Title: Logarithmic loop antenna arrangement for high frequency radio communication
Inventor: BROWN IAN DAVID
IPC: H01Q21/08
Filed: 1990-08-01
Abstract: An antenna for high frequency radio communication comprises an array of horizontally extending loop elements (113-117), each loop being of a substantially different length from the others and suspended above the ground (105) at a constant electrical height proportional to its resonant frequency. The loops are spaced vertically one above the other in a log periodic manner so as to define an inverted pyramid shape with its vertex at or near ground level. The loops are connected in parallel to a twin transmission line (119, 120) whose lines are crossed between successive elements so that the phase is reversed at each connection relative to the adjacent elements. Signal feed to the array is from the small end. Assuming there is no feeder-to-ground connection, transmission of the signal occurs vertically upwards from the element of elements having a resonant frequency nearest to the frequency of the input signal. The beam has substantially the same width at all frequencies, thus giving constant ionospheric illumination and therefor a constant radius of reception of the reflected transmissions on the ground around the antenna, provided that the frequency of the transmission is less than the ionospheric critical frequency. <IMAGE>

Title: Method of extracting dinitrogen pentoxide from its mixture with nitric acid
Inventor: BAGG GREVILLE EUAN GORDON
IPC: C01B21/20
Filed: 1992-03-16
Abstract: Method of extracting dinitrogen pentoxide (N2O5) from its mixture in nitric acid, which consists of providing a solution of the mixture in an inert organic solvent, stripping out the N2O5 from solution in a carrier gas stream containing ozone, and subsequently condensing the N2O5 out of the gas stream by contact with further inert organic solvent. The presence of ozone suppresses the dissociation of the N2O5 transferred to the gas stream into dinitrogen tetroxide (N2O4). In a preferred embodiment the stripping and absorbing steps take place continuously in adjacent stripping and absorbing columns respectively having organic solvent recirculating through each.
Patent GB-2252869-A (GB)
Title: Method for manufacturing electrostrictive effect element
Inventor: SOMEJI TAKAHIRO
IPC: H01L41/293
Filed: 1992-03-23
Abstract: Conventionally, electrostrictive effect elements have been obtained as follows. A laminated body in which every other internal electrodes are connected alternately with one of two external electrodes which are formed on opposed faces of the body, is set in a plating bath. Metal ions in the bath are deposited on the internal electrodes. After insulating films are formed, the insulating material only on the deposited metals are removed until the deposited metals are exposed, and the laminated body is cut. However, there are the problems, for example, the electrical conduction is not attained because of the oxidation of the deposited metals when the element is left at a high temperature. The solutions of the problems are found in this invention. Electrostrictive effect layers and internal electrodes are laminated alternately. The end faces of the every other internal electrodes are exposed on the opposed side faces respectively. Temporary external electrodes are formed on the exposed end faces of the internal electrodes. Metallic protrusions are formed on the end faces of the exposed internal electrodes by the electric plating using the temporary external electrodes as cathodes. Then, by mechanical machining or the like, the parts between the metallic protrusions (the parts being not plated) are removed to form recessed parts. Thereafter, insulating films are formed in the recessed parts. Then, by removing the insulating films through polishing to the depth until the metallic protruding parts are eliminated, the every other internal electrodes are made to be exposed or the metallic protruding parts are made to be exposed. In those places, external electrodes are formed, and the every other internal electrodes can be connected to the external electrodes. According to this invention, since the interfacial distances between the end parts of the internal electrodes having different potentials can be increased substantially, electrostrictive elements of high insulation reliability can be realized.

Title: Hydrostatic radial pocket bearing for a servo cylinder
Inventor: EIGENBROD KARL-HEINZ
IPC: F16C32/06
Filed: 1992-04-24
Abstract: A hydrostatic radial pocket bearing for a servo cylinder comprises an even number of bearing pockets 34 uniformly distributed over the bearing periphery and fed from a source 24 of pressure fluid by way of associated preliminary throttles connected to pressure supply conduits 22. The preliminary throttles are formed by the area 46 of the bearing gap situated between a supply orifice 48 and at least one outlet groove 44 which is in turn connected to an opposite bearing pocket, the bearing pocket being in the form of a re-entrant depression either in the fixed or in the moving bearing portion. To reduce loss energy caused by leakage and at the same time increase the force carrying capacity of the bearing, the pressure drop of the pressure fluid flow axially away from the bearing pocket is different on both sides 54, 56 by virtue of the differing dimensions A, BA. Alternatively, the fluid flow can discharge to two cylinder pressure chambers which operate at different pressures. <IMAGE>

Title: Device for parting and successively feeding stacked elements of sheet material to a user machine
Inventor: BORIANI SILVANO
IPC: B65H3/60
Filed: 1993-01-29
Abstract: A pile holder has opposite walls 12 and 13 which are joined by pivoted links 15 to enable wall 13 to be moved relative to wall 12 by means 21. In the figure 2 position, the pile of sheets 2 is loaded into the holder. Wall 13 is then moved to its figure 3 position, thus reducing the width of the holder and causing the individual sheets to slide over each other to become slightly shingled. This relative sliding causes separation of edges of adjacent sheets which might cling together, eg in the case of die-cut labels. An oscillating suction belt 39 then separates sheets from the pile. There may be two pile holders, one being loaded while separation from the other is effected. <IMAGE>

Title: Electrostatic discharge protection circuit for integrated circuits
Inventor: METZ LARRY S
IPC: H02H9/04
Filed: 1993-06-11
Abstract: The protection circuit has an SCR structure 10 connected between ground and an input/output pad 15 of the IC 16 and actively triggered by an FET 18, and means responsive to an ESD event at pad 15 to apply a trigger voltage to the gate of FET 18 so as to activate SCR 10 independently of a junction breakdown of FET 18. The means to trigger FET 18 may be an inverter 30, or a capacitor (40), (Fig 4a), powered by the ESD event. The FET 18 may be on the same substrate as SCR 10 or separate therefrom. A further FET (42), (Fig. 4a), may be provided to ground the gate of FET 18 when the supply voltage VDD is being applied to IC 16. The SCR 10 may have a well resistance Rw so that when FET 18 turns on current flow through resistance Rw creates a voltage drop thereacross large enough to turn on the SCR 10. The well resistance Rw may be replaced by parallel PFET and NFET devices (50), (Figs 5a, 6a), which inhibit forward biasing of the SCR when power (VDD) is being applied to IC 16 but allow forward biasing when power is not being applied to IC 16. <IMAGE>

Filed: 1993-08-26
Abstract: In a gas generator a first vessel (1) having a side wall, and an end closure (2) contains a mixture of helium and oxygen under high pressure of approximately 200 bar and a second vessel (21) contains hydrogen at a pressure of approximately 30 bar. A triggering mechanism is provided which, when activated, enables gas from both vessels to flow to a catalytic combustion zone (25). The combustion zone and flow-path to the airbag inlet is of non-decreasing cross-sectional area. In the preferred embodiment the combustion zone (25) is of annular form at the outlet of the annular outer periphery of the chamber. Thus the outlet is at the region of greatest cross-sectional area. As the gases combust there is no restriction and consequently no pressure rise during combustion obviating any risk of explosion. <IMAGE>
