Title: Recovery of crude hecogenin from agave leaves
IPC: C07J75/00
Filed: 1962-11-08
Abstract: Crude hecogenin is recovered from the juice of agave leaves in which recovery process the juice is submitted to acidic hydrolysis under pressure and at a temperature exceeding 100 DEG C. and the precipitate that forms containing the crude hecogenin is separated and treated with an aqueous alkali solution. The reaction mixture may not contain any added acid or may contain up to 10% by weight of added acid, for example sulphuric acid.  The treatment with an aqueous alkali may be preceeded by an extraction of the product of hydrolysis with an alcoholic acid solution and the hecogenin is recovered from the resulting extract with the aqueous alkali solution.  The acid used in the above process may be sulphuric acid. The hydrolysis step may be effected continuously by passing the reaction mixture through a reaction vessel in which the temperature is maintained at at least 150 DEG C. Specifications 797,384 and 957,655 are referred to.

Filed: 1959-12-11
Abstract: 898,939. Boring earth &c. SOLETANCHE. Dec. 11, 1959, No. 42214/59. Class 85. In apparatus, for making bore holes, of the kind comprising a tubular cutter which is dropped, or otherwise forced, into soft ground to become filled with a core which is removed when the cutter is brought to the surface, the core is retained in the tubular cutter by spring blades 7, arranged as a slidable assembly, which is projected from the lower end of the cutter to discharge the core therefrom. A lower section 1 is connected to an upper section 2 by an annular member 4 rigidly connected to a cap 3 by a sleeve 9. The blades 7 are spaced around a head 11 and are bent over to be clamped by bolts 13 between the head 11 and a plate 12. A sleeve 14 secured to a shackle pin member 17 for connecting to the actuating cable is secured to the head 11 and passes with clearance through the plate 12 and the flange 8 of the connection 4, so that water may pass upwardly between the blades 7 into the space between the head 11 and plate 12 and into the space between the sleeves 14, 9. Passages 6 also vent water from the space between the flange 8 and the piston like assembly 11, 12. The blades 7 are thickened at the lower ends to form retaining shoulders for the cores, and the lower ends of the blades and the lower edge of the element 1 are bevelled to facilitate the cutting of the ground. The sleeve 14 is anchored, during the impacting of the cutter, by a key 19, which, when the cutter is brought to the surface, is removed so that, whilst the sections 1, 2 are supported by cables attached to suspension eyes on the cap 3, the assembly 17, 14, 11, 12, 7 is allowed to gravitate until the member 17 rests upon the flange 8, the spring blades 7 being then wholly outside the element 1. The blades have a resilient tendency to spring outwardly away from the core, which is thus released.

Abstract: 1,069,632. Ventilating. UNION CARBIDE CORPORATION. Oct. 29, 1963, No. 42566/63. Heading F4V. [Also in Division H5] In a method of ventilating for reducing the spread of airborne infections, air is sterilized by means of ultra-violet radiation and circulated through a zone, while the pressure in the zone is maintained at a value different from that of the exterior of the zone. As shown, rooms 23-29 in a hospital ward are supplied with air from a sterilizing unit 35 via ducts 36-45 and ceiling-mounted distributers 46-54, air being withdrawn from the rooms through outlets in the floor and recirculated to unit 35 at such a rate that the pressure in the rooms is greater than that outside. Air leaking from the rooms into corridors 21, 22 is recirculated to unit 35 which also receives outside air and may be connected in a heating or air-conditioning system. Rooms 30-32 have ceiling distributers 30a-32a connected to a separate sterilizing unit, while rooms 33, 34 are provided with individual sterilizing units 58, 59 which are arranged to take in room air at floor level and discharge sterilized air towards the ceiling (Fig. 4, not shown). Fresh air is supplied to, and stale air withdrawn from, rooms 33, 34 at rates sufficient to maintain the desired overpressure therein. The sterilized air may be supplied to and withdrawn from the rooms through inlets and outlets mounted respectively at the top and bottom of one wall and connected to a sterilizing unit individual to but external of the room (Figs. 6 and 7, not shown). In highly infectious areas, such as operating theatres, the pressure therein is maintained below that of the surrounding areas to prevent the escape of airborne infection (Fig. 8, not shown). A more concentrated stream of air may be directed over an operating table by providing a relatively large opening (95, Fig. 9, not shown) in the ceiling directly above the table or by connecting a flexible hose (104, Fig. 10, not shown) to the duct (102) supplying sterilized air. Alternatively a portable sterilizing unit (133) having a flexible discharge conduit (134) may be employed. The sterilizing units (Fig. 3, not shown) may comprise an inlet duct (122), a fan (120), a filter (121), a plurality of chambers (111, 112, 113) containing ultra-violet generating tubes (114, 115, 116) and helical baffles (117, 118, 119), and an outlet duct (123). The chambers may be of rectangular, circular or hexagonal cross-section.
