Title: Lightning arrester
IPC: H01T1/15
Filed: 1962-05-31
Abstract: 942,240. Lightning arresters. WESTING- HOUSE ELECTRIC CORPORATION. May 31, 1962 [Aug. 2, 1961], No. 21068/62. Heading H2H. [Also in Division H1] In a lightning arrester of conventional design, the ionized gas produced by the non-linear resistance blocks when the arrester develops a fault is used to establish an arc path in the arrester housing and so divert the fault current from the blocks, thus preventing further gas production and the build-up of excessive pressure. The arrester comprises an insulating housing 10 sealed by rupturable metal diaphragms 16 and having metal end fittings 12 provided with baffles 20. The housing 10 encloses two assemblies 22, 24, each comprising insulating tubes 26, 28, 30 arranged in cloverleaf formation between end caps 42. Each tube contains non-linear resistance blocks 34 and a spark gap device 32 comprising a plurality of electrodes in a sealed porcelain tube 36, the various elements in the three tubes being seriesconnected. The tubes 26, 28, 30 have openings 50, 52 at their mid-point, lower and upper ends respectively, and the free space in the housing 10 is filled with an electronegative gas such as sulphur hexafluoride. The circuit through the arrester is completed at each end by a current sensitive element contained in a tube 60 closed at one end by a projectile 62 held in place by the spring arms 66 of a strap 64. When the arrester developes a fault, the blocks 34 produce highly ionized gas which escapes through the openings 50, 52 and envelopes the assemblies 22, 24 to provide an arm path externally thereof. Subsequently, the current-sensitive elements vaporize and the pressure produced in tubes 60 causes the projectiles 62 to strike and rupture the diaphragms 16, thereby allowing gas to exhaust through the baffles 20 and establish an additional arc path exterior of the housing 10. The nature and arrangement of the elements in the tubes 26, 28, 30 may be varied as desired. U.S.A. Specification 2,858,476 is referred to.

Title: Apparatus for the supervision of the speed of vehicles
IPC: G01P1/10
Filed: 1932-07-26
Abstract: 390,389. Indicating group speeds. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-( Vereinigte Eisenbahn - Signalwerke Ges. ; Siemensstadt, Berlin.) July 26, 1932, No. 21086. [Class 106 (iii).] Depending on the speed of a train or vehicle an indicating relay is or is not energized by the instantaneous charge on a condenser at some instant after the train or vehicle has initiated a charging or discharging. For instance, a train closes contact A, Fig. 3, to charge a condenser C fully and then opens that contact whereby the condenser slowly discharges through a resistance R<1> ; after an interval, depending on the speed of the train, the train closes a spaced contact B whereby the condenser discharges through a set of relays R<11>, R<12>, R<13> adjusted to respond to different condenser potentials so that an indication of the speed is given by the number of relays which respond. Fig. 5 shows an arrangement in which only one contact is used. The train maintains the contact A for a certain time in the dotted position whereby the condenser C is slowly charged through the resistance R<4> ; when the contact is freed it returns to the full-line position and the condenser discharges through the relay S. The condenser and relay apparatus may be fitted on the locomotive, two contacts on the locomotive being successively actuated by a single track abutment, or two track abutments successively actuating a single locomotive contact.

