Abstract: Systems which have an integrated unit that allows both television signals and information retrieved from an onboard information storage device to be presented in visual, audio, or visual/audio form via output devices such as television screens and audio speakers. The operating mode--television or stored information retrieval and display--is selected by the user. The user is coached through steps leading to retrieval and presentation of the wanted information if the information retrieval mode is selected. A novel remote control allows the system user to choose the mode of operation and to navigate the steps needed to reach the wanted information from a location convenient to the user.

Abstract: Bagel cooking apparatus which has a casing and a bagel boiling section provided by a water-containing component removably supported from the casing. An oven section in which boiled bagels are baked is located beneath the bagel boiling section. Independently controllable heaters may be provided to boil the water and to bake the bagels or a single heater may be employed for both of those purposes. In the latter case, the removable, water-containing component is constructed so that it can be associated with the casing in two different orientations in which that component respectively directs heat primarily to the bagel boiling section of the apparatus and to its oven section.

Abstract: An appliance which includes an inner compartment with one zone in which uncooked bagels can be boiled and a second zone for subsequently baking the boiled bagels. The same appliance can also be used to make bagel doughs and to both make and bake other yeast doughs.

Abstract: An appliance which includes a casing divided into one zone in which uncooked bagels can be boiled and a second zone for subsequently baking the boiled bagels. The same appliance can also be used to make bagel doughs and other yeast doughs. In the dough making mode, a bagel rack and its support are removed from the casing and replaced with a dough container and a dough mixing and kneading blade.

Abstract: Bagel cooking apparatus which includes a casing divided into a lower zone in which uncooked bagels can be boiled and an upper, oven zone for subsequently baking the boiled bagels. A cam mechanism with an externally accessible operator is provided to move a bagel-supporting structure housed in the casing between the lower, boiler zone and the upper, oven zone. A control system allows a user to independently control the operation of the bagel cooker during the boiling and baking steps.

Abstract: Apparatus for extracting juice from comestibles such as fruits and vegetables. The extractor has a base which includes a motor with a vertically oriented output shaft and a housing for the motor. A blade basket detachably mounted on and driven by the output shaft comminutes the comestibles and extracts their juice, and a juice bowl surrounding the blade basket collects the juice. A safety interlock keeps the motor from being turned on unless the juice bowl is locked to the base of the juice extractor and a blade basket isolating cover is locked to the juice bowl.

Abstract: Controls for the electric motors of juice extractors and other devices. The control keeps the motor at a constant speed under changing loads, and the control may allow the operator to select one of multiple operating speeds. Typically, the control will also include a safety switch which keeps the motor from being energized unless conditions consonant with safe operation of the device powered by the motor have been met.

Abstract: Apparatus for extracting juice from produce such as fruits and vegetables. The extractor has a base which includes a housing and a motor with a vertically aligned drive shaft. A blade basket detachably mounted on and driven by the output shaft separates produce into pulp and juice, and a juice bowl surrounding the blade basket collects the juice. The juice bowl is mounted on the base of the apparatus such that rotation of the bowl in a first direction relative to the base locks the bowl to the base. Rotation of the juice bowl in the opposite direction out of the locked position lifts the bowl away from the base and uncouples the blade basket from the drive shaft. An interlock system keeps the motor from being turned on until the juice bowl is locked to the base and a cover is locked onto the juice bowl. Performance is enhanced by, inter alia: anti-splashing provisions and vibration absorbing components which isolate the motor and the motor driven components of the apparatus.

Juice flows from the juice bowl through a spout to an appropriate container. A spray cap keeps juice from splashing as it pours through the spout.

Abstract: A microwave microstrip/slotline frequency-halving circuit configuration is disclosed in which the frequency division is based on the principle of parametric subharmonic generation. The circuit comprises a subharmonic resonator formed partially by the overlap of an open-circuited microstrip line on one side of a dielectric substrate and a short-circuited slotline in the ground-plane on the other side of the substrate. The resonator is completed by a pair of varactor diodes symmetrically placed in holes in the dielectric substrate so as to form connections between the end of the microstrip line and the two sides of the slotline below. An input signal at frequency 2f entering via the microstrip line results in the propagation of a signal at frequency f in the output slotline.

Abstract: The invention relates to a broad bandwidth frequency divider which converts a band of input frequencies into a band of output frequencies such that each output frequency is one half the corresponding input frequency. The frequency divider has a first rectangular waveguide which propagates the band of input frequencies and a second larger rectangular waveguide which propagates the band of output frequencies. The two waveguides are orthogonally disposed with respect to one another and are interconnected by a slot provided in a common wall. Two nonlinear capacitive reactances are mounted in the first waveguide, one on each side of the slot, forming a transverse resonator. When the two nonlinear reactances are pumped in phase at the input frequency, parametric subharmonic resonance can be excited transversely at one half the input frequency such that the nonlinear reactance voltages are 180.degree. out of phase at the output frequency.

Abstract: A broad band frequency divider in which microstrip or stripline transmission lines and more than one microwave varactor diodes are interconnected to form a circuit which is resonant at a frequency of one-half of the input signal frequency and whose output consists substantially of odd order harmonics of one-half of the input frequency, the even order harmonics being virtually eliminated. An unbalanced output signal is achieved through the use of a coplanar balun. An optional DC external bias may be applied to the varactor diodes.
