Abstract: A joint member (1) is substantially elongated and has a stabilizing parts (2, 3) which retain the joint member in a desired orientation in use. Seal members (6, 7) are provided on the joint member and engage sides of an aperture into which the joint member (1) is positioned. The joint member includes an insertion part (5, 8), or divider plate, which enables the seal members (6, 7) to be placed in a desired position in use. The method of providing a nosing on edge faces of cementitious members includes positioning the divider plate (5) between the edge faces and inserting settable material (14, 15) between the elongated divider plate (5, 8) and the edge faces, then allowing the settable material to set.

Abstract: The portable sewing kit includes an elongated housing for holding a needle with a point at one end and an eyelet at the other end.

The spool section has a width which is smallest at the end connected to the housing and increases to reach a maximum at the end furthest from the housing. A button is integrally connected to the spool section and is coplanar with both the spool section and the housing. The button has a diameter which is substantially equal to the maximum width of the spool section.

This composition is useful in electronic packaging for forming conductor patterns on ceramic-based substrates, particularly patterns on which metallic components are bonded by brazing.

Abstract: A method and apparatus for capturing digital radiographic images. More particularly, the present invention relates to a method and associated apparatus for reading varying electrical charges representing a latent radiographic image stored in a unique microcapacitor matrix structure to obtain an electrical signal representing a radiogram. The microcapacitor matrix structure or element comprises a first, electrically conductive, backing layer, a second photoconductive layer, a third dielectric layer and a plurality of conductive microplates having dimensions coextensive with a minimum resolvable picture element.

Abstract: A catheter attachment device comprises a first pad of medical grade adhesive having one surface covered by a removable protective layer, a second surface covered by a plastics film, and, attached to the film, a second pad of medical grade adhesive. A surface of this second pad which faces away from the first pad is covered by a removable protective layer and has a plastics film on its other surface. The two plastics films are attached to each other over a central region substantially smaller in area than the areas of both the first and second pads.

Abstract: A broadband phase shifter and vector modulator includes two artificial transmission lines interconnected by FETs to selectively produce and sum incremental phase shifts of an input signal. A number of low pass filter sections are connected in series to form the first of the two artificial transmission lines and a number of high pass filter sections are connected in series to form the second artificial transmission line. Use of low pass and high pass filters equalizes transit times of each phasor through the phase shifter so as to maintain the proper phase relationship between the phasors over a broad bandwidth. Each of the two artificial transmission lines are coupled to a transistor circuit connecting corresponding low and high pass filter sections. The phase shifter operates by selectively summing the output variable-amplitude phase-shifted signals generated within the transmission lines to produce an output signal having a phase shift between 0.degree. and 360.degree..

Abstract: This invention relates to organic optical waveguide devices which have improved barrier properties after having been coated with silicon monoxide, and then with silicon dioxide doped with certain metals.

Abstract: An annular mounting member is bonded to the pouch wall to define a vent opening. The mounting member is made of material which is compatible with the pouch film and has a smooth exterior surface adapted to facilitate removable mounting of an adhesive coated element in alignment with the opening. The element may be a deodorizing filter assembly including a filter disk surrounded by an annular border member coated with pressure sensitive adhesive or a gas impermeable cover member designed to close the vent.

Abstract: A checkout counter for supermarkets and the like incorporates therewithin dual bag feeding apparatus, each operable for automatically dispensing, delivering, opening and retaining a flexible bag in a position and location suitable for the convenient introduction of purchased articles into the bags. The checkout counter includes two continuous web reels of successively attached flexible bags, two hoppers below each of which an open bag is retained and through each of which purchased articles are selectively insertable into the underlying bag as the articles are checked by the cashier-operator, and two collecting stations into which filled bags are ejected from the checkout counter interior and from which the customer may retrieve the filled bags.

Abstract: A replacement single tiller (1) has a cubical hollow base (4) from which throttle-operating cables (8a 8b) (etc) extend to different motor throttles for simultaneous throttle control. Within base (4) is rotary shaft (33) mounting pinions (30, 31) about the peripheries of which cables (8a 8b) are respectively moved by push-pull entrainment. Twist grip (3) on shaft (33) therefore controls both motors. Projection (5) fits between parallel arms of a motor bracket and is held therein by pin (18) in bore (14); such brackets are mutually interconnected by a transverse conducting rod for joint steering by the tiller.

Abstract: The invention pertains generally to ultrasonic imaging systems and is more particularly directed to use of such systems for nondestructive testing to measure the thickness of parts, or to examine parts suspected of having internal flaws but where access is often limited to the external surfaces. The invention makes thickness and flaw determinations of substantial accuracy without resulting to use of an expensive ultra high frequency clock to measure time.

The laser is focused about 0.2 to 0.3 mm above the work piece. The predominantly single mode is a TEMoo mode. By recutting the capillary slots with the laser, metal oxide particles condensed from the vapor phase and resolidified molten metal on the walls of the slots are removed.
