Abstract: ABSTRACT      A  coating  composite  provides  extended  corrosion resistance  for  substrate  metals.   The  thin  metallic undercoat of the composite contains combined metals.  The heat  curable  and  substantially  resin  free  topcoat  is established from a composition in liquid medium containing chromium in non-elemental form, which topcoat composition may further contain particulate metal.   In addition to outstanding corrosion   resistance, the composite can retain substrate weldability as well as achieving  formability, while  further enhancing  paint-ability and weatherability.

Abstract: ABSTRACT           A power transmission chain-belt, especially adapted to transmit power between the pulleys of a pulley transmission, such as a variable ratio pulley transmission. The chain-belt is constructed of a plurality of ranks or sets of interleaved links, each rank being joined to the next adjacent rank by pivot means, such as round pins, or a pin and rocker, to permit articulation of the belt. Trapezoidal load blocks carried by the chain have angled edge surfaces to drivingly contact the flanges of the pulleys. In one embodiment of the invention, a block is located between each adjacent pair of pivot means and at least one block has a different width than the other load blocks, so that its edges are free of contact with the flanges of the pulleys and thus do not drivingly engage the flanges. Substantially the same effect is achieved by "skipping" one or more load blocks in the assembly, i.e. by eliminating one or more load blocks in the chain-belt.  These arrangements change the generated noise pattern produced when the chain-belt engages the pulley flanges.  The operational noise pattern generated by a chain-belt constructed according to this invention and used in a pulley transmission results in an acoustically acceptable chain-belt for use in the automotive industry.

Abstract: AVALANCHE PHOTODETECTOR ABSTRACT OF THE DISCLOSURE The invention relates to an avalanche photo-detector having a charge-multiplication region which is spatially separated from the detector surfaces.  This photodetector includes an absorptive region, a first region overlying the absorptive region, a second region overlying the first region and having a central zone which is thinner than a peripheral zone and a third region overlying the second region.  The high electric field required for avalanche multiplication is then restricted to the portion of the first region adjacent the central zone while the field at the periphery is less than that necessary for avalanche multiplication.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a unique method for packaging a product in individual packets constructed of a sheet of flexible material.  In the method of the present invention, a sheet of flexible packaging material is formed into a generally U-shaped channel having spaced apart vertical sidewalls.  The facing surfaces of the sidewalls are sealed at vertically spaced apart locations to define a plurality of open top packets.  A predetermined amount of a flowable product is introduced into each of the open top packets.  Next, the upper corner portions of each individual packet are sealed and a predetermined portion is cut from each upper corner.  The upper corner portions of each packet then are pulled away from one another in a generally horizontal direction to urge the spaced apart upper marginal edges of the sidewalls of the packet toward one another.  After the upper corner portions have been pulled away from one another, the upper marginal edges of the packets are sealed together to close the packet.  The present invention also concerns an apparatus for packaging a product in individual packets, and a novel packet construction.

Abstract: Abstract Method and Circuitry for the Function Control of Ultrasonic Alarm Systems In an ultrasonic alarm system, in which ultrasonic waves are continuously radiated within a surveilled enclosure (R), and a frequency deviation caused by a moved object e.g. an intruder, is by virtue of the Doppler Effect determined to be cause for an alarm, the function control of the system occurs by means of modulating the emitted ultrasonic waves with many modulation frequencies present in the zone of frequency deviations determined to be cause for the giving of an alarm, so that the function test can be carried out by the same test circuit (A) as is the signal indication.  The multitude of modulation frequencies together with the turning off of the transmitter signal causes the reflected waves of varying phase condition arriving at the receiver not to combine victroially with the transmitter signal to make zero, so that a consistently reliable function control is guaranteed.  In order to identify changes in the enclosure under surveillance, the time lag of the modulation signal is compared with a reference signal (R) after the modulation signal has been turned off.

Abstract: DEPTH CONTROL VALVE AND SYSTEM FOR AGRICULTURAL IMPLEMENTS                   ABSTRACT     Disclosed is a representative agricultural implement towed by a tractor equipped by a hydraulic power source connected to a  lift mechanism for raising and lowering the implement frame so as to vary the ground-working depth of the working tools.  The frame carries a sensor responsive to changes in implement depth above and below a preselected norm.  This sensor serves as the input for the inventive control valve and system so as to control the implement lift system automatically.  The valve is designed as a four-position valve, with one of the positions serving dual modes so that the system produces fast and slow raising, fast and slow lowering and a neutral or balanced position.  The valve has a pressure port connected to the pressure side of the tractor source via a manual valve to afford three of the four active positions with one setting of the manual valve.  The fourth active position (fast raise) is achieved by changing the manual valve to reverse the pressure and return ports in the depth control valve.  Reversal of these ports acti-vates a pressure chamber and pressure-receivable area on the valve spool of the depth control valve.

Abstract: - -A B S T R A C T    "ASSAY TECHNIQUE AND EQUIPMENT"      An  article  and  a  technique  for  the  assay  of biochemical, biological or chemical species is disclosed. In essence, the article is a substrate carrying a surface relief profile  such as a regular  sinusoidal grating. There  is  usually  a  metal  layer  e.g.  of  silver  or aluminium conforming to the relief profile.  An inorganic oxide layer may coat the metal layer.  A further layer of dye-tagged material which is capable of binding the species undergoing assay is bonded to the structure.  In use,  the  grating  interacts  with  the  fluorochrome  by increasing  absorption  sensitivity  and  by  regulating fluorescent emission into a narrow cone of angles instead of there being uniform emission in all directions.  The presence of bound molecules e.g. antibodies on a layer of dye-tagged antigen affects the fluorescent behaviour of the system, which can be arranged to act as fluorescent activating  on  binding,  or  fluorescent  inhibiting  on binding of assayed species.  The fluorescent intensity or the lifetime of the fluorescent  state may be measured before and after binding in order to monitor or measure the species undergoing assay.   In the preferred case, fluoerscence is either quenched before binding of said species  and  activated  after  binding  thereof,  or  vice versa.    Also,  the  analyte  may  be  dye-tagged  (by conventional techniques) rather than the layer of binding material.  The technique is well-suited to liquid phase fluorescent immuno-assay.

Abstract: Abstract A self-contained memory gauge includes either semicon-ductor or magnetic core memory for retaining downhole infor-mation related to sampled parameters, such as borehole temperature and pressure.  A microprocessor-based computer manages the power utilization by independently and selec-tably energizing and de-energizing different sections of the gauge.  The magnetic core memory is tested for operability, and the addressing of the magnetic core memory is adjusted in accordance with any inoperable memory locations.  Samples of the monitored environmental conditions can be taken at variable rates dependent upon software monitoring of the condition, the remaining battery life and the remaining memory capacity and in response to hardware monitored pressure changes.  Each sample can be taken to a selectable resolution.  A watchdog circuit monitors the microprocessor to insure that it is operating within a preselected time limit.
