Title: Improved process for the manufacture of cast products by metal pouring and device for the carrying into effect thereof
Inventor: BAUDET YVES
IPC: B22D7/00
Filed: 1964-01-30
Abstract: 985,169. Pouring metals. SOC. INDUSTRIELLE DE COMBUSTIBLE NUCLEAIRE. Jan. 30, 1964 [Jan. 30, 1963], No. 4024/64. Heading B3F. Apparatus for the manufacture of cast bars comprises a melting crucible 11 with a distributer 12 underneath. Orifices in the bottom of the crucible and distributer are closed by plugs 14 and 17 respectively and vertical casting moulds 13a and 13b are connected to the distributer by orifices 12a and 12b. Beneath the plugged orifice of the distributer is positioned an auxiliary mould or container 16. In operation, metal melted in the crucible 11 is allowed to pass into the distributer by fracturing the plug 14 by means of a punch 15. The metal then passes from the distributer into the moulds through the orifices 12a and 12b. When a predetermined time has elapsed, sufficient to ensure complete filling of the moulds the punch is again actuated to pierce the plug 17 to allow excess metal remaining in the distributer to flow into the auxiliary mould 16. The moulds are removed from the distributer when the metal has solidified.

Another high-pressure conduit is connected to a passage 15 in flange 3, which is connected to the axial passage 8, thus forming an elbow connection. Similarly a T- connection can be made with the pressure chamber having two radial passages, Fig. 2 (not shown), connected to high pressure conduits. The high pressure conduits abut the cylinder 1 and their passages are connected to passage 9 by long sleeves extending through the wall of cylinder 1.

Title: Improvements in and relating to printing telegraph apparatus
Inventor: SALMON REGINALD DENNIS
IPC: H04L17/18
Filed: 1950-02-17
Abstract: 681,209. Printing-telegraph receivers. CREED & CO., Ltd. Feb. 16, 1951 [Feb. 17, 1950], No. 4142/50. Class 40 (iii). A selector mechanism for a printing-telegraph receiver comprises a group of selector members individually linked to intermediate members operated in timed relation with the incoming signals by a group of cams and an interposing member controlled by the curvature of the receiving magnet for changing the point of fulcrum of the selector members from a point adjacent one end to an approximately central point to provide selective operation of the selector members in accordance with the received signals. The pivoted armature 2 which is assisted by cams 9 on a sleeve 6, has a projection 10 engaging with the interposing member 11 connected by a spring 13 to an extension of the armature. The member 11 is locked in its actuated position after response to a signal element by an appropriately shaped cam on the sleeve 6. The selector bars 21, guided in comb bars 22, 23 are supported between stops 32, 33 and are linked to the intermediate members 25 having arms 28 operated in timed succession by cams 31, 37, 38, 39, 40 and the sleeve 6. The arms 28 are preferably resilient in order to absorb the shocks of the impacts with the cams 31, 37 ... In response to a mark signal, the corresponding selector lever 21 is pivoted about the stop 33 and a projection 34 on a corresponding storage member 35 in the mark position M, all the members 35 being returned to the mark position before a new signal combination is received. When a space signal is received, the member 11 is moved to the dotted line position and the rocking of the member 25 causes the selector bar 21 to pivot about a point opposite the end of the member 11 and to rotate the storage member 35 to the dotted (space) position. The storage members 35 are carried on a pivoted frame 41 rocked by a cam 46 on a sleeve 47 and selectively engaging bell cranks 49 or 51 to move code bars 53 linked to notched discs 54 controlling the selection of a character or to pivoted vanes 55 determining a function to be performed. After the positioning of the bars 53, the storage members 35 which have been moved to the space position are returned to the mark position by a lever 57 actuated by a cam (not shown) on the sleeve 47.

