Title: Plastics panels edge joined esp. on site - by bonding edges into same or adjacent channels of trough sections
Inventor: KLEINDIENST BERNHARD
IPC: B29C65/54
Filed: 1979-09-29
Abstract: A method of joining and sealing together the parallel edges of plastics plates or panels consists of placing these edges alongside each other in a channel-shaped or V-shaped trough, then filling the trough with a casting material. Pref., a casting material which forms a firm bond with the plastics panels and with the trough is used. More specifically, a polyurethane or polyester casting material is used, the panels and trough being of rigid PVC. Used in particular for building and civil engineering, to form joints on site between plastics panels without the use of sealing equipment etc. The method is simple and permits comparatively large tolerances to be accommodated.

Title: Foil-packing objects using successive conveyors - uses time-delayed stops to narrow gap between objects and transversely seal and cut foil
Inventor: BECK HANS
IPC: B65B9/02
Filed: 1979-10-01
Abstract: The mechanism for foil-packing objects (6) comprises successive conveyors (3,2,11), with a station (7) to longitudinally seal (10) the foil (8,9) supplied from above and below on one conveyor (2). A station (11) between the conveyors (2 and 1) transversely seals and cuts the foil between successive objects (6c,6b). The conveyors (2,1) initially move at the same speed until a sensor (15), e.g. a photo-cell, upstream of the station (11) causes a delayed temporary stop of the conveyor (1) when the trailing edge of an object (6b) passes. The sensor causes a delayed temporary stop of the conveyor (2) when the leading edge of the next object (6c) passes.

Title: Transductor with variable air gap width - increases response slope by varying gap width linearly with air gap to reduce cushion distortion in TV
Inventor: POLLAK ALFRED
IPC: H04N3/237
Filed: 1980-02-16
Abstract: The transductor has a control coil, a working coil and a core with an air-gap. The width (d) of the air-gap (11) varies over the cross-section of the core (8,9). The width of the air-gap on one side of the core limb is zero and increases towards the other side. The width increases linearly. The boundary surface of the air-gap is flat or curved. The width of the air-gap may increase towards the outer edge of the transductor's core. The transductor is for use in eg a television receiver for controlling the amplitude of the line deflection current (E-W cushion distortion correction). The air-gap improves the transductor's overdrive range, slope and linearity.

Title: Window pane electric heating system - has automatic switch, disconnecting panes from electric network in case of pane breakage
Inventor: JOEST ULRICH
IPC: H05B3/84
Filed: 1980-07-28
Abstract: The heating system uses electric conductors on the pane(s) periphery. The heating current is interrupted during breakage of the glass pane by an automatic switching device (23) which separates the glass panes (S1-S6) from the mains completely in such instance. The switch pref. contains a bistable starting relay, in front of which is series-connected a comparator and a transistor. The bistable relay can be reset only by a reset pushbutton for exclusively manual operation. The automatic switch may be allocated to several window panes. If the window panes are also used for heat insulation, they may be coated with a conductive heating layer. The switching device discerns between mains failures and a defective glass pane. The system can be used with advantage in refrigeration and deep freezing installations for windows affording inspection despite greater temperature differences.
