Title: Knife gate valve with semi-hard, resilient seat
Inventor: KING NOLAN D
IPC: F16K3/02
Filed: 1986-10-21
Granted: 1991-07-23
Abstract: KNIFE GATE VALVE WITH SEMI-HARD, RESILIENT SEAT            Abstract of the Disclosure A knife gate valve comprises a body member to which two aligned conduits are attached.  The body member has a U-shaped internal recess of predetermined length formed within it.  A removable sealing member fits within the recess and extends along its entire length.  The sealing member includes a bearing portion and a resilient backing portion that are positioned face-to-face to each other.  The bearing portion comprises a flexible plastic-type material having a self-lubricating, semi-hard surface that contacts the blade portion of the gate as it slides along the length of the recess to close the valve.  The resilient backing member com-prises an elastomer strip that contacts the bearing portion surface that is opposite to the blade portion contacting sur-face.  The resilient backing portion yields to the pressure exerted by the gate as it closes, thereby to provide a tight seal for the valve.

Abstract: An angle modulator operated intermittently and used with a frequency modulation type of a phase modulated type radio equipment, and others. A frequency control voltage and an input modulating signal are applied to individual terminals of a variable capacitance diode, so that a period of time necessary for the frequency control voltage to reach the variable capacitance diode may be shortened without being effected by a coupling capacitor which is adapted for the modulating signal and provided with great capacitance. This allows the center frequency of an output signal of the modulator to be rapidly tuned to a prescribed one after the start-up of the modulator.

Granted: 1992-07-14
Abstract: ABSTRACT OF THE DISCLOSURE   An extruder die head for extruding profiles, particularly plastic pipes.  The die head includes an inner mandrel and an outer sleeve, between which is defined a flow channel.          Adjacent the outlet of the die head, the flow channel defines an outlet flow zone that tapers inwardly toward the axis of the die head to define a converging flow passage, and at a point upstream of the outlet flow zone the flow passage diverges outwardly in the direction of material flow, to provide a pressure balance zone whereby the axial pressures acting on the outer sleeve are in opposite directions to substantially offset each other.  The outer sleeve is axially movable relative to the mandrel by means of an external thread that engages with a rotatable adjusting sleeve that is driven through a gear train by a drive motor.  The outer sleeve is restrained from rotation relative to the mandrel, and is movable only in an axial direction relative thereto.  The outlet flow zone is defined by a pair of opposed curved surfaces that are preferably circular arcs and that flare inwardly toward the die head axis so that the material that passes through the outlet flow zone flows in a direction generally tangential to the axis of the die head to provide a smooth, substantially tangential flow path at the die head outlet.

The  surround  sections  included  channels  to receive  panel  material  and  leg  portions  with  opposed grooves  to  releasably  engage with a clip rail  section. The clip rail  section enables various panel structures, such as corner posts, to be interconnected with the panel members.   The  clip rail section has a tongue extending generally  in  the  direction  perpendicular  to  the  panel member and so shaped as to be resiliently engageable with a tongue of an adjacent clip rail section whereby panel members or other panel structures can be clipped together along their length by relative transverse movement.  The clip  rail  section  includes  opposed,  outwardly  extending flanges and perpendicular leg parts which cooperate with the  channels  of  the  surround  section  to form a  recess having  a  narrow  mouth.   A  workstation  support  bracket is retained behind a nib in the recess and wedges therein to lock the bracket relative to the panel members.

Granted: 1992-03-31
Abstract: ABSTRACT (ref. Fig 1) BIDIRECTIONAL OPTICAL SPACE SWITCH     A bidirectional optical space switch for selectively coupling an input signal to a selected output comprises two arrays of inputs (19 8), two arrays of outputs (5, 9), polarising beam splitters (2, 4), and a matrix of cells (3) each of which is selectively capable of varying the polarisation state of light passing through it in response to an applied control signal.  A first optical system (5) couples each of inputs (1) and a corresponding one of outputs (9) with a corresponding column of cells while a second optical system (7) couples each of inputs (8) and a corresponding one of outputs (5) with a corresponding row of cells.  One of inputs (1) is switched to one of outputs (5) by activating the appropriate cell so that it rotates the polarisation of light passing through it by 90°. This also couples one of inputs 8 to one of outputs (9) thereby providing bidirectional switching.  Use of combined beam splitters and polarisers (2, 4) provides bidirectionalily at substantially  no loss of light additional to that lost on discrimination of the polarisation states.

Abstract: METHOD OF DIFFUSING ESSENTIAL  OILS AND OLEO-RESINS OF SPICES IN A CARRIER SOLUTION.               ABSTRACT  OF  THE  DISCLOSURE.    This method of diffusing essential oils and oleo-resins of spices in a carrier solution is applicable notably for pre-paring seasonings in the pork product industry. The essent-ial oils are obtained by distilling the spices, and the oleo-resins are the evaporation residues of the dissolution of spices in a solvent. According to the desired concen-tration of the diffusion contemplated, the essential oils and the oleo-resins are reduced by the action of a high pressure followed by a sudden expansion. The presence of an emulsifier in the mixture prevents the microparticles from reforming a mass. The homogeneity of the mixture is obtained by forming an emulsion by stirring. The invention is applic-able more particularly to the food industry in general.

Abstract: ULTRASOUND IMAGING SYSTEM FOR RELATIVELY LOW-VELOCITY           BLOOD FLOW AT RELATIVELY HIGH FRAME RATES                    Abstract of the Disclosure An ultrasound blood flow imaging system employing a moving-target-type Doppler processor having a passband extend-ing from zero hertz to the repetition frequency of the pulses generated and processed during each beam.   The system is able to image low-velocity blood flow by reducing the frequency at which  pulses  are  generated  and  processed  during  each  beam, thereby  increasing  the  gain  of  the  flow  processor  at  low frequencies.  In order to avoid a corresponding decrease in the frame rate,  the ultrasound pulses for several beams are alter-nately generated and processed in interleaved sequence rather than generating and processing all of the ultrasound pulses for each beam before generating and processing  ultrasound  pulses for the next beam.
