Title: Closed entry socket contact assembly
Inventor: WELSH DAVID EDWARD
IPC: H01R13/10
Filed: 1991-09-06
Granted: 1995-11-21
Abstract: A high reliability socket contact assembly is provided, of the type that has a seamless exterior, which has tines with closely spaced initial and final points of pin contact engagement, and which has a closed entry region limiting the size of pin contacts that can be inserted, which can be constructed at low cost.  The assembly includes a seamless barrel (12, Fig. 3) having a cylindrical cavity (16) extending into its front end, and a clip (20)  formed of sheet metal rolled into a tube and lying in the cavity.   The clip has a rearward portion (32), tines (42a-42d) extending forwardly from the rearward portion and having free forward tips, and a forward portion.  The tips (56) of the tines have radially inner edges (60) lying on a first imaginary circle, and the forward portion of the barrel forms a closed entry region (72) having an inside diameter no greater than the diameter of the first imaginary circle, to prevent entry of pins of a diameter that could damage the tines.  In one barrel (Fig. 3), the forward barrel portion has a flared front part (80), with the narrowest part of the flare forming the closed end region.  In another clip, (Fig. 9) the sheet metal forming the clip is thinner at the tines than at the forward portion (146) lying forward of the tines.

Abstract: The message management system utilizes a flat file (20) on mirrored disk for storing fixed-length Message Segments (MS) of variable-length Messages to be managed by the system. Inconsistencies between mirrored copies of data are tolerated and cor-rected. Message Management includes Storing, Retrieving and Deleting Messages in response to commands from clients. Each Message Segment in the flat file is stored in a record containing the Message Segment data and Recovery Information (RI). A data base (21) for accessing the Message Segments in the flat file is maintained on system disk. The Recovery Information is such as to permit recovery of the data base from the Recovery Information in the flat file if the data base is obsolete, lost or corrupted. TNAUDIT file is utilized to determine that the data base is synchronized with the flat file. If data base inconsistency is detected, the data base is rebuilt from the Recovery Information.

Granted: 2002-01-29
Abstract: Novel alkylenediammonium diclavulanate derivatives, process for the preparaiton thereof and use thereof.    A novel process for the preparation of calvulanic acid and pharmaceutically acceptable salts thereof, such as potassium clavulanate, is described.  According to the novel process, crude clavulanic acid is reacted with substituted alkylenediamines of the formula   wherein the substituents R1, R2, R3 and R4 denote - a hydrogen atom, - a straight-chain or branched-chain alkyl group having 1 to 8 carbon atoms or - a hydroxyalkyl group having 2 to 4 carbon atoms and NR1R2 and/or NR3R4 jointly denote a heterocylic ring having 3 to 6 methylene groups bound to a nitrogen atom, one of these groups being optionally substituted by an oxygen or a sulphur atom or by an imino group and R5 denotes a hydrogen atom, or a methyl group and n denotes an integer from 1 to 3, to produce novel alkylenediammonium diclavulanates of the formula   The obtained compounds are optionally isolated and converted with alkali alkanoates, such as potassium 2-ethylhexanoate in isopropanol, to potassium clavulanate. Because of their high inhibitory action against beta-lactamases and because of a significant synergistic action in combination with the beta-lactam antibiotics from the group of penicillins and cephalosporins, clavulanic acid and pharmaceutically acceptable salts thereof are valuable compounds for the preparation of galenic compositions, which are active in the treatment of infectious diseases induced by numerous gram-positive and gram-negative microorganisms.

Title: Selectively called radio receiver in which bit rate detection is controlled with a predetermined range
Inventor: IDE MOTOKI
IPC: H04W88/02
Filed: 1993-10-12
Granted: 1999-12-28
Abstract: In a selectively called radio receiver in which a demodulated signal of a specific bit rate is produced with battery saving kept in synchronism with the demodulated signal, a bit rate detecting unit detects the bit rate with a controllable sensitivity while the synchronism is lost. A bit rats detecting control arrangement controls the sensitivity within a predetermined sensitivity range, The bit rate detecting unit may misdetect the bit rate with a variable misdetection rate which is accumulated to an incremented amount from an initial amount representative of no disdetection while the synchronism is lost. The bit rate detection control arrangement may decrmement the misdetection rate to the initial amount when the incremented amount reaches a predetermined amount, Alternitively, the bit rate detection control arrangement may control the misdetection rate between a greater and a smaller amount and then cause the misdetection rate return to the initical amount. In either event, the bit rate detection control arragement controls the sensitivity within a predetermined range,

Abstract: A metal-air power supply which provides improved control over air flow is provid ed. The reactant air and cooling air inlets are separate from one another and isolated from the exhausted reactant and cooli ng portions of the air flow, the reactant air flow is limited to a volumetric flow rate sufficient to provide from about 3 to about 10 times the stoichiometric amount of oxygen necessary to produce a predetermined level of current from the cell, and a total volumetric flow rate of air sufficient so that the cooling portion of the air flow has a volumetric flow rate from about 10 to abou t 1000 times the volumetric flow rate or the reactant portion of the air flow is provided. This limits the flow rate of the reactant a ir over the cathode, isolates the cooling air flow from the reactant air flow, and maintains the temperature of the metal-air cell at a low level without exposing the air cathode to an excessive air flow rate to reduce the likelihood of drying out the metal-air cel ls, reduce the exposure of the battery cell to contaminants, and minimize the effects of temperature on the vaporization of wat er within the cell. In a preferred embodiment, the power supply housing and the metal-air cell case form part of the air plenums. A subst antially leak-proof metal-air cell is also disclosed.
