Title: Laser alignment system for small arms
Inventor: PARIKH HIMANSHU N
IPC: F41A33/02
Filed: 1995-04-28
Granted: 2001-03-27
Abstract: An electro-mechanical fixture automatically aligns a laser transmitter bolte d to the stock of a rifle for subsequent use by a solder in war games. A recta ngular hollow case is horizontally oriented and a hinged end cover is swung upwardl y toreveal an LCD display and keypad of a control unit. A sliding rack is extended horizontally from a base unit inside the case. The barrel of the rifle is su pported on a weapon rest mounted to the base unit and the trigger guard or clip rece ptacle is mounted in a vise on the rack. The vise has knobs for adjusting the azimu th and elevation of the weapon, thereby permitting the soldier to aim at an ima ge of a target reticle. An optics unit is mounted on a forward portion of the base  unit and includes a lens and a beam splitter which is transparent to infrared lig ht from the laser transmitter but reflective to visible light. The illuminated targe t reticle is mounted inside the optics unit below the axis of the laser beam. The beam sp litter is positioned forward of the lens and is angled at forty-five degrees to pro ject the image of the target reticle through the lens at infinity. A position sensor detector in the optics unit receives the laser beam and generates an error signal representative of a displacement between a received location of the laser be am and the image of the target reticle. A circuit in the control unit is connected to an alignment head which is mechanically coupled with a rear end of the laser transmitter bolted to the rifle. The circuit causes the alignment head to re petitively trigger the laser in the laser transmitter. Utilizing the error signal, the circuit causes the alignment head to independently rotate wedge prisms in the laser transmitter to steer the laser beam in azimuth and elevation until the laser  beam is substantially aligned with a boresight of the weapon.

Abstract: The packing and even the excessive packaging of products for human consumption is a current practice in the industrialized countries. As this packaging is made primarily of non-biodegradable polymers, they currently cause environmental problems. These environmental problems are found not only in industrialized countries but also in developing countries. This situation supported the development of various films, more ecological, starting from biodegradable elements containing polysaccharides, proteins and/or lipids. We developed a biodegradable protein film from a casein salt of dairy origin. Casein is abundant and could even be recovered from unsold milk. The process of polymerization is induced by gamma irradiation. Indeed, the interaction of hydroxyl radicals with tyrosins present in protein creates a covalent bond (bityrosine). The addition of a plasticizing agent is essential in order to produce a more flexible and less friable film. The presence of glycerol does not inhibit the formation of bityrosine. It protects protein from the denaturation caused by irradiation, increases the deforming capacity and decreases the breaking strength of film. The biodegradation tests, carried out in our laboratories, showed that the film produced by gamma irradiation is accessible to the enzymatic attacks from Pseudomonas fragi.

Title: Method and apparatus for improving the effects of color burst modifications to a video signal
Inventor: WROBLESKI WILLIAM
IPC: H04N5/91
Filed: 1996-11-05
Granted: 2001-07-31
Abstract: In the known color stripe process for preventing recording of video signals, the color burst present on each line of active video is modified so that any subsequent video tape recording of the video signal shows variations in the color fidelity that appear as undesirable bands or stripes of color error.  This color stripe process is improved by a combination of modifying the phase of the color burst on only part of the color burst. Additional improvements were obtained by incorporating techniques of widening the normal color burst envelope towards the trailing edge of horizontal sync and towards the beginning of active video. These techniques are useful in improving the performance of the color stripe process in both the NTSC and PAL color systems. However, additional improvements are described in the PAL system whereby the phase modifications are controlled so as to avoid disturbing the so-called PAL ID pulse. Such avoidance of the PAL ID pulse improves the playability of the color stripe signal in the PAL format.

Abstract: A system for controlling pasteurization of packaged food product in tunnel-type pasteurizers, having a first zone for subheating, a second zone for heat treatment and a third zone for cooling. The zones include thermally independent subzones, some of which comprise heating and cooling means. Data detection and processing means measure and record a temperature of the product in each zone or subzone, to identify when the product first reaches a selected pasteurization temperature in the second zone; maintain it at the selected pasteurization temperature for a required period of time; and only after that period, lower the temperature to a predetermined value which is maintained until the product leaves the second zone. The product is thus maintained at the pasteurization temperature for the correct time period, is heated and cooled only once, regardless of conveyor stoppages, thus avoiding the risk of insufficient pasteurization or over--pasteurization, and saving thermal energy.

Abstract: A remote drop box can be provided for tractor hydraulic drives; however, a system for providing lubrication to and cooling of the remote drop box is necessary. Maximum drawbar pull and maximum road speed capability are both,desirable when a variable hydrostatic motor defines the working range. The hydrostatic motor must be operated very close to its maximum rated operating speed during roading, which leaves very little margin for overspeeding that occurs when the tractor is roading downhill. An improved overspeed control is also desirable. A problem encountered when a hydrostatic drive is used with a high torque engine in that, as the engine speed drops, the available charge pump flow also drops and eventually reaches a point where the required servo pressure to maintain the hydraulic pump in stroke cannot be maintained. Such a condition needs to be alleviated to provide an effectively operating hydrostatic drive system. Load sensing hydrostatic drive systems can encounter vibrational or surging problems, particularly when flow compensators in valving interact with the flow compensator of the hydraulic pump. This interaction will cause rhythmic flow pulsations or surging within the hydraulic system, which is undesirable. Stabilizing the hydraulic system can be accomplished with an attenuator/hose assembly.
