Abstract: Aqueous concentrates of alkali metal salts of  alpha -sulfonated fatty acid alkyl esters (ester sulfonate salts) which are pumpable at temperatures of at least 60 DEG  C. are obtained without the addition of viscosity regulators by preparing pastes containing at least about 60% by weight of ester sulfonate salts derived from C16 and/or C18 fatty acids. More particularly, the concentrates contain less than 10 mole % of ester sulfonate salts with fatty acids containing fewer than 16 carbon atoms. The concentrates are obtained by neutralizing the crude ester sulfonates with concentrated alkali hydroxide solution with intensive cooling at temperatures of at most 90 DEG  C.

Abstract: PCT No. PCT/CH86/00132 Sec. 371 Date May 19, 1987 Sec. 102(e) Date May 19, 1987 PCT Filed Sep. 19, 1986 PCT Pub. No. WO87/01770 PCT Pub. Date Mar. 26, 1987.A device for creating a pressure difference in the flow of a fluid which may be a liquid or a gas and a number of technical applications. The fluid medium is fed along the longitudinal axis of a double cone, consisting of two coaxial hollow cones linked by their smallest faces. At the narrowest point of the double cone a depression occurs in the fluid flow which is made accessible to the outside by means of a lateral connection piece. Compared with a conventional venturi the present double cone offers increased efficiency owing to its special shape, which is defined by geometric parameters. The high efficiency of the double cone, which can be further improved by a special embodiment, makes the device suitable for a number of technical applications.

Title: Valve gating apparatus and method for injection molding
Inventor: SCHAD ROBERT D
IPC: B29C45/28
Filed: 1999-02-15
Granted: 2003-01-09
Abstract: A valve gating apparatus and method for injection molding includes at least one shutter disposed between the gate and the cavity melt channel into a mold cavity. The shutter is moved laterally, between a closed position wherein flow of melt from the nozzle into the cavity is inhibited, and an open position wherein flow of melt into the cavity is unimpeded by the shutter. Intermediate these two positions, the shutter can be employed to reduce the cross-sectional area of the gate to throttle the gate. Embodiments are disclosed wherein one shutter or pairs of shutters are employed to gate the gate. Further, when pairs of shutters are employed, the shutters can abut each other in the close position or can overlie each other. This novel design prevents generation of waste material and eliminates the need to have means for removing cold plugs.

Abstract: IMPROVED SEMI-FLEXIBLE DOUBLE-RIDGE WAVEGUIDE             ABSTRACT OF THE DISCLOSURE      A semi-flexible double-ridge waveguide comprises a corrugated tube formed into a special dumbbell-shaped cross-section defined by parameters which are conveniently optimized to realize improved power-handling capability as well as improved attenuation and VSWR factors across extended dominant-mode operational bandwidths.  The dumbbell-shaped cross-section efficiently removes the problems typically associated with the use of conventional rigid waveguide, including difficulty of installation as well as the need for precise alignment of components, by combining flexibility and ease of manufacture, even for long lengths of waveguide, through use of a continuous, uncomplicated and relatively inexpensive process.    The dumbbell-shaped cross-section is totally devoid of corners and other abrupt protrusions and is defined by a geometric equation in which specific parameters can be correlatively optimized to improve desired electrical properties of the waveguide.  The waveguide is rendered "semi-flexible" by the provision of helical corrugations having a staggered disposition of opposing corrugation crests and troughs, whereby the breakdown air gap and, consequently, the maximum power rating is increased.

Granted: 2001-10-02
Abstract: A system for maintaining a predetermined tension of a wire has a rotatable wire supply spool, a motor-driven wire take-up spool, a motor-drive wire feed spool. The wire is wound around the supply spool and is also attached to the take-up spool. The wire also passes partially around the feed spool and a pulley or guide which is attached to a pivot arm.      The pivot arm is positioned between the take-up spool and the supply spool. A frictional layer is disposed around the outer circumferential surface of the feed spool, to prevent the wire from sliding across the frictional layer of the feed spool.      The elongated pivot arm that has its free end positioned against the wire. The pivot arm pivots in response to the differences in speed between the supply and take-up spool. A motion sensor detects motion of the pivot arm and generates a control signal in response. The control signal is electrically conducted to a stepper motor. The stepper motor is electrically connected in turn to the feed spool to establish the speed of rotation of the feed spool and thereby match the supply spool speed with the take-up spool speed.      The pivot arm can be weighted and oriented at an angle different from its rest position angle to establish the desired tension on the wire.
