Patent CA-2027496-A1 (CA)
Inventor: JONES TIMOTHY
IPC: E21B21/08
Filed: 1990-10-12
Abstract: ABSTRACT            METHOD OF QUANTITATIVE ANALYSIS OF DRILLING FLUID PRODUCTS   A method of quantitative analysis of products, such as barite, bentonite or polymers, in a drilling fluid circulating in a wellbore being drilled is described. The method comprises the steps of sampling the drilling fluid, and analysing the sample to determine the density of the fluid and the weight fraction of solids in the fluid. In addition, a known weight of the sample is dried to constant weight so as to obtain the products under the form of solids, which solids are analysed by an infrared spectroscopy technique. The concentration of the products in the drilling fluid is then determined. The method can be applied to the control of the drilling operation by monitoring the quantity of products added to the drilling fluid, such as barite and polymers, or a product coming from the borehole wall or the underground formation being drilled. The invention also applies to the control of the working condition of the mud solids equipment.

Title: Vandal resistant push button assembly
Inventor: MARTIN ADOLF
IPC: H01H13/14
Filed: 1991-08-08
Abstract: A vandal resistant push button assembly has a guide ring attached to a mounting plate spaced from a face plate such as an indicating and announcing device or a modular wall S assembly of an elevator car. The guide ring has a first shoulder which cooperates with a snap ring engaging a first annular groove formed in the guide ring for retaining the ring in an opening formed in the mounting plate. There is play between the periphery of the opening in the mounting .0 plate and the outer diameter of the guide ring such that the guide ring can be aligned with respect to an opening in the face plate and the snap will cover the gap defined by the play. A push button slidably extends through the guide rings on first and second guide surfaces to actuate a switch and a second shoulder formed on the push button engages a stop surface on the guide ring to prevent further travel in the actuation direction. Spring forces originating from the switch press the push button forward to a rest position at which a spring clip engaging a second groove formed in the push button abuts an end of the guide ring. In this position, a seamless spherical surface is formed by the push button and the guide ring at the face plate.

Abstract: An ophthalmological laser surgery system having a laser, associated elements for delivering an optical beam from the user to a patient eye location, a control unit for controlling the operation of the system and a system input/output device, is enabled by a patient data card. The data card originally contains both patient background and system control information, which is transferred to the control unit via the input/output device. During system operation, newly generated information, such as laser beam power, is stored in the data card to provide an independent record of the surgical procedure actually performed. After one use, the data card is invalidated to prevent further use.

Title: Flow regulating valve
Inventor: ZIMMERHACKEL FRANZ
IPC: B65D83/14
Filed: 1992-03-20
Abstract: Abstract A flow regulating valve (22, 23, 24) for a container containing a product which  is  capable  of  flow and which is exposed to a gas pressure, and in a delivery duct a delivery valve (8, 13), so that the product flows out through the delivery duct when the delivery valve is opened,  comprises in  the delivery duct a valve seat  (22)  of hard material and a rubber-elastic regulating member (24) which, when the delivery duct is open, is pressed against the valve seat (22) by the internal pressure in the container.  The regulating member constricts the through-flow cross-section of the delivery duct in the region of at least one throttle duct (23,  24) forming a portion of the delivery duct,  to  a  progressively  lesser  degree  with  decreasing  internal pressure, in order to keep the through flow substantially constant.  In order to be able to maintain closer dimensional tolerances in respect of  the  through-flow cross-section  and  substantially  to  avoid  the through-flow cross-section  being  dependent  on  changes,  caused  by ageing, in the material defining the throttle duct, so that the flow is maintained with a higher degree of accuracy,  the throttle duct is delimited by a groove (23) in the valve seat (22) and the regulating member (24).

Title: Spread-spectrum multiplexed transmission system
Inventor: YERBURY MICHAEL J
IPC: H04J13/00
Filed: 1990-08-31
Abstract: A spread-spectrum transmission system wherein one or more spread-spectrum signals occupy the same frequency band as a group of substantially equally spaced conventional communications channels, the spectral line spacing of the spread-spectrum signals being selected to correspond to the inter-channel spacing of the group of communications channels such that the spectral components of the spread-spectrum signals fall within the inter-channel guard bands of the communications channels. If more than one spread-spectrum channel is used, they are frequency division multiplexed by offsetting the centre or carrier frequencies of the spread-spectrum signals by a fraction of the spectral-line spacing of the signals.  The signals are generated by modulating a carrier with a pseudo-noise (PN) code signal. Demultiplexing is achieved by generating the same PN code in a code generator (47) and mixing the PN code with the received signal in a mixer (45). The epoch of the code generated by the generator (47) is then advanced or retarded in response to an epoch control signal (48) generated by a controller (46). The mixed signal is passed through a narrowband filter (49) to select the baseband signal which is then fed to the controller (46) to enable the generation of the epoch control signal (48).  When applied to a vehicle tracking system, the relationship between the epoch of the noise code and the reference signal (50) is used to indicate the relative propagation delay, when correlation with the received signal is achieved. The delay information, when combined with information from receivers at other locations, can be used to calculate transmitter position.
