Patent CA-2016055-A1 (CA)
Inventor: ROTH RUDOLF
IPC: G11B27/19
Filed: 1990-05-04
Abstract: Information-recording system, and recording device and record carrier for use in such an information recording system.      By means of a preformed track modulation (Fig. 1c, Fig. 1d) an auxiliary signal is recorded on a record carrier (1) of an inscribable type in a servo track (4) intended for information recording. The auxiliary signal comprises address codes (AC) and auxiliary codes (HC) which can be distinguished from each other. The address codes specify the address of the track portion in which said codes are recorded, and the auxiliary codes provide additional information about the record carrier, such as references to a track portion having a specific address code.      A recording device (Fig. 8) comprises means (82, 86, 88, 90, 92) for reading the auxiliary signal recorded by means of the track modulation and means (93) for separately detecting the presence of address codes (AC) and the presence of auxiliary codes (HC) in the auxiliary signal.

Title: Aircraft de-icing system
Inventor: SUSKO KENNETH A
IPC: B64F5/00
Filed: 1990-05-30
Abstract: F.9027 AIRCRAFT DE-ICING SYSTEM             ABSTRACT OF THE DISCLOSURE      The invention contemplates preparation of glycol/water de-icing mixtures in a demand-operated system wherein index of refraction and temperature are continuously monitored in a recirculating loop. The supply of heat and changes in mixing proportions of separate flows of water and of glycol are monitored until such time as predetermined values of mixed-fluid temperature and refractive index are achieved. A computer accepts monitoring-signal values for mixed-fluid temperature and refractive index, and further accepts ambient-condition signal values for set-point variation in mixing proportions, as necessary for economical use of glycol in the mixture, under each of a plurality of different ambient conditions.

Title: Split arm throttle cable intervention device
Inventor: PRESTON DAVID M
IPC: B60K31/02
Filed: 1990-06-28
Abstract: ABSTRACT OF THE DISCLOSURE          A vehicle engine throttle valve control device (10) is applied intermediate the vehicle operator's accelerator pedal (14) and the engine's throttle body (12) to selectively override or modify the operator's ability to control vehicle/engine speed and to assert independent control thereof as a function of various input parameters (49,50,52,54).  Linkages (26,28) interconnect opposed ends of an assembly of half levers (21,23) with accelerator and throttle.  The half levers rotate upon a pivot (20) which is selectively displacable to effectively shorten or lengthen the linkage in response to an operator indepen-dent signal from a control circuit (42).  A half lever stop (27) fixes the relative positions of the half levers whenever the throttle body is in an off-idle position.

Title: Sediment collector and separator for drainage systems
Inventor: MANDEL MAX
IPC: B01D21/04
Filed: 1990-08-14
Abstract: Improved Sediment Collector and Separator for Drainage Systems In a drainage system of the type typically employed with domestic sinks and laundry tubs, this invention consists of a transparent container affixed to a drainage system such that the liquid com-ponent of the discharge into the drain will finally exit via the drain system while solid material entering the drain will come to rest in a transparent container. The accumulated material in the transparent container will thereby be observable at will and can thus be removed when deemed necessary. The use of a second sep-arate container utilising a screen in conjunction with this inv-ention will permit the entrapment and easy recovery of valuable objects such as jewellery or contact lenses which may enter the system, without resort to dismantling of the system. Finally, solid material removal from the system may be effected without the use of any tools.

Abstract: ABSTRACT OF THE DISCLOSURE    In a telephone system, a composite detection circuit and method for use in mechanized loop testing to detect both AC ringing and DC coin control voltage at a test access unit.  An equalization circuit distinguishes between the two voltages and selectively amplifies the DC components of the voltages, thus amplifying the positive DC coin control voltages out of the detection range of the negative AC ringing voltages and vice versa.  Two distinct outputs indicate either a positive or negative voltage detected. Two identical circuits are used, one on the ring line and one on the tip line, to detect positive and negative ringing and coin control voltages.

Title: Method and apparatus for improved melt flow during continuous strip casting
Inventor: FOLLSTAEDT DONALD W
IPC: B22D11/06
Filed: 1990-10-02
Abstract: The continuous casting of metal strip using the melt overflow process is improved by controlling the weir conditions in the nozzle to provide a more uniform flow of molten metal across the width of the nozzle and reducing the tendency for freezing of metal along the interface with refractory surfaces. A weir design having a sloped rear wall and tapered sidewalls and critical gap controls beneath the weir has resulted in the drastic reduction in edge tearing and a significant improvement in strip uniformity. The floor of the container vessel is preferably sloped and the gap between the nozzle and the rotating substrate is critically controlled. The resulting flow patterns observed with the improved casting process have reduced thermal gradients in the bath, contained surface slag and eliminated undesirable solidification near the discharge area by increasing the flow rates at those points.

Title: Floppy disk controller with dma verify operations
Inventor: WALDROP TIMOTHY K
IPC: G06F13/28
Filed: 1990-10-23
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention includes two variations of an apparatus which generate a version of the IORC* bus signal that is supplied to the read strobe input of a floppy disk controller that is asserted at the appropriate time during verify cycles between the floppy disk controller and a DMA controller.  These designs allow an 82077 floppy disk controller to operate properly in FIFO mode when it is being used with software that does not require generation of this signal.  The designs include use of a PAL and certain bus signal inputs to generate a signal which is asserted at the appropriate times during verify transfers. This signal is combined with the regular IORC* bus signal to produce the signal that is provided to the read strobe input of the floppy disk controller.

IPC: H01B13/00
Filed: 1991-04-05
Abstract: In a simple and inexpensive method of manufacturing a composite electric and optical cable incorporating a flexible tube having a flexible optical waveguide loosely housed in the bore of the tube, the flexible electric cable, without a flexible optical guide loosely housed in the bore of the flexible tube, is wound around the hub of a cable drum in such a way that each end of the wound cable is exposed and accessible.  The flexible optical guide is then accommodated in the bore of the flexible tube of the wound cable by introducing a leading end of the optical guide into the end of the bore of the flexible tube at one exposed end of the wound cable and by propelling the optical guide along the bore of the wound cable by fluid drag of a gaseous medium which is passed through the bore in the desired direction of advance at such a pressure that the optical guide is carried along the bore until the optical guide is loosely housed in and throughout the length of the bore of the flexible tube of the wound cable.
