Patent MX-9708957-A (MX)
Title: Conveyor belt.
Inventor: MEEKER WILLIAM A
IPC: B65G17/06
Filed: 1997-11-19
Abstract: A conveyor belt (20), particularly suited to the food processing industry, includes a tension-bearing framework of transversely extending rods (36-38, 141, 168, 172, 177) connected to tension-bearing interconnected links (45) into which is attached a series of loose-fitting modular product support members (23-25, 134, 138). The product support modules include forwardly and rearwardly extending link ends (27, 30) such that successive modules are interfitted with one another. Each of the forwardly and rearwardly extending link ends are provided with slotted longitudinal openings (76, 77, 82) through which the transverse rods extend. The distance between a front wall portion defining the slot in a forwardly extending link end and a rear wall portion defining the slot in an associated rearwardly extending link end is greater than the fixed longitudinal spacing spanned by adjacent transverse rods so as to permit some relative longitudinal movement between the conveyor modules and the rods. In addition, at least one of the modules and the rods are provided with standoff elemnents (84, 136, 143, 170, 174, 179) which define a minimum contact area between the modules and the rods. This limited contact area creates larger openings between the conveyor modules and the rods such that when the conveyor belt is passed through a washing unit (15), washing sprays can effectively reach all surfaces. In addition, since the conveyor modules are permitted to shift longitudinally relative to the rods, this further enhances the elimination of debris trapping zones such that a highly sanitary conveyor belt arrangement is obtained. In addition, unique end cap members (47) are provided to prevent relative rotation between drive links associated with the conveyor belt and the transverse rods.

Abstract: The present invention belongs to the ﬁeld of technologies for designing and preparing novel alloy materials, and in particular, relates to an Nb-element micro-alloyed bulk multi-component alloy with high-temperature resistance and wear resistance, a preparation method therefor, and applications thereof. The multi-component alloy includes the following chemical components at corresponding contents: Al: 2.10-2.24 wt%, Cr: 20.70-20.86 wt%, Ni: 35.20-35.54 wt%, Ti: 19.10-19.46 wt%, Nb: 0.70-0.85 wt%, and the balance of Fe and unavoidable impurities, and the chemical components need to simultaneously meet the following three relations: (1) 24.76 £ Fe/Nb g 31.72, (2) 6.81 5 Fe/(Nb+Al) 5 7.93; (3) 1.04 5 Fe/(Nb+Ti) g 1.13. The multi- component alloy has a uniformly distributed structure, high hardness, and good wear resistance which is 4-5 times higher than that of a traditional wear-resistant material NMSOO in terms of the same hardness. After two-step tempering heat treatment under the same parameters, the NMSOO is reduced in hardness by 58.64-68.93% with respect to its quenched and tempered condition, and the hardness of the material of the present invention is reduced by 31.75-37.74% with respect to its as-cast condition, showing better high-temperature stability.

Title: Adaptive error correction to improve for system memory reliability, availability, and serviceability (ras)
Inventor: KULJIT BAINS
IPC: G11C29/00
Filed: 2021-11-17
Abstract: A memory subsystem includes memory devices with space dynamically allocated for improvement of reliability, availability, and serviceability (RAS) in the system. Error checking and correction (ECC) logic detects an error in all or a portion of a memory device. In response to error detection, the system can dynamically perform one or more of: allocate active memory device space for sparing to spare a failed memory segment; write a poison pattern into a failed cacheline to mark it as failed; perform permanent fault detection (PFD) and adjust application of ECC based on PFD detection; or, spare only a portion of a device and leave another portion active, including adjusting ECC based on the spared portion. The error detection can be based on bits of an ECC device, and error correction based on those bits and additional bits stored on the data devices.

Title: Reinforced concrete foundation post positioning - involves cement and grout pressure-fed beneath post, excess water removal and pressure application around post location
IPC: E02D5/50
Filed: 1978-07-31
Abstract: The method is for the formation of a foundation, whereby a pre-fabricated post is located in the ground. The post (1) after positioning, is pushed over slightly to allow cement and grout material (2) to be poured into the hole beneath it under pressure.

IPC: C02F3/28
Filed: 1980-11-07
Abstract: A purification process for waste water and/or waste water sludge, comprising a methane fermentation and subsequent oxidation of the reduced compounds present in the effluent of the methane fermentation by means of aeration, whereby the sulphide from the effluent of the methane fermentation is used as electron donor by the denitrification and whereby the residual reduced compounds from the liquid effluent from the methane fermentation not until the subsequent next step are oxidized by aeration. 
<??>In this way the suiphldes, produced by the methane fermentation, are used in appropriate way and simultaneously converted in non troublesome or innocent sulphate. 
<??>In the liquid effluent, remaining after denitrification, the ammonia, which was occurring in the effluent is still present; this ammonia is subsequently oxidized into nitrate at the aeration, whereby the sulphide cannot interfere with, as this sulphide was converted in sulphate with the denitrification. As no sulphide is more present, the aeration is demanding less air and aeration may moreover be more simple. 
<??>The hydrogen suiphide from the gas formed by the methane fermentation also may be used for this purpose, giving in this way the greatest utility of the products formed with the methane fermentation, while the gas is purified in a simple way.
Patent NL-8102226-A (NL)
IPC: H03M1/80
Filed: 1981-05-07
Abstract: In a digital-to-analog converter for bipolar signals all the bits change when the signals pass through the zero level. This results in a poor signal-to-noise ratio owing the small signal and the large noise contribution by the switching transients. The invention proposes to add a digital number to or subtract it from the digital input signal as an offset. As a result of this, the switching point is shifted towards a higher amplitude, which improves the signal-to-noise ratio and the distortion in the case of digital audio signals.

Abstract: Electrolytic tinning is performed in a tinning line having a series of tinning tanks (4) through which metal strip moves while electrolysing current is passed, and having at at least one of the entry side and the exit side at least one buffer apparatus for storing a variable amount of the moving strip. In order that some speed variation in the tinning tanks can occur, allowing the use of lower capacity buffer apparatuses (5), the current passing in each tinning tank (4) is adjusted during tinning for portions of the strip. The current is calculated for a given strip portion by(a) determination of a value for the thickness of the tin layer on entry to the tinning tank;(b) determination of a value for the desired thickness on exit from the tinning tank;(c) from the difference of these values determination of a value g for the desired increase in the tin layer thickness in the tinning tank; and(d) determination of the instantaneous required value of the current I in the tinning tank in dependence on the value g and the speed v of the strip through the tank.
