Title: Extremely sensitive metallic vapor detection
IPC: G21H5/02
Filed: 1976-07-02
Abstract: An extremely sensitive metallic vapor detection method primarily for use in a sodium cooled nuclear reactor containment. Sodium vapor, or a compound derived from it, is allowed to react with a radioactively tagged substance so as to produce a radioactive gas. The released gas is monitored by a nuclear counter, which provides a direct indication of the presence of metallic vapor. The method is sensitive to the presence of metallic vapor in a gaseous environment in the range of 10-16 grams per cubic centimeter.

Title: A new delayed action electrical protection device, depending on an adjusted magnitude.
IPC: H02H3/07
Filed: 1978-04-13
Abstract: This invention provides a delayed action electrical protection device which may be used for example to protect electrical lines and equipment against disturbances such as overload conditions and minimum voltage conditions. An analogue signal denoting the particular condition for which protection is to be provided is converted into a digital signal which is applied to a micro-processor. In the micro-processor this digital is compared with a prescribed value or values fed into the processor. The processor contains information relating to characteristic curves which define the time delay between the detection of a particular condition and the production of a tripping signal which may, for example, be used to interrupt the electrical circuit and/or provide an alarm. The time delay varies inversely with the magnitude of any disturbance and may, for example, be defined by the expression:- @@@@ where K is a constant i equals I/I@ where I is the measured current and In is the prescribed value.

Title: Printing apparatus.
IPC: B41J2/525
Filed: 1979-07-27
Abstract: Printing apparatus, in particular for performing multi-color printing operations, has a ribbon shift mechanism for selectively interposing different transversely spaced portions of a print ribbon between a print head and platen. The print head is of the impact type and probably, although not necessarily, of the type which moves along the platen to define a print row. When color printing is required, a ribbon having a plurality of longitudinally extending stripes of different colors transversely spaced across its width is used. Selection of required portions or colors of the ribbon is performed by moving the head to pre-selected positions along the print row to engage, for example, a camming mechanism (including a cam and follower) which moves the shift mechanism the required amount to make the selection. Selection of the ribbon portion or color is by program control and in the case of color printing, the range of colors is increased by superimposed printing of the available colors on the print ribbon.

Abstract: An arrangement for receiving or reproducing sound waves, comprises five, seven or nine transducers situated in line at equal distances from each other (such as for example 1 to 5), all transducers each being connected to the same transmission channel via an individual amplitude control device (11 to 15). The amplitude control devices are adjusted so that the ratios between the conversion factors of the combinations of a transducer and an associated amplitude control device, viewed from the one end of the arrangement to the other end, are 1 : 2n : 2n<2>: -2n: 1 in the case of five transducers, 1 : 2n : 2n<2> : n<3> - n : -2n<2> : 2n : -1 in the case of seven transducers, and 1 : 2n : 2n<2>: n<3>- n: 1/4(n<4> - 1) - 2n<2>: -(n<3>-n) : 2n<2>: -2n: 1 in the case of nine transducers. This results in an output signal of the arrangement which is substantially independent of direction and/or frequency. Moreover, the arrangement may be realized in a very simple manner. The invention also relates to a combination of five, seven or nine arrangements as described in the foregoing (for example 41 to 45), which are situated adjacent each other or in line at equal distances from each other. The arrangements each comprise a further amplitude control device, which devices are all connected to a transmission channel of the combination. The amplitude control devices are adjusted so that the ratios between the conversion factors of the arrangements viewed from the one end of the combination to the other end, are 1 : 2m : 2m<2> : -2m : 1 in the case of five arrangements, 1 : 2m : 2m<2>: m<3>-m : -2m<2> : 2m : -1 in the case of seven arrangements, and 1 : 2m : 2m<2> : m<3> -m: : 1/4(m<4>- 1)-2m<2> : -(m<3>- m) : 2m<2> : -2m: 1 in the case of nine arrangements.

Title: Process and device for the production of a telecentric light beam and use of the process
IPC: G01B11/02
Filed: 1982-06-03
Abstract: In a device for the production of a telecentric light beam which is to be deflected over a defined region an incident light beam impinges upon a rotating plane mirror. The light beam reflected thereby reaches the outlet of the device by way of a further co-rotating parallel plane mirror as a telecentric light beam. There is thus obtained by simple optical means a deflection over a region which is considerable in comparison with the dimensions of the device, and the shifting of the deflected light beam occurs according to a simple mathematical function, more especially a sine function. This simple mathematical relationship of a rotary angle and a displacement of the light beam enables an especially simple evaluation of measurement data.

Patent ES-8501052-A1 (ES)
Title: Centrifugal separator.
IPC: F01M1/10
Filed: 1983-01-18
Abstract: A centrifugal separator for separating contaminants from contaminated oil has an outer casing (10, 11) and a rotor (20) within that casing mounted for rotation about a vertical axis. Oil under pressure enters the rotor at one end and at the other end exits through jets (78) into a chamber within the casing which is normally filled with air. As the jets of oil impinge upon the inner wall of the casing, a small amount of air becomes entrained in the oil and as the oil flows to a sump, the air is gradually removed from the interior of the casing. In order to prevent a build-up of oil within the casing, which could interfere with rotation of the rotor (20), air under pressure is supplied to the interior of the casing by means of a float-operated valve member (113) so that while the valve member is normally closed, any increase in the oil level will cause the float (124) to rise with that oil level and thereby open the valve (113) to allow additional air to enter into the interior of the casing.
