Title: Saw devices with reflection-suppressing fingers
IPC: H03H9/02
Filed: 1986-02-21
Granted: 1991-11-27
Abstract: 57 Each IDT (inter-digital transducer) (12, 14) of a SAW (surface acoustic wave) device has a linearly tapered back edge formed by reflection-suppressing fingers (18, 26) of successively decreasing length spaced apart with a pitch of lambda/4 behind the active region (16, 24) of the IDT, where lambda is the wavelength of a SAW to be propagated, whereby [ SAW reflections at the back edge of the IDT are substantially eliminated. A thin resistive doped sili- r con film (40, 42) between the back edge of each IDT and the adjacent edge (36, 38) of the substrate absorbs waves propagated via this back edge. The film underlies the IDTs to provide improved adhesion to the substrate.

Patent EP-0214175-B1 (EP)
Title: Vertical magnetic recording arrangement
IPC: G11B5/02
Filed: 1986-01-22
Granted: 1993-05-12
Abstract: The present device provides a downstream magnetic shield which is integrally formed with a write pole section having a tip to make up a magnetic recording head. The shield and the write pole tip are located with small gap therebetween, so that magnetic flux which fringes from the magnetic write pole tip is intercepted by the shield. Accordingly such fringing flux does not pass through the recording medium, and hence if a data bit has been written into the recording medium its dipole identity will not be weakened by the fringing flux of a subsequent data bit being written into the magnetic recording medium. In addition, the magnetic recording medium is made up of a first layer of material having perpendicular uniaxial anisotropy and an underlying layer made of a material which has a low magnetic flux reluctance characteristic. Accordingly, the magnetic flux passes vertically through the first layer, along the second layer and finally passes vertically from the second layer through the first layer into the shield. The face of the shield is designed to be many times as large as the face of the write pole section so that the density of the flux from the tip is sufficient to effect a vertical recording while the density of the flux passing into the downstream magnetic shield is low and hence a previously recorded pattern is not reversed.

Abstract: Pressure infusion apparatuses are known in which the speed of rotation of a volumetric pump is regulated by determining, from the change in weight of the fluid container per unit of time, the conveyed volume current and comparing the latter with an intended value of infusion rate. Such systems are susceptible to the breakdown or the failure of individual components. In order to increase the reliability against failure, according to the invention a monitoring channel (15, 27, 28, 30) is provided in addition to the gravimetric measurement channel (10, 18, 20, 22), which monitoring channel produces a second measurement value (MW2) of the volume current by measurement of the drop count. The second measurement value (MW2) may deviate only by a predetermined amount from the intended value (SW) and it may also differ only by a predetermined amount from the first measurement value (MW1); otherwise, an alarm is triggered. <IMAGE>

Granted: 1990-01-17
Abstract: Apparatus for stacking conical objects (2a, 2b, 2c, 2d, 2e) includes right hand and left hand side walls (3) and (4) which are joined by divergent walls (7) to define a tapering horizontal cross-section column (l) in which the spacing between the opposite walls (3) and (4) is shorter than the length of any one of the conical objects (2a-2e). The conical objects can be placed manually in the top of the column (l) but only in a given orientation (thanks to the tapering horizontal cross-section of the column (l) and only when hooked on a retaining finger (5) projecting into the column through the side wall (4). The conical object (2e) at the top of the stack thus settles into an inclined orientation which it retains when the retaining means (5) is released to drop the cone (2e) down the column, thanks to an inertia brake (8) to retard the wider diameter end of the falling cone and preventing the cone from becoming vertical. Retaining means (l0) at the foot of the column releases only the bottom cone (2a) and allows any cones above it to become indexed downwardly into the bottom-most position.

Title: Speech-recognition circuitry employing phoneme estimation
IPC: G10L15/02
Filed: 1988-03-31
Granted: 1993-02-03
Abstract: A phoneme estimator (12) in a speech-recognition system (10) includes trigger circuitry (18, 22) for identifying the segments of speech that should be analyzed for phoneme content. Speech-element processors (24, 26, and 28) calculate the likelihoods that currently received speech contains individual phonemes, but they operate only when the trigger circuitry identifies such segments. The computation-intensive processing for determining phoneme likelihoods is thus performed on only a small subset of the received speech segments. The accuracy of the speech-element processors (24, 26, and 28) is enhanced because these processors operate by recognition of patterns not only in elements of the data-reduced representations of the received speech but also in higher-ordered products of those elements; that is, these circuits employ non-linear modeling for phoneme identification.

Abstract: 2.1 On known video magnetic tape recorders, the searching for certain positions on the tape is performed by means of a control button, which can be turned and adjusted axially between two positions and can be locked in each of the two axial positions. This known device requires a separate operating mode selection mechanism, demands considerable production effort and allows the direction of tape transport to be changed only by turning the control button back through its neutral position. The novel one-button control is intended to avoid these disadvantages. 2.2 Pressing the rotary button (1), irrespective of its angular position, causes closing of a switch (9), the output signal of which is fed to a microcomputer (8). Each time the rotary button (1) is pressed, the said microcomputer switches off the tape transporting motor (12). Each time after the rotary button (1) has been pressed, a return spring (11) returns it axially into its initial position. 2.3 Searching for certain positions on a tape on video magnetic tape recorders. <IMAGE>

Title: Wellhead structure
IPC: E21B33/00
Filed: 1988-10-12
Granted: 1993-08-04
Abstract: The improved wellhead structure of the present invention includes a casing or tubing string (10) which is sealed to the housing (18) without the aid of elastomeric seals and an internal bushing (14) to assist in providing the tight gripping and sealing engagement between the string and the housing. The structure provides a substantial inner diameter which is unrestricted unless landing shoulder is included in the structure. Also, the internal bushing used with the cold forging of the string into the housing recess improves the gripping and sealing engagement therebetween. In one form the bushing (14) includes a series of external projections which alternate with the gripping and sealing projections within the housing recess and in another form includes a resilient annulus (42) between the interior of the bushing and the string to ensure the uniform application of pressure against the interior of the string. In still another form an internal landing shoulder is cold forged into tight engagement with the interior of the housing which allows full bore operations to be carried through the housing until the landing shoulder is to be installed. Also provided is a wellhead structure with a tieback structure in which the upper end of the casing is cold forged into the interior of a hanger while the casing is supported on slips.

Granted: 1994-03-09
Abstract: To transport entomopathogenic nematodes, it is necessary to store them in a manner such that a significant proportion of them survive after being stored and are reactivated when dispersed in water. The present invention provides storage by mixing an aqueous cream of clean third stage infective juveniles (J3) of nematodes with clay. The clay may be in chip form, or calcined, milled and sieved, but comprises from about 33 per cent (by weight) to 67 per cent (by weight) of the homogeneous mixture. Alternatively a layer of the aqueous cream may be placed on a layer of clay, then covered with another layer of clay. In another variation of the invention, the nematode cream is spread on an absorbent substrate which is then placed on a layer of clay while the relative humidity is reduced to 60 per cent, to dry the nematode cream. Preferred clays are attapulgite clays, diatomaceous clays and kieselguhr. The nematodes are preferably of the family Steinernematidae or Heterorhabditidae.
