Title: Road traffic information transmitting system - superimposes traffic information on normal programmes on car radios when radio has been preset by low power roadside area code transmitter
IPC: G08G1/09
Filed: 1980-10-24
Abstract: Transmitters sending traffic information to be superimposed on normal regional F.M. broadcast programmes received by car radios are in use in several European countries. When the traffic information is transmitted, it triggers a switching circuit in the receiver which switches the receiver amplifier input from the entertainment programme to the traffic signal. The system goes one step further, in that the region is divided into zones (zi,zj), and small, e.g. 100 milliWatt, automatic transmitters (i) placed at short intervals along the road send a binary code which is used by a multiplexer in the receiver to select only those messages relating to the zone through which the vehicle is passing.

Patent NL-8401204-A (NL)
Title: Locking system preventing roller shutter door from being opened - allows horizontal linked slats to hook behind blocking stops in profiled guides at sides
IPC: E06B9/80
Filed: 1984-04-13
Abstract: The blocking system allows the shutter's slats to piVot about their linkage axes. The shutter is guided at its sides by profiling resembling a periodic wave with blocking steps. The shutter falls under its own weight, sliding smoothly over the wave. When its bottom edge reaches the ground, the slats pivot into a zig-zag with the pivot axes beneath the blocking steps. Lifting the bottom slat pushes the pivot axes against the steps and will not raise the shutter. Raising the top slat pulls the axes away from the steps and the shutter can be raised.

Title: Method of blind-fastening plate-shaped parts to walls and the like, and plate-shaped parts and bolts with provisions therefor
Inventor: BERG PIETER VAN DEN
IPC: E04F13/08
Filed: 1994-04-29
Abstract: Method of blind-fastening plate-shaped parts to walls etc, and plate-shaped parts and fastening bolts with provisions therefor. A hole is milled into the rear of the part, the hole having a diameter somewhat greater than the largest linear dimension of the head of the bolt to be used and being perpendicular to the axis of the bolt, as far as about 2 mm from the front wall. From that hole a slot is milled sideways which slot, as seen from the bottom, has converging walls so that the width of the opening in the rear wall is somewhat greater than the diameter of the bolt. The head of the bolt is positioned in the hole, and the bolt is then pushed into the slot. Since the walls of the slot run obliquely and the outer surface of the head of the bolt is conical at an angle which corresponds to the slope of the walls it is possible for relatively thin parts - thickness about 6 mm - to be fastened thus, while the pull-out value (pull-out force) is still sufficiently large - larger than 1600 N.
