Patent DE-3467737-D1 (DE)
Title: Cartridge for a ribbon for typewriters
Inventor: GUBAU JOSE
IPC: B41J32/00
Filed: 1984-04-06
Granted: 1988-01-07
Abstract: The cartridge comprises a container (7) of substantially parallelepipedal form with its corners radiused and rounded off. The container is provided with a back (8) having a slot (27) adapted to guide a slide (26) on the ends of which are rotatably mounted a feed spool (22) and a take-up spool (32) on which the ribbon (21) is wound. A spring (36) engaged with a stud (41) on the slide keeps the slide (26) towards the right-hand side of the container with the take-up spool (32) engaged with the pin teeth of a feed roller (42). As the turns of ribbon wound on the take-up spool increase, the slide shifts with the two spools towards the left-hand side of the container in opposition to the action of the spring. The cartridge is mounted removably on a support of the machine which is inclined with respect to the horizontal plane of the machine passing through the printing point in a manner such as to permit visibility of the printed characters.

Title: Cationic polymerisation of 1-olefins
Inventor: SAMSON JOHN NORMAN REID BP CHE
IPC: C08F/
Filed: 1984-11-01
Granted: 1988-02-25
Abstract: This invention relates to a process for producing polyisobutene which has at least 70% of its unsaturation in the terminal position. The process uses a complex of boron trifluoride and alcohol as catalyst and a contact time of at least 8 minutes. The feature of the process is its ability to use longer contact times than used hitherto thereby facilitating its commercial operation and improving the control of such an operation. The high terminal unsaturation improves the reactivity of the polymer.

Granted: 1989-03-09
Abstract: A method for hydrolyzing coffee extraction residue materials to produce manno-saccharides having a degree of polymerization from 1 to 10 and subsequently neutralizing and reducing said mixture of manno-saccharides to their corresponding alcohols. The coffee material, preferably spent coffee gounds from a commercial percolation system, is hydrolyzed in a Plug Flow tubular reactor in the presence of an acid catalyst, such as sulfuric acid. Depending on the time, temperature, pressure and catalyst concentration selected, manno-saccharide or mannose is produced. The manno-saccharides or mannose produced are separated from coffee residue material in the form of a syrup and neutralized with calcium hydroxide. The neutralized mixture of manno-saccharides or mannose is reduced to their corresponding alcohols or mannitol.

Abstract: The keycard consists of a conducting carrier, with a surface code arrangement of conducting and insulating layers. The insulating layer has a matrix of spaces which form the coding elements, lying on conducting strips with only a part in direct contact with the carrier. The spaces are arranged according to a certain pattern so that they cover the strip partly or fully. Because of an additional formation in the strips, other codes can be inserted into the system, depending on different resistances. All spaces for the coding elements are covered with a conducting layer which is not transparent. The code reading equipment includes contacts which translate the code impressed into a voltage and this voltage (or voltages) is passed to porential contacts for transmission to the electronic equipment, with comparators. Blank coding contacts, only connected among themselves and not with the potential contacts may be provided. It is also possible to incorporate threshold values into the comparators in order to eliminate spurious coding efforts.

Abstract: An apparatus and process for spraying liquids wherein means are provided for subjecting liquid emerging from the sprayhead (1) to an electrical field sufficiently high for the liquid to be drawn from the sprayhead in the form of one or more filaments. The filament or filaments become unstable and subsequently break up into droplets. A stream of gas is caused to flow through the region of the high electrical field, the gas flowing in a direction parallel or substantially parallel with the direction in which the liquid emerges from the sprayhead. Droplets are thus removed from the region and a build-up in space charge is reduced.

Abstract: In a process and an apparatus for the biological purification of water with the aid of a closed trickling filter which is operated with pure oxygen and/or air, and with a downstream upwards filter with floating matter and intermittent flushing, the saturation of the gas blanket which mainly contains oxygen in the pressure trickling filter is controlled by choosing the operating pressure so that the oxygen supply on the one hand corresponds to the biochemical oxygen demand of the water, and the on the other hand a residual oxygen content dissolved in the water makes continuation of a biological final purification in the upwards filter possible, and thus replaces conventional final clarification. <IMAGE>

Abstract: A low loss fiber optic coupler is fabricated by forming a coupler preform (21) having a plurality of spaced glass cores (26, 27; 26', 27') extending longitudinally through a matrix of glass (21) having a refractive index lower than that of the cores. The coupler preform is heated and stretched by first pulling means (40, 76) to form a glass rod which is drawn by second pulling means (46, 77) past an intermittant source of localized heat (451. When the localized heat source is turned on, the second pulling means (46, 77) draws the rod downwardly at a rate faster than the first pulling means (40, 76). Since the rod is softened by the localized heat source, a necked-down coupling region (51) is formed. The rod is severed to form a plurality of coupler units (81, 87). When an end of a unit is immersed in acid, the matrix glass dissolves, thereby leaving the unit cores and surrounding etch-resistant cladding glass protruding from the newly formed endface of the unit.

Date Aug. 13, 1987.Ethanol is produced by fermentation of beet or cane sugar molasses in a fermentor. The ethanol formed in the fermentor is recovered by operating a primary distillation step (PD) in circulation circuit with the fermentor (FI). From the fermentor (FI) a mash stream (5) is continuously withdrawn, and after separation and recirculation of the yeast contained in the mash (5), the yeast-free mash is supplied to the primary distillation step (PD). A part (14) of the bottom stream (13) from the primary distillation step (PD) is recirculated to the fermentor. By controlling the water input to the process circuit so that the concentration of non-fermentable substance in the fermentor (FI) during a first period of time is increased from a start value in the range 5-15% by weight DS to a value in the range 20-30% by weight DS and maintaining the last high concentration during a second period of time so that the average content of non-fermentable substance in the fermentor during said two periods of time exceeds 20% by weight DS, a on average very concentrated stillage can continuously be discharged from the process.

Abstract: A guide chain for carrying lines that supply all types of expendable material from a fixed connection to a movable consuming device. In order to provide the guide chain with a periphery that is as completely closed as possible and has as smooth a surface as possible, and in order to be able to assemble the individual parts in a straightforward manner, two basic variants are proposed. In one variant, recesses are provided in the side pieces and are respectively concentric to a pivot axis between that side piece and an adjacent side piece, with externally circular cylindrical cover elements being inserted in the recesses to cover horizontal gaps between adjacent chain links. Caps are provided to connect adjacent side pieces, with each cap having a concentric rim that extends into the recesses and grooves that interconnect the latter. Each cap also has projecting members that are disposed between stops of adjacent chain links. These projecting members limit the maximum pivot angle of adjacent chain links.
