Abstract: 521,542. Protective cut-out systems. REYROLLE & CO., Ltd., A., and LEYBURN, H. Sept. 20, 1938, No. 27393. Addition to 453,525. [Class 38 (v)] The invention of the parent Specification is modified in that the effective operation of the relays associated with the circuits connected to the section under protection, is dependent on the operation of a master relay N energized in accordance with the fault-current flow in at least one frame-to-earth leakage connection N<3>. Thus, with an external fault, in addition to the safeguard against operation produced by operation of the stabilizing (lock-out) means, a further safeguard is provided by the non- operation of the master relay. The section shown in Fig. 1 is a busbar A to which external circuits B .. D are connected over breakers B' .. D' having trip coils B<2> .. D<2> energized by closure of contacts of a time-lag trip relay L<2>, the energization of which is dependent on closure of contacts M' of a relay M under control of master relay N. The trip circuit is additionally made at contacts L' of a relay L in series with the parallel-connected trip contacts E<4> .. G<4> of relays E .. G, unless any one of the parallel-connected lock-out contacts E<5>.. G<5> of those relays closes and energizes the lock-out relay K, corresponding to an external fault. Relays E .. G have current coils energized by core-balance transformers, as B<4>, in the circuits B .. D, and " voltage coils connected in a neutral-to-earth leakage connection H so as to be energized by the total systemleakage current. The relative directions of the individual leakage currents to that of the system-current determines which way the relays move their armatures, the trip contacts being engaged for incoming fault current and the lock-out contacts for the reverse. The invention is also illustrated, Fig. 2 (not shown), in its application to a modified form of Fig. 1 of Specification 521,541, and including an additional master relay responsive to the neutral-to-earth leakage current, so providing three safeguards.

Abstract: Fluorine-containing organosilicon compounds are prepared by reacting a vinyl silane with a perfluoroalkyl sulphonyl chloride or bromide in the presence of a free-radical initiator, with the liberation of sulphur dioxide.  The products include the novel compounds having the formula:  <FORM:0850228/IV(a)/1> where Rf is a perfluoralkyl radical, X is Cl or Br, R is an alkoxy radical, R1 and R11 are alkyl, alkoxy, fluorine or chlorine, and n is an integer.  Specified initiators for the preparation of the silanes are benzoyl peroxide, di-tert-butyl peroxide and ultra-violet light.  In the Examples:  (1) ViMeSi(OEt)2 is reacted with perfluoromethane sulphonyl chloride to give <FORM:0850228/IV(a)/2> (2) ViMeSiCl2 is reacted with perfluorooctane sulphonyl chloride to give C8F17CH2CHClSiMe Cl2 and <FORM:0850228/IV(a)/3> (3) ViSiCl3 is reacted with perfluorooctane sulphonyl chloride to give C8F17CH2CHClSiCl3 and C8F17CH2CH(SiCl3)CH2CHClSiCl3, and higher telomeric products.  (4) ViSi(OEt)3 is used instead of the ViSiCl3 of Example (3), producing the compound of empirical formula C16H18O3 F17ClSi and the 1,2 telomeric product.  (5) ViMeSiCl2 is reacted with perfluoromethane sulphonyl chloride to give CF3CH2CHClSiMeCl2 and the 1,2 telomer C7H12F3Cl5Si2.  (6) ViMeSi (OEt)2 and perfluorooctane sulphonyl chloride give C8F12CH2CHClSiMe(OEt)2.  The compound may be hydrolysed, or polymerized without direct hydrolysis, e.g. by reaction with zinc oxide.  In Example (7), the 1,1 adduct of perfluorooctane sulphonyl chloride and ViMeSiCl2 is mixed with MeSiHCl2 and hydrolysed to an oil which is converted to a film by heating at 180 DEG C.  A solution in benzotrifluoride is used to treat cotton cloth for water- and oil-repellency.  In (8) the adduct as in (7) is cohydrolysed with Me2SiCl2.  In (9) the 1,1 and 1,2 adducts of Example (1) are hydrolysed to oils and then polymerized by irradiation with beta rays.

IPC: H02P29/00
Filed: 1926-11-05
Abstract: 261,027. Messgerõte Boykow Ges. Nov. 7, 1925, [Convention date]. Electric and magnetic speed indicators.-Relates to a system for regulating an electric current in accordance with the speed of a shaft 2, the current being utilized for producing a torque proportional to the speed or for operating a speed indicator. The shaft 2 rotates electromagnets 1 round a metal cylinder 4 mounted on a second shaft 3 which also carries a coil 6 disposed in the field of stationary magnets 7. Normally, the torque produced by the member 4 is balanced by that produced by the current in the coil 6, but when the speed of the shaft 2 varies the balance is upset and the shaft 3 is rotated to operate a switch S in one or other direction. Normally, a wheel 16 of the switch S engages contacts 17, 18 to energize the electromagnets 8, 9 of a clutch mechanism W. Resistances 29, 30 limit the exciting current of the electromagnets 8, 9 which are energized so that the attractive forces acting on the armature A are neutralized. As soon as the contact pin 10 on the shaft 3 engages one or other contact of the fork 11, current through the corresponding electromagnet 8 or 9 is strengthened and by the consequent movement of the contact wheel 16 the current in the other magnet is cut off. The mechanism W is operated in the appropriate direction to couple a continuously rotating shaft to a contact arm R which rotates over a resistance 25 to regulate the current in the circuit of the coil 6 until the torque produced by the coil 6 restores balance. The balance is obtained after a number of oscillations of the switch S produced by over regulation, i.e. regulation of the current beyond the point of balance. A stationary cylinder 5 is mounted between the magnets 1 and the cylinder 4 to prevent the effect of windage. The Specification as open to inspection under Sect. 91 (3) (a) describes an arrangement, Fig. 1 (Cancelled), wherein the electromagnets 8, 9 are selectively controlled by a simple two-way switch 12 and the rotatable electromagnets 1 are supplied through slip rings 31 and rods 34 embedded in the shaft 2. This subject-matter does not appear in the Specification as accepted.

[Class 119] A breech-block mechanism for a firearm comprises a pivoted bifurcated plate 9, a web 11 uniting the two limbs of the plate, and a firing pin 29, Fig. 7, and extractor 23, both carried by the plate on or adjacent to the web. The breech-block shown pivots on a pin 5 on the bottom plate 1 of the firearm, and on this pin also pivots a combined cocking handle and trigger guard 7. The breech-block is held in its retracted position by a pivoted sear 21 having a tooth 19 adapted to engage a notch 17 in the breech-block. The sear is constantly urged in a clockwise direction by a torsion spring 41 which also acts on a pivoted feed tube 59 forming an extension of a tubular magazine 57 in the butt of the firearm. Assuming the gun to be cocked, a pull on the trigger 43 causes a pawl 45 pivoted thereon to rock the sear to release the breech-block which then rotates under the action of a spring 15 lifting the tube 59 as it rotates, the firing pin eventually firing the cartridge in the chamber. The blow-back pressure on the case serves to return the breech-block to the cocked position. Initial cocking is effected by rotating the trigger guard 7 about its pivot, a projection 63 on the guard serving to engage with and rotate the breech-block. A spring-pressed pivoted member, whose position is controlled by a pin 49 on a thumb slide 53, can be set to hold the sear in a position preventing movement of the breech-block, or to a position clear of the sear.
