Patent CA-2023459-C (CA)
Title: Hydraulic steering unit
Inventor: PEDERSEN POUL H H
IPC: B62D5/093
Filed: 1990-08-16
Granted: 1994-02-22
Abstract: Abstract Disclosure is made of a hydraulic steering unit (1) comprising a housing (2) having a pressure chamber (3) which has an aperture (22) at one end through which a rotatably mounted steering control apparatus is led to the outside and the aperture is sealed from the outside by a sealing ring (9).      With a rise in pressure in the pressure chamber (3) the load on the sealing ring (9) increases and therefore so does the friction between the steering control unit (4) and the sealing ring (9).  This leads to premature wear of the sealing ring. This wear is to be avoided without making the steering unit (1) too expensive.      For this purpose, between the sealing ring (9) and the pressure chamber (3), a one-piece pressure reduction ring (10) is provided to surround the steering control apparatus (4). Between the pressure reduction ring (10) and the sealing ring (9) there is a fluid collecting chamber (11) having an outlet. The pressure reduction ring (10) comprises a circumferential flange-like projection (17) which lies against the end (16) of the pressure chamber (3).

Title: Meat freshness measuring apparatus
Inventor: KANDA MASAHIKO
IPC: G01N33/12
Filed: 1990-09-07
Granted: 1994-10-04
Abstract: ABSTRACT OF THE DISCLOSURE    A meat freshness measuring apparatus measures freshness of meat by detecting changes in a pigment contained in the meat.  For this purpose, the meat (2) is exposed to rays of light of different wavelengths applied from a light source (1), and the rays obtained from the meat are separated to spectra for the respective wavelengths, which are received by a photoelectric conversion element (4).  Spectrum data for each wavelength is amplified and then the amplified data is converted to a digital signal by an A/D converter (7), whereby the digital signal is stored in a RAM (12).  Based on the stored spectrum data and using a prescribed equation of calculation, a content of the pigment in the meat is calculated and outputted by a CPU (10).

Title: Bridge joint construction
Inventor: BENNEYWORTH DOUGLAS F
IPC: E01D19/06
Filed: 1991-02-19
Granted: 1993-09-28
Abstract: ABSTRACT            A method for constructing a bridge joint in a channel (13) overlying an expansion joint (5) involves lining the channel with a thermoplastic asphaltic elastomeric binder (26) followed by successive applications of layers (28, 30) of aggregate and binder mixture wherein the thickness of each layer is restricted to about the maximum dimen-sion of the aggregate in the layer.  Care is taken to insure that both the binder and the aggregate are hot when the layered joint is formed to insure good bonding between layers and with the roadway material.  The aggre-gate of each layer (28, 30) is raked to project upwardly from the mass of the layer before a subsequent layer is applied to enhance the interlock between layers.  A final layer (32) containing smaller aggregate is applied at the joint top and the joint is then sealed and rolled to form an integrated, resilient load bearing structure.

Title: Process for the fine purification of an aqueous alkali chloride solution for use in membrane electrolysis
Inventor: LOHRBERG KARL
IPC: C01D3/14
Filed: 1991-06-13
Granted: 2002-03-26
Abstract: The aqueous alkali chloride solution is coarse-ly purified first. In the succeeding fine purification means the solution, which contains calcium ions, magnesium ions and undissolved magnesium compounds, is passed through a plu-rality of purification stages (ion exchange stages), which contain cation exchange granulate. In the fine purification means the solution having a pH value of about 10 to 11 is passed through a first ion exchange stage and the solution coming from the first ion exchange stage is acidified to de-crease its pH value by at least 0.5. The solution is subse-quently passed through at least one second ion exchange stage and a solution which is virtually free of undissolved mag-nesium compounds is withdrawn from the fine purification means. The acidified solution fed to the second ion exchange stage has preferably a pH value of 5 to 10.

Title: Sonet ds-n desynchronizer
Inventor: REILLY BRIAN F
IPC: H04J3/00
Filed: 1992-10-09
Granted: 1998-07-28
Abstract: A  SONET/DS-N  desynchronizer  and  method  for receiving  an  incoming  stream  of  SONET  (Synchronous Optical  NETwork)   data,  having  a  controller  for controlling either a direct digital synthesis circuit that  provides  a  desynchronized  clock  for  smoothly adapting the rate at which data is retrieved from a data buffer to the rate at which the incoming SONET data is stored in the data buffer.   To minimize jitter and buffer spills (i.e., data overruns or underruns), the frequency and phase  of the desynchronized clock  is constantly varied to match the variations of the data rate of incoming SONET data.  The DDS circuit generates the desynchronized clock, which has a center frequency equal to a predetermined frequency of a reference clock, whose phase is advanced or retarded in accordance with the magnitude of a tuning word supplied by a controller, which implements either a linear, non-linear, or fuzzy logic control algorithm.   The controller periodically updates the tuning word in response to status variables to adjust the frequency of the clock output of the DDS circuit.  In  an  alternative  embodiment,  a  digital voltage controlled oscillator is used in place of the DDS circuit.

Title: Fixed point welding gun
Inventor: ANGEL JEFFREY R
IPC: B23K11/31
Filed: 1993-06-11
Granted: 1996-05-28
Abstract: A resistance welding gun which is adapted to prevent asymmetrical impacting of two or more metal sheets to be welded.  The resistance welding gun includes a pair of rotatably connected arms, each of which has a corresponding working end and actuation end.  An electrode tip is located at each working end to provide a pair of opposed welding electrodes, while a cylinder is attached to the actuation ends of the arms to provide rotation therebetween.  Between the actuation ends there is provided an equalizing mechanism including a crank and a pair of linkages which serve to equalize the movement of the arms about their pivot. In cooperation with the pivot of the arms, the crank establishes a fixed or datum point at which the electrode tips of the resistance welding gun are targeted such that, when properly positioned on opposite sides of the metal sheets, the electrode tips contact the metal sheets substantially simultaneously and apply substantially equal forces to the opposite sides of the metal sheets.  As a result, the equalizing mechanism substantially prevents unilateral contacting and asymmetrical impacting by the electrode tips on the metal sheets.

Abstract: A method for determining the size, shape and position of a pair of upper central incisors for the production of dentures comprises the steps of covering the patient's upper gums with a paste, providing a series of representations of different pairs of upper central incisors and positioning different ones of these representations on the paste until a representation of desired size and shape is selected and secured to the paste by way of an adhesive at a chosen location thereon. The paste carrying the selected representation is then removed from the patient's mouth, whereby dentures can be produced on the basis of the positioning of the upper central incisors on the paste roll and on the selected model of upper central incisors, as the latter determine the models of the remaining teeth of the dentures. The method can also be used for the determination of an artificial tooth used for a dental implant, a bridge or a crown. A kit is also proposed which includes a series of templates providing various representations of two-dimensional pairs of upper central incisors, a paste substance to be applied on the patient's gums or on a denture plate, and an adhesive for securing a selected representation to the substance. Also, a method is proposed for determining the vertical dimension of occlusion with a rest position clearance also for the production of dentures, wherein lower central incisors are positioned with respect to the patient's facial characteristics.
