Abstract: An improved method for the rapid separation of the MM and MB creatine kinase isoenzymes is provided. The method involves the use of an ion exchange support material comprising porous glass beads having a stationary phase coupled to the surfaces thereof through an intermediate coupling agent. The intermediate coupling agent is preferably a silane coupling agent constituted by an organosilane with a silicon functional group capable of bonding to the surfaces of the glass beads and an organic functional group capable of bonding to the stationary phase. Less preferably, the coupling agent may be formed from a Grignard reagent of the formula RMgX where R is lower alkenyl and X is halogen.

Abstract: Apparatus for joining together two plies of material such as textile fabric comprising a sewing machine, contour guide means for shifting the plies as they are fed forward through the sewing machine to effect contour seaming of the plies, and a feed control clamp for clamping the trailing ends of the plies as they are fed forward. This clamp, clamped on the trailing ends of the plies, moves forward with the plies as they are fed forward. It is also automatically shifted from side to side as it moves forward to maintain the edge of the plies being sewn aligned with the contour guide means. The apparatus further comprises loading means which is adapted, while a pair of plies is being sewn, to receive the next pair to be sewn and, upon completion of sewing the first pair, to enter the next pair in the sewing machine and in the feed control clamp.

Abstract: A fireplace form comprising a firebox having an open front, a back wall, and a pair of side walls extending from the back toward the open front. The back and side walls which at least partially converge in upward direction form a main flue outlet generally at the top of the firebox for communication with a chimney flue. The firebox has at least one aperture therein in its back wall intermediate the bottom of the firebox and the main flue outlet. The fireplace form has ducts on the back side of the firebox in communication with these apertures and the chimney flue, these apertures and ducts constituting auxiliary flues for at least partially ducting away smoke and other products of combustion from the firebox. An outer housing surrounds the firebox and defines a chamber between the firebox and the housing for circulating fresh air over the back side of the firebox and over the ducts so as to be heated for discharge of heated air into a room.

Abstract: A rotary printer comprising a wheel having a generally cylindrical surface, and a pair of relatively thin cylindrical ring members slidably positioned side-by-side on the wheel for carrying a series of type members. A clamping member is provided on the wheel for clamping the ring members with the type members therebetween against an abutment on the wheel thereby locking the ring members to the wheel and the type members to the ring members.

Abstract: Apparatus for calculating the price of a measured length of material comprising a sensor for detecting the movement in either of two directions of a material having a length to be measured and a price per unit length. The unit price of the material is entered into the apparatus and a binary value related thereto is derived. Logic components responsive to the sensor determine the direction of material movement and provide a first signal representative of the distance the material moves in a forward direction and a second signal representative of the distance the material moves in a reverse direction. An output signal representing the total price of the measured length of material is provided in response to the first and second signals and the binary value derived from the unit price. A display responds to the output signal to indicate the total price of the measured length of material.

Abstract: A radio-frequency coupler comprising a first terminal for interconnection with a conventional automobile receiving antenna used for receiving rf transmissions within a first radio-frequency band, a second terminal for interconnection with a receiver operating within the first radio-frequency band and a third terminal for interconnection with a transceiver operating within a second frequency band different from the first band. A first rf transmission path extends between the first terminal and the second terminal and a second rf transmission path extends between the first terminal and the third terminal. A first resonant circuit is connected in the first rf transmission path and tuned to pass rf transmissions in the first band but substantially block those in the second band.

Abstract: A swivel connector assembly for mounting a lighting fixture or the like comprising a body member having a generally spherical surface portion, an opening through the body member at the center of this spherical surface portion, and a swivel member having a generally spherical surface portion engaging that of the body member for swinging, sliding movement relative thereto. The swivel member has a stem which extends through the opening, this stem being adapted to have a length of conduit or the like secured thereto. The swivel member further has a passage therethrough for reception of one or more wires which pass through the conduit so as to supply power to the lighting fixture. The connector further has a pin and slot arrangement for limiting rotation of the swivel member about its longitudinal axis relative to the body member so as to permit the conduit to be threaded into he swivel member and to prevent twisting of the wires.

Abstract: Apparatus for validating a card having positioned thereon a plurality of redundant encoded blocks of data readable by moving the card past a reader and for controlling the movement of such a card whose validity is to be determined. A card transporter moves a card along a predetermined path. A reader senses each block of data on the card as it moves forward along the path from an entry position to a dwell or escrow position and supplies an electrical signal representative of the data in each block. A card validator responsive to this signal compares data derived from at least one block thereof with a preselected set of data in making the validity determination. The validator includes circuitry for combining the data from at least one block with a prior set of data to produce a stored resultant set of data, and for comparing it with a preselected set of data and for supplying an indication of card validity if these sets of data are identical.
