Abstract: 1314725 Leather substitutes CARL FREUDENBERG 23 April 1970 [24 April 1969 4 Feb 1970] 19586/70 Heading B2E [Also in Division D1] A non-woven fabric bonded by a heat coagulated binder in first areas only of the fabric, second areas of the fabric distributed amongst the first areas being substantially free of the binder. In one embodiment a fleece 3 of 70% viscose rayon and 30% polyester shrink fibre is needled, shrunk in area by heating, impregnated with a heat sensitive coloured polyacrylate dispersion and passed between externally gas heated textured rolls 5, 6 having an irregular raised pattern in the form of veins. The binder is thereby displaced from the vicinity of the raised parts of the rolls and then coagulated. The fabric is then quenched in a cold water bath and the uncoagulated binder washed out with water, dried and split.  Each half of the web is then coated by being pressed onto a layer of polyurethane spread on a carrier which is subsequently removed, to give a glossy or matt coated fabric used as a leather substitute. In a second embodiment the impregnated fabric is passed under a heated roll (21 Fig. 2, not shown) having raised portions (1), the temperature, pressure, and the speed of the fabric being such that the binder in the pressed areas (1') is coagulated. The uncoagulated binder is then washed from areas (4', 4") to give a "spot-bonded" fabric in which spots (1') are regularly arrayed.

Abstract: 256,987. Smidth & Co., Aktieselskabet, F. L., (Assignees of Smidth & Co., F. L.). Aug. 14, 1925, [Convention date]. Ball and like mills. - In the fine grinding of cement or the like in ball or tube mills, the grinding-bodies used in the mill are removed at intervals from the material being ground, freed from the film of adhering material with which they are coated, and then returned for further action on the material. From a suitable point of the mill, the grinding-bodies may be conducted through a clear space of the mill, in which they are wholly or partly cleared, towards the inlet end in order to be again mixed with coarser material to be ground. The grinding-bodies may be removed from the, mill and subjected to a mechanical or chemical cleaning process and then returned to the mill. Figs. 1 and 2 show the fine grinding-chamber 1 of a ball mill having double end-walls 2, 3 at the supply and discharge ends, respectively. Radially-arranged blades are provided in the double walls to move the material from the periphery towards the centre of the mill. An axially-disposed tube 7 held in position by means of bent stays 12 attached to bolts 13 arranged in the spaces between the lifting ribs 6 on the inner wall of the mill is provided with an internal worm conveyer 7. Two curved hollow scoop arms 10 at the free end of the tube 7 lift the grinding-bodies out of the charge 11 and conduct them into the tube 7 along which the conveyer 8 conveys them to the supply end 4 of the chamber 1 where they again pass into the chamber through a passage 9. The Specification as open to inspection under Sect. 91 (3) (a) states that the grinding-bodies may be subjected to the action of a current of compressed air either inside or outside of the mill. This subject-matter does not appear in the Specification as accepted.

Title: High-load screw connection
IPC: F16B33/02
Filed: 1971-04-19
Abstract: 1339627 Screw connections; screw threads H BIERI 19 April 1971 [26 Jan 1970] 20262/71 Headings F2H and F2Q In a high load screw connection for joining constructional components 36 with a bolt 4 having an external thread 2 coacting with an internal thread 1 in a component or in a nut, the pitch h of the thread 2 is less than that of the thread 1 and the axial flank clearance a between the two threads is greater than the entire pitch difference over the engaging thread length. In addition the bolt 4 has mounting means in the form of a threaded end 17 for fitting a prestressing appliance 8 whereby axial prestress can be exerted on the bolt 4 in order to avoid a relative twisting of the thread members under load. The threads 1, 2 are at least approximately trapezoidal in shape with straight supporting flanks having included angles α, # less than 45 and preferably between 15 and 30 degrees and differing by less than 5 degrees e.g. approximately 24 and 27 degrees respectively. The pitch h is more than one and a half times the depth d of the course of the external thread, preferably between 2À2 and 2À7 times. The pitch of the internal thread is larger than the pitch h of the external thread 2 resulting in linearly increasing distances S0, S1, S2 between the flanks within mutually engaging thread courses and the axial clearance a is large enough to allow relative twisting without clamping for a limited length of engagement between the threads. If load is applied in direction P it is initially supported solely at e but with increasing load, the material of the bolt stretches and as the result of plastic and elastic deformation the load spreads over and is eventually supported by the remaining courses. The connection may be cast in ball graphite, light metal, grey iron or of copper. Since the threads would clamp if relatively turned to engage beyond the limited length determined by the pitch difference, an hydraulic device 8 is provided to prestress the bolt 4 and the nut 18 can be tightened while the bolt is stretched, thereafter maintaining the prestress in the screw connection joining the machine parts 3, 6 after removal of the device 8. A protective cover 21 is fitted after the device 8 has been removed.

