Abstract: ABSTRACT OF THE INVENTION A container assembly which is especially adaptable to form a final presentation enclosure is constructed from a flat blank of material.  The flat blank is provided with a plurality of fold lines forming a bottom wall, side walls, and top wall portions which act in conjunction with one another to enclose a space. The side walls are connected by joining portions constituting bellows-type folding members.  The container is constructed in accordance with the normal hand movements of a person assembling it, wherein the joining members are initially easily folded inwardly thereby drawing up the respective side walls to which they are attached.  The natural grasping movement of the hands is then used to complete assembly.   The container does not utilize tabs, glue or other fastening means normally associated with a variety of containers.  The top walls are formed so as to be exposed at the top of the container to allow securing of the top wall portions by any suitable means.  There is also provided a variable volume container by means of the joining members which extend into the interior of the container.  The joining members act to center and protect a smaller item within the container or can be completely moved to make available the total volume of the container.

Patent CA-2055092-A1 (CA)
Title: Organometallic containing mesophase pitches for spinning into pitch carbon fibers
Inventor: ROMINE H ERNEST
IPC: C10C3/02
Filed: 1991-11-07
Abstract: An improved process is disclosed for producing a unique metals-containing anisotropic pitch suitable for carbon fiber manufacture.   Soluble,  aromatic-orgarnometallic  compounds are added to a carbonaceous feedstock which is substantially free of mesophase pitch and the resulting composition is heat soaked to produce an isotropic pitch product containing mesogens  and soluble, aromatic-organometallic compounds.   Next,  the pitch product is solvent fractionated to separate mesogens which contain  metals  from  the  organometallic  compounds.     The metals-containing  mesogens are heated to a temperature sufficient to cause fusion to produce a metals-containing  mesophase pitch.       In another method, the carbonaceous feedstock is heat soaked to produce an isotropic pitch product containing mesogens and high molecular weight,  soluble,  aromatic-organometallic compounds are added to the mesogen containing isotropic pitch product prior to solvent fractionation. Metals-containing carbon fibers  produced  from the  mesophase  pitch  exhibit  enhanced stabilization, tensile strength and modulus properties.           Alternatively, the solvent fractionation or separation is conducted under supercritical extraction conditions to produce a metals-containing mesophase pitch.  Organometallic compounds may be added to the carbonaceous feedstock either prior to or after the heat soak step.

Filed: 1990-06-13
Abstract: This invention provides a method for killing fungal cells without lysing in fermentation processes in order to prepare the fermentation mixture for processing to recover or extract an extracellularly expressed enzyme from the fermentation mixture. A preferred method of this invention comprises adjusting the pH of the fermentation mixture to less than 2.79 using a mineral acid, then adding sufficient acetic acid to the mixture to affect a substantially complete cell kill in mixture. A salt of the acetic acid can be used. The organic acid or salt can be added, then the pH adjusted to the desired level. Other organic acids can be used, in which case the pH of the mixture is adjusted to the pKa of the selected organic acid before the organic acid is added to the mixture. The method of this invention is useful for stopping the growth and killing the cells in any micro-organism, culture or fermentation such as those containing yeast, bacteria or fungi and is particularly useful in systems where it is desired to kill the cells without lysing them.
