Title: Process for isolating acrylic acid from an aqueous crude acrylic acid
Inventor: SENNEWALD KURT
IPC: C07C51/48
Filed: 1969-10-29
Abstract: 1,235,634. Acrylic acid. KNAPSACK A.G. 29 Oct., 1969 [29 Oct., 1968], No. 52973/69. Heading C2C. Pure acrylic acid is obtained from aqueous crude by extracting with 3,3,5-trimethylcyclohexanone and/or isophorone, water-washing the organic extract, dehydrating the extract in a first distilling zone, and distilling the base product therefrom in a second distilling zone to obtain the pure acrylic acid. The extracting and water washing may be simultaneous and by countercurrent. The aqueous phase from the extraction may be further distilled, the solvent separated as an azeotrope and recycled. Examples describe the use of a pulsation column in the extraction. Stabilizers, e.g. methylene blue, may be present.

A traversible apparatus for cleaning a felt in a paper-making machine includes a number of elements each rotatably mounted and each having a felt-contacting surface comprising interconnected crests and troughs the crest of greatest diameter being at or near the middle of the element and the diameters of the other crests decreasing progressively towards the ends of the element, and a number of devices to apply a contaminant-removing fluid to the felt as it passes over the elements. As shown, there are five elements 36, 37 &c., e.g. of nylon, each comprising a cylinder with a helical rib 38, 39 &c., alternately of opposite sense, each helical rib having its greatest diameter at the middle of its element, and decreasing towards each end. prayers 33, 34 &c., apply a cleaning liquid, e.g. a detergent or water, to the felt where it is stretched by the helical ribs. The "saturator" 35 is bowed upwards to correspond with the ribs 38 and 39, and has slots 41 through which cleaning fluid is supplied to the felt. All these and bars 15 are mounted on the open side of an otherwise closed box, which is connected to a source of vacuum. The box may be divided in two parts at 16, 17, which may be mounted on either side of another part of the papermachine, e.g. a roller (Fig. 5, not shown).

Abstract: 1460659 Data carrier and reader GREY LAB ESTABLISHMENT 18 Dec 1974 [28 Dec 1973] 54665/74 Heading G4M A data carrier e.g. a card carries parallel strips of electrically conductive material 13 to define, between adjacent pairs of strips, columns S0- S3. At selected positions in the columns e.g. at the junctions of rows Z1-Z8 are situated elements 14. To store permanent data selected ones of the elements are removed. The elements may be photoresistors, elastic electrically conductive material, capacitors, Hall effect material, inductances, field effect transistors or field sensitive diodes, temperature sensitive resistors, relays or other material having an electrically measurable characteristic which can be altered by externally applied means i.e. by applying light, heat, electric or magnetic fields or pressure. A further section B of the carrier contains the same or different elements at each cross-over point and is provided with a cover of material impervious to the external means and having windows 16 through which selected elements only can be altered. A reader for the carrier (Fig. 11) receives the carrier through a slot 40 and has member 41 receiving an end of the element. Member 41 is connected to an endless belt 42 moved by motor 44. When the carrier is inserted spring loaded electrodes 45 read a recognition line on the carrier to determine if a correct carrier is being read. The card is moved if valid data is detected and, in this embodiment, magnets 48 alter the characteristics of Hall effect devices so that data can be measured. One of the colums may contain a clock track.

In a closable air intake for an aircraft engine having a guard grid to prevent the sucking in of debris through the air intake orifice, the guard grid is movable between an operation and an inoperative position and is connected to an air intake closing device so as to be necessarily moved into the operative position as soon as the air intake orifice is uncovered. The guard grid 60, Fig. 4, of the gas generator of a lift engine may be of cylindrical form and made up of longitudinal ribs intersected by transverse rings, and is attached to a closure cap 40. The longitudinal ribs serve as guides for longitudinal sliding movement of the guard grid on the cylindrical intake duct 70. When the closure cap 40 is moved by preferably hydraulically operated sliding linkage 65 to the position shown to uneven the air intake orifice, it carries the guard grid 60 to the operative position. Preferably, the guard grid is of stainless steel or is a plastics injection moulding. In the alternative arrangement shown in Fig. 6, a pivoted closure flap 41 carries an elbow-shaped guard grid 61.
