Abstract: Abstract Simplified Double Balanced Frequency Converter A simplified, compact, flat microwave frequency converter assembly utilizes a flat quad diode bridge, and has two pairs of opposed flat conductors, each with a respective one of the opposed conductors on a respective side of a flat dielectric substrate.  Each of the pair extends orthogonally from their inter-section at the bridge.  The bridge is connected at opposite corners thereof to adjacent ends of the conductors at the intersection on a first side of the substrate.  These first-side conductors are in electrical continuity with a conductive layer ex-tending about the periphery of the substrate on the first side thereof.  This layer is, in turn, in contact with a conductive carrier plate by means of which the layer is grounded.  On the second side of the substrate, each of the pair of capacitors affixed to the substrate is connected between respective opposite corners of the bridge, and the adjacent ends of the conductors of one of said pairs.  In this manner, two pairs of input baluns are provided to accept, for example, an input RF signal, and a local oscillator signal.  An output conductor pair is provided, each extending outwardly on the sub-strate first face from one of the bridge opposite corners to terminals between the bridge and con-ductive layer, each then continuing on the second face from the terminals to a junction adjacent the substrate edge, and serving as an output from which a heterodyned signal may be obtained.

Abstract: COMBINED RADIANT AND FAN HEATER              ABSTRACT OF THE DISCLOSURE         A combined portable radiant and space area heater is provided, having a radiant heating means combined with a fan operable in at least a slow speed and a high speed mode.  Operating in the low speed mode, the fan serves to locally recirculate heat provided by the radiant heating means, while permitting the heating means to maintain a high temperature with consequent high radiant heat output, suited for use primarily by an individual.  In the low speed fan mode the recirculated air affects the temperature of a thermosensitive sensor, so as to control the energization of the heating means in the event that a limiting temperature of the sensor, indicative of local conditions, is exceeded.  In the high speed mode of fan operation the temperature of the radiant heating means is effectively reduced, to significantly diminish the extent of heat radiation, the output instead being effected by high velocity dispersal of hot air, in a space area heating mode.

Abstract: ANTI-SNAP DEVICE OR DRAFTING   BOARD TILTING MECHANISM                ABSTRACT OF THE DISCLOSURE           A drafting table having spring-balanced lifting and tilting movement features is provided with an anti-snap device which prevents the table top from tilting so quickly to the full-vertical position that it hits its stops and rocks the entire table over.  The anti-snap device comprises a flexible strap which is wrapped about and fixed to cylin-dric members on which the table top lifts and tilts.  The flexible strap becomes tight as the table top reaches its fully vertical position, but tightening of the strap is resisted by the lilt springs, which are pulled to one side by the strap.  Resistance to the tightening of the strap requires more force to tilt the top to its full vertical position, increasingly slowing the tilting movement near the end of tilting travel.
