Title: Tangental type differential detector for pulse shaped pi/4 shifted differentially encoded quadrature phase shift keying
Inventor: CHENNAKESHU SANDEEP
IPC: H04L27/233
Filed: 1992-04-09
Abstract: RD-20,184 TANGENTAL TYPE DIFFERENTIAL DETECTOR FOR PULSE SHAPED .pi./4 SHIFTED DIFFERENTIALLY ENCODED QUADRATURE PHASE SHIFT                      KEYING                ABSTRACT A digital radio receiver for synchronization of radiowave transmissions for digital and analog FM signals in TDMA systems such as cellular telephones uses a tangent type differential detector that minimizes the bit error rate. The differential detector employs an A/D converter circuit that samples a received signal, a sorter circuit that selects a predetermined number of samples to be used in the decoding, a sample and phase adjustment circuit that allows for a carrier phase adjustment and sample timing adjustment, a divider circuit that eliminates the need for a conventional limiter by causing a ratio of amplitudes to be processed instead of absolute signal amplitudes, an inverse tangent circuit creates a decoded phase angle from the ratio, a delay circuit and a summer circuit that create a differential signal, a modulo-2.pi. correction circuit that corrects for wrap-around errors about the real axis, and a four-phase decoder circuit to decode the signal into a pair of bits.      An adjustment circuit minimizes phase error between a reference  sequence of symbols and the decoded symbols by simultaneously adjusting the sample timing and carrier phase adjustments.  The differential detector can be modified to decode conventional analog FM radio broadcasts by processing more samples per symbol, deactivating the adjustment circuit, and the SPA circuit, and bypassing the four-phase decoder.

Title: Pressure relief hold open apparatus
Inventor: VINCENT WILLIAM
IPC: E04B1/92
Filed: 1992-08-24
Abstract: A pressure relief panel assembly for protecting a building against over-pressure caused by explosion.      The assembly has a panel pivotally connected to a frame and held by a calibrated magnet and striker set which releases when a predetermined over-pressure occurs. A cable restraint attached to a shock absorber, or a linkage of two arms attached to a shock absorber, limits the extent to which the panel can blow open. A spring mounted on one of the arms catches the other arm when the panel has blown open, preventing the panels from re-closing and thereby preventing implosion damage to the building. Alternatively, or additionally, the panel, after opening, may be held partly open by a stop bar which pivots to prevent the panel from fully closing, to prevent implosion damage to the building after the explosion.

Title: Complete gene (cefg) encoding the acetyl-coa: deacetylcephalosporin c acetyltransferase of cephalosporium acremonium, its isolation and use
Inventor: MARTIN MARTIN JUAN F
IPC: C12N15/09

Abstract: Abstract                   HOE 32/F 099 The complete gene (cefG) encoding the acetyl-CoA: deacetylcephalosporin C acetyltransferase of Cephalosporium acremonium, its isolation and use.     The gene (cefG) encoding the acetyl-CoA: deacetylcephalosporin C acetyltransferase (DAC-ATF) of Cephalosporium acremonium (syn. Acremonium chrysogenum) C10 has been isolated. It contains two introns and encodes a protein of 444 amino acids with a molecular weight of 49269 that correlates well with the molecular weight deduced by gel filtration (Mol. weight 52 000 ? 1 000).          The cefG gene is linked to the cefEF gene (encoding the bifunctional deacetoxycephalosporin C synthase/hydroxylase) but it is expressed in the opposite orientation to the cefEF gene. The isolated cefG complements the deficiency of deacetylcephalosporin acetyltransferase e.g. in the non-producer mutant C acremonium ATCC 20371 and restores cephalosporin biosynthesis in this strain. The cefG is therefore useful to improve cephalosporin C production.

Title: Apparatus and method for manufacturing ink jet printed products and ink jet printed products manufactured using the method
Inventor: MIURA YASUSHI
IPC: D06B11/00
Filed: 1993-07-26
Abstract: An object is to provide ink jet printed products superior in the image quality such that ink jet printing onto the cloths satisfy the various conditions regarding the density, resolution, blurring, graininess of dot. To accomplish this object, when an image is formed by a number of dots obtained by discharging the ink from a print head to attach the ink onto the cloths, the ink amount dis-charged from the printing head onto the cloths is controlled to produce ink jet printed products so that the average value of equivalent circle diameter for each dot after image formation may be three-fourths or lest the average value of diameters of fibers constituting said cloths. Thereby, ink jet printed products excellent in image quality can be obtained with blurs reduced and high graininess of dot.
