Title: Manhole cover locking system
Inventor: WESTHEIM PER T
IPC: E02D29/14
Filed: 1991-10-31
Granted: 1997-12-23
Abstract: A manhole cover securing and locking system is disclosed by which a manhole cover (3)  may be secured and locked to a corresponding manhole frame (2) so as to prevent unintended removal of the cover while permitting the intended removal. The locking system comprises a spring member (5) which at  one end is attached to or made unitary with the underside of the cover (3) and at its other, free end has a nose or similar protruding part (6) intended to engage under an inwardly protruding frame rim (7) when the cover is positioned in its covering position. The spring member (5) is substantially in the form of a "U" or a "V" the limbs of which extend substantially at right angles to the periphery of the cover.  Beads or similar protrusions (9) are provided on the inner wall of the frame below the frame rim (7) to engage with the spring member nose (5) and prevent rotation of the cover in the frame.
Patent CA-2054880-C (CA)
Inventor: MAEDA SHIGEMI
IPC: G11B7/085
Filed: 1991-11-04
Granted: 1997-07-08
Abstract: An information recording and reproducing device has a first recording-clock-generation circuit which generates a clock based on pre-recorded information on a magneto-optical disk, a second recording-clock-generation circuit, and a switching circuit. The switching circuit selects a first recording clock when recording is of discrete information, and selects a second recording clock when recording is of successive information. Moreover, in the present device, a first reading clock as well as a second clock are used as a clock for reading out the reproduced data from the magneto-optical disk. The second reading clock having a reference frequency is generated by a second reading-clock-generation circuit, and is used for reading out successive information such as music information. The first reading clock insynchronization with the reproduced signal is generated by a first reading-clock-generation circuit, and is used for reading out discrete information such as computer-use data. In addition, in the case of discrete information, it is possible to start a recording/reproducing operation immediately after an optical head reaches a desired position, thereby permitting a shortened access time.

Inventor: DIEM ECKEHARD
IPC: A21C9/08
Filed: 1990-10-30
Granted: 1997-01-28
Abstract: In a process for folding dough sheets, in particular strudel dough sheets, at least one dough sheet is folded inward in opposite directions in at least two consecutive folding operations along parallel fold lines, and the exposed edges of the dough sheet that are parallel to the fold line come to lie within the projection of the folded dough sheet, after which the dough sheet folded this way is tucked on a first end along a line running crosswise to the parallel fold lines.  Starting from the folded dough sheet's other end that is opposite in the direction of the parallel fold lines, tucking is performed at least twice opposite the direction of the first tuck, so that a folded edge of the product tucked at least twice comes to lie above the tucked, first end.    In a device for performing this process, there is attached, to a conveying device (1), a first folding station (8) with folding flaps that can be pivoted around pins parallel to conveying direction (11), and in the conveying direction, after first folding station (8), a flap (22) that can pivot around a pin running crosswise to conveying direction (11) is attached and the conveying device comprises a transfer point to a device for multiple tucking of the exposed end of the folded dough sheet.

Granted: 2003-09-09
Abstract: The present invention relates to an absorbent body (3) which is intended to form the absorbent element in an absorbent article, such as a diaper, an incontinence guard or a sanitary napkin, and includes a first absorbent layer (16) which, in use, is intended to face towards the wearer, and a second absorbent layer (17) which is intended, in use, to face away from the wearer. According to the invention, the absorbent body (3) includes at least two mutually different cellulose fluffs, wherein the major part of the fibre structure of the first absorbent layer (16) is comprised of a first type of cellulose fluff having low liquid-spreading ability and a critical bulk which exceeds 8 cm3/g at 2.5 kPa, while the major part of the fibre structure of the second absorbent layer (17) is comprised of a different type of cellulose fluff having a critical bulk beneath 8 cm3/g at 2.5 kPa and a higher liquid-spreading ability than the cellulose fluff in the first absorbent layer (16). The second absorbent layer (17) will therefore be highly capable of draining liquid from the first absorbent layer (16). The second absorbent layer (17) includes superabsorbent material which is admixed generally uniformly in the cellulose fluff within at least one area of the layer (17).

Title: Multi-lavatory system
Inventor: BARNUM THOMAS G
IPC: E03C1/01
Filed: 1994-04-21
Granted: 1998-06-30
Abstract: A multi-lavatory system is preassembled to facilitate efficient installation with a minimum of connection points.  The multi-lavatory system is connected to a single fluid supply line and a single drainage line.  A fluid supply network conducts water from the single fluid supply line to a plurality of lavatory stations.  Similarly, a drainage network conducts waste water from the plurality of lavatory stations to the single drainage line.  Additionally, the multi-lavatory system includes a unitary lavatory subassembly having interconnected but spaced sink regions.  Each sink region is disposed in one of the lavatory stations and is bounded at a frontal area by an upstanding contoured wall that creates an independent washing zone.  This facilitates efficient production of the unitary lavatory subassembly and overall multi-lavatory system while providing each user of the system with a sense of privacy in their own independent washing zone.
