Abstract: PCT No. PCT/FI91/00064 Sec. 371 Date Sep. 3, 1992 Sec. 102(e) Date Sep. 3, 1992 PCT Filed Mar. 6, 1991 PCT Pub. No. WO91/13574 PCT Pub. Date Sep. 19, 1991.A sofa or armchair with adjustable sitting depth (7-8), which has a back rest (1), which can be detached and taken off and the distance of which can be changed and thus, the sitting depth can be changed, and to which belongs an adjusting and locking device (2), with which a stepless or adjustment with steps are locked. E.g. the back of a sofa is traditionally fixed and almost all adjustment possibilities have been different solutions by cushions, which however, are not always satisfying when thinking of needs of different people. With this solution people of different lengths can adjust the sitting depth of a sofa or armchair fitting to themselves, which at the same time makes the sitting more comfortable and along with that reduces likelihood of back problems. Also the adjustable back rest gives new dimensions and possibilities for furniture design and product development.

Abstract: PCT No. PCT/FI82/00050 Sec. 371 Date Jun. 27, 1983 Sec. 102(e) Date Jun. 27, 1983 PCT Filed Oct. 27, 1982 PCT Pub. No. WO83/01679 PCT Pub. Date May 11, 1983.The invention concerns an automatic, mass-obturated hand firearm comprising a body (1) with handle (2), a barrel (3) joined to the body, a breech block (4) with guide (5) constituted by the body and with cocking and firing mechanism (7), the guide of the breech block ascending rearward so that the rearward path of motion of the breech block deviates upward from the center-line (8) of the barrel. The purpose is to eliminate the problem of automatic hand firearms that during shooting the barrel tends to rise upwards. As taught by the invention, when the breech block (4) is in its forward position its center of gravity (9) is located forward of the handle (2). The breech block (4) is preferably disposed to have its major part forward of the rear end (10) of the barrel (3). Furthermore, the center of gravity (9) of the breech block (4) is preferably located forward of the rear end (10) of the barrel (3). The guide (5) of the breech block (4) forms a preferably obliquely forward and downward inclined surface, against which the breech block rests so that when the rearward directed recoil force acts on the breech block this plug moves rearward and the surface of the breech block hits against the surface of the guide, producing on the body (1) a moment turning downward the muzzle of the barrel (3).

Title: Method and apparatus for conducting electrochemiluminescent measurements
Inventor: HALL LEE O
IPC: H03K4/02
Filed: 1990-03-16
Granted: 1994-06-28
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for triggering and measuring electrochemiluminescent phenomena using a voltage waveform applied at the voltammetric working electrode which improves the precision and accuracy of measurements.  This waveform has a decreasing scan rate in the range of voltages for which electro-chemiluminescence is triggered and is substantially sinusoidal in shape in this range. The waveform results from locating the reference electrode of a potentiostat in close potential proximity to its counter electrode, and applying a uniform scanning voltage waveform at the reference electrode.  The waveform also can be synthesized digitally, converted to analog form, and applied directly to the working electrode with the reference electrode in close potential proximity to the working electrode.

Title: Rack and pinion lifter
Inventor: COTTER PATRICK J
IPC: F16H19/00
Filed: 1990-05-17
Granted: 1995-04-11
Abstract: A device with one or more actuator racks carried by a housing for reciprocation and each meshing with a separate pinion gear having a non-circular central hole in which a complimentary coupling shaft can be removably received for rotation in unison with the gear(s).   The pinion gears are carried and journalled for rotation in the housing by a pair of co-axial bushings with generally opposed and spaced apart axially projecting rims received in mating peripheral shoulders in the side faces of the gears. The gear teeth extend generally axially continuously between their side faces with the shoulders in their side edges.  Preferably the radial extent of each shoulder is less than the radial extent of the teeth.  When the coupling shaft  is  removed  from  the  gears  each  pinion  can  rotate independently of the shaft and each other to initially position its associated rack at a desired location and when the shaft is  inserted in the pinion gears  they rotate  in unison to simultaneously actuate the rack(s).

Patent CA-2040575-C (CA)
Inventor: THOMPSON PETER
IPC: F16J15/40
Filed: 1991-04-16
Granted: 1996-11-26
Abstract: An arrangement for applying a back pressure to a shaft seal of a mechanism such as a pump comprises a piston slidable in a cylinder one end of which communicates with the fluid being pumped and the other end of which contains oil communicating with a sealed chamber on that side of the seal remote from the fluid. Hitherto, the piston has created a preponderance of the back pressure over the pressure of the fluid by virtue of its weight. This preponderance has been very small, and the rolling diaphragm seal needed on the piston has been easily ruptured if the oil has been lost, thereby allowing possibly hazardous fluids to escape. A greater preponderance of the back pressure, allowing the use of a stronger type of piston seal, is provided by urging the piston towards the other end of the cylinder by a spring as well as by the pressure of the fluid. A magnet on the piston remotely actuates a series of flaps hinged along the exterior of the cylinder to give a visual indication of the position of the piston and also effects automatic replenishingof the oil if necessary or operates a remote warning signal when replenishing is needed.

Title: Sprinkler head
Inventor: GRASSBERGER ROLAND
IPC: B05B15/02
Filed: 1991-02-20
Granted: 1999-09-28
Abstract: In a sprinkler head comprising a sprinkler body (1) and a sprinkler base (4), the nozzle wall of the sprinkler base (4) is the fixed supporting plate (8) of a rubber-elastic nozzle plate (11) resting on it. The nozzle plate (11) comprises a plurality of elastic nozzle projections (12) formed on it which engage in receiving bore holes (9) of the supporting plate (8). The axial length of the elastic nozzle projections (12) in relation to that of the receiving bore holes (9) is such that their elastically deformable ends always project beyond the outer surface (14) of the supporting plate (8). Furring of the nozzle projections can easily be removed by exerting a slight external force on the elastically deformable ends. Nevertheless, the spray-forming outlet ends of the nuzzle projections (12) are so thick-walled and of such material quality that they withstand ordinary water pressures and therefore have good spray guidance properties.

Abstract: A formulation for a resilient gasket coating which is curable by ultraviolet radiation without emitting fumes into the surrounding environment. Different portions of the coating are cured by successive exposure to two different wavelengths of ultraviolet radiation during a continuous in-line process. The first wavelength cures an inner portion of the coating and bonds the coating to the substrate. The second wavelength cures a coating surface.      The formulation permits ultraviolet curing of thicker pigmented coatings than have been previously known.
