Filed: 1988-05-13
Abstract: The present invention involves an inner shoe material with adsorbent properties, whereby activated carbon particles are fixed as the adsorbent material by means of an adhesive substance in a punctiform manner to the side of the material facing away from the foot. The inner shoe material of the invention can be designed as inside lining, insoles, slipsoles, as inner sole of the shoe or as a covering material for the inner sole of the shoe. The inner shoe material of the invention can e.g. be used for combat boots with integrated C-protection or for safety boots with protection against aggressive chemicals. The inner shoe material has the advantage that it exhibits a high degree of scuff resistance on the one hand and the adsorbent activated carbon is freely accessible to the substances to be adsorbed, on the other.

Title: Method of forming a solder layer on pads of a circuit board and method of mounting an electronic part on a circuit board
Inventor: FUSE KENICHI
IPC: B23K35/22
Filed: 1990-11-26
Granted: 1993-01-12
Abstract: Abstract of the Disclosure A paste-like composition containing a lead salt of an organic acid and tin powder is applied on a pad array portion of a citcuit board.  Then, the paste-like compo-sition is heated so as to cause precipitation, thereby forming a solder layer formed of an Sn-Pb alloy substan-tially only on pads.  This precipitation is performed in a state that a liquid pool is formed on the pad array portion when the paste-like composition is liquified by heating, and the tin powder is settled in the liquid pool.  When an electronic part is to be mounted on the pads, first, preparatory solder layers are formed on the pads by the above-mentioned precipitation process. After a paste-like composition is applied on the prepar-atory solder layers, the electronic part is put on the paste-like composition.  Then, the paste-liks composi-tion is heated, thereby soldering leads of the elec-tronic part with the pads.

Title: Atomic interferometry gyroscopes, accelerometers and gravity gradiometers
Inventor: CLAUSER JOHN FRANCIS
IPC: G01P15/14
Filed: 1990-03-05
Granted: 1996-01-30
Abstract: The invention is a neutral atom (and/or molecule) matter-wave interferometer (and/or set of interferometers) that can be used as a ultra-sensitive inertial and/or gravity sensor. A pair of interferometers with different energies and/or  masses  can  perform  simultaneous  independent measurements of rotation and acceleration.Interferometers with paths that follow a figure-eight pattern yield a gravitational  gradiometer.  Diffraction  gratings  are employed as beam splitters. Such gratings may consist of apertures (S1,S2,G1,G2,G3,G4,G5,G6) in a sheet of solid material,   near-resonant  standing-wave  laser  beams (97,99,101), or crystal faces (179). Path curvature due to acceleration and rotation is canceled by magnetic and/or electric field gradients that produce an effective levitation  of  slow  atoms.  A  feedback  system  that maintains an interferometer phase null is employed with its error signal yielding the inertial effect signals.

Granted: 2001-01-02
Abstract: In a process for coating the blades of a rotating, thermal machine, said blades undergo a first cleaning process in the operating state of the machine, i.e. "on line", the appropriate agent fox this, which depends on whether the blades are uncoated or coated, being mixed in with the air stream to the compressor.      After switching off the machine and opening the same, the blades undergo in the stationary state, that is to say in the bladed state of the corresponding rotor or stator, a preparation process for the subsequent treatment stage. According to requirements, this preparation process may, for example, consist in the blades being immersed in a vibrating erosive bath. The actual coating of the blades takes place by means of a high-speed flame spraying process, in which the protective coating is sprayed onto the surface of the base material at a particle velocity of at least 300 m/s. Thereafter, the blades also undergo an after-treatment which, according to requirements, serves to reduce the surface roughness and/or is provided to apply a top coating.

Granted: 1999-11-23
Abstract: In order to test a closed container having at least one flexible wall area regarding a leakage by an increasing of the inner volume of the container and a measuring of a correspondingly caused changed measured value at least one outer wall area of the container is exposed to the atmosphere of a medium having a pressure which is larger than the pressure produced by the increase of the volume of the container if such has no leakage.

Title: Method and apparatus for dynamic channel bandwidth allocation among multiple parallel video coders
Inventor: HANG HSUEH-MING
IPC: H04N7/26
Filed: 1991-08-26
Granted: 1996-04-23
Abstract: A dynamic channel allocation unit for specifying a bit rate for each video coder in a set of parallel video coders comprising an overall video coder is disclosed.  The dynamic channel allocation unit is supplied from each individualvideo coder with an average frame quantization  step size for the previous frame and the average number of bits produced per pel. For the current image frame the dynamic channel allocation unit computes a set of channel sharing factors, i.e., the percentage of the total channel bandwidth to be allocated to a particular video coder. One channel sharing factor is computed for each individual video coder. Individual members of the set of channel sharing factors may be further refined to reflect the prior history of the channel sharing factor for their corresponding  coder. Additionally, the set of estimates may be normalized to reflect the actual number of bits that can actually be produced by each individual video coder.

Title: Linear prediction speech coding with high-frequency preemphasis
Inventor: NAKAMURA MAKIO
IPC: G10L19/038
Filed: 1991-09-25
Granted: 1996-03-12
Abstract: In a speech encoder, high-frequency components of input digital speech samples are emphasized by a preemphasis filter (11). From the preemphasized samples a spectral parameter (ai) is derived at frame intervals. The input digital samples are weighted by a weighting filter (13) according to a characteristic that is inverse to the characteristic of the preemphasis filter (11) and is a function of the spectral parameter (aj). A codebook (18, 19) is searched for an optimum fricative value in response to a pitch parameter that is derived by an adaptive codebook (16) from a previous fricative value (v(n)) and a difference between the weighted speech samples and synthesized speech samples which are, in turn, derived from past pitch parameters and optimum fricative values, whereby the difference is reduced to a minimum. Index signals representing the spectral parameter, pitch parameter and optimum fricative value are multiplexed into a single data stream.

Abstract: Lactoferricin (Trade Mark), also called LFCIN (Trade Mark), a potent antimicrobial peptide, is produced by contacting an enzymatic hydrolysate of bovine lactoferrin or any mixture of peptides containing lactoferricin preferably with a butyl moiety-containing hydrophobic interaction chromatography medium, or alternatively with a carboxymethyl moiety-containing cation-exchange chromatography medium, rinsing the medium to remove unbound peptides, desorbing the lactoferricin solution at constant pH, and desalting the desorbed solution. The utility of the process is illustrated, for example, as follows. An enzymatic hydrolysate of bovine lactoferrin (600 g) was contacted with 3000 ml of BUTYL-TOYOPEARL 650 M, the medium was rinsed with water, and then with McIlvaine (citric acid-sodium phosphate) buffer at pH 7Ø, and lactoferricin was desorbed with Mcllvaine buffer at pH 5Ø The desorbed material was desalted by contacting it with BUTYL-TOYOPEARL 650 M, rinsing the medium with water to remove the buffer salts, and desorbing the lactoferricin with 10 mM HCl. A yield of 10.5 g of 99% purity was obtained. The product has applications as a safe and effective antimicrobial agent for use in oral hygiene products, cosmetics, clinical foods, etc.
