Abstract: A return waterbox for a heat exchanger, such as a shell-and-tube heat exchanger, is provided. The return waterbox may include an insert configured to direct a fluid flow(s) in the return waterbox. In some embodiments, such as in a two-pass heat exchanger, the insert can be configured to receive water from one portion of the heat exchanger tubes in the first pass and redirect the received water to another portion of the heat exchanger tubes in the second pass.

Abstract: A request for a web page is received and the requested web page is retrieved. The web page is modified to obfuscate a set of form attribute values into a corresponding set of obfuscated form attribute values. The modified web page is transmitted to the requesting device. The modified web page does not include the set of form attribute values in their original form. Form data for the set of obfuscated form attribute values is received from the requesting device. The set of obfuscated form attribute values is deobfuscated thereby revealing the original set of form attribute values. The form data for the set of original form attribute values is further processed.

Contained within the adjusting housing is a carrier extension wherein the carrier extension at one end encases a stationary bushing, the stationary bushing houses an adjusting shaft to provide movement of a rotor assembly axially, and at the opposite end the carrier extension connects to a bearing carrier mechanism.

Abstract: Generally, apparatuses, systems, and methods are described to vent refrigerant vapor from the refrigerant pump line using a vent line, such as during priming of the pump and/or during a startup of the compressor, directed to a relatively reduced volute casing mass of the refrigerant pump, and/or directed to returning refrigerant to an economizer or chiller component other than the condenser.

Abstract: A server receives a piece of data for encryption. The server encrypts the piece of data such that no single key can decrypt the encrypted piece of data and any combination of a first multiple of unique keys taken a second multiple at a time are capable of decrypting the encrypted piece of data. Each of the first multiple of unique keys is tied to account credentials of a different user. The second multiple is less than or equal to the first multiple. The encrypted piece of data is returned.

Abstract: A server establishes a secure session with a client device where a private key used in the handshake when establishing the secure session is stored in a different server. During the handshake procedure, the server receives a premaster secret that has been encrypted using a public key bound with a domain for which the client device is attempting to establish a secure session with. The server transmits the encrypted premaster secret to the different server for decryption along with other information necessary to compute a master secret. The different server decrypts the encrypted premaster secret, generates the master secret, and transmits the master secret to the server. The server receives the master secret and continues with the handshake procedure including generating one or more session keys that are used in the secure session for encrypting and decrypting communication between the client device and the server.

Abstract: Methods and apparatuses for identifying a domain of a command and control server of a botnet are described. Upon receipt of a request to register a domain for a service that includes a proxy server, where the proxy server is to receive and process traffic for that domain if registration is successful, a determination of whether the domain was generated by a domain generation algorithm (DGA) is performed.

Abstract: A server receives a request from a client to establish a secure session. The server analyzes the request to determine a set of one or more properties of the request. The server selects, based at least in part on the determined set of properties, one of multiple certificates for a hostname of the server, where each of the certificates is signed using a different signature and hash algorithm pair. The server returns the selected certificate to the client.

Abstract: A method and apparatus for enabling an HSTS policy for a subdomain of a domain is described. A request for content at a subdomain of a domain is received at a proxy server from a client device over a secure transport. The proxy server determines whether the subdomain is associated with a rule indicating that Hypertext Transport Protocol Strict Transport Security (HSTS) is to be enabled for the subdomain of the domain. Responsive to determining that the subdomain is associated with the rule, the proxy server transmits, to the client device, a first response that includes an HSTS header and which instructs the client device to communicate only over the secure transport for requests for content at the subdomain, wherein the first response includes the HSTS header regardless of whether HSTS has been enabled for the subdomain at an origin server.

Abstract: A server establishes a secure session with a client device where a private key used in the handshake when establishing the secure session is stored in a different server. During the handshake procedure, the server receives a premaster secret that has been encrypted using a public key bound with a domain for which the client device is attempting to establish a secure session. The server transmits the encrypted premaster secret to the different server for decryption along with other information necessary to compute a master secret and session keys for the secure session. The different server decrypts the encrypted premaster secret, generates the master secret, and generates session keys that are used in the secure session for encrypting and decrypting communication between the client device and the server and transmits those session keys to that server.

Abstract: Generally, apparatuses, systems, and methods are described to prime a refrigerant pump by decoupling or shielding from a condenser operation, such as for example the condenser water pump, so that liquid refrigerant can be appropriately sourced from the condenser and/or the evaporator using flow control device(s) such as a source valve on a source line of the condenser and/or on a source line of the evaporator and the control of such valve(s).

Abstract: In one aspect of the invention, a method includes determining an amount of carbon dioxide (CO2) in dialysate flowing through a dialysis system using a CO2 sensor associated with the dialysis system, determining, using a pH sensor associated with the dialysis system, a pH level of the dialysate, and calculating a level of bicarbonate in the dialysate based at least in part on the determined amount of CO2 measured in the gas and the determined pH level of the dialysate.

Abstract: An optical interference coating with reduced back reflectance for 3D glasses based on colour separation has a substantial transmittance at one or more passbands over the visible spectral range in order to view the desired left (right) eye image and a substantial reflectance and absorption at one or more different blocking bands over the visible spectral range in order to block the undesired right (left) eye image while simultaneously reducing the back reflectance of visible light, whatever the source, towards the viewer's eye. The thickness of the absorbing layer material or materials are chosen such that the luminance back reflectance of the coatings is substantially reduced while minimizing the transmittance loss of the filter's desired passbands. The optical interference coating is typically deposited on the concave side of the lens for 3D glasses.
