Title: An electronic timing circuit
IPC: H03K3/351
Filed: 1966-10-21
Abstract: 1,129,423. Transistor timer circuits. MALLORY TIMERS Ltd. 21 Oct., 1966 [21 Oct., 1965], No. 47331/66. Heading H3T. In a circuit for energizing a load for a predetermined period, an initiating signal changes the state of a bi-stable multivibrator to render a switch non-conductive and so start a timing circuit which at the end of the period resets the multivibrator, the D.C. supply to the circuit being derived from a D.C. source coupled to an A.C. supply. Operating switch 18 causes transistor 30 of a bi-stable multivibrator circuit 29, 30 to become non-conductive so that transistor 35, which is connected to transistor 29, also becomes non-conductive. This allows a timing capacitor 43 to charge (from A.C. supply rectifier 17, 18, 19) until it "fires" a unijunction transistor 39 which, through a capacitor 36 resets the multivibrator and so renders transistor 35 again conducting. During the period transistor 35 is non-conducting an S.C.R. 46 is so biased that it conducts current from the A.C. supply applied to terminal 54 and energizes the load. This load may be connected directly or through a bridge rectifier to the S.C.R. Fig. 4 illustrates an alternative output circuit to replace the S.C.R., comprising a PNPN diode (60) which produces voltage spikes for firing an A.C. gate controlled rectifier (62). The bi-stable circuit 29, 30 comprises a capacitor 33 for setting it, on first switching, on to the state in which 30 conducts.

Filed: 1962-12-28
Abstract: 969,142. Absorbing radio waves. SIEMENS & HALSKE A.G. Dec. 28, 1962 [Dec. 28, 1961; Sept. 13, 1962], No. 48759/62. Heading H4A. A wall which will absorb electromagnetic radiation is built from a plurality of solid or foamed plastic blocks 1, 2 some of which (2) have two or more of their side faces coated with a layer of a material which has a high resistivity yet is electrically conducting, these blocks 2 being so disposed within the wall that the coated faces form a lattice network. As shown, the blocks 2 have all four side faces coated and constitute each alternate block. Alternatively, all the blocks may have two adjacent or two opposite side faces (Fig. 8, not shown) so coated. To increase the absorption effect two or more walls may be arranged one behind the other, the walls being built from blocks of different sizes. The same effect is obtained if the dielectric constant of the block material increases with distance from the incident radiation and if the magnetic permeability of the blocks is greater than that of air. If low acoustic reflectivity is also required, the blocks can incorporate sound-absorbing substances. Specification 969,141 is referred to.

Abstract: 1357308 Calibrating wheel-rims GIANETTI SpA 24 Oct 1972 [30 Oct 1971] 48997/72 Heading B3A A method of calibrating partly-finished wheel rims 1 comprises placing the partly-finished rim on to a calibrating machine and applying radially outwardly directed and radially inwardly directed forces to the rim successively. In operation a partly-finished rim 1 is placed on a disc 2 at the upper limit of stroke of a ram (3), Figs. 5-8, 10 (not shown). Ram (3) is then lowered to introduce the partly-finished wheel rim into the inner cavity of outer die D. Ram portions 6, 9 then descend until slidable sectors 8 of inner die E enter the rim, and annular member 10 has partially thrust slidable sectors 5 of the outer die D inwardly. Ram portion 9 remains stationary while ram portion 6 continues to descend. Sectors 8 expand radially outwardly, due to a frusto-conical member 7, and cause dilation of the rim. Straightening out of radial flange 1a is performed by compressing the flange between the flat surfaces of sectors 5, 8, Fig. 9 (not shown). The ram portion 6 is then partially raised so that sectors 8 carried by movable members 8a move radially inwardly under the action of biasing means (not shown) to become separated from the inner surface of the rim. Ram portion 9 is then lowered so that inclined planes 14, 15 engage to urge sectors 5 radially inwardly and complete the calibration operation, whence the rim can be unloaded either manually or automatically (as for the loading), by raising ram portions 6, 9 simultaneously with the disc 2.

Title: Gas turbine plant and method of operating the same
IPC: F02C7/12
Filed: 1964-12-04
Abstract: 1,093,247. Gas turbine plant. C.R.J. LAQUEUILLE. Dec.4, 1964, No. 49477/64. Headings F1G and F1T. In a gas turbine engine the blades of one or more blade wheels are cooled externally by the flow of air, the air being supplied laterally to the blade spaces adjacent the blade roots and flowing radially outwardly through the blade spaces, the blade spaces being laterally closed for this purpose by means of casing portions; the air discharging from the blade spaces is supplied to one or more combustion chambers the gases from which are directed on to the turbine blades. The gas turbine engine shown in Figs. 1 and 2 comprises an axial-flow compressor 2, combustion equipment 9, a first-stage turbine 6 and a second stage turbine 12, the compressor and turbines being mounted on a common shaft 1. Air from the compressor passes through a duct A and is directed by an arcuate sector of blades 4 into the spaces between rotor blades 5 of the firststage turbine 6, the air flowing radially outwardly through the blade spaces thereby cooling the blades. The blade spaces in this region are closed off by the walls of the turbine casing so that the blades act to further compress the air flowing through the blade spaces. The air then discharges through a diffusor 7 into the chamber 8 from which it passes into a series of combustion chambers 9. The gases issuing from the combustion chambers are directed by inlet guide blades 11 so as to act on the blades 5. The gases discharging from turbine 6 pass to the second stage turbine 12. The arrangement of air inlet guide blades 4, turbine rotor blades 5 and diffusor 7 is shown in more detail in Fig. 3. The guide blades 4 direct air towards the radially inner parts of the blade spaces while the inlet guide blades 11 direct gases towards the outer parts of the blades as indicated in broken lines in Fig. 3. In Fig. 5 at Section AA combustion gases are being directed on to the turbine blades 5 and the radially inner parts of the blades are covered by a wall portion 13. At Section BB cooling air is being directed into the blade spaces and the radially outer portions of the blades are covered by a wall portion 15, the radially inner portions of the blades being open for the flow of cooling air. The cooling air discharges radially outwardly from the blade spaces into the diffusor indicated at 8 being guided by vanes 7. At Section A'-A', the radially outer portions of the blades are again open for the flow of combustion gases and the radially inner portions are covered by the wall 13. In Fig. 6 air compressed in a centrifugal compressor 2 is passed into the turbine blade spaces for the cooling function, the air then being further compressed in a second centrifugal compressor 22. The air discharging from compressor 22 is pre-heated in an air heater 23 before passing to the combustion equipment 9. The exhaust gases from the turbine 6 pass through the air heater 23.
