Abstract: 1,151,014. Two-part coupling. MARCONI CO. Ltd. 16 April, 1968 [28 July, 1967], No. 34933/67. Heading H2E. A cable connector for e.g. coaxial cables, comprises a cable holding nut 3 having one threaded portion 5 of fine pitch to engage the cable 6 and another 4 of coarser pitch to engage a barrel member 1. Due to the difference in pitch, when the nut member is screwed into position the cable 6 will be compressed within the barrel 1 and a firm connection thus made. The barrel and nut members may be of metal. e.g. brass and aluminium, or of plastics material coated with metal, e.g. silver plated. Alternatively, the barrel member 1 may be externally threaded and the nut portion may have said threaded portions both internally threaded (Fig. 2, not shown).

Abstract: 1466446 Reverberation systems SONY CORP 8 Aug 1974 [13 Aug 1973] 35026/74 Heading H4R In a reverberation system a number of signal paths L 1 , L 2 , L 3  are provided between an input and an output with delay means 2A, 2B, 2C in at least one of the paths and with filters 4, 5, at the inputs to some of the paths so that different paths handle signals of different frequency band. As described the delay means 2A, 2B, 2C, are formed by bucket brigade delay devices, with the delay devices in the different paths having different numbers of stages and/or operating at different clock frequencies so that the delays in the paths are different. In addition the delay means is split into sections DA 1 , DA 2 , &c., connected by adders and the input signal of the signal path is applied simultaneously to a number of sections, and the output of one path may also be fed, via amplifiers such as 10 and 11, to the input of another path in addition to being fed to the output adder 3. In alternative systems a multiple echo effect for each frequency band is provided by tapping off the signals between pairs of delay stages and feeding them via additional paths direct to the output, Fig. 5 (not shown), or back to the delay means input Fig. 6 (not shown). Additional filters can be provided in such additional paths (F 1 , F 2 ), Fig. 6 (not shown). An oscillator for providing the shift clock signals comprises three astable multivibrators whose frequencies can be controlled independently or simultaneously Fig. 7 (not shown).

Title: Improvements in or relating to power operated wrenches
IPC: B25B21/02
Filed: 1936-12-31
Abstract: 466,339. Slipping-clutches. INGERSOLL-RAND CO. Dec. 31, 1936, No. 35874. Convention date, Jan. 7. [Class 80 (ii)] [Also in Group XXII] In a power-operated wrench wherein rotational hammerblows are imparted to the tool, a dog-clutch is maintained in engagement by a spring and is positively disengaged and allowed to reengage under pressure of the spring in order to deliver the hammer blows. The shaft 24 of a constant speed reversible electric motor is connected at 25 to a head 43 provided with cam faces 48, 49, Fig. 3, engaging radial rollers 46 carried by the hammer 38. Clutch teeth 40 on the hammer engage wide recesses in an anvil 28 connected to the wrench 35 and a compression spring 51, acting between a ball thrust bearing 52 and the base of the . hammer, maintains the clutch teeth in engagement and the rollers 46 in contact with the cams. When a nut 36 is tightened against the work 54, the rollers 46 ride up the cam faces. 49, as shown in Fig. 3, and raise the teeth 40 out of the recesses in the anvil 28, but when the teeth reach the next recesses, the spring 51 forces them in to deliver a rotational blow to the anvil, a number of successive blows being given to set the nut. As the teeth move forwardly into the recesses, the rollers 46 ride down the cam faces 49 and impart a higher speed of rotation to the hammer than that of the motor-so that the hammer possesses additional momentum before the blow is given. For unscrewing, the motor is reversed and the hammer is raised against the spring 51 by the cam faces 48. The cam faces 48, 49 are straight and the intermediate surfaces 50 have the same curvature as the rollers 46. The anvil 28 rotates in a flanged bearing 32 and the hammer 38 is guided by a central rod 27 engaging a spigot on the motor shaft 24 and fitting in the anvil.

Title: Improvements relating to the cracking of hydrocarbon oils
Filed: 1933-12-29
Abstract: <PICT:0418547/III/1> Oils are cracked by subjecting them to high cracking temperatures e.g. from 850 DEG  F. upwards under pressures of 500--2000 lbs. in a coil 2 and reaction chamber 6 so that 35 per cent of the oil is cracked in a single pass and the resulting cracked products are separated in an evaporator 8 into a liquid heavytar and vapours which are fractionated in a tower 10 into a light final distillate and an intermediate condensate which is then cracked in the vapour phase with a relatively low degree of cracking per pass. This condensate is led through a pipe 20, and if desired through a cooler 20<a>, to the upper end of a chamber 21 where it is vaporized by hot vapours from a cracking coil 41.  Alternatively the condensate may be led directly through a pipe 96 to mix with the cracked vapours in a pipe 47 and the mixed vapours are fractionated in an evaporator 28 from which vapours are led overhead through a pipe 24 to a final fractionator 25, vapours from which are condensed in a cooler 36 separated from gases in a chamber 37 and finally mixed with the final distillate from the tower 10 collected in a separator 19.  The condensate collecting in the tower 25 is led through a pipe 39 to a vapour phase cracking coil 41 and the cracked vapours are passed into the reaction chamber 21 or directly through the pipe 47 into the evaporator 28.  Residues collecting in the towers 8, 28 are passed with reduction of pressure into flash drums 12, 26 the distillates obtained being recirculated to the line 20 and the evaporator 28 or reaction drum 21 respectively.  In a modification, a single tower is employed for fractionating the vapours from both the primary and secondary cracking operations, the coils for which are arranged in a single furnace, while the tar residues from the evaporating zones are combined and flashed in a single evaporator. Specification 409,875 is referred to.
