Title: Intermediate moisture vegetables
Inventor: LEWIS VICTOR MARCUS
IPC: A23B7/148
Filed: 1985-08-30
Abstract: Process for producing a plant product, which term is to be understood as covering all types of products normally regarded as vegetables including leaves, roots, bulbs, stems and immature and mature fructifications, the sweet fleshy fructifications of plants normally referred to as fruits and non edible plant material. The plant product is of intermediate moisture content which is microbiologically stable at water activity levels within the range of 0.5 to 0.85 and is free of additives used to prevent microbial spoilage.

Title: Apparatus and methods for effecting a burn-in procedure on semiconductor devices
Inventor: FRASER DOUGLAS S
IPC: G01R31/26
Filed: 1986-05-20
Abstract: Semiconductor devices (47) are mounted on cards (46) and installed on raised racks (44) extending up from a tank (38) forming a burn-in chamber. The racks are individually lowered to immerse the operating devices in a liquid medium (42) at an elevated temperature. The racks are individually accessible through aligned segments (34A-34E) of a segmented cover to reduce the intrusion of room water vapor. The temperature of the medium is maintained by pumping the medium over cooling coils (112). A lead screw (156) and lever (150) combination provide variable speed pumping, to accommodate changes in medium viscosity, from a fixed speed motor (134). The pumping also produces uniformity in the medium temperature. Vapors in the chamber are blown across acid absorbing material (226) to remove hydrofluoric acid and then across condensor coils (202). Condensed water is separated from the condensed medium in a separator (70) that has deep wells and a circuit (286) to indicate the water level. The liquid medium is returned to the burn-in chamber. A filter (62) cleans the liquid medium.

Patent GB-2219664-A (GB)
Title: Position transducer
Inventor: CHARLESWORTH FRANK DAVID
IPC: G01B7/00
Filed: 1989-06-09
Abstract: A position transducer utilizes components made of non-ferromagnetic materials, rather than the ferromagnetic materials conventionally used for such components, to avoid spurious effects caused by the temperature dependency of ferromagnetic properties. In a linear variable differential transformer embodiment 12, a non-ferromagnetic core 22 moves within a non-ferromagnetic tube 13. This movement changes the distribution of an alternating magnetic field induced at the surface 14 of the tube 13 by a coil 24, and hence gives rise to a net e.m.f, indicative of core position, in secondary windings 25, 26. Alternatively the non-ferromagnetic components may be plates (P1, P2, figure 1a) and the field may be generated by passing an alternating electric current through one plate (P2, figure 1a). <IMAGE>
