Title: Improvements in and relating to dummy rifle apparatus for practising marksmanship
IPC: G07F17/38
Filed: 1930-06-11
Abstract: 363,373. Coin-freed shooting apparatus. BOWLER, E. A., 42, Park Street, South Geelong, Victoria, Australia. June 11, 1930, No. 17919. [Class 27.] Relates to coin-freed mechanism for dummy rifle apparatus of the kind in which the aim is recorded by the ignition of one of a number of lamps arranged on the target. As shown, the trigger 8 of the rifle is armed by a lever 32, Figs. 1 and 2, an extension 34 of which is connected to a coiled spring 33 and to a rod 31. On arming the trigger the rod 31 is retracted and a coin, which has previously been inserted in a slot 37, falls into the position 32a. On firing, the rod 31 is moved under the action of the spring 33 and the coin impinges against and moves a pivoted lever 29. To this lever is connected a rod 38 the lower end of which is pivotally connected to a lever 39, Fig. 3, which, when the rod 38 is raised by the movement of the lever 29, is adapted to pivot about a pin 40 secured to a plate 41. One end of the lever 39 carries a weight 42 and is adapted to engage with a spring-actuated contact point 46 which is arranged in same circuit as the lamps on the target. The other end of the lever carries a connecting-rod 43 a plunger 44 on which moves in a cylinder 45 filled or partly filled with oil. By this means the lamp circuit is closed for a sufficient time, when the trigger is pulled, to enable the marksman to ascertain the result of his " shot."

Title: Coordinate-measuring machine
IPC: G01B11/00
Filed: 1972-04-18
Abstract: 1358638 Measuring in three co-ordinates V I AXENOV A I ASEEV and V P KORONKEVICH 18 April 1972 17962/72 Heading G1M A machine measuring in co-ordinates X, Y and Z comprises a bed 1, Fig.1, supporting a slidable table 2, an object 3 to be co-ordinated and measured, and measuring optical units for each co-ordinate, each of which units is movably linked with a correcting member such as 11 so that the machine error at a given measurement point may be corrected for by suitable deviations applied by 11. Each of these co-ordinate measuring units comprises a digital laser displacement gauge having a movable part which is a reflector 6 fixed to the table 2 and a fixed part comprising a interferometer 4. A fine reading indicator 7 is placed between 4 and 6 and comprises an afocal system consisting of a transparent plate 8 and a similar,plate 9 vertically movable according to the position of the table 2 relative to the correcting member 11. In Fig. 2 the afocal system is a glass plate 13 pivotable about an axis 16 by an arm 14. In operation the object 3 is set up to orientate with the X, Y and Z axes and secured in position. The object and table are then moved a required distance (say between holes on the X axis for example) and simultaneously with this movement a change occurs in the distance between the fixed interferometer 4 and the movable reflector 6. As the table moves, the laser beam passes to the reflector 6 and back to 4 through the indicator 7 which adds a correction for machine error. The number of interference fringes on 4 is related to the dimension of the object or the table movement, so that by moving 9 or 16, the distance covered by the laser beam is changed and also the number of interference fringes which are proportional to the distance being measured. This change or displacement due to 9 or 16 is made proportionate to the machine error at each point along the length of travel of the table 2 so applying correction to the indicated measurement. Measurements along Y and Z are similarly carried out by a measuring head (not shown) and a movable spindle (not shown) and correction for these co-ordinates proceeds similarly.

Patent GB-735104-A (GB)
Title: Improvements in or relating to the manufacture of highly fluorinated carbon compounds
Inventor: STACEY MAURICE
IPC: C07C17/25
Filed: 1951-07-31
Abstract: Carbon compounds containing a high proportion of fluorine and a relatively low proportion of chlorine in the molecule are made by treating a chlorohydrocarbon containing at least 2 carbon atoms with a reactive metallic fluoride in which the metal exerts its highest valency state at 200-400 DEG  C., whereby hydrogen in the chlorohydrocarbon is replaced by fluorine.  Chlorohydrocarbons used contain a relatively low proportion of chlorine to hydrogen atoms in their molecules.  Specified metallic fluorides are cobalt and manganese trifluoride and silver difluoride.  The chlorofluorocarbons may be treated with a reducing agent, particularly a reactive metallic hydride, preferably lithium aluminium hydride, and the chlorine atoms replaced by hydrogen to yield fluorocarbons which on treatment with concentrated aqueous alkali yield unsaturated fluorocarbons.  The products may be used as lubricants, hydraulic fluids and dielectrics and in the production of polymers.  In examples: (1) o-dichlorobenzene treated with cobalt trifluoride yields chloroundeca-, dichlorodeca- and trichloronona-fluorocyclohexane, and monochlorobenzene yields a similar range of products with a greater proportion of monochloroundecafluorocyclohexane; n-octyl chloride similarly treated yields chloropentadecafluorooctane; (2) the monochloroundeca- and dichlorodecafluorocyclohexane of (1) with lithium hydride respectively yield undeca- and dihydrodecafluorocyclohexane which are converted in (3) with aqueous potassium hydroxide to perfluorocyclohexene and perfluorocyclohexadiene respectively. Specifications 626,449 and 630,606 are referred to.
