Title: Articulated lumbar support for a seat
Inventor: NEALE COLIN G
IPC: A47C7/46
Filed: 1992-06-02
Abstract: Abstract of the Disclosure A user adjustable lumbar support apparatus for inclusion in a seat back, comprising an essentially rigid back plate having front and rear surfaces and adapted to extend vertically within a seat back, a front plate having a front and back surface and having an orthotic lumbar support contour at its said front surface, the contour preferrably being generally concave side-to-side and convex top-to-bottom, and a mulit-chambered fluid actuator including at least a pair of independently inflatable chambers arranged vertically one chamber above the other, together with elastic means supporting the actuator and the front plate in assembled relationship to the back plate with the chambers between  aid plates to accommodate relative motion between the plates as the chambers are inflated and deflated. The fluid actuator preferably is a distendable chamber member containing separated enclosed fluid receiving chambers. Fluid under pressure   is admitted and vented separately to and from each chamber to alter the positional relationship of the front plate to the back plate so the lumbar support contour can be adjusted to a position giving optimum support at a desired elevation along the seat back. An elastic strap confines the fluid chamber member between the plates, such strap being attached at its ends to one of the plates and engaged with the other plate to urge the plates together with the fluid chamber member between the plates. There is a resilient support for the back plate about a generally vertical axis of the seat back to allow compliant rotational motion of the support assembly within the seat back in response to like motion of the torso of a person seated against the seat back.

Title: Direct access storage device with independently stored parity
Inventor: MANKA PAUL S
IPC: H03M13/27
Filed: 1990-12-05
Abstract: A failure independent, fault tolerant Direct Access Storage Device (DASD) storage subsystem including a Disk Control Unit (106) and a number of Physical Devices (211, 212) is provided with a parity Generator (303) for generating a parity for system records as the system records are transferred between the storage subsystem and a CPU (101) of a data processing system. The parity is stored on a different unit so that if one unit containing portions of a system record becomes unavailable, the unavailable portion of the record is reconstructed during transfer to the CPU from the remainder of the record and the parity. The storage system of the invention can accommodate variable length data records without requiring operating system modifications.
Patent CA-2071163-A1 (CA)
Title: Fire-Retardant Chemical
Inventor: TROCINO FRANK S
IPC: C08L61/20
Filed: 1992-06-12
Abstract: A fire-retardant composition for rendering a combustible hydrophilic substrate resistant to combustion and flaming is disclosed.  Also disclosed are processes employing said composition for rendering a hydrophilic substrate resistant to combustion, as well as structural material made fire-resistant by such a process.  The composition is a thermoset formed by combining two resins, which can be either made and stored separately for long periods until use or stored as a partially polymerized liquid mixture.  The resins are water soluble and heat-curable to form the thermoset.  The first resin comprises polyols derived preferably from a carbohydrate such as maltodextrin having substituent groups occupying a portion of the available hydroxyls derived from monoammonium phosphate, urea, phosphoric acid, and glyoxal.  The second resin can be a methylol-melamine-formaldehyde, methylol-urea-formaldehyde, or methylol-phenol-formaldehyde formulation.  When cured on a hydrophilic substrate, the fire-retardant composition becomes crosslinked and covalently bonded to molecules of the substrate.  Also, P-and N-containing constituents critical for fire retardancy are covalently bound in the thermoset, rendering these constituents non-leachable.  As a result, fire-retardancy is maintained throughout the useful life of the substrate, even when exposed to the weather.

Title: Method for detecting petroleum and mineral deposits within the arctic shelf
Inventor: KRASNOV YURI
IPC: E21B49/00
Filed: 1992-07-29
Abstract: ABSTRACT     This  invention  presents a method  for  detecting mineral,  and particularly  petroleum, deposits  by  means  of analyzing  polar (Arctic) ice movements, dispersion, arrested  motion and ice pile-ups. These processes exibit a certain regularity in ice  dynamics which  corresponds  to  the  natural occurrence  of  mineral  and petroleum deposits.  The main indicator pointing  to the location of  oil deposits  are the  places where  polar ice  movements are arrested  and  subsequent pile-ups  occur.  The  analysis of  ice movements  and ice  dispersion helps  to identify the geological structures containing oil-bearing formations. The proposed method can also be used to detect other mineral deposits.

IPC: F16B13/06
Filed: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE          DOWEL JOINT SYSTEM FOR CONNECTING WOODEN ELEMENTS A system for fastening a dowel to a wooden element includes a drilling assembly for forming a blind hole in the wooden element which includes a first portion which is cylindrical and a second portion which tapers outwardly in frusto conical shape from the lower end of the first portion. A dowel having initially a cylindrical shape is inserted into the blind hole and the expanded outwardly into the frusto conical portion. The expansion can be carried out by a tapered plug which is forced into the end of the dowel, by a wedge member which is forced into slits in the end of the dowel or by expansion of the dowel itself from an initial compressed position by absorption of moisture from an adhesive. The drilling is effected by a compound drilling assembly which includes a first and second drilling element, the latter being movable axially relative to the former with the axial movement causing the latter to move outwardly along the frusto conical shape to form the second frusto conical portion after the first element drills to the required depth of the hole of the bore.

Abstract: Épandeur de fumier et méthode d'épandage de divers types de fumier de consistances variées. L'épandeur et la méthode d'épandage visés obéissent à un principe selon lequel plusieurs auges de forme allongée sitées longitudinalement dans une caisse mobile amènent le fumier à un point d'évacuation pour le transférer à un mélangeur qui épand le fumier dans un champ ou dans un endroit semblable. On observe un phénomène de glissement au lieu d'évacuation, selon lequel la quantité de fumier se trouvant à cet endroit est supérieure à la vitesse d'évacuation du mélangeur. Ce glissement se produit entre le fumier et les lames rotatives au point d'évacuation pour éviter que le mélangeur ne soit surchargé par le fumier qui est répandu.
