Patent GB-2049856-A (GB)
Title: Tube and nipple coupling
IPC: F16L33/207
Filed: 1980-05-02
Abstract: A locking device is used for locking a resilient tube 4 to a nipple provided with at least one flange 1b. The device comprises a sleeve 3 which is separate from the nipple and which can be threaded over the flange 1b of the nipple. The sleeve is applied on the nipple and after that the tube 4 is threaded over the flange 1b and in between the inner wall of the sleeve 3 and an outer wall of the nipple. Upon applying a force which tends to separate the tube and the nipple, the sleeve is actuated to a longitudinally displaced position and in this position, together with the flange 1b, prevents the separation of the tube 4 and the nipple by clamping the end of the tube 4. The tube 4 is forced on to the nipple and, inter alia this forcing provides enough sealing between the tube 4 and the nipple against a media which is conducted inside the mentioned components when the media pressure is small. If the media pressure increases so it separates the tube and the nipple, the sealing is provided by means of the sleeve. An O-ring (6, Fig. 1c) may be placed at the bottom of the sleeve. <IMAGE>

Title: Method and apparatus for dividing a track on a magnetisable disc into sectors
IPC: G11B20/12
Filed: 1980-06-17
Abstract: Method and apparatus for dividing a track on a magnetizable information storage disc into sectors by writing sector identification information into the track. In order to optimize the storage capacity of a track on a magnetizable information storage disc the track is first filled with information bytes in response to the occurrence of the leading edge of an index pulse (a) derived from the disc in such manner that a predetermined number of bytes fill a portion (ix) of the track, followed alternately by sector identification bytes and further bytes defining the data field of the relevant sector in portions SK and DT respectively until the final group of sector identification bytes has been written into portion SKn, followed by further bytes into portion z until the leading edge of the next index pulse occurs. The (positive or negative) difference between the total number of bytes in the portions z+ix and the number of bytes in each of the data field portions (DT) is then determined and the write operation is then repeated in the same track with the number of bytes written in the data field portions modified in accordance with the difference determined, so that the difference is distributed uniformly over the various data field portions. The write operations are controlled by apparatus comprising counters which address a read-only memory containing the information bytes, an arithmetic unit for determining the difference, and a store storing the modified number of bytes to be written to define each data field.

Patent GB-2126806-A (GB)
Title: Chopper circuit
Inventor: GURWICZ DAVID
IPC: H02M3/155
Filed: 1982-06-30
Abstract: Current surges in the series element (T1) of a chopper circuit supplying an inductive load (L) are reduced by the incorporation of a saturating transformer (TF) which has two counterwound windings (NL, NF) disposed on a high permeability core in series with the load (L), with the number of turns in the load winding (NL) exceeding that of the source winding (Ns), and with one side of a freewheel diode (D1) connected to the junction of the two windings. The arrangement is such that when the series element (T1) is non-conductive the load current flowing in the load winding (NL) maintains the core in saturation but when the series element becomes conductive once again and reverse current flows in the freewheel diode (D1) the transformer is taken into a high permeability region to limit the level of the latter current. <IMAGE>

Title: Fusible plug for fire safe valve
Inventor: BESON JOHN
IPC: F16K17/38
Filed: 1981-09-14
Abstract: A valve having a passageway (108, 114) through the valve housing (10) extending from the valve chamber (22) to the valve flow way (12) with a heat intensifier member (104, 204, 304) which is partially disposed in the passageway and has a bore (110, 112; 210, 212; 310, 312) registering with the passageway. A portion of the heat intensifier member projects externally of the valve housing. Either a fusible plug (118) or a fusible spacer (element (218, 318) is disposed in the bore in that portion of the heat intensifier member projecting externally of the valve housing. Fusible plug (118) blocks fluid flow through the bore, and thus the passageway, while the plug is in the solid state and permits fluid flow when it is in the liquid state due to high external temperatures. A fusible spacer element (218, 318) supports a movable plug (216, 316) equipped with seals (232, 234 or 332, 334) disposed in the bore for sealing against fluid flow through the bore and thus the passageway under normal operating temperatures. The fusible spacer element melts under high temperatures and thus permits the movable plug to slide within the bore to open the bore and permit fluid flow through the passageway. Additionally, the seals of the movable plug will disintegrate and permit fluid communication even while direct acces to the passageway is still blocked by the movable plug. These features permit the displacement of internal valve pressure to prevent damage to the valve.
