Abstract: A B S T R A C T A disposable syringe for medicinal or similar purposes, of the type, which may be used once only. The piston rod is coupled to the piston through a lost-motion connection. The piston and the piston rod are initially positioned one relative to the other such, that they are - as seen in the moving out direction - rigidly coupled. In the end portion of the cylinder turned away from the injection needle means are provided adapted to lock the piston and the piston rod in said rigid coupling position along a part of the suction stroke length corresponding to the length of said cylinder end portion, such that upon initiating the injection stroke a certain lost motion of the piston rod relative to said piston will occur only after the area comprising said locking means has been passed through, said lost motion causing said piston to become in a state, from which a next effective suction stroke is impossible.

Granted: 1992-01-14
Abstract: ?     ABSTRACT     Synthetic raw materials are used to prepare a sintered refractory body consisting essentially of cordierite having 47.5 to 56 weight percent SiO2, 31 to 40 weight percent A12O3, 12 to 19 weight percent MgO, and 0.15 to 1 weight percent CaO, the body having a flexural strength of at least 138 MPa (20,000 psi). The cordierite body with respect to impurities, has less than 0.3 weight percent total alkaline earth metal oxides other than MgO and CaO, less than 250 ppm Na2O, less than 150 ppm K2O and less than 500 ppm transition metals on the oxide basis.  Thus, the cordierite of the invention has very low impurity levels yet good sinterability and, hence, high strength.

Abstract: ABSTRACT OF THE DISCLOSURE     A computerized music notation system comprises a first keyboard having pitch keys, a second keyboard for entering relative rhythm codes representing the relative proportions by which the entered pitches and other rhythm types divide a beat and a terminator code to mark the end of each beat, and a computer executing a processing program for generating output music notation in beat units based upon the pitch data and the rhythm data.  The pitch and rhythm data sets are independent of each other.  The computer processes the pitch data assigning pitch names in the selected key of music, and the rhythm data in beat units by assigning computed fixed duration values to the rhythm types in accordance with the selected time signature.  The pitch and rhythm data are combined and processed for output with other notation features, such as staff lines, stems, flags, beams, articulation marks, etc.          Since the rhythm codes represent the relative spacings of the rhythm elements in beat units, they facilitate translation of the notation into a different time signature.  The system is connectable to a display, permanent storage, a printer, an optical scanner, a synthesizer and/or other input coding or music output devices.

Abstract: ABSTRACT     A process of refining  zinc  oxide  from roasted  zinc sulphide bearing concentrates comprises leaching the concentrate in  an  aqueous  sulphur  dioxide  solution  under  controlled conditions  providing  selective  separation of  zinc  from  other elements  contained  in  the  concentrate.  The  zinc  bisulphite solution so obtained is separated from the remaining solids and is  heat  treated,  preferably with  steam, to  precipitate  zinc monosulphite crystals, possibly after first adding zinc dust to the solution to cement out residual copper and cadmium. The zinc monosulphite is then separated from the solution, possibly washed with water, and calcined to yield purified zinc oxide.

Title: Infant security system
Inventor: WOLK BARRY M
IPC: G08B13/14
Filed: 1988-12-07
Granted: 1992-08-04
Abstract: ABSTRACT       An infant security system is disclosed which includes a transmitting device that generates at least two uniquely coded signals and is disposed around the leg or ankle of infants in a hospital maternity ward, children's ward or the like.  An activated magnetic strip is also attached to the transmitting device.  An associated receiver is placed, for example, on the cart containing the infants' crib or bassinet which will typically be close enough to the infant so that it is well enough within the range of the transmitter.  Every few seconds the RF transmitter transmits a coded RF pulse.  If an infant with an attached RF transmitter is removed by some predetermined minimum distance from its associated RF receiver or if the RF transmitter becomes inoperative or is shielded, then the RF receiver will not receive the transmitted coded signal which will trigger an alarm.  If a kidnapper attempts to detach the RF transmitter from the infant, a switch is opened which in turn causes the RF transmitter to emit a second coded signal. Upon detection of the second coded signal, an alarm in the RF receiver will be triggered.  An alarm is also triggered if an activated magnetic strip on the RF transmitter is transported through a maternity ward exit point.

Title: Moving magnet type meter
Inventor: SATO KOICHI
IPC: G01R5/16
Filed: 1989-06-29
Granted: 1992-08-18
Abstract: Abstract In the moving magnet type meter of the present invention, the coil mounting portions of a bobbin body are projected outwards in a generally arched shape on the central side to form circular arc-like or inclined surfaces.  The bobbin body can be made to resist external pressure induced by the mounting of coils thereon and can be prevented from being deformed.  Further, the upper portion of a movable magnet is centrally formed with an upwardly projecting shaft support portion for supporting a pointer shaft.  A thrust bearing portion is formed in the lower surface of an upper bobbin body portion in an opposed relation to the upper end face of the said shaft support portion through a predetermined gap.  The pointer shaft can be formed in the shape of a straight rod without forming a reduced-diameter portion serving as a thrust bearing, therefore the fabrication of the pointer shaft is easy and it is also possible to maintain the strength of the pointer shaft itself.

Abstract: A unitary dispending closure having a lid mounted on a closure part or base in such a manner that the lid will automatically move toward either a closed or an opened position when it is released after being manipulated to any position between these two positions can be constructed so as to utilize the resiliency within a "live" hinge to provide the force necessary to move the lid. In any position intermediate these two positions the hinge connects to the lid and closure part or base so that contact between the lid and closure part causes temporary deformation of the hinge. As a result of the resiliency of the material in the hinge such temporary deformation is adequate to move the lid as described.

Abstract: A security thread (1) for a bank note comprises a discontinuous magnetic thread (3) which has binary coding, the binary values being denoted by the presence or absence of bit lengths of thread. The coding employed is repetitive, comprising alternating termination segments (4) and word segments (5). The length of a termination segment in terms of bit lengths is less than the length of a word but is greater than the maximum length permitted within a word of bits which have the same binary value as the bits in a termination segment. The invention provides resistance to false readings and, by varying the parameters of bit length, word length, length of the termination segment and otherwise, a multiplicity of different codings having the same general format.
