Title: Embossed prods. or contoured metal sheet articles forming appts. - uses rollers for producing sinusoidal corrugations which have end faces inclined to plane of rotation
Inventor: KLEIN KARL
IPC: B21D13/04
Filed: 1978-11-21
Abstract: Corrugations, which follow a sinusoidal line in the longitudinal direction, can be rolled into sheet metal by means of a pair of rollers. The rollers are mounted in a frame on two shafts which carry mating gears. The rollers have end faces which incline to the plane of revolution. The upper roller has a circumferential groove on one edge and a ridge on the opposite edge. The lower roller has a conjugate profile so that when the rollers rotate two sinusoidal lines of corrugations are produced in the sheet which is fed between the rollers.

Title: Encrypted digital communication between mobile subscribers - uses relay station which inserts synchronising sequence into messages
Inventor: KUKLA HUBERT F
IPC: H04L7/00
Filed: 1979-10-25
Abstract: Mobile subscribers in a radio net are in frequency duplex communication with each other via a relay station. Encrypted digital transmission is used and all subscribers have their own encryption/de-encryption unit. These units are synchronised by a central synchroniser in the relay station. Each transmission sent by a mobile (a) consists of a message (N) prefixed by a synchronising preamble (P). The relay receives the transmission and re-transmits it (b) with the first half of the preamble (P') unchanged, but with the second half replaced by its own synchronising sequence (SYN). When a subscriber is synchronised, the two halves of the preamble, sent by the relay, contain the same synchronising sequence but displaced by the propagation time between subscriber and relay. This information enables subscribers to allow for propagation delay when de-encrypting received messages. Each subscriber has a stable oscillator to maintain synchronisation during interference.

Patent DE-2949976-A1 (DE)
Inventor: WALLIMANN HUBERT
IPC: H01H35/24
Filed: 1979-12-12
Abstract: The pressure relay allows the monitoring of its sensor (2), which responds to pressure, by means of a calibrating manometer (21) which is temporarily connected to the same measurement space (3, 3'). The measurement space is continuously separated from the operating space to be monitored, by means of a shutter (7) which is provided with a small opening (4). For monitoring, the pressure in the measuring space is varied by opening and closing a vent nozzle (24) which opens into free space and whose cross-section is larger than the shutter opening. The small gas quantities which are required to build up the pressure in the measurement space flow through the shutter opening from the operating space into the measurement space. <IMAGE>

Title: Solid fuel low-emission firing system - uses fire-box separate from storage chamber for fuel
Inventor: MOHRHAUER PAUL DIPL CHEM DR
IPC: F23L1/02
Filed: 1980-02-06
Abstract: The firing system for a stove or boiler (100) gives low-emission combustion of solid fuels, the firebox (1) and the storage chamber (5) for the fuel being separate from each other. The fuel can be arranged to be fed to the firebox periodically in small quantities, and combustion air can be delivered both above and below the grate, the controls for air and fuel supply being interlocked. The quantity of air delivered above the grate can be such that the fumes from the firebox contain free oxygen. The design avoids heavy smoke emission due to sudden stoking with large quantities of fresh fuel.
Patent DE-3004487-A1 (DE)
Title: Double exposure control for cine camera - has electronic programmer with frame counter and timer for reversing film drive
Inventor: ROTH JOHANN ING GRAD
IPC: G03B19/18
Filed: 1980-02-07
Abstract: A double exposure control for a cine camera has an electronic programmer which determines the amount of film run off with the decreasing exposure and rewinds the film automatically for the start of the next scene, which is taken with increasing exposure. The film lengths are determined by timing circuits as well as frame counters and decoders. The double exposure effect merges successive scenes and is operated fully automatically. The control is applied to a sound cine camera by inhibiting the sound head during the rewind. The next scene is inhibited until the light and sound levels reach set min. values. Different lengths of overlap can be programmed without altering the exposure control of the camera.
Patent DE-3004912-A1 (DE)
Title: Hydraulic support system for bottom calendar roll - combining external jacks and internal support pistons under central control
Inventor: PAV JOSEF DR ING
IPC: D21G1/00
Filed: 1980-02-09
Abstract: In a calender machine with a vertical stack of at least two rolls, of which the lower roll comprises a vertically-movable, cylindrical shell carried on a central shaft by hydraulic support devices which can compensate for bending of the roll, the shaft is carried in bearings mounted on hydraulic jacks which raise the bearing assembly against fixed stops to hold the roll in a defined working position. For rapid separation of the calender rolls, the hydraulic control system has a device which simultaneously opens the outlet valves of both the cylinder support system and the bearing support jacks. The valves close at different times in order to arrest gently the motion of the roll. This construction allows the stroke and the speed of the internal cylinder support pistons to be reduced, giving less piston/cylinder wear and a longer working life between major overhauls. It enables the speed of roll separation to be increased without creating damaging shocks to the roll during its arrest.

Title: Laminated magnetic core for low inductance choke coil - is divided into two parts including air gap and lacquered joint
Inventor: WAASNER BRUNO
IPC: H01F3/14
Filed: 1980-03-06
Abstract: The magnetic core for the windings of a choke coil is made from a stack of laminations, divided into two sets so that the core can be inserted into the windings.

The two sections (6,7) are also divided by an air gap (11) at the top of one outer limb and by a joint (17) at the bottom of the other limb. This joint can be lacquered. The air gap can have a rivet shaped securing member (10) connecting the two sides, made of non-magnetic material. The core is intended for coils of lower inductance, and this may be reduced by 25 to 50 per cent, pref. more than 50 per cent. Alternative constructions include a core with one opening only, enclosed by a rectangular core.

Title: Removal and assembly jig for blast furnace tuyeres - has simple by reliable design and can be mounted on standard forklift truck
Inventor: STEINKUEHLER ALOIS
IPC: C21B7/16
Filed: 1980-05-09
Abstract: The jig comprises a vehicle on which a horizontal plate can be adjusted vertically. On the plate is a vertical pivot for a horizontal frame which can be swivelled through 360 deg. and carries a hydraulic or pneumatic hammer used to exert force on a traverse. The traverse is joined by two tie rods to a coupling plate with claws, which can be located behind lugs on a tuyere. Hammer blows on the traverse loosen the tuyere so it can be drawn out of a blast furnace. To fit a new tuyere in the furnace, the horizontal frame is rotated 180 deg., so the hammer and coupling plate can push the tuyere into the furnace casing.
