摘要:
A process and apparatus for the preparation of a modified lignocellulosic material by treating the lignocellulosic material in a first activator zone having an atmosphere of one or more acid anhydrides in vapour form in a gas at a gauge pressure of 0-50 kPag and a temperature of 100-160° C., and then treating the lignocellulosic material in a second reactor zone having an atmosphere of a gas at a gauge pressure of 0-50 kPag and a temperature of 120-190° C., thereafter stripping the lignocellulosic material with steam or water in a stripper zone, and optionally further processing. The process is more efficient as compared with the prior art processes by providing a better access of the acid anhydrides to the sites of the reactive lignocellulosic hydroxyl groups (—OH), which are located on the internal surfaces of pores and capillary channels in the lignocellulose. Furthermore, the apparatus is relatively simple. This makes the inventive process and apparatus suitable for a cost-efficient preparation of modified lignocellulosic fibre in industrial scale.

The disclosure relates to a portable system for distributing building materials comprising a motor vehicle which can be in the form of a truck. Disposed on a flat bed of the truck is at least one container coupled to the motor vehicle. The container can include at least one stirrer wherein the stirrer is for stirring a first component in the container. There can be at least one mixer coupled to the motor vehicle wherein the mixer is for mixing at least one liquid component with the component in the container to form a slurry. Once the slurry is formed, it can be fed to at least one distribution feeder which is then used to feed materials to a job site. This system can include a computer for controlling the mixer, and the distribution feeder to control the distribution of this slurry material. The disclosure can also relate to a process for creating the dry mixture, the slurry and then distributing this slurry so as to create a building component such as a floor. This process can be monitored by a computer, wherein the computer can be used to generate a series of reports such as a job report, a quality control report or a bill.

The invention relates to a method of making frozen products with a characteristic form from at least one flowable type of material, the frozen products including edible ice products such as ice cream sticks, ice lollipops, ice dessert or the like. The method includes placing a first quantity of the flowable type of material in a first mould or moulding part and cooling the material of the at least one first mould or moulding part in order to create a basic frozen form of the product. Further, the method includes forming the frozen form of the product into a characteristic form, this forming including modification of the product in a second mould or moulding part, the second mould or moulding part basically having the contours of the characteristic form.

A method of advancing molds (5), after pouring to form castings (9) in the casting cavities (8), leaving a foundry plant comprising a mould-making station (A, 1-4) and a pouring station (B,7), the molds (5) leaving the plant in the form of closely juxtaposed mold parts (5) with the castings (9) in casting cavities (8) at the mainly vertical parting surfaces between successive molds (5), the latter constituting a mold string (F), in which each mold (5) occupies a given length (S) in the longitudinal direction of the mold string (F), the latter after having passed a precision conveyor (6, 16) being transferred to a second conveyor (10, 16, D). Each time the second conveyor (10) receives a mold (5) from the mold string (F), the second conveyor (10) is advanced in a controlled manner through a greater distance (S+s) than the length (S) of the individual mold (5) in the mold string (F), so as to produce an interspace (s) on the second conveyor (10) between consecutive molds (5) along the mainly vertical parting surfaces. The new method makes it possible to improve cooling, shorten the conveying distance, and reduce the production of dust.

Systems, methods, and computer program products for managing and networking schedules and calendars of events are provided herein. A method of a managing, networking, and presenting calendars, schedules and events can include uploading from one or more computing devices of one or more users at least one of calendars of events, schedules of events or individual events to a scheduling event networking system. The method can also include grouping two or more calendars of events, schedules of events or individual events into one or more umbrella groupings based on instructions received from one or more computing devices of one or more users. The method can further include displaying on one or more computing devices of one or more users a layered network of one or more of the calendars of events, schedules of events, individual events, or umbrella groupings on the scheduling event networking system based on user preferences.
摘要:
There is disclosed a system for depositing building materials comprising a motor vehicle, a container comprising a material depositing system and at least one device for removing the container from the motor vehicle. The device can comprise one or more outriggers which are adapted to remove the container from the motor vehicle and which can be used to deposit the container on a job site. In addition there is a system which includes a hydraulically controlled crane and silo doors for allowing material to be automatically added to containers for mixing building materials.
