Title: Control of ph during bordetella growth
Inventor: HERBERT ANDREW
IPC: A61K39/10
Filed: 1994-12-15
Abstract: Bordetella species, such as Bordetella pertussis, is grown under aerobic conditions in a liquid culture medium containing nutrients for such growth.   Enhanced cell density  and  antigen  production  are  achieved  by continuously determining the pH of the culture medium and, in response to such determination, simultaneously feeding, as required,   (a) an acid, usually a mineral acid,  such as hydrochloric acid,  phosphoric acid or sulfuric acid, in a concentration sufficient to maintain the pH of the culture medium within a predetermined range of values, usually about pH 6.8 to about pH 7.3, and (b) a nutrient medium containing organic carbon and organic nitrogen, usually a neutral salt of an amino acid, such as monosodium glutamate, an amino acid, such as glutamic acid, or a mixture thereof.

Title: User interface-to-terminal emulation-driven operational support system translation mechanism resident in craftsperson's portable test and communications device
Inventor: SCHILLACI ONOFRIO
IPC: H04L69/40
Filed: 1995-11-14
Abstract: A user interface for a craftsperson's portable signal processing and communication unit incorporates an intermediate translating mechanism, termed "middleware", that is effectively invisible to an operational support system ((OSS), such as an AT&T CAS, and is operative to generate a text/graphics interface having one or more functionall "buttons". The buttons are displayed on the portable unit's contact-sensitive display screen and are invoked by the craftsperson placing a contact pen against the button. When a button is invoked, the middleware interface generates the appropriate alpha-numeric or other code used by the operational support system to represent the invoked function. Such an implementation of the user interface frees the craftsperson from having to be familiar with OSS codes, or look up in a separate database the required alpha-numeric code formats, employed by such support systems.

Title: Steerable rotary drilling systems
Inventor: BARR JOHN D
IPC: E21B7/06
Filed: 1996-02-23
Abstract: A steerable rotary drilling system comprises a bottom hole assembly which includes, in addition to a drill bit, a modulated bias unit and a control unit including an instrument carrier which is rotatable relative to the bias unit. The bias unit comprises a number of hydraulic actuators spaced apart around the periphery of the unit, each having a movable thrust member which is displaceable outwardly for engagement with the formation. Each actuator can be connected, through a rotatable control valve, to a source of drilling fluid under pressure, the control valve comprising a first part, rotatable with the instrument carrier, which co-operates with a second part which is rotatable with the bias unit. Means are provided to roll stabilise the instrument carrier so that relative rotation between the bias unit and instrument carrier, as the bias unit rotates, causes the valve to operate the actuators in synchronism with rotation of the bias unit so as to apply a lateral bias thereto. In order to neutralise or reduce the net bias applied to the bias unit the instrument carrier may be rotated in various modes instead of being roll stabilised, e.g. it may be rotated at a constant slow speed relative to the bias unit, or at a significantly faster rate so that the actuators do not have time to operate fully. The angular velocity of the carrier may also be varied during its rotation, according to various formulae, in order to vary the net bias. The net bias may also be varied by alternating different modes of carrier rotation.
