Title: Disposable diaper with tape fastener having a release liner which also provides a means to grip and remove the topsheet
IPC: A61F13/58
Filed: 1973-10-16
Abstract: 1444433 Diapers PROCTER & GAMBLE CO 16 Oct 1973 [16 Oct 1972] 48100/73 Heading A5R A disposable diaper consists of a liquid retaining backsheet 11, superposed on it a liquid absorbent pad 13, which can be made of creped paper or wood pulp, a releasably secured liquid pervious, and preferably hydrophobic, top sheet 16, and a pressure sensitive tape 22 which has its portion 22a attached to the underside of the backsheet 11 whereas the portion 22b is releasably held to a release liner having segments 23a and 23b, the release liner being so attached to a central separable portion 17 of the top sheet 16 that after use the portion 17 can be separated from the diaper by pulling the liner. Portions 11a and 11b of the backsheet wrap around the edges 12 and 12' of the pad to provide barriers against the wicking of liquid wastes. The removable portion 17 of the top sheet is defined by a line of weakness comprising perforations (18) and cuts 19 whereas the peripheral area 20 of the top sheet is attached to a sheet 15, which together with a sheet 14 encases the wood pulp, by liquid insoluble adhesives applied in the region 21. The segment 23a of the release liner, which extends around the edge of the diaper, is secured to the portion 11a by a suitable adhesive 26 whereas the portion 23b of the release liner extends beyond the portion 11a and overlies a portion of the removable sheet 17, being secured thereto by a strong adhesive bond in the region 24. The portion 23b is essentially unsecured to the portion 11a by means of coloured tab 25 fixed to the face of the release liner distant from the tape. In a modification of the release liner, the tab 25, which is in the form of a thin film with its "grain" oriented across the width of the tape, extends around the edge of the diaper so that when the tape portion (22b') is peeled from the release liner (23b'), the film is torn along the grain.

Title: Azimuth alignment system
IPC: G01D5/38
Filed: 1966-10-27
Abstract: 1,145,813. Photo-electric direction indication. GENERAL PRECISIONS SYSTEMS Inc. Oct. 27, 1966 [Nov.1, 1965], No.48323/66. Heading G1A. [Also in Division H4] Photo-electric apparatus is used for aligning, calibrating or adjusting a direction indicating device, such as the compass system of an aircraft, with respect to a reference object which is remote from the apparatus and aligned in a known direction. The reference object is a pattern 10, of parallel strips alternately black and white, light from which is focused by the lens system of the apparatus to form an image on a film-strip 30, which itself bears a pattern of alternate opaque and transparent strips. The film is moved in the plane of the image by motor 36 to vary the amount of light falling on a photo-multiplier 31. The output of the latter is then used to rotate through motor 46 the whole apparatus in accordance with the degree of misalignment of the image with the film-strip pattern. In the final position of the apparatus, the zero arrow 19' of disc 45, is aligned with the known direction given by pattern 10. The pattern on the film is comprised of sections in which the strips are offset to the normal. The strips of alternate sections are parallel to one another and those of adjacent sections offset equally in different directions, Fig. 2 (not shown). Thus, if the normal of the film-strip is aligned with the strips of the image of the pattern 10, (i.e. the sections of the film pattern are equally offset with respect to image) the output of the photo-multiplier 10 is a regular A. C. wave, having a constant envelope, Fig. 7D (not shown). Any misalignment of the film pattern with respect to the image (e. g. such that the strips in one set of sections are parallel with the strips of the image, the strips in the other set being offset at a large angle to those of the image) results in an irregular A. C. wave having a squarewave envelope, Figs.78, C (not shown). A phase detector (62) receives the detected envelope signal and also keying signals from a photo-electric system 50, 51, which detects the changes from section to section in the filmstrip pattern. The D. C. output of the phase detector is integrated (63), amplified and used to drive motor 46. The integrated signal may also be metered (64) to indicate the direction of rotation of the motor. There is provision in the circuit for regaining a photo-multiplier output if this disappears due to too great a misalignment between film pattern and image. The apparatus can be mounted on an aircraft chassis to detect a pattern 10 on the ground before take off or, by use of a zoom lens, during flight. Linkage from the disc 45 may be provided to an indicator remotely located with respect to the photo-electric apparatus.

