Patent DE-2701905-A1 (DE)
Inventor: STARK KARL-HEINZ
IPC: E04C2/08
Filed: 1977-01-19
Abstract: The extruded structural element has a flat centre web (2) and, on its longitudinal edges, in each case one integrally formed snap connecting element (3, 3') with a U-shaped cross-section. When connected to identically constructed, adjacent structural elements by pushing into one another, the problem arises of replacing a structural element - for example after a minor traffic accident - comparatively easily on a wall, which is produced from these structural elements, of a motor vehicle. For this purpose, the structural element (1) has on the inside of the limbs (5', 6') of the respective externally located snap connecting element (3') in each case one latching closure element (7', 8') behind which there engage latching closure elements (7, 8) which are integrally formed on the free edges of the limbs (5, 6) of the respective internally located snap connecting element (3). Since the webs (4, 4') of the snap connecting elements (3, 3') run parallel to the plane of the centre web (2), the snap connecting elements (3, 3') can be coupled by a movement directed at right angles to the plane of the centre web (2). In order to absorb forces in the plane of the web (4), a supporting surface (12'), which is open in the insertion direction, is arranged on the inside of that limb (6') of the respective externally located snap connecting element (3') which opens in the centre web (2), which supporting surface (12'), together with a supporting surface (12) which is provided on the respectively adjacent structural element, forms a tooth system in the connected state. <IMAGE>

Title: Magnetic tape cassette with tape position indicator - allows easy access to any part of tape and determines dia. of tape wound on spools to give position
Inventor: SAUERMANN KLAUS
IPC: G11B23/087
Filed: 1977-03-03
Abstract: A magnetic tape cassette is used in which the quantity of tape wound on one spool and off the other is indicated by a simple needle and scale indicator. Any required section of the tape can be accessed easily. The magnetic tape cassette (1) contains two spools each wound on a central core (2, 3). The quantity of tape on one spool decreases as that on the other increases, and this change of effective spool diameter is detected by an indicator needle (2) buffered by two springs (6, 7) which bear against the tape surfaces on the spools. The position of the needle (5) and so the position of the tape, is indicated on a scale (13) visible through a shaped window (11) on the front of the cassette. A number of slightly different designs for needle buffer springs are described.

Title: Ion focussing system for mass spectrometer - using nozzle entry to vacuum chamber and electric field reducing beam angle to reduce energy scatter
Inventor: FRENCH JOHN B
IPC: H01J49/10
Filed: 1977-05-14
Abstract: The ion focussing system, for a mass spectrometer's vacuum chamber, allows the gas from which the ions are derived to pass into the vacuum chamber via an aperture which causes the jet to expand freely outwards as at a nozzle. An electric field is generated near the gas/ion inlet such that the ions pass from a first region, which limits scatter in kinetic energy, to a second region in which the angle of the ion paths w.r.t. the axis passing through the aperture is less than that of the first region.

Title: Rotary filter with discs mounted on a shaft - has individually replaceable central filtrate removal chambers on shaft
Inventor: KANE ALFRED JOHN
IPC: B01D33/23
Filed: 1977-06-28
Abstract: Rotary disc filter has a long frame to which hollow segmental chambers are secured by reusable clamps spaced at intervals along the frame. A segmental chamber can be removed and replaced using the same clamp. The clamps can be maintained independently of the segmental filtration discs, which, in turn are attached to the segmental chambers. A pipe attached to the segmental chamber enables filtrate from the slurry to reach the segmental chamber from the filter disc. Another pipe connects one end of each chamber to a vacuum source to remove the filtrate from the chamber. The filter is of the type in which the discs are mounted on a shaft connected to a drive. As the shaft rotates, the discs revolve, their lower parts passing through a tank contg. the slurry to be filtered. The design of the filter minimises wear by the solids in the slurry, and when wear does take place only the worn parts need be replaced.
Patent DE-2729237-A1 (DE)
Title: Web length cutting machine - has stress equalising and storage track passing length sensing device at varying speeds
Inventor: KUNZMANN ANTON
IPC: B65H37/06
Filed: 1977-06-29
Abstract: The equipment is for cross cutting required lengths of paper from a roll, such as for instance a printed sheet, with subsequent folding operation. The cuts are carried out by the command of an optical sensing device reacting to markings on the continuous web. This is a roll(14) on a spindle(13) supported on a bracket(12). The web(15) after offcoiling from the roll passes a set of stress-equalizing and storage rollers(16) mounted on a swinging arm(17). The web is deflected by 180 degrees on these rollers and passes on to a second set of rollers(19). When the web has left the roller(19) it is further deflected by a roller(20) while passing in front a sensing device(21). Its signals operate the cutting roller(24) intermittently in conjunction with the periodically varying speed of the delivery roller(25). The varying speed is achieved by an elliptical gear(26, 27).

Patent DE-2735499-A1 (DE)
Title: Positioning system for pipe-laying vessels - uses anchors with winch control based on velocity components
Inventor: HOPPE DIETRICH DIPL ING
IPC: G05D1/02
Filed: 1977-08-06
Abstract: The automatic positioning system for pipe-laying vessels is based on a number of anchors which are connected via cables to winches. The winches are controlled by an automatic positioning unit so that the velocity components of the vessel in the direction of the anchor chain are used as a reference velocity for the anchor cable. This is provided by reference signals derived from the rotational speed of the winches. The winch drum set speed is weighted by a factor of less than one (typically 0, 5). This factor is selectable between zero and one. A stop control signal for the winch drums is derived from the sign sense of the drum speed, cable velocity and vessel speed. The winch drum speeds are limited by multiplication of all set speed values by a reduction factor which is chosen so that the winch with the highest set speed value attains the permitted speed.

Patent DE-2825800-A1 (DE)
Inventor: SCHAFER VICTOR
IPC: B65B27/04
Filed: 1978-06-13
Abstract: In the apparatus intended especially for aerosol cans, a row of cans of predetermined number, lying next to one another in axis-parallel manner, passes respectively on to a horizontal table (14), where the row is aligned by means of adjustable positioning members (10, 12). A row ejector then conveys the row on to a lowering table which is lowered in steps, each time by the effective thickness of a row, whilst, on the horizontal table (14), the subsequent can row is prepared in a position offset relative to the preceding row by the amount of a can radius. After a can pack with a predetermined contour, that is to say with a predetermined number of rows and with a predetermined number of cans per row, is stacked in this way in layers on the lowering table, a pack ejector plate (31) displaces the entire can pack into the tie-round frame (35) of a tie-round machine and into a shaping frame which is arranged immediately next to this and which is matched to the desired pack contour and holds the pack together during the tying-round operation. A holding-up plate, which is arranged parallel to the pack ejector plate (31) and which can be displaced by the pack itself, secures the vertical alignment of the cans in the pack. <IMAGE>
