Title: Two coil rotary actuator for a disk drive
Inventor: YOSHIDA TAKESHI
IPC: G11B21/08
Filed: 1994-02-18
Abstract: A disk drive comprising a carriage 3 rotatable by first and second driving coils 5A, 5B about an axis that moves a head 1 radially across a disk 13. The angle between a line connecting the center of the first driving coil 5A, and the center of the carriage pivot shaft 4 and a line connecting the head 1 and the center of the carriage pivot shaft is set to be not greater than 90 degrees while the angle formed between the first and second driving coils 5A, 5B about the center of the carriage pivot shaft 4 is within the range of 100 degrees to 150 degrees, whereby a reduction in the size and thickness of the apparatus can be realized. A magnet-yoke assembly, is mounted to a base 12 by sheet springs 8A - 8D and reaction-force damping members 10A, 10B interposed therebetween so that the magnet-yoke assembly 6A, 6B, 7A - 7G is independent from and infinitesimally rotatable relative to the base 12. The provision of the two driving coils 5A, 5B and the reaction-force damping members 10A, 10B effectively prevents the carriage pivot system and the disk spindle from being excited by a reaction force, and thereby assures high-speed and highly-accurate head positioning. <IMAGE>

Title: Method for operating an adjustable hydrostatic pump
Inventor: STRENZKE HILMAR
IPC: F04B49/08
Filed: 1994-04-22
Abstract: In a method for operating an adjustable hydrostatic pump (1) the width of opening of a throttle (4) in a delivery line (2) leading to a consuming device (3) is adjusted, the pressure drop at the throttle (4) is measured, communicated to a load-sensing controller (8) and the displacement of the pump (1) is adjusted by the load-sensing controller (8) to a value at which the delivery pressure of the pump (1) exceeds the pressure at the consuming device by a pressure difference (delta p) determined by the system. In order to permit good fine control for low speeds of movement of the consuming device and maintenance of the load-sensing control at high speeds of movement of the consuming device with minimal loss of power, the speed of movement of the consuming device (3) is determined as a set value and depending on it the pressure difference (delta p) and the width of opening of the throttle (4) are controlled in combination. Here, a certain pressure difference (delta p) and a certain width of opening are automatically associated with one another. <IMAGE>

Title: Photometric instrument with optical fibres for analyzing plural remote samples
Inventor: CAHILL JERRY E
IPC: G02B6/42
Filed: 1994-06-20
Abstract: In a spectrophotometer, each of a plurality of source optical fibers (58) is selectively receptive of source radiation and carries the radiation to a corresponding selected liquid sample cell (68). A corresponding return optical fiber (72) returns transmitted radiation from the sample to a polychromator. For selecting a sample, a switching member (100) holds exposed ends of the optical fibers on a circle coaxial with an axle for rotating to selected positions. Respective optical trains in the instrument direct radiation into and out of the selected pair of fibers. The diameter of a source aperture (90), the spacing of the aperture from the radiation source (12), and the source area (96) define a source etendue. The optical fibers have a fiber etendue substantially the same as the source etendue. <IMAGE>

Title: Numbering box in a printing press
Inventor: RUF BERND
IPC: B41F11/00
Filed: 1995-10-25
Abstract: A numbering box (1), which is mounted in a printing press, has a numbering-box shaft (2) for holding numbering apparatuses, an inking apparatus (3) with plate-inking roller (4) and a switching device (5) for moving the housing (14) of the shaft (2) towards or away from the press. Such a numbering apparatus is to be of such design that overinking of the numbering apparatus and wear and tear on the plate-in king roller are prevented in a simple and easy-to-use manner. This is achieved in that the numbering box (I) is situated on rails (6) held in the printing-press housing of the printing press and in that the numbering box (1) is adapted, through displacement in the telescopic rails (6), by means of a switching shaft (8) and lever (9), to be brought into and out of engagement with the impression cylinder (7). A mechanism causes the simultaneous engagement or disengagement of the inking apparatus (3) with respect to the numbering-box shaft (2). <IMAGE>
Patent GB-2310760-A (GB)
Title: Vacuum switching device
Inventor: RAND JOHN
IPC: H01H33/662
Filed: 1996-02-27
Abstract: A vacuum switching device incorporates an electrically conductive shield 30 which extends beyond at least one end of a ceramic insulator housing 20. The result of this is reduced electrical stress particularly at the triple point 41 connecting the relevant end of the insulator and an end-ring 33, leading to a reduction in the length requirements for the switching device. Further, because the deposition of metal vapour onto the ceramic wall is virtually eliminated, the device does not have to be over-rated to take into account the degradation in its operating parameters that would occur during the lifetime of the device if the shield were of conventional design.

Patent GB-2305081-A (GB)
Title: Reducing messaging in a TDMA communications system
Inventor: SPEAR STEPHEN L
IPC: H04L7/04
Filed: 1996-08-30
Abstract: A TDMA communication system uses an enhanced access burst 300. The enhanced access burst has an additional logical information field 311, or alternately, one of a set of possible synchronising sequences indicative of supplementary information. Upon receipt of a system parameter indicating an enhanced access burst capability, a communication unit (105 in figure 1 not shown) sends an appropriate enhanced access burst 300 with the increased information. A reduction in system messaging is thus achieved, for example, by avoiding the need to send the supplemental information via subsequent bursts. The method is particularly suited for transferring the shorter types of data bursts in GSM systems.
Patent GB-2304876-A (GB)
Title: Control of water flow in a condensing boiler heating system
Inventor: LEISHMAN JAMES
IPC: F24D3/08
Filed: 1996-09-04
Abstract: Water flow is directed in a heating system with a condensing boiler such that on start up substantially all the flow of primary water from the boiler is used to heat water in a secondary store 10 via a heat exchanger 20 until a first degree of heating has occurred, then dividing the flow of water between the secondary water store and a space heating system and finally, after a second degree of heating, directing substantially all the flow of primary water to the space heating system. The return water is passed through a heat exchanger with the flue gases and the unit operates most efficiently when the return water is cool enough to condense the steam in the flue gas; the first degree of heating may be when the return water is too warm to condense the steam. A heat sink may be provided either in the secondary store or the primary water circuit to help reduce the temperature of the return water.

IPC: H03B1/00
Filed: 1998-01-21
Abstract: A transmitter vco includes nodes for receiving a band selector voltage for altering the base-emitter capacitance of a transistor to enable the vco to act as an oscillator in the appropriate band and for altering the resonator capacitance to change the resonant frequency of the oscillator and to enable oscillation in different frequency bands for dual mode communication devices e.g. radiotelephones. The base emitter circuit includes a resonant circuit formed by a capacitor 306 and a stripline inductor 304. Frequency band of operation may be changed by applying a band selector voltage to bias a diode 308 on and to connect a capacitor 310 across the capacitor 306. Application of the band selector voltage may also connect a series combination of capacitor 322 and a varactor 327 in parallel across a combination of a capacitor 324 and a varactor 328 in the emitter path. A cellular telephone including the voltage controlled oscillator is described with regard to figure 1 (not shown).
