Patent CA-2235570-A1 (CA)
Title: Cavitation-free gear pump
Inventor: MCMILLAN WILLIAM D
IPC: F04C2/20
Filed: 1998-04-22
Abstract: A positive displacement gear pump useful for pumping hydraulic fluid includes a drive gear and an idler gear. In a first embodiment, the drive gear has symmetrical teeth, whereas the idler gear has asymmetrical teeth. The asymmetrical teeth of the idler gear include working surfaces which have a profile corresponding to the profile of the working and non-working surfaces of the drive gear, but have a non-working surface which has been relieved so as to be substantially flat. Consequently, in the zone of the pump where the gears mesh, a large backlash is created which substantially prevents bubble formation. In a second embodiment, the drive gear, as well as the idler gear, have non-contact surfaces which are substantially flat to create even a larger backlash for relieving cavitation when the teeth are made wider in the axial direction. By preventing bubble formation, cavitation which occurs at high pump speeds is substantially eliminated, thus avoiding pump damage which results from cavitation.

Abstract: Method of systematically deforming a plane mirror to function as a focusing heliostat of adjustable focal length. A plane mirror is made to deform through the application of force at a number of peripheral points which is opposed by the application of force to the centre area of the mirror. The resulting complex topology functions as a solar mirror capable of concentrating incident sunlight on a distant focal point. By adjusting the degree and location of the forces applied to the mirror, the focal length and degree of concentration of sunlight on the focal point can be adjusted.

Abstract: A method to determine an access frequency band in a communication access network. The communication access network includes terminals (T11, T12, T13, ..., T31, ...) and a head-end (HE) which includes transceivers (TRX1, TRX2, TRX3, ...). The head-end is downstream coupled to each one of the terminals via a downstream common link (Lc) and a tree-like distributive network. Each one of the transceivers provides to a combiner (COMB) included in the head-end a downstream signal (Sd1, Sd2, Sd3, ...) in a frequency band associated by means of a predetermined first association to one of the transceivers. The downstream signals are together combined by the combiner into a downstream modulated signal (S-MOD). The downstream modulated signal is broadcasted from the head-end to the terminals. A first one (T12) of the terminals is upstream coupled to at least one receiving transceiver (TRXrec1, TRXrec2, ... ) which is one of the transceivers, via a common upstream link and at least one upstream sublink. The access frequency band is one of the frequency bands (CH1, CH2, CH3, ...) to be used by the first terminal (T12) to filter out of the downstream modulated signal one of the downstream signals provided by an access transceiver which is one of the transceivers in order to establish a communication between the access transceiver and the first terminal.The method includes the steps of: a) choosing by the first terminal out of the frequency bands a start frequency band (CHst); and b) determining by the first terminal with the start frequency band and according to a predetermined second association an upstream frequency band (CHu). The upstream frequency band is one of the upstream frequency bands whereof each one is associated by means of the predetermined second association to one of the frequency bands; and c) transmitting by the first terminal within the upstream frequency band an access request signal (AR(T12)) to the receiving transceivers; and d) filtering by the receiving transceivers out of incoming signals which includes the access request signal within a predetermined upstream frequency bands according to the predetermined first association and the predetermined second association and thereby providing a filtered signal; and e) in the event that the upstream frequency band substantially equals to one of the upstream frequency bands used by a first (TRXrec1) receiving transceiver in the step d) whereby the filtered signal substantially equals to the access request signal, confirming to the first terminal by the head-end (HE) that the start frequency band constitutes the access frequency band; f) in the event that after a predetermined time from sending the access request signal without receiving of the confirmation of the step e), repeating the steps of the method with another start frequency band (CHst').

Filed: 1997-06-25
Abstract: The mechanical lock of the present invention has an elongated housing (14). A  pair of end bushings (40 and 42) mounts in the housing, and a rod (30) translates through the end bushings and at least partially through the housing. A pair of coiled locking springs (60 and 62) within the housing are around the rod and between the end bushings.  One end of each locking spring is fixed within the housing, and the other end of each locking spring is free. The normal inside diameter of each locking spring is less than the outside diameter of the rod so that the locking springs secure the rod. A handle (78) can uncoil the free end of each locking spring to increase their inside diameter and release the rod. A wedge bushing (100) mounts in the housing between the locking springs. The face on each end bushing against its respective locking spring is at an angle, and the wedge bushing also has an angled face on the other side of each spring. Therefore, when the rod (30) and housing (14) are loaded with respect to each other, the angled face of one bushing cants one locking spring, and an angled face of the wedge bushing cants the other lacking spring.
