Abstract: The invention relates to an automatic device for placing and prescrewing of caps on gas cylinders. 
     In accordance with the invention, the device has a rotatable support (101) carrying at least one gripping head (104) movable in rotation about a vertical axis and in parallel translation to that axis. Said support can be moved to take each head alternately to a cap gripping station or to a placing and prescrewing station for said caps; and the or each rotating gripping head (104) is equipped with mobile gripping fingers (106) and a central telescopic spindle whose lower end extends into a centering cone (123) for engaging the wheel (5) of the gas cylinder valve for perfect centering of the cap to be prescrewed on the axis of the collar, and whose upper end contacts a damping device (124) serving to limit the axial forces to which the external thread of the collar is subjected during prescrewing. 
     Application to the automated handling of screw caps on gas cylinders, in particular LPG cylinders.

Abstract: A clip for fastening a railway rail to a rail foundation is proposed, which clip is made of a rod of resilient material such that it has at least one bent portion of which the axial cross-sectional area is greater than that of the remainder of the clip. In one embodiment of the clip, the clip comprises, proceeding along the rod from one end thereof to the other, a first portion (1) which is substantially straight, the said one end of the rod constituting a free end (1b) of the said first portion (1), a second portion (2) which is a reverse bend, a third portion (3), a fourth portion (4) which is another reverse bend, and a fifth portion (5), the construction of the clip being such that it can be placed in a position in which a longitudinal axis of the first portion (1) extends horizontally and the third and fifth portions (3, 5), when viewed from above, appear to lie on opposite sides of the said first portion (1), wherein the axial cross-section of more than a tenth of the length of the said first portion (1) of the clip is smaller in area than the axial cross-section of at least a region of the said second portion (2) of the clip. Such clips may be made of less material as compared with some prior art clips intended for the same purpose, thereby being cheaper to make.

Abstract: A chair tilting mechanism (1) is disclosed which has a fixed support (2), a seat support (3) and a backrest support (4). The seat support (3) is pivotally connected to the fixed support (2) by a pivot pin (5). The backrest support (4) is pivotally connected to the seat support (3) by a pivot pin (6). There is additionally provided a link (7) connected by pivot pins (8,9) to the backrest support (4) and the seat support (2). Because of the link (7), rotation of either the backrest or seat support causes the other of the backrest or seat support to tilt in a pre-determined synchronised manner. The manner in which synchronised tilting occurs is set by the interconnection of the various parts. The invention also provides a means (41) for pre-setting the interconnection.

IPC: H03L7/085
Filed: 1992-07-01
Abstract: A phase error processor (130) interfaces a proportionate phase detector (120) to a digital loop filter (140) in a high frequency phase-locked loop (PLL). The PLL receives a high frequency stream of NRZI encoded data, which contains a variable density of data signal transitions. A phase detector in the PLL generates proportionate phase error information in the form of a phase error pulse signal PD1 and a reference pulse signal PD2 for each data transition in the incoming data signal. The phase error processor, using a "decimation" technique, integrates the proportionate phase error information from just one pair of adjacent positive and negative data transitions during each period of N clock cycles if the number of input data transitions which occur during that time period exceeds the expected minimum, otherwise the phase error processor passes no phase error information. The selection of window width is based on the coding scheme of the incoming data stream. The integrated information is converted by the phase error processor once during each N-clock cycle period into a one-bit Up/Down signal that is then used to either advance or retard the output phase of the PLL's digitally controlled oscillator. The phase error processor also detects when the density of edges in the incoming data stream falls below a minimum allowed level, and generates a "data valid" signal indicating whether the Up/Down signal is valid.

IPC: F02C7/28

Abstract: A labyrinth seal (10) for a gas turbine engine of the type having a high pressure compressor and high pressure turbine, an outer shaft (12) interconnecting the high pressure compressor and turbine, a low pressure compressor and turbine, and an inner shaft (14) interconnecting the low pressure compressor and turbine wherein the shafts are concentric and are separated by the seal. The labyrinth seal includes a cylindrical sleeve (34) which is discrete from and attached to the outer shaft, and which includes a plurality of annular seal teeth (36) extending radially inwardly to the inner shaft. By placing the seal teeth on a sleeve which is discrete from the outer shaft and is easily replaceable, stress cracks created in the region of the seal teeth are prevented from propagating to the outer shaft and maintenance of the shafts is facilitated. Further, by configuring the seal teeth to extend radially inwardly between two relatively rotating components, the fluid trapped by the seal is forced to take a tortuous path along the inner shaft; as a result, the seal of the present invention is more efficient at high temperatures and rotational speeds. The sleeve is captured between an annular rabbet (44) at an aft end and radial slots formed on a seal tube the latter of which engage spaced, axially-extending fingers (48) on the sleeve at the forward end of the sleeve. The sleeve is at a relatively low radius where mechanical deflections due to centrifugal loads of the two concentric shafts are similar. Deflection of the seal teeth is away from the inner shaft due to thermal effects in the concentric shafts.

Abstract: A high angle light scattering detector using classical Rayleigh scattering. A high intensity arc light source, filtered to leave only one wavelength illuminates a flow cell. Through the flow cell, very small particles such as biological proteins flow in solution after separation by HPLC or some other means. A UV detector generates data regarding the weight concentration of the eluting particles and a scattered light detector collecting scattered light at angles of approximately 90 DEG  generates a scattered light signal. The incident light intensity is also measured. The average molecular weight is then computed using the scattered and incident light data the weight concentration data and a simplified mathematical relationship from which the size factor P and the viral coefficients have been eliminated.
