Title: Reciprocating yarn guide drum with smooth passage in both directions - has structured intersecting grooves with different pitch angles
Inventor: KUESTERS GERARD
IPC: B65H54/48
Filed: 1992-11-10
Abstract: The yarn guide drive drum, to give the yarn guide a reciprocating movement during bobbin winding, has angled grooves to move the guide. The intersecting groove sections (6,7) at the centre plane (M) of the drum (2) are aligned at different pitch angles (alpha, beta). The groove section (6) at the intersection zone is shallower than the other groove section (7), and has a smaller pitch angle (alpha) that the other pitch angle (beta). The pitch angle (alpha) of one groove section (6) is 10-15 deg., and pref. about 14 deg. The pitch angle (beta) of the other groove section (7) is 16-20 deg., and pref. about 17 deg. USE/ADVANTAGE - The drum is for the operation and movement of the yarn guide during bobbing winding, to move it forwards and back along the bobbin through spiral grooves on the drum mantle. The groove structure of the drum gives a smooth passage in both directions, even when winding at high speeds, for working cylindrical and slightly coned bobbins.

Inventor: MERKEL WILFRIED DIPL ING
IPC: B60S1/38
Filed: 1993-06-22
Abstract: The proposal is for a wiper blade which is used for cleaning windows on motor vehicles. The wiper blade comprises a multisection supporting-bow frame to which a driven wiper arm is coupled and on which an elongate wiper strip is held, which wiper strip is made of flexible material, is held such that it is guided by holding claws arranged on frame sections and, seen in cross-section, has a strip spine which is grasped by a plurality of holding claws and protrudes with end portions over the holding claws. Connected to the strip spine, via a web, is an elongate wiper lip which rests on the window to be wiped, and arranged in a longitudinal recess in the strip spine is a flexible reinforcing rail, the length of which corresponds approximately to the length of the wiper strip, securing means holding the wiper strip on the supporting frame and the reinforcing rail in the strip spine. A particularly simple, preassembled exchangeable wiper strip results if the longitudinal recess in the wiper-strip spine is designed as a through-channel which is closed all around and the cross-section of which is matched to the cross-section of the reinforcing rail, if, furthermore, the reinforcing rail has, on at least one longitudinal side, two widened portions which are arranged spaced apart, protrude partially over the cross-section and form the securing means and the distance between them is larger than the width of a holding claw in the longitudinal direction of the wiper strip, and if in ...

Title: Hot-water through-flow container for coffee machines
Inventor: NEUMANN RITA
IPC: A47J31/54
Filed: 1993-07-06
Abstract: The object of the invention is to develop a novel hot-water through-flow container such that most commercially available coffee machines can be equipped with the novel hot-water through-flow container with few alterations. Through inflow of the hot water of a coffee machine in the novel hot-water through-flow container, the water container is filled with hot water through the hot-water rising pipe until the novel slot-shaped water siphon is under water and thus the hot coffee water is able to flow to the coffee filter as a result of suction, with the cooperation of the air suction slot situated at the upper end of the novel hot-water through-flow container. By virtue of the novel slot-shaped water siphon, the hot-water through-flow container is shaped especially flat. The slots of the siphon can also serve the same purpose through small pipes bent side by side.

Title: Hand drill
Inventor: MAYER HEINRICH DIPL ING
IPC: B25F5/00
Filed: 1993-12-13
Abstract: The invention relates to a hand drill with cooling fan. In the case of such hand drills or hammer drills, soiling of the surrounding area occurs again and again during work, leading, especially in low-dust rooms, to laborious extra work. To avoid such extra work, a dust-collecting receptacle (3), which is airtight and of bellows-like design at least in the region of the drill bit (2), is therefore placed onto the drilling spindle (1) of the hand drill, which dust-collecting receptacle (3) is connected to a dust bag (5) detachably fastened to the machine housing (4). At the dust bag, the cooling fan integrated in the drill is used for extraction. As a result, the soiling of the surrounding area during drilling work is largely avoided without additional effort. <IMAGE>
