Title: Fluid flow Transducer
IPC: G01F1/36
Filed: 1979-10-24
Abstract: A transducer for measuring and monitoring fluid flow in a fluid circuit comprises a strain gauge sensor having an element located in the fluid circuit to monitor the fluid flow through the circuit, the element being such that impingement of the fluid flow produces a stress which results in changes of the electrical resistance of the element, said sensor being connected to one arm of a Wheatstone bridge in an electronic circuit. An unbalanced output signal from the bridge circuit provides a signal proportional to the fluid flow rate or flow rate changes and may be used to actuate a fluid flow metering device. An annulus may be used for flow constriction.

Title: Improvements in or relating to surface covering
IPC: D06N1/00
Filed: 1954-01-10
Abstract: 795,176. Surface covering compositions. ARMSTRONG CORK CO. Jan. 10, 1956 [April 18, 1955], No. 807/56. Class 140. A method for producing a surface covering in which stove-staining is substantially eliminated, comprises the steps of applying a siccative oil-resin composition to a felt-supporting layer containing proteinaceous material which has been pretreated with a tanning agent, and curing said composition at elevated temperatures. The tanning agents specified are aldehydes (including aldoses), e.g. formaldehyde, paraformaldehyde, glyoxal and dextrose; tanning metal salts, e.g. aluminium sulphate, chrome alum, calcium sulphate and nickel sulphate; polybasic organic acids, e.g. oxalic, citric, succinic, maleic or phthalic acids; polysulphonic acids, e.g. sulphonate polystyrene ; natural tannins; syntans and ketones and ketoses, e.g. fructose, acetone and dihydroxy acetone. The siccative oil-resin composition may comprise drying oils, semidrying oils or tall oil esters with rosin, copals kauri gum, congo gum, urea-formaldehyde resin, phenol-formaldehyde rosin or petroleum residues. The water-soluble tanning agents may be applied in aqueous solution to the proteinaceous material either before or after the felt is formed, and those that are insoluble in water may be applied in a suspension or slurry. According to the tanning efficiency of the tanning agents varying amounts of tanning agents are applied to the proteinaceous material but the preferred amount is that equal by weight to the weight of the proteinaceous material present in the felt. It is stated in the Specification that the tanning reaction need not take place prior to the curing operation, since as long as the tanning agent is present the reaction will proceed at the elevated temperatures used for curing the siccative oilresin composition.

Title: Method and apparatus for welding
Inventor: ARTZER RICHARD F
IPC: E04C5/06
Filed: 1982-05-18
Abstract: A three-dimensional composite structural panel of a number of parallel trusses mutually spaced by interposed insulative elements and interconnected by cross wires, is fabricated by positioning a cross wire transversely of the longitudinal runner wires of trusses after they are stacked in alternation with the insulative elements, and then welding the cross wire to the runner wires at each point of contact. Rows of electrodes, one for each side of the lattice, are mounted to simultaneously resistance weld a single cross wire at each side of the lattice to all of the trusses of a panel. All of the electrodes are pressed against the wires to be welded by means of individual fluid motors energized with a common fluid pressure and separately driving individual electrodes. A plurality of backup fingers, normally positioned out of the path of motion of the stack of trusses and filler elements as the stack moves past the rows of opposed electrodes, are shiftable to a weld position in the path of extension of the runner wires and cross wires as they are pressed by the electrodes during the welding. <IMAGE>
