Title: Tensioner pad assembly.
Inventor: TERENCE WILLEM AUGUST VEHMEIJER
IPC: F16L1/23
Filed: 2015-05-18
Abstract: The invention relates to a tensioner pad assembly, adapted to be mounted on an endless track of a tensioner to frictionally clamp an elongated product supported and moved by the tensioner, the pad assembly comprising a carrier member and a pair of gripping members, which gripping members can with their carrier member mating surfaces be mounted in multiple discrete gripping positions on gripping member mating surfaces of the carrier member. The mating surfaces form interlocking structures adapted to transfer a squeeze force from the carrier member to the gripping members. The interlocking structures provided on the carrier member define the multiple discrete gripping positions. Furthermore, the gripping member mating surfaces extend at an angle relative to each other, such that the multiple discrete gripping positions differ in their distance to the base portion as well as in their distance to the imaginary plane of the carrier member.

Abstract: Een melkdierbehandelingsinrichting voor uitvoeren van een diergerelateerde handeling op een melkdier omvat een optische dierdeeldetectieinrichting voor optisch detecteren van een dierdeel en voor genereren van een informatiesignaal betreffende het gedetecteerde dierdeel, en een besturing voor uitvoeren van de diergerelateerde handeling op basis van de positie. De optische dierdeeldetectieinrichting omvat een lichtbron, een behuizing met een venster en erin opgenomen een optische detector, en een detectorbesturing voor de dierdeeIdetectieinrichting. De behuizing omvat voorts een draaibaar element, en de detectorbesturing is ingericht voor uitvoeren van een ontwasemhandeling onafhankelijk van het detecteren. Aldus kan eventueel op het venster gecondenseerde waterdamp verdampen door de interne luchtstroom, die kan zijn verwarmd door in de behuizing door onderdelen opgewekte warmte. Aldus kan een helderder beeld voor de optische detector beter worden gewaarborgd.

Title: System with a process chamber having two process compartments with a vacuum pressure barrier in between and method for operating such a system
Inventor: SHOU PENG
IPC: H01L31/18
Filed: 2021-11-12
Abstract: The present invention proposes a system having a process chamber with two process compartments with a vacuum pressure barrier in between and a method for operating such a system. The system comprises a process chamber with a first process compartment and a second process compartment separated from each other by an intermediate wall, a first gas source, a process pump and a transport apparatus. A slit is formed which penetrates the intermediate wall and provides a flow pass for gas from the second process compartment to the first process compartment and a transport path for substrates from one of the first or second process compartment to the other one of the first or second process compartment. An ambient pressure within the first process compartment is smaller than an ambient pressure within the second process compartment and the slit forms, together with the intermediate wall, a vacuum pressure barrier between the first and the second process compartment.

Title: Roller blind winding mechanism - has brake on pulley or cord counteracting torque from blind weight
IPC: A47H3/04
Filed: 1980-12-29
Abstract: The mechanism winds and unwinds a roller blind, having a pulley in a frame engaging with a winding spindle, and in turn engaged by balls on a cord or chain. Brakes are included to prevent the blind unwinding of its own accord. One or more braking devices (13,14,15) act on the pulley (6) and/or the cord (5) with a predetermined pressure, the total braking force thus exerted being greater than the torque from the weight of the blind on the pulley. The device can have a component engaging with a recess in the pulley or between balls on the cord, and thrust free against spring action when torque is applied greater than that resulting from the blind weight.

Title: Low-loss high-speed power switching transistor - has transformer with base-emitter current through primary and rectifier in secondary
IPC: H02M3/155
Filed: 1981-02-16
Abstract: The switching transistor is within a circuit which reduces the loss of power when switching off and also speeds up the switching on process. The transistor has a high inverse voltage as a result of a delay in the change in the base current when switching to the non-conducting mode. The base-emitter current travels through a winding of a transformer and the collector current travels to a different winding of the same transformer. The supply of a bipolar base control voltage is effected via a control transformer (36) with a two-phase rectifier (43,44) on the secondary side. The rectifier output control voltage is fed to the base of the switching transistor (31) via the collector emitter junction of the switching transistor (39).
