Title: Plastic carpet backing - formed by applying molten polymer with expanding agents
IPC: D06M15/693
Filed: 1971-08-13
Abstract: In a process for coating textiles with expanded products using molten polymers, a block of thermoplastic resin is melted in a blender with cylinders conveyed to a constant level tank and then forced along a jacketted tube onto the support to be coated. The polymer is pref. formed from a copolymer capable of reaction with one or more copolymerisable monomers. The reacting copolymer may be e.g. butadiene-styrene and the reactive monomer preferably ethylenically unsaturated with reactive substituents e.g. triallyl cyanurate. Applying the polymer in molten form reduces heating times and by lowering temp. allows the use of a wider range of synthetic fibres.

Abstract: ABSTRACT      In a process for controlling a particle flow system which is to be operated at slightly above the velocity at which saltation occurs, a cross correlation technique is used to determine the spread of particle velocities in the system and this is compared with a signal representing the desired spread to produce an error signal indicating the desired spread to produce an particle flow.  A second cross correlation technique, having a shorter intergration period, is used to determine the actual mean  particle velocity and this is compared with the first error signal to produce a second error signal to control the flow rate of the conveying fluid.

Abstract: UNIFORMLY COOLED PRINTED CIRCUIT BOARD MOUNTING      ASSEMBLY                      ABSTRACT OF THE DISCLOSURE           Apparatus for uniformly cooling an array of printed circuit boards mounted in a card holding means includes a high velocity centrifugal fan which is in communication with a plenum chamber secured to the lower end of the card holding means.  Dis-posed in the plenum chamber is a perforated screen configured to include a series of crests and troughs which operate as baffle means for providing resistance to the flow of high velocity air from the blower.  The screen causes turbulence which reduces the velocity and uniformly directs the airflow through openings in the plenum chamber to the spaces between the array of printed circuit boards.  The airflow thus divided cools each card on both sides as the air flows from bottom to top, thereby displac-ing the warmer air heated by the components mounted on the printed circuit boards.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus is disclosed by which high voltage and current can be produced by a polycrystalline ferroelectric ceramic material in response to incident light.  Numerous applications of the ferroelectric ceramic material taking advantage of such properties thereof are further disclosed.   The  polycrystalline ferroelectric cera-mic material is initially poled by the application thereto of a pulse of voltage of predetermined magnitude and direction.    After being poled in such fashion, the appli-cation of light impinging on the various surfaces of the ferroelectric ceramic material will induce a consistent high voltage between select surface of the ferroelectric ceramic material.  Upon disposing electrodes in conductive contact with the material, a current can be generated to a load attached there-across. Importantly, the magnitude of the voltage produced upon the application of incident light is directly proportional to the remanent polarization of the ferroelectric ceramic material, and is further directly proportional to the length of the material, the polarity of the high voltage being dependent upon the polarity of the remanent polarization and being capable of being reversed when the remanent polarization is reversed. The open circuit voltages produced by the ferroelectric ceramic material are orders of magnitude higher than those which typically have been produced in the prior-art through the utilization of standard photovoltaic materials.

Abstract: ABSTRACT         In a current controlled source of high-voltage current fed from a low-voltage current source and supplying a high-voltage direct current to two output terminals, an error voltage result-ing from the comparison of a constant reference voltage with the voltage appearing at the terminals of a resistor supplied with a current proportional to the current to be controlled acts on the amplitude of an alternating current signal produced by an oscillator.  The variations in the amplitude of the signal produced by the oscillator in turn cause the high voltage current supplied to said output terminals to vary.

Title: Door operator with instant reverse feature
Inventor: GATLAND GEOFFREY H

Granted: 1978-11-21
Abstract: ABSTRACT OF THE DISCLOSURE         An improved garage door operator of the motor-driven chain-and-sprocket type comprising a molded plastic gear case assembly supporting an output shaft for rotation relative thereto.  A molded plastic worm wheel is loosely disposed on the shaft for limited rotation relative thereto and is driven by a reversible electric motor through a worm.          Camming surfaces on the worm wheel and a second element which is fixedly disposed on the shaft form a low-torque coupling such that under normal conditions the motor drives the shaft to move the garage door.  If the door encounters an obstacle and is unable to move, continued rotation of the motor drives the cam surface of the second element up the cam surface of the wheel so as to axially shift the second element relative to the gear case to trip a reversing switch.  Up and down limits are established by means of a small threaded shaft which is driven off of the worm wheel and which produces linear displacement of a limit switch actuator traveler.  The traveler carries adjustable dogs which operate respective limit switches in a limit switch carrier which is mounted on the gear case.

