Patent DE-3819813-A1 (DE)
Inventor: EHMIG GERHARD
IPC: B25C1/18
Filed: 1988-06-10
Abstract: The powder-actuated fastening tool possesses a piston guide (5) and a driving piston (8) displaceable therein. By means of braking balls (17) displaceably mounted in recesses (16) in the piston guide (5), the driving piston (8) is braked in the driving-in direction in that a spring (18) forces the braking balls (17) against the shaft (11) of the driving piston (8). On displacement of the driving piston (8) in the opposite direction to the driving-in direction, the braking balls (17) move in the recesses (16) out of the tension range of the spring (18), as a result of which the driving piston (8) is not subjected to any braking action.

Title: Workpiece carrier for working the edges of hollow knife hafts or the like
Inventor: WAGNER GUENTHER DIPL ING
IPC: B24B41/06
Filed: 1988-07-20
Abstract: The invention relates to a workpiece carrier for receiving hollow cutlery knife hafts or similarly shaped, preferably camber-profiled hollow parts, for working the edges on grinding and polishing machines, in particular in automatic machine systems. The invention demonstrates a solution in which a plurality of hollow knife hafts or the like are fed to the working machines in the unclamped state, and in cooperation with the positively coordinated movement sequence of the rollers a precisely defined bilateral and simultaneous edge working is performed. For this purpose, interchangeable receiving mandrels, each corresponding to the inner contour of the parts to be worked, are arranged on the base body of the workpiece carrier. The receiving mandrels are so designed that the mounted-on parts are freely movable in the radius of the edge, about the longitudinal median axis. For clamping-in and conveying the parts, a counter strip capable of being guided axially in and out assumes the delimitation of the parts in the end region. In the working machines, the longitudinal movement of the rollers causes the continuous and constant pressing-on of the parts. The opposite oscillating movement of the rollers in the axial direction is transmitted during working to the parts which are freely movable in the radius of the grinding edge, thereby ensuring a precisely defined cambered working of the edges.

Abstract: A method and apparatus provide for relocating a block of data bits from a source location in a memory 15 to a destination location in the memory, where data in the memory is organized and addressed in the form of words and the source and destination locations can occur at different bit positions in different words in the memory. A destination word register 30 receives and stores data in the form of an assembled destination word. A holding register 32 receives and stores a word for subsequent use in the destination word register. Word splitting means 36, 38, 40, 34 enable bits of a word stored in register 32 to be merged with bits of an adjacent word from the source location, thus forming the assembled destination word, in accordance with a degree quantity (bit offset), so that the data in the destination word register 30 is positioned at the proper bit position for writing to the destination location. The degree quantity is a function of the source and destination location boundaries and is preferably expressed in two's complement format. <IMAGE>

Title: Solid dyestuff formulation contg. alkane-di:ol as duct inhibitor - and used for dyeing
Inventor: MISCHKE PETER DR
IPC: C09B67/00
Filed: 1990-05-11
Abstract: Solid dyestuff formulation (I) contains a 4-8 C alkanediol. (I) contains 0.5-20, pref. 1-10 (wt.)% diol(s) and 20-80% dyestuff, pref. a reactive dyestuff. The diol is 2-methyl-pentane-2,4-diol and/or neopentyl glycol; n-butane-1,3-diol; n-pentane-1,5-diol; n-hexane-2,5-diol; or a mixt. of at least 2 of these. USE/ADVANTAGE - (I) is claimed for dyeing materials. The diol inhibits or prevents dust formation and is readily soluble in cold water. In an example, 308 pts. powder contg. 81% 1-methyl-4-methoxy-2-beta-sulphato ethylsulphonyl-benzene (5-azo-4) 3-hydroxy-4-methyl-1-(4-sulphophenyl)-pyrazole, di-Na salt, and electrolyte (mainly NaCl) were mixed homogeneously with 167 pts. Na salt of a naphthalenesulphonic acid/HCHO condensate (deg. of sulphonation 80-120%; average mol.wt. ca. 6500) and 25 pts. 2-methyl-pentane-2,4-diol. The formulation was readily soluble in water and had a filter value of 4. Even after 4 months at room temp. or 4 weeks at 40 deg.C, the dust-free value was unchanged. The reactive dyestuff formulation was useful for dyeing cellulose fibre material, e.g. cotton, in strong fast tones. The dust inhibitor had no effect on the good quality of the dyeing and prints.
