Patent ES-344601-A1 (ES)
Title: Analogue-to-Digital Converter for Wide Band Signals
IPC: H03M1/00
Filed: 1967-08-30
Abstract: An analog to digital converter, of the type in which samples of an analog signal ec (Fig. 2) are sequentially fed to comparator circuits M1-Mm under the control of a sampling selector C3 and compared with a reference sawtooth waveform Z, coincidence signals being generated when the amplitudes of the analog samples are equal to the sawtooth signal, includes a binary coding counter C2, the state of which represents the instantaneous amplitude of the reference signal, the count in the counter being read into a line in a memory MR when a coincidence signal from the associated comparator occurs. In the embodiment described the coding counter controls by a decoder D the rise and fall times of the sawtooth signal Z. Each of the comparator circuits M1-Mm is enabled during one of m time intervals S1-Sm so that a capacitor in each circuit, e.g. capacitor SH (Fig. 4) in circuit Mj is charged to the value of the associated input sample. Although coincidence may occur between the sawtooth signal and the input signal whilst the capacitor is charging up, no enabling signal is then fed to the memory since it is blocked at AND gate P3 by the signal Sj. If the jth sample of the input signal ec is greater than the value of the sawtooth signal at the end of time intervals Sj, a coincidence signal occurs during one of the subsequent time intervals S and the count in counter C2 is then transferred into line j of memory MR and read out to a register RS during the time interval Sj of the next cycle of the sawtooth waveform. If the sample is less than the value of the sawtooth signal at the end of a time interval Sj no count is transferred to the memory until one of the time intervals Sm ... Sj -1 of the next cycle of sawtooth waveform Z (only Sm -1 samples being read in for each cycle). A coincidence signal from the jth comparator then occurs, the count in counter C2 being transferred to the line j of memory MR and read out during the time interval Sj of that cycle.

Title: Spring brake control valve
IPC: B60T13/26
Filed: 1969-10-03
Abstract: In a duct circuit fluid pressure braking system in which an emergency brake is spring applied and fluid pressure released, a valve 46 provides for controlled release of pressure to the brake when a leak develops in the system. Fluid pressure is supplied from reservoirs 10, 14 through conduits 18, 19 to the upper and lower halves 20, 21 of a dual pressure brake valve 22 connected respectively via pipes 24, 26 to the rear and front service brakes of a trailer, the rear brake 27 having a chamber 28 and push rod 30 and including a spring operated brake 32 with a release chamber 34. Fluid passes from pipe 24 to a chamber 97 of valve 46 by way of conduit 100 and port 98, and to chamber 34 from reservoirs 10, 14 past a pressure protection valve 16 and a check valve 12, a parking valve 90, inlet port 87 and cavity 52 a centrally located inlet port 60 and delivery cavity 48. A combined inlet and exhaust valve member 64 engages a seat 62 to disconnect cavities 48, 52 and is urged into its closed position by a spring 84 surrounding a sleeve 76 through which extends a plunger 114 having an upper piston 106 and engaging at its lower end a piston 68. In normal operation a manually or hydraulically operated handle 92 opens a valve 90 to admit fluid pressure to chamber 34 to hold the brakes released. On actuation of valve 21 the brakes are operated, fluid pressure also passing to ports 104 and 98 to equalize pressure acting oppositely on pistons 106, 68. When pressure is lost in pipe 24, valves 12, 16 close and if the valve 20 is actuated the combined downward pressure of fluid acting on pistons 106 and 68 being greater than that acting upwardly on piston 68 causes the latter to move downwardly against the action of spring 70 to close off the inlet port 60 and to cause valve member 64 to disengage seat 66 and partially exhaust pressure in line 36 via chambers 74, 78 and port 80. Spring 70 then causes valve 64 to be engaged by seat 66 again to momentarily trap pressure in chamber 34. On further application of the brakes the piston again moves downwardly and the sequence of opening and closing valve member 64 continues to give controlled application of the emergency brakes. In a further embodiment the service pressure is fed to the underside of the upper piston, and in normal operation the inlet and delivery are disconnected and the inlet and exhaust valves are lapped. In this embodiment the lower piston is made responsive to a selected pressure by means of an adjusting bolt urging the spring.

Title: Flat cable connectors having two rows of contacts
IPC: H01R12/77
Filed: 1972-01-13
Abstract: A connector for a flat cable has two opposed rows of contacts. The flat cable has signal conductors and a flat shield member which is terminated further from the end of the cable than the signal conductors. A row of signal contacts are crimped onto the signal conductors. The shield contacts extend beyond the signal contacts. The signal contacts can be crimped onto the signal conductors without making contact with the shield member. The shield contacts carry a shield connection through the connector for each signal conductor. In this way the impedance mismatch at the termination of the cable is reduced and impedance continuity through the conductor is improved.
