Abstract: TILTABLE SUPPORT STAND FOR VEHICLES     Abstract of the Disclosure A low cost, tiltable vehicle support stand is provided which is inherently stable in use and is designed to develop a righting moment during vehicle setup operations so that a vehicle can be quickly and easily elevated to facilitate work thereon.  The preferred support stand in-cludes a relatively wide base having an elongated, transversely extending beam secured thereto; a pair of padded vehicle-engaging members are shiftably mounted on the beam and are spaced apart a distance greater than the effective width of the base.  In this manner the center of gravity of a supported vehicle lies in a plane which passes between the lateral side margins of the base, even in the event that the stand or vehicle-engaging members are located asymmetrically relative to the underside of the vehicle.  This stand configura-tion also ensures that the vehicle and stand will right themselves during initial setup, which generally involves sideways elevation and tilting of the vehicles, placing a pair of the support stands beneath the vehicle in a similarly tilted orientation, and lowering the vehicle to effect reverse tilting of the vehicle and stands until the same are righted and the vehicle is elevated.     *

Abstract: ABSTRACT OF THE DISCLOSURE         Solid-state image pickup apparatus, such as an MOS imager, has a two-dimensional array of picture element units each formed of a photo sensitive element and a gating element, and scanning circuits for supplying horizontal and vertical scanning pulses.  The picture unit elements in turn discharge a signal charge onto vertical and horizontal transmitting lines in response to the vertical and horizontal scanning pulses.  Then, a resulting signal current is used to develop an output video signal.  In order to provide a strong output video signal with a good S/N ratio, a current mirror circuit, formed of an input transistor and an output transistor with first current-carrying electrodes joined together to a voltage reference point and with control electrodes joined together, amplifies the signal current.  A second current-carrying electrode of the input transistor receives a constant current from a current source and also receives the signal current.  The output transistor has a second current-carrying electrode connected to an output load.  Another current source can be connected to the output transistor so that only AC current will flow to the output load.  The output load can be a load capacitor associated with a pre-charging transistor, or can be a serial charge transfer device.                          -i-

Abstract: ABSTRACT OF THE DISCLOSURE To provide for effective sealing of a movable piston in a cylinder formed with a longitudinal slit, a motion transfer element is coupled to the piston and extends through the slit.  The transfer element is shaped in the form of a yoke extending over and around the outer surfaces of the cylinder tube to retain the portions of the tube separated by the slit   The slit is sealed in the regions between the closed ends of the cylinder and the piston heads of the piston by a pair of separable and re-engageable plastic strips.  The inner strip is formed with a projecting beaded rib fitting in a snap-in groove defined by two legs extending from the outer strip.  Upon movement of the piston a wedge-shaped separating element separates the interengaged ridge-groove combination ahead of the movement, and a top pressing element coupled to the yoke re-seals the beaded rib in the groove at the trailing side to form sealed cylinder chambers and to retain the cylinder chambers in sealed con-dition upon movement of the piston, and with it the yoke and the separating wedge.  The strips may be made to plastic to permit resilient deflection and engagement of the rib in the groove.

Abstract: METHOD FOR OPERATING A STEAM TURBINE      WITH AN OVERLOAD VALVE            Abstract of the Disclosure A method is disclosed for operating a steam turbine using turbine reserve capacity for attaining operation at elevated loads.  In a preferred form of the invention, a bypass overload valve is provided in parallel with the steam admission control valves but is connected to discharge steam to a lower pressure stage of the turbine.  During operation of the turbine at less than full load, the bypass overload valve is maintained closed and the control valves are positioned to sustain a preselected load.  As load on the turbine increases, the control valves are increasingly opened until they have all reached their fully opened position corresponding to a nominal rated capacity of the turbine.  Then, at the discretion of operating personnel, the bypass overload valve is fully opened while simul-taneously one or more of the control valves is throttled to offset any steam passing through the bypass overload valve in excess of the amount required to sustain the preselected turbine load.  A throttling reserve is thus established on the control valves which may then be positioned toward their fully opened position to achieve greater power output.

Abstract: Abstract of the Disclosure This invention relates to a device for applying a sterile liquid to a sore or a part of the body such as the eye.  A container having a container body made of flexible material is provided with an outlet equipped with a tubular emptying device which is provided with a breakoff weakening zone.  Adjacent to the outlet there is a contact member with one or more strip-shaped contact surfaces.  The breakoff weakening zone is located closer to the container body than the contact surfaces.  The contact member is provided with drainage openings in the area between the contact surfaces and the point at which the member is attached to the container body.  To apply sterile liquid to the area being treated, the emptying device is broken off at the breakoff weakening zone and, after being broken off, the emptying device is directed towards the area to which the liquid is to be applied.          The flexible container body is squeezed and the liquid is pressed out through the broken-off emptying device.          The contact member prevents direct contact between the sore or other part of the patient's body being treated and the tubular emptying device, and simultaneously the applied liquid is drained from the area being treated by means of the drainage openings.  This invention minimizes risk of mechanical injury to the area being treated and minimizes risk of contamination of the sterile liquid.

Abstract: ABSTRACT        A diode driver circuit for driving P-I-N diodes is disclosed. A differential pulse amplifier has   two input terminals to which signals 180° out of phase with each other are applied.  The amplifier has two outputs providing mutually 180° voltages.  One of the outputs is connected to a low impedance transistor circuit and the other through a capacitor to another transistor operating as a constant current source.          The cathode of the diode is connected to both the low impedance circuit and the constant current circuit.  The constant current circuit operates to supply an excess current for only a short period from the time the diode is biassed from the reverse to the forward direction. The current allows switching of the diode at high speed with little jitter.          Power consumption of the circuit is low.

Abstract: ABSTRACT OF THE DISCLOSURE A method of correcting errors in a digital television signal comprises forming the data words of the television signal into correction units each of which comprises a plurality of the data words and a parity word formed therefrom, and recording and subsequently reproducing on a digital video tape recorder the correction units. On slow motion reproduction from the digital video tape recorder a syndrome generator derives a syndrome from the data words and the respective parity word of each reproduced correction unit. An error counter counts the number of valid words in each reproduced correction unit. If this count is one less than the total number of words in the correction unit, the syndrome is used to correct the data word which is in error, and if the count is equal to the total number of words in the reproduced correction unit and the syndrome is not equal to zero, each of the data words in the reproduced correction unit is flagged as being in error.
