IPC: B21K1/22
Filed: 1919-12-03
Abstract: 159,338. Austin, Sir H. Dec. 3, 1919. Railway vehicle details.-For the production of railway buffers and other parts consisting of a shank and a head, a blank is inserted in a matrix and operated on by press tools. The matrix A, Fig. 1, is provided with a sliding liner B, through the centre of which a punch C is adapted to operate on the blank D. The matrix has a removable base A<1>. In operation, the liner and punch being retracted, the blank is inserted and the liner returned to the position shown. The punch C is then forced down, causing the lower unsupported part of D to flow radially. The final pressing is effected by the simultaneous downward movement of the liner and punch till the face a engages the shoulder b. For removing the finished article, the punch and liner are raised and the base A<1> of the matrix removed laterally, after which a second operation of the punch ejects the finished piece. In making hollow shanks, the punch may be reduced in diameter for a part of its length. In a modification, a press E, Fig. 6, works from the end opposite the punch, and in this type the press E may have a central bore for producing a flange between the shank ends.

Filed: 1936-11-09
Abstract: 484,219. Clocks. FERRANTI, Ltd., and BARNES, H. W. Nov. 9, 1936, No. 30432. [Class 139] A clock or like isochronous device comprises a synchronous electric motor 1 and a spring- driven motor 2 which operates continuously and drives the clock or like device when the electric motor fails. The synchronous motor 1 winds up the spring motor 2 through gears 23, 22, 21, and drives the ratchet wheel 10 through gears 4 to 9 and pawl 3. The spring motor drives the pawl 20 similarly through gears 17, 18, 19 at a slightly slower speed than pawl 3 so that ratchet 16, which with 10, is fixed to the shaft 11, is over-ridden by pawl 20, unless the synchronous motor fails. The drive to the clock is taken through gears 12, 13, 14, 15. The spring motor is controlled by an escapement (not shown) through gears 24, and drives an ancillary load through gears 26. This load may take the form of an air fan brake 25, as shown or be derived from the friction of a gear train. The object of this load is to make the load on the spring motor when running freely, comparable with the load when it is also driving the clock.

Abstract: 1,003,395. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 4, 1964 [Aug. 1, 1963], No. 30725/64. Heading G6C. A nuclear reactor and a heat exchanger separated from each other by radiation shielding are disposed in a vessel which is mounted within a second vessel; a first annular zone is defined by the adjacent walls of the two vessels, and the wall of the inner vessel is a double wall having between the two walls a further annular zone; a secondary coolant is circulated through the first annular zone at a temperature below the temperature of the primary coolant leaving the heat exchanger. The reactor 2 is supported on a radiation shield 28 mounted at its periphery on the inner wall 22 of the double-walled inner vessel. The heat exchanger 4 is mounted indirectly on a bed-plate 20, which also supports the double-walled container. The second or outer vessel 6 is of concrete, and acts as a restraining vessel for the primary coolant pressure. The object of the invention is to protect this vessel from the hot primary coolant, and this is achieved by passing cool CO 2  gas through the regions A, B and C at a slightly higher pressure than the primary coolant pressure. Three embodiments are described. In the first, as shown, secondary coolant passes from pump 72 through lines 74, 76 to zones B and 10. Gas from B flows up through annular zone F and out through pipe 78. Gas from fuel handling zone 10 filters down to zone C through leakage ducts in the fuel channel cap 38, and radially out through zone C to the exit. A portion of reactor primary coolant (also CO 2 ) is bled off through line 84, cleaned, and fed into the secondary coolant circuit; there will be slight compensatory leakage of secondary coolant into the primary circuit. In the second embodiment, a single series secondary circuit is used: 72, 74, B, A, 10, standpipes, C, 78, 80, 72. In the third embodiment, no reversal of flow takes place in the shield 12; the flow is: 72, 74, B, A, C, standpipes, 10, and, via an outlet pipe in 10, to the pump 72. In the fourth embodiment, all the secondary gas passes through the standpipes into the primary coolant, instead of directly to the pump 72. The pipework and circulation are as in Fig. 1, except that circuits 76, 78 are removed.
