Filed: 1990-07-19
Abstract: Un sida-car pour motocyclette, caractérisé en ce que la caisse du sida-car surplombe la roue du sida-car directement au-dessus de celle-ci. Le raccord d'accouplement latéral du sida-car à la moto contraint la roue du sida-car à s'incliner à l'intérieur d'une courbe, avec les roues de la moto, lorsque le véhicule en mouvement emprunte une courbe sur une route. Le cadre et la caisse du sida-car s'inclinent avec la roue, de sorte que le centre de gravité du sida-car demeure continuellement dans le plan de sa roue. Au dur et à mesure que les roues de la moto s'inclinent, leur valeur angulaire A par rapport à la verticale augmentera par rapport à la valeur angulaire a représentant l'inclinaison de la roue du sida-car par rapport à la verticale.

The phase converter embodies an induction machine acting as rotary phase-shifter (4) and a compensation circuit (5) containing passive elements only.  Another version with additional features for improved efficiency is also shown. Moreover this phase converter can also be connected to a triphase power source to supply a single-phase load because of the current symmetry avaiable.

Title: Method of protecting casing during high pressure well stimulation
Inventor: JENNINGS ALFRED R JR
IPC: E21B17/00
Filed: 1991-08-14
Abstract: ABSTRACT    A method of protecting casing during high pressure well stimulation.  An annulus between the casing and tubing is loaded with water via a small volume of nitrogen to partially displace annular fluid down the annulus and up the tubing. This loading takes place prior to setting a packer.  Loading in this manner results in a gas "cushion".  If the tubing should burst during high pressure stimulation, compression of the "cushion" will prevent the casing from rupturing.

Inventor: ASLIN DAVID J
IPC: G01F3/10
Filed: 1991-11-29
Abstract: A liquid dispensing system utilizes a microprocessor based electronic control and a positive displacement gear pump to accurately meter predetermined batches of liquid from a supply tank.  The gear pump is driven by a reversible motor through a gear reducer, and is operative to pump a predetermined fixed volume of liquid for each revolution or fraction of revolution of the pump drive shaft.  A passive magnetic sensor is positioned adjacent the toothed periphery of a target wheel, which is mounted on the motor shaft, and generates a signal representative of the amount of rotation of the pump drive shaft.  The electronic control is responsive to this signal for calculating the total volume of liquid displaced by the pump.  The electronic control includes a keyboard which enables a user to preprogram the precise amount of liquid to be dispensed.  The system includes a discharge hose for dispensing the liquid into a user's container, which hose is automatically primed by the system prior to the dispensing operation.  The system can also be provided with a provision to "drain back" the liquid into the supply tank after the dispensing operation, and/or to recirculate liquid through the supply tank when it is desired to mix the contents thereof.

Title: Air separation
Inventor: ACHARYA DIVYANSHU R
IPC: F25J3/04
Filed: 1992-01-07
Abstract: ABSTRACT Air Separation Air is compressed in a first compressor 2 and has carbon dioxide and water vapour removed therefrom in a purification apparatus 4.  The air is then cooled by passage through main heat exchangers 6 and 8 to a temperature suitable for its separation by rectification.  The cooled air is separated in a single rectification column 16.  Liquid oxygen is withdrawn from the column 16 by a pump 34 and is passed through the heat exchangers 8 and 6 countercurrently to the air stream and is thereby vaporised, a high pressure gaseous oxygen product thus being formed.  Nitrogen vapour is withdrawn from the top of the column 6 through an outlet 20 is warmed by passage through a further heat exchanger 14 and the heat exchanger 8.  The nitrogen is then divided. One part is further warmed in the heat exchanger 6, is compressed in a compressor 22, and is returned through the head exchangers 6 and 8 as a heat exchange stream countercurrently to the oxygen product stream. The other part of the nitrogen is expanded in turbine 30 with the performance of external work and is employed to provide cooling for the heat exchanger 14.  The heat exchanger 14 is used to sub-cool a liquid nitrogen stream which is introduced into the column 16 through inlet 28 as reflux for the column 16.  The compressor 22 operates at a relatively low pressure enabling plate-fin heat exchangers to be employed.

Title: Shared-carrier frequency hopping
Inventor: KOTZIN MICHAEL D
IPC: H04J13/00
Filed: 1991-02-20
Abstract: In a TDMA cellular network, there is provided a mechanism for shared-carrier frequency-hopping. It comprises: allocating on a frame basis within a reuse diameter to one coverage area (A-I) during certain timeslot(s) at least one from a pool of TDM frame-hopped carriers and allocating on a frame basis within that carrier reuse diameter to another coverage area (A-I) during certain other, substantially non-overlapping timeslot(s) that frame-hopped carrier, all in substantially non-interfering time-synchronism with any proximal reuse of that carrier, whereby the advantages of frequency hopping are obtained. Stated differently, it comprises: at one instant in time, allocating within a reuse diameter to one coverage area (A-I) at least one of a plurality of hopped carriers and at that same instant in time, allocating within that carrier reuse diameter to another coverage area (A-I) another of that plurality of hopped carriers, all in time-synchronism with any proximal reuse of that carrier. The control and access carriers may also be included in the hopping pool, causing certain timeslots to be hopped on a sequence different from the others. The pool of hopped carriers is further apportioned among co-located sites into hopping groups, thereby reducing intra-system synchronization requirements. To solve the near/far problem, TDM timeslots bordering hopping boundaries are preferentially allocated to less distant mobile users.
