Title: Sleeve and cylinder assembly and method of assembling
Inventor: WIEMAN ROBERT L
IPC: B41N7/00
Filed: 1959-01-26
Abstract: 896,083. Rollers. MINNESOTA MINING & MANUFACTURING CO. Jan. 26, 1959 No. 2785/59. Class 42 (2). [Also in Group XVI] A method of mounting a cylindrical sleeve on a generally solid, resilient cylindrical body having a normal outside diameter larger than the inside diameter of the sleeve and at least one passage or cavity extending therethrough comprises creating conditions within the passage or passages causing the reduction in diameter of the body throughout its length, applying the sleeve to the body while the body is retained in its contracted condition, and removing the conditions creating distortion of the body, whereupon the sleeve is tightly frictionally retained on the body. A metal core 18 is surrounded by a rubbery body 20 and provided with projecting spindles 24. The passages 22 extend to both ends of the cylinder. In order to apply a rigid sleeve the passages are closed at one end by a washer 36, while at the other end a vacuum cup 26 is fitted over the spindle and communicates with a vacuum pump through a nipple 30 and tube 32. When vacuum is applied, the body 20 contracts to a smaller diameter, the sleeve is placed in position, and the vacuum released, the body expanding to engage it firmly. In other forms, the passages may be grooves of semi-circular section opening against the core, or grooves in the core opening outwards. The roller may be used as an inking or damping roller in a printing- machine. The resilient body may be of natural or synthetic rubber, rubbery polymers, rubbery compositions of glue and gelatin, synthetic resins, or vulcanized plant oils. The passages may terminate short of the ends of the body, a passage through the end of the spindle or core leading to a connecting passage. The roller may be formed by applying to the core layers of rubber, and after the first layer rods of metal, coated with polytetrafluoroethylene polymer to prevent sticking of the rubber, are pressed into said layer. After application of the second layer, compression with wet nylon tape, vulcanization and cooling, the rods are removed.

Title: Circuit arrangement for the serial storage and extraction of alphanumeric information
Inventor: LOGISCH HELMUT
IPC: H03M9/00
Filed: 1969-01-17
Abstract: 1,248,542. Data storage. KOMBINAT ZENTRONIK VEB. 17 Jan., 1969, No. 2791/69. Heading G4C. Characters of 4 or n (greater than 4) bits are transferred to and from a store, e.g. magnetic drum, using series-parallel and parallel-series converters for the 4-bit characters and a shift register and first counter for the n-bit characters, the first counter having a capacity equal to the number of n-bit characters per word, a common counter counting 4 and n in the case of 4 and n bit characters respectively. The converters use gates controlled by two stages of the common counter, which is basically a 3-bit binary counter, to convert a 4-bit character from parallel to series on transfer from an arithmetic unit to a track of a magnetic drum, and from series to parallel on transfer in the reverse direction. The shift register converts a 6-bit character from the drum from series to parallel and supplies it to a data carrier or printer. It can also convert such a character obtained, optionally via a code converter, from a data carrier or a keyboard on the printer, from parallel to series to write on the drum. A flip-flop, controlled manually or by programme, selects whether 4 or 6 bit characters are to be handled, and inter alia controls the common counter so that in the case of 6-bit characters it skips counts 4 and 5. The first counter is driven by the high order stage of the common counter and also by an extra pulse at word beginning. The all-zeros state of the first counter is used to gate shift pulses to the shift register.

Filed: 1917-02-28
Abstract: 113,496. Wybaillie, F. M. A., and Peyman, A. Feb. 28, 1917. Cut-out arrangements; bulbs; caps; filaments; supports for.-In a lamp for series connexion, a device for substituting an equivalent resistance comprises a fuse controlling a switch for the resistance and arranged to be connected in circuit on breakage of the filament. In the arrangement shown, supports 9 for the filament are alternately rigid and elastic in each spider, and each filament length joins supports of both kinds. When the filament breaks, a support springs into contact with one of two rings 15, carried by arms 14 on the hollow stem 7. Some of these arms are preferably integral with wires 21, 22, traversing the stem and twisted together where they pass through its lower sealed end. One wire 22 connects the two rings 15, and the other wire 21 extends from the outer ring to the fuse 16 at the outer end of the stem 7, which passes through the lamp-foot into the space within the screw cap. A contact 17 is attached to the fuse 16 and to a spring arm 18, and when released by the fuse engages the back of the central contact stud of the cap. The substitutional resistance, which is wound around a cylindrical part of the lamp foot, is thus switched into circuit. Breakage oi the stem also cuts out the lamp, by allowing the wire 21 and contact 17 to rise without blowing of the fuse.

