Inventor: QUARENDON PETER
IPC: G06T15/20
Filed: 1987-09-02
Granted: 1991-09-24
Abstract: ABSTRACT   A method of generating a two-dimensional (2-D) image of a transform of a three-dimensional (3-D) solid object comprises sub-dividing a 3-D box defining viewing space into sub-boxes, generating test-cells in object space by performing an inverse transform on the sub-boxes and determining which of the test-cells intersect the object.  Thus, the need to transform the object itself is avoided.  A particular application of the method is the generation of 2-D perspective images of a 3-D solid object.  A graphics processing system comprising means for performing the method is defined.

Granted: 1991-10-08
Abstract: A COLLAPSIBLE AND EXPANDABLE TENT              Abstract A tent is disclosed that is readily collapsible into a unitary flat package which can be readily stored on a hanger in a closet.   When it is desired to "set up" the tent, a pair of latches are released and the tent automatically assumes or expands into a fully "set up" or erect condition.   The tent comprises a fabric or canvas body mounted on corner posts secured to the ends of a pair of flexible bent rods arranged in criss-crossed relation.   The inherent tension in the bent rods automatically expands the tent body into its fully erect position.   The tent can be readily collapsed into a flat package by manually moving the front and back corner posts and rods together so that they lie in intersecting planes that define a small acute angle therebetween.          Latches are provided on the rods for latching the two rods and tent in its collapsed condition.

Abstract: Abstract This invention provides a process for making metal oxide varistor precursor powder comprising (a) dissolving soluble precursors of the additive metal oxides, e.g. bismuth nitrate as precursor for bismuth oxide, in an aqueous solution, (b) forming a suspension or slurry in the aqueous solution of a powder of the desired primary metal oxide, e.g. zinc oxide, having the desired particle size, (c) adding a precipitating reagent to convert the additive metal from the soluble precursor form to the oxide or hydrous oxide form and precipitate the oxide or hydrous oxide in the presence of the primary metal oxide particles, (d) removing water and by-product salts to form a powder.  The resulting varistor precursor powder contains smaller particles of the additive metal oxides evenly distri-buted throughout larger particles of the primary metal oxide.  Varistors prepared from the resulting powder can be sintered at temperatures lower than conven-tionally used, for example 900°C-1000°C and the resulting varistors exhibit properties of volts per grain boundary value higher than conventional varistors for example 3.75 to 4.5 and dielectric constants lower than conventional varistors, e.g., under 1000.

Title: Direct current adjusting device
Inventor: BAUER ALFRED
IPC: H02P7/291
Filed: 1987-12-07
Granted: 1991-06-25
Abstract: Abstract of the Disclosure Direct Current Adjusting Device The invention is directed to a direct current adjusting device for a direct current motor 3 with a free-wheeling diode which is connected in parallel with the armature winding and with a controllable switching element 2 which is connected in series with the armature winding, including a pulse duration modulator configured as a two-step con-troller and comprising a first comparator with hysteresis 10.  A control voltage Ust1 predetermining the desired rotational speed is applied to the one input of the first comparator with hysteresis 10 while its other input is connected to an integrating element 7, 9 connected to a control voltage through an electronic switch 8.  Applied to the control terminal of the electronic switch 8 is either the output of the first comparator with hysteresis 10 or the voltage at the switching point of the con-trollable switching element 2.  An additionally provided current limiting device comprising a second comparator with hysteresis 20 operates when a maximum current flowing through the controllable switching element 2 is exceeded, taking over the control of the controllable switching element 2.  A third comparator with hysteresis 30 operating in conjunction with a resistor 33  inserted in the armature circuit of the DC motor 3 and an NTC resistor 32 in thermal contact with this resistor serves the function of an electronic overtemperature protection.  A fourth comparator with hysteresis 40 monitors the operating voltage of the electronic control system in order to prevent that the DC adjuster turns on in the presence of a current flowing through the controllable switching element 2 which is lower than a predeterminable minimum value, which would otherwise result in a thermal overload of the controllable switching element 2.
