Title: Y-section roofing beam - uses section of ordinary reinforced concrete to connect two prestressed reinforced concrete longerons
Inventor: FALSINI LUIGI
IPC: E04B7/08
Filed: 1980-06-18
Abstract: The roofing beam of Y-section and non-uniform height is made up of upper (1) and lower (3) sections of prestressed reinforced concrete connected by sections (5) of ordinary reinforced concrete, the beam being cast in one piece. The ends of the beam (6) are filled in to allow variation in beam length at the time of casting.

Title: Spectacle mounted audio amplifier for hearing aid - has wire connecting side arm circuits in groove between frame and lens junction
IPC: G02C11/06
Filed: 1980-07-04
Abstract: The spectacles include a circuit for receiving, amplifying and transmitting sound to the user's ear, the parts of the circuit being located in the two arms of the spectacles are interconnected by a wire which is slotted into a groove in the lens holders between the frame and the lenses. The groove connects with the side arms through small holes formed in the frame adjacent the arms. The groove is formed by the junction of the planar edges of the lenses with the V-shaped inner edges of the lens holder portions of the frame. The location of the wire is such that a groove enables the mass of the frame to be kept low to retain the aesthetic qualities of the frame without reducing its strength.

Title: Pulse compression coded radar receiver - has variable gain receiver applying weighting coefficients to reduce auto-correlation secondary lobes
Inventor: DALBERA MICHEL RENE JOSEPH
IPC: G01S13/28
Filed: 1980-08-20
Abstract: The radar signal processing circuit reduces the autocorrelation secondary lobes. The pulse compression radar emits pulses of modulated length, the modulation being according to a binary code using m sub-pulses. A variable gain circuit receives the signal along with a replica of the emitted signal. For each distance gate in the receiver, a weighting circuit operates so that on the arrival of the mth pulse, correlation is carried out on m sub-pulses of equal amplitude. The weighting stage (4,5) comprises multiplication circuits, multiplying the sub-pulses of the examined signal by a series of correlation coefficients (Cni) to compensate for the effect of the gain varying with distance. The set of coefficients are functions of n, the range of the distance gage, and i, the number of the sub-pulse.

Title: Enhanced oil recovery by injection of carbon di:oxide - and aq. wetting agent, both preceded by aq. foaming agent
Inventor: BALINT VALER
IPC: C09K8/594
Filed: 1980-11-28
Abstract: A process for enhanced recovery of oil from a reservoir, using the injection of CO2 or similar gas, comprises the following steps. (i) An aq. soln.of a synthetic foaming agent is injected at an injection well. If the formation has a gas cap, this injection is made at its boundary, giving a foam curtain to prevent penetration of foam into the cap. (ii) CO2 or other gas is injected to displace the oil, with an aq. soln. of wetting agent to counter the tendency of asphaltenes sepd. out by the CO2 to deposit on the pore walls. (iii) Water, opt. satd. with CO2, is injected. Used esp. in formations of varying permeability. CO2 is not wasted by filling the gas cap. By the action of foaming and wetting agents, the vol. of oil removed per unit vol. injected is increased, as is the displacement of oil on the micro scale.

Title: Low power consumption monostable relay - has ON=OFF switch coupled to bistable relay by capacitor connected transistor pulse generator
Inventor: HOLVOET-VERMAUT GERARD
IPC: H01H47/22
Filed: 1981-01-23
Abstract: The relay has an on/off switch (30) connecting a battery (20) to a pulse generator (31) in turn coupled to a bistable relay (32).

Title: Magnetically controlled electric keyboard - has key-operated magnetic pallets inducing e.m.f. in underlying sheet of conductors
Inventor: ROCHE GEORGES
IPC: H03K17/972
Filed: 1981-12-15
Abstract: The keys act on magnetic pallets (3) which are disposed above a multipolar magnetic plate (5) covered by at least one inductive sheet (6) of conductors (2).There is a plate (7) of non-remanent magnetic material on the under side of the multipolar magnetic plate. The magnetic pallets, which are also of non-remanent magnetic material, each have a manipulating arm (8) at an oblique angle to the pellet and originating from one of its edges. This edge forms an axis of rotation (9) parallel to the magnetised plate on which it is supported. The pallet can therefore move from a rest position when it is held magnetically against the magnetised plate to an open position in which it is obliquely disposed w.r.t. the magnetised plate by the action of its associated key. The magnetic pallets are therefore used to create an electromotive force by electromagnetic induction in the conductors placed under the moving pallets.
