Abstract: 1,124,243. Tampons. DR. CARL HAHN KG. @9 Nov., 1965 [2 Dec., 1964; 31 Dec., 1964 No. 50616/65. Heading A5R. A cylindrical catamenial tampon formed by winding up and pressing a fibrous fleece is characterised in that the material of the fleece is inhomogeneously distributed along the axis of the tampon so that the tampon is divided longitudinally into zones 7, 8 having alternately large and small densities of material, the zones constituting expansion and adsorption zones respectively. In particular the tampon may be formed by winding up a fleece of cotton fibres or regenerated cellulose fibres, or a mixture of these, on which are elongated elevated portions (Figures 8, 9, not shown) of regenerated cellulose, cotton, porous plastics material, or natural or synthetic fibrous material, the elevated portions forming the expansion zones in the completed tampon. The expansion and adsorption zones may be inclined across the axis of the tampon (Figure 4, not shown) and tufts 6 of fibres may be drawn transversely through the adsorption zones 8. The tampon may be enclosed in a net.

Title: Dual slope type resistance deviation measuring apparatus

Filed: 1973-11-01
Abstract: 1388100 Digitizing resistance differences YOKOGAWA ELECTRIC WORKS Ltd 1 Nov 1973 [15 Nov 1972] 50824/73 Heading G4H A dual romp analogue to digital converter is used to measure the difference between two resistances by passing the same current through each resistance, using the voltage across the resistances to generate the up and down romp respectively and digitizing the time duration by which the down romp exceeds the up romp. If one resistor is fixed and the other a temperature dependent sensor the device can measure temperature. As shown, a temperature dependent resistor Rt and a fixed resistor Rs having the value of Rt at 0 C. are connected in series so that current from battery E flows through them. Switch S is moved to position 1 for a time Tc determined by generator TM generating the up romp at the output of the integrator comprising A, C and R 2 . Switch S is then moved to position 2 applying a reference voltage of opposite polarity to the integrator (the junction of Rt and Rs being a common point). After a time Tc of the down romp, counter M is enabled and the duration of the remainder of the down romp, until its termination is signalled by threshold circuit H, is digitized.

Abstract: 509,514. Two-stroke engines ; valves. LUND, O., and PETERSEN. O. Feb: 10, 1938, No. 4247. [Classes 7 (ii) and 7 (vi)] In a two-stroke engine supplied with supercharging-air admitted by a positively controlled valve after scavenging, the supply of scavenging-air at a lower pressure than that used for supercharging is also controlled by a positively controlled valve. Fig. 3 shows one arrangement of valves for controlling th supply of scavenging - air from a chamber 1 to piston-controlled cylinder ports 6, 7, and the supply of supercharging-air from a chamber 4 to the ports 7. The valve 5 controlling the latter supply is double-seated, so as to shut off the scavenging-air when opening the supercharging inlet, the supply of scavenging-air being controlled by a valve 3. In a modification, the valve 5 is in the form of a piston valve attached to the valve 3.

Title: Gridded retarding field electron diffraction spectrometers

IPC: H01J37/295
Filed: 1969-10-17
Abstract: 1277466 Electron microscopes VARIAN ASSOCIATES 17 Oct 1969 [21 Oct 1968] 51146/69 Heading HID In an electron diffraction apparatus comprising means such as the guns 2 and 2<SP>1</SP> for directing a stream of mono-energetic electrons on to a target 1, a spherical fluorescent screen 3 for displaying a diffraction pattern and concentric spherical grids 5<SP>1</SP> and 9, the resolution is improved by preventing field penetration of the retarding grid 5<SP>1</SP> and by making the radius of the earthed grid 9 between 30% and 80% of that of grid 51 instead of at least 95% as hitherto. The grid 5<SP>1</SP> may comprise two concentric grids, as shown in Fig. 3, separated radially by at least one third the distance between grid wires; alternatively it may comprise a metallic cellular structure having passageways of a diameter less than three times their length. An earthed grid 11 may be provided adjacent the screen 3 to reflect secondary electrons emitted by the screen, and spherical electrodes 26 and 27 are placed at the edges of grid 9 and provided with intermediate potentials to preserve the shape of the equipotentials in the marginal areas. When observing inelastically scattered electrons produced by the impact of electrons from the oblique gun 2 operated at - 100 volts, the voltage of the retarding electrode 5 may be swept synchronously with a recorder and modulated by 1 volt at 100 Hz., the current collected from the electrode being fed through a phasesensitive detector to the recorder (Fig. 1, not shown). The second input of the phase-sensitive detector may be the modulation signal, or the second harmonic of the modulation signal derived by feeding the signal through a diode multiplier; in the latter case the output of the detector corresponds to the first derivative of the energy distribution. When observing elastically scattered electrons the gun 2<SP>1</SP> is used; since its outer tube 28<SP>1</SP> is connected to the innermost grid 5<SP>1</SP> the latter is then unable to operate as a retarding grid, but the grid 11 in conjunction with the outermost grid 5<SP>1</SP> may be used for the retarding system. The fluorescent screen 3 is observed through a window (not shown) disposed to the left of the target 1.

A switch for testing specific gravity or the level of liquids comprises two weights 57, 58 suspended from opposite ends of a pivoted member 55 and of different densities such that, although of different sizes, they normally balance. Weight 57 moves in oil 61 in a tube 51 and has a magnet 59 which closes switch 75 when lowered, due, for example, to weight 58 becoming immersed in water. The device is enclosed in a cylindrical housing 22 secured on a tube 11 for lowering down a bore-hole, for example. Two such devices may be provided in tandem (Fig. 1, not shown), and their switch contacts arranged in series so that a circuit to a pump, for example, is not completed until both are immersed. By use of a relay and a resistor across the contacts of the upper switch (Fig. 7, not shown) it may be arranged that the pump circuit is maintained until both switches are opened.

Abstract: 1532440 Adaptive equalizers FUJITSU Ltd 23 Dec 1975 [27 Dec 1974] 52753/75 Heading H4R In an adaptive transversal equalizer residual phase distortion at the output of the equalizer is detected and compensation signals derived which are used to modify the transversal equalizer output to compensate the residual phase distortion. As described the output of the transversal filter at 5 is fed through a multiplier 13 to a detector 6 to produce the final output a (#). Difference circuit 7 connected across the detector 6 provides an error signal output E(t) which in the processing circuits 14 to 18 produce a phase change signal CAPC which, applied to multiplier 13, modifies the phase of the filter output to reduce phase errors therein. The phase change signal CAPC is also applied to multiplier 12 to modify the error signal fed back to the adjustment circuits of the transversal filter. The phase change signal CAPC derived by the circuits 14 to 18 can follow more rapid changes in phase shift in the signal than the transversal filter and can therefore compensate for phase filter or frequency shift. An arrangement for implementing the equalizer digitally, using registers to provide the delays, is described with reference to Fig. 3 (not shown), and the detector 6 is described with reference to Fig. 5 (not shown).
