evaporating the easily volatilised oil at a temp. determined by the pressure in the annular space using a heating medium which is present between the wall of the second cylinder and a third inner most concentric cylinder. The constant temp. maintained on the outside of the cylinder can be predetermined by the press. above the oil in the annular interspace rather than by the supply of heat.

Title: Free wheel with spring loaded pivoted pawls - has drive transmitted through wedging action of convex faced pals
Inventor: BRAND FRANCIS
IPC: F16D41/07
Filed: 1975-11-14
Abstract: The free wheel transmits the drive from the outer member (P1) to the inner member (P2) when rotating in a clockwise direction. The pawls (6) have two parallel faces (7a, 7b) and two convex faces (8a, 8b). One convex face (8b) has a uniform radius of curvature while the other (8a) has a larger radius on the surface near the side (7a). The pawls are mounted on a spindle (5) supported between two side plates. A torsion spring (3) applies a force to the pawl tending to rotate so that the surface (8a) is wedged against the inner surface (P2). When the outer member (P1) is rotated clockwise this tendency is increased so that the drive is transmitted to the inner member (P2).

Title: System for increasing boiler overall efficiency - avoids higher furnace gas temperatures and consequent corrosion problems
Inventor: VEGEBY ANDERS
IPC: F22D1/36
Filed: 1975-12-19
Abstract: System for raising overall steam plant efficiency without severe air pre-heater corrosion problems, for variable steam loading, in which the gases from the furnace pass over the superheater and the air preheater. The intake air is first compressed by the compressor by up to 5 atm. before being passed through the preheater tubes, and energy extracted from it by expansion down to 1000mm of water in a turbine before passing to the burner. The turbine drives the compressor and an auxiliary generator. At low loading, excess air may be bled off to the water preheater. An alternative arrangement provides for high load factors.

Title: Toy model construction kit - contains interlocking building elements erected on screened construction plate
Inventor: HAUNSCHILD ERWIN ING GRAD
IPC: A63H33/10
Filed: 1976-02-25
Abstract: Combination construction kit is for the assembly of toy models, e.g. castles. The building elements and units are assembled on screened construction plates which are made as holed plates and are fixed to them and to each other by connecting bolts. The building elements are characteristic of a particular method or type of building and the screens of the construction plate correspond to the corner points of polygones having an equal side distance. The construction plates may be enlarged by adding further construction plates as required on any side and the holes of the construction plates are formed in such a way that they may be used on either side.
Patent DE-2613459-A1 (DE)
Title: Arrangement for avoiding scrap in a rolling mill - for wide strip material, during break down of the prodn. line and/or the strip winding arrangement
Inventor: ILLERT KARL
IPC: B21B1/26
Filed: 1976-03-30
Abstract: The raw material first passes through a row of pre-rolling mills. The pre-rolled strip is wound on rollers after which the rolls are placed by a transporter in an oven. The oven forms a store for several rolls of pre-rolled material and keeps these at rolling temp. during any break down of the finishing plant. The transporter is so arranged, that the rolls are turned over in a horizontal plane by 180 degrees. This ensures that the rolls leave the oven with the correct end facing the finishing plant. When the break down is repaired, the transporter removes the rolls from the oven and places them in the winding machine which in this case unwinds the rolls and feeds the material to the finishing plant.
Patent DE-2614160-A1 (DE)
Title: Continuously perforating matted fibre webs - using embossing cylinder heated to melting temp. and contact cylinder heated to softening temp. and differential speeds
Inventor: ENDLER HERIBERT

Title: Pressure limiting valve for hydraulic or pneumatic use - has resilient valve head to permit easy setting of pressure
Inventor: NERLICH ERNST-GUENTER
IPC: E21D15/51
Filed: 1976-04-07
Abstract: The valve body (4) is screwed into the wall of the pressure vessel (1). The valve head (9) which is made of spring steel, has a cylindrical extension (8) which forms a guide and slides in the bore (7). The other end of the valve head (9) forms a hollow cone (13) with a lip (14) which presses against the tapered bore (15) of the valve seat (14) which is made of plastic. The axial position of the valve head (13) is easily adjusted by the screw (22) which has a ball end (23) which fits inside the hollow cone of the valve head. Adjustment of the axial position of the head (8) adjusts the radial pressure between lip (14) and bore (15) and this, in turn, adjusts the valve opening pressure.

Title: Bidirectional drive for magnetic tape capstans - has idler gear mounted on pivoted beam moving between two positions when motor is reversed to switch drive from one capstan gear to other
Inventor: HERLETH KARL
IPC: G11B15/44
Filed: 1976-05-20
Abstract: A pivot-mounted idler gear is used to effect direction of rotation changeover in a tape cassette with a single motor drive unit. The bi-directional motor is mounted in a fixed position and transmits rotary motion (1) to one of two gears (3, 4) coupled to the drive capstans. An idler gear (2) is mounted on a pivoted beam (5) and has a simple spring clutch to provide light contact between a felt disc and the beam. When the motor gear (1) moves in one direction motion is transmitted to one capstan gear (4). Reversing the motor rotation causes the beam to move against another stop to cause the second output gear (3) to be engaged.

Title: Electrically-closed, spring-opened ironing machine - given extra gears, to make the spring more effective
Inventor: HOLLENBECK HUBERT
IPC: D06F67/10
Filed: 1976-09-09
Abstract: Parent patent concerned an ironing machine which closed against the action of a spring, when an electric motor moved a toothed segment with the aid of a worm gear. The machine was held closed by reduced motor current, and was opened by the spring when the current was broken. The spring was attached directly to the toothed segment, but this method has been found unreliable. In this addn., two extra gears, on a common axle are interposed between the worm gear and the toothed segment, and the spring now works via a cord wrapped round a pulley on the same axle. The complete travel of the toothed segment is now pref. equivalent to a full revolution of the electric motor.
