Title: Cantilever springs in a strong-box
Inventor: COLLINS JOHN
IPC: E02D17/08
Filed: 1989-05-03
Abstract: A strong-box comprises panels interconnected by struts (400) which are connected to the panels (200) by universal joints (500) and also by leaf springs (600). In order for the leaf springs to absorb twisting with the universal joints (500), the springs (600) are split into two side-by-side leaf springs (600a, 600b).

Title: Pulse generation and tracking system
Inventor: STUBBERS RON
IPC: G01R19/25
Filed: 1989-07-28
Abstract: In a pulse generation and tracking system for connection to a subject (94) under treatment, the positive polarity portion of an applied current pulse is sensed (96, 98), integrated (118), and averaged (120, 122, 190) by dividing the integrated value by the portion width; and the positive portion of an applied voltage pulse is sensed (132) and averaged in a long time constant CR circuit (130, 128). Each pulse (Fig. 5 not shown) comprises a large amplitude, short duration positive portion and a small amplitude, long duration negative portion, and a zero portion. The impedance of the subject changes over time and causes pulses to vary from predetermined desired limits. When this occurs subsequent pulses are changed accordingly (Fig. 9 not shown). Pulses are generated (Fig. 6 not shown) by switching between positive, negative and zero voltage levels, as required. <IMAGE>

Title: Streamlined flapper valve
Inventor: SMITH RODDIE R
IPC: E21B34/06
Filed: 1991-08-23
Abstract: A subsurface safety valve has a valve seat (74) and an upwardly closing flapper plate (52) whose sealing surfaces (74S, 52S) each have a matched spherical radius of curvature (R). The sealing surface (74S) of the valve seat (74) is a concave spherical segment and the sealing surface (52S) of the flapper plate (52) is a convex spherical segment. The matching spherical surfaces are lapped together to provide a metal-to-metal seal along the interface between the nested convex and concave sealing surfaces. This permits angular displacement of the flapper plate (52) relative to the valve seat (74) without interrupting positive sealing engagement. The concave spherical seating surface (74S) of the safety valve seat (74) will tolerate a limited amount of misalignment of the flapper plate (52) which sometimes occurs during operation of the safety valve (10) under high flow rate, high differential pressure conditions. <IMAGE>

Title: Driver circuit for piezoelectric element, having voltage limiter capable of charging the element with energy from coil after charging switch is off
Inventor: SUZUKI MASASHI
IPC: H01L41/09
Filed: 1991-10-09
Abstract: A driver circuit for a piezoelectric element P having capacitance C, including a DC power source 50, a coil 51 having inductance L, a voltage limiter, and a first and a second switching device T1, T<2> for charging and discharging the element, respectively. The first switching device is held on for a time not shorter than ( pi  2ROOT LC)/3 and is turned off at a first point of time before a voltage of the piezoelectric element has reached a predetermined level not higher than a line voltage of the power source. The voltage limiter allows the element to be charged with an energy stored in the coil after the charging by the first switching device, and prevents the element from receiving an excessive energy that causes the voltage of the element to exceed the predetermined level. The second switching device is turned on at a point of time not earlier than the first point of time, and is turned off by the time when the first switching device is turned on for a next activation of the element. <IMAGE>

Title: Membrane seal assembly for a pulsed rocket motor
Inventor: HUMISTON ROBERT G
IPC: F02K9/28
Filed: 1991-10-11
Abstract: A membrane seal assembly separating forward and aft combustion chambers 20, 18 of a rocket motor. The assembly covers the aft surface of a bulkhead 32 having apertures 34 therein to preclude flow communication between the combustion chambers during combustion of propellant 24 within the aft combustion chamber. The assembly includes a membrane 38 which has a plurality of sectors which open along hinge lines away from the bulkhead to allow flow communication between the combustion chambers when a higher pressure is present in the forward combustion chamber than in the aft combustion chamber, i.e., during subsequent combustion of the propellant in the forward combustion chamber. The sectors are provided by a plurality of radially extending slits 104 in the membrane which are formed entirely through the thickness of the membrane so that complex scoring tooling and close tolerances of manufacturing membranes with score lines is not required. The membrane is covered with a layer 40 of insulating material. The pattern and sizing of apertures 34 in the bulkhead is such, for an erodible bulkhead, that each aperture erodes into the adjacent eroding apertures in such a manner as to minimize the size of debris breaking away from the bulkhead to reduce the possibility of debris becoming lodged in the nozzle throat.

Title: Fuzzy feedback controller
Inventor: SHINMURA KAZUTAKA
IPC: G05B13/02
Filed: 1992-08-28
Abstract: In a fuzzy feedback controller a deviation, e, between a process value, x, and a set value, r, and a variation of the deviation, DELTA e, are obtained with the aid of an arithmetic memory device 11, and the deviation and the variation of the deviation are normalized with normalizing devices 13 and 14. A fuzzy inference operating device 15 performs a fuzzy inference by using the deviation and the variation of the deviation thus normalized, to obtain a control output variation,  DELTA u. The control output variation is normalized by another normalizing device 18. The control output variation  DELTA u thus normalized is added to the preceding control output in an addition device 19, to form a new control output, which is applied to an operating device 20. A parameter adapting device 17 makes normalizing parameters adaptive according to the response waveform of the process value. <IMAGE>
