Patent CA-3018578-C (CA)
Title: Lignin recovery and furfural production from biomass prehydrolysate streams
Inventor: JEMAA NACEUR
IPC: C07D307/50
Filed: 2017-04-20
Granted: 2020-09-08
Abstract: The present invention relates to a method of producing furfural and extracting lignin from a hemi-cellulosic biomass solution comprising a total quantity of C5 sugars, comprising the steps of heating the hemi-cellulosic biomass solution to a temperature of at least about 200°C; acidifying the hemi-cellulosic biomass solution with acid to produce the furfural in vapor phase; and condensing the furfural to recover furfural in solution, wherein the furfural is produced at a total molar yield of at least 70% of moles of furfural produced/the total moles C5 sugars present in the initial hemi-cellulosic biomass solution. Low molecular weight lignin can also be recovered from the hemi-cellulosic biomass solution prior to furfural production by membrane concentration, acidification, coagulation and filtration.

Title: Method for the powder-metallurgical production of components from titanium or titanium alloys
Inventor: VIEHOFER Ulf
IPC: C22F1/18
Filed: 2017-04-04
Granted: 2021-08-31
Abstract: A method for the powder-metallurgical production of a component from titanium or a titanium alloy is disclosed. In this method, following the customary procedure, first a green part is formed by using metal powder formed from titanium or the titanium alloy and is densified and compacted in a subsequent sintering step. Metal powder of titanium or the titanium alloy with an average grain size of <25 pm is used for producing the green part and the sintering step is carried out at a sintering temperature of up to a maximum of 1100 C. for a sintering at a sintering duration of <5 hours in an atmosphere that is under a reduced pressure in comparison with normal pressure. These measures achieve the effect that the grain structure of the material obtained, and consequently also the material properties, can be selectively influenced. For example, by modifying the sintering conditions of the present method it is possible to create a primarily globular grain structure with high ductility.

IPC: C23F13/06
Filed: 2019-03-21
Granted: 2024-01-02
Abstract: A passive cathodic protection process for preservation of em bedded metallic foundations entails embedding a wrap around a metallic foundation. The wrap has an outer sheath and an inner absorbent mat to be in direct contact with the metallic foundation.  The is also mat hydrophobic. The wrap is subsumed such that an upper edge of the wrap is accessible. An oil-based metallic soap is injected via the upper edge to impregnate the mat. The metallic soap is selected from a set of metallic soaps such that the metal of the metallic soap is more electropositive than the metal of the metallic foundation such that the metallic soap acts as an anodic solution for galvanic exchange with metal within the em bedded metallic foundation for the passive cathodic protection thereof. For example, zinc naphthenate may be selected for steel or aluminium foundation s thereby al lowing for both passive cathodic protection and biocidal action.

Abstract: The invention relates to a movement-dependent stabilisation support system (100) for stabilising a moving body (200), which comprises a plurality of sensors (110), a plurality of actuators (120) and a control unit (130). The plurality of sensors (110) continuously detects movement parameters of the body (200), on which basis the control unit (130) determines whether there is an instability of the body (200). If it is determined that there is an instability, the control unit (130) selects a stabilisation strategy, according to which the actuators (120) are controlled. When controlled, the actuators (120) attached to the body (200) stiffen and limit the freedom of movement of the body (200), such that a movement in the direction of the upcoming unstable state is prevented or suppressed. In this way, the body (200) is supported in its stabilisation and an upcoming fall is prevented.

Title: Moveable isolated rod couplings for use in a nuclear reactor control rod drive
Inventor: MORGAN KENNETH
IPC: G21C7/10
Filed: 2017-07-13
Granted: 2023-10-03
Abstract: Control rod drives include linearly-moveable control elements inside an isolation barrier. Control rod drives move the control element through secured magnetic elements subject to magnetic fields. Induction coils may generate magnetic fields and be moveable across a full stroke length of the control element in the reactor. A motor may spin a linear screw to move the induction coils on a vertical travel nut. A control rod assembly may house the magnetic elements and directly, removably join to the control element. The control rod assembly may lock with magnetic overtravel latches inside the isolation barrier to maintain an overtravel position. Overtravel release coils outside the isolation barrier may release the latches to leave the overtravel position. Operation includes moving the induction coils with a linear screw to drive the control element to desired insertion points, including full insertion by gravity following de-energization. No direct connection may penetrate the isolation barrier.

Title: Secure container for receiving and preventing unauthorized access to articles
Inventor: KAECHELE DARRYL REED
IPC: A47G29/14
Filed: 2020-01-17
Granted: 2023-01-03
Abstract: An apparatus for receiving and preventing unauthorized access to deliveries has an enclosure, a moveable roof on the enclosure, a rotatable basket within the enclosure, and a connecting member coupling motion of the roof and the basket. The basket is rotatable between an upright and an upside-down position. The roof is moveable between an open position in which the basket is accessible and a closed position in which the basket access is blocked. When the roof is moved to the open position, the connecting member rotates the basket to the upright position thereby allowing a user to place the article into the basket. Moving the roof to the closed position rotates the basket to the upside-down position thereby causing the article to drop out of the basket towards the bottom of the enclosure. The enclosure may open into a chute or building for delivering the parcels to a remote location.
