Patent EP-0430685-A3 (EP)
Title: Process for production of a highly pure silicic acid aqueous solution
IPC: C01B33/148
Filed: 1990-11-29
Abstract: A process is disclosed for removing non-alkali metals from an acidic silicate solution or suspension, the process comprising subjecting the solution or suspension to an electrochemical process in the presence of a strong acid and an oxidising agent such that non-alkali metals present form water-soluble salts, and ion-exchanging the solution. The acidic silicate solution or suspension may be generated by ion-exchanging an aqueous alkali silicate solution to remove alkali metals. The invention therefore enables a silicic acid aqueous solution having a low content of metal impurities, for example 1 ppm or less, to be prepared from an alkali metal silicate of low purity.
Patent EP-0464323-A3 (EP)
Title: Cooking hob
IPC: H05B3/74
Filed: 1991-04-11
Abstract: In glass ceramic cooking hobs, a decoration is usually printed on the surface receiving the kitchenware, e.g. to mark the cooking areas. It is disadvantageous that, when the kitchenware is displaced on the receiving surface, this decoration is rubbed off and after a long period of use becomes unrecognisable. 
<??>According to the innovation, this is avoided in that, for marking e.g. the cooking areas, the markings are formed by the plate material itself, which has in the region of these markings, a material structure which is different, e.g. matt, from the usual glass material.

Filed: 1991-09-11
Abstract: A communication system, particularly for communication satellites, with baseband switching and multi-beam antenna, with variable allocation of capacity to the individual transmitting beam lobes, characterised in that the baseband output signals of the switching system, which are allocated to the individual transmitting beam lobes, have a variable data rate and in that the individual baseband output signals are combined in accordance with their current data rate by means of modulators of the corresponding modulation data rate and are modulated onto in each case one carrier by means of the modulators. As a result, the transmission rate of the individual beam lobes can be changed flexibly and easily and can be rapidly adapted to traffic requirements changing over a short time. <IMAGE>

Title: Slot machine
IPC: A63F5/04
Filed: 1991-02-01
Abstract: In a slot machine, pay-out data about the past game that represent the relationship between the accumulated number of inserted coins and the accumulated number of paid coins, are stored and displayed. There is further provided a game simulation device which simulates the games that are intended to occur hereafter. The simulative games are repeated at a high speed with no coin insertion nor coin payment, during which the reels are not rotated. Hypothetical coin pay-out data are formed based on the accumulated number of coins assumed to be paid out for the simulative games on the assumption that a predetermined number of coins were inserted for each simulative game. Also the hypothetical coin pay-out data about the following games are displayed as requested. <IMAGE>

means is first activated so as to break the earth leakage 
current which is danger to the human body. The second 
earth leakage-current detecting means can make a 
protection coordination with respect to the earth leakage 
current.

Abstract: In a capillary evaporator for use in a capillary pumped loop, in which capillary action in
a porous wick 7 causes cold liquid to be drawn across the wick and vaporised by a heat
input structure 6 and in particular fin 8 of that structure so that the vapour passes around
a loop and rejects heat at a condenser in order to cool equipment in the vicinity of the
evaporator, the vapour generated in the wick 7 from the liquid/vapour interface
(meniscus) 11 is subject to a lower pressure drop than hitherto by virtue of spacer 14
of greater permeability and thermal conductivity than the wick 7 without the necessity
for the meniscus 11 to recede from the fin 8 which would cause an undesirable
temperature drop of the meniscus, thereby improving the capacity of the evaporator to
pump liquid/vapour around the loop and thus transport heat.
