IPC: B41J32/00
Filed: 1980-07-22
Abstract: The ink-ribbon cartridge (1) has a pin (7) which projects from the bottom of the lower housing part (1a) and is arranged between the ribbon supply reel (5) and the housing aperture (11) for the outlet of the ink ribbon (4). Located around the pin is a helical spring (8) whose one end bears against the inner surface of the lower part of the housing and whose other end points away from the pin and is bent parallel thereto. The bent end of the helical spring serves as a ribbon guide (9) in order to keep the ink ribbon constantly taut. By means of this tensioning ribbon guide (9), smearing of the document due to a loose ink ribbon can be prevented, in particular. <IMAGE>

Title: Dyestuff mixt. esp. for polyester textile - contg. brominated di:hydroxy di:amino anthraquinone and di:cyano nitro acetyl-amino di:ethylamino azo-benzene
Inventor: BRANDT HORST DR
IPC: C09B29/08
Filed: 1980-11-15
Abstract: Dyestuff mixt. consists of brominated 1,8-dihydroxy-4,5-diaminoanthraquinone (I) and 2,6-dicyano-4-nitro-2'-acetylamino-4'-(N,N'-diethyl)- amino- 1,1'-azobenzene (II) in a (I):(II) wt. ratio of 65-85:35-15 (70-80:30-20, esp. 75:25). The mixt. is specified for dyeing polyester fibres. (I) and (II) both have valuable properties for this purpose but (I) is costly to mfr., whilst (II) does not give esp. high fastness. The mixt. is favourable in cost and gives excellent liquor stability (unlike a mixt. contg. less (I), e.g. a 50:50 mixt.) and good fastness to light and sublimation. In an example, 1477 (wt.) pts. moist (I) filter cake (20% solids) and 104 pts. (II) filter cake (95% solids) were made into a paste with 130 pts. dispersant, 2 pts. anionic wetting agent and 140 pts. water, then mixed with 1615 pts. dispersant, 4.5 pts. antidusting agent and 45 pts. water and spray-dried. The dyestuff granulate obtd. contained 29.55% (I) and 9.85% (II). When used for dyeing a polyester textile, it gave very level blue dyeing with excellent fastness to light and sublimation.

Title: Office drawer with moulded handle recess - has reinforcement backing plate avoiding need for thick front wall
IPC: A47B95/02
Filed: 1980-12-06
Abstract: The front wall of the drawer is made of a foamed plastics material. It has in its front side a recess which may be used for a handle. The base of this recess (6) has a thin rigid plate (9) for reinforcement. The plate (9) is embedded in the material behind the base surface (10) of the recess so that the plate is covered by the foamed plastics. The base of the recess can now be kept quite thin since the additional plate provides the sufficient strengthening. No complicated deep-drawn parts are required allowing manufacture to be much simpler.

Abstract: This is an addn. to 2849003 which discloses the prepn. of new P-contg. cyanohydrins having formula R1(R2(O)nP:X)-CH2-CHR3-CR4(OR5)-CN (I) (where R1 is 1-12C alkyl opt. mono- or poly-substd. by halo, or 6-10C aryl, 7-10C aralkyl or 4-10C cycloalkyl; R2 is 1-6C alkyl opt. mono-or poly-substd. by halogen, 6-10C aryl, 7-10C aralkyl or 4-10C cycloalkyl; R3 and R4 are H, 1-4C alkyl, Ph or benzyl; R5 is H, 1-12C acyl, tri-1-4C-alkyl-silyl, 1-6C alkoxy-carbonyl or -P(:O)R6R7; R6 and R7 are 1-4C alkyl or 1-4C alkoxy; X is -O-or -S- and n is zero or 1). In this addn. (I; where R5 is H) are prepd. by radical former-catalysed reaction of phosphinates having formula R1(R2(O)n)P(:X)H (II), with cyanohydrins having formula CH2:CR3-CR4(OH)CN (IV). (I; where R5 is H) are used directly as raw materials for the synthesis of P-contg. aminoacids. (IV) remain stable under the reaction conditions. The use of (IV) in place of the cyanohydrin derivs. having formula CH2:CR3-CR4(OR'5)CN (III) (where R'5 is R5 with the exception of H) obviates the introduction of a protective gp.

