Title: Improvements in or relating to the synthesis of alcohols
IPC: C07C29/16
Filed: 1950-02-03
Abstract: In the oxo-synthesis bottoms remaining after the distillation of the alcoholic products from the hydrogenation stage are themselves at least in part hydrogenated and further quantities of alcohols and ethers obtained.  Conventional reaction conditions are employed in the carboxylation and initial hydrogenation stages of the synthesis although in the latter stage sulfactive catalysts, e.g. MoS2 on active charcoal are preferably used. Carboxylation catalysts used are salts of active metals with high molecular weight fatty acids. Preferably the second hydrogenation is effected with a more active catalyst and the products are then saponified to recover alcohols from esters formed in the process. Preferably the catalyst for the second hydrogenation contains high concentrations of nickel or copper on, e.g. kieselguhr or silica gel and reaction conditions specified for a nickel catalyst are temperatures 300-400 DEG  F., hydrogen pressures 1500-4500 p.s.i.g. and liquid feed rates of 0.4-2.0 v./v./hr.  Saponification is effected with aqueous caustic alkalies at about 300-500 DEG  F., and about 100-400 p.s.i.g.  Two examples illustrate the beneficial results obtained by using a more active catalyst in the second than the first hydrogenation; the catalysts respectively being nickel on kieselguhr and molybdenum sulphide on charcoal. Specifications 629,915, 647,363 and 664,974 are referred to.

Title: An improved gyratory crushing process and apparatus for effecting the same
IPC: B02C2/04
Filed: 1925-02-02
Abstract: 243,926. Symons, E. Feb. 2, 1925. Crushers with gyratory heads. - Relates to gyratory crushing processes of the kind in which material is fed by gravity between a pair of opposed conical crushing members one of which envelopes the other, the members having a gyratory, alternating, approaching, and recessional movement relatively to one another to crush the material and allow it to fall towards a discharge opening. According to the invention, the fall of the particles of material through the crusher is successively interrupted and the material is carried on, and supported by, the inner crushing member towards the outer crushing member, and, after a crushing impact, the particles of material are allowed to fall freely on to the inner crushing member for a further carrying movement and crushing impact. A sizing step, in which the particles pass between extended parallel portions of the crushing members, follows the crushing, the throw of the gyrating member being such as to give the desired size to the product. Fig. 2 shows apparatus for carrying out the process, and Fig. 3 an arrangement for controlling the feed to the crusher. The material falls from the end of a shoot E<31>, which is adjustable vertically to control the feed, on to a flat feed cone D<4> carried at the top of the gyrating cone C<1>, and from thence between the crushing cone C' and the concave E. The spider carrying the concave is adjustable on bolts E<4> relatively to the crushing cone C' and is prevented from creeping relatively to the frame supporting the machine by splitting the frame and clamping it over the spider by bolts. The cone C<1> is mounted on a shaft C<7> eccentrically mounted in a rotating sleeve B which is driven, through a gear wheel B<3> keyed to a collar E<2> at the top of the sleeve B and a gear wheel B<4>, from a main shaft B<5>. The cone C' thus gyrates and rotates about its apex on a spherical bearing A<9> which is lubricated by a gear pump F<1> driven by a crank disc F<3> from the shaft C<7>. The pump circulates oil from a sump F<6> formed in the machine frame, through a conduit F<8>, line F<9> and conduit F<10> to an annular conduit F<11> by which the bearing A<9> is lubricated, a portion of the oil passing from the conduit F<8> by a duct F<20> to the chamber beneath the shaft C' to lubricate said shaft. The lubricant drains back to the sump by a conduit F<13> passing through the gear chamber on its way, a portion passing via a conduit F<14> to the bearing B<6>.

Title: Improvements relating to track signalling systems for railways and the like
IPC: B61L23/16
Filed: 1942-03-09
Abstract: 556,807. Railway track-signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and MACGREGOR, R. M. March 9, 1942, No. 3050. [Class 105] In a railway signalling system employing coded track current characterized by the relative duration of "current" and "no current" intervals as described in Specification 456,781 a decoding relay is employed together with means for causing the energizing current of the relay. to be dependent upon the frequency of - the codecurrent impulses. Fig 2 illustrates the code employed comprising SS code of blank and current inte rvals of equal duration, SL code having a current interval equal to that of the SS code followed by a blank interval of three times that length, and LS code having a blank interval equal to that of the SS code followed by a current interval of three times that length. The SS code current impulses are therefore twice the frequency of the other codes. In a simple application of the invention, not shown, the code supplied to the track operates a code following track relay contact to supply similar code to a decoding relay of ordinary type which responds to the LS and SL codes and to a second decoding relay, the circuit of which is tuned to the higher SS code frequency. In a modification the track relay supplies code current to an ordinary decoding relay for the LS, SL, codes, and to the primary winding of a transformer. A higher voltage is induced in the secondary winding by the higher frequency of the SS code than by the LS, SL codes, and the secondary winding is in circuit with a decoding relay designed to respond only to this higher voltage. Fig. 3 shows an application of this kind to a threeposition signal system to enable a fourth signal to be given. A.C. code current is supplied from source BX, CX, and transformer TI to the railsection 1 over contacts TLS, TSS, TSL of a coding device CT, and the track relay TR is connected to rail circuit through a transformer T2 and full-wave rectifier R3. Relay TR follows the code supplied and supplies similar code from a source B, C over its front and back contacts TRF, TRB to the centrally-tapped primary of a transformer T and to slow-release relays FSR, BSR operating in conjunction with slow pick-up and release relays FSP, SR. The secondary of transformer T supplies a slowrelease relay SSR adapted to respond only to the higher voltage induced by the SS code. The Specification traces in detail the supply of current to the winding SW of signal S to give yellow and green indications in response to SL and LS codes respectively (with track unoccupied) and a fourth YY indication in conjunction with a yellow indication in response to SS code. A red signal is given normally or when the track is occupied. The automatic supply of code current to the adjacent section by coding device CT2 over transformer T3 is also described.
