Title: Powered respirators
Inventor: EDWARDS DAVID B
IPC: G01L9/00
Filed: 1989-06-23
Granted: 1992-09-15
Abstract: ABSTRACT OF THE DISCLOSURE            A powered respirator is provided with a device sensitive to the pressure within the respirator in the region of the user's face and adapted to sound a warning in the event that the sensed pressure goes below a selected threshold value.   The device includes a flexible diaphragm exposed on its opposite sides to the sensed and atmospheric pressures respectively, and an infra red emitter and receiver arranged so that the level of energy received by the receiver from the emitter depends upon the flexural position of the diaphragm.   In different embodiments the diaphragm may be arranged to reflect the radiation from the emitter onto the receiver or not, or to interrupt a beam of radiation from the emitter to the receiver or not, depending on the pressure differential across it.   In either case, when a sufficient energy level is detected at the receiver, indicating a pressure level below the selected threshold, power is switched to a sounder to warn the user of the low pressure condition.

Abstract: Copper(II) hydroxide is produced by a reaction of copper oxychloride in an aqueous suspension with alkali hydroxide or alkaline earth metal hydroxide in the presence of a stabilizing agent and the product is separated and washed. To improve the stability of the copper hydroxide and to avoid a black coloring by copper oxide, inorganic silicon compounds which contain hydroxyl groups (SiOH) in the molecules or form such groups in an aqueous medium are added to the suspension. It is desirable to use particulate solid silicic acids or silicic acids which are soluble in water or colloidally dissolved.

Abstract: The present invention relates to a method for producing a continuous web of material (36) on an endless belt (24). Fibres suspended in a carrier gas are transported from a transport conduit (12) through a transition part (38) of zig-zag configuration, having cross-section which tapers or narrows in the flow direction . Arranged at the outlet aperture of the transition part is a coarse-particle separator means (22) which incorporates a curved, convex surface (60), an accept outlet (48), and a reject outlet (54). The carrier gas is deflected around the convex surface, as a result of the ensuing Coanda-effect, and transports fine fibres to the accept outlet, while coarse particles, due to their greater kinetic energy, pass in a straighter path to the reject outlet (54). The accept outlet leads directly to a distribution chamber (52) which is located above the endless belt (24), and opposite which there is provided a suction box (32) for extraction of the carrier gas.

Inventor: AICHER MAX
IPC: B21B45/08
Filed: 1988-08-24
Abstract: To apply a coating of a non-ferrous metal such as, for example, zinc to the surface of rolled steel to increase the corrosion resistance, it is proposed to descale the rolled steel continuously downstream of the rolling step from the rolling pass by applying pressurised water and, immediately after descaling and while preventing a renewed formation of scale, to cool it by means of water rapidly to a temperature suitable for hot application of the coating and finally to apply the coating. One of the advantages of the invention is that, both for descaling and for preventing the renewed formation of scale and for simultaneous cooling, only a single medium, namely water, is used, and the cooling can be controlled in such a way that the rolling pass can be exploited in an optimised manner for the coating. The result is that all process steps or treatment processes can proceed as a continuous extension of the rolling step, i.e. at rolling speed, so that the finished coated end product leaves the production line analogously to a normal, not aftertreated rolled product.

Abstract: PCT No. PCT/NO92/00067 Sec. 371 Date Oct. 7, 1994 Sec. 102(e) Date Oct. 7, 1994 PCT Filed Apr. 10, 1992The patent claims concern a method for a more efficient "wet [combustion] oxidation" of COD-containing effluents from industrial processes and municipal plants and for a more efficient COD-reduction by enzymes in aerobic and anaerobic biological cleaning processes and for same sorts of effluents. The method implies a strong increase of the reaction speed between added oxygen and the elements in the liquid to be oxidized through so-called "Turbo Oxidation", which implies that the liquid is submitted to strong movements nd turbulence during several circulations within one or more liquid circuits during continuous addition of oxygen. By the same method, COD reduction by enzymes can also be made more effective. The single circuit is placed in connection to and communicates liquid-wise with a pressurized reaction tank, from where the developed reaction gases are continuously let out. Into the circuits and the attached reaction tank is continuously fed controlled quantities of the liquid to be oxidized together with proportionate quantities of oxygen or enzymes. Concurrently, the outlets of respectively oxidized liquid and evolved gases are controlled automatically. Out-going, oxidized liquid can be heat exchanged against in-going liquid, and the hot gases from the reaction tank can be used for external, heating purposes.

Title: Imaged symbol classification

Granted: 1995-10-24
Abstract: A highly effective OCR system that combines various techniques to remove meaningless variability and capture meaningful variability on the image before attempting to classify the characters within the image. Specifically, characters to be recognized are scanned to form a pixel image, and the image is scaled and "cleansed." The scaled and cleansed image is deskewed and skeletonized to form a thinned image, and the thinned image is applied to a neural network that extracts features of the image and forms an image map. Features are then combined to form "super features." Thereafter, the image is coarse blocked to reduce the dimensionality of the resulting feature vector. The feature vector is, lastly, applied to a classified that identifies the character.

Abstract: ABSTRACT OF THE DISCLOSURE     A conference speech-channel forming method and its conference  telephone  system,   in  which  an  extension telephone  set  to  be  operated  by  an  operator  as  the chairman of a conference is connected in a predetermined logical  manner through a private branch exchange to a plurality of extension telephone sets to be operated by a plurality  of  operators  as  the  participators  of  the conference  to  form  conference  speech  channels  between these extension telephone sets.  That is, the conference speech channels are formed so that  (a)  a voice signal issued from the extension telephone set of the chairman operator is parallelly transmitted in one way to all the plurality of extension telephone sets of the plurality of participator operators, and (b) voice signals issued from the  plurality  of  extension  telephone  sets  of  the participator operators are added together at a voice adder circuit and then transmitted to the extension telephone set  of  the  chairman  operator.   In this  case,  mutual speeches  between  the  chairman  and  participators  are allowed  only  in  a  one-to-plurality  relationship.   In addition, mutual speeches between the participators other than the chairman are restricted.  Thus, even in the event where  the number  of  participators  in a  conference  is large,  the chairman operator can smoothly expedite the proceedings of the conference.
