Abstract: In a sliding clasp fastener having an open end fitting comprising a pin member 6, Figs. 3, 4 carried on a stringer tape 2a and a socket member 5 carried on a second stringer tape 2, the stringer tapes being of woven material, a reinforcement 9 of thickness not greater than that of the tape is substituted for the woven material in an area adjacent the pin member 6, the area comprising that portion of the stringer tape which enters the tape gap of a slider when the pin member is inserted in the socket member 5. As shown, the reinforcement 9 is in the form of a web integrally connected with pin 6 and with a rib 10, the latter being formed with a spigot portion 13 for locating the rib as it passes through the slider channel. Both pin and socket members are formed of a plastics material by injection moulding operations, and the pin member web and rib formation is located in a cut away 8, Fig. 1, of a gap-space between adjacent series of fastener elements 1a. Plastics material is also moulded across the tape at a position 14 where the tape is subsequently cut to produce a fastener stringer. The arrangement is such that when the stringer ends are united by the members 5 and 6, the pin member 6 is located outside the slider when the latter is positioned at that end of the stringers. In another embodiment, Fig. 9 (not shown) a pin member is moulded on the inner edge of the tape and the cut away is in the form of an aperture. A web of plastics material is moulded in the aperture and connects with a reinforcement which is provided with slots for the passage of a needle when the fastener is sewn to a garment.

Patent ES-346586-A1 (ES)
Title: Decoder
IPC: H03M1/00
Filed: 1967-10-30
Abstract: In a PCM system the signals are decoded by being applied to a counter 1 to enter a value representing the sample and to a waveform generator 2 triggered by the incoming signal to produce a damped oscillation which is fed to a threshold detector 3 the output pulses of which are applied to the counter to count up from the value entered until the counter is full, when a signal is produced to sample the amplitude of the waveform and apply it to a peak storage circuit. In the encoder the amplitude sample is applied to shock-excite a damped oscillator, and the number of oscillations exceeding a predetermined threshold are counted. The number obtained is a representation of the amplitude of the input signal compressed according to a law depending on the rate of damping of the oscillator. In the decoder the damping rate of the oscillator is the same so that the output is a linear representation of the original input. The incoming PCM signal includes a polarity bit which is used to invert the output, if necessary. to produce a signal of the correct polarity. There may be positive and negative threshold circuits, symmetrical about the zero level of the damped sine wave. The peak storage circuit 6 may have positive and negative stores, the sum of the values in these stores being sampled to give the amplitude modulated output. The counter 1 has a capacity equal to the maximum signal expected.
