Abstract: A microwave power amplifier arrangement for an electron paramagnetic resonance (EPR) system provides amplified microwave pulses having a microwave frequency in the X-band. The arrangement has a microwave input and a microwave output, and comprises at least one transistor amplifier device, and at least one switchable reflection device. A respective transistor amplifier device comprises a transistor amplifier device input directly or indirectly connected to the microwave input (2), at least one transistor, and a transistor amplifier device output directly or indirectly connected to the microwave output. A respective switchable reflection device comprises a PIN diode and a lambda/4 line connected directly or indirectly to the transistor amplifier device output of at least one transistor amplifier device and to a first port of the PIN diode, with lambda being the wavelength of the microwave radiation within the lambda/4 line. A second port of the PIN diode is connected to ground.

Abstract: A method for computing a Miller-factor compensated for peak noise provided. The method includes mapping at least two delays as function of at least two Miller-factors; determining an equation of the function; computing a peak noise; computing a peak delay resulting from the peak noise; and computing the compensated Miller-factor based on the equation and the peak delay. The function can be either a linear function or a non-linear function.

Abstract: Multiple myeloma is treated by deletion mutants of the gp130 protein of the IL-3 receptor. These mutants inhibit the binding of Hck tyrosine kinase and the growth of tumor cells, particularly myeloma cells.

Abstract: The invention relates to a shoe having an arch support extending from an interior of a shoe to an exterior of a shoe. The arch support can be adjusted from the exterior of the shoe. The arch support includes straps which each have a slide groove formed therein. On one end of each strap are strap eyelets. The shoe includes an upper having a slit opening separating an upper paneling and a lower paneling. The arch support is located within the shoe, and extends through the slit opening. Rivets connect the upper paneling and the lower paneling. The rivets are also aligned with and extend through the slide grooves on the arch support. Accordingly, the arch support straps may slide along the rivets to tighten or loosen the arch support within the shoe.

Abstract: Shoe (1), especially an athletic shoe, with a midsole (2) and an upper (3) connected to the midsole (2), the midsole (2) having a base body (2a) which is connected to the upper (3), and a bottom plate (2b). To improve the adjustability of the spring properties and/or the damping properties of the shoe sole, it is provided that at least one part (4, 5) of the bottom plate (2b) is connected to the base body (2a) by a hinge at an articulation point (7). Furthermore, at least one spring element (8) is provided between the side of the part (4, 5) of the bottom plate (2b) facing the base body (2a) and the side of the base body (2a) facing the part (4, 5) of the bottom plate (2b). Preferably, one spring is provided in the heel area and a plurality of springs are provided in the forefoot area.

Abstract: The present invention describes a means for the treatment of multiple myeloma. Deletion mutants of the gp130 protein of the IL-3 receptor are presented which inhibit the binding of Hck tyrosine kinase and the growth of tumor cells, particularly of myeloma cells.

Abstract: A butterfly damper for installation in duct work through which air and/or gases will be flowing either under a positive or negative pressure has: an outer cylindrical surface structure made of a strong material; an inner cylindrical surface structure made of a resilient material; a circumferential portion of compressible material, which is always tending to return to the non-compressed form thereof, which is initially compressed between the outer cylindrical surface structure and the inner cylindrical surface structure, whereby the inside diameter of the duct body portion, initially, is uniform throughout the length thereof, and, thereafter, when the initial compressive force becomes less effective, the compressive material expands causing radially inward movement of adjacent circumferential portions of the inner cylindrical surface structure; a blade to be moved across the flow of air and/or gases into sealing contact with the radially inwardly moved circumferential portions of the inner cylindrical surface

Abstract: A butterfly damper for installation in duct work through which air and/or gases will be flowing either under a positive or negative pressure has: an outer cylindrical surface structure made of a fixed strong material; an inner flexible cylindrical surface structure made of a resilient material; a circumferential portion of compressible material, which is always tending to return to the non-compressed form thereof, which is initially compressed between the outer cylindrical surface structure and the inner cylindrical surface structure, whereby the inside diameter of the duct body portion, initially, is uniform throughout the length thereof, and, thereafter, when the initial compressive force becomes less effective, the compressive material expands causing radially inward movement of adjacent circumferential portions of the inner flexible cylindrical surface structure; a blade to be moved across the flow of air and/or gases into sealing contact with the radially inwardly moved circumferential portions of the in

Abstract: An apparatus that projects the horizontal and vertical axis of an object to be aligned for ready sighting by survey instruments is disclosed. The device consists of a v-frame with a rotatable head to which a target platform for mounting a vertical or horizontal scale may be affixed. The v-frame is held on the object and moved about the object until the surveyor can see the target scale without having to remove ancillary equipment that would ordinarily obscure the target. Standard surveying methods may then be used to align the object.

Abstract: A disk-shaped plastic shield adapted to rest against the palm of the hand of the hair cutter adjacent to a knuckle to prevent scissor cuts when trimming hair, and a finger guard.

Abstract: A helical band to be positioned around the second knuckle of the middle finger of the barber's hand which is not used to operate scissors. The band is used when cutting the ends of hair gripped between the index finger and the middle finger and prevents the scissors from cutting the flesh around the second knuckle.
