Abstract: ABSTRACT                  ROLL COMPACTING OF POLYMER            POWDERS INTO FULLY DENSE PRODUCTS          A flowable thermoplastic polymer powder is fed to the nip of a pair of cooperatively rotating com-pression rolls whereupon the polymer feed is passed between the rolls which compact and cause the particles to coalesce into a shaped article which thereupon emerges from between the rolls in the form of a sheet or film.          During the operation, the circumferential speed of the rolls is maintained essentially equal to the linear speed of the sheet or film exiting therefrom. The sheet or film is withdrawn from between the rolls under tension at a force which is adjusted so as not to exceed the elastic limit of the resulting sheet or film product.  Flowable thermosetting polymer powder is also compacted into fully dense products by feeding the powder to the nip of a pair of cooperatively rotating compression rolls, whereupon  he polymer feed is passed between rolls which compact and cause the particles to cold weld.

Abstract: BOAT                             Abstract A boat which greatly reduces ventilation under a boat and cavitation in an outboard motor's propeller is disclosed. Preferably, a skeg and hulls are arranged to produce a zone be-hind the boat which is substantially free of froth and in which a propeller may operate efficiently.  Preferably, the skeg is trapezoidal in cross-section with substantially planar surfaces. It runs forward from its broad end to its source, which prefer-ably lies in a section about 60-75% of the boat's length forward from the stern.  Channels running between the skeg and hulls uniformly decrease in area as they run aftward.  Thus, lift of the stern is increased by the increase in the apparent water pressure and velocity in the channels.  The skeg's shape acts as a shield for the propeller and helps to direct the water out-wardly to develop a zone behind the skeg where the motor can operate more efficiently.

Title: Preparing substrate surface for electroless plating
Inventor: MALLORY GLENN O JR
IPC: B05C11/00
Filed: 1982-06-25
Granted: 1984-06-19
Abstract: Abstract of the Disclosure Polyalloy catalytic coating formulations are included in a multiple bath system or composite bath in order to prepare a metallic substrate surface to enhance subsequent plating thereover of nickel, cobalt or polyalloys including nickel or cobalt.  Within this bath system, these catalytic formulations are rinsed Subsequent to their application onto the substrate and prior to the electoless deposition thereover.  Improved products such as printed wiring boards are provided that are resistant to the development of bridging within the circuitry pattern and to undesirable increases in the conductivity of the board at locations other than on the circuitry pattern to produce printed wiring boards that are extremely resistent to developing short circuiting problems.  Such properties are achieved, in large measure, because copper specks that are left embedded on the non-conductive board do not have any substantial electroless plating thereon.

Abstract: ABSTRACT OF THE DISCLOSURE         A safety circuit which connects a condition responsive circuit to a cyclic signal detecting circuit.  In order to provide the cyclic signal detecting circuit with a continuous cyclic input, the condition responsive circuit and a cyclic redundancy checker is provided.  The cyclic redundancy checker identifies a specific series of logic bits from the condition responsive circuit and responds favourably only to that series of logic bits.  If any other series of logic bits occurs, the cyclic redundancy checker of the system ceases to function, thereby causing the cyclic signal detecting circuit to cease to function and it in turn opens a series contact to deenergize a critical load in a control system.

Abstract: Abstract of the Disclosure A furnace stack damper control apparatus has a motor for connection to a stack damper to open the damper upon a call for heat by a space thermostat. The motor is driven in a closed direction by electrical energization and in an open direction by a spring return. A relay having two normally open switches and a normally closed switch is energized when a space thermostat calls for heat.  The normally closed switch then opens to allow the damper motor to open the damper by the spring return.  The motor has an end switch having a normally open and a normally closed circuit. The normally open circuit is used with one of the normally open switches of the relay to energize a gas valve when the damper is open.  The normally closed end switch is used to provide the energization circuit for the relay by the space thermostat and the relay is maintained energized when the damper is open by the other normally open switch of the relay connected in parallel to the normally closed end switch.  The circuit provides for additional safety in that normal operation of the gas valve control apparatus does not take place if the normally open or normally closed end switches stick in either position.
