Abstract: In this method an artificial lens is implanted in an eye in which the crystalline portion of the natural lens has been surgically removed through an opening made in the anterior wall of the lens capsule and through a small incision in ocular tissue at the front of the eye. This method utilizes an expansible bag that has a transparent body portion containing a cavity and an entrance opening to the cavity through which filler material can be introduced into the body portion. The body portion of the bag is inserted through the small incision and through said opening in the anterior wall of the lens capsule into a position where at least a portion of the body portion is located within the still-remaining portion of the lens capsule. Then the body portion is distended by introducing filler material through said entrance opening, and the distended body portion is located within the still-remaining portion of the lens capsule in a location adjacent the posterior wall of the capsule.

Abstract: An automatic teller machine (ATM) is provided with apparatus for turning it betweeen its normal-operating position and its service-access position. Turning occurs about a vertical axis that is moved transversely of itself during turning so that the ATM can be used in an enclosure of minimum dimensions. The turning apparatus comprises: (a) a jackscrew mechanism mounted on a base and coupled to a carrier for the ATM and (b) two cam connections between the base and the carrier for controlling during turning the paths of the carrier and said vertical axis.

Abstract: An on-board oil quality monitor includes a tube for recirculating oil from an engine, which tube has a transparent portion located within an infra red generator and detector that produces a signal indicating excessive oil contamination when the generated infra red that is transmitted to the detector is below a certain threshold.
Abstract: A reflection densitometer includes an optical assembly formed with an ellipsoidal internal reflecting surface receiving light from a specimen at a target region located at one focus of the ellipsoidal surface and directing light to a photodetector at the other focus. A light source is mounted concentrically within the ellipsoidal surface, coaxially with the target and photodetector.
Abstract: A digitally programmable attenuator for high speed and a large dynamic range is constructed with a phase-controlled attenuator for small steps of attenuation and an attenuator of switched resistive pads for larger steps. The attenuators are connected in tandem and actuated combinatorially with the phase-controlled attenuator being switched into operation for the small steps, and the resistive pads being switched into operation for the large steps. A phase-controlled attenuator is constructed to permit adjustment of the attenuator characteristic, and a switched-pad attenuator is constructed to be phase shiftless.
Abstract: A radiation detector for free space microwave radiation uses thin film resistive strips, having an equivalent surface resistivity that is large compared to the characteristic impedance of free space, and diode circuits in series with the strips for deriving d-c signals monitoring the radiation intensity over a broad frequency range. In part of that range, the strips operate like a short dipole antenna. The diode circuits are constructed to operate with a uniform response over the entire frequency range.
Abstract: A microstrip hybrid coupler uses a ground plane having different surfaces, one that is close and coupled to the terminal portions of the microstrip and the others further from and coupled to the coupled microstrip portions. Two shields extend over the coupled microstrip portions; an intermediate shield between the remote ground plane surface and the coupled microstrip portions and an outer shield. The coupled microstrip portions extend over the terminal surface of the ground plane.
Abstract: This invention relates to an analog phase shifter for radio frequency signals that employs a hybrid coupler and biased varactor diodes at its reflection terminals. The diodes are operated so that the normalized reactance is unity (equals the coupler's input impedance) at an intermediate frequency which may be the geometric mean of the end frequencies of a broad bandwidth. The couplers are cascaded in tandem for a 360.degree. phase shift. A balanced configuration of hybrid couplers is used for the phase shifter.
Abstract: A traction device for removable attachment to a user's shoes to assist in walking on ice has a steel plate with depending ice-piercing teeth and an elastic attachment band. The teeth lie in transverse planes and are struck and bent from a flat plate.
Abstract: A swimming pool lift installation for the handicapped employs a platform for carrying a wheelchair that is lowered and elevated with the platform so that a handicapped person can sit on his chair and be lowered into the pool for swimming away from the chair and can leave the pool by swimming back into the wheelchair. The chair is releasably secured to the platform so that there is no danger of it being rendered unstable by its buoyancy in the water and so that it can be wheeled on and off the platform. A water hydraulic system operates the lift to avoid contamination of the pool.
Abstract: An ejector for a sequence of game balls has variable device for setting a different trajectory for each ball and for varying the time interval between each ball delivery. A controller includes an input device used by the tennis player or instructor to enter the court and ball data for each of a sequence of balls; a converter for changing the court and ball data to corresponding trajectory data used in setting the ball ejector; and a digital memory for storing the data for each ball. The controller is switched to a programming mode for setting up the court and ball data for the sequence of balls to be delivered and to an operating mode in which the balls are delivered in accordance with the set program.
Abstract: A data processing security system employs a secure enclosure, such as a vault, for all cryptographic processes, and the maintenance of digital information in storage outside of the enclosure in encrypted form and when not in use by the host computer system, where the information is used in plain text form and which communicates with the enclosed encryption system by a standard interface.

Abstract: This surveillance system employs a closed circuit television camera or cameras used in conjunction with an electronic cash register or registers employed at one or more point of sale stations. Combined images of transaction items viewed by a camera at a given station and transaction data (such as prices) rung up on the cash register at said station are presented on a television monitor. Signals for these combined images are also stored on video tape together with coded signals related to transaction data to achieve computerized editing.
Abstract: A method is disclosed of sorting data in an electronic data processing system utilizing a digital computer and at least one random access device such as, for example, a magnetic disc or drum unit. A first simulation is performed to optimize the utilization of the resources of the data processing system. This simulation is based on information relating to characteristics of the data processing system available to the sorting function as well as known or predicted information concerning the data to be sorted. The input data is ordered into a plurality of strings of data which are generated by a selection technique known as quadratic selection replacement. The number of strings generated is minimized by determining if data bias exists, and if unfavorable or negative bias is discovered, the order of string generation is reversed.
