Abstract: "IMPETUS AND COUNTERCURRENT ADJUSTABLE SLIDE SEED GRADER  AND PARTICLE SEPARATOR" ABSTRACT OF THE DISCLOSURE      Seed is fed down an adjustable slide and deflect-ed outwardly and forwardly into an airstream.  This allows the heaviest kernels to travel farthest with the lighter kernels falling successively towards the rear.  A plurality of transverse collecting troughs with adjustable baffles, receives the separated grains according to the weight thereof with the top quality grain being heaviest, collect-ing in the forward trough.  A suction fan extracts dust before it reaches the main airstream and diverts it into a cyclone or the like.  Accurate wind control is achieved by a plurality of adjustable wind boards strategically situat-ed within the device.  An even dispersal device receives the grain from the storage facility and ensures even dis-tribution of the various weights of grain, straw, chaff, etc. prior to it being fed to the hopper and hence to the slide thus avoiding the undesirable side separation of the hopper which occurs when a relatively large quantity of grain flows into  and through a hopper.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a process for tertiary recovery of oil from underground deposits of average or high salinity.  A surfactant which is a carboxymethylated oxyethylene compound of formula R-(OCH2CH2)n-OCH2-COOM in which R is an aliphatic or alkyl-aromatic group, n is a number between 3 and 30 and M is an alkali metal, alkaline earth metal or ammonium ion is injected in formation water into the deposit.  The process is characterized in that the phase inversion temperature of a system composed of a crude oil, formation water and the surfactant is between 0 and 10°C higher than the temperature of the deposit and in that the oxyethylene surfactant is not fully carboxymethylated but has a degree of carboxymethylation between 10 and 90%.

Abstract: ABSTRACT OF THE DISCLOSURE          A dual lumen cannula particularly for use in haemodialysis by inserting the cannula into the subclavian or femoral vein of a patient to contemporaneously remove blood from the vein for treatment and to return treated blood to the vein downstream from the point of removal.  The cannula includes a pair of lumens separated by a septum.  Blood is withdrawn through one of the lumens and treated blood is returned through the other lumen.  The cannula is formed from a flexible thermo-plastic material and is sufficiently flexible to permit bending to conform to the shape of the vein without damage or kinking.  The cannula has a peripheral generally cylindrical wall with a septum extending between spaced locations on the interior surface of the wall to define a pair of discrete lumens and at least one of the lumens is deformed by increasing its wall thickness at its end to facilitate insertion.

Abstract: ARITHMETIC MENU FOR INFORMATION PROCESSING SYSTEM                 Abstract of the Disclosure An information processing system (10) includes a terminal (12) with a display screen (16) and a keyboard (18).  The terminal (12) operates in conjunction with a diskette storage (14).  An arithmetic menu is prepared which represents a mathematical function and includes an answer item, at least one operand item and optionally a mathematical operation item.  The arithmetic menu further includes an equation line (40).  When the system operator creates a document which requires a mathematical function the arithmetic menu can be called up from memory.  The operator enters parameter terms for each of the items in the memory.  As the operator enters the parameters for the arithmetic elements, these parameters are displayed on the equation line (40) in an algebraic format. The operator monitors the equation line to insure that the appropriate parameters are being entered and that the correct mathematical function is being utilized. After the parameters are entered into the arithmetic menu the mathematical operation is carried out and the results are incorporated into the document being prepared by the operator.

Abstract: ABSTRACT            A solid state television camera having a solid state image sensing device, such as CCD image sensing device and an iris for control the amount of light from an image irradiated on the image sensing device. The iris is controlled by the peak level of a smear signal of a horizontal scanning line during vertical blanking interval so that the smear signal contained in a video signal from the image sensing decice is reduced. Further, the iris can be controlled by the average level of the smear signal instead of the average level of the video signal of one field as the smear signal has the whole information of the image of one field, that causes the construction of detecting circuit to be very simple and the fidelity of the iris control to be high.

Abstract: Abstract Shot peening of thin edges of workpieces which are subject to deformation damage by direct impacts is ac-complished by rotating the workpiece edge near center-line through a particular angle measured from the nor mal to the shot streamline.  The angle is sufficient to cause oblique blows on the centerline of the edge, but insufficient to cause direct impacts.  Compressive stresses by the oblique blows provide residual com-pressive stresses along the centerline to the desired depth.  The angle is calcuable from the edge radius, the depth of stressing desired at the centerline, and the depth of stressing produced by shot at a reference location.  Oscillatory rotation is preferably used to obtain even peening.

Title: Low-residue brightening compositions and methods for  using them
Inventor: BIRKELO EINAR P
IPC: C11D3/395
Filed: 1982-08-25
Granted: 1985-10-15
Abstract: Abstract The separately-packaged parts of the disclosed, liquid two-part brightening compositions can be combined and then sprayed or otherwise applied onto discolored surfaces (particularly internal walls and ceilings) for the purpose of treating the discoloration and substantially restoring a stain-free appearance. These compositions leave a minimal residue after spraying, which residue is substantially free of titratable chlorine after less than 60 hours at normal ambient temperatures.  The spraying of the composition is generally not complicated by formation of stable foam.  One part of the two-part system comprises an aqueous solution of a hypochlorite salt (e.g. NaOCl) and the other, separately packaged part comprises a nonionic surfactant dissolved in a water-soluble mono-lower alkyl ether of ethylene or diethylene glycol.  Water is a suitable diluent for either or both parts.  The preferred nonionic surfactants have emulsifying and/or detergent and/or surface tension-lowering properties and are ethoxylates, e.g. higher aliphatic alcohols condensed with 3-40 moles of ethylene oxide.  HLB values of these surfactants are preferably below 18, more preferably below 14. The surfactants with the lower HLB values can help to control foam during spraying and help eliminate the need for an additional ingredient specifically for defoaming.  It is preferred to limit these compositions to the fewest possible ingredients, and residue-forming or substantially nonvolatile solids or liquids other than the aforementioned active ingredients are preferably avoided.

Abstract: ABSTRACT OF THE DISCLOSURE         An elevator system including an elevator car and a drive machine having a DC drive motor, a dual converter, and a phase controller for providing gate drive signals for the dual converter.  A reference signal related to the desired motor armature current is developed in response to the  operation  of  the  elevator  system.   The  reference signal  indicates  when  the  current  source  should  be switched from one converter bank to the other converter bank.  The switching is accomplished by a method which includes retarding the  firing angle of the gate drive signals applied to the operative converter, until current is extinguished,  applying the gate drive signals to the other  converter  bank,  and  advancing  the  firing  angle towards  rectification  to  initiate current flow in the on-coming converter.  The rate at which the firing angle is advanced towards rectification is a function of the control signal.

Abstract: Abstract A stabilisation aid for a vehicle- or vessel-borne search unit comprises two servomechanisms for stabilising the observation part (3) of the search unit about two mutually perpendicular axes (S1 and S2) mounted on the part of the search unit which rotates about the search axis (1).

A portion of these input signals are compensating signals for the control errors in the servomechanisms, the principal causes of which control errors being the disturbing torques arising through the non-uniformity in the search motion and the rotational velocity of each of the stators with respect to the rotors of the servomechanism motors on their axes.
