Abstract: The syringe is comprised of an external cylindrical body (1) and a suction and ejection piston (2) displaceable within said body, the piston including at its internal end the corresponding seal (3). According to the invention, said seal is held at the extremity of the piston by means of one or a plurality of arms (4) hinged at said end of the piston, said arm or arms traversing the side wall of the seal to retain the latter. The arms have a sharpened free end (6) and a cutting front edge (7), so that, during the advance movement of the piston during the ejection phase, the wall of the external cylindrical body is cut, no cut being done during the suction displacement. The syringe is disposable and not reusable after its first and single use.

IPC: A23G1/18
Filed: 1992-07-16
Abstract: The process and apparatus for continuous, controlled crystallisation of material systems, in particular fat-containing masses such as chocolate mass, operate by a thermal treatment including cooling and heating. The cooling is carried out much more intensively than in the conventional procedure and intensively enough so that the material system to be treated would solidify spontaneously in the stationary state. This solidification is prevented by heating by mechanical energy dissipated during shear stress, that is in a shear flow, the mechanical energy input and thus the local temperature being spontaneously and sensitively controllable. As a result, predeterminable crystal modifications and thus desired properties of the end product are achieved. The treatment preferably takes place in an apparatus composed of a cylindrical vessel (4) and a rotary driven rotor (21) whose speed of rotation is controllable. Between the cooling jacket and rotor is formed a shear gap, in which the mechanical energy for the generation of heat is transferred to the material system to be treated. The energy transfer is controllable virtually without time delay. The crystallisation times are greatly reduced, as a result of which the overall apparatus becomes smaller and cheaper. Only one tempering (or temperature) zone is required. The product leaves the apparatus at processing temperatures having defined viscosity.

Abstract: This device contains in a transmitting/receiving unit (1), in addition to the usual transmitter (3) and receiver (4) with associated detection circuit (10), a second receiver (5) which can be reached directly by the radiation emitted by the transmitter (3) and which is associated with a second detection circuit (12). In an initialisation mode in front of a stationary reflector, the operating voltage of the transmitter (3) or the gain of the detection circuits (10, 12) is continuously increased by a control unit (9) until the desired sensitivity is reached. The values of representative voltages at which the two detection circuits (10, 12) trigger are stored in two memories (13, 14). The quotient of these two values is stored in a third memory (16). In an adjustment mode which is carried out at particular time intervals, the control unit (9) also continuously increases the operating voltage of the transmitter (3) or the gain of the detection circuits (10, 12) and determines the value of the representative voltage at which the second detection circuit (12) outputs an output signal. This value is supplied, together with the quotient stored in the third memory (16), to a multiplier (17). The output signal of the latter is representative of a nominal operating voltage of the transmitter (3) or gain of the detection circuits (10, 12), the adjustment of which is finally handled by the microprocessor (9).

Abstract: An ultra-quick charging device for charging battery packs having a wide range of output voltages. The charging device includes an AC to DC high current power supply circuit and a microcomputer-based controller circuit for monitoring the voltage of the battery and converting from fast charge to trickle charge when the second inflection point in the battery voltage charge curve is detected. In order to permit the device to charge battery packs of different rated voltages, the device includes a logarithmic analog-to-digital converter circuit having a selectable prescaler circuit that attenuates the battery voltage signal. The microcomputer is programmed to automatically set the appropriate attenuation level of the prescaler circuit at the outset of the charging cycle by assuming that the maximum voltage of the battery pack being charged will be less than or equal to 150 percent of its observed battery voltage. The present invention is able to automatically fully charge battery packs ranging in voltage between 3 volts and 24 volts.

Abstract: The reheat tub (T) in a double-flow steam turbine is provided with additional setback from the rotor buckets (38) by forming a three-part reheat tub construction including first and second discrete diaphragm segments (26,28) and third inner ring segments (36). The annular arrays of these segments are dimensioned to enable greater axial spacing between the nozzles (34) and buckets (38). To refurbish an in-service double-flow turbine, the damaged reheat tub is removed and cut along axial and radial part lines to form discrete first and second diaphragm segments. The diaphragm segment nozzles are then refurbished by adding weld material and machined to the appropriate configuration. Material is added to the downstream and removed from the upstream faces of each diaphragm so that it may be located in the turbine shell similarly as the removed tub, but with the nozzles spaced further axially upstream of the buckets.

Abstract: The invention relates to the high-voltage changeover switches which are used to apply the high voltage to two X-ray tubes alternately. 
<??>The invention lies in the fact that each of the four interrupters constituting a changeover switch comprises a fixed stud (f) connected to an input terminal of the high voltage and a moving stud (m) connected to an output terminal by a curved flexible blade (52), the displacement of which is obtained by a hinged arm (55) which is actuated by an insulating sleeve (41) surrounding the blade (52). The rotation of the sleeve (41) in one direction brings about contact through an orifice (58) in the wall of the sleeve (41) whereas rotation in the reverse direction brings about the separation of the contacts and the interposition of the insulating wall between the parted contacts. 
<??>The invention is applicable to radiology installations.
