Patent CA-1201158-A (CA)

Abstract: ABSTRACT            A stepping motor driving circuit, in which the motor has pairs of magnetically coupled windings, includes switching transistors associated with each winding, diodes in paral-lel with the switching transistors for recycling the currents induced during current chopping, if used, and phase switching, and a diode and a capacitor, in parallel with each other and series connected between the voltage source and each pair of magnetically coupled windings. As soon as a phase winding is de-energized, the driving circuit allows recovery of the energy stored in the wind-ing by charging the capacitor coupled to it.  The energy is then returned from the capacitor to the other phase winding of the pair in case of phase switching, or depend-ing on the circuit arrangement, to the same phase winding in the case case of current chopping.  The driving circuit speeds up phase switching and therefore increases the tor-que delivered by the motor at high frequencies.

Abstract: ABSTRACT     A pair  of  thin-walled  hollow  partially  liquid-filled cushions are enclosed in cavities formed in the sole of a shoe.  The first cushion is positioned to coincide with the plantar pads on the lower sides of the wearer's metatarsals; the second to coincide with the tuberosity of the wearer's calcaneum.     BACKGROUND OF THE INVENTION                      Field of the Invention This  invention  relates  to  shoes  incorporating  shock absorbing cushions, and more particularly to shoes in which such cushions are of the partially liquid-filled type described in my United States Patent No. 4,342,157, issued 3 August 1982.     Prior Art Since my patented cushions have only recently become known to the public, the prior art offers few, if any ideas as to their use.   Experimentation has demonstrated to me that their unique construction provides a shock absorbing effect quite unlike that produced by customary prior art resilient pads, including those which contain entrapped fluids.   I believe, although I am not certain,

Title: Process and apparatus for vulcanising / pneumatic  tires /
Inventor: RUMMLER KARL-HEINZ
IPC: B29C35/02
Filed: 1984-06-07
Granted: 1987-09-29
Abstract: ABSTRACT         In order to vulcanise pneumatic tires, the tire blanks are installed in presses provided with vulcanising moulds and brought to a temperature that results in the vulcanising of the tire blank, this being done for a specific time by means of a heating medium.  To avoid the use of vulcanising times that are fixed (and, for this reason, have to be much longer than necessary) the amount of heat applied to the tire blank in each instance is determined, and the vulcanising process ended as soon as the total amount of heat required for vulcanising is reached.  To this end, at intervals the temperature on the vulcanising mould, at the heating medium lines for the hollow space of the tire blank, and the initial temperature of the tire blank are measured, and from this, on the basis of temperature curves established by test heating that are characteristic for the particular vulcanising process--for example, by process control computer--the amount of heat applied to the tire blank is measured and the heating time monitored on the basis of this.  Variously configured vulcanising moulds can be used, e. g. with or without a bladder, in particular vulcanising moulds that are divided at the centre with upper and lower halves, or vulcanising moulds made up of mould segments and mould side elements.

Abstract: ABSTRACT OF THE DISCLOSURE          Wood pulps, particularly sulphonate pulps, such as jack pine ultra-high-yield pulps produced by sulphonation, are readily discolored by metal ions commonly found in paper mills.  Additions of 0.001 to 2% on pulp dry basis of tin ions, especially derived from stannous compounds, to wood pulps effectively brighten the pulps at ambient temperature.         Metal ions such as ferrous, ferric, cupric, aluminum, nickel and manganese are common discoloring ions and pulps containing these ions can be brightened by the addition of tin ions particularly derived from stannous chloride, stannous sulphate, stannous tartrate, stannous oxolate, stannic chloride and stannic sulphate, the tin ions as Sn+2 being added in an amount to provide a ratio of stannous ions to discoloring metal ions up to about 2:1, preferably about 1.5:1.

Abstract: ABSTRACT OF THE DISCLOSURE           The specification discloses an automated chemical milling process for metal articles.  The metal article is first coated with an etchant resist coating.  In one embodiment, the area to be etched is digitized to define the x, y coordinate values for the perimeter line around the area.          A CPU is used to control a flatbed drafting table with a tangenially controlled scribing tool to cut through the resist coating along the perimeter line.  If plural etching steps are used, each perimeter line is digitized and scribed or cut in a similar manner.  All but one of the perimeter lines are recoated and marked, and the resist coating within the remaining perimeter line is removed.  The metal part is then etched as desired.  If plural etching steps are used, the resist coating for each separate area is removed between sequential etching baths.  In a second embodiment, the x, y, z point coordinate values for a perimeter line on a three-dimensional workpiece are defined, and the scribing operation is done by a robotic device controlled by a CPU.  In a third embodiment, new template or mask geometry is created on a CRT and digitized for subsequent control of the plotting table or other robotic device.  Digital signals are used to define the x, y or x, y, z point coordinate values while analog signals are used to control the scribing tool.

Abstract: Abstract:          A stage structure of an axial turbine consists of a stationary inner ring, a stationary outer wall, a row of stationary blades mounted on thy stationary inner ring and outer wall, a row of moving blades and a shroud ring mounted on the tips of the moving blades.  An annular member is disposed immediately downstream of the axial gap formed between the axial end of the shroud ring and the surface of the outer wall axially facing the axial end of the shroud ring.  The effect of this annular member is to reduce the expansion space immediately downstream of the axial gap.  As a result, circulation of the ejection flow from the main stream through the axial gap is reduced and the turbine stage efficiency there-by improved.  The annular member may be a ring fixed to the stationary outer wall, a protrusion, or a cylinder formed as part of the wall.
