Abstract: Abstract of the Disclosure A needle valve comprises a valve body including a conduit portion through which a flow passage is formed and a bonnet portion which screws into a cylindrical well formed in one side of the conduit portion to inter-sect the flow passage and form a valve chamber within the valve body.  The bonnet portion is bored through to support a valve stem upon which is mounted a frusto-conical member, the valve stem and the bore through the bonnet portion being threaded for movement of the frusto-conical member transversly across the flow passage via turning the valve stem.  A tubular liner, formed of a flexible material, extends around the peri-phery of the valve chamber and  is split into two semi-cylindrical sections which receive the frusto-conical member and are spread thereby against portions of the valve chamber wall pierced by the flow passage as the frusto-conical member is seated in the liner.  Tabs are formed on the bottoms of the liner to extend into a slot formed in the bottom of the valve chamber to prevent rotation of the liner without interfering with the spreading of the liner to seal the valve against flow through the flow passage.

Abstract: Abstract of the Disclosure The present invention relates to a method of producing a cold rolled steel sheet for deep drawing.     In order to improve the deep drawability (r-value), ductility (yield strength and elongation E?) and the like of ultra-low carbon aluminum killed steel, the chemical composition (% by weight) of the steel is adjusted such that the steel contains C : ?0. 015%, Mn : ?0.4%,   P : ?0.03%,   sol. A? : 0.005-0.100%, N : ?0.010%, Ti (exclusive of Ti present in the form of oxide) : in  an  amount  satisfying  a  formula  of   the hot rolling of the steel slab is effected at a soaking temperature lower than 1,100°C and at a finishing temperature of 600-780°C.          As illustrated in the drawings,  a low temperature rolling can be carried out, and the resulting cold rolled steel sheet is excellent in the deep drawability and ductility and further excellent in the treatable property of the surface and in the surface property.         Therefore, the cold rolled steel sheet is particularly suitable  for the production of automotive exterior plate.

Abstract: ABSTRACT Apparatus for intermittently dispensing fragile particulate material, such as sesame seeds through openings in a tube to spread material over an array of horizontally and vertically spaced rows and columns such as upper surfaces of buns in a pan.  The dispens-ing apparatus comprises a hopper from which fragile particulate material is dispensed through a dispens-ing tube in which a mandrel driven by a variable speed motor is rotatably disposed.  The mandrel has spaced spline teeth formed on its outer surface in dispensing sections separated by blocking collars spaced longitudinally of the mandrel such that rota-tion of the mandrel causes particulate material to be dispensed in parallel columns and such that inter-mittent rotation of the mandrel causes the columns to be divided to form rows.  The major diameter of the spline teeth on the mandrel is less than the outside diameter of the blocking collars to provide an arcuate annular dispensing passage between the interval of the dispensing tube and the major diameter of the spline teeth in a range of 1-1/2 to 2 times the diameter of particles of material being dispensed.

The arrangement includes electrical circuitry which initially samples the conductivity of a passing resin slurry.  The initial conductivity value is compared to subsequent conductivity values of the passing slurry and the flow of the passing slurry is automatically terminated when the subsequent conductivity value is a certain fraction of the initial conductivity value.  Termination in response to this equality condition effectively detects the interface between classified layers of a mixed resin bed.

Abstract: ABSTRACT:         A frequency multiplying circuit which is partic-ularly suitable for battery operated portable radio equip-ment at VHF, such as radio paging receivers.  The basic frequency multiplying circuit comprises a differential amplifier formed by two transistors (TR1, TR2) whose emitters are connected by a current source (24) to a low voltage supply rail, collector resistors (R1, R2) are con-nected to a higher voltage rail as is also done with the base electrode of one of the transistors, the base elec-trode of the other of the transistors has an oscillator connected thereon.  An LC resonant circuit (L1, C1) coupled between the collectors of the two transistors (TR1, TR2) and is tuned to select either the basic frequency of the oscillator (12) or an odd harmonic thereof.  In order to overcome problems of excessive damping of the resonant cir-cuit (14) due to the collector resistors (R1, R2) of the differential amplifier being effectively in parallel there-with which damping is made worse when the load of the following stage is added, it was found that the frequency multiplying circuit could provide a high quality factor and low power consumption if the coupling between the differ-ential amplifier and the resonant circuit (14) is reduced and also if the effect of the load of the next following stage was overcome.  This is achieved by connecting a nega-tive resistance circuit (22) across the resonant circuit. The negative resistance circuit (22) comprises a transis-torised differential amplifier, the base electrodes of the transistors (TR3, TR4) are cross connected to the collector of the other transistor, to form a negative conductance which is in parallel with the positive conductances which are causing the resonant circuit to be lossy.  Hence the parallel loss conductance is reduced in value and the effective Q is increased.

Abstract: Abstract An injection well used in an in-situ combustion oil recovery process using a high oxygen concentration gas is completed with dual tubing strings to conduct the oxygen-containing gas and nitrogen separately down the well.  The gases are mixed after they leave their separate tubing strings and enter the formation through perforations in the casing.  If the bottomhole temperature of the well increases to a specific level, injection of the oxygen-containing gas is terminated and injection of the nitrogen is increased to a maximum amount until the bottomhole temperature decreases to a desired level for resuming in-situ combustion.  In addition, injection of water into the bottom of the well is available as a back-up in the event that injection of the nitrogen does not lower the bottomhole temperature to the desired level.  The use of the separate tubing strings for nitrogen and oxygen flow permits a faster bottomhole response to be obtained if undesired temperature increases take place downhole.

Abstract: SV-51 COMPACT VACUUM CLEANER A vacuum cleaner is constructed of relatively rigid, molded plastic main structural elements including a direct collecting tank and a motor housing releaseably secured to each other by a buckle. The main structural plastic elements also include a fan housing wherein a centrifugal fan rotates, a mounting plate to which the motor is secured; and a baffle member having a cup formation which receives the rear of the motor. A common fastening means mechanically secures the fan housing, the plate, and the baffle members to the motor housing. A releaseable latch is at one end of the buckle and a hook at the other end thereof. The latch holds the tank and motor housing together, and the hook is for engaging a wall bracket to mount the cleaner in a vertical position. The buckle also includes a skid portion, located between the latch and hook, to facilitate movement of the cleaner along a horizontal supporting surface. Hundreds of relatively small apertures in the mounting plate are arranged in a narrow band adjacent the periphery of the fan so as to provide for the passage of air through the motor mounting plate without creating excessive back pressure while maintaining quiet conditions in spite of high speed air flow.