Title: Process for the working-up of polyolefines
IPC: C08F6/02
Filed: 1962-02-02
Abstract: Olefine homo- or copolymers obtained by the low pressure polymerization of an olefine or olefines in a dispersing medium with the use of such Ziegler type catalysts and such conditions that polymers of high bulk density i.e. above 430 g/l. are obtained, are purified by treating the polymer in suspension resulting from the polymerization, with an alcohol to decompose the catalyst, then washing with water and finally an alkylene oxide is added. The polymer may then be further worked up. A Ziegler type catalyst is used to obtain the homo- or copolymers. This may be obtained by reacting titanium tetrachloride with aluminium-diethyl monochloride or aluminium-ethyl sesquichloride in such a manner that (a) the molar ratio of the titanium compound, introduced as TiCl4, to the aluminium-diethyl monochloride remains constant in the reaction vessel throughout the reaction or the titanium compound is present in excess, (b) the molar ratio of the titanium compound to the aluminium-diethyl monochloride is smaller than 1.5 in the final phase of the reaction, (c) the reactants are reacted while dissolved in an inert solvent at a concentration of 14 to 60% by weight, (d) the reaction is carried out at 0-20 DEG C., preferably 5 to 15 DEG C. and (e) the reaction is carried out while stirring well. The polymerization is carried out until the ratio by weight of dispersing medium to solid polymer is less than 1.6. In the purification the alcohol used preferably contains at least 3 carbon atoms e.g. isopropanol or butanol.  The alkylene oxides mentioned are ethylene oxide, propylene oxide, butylene oxide-1, 2, and phenoxy-propylene oxide. Preferably 0.05 to 0.3 mol of alkylene oxide is used for each equivalent of groupings present in the catalyst that react with the alkylene oxide. Preferably alkylene oxides of low molecular weight are used which, as such or in the form of their reaction products with HCl, are water-soluble or readily volatile, and which can readily be removed by washing with water or drying. Polyolefines mentioned are polyethylene, polypropylene, polybutylene and poly(4-methylpentene-1).

Title: Materials testing
IPC: G01N3/10
Filed: 1967-01-27
Abstract: 1,124,195. Correspondence control systems. INSTRON CORP. Jan.27, 1967 [June 27, 1966], No.4218/67. Heading G1N. In a material testing machine a specimen 64 to be tested is held between grips 28, 30. The grip 30 is fixed to a piston rod 36 of a hydraulic ram controlled by an electrically actuated valve 56. A load cell 62 produces a negative signal in response to load applied to the specimen which signal is compared with a positive desired load signal, from a source 70, in a comparator 68 the amplified output from which operates valve 56 to selectively apply hydraulic pressure to one or other side of a piston 34. In operation, with the machine in a stable state i.e. zero output from the comparator a call for increased load (e.g. by manually adjusting a potentiometer in the source 70) produces a signal from the comparator and piston 34 is caused to move downwards. A linearly variable differential transformer senses the downward movement of the piston rod and transmits a positive signal to an amplidyne 78 to control the magnitude and polarity of a voltage to a motor 26 which through gears 20, 22, 24 and via screws 16, 18, moves a crosshead 14 supporting the ram cylinder 32 downwards until the piston is again centred in the cylinder, at which position the output from the differential transformer is zero. Similarly a call for decreased load causes upward movement of the piston which is followed by an upward movement of the cross arm to centre the piston again.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 12, 1935.] [Class 83 (iv)] An open-mouthed container, e.g. a bath is drawn from a metal sheet in successive stages by a single patrix 7, the sheet edge grippers, e.g. 11, 12 being changed for other grippers with successively wider openings to allow for drawing successively to the depths I, II &c. The sheet has the corners cut off. The dotted lines, e.g. 14 Fig. 7, show the position of the edge after having crept in the grippers 11, 12 after the draw to the depth 8 as in Fig. 3. The opening 13 is also wider than the previous opening of the previous grippers. To prevent wrinkling, the edge grippers may contain dies 28, Fig. 11, which make ridges 26, Fig. 10, or radial ridges 31, Fig. 12, which are subsequently drawn out. The lower grippers may be built up with rings 38, 39, 40, so that after each draw a ring only need be removed, to prepare the grippers for the next draw. As the lower gripper 12 becomes more worn at the edge than the top gripper 11, their positions may then be reversed.
