Title: Apparatus and method for repairing elongated flexible strips having damaged sprocket feed holes along the edge thereof
IPC: G03D15/04
Filed: 1975-10-22
Abstract: 1495038 Repairing damaged film perforations J S STANFIELD and P W TRESTER 22 Oct 1975 [29 Nov 1974] 43269/75 Heading G2E Film-strip having damaged or missing sprocket holes along one edge is repaired by attaching a reinforcing strip having corresponding sprocket holes. The film 22, whose sprocket feed perforations 24 may have been damaged or even torn away altogether, as seen in Fig. 2, passes from a supply spool 26 into the repair section of the apparatus, which is mounted on a support frame 44. The repair strip 34 is provided in the form of a roll of tape 32, already prepared with perforations which correspond with the perforations in the film-strip, and having a pressure sensitive adhesive on one side. The film is wound off spool 26, and passes between a pair of rollers 50, 52, the lower of which is heated, so as to smooth and straighten out the film. It then passes over guide rollers 70, 71 to the actual repair station which comprises two rollers 56, 58, between which the film and tape are passed in contact. The lower roller 58 has a smooth metal surface with sprocket teeth 60 round its periphery (seen more clearly in Fig. 4 (not shown)). The upper roller 56 carries a resilient rubber sleeve 74, having a series of apertures (114) (Fig. 4) which correspond with the sprocket teeth 60 (see also Fig. 7 (not shown)). As the film and repair tape are brought into contact between rollers 56, 58, they are initially aligned by a sprocket tooth passing through a sprocket hole in each. They are then laminated together as they are wound on by means of a handle, and are passed between a further pair of rollers 64, 66, which apply further heat and pressure. The film is finally wound on to a take-up reel 38. Thus the sprocket holes in the tape form reinforcement or replacement holes for those in the film.

Abstract: 1529193 Dialkanolamines SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 22 Oct 1975 [24 Oct 1974] 43353/75 Heading C2C A continuous process for preparing dialkanolamines comprises continuously contacting an olefin oxide with ammonia in a first reaction zone, continuously recovering monoalkanolamine from the effluent from said first zone, and continuously reacting the recovered monoalkanolamine with an olefin oxide in a second reaction zone, the reaction conditions in said zones being such that the amount of monoalkanolamine produced in said first reaction zone is substantially equal to the amount of monoalkanolamine converted in said second reaction zone. (a) Preferably the process comprises contacting a C 2-4  olefin oxide and excess aqueous ammonia in the first reaction zone; (b) removing the ammonia and water from the resulting first reactor effluent in an ammonia-water removal zone, thereby producing an aqueous ammonia overhead which is recycled to the first reaction zone and an ammonia-free bottoms stream; (c) separating the ammonia-free stream from the ammonia-water removal zone in a monoalkanolamine separation zone to produce a monoalkanoalamine-rich overhead stream and a dialkanolamine-rich bottoms stream; and (d) contacting the monoalkanolamine-rich overhead stream from the monoalkanolamine separation zone with a C 1-4  olefin oxide in a second reaction zone to convert said monoalkanolamine to dialkanolamine. Preferably the reactor effluent from said second reaction zone is combined with the ammonia-free bottoms stream from the ammonia-water removal zone and the combined stream is routed to the monoalkanolamine removal zone.

Abstract: 1,022,901. Semi-conductor devices. PHILCO CORPORATION. Nov. 16, 1962 [Nov. 16, 1961], No. 43403/62. Heading H1K. A germanium semi-conductor device having a connecting member adjacent a rectifying region near the surface of the germanium is provided on the surface adjacent the connecting member with a layer of germanium oxide. In the embodiment (Fig. 2) a germanium wafer 10 is provided with a surface skin 38 by diffusion of donor impurities into the surface. Emitter and collector pits 12 and 13 are formed by jet electrolytic etching and emitter and collector dots 14 and 16 of cadmium are formed by jet-electroplating, followed by low temperature alloying. Silver emitter and collector leads and a nickel ohmic base contact 18 complete the assembly. The collector connection and surrounding semiconductor surface is subjected to an electrolytic jet-etching treatment (Fig. 4, not shown), using a KOH solution with the wafer subjected to intense illumination throughout. After washing in deionized water the collector region is then bathed in meta-germanic acid either in a bath or in the form of a stream or drops from a nozzle and subsequently heat dried in a furnace under reduced pressure. The method may also be applied to germanium surface barrier transistors with indium emitter and collector electrodes but in this case the preliminary cleaning is by chemical etching.

Abstract: 1468458 Safety closures for containers M B STULL 15 Oct 1974 [15 Oct 1973] 44686/74 Heading B8T A safety cap construction for a container comprises a cap body 14 with a top discharge opening 24 and cap 18 connected by flexible hinge 20, co-operable yieldable detent means to hold the cap on the cap body, e.g. bead 32 on spout 22 and bead 34 on skirt 36, an upstanding flange 26 preventing access to the juncture of the cap body and cap in the closed sealing position and pivot bearing means, e.g. surfaces 39, 40 on the cap body and rib 42 on the underside of the cap, whereby a lifting edge 56 of the cap 18 can be engaged by the finger of the user to pry the cap off the cap body when a depressing force is applied to a portion of the cap 18 adjacent to the hinge 20. A sealing plug 54, strengthening ribs 48, 46, upstanding lugs 59 and guard posts 61, 62 or (156), (158), Figs. 20-22 (not shown), may also be provided. Raised projections such as 58 or (160), Figs. 20-22 (not shown), can serve as an indication of the areas to be depressed. The bearing ribs may be offset from the longitudinal axis of the sealing plug, Figs. 6 and 7 (not shown), and reinforcing lands (94), (96), Fig. 8 (not shown), placed on the bearing surface of the cap body. In the embodiment of Figs. 9-11 (not shown) a portion (108) of the upstanding flange (102) lying between guard posts (104), (106), is made thinner and discontinuous from the rest of the upstanding flange such that easier access is allowed to the lifting edge as the cap is tilted. The lifting edge 56 may rest on the top of the portion (120) of the upstanding flange (116), Figs. 12 and 13 (not shown). The diameter of the sealing bead (130) of the cap, Figs. 14-16 (not shown) in the vicinity opposite the point of attachment of the hinge 20 can be reduced or increased, as can that of the cap body sealing bead 22 at a similar point. On the periphery of the sealing side of the cap (132), Figs. 17-19 (not shown), an annular guide bead (134) helps align the cap on resealing. In a further embodiment, Figs. 23-27 (not shown), the tilting of the cap is carried out at 90 degrees to the hinge section. When the closure is sealed, the lifting edge (179) rests on a ledge (202) formed on the inner surface of upstanding flange (26a) at 180 degrees to a detent nib (206). The bearing means consist of ribs (183), (185) on the cap and groove (187) and nib (189) on the cap body. Pressure applied to projection (177) forces the rim portion of the cap downwardly past the detent nib (206) allowing the lifting edge (179) to be readily gripped. The safety closure may be formed as a one-piece moulding of plastics material.
