Title: Fibre baling press with wrapper positioning arrangement - for hooping bales directly in the press without circumstantial manipulation
IPC: B65B27/12
Filed: 1979-10-10
Abstract: Rectangular sheets of wrapping material are laid on to the two pressing plates opposing each other in a fibre baling press, and after the baling operation, the sheets are pulled over the bale and are held in place by straps or wires, etc. Carrier is first of all covered on both sides with the sheets of wrapping material which are then pressed over the pressing plates. Each sheet is held on the plate by four clamps, and after pressing is drawn over the bale, the one sheet overlapping the other. Fibre baling press having at least two mutually opposing pressing plates and an arrangement for wrapping and hooping the pressed bale according to the procedure outlined, has a mobile carrier. With this, the pressing plates are covered with the wrapping material which is held in place by clamps. Carrier has a passage through it. The daylight of which is greater than the cross-section of the pressing plates. It can be moved from a position outside the working zone of the press into a position between the pressing plates and be tilted over them. Each pressing plate has four clamps for the packing material arranged on the side of the plate turned away from the bale. Each clamp consists of a pivoting arm with a telescopic section and a jaw at its free end. Carrier can be tilted horizontally and vertically. It has the form of a box as deep as the thickness of the pressing plate. The wrapping material is held in place by suction.

Title: Camera for intermittent observation of molten weld pool - where high speed camera shutter is formed by electro=optic ceramic disk made transparent by voltage pulses
Inventor: SCHOENER VOLKMAR
IPC: B23K9/095
Filed: 1979-12-15
Abstract: During an arc welding process, a controllable welding transformer (6) is used for periodic interruption of the welding current. A camera is aligned on the molten weld pool, and has a shutter (12) which is synchronised with transformer (6). Shutter (12) is either an electro-optic ceramic disk, or a Kerr cell, the transparency of which is influenced by a voltage. The pref. appts. includes an electro-optic ceramic disk (12); and a phototransistor (13) used as an opto electric transducer is located between the weld pool and disk (12). The phototransistor (13) triggers a square-wave generator (15) which provides pulses making disk (12) transparent when the welding pulses provided by transformer (6) approach zero voltage. The invention improves and simplifies the camera appts. described in 2651878.

Patent DE-3014449-A1 (DE)
Inventor: KASPER GEORGE PHILIP
IPC: G03G5/14
Filed: 1980-04-15
Abstract: The image quality obtainable by an electrographic copying process in which an electrostatic latent image formed by imagewise exposure of a uniformly charged photoconductive layer, or otherwise, is developed with a toner can be improved if the latent image comprises discrete charge bearing zones, preferably formed by a supplementary exposure through a half-tone screen, and if additionally the toner is electrically conductive either intrinsically or as a result of electrical break-down. In this manner, the maximum density obtainable in a copy can be increased and the contrast decreased sufficiently to allow good reproduction of both continuous tone and high contrast images.

Title: Forming wiring pattern on acrylic! glass plate - by printing waterproof adhesive on copper foil bonded to carrier with soluble adhesive, etching and transfer
Inventor: HAERTING WOLFGANG
IPC: H05K3/00
Filed: 1980-12-06
Abstract: In the application of electric wiring patterns to acrylic glass plates, esp. floodlight plates, a Cu foil is bonded to a stainless steel or plastics carrier plate with a water-soluble adhesive. An activatable, etching-resistant and waterproof synthetic rubber-based adhesive is screen printed on this Cu foil in the required pattern and, after the adhesive has dried, the unprinted Cu foil is etched away from the carrier plate. The wiring pattern is then transferred to the acrylic glass plate by activating the second adhesive with a solvent or by direct or capacitive heating and the whole is placed in water to dissolve the water-soluble adhesive, until the substrate plate can be lifted off. Di-ficulties of obtaining the required adhesion encountered in relatively costly electroplating processes are avoided.

IPC: B02C13/13
Filed: 1980-12-08
Abstract: The mill with raw material feed (21) has an extract line (51,52) for the fraction which does not pass through the sieve (33). The extract line leads, pref. via a cyclone (53) with cell wheel discharge (55), onto a vibrating sieve (44). From this sieve the coarser material, not passing this sieve, is discharged at an overflow (45) to combine with the material entering (23) from the hopper (21), while the finer material leaves to enter the fine material collecting space (11) around the sieve. Preferably, the raw material from the hopper is fed into the inlet duct (23) from a vibrating tray (22), driven, together with the vibrating sieve (44), by a common drive (42).

Title: Hammer mechanism for printer - has fixed yoke and armature to give magnetic field with two maxima
Inventor: HEIDER ULRICH DR ING
IPC: B41J9/38
Filed: 1981-04-24
Abstract: The hammer mechanism has that region of its stationary yoke and of its drive part that is largely responsible for the armature's (AK) axial drive force (KA) designed so that the axial drive force has two maxima (M1,M2) along the path travelled by the armature away from the end-stop (AS) to the point of impact. The two maxima are joined by a smooth curve.  The advantage lies in reduced size, lower excitation current and rapid return of armature after printing.  The armature is braked by a braking pulse in the region (ZB) between the two maxima during its return to its initial position.

Title: Flue gas scrubbing plant preferably downstream of coal power stations with gypsum production
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/50
Filed: 1981-05-30
Abstract: The invention relates to a process for flue gas desulphurisation with the aid of a scrubbing liquid which contains lime and/or calcium ions. Gypsum is obtained in this process and the calcium contained therein is replaced by addition of lime to the scrubbing liquid before the scrubbing liquid is reused for flue gas scrubbing. In this case the gypsum separation and lime addition are carried out in a gravity separator, in particular a jacketed sink separator. According to the invention, a further vessel is arranged between the scrubber and the gravity separator. In this vessel, lime is added to the scrubbing liquid so that gypsum crystals form there already. Some of the scrubbing liquid flowing out from this vessel is directly fed to the flue gas scrubber. As a result, the shape and the size of the gypsum crystals produced in the process can be influenced in such a way that a marketable gypsum is obtained.

Title: Process for producing coloured images by the dye diffusion transfer process, and recording material suitable therefor
Inventor: HELLING GUENTHER DR DIPL CHEM
IPC: G03C8/52
Filed: 1981-08-14
Abstract: The undesired image produced in the light-sensitive element and retained, in addition to the desired transfer image produced in the image-receiving layer, in an integral colour-photographic recording material consisting of transparent base, light-sensitive element, light-reflecting opaque layer and image-receiving layer, is removed from view, in order to improve the overall visual impression, by producing an intensive colouring, which effectively covers the undesired image, in an additional layer, for example an NC layer, located on the back by reaction of two reaction components, of which one is present in the additional layer in a state resistant to diffusion and the other is dissolved in a treatment bath. The additionally transparent layer contains, for example, a polymer latex loaded with heavy metal cations, and the treatment solution, for example a developer bath, contains an organic complexing agent which reacts with the heavy metal cations to form a metal-complex dye.
