Title: High frequency parametric voltage regulator
IPC: G05F1/38
Filed: 1969-10-30
Abstract: 1287133 Automatic voltage control WANLASS ELECTRIC CO 30 Oct 1969 [30 Oct 1968] 53222/69 Heading G3R [Also in Division H2] A voltage regulator comprises a parametric device having at least two windings, one of which is an input winding connected to a source of high frequency alternating voltage derived from an unregulated voltage supply and the other of which is an output winding coupled to a capacitor to form an energy storing tank circuit oscillating at a stable point and providing isolation of the output from the input such that regardless of the input, the output is determined by the tank circuit, the device operating such that the flux generated by either winding does not normally link the other winding, and the output winding being connected to an output circuit whose voltage variations are sensed to provide an error signal which is used to vary the frequency of the high frequency source to maintain the output circuit voltage at a desired value. The output voltage is DC obtained by rectifying and filtering the voltage of the output winding. In Fig.3 the parametric device is generally similar to that described in Specification No. 1206279 and comprises a variable inductor 53 and a capacitor 55 of which the inductor is generally similar to that described in Specification No. 1153901. A low frequency A.C. supply 48, 49 is rectified and filtered at 50 and passed to an inverter 51 (see Division H2) whose high frequency supply is fed to the input or control winding 52 of the inductor 53. The output from the energy storing tank circuit 54, 55, which is turned to the frequency of the inverter 51, is rectified and filtered to provide a D.C. voltage 57, 58, which is fed to a control amplifier and oscillator 59 providing an error signal in the form of a variable frequency pulse train. The latter controls the frequency of the inverter 51 through a variable frequency drive and delay logic 60, Fig. 5 (not shown) which ensures that short circuit conditions in the inverter 51, due to simultaneous conduction of its alternately conducting elements, cannot occur. In another embodiment, Fig. 2 (not shown) the output winding is tapped to provide the voltage for rectification and the inverter comprises silicon controlled rectifiers controlled by a conventional comparator circuit. A starting circuit is provided to reduce the output frequency of the inverter to initiate oscillations in the parametric device. Alternatively this may be accomplished by overdriving the input winding to cause transient mutual inductance between the two windings.

Unloader and supply or check valve for compressor or pump systems or the like, comprises a valve body 1A, 1B with a through bore terminating in an inlet 5 and outlet 7 at opposite ends. A hollow piston valve member 41 is slidable in the bore and movable by fluid pressure to establish communication between the inlet and outlet through ports 19 in the valve member. In closed position as shown, the compressor or pump is unloaded through these ports, via a bleeder port 11 in the valve body. This port is obturated by a sleeve 13 which has a sliding lost-motion connection with the valve member 41. Movement of the valve is damped by an integral collar 17 on the valve member 41, this collar being a leaky sliding fit in the bore and the sleeve 13 also being a leaky fit so that fluid has access to both sides of the collar. As shown, the piston valve is sealed by an 0-ring 55 and the device is adapted to function as a check valve. In a modification however, an axial port (59), Fig. 5 (not shown), opening through the end 15 of the valve member 41, is provided so that the system on the outlet side 7 of the valve is also unloaded in the position shown. The unloading and bleed ports also serve to clear away condensation on re-starting a compressor.

Abstract: 1,194,839. Incinerators. DOWSON & MASON Ltd. 20 Dec., 1967 [9 Dec., 1966] No. 55316/66. Heading F4B. An incinerator for use in a multistorey building has a charge shoot 2 extending from all the floors and having a valve closing its discharge end, a combustion chamber with a dumping grate 6 and a burner 5, and an ash container 7 below the grate, the arrangement being such that the grate 6 cannot be dumped unless the short valve is closed and the ash container is in position. The gases from the combustion chamber pass to a secondary combustion chamber 10 and through a water spray compartment 12 before being exhausted to the flue by a fan. A burner 11 in the secondary combustion chamber is controlled in accordance with the temperature in the main combustion chamber, and the water spray is increased as the flue gas temperature rises. Condensate from the flue drains to the base of the flue compartment. The incinerator is operated by a series of timers, one allowing operaion of the incinerator for a set period during each 24 hours, a second timer switching on the ignition burner 5 for brief periods at set intervals during the period of incinerator operation, and a third timer arranged to switch off the exhaust fan and allow hot gases to flow up the shoot 2 to cleanse it at the end of the operating period set by the first timer. After the shoot 2 has been cleared, the shoot valve is closed and the grate 6 is dumped. A limit switch engaged by the ash bin 7 prevents operation of the grate 6 unless the bin is in place. A gate 19, enclosing the bin, can be opened by a key held in a control panel, from which it cannot be removed before the expiry of a set delay after the key has been turned in the panel to close the shoot valve and cut off the burners. The fire door of the main combustion chamber may be locked by the same key.
