Abstract: 13 ENVELOPPE PERIPHERIQUE POUR UNE MUNITION GUIDEE TIREE PAR EFFET CANON L'invention concerne une munition guidée, tirée d'un système de lancement par effet canon. Cette munition (1) comportant des sous-ensembles est soutenue, lors de la mise en vitesse dans le canon, par une enveloppe (2) périphérique reposant sur le premier sous-ensemble (3) de la munition (1) placé à l'avant de la munition et solidaire d'un sous-ensemble éjectable (9) placé à l'arrière de la munition. La masse de cette enveloppe est nécessaire pour supporter les efforts dus à l'accélération et elle permet d'augmenter la portée de la munition pendant la phase balistique Lors du passage de la phase balistique à la phase guidée, le sous-ensemble éjectable (9) est éjecté entraînant avec lul l'enveloppe (2) qui libère ainsi les surfaces portantes déployables (6 et 7). L'enveloppe ainsi positionnée assure également une étanchéité, une protection des parties sensibles et une rigidité de l'ensemble de la munition.

Title: Method of preventing mis-emission of a laser beam in a laser robot
Inventor: TORII NOBUTOSHI
IPC: B23K26/08
Filed: 1990-05-28
Abstract: A B S T R A C T A laser-beam mis-emission preventing method capable of improving safety of a laser robot.  Upon supply of power to the laser- robot. a processor of a robot control unit (10) compares a predetermined value with an angle (.delta.) formed between a horizontal plane (XY plane) and an axis (8a) of a laser nozzle (8) and computed based on joint angles (W, U, r, .beta.) (S1 - S3). When the laser nozzle angle (.delta.) is less than the predetermined value, an interlock signal delivered to the laser oscillator (30) is set to turn off the power of the laser oscillator, thereby bringing the laser oscillator into a condition incapable of laser oscillation (S5).  This prevents mis-emission of the laser beam which occurs due to deficiency of a robot operating program, erroneous manual operation, etc., and which can damage the human body or peripheral devices.

Title: Torque responsive brake
Inventor: FAHY ARTHUR J
IPC: F16D63/00
Filed: 1991-05-03
Abstract: ABSTRACT            (See Figure 4) The mechanism 204 prevents reversal of the torque of shaft 203 by braking two disc members 206, 207 against braking surfaces of a casing 205. Under normal operating conditions the member 206 is turned by a motor 202 controlling a load 200 in a direction which causes its drive to be transmitted through balls 221 to the member 207. In this condition minimal braking occurs. If the direction of the shaft 203 is reversed, the balls 221 force apartcontiguous camming surfaces on the disc members so that their braking surfaces engage the casing to brake the shaft 293. Controlled manual release of the load under braked conditions is permitted by turning a handle 224 driving a shaft 210 which turns the member 207. Minimal braking friction during normal operations is reduced still further by creating a cushion of oil between the braking surfaces, the oil being provided by a gear pump 216 driven off the shaft 210. The braking surfaces on the casing are referenced 208, 209 and are borne upon by complementary rim surfaces of the disc members 206,207.

Abstract: An apparatus far determining the fundamental viscoelastic properties of a viscoelastic material includes means for imparting a torsional stress in a viscoelastic material; means for measuring the relaxation of the torsional stress over time and converting the relaxation stress to a representative waveform; and processing means for determining the frequency dependant fundamental viscoelastic properties of the material based on the shape of a portion of the waveform. Preferably, the processing means includes a first dedicated processor for producing a digital representation of the waveform and a second general processor, such as an IBM compatible microcomputer for determining the fundamental viscoelastic properties from a portion of the digital representation. To facilitate automating the determination of the fundamental viscoelastic properties of the test material, the first processor examines the waveform and aborts the determination if the digital waveform is atypical of an expected waveform for a viscoelastic material subjected to a torsional stress. A method of determining the fundamental viscoelastic properties of a viscoelastic material includes the steps of imparting a torsional stress in a viscoelastic material;  measuring the relaxation of the torsional stress over time and converting the relaxation stress to a representative analog waveform; digitizing the representative analog waveform to produce a representative digital waveform; and, determining the frequency dependant fundamental viscoelastic properties of the material based on the shape of a portion of the representative digital waveform. To facilitate automating the method, the shape of the waveform may be analyzed to detect the start of a test, the end of the test, and whether the test is a valid test. Preferably, the fundamental viscoelastic properties of the test material are determined by converting the torque based amplitudes of the waveform to shear relaxation modulus values, such as by multiplying the torque amplitudes by the geometric form factor of the test material, and then by transforming the shear stress modulus values to frequency dependant fundamental viscoelastic properties through the known Yagii/Maekawa approximation.

Title: Method and apparatus for preventing local bunching of cars in an elevator group with variable traffic flow
Inventor: MACDONALD ROBERT
IPC: B66B1/20
Filed: 1992-03-11
Abstract: A method of minimizing car bunching at any traffic flow level allocates closely adjacent stops to a given car which is favored by a variable, readjustable distributor bonus. The estimated lost time costs of all passengers are computed for each elevator and for each hall call, these costs are reduced by a variable distributor bonus concentrating adjacent stops in one car, and a hall call is then allocated for service to that elevator which displays the lowest, reduced estimated lost time costs.      In order to assure the function of this method equally at high and low traffic levels, the variable distributer bonus (Bvn) is readjusted to the traffic flow level (Va) which serves as a tracking parameter by means of a tracking function according to the relationship Bvn =      Bv.cndot.F(Va) and the readjusted variable distributor bonus is defined thereby. The tracking function F(Va) is determined by one of artificial intelligence methods and expert programs. By the dependence of the distributor bonus on traffic flow, the desired small local bunching of elevator cars is an optimum for every traffic level. This method is applicable to a plurality of different allocation criteria, service requests and tracking parameters.
