Abstract: Abstract Output gate electrode structure between the storage matrix and the output register of a serial-parallel-serial (SPS) charge coupled device (CCD) memory. To permit high channel packing density in the matrix, the output register can have as few as M/N stages, where M is the number of channels in the matrix and N the number of phases employed for operating the register, The gate structure transfers 1/N'th of a word at a time to the output register and while this 1/N'th of a word is being propagated out of the register, the remaining part (or parts), if any, of the word are stored while the gate structure provides a potential barrier between this stored charge and the register.

Abstract: BIOLOGICAL INTERMEDIATE SEWAGE TREATMENT WITH OZONE PRETREATMENT            Abstract of the Disclosure A process for intermediate treatment of aqueous sewage containing biodegradable materials and non-biodegradable materials.  The sewage is contacted with an ozone-containing gas to pretreat the sewage by converting a substantial amount of the non-biodegradable material to biodegradable material, followed by a conventional secondary treatment with an O2-containing gas such as air in the presence of aerobic or facultive anaerobic micro-organisms.    The process may also include subsequent tertiary treatment with ozone to destroy the micro-organisms after secondary treatment.  A relatively small amount of the overall oxidizing gas requirements is provided by ozone.  The secondary treatment is made more efficient by the ozone pretreatment.

Abstract: ABSTRACT        The invention relates to a capacitively stabilised discharge lamp, that lamp being shunted by inter alia a coil. During the starting procedure of the lamp that coil is brought to saturation, whereby means of resonance with the capacitive to start it. According to the invention the B-H magnetisation curve of the coil has been chosen so that a transition from the unsaturated condition to the saturated condition also occurs dur-ing the operating condition of the device, namely just before the moment the lamp is extinguished during each half cycle of the supplying a.c. voltage. Consequently the ratio of the r.m.s voltage of that a.c. voltage source to the operating voltage of the lamp may be relatively small. A resistor having a positive temperature coefficient which shunts the lamp and is in series with the coil, limits the electric current if the lamp refuses to start.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a monitor for controlling the dose of applied radiation to, for example a patient.  The monitor is comprised of a dose rate frequency changer which is connected to a pulse counter.  The counter is connected to a comparator which is activated to control an off-switch for the radiation when the pulse count reaches a predetermined count.  A second pulse counter is connected to the changer.          This counter operates when the radiation is off.  As a result any count obtained is a result of component drift in the radiation detector and the changer.  The count is converted to an analog signal, inverted and fed back to the input of the changer to compensate for the above-mentioned drift. Once this drift has been stabilized by the feedback loop the radiation is turned on and control of the dosage is handled by the first mentioned counter comparator and off-switch.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a novel high speed method for the formation of an electrostatic image in a photosensitive plate comprising a grounded conductive substrate having on its surface a layer of photoconductive material overcoated with a layer of an insulating resin.  The process involves the consecutive steps of: a) applying an initial electrostatic charge of one polarity to the surface of the plate to provide an initial potential which is solely across the insulating layer; b) applying an electronic field of either alternating current or direct current of polarity opposite that of the polarity of the initial charge to drive the initial potential to a potential included in the range extending from a potential less than the initial potential through zero to a chosen potential opposite in sign to the polarity of the initial potential; c) exposing the plate to imagewise activating radiation thereby forming an imagewise potential distribution across the layer of photoconductive material; d) applying to the surface of the plate an electronic field of either alternating current or direct current of polarity opposite that of the polarity of the initial charge to drive the imagewise potential to a potential included in the range extending from a potential less than the initial potential through zero to a chosen potential opposite in sign to the polarity of the initial potential; and e) forming an imagewise potential distribution across the insulating layer by uniformly exposing the plate to activating radiation or allowing the inherent dark decay of the photoconductor to establish the imagewise potential distribution.

Abstract: WINDMILL ROTOR          Abstract An omnidirectional windmill rotor is formed of a number (preferably seven) identical blades arranged symmetrically around a vertical shaft to which their upper and lower ends are secured.  The blades are bowed outwardly at their wider central portions to define a sphere-like "chamber", each blade having a curved trailing edge projecting outwardly beyond the leading edge of the adjacent blade in order to form a "scoop" to receive the wind and induce rotation of the shaft.  The lower end of each blade is twisted to form a deflecting portion on which the wind impinges to generate an upward movement of air within the chamber, serving to lighten the weight of the rotor on its bearing.  In a modified version, a further project-ing secondary blade is secured to each main blade to enhance the scoop effect and to provide a gap between the main and secondary blades.  This gap causes a "jet effect" at low speeds, which improves the self-starting ability of the rotor under low wind velocities, and, at high speeds, causes a braking effect that protects against overspeeding.

Abstract: ABSTRACT OF THE DISCLOSURE            A PCM codec includes known parts used to convert analog signals to PCM words and vice versa.  At least one of the parts is used for both conversion types in spite of that the clock pulse frequencies of the incoming and outgoing PCM words are different.  A timing unit generates time intervals a first and second number of which is needed at the very most to carry out a conversion operation of the first and the second type, respectively.  The shorter of the period lengths determined by the two clock pulse frequencies includes at least the sum of said two numbers of time intervals.  A control unit receives the clock pulses in order to notify respective conversion type and generates conversion type signals by means of which each of said time intervals is associated with one of the two conversion types and the codec parts are configurated for the execution of respective conversion operation.  To master states where a type signal is generated delayed in relation to the notification pulse, the codec comprises information memories to store the influenced information.  To master states where the control unit interrupts the present conversion operations of the one type due to the priority of the other type, the codec  comprises a result memory to store such intermediate results which make it possible to continue the interrupted operation after the termination of the priority operation.
