Title: Ergonomic-interface keyboard system
Inventor: SPENCER JEFFREY B
IPC: B41J5/10
Filed: 1992-08-05
Abstract: Conceived with the human-engineering objective of overcoming Repetitive Motion Injuries such as Carpal Tunnel Syndrome. The solution, a system comprising a split-keyboard spaced laterally into vertically arranged co-operative keypad halves, optimally enabling the user to sit with the lightweight portable keyboard assembly laying directly upon their lap. Traditional keyboards orient operator's hands inducing a wrist-twisting, arm-extending stress while the stress-free ergonomic bodily position herein liberates one from such trauma by reorientation of the hands and arms to a non-pronated, unextended position. This correction involves the upper-arm draping naturally down from the shoulder with the forearm, set at a relaxed forward projecting right-angle, placing the Carpal-ligaments of one's wrists in a non-torqued, neutral position. Because weight of the extended hand/forearm is borne comfortably upon the narrow side (hypothenar-eminence) of the hand, this newly identified reorientation requires no appreciable musculature effort to maintain. The arrangement of keypad controls, with transverse adjustability to user's physique, serves to ameliorate onset occurrence of keyboard associated RMI-diseases. Utilizing visual-reference mirrors adjustable to a user's eye, enables them to readily reference any key-indicia or tracking-mouse hemisphere via convenience of natural mirror-image/reverse-compensated character notation. The system universally interfaces with ordinary electronic keyboard connections, and employs a conventional (albeit split) Qwerty keyboard. It is likewise adaptable to other keyboard formats. Optional accommodation of an Accounting-panel (ten-key; with affixed visual-reference mirror) at the right or left of the keyboard-base, is achieved via a modularly invertible attachment upon either laterally extensile retractable-support member.
Patent EP-0597018-A1 (EP)
Inventor: KLEMKE R ERICH
IPC: A61K31/704
Filed: 1992-07-21
Abstract: Steroidal and non-steroidal glycosides and a method of producing them are provided, wherein aglycon compounds are glycosylated with tri-O-acyl glucal using molecular or ionized halogen as reaction catalyst. The aglycon, which may be a non-steroid or a steroid having a reactive functional group (e.g., -OH, -SH, -COOH, -NH2, -NHR1) such as a cholesterol, is glycosylated, wherein the glycosylation is performed in a single step. For example, a steryl pyranoside is oxidized to the corresponding 7-ketosteryl di-O-acyl-pyranoside, which is selectively reduced to provide the corresponding 7-beta-hydroxysteryl 2,3-dideoxy-alpha-D-erythro-hex-2-enopyranoside. These steroidal and non-steroidal glycosides possess valuable pharmacological properties. In particular, the cholesterol glycoside exhibits a selective cell-destructive activity on malignant cell, in vivo, and is substantially free of side effects on normal cells. The glycosides possess useful pharmacological properties which are the same as their respective unglycosylated aglycons, which properties include a drive-enhancing (stimulating) activity and an anti-inflammatory (immunosuppressive or immunoregulatory) activity.

Abstract: L'objet de l'invention est de développer une soupape coupe-feu garantissant, de façon reproductible, une fermeture étanche. Même lorsque le ressort perd sa force à cause de températures très élevées, la soupape doit rester fermée même sous des coups et/ou des secousses. Afin de résoudre ce problème, on a donné au corps métallique de fermeture (11) une forme sphérique au moins dans la zone d'étanchéité. Son diamètre est tel que l'on obtient un ajustement serré léger avec le diamètre d'un alésage (21) du corps (1) de la soupape lorsque la soupape est fermée. Un deuxième alésage (20) s'étendant axialement par rapport au premier alésage (21) est situé en amont dudit alésage (21) dans la direction du corps de fermeture (11), lorsque la soupape est ouverte. Le diamètre du deuxième alésage (20) s'assemble, avec un jeu, avec le diamètre du corps de fermeture (11). Un guidage conique (19) qui s'élargit dans la direction du corps de fermeture (11) en position d'ouverture est situé entre celui-ci et le deuxième alésage (20). L'invention concerne une soupape coupe-feu avec un ressort de fermeture automatique de canalisations, notamment de canalisations de gaz, du type des soupapes utilisées en amont de robinets de gaz, etc.

Abstract: A sealing device (1) has a sealing chamber (4) which is situated in a part (5) to be sealed off, accommodates the sealing ring (2) and is bounded on its side remote from the thread (3a) by a pinching or cutting edge (8) so that, when the thread (3) of the two parts (5 and 7) to be sealed off is tightened sealing material (9) displaced by the increasing pressure in the sealing chamber (4) emerges radially outwards at the sealing edge (8) and is sheared off, i.e. the sealing chamber is completely filled and the sealing material is put under pressure. To ensure that the resistance to the tightening of the thread (3) between the two parts (5 and 7) to be sealed off does not become too large during this process, leaving a gap (11) between the cutting edge (8) and the opposing surface or end face of the other part (7) under certain circumstances, through which gap the material under pressure in the sealing chamber (4) might creep out over the years, the sealing chamber (4) extends as far as a bottom (12) arranged radially below the core diameter of the thread (3a) of the part (5) in which it is formed and extends axially at least to below the first turn of the other part (7) in the screwed-up end position of the latter and between the first thread turn of the other part (7) and the bottom (12) of the sealing chamber (4) there is a gap (13) for the passage of sealing compound into an interspace (14) situated behind the said gap in the axial direction, the gap being of a width such that the sealing material yields through this gap (13) if there is an excessive increase in the pressure in the sealing chamber (4), allowing the shearing off of sealing material (9) displaced outwards radially through the gap (11) to be accomplished with a reasonable force or reasonable tightening torque and the gap (11) to be completely closed. On the other hand, the gap (13) is sufficiently narrow to ensure that it allows sealing material through only under this severe loading associated with shearing off or pinching off, and the interspace (14) is sufficiently small to ensure that it is likewise substantially or completely filled during this operation. <IMAGE>

Abstract: The method of cleaning atmosphere gas used in manufacturing high-purity fine particles of reactive metals comprises the steps of: letting the moisture existing in the atmosphere gas condense into dew droplets using a cryogenic cooling medium; removing the moisture defined by the dew droplets through dissociation by letting it react with metallic Na that has been brought into contact with the dew droplets; generating a vapor of metallic Na in the atmosphere gas so as to remove the moisture still persisting in the atmosphere gas; further removing through dissociation the moisture still persisting in the atmosphere gas by letting it react with Na vapor that has been generated and dispersed in the atmosphere gas; letting the atmosphere gas cleaned of moisture come into contact with black barium powder; and detecting the presence of moisture in the atmosphere gas through a change in color of the black barium powder (103). The apparatus for practicing the method comprises two devices: one is a Na vapor generator (1) and the other is a trace amount moisture detector (101).
