Title: Safety sheath for needles, sharp instruments and tools.
Inventor: ORGAIN PETER A
IPC: A61M5/32
Filed: 1991-05-16
Abstract: A reusable arrangement to protect against accidental contact with the sharp surfaces of needles and other invasive medical instruments. In one embodiment, the invention comprises a collar that engages a sharp surgical instrument in advance of its sharp end. Attached to the collar by means of a hinge is a slotted longitudinal member, which swings over the sharp end of the instrument, thereby engaging either the collar or the portion of the instrument just in front of the collar and also retaining the instrument behind a keeper shelf. The keeper shelf may be engaged with the opposite side of the longitudinal member to lock this member over the sharp instrument. The longitudinal member may also be equipped with wing members to facilitate movement of the sharp instrument around the keeper shelf. In another embodiment, the locking mechanism comprises a set of flanges depending from the longitudinal member that are gripped by complementary catches on the collar when the device is placed into the closed position.

Title: Ionically cross-linked polymeric microcapsules.
Inventor: COHEN SMADAR
IPC: A61K49/22
Filed: 1991-10-04
Abstract: A method for encapsulating biologically-labile materials such as proteins, liposomes, bacteria and eucaryotic cells within a synthetic polymeric capsule, and the product thereof, are disclosed. The method is based on the use of a water-soluble polymer with charged side chains that are crosslinked with multivalent ions of the opposite charge to form a gel encapsulating biological material, that is optionally further stabilized by interactions with multivalent polyions of the same charge as those used to form the gel. In the preferred embodiment, hydrolytically stable polyphosphazenes are formed of monomers having carboxylic acid side groups that are crosslinked by divalent or trivalent cations such as Ca2+ or Al3+, then stabilized with a polycation such as poly-L-lysine. A variety of different compositions can be formed from the crosslinked polymer. In a preferred embodiment, microcapsules are made by spraying an aqueous solution of polyphosphazene and material to be encapsulated into a calcium chloride solution.

Abstract: The application describes a device for the mobile positioning of a luffing jib (1) on slewing cranes which are mainly installed in agricultural buildings (2). The device consists of two levers (4, 4a) which are arranged to oscillate, are fastened to the slewing part (5) of the crane and, likewise rotatably mounted, carry the jib (1). The drive is effected by a hydraulic cylinder (7) which, as in conventional cranes, lifts and lowers the tip (8) of the jib. In the construction according to the invention, the hydraulic cylinder (7) also brings about the oscillation of the linkages (4, 4a). The linkages bring about the lifting and lowering of the entire jib (1) as well as preliminary lifting or retraction of the jib in the direction of the tip (8) of the jib. <IMAGE>

Abstract: The invention relates to a method and to a device for recognition of defects in a drive system of a controlled series compensator (2). According to the invention, the regulation of the controlled series compensator (2) is influenced using an impedance difference value ( DELTA Z) (which is determined from a nominal impedance (Zs1, Zs2) and an effective impedance (Zi) calculated from system variables (iL, uC)) and as a function of the level of a measured line current (iL), in such a manner that the triggering in the branches is inhibited when the line currents (iL) are less than a limit value (iLG), and a triggering angle signal (S alpha S) is generated when the line currents (iL) are larger than a limit value (iLG), as a result of which the valve (Th1, Th2) can be protectively triggered. Thus, using system variables (iL, uC) of the controlled series compensator (2), defects in its drive system are detected and said drive system is brought into a state such that disadvantages for mains power supply operation are avoided, as a result of which the availability of the installation (2) and the quality of the compensation are improved. <IMAGE>

Abstract: The invention relates to an apparatus for synchronising windscreen wipers, having two separate swivel-bearing motors (M1 and M2) for driving one wiper blade each. The motors are provided with automatic zero-speed circuits (21 and 22) which have an automatic contact switch (31 and 32) which opens the zero-speed circuit when the wiper blade reaches a predetermined parking position. Each zero-speed circuit is connected in each case to earth when the automatic zero-speed switch (31 and 32) reaches the circuit-opening position. Between the two zero-speed circuits (21 and 22) sensors (R1 and R2) are provided in order to produce a control pulse when the said sensors detect a flow of current in a specific direction. By means of the control pulse, a corresponding synchronisation switch (S1 and S2) is controlled, which switch generates a short circuit in the armature of the corresponding swivel-bearing motor and keeps the swivel-bearing motor at a standstill for as long as there is a flow of current. <IMAGE>

Abstract: A simple and effective biochemical process solves the problems associated with sulfur in bitumen by removing sulfur from active participation in SOx-producing combustion reactions. In one aspect, an emulsion of bitumen and water is contacted with a microbiological desulfurization agent for a time and under conditions effective to reduce the oxidizable sulfur content of the bitumen. The preferred agents do not affect the heating value of the fuel, but selectively oxidize organic sulfur to water-soluble sulfates which can either be physically removed or chemically bound so that they do not cause SOx production. Multistage reaction is employed to enhance sulfur removal.
