Title: A circuit for generating line frequency and PAL sub-carrier freqtiency signals
IPC: H04N9/45
Filed: 1980-02-15
Abstract: A voltage controlled oscillator VCO 1 operates at a multiple of   <IMAGE> where fl is the line frequency and n depends on the line standard, and a crystal controlled subcarrier frequency oscillator 3 provides a signal at the sub-carrier frequency   <IMAGE> where 1 DIVIDED 4fl+fv are the quarter line offset and frame offset terms. A divider 2 provides a signal 2fl. A signal   <IMAGE> divider from the output of the VCO 1, is mixed 14 with the output of the osciliator 3 and filtered 15 to provide a signal (1 DIVIDED 4fl+fv), a similar signal being provided by a chain of dividers (5, 6, 9, 12) and multipliers (7 and 8, 10 and 11) connected to the VCO 1. Phase comparison 16 of the two signals controls VCO 1. Each multiplier consists of a phase locked loop. The circuit does not require complex tuned filters.

Title: Finishing Method and Apparatus for Conventional Hot Dip Coating of a Ferrous Base Metal Strip With a Molten Coating Metal
IPC: C23C2/20
Filed: 1980-04-02
Abstract: A finishing method and apparatus for conventional continuous hot-dip coating of the type wherein a ferrous base metal strip is caused to pass beneath the surface of a coating bath of molten coating metal and is thereafter subjected to jet finishing, the ferrous base metal strip having been appropriately pretreated so as to be at the proper coating temperature and so as to have its surfaces oxide- free when passing through the bath of molten coating metal. The method (see Figure 2) comprises the steps of providing an enclosure for the two-side coated strip (9) as it exits the coating bath (7), locating a finishing jet nozzle (28, 29) to either side of the coated strip within the enclosure, jet finishing the coated strip with a non-oxidizing or inert gas and maintaining the jet finishing gas and the atmosphere within the enclosure at an oxygen level of less than about 200 parts per million. The apparatus comprises the above mentioned enclosure with the jet finishing nozzles located therein and an appropriate system (34) which provides a non-oxidizing or inert atmosphere within the enclosure.

Title: Method and Apparatus for Making Printed Circuit Boards
IPC: H05K3/00
Filed: 1982-01-15
Abstract: Printed circuit boards are made by imaging a liquid polymer which has been coated onto the board. The imaging is accomplished while the polymer is wet with the photo tool in a close air gap relationship with the coated board. The uncured polymer which remains liquid is removed after imaging so that the board can be processed by etch resist, plate resist, or solder mask techniques. The cured polymer is removed by stripping with an alkaline solution. The apparatus consists of single station or multi- station equipment to carry out the unit operations of maintaining the board in a set position, coating with a liquid polymer, placing a photo tool in registration with the circuit board blank and in close relationship with the coating, and imaging the liquid polymer via the photo tool to cause areas of the coating to solidify and other areas to remain liquid.

Title: Improvements relating to sewage disposal systems
Inventor: MCBRIDE GEOFFREY JOHN HAMILTON
IPC: C02F3/12
Filed: 1982-10-12
Abstract: A sewage disposal system has the sewage rendered harmless by bacterial action and discharges purified water. The sewage is deposited in a mesh trap (7) immersed in water and filtered liquid escapes to mix with that water and follows a labyrinthine path (11,10,17) to a recirculation pump (15). The water is pumped back to the underside of the trap and on its return it is aerated to help sustain the bacterial action as it is diffused up through the trap. The aerated water is also diffused through the filtered water at the upstream end (10) of the labyrinthine path. Towards the downstream end (17) the water and suspended particles are settled out and directed to the pump inlet, while any excess is discharged at the extreme downstream end (20). <IMAGE>
