Abstract: OBJECTIVE REFRACTOR FOR THE EYE                 Abstract of the Disclosure An objective refractor for the eye is disclosed in which knife-edge optics are utilized.  The knife-edge optics cause characteristic illumination of the retina so that components of sphere and astigmatism can be identified.          Provision for remote reading of the characteristic images is provided with the result that two orthogonally disposed knife-edge images can identify the sphere, cylinder and axis required for prescriptive patterns giving the direction and magnitude of required prescriptive change.  A system of at least two orthogonally disposed, (and preferably four), knife edges with weighted lighting is disclosed for detection.          Utilization of the knife-edge images is made possible by the detection of the low light level images at a detector having low noise level.  A photo-sensitive element divided into a plurality of photo-discrete segments has light from the images proportionally dispersed over its surface.  Such dispersion occurs through a matrix of wedge-shaped segments or alternately in the form of optical elements having cylindrical components.  This dispersion of the light when used in combination with push-pull knife-edge patterns herein disclosed produces detectable low level refractive signal.          An embodiment using an optic having a plurality of side by side optic elements, each element having the effect of crossed cylinders, is disclosed with the detector. Separate independent and non-interactive positional information on one hand, and refractive information on the other hand, is provided.  Consequently the disclosed refractor is insensi-tive to adjustment and can accommodate a large range of pupil configuration with insensitivity to local retinal variations in light emission.

Title: Method and an arrangement for the removal of waste  material in rotary punching
Inventor: ANDERSSON THORBJOERN
IPC: B26D7/18
Filed: 1983-11-30
Granted: 1987-05-26
Abstract: ABSTRACT      In the rotary punching of a moving material web the punched out waste material has to be removed so as not to interfere with the course of the punching.  This can be done with the help of vacuum and internal ducts in the female roll, but this method cannot be used at high working speeds because of the centrifugal force.  Instead of this in accordance with the invention the die hole     of the female roll     is provided with pistons forming a seal which are manoeuvred to and fro in rhythm with the rotation of the roll.  As a result the punching waste     is retained for only a short while after the punching and is ejected thereafter and carried away via an external suction arrangement

Abstract: GUIDE FOR FEMORAL NECK OSTEOTOMY                      Abstract A guide for femoral neck osteotomy comprises a longitudinal rod having attaching structure at the lower end thereof for securing the rod to a femur at the greater trochanter.  A transversely extending support arm is secured to the rod adjacent the lower end thereof, and a guide bar is connected to the support arm. The guide bar has at least one elongate planar surface disposed at an angle of 45° to the axis of the rod.  In use, the rod is aligned with the long shaft axis of the femur and attached to the femur at the greater trochanter.  The rod is manipulated until the support arm and the long shaft axis of the tibia are disposed in the same plane.  This procedure pro-perly positions the elongate planar surface of the guide bar whereby an instrument in engagement with that surface traverses the femoral neck at an angle of 45° to the long shaft axis of the femur.

Abstract: Abstract This invention makes possible a substantial im-provement in the distillation column efficiencies of a cryogenic air separation process while still retain-ing high reboil rates through the argon stripping section of the low pressure column.  Those advantages result in a lower energy requirement for separating air while still yielding medium to high oxygen purity. In a triple pressure column arrangement, the medium pressure column efficiency is increased by reboiling it at two or more locations by latent heat exchange with both the high pressure and low pressure columns. The LP column vapor which reboils the MP column is taken from above at least part of the argon stripper, to maintain a high reboil rate through the stripper.

Granted: 1987-03-10
Abstract: Abstract Apparatus is disclosed to accurately measure and analyze multiple component interfering gases which coexist in the stack gas effluent generated from a combustion process which utilizes a non-dispersive, narrowband infrared absorption technique.  The apparatus includes a probe in the stack with an optical measurement cavity (34) through which the stack gases are passed. A transceiver (14) mounted to the probe includes an optical portion operatively associated with the measurement cavity including a chopped light source (54), (60), (62) for projecting beams of light into the measurement cavity and a detector (86) for detecting the attenuation of the gases to provide a measure of the extent of absorption of each gas of in-terest.  A control unit, preferably remote from the trans-ceiver, preferably a programmed digital computer, and preferably via a J-box (18) converts the electric outputs to a corresponding % modulation and in turn corrects for temperature, pressure and interference between gases.  The results may  be displayed on a front panel (174) or used, for example, to maximize efficiency in a combustion process.

Title: Metallized film wound capacitor having minimized  inductive reactance and method therefor
Inventor: LAVENE BERNARD
IPC: H01G4/32
Filed: 1985-02-25
Granted: 1987-03-31
Abstract: Abstract A method is disclosed for making a wound capacitor having decreased inherent inductance and a high self-resonant frequency.  In making this capacitor, metallized film is wound around a non-conductive poly-carbonate core and a conductor is inserted through the entire length of the core.  The wound metallized film is flattened and terminals are formed at opposite ends of the flattened wound capacitor.  The conductor is folded over and electrically connected to one terminal and a metal contact is electrically connected to the other terminal.  The electromagnetic field created around the conductor is approximately equal and in the opposite direction to the electromagnetic field created around the wound metallized film.  Therefore, the inductive reactance of the conductor and the inductive reactance of the wound film are approximately equal.  These reactances approximately cancel resulting in increased self-resonant frequency.
