Patent FI-965226-A (FI)
Inventor: OUELLETTE WILLIAM ROBERT
IPC: A61F13/511
Filed: 1996-12-27
Abstract: The present invention pertains, in a preferred embodiment, to a fluid-pervious web comprising a first or wearer-contacting surface and a second or garment-facing surface. The web is particularly well suited for use as a topsheet on a disposable absorbent article. The first and second surfaces are separated from one another by an intermediate portion. The first surface of the web provides a structure which exhibits a surface energy less than the surface energy of the intermediate portion. In a preferred embodiment, the web exhibits a plurality of regions of comparatively low surface energy which define surface energy gradients where they interface with higher surface energy web surfaces. More particularly, the present invention pertains to a fluid-pervious web having a plurality of small-scale surface energy gradients which are oriented and located so as to effectively transport fluid away from the first or wearer-contacting surface. The web essentially retains its visual, tactile, and physical properties of the substrate material while achieving the desired surface energy properties. Fluid transport webs according to the present invention preferably include discontinuous, spaced regions defining small scale surface energy gradients on the first surface to aid in small scale fluid movement toward apertures or capillary entrances for transport away from the first surface. Such webs also preferably include small scale surface energy gradients normal to the first surface within a capillary structure to aid in moving fluid away from the first surface and into the capillaries for capillary fluid transport. Web materials suitable for use in the present invention include apertured formed films, apertured and non-apertured nonwoven materials, composite structures, and the like.

Title: Improvements in electric clocks
IPC: G04B13/00
Filed: 1941-01-25
Abstract: 544,521. Electric clocks. HAYDON, A. W. Jan. 25, 1941. No. 1010. Convention date, Jan. 25, 1940. [Class 139] In motor-driven clocks of the type in which the numerals indicating time are carried by a series of rings, the rings which are rotatable independently are supported by means which are located a considerable distance from the centre line of the row of rings in order to permit the location of the motor and the other mechanism within the rings. The rings 7 .. 10, Fig. 9, are shown supported by three rods 11 .. 13 carried by the end plates of the case and the rings comprise an "hour" ring 7 having numerals zero to twelve, a "ten minute" ring 8 having two series of numerals zero to five, a "minute" ring 9 having numerals zero to nine and if desired a "seconds" ring 10 having numerals as shown. The rings are driven by palws 25, 26, 27, Fig. 7, carried by a shaft 28 mounted on an arm 35, Fig. 2, and oscillatable by means of a cam 38 driven by the motor and so arranged that the cam rotates once per minute depressing the shaft 28 until at the end of the rotation the spring 42 causes the shaft and consequently the pawls to give their working stroke. Fig. 4 shows the "minute" ring 9 which makes one revolution in 10 minutes, being intermittently rotated or advanced by the pawl 27 engaging the internal ratchet teeth 24 of the ring 9. The pawl 27 has a cam follower 30 connected to the pawl 26 and co-operating with the cam surface 29 of the ring so that the pawl 26 only engages the ratchet teeth of the "ten minute" ring 8 when the follower 30 enters the part 28J of the cam surface 29, i.e., in one part of the revolution of the minute ring. Similarly a cam follower 32 engages a cam surface on the "ten minute" ring 8 and is connected to the pawl 25 which engages the ratchet teeth of the "hour" ring 7 when the follower 32 enters the depression in the cam surface of the "ten minute" ring. The "seconds" ring 10 is continuously rotated by gear 40, 45, 44, 43, Fig. 2, from the motor. The numerals on the rings are readable through a transparent pane 47 of the window 6 in the clock casing. Specifications 392,405 and 426,242, [both in Group XXXV] are referred to.

