Title: Treatment of molten ferrous metal
Inventor: KERR ROBERT
IPC: C21C5/32
Filed: 1962-08-14
Abstract: In a process for treating molten iron or steel by blowing with a stream of gas containing solid reagents a nozzle having two concentric passages is used, a high pressure stream of gas being supplied through the inner passage while the solid matter is suspended in a low pressure stream of gas supplied through the outer passage.  The same or different gases may be used for the two streams.  As solid materials, fluorspar, lime, bauxite, iron ore, graphite, coal and coke are referred to, while the carrier gas may be oxygen, nitrogen, carbon dioxide, propane or coke oven gas.  By feeding in a mixture of lime and graphite, it is possible to reduce the phosphorus and sulphur content of the iron without decarburization.  The nozzle may be used to melt a solid charge by passing high-pressure oxygen through the inner passage and low pressure fuel gas through the outer.

Title: Radar systems
IPC: G01S13/526
Filed: 1961-08-31
Abstract: 1380040 Pulse radar TELEFUNKEN PATENTVERWERTUNGS GmbH 31 Aug 1961 [3 Sept 1960] 31316/61 Heading H4D In an M.T.I. radar system, the received echo pulse sequence is arranged in groups of four, at the receiver, to eliminate the fixed target signals. I.F. frequency delay lines, at the receiver, cause each fixed target echo to adopt a quadrature phase displacement relative to the previous pulse such that the resultant of the summation of the amplitude of each group of four is zero. The moving target received signals are not eliminated by this process as they possess phase displacements which are different for each one of the group of four signals and which are a function of the target velocity. The addition of a further 90 degrees phasing between the four moving target signals of the group does not case the resultant of these vectors to be zero. In the embodiments described, those parallel delay circuits are provided which insert respectively, phase rotations of 90, 180 and 270 degrees. The resultant of the M.T.I. echoes is a function of the inserted angle for a given target speed and the largest is fed to the display unit by a selection circuit. A further small phase angle may be added to allow for antenna rotation. In one embodiment, the echo signals are not added vectorially but are represented by their X and Y co-ordinates. Fluctuation signals such as receiver noise and variation of echo signal strength are also reduced by the phase rotations.

Title: Improvements in or relating to servicing machines for nuclear reactors

Abstract: 927,359. Servicing reactors. BRISTOL AEROJET Ltd. Dec. 14, 1960 [Sept. 16, 1959], No. 31545/59. Class 39 (4). A reactor servicing machine comprises a shielded pressure vessel 1 mounted on a base 2 having wheels 3 whereby it may be driven on rails 4 and aligned with a selected standpipe 6 in the charge face 5. A pipe 12 extends from the bottom of the vessel 1 and carries a pipe 16, spherical surfaces 18, 19 on a flange at the upper end of the pipe 16 being received by similarly shaped surfaces of a socket secured to the pipe 12 to provide a universal mounting 17. A sealing ring 20 ensures fluid pressure tightness. A sleeve 21 slidable on the pipe 16 has its upper end formed as a piston 24 with seals 32, 33, the piston moving in the annular space between the pipe 16 and a cylinder 25 attached to the pipe by a flange joint 26. The lower end of the space is closed by an end cap 27 fixed to the cylinder 25 whereby by admitting fluid to the space above or below the piston 24 through a pipe connection 30 or 31 the sleeve 21 may be extended or retracted. When it is extended, as shown, its spherically shaped lower end surface 22 makes a pressure tight connection with a conical surface 23 on the standpipe 6. When the sleeve 21 is retracted a flange 39 thereon engages a flange 38 on a shielding ring 36 to lift the ring and provide a clearance 35 between the shielding and the charge face 5 to enable the machine to be moved. The machine may serve for charging a reactor with fuel elements but, as shown, it serves for the removal of control rods and standpipe plug and the insertion of a shoot, the fuel elements being subsequently transferred by another machine. A magazine 9 within the pressure vessel 1 has a number of chambers 11 which may be brought in turn into alignment with the pipe 12 by an indexing mechanism 10, the chambers serving to accommodate the equipment to be transferred, the transfer being effected by a grab 14 controlled by a winch 15.

[Class 7 (iii).] In a vaporizer comprising three nested coaxial casings 7, 17, 25, forming a vaporizing chamber, a cooling chamber 26 and a final collecting chamber 27 and in which streams of combustible mixture pass upwards through spiral passages 15 in the vaporizing chamber which is heated by exhaust gases passing through a surrounding casing 5, the lighter portions of the mixture flowing adjacent the comparatively cool wall of the casing 17 forming the inner sides of the passages while the wet, heavier particles of fuel are thrown against the heated outer walls, the entire mixture, after passing the mixture inlet 8 and before reaching the spiral passages 15 is split up into a greater number of streams by curved partitions B, greater in number than the partitions 14 defining the passages 15 and set at an angle thereto. As shown, the partitions B are formed on the wall of the chamber 7 and the passages are closed at the top by the inclined bottom walls of the inner casing 17 which is removable and has the helical partitions or ribs 14 formed integrally with it. The mixture from the passages 15 flows down the wall of the casing 17 through the cooling chamber 26 formed between that wall and the inner cylinder 26, and then up through the cylinder to outlet ports 30.

Title: Improvements relating to electrical time measuring arrangements
IPC: H04M3/12
Filed: 1934-11-06
Abstract: 446,433. Valve relay circuits. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, and HUMPHRIES, H. E., 61, Rochester Way, Blackheath, London. Nov. 6, 1934, No. 31868. [Class 40 (v)] A predetermined time period is measured from the receipt of a start signal by causing charges to be delivered periodically to a reservoir condenser controlling the striking of a gas-discharge tube. The Figure shows a start relay A which energizes a slow-release relay B which controls a further slow-release relay C and a relay E. Relay C opens the circuit of B so that these relays interact. Contacts of relay B charge condensers QA, QB, QC in parallel and discharge these condensers in series into reservoir condenser QD. When this condenser is charged gas-discharge tube NT breaks down to operate relay D between the time when contact b4 and the time when contact el is operated so that break down of the tube without operation of the relay D is prevented. The current source is so arranged that it assists both in charging the reservoir condenser and in producing the break-down of the discharge tube. When terminals TE1, TE2 are strapped a succession of periods is measured off with continued application of the start signal due to release of relay A over winding II and contacts a1, d2. The charging voltage across the points X, Y is stabilized by the lamps ML, CL, while the effect of change in battery voltage is minimized by the change in the operating lag of relay C and bv the use resistance-elements which may have a non-linear current-resistance characteristic. In a modification, Fig. 2 (not shown), provision is made for a number of time measuring units with common interacting relays which are timed by a choke condenser combination shunted by an adjustable control resistance. The latter may be replaced by a plurality of resistances corresponding to the plurality of units associated with the apparatus to give appropriate adjustment of the " make " and '' break " periods. In this modification break-down of the discharge tube without operation of the relay is prevented by the locking up of a shunt relay of the high-speed kind described in Specification 405,436, [Group XXXVII].
