Patent GB-2253791-A (GB)
Title: An artificial leg
Inventor: SHORTER JOHN JEFFREY
IPC: A61F2/74
Filed: 1991-10-09
Abstract: An artificial leg includes a knee mechanism having means for restricting knee flexing movement during the stance phase of the walking cycle. The restricting means includes a piston and cylinder assembly so coupled in the mechanism that the piston is movable in the cylinder with knee flexion and extension. The knee mechanism includes two chassis parts arranged to move relatively to each other when an axial load is applied to the limb. One end of the piston and cylinder assembly is connected to one of the chassis parts while the other chassis part engages a control member coupled to a valve inside the piston and cylinder assembly so that the valve is operated in response to relative load-dependent movements of the chassis parts, in order to restrict the flow of fluid and thereby create resistance to knee flexion during the stance phase. The chassis parts are connected together by an anterior pivot joint and are resiliently moveable relative to each other according to applied load. The piston and cylinder assembly is also operable to resist movement during the swing phase of the walking cycle, and the interaction of the knee chassis parts with the control member is arranged so that movement of the member is reduced or does not occur at all for flexion angles greater than a predetermined value between 30 DEG  and 40 DEG . <IMAGE>

Title: Frequency synthesis in alternative frequency monitoring for cell phone.
Inventor: WARD TORBJORN
IPC: H04B17/00
Filed: 1992-02-19
Abstract: In a mobile radio communications apparatus, a communications reception frequency is generated and a time sequence of a plurality of reception monitoring frequencies is separately generated. Reception is switched between the communications reception frequency during communications reception and a current one of the monitoring reception frequencies during signal strength monitoring. Separate frequency synthesizers are provided for communications reception on the one hand and signal strength monitoring on the other hand. The frequency of the synthesizer for communications reception remains fixed during the course of a communication. The synthesizer for signal strength monitoring need not be as accurate as that for communications reception and since it is used only for signal strength monitoring instead of for both communications reception and signal strength monitoring, more time is available for switching between frequencies. <IMAGE>

Title: Piezoelectric mechanism for gas lighters
Inventor: MEURY MARCEL
IPC: F23Q3/00
Filed: 1992-03-03
Abstract: The piezoelectric mechanism for a gas lighter comprises a spring 20 which normally maintains, Fig 1, the maximum extension between an assembly 1 housing a piezoelectric element 3 between an anvil 4 and a base piece 5, and an assembly 2 housing a hammer 6 which is caused to hit the base piece 5 and thus the piezoelectric element to generate a spark ignition voltage. The assemblies 1 and 2 have square cross-sections and are prevented from relative rotation by an L-shaped angular element 22 (Figs 20-22), one arm of which has parallel lugs (24) which grip opposed notches (23, Fig 3- 5) in assembly 1 and is thereby fixed thereto. The other arm 27 of the element 22 extends from assembly 1 and overlaps one of the flat sides of assembly 2 thereby preventing relative rotation. The hammer 6 has diametrically opposed lugs 11 which are held in lateral notches (12, Fig 5) of long slots (13) in the assembly 1, and which extend through windows in the assembly 2. In operation, upon applying pressure urging assembly 1 towards assembly 2 the ramped edges 31 of the windows in the assembly 2 cause the hammer to rotate so that its lugs 11 come out of notches 12 into slots 13 and the resultingly compressed spring 14 causes the hammer to move at high speed and hit the base piece 5, Fig 2. Spring 20 returns the assembly back to its rest position and sloping edges 30 returns the lugs 11 into notches 12. In addition upon compression the element 22 pushes ring 34 to release gas from burner mouth 35. Cap 15 of assembly 2 is preferably axially displaceable thereon (Figs 23, 24). <IMAGE>

Title: Temperature responsive fluid fan coupling device
Inventor: INOUE HIROSHI
IPC: F16D35/02
Filed: 1993-03-01
Abstract: It is possible to more effectively reduce extraordinary noise of a fan and promote warm-up idling by restricting the occurrence of "corotation" on the fan side to a short period of time after the start of an engine. Similarly, in relation to a specified small amount of oil sealed in a compartmented receiving chamber, it is also possible to restrict the "corotation" of the fan remarkably effectively that would be caused when an abrupt transition is made from a low-speed operating state to a high-speed operating one by virtue of inlet and outlet in the receiving chamber, efficient pumping function in a dam and the construction of the receiving chamber, thereby making it possible to accelerate heat radiation effect. The thickness of a driving disc is made as thick over the whole surface on its peripheral side as confronts the darn, and the interior of the driving disc is formed into a receiving chamber having a radial wall protruding radially from the inner circumferential surface thereof. Furthermore, a small-diameter hole is formed between the radial walls at a position located slightly inwardly of the circumferential side surface of the back wall portion of the driving disc confronting an oil reservoir, and a through hole in the vicinity of the center of the front side wall of the driving disc. <IMAGE>

Title: An energy storage apparatus with an energy absorbing structure that limits torque in the event of a failure
Inventor: FULLWOOD DAVID TOD
IPC: H02K7/02
Filed: 1995-10-03
Abstract: An energy storage and conversion apparatus 1 has a cylindrical mantle 37 positioned between rotor 15 and containment wall 5. In the event of rotor failure producing fragments which are still rotating, the cylindrical mantle 37 acts as an energy absorbing structure by rotating on friction bearing pads 39,41, thereby limiting the torque transmitted to containment 5 and the machine mountings. The rotor 15 has a shaft 13 which is supported by a pin 25, of pin bearing 23, in an end cap 17. Rotor 15 is enclosed in a vacuum chamber 9 and is driven by stator 11 to store kinetic energy and acts with the stator 11 as a generator to produce electricity. If the end cap 17 disengages from the rotor 15 an end bearing 43 engages the rotor, after it has dropped, thereby absorbing its energy.
