Title: Combination switch and variable resistor system
IPC: H01C10/20
Filed: 1967-04-27
Abstract: A combination of an electric switching device and variable resistor comprises at least one resistive element 42, a contact (47), (Fig. 2, not shown), mounted so as to be movable along and in contact with the or either resistance element and to be movable to a rest position, as shown, where it is out of contact with the or each resistive element, a pivoted arm 22 operated by a wheel (14) for moving the contact along the or either element, and a coiled sprirg (8) biasing the contact to said rest position when not being moved. If two resistive elements 41, 42 are used, these are separated by a region covered with highly conducting material 38 and provided with a projection 48 such that in the rest position the arm 43 supporting the contact is resiliently biased away from the resistance tracks by the projection. When wheel (14) is turned, arm 22 is caused to pivot due to the forces exerted on the extrusions 27, 28 by the linkage 19, the contact (47) contacts area 38 as the arm 43 slips off projection 48, and then moves on to either resistance strip 41, 42. A reference potential is applied at 40, i.e. earth, and positive and negative potentials at opposite ends 37 of the resistive elements. The resistive elements are formed by coating arcuate members 33, of insulating material such as phenolic resin attached to the base for example by bonding, with resistive material 34 which may be a quick drying bonding agent with sintered conductive medium dispersed therein, e.g. varnish containing carbon particles. The layer 38 may be of varnish containing silver particles. Projection 48 may be of P.T.F.E., and arm 43 of phosphorbronze. Gears may be used to move the wiper arm, or it may be moved manually. An indicating scale may be included (Fig. 1, not shown).

Patent ES-430383-A1 (ES)
Title: Speed measurement system
IPC: H03L7/06
Filed: 1974-09-25
Abstract: A system adapted for the measurement of ship's speed by utilizing the doppler shift imparted to sonic energy reflected from the bottom of a body of water or from sources of reflection within the water itself. Pulsed sonic transmissions are directed from the ship at an angle to the vertical to provide a forward or aft component to the received doppler frequency signal. The received signal is translated to an intermediate frequency lower than the received frequency and the elapsed time of a predetermined number of cycles at the intermediate frequency in each of a succession of received pulse signals is measured. After ascertaining the equality of successive ones of these measurements, the system provides for the storing of successive ones of these measurements and the generation of a periodic pulse train signal having a frequency dependent on these measurements. The pulses of the pulse train wave are then counted during fixed time intervals to provide a number representing the doppler frequency shift and the corresponding speed of the ship.

Title: Magnesium reclamation process and apparatus
IPC: C22B26/22
Filed: 1976-10-22
Abstract: A magnesium reclamation process whereby magnesium and magnesium alloy fines, chips and scraps may be recovered and remelted for reuse. The method is comprised of the steps of pelletizing the magnesium by first compacting the magnesium with a low pressure press so as to initially expel the majority of the air, followed by a high pressure press under a controlled environment to form a compact pellet. The pellets are then melted either by stacking on the cold heel of a pot and heating under a controlled environment or pre-heating in a basket over a melt, and then subsequently immersing the load. Melting can also be accomplished by controlled melting, utilizing an induction melting furnace whereas temperature can be slowly increased. Pelletizing pressures range from approximately the yield pressure to the cold welding pressure of the material being reclaimed. A typical pelletizing environment is 20% SF6 and 80% CO2 and a suitable melting environment is 98% CO2 and 2% SF6.

Title: Method of vehicle engine control
IPC: B60W30/18
Filed: 1978-03-31
Abstract: In the regulation of a motor-drive unit for a motor vehicle having a heat-engine and a continuously variable ratio transmission, in a clutch-engaged phase the heat-engine fuel feed is controlled so that it is a function of the displacement of the accelerator pedal of the vehicle and of the speed of the heat-engine such that the power delivered by the engine is substantially equal to the power required for that displacement of the accelerator pedal. In addition, the transmission ratio is controlled so that the speed of the heat-engine approaches an ideal speed which depends upon the power required and is predetermined for operation of the motor-drive unit which is optimalized in accordance with a chosen criterion. Operation is thus obtained with, for example, minimum consumption or pollution while taking into account, in the transient phase, the operation desired by the driver.
