Abstract: A holder for a bit is disclosed. The bit may include a first locking element. The holder may include a housing; a base assembly including a first hole; a second locking element partially disposed within the first hole and configured to move between a locking position in which the second locking element engages the first locking element to prevent removal of the bit, and an unlocking position in which the second locking element is spaced from the first locking element allowing the bit to be removed; and a follower assembly contained within the housing and configured to move relative to the housing and base assembly between a first position in which the follower assembly supports the second locking element in the locking position, and a second position in which the follower assembly allows the second locking element to move from the locking position to the unlocking position.

Abstract: Automatic valve actuator apparatus and valve actuator assemblies are disclosed. The automatic valve actuator apparatus may include a sensor assembly configured to detect a condition and transmit a sensor signal indicating detection of the condition, and a valve actuator assembly configured to be attached to the manual valve and to move the manual valve between open and closed positions. The automatic valve actuator apparatus may additionally include a control assembly configured to receive the sensor signal and to transmit a first control signal to the valve actuator assembly based, at least in part, on the sensor signal. The valve actuator assembly may be further configured to receive the first control signal from the control assembly and to move the manual valve toward the closed position in response to receiving the first control signal.

Abstract: Camera accessories configured to couple a camera having a camera optical axis and a scope having a scope optical axis are disclosed. Additionally, camera accessories configured to couple a smart phone having a camera with a camera optical axis and a scope having a scope optical axis are disclosed. The camera accessory may include a locking mechanism configured to selectively secure the portion of the scope to the scope-receiving assembly such that, when the camera is attached to the camera-receiving assembly and when the scope is received by the scope-receiving assembly, the camera optical axis coincides with the scope optical axis.

Abstract: A thermal transfer printing sheet comprising a substrate having a coating comprising a dye of the formula:A--N.dbd.N--EwhereinA is a phenyl group substituted by at least one electron-withdrawing group selected from NO.sub.2, CN, CF.sub.3, halogen, --SO.sub.2 --C.sub.1-4 -alkyl, --SO.sub.2 F, --SO.sub.2 CF.sub.3, --SO.sub.2 NRR.sup.1, --CONRR.sup.1, --COOR, --CO--CO--R, wherein R and R.sup.1 are independently selected from H and C.sub.1-4 alkyl, provided that where A carries only two halogen atoms these are not in the 2- and 6- positions in relation to the azo link;and E is the radical of an aniline, a tetrahydroquinoline, a lilolidine or a julolidine coupling component, and a thermal transfer printing process for the coloration of a polymeric substrate using the thermal transfer printing sheet.

Abstract: A rubbish segregating and collection system makes use of a transporter that is placed at a town dump. The transporter has several containers to receive different classes of rubbish, each of which containers is removable from the transporter. When filled, the transporter is placed on a carrier and replaced with another transporter. The filled transporter is carried to a central collection and segregation facility where the individual containers tare weights may be determined following which their contents are dumped and inspected as necessary. The segregated rubbish is then transported to the appropriate reclamation centers for each class of rubbish. The preferred type of bottom jaw-like opening individual container is also claimed.

Abstract: A dry etching process for aluminum uses a silicon tetrachloride gas ambient to which is applied radio frequency power for ionizing the gas. By appropriate control of the gas pressure and power density, anisotropic etching is achieved. This gas system also is useful for etching dual layers of aluminum and doped polycrystalline silicon.

Abstract: High density fine-line integrated structure fabrication is expedited by use of plasma etching systems which assure straight vertical walls (absence of undercutting). Critical to the sytems is choice of appropriate plasma chemistry. Appropriate systems are characterized by inclusion of recombination centers, as well as active etchant species. Recombination centers which effectively terminate etchant species lifetime in the immediate vicinity of resist walls afford means for controlling etching anisotropy. Use is foreseen in large scale integrated circuitry (LSI) and is expected to be of particular interest for extremely fine design rules, i.e., in Very Large Scale Integrated circuitry.

Abstract: A method of forming patterned insulating layers such as silicon nitride for use in integrated circuit fabrication is disclosed. The insulating layer is formed by reactive plasma deposition while the temperature of the substrate is decreased. This diminishing temperature affects the etching characteristics of the layer such that when openings are formed by a selective plasma etching, the sidewalls will be sloped at an acute angle with the substrate even when the layer is overetched.