Abstract: 1,169,829. Digital indication of liquid level. ROSEMOUNT ENG. CO. Ltd. 18 July, 1968 [25 Oct., 1967], No. 48443/67. Heading G4H. An indicator for showing the level of a conductive liquid, e.g. sea-water, comprises a common electrode 10 and a series of vertically spaced electrodes 11, 12, 13 &c. which are connected together in groups to pairs of output leads, there being means to detect an equality or difference in the conductances of the leads of each pair. The lead A is connected through resistors 21, to electrodes 11, 15, 19, 23 &c. and lead B is connected to intermediate electrodes 13, 17, 21 &c. The leads A and B are connected to the centre-tapped secondary winding of a transformer. If the conductances at the two leads are equal currents in the two halves of the winding are balanced, and there is no output at the tapping. If they are different an output is produced. This binary bit if a " 1 " therefore indicates that only the lower one of a pair of electrodes, e.g. 11 and 13 is immersed. The next pair of output leads C, D gives a coarser indication, the pairs of electrodes connected to them being more widely spaced. The signal from output leads E, F indicates whether the level is in the central zone, and the outputs from leads 37, 38 indicate whether the level is in the upper or lower half. The output in leads 39, 40 indicate whether or not the top electrode is immersed. The electrodes may be copper bars protruding from a bonded plastic body containing the resistors 21 and the output conductors 31-40. The electrodes co-operate with an elongated metal object serving both as the common electrode and as a support for the electrode assembly.

Abstract: 1,222,826. Washing machines. BRITISH DOMESTIC APPLIANCES Ltd. 24 Oct., 1968 [25 Oct., 1967], No. 48533/67. Heading D1A. [Also in Division F2] A rotary drum washing machine comprises an automatic sequence control, an interlock arranged to prevent opening of a door giving access to the drum except after certain operations have been completed manually operable means for by-passing at least one operation, and time delay means which prevent release of the interlock for a time sufficient to prevent opening of the door until a safe period has been reached. A spring-pressed door latch 49, Fig. 9, is adapted to be released by a Bowden cable 45 and pivoted lever 43 on actuation of a push-button 47 after the expiry of the safe period. A toothed disc 8 in a sequence tmer 1 has an upstanding wall 8a with a gap 8b which allows pivotal movement of a member 36, connected to lever 43 by links .39, 42, only after the final operation has been completed. The disc 8 is mounted on a shaft 5 which is driven in successive steps, conveniently at two minute intervals, from a synchronous electric motor 2. The shaft 5 also carries a face cam 6 which selectively energises and de-energises various electrical components of the machine. A lever 13 is pivotally mounted on a pin 14 secured to the underside of disc 8. A projection 16 on lever 13 passes through a slot 17 in the disc 8 and is adapted to be engaged by one of four projections 10a of a manual control knob 10 rotatably mounted on the shaft 5, by means of which control knob the programme may be advanced. The lever 13 carries a projection 18 which is urged by a spring 15 into engagement with the inner surface of an annular cam 19. Two steps, or four minutes before the end of the programme the projection 18 enters a cam recess 19b causing the projection 16 to move out of the path of the projections 10a so that by-passing of the final stage, during which deenergisation of the driving motor, coacting of the drum to a halt, and energisation of a drain pump occur, is not possible. A programme indicating pointer 25 is driven by a cord 24 which passes around a drum 26 integral with a gear wheel 20 driven from the toothed disc 8. The machine is started by pulling knob 10 outwards in order to close an isolating switch to supply electrical power to the timer motor 2. Further gaps may be provided in the wall 8a to permit the access door to be opened at various other points in the programme.
