Patent EP-0181171-A2 (EP)
Inventor: HARVEY BARRY
IPC: H03M1/74
Filed: 1985-11-01
Abstract: @ A voltage reference circuit for digital-to-analog converters and the like, including an operational amplifier (4) with a feedback transistor (T1,T2) connected in a feedback circuit. A dual output buffer circuit is connected to the amplifier output, with one of the buffer outputs (T9,T1) providing the output for the reference circuit, and the other buffer output (T10,T2) connected to the feedback transistor (T1.T2). The two buffer outputs track each other in voltage, but substantially isolate the feedback circuit from high frequency transient signals on the reference circuit output line, thereby inhibiting destabilization of the reference circuit. In the preferred embodiment (Figure 4) the buffer circuit (T9, T10) is formed from a pair of matched bipolar transistors and associated current sources. A compensation circuit supplies a current to the reference circuit output which is substantially equal, but opposite in polarity, to the base current drawn by the buffer transistors, thereby reducing the input voltage offset. High frequency transient signals which do reach the feedback circuit from the reference circuit output line are mostly absorbed by capacitors in the buffer and compensation circuits.

Abstract: A drive mechanism in which the energy source drives a pump feeding two hydraulic motors (4 and 5) connected in parallel and comprising means for feeding one of the motors or both at the same time and a valve (19), which is normally closed, inserted in the feed circuit of one motor and whose opening is controlled by the pressure of the hydraulic fluid when the latter reaches a predetermined value, the said fluid pushing back a piston subjected to the action of an opposing spring, the cross-section of the said piston (23) being such that the valve remains open even if, on coupling the second motor (5), the pressure in the circuit falls to a value which is less than that which should govern at that moment. A pressure limiter (25) is inserted in the circuit and makes it possible to divert the fluid under pressure to the reservoir (6) when the pressure at the input of the said limiter reaches a value which corresponds to the desired clamping couple. <IMAGE>

Abstract: A solid phase substrate which yields soluble radioisotopically labeled products upon hydrolysis by a glycosaminoglycan endoglyco­sidase and methods of producing said substrate are comprised in the present invention. The solid phase substrate comprises glycosaminoglycan bearing labeled substances bound to amino groups. The labeled glycos­aminoglycan substrate is reductively aminated at its reducing terminal end to produce an amine-terminus. The substrate is further coupled to an amino-reactive solid matrix through its amine-terminus. 
     A method of producing the solid phase substrate comprises the steps of: at least partially N-desulfating or N-deacylating a glycosaminoglycan; labeling at least partially N-deacylated or N-desulfated glycosaminoglycan with a substance yielding detectable signals to produce labeled glycosaminoglycan; completely N-acylating the labeled glycosaminoglycan with acyl anhydride or acyl halide; reductively aminating a reducing terminal end of said labeled glycosaminoglycan to produce labeled amine-­terminal glycosaminoglycan; and coupling, through its terminal amine, the labeled amine-terminal glycosamino­glycan to an amino-reactive solid phase support to produce the solid phase substrate. 
     The solid phase substrate is usable to detect metastatic tumors by measurement of serum heparanase levels. The potential metastases of a tumor may also be determined by its heparanase levels.
