Abstract: 301,281. Dorey, W. A. Jan. 24, 1928, [Convention date.]. Lighting, systems of; ceiling lamps, - A lighting apparatus for producing illumination of high intensity over a predetermined area and a moderate illumination over surrounding areas comprises a group of lenses 15 and light sources 7 disposed above and offset from the axes of the lenses, so that the beams emitted from the lenses overlap. As shown applied to the illumination of an operating table 9, the light sources are enclosed in a chamber 10 recessed above the ceiling line 11. The interior of the chamber 10 has a matt white surface and the light sources have translucent specular reflectors 8 with their axes inclined towards the operating table. A frame 13 supports the lens sections 15 by mullions 14 arranged in squares, each lens section being a quarter of a complete condensing lens of the Fresnel type, and the light sources are. offset from the lens centres in varying degrees so that the beams from the lenses are directed towards a small space 31 above the centre of the operating table. The: interaction between the various light sources and the diffuse reflecting interior of the chamber 10 give general illumination. Curve 22, Fig. 1, shoe's the total horizontal illumination at the table level and curves 17, 18, 20 show the distribution of intensity from the various lenses. The end lenses 19 are tilted to obtain greater intensity along the, beam axis. To ensure that the lens sections 15 are positioned properly in the frame 13 the exterior corners 25, Fig. 5. of the lenses are bevelled and fit against inclined slugs 24 fastened in the mullion at its intersections, but the interior corners 26 - - 28 are not bevelled, nor are the corresponding mullion intersections fitted with slugs. The lamps may be connected together in groups and wired to separate switches permitting of selective control so that the direction and intensiy of the beams may be adjusted. The end lenses may be tilted upward from the main line of the frame 13 or the whole frame may be divided into two flat tilted sections. Figs. 11 and 15 show a modification adapted for lighting a vertical surface such as a blackboard 42 in which a number of light sources 33 are mounted in a recess 34 covered by a hinged lens-holding frame 35 flush with the ceiling. The light sources are offset from the axes 39 of the lens combinations which comprise an inner plate 47 having concentric prisms 48 and an outer plate 49 having parallel prisms 50. Each lamp 33 is provided with a spherical reflector 43 reflecting light back to the particular lens cooperating with that lamp. A part 45 of the recess 34 forms a wiring channel and the interior of the recess has a white matt surface except the wall 53, which may be finished black to reduce illumination of the wall 41 above the blackboard.

Abstract: 350,682. Dough-proving apparatus; bakery plant. WILSON, J. E., McCONNELL, S., of Ormeau Bakery, Ltd., Ormeau Road, and BROWN, C., 16, Haypark Avenue, both in Belfast. May 10, 1930, No. 14439. [Class 28 (i).] The dough pieces, which are either in tins or trays or without such carriers, are proved on a roller conveyer, and delivered thereby to the baking apparatus, e.g. to the plates of a travelling oven or to travelling hot plates. The rollers are positively driven continuously or non-continuously, e.g. by gearing, the wheels at each side being arranged alternately fast and loose, or by a worm or chain drive. Alternatively, some of the rollers may be driven continuously and some non-continuously. As shown, the rollers 4 are journalled in a frame 1 which is pivoted at 3 to allow the conveyer to accommodate itself to the unevenness of the oven plates 5a. The front of the conveyer is supported from the plates 5a by rollers 6, and the frame 1 has an overhanging portion 1a to permit the foremost rollers 4 to be close to the plates 5a. The drive is effected at both sides of the machine by worms 7a on shafts 7 which engage with worm wheels 7b on alternate roller shafts. In the overhanging portion 1a of the frame 1, the rollers are driven by meshing gear wheels, alternate wheels being idlers. Endless side bands 9, with adjustable tensioning-means, support the sides of the outer dough pieces and assist their movement. The bands are driven by pulleys 10. Some or all of the rollers 4 may be formed with barrel-shaped portions 4a, Fig. 4, preferably fluted as at 4b, to assist the travel of the dough pieces. Flour, contained in a trough 12, is applied to the rollers 4 and prevents the dough pieces from sticking. Central or other supports may be provided for the rollers 4. The dough pieces may be placed upon the roller conveyer by a trough which discharges a row of pieces simultaneously, or, alternatively, the pieces may be fed on a board and an arm or like member arranged to push them simultaneously on to the rollers. In another method of feeding, a guide board, against which an operator places the pieces, moves with the conveyer until a row is completed, and then makes a quick return for the next row.

Abstract: 1350474 Articles of bulk polymerized acrylic copolymers HYDROPHILICS INTERNATIONAL Inc 13 May 1971 [13 May 1970 3 May 1971] 14847/71 Heading C3P [Also in Division G2] Hydrophilic polymer articles comprise a polymer made by bulk polymerization at an initial temperature of 40-65 C. and a final temperature of 80-95 C. of a monomer mixture comprising 50-95% of one or more C 1 -C 4  alkyl acrylates and/or methacrylates, 5-30% of acrylic and/or methacrylic acid, and 0-20% of one or more C 8 -C 18  aliphatic esters of acrylic and/or methacrylic acid, the percentages being by volume, based on the total monomer volume, the carboxylic acid groups on at least one surface of the article having been neutralized (without saponification of ester groups). The polymers are prepared in the form of, e.g. sheets or rods by carrying out the bulk polymerization in situ in a mould or casting cell, using a free radical generator, e.g. azodiisobutyronitrile, or U.V. light as initiator. Small amounts of a chain stopper, e.g. dodecyl mercaptan, and a cross-linker, e.g. ethylene glycol dimethacrylate, allyl methacrylate or divinyl benzene, may also be present. Neutralization is effected by treating the article with an aqueous base, such as NaOH, NH 4 OH, KOH, Ca(OH) 2 , ethanolamine or sodium tripolyphosphate. Neutralization may also be effected throughout the article, the depth of neutralization depending on the concentration of the base, and the duration of the treatment. The neutralized portions are hydrophilic and swell in water, in which state they can absorb therapeutic agents, such as pilocarpine, which are then slowly released by the polymer. In the examples sheets, rods or contact lenses, are formed from polymers or methylmethacrylate and acrylic acid, with or without ethylene glycol-dimethacrylate, divinyl benzene or ethyl hexyl acrylate, and are treated with NH 4 OH or NaOH. In Example 11, a contact lens of the invention is treated with pilocarpine solution; when in use, the substance is slowly released into the eye.
