Abstract: Un lit gonflable pour petits enfants peut être utilisé aussi bien comme siège que comme lit de voyage. Ce lit en plastique comprend différents éléments séparément gonflables, dont un support (1) qui forme une surface sur laquelle le petit enfant est assis ou couché, un rebord (2) qui entoure le support (1) de trois côtés, une paroi extérieure (4) reliée au rebord en forme de coin dans la vue latérale et un deuxième rebord (6) gonflable relié à l'autre bord de la paroi extérieure (4) et ayant la même circonférence que celle-ci. Le rebord (6) forme le corps sur lequel le lit est posé sur le sol et qui assure la stabilité du lit. Afin de relever le support (1) jusqu'à la position assise, on peut serrer le rebord (5) contre le deuxième rebord à peu près en son milieu dans le sens de sa longueur, au moyen d'un lien (5) combiné avec des oeillets. En gonflant plus ou moins la paroi extérieure (4), on peut ajuster l'inclinaison du support (1). Lorsque le lit est renversé de 180~, il peut servir de berceau, la paroi extérieure gonflée (4) sert alors de paravent ou de pare-soleil, alors que le support (1) se trouve dans la position horizontale la plus basse.

Title: Bi-directional elevator governor
Inventor: ERICSON RICHARD J
IPC: G05D13/06
Filed: 1996-04-30
Abstract: An elevator governor rope brake assembly is disclosed for slowing governor rope movement upon the occurrence of unintended movement of an elevator cab. The assembly comprising a governor sheave over which a governor rope passes, with a pivotally mounted brake disposed about its outer circumference on a pivot arm for slowing the governor rope movement. The pivotally mounted brake being capable ofpivoting along a clockwise and counter-clockwise arcuate path, each of the arcuate paths intersecting the outer circumference of the governor sheave at symmetricallocations at an angle sufficient for the pivotally mounted brake to engage the governor rope with sufficient force to slow the governor rope movement. Spring loaded releasing detents are used for initially positioning the pivotally mounted brake vertically. Flyweights on the governor sheave actuate the detents and release the pivotally mounted brake from the initial vertical position upon the occurrence of unintended movement of the elevator cab. The flyweights also provide a force to the pivotally mounted brake in a direction consistent with the governor rope's movement, thereby urging the pivotally mounted brake to arc in the desired braking direction.

Abstract: On the Internet, and in particular the World Wide Web (WWW), there are problems associated with the dissemination of information to large number of people that stem from the highly distributed nature of the network. Such dissemination currently can be carried out by using electronic mail, which is rather intrusive when such information is not solicited by the receiver, or through publishing the information on very popular Web sites, which limits such dissemination to visitors of the Web site. In this invention, which applies to an inter-networking environment, such as the WWW, the client software program is used to disseminate information stored on a central server by displaying such information in conjunction with information retrieved from an arbitrary server in the normal course of using the client software. The method disclosed here makes it easy to reach millions of people in a manner synonymous with broadcasting albeit in a subtle way.

Abstract: An adaptor (36) processes and transfers data from a computer (12) to a printer (16). The data is divided by the computer (12) into blocks of non-repeated (different) and repeated (identical) data elements. The adaptor (36) receives the blocks of non-repeated data elements from the computer (12) and re-transmits them to the printer (16) without alteration. Rather than transmitting a block of repeated data elements per se. the computer (12) transmits a number of alternating high and low strobe signals that are equal to the number of repeated data elements in the block. The first repeated data element is latched by the adaptor (36), and then repeatedly transmitted to the printer (16) in response to each respective alternating strobe signal.
