Abstract: An insulin activity messenger material and its precursor material are disclosed which have been isolated from hapatic plasma membrane cells that have been incubated with an enzyme known as a phosphatidylinositol-specific phospholipase C. The messenger material comprises a carbohydrate-based compound that exhibits the ability to modulate the activity of the insulin-sensitive enzymes pyruvate dehydrogenase, adenylate cyclase, acetyl CoA carboxylase, and low Km CAMP phosphodiesterase, and thereby effectuate the activity of insulin on the cellular level. The precursor material comprises an inositol containing glycolipid capable of phosphodiesteratic cleavage by a phosphatidylinositol-specific phospholipase C. The enzyme phosphatidylinositol-glycan specific phospholipase C has also been purified and found to participate in many of the activities identified with respect to the messenger and its precursor. Numerous diagnostic and therapeutic utilities are proposed, and testing procedures, materials in kit form and pharmaceutical compositions are likewise set forth.

Abstract: A multi-rate commodity metering system comprises an electronic key containing an EEPROM, and a meter for metering the commodity and having a receptacle for receiving the key. The meter also contains a real-time clock. The key can operate as a prepayment device, a programming device and a meter-reading device. Thus the key is taken to the commodity suppliers premises, where, in return for a payment, a credit signal representative of the payment is stored in the key. At the same time, a new program for the meter, ie new times for switching between rates and new prices per unit of commodity for each rate, together with the date and time at which the new program is to come into operation, can also be stored in the key. Then, when the key is inserted in the receptacle in the meter, the payment signal and the new program are entered into the meter. Additionally, the current set of meter readings (ie the respective readings for each rate) are read into the key, along with the date and time. The next time the key is presented at the supplier's premises for the entry of a new credit signal, the meter readings, and the date and time they were entered in the key, are read from the key.

Abstract: Process and apparatus for protecting or preserving stored commodities, in particular bulk commodities such as agricultural produce, e.g. grain, against deterioration by pest action, comprising the introduction into and maintenance in the commodity in a substantially gas-tight enclosure of a pesticidal atmosphere comprising carbon dioxide. The carbon dioxide is admitted to the bottom (3) of the storage space (1) so slowly that it spreads out as evenly as possibly in the bottom (3) region, being mixed as little as possible with the air or like gas originally contained in the storage space (1) and then displacing that air or gas progressively in an upward direction, to be vented to the atmosphere from the top of the space until the space is filled entirely with carbon dioxide in a predetermined concentration range. This range can be monitored and regulated automatically. Excess gas is vented through vent pipes (11), a slight back pressure being created by non-return flaps (14) or throttles.

Abstract: A circulation system for reducing foaming of the water or water and isopropanol wetting fluid circu­lating in a printing press, comprises a fountain pan (20) which drains into a vented return conduit (26). The vent exhausts air drawn into the circulation system to minimize foaming. A sump (36) is provided at a low point in the circulation system to prevent air entrainment in the system during start up. Wetting fluid is drawn from the sump (36) by a venturi tube (38) calibrated to provide a sufficient amount of suction that will drain the sump (36) but which will not draw air into the circulation system from the fountain pan (20). The venturi tube (38) has at least one, and preferably two orifices (52, 54) therein. The circulation system allows increased wetting fluid flow rates while reducing foaming, reducing the tempera­ture increase across the fountain pan inlet and outlet by one-half of that of prior art devices.

Abstract: A heddle frame assembly for a weaving machine comprising elongated top and bottom slats supported at each end by side members. Each of the top and bottom slats includes a symmetrically depending heddle support bar at one of its edges. The heddle support bar includes opposed heddle support surfaces which lie in intersecting planes which intersect with a vertical plane taken through the longitudinal axis of the slat at a point which is between said heddle support surface and the free end of the heddle bar. 
     An elongated heddle having a U-shaped opening on each end is used in combination with the heddle frame assembly. Each of the U-shaped openings includes two substantially parallel arms which extend generally parallel to the vertical plane of the slat and each of the arms terminate in a downwardly extending hook which converge toward the vertical plane and which mate with the heddle supporting surfaces of the heddle bar. This invention provides a heddle bar and heddle combination which tends to lock the heddle in its connection with the heddle bar when downward force is exerted on the heddle in the case of the top slat, or an upward force is exerted on the heddle in the case of the bottom slat.
