Abstract: ABSTRACT OF THE DISCLOSURE      A method of controlling the flow rate of viscous fluid for feeding the fluid under pressure by an ON/OFF type spray gun with a constant-capacity type pump which comprises the steps of detecting the temperature and the pressure of the viscous fluid in a hose for coupling the pump with the gun when the fluid is not exhausted from the gun in an OFF mode, calculating viscous fluid supplying pressure to obtain a target set flow rate from preset temperature-supplying pressure characteristic data at the detected temperature, comparing the detected pressure of the fluid with the calculated supplying pressure to control the exhausting pressure of the pump so that the detected pressure coincides with the supplying pressure, and operating the pump at a constant speed to provide the target set flow rate.  An apparatus for controlling the flow rate of viscous fluid for executing the above method is also provided.  Thus, the method can always feed the viscous fluid at a constant flow rate even if the viscosity of the fluid varies due  to temperature change and feed the fluid at a stable constant flow rate from immediately after the start of exhausting the fluid from a spray gun.

Title: Quick change fountain
Inventor: DIFRANK FRANK J
IPC: B05C1/02
Filed: 1987-07-16
Granted: 1991-10-15
Abstract: ABSTRACT OF DISCLOSURE In the application of a solvent to a plastic label carried on the surface of a vacuum drum, the solvent for the plastic label is transferred from a gravure roll to the label at finite areas on the label so that the label can adhere to the bottle to be labeled and to itself to form a complete sleeve label.  The gravure roll is supplied from a fountain that is held against the roll under a spring force.  The fountain is in the form of a plastic block which has a face that has several undercut channels in one of which the solvent is supplied and with the others acting as doctor channels to carry away any excess solvent from the roll surface.    The fountain block is held by a vertical support plate that, in turn, is held to the surface of a vertical mounting plate by a quick release toggle clamp.  The support plate and the spring biased fountain are released by the toggle clamp so the fountain can be removed without requiring any tools for easy inspecting and clearing of any labels that may become adhered to the gravure roll with a minimum of time involved.  If it is necessary to change the fountain, only a pair of supply and return hoses to the fountain need be changed and the new fountain easily and quickly replaced.  The toggle clamp and the mounting system serve as the quick disconnect fountain mounting arrangement.

Title: Control of rf pulses in a tv answer back system
Inventor: MORALES-GARZA FERNANDO
IPC: H04N9/00

Granted: 1993-09-28
Abstract: CONTROL OF RF PULSES IN A TV ANSWER BACK SYSTEM            ABSTRACT OF THE DISCLOSURE:  In a TV answer back system where many receiver stations communicate with a TV transmitter station by means of rf pulses generated by rf oscillators at the receiver station, the requirement for keeping all oscillators on frequency is achieved without crystal control by automatically controlling the rf oscillator frequency using synchronization signals carried in the video signal received from the TV studio. By this invention it has been possible to control the frequency of multiple megahertz oscillator as accurately as desired from relatively low frequency synchronizing signals Such as the vertical and horizontal video sync pulses. Thus an oscillations counter is gated for a very accurate time period by the sync pulses, and the oscillation count is compared with a datum count representing the desired oscillation frequency. The requirement to prevent receiver stations from answering with rf pulses in response to querles contained in home video recordings of previously broadcast signals is achieved by encoding broadcast time on all query containing TV transmissions, and by comparing at receiver stations broadcast time Information from received signal with time from a local battery backed clock contained at each receiver station, thus discrimination of video recordings is possible by comparing received video broadcast time with local time.

Abstract: ABSTRACT                  AN OPTICAL SWITCH   An optical switch which selectively transmits or does not transmit light from an input optical fibre (10) to an output optical waveguide (11, 12) has one of the input (10) and output (11, 12) optical waveguides an optical fibre which is flexible and mounted to be capable of movement towards and away from the other, and an electrode (14) arranged to subject the one optical waveguide to an electrostatic field.  In use, application of an electrical potential to the electrode (14) causes the one optical waveguide to move in a direction to enable or prevent optical coupling between the waveguides and hence operation of the switch.  The optical fibre is a D-fibre so that it is more flexible in that direction is providing the fibre with a degree of self-alignment.  It is preferred that the one optical waveguide is entirely electrically non-conducting and that the optical switch includes more than one electrode (14) to provide a non-uniform electrostatic field.  In this case the one optical waveguide is caused to move towards the region of highest electrostatic field density and so move towards or away from the other waveguide to enable or prevent optical coupling between them.
