Patent CA-2103746-A1 (CA)
Inventor: OBERMEIER MANFRED
IPC: D07B3/00
Filed: 1993-08-10
Abstract: A device for the alternating stranding of stranding elements (1), which consists of a stationary guide disc (3) and of a stranding disc (5) arranged at a distance from the latter and rotatable about its axis, is specified. The two discs have axially extending passage holes (13) for leading through the stranding elements (1). The device also includes a fixed point (6) for fixing the stranded stranding elements (1) at the stranding point. For the perfect guidance of the stranding elements (1), there is arranged between a guide disc (3) and stranding disc (5) at least one thread-like, tension-resistant carrying element (12), on which is mounted at a distance from the guide disc (3) on the one hand and from the stranding disc (5) on the other hand at least one holding element (11) which has axially extending passage holes (13) for leading through the stranding elements (1). <IMAGE>

Title: Differential driver/receiver circuit
Inventor: WADE JON P
IPC: H03K17/16
Filed: 1992-03-27
Abstract: A new driver circuit and receiver circuit for transmitting and receiving a differential signal pair. The driver circuit includes true and complement signal generating elements that generate a differential signal pair in tandem. Each of the true and complement signal generating elements includes a high-gain element and at least one low-gain element. The delay circuit is responsive to the true and complement data signal for iteratively controlling the high-gain element and low-gain element of each signal generating element to effect the generation of the differential signal pair, the delay circuit controlling the high-gain element with a delay relative to the low-gain element to thereby reduce ringing in the differential signal pair. The receiver circuit receives a differential receive signal pair, comprising true and complement receive signals having selected conditions over a pair of input lines and generates a true and complement data signal. The receiver circuit, during normal receiving operations, generates true and complement signals in response to the differential receive signal pair. During a test mode, the receiver circuit, in separate steps, compares the voltage levels of the true and complement receive signals to threshold voltages and generates an error signal if the selected true or complement receive signal does not have the proper relationship to the voltage level of the threshold voltage.

Abstract: An improved device and method of a) separating the cellular components of whole blood from plasma or serum, b) separating the low density lipoprotein (LDL) fraction and the very low density lipoprotein (VLDL) fraction from the plasma or serum, then c) assaying the plasma or serum for cholesterol present in the high density lipoprotein (HDL) fraction are disclosed. The device includes a separation area that separates the cellular components of whole blood from the serum or plasma and separates the LDL and VLDL fractions from the serum or plasma, and a test area that assays the serum or plasma for the concentration of the HDL cholesterol. The method includes introducing a whole blood sample to a test device including a separation area comprising a first zone that separates the cellular components of the whole blood from the plasma or serum; and a second zone that separates the LDL and the VLDL fractions from the plasma or serum. The essentially cell-free, LDL-free and VLDL-free plasma or serum then migrates to a test area. After the plasma or serum migrates to the test area, plasma or serum is assayed for HDL cholesterol and the test area is examined for a quantitative response to HDL cholesterol present in the whole blood sample.

Title: Increased efficiency method and apparatus for lining a pipe with a cement mortar
Inventor: PERKINS ALFRED G
IPC: F16L55/1645
Filed: 1994-09-15
Abstract: Abstract of the Disclosure An increased efficiency method and apparatus for lining a section of pipe with a cement mortar.  After a wet cement mortar has been applied to a cleaned interior surface of a pipe, carbon dioxide is introduced into the freshly lined section of the pipe in such quantity that a crust of calcium carbonate will be formed on the interior surface of the wet cement mortar lining as the carbon dioxide reacts with calcium compounds of the wet cement mortar in a relatively short period of time.  This crust is provided to protect the underlying mortar from scouring, while tolerating a low-velocity flow of water, until the normal hardening of the underlying mortar through hydration can take place so as to substantially reduce the out-of-service time of the section of pipe which is being lined.  In order to provide a saturated carbon dioxide gas condition within the water main section for effective and rapid formation of the crust but with a minimum waste of carbon dioxide gas, the carbon dioxide gas pressure is regulated to maintain a positive pressure just slightly greater than atmospheric, bellows preferably provided to precisely indicate pressure.

Abstract: A data center provides a rate table to a user.  The rate table is communicated to the mailer along with a hash code.  The hash code is based on information from the rating table.  The hash code provides a unique number based on the rating table provided.  The algorithm within a secure device and to which the rate table is loaded regenerates the hash code based on the information received from the rate table and compares the transmitted hash code with the generated hash code.  A comparison is made of the received hash code and the generated hash code to verify that the rate table data has not been intentionally or unintentionally corrupted.  The transmitted hash code may be encrypted by the data center and when received decrypted by the mailer. The encryption decryption process establishes authenticity of the data center if desired.     The generation of a hash code based on the stored rate table and a comparison with a stored hash code previously transmitted can be initiated prior to postage printing and used to insure proper rating.  Printing is enabled only after the rating process has been properly implemented.  The hash code and rating information may be printed on the mail piece such that a verifying party can reconstruct the rating process and determine if rating inaccuracy occurred. Various rating inaccuracy for a particular user can be stored by the verifying party to detect a recurrence of rating errors.  Rating profiles for particular users or group of users may be stored to enable generation of user profiles.
