Abstract: A swim fin having open instep and heel portions. The swimmer's foot is retained in the fin by means of an instep strap configured to pass over the instep of the foot and a heel strap that surrounds the heel of the foot. The instep strap passes through a pair of longitudinal slots in the planar foot portion of the fin and up and over the foot such that the ends of the instep strap are secured at the instep. Preferably, to facilitate adjustments, the ends of the instep strap overlap one another and are secured with hook and loop fasteners. A locking strap overlays the instep strap at the instep of the foot and further secures the fin to the foot. The instep strap conforms to the instep of the foot and lends itself to enclasping the arch of the swimmer's foot. Preferably, the heel strap is integrally formed from the instep strap and the ends of which overlap one another are secured with hook and loop fasteners. A heel locking strap overlays the heel strap at the ankle and further secures the fin to the foot.

Abstract: The invention pertains to a homodyne receiver and a process for direct conversion of angle-modulated carrier signals, especially those that have a d.c.-voltage component in the converted signal (IF). With many types of-modulation the (short-time) d.c. component of the conversion signal contains information about the modulating signal. Additional d.c. offsets are usually separated out by using a bandpass for the IF signal. In the process, however, the information-containing d.c. components of the converted signal are lost; as a result the demodulated signal is disturbed and in particular the distortion factor is raised. To avoid this the invention provides that the local oscillator for generating inphase and quadrature signals has a frequency offset from the carrier frequency of the receiver signal so that the frequency differential between carrier and frequency and oscillator frequency is in the transmission band of the bandpass used to suppress undesirable mixes, carrier reminders and d.c. offsets.

Abstract: A wafer shielding chamber assembly for a semiconductor wafer probe station that minimizes the volume of space about the semiconductor wafer so as to minimize air currents about the wafer. The chamber is formed by positioning an annular spacer ring onto the annular periphery of the wafer chuck. A lid is positioned to free-float underneath the support ring of the probe station. The free-floating of the lid permits the upper surface of the spacer ring to engage the lower surface of the lid as the wafer chuck is moved in the z direction and, upon further z movement, moves the lid into the z direction, while still permitting x & y movement between the two. A center hole is formed through the lid. The center hole provides access for the micropositioners contact probes to the wafer. A cylindrical cap assembly is positioned on top of the lid concentric with the center hole.

Abstract: A disposable portable pocket spittoon comprising a container having a top access opening. A means for selectively closing and opening the container is connected to the container. A fill funnel is inserted through the top open end and suspended within the container in order to direct spittle within the container. An absorbent material is retained within the container to immediately absorb a tobacco chewer's expectorate and which will not release the expectorate. This spittoon is intended to be used with only one hand and permit concealment of the container in a tobacco chewer's pocket with out spilling.

Abstract: A method of repairing a cornea of an eye. A donor material of living tissue in the shape of a partial sphere having an exterior Bowman's membrane of living tissue, is first die cut to define an outline configuration including a central extent and a plurality of tabs extending outwardly therefrom. The tabs are then shaved to remove substantially all of the donor material therefrom leaving substantially only the Bowman's membrane. The eye to be repaired is then punched to form a central aperture in the cornea having a size and shape essentially that of the central extent of the donor material. A plurality of pockets are incised from the central aperture into the cornea, the pockets being positioned and sized and shaped to receive the respective shaven tabs when the central extent is positioned within the central aperture.
