Patent CA-2041760-A1 (CA)
Title: Internally assisted clutch
Inventor: FLOTOW RICHARD A
IPC: F16D13/70
Filed: 1991-05-03
Abstract: An internally assisted friction clutch having both engagement springs and assister springs extending between a cover and a release sleeve is disclosed. The radially directed forces exerted by the springs continually center and rotatably drive the release sleeve co-axially relative to the cover under normal operating conditions. In order to prevent excessive relative rotation, a plurality of protrusions are formed on the release sleeve which extend into respective recesses formed on the cover. The recesses are sized to be significantly larger than the protrusions so as to cause engagement only when four to five degrees of relative rotational movement or more occurs between the release sleeve and the cover.

Patent CA-2044302-A1 (CA)
IPC: F01D5/00
Filed: 1991-06-11
Abstract: A method of repairing stator blades in a turbine comprises the steps of making a pre-shaped insert of a material the same as or compatible with the material of the stator blade, the size of the insert is such that it forms a substantial part of the stator blade, the method including the step of removing a piece of material from the stator blade including the damaged part or part that it is required to modify and welding in the new insert. The insert is treated sothat at least a part of it is hardened, the hardening may be diffusion alloying or plasma spray and the size of the insert is that the weld line between the insertand the turbine blade is removed from the area of high wear by making the insertlarger than would apparently appear necessary, this enables substantial cut-outsto be made on each stator blade which in turn permits of much better access to the stator blades for securing the new insert and/or additional hardening steps such as plasma spray after the insert has been secured to the stator blade.

Filed: 1991-06-26
Abstract: Information reading and/or inputting apparatus has a probe, an electrodes, a detector, a position controller and a probe and portion forming device.          By positioning the probe close to an information medium, information reading/inputting is effected in the apparatus.  A voltage is applied to the probe through the electrode.  Information on distance between the electrode and the probe is detected by the detector and whereby the relative position of the probe to the electrode is controlled by the position controller.  The end portion of the probe is reformed in such a manner that a voltage is applied to the end portion of the probe through the electrode under controlling the relative position of the probe to the electrode by the position controller.  A high reliable performance for the apparatus can always be attained by the probe reforming mechanism.

Title: Potable water recovery and fluid preheater for syrup evaporator
Inventor: CAPEN DAVID A
IPC: F28D1/053
Filed: 1991-09-03
Abstract: ABSTRACT     A preheater-condenser for liquid concentrating boiler-evaporators.  A housing which contains a dual manifolded multitubular heat exchanger is fixed to, but removable from, the vertical vent stack of a hooded syrup concentrator-boiler.  The preheater-condenser is an improvement over the state of the art because its vertical positioning, in conjunction with an inclined, ganged and multitubular heat exchanging array, presents a greater heat exchanger surface area to be exposed directly to the boiler exhaust, thus enhancing heat exchange efficiency.  In addition to preheating the liquid which is to be concentrated to syrup, positioning above the hood (and away from the boiling and spattering base fluid) facilitates the use of the tubular array as a condenser by which to accumulate distilled water.          An oblique (inclined) disposition of the tubular array aids the condensation and accumlation process, the latter being acquired in specially compartmented areas of the housing.      During the operation, base fluid is preheated for subsequent introduction to the boiler, while distilled water is drawn off from the accumulation areas.

Abstract: A light bar is provided for mounting to a roof of an emergency vehicle such that the signalling devices comprising the light bar are distributed across the roof to form a non-linear pattern. A dome assembly covers the signalling devices and also forms a non-linear pattern traversing the roof. The light bar provides for enhanced visibility at angles approaching 90° to the heading of the vehicle. Moreover, the non-linear pattern of the signalling devices allows the light bar to provide a signalling pattern whose warning effect can be alternatively directionalized into different distinct zones about the vehicle. In a preferred embodiment, each of the signalling devices is contained in a module comprising a base and a dome such that enhanced transmittance of light is provided at angles approaching 90° from the heading of the vehicle.

IPC: C07K14/415
Filed: 1991-03-14
Abstract: Novel DNA constructs which may be used as molecular probes or inserted into a plant host are provided. These constructs comprise a sequence obtainable from the Bce4 gene that is capable of directing transcription in seed tissue at least as early as 11 days after anthesis until approximately 30-35 days after anthesis, joined to a nucleic acid sequence of interest, and a transcription termination region. Thus, transcription of a message encoded by a nucleic acid sequence under the control of the Bce4 regulatory region will occur at a specific time of seed development. In this manner, production of exogenous products, as well as modulation of endogenous products, may be achieved.
