Title: Improvements in rifle grenades and the like
IPC: F41G1/48
Filed: 1964-03-31
Abstract: 1,015,610. Rifle grenades; sighting plates. BREVETS AERO-MECANIQUES S.A. March 31, 1964 [April 9, 1963], No. 13178/64. Heading F3A. A rifle grenade has a sighting plate 3 pivotable between a retracted position lying against the tail sleeve 1 and a firing position in which it extends perpendicularly to the tail sleeve, the sighting plate 3 being pivotally connected to a U-shaped clip having folded extensions which fit resiliently over the trailing edges of the grenade fins. The sighting plate 3 is connected to the base 4a of the resilient U-shaped clip which has branches 4b provided with extensions 4c having hook projections 4d in their ends. The clip and plate are slipped over two adjacent fins 2 and held in place by the folds between the branches 4b and the extensions 4c bearing against the trailing edges of the fins, and the projections 4d engaging in holes 6 in the fins. A flat face 7 on the lower end of the sighting plate 3 enables the clip to be positioned as shown for firing or to lie along the tail sleeve 1 as shown by broken lines during handling. The fins 2 are fixed in position by a resilient holding ring 5 engaged in a groove in the tail sleeve 1.

Title: Production of low sulphur chromium(iii)oxide pigment
IPC: C09C1/34
Filed: 1975-04-01
Abstract: 1498300 Low S-containing Cr 2 O 3  pigment BAYER AG 1 April 1975 [3 April 1974] 13188/75 Heading CIA Low S-containing Cr 2 O 3  pigment (e.g. less than 0À005% by wt.) is prepared by reducing a finely divided alkali metal chromate in a heated hydrogen-containing reaction zone at a temperature of from 900 to 1600‹ C., the reaction zone being followed by a dwell zone in which a temperature of 900-1600‹ C. is established by additional direct heating by introducing an oxygen-containing gas into the dwell zone; the Cr 2 O 3  is recovered in the form of an aqueous suspension. Reduction is preferably carried out in the presence of salt forming gas (e.g. Cl 2 , HCI, Br 2 , HBr, NO, NO 2  or CO 2 ) to bind the alkali metal ions. Ideally, the temperature difference between dwell and reaction zones is no more than 200‹ C. Advantageously, finely divided SiO 2  is added to the chromate before introduction into the reaction zone; the SiO 2  may be formed by vapour phase hydrolysis of SiCl 4  yielding 0À1 to 2% by wt. of SiO 2 .

Title: Electrophotographic Copying and Apparatus therefor.

Filed: 1967-03-21
Abstract: 1,158,209. Electrostatic printing. RADIO CORPORATION OF AMERICA. 21 March, 1967 [28 March, 1966(2)], No. 13323/67. Heading B6C. [Also in Division G2] Multiple copies are formed from a latent electrostatic image on a member by developing the image with toner, contacting the member with a transfer sheet, transferring the toner image to the transfer sheet without destroying the electrostatic image by applying a potential, and repeating the sequence of development and transfer until the desired number of copies has been formed, the potential used at each transfer being greater than that used at the preceding transfer. In an apparatus (Fig. 6) for forming multiple copies of images appearing on a thinwindowed cathode-ray tube acting as a computer read-out, a web 52 having a photo-conductive surface 86 is unwound from a reel 54, charged by a double corona discharge device 88, imagewise exposed to form a latent electrostatic image by the cathode-ray tube 94, the window of which is protected by a transparent web 96, developed at station 70D with toner from development apparatus 70C, contacted at station 70T with a transfer web 70S by a pair of conductive rollers 70A and 70B across which a potential is applied whereby the toner image is transferred to the transfer web and fixed thereon by heat 70H passed through further pairs of development and transfer stations 72D-80D and 72T-80T whereby further copies are formed on webs 72S-80S, passed under a vacuum cleaner 134 optionally having brushes which remove any remaining toner, and wound on a reel 56 for further use. Each development apparatus comprises a container 106 having an open end adjacent web 52 and holding a mixture of electroscopic toner and magnetic carrier particles which is applied to web 52 by a cloth belt 110 and a bristle brush 116 using an electromagnet 124; excess developer is removed by an electromagnet 122 and rollers 118 and 120. In a similar apparatus (Fig. 8, not shown) all the developer (85) is applied by a bristle brush (81) which is loaded by developer from a hopper (95) using a conveyer belt (87). In an alternative arrangement the latent electrostatic image is applied directly to an insulating surface of the imagebearing member thus obviating the use of a photoconductive surface.

IPC: A61C13/00
Abstract: 134,030. Fisher, A. W. Oct. 23. 1918. Teeth, artificial. - An upper denture of the kind provided with a removable suction disk held in place by an aluminium or gold stud is moulded with the disk and the retaining-stud in position. A soft-rubber annular suction disk a, with its retaining-stud b, c in position, is enveloped in tin-foil d, e and placed concentrically over an annular recess k<1> formed in the mould k as described in Specification 121,143, by means of an annular pliable metal disk attached to the impression of the mouth from which the mould is cast. The denture is then packed and vulcanized so that the vulcanite fills the hollow shank b of the stud, which is anchored to the vulcanite by means of a bent-over edge, or roughenings, or teeth formed on the end of the shank b. The central aperture in the suction disk a may be larger than the shank b of the stud. In this case, the stud is secured to the tin-foil d by adhesive so as to remain concentric with the disk a, and its shank b becomes surrounded and enlarged by an annular neck of vulcanite. The top of the stud is depressed below the general level of the denture, owing to the thickness of the tinfoil, and the periphery of the suction disk pro. jects above the level of the denture, and! is moulded to the contour of the palate.

[Class 57] [See also Group XXXV] An internal-combustion engine controlled by a speed governor having a regulating device which limits the quantity of injected fuel per cylinder below certain predetermined speed values, drives an electric generator which is so regulated that a decrease of the speed of the engine is accompanied by a decrease of the power developed by the generator which is greater than the decrease of the power developed by the engine. The electrical transmission described in Specification 428,862, [Group XXXV], may be used. The line A-B represents governor control of the engine with decrease of speed accompanied by increase of power. At the lower limit of speed B, the governor ceases to function and the line B, E then represents engine power diminishing with speed. The power developed by the generator in relation to speed is represented by one of the lines 3, 4, 5, each of which is steeper than the line B, E and intersects it at an equilibrium point.
