Patent GB-1066437-A (GB)
Title: Iodophors
Inventor: EVANS DEREK ANTHONY
IPC: C11D1/00
Filed: 1963-10-29
Abstract: An iodophor comprises iodine dissolved in a water-soluble, non-ionic, surface active agent consisting of a polyoxyethylated polyoxyalkylated alkyl phenol wherein the polyoxyalkyl group comprises oxyalkylene groups having 3 or more carbon atoms.  The polyoxyethylated polyoxyalkylated side chain of the surface active agent may have the formula:  <FORM:1066437/A5-A6/1> wherein n and m are from 1-50 and A is an alkylene chain of 3 or 4 carbon atoms, and octyl or nonyl groups may be present in the para-position on the benzene ring with regard to the above side chain when the other substituents on the benzene ring are hydrogen atoms or hydrogen atoms and one methyl group.  The iodophor may be stabilized by admixture with a quarternary ammonium compound of a diamine with a halogen compound as described in Specification 923,114.  The stabilized iodophor may be further modified by the addition of a solubilization agent (e.g. ethylene glycol monoalkyl ether) and a buffer such as phosphoric acid.

Locking means such as tongue-and-slot connections as shown in Fig. 5 or gusset folds are provided at each of the lateral edges of the frame forming panels to secure them in the inwardly extending position to simulate the appearance of a solid frame around the periphery of the article. Two sets of frame edge forming panels may be provided on opposite edges of each wall panel to provide two oppositely directed display openings. Alternatively, the display device may be a separate lid slid on to a tray-like box as in Fig. 2. The invention may be applied to a onepiece carton in which a base panel is foldably and integrally connected to a free edge of one wall panel, the remaining opposite pair of wall panels having flaps foldably connected thereto which engage on the inner face of the base panel and a tuck-in flap being connected to the base panel so as to engage with the inner face of the remaining wall of the carton. The base panel may be formed from extensions on two opposite wall panels, said extensions being joined together by a locking means such as a tongue-and-slot arrangement.

In the melting of particles 10 of quartz or glass, they are introduced through one or more feed devices 9 in a lower closure 8 to a refractory container 1 containing a heat carrier 4 consisting of molten metal or alloy so that the particles pass substantially vertically through the heat carrier by virtue of their lower specific gravity, the heat carrier 4 being heated as by an induction winding 12 or electrically or combustion heat or a combination so as to give off heat to the quartz or glass particles to melt them, the resultant molten glass 11 settling above the heat carrier 4 in a collecting chamber 7. The molten glass or quartz may then be drawn off through a die 13 and eooling deviee 14 in the form of a rod or tube 15. In a modification, the chamber 7 is open-topped and the molten quartz or glass 11 passes in a thin layer over the heated top edge (18) with one or more side units (19) where further processing and heating (20) may be given. Foamed quartz or glass may be formed either by incorporating gas producing materials, in the particles or in a modified apparatus in which gas bubbles are, produced from a dispensing device in the lower closure, or both methods may be used.

IPC: G03C7/14
Abstract: 447,917. Copying lenticular film records. 1. G. FARBENINDUSTRIE AKT.- GES., Frankfort-on-Main, Germany. Nov. 27, 1934, No. 34080. Convention date, Nov. 28, 1933. [Class 98 (ii)] The differences in brightness in the printed picture due to the optica system used in ex posing the origina lenticular film or in the printing process are com pensated for by interposing a com pensating screen between the source of light and the sensitive surface during printing. The screen may be produced by hand or by a photographic method consisting of exposing a lenticular screen film to a uniform grey field under conditions similar to those of taking or reproducing the lenticular film to be copied. In the case where the colour-record components are produced on separate layers by arranging reflectors in the path of light from the lateral components, individual screens are used for each component. The Figure shows one method of preparing the screens. The sensitive surface A<1> B<1>, C<1>, D<1> is exposed to a uniformly illuminated white or grey sheet A, B, C, D using the projection objective O with a mask having an aperture corresponding to one of the strips of the colour band filter. The shaded portion indicates the inequalities of brightness produced by the objective O. The Specification as open to inspection under Sect. 91 describes also arrangements in which the screen is situated between the light source and the original or in front of the sensitive surface during projection printing and is arranged between the two films during contact printing. This subject-matter does not appear in the Specification as accepted.

The point extremity is blunted for strength. As shown, there may be a second low thread 44 but there may be three or more threads of different heights. The height of a thread may vary in some turns. The screw shank may have a taper and the thread turns need not be spaced with shank surface between, as shown. The leading end may be slotted to provide a cutting edge.

Abstract: 1473849 Glow discharge lamp; gas discharge display panel MULLARD Ltd 3 July 1974 [28 Sept 1973] 45522/73 Heading H1D In a gas (e.g. Ne) filled D.C. glow discharge display panel with transparent window 9 sealed to insulating base 1, anode wires 10 forming columns of an array oppose discrete unshielded areas under cavities 3 of cathode metal strips 2 forming rows, enabling a discharge to be struck in a cavity 3 at any address: each element of the array must then have sufficiently high differential resistance in the discharge part of its V-I characteristic (Fig. 1, not shown) to limit the current to a safe value; rather than add individual resistors the characteristic is modified by coating the exposed cathode strips with a thick layer of carbon, preferably finely divided C such as carbon black or colloidal graphite, possibly with Na or K silicate bond; the carbon may be admixed with SiC, B 3 C 4  or with alumina or glass powder: alternatively baked carbon of "Papyex" (Registered Trade Mark) carbon paper may be used. Carbon is chosen for its resistance to sputtering: grooves 5 across the ribs 4 of block 1 also prevent crossconnection due to sputtered material. Auxiliary coated cathodes 6 at each end exposed along their whole length to the ends of successive anode wires 10 provide a continuous discharge as a source of ionization to assist starting of the cavity discharges. In an alternative embodiment (Fig. 5, not shown) the cathodes are formed from metallized (Ag) strips on a glass plate, with offset areas coated with carbon. An anodized Al apertured plate is held in contact with the cathode plate, exposing the carbon areas to metallized anode strips on a window spaced above the Al plate. In a third embodiment (Fig. 6, not shown) the carbon coating completely covers the metallized cathode strips. In all embodiments it is essential that no base cathodic metal is exposed to the discharge, the characteristic being immediately impaired. The method of application of carbon disclosed in Specification 1,473,850 is referred to.

Gas is supplied to the system 16 from a pump 28, and is maintained at a pressure which is a function of the distance between the diaphragm 18 and the end of a bleed nozzle 20 adjacent thereto. The range of steady state pressures of the system 16 may be extended by a pneumatic relay 30, and a surge tank 17 may be connected to the system 16.
