Patent EP-0096853-A1 (EP)
Inventor: ATKINSON CYRIL JOHN
IPC: B65H3/02
Filed: 1983-06-09
Abstract: A mechanism for delivering sheets seriatim from a stack 29 comprises a primary feed member 42 which advances a separated top sheet 80 from the stack and a secondary feed 82, 84, which receives and locates the sheet from the primary feed and advances it to an image-bearing cylinder or drum 64 in timed relationship to the rotation thereof. The secondary feed rollers 82, 84 are required to be substantially stationary during operation of the primary feed so that the sheet 80 is fed into the nip between the secondary feed rollers and a small longitudinal buckle forms therein. This is achieved by means of gearing that when driven at a substantially constant speed drives the secondary feed roller 84 at an angular velocity which increases smoothly between zero during operation of the primary feed and a maximum value and then returns to zero. The gearing may be so arranged that there is a dwell at zero angular velocity. The secondary feed may feed the sheet into the nip of a rotary printing or duplicating machine or to the transfer station of an electrophotographic copier. <IMAGE>

Abstract: A process is disclosed for preparing a titanium catalyst component useful for homopolymerizing 1-alkenes and for copolymerizing 1-alkenes with each other and/or with ethylene, consisting essentially in grinding a titanium halide compound/electron-donor complex with a magnesium aluminum halide obtained by precipitation from an organic solvent. In the process the ground product is first washed with a washing liquid containing a solvent for the aluminum halide/electron-donor complex which forms during the grinding process and by preference at least one alcohol, the molar ratio between alcohol and titanium in the ground product ranging between 50:1 and 1:20, and then the washed product is exposed to a liquid titanium halide compound. With this procedure, it is possible to obtain a titanium component which imparts to the polymerization catalyst an excellent stereospecificity along with a very high activity, and with which it is possible to obtain polymers, e.g. polypropylene, with a very low halogen content, a very low titanium content, and an excellent powder morphology and bulk density.

Abstract: A cellular radio system in which the mobile radio stations in the zone of any base radio station assign themselves to the control channels allocated to that base station so as to evenly spread the volume of traffic over such control channels. The base station transmits on each control channel a channel group code signifying the range of group code numbers allocated to that particular control channel. Each mobile station stores its identifying group code number, scans the group code numbers of all control channels, and assigns itself to the control channel having a channel group code which includes its group code number. The spread of traffic over the various control channels can be changed by the base radio station simply by changing the channel group codes of the various control channels, without addressing specific commands to the mobile radio station.

Abstract: Dans le procédé pour extraire le lait du trayon d'un animal le lait est aspiré dans un dispositif d'évacuation du lait maintenu sous dépression. Dans ce but, le trayon fait saillie à l'intérieur d'une ventouse qui passe d'une phase d'aspiration d'une part à une phase de détente d'autre part par changements depression. Pour produire ces changements de pression on agit sur la ventouse successivement par surpression d'une part et par dépression d'autre part. En outre, dans la phase de détente, le trayon est séparé de la dépression du dispositif d'évacuation du lait d'une manière déterminée. On soumet la ventouse à une surpression dans la phase de détente, durant toute l'opération de traite ou seulement pendant des intervalles de temps déterminés, et le reste du temps à la pression atmosphérique. Dans le dispositif pour la mise en oeuvre de ce procédé l'espace (10) prévu entre la ventouse (18) d'une part et le gobelet (9) d'autre par est soumis à des changements de pression entre une surpression et une dépression. En outre, entre la pointe du trayon (34) et le dispositif d'évacuation du lait (1) est prévu un organe pour séparer le trayon de la dépression.
