Abstract: TITLE:  ROTATABLE TOOL POWER LOCK RETENTION         APPARATUS FOR FOOD PROCESSORS       INVENTOR:  KOICHIRO SHIBATA                         ABSTRACT           Rotatable tool power lock retention apparatus for food processors having a working bowl with a vertical motor-driven shaft extending up into the bowl and in which a rotatable tool has a hub removably engaging upon this shaft in driving relation with the shaft.  The tool has at least one outwardly extending food processing blade secured to the hub, such as cutting and chopping blade or a dough mixing and kneading blade.  During a food processing operation, the rapid rotation of the tool blade with respect to the food being processed often creates a dynamic lifting action on the blade, thereby tending to raise or elevate the hub upward along the drive shaft.  The present tool retention apparatus prevents the hub from being lifted upwardly relative to the drive shaft during operation and yet it enables quick, easy installation and removal of the tool.  This power lock tool retention ap-paratus includes at least one flattened section on the drive shaft with an associated horizontal notch.  A socket extend-ing downwardly from the top on the inside of the hub is adapt-ed to receive the drive shaft during manual installation of the tool so that rotation of the shaft will cause the tool to be rotated.  At least one horizontal lip is provided in the socket at an elevation to become aligned with the notch on the drive shaft when the hub has been slid down vertically into its operating position on the shaft.  The socket configuration is complementary to, but slightly dif-ferent from, the flattened configuration of the drive shaft in order to permit a small amount of relative  angular move-ment between the shaft and hub when the shaft commences to rotate.  This small relative rotation produced by the torque of the motor drive when the food processor is started causes the horizontal lip to engage in the horizontal notch as the shaft starts to be rotated, thereby locking the tool onto the shaft during operation for preventing the hub from being dynamically lifted.  When the food processing operation is finished, the food processor is stopped, allowing ready dis-engagement and removal of the tool from the drive shaft by manually turning the tool in the opposite direction through the same small amount of angular movement relative to the shaft for disengaging the lip from the notch, thus permitting vertical lifting of the tool off from the shaft. The rotatable tool retention apparatus prevents the hub from being dynamical-ly lifted upwardly relative to the drive shaft and becomes automatically locked and unlocked by the starting and stopping of the food processing apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE   Printed circuit boards are carried generally vertically, along a path, with the tabs at the lower end being immersed in an electrolyte.  The boards are automatically conveyed through opposed serially arranged pairs of rollers, which drive them along their path. Brushes wipe the boards to prevent contact with electrolyte above the desired contact level, as they are conveyed along the path.  The solution is constantly replenished and turbulence pro-vided by delivering electrolyte solution, with insoluble metallic ions in it, by pumping the solution from a sump, through an array of nozzles along each side of the path, thus providing fresh electrolyte along with providing tur-bulence to the electrolyte.  The nozzles are charged at a sufficiently low level to avoid their destruction.  Electrical contact is made with the printed circuit boards, by means of serially engaging the boards with spring fingers of a continuous conductor along each side of the boards as they are conveyed along their path, and thereby conducting the applied charge to the immersed tabs, whereby the tabs function as cathodes for electrodeposition of metallic ions thereon. The drive for the boards is provided by means of opposed pairs of rollers.  One roller in each pair is a driving roller, with the opposing roller functioning as an idler, but forming an interference fit between the rollers as the boards are carried therebetween.  The idler rollers are arranged in a bank, for adjustably being positioned to accommodate boards of various thick-nesses.  The electrical connection with the upper ends of the boards may like-wise be adjustably positionable to accommodate boards of various heights.

Abstract: LOW NOISE OSCILLATOR             ABSTRACT A low noise oscillator.  A circuit config-uration is provided for reducing noise sidebands in the output of an oscillator due to modulation of the oscillation signal by characteristic noise produced by the amplifying element.  A gallium arsenide field-effect transistor that produces characteristic noise is operated as a linear amplifier.  Positive feedback to the input of the amplifier is provided by a resonator. The amplitude of the oscillation signal is limited by a distinct limiting circuit in the feedback loop, the input to which is isolated from the amplifier by a high pass filter, thereby divorcing the non-linear limiting function of the oscillator from the amplifying function where noise is generated.

Abstract: METHOD AND APPARATUS FOR DESKEWING WDM DATA  TRANSMITTED THROUGH A DISPERSIVE MEDIUM                         Abstract When a byte of digital data is transmitted through a dispersive medium using frequency or wavelength division multiplexing (WDM) techniques, individual bits in the byte are normally delayed different amounts of time.  This is referred to as bit skew.   WDM apparatus is described along with a system for deskewing WDM data received after transit through a dispersive medium.  Two bits in a given byte of data are detected.  The relative times of arrival of the remaining bits in a byte are predicted using the relative delay between the two detected bits and the known frequency-related dispersion characteristics of the transmission medium. Certain bits in each received byte may be delayed using clock delay lines or registers to reduce the amount of time skew between the various bits in a byte.

Abstract: RCA 81,988 Abstract In a superheterodyne receiver, such as a typical television receiver, a radio frequency coupling arrangement includes a first resonant circuit coupled to receive the input signal and further coupled to a second resonant circuit by a first coupling.  Both resonant circuits are tuned to the desired signal frequency.  The capacitive branch of the first resonant circuit includes a circuit impedance for providing a neutralizing voltage, at least a portion of which is coupled by a second coupling to the inductive branch of the second resonant circuit. The circuit impedance is selected to cause cancellation in the inductive branch between image frequency components coupled by the first coupling and image frequency components coupled by the second coupling, without substantially affecting the desired signals.
