Patent DE-3716426-C1 (DE)
Inventor: W R DIPL-ING LOHR KARL
IPC: F17C1/02
Filed: 1987-05-15
Granted: 1988-10-20
Abstract: A double-walled pressure vessel comprises an inner shell impermeable to compressed gases with a curved inner floor and an outer shell impermeable to compressed gases with a curved outer floor, and a double-walled stub-type access hole. A space is provided between the inner and outer shells and between the walls of the stub-type access hole. The stub-type access hole (2), a manometer well (3), an inspection pipe stub (4), a pump recirculation pipe stub (5), a gas displacement pipe stub (6), a thermometer well (7) and a level-indicating pipe (9) are arranged in the part of the floor (1) of the vessel subjected mainly to tensile stresses but to low flexural stresses. In addition to the stub-type access hole, all the other connecting pipe stubs are of double-walled design. Other double-walled pipe, namely a safety pipe (11), a rinsing pipe (12), a leak-detection pipe (13), an extraction pipe (14), an emergency extraction pipe (15), a filling pipe (16) and a leak space pipe (17) are provided in the region of the outer shell (10) subjected to low tensile stresses. All these pipe stubs are attached to the pressure vessel by liquid-tight and gas-tight welds. A space is left between the inner and outer walls of all pipe stubs, and all spaces communicate with one another.

Title: Axial fan
IPC: F04D29/056
Filed: 1988-04-13
Granted: 1989-09-28
Abstract: The fan has moving blades which are mounted with their spar in a support ring arranged coaxially in an impeller hub. The mounting comprises an axial bearing, against which the spar is supported with a nut on the side of the support ring facing away from the blades. The axial bearing is designed as an annular disc made of a self-lubricating sliding bearing material. The annular disc is supported, with its side facing away from the spar nut, on a spherical disc located on the support ring. An arrangement for blade adjustment during operation engages on the spar. During operation in the open position, a centrifugal moment acts on the moving blades. As a result of the relatively great static friction coefficient of the bearing material, the axial bearing is self-locking. The restoring moment is thus absorbed by the bearing. The blade adjustment arrangement remains free of the effect of the restoring moment. Compensating weights can thus be dispensed with so that the impeller hub can be of axially short construction. A lubricant supply in the impeller hub is likewise no longer necessary.

Title: Dispensing device for a pair of shafts of a vending machine
IPC: G07F11/24
Filed: 1988-06-18
Granted: 1989-06-22
Abstract: In a dispensing device for a pair of shafts of a vending machine, especially for bottles or cans, products of the right-hand or of the left-hand shaft (1, 2) can be dispensed selectively. Provided for the pair of shafts (1, 2) is a pair of identical dispensing members (8, 9), the axes of rotation (10, 11) of which are offset relative to the alignment of an intermediate wall (6). The directions of rotation (R, L) of the dispensing members (8, 9) are in opposition, in such a way that each dispensing member (8, 9) pivots the product to be dispensed by it in the direction of the other dispensing member (9, 8). During the dispensing of a product, a blocking rod (18) in alignment with the intermediate wall (6) is pivoted in the direction of the other dispensing member as far as a stop (21, 22). It holds the product (F, D) to be dispensed, until the next upper product is supported by the blocking surface (12). <IMAGE>
