Title: Impact dot matrix printer in which print wires can be reconfigured from draft (non-interlaced) to near letter quality (interlaced) arrangements
Inventor: YAMAKAWA YUICHI
IPC: B41J2/255
Filed: 1992-11-16
Abstract: The forward ends of the printing wires are supported in two generally parallel columns by two superimposed guide plates 3 and 4. As (separately) shown (Fig 4) one guide plate 3 supports the wires of the right hand column in respective apertures 3a, and those of the left hand column in a single vertically elongate slot 3b. The arrangements for the plate 4 are similar, but with the disposition of apertures 4b and slot 4a reversed. With such an arrangement one of the columns can be vertically displaced by vertical movement of plate 3 to either bring the wires thereof into horizontal registry with the wires of the other column (draft quality printing) or into a position had a dot width out of registry with the other column (near letter quality printing). As described the printing head is mounted on a carriage which reciprocates across the machine frame during printing, and a cross link on the carriage is arranged to engage its ends against respective end stops on opposed sides of the machine when the carriage is traversed beyond the normal range of printing motion. Movement of the link causes raising or lowering of plate 3 in accordance with which end stop last abutted a link end. <IMAGE>

Title: AC-DC-AC converter, particularly for fluorescent lamps
Inventor: SUZUKI SHIGESADA
IPC: H02M3/335
Filed: 1992-11-18
Abstract: In order to avoid harmonics in the current I1 drawn from AC supply 21 and to avoid use of large-size components, the D C supply for high frequency inverter 30 includes a rectifier 23 charging a capacitor 26 so as to provide a pulsating D.C. voltage VC2 thereon, a capacitor 29 charged to a voltage VC6 below the peak value of capacitor 26 voltage, and means to discharge capacitor 29 in an oscillatory or pulsating manner during those portions (TB), (Fig 3), of each half cycle of A C supply 21 during which the capacitor 26 voltage is below the voltage of capacitor 29. An inductor 28 may form an oscillating discharge circuit A in association with capacitors 26, 29 with the oscillations being synchronised with the ON/OFF timing of inverter transistor 32. Alternatively, a discharge FET, (Fig 17), may operate in antiphase with inverter transistor 32. Capacitor 29 may be charged by a tertiary winding 31c on inverter transformer, by current flow through inverter transistor 32, (Fig 9), or two capacitors (291), (292), (Fig 10), may be charged in series from rectifier 23 and discharged in parallel. A MOSFET (69), (Fig 12), may switch a capacitor (68) in parallel with capacitor 26 in a manner such that the peak voltage thereon does not vary with variations in the peak voltage from rectifier 23. A transistor (Q11), (Fig 15), parallel to a diode 25 may be turned on during those periods (TA), (Fig 16), when capacitor 26 voltage is higher than capacitor 29 voltage so that the resonant voltage of inverter circuit 31 a, 33 is not superposed on capacitor 26 voltage at such times. Inverter transistor 32 may be controlled by a circuit (87), (Figs 20, 23), responsive to the output voltage and current of rectifier 23 so as to vary the inverter frequency such that the current drawn from supply 21 remains substantially sinusoidal. Circuit (87) may be arranged to control the frequency only during discharge of capacitor 29, (Fig 24). <IMAGE>

Title: Hollow needle for use in spinal anaesthesia
Inventor: AGLAN MAGDY YASSIN
IPC: A61M5/32
Filed: 1992-12-11
Abstract: The needle has a closed tip 12 and a lateral orifice 14 close thereto communicating with an internal passage 11 through the shank, the orifice being equal in area to the internal cross-sectional area of the shank. This serves to maintain ideal flow characteristics through the needle and has the added advantages of increasing the strength of the needle tip and minimising the possibility of inadequate spinal anaesthesia. The needle has an atraumatic tip i.e. has no cutting edges, and will minimise damage to the dura, pushing the fibres aside so that they may close naturally with less spinal fluid leakage. <IMAGE>

Title: Combined check and pressure-relief valve
Inventor: MORAN KEVIN PATRICK
IPC: B01D35/147
Filed: 1993-07-09
Abstract: A combined check and pressure-relief valve comprises a sleeve 24 slidable in a housing 17 to cover or uncover ports (23, fig. 2). The sleeve is spring biassed to cover the ports, but can be pressed down by an actuator member 34 to uncover them. The valve is mounted in a filter assembly, flow normally passing through an inlet 12, a filter 15, the sleeve 24, and an outlet 13. If flow reverses, the actuator member 34 moves to shut off one end of the sleeve, thus preventing reverse flow through the filter. Excess pressure in either direction will depress the sleeve, exposing the ports and allowing flow between the inlet and outlet, bypassing the filter. The actuator member can be guided by means of a stem 35 sliding in a guide member 37, which snap fits onto the housing 17. <IMAGE>

Patent GB-2274637-A (GB)
Title: Non-refilling devices
Inventor: HAMILTON BARRY PATON
IPC: B65D49/06
Filed: 1994-01-17
Abstract: In a non-refilling device for use in container outlets such as the necks of spirits bottles, to prevent un-authorised refilling thereof, at least two components of a one-way valve means are formed of a different material giving markedly differing resonance characteristics to each. For example, a ball weight 5 may be of a zinc alloy, a valve member 12 of polycarbonate plastics material and valve seating portion 16 of silicon rubber. Thus an attempt to cause the valve 12 to lift from its seating 16 by applying a vibratory force equal to the natural resonance of the valve means will be unsuccessful since it will be found impractical to identify the natural resonance. <IMAGE>

Title: Disposable diapers of the pants type
Inventor: SUEKANE MAKOTO
IPC: A61F13/15
Filed: 1994-05-19
Abstract: The diaper 1 comprises a liquid absorbent core 4 sandwiched between a liquid-permeable topsheet 2 and a liquid impermeable backsheet 3, forming front and rear bodies 5, 6 of the diaper 1 and a waistband which is formed by bonding together, under heat and pressure, wing-like portions 21 of the front and rear bodies, so that the faces of the topsheet along said wing-like portions are opposed. Normally the topsheet 2 has a higher melting point than the backsheet 3 and this causes uncomfortable and unsightly surfaces at the bonded areas. Thus sheets 3A having a melting point higher than or equal to that of the topsheet are attached to backsheet in each of said wing-like portions 21 to prevent the formation of such surfaces. Alternatively, sheets (2A, Fig. 6A) may be attached to the topsheet, or sheets (2A, 3A, Fig. 6B) may be attached to both the backsheet and topsheet, to provide the desired relative melting points at the wing-like portions. <IMAGE>

Title: Chart recording apparatus
Inventor: ROWLANDS STUART
IPC: G01D15/24
Filed: 1995-04-07
Abstract: A chart recording apparatus which is used for providing a permanent trace or record on a recording medium or chart to show the variations of a measured parameter with time comprises a pivotally movable arm which usually carries a pen and a drive arrangement to drive the recorder arm pivotally. The drive arrangement comprises worm gearing having a worm 7 arranged to mesh with a correspondingly threaded or tooth-form curved portion of a worm follower 6 which is pivotally mounted and operatively coupled to the recorder arm 5. Driving the worm effects pivotal movement of the worm follower which causes pivotal movement of the recorder arm. The worm gearing enables a high gear ratio to be achieved between a drive motor 8 and the recorder arm 5 to provide a high resolution and smooth action using only two gears. This is stated substantially to eliminate backlash.
