Abstract: A computing device provides enhancement of the capabilities of text messaging applications that execute on user devices. The computing device includes a processor that receives a text message via a network from a user device, the text message including a character representation of a product bundle of a merchant. The processor determines bundle data for the product bundle by referencing a database using the character representation. The processor provides one or more text messages via the network to the user device with transaction data including the bundle data, payment data, and shipping data. The processor receives a text message via the network from the user device confirming the transaction data. The user may use text commands presented by the computing device or natural language conversation in the text messages to the computing device to modify the transaction data and perform other ecommerce actions.

Abstract: A vacuum system non-return valve has a baffle for extending across a flow path The baffle has an aperture, a perimeter of the aperture having a valve seat. The valve also has a valve member having a protrusion extending from a surface configured to mate with the valve seat, the protrusion extending through the aperture; wherein the protrusion includes a retaining portion extending outwardly from the protrusion and configured such that the retaining portion cannot pass through the aperture. The valve member and aperture are configured such that the valve member obscures the aperture and seals with the valve seat to impede a flow of fluid from an outlet end to an inlet end in a closed position and is displaceable in use to move away from the valve seat and allow a fluid flow from the inlet end to the outlet end in an open position.

Abstract: This disclosure describes systems, methods, and computer-readable media related to retargeting online advertisement campaign recommendations for advertisements with multiple items or services. Bids may be based on a combined advertisement creative comprising two or more items or services. Dynamically selecting multiple items at bid time using a retargeting model to determine a potential revenue generation amount associated with an event may increase the probability of a conversion event based on the creative that includes the selected items. In some embodiments, a machine-learned retargeting model may be used to select multiple items to be displayed in an advertisement. The retargeting model may be applied to items that were previously viewed by the consumer and may determine a value for each of the items using factors. A bid may be calculated for each of the selected items using the values determined by the retargeting model.

Abstract: A pump cooling system may include a cooling body configured to be fitted to a pump housing to receive heat from the pump housing via a heat conducting path between the cooling body and pump housing. The cooling body may have a passage through which, in use, a cooling fluid is passed to conduct heat away from the cooling body. The pump cooling system includes a cooling control mechanism configured to provide a gap in the heat conducting path at pump operating temperatures below a predefined temperature so heat conduction from the pump housing to the cooling body is interrupted.

Abstract: In situations where a vacuum system is suddenly overloaded, there is a risk of mechanical damage being sustained, for example, bearing damage, gear slippage or rotor and/or stator collisions. Sudden overloads can also lead to electrical damage, for example, over-currents or power surges. Therefore a pressure regulating apparatus is provided for use in a vacuum pumping system having an inlet, an outlet and a conduit interposed between, and in fluid communication with, the inlet and the outlet, wherein the cross-sectional area of the conduit is greater than that required to meet the conductance requirements of the inlet and the outlet.
