Title: Unitary tuning structure
Inventor: HIETALA ALEXANDER W
IPC: H03K5/02
Filed: 1989-03-09
Granted: 1991-12-31
Abstract: Abstract An RF signal input circuit for a UHF tuner of a television receiver comprises a series-tuned circuit including a varactor diode and an inductance element connected in series, in the order named, between signal ground and a gate electrode of a field-effect transistor RF amplifier.  The series-tuned circuit has a relatively uniform bandwidth throughout the UHF range.  A capacitor connected in shunt with the gate electrode completes a "split-capacitor" configuration in which the varactor diode and the shunt capacitor form a variable impedance transformation network for making the relationship between the effective impedances of the series-tuned circuit and FET amplifier relatively uniform throughout the UHF range. The order of the varactor diode and inductance element allows a low cost adjustable capacitor comprising a grounded shield wall as one plate and a moveable tab as a second plate to be connected directly across the varactor diode.

The thermoelectric device acts as a gate or heat pump for controlling flow of thermal energy to and from the thermostatic bulb with a relatively small amount of electrical energy input.  Preferably, the thermoelectric heat pump device is positioned between the thermostatic bulb and the suction line of the evaporator so as to control transfer of thermal energy between the suction line and the thermostatic bulb.  Preferably, the control apparatus senses the temperature difference between the suction line and the inlet line of the evaporator and maintains the temperature difference within prescribed limits.

Abstract: A device for producing alternating electric current of high frequency for power consumers such as fluorescent tubes (Ly1, Ly2) comprises a transformer with a winding (n3) connected in series with an output terminal (e) and active electronic components such as transistors (T1, T2) controlling the output current, the transistors being controlled by electric voltages produced by inductive feedback in feedback windings (n11, n12). Magnetic saturation is utilized to modify the inductive relationship in such a way that the transistors (T1, T2) cyclically change the direction of the output current. The feedback takes place in two magnetic cores (Tr1, Tr2) of the transformer, each core being provided with at least one further electric magnetization winding designated a command winding (n5, n6) as electric current is fed through the command windings to control magnetic saturation of the magnetic cores (Tr1, Tr2). As a result, combined control of the frequency and of the active electric power in the fluorescent tubes (Ly1, Ly2) is possible so that the luminous power may be controlled over a wide range while suitably high voltages can be maintained to ignite the tubes properly.

Abstract: A fastener for sliding doors or windows comprises one or more bolt assemblies (8) having sprung loaded bolts with heads (15) mounted in housings set into the stile (7). The fastener also comprises a receiver assembly (9) including a pair of rails (23, 24) having similar aligned key-hole openings (25, 26) respectively. The outer retainer rail (23) is slidable relative to the inner rail by operation of an actuator (27) controlled by a handle assembly (10). When the bolt heads (15) are received in the aligned openings (25, 26) on closing of the stile (7) to the jamb, the handle (29) of the assembly (10) is turned causing the retainer rail (23) to move downwards to trap the heads (15) of the bolt in the narrower parts of each opening (25) in the retainer rail (23). The handle assembly (10) preferably includes a lock to prevent the handle (20) being rotated after locking. The spring loaded bolts provide a "buffer" action and prevent damage to the receiver assembly even if in the fastening position. The bolt assemblies may be mounted on a jamb with the receiver and handle assemblies on the stile.
