Abstract: The invention relates to a method and a device for measuring visibility through a diffusing medium of variable opacity, for example fog. This method is characterised in that the back scattering is measured in the direction (7) included within the range of angles along which, for the wavelength ( lambda ) specific to the light which is emitted, there is a tendency towards coincidence of all the curves of variation of the phase functions as a function of the angle ( theta ) between the emission direction and the back scattering direction, each specific to a fog of particle size different from that of the other curves. This method permits the use of an ad hoc device to obtain a measurement of the visibility of the fog, which measurement is independent of the particle size of that fog. <IMAGE>

Abstract: In a position-measuring installation according to Figure 2, a ray bundle is diffracted at a first diffraction grating (202). The component ray bundles (- phi ,  theta . and + phi ) impinge on a second diffraction grating (203) which is tuned with a triple prism (206) in such a way that the component ray bundles (- phi ,  theta . and + phi ) intersect at a single point and emerge once again. On subsequently passing through the diffraction gratings (203 and 202), the component rays are in each case diffracted once again and then interfere. The interfering component ray bundles impinge on a detector device (207) by which they are converted into mutually phase-shifted measuring signals. <IMAGE>

Abstract: A technique for use in a public key exchange cryptographic system, in which two user devices estab­lish a common session key by exchanging information over an insecure communication channel, and in which each user can authenticate the identity of the other, without the need for a key distribution center. Each device has a previously stored unique random number Xi, and a previously stored composite quantity that is formed by transforming Xi to Yi using a transformation of which the inverse in computationally infeasible; then concatenating Yi with a publicly known device identifier, and digitally signing the quantity. Before a communication session is established, two user devices exchange their signed composite quantities, transform them to unsigned form, and authenticate the identity of the other user. Then each device generates the same session key by transforming the received Y value with its own X value. For further security, each device also generates another random number X′i, which is transformed to a corresponding number Y′i. These Y′i values are also exchanged, and the session key is generated in each device, using a transformation that involves the device's own Xi and X′i numbers and the Yi and Y′i numbers received from the other device.

Abstract: A liquid sterilizing system  (A)  defines a basin  (10)  in which a container  (B)  is removably disposed. The liquid sterilizing system selectively pumps sterile rinse liquids from a supply  (24)  and liquid sterilant solutions from a supply  (70)  into the basin filling the basin and the container. The container includes a lower shell having a bottom wall  (34)  that defines an aperture  (32)  for receiving sterilant and sterile rinse liquids. A nozzle plate  (44)  is mounted close to but spaced from the shell bottom wall to define a tortuous liquid distribution path  (40)  between the inlet aperture and nozzle plate apertures  (90) . A barrier  (96)  divides the liquid receiving portion and a drain portion of the liquid distribution path between the shell bottom surface and the nozzle plate. A cover  (80)  has a downward depending peripheral wall  (82)  which is offset from the shell peripheral wall  (86)  by the spacers  (88)  to define a tortuous vent path  (48)  therethrough. The container is lifted out by handles  (100)  which enable the container to be removed without disturbing the transparent cover, hence, without disturbing the sterile condition of the items within the container. In this manner, the sterilized items can be inventoried and maintained sterilized in the container for an extended duration.

Abstract: This invention relates to a dynamically shared facility network (DSFN) providing private network service to a plurality of customers using switched facilities of a common carrier network. A plurality of serving offices (2,4,6,8,10,12',64) are connected via access links to customer telecommunications equipment (1). A pool of channels is dedicated to providing communications for private network service among these serving offices. In response to a request from a customer, connections are set up in the serving offices between access links and members of the pool of channels, in order to interconnect the serving links sought to be connected by the request. Where tandem connections between serving offices are necessary, connections are set up between members of the pool of channels. In case of failure of one or more channels, a new connection is automatically established. Advantageously, communication channels of the large communications facilities of a public switched network can be allocated to the DSFN, thus achieving economies of scale, and thus permitting use of the large and flexible switching systems of the public switched network to control and switch channels of the DSFN.

Abstract: A tool fracture in automatic turning machines has devastating consequences if this is not detected in good time. For this reason, a great number of monitoring devices have already been proposed in which the tool in use in each case is checked for damage during the operating cycle sequence. According to the invention, a sensing needle (15) is provided which is guided radially to the centre axis of the tool (drill 5) and with regard to its guide (swivel arm 12) is flexibly mounted in a housing (14). When a tool (drill 5) is present, the sensing needle (15) (sensing stroke h') coming down onto the tool actuates the contact bank (17) of a magnetic switch (reed switch 16/17). The scanning stroke (h) of the swivel arm (12) is mechanically coupled via a tie rod (20) to the return movement of the tool (drill 5) into the rest position. A signal pulse is produced in the scanning time by a second magnetic sensor (24/25), which signal pulse initiates testing of the potential prevailing at the switch line (18) by a monitoring circuit (27). <IMAGE>
