Title: Digging implement and blade therefor
Inventor: GERBRANDT GEORGE
IPC: E01H5/04
Filed: 1988-08-17
Granted: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE      A blade is provided for a digging implement, especially a snowthrower.   The implement is of the type having an auger blade arranged for advancement sideways into a body of material to be removed.   The blade con-sists of a band with a leading edge wound along a blade axis,  preferably  helically,  and  a  tapered body  that slopes towards the axis away from the material discharge of the device.  In the case of a snowthrower, where the material discharge is at the center, the blade will have two sections, wound oppositely around the blade axis and tapering in opposite directions towards the axis,  away from the centre discharge.  The blade performs a slicing action on the material to be removed rather than scraping material from its face as is the case with the conven-tional snowthrower and analogous implements.   The blade is thus aggressive and draws itself into the material, reducing the power requirements of both the blade and the system for propelling it into the material.

Title: Fluid-carrying components of apparatus for automatic control of intraocular pressure
Inventor: ARMENIADES CONSTANTINE D
IPC: A61B5/022
Filed: 1988-10-14
Granted: 1993-04-27
Abstract: FLUID-CARRYING COMPONENTS OF APPARATUS FOR   AUTOMATIC CONTROL OF INTRAOCULAR PRESSURE                     Abstract An ophthalmic device and system for measuring and controlling relative fluid pressure inside an ocular globe includes  a  surgical  instrument which is adapted to penetrate the ocular globe.  A fluid pressure transducer is mounted on the instrument so that when the instrument penetrates the ocular globe the transducer is located adjacent to an opening that communicates with the interior of the globe so that it can react to pressure changes in the fluid therein and generate signals in response to changes in the pressure of the fluid.  The signal is transmitted external of the instrument to a control system which is operatively connected to the transducer for first receiving signals from the transducer and then controlling a fluid supply system in response to signals according to a predetermined set of instructions.  The control system is connected to a closed loop feed system in which fluid is continuously circulated.  Fluctuations in intraocular pressure cause the control system to divert fluid from the feed system to the ocular globe to a conduit connected to the closed loop.

Title: Plug-resistant arch-vent for a tire mold
Inventor: ROCKARTS RENE L
IPC: B29L30/00
Filed: 1989-02-02
Granted: 1993-03-30
Abstract: PLUG-RESISTANT ARCH-VENTS FOR TIRE MOLDS                 ABSTRACT OF THE DISCLOSURE     A split tire mold having a tread ring in which provi-sion is made for venting air circumferentially across the inner surface of the tread ring so that the air escapes from the parting line of the mold halves, dispenses with widely used, conventional, radially protruding vent stubs. The air is vented through "butterfly-shaped" or "double-wedge-shaped" arch-vents which provide passage for trapped air above each tread block of the tread as it is moved against the inner surface of the tread ring. The shape of the arch-vent passages and the angulation of the wedges is critical to the effectiveness of the arch-vent which forms an arch-vent bridge of cured rubber in a cured tire. The configuration of the bridge allows a cured tire to be easily removed from the mold cavity without leaving a broken-off piece of the rubber bridge to plug the arch-vents. This arch-vent design leaves unobtrusive flat-sided, narrow wedge-shaped pieces of rubber as the arch-vent stubs, tapered in two directions. The arch-vent stubs, when viewed in the radial direction towards the center of the tire, are so unobtrusive as to be cosmetic-ally acceptable in a finished tire. The upper surface of the arch-vent is close to the inner surface of the tread ring and essentially horizontal, while the lower surface of each arch-vent is inclined at an angle in the range from 30°-50° to the horizontal plane, but in opposite directions. An angle in this range provides surprising strength in the base area of the arch-vent stub so that, upon stripping the tire from the mold, the arch-vent bridge of cured rubber breaks cleanly and reliably at the narrowest and weakest point in the bridge.
