Title: Improvements in or relating to motion translating devices
IPC: G06M1/26
Filed: 1952-07-08
Abstract: 708,895. Counting-apparatus. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. July 8, 1952 [July 12, 1951], No. 17203/52. Class 106 (1). [Also in Group XXIV] Mechanism, especially for driving a counter, comprises two independently rotatable members, driving means coupled to the latter for rotating them at different rates, and yieldable biasing means urging the members towards a predetermined position relatively to each other, the coupling between one of the members and the driving means being interrupted for a predetermined arc of each revolution of said member. The mechanism may be connected between a shaft 35, the revolutions of which are to be counted, and the units wheel 7 of a counter in order to provide a snap action as the wheel is moved from the " 9 " position to the " 0 position. The shaft 35 drives a pinion 41 meshing with a gear 37 and a mutilated gear 39 having the same number of teeth but in which the teeth are more closely spaced to provide a portion 47 which is not toothed. The gears 37, 39 are coupled by a torsion spring 57 the ends of which bear on pins 53, 55 in the gears respectively. The gear 39 is fast, and the gear 37 freely rotatable, on the shaft 11 to which the units wheel 7 is secured. Thus, as the shaft 35 rotates, the units wheel is advanced continuously from 0 to 9, during which movement the gears 37, 39 are relatively displaced to tension the spring 57, and then the spring rapidly advances the gear 39 by an amount corresponding with the cut-away portion 47. The advance of the units wheel from 9 to 0 and the advancing movements of the higher order wheels, interconnected by transfer pinions 31, thus occur rapidly. The pins 53, 55 are at different radial distances from the shaft and consequently, the operation is the same for either direction of movement. The spring 57 may be replaced by a gravity-operated device and, if desired, the gear 39 may have several cut-away portions to produce a corresponding number of snap actions. The wheel 7 may be unmarked so that all the number wheels move digitally.

Title: Improvements in process of producing sintered hard metal alloys
IPC: C22C1/05
Filed: 1935-06-14
Abstract: Sintered hard alloys are made by mixing one or more hard compounds of elements of the third, fourth, fifth, and sixth periodic groups, for example, boron carbide, or borides, carbides, or nitrides of tungsten, titanium, tantalum, or niobium, with or without the addition of one or more of the elements themselves, with an inorganic compound, such as an oxide or carbonate, of a metal or metals such as cobalt, nickel, or iron, the decomposition of the compound being effected subsequently to the formation and working of the shaped pieces.  The decomposition may be carried out simultaneously with the final sintering.  For example, a mixture of carbides may be ground in a ball mill with a mixture of nickel and cobalt oxides, pressed, and formed into articles such as saws, files, or grinding wheels, and afterwards sintered in hydrogen in a carbon tube resistance furnace at about 1600-1700 DEG  C. for 2-3 hours.

Title: A valve device for a respirator for use in closed-circuit respiration
IPC: A62B9/02
Filed: 1962-05-07
Abstract: 991,865. Respiratory appliances. O. H. DRAGER, [trading as DRAGERWERK, HEINR. & BERNH. DRAGER]. May 7, 1962 [May 5, 1961], No. 17558/62. Heading A5T. In a lung-controlled oxygen supply valve for a closed circuit respiratory apparatus the diaphragm carries a valve seat which, in the condition of rest, bears against a sealing member on the control chamber side of the diaphragm while the opposite side of the diaphragm communicates with the ambient atmosphere. Air, circulating within the system, is received into the control chamber 1, from a breathing bag, through a connection 8 and passes out through a second connection 9 to a breathing mask. The diaphragm 10, which has a port 17 leading to a valve seating 15, is normally held against a sealing member b by a spring 14, this spring being weaker than a spring 12, which holds the member b upward, in its support a, against its abutment flange c. When there is an insufficient volume of gas in the system the diaphragm is drawn down by the user's inhalation, so depressing the member b and opening the oxygen supply valve 5 by means of rod 7. On the other hand, if the pressure in the system becomes too great, exhalation by the user lifts the diaphragm 10 clear of the seal 16 and the excess volume of gas escapes through a lightly loaded non return valve 18 and an outlet 19 to atmosphere. A bleed orifice 13 allows a continuous, restricted supply of oxygen to flow into the system to ensure adequate scavenging.

Title: Improved polymer recovery process and apparatus therefor
Filed: 1957-06-04
Abstract: Solid polymers of 1-olefins are separated from hydrocarbon solutions thereof, by dispersing the solution into water of low temperature at a solution to water ratio such that the resulting dispersion temperature is below the solidification temperature of the polymer, the hydrocarbon and water being maintained in the liquid phase and then spraying the resulting dispersion through a vapour space into a stripping zone containing water at above the vaporization temperature of the hydrocarbon.  The dispersion may be sprayed into the vapou space on to a surface wetted with heated moving water, such wetted surface comprising a vertically disposed continuous concave surface to which water is introduced tangentially.  It is preferred that a hot inert gas, e.g. steam is introduced through the water in the stripping zone into the vapour space.  Apparatus for carrying out the process is described and claimed.  Specifications 790,195, 799,392, 804,641 and 835,300 are referred to.

