Title: Expression of polypeptides in yeast
Inventor: HITZEMAN RONALD A
IPC: C12N1/16
Filed: 1982-02-24
Granted: 1987-06-11
Abstract: In order to make a yeast strain capable of expressing a desired polypeptide (e.g. leukocyte interferon D) which it does not normally make or use, it is transformed with an expression vector. This is obtained by producing a transfer vector which has respective origins of replication and phenotypic selection genes derived from both bacteria and yeast, and inserting into it DNA fragments: (i) coding for the desired polypeptide and (ii) comprising a yeast-derived promoter. The insertion is effected so that 'start' and 'stop' signals are provided, and these and the promoter can control expression of the polypeptide, and so that the replication origins and phenotypic selection genes of the transfer vector are still functional. Thus the expression vector and its precursors can replicate, and their presence can be recognised, both in yeast and bacteria. Bacteria are used for amplification. The yeast-derived phenotypic selection gene may complement a mutation carried by the strain to be transformed.

Granted: 1991-12-12
Abstract: The test piece is carried on a rigid slip plate, driven in two coplanar axes simultaneously by cantilevered shaker armatures. Slip plate movement is constrained into the driving axes.  Two vibration shakers are separately coupled to the slip plate, which can be held for universal sliding on a support block.  Pivot movements are converted to linear motion by a torsionally stiff flexure support sleeve. The shakers are placed angularly about a horizontal locus of slip plate two-axis vibration.  The shakers have an armature for driving the slip plate supported within a fixed field coil. The armature can have lateral as well as longitudinal freedom within the field coil, the armature comprising a rectangular section wire winding.  The vibrating machine allows screening of mechanical or electrical components for defects.

Abstract: A coin routing gate comprising a pivotally mounted gate member (50) which has a first position from which it can be deflected by a moving coin (102) to a second position to permit the coin to take one path (R), and electrically energisable retaining means (60) which is selectively operable to retain the gate member in its first position to cause the coin to take another path (A), characterised in that the gate member when in its first position provides part of a coin track (37,50) on which coins travel on edge, the gate member is deflectable from the first position to the second position by the weight of a coin, and the gate member when retained by the retaining means in its first position is not deflected by the weight of a coin so that the coin continues to travel on the coin track. No power is required to route the coin to said one path, because this is done solely in response to the weight of the coin. The power required to route the coin to the other path is only that required to retain the gate member in its first position and this can be made extremely low. Thus, the power consumption of the gate can be made very low so as to suit it for low power applications such as coin operated telephones.

Abstract: A system and method for detecting the influence of selected forces on an interferometer over an extended dynamic range. One presently preferred embodiment is disclosed for detecting rotation of an interferometer. In this embodiment, an open-loop (14), all-fiber-optic gyroscope provides an output signal comprising the phase difference of two light waves which are counterpropagating within the gyroscope, and which are phase modulated (38) at a selected frequency. The phase difference of the light waves is influenced by the rotation rate of the interferometer. The output signal is amplitude modulated (156, 300) at the phase modulation frequency to transpose the optical phase shift into a low frequency electronic phase shift, which is measured using a digital time interval counter (166, 168, 174, 178, 304, 308). A linear scale factor is achieved through use of this system and method.
