Title: Method of making balloon retention catheter
Inventor: TENNERSTEDT MILTON RICHARD
IPC: B29C49/00
Filed: 1990-04-18
Abstract: An expandable section plastic tube having utility, for example, in inflatable balloon section catheters, and a method of making the same. The tube formed of thermoplastic material is inserted in a wall defining member, such as a mold (44), having an enlarged section (42) surrounding a portion of the tube. The tube portion is then heated to a thermal plastic temperature and is expanded into the enlarged section by a sudden application of pressure resulting in a thinning of the tube wall in the expanded area. Thereafter, the tube is cooled and removed from the mold, in the making of a catheter, one section of the tube to one side of the expanded area is inverted and drawn into the section of the tube on the other side of the expanded area whereby the expanded area forms a balloon end at one end of the telescoped tube sections. <IMAGE>

Title: Apparatus for descrambling a television signal
Inventor: HARADA KIMIHITO
IPC: H04N7/171
Filed: 1990-08-21
Abstract: Apparatus for descrambling a scrambled television signal in which a horizontal synchronising signal section and a vertical blanking section of a video signal are suppressed and a key signal is superimposed on an audio signal at a position corresponding to the horizontal synchronising signal section, and which contains timing mode data indicating a time difference between the key signal and the horizontal synchronising signal section, is provided with means for preventing "buzz" noise in the reproduced sound and image deterioration due to white level non-restored pulses which occur before and after the vertical blanking interval (VBI). Specifically an extension control signal (9) for the VBI is generated which rises at a timing delayed from the last key signal Di before the VBI by 64 mu sec plus the time difference between the key signal and horizontal synchronizing signal section and falls at a timing delayed from the first key signal after lack of the key signal detection by an extension period of the horizontal synchronizing signal section plus the above time difference. <IMAGE>

Patent GB-2259802-A (GB)
Title: Musical instruments
Inventor: YEADON JOHN CHRISTOPHER
IPC: G10D7/12
Filed: 1991-07-27
Abstract: A chromatic harmonica is tuned to a mode of limited transposition instead of a diatonic scale. In a preferred embodiment (Fig 2a) adjacent blow notes are three semitones apart: changing from blow to draw raises the note by a semitone, and operating the slide raises blow and draw notes by a semitone. Most notes are found in the same position as on the standard chromatic harmonica. This makes it relatively easy for the experienced player to change over to the present invention from the standard instrument. Many other combinations of adjacent note intervals, blow/draw interval (from 1 DIVIDED 4 to 1 tone) and slide change interval (from 1 DIVIDED 4 to 1 tone) are disclosed. A keyboard for musical instruments may also be arranged according to the second mode of limited transposition. There are also disclosed methods of tuning the reeds of free-reed musical instruments by the addition of fusible material, solder or adhesive. <IMAGE>
