Patent EP-0013972-A1 (EP)
Inventor: JAMES KENNETH ALLAN
IPC: G02B6/28
Filed: 1980-01-22
Abstract: An apparatus for improved efficiency coupling of optical energy is disclosed. Coupling of the optical energy from one or more input fiber optic cables (30, 32) to a larger number of output fiber optic cables (34) is accomplished by means of a mixing rod (28) having input and output cross-sectional areas substantially matched to the input and output coupled fiber groups, respectively, and having appropriate tapering of the rod crosssection therebetween. 
     As a result of tapering the mixing rod, the coupler provides gradual reflection angle reduction that permits retention of the transmission system numerical aperture despite random refractive bending due to surface imperfections at the mixing rod/fiber coupling junction. In addition, an input coupling junction of prior art straight mixing rod couplers is obviated in the tapered mixing rod coupler, thereby eliminating a source of undesirable coupling loss.

     R is an aliphatic linking group of from 1 to 8 carbon atoms and 0 to 4 heteroatoms which are oxygen, nitrogen or sulfur, having from 0 to 1 site of ethylenic unsaturation as the only aliphatic unsaturation, any nitrogen being present as tertiary amino or amido and any sulfur being present as thio;   X and Z are taken together to form oxo or imino or can each be hydrogen;   A is hydrogen, hydroxy, alkoxy of from 1 to 6 carbon atoms, or an antigenic poly(amino acid) or polysaccharide, or an enzyme;   n is on the average from 1 to the molecular weight of A divided by 1000, with the proviso that n is 1 when A is hydrogen, hydroxy or alkoxy,   is, or is a percursor of, conjugates used in the detection of β-adrenergic blocking agents; antigenic conjugates are employed for the preparation of antibodies and enzyme conjugates as detectors. A detection method using the latter is also claimed.

Abstract: AA first low-current discharge circuit applies low-current power to the machining gap between wire WIR and workpiece WK to trigger a discharge. A second high-current discharge circuit applies high-current power to the machining gap to produce a main discharge for machining the workpiece WK. 
     The first low-current discharge circuit comprises low-current source V 1 , a small discharge capacitor C 1  and a transistor Q 1  for controlling discharge of capacitor C 1  across the machining gap. 
     The second high-current discharge circuit comprises a high-current source V h , a large discharge capacitor C h , and a transistor Q h  for controlling discharge of capacitor C h  across the machining gap. 
     The first and second discharge circuits are arranged so that the first low-current discharge circuit supplies power with the wire WIR positive relative to the workpiece WK and the second high-current discharge circuit supplies power with the wire WIR negative relative to the workpiece WK. 
     This reduces undesirable electrolytic action on the workpiece and facilitates increased cutting speed.

Abstract: The arrangement serves to produce grooves of a certain depth, in particular pattern defects, in the interior of elongated hollow spaces in metal pieces (3), e.g. in the interior of pipes. It consists of a long, preferably cylindrical, supporting body (22) which is equipped at one end with a circular saw and has at its other end a drive shaft and in its interior transmission elements for connecting the drive shaft to the circular saw, and of an adjusting device (1) by means of which the depth and length of a groove can be set and which acts on the rear part of the supporting body (22) located outside the hollow space, and of a drive (21) frictionally connected to the drive shaft. A method of operating the arrangement consists in the fact that the metal piece (3) is mounted in an electrically insulated manner and that the zero point of the adjusting device, upon contact between the saw and the metal piece (3), is signalled by a light signal from an indicating lamp via a non-volatile switch with the indicating lamp connected downstream.

Abstract: The preamplifier for a voltage measuring instrument provides for noninteracting span and zero adjustments. Two voltage follower circuits are used and employ differential amplifiers (16) and (42) with negative feedback. The first produces a current througt the output resistor (58) of the preamplifier proportional to the voltage being measured while the second produces a current through the output resistor proportional to a fixed reference voltage + REF. The proportionality of the first amplifier (16) is adjustable by a potentiometer (20) which modifies the feedback. This adjusts the span. The proportion of the reference voltage used as input to the second amplifier (42) is adjustable by a potentiometer (36) to adjust the zero. The feedback for the second amplifier is via a potential divider (46,48) which may be connected to + REF to achieve negative or positive zero offsets.

A predefined temperature may be set by the thermal elements prior to the manual setting of the rotary machine so that the temperature of the frame and/or rotating member(s) can be controlled to compensate for wear of the rotating member(s) in machines wherein such member(s) encounters wear over operating time.
