Title: N.T.S.C. colour television signal processing
IPC: H04N9/64
Filed: 1980-04-15
Abstract: In apparatus for processing 525-line N.T.S.C. colour television signals, in which in conjunction with each line of the signal there is provided an additional signal for use therewith, the additional signal is formed essentially of the luminance component of a signal equivalent to the signal M 525 lines previous to the current line, and the chrominance component of a signal substantially equivalent to the signal T 524 or B 526 line previous to the current line, or an average of these, the form of the chrominance component being selected automatically by a circuit 80 in dependence upon correlation of vertical chrominance detail in lines B, M and T. The circuit 80, which may also be applicable to PAL signals, provides moduli DB and DT of the differences between the chrominance components of lines B, M, and M, T, respectively and produces therefrom a signal   <IMAGE> determining whether, and in what sense, a signal 1 DIVIDED 2(T - B) from subtractor 64 is combined with a signal 1 DIVIDED 2(T + B - 2M) from adder 62. The resulting signal is filtered for the chrominance component and added to the full line M at 72. <IMAGE>

Title: Impact ripper
IPC: E02F5/30
Filed: 1979-02-12
Abstract: An improved ripper assembly (10) wherein a ripper shank (19) is mounted to the beam (11) of a tractor by a clevis pin (22) so as to minimize side forces acting on the shank pin (25). The vertical axis of the clevis pin may be aligned with the distal end (34) of the ripper tip (21) and the horizontal axis (24) of the shank pivot pin (25). The impact surfaces (28, 29) of the impacting mechanism (18) and shank (19) preferably define a plane of abutment in which lies a radius (30) from the horizontal shank pivot pin axis (24). This plane is further preferably accurately perpendicular to the ripper tip axis (31) extending perpendicularly to the radius (30). The arrangement provides a free pivoting action of the ripper assembly about the vertical axis of the clevis pin so as to effectively minimize side loads for improved extended life of the ripper assembly (10).

Title: Trans-synchronous motor apparatus and method
Filed: 1981-01-28
Abstract: This disclosure is concerned with a motor technique for generating speeds that are fractions of synchronous speeds, through novel time-staggered selected full half-cycle energization of a plurality of magnetic poles by a controlled switching sequence, generating such a fractional motor speed that would otherwise have to be produced by a much larger number of magnetic poles. <IMAGE>
Patent GB-2068621-A (GB)
Title: Testing coins
IPC: G07D5/08
Filed: 1981-02-05
Abstract: A coin testing apparatus comprises transmitting and receiving coils (14) and (15) on opposite sides of a coin passageway (11). The transmitting coil is connected to high and low frequency oscillators (16) and (17). The output of the receiving coil is separated into the high and low frequency components by a high pass filter (21) and a band pass filter (22). In the high frequency channel the signal is amplitude controlled by a voltage controlled amplifier (23) rectified by a rectifier (24) and smoothed by a long time-constant circuit (26). The initial rise in level caused by a coin entering between the coils (14) and (15) is detected by an instantaneous level change comparator (32) which responds to the rate of change of signal level at the output of the long time- constant circuit (26) becoming equal to a preset threshold and causes a normally closed switch (27) to be opened. When the switch (27) is closed a comparator (31) compares the signal with a reference value from a source (30) and adjusts the gain of the amplifier (23) until the signal corresponds to the reference value. Upon the arrival of the coin the switch (27) is opened and a long time-constant circuit (28) causes the gain of the amplifier (23) to be maintained at the level before the arrival of the coin. A window comparator (33) compares the difference in voltage with voltage ranges for acceptable coins. A similar arrangement is provided in the low frequency channel. <IMAGE>

Title: Telecommunications terminal
Inventor: ASHWORTH DAVID
IPC: H04M11/06
Filed: 1981-11-19
Abstract: A telecommunications terminal includes a viewdata decoder (1), which can, in response to requests via a keyboard (8), request information from a remote centre. The terminal's usefulness is extended to enable it to act as an "electronic mail" terminal. For this it has a ringing detector (13) which responds to an incoming call and, after a period to permit human intervention, connects the line to the decoder (1). When the latter is satisfied that it is the correct destination for a call it sends a "proceed" signal to the remote terminal as a result of which the message is sent therefrom. On reception it is placed in temporary storage (3), possibly with error detection and correction, whereafter it is printed out (10) or put on tape (11), and the call released. <IMAGE>

Title: Fluid viscosity control for actuator circuit
IPC: F15B21/045
Filed: 1980-09-29
