Title: High pressure gas discharge lamp - has parallel fluorescent lamp which lights as emergency light on interruption of supply
Inventor: MUELLER FRIEDR-WILH ING GRAD
IPC: H05B41/46
Filed: 1975-04-26
Abstract: A circuit for the operation of a high pressure gas discharge lamp with provision for switching in an emergency light on interruption of the supply, by the provision of a normal fluorescent lamp in parallel short-term interruption of supply which allows the high pressure lamp to cool so that it cannot immediately be restruck, the fluorescent lamp maintains illumination in the interim. The high pressure lamp (2) is in series with its ballast (1), and the fluorescent lamp circuit consisting of lamp (3a), starter (3b) and choke (3c) is directly paralleled with the high pressure lamp. In normal operations the voltage drop across the ballast unit (1) ensures that the voltage across the lamps is reduced to the burning voltage of the lamp (2) which does not suffice to strike the fluorescent lamp (3). On an interruption of current, the lamp (2) extinguishes, and immediately on return of voltage the lamp (3) lights until the high pressure lamp (2) cools sufficiently to ignite ballast unit (1) then causes the lamp (3) to extinguish. The circuit is fully automatic, without the need for any type of relay.

Title: Package sheet wrapping system - holds sheet taut inclined to travel direction welds together at trailing edge
Inventor: BAYER MANFRED
IPC: B65B9/02
Filed: 1975-05-09
Abstract: the system wraps a package in sheet material, the leading edges of the package running against a wall composed of two sheets joined together and held taut. As it continues to move the sheet is stretched and the package enclosed on some of its vertical sides. The sheets are then guided round the trailing edges of the package towards each other and joined by two successive vertical weld seams. The package, now enclosed on all vertical sides by taut sheet, is then parted off from the remainder of the latter between the two seams, so that a wall is left for the next package. the wall is tautened in a direction inclined to the direction of travel of the packages (1), so that only one leading edge runs against it.

Title: Cable box halves sealing system - uses opposed channels cut in flat mating faces to retain sealing compound
Inventor: HAEDER WOLFGANG
IPC: H02G15/013
Filed: 1975-11-04
Abstract: A cable box or muff is constructed in halve which are subsequently pressed together with a jointing compound on the mating faces, particularly the parallel faces in the form of laminations (2) at the ends of the box. If the pressure is locally too high all the sealant may be squeezed out leaving a leakage path, or there may be a very local defect giving the same result. The mating faces (4) are provided with grooves or channels (3) which are filled with the sealing compound. Thus when the mating faces (4) are brought together there will always be a filling present, similar to that provided by a gasket, and possible leakage points eliminated. The channels may be semicircular or rectangular in cross section.

Title: Gravity moulding of glass dishes - on ring die contg. piston which is lowered to suit depth required in the dish (SW 19.7.76)
Inventor: RUUSKANEN TOIVO JUHANI
IPC: C03B23/025
Filed: 1976-03-05
Abstract: Glass plates or dishes are made by pressing a gob against the top surface of a die, so the gob spreads out to form a flat blank. The core of the die is then moved w.r.t. the outer part(s) of the die so the central portion of the blank sinks to the required depth. The molten glass pref. sinks in the die due to gravity, and the pref. die consists of a ring surrounding a moving piston. The top surfaces of the ring and the piston are provided with contours used to achieve the profile required on the underside of the glass plate or dish; and the piston is lowered to suit the depth desired in the plate or dish. The ring and the piston may both move and travel at the same or different speeds in the same or different directions. Used for gravity moulding of glass objects, where one die set can be used to provide plates or dishes with various required depths.

Title: Three dimensional display mounted on corrugated base - provides two different pictures at different viewing angles by using strips stuck to faces of corrugations
IPC: B44F7/00
Filed: 1976-03-27
Abstract: The three dimensional display is produced by using a base (1) formed in corrugations with straight sides (3a, 3b) and a vertex angle of 90 deg. The base can be made of extruded plastics. A picture drawn on a sheet of paper (4) is cut along parallel lines (5) to form strips (6). The reverse side of the sheet (4) is coated with pressure sensitive adhesive. The strips are then stuck to all the left-hand sides of the corrugations of the base (1). A second picture which can be of a completely different subject is cut into similar strips. These strips are stuck to the right-hand side of the corrugations. When the display is completed, the picture which is visible depends on the angle of view.
