Title: Forming halftone images
Inventor: WALLER ROBERT W
IPC: H04N1/405
Filed: 1982-12-22
Abstract: A photocomposing system includes an image read subassembly (Fig. 1 not shown) which scans an original image and records a digital representation thereof in memory 68. For each cell of the image the tonal density of a plurality of points is determined and the read subassembly determines whether each cell is high or low detail. For low detail cells an average tonal density value is recorded and for high detail all the tonal density values are recorded. An image record subassembly selects a single dot character from memory 110 for low detail cells and displays it in the corresponding cell on c.r.t. 114. For high detail cells the individual density values are read from memory 68 to register 164. Logic 166 includes timing control 200 and gates 202-208 which supply the values successively to the character display circuitry 106-118. Quadrant positioner 212 positions the selected character at the appropriate position within the cell. Logic 170 may also select the size and shape of a single dot character and determine its position within the cell. <IMAGE>

Title: Pipe couplings
Inventor: LARGE JACK ADRIAN
IPC: F16L21/06
Filed: 1983-01-28
Abstract: A pipe coupling has a body (1) with a sleeve at one end to receive plastic pipe (P). The sleeve has annular saw-tooth profile serrations and a groove housing an O-ring. A radial compression clamp (3) is used to force pipe (P) onto the serrations and in this action considerable movement takes place in the tightening and arrangements are provided to ensure that there is no side-strain or binding on the bolt (6). This is achieved in the following manner; The clamp lugs (7) are laterally machined in the form of a segment of a circle (8). Located in these segments are half round blocks (9) centrally drilled to accept the bolt (6) and free to axially rock in the circular segment (8). The clamp lugs (7) are bored with a clearance hole (10) sufficiently large to provide clearance on the bolt when the lugs have undergone maximum movement due to closing. In the fully tightened position the bolts are correctly longitudinally loaded, and no side-strains or binding arises due to the closing action of the clamp. The bolts are tightened by action on the nuts (11), located one at each end of the bolt.

Title: Automatic bias control system for an image reproducing device
Inventor: PARKER ROBERT PRESTON
IPC: H04N9/72
Filed: 1983-10-13
Abstract: An automatic kinescope bias (AKB) control system includes a sampling amplifier (52) which provides an output current for charging and discharging a storage capacitor (56) in response to the amplitude of a derived pulse V1) representative of the black current level conducted by the kinescope of a television receiver. The derived pulse amplitude is greater than zero when the black current level is correct, and is applied to the amplifier via an input signal coupling path. During sampling intervals, an auxiliary pulse (Vp) is applied to the input signal path with a magnitude and sense for negating the amplitude of the derived pulse at the amplifier input when the derived pulse amplitude corresponds to the correct black current level. Accordingly, the amplifier conduction and the voltage on the storage capacitor remain unchanged. An impedance included in the signal path compensates for impedance variations at a sense point from which the black current representative signal is derived. <IMAGE>

Title: Gasifying beverage during dispensing
Inventor: HEDDERICK JOHN BARCLAY
IPC: B67D1/12
Filed: 1985-03-11
Abstract: A beverage dispensing system and distributing process with such a system has a flexible bag 1 containing the beverage which may have carbon dioxide dissolved therein. The beverage is drawn off through a pipe 3 (assisted by a pump 8) for dispensing through nozzle 5 having a tap 6.

Title: Fluid conductivity sensing circuit
Inventor: MILLER FRANCIS M
IPC: G01N27/06
Filed: 1986-06-16
Abstract: The circuit can be used to detonate an electro explosive device 86 for operating a release mechanism for uncoupling a parachute canopy from its load upon landing in water. An SCR 60 is turned on to charge an ignition capacitor 64 when a conductivity sensing circuit 70,72,74,78 senses the conductivity between electrodes 24,34 and the rate of change of conductivity to be above certain levels. A voltage independent portion of an operating network turns on an SCR 90 after a time delay from the start of charging of capacitor 64, which delay is independent of the rate of voltage rise on capacitor 64. The SCR 90 discharges the capacitor 64 through the device 86 to activate it. The operating network also has a voltage dependent portion which, when a voltage of predetermined magnitude is developed on the conductivity sensing circuit in response to fluid not having the predetermined condition of conductivity, turns on SCR 90 to define the discharge path through the device 86 when the energy level in capacitor 64 is insufficient to detonate the electro explosive device. A regulated current source 78 is connected in relation to the conductivity sensing circuit and to the electrodes 24,34 thereof in a manner placing the battery voltage 46 across the electrodes when the conductivity is below a predetermined magnitude so that the sensing circuit does not respond thereto and placing the battery voltage across the sensing circuit when the conductivity is greater than a predetermined magnitude. The electrodes 24,34 are of dissimilar metals so selected and connected relative to the polarity portions of the circuit to maximize utilization of the battery output voltage. <IMAGE>
