Abstract: A cryogenic cooling system is provided comprising a primary insert (118) and a demountable secondary insert (128). The primary insert (118) comprises a plurality of primary plates (111, 112), each primary plate having a primary contact surface, and one or more primary connecting members (117) arranged so as to connect the plurality of primary plates (111, 112). The demountable secondary insert (128) comprises a plurality of secondary plates (121, 122), each secondary plate having a secondary contact surface, and one or more secondary connecting members (127) arranged so as to connect the plurality of secondary plates (121, 122) such that the secondary insert (128) is self-supporting. One or more adjustment members are configured such that, when the secondary insert (128) is mounted to the primary insert (118), the adjustment members cause the primary and secondary contact surfaces of the respective primary (111, 112) and secondary plates (121, 122) to be brought into conductive thermal contact.

Abstract: A computing system includes a computer network, a server connected thereto, and a client device for communicating with the server over the computer network. The client device runs an application shell software module providing a dynamically configurable application in a piecemeal manner by individually downloading and running a plurality of software components that are individually stored on the computer network and downloaded/run when needed. The server receives a request for available software components from the application shell software module, controls a search of an index for available software components and transmits a response to the application shell software module providing details of available software components.

Abstract: A well depth measuring device that collects depth data so operators do not have to manually record the data in the field and then again into a computer. The well measuring device is attached to the well head. A rotary encoder rotates as a probe/sensor is lowered into the well via a longitudinal strip of tape. The rotary encoder sends pulses to electrical circuitry and a handheld computer that stores longitudinal information. The stored information can be easily transferred to other computers and databases.

Abstract: A measuring cutter for food in block form, such as butter. The cutter has a blade with measurement marks spaced from one another in a first direction, and a cutting edge perpendicular to that direction. The food block is aligned with a measurement mark, and the cutter is pivoted about the cutting edge and thrust downwardly so as to sever a predetermined quantity of butter from the bar in a single stroke. Preferably, the cutting blade is as wide as or wider than the width of the block being cut.

Abstract: Apparatus for labelling a stereophonic signal includes a plurality of notch filters having selected center frequencies to form notches at the selected frequencies in the channels of a stereophonic audio signal. Code generating components produce a coded label signal in the form of one or more code words, with the code being formed of selected signal bursts at the selected frequencies. The coded label signals are inserted into both channels of the audio signal, in the notches formed by the notch filters. The code signal amplitude bears a predetermined relationship to the audio signal amplitude in each channel.
