Abstract: On a gas-turbine engine, in particular an aircraft engine, with a fan, a fan casing and a fan duct as well as with high-pressure and low-pressure turbines arranged behind each other in flow direction in the casing of the engine, the auxiliaries connected are to be operated with only a small increase in engine power. For this purpose in the flow direction of the airflow (20) exiting from the high-pressure turbine (15) a bleeding mechanism is provided for bleeding radially into the fan duct (4) at least part of the airflow (20) leaving the high-pressure turbine (15) on the upstream side of the low-pressure turbine (16).

Abstract: A method for curing a resin contained in a liner of an underground pipe or passageway by use of a mobile magnetron module. The module navigates the length of the passageway of pipe via air pressure which also keeps the liner inflated. A winch attached to the module regulates the rate at which the module traverses the passageway or pipe. As the module makes its way through the passageway or pipe, the magnetron emits microwaves which cures the resin. Additionally, a thermal imaging camera can be utilized in the module or trailing the module to monitor the status of the curing of the resin in its entirety.

Abstract: A method for checking the condition of containers (2) comprising a hollow body (5) for containing a semi-liquid or semi-solid product and a membrane (6) for closing the hollow body (5) comprises the steps of: closing the container (2) inside a test head (4) comprising a housing (10) to hold the container (2) and a cap (11) hermetically sealing the container (2) and defining an empty internal space (15); pressurizing the space (15) inside the cap (11) by introduction of pressurized air inside the space (15), for a defined period of time (Ta); releasing the pressurized air from the space (15); measuring the movement of the membrane (6) due to the pressurization of the space (15), by means of a position sensor (14); depressurizing the space (15); measuring the movement of the membrane (6) due to the depressurization of the space (15), using the position sensor (14).

Abstract: A packaging arrangement is provided for displaying a tool set and a plurality of interchangeable work pieces at a point of sale that is useable as a carrying case after it is purchased. The packaging arrangement has an insert with a plurality of receptacles at spaced apart intervals between the outer ends for individual reception of the interchangeable work pieces. A locking member is provided with the insert and is moveable between an engaged position and a disengaged position to selectively secure the interchangeable work pieces in the receptacles of the insert.

Abstract: A gas-turbine exhaust cone includes a cone shaped outside cone 1 closed in a flow direction, an inside cone 2 arranged in the outside cone 1 over at least part of the length of the exhaust cone, with the inside cone 2 being connected to the outside cone 1 via at least one helical partition wall 3, thereby forming an interspace 4 between the outside cone 1 and the inside cone 2. The interspace 4 is connected to inlet openings 5 at its inflow side and opens at an exit side 6 towards an interior 7 of the outside cone 1. A dampening element 8 is arranged in the outside cone 1 adjacent to the exit side 6 of the interspace 4.

Abstract: A nozzle includes first guiding elements (10) circumferentially arranged at a nozzle rim (9). To reduce sound emission while keeping flow losses low, second guiding elements (20) are also circumferentially arranged at the nozzle rim (9), with one of the first and second guiding elements (10, 20) being diffuser-type and the other of the first and second guiding elements (10, 20) being nozzle-type and with both types of guiding elements circumferentially alternating with each other.

Abstract: In an axial fan (1), equipped with a frame (13), a motor (2) and an impeller (3) whose hub (15) is rotationally driven by the motor (2) and where the hub (15) is cup-shaped, with an end wall (16) and an annular side wall (17) to partially contain the motor (2), the motor (2) protrudes from the hub (15) with its longitudinal end (23) which is supported and laterally surrounded by a crown (12) of the frame (13) and the crown (12) has an annular end strip (21) facing the hub (15) and laterally surrounding an annular end strip (22) of the hub (15) which faces the crown (12).

Abstract: Pouches (2) of cohesionless material, typically a smokeless tobacco product, are manufactured on a machine equipped with feed components (101) by which the material is supplied to a conveyor (4) at a delivery station (8), then transferred by the conveyor (4) from this station (8) to a transfer station (9) where a forcing mechanism (14) directs measured portions (100) of the material from the conveyor into at least one duct (12) connecting with a form-fill-and-seal wrapping station (10) where the portions (100) are enclosed in a continuous succession (21) of pouches (2). Before being separated one from the next at a downstream cutting station (23), the single pouches (2) pass through an in-line quality control station (105) at which their weight is checked individually.

Abstract: A machine for producing ice cream shop products comprises a whipping and freezing unit (2) with a horizontal axis (A) and a removable head (10) forming an end wall (11) of the whipping and freezing unit (2), there being in the wall (11) an inlet (12) for ingredients intended to constitute the ice cream shop products, and an outlet (13) for the ice cream shop product prepared.
