Title: Foot measuring appliance
IPC: A43D1/02
Filed: 1951-02-01
Abstract: 700,513. Foot measuring appliances. SVENSKA SKOFABRIKANTFORENINGEN. Feb. 1, 1951 [Feb. 1, 1950], No. 2564/51. Class 17(3) A foot measuring instrument comprises in combination a rule 13 adapted to contact the tip of the big toe of a foot placed on a plate 8 and movable by a slide 23 in a central line, shown in Fig. 7 extending from centre of heel to space between roots of big toe and adjacent toe along a slot 12; a second rule 14 movable along a slot 15 in any vertical face of the instrument, in a line which crosses the central line at a point behind the heel at a predetermined angle, of 5 degrees in the example shown, to contact the inner ball of the foot, these two rules being interconnected so as to move in a predetermined relation. The rule 14 is adjustable to set the index mark 27 opposite the inner ball of the foot when such foot is normal, and to move it when the foot departs from normal. A third rule 16, adapted to contact the outer side of the foot at its widest part is connected to the second rule to be movable therewith in the longitudinal direction of the foot along a slot 17 in the opposite vertical face of the instrument, and also independently, in the transverse direction, to measure the foot width. It is also connected to a pointer which indicates the length and width of the foot. The device is reversible, having two foot-supporting plates 8, 9, so as to measure both right and left feet, and the mechanism linking the various rules is enclosed in a cavity formed between these plates 8, 9. Fig. 4 shows how the various rules are interlinked, and the relationship of the paths of movement of the rules in relation to the lines of Fig. 7. A screw 33 adjusts the rule 16 and locks it in adjusted position. A pointer 37 on a member 30 which carries the third rule 16 reads against a scale on the upper surface of plate 8 or 9 graduated to give the foot length and also against a transverse scale E-K to give the corresponding foot width. A modified construction of instrument is shown in Fig. 11 in which the movable elements are supported on one plate only, i.e. 39. The slot 12 is rendered unnecessary by fixing the rule 13 to a sleeve 45 slidably surrounding a rod 43 and movable. in slot 15. The rod 43 is slidably fixed in a hole in slide 18 and the mechanism which is connected to rule 14 is substantially as in the first modification. Slides 18, 45 are coupled by linkages shown, the outer end of the bell crank lever 46 of which carries a reel 52 a peripheral groove of which is constrained to move along the edge of a guideway 55 on the plate 39. This guideway is shaped to maintain the desired relationship between the movements of rules 13, 14 within the entire range of measurement. Where feet change radically, e.g. as between different countries, the guideway 55 is modified.

Patent GB-480480-A (GB)
Title: An improved process for the production of an adsorbent mass
IPC: C01B33/113
Filed: 1937-01-29
Abstract: An absorbent mass chiefly consisting of silica is obtained by decomposing siliceous raw materials by fusion with such an excess of alkali that the product will disintegrate on treatment with water with the deposition of the water-insoluble constituents as a finely divided precipitate, treating the product with water to cause such disintegration thereof, separating the finely divided precipitate from the solution and decomposing the precipitate with acids or acid salts to produce a pulverulent silicic acid.  The acid decomposition may be effected in the presence of electrolytes, e.g. soluble silicates, or non-electrolytes, e.g. organic substances.  The product may be wholly or partially washed and/or freed from water.  Finally it may be calcined.  According to an example, water-washed insoluble residues from waterglass filtration are boiled with dilute hydrochloric acid, one or several times with intervening decantation or filtration.  The product is washed, dried and calcined.  The Specification as open to inspection under Sect. 91 comprises also the preparation of melts in such a manner that in the subsequent preparation therefrom of waterglass, a large amount of water-insoluble silicates are obtained for submission to the subsequent acid treatment.  This subject-matter does not appear in the Specification as accepted.

Abstract: 551,390. Valves. PARKER, A. LA R. March 3, 1942, No. 2774. [Class 135] A valve, particularly adapted for controlling liquid fuel, of the kind comprising a flexible rotary valve member adapted to be distorted into sealing engagement with the valve ports in the casing by an element rotated with the valve has this element arranged to slide on a fixed cam on the casing so as to displace it away from the rotary valve member when this is turned from the closed position. In the form shown in the Figures, the valve member comprises a thin shell 7 formed with diametrically opposed ports 12 adapted to co-operate with ports 3, 4 in the casing. A bridge 8 across the upper end of the valve member is formed with a rectangular slot adapted to engage the end of an actuating spindle 14 rotatably mounted in the casing and fitted with a handle 15. The spindle is provided with a packing 17 acted on by a spindle 18 and is formed with a flange 16 held in a recess in the casing by a spring 24 bearing on the bridge 8. The distorting member comprises a U-shaped spring 19 with a rectangular slot to engage the end of the spindle and with depending arms 21 formed with curved projections 22 adapted to press against the inside of the valve member. The lower ends of the arms 21 are slotted and bent outwardly to form wedge-shaped projections 23 passing through slots 11 in the valve member. These projections co-operate with a fixed cam-ring 27 having a pair of deep recesses 29 and a pair of shallower recesses. When the valve is closed the projections 23 snap into the deep recesses so allowing the spring arms to distort the valve member into sealing contact with the valve ports. When the valve is moved to the open position the spring arms are first withdrawn and then snap into the shallow recesses to hold the valve in its open position. The ports in the casing may be circular or may be oval with the longer axis parallel to the axis of the valve. In a modification, the distorting member comprises a pair of levers pivoted to an extension of the actuating spindle and pressed apart by a helical spring. The extension has a through passage and a depression at the bottom engaging a spring-pressed ball.

