Abstract: 833,523. Making turbine blades; extruding. ROLLS-ROYCE Ltd. Jan. 10, 1958 [Jan. 11, 1957], No. 1231/57. Classes 83 (2) and 83 (4). A method of making a turbine blade from heat-resistant metal comprises providing a billet 10, Fig. 2, with a plurality of drilled holes 11 and inserting a filler therein, partially extruding the billet through a die 12, 13 to form a blade portion of approximately aerofoil shape and to leave an unextruded shroud portion 15, Fig. 7, the holes being thereby deformed into elongated or lenticular cross-section, Fig. 7A (not shown), machining the blade portion and root portion to final shape, machining a tip shroud 19, Fig. 7, from the unextruded portion 15, and removing the filler at any stage subsequent to the extrusion. The billet of nickelchrome alloy, is of substantially rectangular cross-section, Fig. 2A (not shown), and has axial or inclined blind holes filled with mild steel rods located by welding. The billet is then coated with nickel and after heating is extruded through a split die.12, 13, Fig. 3B, coated with colloidal graphite as described in Specification 828,339. The blade portion may be twisted during or after extrusion. For forming an oblique tip shroud, the base of the billet and the corresponding surface of the extrusion die are inclined. Side pieces 23, Fig. 8, are then welded to the extruded portion to provide material for the platform 22 which is machined together with a root shank 21 and fir-tree fixing 20. Holes 24 are drilled in the root to connect with the holes in the blade portion. The filler rods are removed by nitric acid to which is added a wetting agent as described in Specification 833,522. Specification 826,498 also is referred to.

Abstract: 1,029,901. Mechanical garages. MOTOPARKS Ltd. Jan. 10. 1964 [Jan. 21, 1963], No. 1275/64. Heading B8E. A mechanical garage control system, whereby a vehicle transporter automatically performs a predetermined sequence of operations signalled to it in advance, employs coils adjacent the path of movement of the transporter which, when energized, cause receiving coils on the transporter to operate contactless relays controlling its operation. In Fig. 1, which shows one storey of a multistorey system, the transporter consists of a trolley A movable along a trackway 3 and a superimposed trolley 2 movable from the trolley A to and from parking compartments 4 and a lift 1, the construction of the trolleys and compartments preferably being as described in Specification 830.418. The trolleys have a waiting position adjacent the lip and each cycle of operations is initiated by the energization of a fixed coil such as 7 which in turn energizes an adjacent coil 8 on the transporter. The receiving coil triggers a transistor flip-flop circuit (Fig. 4, not shown) which constitutes the first relay of the transporter control, all the relays being of this type. Further coils and relays control the subsequent operations which, in the case of a parking operation, follow the path indicated in broken lines. The system is key operated, a key magazine 30, Fig. 9, ejecting a key 31 for issue to the driver at the entrance. The ejected keys, which are slotted bars (Fig. 9b, not shown), each pass a succession of photo-cells 32 whose outputs are signalled to the appropriate lift controls and coils on the assigned parking floor. These signals are permissive only, the actual movements being effected in response to further signals-in " AND " function relationship with the initial signals-made by the vehicle or vehicle transporter when in the appropriate position. The detailed circuitry is disclosed in Figs. 2 to 5, 6 and 11 (not shown).

Title: Improvements in or relating to transmitters for liquid level measuring devices
IPC: G01F23/296
Filed: 1946-01-15
Abstract: 609,508. Electric indicating systems. LIQUIDOMETER CORPORATION. Jan. 15, 1946, No. 1356. Convention date, Sept. 8, 1945. [Class 40 (i)] In a transmitter for a liquidlevel measuring device, a partly immersed member is caused to vibrate by an electrical oscillating means at a frequency a function of the liquid level. In the embodiment shown, the metal bar 3 is supported at 4 in the vessel 1 containing liquid to the level 2 and urged to a central position at its upper end by the springs 5. The rod 7 is attached to the bar at right-angles at 6 and supports the ferromagnetic plunger 9 and permanent magnet 8 inside the guiding enclosure 10 of non-magnetic, lowconductivity material. Coils 11 and 12 surround the plunger 9 and magnet 8 respectively, the former being connected in the circuit of anode 19 of valve 21 and the latter between the grid 16 and cathode 20. After switching-on, the plunger 9 is drawn into coil 11 and causes the member 3 to move to the right and the magnet 8 to be displaced within coil 12. The voltage thereby generated at grid 16 is such as to reduce the anode current and the member 3 is then moved to the left, by the springs 5, beyond the central position. During this motion the voltage at grid 16, due to the action of coil 12 and magnet 8 is such as to raise the current through coil 11 and the cycle is repeated at a frequency determined by the natural frequency of vibration of the member 3 which is a function of the liquid level 2. The frequency of the oscillator 13 is determined by device 14, the output of which operates indi. cating device 15, suitably calibrated. In a further embodiment, not shown, a magnetic vibrating member is maintained in motion by a magnet energized by the anode circuit of a valve, the grid of which is supplied with an A.C. voltage from a condenser, one plate of which is fixed and the other is formed of a section of the member.
