Title: Improvements in or relating to hydraulic lifting apparatus
IPC: F15B11/20
Filed: 1970-06-16
Abstract: 1285150 Shovelling machines SOC ANON POCLAIN 16 June 1970 [18 June 1969] 29088/ 70 Heading E1F [Also in Divisions B8 and Fl]  A jib arm 2 Figure 1 is lifted about a pivot 3 carried by a fixed structure 1 by extension of a hydraulic jack 4 having its rod end pivoted at 7 to the jib 2 and having its cylinder end pivoted at 8 to an element 5 which is itself pivoted at 6 to the structure 1 and is actuated by a hydraulic jack 9 pivoted thereto at 11 and pivoted to the structure 1 at 10; supply of fluid to one or other end of jack 9 being determined by the fluid pressure required to extend jack 4 and hence arm 2 whereby under light load jack 9 is retracted so that element 5 assumes the position shown in broken line the jack 4 extends at high speed whereas under heavy load jack 9 is extended so that element 5 assumes the position shown in broken line and the jack 4 extends less quickly. To extend jack 4 under light load a 3-way valve 13 Figure 2 is moved to the left to connect a pump 12 to a supply line 16 having a branch line 18 leading to a spring-biassed piston 19 at one end of a 3-way slide valve 20 which is urged by its spring 21 so as to connect a pump 22 to the rod end of jack 9 which thus swings element 5 to the full-line position. When the extending jack 4 becomes loaded the pressure in line 18 overcomes spring 21 and valves 20 connects the pump 22 to the head end of jack 9 which is thus extended and so swings element 5 to the broken line position. To lower the jib arm 2 valve 13 is moved to its extreme right position whereon lines 16, 18 are connected to a reservoir 15 and jack 9 is retracted so that element 5 assumes the full line position and jack 4 retracts at high speed. In a modification adjustment of jack 9 and hence of elements 5 effected over a range of pressures in the head end 4a Figure 3 of jack 4 is effected by a pressure pick up 37 comprising a spring- biassed piston 38 subjected to fluid pressure in the feed line 29 of extending jack 4. At low pressure a rod 42 of piston 38 pivots a lever 43 counter-clockwise about 11 to move a 3- way valve 34 to the left and thus connects a branch 32 of a supply pressure line 32 to a line 35 to retract jack 9; fluid being exhausted from 9b through a line 36 valve 34, a line 33, check valve 49 a valve 50 held open by pressure in line 32 and a return line 30. Retraction of jack 9 pivots lever 43 clockwise about an axis 44 and thus returns valve 34 to the closed position whereon lines 32, 33 are blocked by valves 48, 50. An increased pressure in line 29 thence in line 40 extends rod 42 which pivots lever 43 clockwise about 11 which moves valve 34 to the left to connect line 32 to chamber 9b thereby extending jack 9 and hence pivoting element 5 clockwise until such time as the lever 43 recloses valve 34 whereon element 5 is held fixed.

Abstract: 1,026,279. Telegraphy. SIEMENS & HALSK A.G. July 15, 1964 [July 16, 1963], No. 29141/64. Heading H4P. In a multiplex exchange in which a called station responds only when there is a simultaneous marking on a preset number n of the m channel link, each of the subscribers is triggered by a pulse fed to all the subscribers in series. If a subscriber has data to transmit the trigger pulse is delayed before passing to the next subscriber. Alternatively, each subscriber delays the trigger pulses so that the subscribers are enabled in regular succession. The trigger pulse from the last subscriber feeds the first subscriber. The embodiment refers to an exchange comprising cores which are set up by a dialling subscriber to cause n channels to be marked by each data pulse. The distant receiver includes a gate which passes a signal only when those n channels are marked. Each bit is transmitted as a short pulse at the beginning and end of the bit time.

