Patent DE-3311270-A1 (DE)
Title: Cutting device for automatic cutting of a protective film web continuously laminated onto consecutive workpieces of the same thickness and width and any desired length, in a manner exactly coinciding with the mutually adjacent edges of the aforementioned workpieces
Inventor: JOHANNSEN HANS PETER DIPL ING
IPC: B26D1/04
Filed: 1983-03-26
Abstract: The problem exists in practice of cutting protective film continuously laminated onto individual workpiece formats between the formats. The cutting carried out according to prior known processes with film sections projecting over the workpiece edges on both sides of the cutting point leads to difficulties in further processing. According to the invention this problem is solved in that the cutting device - a roll, sphere or spring steel tongue - can freely adjust to the position of the workpiece edges. If this cutting device is then pulled through the gap under slight pressure it uses the two workpiece edges themselves as counterparts to two pinch-off lines. The film is pinched off directly at the workpiece edges with extremely low forces and cut out as strips. The workpieces are supported from below only at the instant of cutting so that damage during the further transport is eliminated. The process is suitable for cutting with halting of the workpieces but also for flying cutting without halting.

Title: Safety device for a hydraulic downstroke press
Inventor: MOELDERS HEINZ
IPC: B30B15/28
Filed: 1983-05-28
Abstract: The press consists of a static bottom tool with the bottom die half and a top tool performing a stroke movement and having the top die half. An actuating button for initiating a program-controlled work cycle of the press is located at a safe distance. In order to eliminate the possibility of the top tool falling down and endangering the operator through defects in the drive or in the mounting, it is proposed to provide a toothed rack on the press, which toothed rack runs parallel to the stroke path of the top tool and has a saw-tooth profile, and to pivotably mount a pawl on the top tool. This pawl is reversed by a servomotor between a distanced position and a contact position with regard to the saw-tooth profile. In the event of a defect, the pawl catches behind a steep flank of the saw-tooth profile and swings out completely so that it rests with a shoulder on an end stop on the top tool.
Patent DE-3320282-A1 (DE)
Title: Bird cage
Inventor: VOSS JOSEF
IPC: A01K31/06
Filed: 1983-06-04
Abstract: The bird cage consists of a wire basket (1) and a plastic tray (10). In the condition of use, the wire basket is placed on a shoulder of the tray and connected thereto by easily releasable members. Since the wire basket substantially retains its ground plan towards the top, whereas the tray has a ground plan which becomes increasingly smaller towards the bottom, the possibility exists of reducing the space required for transportation and storage by placing the wire basket on the shoulder of the inverted tray. By means of webs moulded onto the tray which rest on an inner terminal wire of the wire basket, the tray and the wire basket are fixed relative to one another during transportation. <IMAGE>

Title: Process for biological waste water treatment with elimination of nitrogen
Inventor: BOEWE WOLFGANG DIPL ING
IPC: C02F3/30
Filed: 1983-08-05
Abstract: The invention relates to a process for the biological treatment of waste water, carbon compounds and nitrogen compounds being controllably degraded in a combined tank without partitions. By process engineering techniques, the tank is divided into an aerated region, the nitrification zone, in which carbon compounds are degraded and ammonium nitrogen is oxidised to nitrate, and an unaerated region, the denitrification zone, in which nitrate is reduced to elementary nitrogen. In the tank, which has longitudinal flow, the denitrification zone is located in the forward tank section and the nitrification zone is located in the rear tank section. Activated sludge required is returned both from the secondary clarification and also from the outlet of the nitrification zone. The air input over the longitudinal profile of the nitrification zone can be controlled.

Title: Ink-ribbon cartridge for a typewriter or office machine of similar design
Inventor: BEHRENS ROLF ING GRAD
IPC: B41J32/00
Filed: 1985-07-05
Abstract: Ink-ribbon cartridges for typewriters or office machines of similar design are subject to different construction requirements, the intention being above all for them to be easily exchangeable by means of single-handed operation. Since, in such cartridges, the transporting elements, for example for the carbon ribbon, are also mounted in the cartridge housing, these cartridges are very expensive. Since, furthermore, the ink-ribbon cartridges are designed to be disposable parts, many still functional individual parts are also thrown away. The invention is based on the object of providing an ink-ribbon cartridge having a carbon ribbon, which cartridge can be inserted in and removed from the receiving device of the machine by means of single-handed operation. Additionally, exchanging the ink-ribbon reels by the person operating the machine is to be possible at any time without particular dexterity. Above all, the disposal of material in each ink-ribbon exchange is to be reduced considerably compared to current handling. This object is achieved in that the receiving reel (14) with the carbon ribbon (12) can be moved by an actuator in the cartridge housing into a lockable disengaged position with the pin wheel (37) of the feed roller (38), in that the feed reel (13) and the receiving reel (14) are mounted rotatably on a removable part (3) of the cartridge housing, and in that the part is constructed as a mounting tool for exchanging the ink-ribbon reels (13, 14).

Patent DE-3524641-A1 (DE)
Title: Shell-type case with a character input unit
Inventor: MAURUS GEORG
IPC: E05B49/00
Filed: 1985-07-10
Abstract: Attached to the outside on a shell edge of a half-shell is a compact strip which is provided with a keypad, with an electronic lock control, with coding switches and with a locking device. The locking device has, at the plurality of locking points, locking levers which can all be jointly actuated by means of a single rotary operating knob. In the closed state, the locking device or the rotary operating knob is blocked by a lifting magnet. Release takes place only when a number code preset via the coding switches is input into the keypad. The design of the strip, together with the components arranged in it, has the advantage that the case wall does not have to be provided with perforations and recesses which are usually necessary for attaching these parts. The strip itself can be attached by relatively few fastening means. The case is therefore sealed off very effectively.
