Abstract: ADJUSTABLE DC PULSE CIRCUIT FOR VARIATION OVER A PREDETERMINED RANGE USING TWO TIMER NETWORKS                ABSTRACT OF THE DISCLOSURE    A circuit for providing a dc pulse, such as to a gated semiconductor for at least partial bypass of a ballast element connected to an HID lamp, the pulse being developed within a time range of an associated ac voltage.  A first timer operably connected to the ac voltage produces a first dc output pulse and a second timer connected to the output of the first timer produces the circuit dc pulse output.          Reduction of a threshold control voltage of the first timer permits a time constant network connected thereto to advance the conclusion of the output of the first timer forward within its operational range.  A time constant network connected to the second timer has charge current added to it from the first timer control voltage, the amount of such current decreasing with an advance positioning of the output of the first timer, thereby increasing the slope of the charge-up voltage of the second time constant network and shortening of the related square wave or dc pulse output from the second timer.

Abstract: 10.2.1979                 1                    PHN 9215 ABSTRACT     By deflecting the electron beams before the focusing lenses in an electron gun system for a colour display tube towards the tube axis by non-symmetrical lens fields so that they converge on the display screen, it has proved possible to obtain symmetrical focusing lens fields by means of mechanically non-symmetrical elec-trodes the axes of which are parallel, if the beams en-close a given angle with the gun axes. This enables an easy manufacture of the electrodes and an accurate assem-bly of the guns. In these guns the focusing of the beams is independent of the convergence.

Abstract: MOMENTUMLESS SHUTDOWN OF A      JET DROP RECORDER              ABSTRACT OF THE DISCLOSURE A method and apparatus for terminating the flow of liquid coating material from a jet drop recording device without splattering or seepage is provided.  A supply of coating material under pressure is pumped through an inlet valve to a mani-fold in the printing head of the device.  Shutdown is initiated by closing the inlet valve, terminating the supply of coating material.  When the pressure in the manifold has dropped to the minimum required for normal operation of the recording device, an outlet valve connecting the manifold to a source of vacuum is opened, rapidly reducing the pressure in the manifold to atmospheric and terminating the flow of coating material from the printing head.  A control unit is provided to open and close the valves and monitor the pressure inside the manifold to insure proper sequencing during the shutdown procedure.

Abstract: An evacuated, double wall, tubular solar energy collector having a concave, specular reflecting surface corresponding to a segment of a cylinder positioned at the opposite side of the collector tube from the sun. The reflector is detachably connected to the tube and the tube is engaged by raised spacing points on the reflector to provide the proper spaced relation between them and allow for water drainage along the reflector. Plural units of the collector tube and cylindricallyshaped reflector combination are supported along opposite sides of an elongated manifold for circulation of an energy absorbing media through them.  This system improves the efficiency of total energy collection without tracking the sun or focusing the reflected radiation.  The tubes are no more than three diameters apart and the cylindrical reflector has its focal line within the absorbing area of the collector tube.  The radius of curvature of the reflector surface exceeds the radius of the tube and is defined as a function of the tube diameter and tube spacing.

Abstract: ABSTRACT OF THE DISCLOSURE           A short pulse radar drill guidance system for mapping coal or other mineral seam dimensions.  The system comprises a casing, a source of electromagnetic pulses mounted within the casing and a transmitting means mounted within the casing and connected to the source of electromagnetic pulses to transmit the pulses into the earth.  A receiving means is mounted within the casing and spaced relationship to the transmitting means to receive electromagnetic energy which returns to the receiving means following the reflection of the electromagnetic pulses from various geological discontinuities within the earth.  Directive antenna means are provided for the transmitting and receiving means and mounted within the casing.  A control circuit means is mounted within the casing for controlling both the transmission of the electromagnetic pulses from the transmitting means and the reception of the electromagnetic energy by the receiving means.  The control circuit is connected to both the transmitting means and receiving means in spaced relationship to the former such that the transmitting means is positioned intermediate the control circuit means and the receiving means to prevent electromagnetic coupling.  The drill guidance system according to the present invention provides a new and improved means for mapping the boundaries of a mineral seam through the use of radar technology, and permits circuitry which is sufficiently reduced in size to fit within a bore hole tool for insertion into standard sized bore holes, with the control and transmitting/receiving functions being performed at the down hole location of the bore hole tool.
