Title: Prodn. of calcium tartrate from hot soln. of wine dregs etc. - by sepg. pptd. tartrate from organic sediment in elutriation leg
IPC: C12F3/10
Filed: 1981-09-18
Abstract: A process and an installation for the prodn. of calcium tartrate from a hot soln. of residual marc extract, wine dregs etc. contg. potassium bitartrate. The soln. is mixed with an aq. slurry of calcium cpds. to convert the bitartrate into tartrate of calcium, thereby eliminating tartrates from the soln. The calcium tartrate is pptd. into an elutriation leg in the base of a processing vessel in which the mixt. is treated. The ppte. is extracted, washed and dried. The wash water, together with mother-liquor drawn off at the top of the vessel, is reinjected at the base of the vessel below the accumulating precipitate. This rising current entrains organic sediments and return them to the upper part of the vessel. Pref. the headspace of the vessel is connected to a vacuum pump which reduces pressure in the vessel. This produces adiabatic expansion and partial evapn. of the water and cools the mixt. in the vessel. The process eliminates disadvantages associated with previous systems, viz: costly sepg. cyclones, and cooling with added water which increases the volume of effluent to be handled.

Title: Optical receiver
IPC: H04B10/69
Filed: 1982-07-07
Abstract: An optical receiver for responding to optical energy propagating in an optical fibre transmissions path (1) is detected by a reverse-biassed p-i-n diode (2) which is in series with a forward-biassed p-i-n diode (3). The junction between the two diodes is connected to the input of an amplifier (4), which feeds on auto-equalizer. The auto-equalizer includes another p-i-n diode (7) which is in series with the signal path, and is forward-biassed. Due to the associated components including resistors (9,10), the diode (7) passes the same average current as do the diodes (2,3) at the front end of the receiver. The overall effect of the third diode (7) is to provide the receiver with a substantial region in its characteristic whose frequency response is flat.

Patent ES-8405947-A1 (ES)
Title: Method and apparatus for comparing data signals in a container inspection device
IPC: B65B57/02
Filed: 1983-09-13
Abstract: The present invention relates to an apparatus and method for generating a comparison signal representing the deviation between two analog video signals representing light received from particular inspection points on an object being inspected. The comparison signal is generated with a magnitude representing the ratio between the values of the two video signals. The ratio is calculated with the one of the two video signals having the larger magnitude as the denominator. In order to calculate the ratio, the present invention first converts the two analog video signals to digital form and then determines the log of each of digitized video signal. Next, the negative difference between the two log signals is determined. The negative difference is then exponentiated to determine the ratio.

Title: Manufacture of plastic silencer for sealed type electrically driven compressor
IPC: B29C65/10
Filed: 1983-09-30
Abstract: PURPOSE:To improve airtightness and reliability by forming a gap part on a butt-joint outside surface beforehand and melting and fusing, by the hot wind in non-contact type, the projected edge of a flange part which projects outside in the state closely fitted by a pressed pressure. CONSTITUTION:Flange parts 11-1 and 11-2 which project outside are formed on the butt-joint parts of silencer bodies 7-1 and 7-2, and each thickness of the flange parts 11-1 and 11-2 is made smaller than that of silencer parts 7-2a and 7-2b, and a gap is formed between the flange parts 11-1 and 11-2, and the flange parts are pressed and closely attached by a pressing jig 15, and the projected edges of the flange parts are molten and fused over the whole periphery by the hot wind in non-contact type. Therefore, a pressing force always acts onto the inside butt-joint surface of a coolant flow passage, and the seal performance of the inside butt-joint part is improved by said pressing force, and thus airtightness and reliability can be improved.

Patent ES-8507233-A1 (ES)
Title: A pressure transducer.
IPC: G01L7/16
Filed: 1984-03-02
Abstract: A differential pressure gauge 10 utilizes a piston member 18 provided with a series of grooves 19 right around it, so that the piston member 18 itself forms the rack of a rack-and-pinion device (pinion 22) for converting linear displacement of the piston member into rotary displacement of the pinion. For sensitivity and accuracy, the seal between the piston member 18 and the passage 13 is a hard-surface-to-hard-surface engagement between substantial (total) hard surface areas at any one time of the passage 13 and the piston member 18, including regions of the surface area of the piston member 18 intermediate mutually adjacent end ones of the grooves 19. In this way, the gauge is insensitive to the base pressure, there being no soft seals to deform under pressure. A magnetic coupling is used through the wall of the housing, which can thus be made completely pressure-tight. One embodiment indicates a reverse differential pressure by allowing the piston to travel beyond the normal end position upon overcoming the preload of a second spring.
