Abstract: A brewing unit 1 for a coffee machine comprises a brewing cylinder 2 and a piston 5, 13, wherein the brewing cylinder 2 and the piston 5, 13 are movable relative to one another in the axial direction. An activatable seal 12, 18 or seal assembly is provided to seal the piston 5, 13 against the inner wall 3, 15 of the brewing cylinder 2. The seal 12, 18 is activated by an axial movement of piston 5, 13 with respect to the brewing cylinder 2. Under compression when activated, to form a seal between piston 5, 13 and brewing cylinder inner wall 3, 15, and which seal 12, 18 or seal assembly. When not activated, the seal 12, 19 is either not at all, only under low compression contact with the element.

Abstract: A fence winding reel device including a rotatable frame with a slotted groove along its length and a pair of curved plates, together which comprise an expandable core. In an expanded position, a pair of expanders holds the pair of curved plates away the frame. An end of fence wire is placed into the slotted groove of the frame. The reel device may be connected to any standard earth auger mounted on a skidsteer loader. As the auger motor rotates, fence wire is wound around the expandable core to form a wound fence coil. Removing the fence coil from the reel device involves contracting the core, which narrows the distance between the expanders and the frame, and sliding the coil off the core and out of the frame groove. The reel device may also be used to lay down fence wire by operating the auger motor in a reverse rotational direction. A hydraulic core expander is also depicted.

Abstract: A downhole mud motor (100) is disclosed which has an improved bearing mandrel (107) and a bearing stop (105) to transfer a larger percentage of the weight of a drill string to the bit. Also improved sealing systems (113) (114) (220) (515(706) for the transmission section and bearing section (116) (310) (117) (118) (119) prevent drilling mud from entering critical components. A piston stop is provided to prevent the piston from damaging other parts as the piston moves under pressure. Compensating pressure assembly (204) preferably including a disk (1408) is placed in the lower housing (108) to prevent pressure from building up in the bearing section (308). A combination of grooved ball seats (130) and circumferentially spaced balls (127) are provided in the transmission section (200) (207) to allow for greater flow of lubricant around the ball bearings.

Abstract: A coffee bean container for an automatic coffee maker comprising a receptacle (2) for storing coffee beans, with an output shaft (4) via which coffee beans in the receptacle (2) can be supplied to a grinding mill. The coffee bean container has a coupling ring (7) disposed coaxially to the output shaft (4) for connecting the coffee bean container (1) to an automatic coffee maker. The coffee bean container (1) has a closure unit (12) for closing the output shaft (4) which has at least one closure element (13, 14). The at least one closure element (13, 14) is supported about a pivot axis parallel to the axis of the output shaft (4) and pivotable between an open and a closed position. The closure unit (12) includes a mechanical drive which mechanically couples the closure element(s) (13, 14) to a rotational movement of the receptacle (2) which moves the closure element(s) to the open position or closed position.

Abstract: A tape roller bearing is provided that prevents the development of an air film between the roller surface and the tape. The spool surface is made from porous material so that air flows through the spool surface. The porous material vents air uniformly over the roller surface, and the tape remains in direct contact with the roller, even at high speed. The speed of the tapes movement can be determined by measuring the speed of movement of the spool surface using an encoder disk and an encoder module.

Abstract: A shoulder harness is made of straps forming a figure eight having a criss-cross strap configuration across a worker's back. Two adjustable sized loops are formed which hang under the worker's arms. A hook is threaded into each loop. A wide tension buckle is mounted from the hooks via carabiners, thereby centering the tension buckle in front of the worker. A web lift strap about six inches wide is threaded into the tension buckle. A second worker threads the opposite end of the lift strap into his tension buckle. The lift strap is placed under a load and carried by the two workers over rough surfaces that dolly wheels couldn't handle. Alternate embodiments include a central ring to join three or more workers' straps together, a hip carry mode which joins the two loops at a hip, and a two-strap mode for carrying loose objects.

Abstract: Both positive and negative wind loads acting on the surfaces of standing seam roofing often exceed the design capabilities of a particular metal roof, causing the standing seam interlocking vertical seams to disengage. This often results in the roof panels blowing off the roof, causing damage to the roof, the building contents and possible danger to people in the vicinity. A transverse bar is provided across the standing seams of the metal roof. Clamps hold the transverse bar onto the standing seams. At the midsection of each flat panel section of the metal roof a brace descends from the transverse bar. The brace must have a flexible foot member to press down on the panel, otherwise the brace would puncture or otherwise damage metal roof panel. The brace may have an adjustable height adjustment mechanism. Various clamp, bar and foot embodiments are disclosed, all of which provide a structural anti-lift bracket on the roof panel.
