Abstract: A transducer having a cross field polarized permanent magnet mounted for slight pivotal movement within an annular coil winding. The magnet comprises neodymium-iron-boron to provide a compact, lightweight, low inertia and high intensity magnetic field. A magnetic field generated by current in the coil winding influences the permanent magnet to pivot slightly about a horizontal axis and rotate a yoke structure to produce a mechanical output of the transducer. In the preferred embodiment of the invention, the yoke is attached to a spring arm for controlling escape gas pressure from a nozzle to thereby control the pressure of a gas stream.

Abstract: In a distributed system, such as a PBX, which uses a database for its operation, a master copy (22) of the database having a first format is stored at a central node (10) and cache copies (32) of database portions (24) but having a different format are stored at peripheral nodes (11-12). A change to the database is made to the master copy, is recorded in a change table (26) corresponding to the affected database portion, and is sent to affected peripheral nodes. At initialization, a boot copy (25) is made of each database portion by translating the database portion from the master database format to the cache copy format. Periodically thereafter, each boot copy is replaced with a new boot copy that reflects changes presently recorded in the corresponding change table. When the new boot copy is generated, the present change table contents are erased. When a peripheral node calls for a new cache copy (e.g., upon reboot), it is sent the corresponding boot copy and any changes presently recorded in the corresponding change table.

Flexure of the flexible member (4,5,6) may be driven by electrostatic or piezoelectric forces. Alternatively, the flexible member may include a layer of piezoelectric material, the elongation or contraction of which will cause flexure.

Abstract: Die Erfindung betrifft eine Spannungsvervielfacherschaltung mit mehreren Stufen, wobei jede Stufe einen Pumpkondensator und mehrere MOS-Schalttransistoren aufweist. Mittels Taktsignalen werden die Schalttransistoren so gesteuert, daß die Ladung eines Pumpkondensators einer Stufe auf den Pumpkondensator der nachfolgenden Stufe übertragen wird. Der Betrieb einer solchen Schaltung mit Betriebsspannungen, die wesentlich geringer als 5 V sind, ist mit wesentlichen Nachteilen verbunden. Erfindungsgemäß wird daher jede Stufe einer solchen Spannungsvervielfacherschaltung mit einem zusätzlichen Transistor und einem zusätzlichen Korrekturkondensator ausgestattet. Hierdurch ist die erfindungsgemäße Schaltung mit einer Betriebsspannung von beispielsweise 2 V versorgbar.

It has a compact construction, high efficiency, high-energy output and pulses, mode and divergence stability and low variations in energy and output from pulse to pulse, it makes possible operation at high laser pulse repetition frequencies at extreme temperatures and it can be stored for years without replacing the Raman medium and optical components. This is achieved by a solid-state catalyst as catalytically active substance which contains a catalyst support made of  gamma -aluminium oxide,  eta -aluminium oxide or a mixture thereof; furthermore by the fact that this substance contains the noble metals platinum and palladium and also admixtures of antimony, manganese or tin, individually or in combination; and by the fact that this heterogeneous catalysis is combined with a homogeneous one, the solid-state catalyst being at least partly saturated with the homogeneous catalyst. <IMAGE>

Abstract: An apparatus for protecting the fault current intolerant elements of a motor starter circuit or the like is comprised of a protective shunt (14) which bypasses the fault current intolerant elements in response to the detection of high fault currents. The protective shunt (14) is formed of a "U" shaped conductor (26) which flexes in response to the magnetic field created by the flow of the high fault currents through the "U" shaped conductor. Electrical contacts (30, 32) placed on one leg (40) of the "U" shaped conductor (26) and on a stationary conductor (28) form a shunting switch which conducts high fault currents around the starter circuitry. In a second embodiment, the stationary conductor (28) is replaced with a flexible conductor which carries an armature. The magnetic armature is attracted by a focussed magnetic field from a magnetic yoke positioned around one leg (40) of the "U" shaped conductor (26).

Abstract: A pressure roller with an exchangeable pressure sleeve is mounted in a printing machine with a releasable mounting in such a way that, in order to change the pressure sleeve, it is held in the region of its one bearing pin protruding freely outwards in the machine frame. In order to permit a particularly simple exchange of the pressure sleeve, the bearings consist of hinged bearings (3) with bearing shells which can be folded away and permit the pressure roller (5) to swivel out in a horizontal plane after its release. One side of the pressure roller (5) is provided with a shaft pin (4) which is prolonged beyond the associated hinged bearing (3), on whose upper region a support shell (7) is supported, which shell can be rotated about a vertical axis in the machine frame but is mounted in an axially non-displaceable manner. A movable horizontal support rail (32) or guideway can be placed from below against, and fixed to, the pressure roller (5) or a shaft part (33), connected thereto, between the bearings (3) so that the pressure roller (5) held between the support shell (7) and the support rail (32) can be swivelled out of the opened hinged bearings (3) about the vertical swivel axis (8) of the support shell (7) (Fig. 1).
