Abstract: ABSTRACT OF THE DISCLOSURE            A non-insulated printed circuit board jack includes an outer stepped drawn shell member, and a stamped contact member disposed within the shell for receiving an electrical conductor.  The shell member has at one end a minor diameter portion which is freely receivable in an aperture in the printed circuit board.  Intermediate its length the shell includes an integral flexible retaining portion which is generally polygonal in cross-section having alternating corner portions and side portions.  The corner portions are resistively receivable in the printed circuit board aperture such that when the shell retaining portion is inserted into the aperture the inner circumference of the aperture forces the corner portions of the shell in-wardly, and causes the outward expansion of the side portions, whereby the shell retaining portion tends to conform to the configuration of the printed circuit board aperture.  By this arrangement, an interference or snug fit is achieved between the connector and the printed circuit board.

Abstract: ABSTRACT OF THE DISCLOSURE A device for taking from a flowing suspension a sample-flow representative of said suspension comprises a first chamber arranged to receive the flowing suspen-sion, said first chamber communicating via a weir with the upper part of a second chamber having first and second openings arranged at the bottom thereof for removing the sample-flow and the remaining part of said suspension respectively. The openings are separated from each other by partition walls which extend trans-versely of the weir over the whole length of the second chamber and communicate with a respective outlet. The openings for receiving the said remaining part of the suspension communicate with the associated outlet via a substantially U-shaped passage and a second weir which is located substantially on the same level as the weir of the first-chamber. In order to prevent blockage of the U-shaped passage while maintaining the requisite precision of the device, at least one of said partition walls exhibits means for maintaining communication between said U shaped passage and the sample-flow outlet in a region located beneath the uppermost level of the connection between the two legs of the U-shaped passage.

Abstract: BINARY ELECTROEXPLOSIVE DEVICE          Abstract of the Disclosure Disclosed is a binary electroexplosive device including an explosive lead and a pyrotechnic explosive which may be selectively positioned to initiate the explosive lead upon combustion of the pyrotechnic material.  The pyrotechnic material is contained in an initiator assembly which may be inserted within a combination socket and housing which also holds the explosive lead facing the pyrotechnic ma-terial but spaced therefrom.  Insertion of the initiator assembly within the socket completes electrical connec-tions between a power source and a bridgewire within the initiator assembly embedded in the pyrotechnic material.         In a particular embodiment shown, the electroexplosive device is utilized as a blasting cap for a well jet per-forating gun wherein the gun may be completely assembled with the exception of the insertion of the initiator assembly in the socket.  At the well site, the electrical system may be tested for shorts or other malfunctions by a combination test and insertion tool, whereby the initiator assembly may then be seated to arm the electroexplosive device.

Abstract: ABSTRACT OF THE DISCLOSURE          The preparation according to the invention comprises resorcinol and at least one carbon black in homogeneous distribution.  The preparation is preferably in the form of beads or granulates.  The preferred granular form is attained when the resorcinol has an average particle size of 0.10 to 0.40 mm or is reduced to this average particle size during the production process.  Furnace blacks having a specific particle surface area of approximately 40 to 120 square metres per gram, an average primary particle size of 20 to 45 nm and a dibutyl phthalate absorption of 45 to 130 millilitres per 100 grams are preferred as carbon blacks.  The preparation according to the invention preferably has a weight ratio of carbon black to resorcin between 70 to 30 and 30 to 70.  The upper limit of this weight ratio is 95 to 5.  The process for producing the resorcin-filler preparation is also disclosed.  Preferably two process steps are carried out namely a) first a treatment of the resorcin-ol which is in form of the usual platelets or small lumps, jointly with the powdered  carbon black in a high speed mixer for several seconds and b) then preferably in another low-speed mixer while the product formed assumes a bead-like shape if the above condition of average particle size of the resorcinol is maintain-ed.  The resorcinol can also be applied in the molden form.  For the use of the liquid resorcinol the high speed mixer has a heating device and, when required a cooling device, as well as a propeller type or a rough mixing tool.  The use of the preparation of rubber adhesion mixtures for improving the adhesion of rubber vulcanizates on metal, textiles or glass fibre structures is also disclosed.
