Title: Regeneration of hydrocarbon conversion catalysts - using dense-phase riser-mixer zone preceding relatively dense phase fluidised bed coke combustor
Inventor: THOMPSON GREGORY JOHN
IPC: B01J23/90
Filed: 1980-02-22
Abstract: In the regeneration of hydrocarbon conversion catalysts deactivated by coke deposition, the regeneration being carried out by coke burn-off facilitated by an O2-contg. regeneration gas in a relatively dense phase fluidised bed coke, combustor, the improvement consists of providing a riser/mixer zone (I) in which incoming deactivated catalyst is mixed with a portion of regeneration gas and a portion of regenerated catalyst split off the stream recycled from the regenerator to the conversion zone. (I) is operated in the dense phase and upstream of the relatively dense phase conventional coke combustor. The first portion of regeneration gas is passed into the dense phase and the last into the relatively dense phase; the mixing of deactivated catalyst, regenerated catalyst and regenerated gas being effected above the point of entry of regeneration gas into the dense phase. Used esp. with fluid catalytic cracking processes. Circulation of regenerated and spent catalyst through (I) improves the dispersion of spent catalyst throughout the regeneration zone and minimises the problems of poor catalyst distribution.

IPC: F02G5/00
Filed: 1980-06-27
Abstract: The system has a heat exchanger, an evaporator, a condenser, a compressor and a heat carrier circuit. There is a cooling medium circuit and a heating medium circuit. Exhaust gas from the I.C. engine is transferred to the heating medium circuit in a heat exchanger and the feed temp of the circuit to consumers is regulated. The heat exchanger is formed as a heat store. At low heat demand from the consumers, the store is heated and none or a small amount of heat only is transferred to the circuit. When the store temp has reached a certain level, the I.C. engine is switched-off. The feed temp of the circuit is adjusted by a controlled heat input from the store. The engine is switched-on again, when the store temp reaches a certain low level.

Title: Method for producing decorative glass objects
IPC: C03B19/02
Filed: 1980-10-24
Abstract: PCT No. PCT/FI80/00001 Sec. 371 Date May 13, 1981 Sec. 102(e) Date May 13, 1981 PCT Filed Oct. 24, 1980 PCT Pub. No. WO81/01142 PCT Pub. Date Apr. 30, 1981.A method for producing decorative glass objects in which the decoration is created by blisters formed by air bubbles within solid glass and/or by a pattern on the outer surface of the glass. When producing glass objects provided with air bubbles by means of known methods the bubbles remain on the surface of the objects which then easily break. In addition, the bubbles are formed at random, which may make them appear as dim impurities. When, in accordance with the invention, molten glass is poured from above in the shape of a band into a hot mould, the molten glass is spread into the mould in layers between which microscopic air bubbles remain. As the glass surface cools, the air enclosed within the bubbles expands in the molten glass which, while cooling, leaves the bubbles as clear pearls inside the glass. As the molten glass is spread in layers towards the wall of the mould, a pattern is formed as the glass surface cools.

Title: Steering apparatus for toy vehicles
Inventor: BITTNER HANS
IPC: A63H31/08
Filed: 1981-02-28
Abstract: The steering apparatus for toy vehicles permits simple handling, uncomplicated construction and good switching properties, by means of which a change of direction to the desired direction of travel can be carried out with a high degree of operational reliability and little wear, without further manipulation. The production of these steering apparatuses for toy vehicles is very simple in comparison with conventional steering apparatuses: the function switches off a tooth-against-tooth position, the engaging and entraining elements, entraining pin and entraining peg, completely switch off such a position, since the engagement surface area has been greatly reduced. A very important point here is the loosely mounted pinions and the movement of the disc with the entraining pin. Such an arrangement has a very beneficial effect on switching in toy vehicles.

Title: Time division multiplex switching network
Inventor: BINZ REINER DIPL ING
IPC: H04Q11/06
Filed: 1981-03-13
Abstract: The time division multiplex switching network is built up from units which effect switching purely on a time basis through cyclic writing into an information memory and random read-out from the same. According to the invention, an economical switching network design is achieved in that the components are built up from modules (BS1, BS2; BSR0 to BSR15) whose similarly disposed inputs are interconnected, via which more PCM words are entered per pulse frame and component than are randomly read out. In the case of units which are used for time and space division switching and which are located on the input and output sides of the switching network, all incoming PCM words can be stored. The number is lower in units in intermediate switching stages due to the connection of PCM lines with a higher transmission frequency, wherefore they can be used essentially for space switching only. The result of this is greater connection numbers per unit, lower component cost in intermediate switching stages, and lower wiring cost. <IMAGE>
