Title: Insecticide and insect repellant compositions
Inventor: JAMES LYNN S
IPC: A61K31/16
Filed: 1994-08-18
Abstract: A non-toxic, environmentally safe and easily employable insecticide and insect repellant is achieved by providing an aqueous composition incorporating ethanolamine based compounds, either independently or in combination with the ethanolamine based compounds being selected from both simple compounds and conjugated compounds. In one preferred embodiment, a highly effective composition is attained for safe, effective, direct topical application to humans and animals by employing between about 10% and 70% by volume of the entire composition of the ethanol-amine-based compound. In alternate preferred embodiments, the insecticide is formulated for application to plants, trees, crops, and other vegetation to provide a composition which effectively controls bothersome insects, while being completely safe and non-injurious to the plant, tree, or crop, as welt as to the flowers or fruit thereof. In addition, the compositions of this invention are completely biodegradable, and are safe to the environment and water supplies.
Patent CA-2132839-A1 (CA)
Inventor: GROEN HENRY J
IPC: B64C27/59
Filed: 1993-03-25
Abstract: An autogyro (10) has a teetering semi-rigid rotary wing (28) with rigid rotor blades (30a, 30b). The blade pitch of the rotor blades (30a, 30b) is fully adjustable in flight and varies along the blade length. A prerotator (100) rotates the rotor blades (30a, 30b) up to takeoff speed at minimum drag, no lift and optimum engine efficiency. Engine power is disconnected from the rotor blades (30a, 30b) and their angle of attack is changed for optimum lift. Rotor blade pitch is adjusted during vertical landing. In flight, rotor blade angle of attack is varied to adjust autorotation, lift and drag at any flight airspeed. On the ground, the rotary wing (28) is braked to prevent rotation. The autogyro (10) may roll, pitch or yaw, with complete independence of blade pitch with respect to all other relative motions. The pedals (61a, 61b) have disproportions forward and backward motions.

Patent CA-2135963-A1 (CA)
Inventor: ENDO KAORU
IPC: G01R31/36
Filed: 1994-11-16
Abstract: A battery-driven electronic appliance comprises means for generating the threshold voltage value for selectively setting two (high and low) threshold voltage VH or VL depending on whether a specific load, for example, a motor 20 of a group of loads of a battery 15 is operating or not and a battery voltage monitor 21 for determining the advent of the replacing or recharging time of the battery depending on whether the output voltage V 0 of the battery 15 is greater or smaller than the threshold value.  Thus, it becomes possible to prevent mistaken determination resulting from the operation of the specific load which is great in power consumption to prevent the memory effect from occurring in, in particular, the secondary battery to enable its effective use until the lifetime of the battery is reached.

Title: Display with enhanced highlights
Inventor: LOVISON DOUGLAS I
IPC: B41M3/06
Filed: 1994-11-29
Abstract: A display has a transparent plastic substrate and a colored image formed on the substrate.  The colored image is formed on the substrate by process printing a large number of small dots, colored red, yellow, and blue, in a predetermined pattern onto the substrate.  The red, yellow, and blue ink dots are translucent to visible light.   A pattern of opaque white ink dots is process printed over selected portions of the image to highlight the selected portions  and to thereby give the selected portions an appearance of relative depth.  A reflective layer can be deposited against the ink patterns to reflect light which passes through the ink patterns and thereby give the image formed by the ink patterns a shiny, metallic appearance.

Abstract: In a display system suitable for high ambient light environments, a lamp is used simply as a light source to illuminate a rear projection display screen, which is a matrix of tiny cells that modulate the light at video rates.   Each cell  includes a polymer dispersed liquid crystal (PDLC), a focusing lens and a pinhole aperture. When the PDLC is electrically activated,  light passing through the PDLC is scattered in many directions, and very little light passes through the pinhole aperture and is seen by the viewer.   When the PDLC is not electrically activated, light passing through the PDLC is not scattered, the lens of each cell focuses the light through the pinhole aperture, and the viewer sees a bright spot of light.

Filed: 1996-01-26
Abstract: A method and a device, in a mine hoist, for damping the vertical oscillations which may arise in the skip/skips (8, 9) of the mine hoist during different operating conditions. According to the invention, with the aid of a Kalman filter in the form of an estimator (12) based on a state model of the mine hoist, estimated values of the speed (z1, z2) of the skip/skip may be obtained. with access to these estima-ted values, the torque control, included in the speed con-trol of the mine hoist and superimposed on the torque which is required from the speed controller (1) via a torque control generator (13), may be given a torque addition which acts in such a way that, as soon as differences arise between the speed of the rope drum nltr of the mine hoist and the estimated speeds of the skips, the tendencies to oscillations are counteracted and reduced after a short building-up process (Figure 5).
