Patent GB-1095656-A (GB)
Title: Nonwoven fabrics and methods of making them
Inventor: SANDERS ARTHUR JOSEPH
IPC: D04H1/48
Filed: 1964-09-08
Abstract: A nonwoven fabric comprises three super-imposed fibrous layers, the fibres constituting the central layer being different from the crimped fibres which constitute at least a major proportion of the fibrous outer layers, and the central layer being keyed in position by needled fibres which extend in the thickness direction of the fabric from at least one of the outer layers to the opposite outer layer and which project beyond the face of the opposite outer layer as crimped fibre tufts.  The fabric is made by superimposing the three fibrous layers, needle-punching the fibres in either or both of the outer layers through the central layer and the opposite outer layer so that they extend beyond the face of one or both outer layers as tufts, and subjecting the needle-punched structure to a treatment to crimp the crimpable fibres forming the major proportion of the outer layers.  The crimpable fibres of the outer layers are of polyamides, polyesters, or polypropylene, or are polyhexamethylene adipamide polyepsilon caprolactam or polyhexamethylene adipamide polyomegaaminoundecanoic acid or polyhexamethylene adipamide/polyhexamethylene adipamide-polyepsilon caprolactam copolymer composite fibres, or composite fibres based on polyesteramides, polyesters, polyhydrocarbons or polyurethanes. The central layer is composed of fibres which are crimped before the needling operation, or of inert fibres, e.g. viscose rayon, ceramic, glass, and cellulose triacetate, and may include a loosely woven scrim.  The outer layer fibres may be bonded by impregnation with natural or synthetic resin, or by the inclusion therein of synthetic resin powder or thermoplastic fibres which are subsequently activated, or when the fibres of the outer layers are composite fibres, by including a potentially adhesive material as one of the composite fibre components.  The crimping of the fibres, and the bonding when present, is/are effected by a chemical medium or by heat, optionally with pressure, e.g. in an oven or by immersion in boiling water, and when both treatments are present they may be effected simultaneously.  The central layer may be of absorbent material, e.g. cotton, in which case the fabric is useful as surgical dressings, sanitary napkins or diapers, towelling, wiping cloths, or filter material.

Abstract: 1,030,074. Substation circuit. SIEMENS & HALSKE A.G. Sept. 9, 1964 [Sept. 11, 1963], No. 36870/64. Headings H3T and H4K. [Also in Division G1] In a push-button telephone subscriber station an audio signal is given after a button has been actuated to confirm the operation of the associated digit signalling components. In one arrangement shown in Fig. 1, each button is a variable capacitor SKI ... SKn such that when the operators' finger is placed upon it the reactance falls and allows the associated glow discharge tube Gl1 ... Gln to ignite; the subsequent drop in resistance of the photosensitive resistor F1 . . . Fn actuates the digit switching relays A1 . . . An. The voltage across R2 delivered through the differentiating circuit C, D, produces a short audible signal in the station signal device T, which is connected to the keyboard on raising the switch hook contacts W1, W2. In a second arrangement, having a normal push-button keyboard (Fig. 2), the audible signal is produced by the amplifier in the subscriber station which is made to oscillate each time a button is pressed by shunting the negative feedback resistor R GK  by the tuned circuit C1, L1 as the Zener diode Z breaks down. The oscillations are monitored through the receiver H and their frequency is determined by C1, L1. The break-down voltage to the diode is applied from button contacts a1 ... a0 through a differentiating circuit C D , to produce only a short signal. The buttons also actuate the digit signal relays A1 . . . A0. With no button pressed the combined effect of the negative feedback from R GK  and the positive from R MK  produces no oscillations and the speech signals are amplified in the normal way.

Title: Improvements in or relating to means for sealing and centering a piston in a gas holder
IPC: F17B1/013
Filed: 1957-12-03
Abstract: 908,989. Gas holders. BINMORE, J. M. Feb. 13, 1959 [Dec. 3, 1957], No. 37561/57. Class 54. For sealing and centring the piston 1 of a gas holder, annular peripheral chambers 10 at the top and bottom of the piston are closed by flexible rings 3, 4 having rubbing rings 8 and the chambers are divided into six compartments 11 by flexible partitions 9, each compartment being in communication with a header tank 13 to provide a liquid head which maintains the rings in engagement with the wall of the holder. Each of the tanks 13 is formed by two compartments 14, 15 connected by a conduit 16 so that, if the tanks are filled halfway up the conduit when the piston is level, any tilting of the piston will cause rapid increases or decreases of head in the tanks to which liquid is forced or from which liquid is drawn. The header tanks are connected in diametrally-opposite pairs to float chambers 17 in which floats 18 are connected to a lever 19 controlling a master filling valve which opens if the level in both float chambers falls below the mean level; this will happen if there is leakage affecting one header tank, as tilting of the piston will lower the level in the diametrally-opposite tank. The lowering of the level in a make-up tank 20 may give an alarm. Alternatively, a gauge glass side-by-side with a gauge glass connected to the header tank may be connected by a liquid column to a cylinder having a piston linked to a roller bearing on the gas-holder wall. To prevent water hammer, the conduit 16 in the header tanks may be carried a short distance below the top of the lower compartment 13, to provide an air lock or an air vessel may be provided at the top of each chamber 10 in the conduit from the header tank. The space 8A between the rubbing rings 8 may be supplied with lubricant under pressure and loose segments 29 of hard material may be fitted in the spaces 8A to prevent tripping of the rings 8. A fringe of springs 30 secure the rings 3 to angle members 5, 6 and engage the top and bottom rings 8 to relieve the rings 3 of the force necessary to take the rubbing rings upon and down with the piston. The rings 3, 4 and 8 may be made from rubber or synthetic rubber reinforced, if necessary, by fibrous laminates.

