Abstract: A B S T R A C T     A fused salt reduction cell for producing aluminum com-prises a cathode pot having an outer steel shell (10) sup-ported on or by metal structural parts, a thermally insul-ating layer (12,14) and an inner lining (16,22) which is of carbon, is electrically conductive and is resistant to attack by the molten aluminum and the electrolyte.     In the region of the electrolyte there is a layer which runs horizontally around the cell dividing the carbon lin-ing into a lower part (16) and an upper part (22). This layer (22) is of a material which is resistant to the el-ectrolyte at temperatures up to 1000°C and has a much lower shear strength than that of the carbon lining.     (Fig. 2)

Abstract: ABSTRACT          A modular unit 10 for constructing structural supports comprises an elongate member 12 and a link 14 extending laterally from the member. Castellations 28 are provided around a rim 26 at either end of the member so that the elongate members of similar units can be mated together.   The link is made up of two struts 16 and 18 which are offset to one side of the elongate member and a flange 20 with bolt holes 22 is provided at the end of the link.   Thus the links of two similar units can be bolted end to end to form a basic unit for use in constructing structural supports.   Such a basic unit has two elongate members which are substantially parallel to each other and held apart and connected by the links.   The invention also extends to an integral basic unit having such a configuration.

Abstract: Title:    HYBRID CAMERA ARRANGEMENT                 ABSTRACT OF THE DISCLOSURE         A "hybrid" exposure control system for a photographic camera apparatus controls exposure in response to both the firing of a quench strobe at an appropriate size aperture corresponding to the determined camera-to-subject distance and to the subsequent quenching of the strobe in response to the detection and integration of reflected strobe light from the scene in correspondence with the scene light admitted to the film plane.  An increased degree of exposure correction can thus be made possible since a slight error in determining the camera-to-subject range can be compensated by the detection and integration of reflected strobe light to provide a flash quenching signal.

Title: Multidiameter cavity for reduced mode competition in  gyrotron oscillator
Inventor: EVANS STEVEN J
IPC: H01J25/00
Filed: 1983-12-05
Granted: 1987-01-20
Abstract: Abstract Multidiameter Cavity for Reduced Mode Competition in Gyrotron Oscillator In a gyro-monotron oscillator a single, "monotron" cavity is used to interact with the electron beam.  To handle very high powers without excessive cavity loss, the cavity is excited in a higher order mode such as TE0ml.  Other modes can be resonant in the cavity, interfering with the operation when their frequency is near the operating frequency.    To increase the mode separation, an upstream section of the cavity is made smaller, to support only a lower-order mode such as TE011.  Also, the beam is pre-bunched by this lower order, interference-free mode so has less tendency to interact with spurious modes in the higher order cavity.

Abstract: ABSTRACT OF THE DISCLOSURE            There is provided a system for controlling the rotation of a propeller unit of a Z-type propulsion apparatus in which the propeller unit does not rotate in the direction opposite to that of rotation of a steering handle even when the steering handle for commanding the propeller unit to rotate is angularly moved by more than +180°.  A vector calculation circuit either produces a sinusoidal signal representative of a sine of the difference of angle between the steering angle of the steering handle and the follow-up angle of the propeller unit and a cosine signal representative of a cosine of the difference of angle or produces the sinusoidal and cosine signals and a second sinusoidal signal representative of an angle obtained by adding 45° to the difference of angle.  And a signal processing circuit produces, in accordance with either the first and second sinusoidal signals and cosine signal or the first sinusoidal and cosine signals, a signal whose polarity is not reversed even when the steering angle exceeds +180°.  The signal produced by the signal processing circuit is supplied to a drive unit for rotating the propeller unit to thereby control the rotation of the propeller unit.

Abstract: La présente invention concerne un ohmmètre pour mesurer des très faibles résistances électriques, par exemple la très faible résistance d'un raccord électrique à très fort courant. Une source est prévue pour établir un courant de mesure à travers le raccord pour ainsi créer une chute de tension proportionnelle à l'intensité du courant de mesure et à la résistance à mesurer. Un premier intégrateur intègre un signal représentatif de l'intensité du courant de mesure afin de produire un premier signal d'intégration, tandis qu'un second intégrateur intègre la chute de tension proportionnelle au courant de mesure et à la très faible résistance pour ainsi produire un second signal d'intégration. Les deux intégrateurs sont remis à zéro simultanément de sorte qu'ils amorcent leurs intégrations en un même instant. Le premier signal d'intégration est comparé à un signal de référence à l'aide d'un comparateur. Lorsque l'amplitude du premier signal d'intégration atteint l'amplitude du signal de référence, le comparateur émet un signal qui interrompt l'intégration effectuée par le second intégrateur. Le second signal d'intégration est alors mémorisé, celui-ci ayant une amplitude qui constitue une mesure de la très faible résistance électrique. Un dispositif d'affichage reçoit le signal d'intégration mémorisé pour afficher la valeur de la résistance mesurée.

Abstract: Abstract of the Disclosure A braking arrangement or a motor-driven chain saw is disclosed.  The braking arrangement is actuable by a releasing device and is held in the release position against a spring force by means of a latching device.  The braking arrangement includes a brake band holding member to which a brake band is fastened.  The brake band can be tightened around a clutch drum of the motor-driven chain saw by means of an ancillary chain brake device provided in addition to the chain brake device, so that the clutch drum is brought to an immediate stop.  This braking action occurs also if the releasing device of the chain brake device is not actuated.  In this way, the chain brake device remains activated thereby enabling it to act during operation of the chain saw, for example, in the event that the motor-driven chain saw kicks back while the saw chain is running.  The ancillary chain brake device is preferably operable by the throttle lever or the throttle lever locking device so that the clutch drum is braked on throttling back.  In this way, a continued running of the saw chain after release of the throttle is thereby reliably prevented.

Abstract: ABSTRACT This invention relates to an electronic detector which in combination with other sensing means e.g. for weight, di-mension and deformation force, provides a reliable safety that a refund is only paid for approved aluminium cans and that the collected and compressed aluminium scrap is not contaminated by another material. The electronic sensing is baaed on an electrically self-oscillating circuit containing a coil (3) placed around or at least partly enclosing the object (2) placed in the deposit apparatus. As the object (2) to be de-tected damps the above-mentioned oscillations it is possible by means of a suitable tuning of the electronic system to de-termine which frequencies belong to accepted aluminium cans. Thus, certain ranges of frequency correspond to accepted cans while ranges lying outside are considered as not accepted. By means of a microprocessor these approved or not approved ranges can be easily sorted out. The above-mentioned electro-nics adapted to this sorting system in return apparatuses for aluminium cans give a reliable safety as far as sorting out faulty or not accepted material is concerned.
