  • Publication number: 20160201424
    Abstract: A wire line tool trap has a central housing with an axial passage. The passage is sized and shaped to movably receive a cable and tool. A pair of housings have an interior that opens to the passage of the center portion. Each of a pair of catch blocks are disposed in a respective lateral housing. Each catch block has an inside catch end with an under face and an upper face. When the catch blocks are fully inserted, a passage is defined to permit the wire line to pass therethrough. The under faces form a concavity, and the upper faces form a top land. The concavity permits a tool to urge the catch blocks apart and into a retracted state. Thus, the tool can drawn upwardly between the catch blocks. The top land retains a tool thereon and prevents the downward passage of the tool past the blocks.

  • Publication number: 20160169093
    Abstract: An exhaust-gas turbocharger with a compressor with a charge pressure control device. An actuator is provided which moves a control rod arrangement. The control rod arrangement is in turn rotatably connected to a lever. The charge pressure control device is actuated by the lever. A pin is arranged on the lever. The control rod arrangement has a bushing which is pushed onto the pin. The connection between pin and bushing constitutes a rotatable connection for enabling the lever to be actuated by the control rod arrangement. This arrangement is very simple to produce and very simple to assemble because the bushing must merely be pushed onto the pin.

  • Patent number: 9011982
    Abstract: A method for a layer-wise manufacturing of a three-dimensional object has a first step of providing a layer of a material in powder form or a liquid material on a support or a layer that has already been solidified at selected positions previously and a second step of directing a focussed photon or particle beam (8?) selectively at selected positions of the layer. In the second step, the photon or particle beam is selected such that it brings about a change of the absorption of the material when hitting the layer. After the termination of the second step, a third step is carried out, in which the layer is irradiated by means of electromagnetic radiation (18?) such that the material is homogenously solidified at those positions of the layer that correspond to the cross-section of the object to be formed.

  • Publication number: 20140119250
    Abstract: In general, the present invention relates to systems and methods to facilitate timing recovery and loop timing operations in a TDD communication system with significantly varying intervals of inactivity between periods of transmission. According to certain aspects, to facilitate timing recovery, embodiments of the invention define a maximum period of inactivity for each mode of transmission and associated “timing keep alive” signals during and/or between transmissions to assist the timing recovery function in the receiver. In embodiments, the receiver selects the desired format of the “timing keep alive” signal. According to further aspects, the timing recovery mechanisms of the invention maintain power saving objectives of G.fast, where power dissipation varies near linearly with traffic demand.

  • Patent number: 8490902
    Abstract: In order to detect a lack of coffee beans in a grinder unit of a coffee maker, a method is suggested in which the level and/or the spectrum of an oscillation generated by the grinder unit during its operation is measured. The level of the oscillation and/or the nature of the spectrum are used to decide whether or not coffee beans are present in the grinder unit. Preferably, the level of oscillation of the housing of the coffee grinder unit is monitored. If the level changes by more than a preset value and/or falls below a reference value, it is decided that coffee beans are lacking.
