Title: Fuel element casing
Inventor: ZUR CAPELLEN HEINZ MEYER
IPC: G21C3/12
Filed: 1982-06-07
Abstract: There is proposed a casing having easy-to-manufacture spacers. Projections (4) are pressed out of a hexagonal casing (t) in the region of the longitudinal edges (3) of the casing in the spacer plane, without the thickness of the wall of the casing being changed to any great extent thereby. The projections (4) extend generally parallel to the sides (2) of the casing (1) and thus form two contact surfaces for adjacent casings on each side of the casing in the spacer plane. The sides (2) of the casing (1) are less expanded in the area of the spacer plane than the edges (3). Particularly if the projections are rounded here, or pass into the remaining parts of the casing tube by means of transitional sections, the proposed device enables, in spite of simple manufacture and great rigidity, the individual casings to be drawn-out without difficulty even if the adjacent casing is slightly distorted. <IMAGE>

Title: Pressure control valve for clutch or brake
Inventor: SCHELE FRANZ
IPC: F16D48/02
Filed: 1982-08-06
Abstract: A pressure control valve (39) is inserted in a fluid controlled system, in particular for the operation of fluid controlled clutches and brakes, in which increasing pressure is used for the actuation of the pressure controlled cylinder of the fluid controlled element (8), and in which the actuation of the cylinder takes place at a considerably increased speed with respect to conventional devices. For this purpose fluid is supplied to the pressure control valve (39) via a supply line (15) with the movable valve elements (9, 25) initially in positions as shown, but flow is then reduced by fluid acting on a control surface (20) of the element (9) which is supplied via a feedback control line (17) incorporating a flow-restricting diaphragm (18). Another control line (22) incorporating a flow-restricting orifice (23) supplies fluid to the control piston element (25) which acts on the element (9) via a spring (26). A fluid return line (29, 30) is also provided, by which the pressure in line (22) is relieved until a land (28) of the element (9) cuts off communication between those lines. <IMAGE>
Patent GB-2125247-A (GB)
Title: Compressive interferometer
Inventor: SIMPSON STEPHEN HENRY WATTS
IPC: G01S3/48
Filed: 1982-08-06
Abstract: Input signals from spaced aerials 25, 26 are mixed 27, 37 with chirp signals from generators 29, 39. The resultant bursts are fed via circulators 31, 32 to a dispersive delay line 33, passing contemporaneously therethrough in opposite directions, to provide compressed inputs to a phase discriminator 36 via the circulators 31, 32. Signals representing the sine and cosine of the phase difference between the received signals (and hence direction of reception) are output at 23, 24. The use of the single delay line 33 avoids errors due to temperature variations between the matched lines used in the prior art (Fig. 1). Switches may be used instead of circulators (Fig. 3). <IMAGE>

Title: Detecting the instant of arrival of a seismic wave
Inventor: SEEMAN BRONISLAW
IPC: G01V1/42
Filed: 1983-09-23
Abstract: In a seismic measuring method, a plurality of shocks are transmitted from a source (30) at the surface (32) of the ground to cause seismic waves to propagate through the ground to be picked- up by a geophone (20) located down a borehole (11). Traces of the signals received by the geophone are recorded. A magnitude which is a function of the recorded traces is calculated for each instant following the initial shock, and the statistical distribution of said magnitude at each of said instants is examined. A threshold probability is determined, above which said distribution is considered to correspond to the existence of coherence between the different recorded traces for said instant. The recorded traces are examined together in order of increasing time. When, for example, three consecutive instants all give a distribution above said threshold, it is assumed that the recorded signal corresponds to the first arrival of the shock wave at the geophone, and the instant of first arrival is consequently determined. <IMAGE>
