Title: Railway bridge with rails on concrete slab - has continuous slab able to accommodate relative displacements without ballast
Inventor: FASTENAU WERNER DIPL ING
IPC: E01D1/00
Filed: 1974-09-13
Abstract: The railway bridge supports track without ballast and the rails on the bridge area are fastened directly on a concrete slab. The bridge is built of horizontal beams and the length of such a bridge is not restricted and no difficulties are experienced due to the differential expansion between the welded track rails and the concrete bridge structure. The rails on the bridge are mounted on a concrete slab which rests on the bridge and covers the bridge length as a continuous unit. Hence this slab is ablto to accommodate longitudinal relative displacements. The bridge has dilation gaps on the superstructure covered by the track slab. The continuous slab can be fastened at each end of the bridge structure and it forms there a monolithic structure. Alternatively individual or all bridge pillars can be connected firmly with this continuous concrete slab.

Title: Adhesion promotion between metal film and insulating substrate - using intermediate layer and substrate with gps. interacting at surface
Inventor: JOSTAN JOSEF DR RER NAT
IPC: C04B41/52
Filed: 1974-11-09
Abstract: Adhesion promotion between metal films and electrically insulating substrates, esp. vitreous or ceramic substrates, using an adhesion-promoting intermediate layer comprises the selection of substances with active and reactive gps. for the substrate and intermediate layer, which interact at the interface. Acidic/alkaline, electrophilic/nucleophilic, electropositive/electronegatively charged or cation/anion active substrate/adhesion promoter combinations, or vice versa can be used. Alternatively, an almost neutral substate surface can be used with a strongly acid or alkaline adhesion promoter and/or made from strongly acid or alkaline by physical or chemical surface treatment. The process is more widely applicable to smooth substrates than that involving treatment with SiO2 before metallisation.

Title: Metallised plastics film for capacitors - with intermediate poly-crystalline insulating film, avoiding rupture voltage redn.(BE130576)
Inventor: EPPLE RICHARD DIPL PHYS DR
IPC: H01G4/14
Filed: 1974-11-14
Abstract: In the prodn. of metallised plastics film for electric condensers, a polycrystalline insulating layer is deposited from the vapour phase or produced before deposition of the metal coating from the vapour phase. The insulating cpd. can be an inorg. cpd., pref. Al2O3, SiO, Sio2 or Si3N4, or an organic cpd. based on polypropylene. The process avoids the formation of metal points due to diffusion into the boundary zones of the plastics film, which would lead to local very high field strengths, so that the rupture field strength would be reached at a much lower applied voltage than usual.

Title: Hyrostatic refuse collection vehicle drum - has motor driving drum gear annulus through four satellite pinions
Inventor: BERONIA MARIO
IPC: B65F3/22
Filed: 1975-09-18
Abstract: Refuse collecting vehicles consist usually of a rotating drum driven by a hydrostatic motor via chain or gears, and the drive comes from auxiliary cardan shaft of the vehicle engine. The disadvantages of this is the considerable noise generation of the chain drive and high wear of the cardan. The present arrangement eliminates this by using a hydrostatic driving motor with the output shaft extended into a pinion which meshes with four satellite wheels. These parts mesh with the internal toothing of a gear rim fixed to one end of the drum. By this arrangement the driving and seating of the drum is achieved at the same time. The other end of the drum is seated on roller supports on which the guide rim revolves.
