Patent DE-4242036-A1 (DE)
Inventor: HECKING WILLI
IPC: F24H1/18
Filed: 1992-12-12
Abstract: An expansion vessel for heated drinking water has a hollow space (52) which is closed off by a membrane (42) and is connected to a drinking-water heater. A compressed-gas space (54), bounded by a housing (40), adjoins the hollow space (52). The connector assembly (58) is constructed, for connection of the hollow space (52) to an inlet (70) and for direct connection of the inlet (70) to an outlet (72), in such a way that a drinking-water current is generated through the hollow space (52) when hot drinking water is drawn off. For this purpose, the connector assembly (58) has a direct flow passage (76), passing the hollow space (52), between inlet (70) and outlet (72) and furthermore establishes a flow path (86) which runs, in terms of flow, parallel to the direct flow passage (76) and through the hollow space (52). Arranged in this parallel flow path (86) is a suction device (96), by which a suction can be generated by means of the flow of drinking water flowing in the direct flow path, which suction is used to be able to generate, when drinking water is drawn off, a flow via the parallel flow path (86), through the hollow space (52), into a downstream part (72) of the direct flow path. <IMAGE>

Title: Dispenser with spring reservoir drive
IPC: F16N11/04
Filed: 1992-12-18
Abstract: Under uniform conditions an approximately uniform, slow dispensing occurs during the entire dispensing period. The dispenser is reusable. In a compact arrangement, one or more compressed springs are set in motion by a braking device in the form of a cylinder with a flow valve (choke) or similar on a control element.The spring or springs execute an adjustable, slow and uniform expansion motion. The spring exerts a force on the piston (1) of a dispensing container (9) via a piston rod or intermediate element, and the contents of the container are ejected.

Patent DE-4304224-A1 (DE)
Title: Ring-forming tool
Inventor: MERBOLD DIETER
IPC: B21D53/16
Filed: 1993-02-12
Abstract: Particularly in the production of chromium rings for pot edgings and the like, it is necessary to produce chromium rims which differ from the nominal diameters. To avoid the need for a plurality of ring-forming tools for each nominal size of the chromium rims, since these chromium rims may differ only a little from the actual rim diameters of the associated cooking pots (saucepans), provision is made for an adjustable device in which, on a ring-forming tool adjustable segments permit any desired ring diameter to be produced without the need for a plurality of tools; the tool according to the invention has merely to be set in each case. The segment pieces provided therefor are mounted radially displaceably on a baseplate and carry corresponding forming groove pieces which are designed to be individually exchangeable for each ring diameter. <IMAGE>

Patent DE-4321850-A1 (DE)
Inventor: KEMMERER KLEMENS
IPC: B41F21/10
Filed: 1993-07-01
Abstract: The invention relates preferably to a semishell-shaped gripper for sheet printing machines. The object of the invention is to develop a gripper of low weight which is attached without play on the gripper shaft and minimises the slip of the gripper tip on the printing carrier. This is achieved in that the gripper finger (2) which surrounds the gripper shaft (1) in a sector of a circle has congruent cutouts (11) in its side walls (17) in such a way that separate active surfaces (8, 9) are formed at its ends. The active surfaces (8, 9) are assigned to the gripper shaft (1) with frictional engagement and, in conjunction with the resulting force, form a triangle of forces. The gripper holder (4) has on its upper side a depression (12) extending parallel to the gripper shaft (1) and, with the lower edge of a web (16) connecting the side walls (17), forms a releasably positive-locking connection between the gripper holder (4) and the gripper finger (2). The gripper tip (3) has a raised holding surface (15) which has radii (R) which run out at its circumference. <IMAGE>

Filed: 1994-01-27
Abstract: A bitumen/carbon black concentrate (I) contains 1-45 wt.% carbon black (II) and has a Grindometer (RTM) value of less than 50 microns. Concentrates contg. up to 40 wt.% carbon black, e.g. Printex A powder (RTM), were prepd. by mixing bitumen B80 with the powder at 150 deg C. in a LUK 3IInS kneader (RTM). The Grindometer values obtd. (after dilution to 7.5% with more bitumen in a dissolver at 4000 r.p.m.) were less than 10 microns; stirrer speeds of 2000 rm.p.m. or less gave values of above 50 microns.  The 7.5% concentrate was mixed with an asphalt compsn. contg. 7.5 wt.% bitumen, 9.98 wt.% filler, 20.4 wt.% sand and 62.6 wt.% grit, to give a final carbon black content of 0.6 wt.%. The prod. had a crack sensitivity (time taken to reach the inflection in the deflection/time curve) of 6300 secs.; this was increased to 11,000 secs. after accelerated weathering (500 hrs. in a Q-U-V appts. (RTM) at 50 deg C. with a 4-hr. moisture/irradiation cycle). (cf. 2900 secs., falling to 2400 secs. after weathering, with 0.6 wt.% pptd. silica instead of carbon black).

Abstract: A yarn feeder for a textile, e.g. a knitting, machine comprises a rotary spool (2) which is driven by a motor controlled so as to form a yarn reserve in accordance with the requirements of the textile machine. To accommodate changes in yarn consumption or speed of the textile machine which are too rapid for the inertia of the motor to respond to, a yarn gathering device which may have the form of a controllably pivoted arm (3) is provided. The arm is pivoted by a dedicated motor, which like the motor driving the spool (2) is under electronic program control, so as to take up a temporary surplus of yarn in the form of a variable loop (5). In another embodiment the arm is omitted and the yarn surplus is stored on the spool (2) itself, a brush-like braking ring on the spool maintaining tension in the outgoing yarn. An optical sensor arrangement monitors the reserve on the spool to detect yarn breakage. <IMAGE>
