Title: Improvements in or relating to separable sliding clamp fasteners
IPC: A44B19/60
Filed: 1966-02-25
Abstract: 1,140,664. Moulding sliding clasp fasteners. H. HANSEN. 25 Feb., 1966 [28 Dec., 1965] No. 8505/66. Heading B5A. [Also in Division E2] A separable sliding clasp fastener of the kind comprising two rows 1, 2 of coupling links secured to two stringer tapes respectively, each of said rows being constituted by a succession of loops formed in a plastics monofilament, a sliding member for effecting the engagement and disengagement of the coupling links and a separable end stop located at one end of each of the rows of coupling links and having two channel-shaped parts 7, 8 by which the last loop at the said one end of each row is secured to the corresponding stringer tape, is characterized by the fact that each channel-shaped part has on the free edges of its side flanges teeth which are pressed through the corresponding stringer tape from the front side, bent round the rear side of the stringer tape and pressed into it, one of said parts carrying a connecting piece of the end stop, the connecting piece 21 having a socket 22 for receiving the other part. Each channel shaped part straddles a bead 5 or 6, the bead being produced by first applying reinforcing strips 27 and 28 (not shown) of thermoplastic material to respective sides of the pair of tapes, heat moulding the strip 27 to form the two beads and thereafter cutting through a web produced between the beads in the heat moulding operation. The parts 7 and 8 enable the fastener to be made in a fully automatic manner in a continuously progressive operation starting with a web of material which consists of two long lengths of tape, each tape carrying on one side a chain of the coupling links the chains being interconnected. In a first station gaps are cut in sequence in the chains of coupling links to produce the coupled rows for individual fasteners, then for each fastener, in the next station, the reinforcing strips 27 and 28 are applied and the beads 5 and 6 are formed by the heat moulding operation; in the following station the punching operation is performed by which the beads 5 and 6 are cut free from one another and at the same time a hole is formed in the tapes beyond the ends of the beads, in the next station the sliding member is mounted on the rows of coupling links by being passed through the hole and in the next following station top stops are applied; the next station fits the channel shaped parts 7 and 8 to the beads and the subsequent station clamps these to the tapes by bending the teeth; the connecting piece 21 is entered into the hole and slid on to the parts 7 and 8 in the next station and secured by a punching operation and in the final station two cuts are made through the tapes to sever the finished fastener from the tapes and to define the end of the next fastener.

The compounds are made by treating a compound of the formula <FORM:0723913/IV (b)/2> where X is a radical convertible by reduction or hydrolysis into an amine group, with an alkylene dihalide, Hal.(CH2)nHal; treating the 10-haloalkyl phenanthridine formed with a sodium alkoxide CH3(CH2)mONa and subsequently converting the groups X into amino groups. Alternatively the same starting material may be treated with an alkoxyalkyl ester of an aryl sulphonic acid Ar.SO3-(CH2)nO(CH2)mCH3 followed by conversion of the groups X into amino groups.  The group X convertible into an amino group may suitably be a nitro, acylamino or carbalkoxyamino group.

Title: Comminution device
IPC: B02C23/16
Filed: 1977-03-03
Abstract: In this comminution device, elongated rotor blades (15) which interact with stationary blades (11) are attached in each case to rotor discs (7) arranged with axial spacing from one another. Each rotor blade (15) has a leading cutting edge (5) which moves on a circular rotation path (9), and an outer surface (23) which extends in the direction of the chord with respect to the rotation path (9) between the cutting edge (5) and a trailing edge (17) of the blade (15). The trailing edge (17) lies as closely within the rotation path (9) as is possible without interfering with the rotation of the rotor. An inner surface (31) which is parallel to the outer surface (23) and a trailing surface (27), perpendicular thereto, of each rotor blade (15) rest virtually over their entire extents on carrying surfaces (25) of the rotor discs (7). With this geometry and arrangement, bending stresses of the rotor blades (15) can be kept to a minimum if the rotor blades (15) are dimensioned to have a degree of rigidity which is just sufficient for the loading which occurs. <IMAGE>

Title: Process for the preparation of zinc and cadmium sulphides and selenides
IPC: C09C1/12
Filed: 1955-03-28
Abstract: Zinc or cadmium sulphide or selenide is prepared by passing gaseous hydrogen sulphide or selenide into a solution of a zinc or cadmium salt of an organic acid or a zinc or cadmium complex ammonium salt in an alkanol of 1-5 carbon atoms whilst maintaining conditions of reflux.  The preferred solvents are methanol and ethanol, and the preferred salt is an acetate, but zinc propionate, salicylate, valerate, oleate, and caprolate, zinc ethyl sulphate, zinc ammonium chloride, cadmium ammonium chloride and cadmium ammonium bromide are also specified.  If desired, heavy metal impurities may be first precipitated with hydrogen sulphide or selenide and separated before the precipitation of the main product.  A suitable concentration of salt in the solution is 0.1-0.15 parts by weight per part of solvent; a glass vessel with reflux condenser or a column still may be employed and the process may be carried out batchwise or continuously; after precipitation the solids may be filtered off, washed with a further quantity of the solvent used and dried e.g. at 60-120 DEG C., preferably at 190-20 m.m. of mercury or less. Satisfactory results are obtained with commercial and with anhydrous alcohols and salts.

Abstract: 995,961. Jig washers. STAMICARBON N.V. March 4, 1964 [March 6, 1963], No. 9207/64. Heading B2H. A jig washer comprises one or more compartments 2, 3, Fig. 1, in which the pulsations of the separatory liquid are produced by varying the air pressure in one or more air chambers 16, the arrangement being such that the air supply and discharge are controlled by the level of the liquid in the chambers. Raw coal fed through an inlet 6 is separated on screens 4, 4<SP>1</SP>, the shale and the middlings discharging respectively through float-controlled flap valves 8, 12 and the clean coal discharging over a weir 14 into a shoot 15. An air distributer pipe 17 is provided with inlet and exhaust valves 18, 20 for supplying and discharging air to and from the chambers 16. Electrode contacts 40, 42, as shown in Fig. 4, are mounted on the walls of the air chambers, at least one of each pair being adjustably-mounted to vary the upper and lower working limits A-B of the liquid; the contacts are incorporated in an electrical circuit to electromagnetically operate a valve arrangement 63, Fig. 6, which controls compressed air to and from a piston 61 mounted on the stem of the air valve 18 (or 20). The electrical circuit includes adjustable timing relays and provision is made so that air cannot be supplied until the exhaust valves are closed in the associated chamber. The arrangement permits adjustments to obtain a longer jig stroke in the first compartment than the second and also a different time delay for each compartment. Only one electrode contact may be employed in each chamber instead of two, to open or close either of the inlet or exhaust valves, the opening or closing of. the other valves being effected by time relays. Instead of employing electrode contacts in the air chambers, float switch, dielectric switches and light or radio-active sources provided with detectors may be used.
