Patent DE-2630853-A1 (DE)
Inventor: CHINIARA CAMIL DIPL ING DR
IPC: D21F5/20
Filed: 1976-07-09
Abstract: Supply air is fed, via an inlet line (3), to a housing (1) for the material to be dried. The moist discharge air is led away via an outlet line (4). The condenser (6) is connected in the inlet line and the evaporator (10) of a heat pump (7) is connected in the outlet line. By transmitting the heat of the discharge air to the supply air by means of the heat pump, the heating cost and the damage to the environment by waste steam are reduced. The apparatus is particularly suitable for the dryer parts of a paper machine. <IMAGE>

Title: Trajectory electromagnetic control system for projectile - applies correcting force on computing deviation by propellant charge or spoilers
Inventor: SIEBECKER HANS DIPL ING DR
IPC: F41G7/30
Filed: 1976-12-22
Abstract: The trajectory of the projectile provided with combined optical and electronic equipment is corrected by an electromagnetic system. The deviation data are fed into a computer for evaluating the point of time for correction. The connection beam to the projectile is modulated if necessary. A specified force is applied at right angles to the instantaneous direction of flight and at a precomputed angle to the plane of the trajectory at the centre of gravity of the projectile. After this first correction the angular position of the projectile relative to the required trajectory is evaluated. A second correction pulse is automatically triggered if the deviation relative to the required trajectory is increased. The specified force is generated by propellant charges, correction nozzles or the extending aerodynamic spoilers.

Title: Location brackets on cupboard door - has insert which prevents transport damage to kitchen furniture
Inventor: DOEPKER HEINZ
IPC: E06B7/00
Filed: 1977-02-24
Abstract: A location bracket (30) which protects kitchen furniture from transport damage, is placed over the free edge of a hinged door (9). The wall thickness (33) of the U-shaped bracket equals the gap between the door (9) and the adjacent cupboard wall (3), and which is produced by the door damper insert (27). A right angle extension (38) on the bracket is located against the inside of the cupboard wall (39). It absorbs any transverse load (A) that might occur on the cupboard door (9) and thus prevents its hinges from being damaged. Similar brackets, and for the same purpose, are installed on the hinged door edge.

Title: Rockwell type hardness tester - having mechanism to amplify relative movement between test surface and pressure tip
Inventor: ERNST ALFRED
IPC: G01N3/44
Filed: 1977-02-24
Abstract: Rockwell type hardness tester has an upper section which contains a member to accept pressure from outside and which carries a loading spring. The lower section has a reference surface and the pressure tips together with a mechanism to magnify the relative movement between these. It has intermediate parts between the loading spring and the tip by means of which the upper and lower parts can be pushed together by an outside force between a rest posn and a stop. The spring is subjected to a constant deformation transmitted as a constant load. The excess pressure brought down is carried by the reference surface. Used in measuring metal hardness on the Rockwell system. Provides method with simple up and down motion where only the reference surface and the tip need be moved. The test pressure remains constant even if the applied pressure varies, and this test pressure can be adjusted in a wide range.

Title: Perspective correction of photographs - uses montage method to provide correct representation of building facades and roofs
Inventor: KOHLHOFF SVEN
IPC: G03B15/08
Filed: 1977-03-29
Abstract: The photographic montage method is for perspective correction for building facades so that the front wall and the sloping roof area are represented in correct proportion even though the original picture was taken from street level. It is intended for quick production of building facades of correct perspective which can be used for illustrations, e.g. books, illustrated town maps, and look as though taken directly from the front at the building mid point height. In a narrow street (26), a photographer (at 31) with perspective control facilities on his camera will still have a misrepresented roof area (39) in the final photograph although the verticals are correct. The method is to replace the roof area on a montage and rephotograph to produce the final print.

Title: Tubular chuck for holding round bar - has row of interlocking spherical rings with tongue extensions which grip workpiece
Inventor: AUSTIN RICHARD ARNOLD
IPC: B23B13/12
Filed: 1977-07-27
Abstract: A chuck for gripping round bars or tubes consists of an outer tube (10) which houses a number of rings (30, 40). The rings have spherical outer surfaces and pivot inside the tube on two diametrically opposite bolts (34). These rings also have two diametrically opposite tongues (32) aligned at right angles to the bolts and projecting in axially opposite directions. The rings (40) have cylindrical outer surfaces with a single tongue (42) and are attached by screws through slots in the wall of the tube to a rod. The rod is moved axially by a pair of nuts screwed on the end of the tube. This axial movement of the rod brings each cylindrical ring closer to its neighbouring spherical ring, causing it to rotate about the pivot so that the tongues grip the internal bar.

Title: Bullet hole deflection measuring equipment - uses light reflected from target onto photoelectric cell to generate alternating voltage
Inventor: HOSP FRANZ
IPC: F41J5/16
Filed: 1977-10-18
Abstract: The mechanism measures the deflection of the bullet hole from the centre of a target, having a plate rotated by an electric motor and of transparent material, with a centering mandrel for the bullet hole. The target is laid against the plate, below which is a light source. The light is reflected from the target onto a photoelectric cell detecting the amt. of eccentric movement of the target mirror edge. The alternating voltage generated during target rotation (7) as the result of the balance of light and darkness at the photoelectric cell (10) is passed if necessary through an amplifier with interference suppression, and fed to an electronic digital indicator (14) evaluating the amplitude of the alternating voltage. The figure shown represents the degree of accuracy of the shooting.

Patent DE-2911182-A1 (DE)
Inventor: ROTH ANTON DR
IPC: E04H6/22
Filed: 1979-03-22
Abstract: Disclosed is a lift-type car park for removably storing a plurality of wheeled motor vehicles. The lift platform has a telescoping transport device mounted thereon. The lift platform can be brought level with a transfer area and the telescoping transport device can be extended adjacent the wheels of the motor vehicle to be parked. Guide rollers can then be swung out from the telescoping transport device to movably engage the wheel such that when the telescopic transport device is retracted onto the platform the motor vehicle is pulled onto the lift platform as well. The lift platform can then be moved to any one of a number of storage locations and the reverse operation takes place in which the motor vehicle is placed in a storage space. As a safety feature, in the area where a car is initially picked up prior to storage or deposited after storage, the telescoping transport device extends into a tunnel which serves as a walkway for vehicle occupants protecting them from the telescoping transport device and the guide rollers mounted thereon.
