Patent EP-0006553-A1 (EP)
Inventor: ERNST LARRY MASON
IPC: G03G15/20
Filed: 1979-06-15
Abstract: Method and apparatus for operating and regulating a heat soucre (103) in a reproduction machine, particularly for a fuser in a copier. The machine is operable in at least 3 modes, a warm-up, a stand-by, and a copy mode. The amount of energy supplied to the heat source (103) depends on the present mode of the machine and the actual temperature T of the fuser: 
     The supplied power is at level P1 during the warm-up mode until T T1 (T1 is a given temperature). Then, power is reduced to P2. In stand-by mode, power is increased to P2 + \ P1, if T < T2 (T2 is a given operating temperature), and decreased to P2 - \ P1, if T2. In the copy mode, power is increased to P2 + \ P2 if T T2 and increased to P2 + Δ P3 it T Δ T2.

IPC: F02C3/073
Filed: 1980-04-09
Abstract: A turbinedriven turbocompresser is a multi-stage machine composed of a number of uncoupled concentrical work-wheels which within a common housing (1) between two stationary guiding-blade wheels (2 and 3) are alternately counterrotating and which are equipped with blade rings that in the row of wheels form corresponding flow passages for respectively both expansion (8-9) and compression (10-11). Flow directions for compression and expansion are opposite, stationary guiding-blade wheels as well as rotating work-wheels are constructed in the form of disks. The rotating wheels (4) and (6) are identical. Because of the low angular speeds of the rotating wheeldisks grease-filled spiral-groove bearings as well as gaslubricated bearings can be applied.

IPC: A47J31/42

Abstract: The invention introduces an apparatus and a method whereby most of the enticing fragrances and aromas of foodstuffs, like coffee for instance, which otherwise, by the methods employed heretofore escaped during roasting and/or grinding, can be used and mixed or absorbed in the drink. 
     This object is achieved by roasting, grinding and infusing the coffee in the same (heatable) container (113) or basket, i.e. without transferring the roasted coffee beans to another work-stationforgrinding, and by the fact the hot water and/or steam, while dropping down from the top of the vessel (120) surrounding the basket, gets in touch with the fragrances and aromas developed during roasting and grinding, mixes with them and absorbs some or most of them. This feat is achieved through the apparatus which features a heatable basket (113) for hard or soft foodstuffs and a rotating blade (112) to ensure a uniform roast. When the beans are roasted, the heating of the basket is switched off and the blade is rotated at higher speed, whereby the roasted stuff is ground. At the same time water is heated and the hot water and/or steam is lead to the top of the (practically) closed unit from where, while dropping, the water and/or steam mixes with and absorbs the aromas and fragrances, reaching the basket and its contents, leaches the grind and, through perforations on the basket, drips to the bottom of the vessel.

Abstract: A driving device for endless form webs (23) with marginal perforations is to operate in such a way that driving is possible in forward and reverse direction without offset of the line, but that at the same time the web is stretched taut at the printing point to reduce noise. For this purpose, drive elements, preferably cog wheels (15), at which a reversal of direction takes place, are used before the printing point, said drive elements acting with positive engagement and being equipped with barbs. After the printing point, two transport rollers (17, 27) as drive elements act with frictional engagement on the form web (23) in such a way that the roller (27) acting on the upper web runs faster than the roller (17) acting on the lower web, both rollers (17, 27) having a greater circumferential speed than the cog wheels (15). <IMAGE>
