Abstract: Resin peptides useful in the preparation of peptides having biological activity, and particularly such resin peptides containing R-CH.sub.2 -Phe-Glu at one end of an amino acid chain, R being the resin and Phe and Glu being the residues of the amino acids phenylalanine and glutamic acid; and processes for the preparation of such resin peptides. Resin peptides are disclosed which contain amino acid chains identical with the amino acid chains of natural peptides having biological activity. Other resin peptides are disclosed which contain amino acid chains in which the amino acid residues differ in kind and sequence from amino acid chains of natural biologically active peptides but from which peptides having biological activity may be derived.

Abstract: A process for preparing sliced dried beef in which beef is ground into chunks which are mixed with a curing ingredient, stuffed into fibrous casings and cured.

Abstract: A video production module including a truck. The electronic equipment is contained in rack frames one of which is attached to the frame of the truck, and other rack frames are hingedly mounted on each side of the one rack frame so that they swing about their hinges into a compact arrangement without exposed connecting wires. The module includes a production arm which is pivotally mounted at one end to the truck and which connects with a desk at its other end so that when the arm is raised to vertical position it brings the desk into a protected position above the rack frames.

Abstract: A toggle type of fastening device which includes a plate in one piece having an opening therein, the edges of the opening being engaged by a screw, the ends of the plate being bendable inwardly toward each other against spring tension to allow the plate to pass through a wall opening and being resilient so that when the plate has passed through the wall opening the ends spread out and prevent the plate from being drawn back out of the wall opening. Another feature is the provision of a rib for added strength and yet another feature is the threaded engagement of the screw with the plate at different levels. The process for manufacturing such a device includes the step of forming the opening in a piece of metal, forming a rib about the opening and then treating the formed piece to make it resilient after it has been deformed.

Abstract: A seating and hand rail structure which is foldable from a normal seating position into a folded storage position in which the rail as well as the seating structure is in a compact arrangement.

Abstract: A method and apparatus for determining and displaying without invasion into the vascular system the instantaneous rate of blood flow, the stroke volume during a pulse or cycle, and the cardiac output over a time period. The system involves an arrangement of electronic units through which a signal representing impedance of a section of a living body is passed in a special order and which results in instantaneous and continuous indication of blood flow characteristics through this section.A principal feature of the system resides in the provision of two electrical channels one of which contains an electronic divider and the other an electronic differentiator both of which channels are connected with a multiplier which multiplies the signal from one channel with the signal from the other channel to produce a signal representative of the rate of instantaneous blood flow through the body section being tested.

The plane of the top of the cooking plate is above the plane of the top edge of the outer rim so as to permit a spatula to be inserted under the crepe with its blade parallel with the top of the plate, and to permit trimming of the edges of the crepe with the end of the spatula. A downwardly extending rim is provided on which the griddle may rest, and an opening is provided in the outer rim through which crumbs may be passed from the channel out of the griddle.
