Abstract:
A method for manufacturing a multi-density shoe sole is described, the method incorporates repeated injections of sole material onto a shoe upper mounted on a last and placed in a mold. The mold has an injection chamber, moveable side frames, a vertically moveable bottom piston and a shoe sole shaping insert which is placed in the mold prior to a first injection and removed from the mold after said first injection and prior to a second injection. The entire body of the shoe sole shaping insert is placed inside the injection chamber during the first injection. The shoe sole shaping insert acts as a dummy during the first injection, and leaves after its removal a cavity which in a later injection step is filled with another sole material, either another color or another density. Also disclosed is an insert used in a mold for injection molding of shoe soles.

Abstract:
An apparatus for slicing apples is provided. The slicer utilizes thinner blades than known in the art, with a thickness less than 300 microns, and preferably between 180 and 220 microns. Each of the thinner blades is supported against bending, warping or twisting by a novel clinch buckle which rigidly supports the outer end or ends of each blades. The clinch buckle is rigidly connected to bent tabs formed at the outer end or ends of each blade and supports the outer ends across the full width of the blades. The clinch buckle is supported by an outer blade support ring and is captured by the outer support ring to prevent rotation of the clinch buckle. The thinner blade reduces cell damage, reduces the amount of sealant or neutralizer needed to slow or prevent oxidation of enzymes released from cells ruptured by slicing, and delays the onset of browning. A serrated blade is used to further reduce the extent of cell damage.
Abstract:
The invention refers to single-ended test of a loop with the aid of a transceiver, wherein an input impedance (Zin(ƒ)) of the loop is generated. The transceiver has a digital part, a codec and an analog part and is connected to the loop. With the aid of a transmitted and a reflected broadband signal (vin, vout) an echo transfer function Hecho(ƒ)=V(f)out/Vin(f) is generated, which also can be expressed as H echo ( f ) = H ∞ ( f ) Z in ( f ) + Z h0 ( f ) Z in ( f ) + Z hyb ( f ) . Here Zh0(ƒ), Zhyb(ƒ) and H∞(ƒ) are model values for the transceiver. In a calibration process a test transceiver, with the same type of hardware as the transceiver, is connected to known impedances, replacing the loop. Hecho(ƒ)=V(f)out/Vin(f) is generated for the known impedances and the model values are generated and are stored in a memory in the transceiver. The stored model values are then used when the input impedance (Zin(ƒ)) for the loop is generated after a measurement of the broadband signal (Vin, vout) is performed.
Abstract:
The present invention relates to a device for measuring characteristics of an electromagnetic field emitted by a source being tested, comprising a radiating element (8), a support (6) for said radiating element and a mount (5) on which said support is fastened. It is characterized in that it comprises a screen (7) carried by said support (6) and interposed between said radiating element (8) and said mount (5), and in that said screen (7) is adapted to reflect the beams (R1, R2) impinging upon it so as to re-emit and scatter them into space, along determined directions (R′1, R′2). In the measuring device wherein said radiating element (8) is associated with the sighting axis (Δ), so as to point the measuring device (4) along determined measuring directions, said screen (7) can be shaped such that said determined directions (R′1, R′2) include large amplitude angles with said sighting axis (Δ). The measurement site can comprise an anechoid chamber (9) enclosing said source and having walls (90).

The invention is also related to a method for manufacturing a corresponding sole assembly.
Abstract:
The length and attenuation of a signal line between a transmitter and a customer premises equipment is to be estimated. A frequency dependent line input impedance (Zin(f)) as seen from the transmitter, is measured and an absolute impedance value (œ Zin(f) œ) is generated. The latter is shown as a curve (A1) in the diagram with the frequency (f) on the abscissa and the impedance (œ Zin(f) œ) on the ordinate. Extreme values (Max.1, Max2, Max3; Min1, Min2, Min3) arc denoted and a frequency distance (FD1-FD4) between two consecutive of the extreme values is generated. The line length (L) is generated as L=½·vop/FD1, in which vop is the velocity of propagation of a signal on the line. The attenuation is estimated by multiplying the line length with an average attenuation value for the actual line type. The advantages are that the line length can be estimated with good accuracy in a simple manner for short lines and that the line attenuation is estimated in a simple manner.