Abstract: 773,335. Labelling machines. FAIREST, Ltd. M. July 14, 1955 [July 21, 1954], No. 21209/54. Class 73. Body and neck labels 29, 30, Fig. 6, are applied to articles such as bottles 12, Fig. 2, by a machine having a driving member 15, Fig. 3, with projections 14 for moving the bottles in a circular path, a delivery head 16 rotating above and about the - same axis as the member 15, and cam controlled vertical arms 25 and levers 87, carried by the head 16, carrying pads 76, 89, which take labels by suction from transfer means, such as a rotary transfer member 21, and apply them to the bottles which are then fed past wiping means such as brushes 109, 110. The machine shown in plan in Fig. 2 is similar in many respects to that disclosed in Specification 746,506, the bottles on a conveyer 11 being spaced by a worm 13, being taken from the conveyer by the projections 14, and being returned, after labelling, to the conveyer by the combined movements of a rotary table 19 and a conveyer 21. The labels 29, 30, are fed to the gummed faces of an intermittently rotating pick-up box 24 and are taken from the box by suction pads on the arms 23 of the transfer member, these arms on continued rotation serving to take the labels into the paths of the pads 76, 89. As shown in Figs. 3 and 4 the head 16 consists of a sleeve 42 keyed to a shaft 47, the shaft being mounted in bearings 49 of a housing 50 which can be raised and lowered by a screw and nut device 53, 54. Rotation of the head is effected by the engagement of a long gear 41 thereon with pinions 40 on shafts 38, which shafts are geared at 37 to a drive for the member 15. Within the sleeve are mounted vertical pivots 46 for the arms 25. Each arm is urged towards a stop pin 44 by a spring 66 and each is acted upon by a bell crank 67 having a roller 68 engaging a fixed cam 71. Another fixed cam 96, see also Fig. 6, serves to operate a bell crank 88 which is pivoted at 88A to the body 73 of the arm and which carries the pad 89 on a pivot pin 90. The body 73 has a bore in which a tube 78 carrying the pad 76 is adjustably mounted and which is connected by tubes 59 to a port 58 of a rotary valve plate by which the pads are connected alternatively to a source of vacuum and to the atmosphere. The cams 71, 96, are so designed, see Figs. 4 and- 6, that the arms 25 move towards the arms 23 at the transfer position, then move in the opposite direction to provide a space for the reception of a bottle, and subsequently move towards a bottle to apply the labels. An additional movement is given to the bell crank 88 by the cam 96 to apply the neck label 30. After labelling the arm and bell crank are returned to their initial positions the pad 89 being swung to a correct label-receiving position during this movement by the engagement of a lip 99 thereon with a shoulder 100.

Title: Improvements in or relating to the production of liquid explosive nitric esters
Inventor: ALLAN WILLIAM GORDON
Filed: 1952-08-27
Abstract: A method of treating a stream of spent liquid explosive nitric ester wash-waters comprises emulsifying said wash-waters with a stream of a non-explosive liquid of aromatic nitro-hydrocarbon character consisting at least predominantly of a non-explosive aromatic mono-nitrohydrocarbon or mixture of such mono-nitrohydrocarbons liquid at ordinary temperatures and arranging the proportions of said non-explosive liquid of aromatic nitro-hydrocarbon character and said wash-waters so that as a result of their emulsification the wash-waters are substantially freed from the liquid explosive nitric ester and that the resulting solution of the liquid explosive nitric ester in said non-explosive liquid is of a liquid explosive nitric ester concentration below that necessary for it to be capable of propagating a detonation, and thereafter permitting the resulting stream of emulsion to separate into its aqueous phase consisting of extracted spent wash-water and its non-explosive phase consisting of a solution of said liquid explosive nitric ester in said non-explosive liquid of aromatic nitro-hydrocarbon character. The non-aqueous phase may be re-emulsified with further spent liquid explosive nitric ester wash-water.  The non-aqueous phase, neutralized with aqueous alkali if acid, may be used in blasting explosive compositions.  Non-explosive aromatic mono-nitro-hydrocarbons mentioned are o-nitrotoluene and liquid mixtures of mononitroxylenes.  The drawing of the apparatus (not shown) includes storage tanks for liquid explosive nitric ester wash-waters and non-explosive liquid of aromatic nitro-hydrocarbon character, a centrifugal pump for effecting emulsification and a separator.  The solution of the nitric ester in the non-explosive liquid is recycled until the nitric ester content reaches the desired value.  In an example nitroglycerine wash-waters are extracted in the above apparatus with o-nitrotoluol and the o-nitrotoluol phase is neutralized with aqueous sodium carbonate solution.  The o-nitrotoluol is incorporated in a blasting explosive composition (see Group XXI).