Patent DE-3115563-A1 (DE)
Inventor: HOCKEMEYER FRIEDRICH
IPC: C08L83/04
Filed: 1981-04-16
Abstract: Coatings which have a predetermined degree of adhesive-repellency are prepared by applying to surfaces which are to be rendered adhesive-repellent an organopolysiloxane having Si-bonded hydrogen and an aliphatic multiple bond in the same molecule and a catalyst which promotes the addition of Si-bonded hydrogen to an aliphatic multiple bond, and thereafter crosslinking the organopolysiloxane by the addition of Si-bonded hydrogen to an aliphatic multiple bond. The organopolysiloxane having both an aliphatic multiple bond and Si-bonded hydrogen in the same molecule, has a viscosity of at least 300 mPa.s at 25 DEG  C. The adhesive-repellency of the coated substrate is at least partially dependent on the ratio of Si-bonded hydrogen to the aliphatic multiple bond, i.e., the higher the ratio of Si-bonded hydrogen to the aliphatic multiple bond, the lower the adhesive-repellency. Organic compounds containing at least one grouping of the formula   <IMAGE>   in an amount to retard or prevent the addition of Si-bonded hydrogen to an aliphatic multiple bond at room temperature, are to be excluded from the adhesive-repellent compositions of this invention.

Title: Device for applying transverse welded seams to thermoplastic tubular films, preferably tubular films with gussets folded inwards at the longitudinal edges, with two interacting welding jaws
Inventor: MUELLER MATTHIAS
IPC: B31B19/64
Filed: 1981-09-17
Abstract: In machines for producing, filling and sealing plastic bags and in machines for producing prefabricated plastic bags, difficulties occur in welding with tubular films gussets folded inwards at the longitudinal edges during the processing due to the double number of layers in the region of the gussets. To obtain the necessary quality of a weld seam, it is necessary to shape the weld jaws, which are pivotable about a common fulcrum, corresponding to the cross-section of the plastic tubular film. The permanently heated welding jaws according to the invention comprise a plurality of partial jaws, preferably four, the distance from the closed partial jaws to the different number of layers of plastic tubular film being adjustable. <IMAGE>

Title: Process for the production of a liquid-crystal display
Inventor: KOBALE MANFRED DR PHIL
IPC: B05D7/24
Filed: 1981-09-28
Abstract: In order to align the liquid-crystal layer quasi-homeotropically, the following alignment technique is proposed: the electrode plates are coated with a polymer formed in a glow discharge by means of a flowing monomer gas, with the gas stream and/or the axis of the discharge field being aligned at an angle to the plate perpendicular. The monomer gas preferably comprises a perfluorinated cyclic hydrocarbon with an admixed hydrocarbon (example: perfluorocyclobutane plus 10% of cyclobutane or butadiene). These glow polymers can be prepared uniformly and reproducibly to thicknesses of a few nanometres, are pore-free, temperature-stable and transparent, have good adhesion and are not attacked by conventional liquid-crystal substances. In addition, they have nonlinear electrical resistance. Area of application: (multiplexible) liquid-crystal displays having a homeotropic rest-state alignment; in particular displays having the bistability effect, and absorptive displays.
Patent DE-3142917-A1 (DE)
Title: Mechanism
Inventor: LIANG-CHIH WANG
IPC: F16H25/06
Filed: 1981-10-29
Abstract: The subject-matter of the invention is a mechanism in which an input disc is provided with a non-circular groove. By means of a pin guided in the groove, the rotary motion is converted into a reciprocating motion of a connecting rod to which is connected a slider likewise having a non-circular guiding groove. Guided in this guiding groove is a pin of the output disc, which, during the reciprocating motion of the slider, traverses a circular path and in this way brings about the rotation of the output disc. Different transmission ratios and directions of rotation can be achieved by different shapes of the grooves.

Title: Scrapers for scraper-flight conveyors in underground operations
Inventor: GARTE RUDOLF
IPC: B65G19/24
Filed: 1981-11-05
Abstract: Underground, coal is conveyed away in scraper-flight conveyors with round-link chains according to DIN 22252 to which the scrapers are screwed. The scraper has a rigid construction, i.e. it is forged and is therefore in one piece. It is not flexible. If the scraper is ever distorted, it has to be dismantled. The invention shows a scraper which consists of a spring assembly, the centre spring being pushed onto the round-link chain laterally, and the springs lying in front of and behind it being pushed onto the round-link chain from below and from above. The flexibility of the scraper spring assembly protects the round-link chain, and smoother running of the chain belt is ensured. <IMAGE>
