Title: Rotational vibration damper, particularly for motor vehicle transmissions
IPC: F16F15/12
Filed: 1987-06-04
Abstract: 1. Rotational vibration damper having a cup (1) which can be flanged onto a shaft and a ring (2) which is elastically coupled to the circumference of the cup via at least three rubber webs (3), which ring is provided on its side facing the cup with at least two stops (5, 6) which interact with a radially protruding projection (4) on the circumference of the cup (1) such that the magnitudes of the pendular movements of the ring (2) around the cup (1) are restricted in both directions of rotation, the stops (5, 6) and/or the projection (4) consisting of an elastomer material. 2. In the case of known rotational vibration dampers of this type, in the event of large amplitudes, the material damping is inadequate to achieve sufficient vibration damping. 2.2 In order to achieve satisfactory damping not only for small vibration amplitudes but also for large amplitudes of the rotational vibration to be damped, without increasing the material damping and without changing the inertial mass, friction surfaces (7 and 8) are arranged on both sides of the projection (4), running in the circumferential direction, which friction surfaces (7 and 8) interact with external surfaces (9) of the stops (5, 6) running in the circumferential direction. The same effect is achieved when friction surfaces running in the circumferential direction are arranged on the sides of the stops facing the projection, which friction surfaces interact with the external surface of the projection running in the circumferential direction. 2.3 The rotational vibration damper is particularly suitable for motor vehicle transmissions. <IMAGE>

Patent EP-0265805-A3 (EP)
IPC: H01L21/18
Filed: 1987-10-17
Abstract: An apparatus for measuring the diameter of a crystal in 
which an optical sensor scans along a sensing line which 
crosses at one point a luminous ring formed at the 
interface between a crystalline rod and a melt; the picture 
element position corresponding to a maximum luminance is 
discriminated when the optical sensor scans; the mean value 
of the picture element position is calculated over at least 
one revolution of the crystalline rod; and the diameter D 
of the crystalline rod at a portion thereof interfacing 
with the melt is calculated from the mean value and the 
level of the melt. Similarly, the minimum crystal diameter 
can be calculated by obtaining the picture element position 
corresponding to the minimum crystal diameter instead of 
obtaining the mean of the picture element position.

Abstract: The transmission of digital signals consisting of data blocks, each 
delimited by one among several possible words (DDi) and enumerated in 
transmission by enumeration reconstuctable in reception even in 
presence of errors, includes the transmission of a pseudo-random 
sequence, that asummes e.g. values of 0 or 1, which values are 
correlated with two data block delimiting words named respectively DDO 
and DD1. The reception side forms two pseudo-random sequences, one of 
which being supplied by a local generated and identical to the 
transmission sequence, the other sequence being reconstructed according 
to the revealed data delimiting words. The comparison between the two 
pseudo-random sequences otained in this manner in reception allows, 
after having made an initial synchronization operation, to verify the 
correct interpretation of the received data blocks delimiting words and, 
in case of interpretation errors, to apply suitable resynchronization 
actions for recovering the correct enumeration of received data blocks.

lines (BL1, BL2; BL1′, BL2′)associated with a common 
sense amplifier (10). One of each of the bit line 
pairs is multiplexed into the sense amplifier and the 
other unselected bit line pair is clamped to AC ground

Title: Nucleic acid probe for the detection of salmonella human pathogens
IPC: C12Q1/689
Filed: 1990-02-12
Abstract: Described herein are nucleic acid probes that can detect Salmonella human pathogens. The probes are generated from the nucleotide sequences of a gene encoding a virulence factor involved in the pathogenesis of Salmonella, especially the Type 1 fimbriae protein. The most preferred lengths of the probes range from about 20 to about 100 nucleotide bases in length. The probes are highly specific and sensitive for detecting Salmonella organisms pathogenic to humans. They are thus clinically useful in the detection of infection in diarrhea specimens. Additionally, they may be used in the detection of food-borne Salmonella, the causative agent of most salmonellosis in humans.
