Abstract: GHOST CURSOR IN DISPLAY ALL CODES MODE                           Abstract A ghost cursor indicates the relative horizontal position on a display screen associated with a printed document rendition of the displayed text and control codes.  In a normal, or hidden codes, mode of operation the ghost cursor, placed on an escapement scale line, is vertically aligned with a text cursor which is posi-tioned adjacent the displayed text code which defines the present point of operation.  In the all codes mode, all text and control codes (such as required back-spaces, tabs, etc.) are displayed.  In the all codes mode the ghost cursor indicates the relative horizontal position on the display screen of the code associated with the text cursor, with forward or reverse escape-ment indicated by the control codes taken into account.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus for automatically energizing and de-energizing a parking light responds to both the ambient brightness and the brightness of incident light from a sources, e.g. headlamps, moving relative thereto.  The signal produced by an optical sensor is utilized in a com-parator circuit for comparing the ambient brightness with a predetermined brightness threshold and is additionally supplied to another comparator circuit which determines occurring dark-bright transitions.  The latter comparator circuit will energize the light only if the actual ambient brightness does not exceed the predetermined brightness threshold.

Abstract: ABSTRACT OF THE DISCLOSURE     PRODUCTION OF A DAIRY EMULSION     A method of making cream involves separating high and low melting point fractions from butter oil, and emulsifying one of the fractions with a low fat milk fraction enriched in membrane substances.  Emulsification of the high melting point fraction can give whipping creams of low fat content and temperature sensitivity and good viscosity, especially if the cream is homogenised, pasteurised and then homogen-ised again and if the cooled cream is tempered by warming and recooling.  Emulsification of the low melting fat fraction yields cream churnable to butter which spreads at refrigerator temperatures.          The low fat milk fraction may be the serum separated in the production of the butter oil, but there may be used instead or in addition butter-milk or butter serum from another source.  The butter fat fraction may be emulsified together with a non-milk fat.

Abstract: VENEER LATHE DRIVE WITH POWERED ROLLS                     Abstract of Disclosure A veneer lathe apparatus is described including three powered drive rolls between which a log is clamped for rotation about a lathe axis while the log is engaged by the lathe knife for peeling a sheet of veneer therefrom.  One of the powered rolls is employed as a reference roll for the other two rolls, such reference roll being held by a reference means locked in a reference position during peeling.  The reference position of the reference roll is automatically adjusted relative to the lathe axis and to the other two drive rolls in response to changes in position of the lathe knife during peeling to maintain such reference roll in contact with the log.  The other two drive rolls are driven by a common drive motor and supported on common support arms for movement toward and away from the reference roll while maintainng the spacing between such other two drive rolls substantially constant.  The reference means includes a cam member for determining the horizontal path of the reference roll and for locking the reference roll in a vertical reference position during peeling.  An automatic adjustment means including a motor driven lead screw is employed for pivoting the cam member vertically in response to changes in the position of the lathe knife during peeling to adjust the vertical reference position.  The other two powered rolls are mounted on common support arms which pivot about an eccentric that is rotated by an eccentric motor to different rotational positions in response to changes in position of the knife to adjust the position of the pivot axis of such support arms in order to maintain such two drive rolls in contact with the log during peeling.

Abstract: ABSTRACT           A two-cycle, gas-powered engine which is capable of operating over a wide range of loads including those (e.g. idle speed) which have previously caused misfirings in known engines of this type.  A specially constructed head and piston assembly and a governor-controlled fuel system are incorporated into an otherwise typical two-cycle engine to convert the  engine into a stratified charge engine.  The head and piston assembly is constructed to provide an ovate-domed, flat-bottomed combustion chamber therebetween when the piston is in a top dead center position in the cylinder.  This combustion chamber allows fuel injected in the top of the combustion chamber to mix with air being compressed by the piston to provide a rich stratified charge around the ignition means (e.g. spark plugs) which are also positioned near the top of the chamber.  This charge is always rich enough to support rapid ignition and to quickly spread burning to the weaker, exhaust-contaminated mixture present in the lower combustion chamber.  Further, a squish area is defined by tapered surfaces on the head and on the piston which has the effect of reducing or breaking the swirl of the weaker mixture in the lower combustion chamber while increasing the swirl (i.e. turbulence) of the stratified charge in the upper section, thereby aiding in maintaining the stratified charge in the uppermost portion of the chamber to insure ignition.

Abstract: ABSTRACT OF THE DISCLOSURE           Ultraviolet radiation is the wavelength range between 150 and 300 nanometers, which both generates ozone (O3) and has a germicidal effect both in ambient air and in a pure oxygen atmosphere, is performed in a highly energy-efficient manner, by utilizing a low-voltage, low-pressure gas discharge lamp, by using a radiation-transparent quartz tube, by equipping it with a long-lasting sintered electrode pair and filling it with a mixture of gas vapor and mercury vapor, by disposing a circuit device between the mains and the gas discharge tube which rectifies the mains alternating current and effects smoothing voltage multiplication, and by coupling this circuit device with an automatic, dry-switching commutator device for the direct current of the gas discharge lamp, in order in principle to avoid a mercury-vapor dissociation (cata-phoresis) which would reduce the effectiveness of the radiation.  As a result of the direct current operation, the energy efficiency of the W radiation generator is improved by up to 30%, as compared with direct operation of the gas discharge lamp with alternating current and a standard alternating current choke, because of the reduction in heat losses both in the gas discharge process and in the voltage multiplier choke.
