Abstract: A gas equalizer device for use in conjunction with a reciprocatory pump located downhole in a wellbore. The device of the present invention avoids a condition commonly known in the pumpjack art as "fluid pounding", which is brought about when compressible gases accumulate in the working chamber of the downhole pump. The gas equalizer device of the invention includes a pushrod having a marginal end reciprocatingly enclosed in a slidable manner within a housing which is mounted to the usual traveling valve cage of the downhole pump. The pushrod is alternately moved from an extended into a retracted position each upstroke and downstroke of the pump. The free terminal end of the pushrod is arranged to engage the ball check valve of the traveling valve assembly as the pump commences the downstroke. This unseats the ball, thereby allowing any accumulated gases to escape from the variable pump chamber.

Abstract: Infectivity and replication of influenza viruses in successive numbers of cells of the same liquid cell culture is assured by including a protein hydrolyzing enzyme in the culture during virus incubation. Technique overcomes "one-step growth cycle" of virus and allows commercial influenza vaccine production from liquid cell cultures instead of from more costly embryonated chicken eggs. Resulting vaccine is thus substantially free of egg proteins.

Abstract: A boat hull having a two-stage flow chamber. The first stage flow chamber starts about amidships as a V-shape fairing upward at a shallow angle and flattening out about halfway to the stern. The second stage flow chamber starts at the end of the forward flow chamber curving upward at a greater angle than the first stage and curving downward slightly at the stern. The second state flow chamber has an inverted V-shape portion connected to the bottom by a pair of narrow sidewalls spreading slightly outward. The forward flwo chamber delivers water to the aft flow chamber free from turbulence. The propeller is disposed in the aft flow chamber and splayed slighly to port. Water exits from the aft flow chamber with minimum turbulence and cavitation.

Abstract: A self-sufficient pocket for concealing a small item, the pocket being attachable to the inner surface of an undergarment or garment where it is accessible only to the wearer thereof. The pocket is composed of a rectangular back sheet marginally sealed to a larger rectangular front sheet except at the top side to leave a top entry to form an open pocket for receiving the item. The back sheet is centered with respect to the front sheet to define a frame-like border thereon which is coated with a layer of pressure-sensitive adhesive. When the loaded pocket is pressed against the inner surface of the garment, this action also serves to close the pocket. When the pocket is thereafter stripped off the garment, the pocket is then open and the item can be removed from the pocket.

Abstract: A tool for setting threaded anchors, having an elongated body with a longitudinal bore and a threaded shaft received in the bore and projecting beyond both ends of the body to form a nut engaging end and an anchor engaging end. The anchors to be set include an anchor frustum having a longitudinal threaded bore, surrounded by a soft sleeve. A pinway is formed in the body communicating with the bore, and a retaining pin, in engagement with the threaded shaft, projects laterally through the pinway, for preventing relative rotational motion between the threaded shaft and the body while allowing relative longitudinal motion. A nut engages with the nut engaging end of the shaft. The method of setting such an anchor is to insert the anchor, attached to the end of the tool, into a hole where the anchor is to be set. The nut is then rotated with respect to the shaft, while preventing the rotation of the shaft and the body, so as to draw the frustum into the soft sleeve until the anchor is affixed within the hole.

Abstract: For a simple adjustment, suitable for automation, of the axial play between the rotor (1, 2) and the stator (5 to 8) of a miniature electric motor, at least one bearing (3) is axially moved relative to its bearing sleeve (51) in the end bell (5) and is fixed in its adjustment position by deformation of the bearing sleeve in a form-locking manner. For axial fixation, especially when used for drives with large axial loads, a thrust shoulder (511, 512) is formed after the axial play is adjusted for the axial contact of the adjusted bearing (15) from the bearing sleeve (51) by hot molding, ultrasonic heat deformation. Alternatively, precut tabs may be formed on the sleeve by embossing to form a thrust shoulder.

Abstract: The method and apparatus for pickup of packets with a varying number of stamped laminations, for instance for stators of electrical machines, from a lamination stack (98) compressed under tension between clamping plates (24, 100) is so performed that the first packet half of laminations are always rotated by 180.degree. before the entire lamination packet is measured off and picked up. Therefore, two different stops (42, 44) are needed for measuring off the first half and then the entire lamination packet for each packet height. In order to dispense with the necessity of having to exchange, when changing the packet height, the one clamping plate which heretofore was designed with various stops, the lamination packets with a differing number of laminations are always mounted between the same clamping plates (24, 100) and supported together with the one clamping plate (24) on axially adjustable stops (42, 44). Consequently, the device features axially adjustable stop (42, 44).
