Very costly professional-level judgments needed to comply with scientific and statutory restrictions on hazardous-waste segregation, shipment and disposal are collected cumulatively in a database for a very large number of hazardous waste materials. Many of these materials are statutorily designated or scientifically recognized, or both, as posing a significant physical danger to humans, other organisms, or the ecosphere generally. Later many consignments of particular materials are received (or identified before receipt, in a batch mode of operation) and classified very inexpensively--using nonprofessional-level personnel--by reference to the computerized database. Reversion to professional-level judgments occurs only if a material not previously encountered is received. Each consignment of each material is classified and handled consistently with all other consignments of like material, and in accordance with the professional-level judgments embodied in the database. The system automatically establishes subsequent routing and handling, and generates all labels, regulatory reports and inventories; and also makes possible detailed tracing, tabulation of hazard characteristics by specific areas within storage facilities, and even retrieval if desired for recycling or reconfiguration.

Headset for electrodes

The invention disclosed by this application relates to a novel method of processing sinterable powders into sintered ceramic products. This application also relates to novel forms of aluminum oxide, hydroxylapatite, and tricalcium phosphate ceramic products prepared in accordance with the method of this invention, as well as novel intermediate products useful to prepare the novel ceramic products of this invention.

A headset is provided for holding electrodes against a subject's head for extended periods of time which has several pairs of support poles or rods whereon several flexible electrode supporting bands attach that allow variable placement and holding of various electrodes in various regions on the head. The regions for placement are the occipital, the central and the frontal regions of the head. The electrode supporting bands are elastic and are attached by hook and eye means to opposing rods so that the bands can be slidably and flexibly adjustably mounted on the headset apparatus. This allows tension holding the electrodes against the subject's head to be adjusted for an optimum balance of comfort and contact.

A core form is disclosed for casting a structurally reinforced concrete structure for use on a slab with an outer container form having rigid walls extending vertically comprising a casting core positioned internal the outer form and having vertically extending resilient walls defining an within contiguous core wall. The walls of the outer form and the walls of the casting core are spaced apart to define a mold cavity therebetween. A form base supported by the slab is positioned within the mold cavity to releasingly support the concrete structure to be formed and cured within the mold cavity. The walls of the casting core include an upper and lower periphery such that in use the lower periphery abuts the form base to seal the concrete internal the mold cavity relative the periphery and form base. The internal contiguous core wall is retractable to enable the placement of the reinforcing structure within the mold cavity. Prior to pouring concrete into the mold cavity the walls of the outer form and the contiguous core walls are positioned and braced. After the concrete has cured the internal contiguous core wall of the casting core is retracted and the walls of the outer form are positioned to enable the cast reinforced concrete structure to be removed. A means for extending and retracting the walls of the casting core during the pouring and curing of the concrete and for bracing the walls of the casting core when the concrete is cured are disclosed. A particular outer form is also disclosed.

Ceramic process and products

A moldable bone-implant material containing between about 65%-95% hard filler particles and a binder composed of between about 35%-5% of a biocompatible, biodegradable, thermoplastic polymer which has fluidic flow properties at or below about 60.degree. C. One preferred binder is polylactic acid having a molecular weight between about 400 and 5,000 daltons, and a preferred hard filler is hydroxylapatite. In use, the material is warmed to a temperature which allows molding, and the bone site is filled with the moldable material, which then forms a contour-fitting, semi-rigid implant. The implant retains its contour fit and acquires a rigid final state as the binder in the implant is gradually biodegraded and replaced through tissue ingrowth from the surrounding bone site.