Title: Process for displaying a physical event such as a seismic event
IPC: G01D9/00
Filed: 1970-08-04
Abstract: 1322379 Graphical exploration MARATHON OIL CO 4 Aug 1970 [26 Jan 1970] 37619/70 Heading H4D An electrical signal representing a physical event over an interval of time is displayed by separating the signal into a plurality of filtered signals each representing the component of said signal in a respective band of a continuouslyvarying parameter, converting each filtered signal into a respective visible line having excursions the frequency of which represents the intensity of the signal in said respective band of the parameter, producing a differently coloured replica of each line, and combining the coloured replicas to form a single display indicative of the parameter component distribution of the electrical signal. The electrical signal may be derived from geophones, from devices for borehole echo-ranging or radiation logging or well bore acoustical logging, from resistivity electrodes for electrical prospecting, or from precession magnetometers. The said parameter is e.g. frequency, seismic velocity, or velocity gradient. In the Fig. 1 embodiment analogue or digital recordings of the outputs of geophones 1 are made at 3 then fed to computer 4 where they are subjected to static and dynamic time corrections, band-pass filtered to remove noise, deconvolved and stacked. The resulting signals are separated by filters 5, 6, 7 into the frequency bands 5-30 Hz, 30-55 Hz, and 55-80 Hz. Filter 5 output is processed by computers 8, 9, 10 respectively programmed to rectify the signals, derive the envelope of the rectified signal, and convert the amplitude of the envelope signal into a proportional number of short vertical excursions of the pen of plotter 11. A black and white negative of the plotter record is made by camera 12 then is converted by printer 13 to a singlecoloured transparency E. Similar transparencies E<SP>1</SP>, E<SP>11</SP> (with different respective colours) are derived from the outputs of filters 6 and 7. A black and white variable area plot of computer 4 output is made at 15 and converted by camera 16 to a black and white negative transparency A. The four transparencies are viewed in superposition. Modifications:-(1) A multiple-projector technique is used for projecting transparencies or opaque representations of the filtered signals on to a screen, with a differently coloured image for each signal. (2) Spaced polarized projectors are used with polarized viewing glasses to display additional variables e.g. topography in a seismic section displayed stereoscopically such that the three dimensions represent respectively distance along the ground, time and signal amplitude and such that the display colour represents frequency. (3) The three filtered signals are connected to respective colour guns of a three-gun cathode ray tube. (4) The filtered signals are displayed by dye-transfer matrix techniques of photography.

Title: Improvements in tensioning means for endless conveyors
IPC: B65G23/44
Filed: 1956-12-18
Abstract: 793,229. Endless conveyers. STAHLWERKE BRUNINGHAUS GES. Dec. 18, 1956 [Jan. 19, 1956], No. 38581/56. Class 78 (1). An endless belt or chain conveyer includes hydraulically acting tensioning means provided with an hydraulic pressure-sensitive device adapted to switch off the drive of the conveyers and if necessary associated components, when a permissible tractive force in the belt or chain is exceeded. As shown, a conveyer belt 17 passes over a driving drum driven by a motor 10 and a tensioning drum carried by slidable bearings secured to the piston rods of a pair of cylinders 4 in which hydraulic fluid is adapted to be maintained at a predetermined pressure. In the form shown in Fig. 1 this is accomplished by a pressure-sensitive switch 6 controlling the motor 7 of a pump 1 for the hydraulic fluid. A non-return valve 3 prevents fluid returning from cylinders 4 and provides means whereby an increase in tractive force in the belt causes a rise in the pressure of hydraulic fluid which when excessive actuates a spring-controlled piston 8 acting on a switch 9 to cut off motor 10. In an alternative form, Fig. 3, the motor 7 is driven continuously to circulate hydraulic fluid through a pressure relief valve 11 and instead of a spring-loaded piston, a double piston 14, 16 is provided which is moved to actuate the switch 9 when the pressure in cylinders 4 exceeds the setting of an adjustable pressure relief valve 12. This movement of the pistons 14, 16 connects to the cylinders 4 to a conduit 15 relieving them of pressure, and actuates switch 9 to switch off both of the motors 7, 10.
