Abstract: A gas turbine engine combustor, eg of annulur combustor configuration, has air inlets, typically in the dilution zone, which incorporate vortex generators operative to trip the inlet jet flow causing stabilizing vortex flow at the lateral edges of the jet. The vortex generators can comprise an inwardly directed abrupt change of section between forward and rearward parts of the air inlets. The rearward section of the air inlets can have a configuration operative to reinforce the jet stabilizing effect of the vortex flow. The combustor exhibits improved uniformity of jet and crossflow mixing.

Abstract: A cylinder block (bc) which constitutes a main part of an engine block is formed of a cylinder barrel assembly block (7), a skeleton-like frame surrounding the outer periphery of the cylinder barrel assembly block (7) integrally therewith and a plate-like-rigid film member (9), wherein a fluid passage is disposed in the skeleton-like frame (8). The skeleton-like frame is integrally joined to the outer surfaces of left and right side walls of the assembly block along the axis of a crankshaft and comprises a plurality of crossbeam bone members (15), longitudinal beam bone (16) members and post bone members (17) which have rigidity and are unitarily assembled into a three-dimensional latticework structure. A cylinder head (Hc) is superposed and integrally coupled to the deck surface of the cylinder block (bc) and a lower case is integrally coupled to the lower surface of the cylinder block, lateral outer surfaces of the block and lower case along the crankshaft axis being formed flush with each other in parallel with the cylinder bore axis. The lower case (CL) comprises a lower case frame of three-dimensional latticework structure and second rigid film members disposed at least on the lateral outer surfaces of the lower case frame along the crankshaft axis. Moreover, with use of a plurality of oil pan-mount­ing bolts, the lower case is tightened and secured to the lower surface of the cylinder block and an oil pan (Po) is   floatingly carried on the lower surface of the lower case via resilient members. The cylinder block has at its one end surface along the crankshaft axis a square, transmission mating surface and a divergent bulged portion which extends from a rear part of the cylinder block in a fan-shape toward the transmission mating surface. Thereby, the structure of engine block is simplified and vibration and noise of the engine are reduced. The rigidity of engine is enhanced while suppressing the weight increase to a minimum.

Abstract: The invention resides in the fact that, in each transmitter 2 associated with a detector 1, the alarm signal is transmitted a first time without delay, via the connection 20, then a second time after a certain delay of a variable duration via the delay line 4. The delay depends on the relevant transmitter. Thus, when an alarm signal appears simultaneously in a number of detectors-transmitters, it is transmitted at different instants. The invention is applicable to security systems. <IMAGE>

Abstract: This invention relates to an apparatus for measuring a velocity distribution inside a fluid by a pulse Doppler method using an ultrasonic wave or electromagnetic wave. An observation wave is transmitted to and received from a fluid and a reflection echo from the fluid is received to determine its Doppler frequency. The observation wave scans inside a predetermined tomographic plane and the Doppler velocity distribution in this tomographic plane is determined. Since this Doppler speed distribution is only the component in the direction of the observation wave, it is accumulated in the direction perpendicular to this observation wave direction and is further differentiated again in the observation wave direction so as to calculate the component in the perpendicular direction. If the observation wave is an ultrasonic beam, the velocity distribution of the blood inside the heart can be inspected.

Abstract: A phase shifter, without a phase limit, for the radio frequency band permits two RF signals to be added in the correct phase. The phase shifter, without a phase limit, is implemented in slot- and strip-line technology in such a manner that, for the phase shifting, the RF signal to be shifted is separated by a longitudinal coupler (K1) into two signals, offset through 90 DEG , and the signal components (x- and y-signals) produced in this way are shifted through 0 DEG  and 180 DEG  via a slot-line arrangement which is connected in, having two semiconductor elements, for example PIN diodes (Dx1, Dx2; Dy1, Dy2) which are connected, in DC terms, in antiparallel. The two signal components are then added with a phase shift (Wilkinson coupler) of 0 DEG by means of a 3dB coupler. <IMAGE>

Abstract: A levelling control arrangement for an RF transmitter circuit which additionally compensates for filter ripple, i.e. frequency dependant power variations caused by the filter (7) disposed between a transmitter amplifier (3) and an antenna (8). The forward and reflected power is sampled by a dual directional coupler (5) between the amplifier (3) and the filter (7). Signals V fwd  and V rev  are thus obtained indicative of the forward and reflected power levels respectively. The reflected signal V rev  is subtracted from the forward signal V fwd  at comparator (22) and the difference signal V diff  is compared with a reference signal Vref at comparator (25) to produce a signal V c  which is used to control the gain of the amplifier (3) in such manner that the power developed by the amplifier increases as the signal V rev  increases and vice versa. To protect against excessive reflected power levels a limiter (23) may be included which causes the power developed by the amplifier to be reduced only if V rev  exceeds a pre-set threshold.

Abstract: A method for determining the frequency of an analogue input signal. Spectral components of the signal are obtained from data sampled from the signal by carrying out a transform. The spectral component having the largest spectral valde is identified, and the frequency of the signal is assumed to be the frequency of the spectral component having the largest spectral value. The spectral components are obtained using a set of functions described by a matrix in which each matrix element is a single bit number. The spectral components are accumulated by performing addition and subtraction operations, avoiding the need for relatively complex multiplications. The signal may be converted to a rectangular wave which is applied to each of an array of EXCLUSIVE-OR gates. Each gate also receives inputs corresponding to the matrix elements of a respective function. The gates may be connected to an array of up-down counters which accumulate the spectral values from each of the data samples.

Abstract: In the upper part of a drainage tube (3), two types of air outlet openings (8 and 15) are uniformly distributed over the entire length of the tube in the direction of the longitudinal axis of said tube (3), one type (15) of air outlet openings (8 and 15) being disposed at the top of the drainage tube. Said openings (8 and 15) are used to supply flushing air to the granular filter mass (2). As a result of suitably distributing the total cross section of the air openings (8 and 15) over the two types, a pressurised gas cushion which ensures a uniform distribution of the flushing air over the entire tube length is produced on feeding flushing air into the upper part of the tube (3) in this way. The openings (15) in the top region ensure virtually complete venting of the drainage tube (3) after flushing with an air component. This prevents an inadequate venting of the filter mass (2).
