Title: Optically magnifying display arrangement - uses laser scanner and optical fibres linking image surface and panel points
Inventor: SANDER HEINRICH DIPL ING
IPC: G09F9/305
Filed: 1980-03-19
Abstract: A laser (L) scans the image to be presented line-by-line An optical enlarging system projects the image appearing on the image surface onto the display panel. The optical system is formed from a set of optical fibres (L1-L3) that couples corresponding points of the image surface (BF) with the display panel (AT). The distance of the surface (BF) from the panel (AT) is essentially determined merely by the vol. required by the optical fibres to give the desired enlargement. The panel (AT) has a layer (NS) presenting a residual image when optically excited. This layer (W5) is pref. made from a substance converting UV radiation into visible light. The laser (L) is controlled by an illumination level control (HST) and a deflecting stage (ABL) receiving data from an image memory (BSP).

Title: Mechanical atomiser burner with discontinuous fuel injection - has valve closure periodically opened by fuel pressure at preselected rate
Inventor: SAIER RUDOLF DIPL PHYS
IPC: F23D11/40
Filed: 1980-03-28
Abstract: The mechanical atomizer burner is for liq. or gas fired furnaces, esp. boilers or ovens. The fuel is fed discontinuously at a high pulse rate. The fuel is not fed directly into the burning area but rather in a pre-mixing chamber where it is subjected to turbulence with air to form a combustible mixture. It is then blown into the burning zone. A blast boxis positioned before the injection jet. The injection jet is closed by a mechanical, spring-loaded valve. The pressure of the spring is adjusted so that the valce closure is periodically opened by fuel pressure at a desired pulse rate. Alternatively, the injection jet is closed by an electro-mechanical, magnetically-loaded valve closure also periodically opened by the pressure of the fuel.

Title: Tunnel kiln for travelling goods has gas burners - in refractory chambers at intervals along kiln
Inventor: PATESOTTI CORRADO
IPC: F27B9/38
Filed: 1980-05-09
Abstract: A gas-heated tunnel kiln with goods transported on mobile pallets has individual burners at intervals along the kiln, above the goods with each burner housed in an enclosed refractory combustion chamber. At the base of the chamber are two apertures directed obliquely downwards from which the hot combustion gases emerge to heat the goods travelling on racks through the kiln. The refractory chambers are mounted in recesses in the tunnel masonry, and gaps may be sealed with insulating material such as ceramic fibres. Used for firing or enamelling ceramic tiles stacked on pallets. Since heated gases are deflected as eddies from the tunnel walls and enter between the tiles, more uniform heat distribution is provided than with known kilns which had burners in the side walls or acting directly on the tile tops.

Title: Copy lifter for photocopier - uses thin band or wire on pivot mounting to lift leading edge of copy
Inventor: FLORA ANTON ING GRAD
IPC: G03G15/00
Filed: 1980-07-26
Abstract: One end of the wire is secured to a lever pivoted at one end of the process cylinder and operated by an offset pin on its other end. The lever pulls the tensioned wire against the edge of the drum, against the direction of rotation to lift the corner of the copy sheet. The lever is released soon after and the sheet peels off the roller without daming the toner image. The lifter is simple and operates mechanically with the rotation of the process drum. It only touches the edge of the drum and one corner of the copy sheet. A return spring on the operating lever and a spring on the wire align the lifter without further adjustment required. The wire is non magnetic and anti-static so that it does not pick up stray toner.

Title: Method for the production of an object having a plurality of longitudinally distributed projections by forging
Inventor: HATSUNO HIROSHI
IPC: B21J1/06
Filed: 1981-02-21
Abstract: An object, e.g. a camshaft (1), is produced in one piece with a plurality of longitudinally distributed projections (2 to 6) by forging. On a blank (1') for the production of this object, the sections on which the projections (2 to 6), e.g. annular cams, are to be formed, are heated to temperatures (e.g. t2, t3', t4, t5, t6') higher than those of the other sections. The temperatures to which the individual sections serving for the formation of projections are heated are each approximately proportional to the radial dimensions of the corresponding sections (2 to 6) of the blank which are pressed out of the circumferential surface of the blank and form the projections. An apparatus by means of which corresponding differential heating of individual sections, in particular multi-dimensionally differentiated heating, can be achieved is furthermore specified. <IMAGE>

IPC: B25D5/00
Filed: 1981-02-26
Abstract: A centre punch (1) for marking hole centre points on workpieces (15) is to be created which is of compact design and can be manipulated easily and reliably. It consists of a steel pin (single-point tool 4) which is provided with a point (2) and is guided on the one side in a centring taper (6) which can be inserted into the open end of the through-hole (17, 19) in one workpiece (16). On the other side, it passes through an aligning bush (7) which is coaxial to the centring taper (6) and arranged at a distance from the latter. It is essential here that the centring taper (6) and the aligning bush (7) are firmly connected to one another, i.e. in one piece, and are displaceably guided together free of play in a casing sleeve (8). The bottom end of the casing sleeve (8) has a stop/locating surface (13) orientated normal to the common longitudinal axis of steel pin or single-point tool (4), centring taper (6) and aligning bush (7). Via the stop/locating surface (13), the centring taper (6) and the aligning bush (7), the steel pin or single-point tool (4) is aligned exactly with the longitudinal axis of the existing through-hole (17) in the workpiece (16) and thus the exactly matching marking of the hole centre points on the other workpiece (15) is ensured. <IMAGE>

Title: Contact copying process and apparatus to carry it out
Inventor: GORDON ROBERT ARTHUR
IPC: G03B27/08
Filed: 1982-02-26
Abstract: A contact copying process is described, in which a strip-shaped original film bearing negative or positive images is brought into direct contact with light-sensitive duplicating film and is passed in this state at as uniform as possible a speed past a copying window of an exposure station in which the light-sensitive duplicating film is exposed through the original film. To prevent the transfer to the duplicating material of optical faults such as, for example, scratches and scores, vapour, preferably of an inert liquid, is directed onto the mutually facing surfaces of the two films, and condenses in a microscopically thin layer on the surface of the two films in the immediate vicinity of the gap which opens on the supply side. The use of a liquid which is as inert as possible prevents toxic vapours arising. An apparatus to carry out the process has a vapour producing device and a vapour distributor device situated in the immediate vicinity of the gap which opens on the supply side.

Title: Jaw iron of a releasing ski binding
Inventor: NITSCHKO THEODOR
IPC: A63C9/00
Filed: 1982-06-30
Abstract: The invention relates to a jaw iron of a releasing ski binding which has two sole-holding arms which are pivotable in a basic body and are supported on a two-part slide which is displaceable in the longitudinal direction of the ski counter to spring force. Provided between the slide parts is a coupling device which is releasable in dependence on the slide stroke. Provided on the slide part which is movable relative to the sole holding arms after release of the coupling device is a component which is coaxial with the spring and bears an abutment for the spring. In the case of jaw irons of this type, it is disadvantageous that they can be caused to release by a jolting load which would actually still be harmless to the skier's foot. There is therefore a requirement for a jaw iron which does not release in the case of harmless jolting loads. This is achieved by the fact that the component forms the one movable slide part and is detachably connected via the coupling device directly to the other slide part, and that a hydraulic damping device is assigned to the component. In addition to constructional simplification of the jaw iron, the latter is thus capable of differentiating jolting and harmless loads from other loads leading to release and of avoiding undesirable release.
