Abstract: This invention aims at providing a woven fabric having a structure suitable for bonding, so as to bond a so-called "tarpaulin sheet", which is bonded by sewing means and is obtained by coating a synthetic resin to a fiber base fabric, to a woven fabric such as a tape or a belt. The present invention further aims at providing a woven fabric having a structural portion enabling a woven fabric to be bonded to another woven fabric. A woven fabric 100 is divided in a longitudinal direction or in a transverse direction, or in both the longitudinal direction and the transverse direction, and either one, or both, of warps and wefts are woven more coarsely in at least one of the divided zones 22, 32 than the rest so as to form a mesh portion 2.

Abstract: A plastic reusable container that can be collapsed into a small package for storage.

Abstract: A wall mounted power supply for a remote instrument handle has a novel self compensating voltage regulating circuit that remains in precise calibration despite variable voltage drops in the load, cabling, and control switches. Power output is enabled by an infrared emitter-detector combination disposed in the device's cradle that senses the absence of the instrument handle therein.

Abstract: A linear control valve that includes a flexible cantilevered beam having a seal mounted thereon that is arranged to open and close against a fluid port as the beam is flexed. The free end of the beam is in contact with a motor driven deflector and the amount of flexure controlled by selectively positioning the motor.

Abstract: Alkoxynaphthalenecarboxylic acid is produced by a process comprising the addition of 1,3-butadiene to alkoxyalkylbenzene to yield an adduct. The adduct is cyclized in the presence of an acid catalyst to alkoxyalkyltetralin. The tetralin derivative is then dehydrogenated to produce aloxyalkylnaphthalene, which is oxidized to alkoxynaphthalenecarboxylic acid.

Abstract: A wire rope vibration isolator includes a coil of wire rope having a predetermined number of individual consecutive coils, a first crimp bar, and a second crimp bar. Each of the crimp bars is essentially rectangular in shape and has a pair of opposing side surfaces. A series of lateral holes extending from one side surface to the other side surface of each of the bars is provided so that the predetermined number of individual consecutive coils may be threaded through the series of lateral holes of each of the bars. A crimping force is applied to each of the two crimp bars at a point where each of the individual coils passes through a respective bar. The coils are thereby secured in a fixed position relative to one another while remaining elastically deformable. A spring-like quality is thus imparted to the coil of wire rope so that the first crimp bar and the second crimp bar may move relative to each other to dissipate vibrational energy.

Abstract: A warmer and dryer for fabric articles having a vertically disposed heated frame upon which one or more articles can be draped. A heated fluid is circulated through the frame by a pump that is mounted in the base of the frame. The frame is enclosed by a flexible enclosure made from a material that retains heat while at the same time allowing moisture to pass therethrough into the surrounding ambient. Sufficient heat is provided to warm the atmosphere within the enclosure.

Abstract: This plate heat exchanger with parallel and counterflow circulation of the heat-exchange fluids is constructed by stacking a determined number of ribbed plates (4) of the same size, clamped against one another between two flanges (1,2), said plates having openings (5,6,7,8) in their corners, defining, within the stack, supply and outlet channels respectively for the heat-exchange fluids.The plates are made of bulk machined graphite, previously impregnated with a waterproofing material, and in particular a resin.

Abstract: A treatment system for aerating, cooling and heating or draining a site such as a golf course green or a playing field. A mobile blower can be connected and disconnected with an underground duct network situated under the site through a suitable valving arrangement so that one blower can be used in servicing a number of sites.

Abstract: An electronic circuit for measuring current in a working circuit is provided with a first operational amplifier having a positive input, a negative input, and an output connected to at least one in-line amplifier to form a first current path. A second operational amplifier having a positive input, a negative input, and an output connected to a differential amplifier is provided within the circuit to form a second current path. An input terminal is connected to the negative inputs of each of the operational amplifiers to provide a connection between the electronic circuit and the working circuit. A variable conductance component is connected in series between the input terminal and the negative input of the second operational amplifier to control the flow of variable currents through the two current paths.

Abstract: A leak indicator for detecting leaks in a vacuum system including a chamber and a system vacuum pump. The indicator is provided with a mass spectrometer for identifying the presence of a test gas in the system chamber and a high vacuum pump for producing the pressure required for operation of the mass spectrometer during a system leak test. A sealed conduit network is provided to connect the system chamber to the inlet of the mass spectrometer, and to the inlet side and exhaust side of the high vacuum pump. A first switching valve is provided within the sealed conduit in series between the system chamber and the inlets of the mass spectrometer and the high vacuum pump. Lastly, a constriction member is connected within the network conduit in series between the system chamber and the first switching valve to selectively provide a direct connection between the system chamber and the inlet side of the high vacuum pump, or between the system chamber and the exhaust side of the high vacuum pump.

Abstract: A one piece electrode for use in miniature and subminiature lamps having a large diameter post section and a smaller diameter lead-in section. The lead-in section is formed by an electrochemical process from a wire that has an outer diameter equal to the desired post diameter. A smooth evenly tapered transition section between the post and lead-in sections is created during the etching process which permits heat to pass through the electrode at a controlled and predictable rate.

Abstract: This generator for supplying high-frequency power to an arc lamp (12), coises:a primary circuit (1) connected up to the terminals (5, 6) of the power-supply mains and incorporating an electromagnetic inductor (L', T) connected to a resonant circuit (7);a secondary circuit (2) comprising, in series, the arc lamp (12) and an electromagnetic sensor (E.sub.1, E.sub.2) making it possible to provide magnetic coupling with the primary circuit (1) at high frequency.The secondary circuit (2) is formed by two electrical circuits (10, 11) mounted in parallel with the terminals of the lamp (12), each of the two circuits incorporating an electromagnetic sensor coupled with the electromagnetic inductor of the primary circuit (1).

Abstract: A reusable surgical device which is suitable for carrying elongated surgical instruments having a backing plate which supports a plurality of detachable receptacle members contained on the backing plate in fixed engagement.

Abstract: An apparatus for making a bubble spring assembly includes a base member having a side surface and a head assembly. A track way extends along one side surface of the base toward the head assembly. The track way is employed for guiding a respective spring blank into the head assembly. A push block is provided for moving the spring blank along the track way and into the head assembly. A shaping mechanism is provided within the head assembly for receiving the respective spring blank from the track way and for shaping the spring into a predetermined form having a predictable stress strain history along the length of the shaped spring blank. A retaining gate is located proximate the shaping mechanism for positioning a respective cavity block adjacent the shaping mechanism. A transfer rod is provided within the head assembly for moving a shaped spring blank from the shaping mechanism into the cavity block in the absence of further deformation to the shaped spring blank.
