Patent FR-2298458-A1 (FR)
IPC: B60T15/52
Filed: 1976-01-20
Abstract: The control piston (3) to be actuated by the servopressure to be boosted is pivoted close to the end of a balance beam (12) variably supported as a function of the vehicle load, whilst, acting counter to the control piston (3), the return piston (4) actuated by the boosted brake pressure is pivoted on the other end of the balance beam (12). That end of the balance beam (12) close to the control piston (3) acts on a brake valve device (24). In order to prevent the vehicle load-related support of the balance beam (12) from influencing the minimum brake pressure setting, the beam is formed from a spring (14) of the abutment (16) acting counter to the direction of actuation of the return piston (4), the spring force being approximately equal to the force exerted by the return piston (4) when actuated by a minimum brake pressure sufficient for application of the brake.

Title: Continuous proportioning of components of mixture - uses computer monitoring variations in weight of supply bins and comparing with programmed weights
IPC: G05D11/13
Filed: 1976-05-13
Abstract: The mixture proportioning method uses a computer (X) to compare weights of the mixtures constituents. The weight of the constituent is determined by a comparison with data furnished by a programme. This programme gives the variation law fixed for the particular comparison. Any variation detected is amplified to control the flow regulation of the mixts. constituents to arrive at the desired mixt. composition. The comparison between each weighed constituent of the mixt. and the weight corresp. to the programme is obtained during short time intervals. The system has a series of bins (A, B, C) contg. the constituents. It has means for monitoring the weight of each of the bins.

Title: Automatic precise measurement of hydrocarbon content of aq. effluent - takes hydrocarbons into soln. for infrared spectrophotometry
Inventor: GUIGUES FREDERIC
IPC: G01N33/18
Filed: 1976-05-14
Abstract: The appts. takes a fixed vol. sample of effluent, dissolves any hydrocarbon of the sample in a known vol. of CCl4 and then uses a spectrophotometer to measure the absorption of IR energy by the soln. Each sample of the series taken from the effluent supply is directed into a mechanical mixing vessel together with a dose of CCl4 and any selected reagent. The contents of the vessel are delivered through a decanting unit to separate CCl4 soln. from the remaining effluent. The soln. is filtered and then passed through a spectrophotometer which drains into a soln. receiver. All stages of sample extn. and measurement, dosing, mixing, decanting, sepg., filtering and spectrophotometry pref. follow a sequence automatically determined by a programmed controller. Used for automatically taking regular samples from an effluent supply and checking each sample hydrocarbons content which is measured with great precision, partic. to give warning if a sample contains hydrocarbons at a level above an acceptable limit, usually 20 p.p.m.

Title: Lubrication of drill bit for use in borehole drilling - by prior degassing of lubricant itself and lubricant passages and spaces in the drill bit
Inventor: GALLE EDWARD MILBURN
IPC: F16N37/00
Filed: 1976-05-26
Abstract: The process comprises (i)assembling in sealed manner a rotary milling tool on the shaft of the drill bit so as to include passages and spaces for the lubricant, (ii) evacuating air and gas from these passages and spaces and then filling them with a lubricant, (iii) sealing the lubricant in the passages and spaces and limiting the potential lubricant pressure to a value selected in proportion to the hydrostatic pressure. Pref. the lubricant is also degassed by evacuation before being introduced into the passages and spaces in the drill bit. The presence of air or gas occluded or trapped in the passages and spaces of the drill bit interferes with the lubricating system. This is prevented by the prior evacuation of such air or gases both from the drill bit and from the lubricant itself.

Title: Reaction wheel waste water spray for percolating filter bed - sprays two concentric beds from different sources of liq.
IPC: C02F3/04
Filed: 1976-09-08
Abstract: Reaction wheel has radial spray arms which rotate the wheel in a horizontal plane to distribute waste water for treatment on to a circular percolating filter bed. The wheel has two coaxial sets of spray arms supplied from two different sources. One set of arms radiates from a rotary, hollow hub which sleeves, and is supplied with liq. by a fixed vertical centre pipe. The other set of arms radiates from, and is supplied with liq. by an annular rotary jacket fitted coaxially around the hub. The wheel assembly is fitted via a rotary seal, on top of a fixed support box through which liq. is supplied to the rotary jacket. The two sets of arms can rotate independently or integrally depending on whether the jacket is rotatable about or fixed to the hub. The wheel can spray two concentric filter beds simultaneously or independently with liqs. drawn from the separate sources. The wheel has the reliability and robustness of conventional reaction wheel sprays but saves installation space by using concentric filter beds rather than two circular beds alongside each other.

Title: Aircraft cabin pressure regulator - utilises regulator valve controlled by step motor from sensor inputs
Inventor: BOUTTEVILLE RAYMOND
IPC: G05D16/20
Filed: 1977-10-12
Abstract: The pressure in an aircraft cabin is regulated to prevent passengers being subjected to too low a pressure and to high speed pressure variations. This is performed by regulator valve controlled by step motor from sensor inputs. Pressure in aircraft cabin (10) is sensed (14) and processed (15) to produce an error signal which is converted (16) to frequency. This signal is applied to a modulator (18) which controls a step motor (17) which in turn controls a valve (13) in cabin air exhaust as inlet (11) air is supplied from a compressor. Manual control is provided via an oscillator (19) and modulator (20) circuit.
