Title: Low noise photoreceiver
Inventor: LE HELLOCO GUY YVES MARIE
IPC: G01S7/48
Filed: 1980-04-09
Granted: 1985-05-09
Abstract: 1. Photoreceiver device for a narrow band useful signal, of the type comprising a photomultiplier transducer (10) associated with a controlled polarisation circuit (15, 16) which regulates the multiplier factor thereof, a main amplifier (11) connected between the output of the photomultiplier and the output terminal (12) of the photoreceiver device as well as a polarisation control chain connected between the output of the main amplifier (11) and the control input of the polarisation circuit, a device in which, - it being noted that the output terminal finally gives the useful signal, of level Ns , a noise multiplied by the transducer of level Nb  ; due to the ambient illumination as well as to inherent characteristics of the transducer and a noise not multiplied by the transducer, of level Nx , due solely to inherent characteristics of the transducer and of the main amplifier, these noise levels being assigned to the same width of reference band, - the control chain comprises : a level detector circuit (130, 131) connected to the output of the amplifier (11) for detecting the general output level there of Ns + Nb + Nx , an auxiliary signal generator (21) of predetermined level linked with a reference level K and a comparator (14) where of the two inputs respectively receive the output of the detector circuit (130, 131) and a signal drawn from the output of the auxiliary signal generator (21, 230, 231), where as its output controls the polarisation circuit (15), in order that the latter respects the relationship : Ns + Nb + Ns = K, characterized by the fact that : - the auxiliary signal generator (21) produces a signal (FR) where of the frequency band is separated from that of the useful signal of the transducer. - this signal is applied to the input of the main amplifier (11) with the output of the phototransducer, - the detector circuit comprises a band-cut filter (130) connected to the output of the main amplifier (11), eliminating the auxiliary signal and followed by a level detector stage (131), as well as a band-pass filter (230) connected to the output of the main amplifier (11), selecting the auxiliary signal and followed by a second level detector stage (231) and - the comparator (14) receives at its input the respective outputs of the two level detector stages (131, 231), so that : - when the level Ns of the useful signal is much less than the noise levels Nb  and Nx , the control condition is Nb + Nx = K, - when the level Ns  of the useful signal is of the same order as that of the noises, it being noted that the amplified noise is then negligible, the control operates with automatic gain control in order to keep the output signal of the photoreceiver device substantially constant, - where as when the level Ns  of the useful signal is much higher than the levels Nb  and Ns  of the noises, the polarisation circuit (15) produces a predetermined polarisation corresponding to a minimal multiplier factor.

Abstract: An incinerator system includes: a main chamber (32); double reburn tunnels (41,42); an excitor (134,158) within a reburn tunnel; a grate (234) near the incinerator's inlet (231) to permit the drying and initial combustion of refuse, and an ash scoop (278). The use of dual reburn tunnels (41,42), along with a damper (69,70) that permits the closure of at least one of them, permits the efficient and environmentally acceptable utilization of the main incinerator chamber (32) even with minimal refuse contained there. With less refuse, only one reburn unit (41,42) operates; it will still have sufficient heat and throughput to maintain, with minimal auxiliary fuel, the temperature needed for complete combustion. An excitor (134,158), or solid stationary object placed within the reburn tunnel (41,42), permits the retention and reflection of the heat generated by the burning to assure complete combustion of all hydrocarbons within the reburn unit. Additionally, the air utilized in the reburn unit may enter through the excitor for efficient distribution and concomitant combustion. <IMAGE>

Inventor: GORTSEMA FRANK PETER
IPC: B01J20/18
Filed: 1983-07-30
Granted: 1989-02-16
Abstract: Described herein is a process for enhancing the hydrophobicity of crystalline molecular sieves and also crystalline molecular sieve compositions which have enhanced hydrophobic character and modified catalytic properties. The crystalline molecular sieves are contacted with a silicon tetrafluoride gas mixture at a temperature from about ambient to about 200 DEG C to alter (1) the framework aluminum and silica content, (2) the surface characteristics, and (3) the acidic sites of the molecular sieves with resulting modification of both the adsorptive properties, i.e., enhanced hydrophobicity, and catalytic properties of the molecular sieves. The crystalline molecular sieves can further undergo ion exchange to remove any aluminum fluoride cation species such as AIF<+><+> and AIF2<+>. The crystalline molecular sieve compositions of this invention are useful as selective hydrophobic adsorbents and catalysts.

Inventor: POST WILLEM PIETER
IPC: B21D51/26
Filed: 1984-06-06
Granted: 1987-10-29
Abstract: In the wall of the tin body grooves are introduced between tools radially movable in opposite senses towards the tin body, one tool being provided with ridges and the other with grooves registering with the ridges. This method makes it possible, contrary to the usual rollers, to introduce grooves with fairly small tolerances. Damage of the lacquer does not occur. Because of the forming of sharper grooves the radial strength will be improved and the wall thickness of the tin body can be reduced.
