Abstract: PRODUCING A REPLICATE VIDEO DISC BY A METHOD OF PHOTOGRAPHIC CONTACT PRINTING                Abstract of the Disclosure A photographic contact printing process is dis-closed having application in the mass production of replicate video discs from a master disc, and other applications wherein it is desired to replicate micro-detail over a relatively large area.  A problem with con-ventional contact printing from a mask to a photographic medium is one of maintaining intimate contact over a relatively large area since dust, dirt, etc., are almost impossible to completely eliminate in any practical manner.       In accordance with the present invention, a contact print-ing process is proposed wherein intimate contact is not necessary for making high quality contact prints.  The present invention recognizes that in contact printing information from a master disc to a replicate disc, the contact printing process is significantly less sensitive to imperfect contact between the master disc and the replicate disc if one employs a replicate disc comprising a photosensitive material having certain optical properties.          In particular, the photosensitive material initially has a high level of absorption to the actinic radiation used for exposure but, under the influence of such actinic radiation, the absorption decays to a lower level during exposure.

Abstract: Abstract of the Disclosure A steering gear system includes a rack driven by a pinion.          When the torque on the pinion reaches a predetermined level, the steering column to which the pinion is attached moves axially.  The axial movement of the steering column brings a disc connected with it into electrical conductive contact with a fixed electric contact.  This energizes an electric motor.          Further axial movement of the steering column causes the disc to contact a friction clutch plate which is connected with a pulley driven by the electric motor.  This results in frictional engagement between the disc and the friction clutch plate and a power assist from the electric motor to move the rack which is a function of the torque applied to the steering column.

Abstract: TITLE   QUICK DISENGAGING VALVE ACTUATOR                   ABSTRACT OF THE INVENTION An actuator is provided which is respondable to control fluid pressure for moving an operative means of a valve between open and closed positions.  The actuator comprises a housing having a cylin-drical bore defined therethrough.  A shaft is carried in the hous-ing and is engagable with the operative means.  Piston means are carried by one of the shaft and the housing and are sealingly slidable along the other of the shaft and the housing and longi-tudinally movable within the cylindrical bore.  Fluid chamber means are companionly associated with the piston for yielding a differential force across the piston means upon variation of fluid control pressure within the actuator.  The shaft is selectively shiftable longitudinally in a first direction to move the opera-tive means to one of open and closed positions by variation in fluid control pressure, and is shiftable to a second direction to move the operative means to the other of the open and closed positions upon subsequent variation in fluid control pressure.  One of the shaft and operative means has slotted means thereon for transverse receipt of a companion engagement means on the other of the shaft and the operative means whereby the operative means and the shaft are thereafter in substantial longitudinal engagement.  The shaft and the operative means are disengageable by relative transverse shifting of the shaft and the operative means to remove the actuator from the valve.

Abstract: ABSTRACT OF THE DISCLOSURE     Known electronic countermeasures systems have difficulty handling some modern radar signals, for example frequency agile, frequency sliding or frequency coded signals.  The invention disclosed overcomes the problems of the prior art by using an analog frequency dividing system to virtually instantaneously down-convert received signals in octave steps and in octave stages into the frequency regimes associated with the operation of processing devices, such as analog to digital converters, digital logic devices, surface acoustic wave devices, and charge coupled devices.  Those processed signals which are selected for retransmission, perhaps in a modified form, are then up-converted into the region of the received signal by the appropriate number of stages of frequency multipliers.  Any modification in such signal parameters as signal duration, delay, frequency, phase, power, amplitude or spectral content may be incorporated prior to the first multiplication stage, between multiplication stages, after the last multiplication stage, or any combination of the above.

Abstract: Abstract of the Disclosure This invention is concerned with photographic products, particularly diffusion transfer photographic film units, useful in photographic processes conducted outside of a camera wherein post-exposure fogging by ambient light is prevented by a compound initially present as a substantially colorless compound which is activated by base to provide a light-absorbing reagent or colored optical filter agent which is capable of  being irreversibly discharged without a change in pH.  The colorless compound or filter agent precursor is initially disposed in a layer of the film unit, for example, in a layer coated over the photosensitive element.  Subsequent to imagewise exposure of the photosensi-tive element, the colored optical filter agent is generated by contacting the colorless precursor with a basic processing composition.  After remaining in contact with said basic composition for a given time, the colored optical filter agent is discharged by forming a new compound which is substantially colorless and which is different from and non-reversible to said precursor and different from and non-reversible to said optical filter agent.

Abstract: 47,719 HIGH FREQUENCY ELECTRODELESS LAMP   HAVING A GAPPED MAGNETIC CORE     ABSTRACT OF THE DISCLOSURE           High frequency electrodeless (HFE) lamp has high-permeability core such as ferrite at least partially posi-tioned within the phosphor-coated lamp envelope.  The core forms a part of a tuned circuit output for a radio-frequency energizing source and during lamp operation, the resulting electromagnetic fields generated within the lamp envelope create a discharge which in turn generates radiations to excite the phosphor to produce visible light.  The core is specially designed to include a narrow gap of low-perme-ability substance and this gap improves lamp performance by providing the dual function of stabilizing the output fre-quency of the tuned circuit to compensate for variations in permeability of the core and, in addition, the resulting increased Q of the tuned circuit substantially suppresses harmonies of the resonant frequency which are undesirable in such a lamp.
