Abstract: POLE VAULTER'S LANDING CUSHION                 Abstract of the Disclosure A notch or cutout configuration for a pole vaulter's landing cushion provides increased protection for the athlete while avoiding interference with bending of the vaulting pole.  The top of the notch is broad at the pole planting region and relatively narrow at a more forward region.  In the preferred form, the base of the notch is narrowing the pole planting region and broadens towards the front of the cushion to conform with the outline of a vaulting box, the sidewalls and back wall of the notch being inclined outwardly in the pole planting region while the notch sidewalls in the more forward region are vertical.  In addition to providing more extensive cushioning adjacent the vaulting box area, the configuration enhances performance by reducing the athlete's concerns about contact of the pole with the cushion and about landing.  The configuration requires correct placement of the landing cushion relative to the vaulting box in order to avoid pole contact with the cushion and thus discourages the common practice of intentional mispositioning of a cushion for such purpose.

Abstract: VARIABLE SINGLE PHASE INVERTER     ABSTRACT OF THE DISCLOSURE          A parallel inverter circuit for converting DC volt-age to a variable AC voltage.  One terminal of the DC source is connected to an inductor and, in turn, through a pair of gate-controlled, main rectifiers (SCR's), to the opposite ends of a transformer primary winding.  A center tap of the primary winding is connected to the other terminal of the DC source.  A commutating capacitance is connected across the transformer primary winding and a means is provided for alternately gating the rectifiers.  The level of the voltage wave generated across the primary winding of the transformer is varied by means of two gate-controlled, auxiliary recti-fiers (SCR's) connected in parallel across the primary wind-ing in reverse directions, and by a pair of additional wind-ings coupled to the inductor referred to above and including one such winding in series with one of the auxiliary recti-fiers and another winding in series with the other auxiliary rectifier.  The auxiliary rectifiers are gated so that one initially opens a circuit path bypassing the previously gated main rectifier as that rectifier is commutated.  After commu-tation, the other auxiliary rectifier conducts current to continue shorting across the primary winding of the trans-former to produce a zero voltage interval.  A phase-adjustable gating means is provided for the auxiliary recti-fiers.

Abstract: ABSTRACT OF THE DISCLOSURE     A flowline pull-in apparatus is operable from an overhead vessel and transports flowlines to a subsea wellhead.  The apparatus includes a sled disposed on the sea floor and connected to the flowlines.  A two-part pull-in frame, removably positioned within the sled, is connected to the overhead vessel.  The over-head vessel removes the pull-in frame and lands the frame on a wellhead.  The frame is connected to the sled by means of cables.  After the frame has been landed upon the wellhead, winches on the frame are hydraulically activated from the vessel and reel in the cables, thereby drawing the sled into engagement with the lower portion of frame and positioning flow-line mandrels, which project from the sled, adjacent the lower portion of the frame.  The cables are thereafter cut and the upper portion of the frame is released and removed by the vessel from the lower portion.  A wellhead production system is then landed on the lower portion to establish fluid communication between the flowline mandrels and the wellhead.

Abstract: MULTIPLE SPEED PRINTER     ABSTRACT      A dot matrix printer has a dot generator which projects dots through a dot selector and dot deflector towards a recording medium.  Dots used for printing are selectively charged by the dot selector and deflected vertically by the dot deflector for printing on the recording medium.  The dot generator moves horizontally at a speed S across the recording medium.  Dots not used for printing are not charged, not deflected, and are collected in a gutter.  A data input designates to the dot selector the character to be printed.  A speed selector is operable to select standard speed printing S1, or high-speed printing S2.  Speed S2 is equal to some factor Z multiplied by standard speed S1.  If the standard speed printing is selected, the dot selector accesses the standard speed character matrix memory and receives dot position information corresponding to the designated character.  The dot position information comprises X adjacent and parallel vertical scans, each scan comprising a column of Y potential dot, or matrix, positions. The dot selector codes each sequential dot with the position information for the next sequential matrix position of the scan.  If high-speed printing S2 has been selected, the dot selector accesses the high-speed character matrix memory and receives dot position information corresponding to the designated character.  The dot position information comprises X adjacent and parallel vertical scans, each scan having Y/Z     potential dot, or matrix, positions.  Since the matrix positions in the column of the scan have been reduced from Y to Y/Z, the standard scan time T is reduced to T/Z and the scan time is reduced in proportion to the increase in print speed.

