Abstract: A drink dispensing syphon package is disclosed having a syphon head (304) configured to fit over neck (350) of a bottle (352) in sealing relationship. A lever (340) is mounted to exterior surface (360) of body (362) by breakaway filaments and a spring strip. In use, the user pulls upward on lever (340) to rupture the filaments. The strip (230) pivots an end of lever (340) through opening (342) in body (362) and through actuating rod (348). Actuating rod (348) is attached to interior surface of the body (362) by a resilient diaphragm. The invention relates to apparatus for and a process of filling such a container which uses a permanent syphon filling head for cooperation with a valve in the necked opening of the container when the container is supported in a pivotable cradle. A source of liquid under pressure for supply to the container is connected to the filling head as is means for removing gas from within the container.

Abstract: The method is based on cooperation between a private branch exchange and a data processing system. From the latter it is possible to transmit, for example, control data for an automatic connection sequence between two terminal devices (T1, Te or T1, Tn) to the private branch exchange (NA). With sequences in the exchange which are initiated by the data processing system, at least some of the signals transmitted between these installations are constructed in such a way that the user data section of a signal also comprising at least a control data section as well includes both the information necessary for a process to be initiated thereby and additional information on one or more switching sequences or other sequences to do with this process. In the case of the connection set-up controlled by the data processing system it is possible, for example, for a signal to include in its user data section information on the respective call durations of the individual terminal devices between which the connection is to be established. Furthermore, it may also contain information on the type of the necessary acknowledgements. Such a combination dispenses with the need for signals to be additionally transmitted, as a result of which, in particular for special applications such as for example the alarm call service, the necessary data throughput does not lead to the data channel being overloaded. <IMAGE>

Abstract: The machine has at least one indicating device with an electro-mechanically driven symbol holder, rotating behind a transparent window, and showing at least one symbol to represent the result of the play and usually a combination of symbols which are controlled in a random fashion. The indicating device consists of a carousel, a rotating wheel which carries a series of cards or displays, hinged on the hub, and which flip over as the wheel rotates. The wheel is turned in one direction only and faces the window, with a projection at the top to hold a card for some instants, but then the card, after remaining visible in the window for a few seconds, is forced past the projection for the next card to be held.  Each card has a symbol represented on it. The whole arrangement, with driving gears and so on, including the card carousel, is contained in a housing and the design caters for a series of such arrangements, each with a carousel, housed in a succession of cabinets, all part of one console.

Abstract: Process for increasing the rate of production of carbon dioxide, ethanol and other fermentation products such as citric acid, produced by yeast such as Saccaromyces cerevisiae during fermentation and decreasing biomass production by regulating the rate of glycolysis indirectly through changing the energy balance of the cell, i.e. by reducing intracellular ATP levels. Modifications for so altering the glycolysis rate involve the use of either a regulated ATP hydrolysis within the cell or a regulated leakage of ATP from the cell. This invention encompasses several ways for altering the yeast ATP level including (a) engaging futile metabolic cycles to increase ATP consumption; (b) using an altered exocellular acid phosphatase so that it becomes intracellular to increase intracellular ATP hydrolysis; (c) using a drug which uncouples the plasma membrane ATPase thereby consuming an abnormally high level of ATP; and (d) using a drug which allows the release of ATP from the cell to lower the intracellular ATP level. This invention further encompasses regulating the genetic modifications described in greater detail herein. By these means, such modifications may be turned off during growth of the yeast on a commercial scale, and then turned on before or during, and preferably before or at a very early stage of, the dough-rising phase.

Abstract: A changing device for the screw cylinder of an injection molding machine. The screw of the screw cylinder is in releasable coupling connection with a drive unit of the machine. For releasing and uncoupling the coupling connection, the screw cylinder including screw can be displaced relative to the injection molding machine essentially transversely of the longitudinal direction of the screw cylinder. Two hydraulic cylinders are arranged spaced apart next to each other symmetrically and parallel to the longitudinal center plane of the injection molding machine. The two cylinders are connected to each other by means of a transverse member. A free space extending forwardly from the drive unit is defined by the two hydraulic cylinders and the transverse members. The free space forms an alignment seat which is open towards the front and towards the back and a longitudinal side. In the coupled position, the screw cylinder is fixable and lockable to the drive unit in this alignment seat. The free space forming the alignment seat of the changing device is open toward the bottom, so that the transverse member which connects the hydraulic cylinders acts on the upper longitudinal side of the hydraulic cylinders.