Title: Washing machines
IPC: D06F39/08
Filed: 1964-05-15
Abstract: 1,071,732. Dishwashing machines. W. HOLZER. May 15, 1964 [May 30, 1963], No. 20392/64. Heading A4F. [Also in Divisions D1 and F2] In a dishwashing machine the tub is first filled with water to a predetermined level, and a washing agent is then flushed into the tub by additional water introduced to the tub via a washing agent container. The flow of water to the tub is controlled by a valve 10 having an inlet passage 1 connectible alternatively to outlet passages 14 and 17, passage 14 being connected directly to the tub and passage 17 being connected to the tub via the washing agent container. In Fig 3, passage 17 is initially closed by a flap 15 under the bias of a bi-metallic spring 18. The flow of water to valve 10 is controlled by a solenoid valve, energization of which simultaneously energizes a heating coil 19 for spring 18, whereby after a predetermined amount of water flows via passage 14, flap 15 shifts to open outlet 17 and to close outlet 14, the solenoid valve being de-energized after a predetermined amount of water flows via passage 17. In a modification the flap is actuated by a linkage connected to a bellows which expands when a heating coil positioned therein is energized. In Fig. 5 the main flap valve is eliminated, water flowing through passage 14 past a collapsed bellows 25 and being prevented from flowing through passage 17 by a spring-biased flap 27. On energization of coil 19 in bellows 25, the latter expands to close passage 14, when the increased water pressure in passage 17 opens flap 27. In Fig. 6 a flap 15 is normally positioned centrally of passage 1 to allow equal flow through passages 14 and 17. On slight deflection of flap 15 to one side or the other by external means, the water pressure serves to continue said deflection until flap 15 closes the relevant passages 14 or 17.

Title: Improvements in or relating to the production of alumina
IPC: C01F7/36
Filed: 1961-06-06
Abstract: Eta-alumina is produced by spraying a mixture of alcoholates, obtained by reacting aluminium triethyl with ethylene at a temperature between 65 DEG  and 150 DEG  C. and a pressure from 200 to 5,000 p.s.i.g. and oxidizing the reaction product with a gas containing free oxygen, on to the surface of an agitated body of water maintained above 50 DEG  C. thereby forming separate phases of hydrated alumina slurry and alcohols, separating the alumina slurry from the alcohols, and thereafter drying and calcining to form eta-alumina.  Any alchols contained in the hydrated alumina slurry may be removed by leaching with a suitable solvent, e.g. diethyl ether, methanol, butanol or acetone, by stripping with an inert stripping medium, e.g. steam or nitrogen, or by a combination of solvent extraction and stripping.  The alcohol phase, after separation, may be further treated to remove the water from the alcohols and to further separate the individual alcohols.  Any conventional spray or atomizing nozzle may be used to subdivide the alcoholates.  Further subdivision is aided by the use of an atomizing gas which can be any inert gas.  The dried hydrated alumina, which is mainly a -alumina monohydrate may be calcined at a temperature between 600 DEG  and 1,200 DEG  C. for 0.5 to 24 hours to form etaalumina.