Title: Improvements in measuring elastic properties of materials
IPC: H01B3/44
Filed: 1935-02-01
Abstract: 450,880. Testing physical qualities of materials. HENNING, H. J., 7, Pistorisstrasse, and KNOTE, R., 131, Dieskaustrasse, both in Leipsic, Germany. Feb. 1, 1935, No. 3364. Convention date, Feb. 14, 1934. [Class 106 (ii)] The force with which a pad of material such as textiles, hair, paper, cotton wool &c. resists compression comprises a momentum motor device, such as a pendulum adapted to give repeated blows to the specimen, the work done in damping the movement being measured by the aggregate of several compressions or extensions. A pendulum 1 is suspended from a spindle 121 mounted in ball bearings 2 carried by the frame and has fixed to it and projecting above the bearing a bracket 3 with a pivot 3<1> carrying an arcuate arm 4 with a finger 5, the arm having limited freedom of rotation and being held normally in the position shown by springs. In the path of the finger 5 is one arm of a double-armed lever 12 mounted on the spindle 12<1> and to which is fixed the rod 6 of a piston 7 working in an arcuate cylinder 8 adapted to receive the specimen. A weight 13 balances the piston and a stop 13<1> limits movement of the lever in one direction. To the arm 4 is connected a finger 10 bevelled at the free end and in whose path is a roller 11. The specimen is placed in the cylinder and the pendulum is swung to the mark 50 on the scale 9 and released. When it reaches the vertical position shown, the finger 5 strikes the lever 12 and continuing the swing compresses the specimen until it reaches say the mark 15 on the left of the scale. In that position of the mechanism, the finger 10 strikes the roller 11 and is deflected disconnecting the pendulum from the lever 12 which swings back to normal. The pendulum swings left say until the mark 45 and then back say to 41. During the next swing to the left the specimen is compressed again and so on until on swinging to the left the mark 15 is not reached when the test is over. The number of swings made is a measure of the resilience of the specimen. The pendulum may be made to act on the specimens to apply tension to it. A flywheel may be made to act on the specimen in a similar way.

Class 142(2) A double-lift open-shed dobby mounted under the healds is controlled through Bowden cables by pattern mechanism situated outside the loom frame; the heald can be aligned mid-way between their extreme positions for inspection and repair of the warp. Dobby, Fig. 1. Pairs of levers 19 coupled to the heald frame by links 20 have their inner ends coupled by links 18 to baulks 17 permanently engaged with sliders 14 by means of roller and slot couplings 16, 15. Hooks 13 pivoted on the sliders can be brought into the path of draw knives 5 by rockers 11 set by the pattern mechanism through Bowden cables 23; locking bars 10 are withdrawn from teeth on the rockers during the setting period. Levelling healds, Fig. 1. The levers 19 pivot on rings c supported by bars, a, b which are normally spread apart by wedges (not shown) inserted between them. To bring all the healds to the same level, the wedges are withdrawn by rack and pinion mechanism operated by a hand lever, thereby freeing the rings c for vertical movement; the hand lever also raises bars w, whereby those healds that were down are lifted halfway, and those that were up drop until their levers 19 rest on the bars w. Pattern mechanism Fig. 5. Feeler needles 26 are lifted by a crank 28 whilst the pattern cards are being advanced by cylinders 22. If a needle encounters a hole in a card, a pusher 29 rocks a deflector 27 to bring the upper end of a double hook 24 into the path of an upper draw knife 25, otherwise the hook remains in the path of the lower knife. The hooks are carried by sliders to which the cores 23 of the Bowden cables are attached.
