Abstract: Bei derartigen filigranen Gittern (10) für die Erforschung von extraterristischen Strahlungsquellen (XUV- und Röntgenquellen) treten bei ihrem Transport in orbitale Umlaufbahnen starke mechanische Belastungen auf, die eine Dauerbiegebeanspruchung an dem Bereich des unsteten Überganges von den Gitterlamellen (11) zum starren umlaufenden Rahmen (15) verursachen. Um diese Übergangsstelle (Pfeil) mechanisch stabiler zu machen, wird der Übergangsbereich (Pfeil) in bestimmter Weise strukturiert, und so die Bruchgefahr herabgesetzt, ohne daß die physikalischen Eigenschaften des Gitters (10) wesentlich beeinträchtigt werden. Die Struktur kann unregelmäßig oder regelmäßig sein und wird in einfacher Weise bei der photolithografischen Herstellung des Gitters (10) durch die Belichtungsmaske erzeugt.

Abstract: The present invention is directed to the preparation of ethanol by bacterial fermentation. It makes use of a microorganism capable of producing ethanol and the process is carried out in two stages. In the first stage a bacterial cell suspension is produced together with ethanol in an ethanol concentration range that does not substantially inhibit production of the bacterial cells in a medium containing a source of nitrogen and a source of carbon. Ethanol is then produced in the absence of substantial bacterial cell production by the addition of fermentable sugar to the bacterial cell suspension which is produced in the first stage. The preferred microorganism is a member of the genus Zymomonas.

Abstract: For the purpose of the electromagnetic detection of the speeds of moving parts, it is known to mount a coil (3) with a premagnetised soft iron core (2) as an electromagnetic displacement sensor in the vicinity of a tooth gear or of another moving member (1) which influences the magnetic return of the soft iron core (2). The object here is to specify a displacement sensor with which it is possible to detect the direction of rotation and which, moreover, yields unique signals for a wide range of speeds. The object is achieved in essence by the arrangement of a plurality of oppositely poled permanent magnets (4, 5), which are arranged between the moving member (1) and the soft iron core (2). It is possible in this case for the rotational speed and/or speed of moving members provided with ferromagnetic parts to be reliably detected over a wide range by counting zero crossings of the induced voltage (US). <IMAGE>

Abstract: A process for the solvent fractionation of palm oil stearine or of catalytically rearranged palm oil stearine, or other stearines from animal or vegetable sources into three fractions of widely different physical properties is described. One fraction is composed of high melting triglycerides (hard fat fraction), which melt from 45-65°C. A second fraction is composed of somewhat lower melting triglycerides which melt from 33-44°C (the confectionery fat fraction). The third fraction is composed of low melting triglycerides and is an oil at room temperature. The major value of these fractions is their ability to function as food components but they have numerous non-food uses particularly in cosmetics and pharmaceuticals. Their utility is not restricted to their individual use but on the contrary their usefulness may be tremendously increased by using them in combinations of two or more fractions or with other fatty materials.

Abstract: A carrier moving mechanism prevents backlash between a screw shaft (10) and a carrier (22) moved by this screw shaft. This carrier moving mechanism comprises a screw shaft and a carrier having secured thereon first and second nuts (26, 32) having teeth to be engaged with the thread (12) of the screw shaft. The teeth of the first nut are brought into contact with one side face of the lead of the screw shaft and the teeth of the second nut are brought into contact with the other side face of the thread (12) of the screw shaft (10) and the carrier (22) is moved through these first and second nuts (26, 32) by rotation of the screw shaft. The carrier moving mechanism also comprises a supporting mechanism (38) which supports one of the nuts (32) on the carrier so that the supported nut can be rotated in the rotational direction of the screw shaft (10) but the movement of the supported nut in the axial direction of the screw shaft (10) is restricted. Bias means (44) are provided for biassing the supported nut to rotate the supported nut in the direction eliminating the backlash and inhibiting means (50) are also provided for inhibiting the supported nut from rotating in the direction opposite to the direction of backlash-eliminating rotation, whereby the occurence of the blacklash due to wear of the teeth of the nuts and/or the thread of the screw shaft is prevented.

Abstract: A plastic corrugated sheathing hose adapted for electric cable installation and producible in one continuous operation, includes a longitudinal slit along its side. Each edge of the hose adjacent the slit is complementarily configured to form a detent or snap-locking closure releasably engageable in overlapping relationship. After insertion of a cable through the sheathing hose slit, closure of the hose is accomplished by pressing overlapped complementarily configured together. Closure of the hose in this manner results in a substantially gas-tight and waterproof cable enclosure accomplished in one operation with the inlaying of the cable.

Abstract: A temperature monitoring system, useful for example for detecting fires, comprises a cable (10) having at least two conductors (14, 16) separated by elongate temperature-sensitive means having reactance (C s ) and resistance (R s ), at least the resistance (Rs) varying with temperature. A voltage source (+V) sends a dc. current through a resistor (R) and said resistance (Rs), thereby to generate on a line (28) a d.c. signal that is representative of the value of the resistance (R s ). Switch means (22) is operative periodically to reverse the direction of current flow through the resistance (R s ), the frequency of operation being sufficiently low that, after the change in the signal that will take place upon each reversal due to the cable reactance (C s ), the signal will revert to a steady value before the next reversal. The steady state of the signal is sampled and held (30) and compared (32) with a reference value (fixed or variable). If the steady state value exceeds the reference value, an alarm or the like can be generated.

Abstract: @ A manipulation arm mechanism for an industrial robot is provided with a pivotable arm in which a first shaft driven by a drive motor is carried for rotation about an axis extending in a longitudinal direction of the arm. The first shaft has secured to its front end a rear casing, on which a front casing is carried for rotation about an oblique axis slanted relative to the first shaft axis. A head mounting shaft capable of attaching thereto a working head such as, for example, a handling gripper is carried in the front casing to be rotable about an axis which extends in axial alignment with the first shaft axis only when the front casing is at a predetermined angular position about the oblique axis. Second and third shafts driven by respective drive motors pass through the first shaft and present into the rear casing their front ends, to which the front casing and the head mounting shaft are drivingly connected through gear trains respectively. Each axis of the second and third shafts is radially offset from the first shaft axis. This offset arrangement ensures a relatively large space reserved just behind the front casing, so that the working range of the working head about the oblique shaft can be broadened.
