Abstract: The invention concerns the field of packaging solid but fragile products. 
<??>One of its advantages is that it allows a very good application of robotics to the packaging process and another advantage is that of considerably reducing storage volumes. For these purposes, the bolster is manufactured in a continuous form and only its desired length (8) is extracted in such a way that the rest of the bolster remains in a container (9) where it is held compressed before its use. 
<??>During packaging, the product (15) to be packaged is disposed by gravity in a groove (8a) of the bolster (8) and the assembly is inserted into a case (13). The bolster (8) folds on itself and more or less completely surrounds the product (15) along the envisaged bolster length.

Inventor: OKADA KENICHI
IPC: G01C19/72
Filed: 1990-03-21
Abstract: A modulated phase difference is detected between two rays of light phase modulated by a phase modulator (24), having propagated through an optical fiber coil (17) in opposite directions and interfering with each other. A ramp voltage (Rp) controlled in polarity and frequency in accordance with the detected phase difference is generated. The ramp voltage (Rp) is applied to the phase modulator (24) to control it so that a maximum phase shift of light thereby is 2π k rad (where k = ± 1 ± 2, ...). To correct the temperature characteristic of the phase modulator, a peak value control circuit (60) creates a reference voltage corrected by a voltage detected by a temperature sensor (50) and controls the peak value of the ramp voltage by the reference voltage, thereby ensuring that the maximum phase shift of light in the phase modulator (24) is always 2π k rad regardless of temperature changes.

Abstract: In a method for calculating the flow velocity of, for example a blood stream, ultrasound pulses are repeatedly transmitted into an examination region with a spacing of a pulse repetition time (Tr). An autocorrelation function (Kii) and a cross correlation function (Kiq) in an environment (Tr+/-1.5 T) around the pulse repetition time (Tr) are formed from the quadrature components (i, q) of echo signals of respectively successive transmission pulses. The shift of the maximum ( DELTA t) of the correlation functions (Kii, Iiq) relative to the pulse repetition time (Tr) as a result of the velocity of the flow is fixed in a region (Bn) wherein the ambiguous, mean Doppler frequency ( omega ) identified in a traditional way lies. The apparatus for the implementation of this method comprises a shift identification circuit for this purpose. This shift identification circuit calculates the shift of the maximum ( DELTA t) of one or both correlation functions (Kii, Kiq) relative to the pulse repetition time (Tr).

Title: Device and procedure to determine and regulate the number of drops passing a drip chamber
IPC: A61M5/168
Filed: 1990-05-18
Abstract: A number of devices are known in the prior art for determining the number of drops passing through a drip chamber. However, one disadvantage of these devices which has been noted is that the desired drop rate cannot always be maintained and must be corrected manually by the operating personnel. The device according to the invention provides a remedy to this problem, by means of a control mechanism with a housing (3), which has in a vertical direction a bore (13) with a widened recess (7), into which, in the use state, the roller clamp housing (4) with roller clamp wheel (5) is introduced, while the tube (6) is held by the bore, and the roller clamp wheel (5) being held, at its part projecting out of the housing slot (16), approximately positively by a guide segment (11) which can be moved up and down vertically in the housing (3) and which is connected to a drive (10), and the control mechanism having a keyboard (14) for setting the drop rate or intended drop number/time unit and an electrical cable (15) with which it is connected to the drop counter (2), and the intended drop number/time unit being stored in a microprocessor which is contained in the control mechanism (3) and which, in the event of a deviation with respect to the actual drop number shown on the display (12), activates the drive, which leads to a vertical upward or downward movement and, consequently, to a reduction or increase in the drop rate or the liquid quantity to be applied/time unit, and to the compensation of desired and actual values of the drop number. <IMAGE>
