Patent GB-767037-A (GB)
Title: Polyformals
Inventor: KRISCHAI HANS CEORG
IPC: C07C43/315
Filed: 1954-05-13
Abstract: The invention comprises polyformals of the general formula R1(OCH2OR)n in which R and R1 are aliphatic hydrocarbon groups or hydrocarbon groups, the carbon chains of which are interrupted by oxygen and/or sulphur atoms and n is 2, 3 or 4.  They may be prepared by reacting a monohydric alcohol at elevated temperature with formaldehyde to produce a monoformal having the formula ROCH2OR and reacting the monoformal at elevated temperature in a second stage with a polyhydric alcohol of general formula R1(OH)n to produce the polyformal.  The preferred monohydric alcohols used in the first stage of the process are the C1 to C60 alcohols, ether alcohols, particularly polyethylene alcohols, thio-ether alcohols containing not more than 2 atoms of sulphur per molecule and which may also contain oxy-ether links, and C8 to C13 oxo alcohols.  Particularly preferred monohydric alcohols are 2-ethyl hexanol and 3.5.5-trimethyl hexanol.  The polyhydric alcohols used in the second stage are preferably dihydric alcohols, especially polyethylene glycols and thioether glycols which may also contain thio-ether links. Preferably a catalyst of the acid type, e.g. hydrochloric acid, sulphuric acid, sulphamic acid, p-toluene sulphonic acid, sodium bisulphate, phosphoric acid and acidified ionexchange resins, is used.  An inert liquid hydrocarbon may be used as water entrainer.  Suitable ones are hexane, heptane, benzene, toluene and hydrocarbon mixtures boiling between 40 DEG  and 150 DEG  C. Preferred temperatures for the first stage are in the range 80 DEG  to 120 DEG  C. and in the second stage in the range 150 DEG  to 350 DEG  C.  In an example 2-ethyl hexanol, paraformaldehyde and sodium bisulphate are heated in the presence of a paraffin mixture as water entrainer to give a monoformal which is heated with a polyethylene glycol to give the corresponding polyformal.ALSO:Polyformals having the general formula R1(OCH2OR)n in which n is 2, 3 or 4 and R and R1 are aliphatic hydrocarbon groups and carbon chains of which may be interrupted by oxygen and/or sulphur atoms, may be blended with mineral oils, other synthetic oils such as complex esters and diesters, silicones and polymerized hydrocarbons.  The lubricant so obtained may also contain additives such as anti-oxidants, rust preventives, E.P. agents, pour point depressants and viscosity index improvers.

Title: Process for desulphurising fine iron pyrites
IPC: C22B1/14
Filed: 1926-06-07
Abstract: 254,691. Metallbank und Metallurgische Ges. Akt.-Ges. July 4, 1925, [Convention date]. Sulphur dioxide.-Fine pyrites is desulphurized in two stages; in the first the bulk of the sulphur is removed by being burned in a roasting furnace which may be stationary or rotary, and in the second stage the remainder of the sulphur is burned off by passing a blast of air through it as in the Dwight-Lloyd process. Sintering with resulting agglomeration of the iron oxide may take place in the second stage, water and fuel being added if necessary. A seven storey roasting furnace may be employed, oxygen in any form being introduced into the third or fourth storey, whereby most of the sulphur is burned in the upper storeys while the charge is cooled before it leaves the bottom of the furnace. This enables water to be added to facilitate the agglomeration of the charge, without excessive loss of heat. The gases leaving the Dwight-Lloyd or similar furnace may be introduced into the roasting furnace or mav be worked up separately, e.g. into sulphuric acid.

Title: Improved means of coupling rolling stock
IPC: B61G3/04
Filed: 1928-05-25
Abstract: 311,289. Blair, A. W. June 6, 1927, [Convention date].- Divided on 291,730. Couplings, automatic. - In an automatic knuckle coupling, the knuckle 5, Figs. 1 and 2, is formed as a yoke pivoted on pins 6 and embracing bosses 8, 8<a> on the coupler-head, while the vertically sliding locking-pin 4, Fig. 11, is mainly of rectangular section and is formed with locking-faces 12 which, in the dropped position of the pin, engage faces 13, Fig. 9, on the tails 7, 7a of the knuckle, and with recessed portions 75 which, in the raised position of the pin, allow the tails to swing inwardly for uncoupling purposes. The pin is raised to its upper non-locking position by a link 21 and supported by a lock-set member 30 pivoted on a fixed sleeve 22, through which passes a shaft 25 carrying a cam tripping- member 29, the members 29, 30 falling by gravity into the lock-set position shown. When the coupler-heads on opposing vehicles engage and the knuckles 5 are swung round, a projection 73 at the rear end of the upper tail 7 strikes a trigger member 28 causing the shaft 25 and member 29 to rotate, thereby displacing the lock-set member 30 and allowing the locking-pin 4 to drop. An inclined surface 78 on the pin is adapted, when the pin is raised to its maximum height, to operate a knuckle thrower 35. The rear portion of the coupler-head 1 is extended to form a drawbar 36 slidably arranged in association with a draw-bar spring. By detaching the knuckle 5, pivot pin 6 and locking-pin 4, a false buffing-face 17, Fig. 2, may be accommodated in the recess 2 of the coupler-head, thus allowing the coupling to be coupled, e.g., during a transition period, with a non-automatic hook coupling.

Classes 40(6) and 40(7) [Also in Group XL(b)] A number of similar magnetrons are synchronized by connecting them in parallel by four-arm directional couplers. As shown, two magnetrons Ml, M2 are connected in phase quadrature to the input arms of a coupler DC1 which is preferably of the waveguide 3db. five-slot type. The output arms are connected respectively to a useful load L and to an auxiliary load D1 through a phase-shifter P1 and an adjustable mismatched 'impedance S1. When the outputs of the magnetrons are of the same amplitude and frequency and in the required phase-relationship, there is no output to the auxiliary load Dl, but if these conditions are violated, an output is produced. With the phase-shifter P1 adjusted for minimum output to the auxiliary load Dl, maximum "error power" is reflected back to the coupler and is effective in pulling the magnetrons into step. The Specification describes a circuit for connecting 2<SP>n</SP> magnetrons in parallel. The magnetrons are connected in pairs as shown, the outputs of the couplers being connected in pairs to further couplers and so on.

In a cross-bar exchange in which the calledparty-to-junctor side of a connection is established before the calling party-to-(the same) junctor side of the connection is established, if equipment busy is encountered during the setting up of the calling side connection, the original called side connection is released and a new junctor and called side path to this junctor are selected whereafter a further attempt at completing the calling party-to-(new) junctor connection is made. This allows either the blocking factor to be decreased or the number of junctors to be decreased without an increase in blocking. The sequence of events can be followed from Fig. 2 where IOT represent junctions and LLF, TLF the usual line-link and trunk-link frames of the switching network. A common marker M, when apprised of the calling and called number by a register REG (if necessary with the help of a directory/equipment number translator NG), selects a path I between the called subscriber Sub<SP>1</SP> and a free junctor IOT, 8. Thereafter M attempts to complete a path II between the caller Sub and the same junctor IOT, 8. If equipment busy is encountered, path I is dropped and paths III and IV in that order are set up. A method of breaking down the called side connection by removing battery from the C-wire is described with reference to Fig. 3 (not shown) and a relay chain circuit which controls the break down of the original connection and the setting up of the new connections is described with reference to Fig. 4 (not shown).
