In a first process, Fig. 1, a web 1 of nonwoven material is passed over a heated roll 4 which gives a smooth surface to upper side 7 of the web, embossing rollers 9, 10 then compress the web leaving pad portions 15 upstanding on the upper side of the web. Medicament is applied to the underside of pad portions 15 by rollers 19-21 and are dried in oven 25. Adhesive 25 is applied to the under side of tab portions (8) of the bandages by rollers 26-28. Removable backing papers 30, 31 are applied by rollers 32, 33. The treated web is cut into strips by knives 34, 35 and the strips are then rolled up. Knives 36, 37 may be used to cut short lengths or individual dressings from the web or strips. In a second process Fig. 8 (not shown), generally similar to the first process, an embossing roller is used to produce an absorbent pad which protrudes from the underside of the web. In a further process (not shown), a flat bed platen press embosses the web and adhesive is applied by a flat bed printing press. One embodiment of bandage Fig. 4 (not shown), has tab portions with embossed ribs. Bandages may be made with several pad portions. The web may be made of a variety of hydrophobic thermoplastic fibres.

Abstract: 1,214,655. Electroluminescence. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 19 Dec., 1967 [21 Dec., 1966 (2)], No. 57575/67. HeadingC4S. An e.1. diode comprises an e.c. crystal having a flat junction 3 intersecting side faces 4 arranged at angles to the crystal axis such that all normals to the faces in the immediate vicinity of the junction extend from the surface on one side of the junction, the crystal having a strong refractive index gradient normal to the juncjunction such that radiation is guided along the plane of the junction and emanates mostly through surfaces adjacent the intersection of the junction and faces 4. A frusto-conical Zn diffusion doped GaAs crystal has Cu contacts 5, 6 soldered to its flat surfaces, contact 6 acting as a heat sink. The crystal has its apex angle A greater than the critical angle so that radiation from the junction emerges only from the region 1 which has n-type conductivity with a low free charge. This passes only a narrow spectrum of radiation but has a high tranmission. If a wide spectrum is required the apex angle is reduced allowing light from both sides of the junction to emerge and electrode 5 is replaced by a metal ring around the conical face which permits radiation to emerge from the end face 7. Projectors may comprise a frusto-conical crystal in the focal plane of a paraboloidal mirror or a pyramidal diode and a parabolic mirror, an ellipsoid mirror is referred to. The crystal may be surrounded by air liquid or solid. The crystal need not be a body of revolution or symmetrical and the section shown of the diode may be curved except near the junction.

Patent GB-600446-A (GB)
Abstract: 600,446. Cash registers. GROSS, H., and GROSS, S. Jan. 1, 1946, No. 39. [Class 106 (i)] A cash register or other calculating machine comprises means whereby operation of one or more actuating keys releases corresponding levers, arranged front to rear of the machine, so that all released levers move under spring action to positions in which they can be engaged by a coupler device, and other means whereby mechanical power is available when all the keys are in unreleased position, said power actuating the coupler device when one or more keys are operated fully, so as to complete the movements of the released levers to actuate the calculating mechanism. The keys 20 are arranged in denominational banks, partial depression of a key causing a resilient presetting pawl 32 or 33 to hook over a shoulder on the depressed key. A hook 60 on each depressed key also releases a hook 59 on an associated lever 58 which rocks slightly under the action of a spring 63 to engage a hook 61 over the edge of a coupler bar 64. Full depression of a key rocks a trip bar 81 and levers 82 which rock a pawl 80 clockwise to release a cam track lever 70 which is then rocked clockwise about its pivot 71 by a strong spring 73. A cam slot 69 lifts a roller 68 to lift the coupler bar 64 so that the selected levers 58 perform a full counterclockwise movement with the bar 64, cams 62 on the levers actuating the appropriate denominations of a totalizer through gear sections 94. The lever 70 opens the drawer through a roller 72 and a cam slot 75. Opening the drawer lifts a roller 46 to rock levers 43 clockwise to hold the pre-setting pawls and therefore the keys against displacement. The subsequent closing of the drawer retensions the actuating spring 73, while an abutment 51 rocks a spring-pressed pawl 49 to rock the levers 43 counter-clockwise, T-shaped members 41, 42 on the levers 43 pulling the pre-setting pawls counter-clockwise to release all the keys. The spring-pressed pawl 49 finally engages an abutment 50 to hold the levers 43 just clear of the pre-setting pawls. A toothed segment 76, Fig. 3, and a spring-pressed pawl 77 form a full-stroke device. Keys depressed in error can be released by depressing a key 53 which rocks the levers 43 to withdraw the pre-setting pawls. The actuating spring 73 may be supplemented by or replaced by an electric motor controlled by a switch operated by the part 80 or -82. A lock 100 can be operated to lock the drawer by locking the lever 82, Fig. 5. Each bank of keys has a crowding ball or rod lock. Specification 600,449 is referred to.

Abstract: 1,221,479. Time switches. F. R. HORMANN. 19 Dec., 1968, No. 60442/68. Heading HlN. A circuit interrupter with automatic programme variation, for use in a lighting circuit, for example, as a burglary deterrent, comprises at least two cams one of which is driven by an electric motor via speed-reducing gear and the other of which is coupled to rotate in a set relationship with the first, means being provided for altering the set relationship at least once per revolution, and a cam follower controlling switch contacts in accordance with the combined profile of the cams. As shown, a synchronous motor 14 drives a cam 21 fixed on shaft 17, and further cams such as 25, loose on shaft 17, are urged towards cam 21 by spring 27 with the interposition of friction discs 22, 24. A follower 28 is actuated by the combined profiles of the cams and operates a change-over microswitch (31, Fig. 4, not shown). Cam 21 is rotated once in 4 to 5 hours, for example, and an arm 45 thereon engages an arm 42, which is guided for axial movement in a fixed bush (44, Fig. 3, not shown), once per revolution. Arm 42 acts on collar 39 to move cam 25 to the right, thereby releasing the frictional coupling to cam 21 for a short time such that a small relative motion occurs between cams 21 and 25 and their resultant profile combination is altered. An additional Y-shaped cam (23, Figs. 2, 3 and 6, not shown) may be loosely carried between friction discs 22 and 24 such that it swings under gravity when the coupling is released and further complicates the irregularity of the profile pattern actuating follower 28. The profile pattern may also be altered in an uncontrolled manner at any time by holding back the collar 39 manualy for a short period.
