Abstract: A programmable clock (60) includes a memory for storing times, dates and messages for subsequent read-out and display in providing a reminder of a birthday, anniversary, doctor's appointment, meeting, etc. The clock pro-vides a user with a visual display of stored reminder messages, as well as an indication of the content of the reminder message. The reminder clock also includes a speaker and an audio recorder for providing a reminder message in the user's own voice, as well as a printer for providing more extensive rem-inder messages as well as a list of all stored reminder messages. The remin-der clock makes use of any one of several analog and combined analog and digital time displays (86, 72, 73) which are easily read and understood, in-cluding a display presenting an analog representation of hours (80) and a di-gital display of minutes (82). Various audio and/or video alarms are pro-vided to indicate the read-out and display of a reminder message. An elec-tronic pendulum is provided to indicate proper operation of the reminder clock as is a calendar (22) indicating the days and times when stored remin-der messages are to be recalled from memory and displayed.

Title: Method of making wood composites treated with soluble boron compounds
Inventor: HSU WU-HSIUNG E
IPC: C08L61/06
Filed: 1993-05-05
Granted: 1995-06-27
Abstract: A novel method of producing a wood composite treated with a soluble boron compound is disclosed.  Either a phenol-formaldehyde resole or novolac type resin can be used as the binder for a wood furnish.  The wood furnish is surface treated with either the resole type resin or novolac resin together with a water soluble boron compound whereafter the surface treated wood furnish is formed into a mat and then consolidated in a press.   When novolac is used as the resin, the consolidation takes place under sufficient pressure, heat and time in order to cure the novolac type resin and to form the wood composite. Optionally, the curing of the novolac resin can be promoted by injecting the compressed mat with steam, rather than by means of heated press platens.   However,  if a resole type resin is employed as the binder, while in its consolidated condition, pressurized steam is injected into the consolidated mat for a time sufficient to cure the binder and form the composite.  The wood composite so produced and which contains the soluble boron compound, exhibits acceptable internal bond strength, and due to the inclusion of the boron compound, renders the composite less susceptible to biological attack and more fire retardant than conventional composites employing phenol-formaldehyde alone as the thermosetting adhesive.

Abstract: The present invention discloses a method for preparing the inorganic hardenable slurry and the use of same in the solidification of wastes,  In addition to water, the essential parts of the slurry are inorganic components including borates, cement-base powder and other additives such as magnesium oxide, gypsum and silica.  The slurry is low in viscosity before solidification and flows freely, and within approximately 30 minutes after preparation the slurry becomes hardened into a highly solidified substance,  The solidification of the slurry is resulted mainly from reaction of borates and the cement-base powder and to obtain a best result the weight of borates must be the same as that of the cement-base powder or even higher than the weight of the latter.  The solidification mechanism differs entirely from the simple hydration reaction that brings about solidification of cement.    The present invention also teaches a method for solidifying wastes with this hardenable slurry, i.e. to proceed solidification by admixing the various radioactive or non-radioactive dry and wet wastes with the hardenable slurry, or by burying waste pellets with the slurry.  The solidified waste form thus obtained has a higher strength and the volume efficiency of the solidification is 2.5 to 10 times that of the conventional cement solidification. When applied to the solidification of low level radioactive wastes, the present method produces especially a tremendous economic efficiency.
