Patent FI-77135-C (FI)
Inventor: KRUMMEL PETER
IPC: H02H9/04
Filed: 1983-11-15
Granted: 1989-01-10
Abstract: In an inverter controlled with a firing unit connected to switches and defining an operating frequency, a resonant frequency of a series oscillating circuit of the inverter connected to one of the switches is placed below this operating frequency. Given this operating situation, a short of the d.c. voltage source is impossible. Given, for example, unfavorable component tolerances, however, the operating frequency can be moved close to the resonant frequency and cause impermissibly high voltages at the components. Such a voltage rise is limited according to the invention by means of a voltage-dependent resistor. It preferably lies in series with a capacitor and takes care of a voltage-dependent shift of the resonant frequency.

Abstract: The rollers or curved rods and other elements supporting the glass sheets as well as the apparatus necessary for bending and/or tempering are preferably mounted on a pair of longitudinally flexible strips that rest on a pair of rigid templates having the desired curvature. Each flexible strip advantageously is a chain whose links are hinged on one another, these links being provided with flanges to which are fastened the rollers or curved rods, all other elements for supporting the glass sheets, and the elements necessary for bending and tempering. To permit modification of the curved profile, the templates are removable and interchangeable. To facilitate changing of the templates, the apparatus is equipped with a system for lifting the strips or chains. Such lifting system comprises one or more pivoting beams that are lifted by drive means such as a jack and a bent connecting rod. When the beams are raised, they lift the strip or chain off the template, thereby freeing the template to be replaced with a template having a different curvature.

Abstract: The present invention is directed to a sandblasting unit for texturizing objects, and a method of using the unit.  The sandblasting unit includes a frame and a housing, with a sandblasting nozzle positioned within the housing.  A conveyor belt moves the objects, such as concrete blocks, through the housing for treatment or texturizing by the sandblasting particles.  The nozzle emits a spray of sand-blasting particles which disperse to cover an enlarged area, with a concentration of particles in a central locale within the coverage area.  A protective baffle plate blocks the spray in the central locale so as to eliminate the concen-tration of spray therein and thereby produce a uniform texturized surface on the object.  The baffle plate is adjustably mounted within the housing so that the desired uniformity of texturizing can be achieved.  The unit also includes a collection funnel for collecting the used sand-blasting particles and vents for suctioning away the waste material sandblasted from the object.

Title: Solid waste disposal unit
Inventor: KYDD PAUL H
IPC: F23G5/027
Filed: 1990-05-09
Granted: 1995-06-27
Abstract: A solid waste disposal unit having a lower, pyrolyzing chamber and an upper, oxidizing chamber separated by a movable plate.  Waste is deposited in the lower chamber.  the chambers are rotated to move the plate to a first position which seals the lower chamber from the entrance of air.  While the chambers continue to rotate, a pair of heaters separately heats the chambers.  The waste in the lower chamber is pyrolyzed in the absence of air and gives off a combustible vapor that in turn is oxidized in the upper chamber.   A plurality of venturi jets, mounted in the movable plate, mix the vapor with air as the vapor passes into the upper chamber.   Additional air is introduced into the upper chamber through a rotating regenerative heat exchanger recovering heat from the exhaust gases.     After the waste is thoroughly pyrolyzed into a char, the rotation of the unit is reversed causing the movable plate to rotate into a new position wherein air is permitted to enter the lower chamber to cause oxidation of the char.   This oxidation process continues until the char is entirely consumed and reduced to a sterile ash.  Any gaseous products produced will continue to be oxidized in both chambers.

Title: Read/write random access memory with data prefetch
Inventor: HOFFMAN STEPHEN WAYNE
IPC: G06F9/52
Filed: 1990-06-07
Granted: 1997-12-09
Abstract: A dual port, random access, read/write memory is provided such that each microprocessor can access shared memory locations without regard to the state of the other microprocessor.  Previously known dual port systems use delays, called wait states, or handshaking techniques to control memory access and to resolve overlapping memory access requests.  This invention avoids the need for special timing controls by improving memory response time.  Once a valid address is placed on the address bus by the microprocessor, which is recognized by the memory as being within its range of assigned address values, the memory prefetches the data at that address on the chance that a read request for that address may soon follow.  If it does, then the data is placed on the data bus.  If it does not, then the prefetched data is ignored and a write operation takes place for the particular address.

The mold then opens in a manner in which the first and second mold sections are opened which then allows  the mold parts of the first mold section to open for releasing the product from the mold.
