Patent NL-8003567-A (NL)
IPC: G06F19/00
Filed: 1980-06-20
Abstract: An appliance including a digital programming device for forming a sequence of control signals. When the device is switched on by way of the power supply plug, an unpredictable switch-on phenomenon occurs and the program memory is liable to be addressed in a variety of locations. Therefore, during a preparation routine the start conditions are realized. Furthermore, a multi-bit code is generated and stored in a volatile section of the memory. The operative routine comprises a sub-routine which tests this code. If the code is not correct, the preparation routine has not been followed when the appliance was switched-on. The operative routine is then interrupted and first the preparation routine is executed. All further locations in the non-volatile memory section preferably refer to the preparation routine.
Patent NL-8100789-A (NL)
Title: Liquid-covering layer application and removal equipment - delivers liquid into vessel containing lighter covering components
IPC: E04H4/08
Filed: 1981-02-18
Abstract: The equipment applies and removes a covering layer on the surface of liquid in a reservoir, e.g. swimming pool. The layer comprises a number of components of material whose specific gravity is less than that of the liquid (1) to be covered, and which are spread over its surface from a storage vessel (2) into which part of the liquid is delivered. This forces them through an opening connecting the vessel and reservoir and onto the surface of the liquid in the latter. They are removed from the reservoir surface by lowering the liquid level in the vessel, whereupon liquid flows into the latter from the reservoir, taking them with it. After separation from them, the liquid is returned to the reservoir.

Title: Roll-up dressage ring
IPC: A63C19/06
Filed: 1993-09-23
Abstract: The invention relates to a dressage ring as used in equestrianism. These dressage rings are used internationally in competitions, have fixed dimensions, namely 20 m x 40 m and 20 m x 60 m, and form rectangular riding tracks with a perimeter of 120 and 160 metres, respectively, which are equipped with prescribed markings by means of letters according to the F.E.I. (Féderation Equestre Internationale) regulations. Hitherto, small wooden gates have been used for this purpose, placed freely next to one another on the ground, or alternatively planks which are placed on the ground with the aid of supports. These wooden fences have the following drawbacks: they require large amounts of storage space, taking them down requires considerable work, they need maintenance (painting, repairs), they are dangerous to horses' legs (splinters) and are expensive. It takes a long time to precisely measure out the rings, and the letter boards have to be arranged separately. The object of the invention is to solve the above problems and to make it easier to set up a dressage ring. To this end, it proposes a roll-up dressage ring, in which the complete ring is stored on a compact reeling trolley onto which it is possible to wind up a strip with a length of 120 or 160 metres, with letter boards attached at the distances specified by the F.E.I. This strip is safe for the horses' legs and does not require any maintenance, and is designed in such a manner that the ring is easy to stretch out and square up. The characteristic feature of this roll-up dressage ring is that the entire dressage ring and its accessories are stored on an easily portable reeling trolley.
