Title: Pressure supply unit.
Inventor: LESLIE MICHAEL JOHN
IPC: F17C7/00
Filed: 1989-04-07
Abstract: A pressure supply unit to supply pressure to a dispensing can, the unit being attached to a gas bulb containing gas under a predetermined pressure. The unit has a chamber pressurized to the desired can pressure, and one wall of the chamber is a diaphragm connected to a needle valve for regulating gas flow from the bulb. A reduction of can pressure causes the diaphragm to move the needle to release gas from the bulb.

Abstract: On a mis au point un sélecteur (34) et un régulateur (24) d'écoulement utilisé dans un agencement de gestion intraveineuse, capable d'établir la vitesse d'écoulement sans étalonnage au moment d'utilisation, puis de maintenir automatiquemenet cette vitesse d'écoulement quels que soient les changements de la pression de fluide an amont et/ou en aval du régulateur. Ledit régulateur (24) utilise un diaphragme (32) insensible à l'étirement ou au travail des matières avant l'utilisation, pour réguler un orifice. On peut étalonner ledit régulateur lors de la fabrication directement en termes de débit. Ledit diaphragme (32) est serré au niveau du rebord et comprend un tore arqué (82) faisant face à l'admission (42), ainsi qu'une section centrale (84) à bulbe, régulant l'écoulement à travers un orifice de sortie. Du liquide contourne le diaphragme (32) par le rebord. D'autres modes de réalisation incorporent ledit régulateur dans une chambre d'égouttement (150) et réduisent le nombre de pièces dudit régulateur à trois éléments pouvant s'encliqueter.

Abstract: An apparatus for beheading fish comprises a supporting plate 10, a cover plate 12, and a fluid bag 13 with a fluid inlet 14. The apparatus is open at both ends, and the fish is placed with the head free. Fluid under pressure is thereafter introduced through the inlet 14 into the fluid bag 13 which is thereby inflated to the shape as shown. As the bag is resilient, but is confined between the fish and the supporting plate 10 and the cover plate 12, respectively, the fish will thereby be seized between the bag and the supporting plate. An extremely effective and firm mechanical seizure of the fish is thereby achieved, even under moist, slimy or slippery conditions likely to prevail where fish are be­ing processed. When the fish is seized by an appropriate pressure in the fluid bag 13, it is held so firmly that the head can be torn off. This is performed by means of the tool seen to the right in the figure and which comprises a plane abutment plate 16 which is pushed in below the front edge of the supporting plate 10, a pivotal gripping jaw 15, being shown in the figure in its free position above the fish approximately a­breast of the gill cover 4. If also the ear bone of the fish is removed, the roe can be removed from the fish by increasing the fluid pressure in the bag, so that the roe is squeezed out. 
     The invention also comprises methods for beheading fish and for ex­traction of roe or milt from a fish.

Abstract: The composite ultrasound transducer comprises transducer elements (12) which are made of piezoelectric ceramic, radiate essentially in the longitudinal direction and are embedded in a plastic matrix (11). The geometrical structure of the transducer elements (12) and their arrangement with respect to one another is such that any generation of vibration modes perpendicular to the longitudinal direction of the transducer elements (12) in the composite ultrasound transducer is suppressed. The composite ultrasound transducer is produced by a slip casting process using a plastic mould which quantitatively burns without leaving solid residues when the ceramic is fired. In the fabrication process, a plastic mould, in particular, is used which produces any desired structures, in particular hexagonal or irregularly square structures having a trapezoidal cross section parallel to the longitudinal direction, and arrangements of the transducer elements.

Abstract: 2. The invention is based on the object of disclosing an electric cigar lighter with an overload protection device which no longer switches on automatically after being switched off by an overload. 
<??>3. This object is achieved by the use of a bimetal snap-action disc (7) in the overload protection device (4) which, when a switch-off temperature is exceeded, changes suddenly from one shape (I) into a second stable shape (II) and retains this shape (II) even after cooling down. The overload protection device (4) has to be mechanically reset. This resetting can take place according to advantageous embodiments even without using a tool.

Abstract: With an interpolation circuit (1) according to Figure 1, an instantaneous vector (21) is formed for subdivision of measurement signals (sin, cos) which are phase-shifted in relation to one another. With the aid of a vector generator (2), a reference vector (20) is generated which is approximated in stages to the instantaneous vector (21). Analog values of both vectors (20, 21) are compared in comparators (6, 7) and a control logic (3) controls the vector generator (2) depending on the result of the comparison. If the approximation of the comparison vector (20) to the instantaneous vector (21) is adequate, this successive approximation is interrupted and the intermediate value is output according to angle and amplitude via output lines (15 and 16). <IMAGE>
