Abstract: A multi-function wallet comprising a leather cover, at least two strips, a sub-wallet, a plurality of notebook papers, a string, a bead chain, a hook and a fastening hook; the string is to pass through holes on the leather cover, the strips, and the sub-wallet so as to fasten all the aforesaid part into one piece; both ends of the string are fastened the hook and the bead chain together. The fastening hooks are fixedly connected with the bead chain. The strips mounted on the leather cover and the sub-wallet are used for clamping banknotes and notebook papers respectively. The inner side of the leather cover has a large bag for storing ID card or the like; the inner side of the inner leather sheet of the sub-wallet has a partition flap and a lid flap; the partition flap can be opened partially, and used for storing ID card or the like. The inner side of another inner leather sheet has several coin bags for storing different coins.

Abstract: A mattress having channels on the bottom edge along the four sides thereof respectively aligned with channel plates, said channel plates having clamps secured by screws along inner peripheral edges thereof for clamping down a linen sheet permitting it to be covered over the mattress and firmly retained in place. Peripheral projections with raised portions are respectively made on said channel plates to increase friction force in securing a linen sheet to said mattress.

Abstract: A safety pin comprised of a pin having one end pivoted to a pivot bearing at one end of an elongated base plate above a face board, and a pointed opposite end releasably retained to a pin holder at an opposite end of said elongated base plate, wherein said pin holder comprises two side springs for holding the point of said pin, and a front guard for protecting the point of said pin, said side springs having L-shaped pawls releasably retained together for locking up the point of said pin. Squeezing said two side springs inwards causes said L-shaped pawls to move apart for passing the point of said pin; releasing the pressure from said two side springs causes said L-shaped pawls to retain together in locking up the point of said pin.

Abstract: A method for purifying hemoglobin, mixed with other proteins is described, wherein the mixture is contacted with an ion exchange matrix so that the hemoglobin is adsorbed to it. The matrix is washed to remove unadsorbed components, and the hemoglobin is then selectively eluted using a ligand which specifically binds the hemoglobin causing it to desorb from the matrix. The method can also be used to effect reduction of methemoglobin to hemoglobin on an ion exchange matrix followed by selective elution to achieve purification. The method can also be used to purify methemoglobin.

Abstract: A safety bank note holder for carrying personal bank notes, comprising a rectangular plate and a rope, said rectangular plate being formed with two holes respectively at two ends thereof, permitting the rope to be conducted therethrough to wind up the plate so as to let bank notes bound up between the plate and the rope. A retaining ring can be pre-arranged in the pocket of a user's clothes to connect the rope, whereby the bank notes are securely placed in the pocket, and can be easily pulled out for use.

Abstract: This invention relates to a steering lock for an automobile. In particular, one utilizing a U-shaped hook to clip a steering wheel and insert with a latch rod into the U-shaped hook so as to lock the steering wheel to protect the automobile from being stolen.

Abstract: This application discloses flexible homogenous and smooth compositions whch consists essentially of an interdispersion of low density polyethylene and polychloroprene ingredients and at least an effective amount of fibrous polytetrafluoroethylene interdispersing agent effective to homogeneously blend said ingredients.

Abstract: A process for producing ethanol from plant biomass is disclosed. The process in cludes forming a substrate from the biomass with the substrate including hydrolysates of cellulose and hemicellulose. A species of the fungus Paecilomyces, which has the ability to ferment both cellobiose and xylose to ethanol, is then selected and isolated. The substrate is inoculated with this fungus, and the inoculated substrate is then fermented under conditions favorable for cell viability and conversion of hydrolysates to ethanol. Finally, ethanol is recovered from the fermented substrate.

Abstract: This application discloses cables insulated with a flexible homogenous and smooth composition which consists essentially of an interdispersion of low density polyethylene and polychloroprene ingredients and at least an effective amount of fibrous polytetrafluoroethylene interdispersing agent effective to homogenously blend said ingredients.
