Title: Paint roller for ceiling corner edges - has frusto=conical roller with contact ring, concentric with central spindle
IPC: B05C17/02
Filed: 1983-03-31
Abstract: The roll (1) is constructed of support drum (2) to which a covering (3) is applied, and which is rotatable on a central spindle (4) with a hand grip (5). The frusto-conical roll enables difficult ceiling corner application without smudging adjacent surfaces which should be kept free from paint. The roll has a contact ring concentric with the central spindle. The ring is height adjustable, enabling painting of stepped adjacent surfaces. The support (2) has a conical outer wall (7), which at the end of the smallest dia., contacts an outer conical part (8), approx. at half the height of the conical outer wall. A disc (9) carries sleeves (10) enabling a spring-loaded pin (11) to contact an end baffle (12).

Title: Desulphurization agent for a metal melt, consisting of calcium carbide and an organic binder
IPC: C22B1/244
Filed: 1992-10-08
Abstract: The invention relates to a product for desulphurizing a liquid melt, in the form of granules of calcium carbide powder coated or agglomerated (caked together) with the aid of a binder which consists of either an organic product having a melting temperature of 70-100 degree C, or of a polymer resin whose polymerization temperature is 40- 70 degree C. In particular, this product consists of calcium carbide granules which are coated with a first layer of binder which is solid at ambient temperature and, if required, with a second more or less continuous outer layer of finer calcium carbide granules which in turn are coated. The carbide powder can be a finely ground powder whose grain diameter is between a few μm and 250 μm, while the binder can be a pitch, stearic acid or a saturated glycerol/fatty acid ester.
Patent NL-9400944-A (NL)
Title: Cat litter box
Inventor: STEEN HENRICUS JOHANNES WILHEL
IPC: A01K1/01
Filed: 1994-06-10
Abstract: Cat litter box comprising a dish-like bottom tray for holding a cat litter filling, on which bottom tray a top cap can be removably placed, which cap substantially covers the bottom tray, and in which cap there is an opening creating a passage for the animal using the cat litter box. An insert tray is placed in this bottom tray, in such a manner that there is a closed space between the bottom of the insert tray and the bottom of the bottom tray. The insert tray has a funnel-shaped base with an opening at the lowest point, in which opening a screen- like member is arranged. The insert tray is filled with grains of a hydrophobic material, such as for example polypropylene and/or polyethylene. Consequently, the urine flows down through the grains and, via the opening in the base of the insert tray, enters the closed space between the insert tray and the bottom tray. The opening in the bottom of the insert tray is in this case advantageously provided with a stench-trap, thus preventing urine odour which collects in the closed space from spreading. The hard excrement remains behind on the granules and can easily be removed using a scoop.