Abstract: ABSTRACT "Optical device"     In an optical device an objective (1) is moved axially along its optical axis (2) relative to a frame (13) in a parallel guide (12) by means of first electro-magnetic actuating means (5) connected to the objective and second electromagnetic actuating means (7-10) arranged on the frame, which first and second actuating means co-operate axially with each other by means of a radial magnetic field which is oriented transversely of the optical axis (2) and transversely of the direction of movement of the objective. In order to suppress vibrations caused by axial reactive forces transmitted from the second actuating means (7-10) to the frame (13), axially resilient damping means (16) are interposed between the frame (13) and at least a part (8) of the second actuating means (7-10). Surprisingly, the movements, of the second actuating means (7-10) do not affect the position of the objective (1). This is because an axial displacement of the radial magnetic field relatively to the first actuating means (5) does not give rise to an axial movement of the objective (1). (figs. 1-2).

Abstract: Abstract:            "APPARATUS FOR INTRODUCING SUBSTANCES INTO LIQUIDS E.G. METAL MELTS"     For introducing gases, wires and powders to metal melts, a multi-ducted refractory body (11) is installed in the wall (14) of a vessel (15) for the melt.  The body has passage closing elements (24, 34, 35) preventing melt entering the passages (A, B, C).  Two passages (A and C) serve respectively for introducing gas, and fluidised powders, to the melt; each has a movable pipe (36, 91)  (for gas or fluidised powder).          Upon moving gas pipe (36) towards the melt, it dislodges closing element (24) whereby gas from the pipe can enter the melt via capillary bores (25).  Similarly, by moving pipe (91), closing element (35) is dislodged whereby the fluidised powder can discharge from the pipe (91).  Wire is fed along passage (B) to the melt; when it reaches the closing element (34) the wire can itself dislodge this element to gain access to the melt.      A method of introducing substances to liquids related to use of this apparatus is disclosed, as well as metallurgical processes involving the method.

Abstract: ABSTRACT A vortex flow meter includes a bluff body which sheds a vortex train when a fluid flowing in a conduit moves therepast, the vortex train developing a delicate pressure variation in proportion to a flow rate of the fluid.  The flow meter detects the flow rate by sensing the pressure variation and then converting it into an electric signal by means of a piezoelectric element or the like.  A pressure sensor is detachably mounted in a pressure sensing chamber, which is defined in an internal space of the bluff body, and comprises a pressure receiving plate displaceable in response to the pressure variation, a sensor member such as a piezoelectric element for converting the displacement into an electric signal.  The pressure receiving plate is arranged such that major part thereof is located in the conduit, while major part of the sensor member is located in a wall of the conduit and the outside thereof. The side surfaces of the pressure receiving plate are oriented parallel to or perpendicular to a direction of flow of the fluid.  A drain port is located below a pressure induction port which is formed in a bottom portion of the pressure sensing chamber, so that part of the fluid entering the pressure sensing chamber is discharged through the drain port.  The bottom wall of the pressure sensing chamber is inclined radially outwardly or formed with an upright wall.  A flange for mounting the pressure sensor on the outer wall of the conduit and a cylindrical member for accommodating the sensor member are formed independently of each other and then welded together by an electron beam or the like.  A support wall for fixing the cylindrical, member extends from the flange.  A second sensor member identical in construction with the first is employed to compensate for externally derived vibrations which may act on the pressure sensor. Leads extending out from the pressure sensor have a small rigidity.
