Title: Electrode structure for particle accelerator - has principle electrode and surrounding reference potential body with intermediate ring and bar electrode structure
Inventor: LETOURNEL MICHEL
IPC: H05H5/04
Filed: 1981-01-15
Abstract: The particle accelerator, has a high tension principal electrode (EP) spaced from a symmetrical body (T) around the electrode and forming a reference potential. A discrete auxiliary electrode structure (DA,DB,DL) is formed by ring electrodes (DA) and bar electrodes (DB,DL) mounted about the principal electrode and acting to alter the lines of electric field to render them, at least in part, parallel. This reduces the spacing between the principal electrode and the body. An axial stack of secondary electrodes (S1,etc.), comprising equipotential rings or plates interconnected by resistances to form a potential divider, is provided between the principal electrode and reference potential.

Title: Blood pressure measuring appts. - has differentiator supplying timing pulse shaper and integrator feeding discriminator
Inventor: ERSHOVA T I
IPC: A61B5/022
Filed: 1981-01-16
Abstract: The arterial blood pressure is measured by applying to the arm of a patient a bandage and by producing tacho-oscillations as time derivatives of the pulse oscillations. Their positive and negative half-waves are integrated to produce an information signal and the supplied pressure is measured when this signal reaches a max. and half the max. This produces the average systolic and diastolic blood pressure values. The bandage (1) is pneumatically connected to a pressure measuring device (2) with a pressure pick-up (4) and a pulse fluctuation pick-up (5) which are equipped with a differentiating facility (24). One pick-up (4) is connected in series with a pressure memory (11), a commutator (17) and a recorder (23) to indicate the arterial pressure. The differentiator (24) supplies a timing pulse shaper (26) which controls the memory (11), as well as an integrator (29), controlled by the same shaper (26). The integrator output is fed to a discriminator (34) for the max. of the information signal, to a scale-of-two divider (40), a memory (43) for half this max. and a comparator (37). The comparator output is also passed to the control input (44) of the memory (43) and to a controller (8) which sets the conditions for the device (2) and memory (11). This produces accurate and reliable results.

Title: Very high revolution rate flywheel energy store - with rotor discs made of titanium alloy with carbon fibre material binding
Inventor: WIEDEMANN HANS
IPC: H02K7/02
Filed: 1981-07-08
Abstract: The metal body (1) of the rotor, consists of a shaft carrying one or more circular sections, in which, distributed equally around the same internal radius (e) are a number of cylindrical permanent magnets (2) pressed or otherwise fixed in holes (1a) to suit their diameter. The metal body is pref. of titanium alloy, bound with a fibre or thread material, with a modulus of elasticity of twice that of the titanium e.g. carbon on boron fibre. The binding (3) is laminated with epoxy resin and prevents the fracture of the outer ring of the disc due to the stress imposed by the rotating mass of the magnets (2). Thus the flywheel energy store is an extremely fast-rotating synchronous rotor with axial or radial magnets housed in a rotating body, producing axial or radial magnetic energy.

Title: Aerial for EM radiation of plants and animals - comprises metal collar with inductive and capacitive elements included in structure to allow oscillation at gap of preset width
IPC: A01K27/00
Filed: 1981-08-21
Abstract: The aerial includes a length of conductor (C) which may for example consist of three strands of enamelled copper wire. The wire is bent into an approximately circular loop, with the free ends overlapping by about 3 cm. The ends of the wire are thus very close to each other, but not actually in electrical contact, forming a capacitor. They may be glued together in order to maintain constant relative position. On the opposite side of the wire loop there may be a few smaller dia. turns in the wire forming an inductance (IN). Together, the inductance and capacitance of the wire may thus form a resonant oscillating circuit. The wire may then be used to irradiate plants or animals with high frequency electromagnetic radiation.

Pref. the outer face of the oblique rib is angled at about 30 degrees to the axis of the cap, and its inner face at 45 degrees. These inclined surfaces do not appear to intersect but to be joined by a narrow crest parallel to the cap axis.
Patent FR-2500186-A1 (FR)
Inventor: HUNTER EDWIN J
IPC: G05D16/10
Filed: 1982-02-03
Abstract: Pressure control valve with an inlet channel (22, 122) and an outlet channel (24, 124) arranged downstream of the inlet channel and with a valve seat (45, 145) arranged between the inlet channel and the outlet channel and having a valve-closing arrangement (47, 147) which is balanced relative to the inlet pressure and moves between an open and a closed position with respect to the valve seat only as a function of the outlet pressure. The valve-closing arrangement comprises a valve plate (48, 148) with an upstream face (50, 150) exposed to the inlet pressure and a downstream face (52, 152) exposed to the outlet pressure, the downstream face striking against the valve seat when the valve-closing arrangement is in the closed position. The valve plate is connected to a flexible diaphragm (38, 138). The closing arrangement is prestressed in the direction of the open position with a certain force, as a result of which the upstream face strikes against the valve seat when the outlet pressure on the downstream face exceeds a certain value. It is therefore impossible for the pressure in the outlet channel to exceed the predetermined force with which the arrangement is prestressed.