Title: Derivatives of mitosane compounds
Inventor: MATSUI MASANAO
IPC: A61K31/395
Filed: 1965-07-09
Abstract: Novel antibiotic derivatives of mitosane compounds of the Formula I <FORM:1115983/C2/1> wherein X is methoxy, amino, aliphatically or aromatically mono- or di-substituted or heterocyclic amino and -COR is substituted acyl or, when X is other than amino, unsubstituted acyl, provided that, when X is methoxy, R is not a lower alkyl group of 1 to 5 carbon atoms or the phenyl radical, are prepared by treating a mitosane compound differing from the desired product in having a H atom instead of the -COR radical with an organic acid having the formula RCOOH in the presence of a dehydration-condensation agent of the type R3N = C = NR3 where R3 is an aliphatic or aromatic hydrocarbon radical, R being as above defined.  The dehydration-condensation agent may be dicyclohexylcarbodiimide or ditolylcarbodiimide, the reaction advantageously being effected in a solvent.  Compounds of Formula I above include those wherein X is an aliphatically mono- or disubstituted amino (e.g. methyl-, ethyl-, propyl-, isopropyl- or n-butylamino, or diethyl-, dipropyl-, diisopropyl- or di-n-butyl-amino), aromatically mono-or di-substituted amino (e.g. phenylamino, diphenylamino, chlorophenylamino, bromophenylamino, methylphenylamino, dimethylphenylamino or phenylethylamino) or heterocyclic amino (e.g. pyridyl); -COR may be substituted acyl (e.g. haloalkylcarbonyl, dihaloalkylcarbonyl, alkanoylaminoalkylcarbonyl, alkanoylalkylthioalkyleneaminoalkylcarbonyl, alkenylalkenylcarbonyl, nitrophenylcarbonyl, dinitrophenylcarbonyl, halophenylcarbonyl or dihalo - phenylcarbonyl, especially acetylglycyl, bromoacetyl, chloropropionyl, nitrobenzoyl, dinitrobenzoyl, sorbyl, acetylmethionyl, chlorobenzoyl, dichlorobenzoyl, iodobenzoyl, fluoroacetyl, dichloroacetyl, or chloroacetyl) or unsubstituted acyl.
Patent GB-366108-A (GB)
Title: An arrangement for the selective distance protection of polyphase lines
IPC: H02H1/00
Filed: 1930-09-30
Abstract: 366,108. Protective cut-out arrangements. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Sept. 30, 1930, No. 29265. Convention date, Jan. 23. [Class 38 (v).] Selective distance protection of a polyphase line R, S, T is obtained by connecting resistance relays r, t in two of the phases R, T, and providing a momentarily-acting overload relay s in the common return of the current coils e of the relays r, t. The voltage windings fare connected across transformers b and the relay s, when operated, changes the winding f of relay r from phases R, T to phases R, S, and removes at m a short-circuit for the coil g of the relay t. The latter coil when sufficiently energized closes at k a short-circuit for the coil g of the relay r, the coils g, on excess current, acting to initiate the time-release of relays r, t. On a shortcircuit occurring between phases R, T, the overload appears in both current coils e and in coil g of relay r, which is also energized by the voltage across the faulty phases. The relay r therefore responds and closes the trip-circuit at h. The relay r also responds on a short between phases R, S, because in this case the relay s receives the overload and changes over the connection of the winding f of relay r to the faulty phases R, S. On a short occurring between phases S, T, the overload appears in coil e of relay t and coil s which removes at m the short-circuit of the coil g, whereupon the relay t, the coil f of which is fed by the faulty phases, closes its contacts i. A short between all phases causes r, s to respond, relay s inserting the coil g of relay t which coil g closes the switch k to cut out the coil g of relay r so causing the latter to return to its inoperative position and leaving the relay t to close the trip-circuit. The relay s may be connected in the phase S and the invention is stated to be applicable also to more than three phases.

Filed: 1952-12-19
Abstract: The invention comprises dodecahydrophenanthrenes of the general formula <FORM:0763208/IV(b)/1> wherein the 7-position is substituted by a bivalent group convertible to keto by acid hydrolysis or by a pair of univalent groups together convertible to a single keto group by acid hydrolysis, and decahydrophenanthrenes of the general formula <FORM:0763208/IV(b)/2> wherein the 7-position is substituted by a single univalent group convertible to keto by acid hydrolysis, and a process for the preparation thereof by heating 4b-methyl-1,4-dihydroxy-7-keto - 1,2,3,4,4a,4b,5,6,7,9,10,10a - dodecahydrophenanthrene with a ketalizing or enolizing reagent in the presence of an acid catalyst.  Examples of bivalent groups are cyclic ketal and cyclic thioketal groups such as ethylenedioxy, ethylene dithioketal and ethylene hemithioketal groups, examples of pairs of univalent groups are the non-cyclic ketals such as dimethyl ketal, and examples of univalent groups are the enol ether groups such as ethyl enol ether.  Suitable ketalizing and enolizing reagents mentioned are alcohols and glycols, particularly ethylene glycol, and a suitable acid catalyst is p-toluene sulphonic acid.  The reaction with ethylene glycol is preferably carried out in ethylene dichloride so that the water formed in the reaction is distilled off as an azeotrope with the ethylene dichloride.  The above process may be modified in that the 4b-methyl-1,4-dihydroxy - 7 - keto - 1,2,3,4,4a,4b,5,6,7,9,10,10a-dodecahydrophenanthrene is prepared by a process claimed in Specification 736,307.  An alternative process claimed for the preparation of 4b - methyl - 1,4 - dihydroxy - 7 - ethylenedioxy - 1,2,3,4,4a,4b,5,6,7,8,10,10a - dodecahydrophenanthrene comprises reducing the corresponding 1,4-diketo- or 1-keto-4-hydroxy-compound with lithium aluminium hydride, e.g. in tetrahydrofuran solution.  This process may be modified in that the 1,4-diketo- or 1-keto-4-hydroxy-substitute reactant is prepared by a process described in Specification 763,207. Three isomers of 4b-methyl-1,4-dihydroxy-7-ethylenedioxy - 1,2,3,4,4a,4b,5,6,7,8,10,10a - dodecahydrophenanthrene are referred to, having the melting points 189 DEG , 175-176 DEG  and 198-199.5 DEG  C.