Title: Improvements relating to absorbent fibrous sheet material
IPC: B01D39/18
Filed: 1957-06-04
Abstract: 862,545. Laminates; reinforced paper. KIMBERLY-CLARK CORPORATION. June 4, 1957 [June 13, 1956], No. 17718/57. Classes 96 and 140. Sheet material suitable for use as towelling, filter material, packing material, acoustical and decorative sheeting, for making expendable garments and for other purposes, comprises one or two layers of crepe tissue paper, cotton or other non-woven fibrous cellulosic, synthetic, or other material 6, Fig. 2, bonded to, or on both sides of, a reinforcing rectangular or diamond woven or non-woven lattice, 1, of threads 2, 3, the material 6 being subjected to treatment to produce a puffy surface. The threads 2, 3 which may be of low-twist, multi-filament construction, are bonded together and to the material 6 by adhesion, such as polyvinyl acetate, which may be applied to all the threads or to those extending in one direction only. Alternatively bonding may be effected by the inclusion of thermo-adhesive fibres in the threads 2, 3 or the material 6. The treatment of the material to produce a puffy surface may comprise mechanical distortion by a swinging tenter having plates 7, 8, Fig. 15, which grip the edges of the material and are caused to swing in opposite directions about a pivot 10 carrying a connecting link 9 for the plates. Such treatment is considered to cause decrimping of fibres in the material 6 which are anchored at points in their length by the adhesive threads or the like 23, and the partial disengagement of interlocking fibres which are anchored at one point only, the fibres thereafter buckling outwardly to give the puffy appearance. Another form of treatment comprises spraying water or other fibre-loosening agent on to the material through a pipe 32, Fig. 16, subjecting the material to an air or other fluid blast from a pipe 33 to distend it, and thereafter drying it in an oven 34. Material with a diamond grid may be treated by stretching longitudinally, as by pairs of rollers running at different speeds, and laterally by rollers or conveyer chains adapted to grip the edges of the material. The material may comprise a layer or layers 6 on one side of the grid and a layer of other material, for example of highly carded rayon, on the other side. Treatment to impart wetstrength, fine resistance, wrinkle resistance or other properties may be applied before or after the puffing treatment. The spaces between the elements of the grid are preferably larger than the length of the fibres in the material 6, for example when crepe paper is used having fibres 1/16 inch or less in length the grid spacing may comprise 15 strands or less per inch.

Abstract: 831,705. Travelling grates. G.K.S. COMBUSTION CO. Ltd. Aug. 14, 1958 [June 3, 1958], No. 17758/58. Class 51 (1). In a grate bar for a travelling grate having transverse rows of grate bars mounted on bulb bars 15 the web of the grate bar having ridges 28 and grooves 29 following curves generated about the axis of the bearing engaging the bulb bar, at least one of the ridges or grooves is higher or shallower than normal so that it touches the bottom or top of a normal groove or ridge on an adjacent bar to hold the bars parallel. The angular gap 16 connecting the bearing 13 which engages the bulb bar 15 to the lower edge of the bar is wider on alternate bars so that the bars move with a scissor action as they move from the forward run to the return run and remain at different inclinations on the return run, Fig. 3. Flange-like projections 32 at the lower rear edges of the bars, Fig. 4, prevent the trailing edges from fouling the support rollers of the grate, and grooves 33 in the lower part of the web of the bar interconnect the recesses 29 and allow air to pass freely between the bars. Specification 626,292 is referred to.

Title: A method of refining lubricating oils
IPC: C10G45/00
Filed: 1961-05-16
Abstract: Machine oil is prepared from a naphthene base oil by subjecting the base oil to catalytic hydrogenation in the presence of a sulphur resistant catalyst with a hydrogen containing gas, in the liquid phase, at a hydrogen partial pressure between 60 and 90 atm. abs., at a temperature between 320 DEG  and 400 DEG  C., at a space velocity between 0.1 and 1 v./v./m., and with a specific gas volume between 50 and 600 st. cu. m./tonne oil, until the viscosity of the oil is reduced to a predetermined value from one which is 10% to 25% higher. Alkyl aromatics may be removed from the refined product by vacuum steam distillation at 140-220 DEG  C. The naphthene base oil may be stored in a protective atmosphere from the time of production to the time of refining.  The hydrogen containing gas may be a reformer exhaust gas which is conducted straight through the process. Alternatively, the hydrogen containing gas may be recycled, with removal of the major portion of its hydrogen sulphide content by known methods prior to returning to the process.  Desirably the temperature in the reactor is maintained at a uniform level throughout, such that the temperature differentials do not exceed 50 DEG  C.  The catalyst may preferably have a bulk density between 0.70 and 0.78 gm./c.c.  The oxidation stability of the refined product may be improved by the addition of 0.1-0.5% of hydrazine.
