Patent DE-632875-T1 (DE)
Inventor: HANSSON BENGT H
IPC: F24C15/00
Filed: 1993-03-09
Abstract: PCT No. PCT/SE93/00204 Sec. 371 Date Oct. 17, 1994 Sec. 102(e) Date Oct. 17, 1994 PCT Filed Mar. 9, 1993 PCT Pub. No. WO93/18349 PCT Pub. Date Sep. 16, 1993The invention describes a device for cooking food without frying fat where touchable parts are kept well cooled and the food products can be taken out without the device having to be dismantled or tools being used and where the amount of watervapour in the food processing compartment can be regulated in such a way that optimum process quality can be reached. The invention solves these problems by the food processing taking place in the rotating food processing compartment (8) which is flushed by hot air driven by a fan (12) placed inside the oven compartment on five sides surrounded by the shell (2) and the sixth side of which is covered by a component consisting of the heat shield (4) and the cooling-air duct (5) broken through by the rotatable basket holder (6) with the basket (7) and with their corresponding heat shields (20,21) and cooling-air ducts (22,23). Cooling air is pressed by the fan system (13) into the housing (2) and further in through the openings (15) into the cooling-air duct (18) of the front panel. The food product is reached by withdrawal of the basket (7) by means of the handle (46) without any opening procedure. The regulation of the amount of water vapour necessary for the quality of the food product is done by moving the ventilation slide (58) which in the same movement opens or closes the openings in the ventilation device (47) to the inlet opening (52), to the injector (56) where a part of the air enters and passes through to the ejector (57) where the air which enters via the injector (56) together with excess water vapour exits from the oven compartment (1) and is mixed with remaining cold air from the cooling-air fan (3) and continues into the surrounding air.

Abstract: The invention is a blister package for containing frangible dosage forms while protecting the dosage forms from damage during transport and opening of the package. A blister sheet defines one or more recesses in which frangible dosage forms are disposed and a peelable sheet of lidding material overlies the recesses to cover the dosage forms therein. The dosage forms engage each recess to prevent shifting of the dosage form during transport. Indicia on the blister package directs the user with regard to the procedure for opening the package without damaging the dosage forms. Unsealed areas in the package, which provide a portion of lidding material which the user can grab to peel open the package, are provided with dimples which hide the grabable portion of lidding material from children.

Title: Reformer exercise apparatus anchor bar and carriage stop assembly
Inventor: ENDELMAN KEN
IPC: A63B26/00
Filed: 2004-11-24
Abstract: A reformer exercise apparatus has a head end and a foot end and a pair of spaced apart parallel track members, a movable carriage mounted on the track members for movement between the head and foot end. One or more springs are connected between the carriage and an elastic member anchor bar and carriage stop assembly at the foot end. The anchor bar and carriage stop assembly adjustably positions the carriage, the anchor bar and the elastic members on the tracks to accommodate a wide range of user heights. Each end of the anchor bar is disposed in an elongated slot formed in each track member. The elongated slot has spaced gear teeth shaped openings defining spaced anchor bar stop or lock portions. The anchor bar can be moved between lock portions only when rotated to an unlocked position wherein the bar, coupled to the carriage, can slide along the track within the slot. In addition, the assembly maintains the carriage and anchor bar a predetermined distance apart when the anchor bar is in the unlocked position and maintains a minimum distance between the anchor bar and the carriage when the anchor bar is in the locked position.

Abstract: A lock assembly (10) includes a first member (12) and a second member (14) including complimentary shaped protrusions (13) and recesses (15) that mate with one another. A locking assembly is housed in the first member (12). The locking assembly includes an electromechanical actuator (18) with a shaft (20) and a locking element (22) arranged to move along the shaft (20) between a locked position and an unlocked position. The locking element (22) is formed with a recess. In the locked position, a locking bolt (16) passes through both first and second first member (12)s and a latch member (26) is received in the notch (28) but is not received in the recess of the locking element (22) so that the locking element (22) prevents movement of the latch member (26) and the locking bolt (16). In the unlocked position, the latch member (26) is received in the recess of the locking element (22), thereby permitting movement of the locking bolt (16).

Abstract: A double pump adapted for use as an artificial heart includes two ventricle-simulating chambers that are provided with respective inlets and outlets having valves incorporated therein and that are separated by a common partitioning wall structure. The wall structure has sections that are driven away from each other to reduce the volumes of respective ventricle chambers and expel liquid from the chambers through the outlets. The wall structure can also move laterally in response to differences in pressure between the chambers and hence change the volumetric ratio between them. This ensures a balanced action between the two halves of the heart- simulating pump during a systole phase and a diastole phase. The link mechanism is actuated by a cord through a motor, although only in one direction in the pressure phase, and hence the aforementioned changed volumes are readjusted primarily through the pressure exerted by the inflowing fluid. The pump may also include a variable volume atrium-simulating chamber communicating with the inlet to each ventricle-simulating chamber and having volume that is controlled in part by an externally acting gas pressure that varies in accordance with changes in the volumes of the ventricle chambers.

Abstract: An apparatus and method for continuously manufacturing optical fiber cable in which optical fiber is encased by an hermetically sealed homogeneous metal tube formed from flat metal strip (11). A first assembly of mating rollers (26, 28) having successively different shapes forms the flat metal strip into a partially formed tube (12) having a longitudinal gap. Optical fiber (13) is guided through the gap to lie within the partially formed tube. The tube (12) is then closed by a second assembly of mating rollers having successively different shapes. A laser beam is used to weld the seam closed without filler metal and without heat shielding between the seam and the optical fiber. The finished tubing with optical fiber therein is sunk by being drawn through wire dies to reduce the diameter. A wheel draws the tubing through the apparatus at constant speed to effect a uniform weld line. In another embodiment, an introducer tube of smaller diameter than the hermetically sealed homogeneous metal tube extends within the metal tube to about the point of tangential approach of the metal tube to the wheel. Gas flows through the introducer tube to carry the optical fiber by viscous drag and blow the optical fiber against the outer circumference of the metal tube as the metal tube wraps around the wheel.
