Patent CA-1129029-A (CA)

Abstract: Abstract of the Disclosure In digital transmission systems where a signal is converted into parallel bits which differ in significance from each other and which are then transmitted via respective transmission routes, failure of any one transmission route gives rise to noise.  However, the level of the noise depends on whether the faulty transmission route is being used to carry a highly significant bit (in which case the noise level is high) or a less significant bit.  If the route carrying a highly significant bit fails it is usually necessary to interrupt the transmission signal to remedy the trouble but if a bit of low significance is interrupted the noise level resulting is not sufficient to make the overall signal transmitted unacceptable.  The invention makes use of this fact by providing switches in the transmission routes which enable the transmission routes to be interchanged so that if the transmission route which is nominally assigned to a highly significant bit is interrupted, the least significant bit is switched in to the faulty transmission route and, the highly-significant bit is moved into an adjacent transmission route.  The other bits are moved respectively to adjacent transmission routes to accommodate the highly significant bit.

Abstract: ABSTRACT OF THE DISCLOSURE         A poppet valve member for use in pneumatic apparatus for driving fasteners or for other impacting applications.  The valve member is useful for rapidly admitting high pressure air on command to the upper end of the drive cylinder of the apparatus.  The valve member has a hollow circular body with different diameters at the ends, one end being closed off by an end wall.  A coaxial extension formed on the end wall extends away from the body while a boss, formed on the other side of the end wall, extends coaxially within the body.  A plate attached to the boss closes the other end of the body and has a smaller diameter than the outer diameter of the one end.          Finally, a passageway extends through the extension, the end wall, the boss and the plate for conducting air through the valve member.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved dishwashing system includes operating methods and apparatus for water and energy conservation and elimination of spot-reducing chemicals in the rinse water. return water from the rinse cycle is stored in insulated tanks and rinse water flowing to the dishwasher absorbs heat from the return water to thereby conserve the heat energy of the return water while simultaneously cooling the return water to a selected temperature in preparing a feed solution for mem-brane separation.  A controlled quantity of make-up water is added to the feed solution which is raised to a selected pressure to provide for reverse osmosis purification and de-ionization.  The reverse osmosis effluent is accumulated and, when needed, boosted in pressure to a desired operational dishwasher pressure, and heated to sanitizing level so as to achieve desired bacterial count levels during rinse cycles.  Rinsing with the purified and deionized water results in film-free and spot-free dishes after drying.

Abstract: SWITCHED CAPACITOR ELLIPTIC FILTER             Abstract of the Disclosure A switched capacitor sampled data elliptic filter for data transmission or communication systems is disclosed.  The filter section comprises three integrating operational amplifiers connected in series with a negative feedback connection between the output of the second operational amplifier and the input to the first operational amplifier, which is also connected to the input voltage source.  Signals via a feed forward connection from the input voltage source and the outputs of the first and second operational amplifiers are summed by the third operational amplifi-er.  Switched capacitors in the feed forward connection, the negative feedback connection, the inputs to all three operational amplifiers and in feedback sections of the first and third operational amplifiers are all connected to a two-phase clock driver operated at a preselected frequency.  The circuit arrange-ment realizes finite transmission zeros in the transfer  unction which produce a sharp transition from pass band to stop band with a lower order, and the values of all capacitors may be calculated to provide the filter with a loss response within preselected limits.

Abstract: ABSTRACT OF THE DISCLOSURE         In a drilling and chipping hammer, an internal combustion engine drives a crankshaft which, in turn, drives a percussion piston.  The hammer includes a housing divided into two separate spaces, one communicating with the percussion mechanism and the other communicating with the internal combustion engine.  Air or a fuel-air mixture is supplied through a valve in the housing into the percussion mechanism space.  As the percussion piston is driven during one part of its reciprocating movement it draws the air or fuel-air mixture into the percussion mechanism space.          During the other part of its reciprocating movement, the percussion piston forces the air or fuel-air mixture from the space through a flow passageway into the combustion space in the engine.
