Abstract: An automatic control device for a boundary plate of a grain separator for separating a grain mixture into different grains. The grain separator has a separator plate provided with a roughened surface and mounted at inclinations in both of longitudinal and lateral directions with respect to the horizontal plane. A lateral movement is imparted to the different grains on the separator plate by a lateral oscillation given to the separator plate or by a lateral jet of air jetted from a numerous small aperture formed in the separator plate, so that the flow fluxes of different grains are deflected away from each other due to the difference in the physical properties such as specific weight and/or friction coefficient, so that the mixture of different grains are separated.

Abstract: This invention relates to an improved method of relining a sewer especially a small diameter sewer with a plurality of lengths of pipe.From a control station remote from the sewer, pipes are moved up the sewer to the fixed lining.

Abstract: A valve which is to be used as a component of plastics bags and trays for packaging foodstuffs and other perishable goods. The valve consists essentially of a small spherical chamber having an inlet and an outlet. The chamber is made from two hemi-spherical walls having different resilience. In order to close the valve one wall is made to spring into contact with the other wall so that the two walls enter into such close intimate contact that communication between the inlet and the outlet through the valve is prevented.

Abstract: An intraocular lens having a hydrophilic optical element. The hydrophilic material of the optical element is capable of being hydrated by the natural fluid in the eye to expand after implantation to provide an optically correct lens of suitable diameter, to permit implantation of the lens through an incision of minimal length corresponding to the diameter of the dry lens and thus restoring the vision of the patient with minimal trauma. The lens includes position-fixation members and connecting means for securing the hydrophilic optic to the position-fixation member. The position-fixation members are connected to the hydrophilic optic element in such manner that the lens can be seated in the eye prior to expansion of the hydrophilic optic and expansion after seating does not impact substantial movement to the position-fixation members. The invention also includes the improved method of implantation through an incision of minimal length.

Inside the chamber are two pivotally mounted cathodes each having coating material to be sputtered applied to a surface thereof. The cathodes are mounted to pivot between the withdrawn position lying clear of the disc path and operating position wherein the cathodes lie one to each side of the disc when this is in the coating position. Means are provided for rotating the support means and thus the disc about the disc center when in the coating position and during such rotation coating material is sputtered from the cathodes simultaneously onto both sides of the disc.

Abstract: A regenerative braking system for a linear induction motor includes a control device to increase the frequency slip in a braking mode and reduce the regenerative capacity of the motor. The control device is regulated by sensing means which monitor the voltage of the external power conductor and increase the slip if the voltage exceeds a predetermined value. This reduces the power regenerated by the motor and prevents excessive voltages in the conductor. A latch prevents cycling between the full and reduced regenerative braking to prevent oscillation of the braking force and is reset upon selection of a motoring condition for the motor.
