Title: Negative impedance repeater for telephone lines
IPC: H03H11/44
Filed: 1974-01-15
Abstract: A negative impedance repeater for amplification in telephone lines operating at voice frequency comprises two converters, one of them stable with open terminals and the other stable with short-circuited terminals each converter is loaded by a fixed network of passive impedances chosen according to the characteristic impedance of the line to be amplified, and provided with means, external to the network of passive impedances, for adjusting the feedback, and consequently the conversion ratio. The conversion ratios of the two converters may be varied independently from each other so that in the case of loaded lines their product may be kept always constant and this allows to adjust the repeater gain without modifying its impedance, while for unloaded lines it is possible to obtain that such product increases with a certain law by increasing gain, and this fact causes an equalization at the highest frequencies of the band, which is necessary for this type of lines.

Title: Clip terminal and applicator tool combination
IPC: H01R4/24
Filed: 1974-06-05
Abstract: The embodiment of the invention disclosed herein is directed to a clip terminal and applicator tool combination which allows rapid application of a plurality of insulated wires to clip terminals formed on terminal strips used for electrical connection to removable printed circuit boards or the like. The clip terminal has a notch formed at the upper end thereof and an aperture spaced below the notch, the notch and aperture are communicated with one another by means of a slot formed therebetween. The notch includes relatively sharp corner edges immediately preceding the slot. When an insulated conductor is laid over the clip terminal in registry with the notch, an applicator tool is used smartly to urge the insulated wire through the slot, thereby causing the sharp corner edges to strip the insulation from the conductor and bare the wire. The bare portion of the conductor makes electrical contact with the clip terminal. Upon further pressure applied to the applicator tool a cutting device is actuated and cuts the end portion of the conductor. When clip terminals are positioned in transverse pairs the cutting tool separates a single conductor to allow individual paired connections to be made simultaneously.

Title: Breaking chamber for self-blasting compressed gas electric circuit-breakers
IPC: H01H33/915
Filed: 1974-06-12
Abstract: An axial blast breaking chamber for self-blasting compressed gas electric circuit breakers wherein the chamber wall is provided with sets of upstream and downstream radial holes having entrances to the inside of the breaker chamber through respective ring-like feeding grooves coaxial to the longitudinal axis of the chamber. When the circuit breaker contacts are closed, the fixed contact, which is in close proximity to the inner wall of the chamber, extends past the feeding grooves thereby inhibiting flow of quenching gas. Flow of quenching gas remains inhibited until the chamber and attached movable contact are displaced sufficiently to withdraw the feeding groove and upstream set of radial holes below the lower end of the fixed contact. The flow is appreciably increased after the downstream set of radial holes is uncovered and interruption of the arc completed as the chamber and movable contact are further separated from the fixed contact.

Title: Hide processing machine and method
IPC: C14C15/00
Filed: 1978-06-22
Abstract: An improved hide processing machine has a hide-treating drum supported for rotation about a central longitudinal axis to retain and tumble hides and treating fluids at a closed end of the drum.

Title: Method of producing microbubbles for treating a suspension
IPC: B03D1/14
Filed: 1978-07-26
Abstract: A method of producing bubbles for treating a suspension by flotation, wherein in which the suspension enriched with dissolved gas is caused to flow into a flotation vat via a pipe the flow in the pipe is rapidly interrupted at a predetermined frequency by a shutter unit which is suddenly closed and produces, in the downstream portion of the pipe, a periodic wave of low pressure such that cavitation bubbles are produced in the flow in said downstream portion, the low pressure wave propagating in the pipe up to the flotation vat where it is reflected as a wave of high pressure which produces the collapse of the cavitation bubbles and forms micro-bubbles which become fixed to the particles to be floated, the conditions in the pipe being such that the micro-bubbles are in a super-saturated medium in relation to the local pressure conditions and tend to be enlarged during their flow up to the flotation vat.

Title: Process for inspecting the physical state of a printed document and an installation for putting the process into operation
IPC: G07D7/187
Filed: 1979-11-30
Abstract: Documents are caused to pass in front of a light source incorporating optical fibres and the reflected light is collected by means of photoelectric elements. The collected reflected light is compared with a reference value. A row of photoelectric elements is used which successively transmits, by multiplexing, the signals delivered simultaneously by a row of the photoelectric elements. The analog signals are converted into digital signals, and a totalling and averaging of the digital signals is carried out in order to determine the state of general dirtiness of the document. The number of photoelectric elements of the row covered by the document is counted to inspect the width of the document and detect the presence of dog ears. In addition the number of photoelectric elements delivering a signal which exceeds a certain level is counted. Finally each digital signal corresponding to a point of the document is compared with a reference value in order to determine the presence of a hole, a stain or similar condition. The comparisons and tests are carried out by processing logic. The installation includes means for virtually displacing the reading head taking into account the real lateral displacement of the document in relation to the row of diodes.

Patent ES-8106680-A1 (ES)
Title: Process and apparatus for the biological treatment of aqueous waste in a pure oxygen-activated sludge/ozone system.
IPC: C02F1/78
Filed: 1980-09-11
Abstract: A process is provided for the biological treatment of aqueous waste in a pure oxygen activated sludge/ozone disinfection system as well as apparatus to accomplish the process. In this process, the off-gas from an ozone disinfection tank, after removal of residual ozone, is blended with the pure oxygen stream needed to supply the requirements of activated sludge treatment basin and ozonation zone. This blending of two streams is carried out either in pipe line or in a specially built (and baffled) vessel. The combined stream is then compressed and split into two portions. One portion of the gas is diverted to the activated sludge treatment plant. The rest of the gas is dried to a dew point level and then fed to ozone generator. The discharge from the ozone generator contains a small percentage of ozone and is routed to the ozone disinfection tank. An alternate of the system, compresses the off-gas first and then combines it with pure oxygen stream. A two bed desiccant type dryer should preferably be employed for the drying of the gas stream upstream of the ozone generator. A required amount of pure oxygen will be used to purge the inactive bed of the dryer. The wastewater first flows into an oxygenation basin, whereby through the action of microorganisms in the presence of an oxygen rich gas, the organics in the wastewater are converted (oxidized) into harmless compounds. The wastewater is discharged into a settling basin, where the biomass settles to form activated sludge which is returned to the oxygenation basin. The clarified liquid from the settling basin overflows into an ozone contact tank where the ozonated gas is introduced to disinfect the water stream.
