Abstract: A disposable urethral catheter assembly includes a flexible bag in which a number of chambers are defined by barriers. In an upper chamber, a catheter is contained in a sterile environment. When the catheter is inserted through the urethra into the bladder, the fluid flows into the bag through the upper chamber and into a lower sample chamber, excess fluid being collected in the upper chamber. After catheterization, a one-piece element which provides a sealable passageway through the first barrier between the upper and lower chamber can be readily closed by manipulation through the wall of the bag and thus isolate the sample in the lower chamber. The upper chamber, its contents and the catheter are separated from the sealed lower chamber and discarded. The lower sample chamber which provides a sterile environment for its contents can then be sent to a laboratory for analysis and culture.

Abstract: Disclosed herein is an improvement in and concerning a tape reel of the type used in a video tape cassette and comprising a hub, flanges disposed one each at the opposite axial ends of the hub, and a small protuberance formed at the center of at least one end surface of the hub and adapted for engagement with a matching socket in the tape reel holder of the cassette housing, which improvement resides in the construction of the tape reel wherein a member for carrying the aforementioned small protuberance is produced, independently of the flanges and the hub, of a resin resistant to abrasion in a design such that the assemblage of the reel is accomplished by fixing the flanges onto the hub through the medium of the small protuberance carrier member.

Abstract: A device for braking the motion of the float of a float type liquid-level gauge used with a liquid container, comprising a casing, a vane member disposed in the casing in such a manner as to produce a motion relative to the casing, a fluid placed to fill the inner space of the casing now containing the vane member and retaining an extra space for permitting the relative motion of the vane member, and a path formed in the casing to permit flow of the fluid inside the inner space of the casing during the aforementioned relative motion of the vane member inside the casing. In actual use, the casing is fixed in position and the vane member is connected with a member adapted to move in conjunction with the float of the float type liquid-level gauge. When a sudden, momentary displacement occurs in the liquid level in the liquid container with which the liquid-level gauge is used, the float kept on the liquid surface by buoyant force tends to follow the displacement.

Abstract: A holder comprises a leading portion adapted to retain in position thereon an electronic/electric part, a base portion adapted to be secured to a distributing base panel and a shank portion serving to interconnect the leading portion with the base portion and having a hole pierced therethrough for guiding the lead wire of the electronic/electric part to the lower side of the base portion. The holder permits a given electronic/electric part which is set in position on the leading portion to be securely retained at a distance from the distributing base panel, with the base portion fastened to the base panel and the lead wire of the part passed through the hole and connected to the prescribed point of connection on the base panel.

Abstract: Fastening device of plastics material for a round hole, designed to receive a screw enabling mounting with a high gripping torque and this even in thin sheet metal. It includes a principal element capable of becoming clipped in a round hole of a support and a complementary element which is engaged in the upper portion of the first element. A mounting screw passes through the element and becomes self-tapping in the lower portion of the body. The advance of the screw causes, at the same time, the descent of the wedge and the reascent of the low portion of the principal element, which results in gripping expansion of the whole within the hole. The invention can be used for the mounting of any parts by means of a screw in a member clipped in a round hole with high gripping torque.
