Abstract: 250,245. Compagnie Generate d'ElectricitÚ. March 31, 1925, [Convention date]. Fusible cut-outs. - The base 1 has an elevated part 5 forming a central space 6 and apertured at 7 to receive the contact 8 which is connected with a terminal 10. Above the part 5 is a contact plate 14 connected with a terminal 10<1> and secured by means of a screw 15 to the part 5. The plate 14 is perforated to receive any of a range of fuse cartridges, and the contact 8 is formed with a rim 11 beneath which engages a spring 12 pressing it upwards. Secured to the part 5 is a plate 2 which is apertured to receive the fuse of a particular rating, a series of plates 2 with varying apertures, Fig. 4, being provided. The fuse carrier comprises a cap 18 and cartridge 17 provided with lugs 19, 19<1> which vary in dimensions according to the fuse rating and the difference between the sizes being always greater than the permissible movement between one plate 2 and its cartridge so that a fuse of higher rating cannot be substituted. A cavity in the cartridge contains inert material 22, and the fuse wire 21, which is soldered at 23 to a metal casing 24 and to a sector 28 moving about a pin 27 which is riveted to the metal end 25 of the cartridge. The end 25 comprises two tongues 26. 26<1> located in grooves in the body of the cartridge and covering the upper faces of the lugs 19, 19'. Normally when the cartridge is ready in place the sector 28 is held by the fuse in a position at 180 degrees to its position of rest, and when the fuse blows the sector is rotated by a light spring 29 to its position of rest. The cap 18 has a glass disc 31 half of which is opaque and half transparent and the sector, which is preferably coloured so as to be observable at a distance, moves from under the transparent to under the opaque part when the fuse blows. To insert a cartridge into place it is necessary to get the lugs 19, 19' under the level of the plate 14 and then rotate the cartridge so that the spring 12 presses the metal-covered upper parts of the lugs against the plate 14.

Title: Ground fault interrupter
IPC: H02H3/33
Filed: 1974-02-28
Abstract: 1448934 Protective cut out systems CUTLERHAMMER EUROPA Ltd 28 Feb 1974 [28 March 1973] 9182/74 Heading H2K A ground fault responsive system has a corebalance transformer 10 having a winding 14 providing a ground fault signal which is fed to a detection circuit which responds to the component of the signal which is in phase with the voltage of the power lines to which the detection circuit is also connected. A field effect transistor Q3 provides a load for the half cycle of the output of the winding 14 to which an amplifier 22 does not respond and a capacitor C3 has about 1 volt across it under healthy circuit conditions and its bias on a transistor Q2 is such that it will not conduct. With a resistive fault on the lines the potential at the base of Q2 will fall to permit conduction with consequent triggering on an SCR Q1 in series with a circuit breaker trip coil CBT. The voltage at the L.H. end of C3 depends on the voltage across Zener diodes ZD1 and ZD2. A push button PB provides for testing of the system. In the event of an inductive or capacitive fault the amplifier OA has an output 90 degrees out of phase with the phase voltage across C3 which integrates the pulse to ensure that Q2 does not conduct. In Fig. 3 (not shown) a single phase 3 wire system has additional capacitor and transistor circuitry so as to respond to resistive earth faults in either of the line conductors. A diode D3 provides a hold in feature and a varistor VR2 provides transient voltage protection for the load circuits on the power line.

[Also in Group XL (b)] The delay line in a travelling-wave tube is constituted by inwardly curving interdigitating fingers 8, 9 fixed to a longitudinal bar 7, the electron beam passing within the space enclosed by the fingers. The fingers may be formed by bending over straight fingers attached alternately to either side of the bar, or by securing to the bar identical rings, the rings being split alternately on opposite sides of the bar. They may be formed by securing the bar along a helix and splitting the convolutions on alternate sides of the bar, or by the direct machining of the bar. The fingers may enclose a space of circular, oval or rectangular cross-section. The fingers themselves may be of circular, rectangular, or triangular cross-section. The fingers may be extended by straight portions 10, Fig. 7, extending along the flanks of the bar 7. A quarter-wave slot may be formed in the bar, the slot opening into the space enclosed by the fingers. Transverse slots may be formed between the fingers. The electron beam may completely encompass and diffuse about the conductors of the line. The beam may pass between an inner conductor and the line. The envelope of the tube may be of metal or it may be metallized or coated with graphite, or an outer conductor may be provided outside the envelope, for example by the support of a magnetic focusing device. Air or water cooling ducts may be formed in the bar. Preferably the bar is mounted in the tube against the envelope to aid the dissipation of heat. The fingers of the delay line nearest the electron gun are preferably made of refractory metal. Specification 699,893 is referred to.

Patent GB-905317-A (GB)
Title: Improvements relating to absorption and desorption processes using molecular sieves
Filed: 1960-03-17
Abstract: Straight chain hydrocarbons are separated from mixtures of hydrocarbons containing a major proportion of normally solid hydrocarbons with more than 20 carbon atoms per molecule, especially 40 or more carbon atoms per molecule, by contacting the mixture in a fluid, preferably liquid, phase with a molecular sieve, and subsequently desorbing the absorbed material in the liquid phase by means of a straight chain hydrocarbon of lower molecular weight than the absorbed hydrocarbons.  The process may be employed for the separation of straight-chain hydrocarbons from waxes, and is preferably carried out below 450 DEG C.  The mixture may be dissolved in a solvent, the molecules of which are larger than the sieve pores, for example an aromatic compound such as benzene or toluene.  The desorption may be carried out at or near the boiling point of the desorbing liquid, which may be a straight chain paraffin in the C5-C10 range, for example in a soxhlet apparatus.  In examples employing a 5   molecular sieve ndotetracontane was absorbed from benzene and desorbed with refluxing n-heptane, paraffin wax was absorbed from benzene and desorbed with refluxing n-heptane, and p microcrystalline wax was absorbed from toluene and desorbed with refluxing n-heptane.  In the last example, the major part of the wax was not absorbed.

Title: Purification of lactams
Inventor: WINTERSBERGER KARL
Filed: 1962-03-14
Abstract: Lactams having five to eight membered rings and in which the methylene group may have one or two hydrogen atoms replaced by C1-C3 alkyl groups are purified by heating the lactam to a temperature above its melting point, but not more than 30 DEG C. above said point, in the presence of 0.5 to 10%, preferably 2 to 4%, by weight of sulphur trioxide, or oleum containing at least 2% by weight of free sulphur trioxide, whilst mixing, leaving the mixture at this temperature for 10 minutes to 3 hours, neutralising if necessary and distilling under reduced pressure. The lactams to be purified may have been produced by various methods but the process is especially applicable to lactams obtained by the gas phase catalytic rearrangement of cyclic hetoximes. It is preferred to use 2 to 4% by weight of oleum containing 23 to 65% of free sulphur trioxide and to neutralise the sulphuric acid with alkali after heating when more than 3% by wt. of oleum is used. The lactam and oleum may be mixed below the melting point and then heated but it is preferred to mix them in the liquid state. Any conventional method of lactam purification, e.g. treatment with potassium permanganate, may be used prior to and/or after the process of the invention. The examples relate to the purification of caprolactam.
