Title: Magnetic disk apparatus
Inventor: OKUTANI KATSUHIRO
IPC: G11B25/04
Filed: 1991-06-10
Abstract: A magnetic disk apparatus wherein magnetic disks and magnetic heads are housed in a case (1), prevents waterdrops from being generated on the surface of the magnetic disk (3) and avoids the magnetic head being attracted to the magnetic disk during the nonoperating period of the apparatus in one embodiment by installing in a case a fan (6) for circulating the air in the case during the suspension period of the apparatus, thereby making the temperature difference smaller between the air and the surface of the magnetic disk. In an alternative embodiment a magnetic disk apparatus wherein magnetic disks and magnetic heads are housed in a case, avoids the magnetic head being attracted to the magnetic disk even in the case where waterdrops are generated on the surface of the magnetic disk by rotating the magnetic disks during the nonoperating period of the apparatus to make the magnetic head lift off from the magnetic disk. <IMAGE>

Title: Multiple tires on a single wheel.
Inventor: OZAKI YASUSHI
IPC: B60C23/16
Filed: 1991-10-16
Abstract: The inner spaces of two tires 3a, 3b, disposed adjacently parallel to each other on a single wheel 1, communicate with each other by way of airflow piping 8 including a pneumatic pressure control valve 7. When one tire leaks because of a puncture, the pneumatic pressure of the other tire also decreases, thereby allowing the driver to notice the puncture. If the punctured tire leaks slowly, air is supplied to it by the other tires via tapered grooves (20) - (23) (Fig 3) in valve body 10, tending to equalise the pneumatic pressure so that the driver can drive for a certain time and be free from any serious accident that may occur when he is unaware of the puncture. If the punctured tire leaks rapidly, the pressure control valve closes when the pressure difference reaches a given value. so that the vehicle can still be driven on the other tire. Lights 40, 41 linked to the pressure control valve indicate whether a tire is leaking and which tire it is. <IMAGE>

Title: Seamless pythons
Inventor: LEONARD DAVID GEORGE
IPC: F16L11/22
Filed: 1992-02-01
Abstract: A python being an elongate bundle of parallel tubes encased in a foam sheath, is produced by inserting a pre-wrapped elongate bundle of parallel tubes into an open end of an elongate foam sheath (12). Alongside the leading end of the bundle there is also introduced one or more air supply tubes (13) providing a stream of lubricating air to assist the smooth passage of the bundle along the sheath. The air tubes (13) and the sheath (12) are clamped (as at 17) to prevent them from advancing with the bundle. The bundle travels through and beyond the length of foam sheath until the trailing end of the bundle has reached the leading end of the sheath whereupon the process is repeated several times until the entire length of the tube bundle is encased within aligned lengths of foam sheathing. The python is then completed by butt joining the individual lengths of sheath and by helically wrapping the entire structure with a protective strip of self-adhesive material. <IMAGE>

Patent GB-2272354-A (GB)
Title: Method and apparatus for crop spraying
Inventor: BENEST ROGER SYDNEY
IPC: A01M/
Filed: 1992-07-23
Abstract: A dropleg row crop sprayer (12) senses boom height and tilt from ground-contacting droplegs (46) signalling through potentiometers (74, 76) to a boom control mechanism (84). The droplegs follow crop row wandering through a driven carriage (44). Dropleg attitude is assisted by a cam control system (94, 96). The boom (20, 21) floats through a spring suspension system (128, 138) and is damped by frictional abutment of the boom portions (20, 21), thereby permitting a single actuator (106) to control attitude. A lost motion linkage (126) protects the actuator (106) from snatch loads. Spray control is effected by use of microdroplets discharged from the droplegs (46) below the row crop leaf canopy which protects the droplets from wind turbulence, while electrostatic charges and droplet-energising air flow act to assist crop coating. Where conventional spray droplets are used, the spray direction is fore/aft of the row to minimize ground speed effects. <IMAGE>
