Abstract: A drill bit for drilling through sticky formations, such as chalk or marl, comprises a plurality of waterways 4 for transporting drilling fluid and rock flour to the gauge of the bit. These waterways have in downstream direction gradually increasing cross-sectional areas A, the increase of size of said areas along the length of a waterway being at least substantially proportional to the squared radius r thereof from the central axis 10. In this manner the rock flour velocity remains equal or decreases in downstream direction in the waterways so that the risk of rock flour accumulation and compaction is reduced.

Abstract: A method for selectively etching higher aluminum concentration AlGaAs in the presence of lower aluminum concentration AlGaAs or GaAs, preferably at room temperature. The AlGaAs is first cleaned with a solution of NH₄OH and rinsed. The AlGaAs is then etched in a solution of HF. If photoresist is used on the AlGaAs, the photoresist may first be baked to increase the adhesion of the photoresist to the AlGaAs and to "toughen" the photoresist to reduce undercutting thereof. Agitation is applied to the AlGaAs or the etchant to assist in the uniform etching of the AlGaAs.

Abstract: The invention relates to a device for the manufacture of stranded conductors by Roebel transposition of profile wires with a rectangular cross-section with a guide for the profile wires conveyed in two parallel stacks. The device is formed from side parallel guide surfaces and latches, which are offset through 90 DEG  with respect to said surfaces and one of which is provided per stack, the two latches being located diametrically opposite one another and being displaceable in parallel, in opposing directions, cyclically, and of slides which can move at right angles to the longitudinal extent of the stranded conductor for displacement in opposite directions of in each case one profile wire from a (lacuna) on the adjacent stack, while bending the profile wire. The slides are supported opposite one another in the other diagonal, in the same way as the triggers. The device furthermore comprises a control device for synchronisation of the cyclic operation of the drives for displacing the triggers and slides. The invention is characterised in that each slide (5) has allocated to it on the opposite side of the stranded conductor an opposing holder (8) which is offset with respect to the slide in the conveyance direction (9) of the stranded conductors and is supported displaceably in the opposite direction thereto, at right angles to the stranded conductors, and is driven in synchronism with the movement of the slides and triggers. <IMAGE>

Abstract: A liquid crystal light valve cell has two optically different states switchable therebetween by DC voltage in response to laser beam. A ferroelectric liquid crystal layer (6) is sandwitched by a pair of front and rear alignment layers (5a-5b) to establish the two stable states of bistable state in the ferroelectric liquid crystal layer. The threshold voltage values of bistable state depend on temperature of the liquid crystal. A front electrode layer (2b) is disposed on the front alignment layer (5b). An optically reflecting layer (4) is disposed on the rear alignment layer (5a). A laser beam absorbing layer (3) is disposed on the reflecting layer (4) and absorbs thermal energy of laser beam (9) irradiated. A rear electrode layer (2a) is disposed on the laser beam absorbing layer (3) in cooperation with the front electrode layer (2b) to apply the DC voltage such that effective DC voltage is applied across the liquid crystal layer (6) to thereby effect the switching between the two stable states.

Abstract: A marine seismic surveying method utilizes two vertically spaced marine streamers (18,20) each having a plurality of seismic detectors (22,24) contained therein, and a seismic energy source (16) positioned at or near the surface (38) of a body of water (10) to generate seismic waves (30,32,34) which propagate into earth formations (26,28) below the water and reflect back up to be detected at each streamer. Seismic waves also reflect from the water/air interface back down toward the streamers. The seismic waves detected at two selected vertically displaced seismic detectors (22,24) are combined to form a sum signal which is then combined with a scaled time integral of a difference signal to form a resultant signal which preserves either the upgoing or downgoing seismic waves. In a preferred embodiment of the present invention, the sum signal and the integral signal are both filtered to remove DC bias and low frequency components prior to the combination. Additionally, the time integral of the difference signal is preferably scaled by balancing the power therein with the power in the sum signal, thereby automatically adjusting for variations in detector spacing which may occur. In one embodiment of the present invention, the upgoing signal and downgoing signal are time shifted and combined to maximize the resultant signal-to-­noise ratio.

Abstract: A method for the manufacture of silicone rubber moldings comprises the preparation of a silicone rubber composition by blending an organoperoxide having an activation energy of 25 to 41 kcal/mol into a semicurable organopolysiloxane composition whose main component is organopolysiloxane having organoperoxide-crosslinkable functional groups. The silicone rubber composition is made into a particulate form and heated at a temperature below 100 degrees Centigrade to produce a semicured, particulate molding material which retains the activity of the organoperoxide and which contains residual crosslinkable functional group on the organopolysiloxane. Subsequently a mold is filled with the molding material and the mold material is completely cured at a temperature of at least 100 degrees Centigrade under the application of pressure. The method is particularly useful for automatic molding methods.
