IPC: C12N9/20
Filed: 1988-12-21
Abstract: In the preparation of fatty acid esters, reactants providing fatty acid and alcohol residues are reacted to produce said fatty acid esters in the presence of a lipase enzyme acting as catalyst. This reaction is conducted in a substantially non-­aqueous homogeneous liquid phase, the lipase being physically attached by adsorption to a hydrophobic porous solid support material of average pore size not less than 50 nm. The support is preferably a highly porous polymer, e.g. vinyl-based.

Abstract: A beating device (10, 11, 12), which can be triggered electrically, is provided to acknowledge key operations on electronic keyboards (1). The device is triggered by the occurrence of a key signal. Since the device is mechanically connected to the key region, the pulse produced in this way is transmitted to the keys (2) and is sensed there by touch. In this way, a mechanical stop is simulated in a simple manner which can, however, be triggered only when a detectable electrical key signal is produced. <IMAGE>

Abstract: A so-called H2 filament lamp is inserted into the socket and secured by means of a wire spring. The wire spring is bent in a Z shape viewed perpendicularly to the plane of the base contacts. The central web of the Z shape rests with pretensioning between the base contacts against the filament lamp and extends in the direction of the filament lamp central axis at an acute angle, opening towards the base plate, with respect to the plane of the base contacts. In the non-tensioned state of the wire spring, the web is at a larger acute angle with respect to the plane of the base contacts than when the wire spring is hooked in. In such a socket, the pressure force of the wire spring against the filament lamp is very large without the wire spring having to be hooked in with a very large exertion force. However, when the filament lamp is incorrectly inserted, the force which is necessary to hook in the wire spring increases noticeably. <IMAGE>

Abstract: A pipetting apparatus consists of a housing with a handle (1) and a pipette holder (17) for a pipette (19). A suction device serves for drawing a liquid into the pipette (19). A further device, by means of which the reduced pressure on the apparatus side is brought back to atmospheric pressure, serves for discharging a liquid drawn in from the pipette. To improve such a pipetting apparatus, a piston (6) provided with a press button (8a) for discharging a liquid is guided for longitudinal movement in the handle (1). The piston (6) passes through a sealing ring integral with the housing. On the side of the press button (8a) away from the sealing ring, an outflow space (43) connected to the pipette holder (17) is provided in the housing (1, 2). At its end away from the press button (8a), the piston (6) has a first region corresponding to the diameter of the sealing ring and an adjoining second region in which the diameter decreases in the direction of the press button (8a) (Figure 1). <IMAGE>

Abstract: A magnetic resonance imaging system is adapted to achieve the imaging of magnetic resonance signals detected from an object by applying a high frequency magnetic field and gradient field to the object in a homogeneous static field in accordance with a predetermined pattern and includes a data pick-up section (101-104, 107-111) and image processing section (112). The data pick-up section (101-104, 107-111) is of such a type that, with the use of a predetermined pulse sequence so time-adjusted that a phase difference between two predetermined substances somewhat differing in their magnetic resonance frequency due to a chemical shift is π/2 or -π/2 on a predetermined time, picks up all magnetic resonance data necessary for reconstruction of an image of a slice excited by the high frequency field into magnetic resonance within a period of time in which that predetermined nuclear magnetization of the slice is relaxed due to the relaxation of a transverse magnetization The image processing section (112) obtains a magnetic resonance image of at least one of the two substances gained, in a manner separated into real and imaginary part of image information, by subjecting magnetic resonance data picked up by the data pick-up section (101-104, 107-111) to a two-dimension complex Fourier transformation. It is thus possible to obtain a magnetic resonance image of at least one of the two substances in a very small period of time.

Abstract: A linear transducer has an electrically conducting rod 5, mechanically connected to respond to the movement to be detected, which slides within an electrical winding 8 mounted on an insulating former 6. The winding 8 is connected as part of an LC circuit for an oscillator 24. As the rod 5 moves inwardly of the winding 8, eddy currents are induced in it by the energised winding 8 and reduce the inductive component of the electrical impedance of the winding. The resultant change in oscillator frequency is a measure of the movement to be detected. The transducer has an external metal casing 14. In order to prevent such eddy currents being induced in the casing 14 as to mask the effect of changes in eddy currents induced in the rod 5, the casing 14 is provided with means, such as an axially directed slit, which significantly increases the impedance of the eddy current paths within it. The slit may be sealed off by suitable electrically insulating material, so as to enable the interior of the transducer to be pressurised if a particular application requires this.

Abstract: A memory (80, 82) which contains a global data line pair (80, 82) and a plurality of loads (90, 100, 110) for the global data line pair (80, 82) distributed thereon. The global data lines (80, 82) run the length of the memory (80, 82), and are connected to a set of arrays (36, 38) distributed along the global data lines, of which each array provides a voltage on the global data lines (80, 82) when selected. The first load (90) is located above the first array (36) and the last is located below the last array (38). Other global data line loads (100) are placed between consecutive arrays (36, 38). In a read mode of operation a pair of loads associated with each array is enabled when a corresponding array is selected. Placement of the loads in this manner decreases an access time considerably.

Abstract: The charge transfer efficiency of a two-phase charge-coupled device cell is enhanced by providing a three-tiered built-in potential in the channel of each cell. Two lower potential tiers form a trenched potential well in the cell for storing charge. A higher potential tier between the trenched potential well of a cell and the potential well of a preceding neighbor cell provides a poten­tial barrier preventing backflow of charge from well-to-well. The potential trench is located at the downstream end of the well adjacent a succeeding neighbor cell of the CCD.

Abstract: An equipment rack is disclosed whose frame member arms include protrusions, or a protrusion and a flange, that serve a dual function. First, the protrusions, or protrusion and flange, serve to define channels suitable for receiving a cable restraint device which serves to separately bundle cables according to type and/or function. Second, the protrusions serve as keyways along which additional, movable frame members slide telescopically to achieve a rack extendible to a wide variety of heights. Preferably, the inventive rack is of aluminum, resulting in a rack that is essentially as sturdy as the conventional steel racks but significantly lighter and easier to install.

Abstract: A sootblower wallbox assembly for decreasing noise emissions during the cleaning of a heat exchanger apparatus. In particular, the invention relates to a wallbox assembly containing a number of reverberant chambers exhibiting varying attenuation characteristics. When a cleaning lance is extended centrally through the wallbox assembly, a baffle portion of each chamber is in close fit relation with the exterior surface of the lance. Each reverberant chamber has a different axial length and therefore exhibits a different frequency range where it achieves its best sound attenuation. The wallbox assembly can also be provided with control systems to prevent combustion products from escaping the heat exchanger through the assembly.
