Filed: 1924-10-13
Abstract: 223,251. Diacoyanni, C. Oct. 13, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Press-button fasteners.-A press button fastening is constructed with a locket member adapted to receive the stud member from either side, the stud engaging a split spring ring or equivalent part mounted in or formed integrally with the socket. The arrangement is such that release can only be affected by a straight outward pull when the stud is inserted at one side of the socket but can also be affected by an oblique pull when the socket is so arranged that the stud is engaged in the other side. Figs. 2 and 5 show a socket 1 in which a split spring ring 4 is loosely retained by lugs 4<1> thereon engaging slots in an upstanding central part 2 which is flanged over the ring. When the stud part 6 is inserted at the side shown in Fig. 5, release by tilting is prevented by a shoulder 11<1> on the stud member bearing on the rim 12 of the socket. In a modification, Fig. 7, a plain split ring 8 is retained between the upturned flange 2 of the socket part 1 and a flanged disc with radiating arms 9<1> which are bent and curved over with the run of the socket. In another modification, Fig. 10, the upstanding centre part of the socket is slit and the top bent inwards and curled over.

Title: Tendons
IPC: B29C48/15
Filed: 1971-04-19
Abstract: 1341632 Encased strands F A LANG 19 April 1972 [24 March 1970] 24672/71 Heading D1T A multiple wire strand 1 is surrounded by a corrosion inhibitor 3 and an outer seamless plastic jacket 4, the thickness of the corrosion inhibitor between the strand 1 and the jacket 4 being at least 1 mil, and the corrosion inhibitor having a worked penetration value within the range 85 to 385 at 77F as determined by the American Society for Testing and materials D217 method. The corrosion inhibitor has a grease-like consistency and may, for example, be a fibroustextured barium soap grease with a paraffinic base oil or a buttery-textured lithium soap grease with a naphthenic base oil. The plastic jacket may be a polymer or copolymer of propylene. High molecular weight polyethylene is stated to be paticularly useful. The strand 1 may be of high tensile steel and may have on its outer surface a thin coating of a polymer selected from the group consisting of tetrafluoroethylene and copolymers of tetrafluoroethylene with 5 to 35% hexafluoropropylene.  Fig. 3 (not shown) illustrates how the cable may be made by pulling the strand 1 through a pressure chamber (5) into which the corrosion inhibitor 3 is fed under pressure. As the cable passes out of the chamber (5) a circular die 8 smooths and shapes the grease-like corrosion inhibitor 3 into a circular incasement about the strand. The incased strand is then passed through the throat of a tubing die (10). Molten thermoplastic polymer 11 is extruded as a tube around the corrosion inhibitor. The rate of travel of the strand and the rate of extruding of the thermoplastic polymer is adjusted so that there is a necking down (12) of the polymer at a distance from the die (10) that will permit the cooling of the polymer to a temperature below the vaporization temperature of the corrosion inhibitor 3. By this process the plastic polymer shrinks and forms a tight seamless plastic jacket 4 around the inhibitor 3. The finished product then passes through cooling means such as a water cooling tank (13).

Abstract: 728,430. Pulse code modulation; pulse circuits. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. Sept. 10, 1953 [Oct. 13, 1952], No. 25097/53. Classes 40 (5) and 40 (6). In a coded pulse system, binary single-digit code pulses are transmitted or suppressed according to the polarity of the output of a comparator supplied with the signal after differentiation and an integrated version of the output pulses, the receiver being constituted by means for performing a double integration of the received pulses. At the transmitter the signal is applied to a differentiating circuit 202, the output from which is applied to a comparator 208 which determines whether or not pulses from a master generator 210 are passed by the valve 212 to the flip-flop pulse regenerator 213, 214 and thence to the outgoing line 223. The other input to the comparator 208 is the output of an integrating circuit 230 fed with positive and negative pulses, from circuit 224, which correspond to the negative and zero pulses respectively at the output conductor 223. The time constants of the differentiating network 205,206 and integrating network 233, 234 are, for example, T1 = 1/4F o  and R2 = 5/F respectively, where F o  is equal to the width of the signal frequency band and F is the pulse recurrence frequency. The circuit 224 comprises two valves 225, 226 to the control grids of which are fed the negative pulses at conductor 223, the suppressor grid of valve 226 being fed with the regular positive pulses from generator 210. When a negative pulse occurs at the control grids, valve 225 feeds a positive pulse to the integrator 230, the valve 226. having zero output due to the conjunction of a negative control-grid pulse and a positive suppressorgrid pulse. When zero pulse occurs at the control grids the positive pulse at the suppressor grid of valve 226 produces a negative voltage to be fed to the integrator. At the receiver, the pulses are regenerated and after conversion to the positive and negative form are passed to the input of an integrating network having a time constant T1, the output from which feeds a second integrating network having a time constant T2. The output from the latter is passed through a low-pass filter to the signal utilization device, Fig. 3 (not shown).