Abstract: ABSTRACT OF THE DISCLOSURE      An exhaust manifold for a multi-cylinder engine employs three concentric exhaust reaction chambers.  Exhaust inlet pipes convey hot exhaust gases from the exhaust ports of the engine directly into the innermost reaction chamber.  The concentric reaction chambers extend substantially at right angles to the exhaust inlet pipes which are parallel.  Concentric tubes encircle the exhaust inlet pipes and each is connected to one of the concent-ric exhaust chambers.  The flared portions of the exhaust inlet pipes engage in surface contact with the correspondingly flared portions of the tubes.  End members having concentric shoulders engage cylindrical shells which defines the exhaust reaction chambers.  Bolted spacers are positioned substantially midway of the length of the shells and space them in concentric fashion.

Abstract: REGENERATIVE D.C. MOTOR CONTROL HAVING FIELD AND ARMATURE CONTROL                    Abstract of the Disclosure A regenerative motor control of the field reversing type includes an input amplifier coupled to a field circuit for energizing the motor field and an armature circuit for energizing the motor armature.  A limit circuit connected to the input amplifier and field winding is responsive to the magnitude and direction of field current.  The limit circuit retains the output of the input amplifier at a level insuffi-cient to establish armature current until the field current is established.  Thereafter, the output of the amplifier, and the armature current, may increase within the limit established by the existing field current.  The d.c. motor control prevents application of undesirably large armature currents to the motor while providing fast response characteristics.

Abstract: INDEPENDENT REDUNDANT CLUTCHLESS            RETRACTOR         Abstract of the Disclosure A safety belt retractor having a pair of actuating means which are independently responsive or condition sensitive to acceleration of webbing withdrawal and to omnidirectional acceleration or deceleration of the vehicle. The condition sensed first actuates a pilot pawl and the pilot pawl mechanically and positively engages means which drive the locking pawl to prevent webbing withdrawal from the webbing drum or reel. The pilot pawl is cam activated by the relative movement between a flywheel and the shaft of the drum or reel as is sensed by sudden withdrawal force on the webbing, or upon relative delay of rotation or lag in the flywheel consequent to inertial displacement of a pendulum and following pawl to ratchet engage-ment with the flywheel. The locking force of pilot pawl to drive the ratchet and the locking force to drive the pendulum pawl to the flywheel ratchet is minimal and the locking thrust of the lock pawl to the ratchet drum is by emergency stress felt on the harness or webbing and conveyed into the retractor frame and vehicle. The pendulum is miniaturized and the actuator mechanism is predominantly formed from precision molded resin parts.

Abstract: ABSTRACT OF THE DISCLOSURE             A process for producing petroleum from subter-ranean formations is disclosed wherein production from the formation is obtained by driving a fluid from an in-jection well to a production well.  The process involves injecting into the formation via the injection well an aqueous solution of ethoxylated asphalts as a sacrificial agent to inhibit the deposition of surfactant and/or poly-mer on the reservoir matrix.  Normally the process would be carried out by first injecting the ethoxylated asphalts into the formation through the injection well and following them with either a polymer or a surfactant solution.  The polymer and/or surfactant would then be followed by a drive fluid such as water to push the chemicals to the production well.

Abstract: ABSTRACT:           Halogen incandescent lamps having at least two filaments are provided with a hard-glass lamp vessel in the vacuum-tight seal of which molybdenum wire current leadthrough conductors are incorporated which form one assembly with internal and external current conductors. The part of the current leadthrough conductors which extends in the seal of the lamp vessel is according to the invention surrounded by a glass bead.  In spite of large differences between the coefficients of expansion of the glass and the molybdenum, the lacking of rotation-ally symmetric geometry at the area of the current lead-throughs and the high thermal load of the lamp vessel seal, the lamps have proved to be very reliable.
