Abstract: The design, and synthesis of peptide-based molecules termed helizymes which possess catalytic activity are described herein The catalytic molecules of the invention comprise a number of amphiphilic helical peptides, which interact via hydrophobic interactions and which are bonded at their carboxyl ends to a multifunctional base. Active site residues functional for catalysis are positioned within or at the N-termini of the helical peptides. The helizyme molecule adopts a conformation in aqueous medium such that a substrate binding pocket is formed and such that functional active site geometry results from the association of the helical peptides Specifically exemplified helizymes possess specificities and at least one catalytic activity of chymotrypsin, trypsin and acetylcholine esterase.

Abstract: A thin film heterojunction solar cell and a method of making it has a p-type layer of mixed ternary I-III-VI.sub.2 semiconductor material in contact with an n-type layer of mixed binary II-VI semiconductor material. The p-type semiconductor material includes a low resistivity copper-rich region adjacent the back metal contact of the cell and a composition gradient providing a minority carrier mirror that improves the photovoltaic performance of the cell. The p-type semiconductor material preferably is CuInGaSe.sub.2 or CuIn(SSe).sub.2.

Abstract: A process for separately removing zinc and iron from acidic wastewater. The process involves adding alkali metal hydroxide to the acidic wastewater (below about pH 4) to achieve a first pH of about 4.8 to at most about 5.4 and precipitate an iron hydroxide-containing precipitate at this pH. The precipitate from the wastewater is separated and then additional alkali metal hydroxide is added to achieve a second pH in the range from about 8.8 to about 9.4. A zinc hydroxide containing precipitate forms at this second pH and is then recovered by filtration.

Abstract: A padded toilet seat lid is made by magnetically induction welding to the upper surface of a plastic lid shell, a plastic frame which surrounds a cushion providing the padding. The frame traps a peripheral margin of the cushion against the upper surface of the lid. The cushion is also secured to the lid by a pressure-sensitive adhesive. Welding of the frame to the lid is accomplished in a special fixture that supports the lid and cushion upside down.

Abstract: A thin film I-III-VI.sub.2 based solar cell having a first layer of copper indium gallium selenide, a second layer of cadmium zinc sulfide, a double layer of zinc oxide, and a metallization structure comprised of a layer of nickel covered by a layer of aluminum. An optional antireflective coating may be placed on said metallization structure. The cadmium zinc sulfide layer is deposited by means of an aqueous solution growth deposition process and may actually consist of two layers: a low zinc content layer and a high zinc content layer. Photovoltaic efficiencies of 12.5% at Air Mass 1.5 illumination conditions and 10.4% under AMO illumination can be achieved.

Abstract: The substitution of the L-Pro at the 7-position of the peptide hormone bradykinin or other substituted analogs of bradykinin with an aliphatic, cyclic or aromatic amino acid of the D-configuration converts bradykinin agonists into a bradykinin antagonist. The invention further includes additional modifications at other positions within the novel 7-position modified bradykinin antagonists including C-terminal and N-terminal extensions and replacement of arginine in the one and nine positions which increase enzyme resistance, antagonist potency and/or specificity of the new bradykinin antagonists. The analogs produced are useful in treating conditions and diseases of the mannal and human body in which an excess of bradykinin or related kinins are produced or injected as by bites into the body.

Abstract: A hinge arrangement for the lid and seat of a toilet is disclosed. Hinge pins extend outwardly from lugs on a bowl unit of the toilet through corresponding openings in flanges on the seat and lid and are provided with cam surfaces co-operating with corresponding surfaces on the lid. The co-operating cam surfaces generate frictional forces when the lid is raised so that the lid will tend to stay in a position to which it has been raised. The cam surfaces also define open and closed detent positions in which the lid is positively retained. The seat can be hinged freely when the lid is raised and is trapped against the bowl unit when the lid is closed.

Abstract: A portable toilet of the type having a waste holding tank which is separable from a bowl unit of the toilet. The tank includes a vent for permitting entry of air to the holding tank during emptying thereof. This avoids surging of the contents of the tank during emptying, assuring a smooth flow of the liquid and minimizing splashing. In a preferred embodiment, the vent takes the form of a sleeve projecting upwardly from the holding tank and defining a vent passageway, and a cap on the sleeve which can be manually raised to open the vent passageway but which is automatically depressed to close the vent when the bowl unit is secured to the holding tank.

Abstract: A flush toilet primarily for use in recreational homes and vehicles is described. A swing drop valve mechanism is used to open and close the outlet of the toilet bowl efficiently and without abrading the seal between the valve and bowl outlet. A flush water inlet valve is mounted in a compartment at the rear of the toilet for easy access for maintenance and is readily removable from the toilet using a minimum of tools. Flushing of the toilet is initiated by a foot pedal connected to the valve mechanism and water inlet valve by cables.

Abstract: The invention is a process for recovering phosphorus value from magnesium pyrophosphate containing filter media in the wet superphosphoric acid purification process. The invention comprises treating the filter cake with a salt to remove the adhering phosphoric acid without solubilizing magnesium acid pyrophosphate. The filter cake, after phosphoric acid removal, can be utilized as commercial or technical grade magnesium acid pyrophosphate.

Abstract: A two-piece portable toilet having sight gauges for the flush water reservoir and holding tank. The sight gauge takes the form of a translucent plastic insert having a highlight formed by a diametral groove which permits the liquid level to be clearly ascertained. The inserts are sealed by induction welding in openings in the wall of the reservoir and holding tank respectively.
