摘要:
A feeder box for dumping bulk materials onto a conveyor of a mobile transfer station comprises at least one feeder device located adjacent a side of the conveyor, each feeder device including a box compartment and a support structure for the box compartment, the box compartment being pivotable with respect to the support structure so as to tilt towards the conveyor to dump bulk materials onto the conveyor.

A transfer station which includes an elongated main frame, a conveyor movably mounted in the elongated main frame; a feeder box comprising opposite feed devices connected to opposite sides of the elongated main frame, each feeder device including a box compartment which can be tilted to discharge debris deposited therein onto the moving conveyor; a crusher mechanism for crushing debris carried thereto by the moving conveyor; a discharge chute for discharging the crushed debris into a hauling device; and lifting devices attached to the elongated main frame to lower it onto the ground and place the transfer station in a lowered, operational mode, or raise it above the ground and place the transfer station in an elevated transport mode. Once the transfer station is in its elevated, transport mode a caterpillar tractor can be positioned under the elongated main frame to transport the transfer station to another processing location.

An impact roll crusher for grinding up material, for example in mineral mining, employs a roll equipped with impact heads which co-operates with part of a conveyor transporting the material. The roll is rotatably mounted in a housing and a hood is connected to the housing to deflect and discharge the crushed material. The crusher roll is driven by a belt coupled to pulleys on the roll and on a drive motor shaft. The drive motor is supported by a bracket pivotably mounted on an inclined baffle wall of the hood. The roll drive adopts a position below the upper surface of the crusher housing. A tensioning device operable to adjust the tension in the drive belt is coupled to the bracket and adjusts the pivotable movement of the bracket.
摘要:
The invention relates to a method and a device for determining the glucose concentration in tissue fluid whereby test values for glucose and for an endogenous reference substance are detected in a sample liquid obtained by microdialysis, microperfusion or ultrafiltration, and the glucose value is corrected in accordance with the test value for the reference substance. The recovery rate for glucose is determined from a non-linear relationship with the recovery rate for the ionic reference substance, and the test value for glucose is corrected therewith. In addition, the concentration of lactate and/or pyruvate is used as a further reference substance in the sample liquid to make further corrections.

A rock bolt stabilizer device which can be arranged in boreholes for stabilizing rock and similar host environments in mining and tunneling. The device is adapted to perform the function of a rigid profile anchor under predetermined stress conditions, and is also adapted to perform the function of an expansion anchor under given stress conditions. The device generally comprises an anchor member with mix end which can be secured near the base of the respective borehole by means of a cementitious composition. For tensioning, the other end of the anchor member can carry a bearing plate, a spacer, and a fastener for tensioning. The device also includes a sleeve which performs the function of a rigid anchor, and the sleeve substantially surrounds the anchor member. An increased armoring and anchoring efficiency is achieved with the device.
摘要:
Glucose analysis instrument for diabetics, comprising a measuring device for determining glucose concentration values, a displaying device for displaying glucose concentration values, a signaling device for generating a reminder signal, and a control and evaluation device that comprises a processor and a data memory and is used to determine reminder times at which the signaling device is actuated. Event data are stored in the data memory, the event data containing information on events occurring in the life of a user of the glucose analysis instrument and on the time of occurrence of such events. The reminder times are determined by means of a reminder time determination algorithm taking into consideration event data from at least one previous day.

摘要:
In rock or roof bolts, in particular combined rigid profile and stretch or strain roof bolts, the bolt bar, except for the bar tip is surrounding by a sheathing tube and the end thereof projecting out of the drillhole mouth is made tensionable with respect to the rock by means of an anchor plate and a screw means. To ensure the immediate loadbearing capability of such a roof or rock bolt, in particular in the filling mortar method, at least one portion (5) of the sheathing tube (3) is provided as expansion element with cutouts (7) distributed into slots (8) and the bolt tip (2) is formed as abutment.

A roof support for coal-mining apparatus or other tunnel-excavating equipment has a shield plate with several rearwardly diverging and deepening longitudinal grooves in its upper surface. The grooves are designed to carry off detritus as the support advances and are spaced closely enough to form ribs therebetween adapted to crush larger chunks of overburden landing thereon.
