Abstract: Systems, methods, and non-transitory computer readable media are provided for providing a redundancy tool for performing transactions. A transaction to be performed on a data stored in a database may be received. A timestamp may be assigned to the transaction. A lock may be assigned on the timestamp. The transaction may be performed on the data. The lock may be refreshed while performing the transaction on the data. A validity of the lock may be checked at after performing the transaction on the data. Responsive to the lock being valid, a result of performing the transaction on the data may be committed.

Abstract: A connector includes a housing, a terminal arranged in the housing, and an elastic cantilever on an outside of a top wall of the housing and extending along a length direction of the housing. The elastic cantilever has a pair of sides opposite to each other in a width direction of the housing. A snap protruding along the width direction is formed on one of the sides of the elastic cantilever. The snap engages a mating snap formed on a mating housing of a mating connector to lock the connector and the mating connector together.

Abstract: The disclosure relates to a front cover of a vehicle-mounted camera, a vehicle-mounted camera device, and a vehicle. The front cover of a vehicle-mounted camera includes: a lens assembly, having a lens mount and a lens set including at least one lens; and a cover body, having an end surface in abutting joint with the lens mount and a through mounting hole, wherein the lens set is inserted in the mounting hole with a clearance reserved therebetween, such that the lens mount fixedly abuts against the end surface by means of a connecting medium, and an inner wall of the mounting hole and/or an outer wall of the lens set is provided with an accommodating portion, thus the connecting medium fills the accommodating portion and is wedged between the lens set and the mounting hole.

Abstract: A portable door guard for sliding over a hinge of a door, the portable door guard comprising a body comprising a hollow cylindrical section including an opening gap along the length of the hollow cylindrical section on a stationary section of a back face of the body, the hollow cylindrical section comprising a “C” shaped profile capable of fitting over a hinge, wherein the hinge comprises a barrel, a first wing, and a second wing, the first wing being mounted on a door frame, and the second wing being mounted onto the door, and the barrel holding the first wing and the second wing together while acting as a pivot. The portable door guard further comprising a body section configured to impede the door from opening more than a given amount, the body section capable of being extended and shortened.

Abstract: A portable door guard used to secure the door at the hinge, particularly the wings of the hinge. The portable door guard comprises a retractable, non-permanently fixed device that can be secured around the hinge of the door from the inside to prohibit the door to open more than a gap. The portable door guard includes a center area designed to grip the hinge to limit the swinging movement of the hinge and adjusting means to configure the size of the gap.

Abstract: An apparatus includes: a wire having a proximal end and a distal end; and a body being fixedly coupled to the proximal of the wire and having at least two apertures, each aperture for receiving and locking the distal end of the wire at different times such that when the wire is locked in one of the apertures it cannot be removed without destroying the apparatus, wherein the distal end of the wire is operable to pass through one or more apertures of an object and lock in each of the apertures at different times such that the body retains the wire in engagement with the one or more apertures of the object and maintains the apparatus locked to the object.

Abstract: An apparatus includes: a head; a metal wire having a first end coupled to the head and a second end coupled to a stop member; and a body having a cavity for receiving and locking the head such that when the head is locked in the cavity it cannot be removed without destroying the apparatus, wherein the head and the metal wire are operable to pass through one or more apertures of an object and the head is operable to lock in the cavity such that the body and the stop member retain the wire in engagement with the aperture and maintain the apparatus locked to the object.

Abstract: An apparatus and a process for reclaiming fuel oils from waste oils. The apparatus and process is characterized in that waste oils are thermally cracked by combination of high pressure and vacuum in a sequence at high temperature. However, rapid thermal cracking is performed at even lower temperature of 300˜350° C. than at 400˜450° C. of conventional batch method. The semi-continuous method with bleeding process is employed and accordingly no pause stage becomes necessary to physically collect ash cake from the thermal cracking vessel as experienced from the conventional batch process. The ash cake contents drops from 5% of conventional method to 1.4% since slow reaction is a cause for oxidation problem which is related with formation of tar compounds and production rate of #2 diesel fuel oil increases 3 times more than batch process.

Abstract: An apparatus includes: a base having at least one surface lying substantially in a base plane; a first member extending substantially perpendicularly from the surface of the base and defining an aperture therein; and a second member having a proximal end coupled to the surface of the base and a distal end, the second member defining a second plane extending transversely from the base plane of the base at least toward the aperture, wherein the orientation of the second member biases the second member toward the first member such that an article may be gripped therebetween.

Abstract: A method for removing contaminants from thermally cracked waste oil is disclosed. The thermally cracked oil is mixed with methanol at an elevated temperature and pressure to accelerate the whole extraction process and to obtain better productivity and better quality of end product oil. The contaminants in methanol liquid phase are separated by flash evaporation and the resulting methanol solvent is recycled.

Abstract: Disclosed is an apparatus and a process for reclaiming fuel oil from waste oil. The apparatus comprises a thermal cracking unit for cracking the high boiling hydrocarbon material into lighter, lower boiling, material so as to separate hydrocarbon vapor products from viscous materials; a condenser/heat exchanger for condensing the hydrocarbon vapor products to the liquid state; a fuel stabilization unit for chemically treating the condensates so as to give a oil product and solid sediment; and a polishing unit for forming a high quality fuel oil by physically removing solid contaminants. According to the present invention, high quality fuel oil can be obtained together with an environmentally innocuous solid ash cake, through a simple and efficient process.
