Filed: 1976-06-03
Abstract: A layer (21) formed from an absorbent material is pulled over a core (25) having a cavity (26) located on the end thereof and surrounded by a liquid-permeable, further layer (22). The two layers are moved by a device (27, 28) toward the end of the core (25), a piece of the liquid-permeable layer (22) which corresponds at least to the length of the future tampon projecting beyond the end of the core. An air jet nozzle (30), then presses this piece into the cavity (26), whilst the two layers (21, 22) move on and pull the bent end out of the cavity again. The entire structure moves through two cutting rollers (29) which cut the tampon thus formed to the appropriate length. In this way the absorbent material is located on exactly the right spot inside the tampon and is in the form of a gel (32) surrounded by two fabric layers (5, 6). <IMAGE>

Title: Improvements in or relating to radio beacon systems
IPC: G01S1/02
Filed: 1943-04-12
Abstract: 604,462. Automatic control systems. O'BRIEN, W. J. April 12, 1943, No. 23173/45. Convention date, April 13, 1942. Divided out of 579,170. [Class 38 (iv)] [Also in Group XL (c)] In a radio beacon system of the type described for example in Specifications 583,361, 584,727, or, 588,024, [all in Group XL], and 604,132, [Group XL (c)], the output from a receiver in the radiated field is employed to adjust automatically the phase relation between the signals in the spaced transmitting aerials for the purpose of correcting variations in the course line due to changes in the aerial characteristics. Spaced aerials A and B are excited from an oscillator 206 via lines 207, 208 and amplifiers and frequency multipliers 204, 205 so that harmonically-related frequencies are radiated and produce a desired equi-phase difference course line 200. Oscillator 206 is coupled to lines 207, 208 by tank circuits 235, 236 which are associated with a phaseshifting condenser 239, 240, 241 which is arranged to de-tune circuits 235, 236 in opposite directions so that the phase relation between the radio-frequency signals fed to aerials A and B, and thus the position of course line 200, may be adjusted as desired. The movable condenser element 239 is rotated by the reversible splitfield motor 242 under the control of a receiver R located on the extension 202 of the course line 200. The apparatus R comprises a doublechannel radio receiver 253 tuned to receive the signals from aerial A and B, followed by a phase discriminating apparatus 255 which produces zero output in coils 257 when a predetermined phase relation exists between the two received signals. When the phase relation departs from the desired value, contact 251 is moved under the control of operating coils 247, closing the circuit of motor 242 and causing the phase relation between signals from aerials A and B to be brought to the pre-determined value on the course line. The invention is also described as applied to an equi-signal type of beacon, Fig. 2 (not shown), which differs from the phasebeacon arrangement only in the provision of a motor driven switch.and phasing element in the connection between line 208 and amplifier 205 to produce the periodic reversal of the resultant radiation diagram from aerials A and B, the receiver R being also modified to respond to the overlapping beam signals.

Aug. 21, 1933, No. 23265. Convention date, Aug. 20, 1932. [Class 39 (ii).] Electric incandescent lamps connected in strings or festoons are provided with leading- in wires 12 which extend through the bulb and are connected at their ends to the ends of wires 16 which connect the lamps in series, the junction of the wires 12, 16 being enclosed in a plastic material which is moulded and hardened around a portion of the lamp bulb. Preferably the moulded material comprises a synthetic resin, for example either of those known under the Registered Trade Marks " Bakelite " and " Durite," together with a hardening-compound such as hexamethylenetetramine, and a non-compressible filler such as alumina, magnesia, silica, or marble flour. The connecting-wires 16 preferably consist of wire strands with an insulating covering 17, the ends of the strands being placed over or in contact with the ends 14 of the leading-in wires 12 which may be bent to extend at right-angles to the neck 13 of the bulb 10, the extreme ends of the conductors 16 being bent back to ensure a firm joint with the material of the moulded base 18. The arrangement is modified for double-ended elongated bulbs with a longitudinal filament connected to conductors secured in position by moulded material at each end of the bulb. The material is moulded upon the bulb by placing the neck within a two-part mould with the conductors extending through grooves provided therein, the plastic material then being inserted within a vertical passage and forced downwardly by a plunger, the mould subsequently being heated to set the materials.

Abstract: 715,681. Discharge apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 24, 1951 [Sept. 27, 1950], No. 23627/50. Class 39(1) In an electric discharge tube comprising a photo cathode and a perforated target of insulating material arranged adjacent to or on an electrically conducting signal electrode, the electron beam reproducing signals from the charge image on the target has a velocity so low that substantially no ionization is produced by interaction of the beam and residual gases in the tube giving greater persistence of charge image. An envelope 1 evacuated to 5.1-6 mm. of mercury contains a photo cathode 2 of photo-electric material, e.g. antimony-caesium on a conducting semi-transparent carrier and a target which may be insulating particles 3 of aluminium oxide, magnesium oxide or calcium fluoride spaced apart on a conducting plate 4, e.g. of aluminium. Alternatively the target may be an aluminium plate with discrete areas anodized; or a grid covered with insulating material as above in contact with or spaced from a conducting plate. The photo-cathode and target are arranged close together, e.g. 1 mm. apart. The end wall 6 is closely adjacent a magnetic core 5 of the re-entrant form and an energizing coil 7, a C.R.T. 8 produces a scanning light spot and a further C.R.T. 11 which may be a plan position indicator is disposed at the side and its image reflected by a mirror 10 on to the photo-cathode. Plate 4 is connected to the signal resistance 12, an amplifier 13 and a viewing C.R.T. 14; and the plate cathode 2 is connected via switch 15 to a voltage source 16. The plate 4 is 2 or 3 volts positive with respect to the photo-cathode and when the latter is scanned with the flying light spot, the particle 3 becomes stabilized at the potential of the plate cathode. Switch 15 is operated to reduce the potential of the photo-cathode by 3 or 4 volts, tube 8 is switched off and the optical image of tube 11 projected on to the photo-cathode causing particle 3 to become charged. This charge image is read on the tube 14 by operating the switch 15, to restore the original potential of the photo cathode and switch in the flying light spot of tube 8. The potentials used for the target and the photo cathode are not substantially greater and are preferably less than the ionization potential of the metals caesium, potassium, rubidium and sodium which are used in sensitizing the photo cathode. The target 4 is discharged by operating switch 15 to change the potential of the photo cathode to, for example, 100 volts negative. Scanning by light spot 8 releases electrons which discharge the target by secondary emission and bring the particles 3 to a potential of a few volts positive. The potential of the photo cathode is then brought to zero volts and again scanned.
