Title: Method of, and apparatus for, scrambling a tv picture
IPC: H04N7/171
Filed: 1984-07-06
Abstract: A television signal transmission system of this invention 
transmits a television signal having a polarity inverted 
portion in association with a scene change portion and a 
polarity inverted portion for a predetermined time interval 
independently of the scene change portion. The scrambled 
signal is generated by detecting a change in the scene 
represented by the television signal and generating a scene 
change identification signal in response thereto;  
generating a key code signal having a predetermined 
pattern;  
combining said scene change identification signal and 
said key code signal to produce said first control signal;  
producing said second control signal; and  
scrambling the television signal in response to said first 
control signal or said second control signal.

Title: Method to improve the endurance and reliability of patch-rubbers and of tires repaired or retreaded by means of the same patch-rubbers
IPC: B29C73/10
Filed: 1987-09-28
Abstract: The method according to the invention allows the production of patch-rubbers intended to repair radial-ply and bias-ply tires. Said patch-rubbers, while showing the same strength as the nowadays known, are more flexible and do not affect the original mechanical features and performances of the regions of the tires having been repaired therewith. The patch-rubbers obtained by implementing the method are also suitable to perform retreading operations on tires by means of both high pressure molding machines and autoclaves. The method essentially consists in inclining, in respect of the longitudinal or symmetry axes of the patch-rubbers, alternatively in the clockwise and in the counterclockwise direction, the cords made of a fibre and embedded into each one ply of a plurality of superposed plies, and in superposing to said plies, having said cords made of a fibre embedded therein, a further ply of smaller area having rectilinear metallic or fibre cords embedded therein; said further ply being so positioned that, when the patch-rubber is applied to the tire to be repaired, said metallic or fibre cords either match the direction of the radial metallic cords forming the casing of radial-ply tires in the sidewalls and in the tread respectively, or form a given angle with the direction of the biased metallic cords forming the casing of bias-ply tires.

IPC: H03H19/00
Filed: 1987-04-23
Abstract: A continuous time electrical filter fabricated as an in­
tegrated circuit includes capacitors (CF,CN) and resistors 
(R1,R2). Since capacitors and resistors are difficult to in­
tegrate with accurately defined values a trimming circuit is 
provided which operates switches (S1-SN) to select ap­
propriate ones of the capacitors (CN) to accurately define the 
cut-off frequency of the filter.  
     The trimming circuit comprises a capacitor (TC2) which is 
charged through a resistor TR1 during a first period and 
which is discharged in incremental steps by capacitor (TC1). 
The number of incremental steps is counted by a counter (11) 
and transferred to a register (13). The outputs (S1-SN) of the 
register (13) control the switches (S1-SN). Instead of adjust­
ing the value of the capacitors in the filter the values of the 
resistors may be adjusted. If this is done a convenient proce­
dure is to short out selected portions of the resistors. More 
than one capacitor or resistor may be adjusted using a single 
counter and register.  
     The trimming circuit also includes a switch (TS11) which 
connects the parasitic capacitance (CP1, CP2) of the capacitor 
(TC1) and an underlying conductive layer (22) and of a 
dummy resistor and the underlying layer (22) in parallel with 
the capacitor (TC1). The filter circuit is arranged so that the 
parasitic capacitance between the resistor (R1) and an under­
lying conductive layer and that between the capacitors (CF, 
CN) and the underlying conductive layer are connected in 
parallel with the fixed capacitor CF.