Title: Method of producing polyolefine tube
Inventor: RILEY JACK LENDYMORE
IPC: B29C48/10
Filed: 1964-01-24
Abstract: 1,041,642. Treating polyolefine tubes. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd. Jan. 14, 1965 [Jan. 24, 1964], No. 3202/64. Headings B5A and B5B. Polyolefine tubes (including thin-walled tubes) which have been bi-axially oriented are treated by passing the tube through an " under-size " die maintained at a temperature between 120 and 350 C., the speed at which the tube is passed through the die being such that only a superficial layer of the tube is heated significantly. The term " under-size " is stated to mean that the diameter of the orifice of the die must be smaller than the outer diameter of the tube so that the outer surface of the tube is pressed into intimate contact with the die wall as the tube is passed through it, but that the inward radial pressure in the wall of the tube is not sufficient to prevent movement of the tube through the die. The temperature of the tube before it is passed through the die is not critical, provided that it has sufficient mechanical strength to permit its being passed through the die without being damaged; to ensure this, the temperature of the tube before its passage through the die should not exceed about 70 C. The operation should not significantly change the dimensions of the tube. In an example, bi-axially-oriented tubing of high density polyethylene with an external diameter of 0À786 inch and a wall thickness of 0À02 inch and having a rough " hairy " surface in its " as made " state, is forced through a tool steel die having a circular orifice of 0À771 inch diameter, i.e. 0À015 inch under-size, at a rate of 20 ft./minute, the die being maintained at 210 C. In the other example, the tube is passed through the die at 26 ft./minute, the die temperature being 260 C. In both examples, the tube after passage through the die is free from " hairiness." The process also removes from such tubes any undesirable matt coating.

Abstract: 104,686. Bliss Co., E. W., (Assignees of Klocke, W.). March 8, 1916, [Convention date]. Cupping.-A press for drawing shells of various shapes from blanks D comprises a reciprocating plunger A, a stationary die B, and a movable blankholder C. During the drawing operation, the holder and plunger move together, and after the plunger is withdrawn, the holder is given an independent movement to discharge the shell from the die. The holder is carried by the upper part of a frame E comprising two parts E<1>, E<2> connected by toggles F and a link G having a pin T engaging a slot S in an operating-arm R, which is oscillated by a cam-groove in a disk L on the crank-shaft H through a pin N, link U, and lever P. The frame E is carried by four rods I connected to the plunger cross-head J, and its parts E<1>, E<2> are moved relatively on one another by the cam through the levers, links, and toggles. The punch first descends until it engages the blank and the toggles are straightened to bring the holder up to the blank. On withdrawal of the plunger the upper part E<1> and the holder C do not at first move, since the toggles are broken by the action of the cam. When the part E<1> is at its upper position, the toggles are straightened and the blank knocked out.
Patent GB-462869-A (GB)
Title: Method of and apparatus for the magnetic recording and reproduction of sound
IPC: G11B5/29
Filed: 1936-02-04
Abstract: 462,869. Electromagnetic sound recording and reproducing apparatus. INTERNATIONALE TOBIS MAATSCHAPPIJ NAAMLOOZE VENNOOTSCHAP. Feb. 4, 1936, No. 3330. Convention date, Feb. 4, 1935. [Class 40 (ii)] Relates to a method of magnetic soundrecording in which the alternating field to be recorded and a superimposed constant magnetic field act upon a sound carrier, e.g. of band or disc form, through the intermediary of recording magnets, and consists in causing the alternating field to be recorded to become operative in the form of two components of equal intensity which are displaced in phase through 180‹, the constant magnetic fields appertaining to each component being of the same direction and of the same intensity. When reproducing such a record, the two components of the recorded alternating field are recombined in correct phase into a single alternating potential. If desired, the sound carrier may be given a strong constant premagnetization, in which case, the direction of the constant magnetic fields superimposed on the alternating fields is caused to be opposite the direction of the pre-magnetization. Fig. 2 shows a recording arrangement in which the amplified microphone currents are applied to the primary winding 1 of a transformer, the two ends of the centre-tapped secondary winding 2 of which are connected to the two free ends of the windings of the four recording magnets 3, 4, 5 and 6 arranged as shown on opposite sides of the sound carrier 9, said windings being connected in series. The centre-tapping of winding 2 is connected through battery 7 to the electric centre 8 of the magnet windings. With this arrangement, one component of the alternating field acts on the windings of the magnets 3, 5 whilst the other component, displaced in phase through 185‹, acts on the windings of the magnets 4, 6. Fig. 3 shows a modification of this arrangement in which two magnets 10, 11 are arranged on one side of the sound carrier 9 whilst a single magnet 12 is provided on the other side thereof, the extent of the core 12<1> transversely to the direction of movement of the band 9 being exactly the same as that of the two cores 10<1>, 11<1> including the spacing therebetween. In both arrangements, the magnet cores on opposite sides of the sound carrier are slightly displaced relatively to one another in the direction of movement of the carrier. Similar arrangements are described for reproducing, Figs. 4 and 5 (not shown) but in this case the battery 7 is omitted and the wire leading from the point 8 and including the winding on core 12<1>, Fig. 3, may be dead ended or omitted altogether.
