Patent CA-2036793-A1 (CA)
Title: Hose clip
Inventor: STICHEL WILLI
IPC: F16L33/02
Filed: 1991-02-21
Abstract: ABSTRACT A hose clip wherein a flexible annular strap can be placed around one end portion of a hose and a relatively small portion (less than 50 percent) of the inner side of the strap is overlapped by the convex external surface of a deformable insert.  The space between the insert and the strap confines one or more springs, or one or more springs are outwardly adjacent the strap, to bias the concave internal surface of the insert against the adjacent portion of the hose.  The strap can constitute an endless ring or it can be of finite length and the hose clip then comprises a tightening mechanism for the strap.  The insert can be biased by one or more leaf springs, by one or more C-springs or by one or more coil springs.  The spring or springs can be caused to store more energy than required to maintain the hose in sealing engagement with a pipe or nipple, and the surplus energy is then dissipated as soon as the strap is placed around the hose and the tubular body is inserted into the hose. At least one end portion of the insert can be connected to the strap, and at least one end portion of the insert is slidable circumferentially of the strap.  The resistance of the insert to flexing at least matches the resistance of the strap.  The curvature of the internal surface of the insert can approximate or match the curvature of the non-overlapped portion of the inner side of the strap.

Title: Low porosity-high density refractory plug with constant flow
Inventor: ROTHROCK RUSSELL W
IPC: F27D3/16
Filed: 1991-06-03
Abstract: ABSTRACT OF THE DISCLOSURE Apparatus including a nozzle or refractory pipe lance for the secondary refinement of a bath of molten metal by the injection of a gas under pressure having one or more low porosity-high density refractory plugs which contain apertures of constant diameter.    For the manufacture of a pipe lance, the low porosity-high density refractory plugs are attached to a central tube and the integral structure coated with a wire reinforced lower grade refractory material by vibratory casting. The low porosity-high density of the refractory plugs provides a corrosion resistance to the change of the diameter of the gas nozzles and therefore produces a controlled high velocity gas stream. Generating small bubbles and maintaining the gas velocity at a high constant rate reduces erosion of the refractory material around the tip of the apparatus and extends the lifetime of the pipe lance or nozzle. As progressive refractory wear proceeds during the useful life of the pipe lance, the gas flow rate will remain constant within a closed system.

Title: Modulator using low-pass filter as delay element
Inventor: MULLER FRED-EGON
IPC: H03D9/06
Filed: 1991-09-05
Abstract: ABSTRACT A push-pull modulator stage (70) has two possible transmission paths, an electrically short path (7) and a phase delay path (6) with a phase delay element providing a phase shift of approximately 180°.  The phase delay element has the form of a low-pass filter.  In each of the two paths (6, 7) a semiconductor diode (D1, D2) is disposed in such a way that they sense the carrier (Uc) with a phase shift of 180° and, correspondinyly, switch in unison if no modulation voltage (Um) is present, thus suppressing the carrier at the signal output (3).  When a modulation signal (Um) is present, the push-pull balance is disturbed and the resistance of one of the two paths (6) becomes lower relative to the other path (7), which leads to the generation of the modulated carrier voltage (Umc).  The modulator stage (70) can also be designed as a dual modulator stage and/or can be used as a mixer stage.

Inventor: HYLL JOHN
IPC: F04D29/62
Filed: 1991-09-17
Abstract: ABSTRACT      An improved collar assembly adapted for easing the disassembly of stacked members on a shaft subjected to compressive loading is disclosed. The collar assembly includes a pair of collar members which are mounted contiguously abutting one another along a planar angulated interface. One of the collar members defines a bore therethrough configured to closely correspond to the exterior diameter or exterior configuration of the shaft in which the collar assembly is to be mounted. The second collar assembly defines a bore therethrough which is dimensioned to be substantially larger than the shaft exterior configuration in which the assembly is to be mounted. The disparity in the bore sizes permits the second collar to be displaced laterally as well as axially along the shaft with respect to the shaft and along the planar interface of the two-collar members. The two-collar members define the respective exterior engagement surface adapted to engage and otherwise abut against a member stacked on the shaft. The distance between the opposing engagement surfaces thereby adjustable dimensionally as the second collar member is displace along the surface of the first collar member. A cover, adapted to retain the two collars in alignment one with the other, is configured to be positioned about the two collars. One or more jack screws may be mounted within the second collar member to releasably retain that member in a selected orientation vis-a-vis the shaft.
