Patent CA-2075202-A1 (CA)
Inventor: FORBERG HANS-JUERGEN
IPC: A61M39/00
Filed: 1991-11-16
Abstract: A nonreturn valve has a housing (1) provided with a central chamber (9) into which open an inlet channel (6) and an outlet channel (7) that may be separated by a seal-ing membrane (10) provided with a flow passage (18). The membrane (10) has a marginal part (16a) clamped in the housing (1), a central sealing part (16b) and a thinner annular wall (17) that links both parts (16a,16b). In order to obtain a nonreturn valve that has a reliable operation even at the smallest differential pressures, a central crater-like sealing formation (13,14), for example, is provided in the membrane (10). The inflow from the inlet channel (6) to the membrane (10) takes place outside the crater-like sealing structure (13,14) and the flow passage (18) of the membrane (10) is located within the crater-like sealing structure (13,14). The thinner annular wall (17) of the membrane (10),that generates a sealing pre-stress, has a shaped cross-section and its open junc-tures (17a,17b) adjacent to the marginal part and to the central sealing part (16b) of the membrane (10) are located at least approximately in the same plane, that coincides with the sealing plane, or is parallel thereto.

Abstract: A method is disclosed far forming a paper web having a law tensile ratio. The method includes the steps of ejecting stock (S) substantially horizontally from a headbox (12), and receiving the rejected stock (S) onto a substantially horizontally disposed looped first wire (14), moving at substantially the same speed and the same direction as the ejected stock (S), The arrangement is such that a first portion of water (18) is removed from the elected stock (S) downwardly through the first wire (14) daring passage of the ejected stock (S) through an initial dewatering zone (20). The partially dewatered stock is sandwiched between the first wire (14} and a looped second wire (22), the wines (14, 22) defining therebetween a secondary dewatering zone (24) for further dewatering the ejected stock. A second and third portion of water (28, 30) are removed downwardly and upwardly, respectively, through the first and second wires (14; 22) during movement of the ejected stock past a curved shoe (26). The curvature of the secondary dewatering zone (24) is reversed such that the wires (14, 22) extend around a curved inverted box (34) connected to a source of partial vacuum (36), so that a fourth, portion of water (38) is removed upwardly through the second wire (22) into the curved box (34). The arrangement is such that a gradual dewatering of the ejected stack is accomplished during passage of the stock (S) through the initial and secondary dewatering zones (20, 24), thereby inhibiting removal of lines from the ejected stock and minimizing the tensile ratio of the resultant web (W).

Abstract: Disclosed is a method to construct a plaza deck/parking structure comprising affixing a porous, water-permeable fabric layer (20) to the top of a plurality of plastic foam panels (14) having a channeled (18) and rib bed surface structure, placing a wa-terproof membrane (12) of top of a base deck (10), placing the plurality of panels (14) being affixed fabric (20) on top of the wa-terproof membrane, and pouring wet concrete on top of the fabric layer (20) and allowing the concrete to cure to a solid layer (22). The fabric layer (20) permits the wet concrete to be poured directly onto the fabric (20) covered foam panels (14) as opposed to solid, heavy concrete slabs being transported to and placed on top of the foam panels (14). The channeled (18) ribbed (16) structure of the foam plastic insulation (14) provides for ventilation and moisture removal which leads to better wearability of the insulation material in the plaza deck/parking structure. Further disclosed is a plaza deck/parking structure made according to the above methods.

Title: Hair iron for straight-perming
Inventor: NAKAMURA TETUGI
IPC: A45D2/00
Filed: 1992-12-31
Abstract: ABSTRACT        A hair iron is designed to be used in straight-perming hair, especially straight-perming frizzled hair.  The hair iron comprises a grip part and pressing members.  Opposing surfaces of the pressing member for clasping and pressing hair have uneven faces which match each other.  The uneven faces may cover the entire opposing surfaces of the pressing members or parts of them.  The uneven faces give relatively large pressure on hair.  Repetition of pressing and releasing hair with shifting the iron on the hair from the root to the tip causes the hair to be pressed in multiple directions so as to be deformed into a tiny waveform.  Combining regular treatment with perming lotion, the repetition, and sliding the hair iron frictionally on the hair from the root to tip to stretch the hair makes the hair straight tidily.

Abstract: A magnetohydrodynamic angular rate sensor is described. A housing (30) supports first and second fluid proof masses in respective coaxial annular channels (11, 17), permitting rela-tive motion between the proof masses and the housing. First and second magnets (12, 18) asso-ciated with each annular channel (11, 17) result in an electric potential being generated across each channel proportional to the relative circumferential velocity between the proof masses and the housing. The annular channels ace connected together to form a continuous pumped fluid circuit which introduces a radial flow velocity in each channel. At low rotational frequencies, a circumferential velocity component is induced in the proof masses due to Coriolis acceleration which results in a measurable electrical voltage across the annual channels.  The low frequency response of the sensor is therefor extended to lower frequencies.