Title: Improvements in or relating to nonreciprocal devices for electromagnetic wave energy
IPC: H01P1/365
Filed: 1961-01-10
Abstract: 958,270. Waveguide non-reciprocal devices: semi-conductor devices. WESTERN ELECTRIC CO. Inc. Jan. 10, 1961 [Feb. 3, 1960], No. 1011/61. Headings H1K and H1W. The wave-guiding structure of a non-reciprocal microwave transmission device is capacitatively loaded to reduce the phase-velocity of the guided wave to at least one-third that of free space. As shown in Fig. 1, waveguide 10 is loaded by an axially-extending slab 14, of e.g. TiO 2 , to either side of which are arranged elements 12, 13 of gyromagnetic material, e.g. ferrite or resin-bound garnet powder. The elements are subject to the field H<SP>1</SP> DC  of a horse-shoe magnet NS, the configuration of this field being such that it decreases in intensity from the centre of the waveguide, where the higher frequencies are concentrated, to the outer portions where the lower frequencies are propagated. Thus the field is related to the frequency to produce a non-reciprocal gyromagnetic effect over a broad frequency band. Non-reciprocal attenuation or phase-shift may be obtained. The effect of the dielectric loading is to distort the field in the manner shown in Fig. 2B, whereby the circularly-polarized magnetic field necessary to the gyromagnetic effect is produced over substantially the whole width of the guide. It is stated that, for a waveguide loaded in the manner shown, the condition for circular polarization at all points is where v and c are respectively the guided and free-space velocities of the wave. This condition is approximated by making v/c = <SP>1</SP>/ 3 . Since the field pattern shown can exist without conductive side boundaries, the narrow walls of the waveguide can be removed or they can be replaced by dissipative slabs 31, 32, Fig. 3, which have the effect of reducing spurious modes. In the construction of Fig. 3, capacitative loading is provided by spaced pins 35 which extend from the upper waveguide wall 33 almost to the lower wall. The gyromagnetic elements 11, 12 are positioned against the upper wall. In a modification (Fig. 4, not shown), the pins form the electrodes of junction diodes, the appropriate semi-conductive material being located in recesses in the wall 34. The junction capacity of the diodes must predominate over the inductance of the pin electrodes. A D.C. bias source for the diodes may be connected between the walls 33, 34, as shown in Fig. 5. In this latter construction use is made of a continuous strip diode comprising a knifeedged electrode 42 extending from the upper wall 33 and a continuous strip 43 of semiconductive material on the lower wall 34.

Abstract: 565,453. Cutting-machines for rubber tyres. MASCARENHAS, E. G. Jan. 25, 1944, No. 1412. Convention date, Jan. 25, 1943. [Class 31 (i)] Discarded rubber tyres 3, Fig. 1, are cut into strips by first splitting the cover medially by cutting along a helical line 1 and transversely at 2 between the ends of the. helix. The half cover 3 is slit into a continuous strip by mounting it on a wheel 4, Fig. 2, which is freely mounted on a horizontal axle 5 projecting from a spindle 6 cranked so as, to be offset relatively to bearings 7, 8 in which it is journalled to swing about a vertical axis 9 tangential to a circle located midway between the inner and outer peripheries of the half cover 3. A strip is cut, initially starting from the surface 2, and this is led to a pair of feeding rollers 18, 19, Fig. 4, which are driven by worm gearing 23, 24, Fig. 2, and belt gearing from a motor 11, which also operates a crank 13 for reciprocating a cutter 16. The cut strip 25, Fig. 4, is led over a guide 17 and the tension of the strip draws the cover 3 against an adjustable roller 26, the position of which determines the width of the strip. As the cutting proceeds, the arm 6 turns about the axis 9 so as to cause the wheel 4 to swing and maintain the cover 3 in contact with the roller 26. A disc cutter may replace the reciprocating cutter 16.

Title: Improvements in mine-laying submarines
IPC: B63G8/33
Filed: 1927-01-20
Abstract: 265.571. Wroczynski, Z. Feb. 2, 1926, [Convention date]. Laying mines.-A submarine vessel is provided aft of its resistant hull and outside the same with a compartment containing mines in horizontal rows or vertical columns and accessible to the sea water in submerged navigation. A mine compensation ballast tank u, Fig. 3, @is provided, or the usual ballast tanks are designed to give sufficient compensation for the loading and unloading of the compartment, and, if desired, also for annulling the weight of the compartment and the mechanism therein. When the mines are in horizontal rows, they are supported by rollers d, Fig. 9, in trackways formed by channelled rails c, and are moved along these rails by racks g on the mines driven by pinions i worked by a iointed shafting j. As a mine approaches the delivery orifice f beyond the rudders and propeller. its fore roller passes out of the channelled rail and back into it, and the rearroller moves through an enlargement n, Fig. 10, of the rail, while the mine swings round to fall out of the orifice. Several tracks may discharge through a single outlet. The mines are loaded into the compartment by means of a lift p, Fig. 11, and carriages q. A carriage with a mine thereon is moved transversely over rails s on to a lift p, which is then lowered to the level of the trackway to be loaded. The carriage is then moved transversely to bring the mine in line with the trackway; and, after the mine has been moved into the trackway by means of the rack and pinions, the carriage is taken back by the lift. The loading inlets and the discharge outlets may be provided with watertight doors, and watertight valves may be used to control the admission of expulsion of water to and from the mine compartment. When the mines are in vertical columns, they are supported and moved down to discharge outlets in front of the rudders and propeller by means of racks and pinions, the racks and pinions of each column being driven through bevel gearing by a single shaft. The discharge outlets may in this case be covered by non-watertight doors, which may be kept closed by a spring adapted to yield to the weight of a mine being launched.
