Abstract: 1,187,476. Air cushion vehicles. HOVERMARINE Ltd. 17 July, 1968 [17 July, 1967], No. 32815/67. Heading B7K. In a side-wall or other air cushion vehicle having a flexible skirt, the centre of pressure of the vehicle supporting cushion may be moved by displacing regions of the skirt by means responsive to pitching or other movements of the vehicle when travelling over an irregular surface. The skirt, shown at the bow of the vehicle, comprises a plurality of elements 13 having a U-shaped lateral cross-section made from sheet material ; each element 13 is reinforced at the curved portion 17 by stitched-on material. The reinforced, stiffened portions 17 are attached by ties 26, Fig. 4, to beams 25 attached by ties 27 to a drum 28 mounted on the shaft of a reversible electric motor 29. One beam 25 is provided for each skirt element. Flexible strips 34, attached to the vehicle body 11, support the upper edges of the curved portions of the skirt elements, each element also being releasably attached at its upper, inner corners to the vehicle body at 33. Vehicle supporting cushion air is supplied through a duct 20, the cushion being contained by the sidewalls, the above described skirt and by a bagtype inflatable skirt with its own air supply at the stern of the vehicle. A stability sensing device 32, such as an accelerometer, controls the electric motor 29, so that the stiffened portions 17 of the skirt members may be moved towards or away from the drum 28 to vary the vehicle supporting area of the cushion and to change its centre of pressure, thereby countering pitch of the vehicle. Another embodiment has the skirt members pivoted to the vehicle in place of the flexible arttachments 34, so that the electric motor 29 pivots the stiffened portions 17 of the skirt members instead of displacing them linearly, Fig. 7 (not shown). In a further embodiment both pivotal and linear motion are combined, Fig. 8 (not shown). Alternatively the skirt members may depend from a bag-type skirt, cushion gas being supplied through holes in the bag, which holes also have the ties connecting the skirt member beams to the electric motor passing through them, Fig. 9 (not shown). To prevent the U-shaped skirt elements scooping up water when the vehicle reverses, perforated panels may be fitted across the interiors of the elements to give a flattened D- shape. The invention may be used to trim the vehicle when it is loaded; in non side-wall vehicles it may be used to control roll as well as pitch. Electronic sensing means may be used to detect waves or surface irregularities as the vehicle approaches them and to displace the skirt appropriately prior to the vehicle reaching such obstruction.

Title: Discrete fourier transform computer
IPC: G06G7/19
Filed: 1976-08-09
Abstract: 1523838 Discrete Fourier transform computer COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL SA 9 Aug 1976 [13 Aug 1975] 33070/76 Heading G4A A discrete Fourier transform computer based upon a known realization of Goertzel's algorithm (see Digital Processing of Signals by Gold and Rader) which algorithm computes the Fourier transform coefficients singly using a filtering technique, is characterized in that (a) the computer can be put into a set-up mode in which in response to input values of cos 2 #/N and sin 2 #/N it computes and stores all the values cos 2 #r/N and sin 2 #r/N, r = 0, 1, ..., N-1, for subsequent use in computing the Fourier transform and (b) the number N of points in the Fourier transform can easily be changed. In accordance with Goertzel's algorithm the rth Fourier coefficient Xr is computed (1) by causing multipliers 5, 6 and 7 to multiply by 2a r , -a r , and b r  respectively, where a r  = cos 2 #r/N, and b r  = sin 2 #r/N, (2) by entering, at E, from an N-stage circulating register 11, the N samples x(nT), n = 0, 1, ..., N-1, and (3) by extracting at terminals S1 and S2 the real and imaginary parts of Xr immediately after the last sample x#(N-1T) is processed, the values occurring at the terminals S1 and S2 while the earlier samples are being processed being ignored. This process, a "compute cycle" is repeated for all values of r for which Fourier coefficients are required, the values of the sine and cosine functions being stored in registers 9 and 10 and being extracted when required. In accordance with the invention, during a "set-up" cycle, starting with registers 9, 10 and 11 cleared to zero, the multipliers 5, 6 and 7 are set to multiply by 2a 1 , -a 1 , and b 1  respectively where the values a 1  = cos 2 #/N and b 1  = sin 2 #/N are provided from some source not shown. A unit impulse I(nT) n = 0, 1, 2, ..., N-1, where I(nT) = 0 except when n = 0, is then applied to the entry point E and the system is allowed to run. It can then be shown that as the N samples (I/nT) are entered, the values cos 2#r/N and sin 2#r/N appear consecutively on terminals S1 and S2 respectively. These values are stored in registers 9 and 10 and subsequently used in "compute cycles". By arranging that the registers 9, 10 and 11 have a selectable number of stages N, and by choosing the initial values cos 2 #/N and sin 2 #/N appropriately, the Fourier coefficients can be computed for an arbitrary number N of points.

Title: Improvements in gas turbine power plants
IPC: F02C7/16
Filed: 1953-12-02
Abstract: 737,648. Gas turbine plant. AKT.-GES. FUR TECHNISCHE STUDIEN. Dec. 2, 1953 [Jan. 13, 1953], No. 33535/53. Class 110 (3). In a gas turbine plant in which the working medium flows in a closed circuit including a heater, a turbine, a cooler and a compressor and the turbine has an inner and outer casing, working medium is taken from the circuit at a point where the temperature is lower and the pressure higher than the inlet temperature and pressure of the turbine and led through the space between the inner and outer casings to a labyrinth packing of the turbine where one part is directed towards the turbine rotor for cooling it and protecting the shaft from the hot working medium and the other part is expanded in a part of the labyrinth packing to a point of  lower pressure. In the plant shown, working medium compressed in a compressor 6 is heated by the turbine exhaust in a heat exchanger 1 and then further heated in a heater 2 before expansion in a turbine 4. The turbine exhaust after passing through the heat exchanger 1 is cooled in a cooler 5 and then passed to the compressor 6. The turbine 4 comprises an outer housing 8 and an inner housing 10 separated by a space 9 which is connected by a duct 16 to a point 17 where the working medium is at a lower temperature and higher pressure than the working medium entering the turbine 4 at the inlet 11. The space 9 exhausts through a port 18 formed between the two parts 14, 15 of the labyrinth packing. A part of the cooler working medium flows through the part 14 of the packing towards the turbine rotor 12 to cool the rotor. The remainder of this working medium flows through the part 15 to a space 19 which is connected through a duct 20 with a point 21. The space 19 is sealed by labyrinth packing 22. If desired, the duct 20 and packing 22 may be dispensed with and the cooler working medium passing through the packing 15 passed to atmosphere. The outer housing 8 is maintained at such a temperature by the cooler working medium that it is capable of taking up the stress produced by the internal pressure. The outer housing 8 at the low pressure end is in direct contact with the exhaust working medium. As the temperature at the point 17 is substantially equal to the temperature, the entire outer casing is maintained at the exhaust temperature. A duct 24 connected to the compressor discharge may also be connected to the space 9. A valve 23 may be used to control the flow through the duct 24 and so control the temperature of the working medium flowing to the space 9. The space 9 may be connected at a plurality of points to the point 17.
