Title: System zum Aufbau von Vorrichtungen zum Aufspannen von Werkstücken
Inventor: WITTE HORST
IPC: B23Q3/10
Filed: 1986-10-06
Abstract: Das System zum Aufbau von Vorrichtungen zum Aufspannen von Werkstücken auf Werkzeugmaschinen in definierter und reprouzierter Lage weist eine Grundplatte l auf, die auf einem Maschinentisch oder dergl. aufsetzbar ist. In der Grundplatte sind in regelmäßigen Koordinatenabständen angeordnete Paßbohrungen ausgebildet. Weiterhin sind in der Grundplatte in einer Ebene senkrecht zu den Paßbohrungen 5 vorzugsweise sich kreuzende Querbohrungen 6 ausgebildet, deren Durchmesser demjenigen der Paßbohrungen entspricht. In die Querbohrungen und auch in die Paßbohrungen werden Mutternteile für die Paßschrauben eingesteckt, um Aufnahmeteile an der Grundplatte zu befestigen. Der Querschnitt der Mutternteile entspricht demjenigen der Quer- und Paßbohrungen. Die Aufnahmeteile sind vorzugsweise nach dem gleichen Prinzip mit Quer- und Paßbohrungen versehen. Da das Rastermaß der Dicke der Grundplatte und der Aufnahmeteile entspricht, und die Außenabmessungen durch das Rastermaß teilbar sind, ergeben sich in Verbindung mit den kreuz und quer verlaufenden Paß- und Querbohrungen, deren Durchmesser vorzugsweise dem halben Rastermaß entspricht, vielfältige Kombinationsmöglichkeiten.

Abstract: A macroscopically expanded, three-dimensional fluid-handling polymeric web having first and second surfaces located in substantially parallel planes which are remote from one another. The web includes a multiplicity offluid-handling capillary networks of macroscopic cross-section for rapidly transmitting fluids which are dynamically deposited on the first surface of said web to the second surface of said web using the dynamic and gravitational head of the fluid as a primary driving force. Each of the macroscopic cross-section capillary networks originates as an aperture in the first surface of the web and has a continuously interconnected sidewall extending in the direction of the second surface of said web. The continuously interconnected sidewall terminates to form at least one aperture in the second surface of said web, whereby the bulk of the dynamically deposited fluid is transmitted from the first surface to the second surface of said web by the macroscopic cross-section capillary networks. The first surface of the web in which the macroscopic cross-section capillary networks originate further includes a multiplicity of fluid-handling capillary networks which are substantially smaller in cross-section than the macroscopic cross-section fluid-handling capillary networks. The smaller fluid-handling capillary networks exhibit a degree of capillary suction sufficient to transmit static fluid contained on the surface of objectswhich contact the first surface of said web generally in the direction of the second surface of said web by capillary attraction. In a preferred embodiment the smaller fluid handling capillary networks are oppositely oriented from the macroscopic cross-section capillary networks to provide improved visual and tactile impression as well as to enhance the volume of dynamically deposited fluid which flows into the macroscopic cross-section capillary networks.

Abstract: A composition for forming a hydrophilic film on aluminum comprises an alkali silicate, an inorganic hardening agent and a water-soluble organic high-molecular-weight compound. The composition is useful for aluminum fin materials for producing heat exchanger fins, aluminum products such as aluminum heat exchangers comprising fins and tubes in combination, and materials of such products. The high-molecular-weight compounds effectively prevents the alkali silicate from giving off a cement odor and also sustains over a prolonged period of time the hydrophilic properties of the film prepared from the alkali silicate and the hardening agent. The composition forms hydrophilic films releasing no cement odor and retaining sustained hydrophilic properties over a long period.

Abstract: Method for charging Ni-Cd batteries with a repetitive and alternating sequence of direct current charging and discharging periods. Steep current pulses are superimposed on the respective direct currents which have a sense equal to that of the direct current and intensity exceeding respective predetermined levels. Owing to the effects of such alternating and repetitive current pulses the surface distribution of the electrodes will change after some time and the electrode surface gradually become homogeneous. The periodically repetitive steep current pulses can be used during the whole charging process and they have beneficial effects for the charging of new batteries as well. The current changes at the beginning of the respective periods should be at least seven times as high as one tenth of the ampere-hour capacity of the battery.

Abstract: The present invention relates to a substrate material having a decreased retentive capacity for use as a carrier for aerosol forming materials in smoking articles which smoking articles are capable of producing substantial quantities of aerosol, both initially and over the useful life of the product, without significant thermal degradation of the aerosol former and without the presence of substantial pyrolysis or incomplete combustion products or sidestream aerosol. Thus, the substrate material of the present invention when used with preferred smoking articles is able to provide the user with the sensations and benefits of cigarette smoking without burning tobacco. In addition, the article may be made virtually ashless so that the user does not have to remove any ash during use. 
     Preferred smoking articles which employ the substrate material of the present invention have a short combustible carbonaceous fuel element, alumina or carbon substrate modified in accordance with the present invention bearing an aerosol forming substance, an efficient insulating means, and a relatively long mouth end piece. The fuel element is provided with a plurality of longitudinally extending passageways which act to control the heat transferred from the burning fuel element to the aerosol generating means, thus preventing the thermal degradation of the aerosol former.

Abstract: The present invention relates to a switching technique for packet Frequency Division Multiplexed (FDM) communication systems. In the present system, each of N system users is assigned (a) either a separate fixed one of N transmit frequency channels or a selected free one of L transmit frequency channel for communications to a head-end FDM channel switching means (10), and (b) a fixed assigned separate one of N receive channels for communications from the head-end FDM channels switching means. At the FDM channel switching means, all FDM channel signals received from the system users are directed into separate paths (21) through the switching means. The signals in each path are demodulated (23) to baseband, and a destination address in each packet is detected (28) to determine where each packet is to be sent. Each path in the switching means is hard-wired therethrough to an associated transmitting oscillator (29) which is frequency tuned, by means of the detected destination address, to the unique frequency channel of the user or the external network which is the desired destination of the packet. Thus, switching of a packet signal is accomplished without ever connecting or disconnecting wire lines.
