Title: Improvements in or relating to automatic railway vehicle couplers having lock-set mechanism
IPC: B61G3/18
Filed: 1958-11-11
Abstract: 887,726. Railway vehicles automatic couplers and lock setting mechanisms. NATIONAL MALLEABLE & STEEL CASTINGS CO. Nov. 11, 1958 [Nov. 18, 1957], No. 36217/58. Class 103(5). An automatic coupling having fixed jaws 7, 8, a buffing wall 9, and a horn guide 11, has a lock setting mechanism for a lock 15, which lock comprises a stem 16 extending through a guide opening 13 of a lug 20 and providing legs 17, 18 with an opening 19 therebetween. The lock is urged forwardly by a spring 21 confined between the lug 20 and a shoulder formed on the lock at the juncture of the legs, and is forwardly supported and guided in forward motion by a lug 24 on the jaw 8 which may enter a groove 25 in the lock and may also act as a lock limit stop. The lug 24 also acts as a stop for limiting the rotation of a lock operating lever 26 which in turn limits the forward movement of the lock. The lever 26 which is pivotally supported by a pin 27 in the head, comprises a handle 28, an extension 31 extending through the opening 19 in the lock and having a surface 31B engaging the lug 24, and an extension 30 cooperating with a pawl 32 slotted on the pin 27. The lever 26 may move and be moved by the lock 15. In setting the lock so that it will not operate when buffing, the lever 26 is rotated anticlockwise to push back the spring 21 and carry the extension 30 rearwardly into engagement with a cam surface 43 on the pawl 32. The pawl is lifted as the extension 30 engages the cam surface 43 and travels about the pin 27 as centre, and when the extension passes to the rear of the surface 43 the pawl drops under gravity in front of the extension which then engages a surface 44 on the pawl. Fig. 5. If the force on the lever 26 and spring 21 is discontinued the pawl will swing forwardly if not held back by the surface of the jaw 8 of the mating coupler, Fig. 6. In the original Fig. 5 position, however, the surfaces 35 and 47 co-operate to hold the lock setting position. When the jaw 8 of the mating coupler moves away as after buffing, the pawl follows and is cammed upwardly by the surface 35, Fig. 6, thereby causing the extension 30 to move downwardly relative to the surface 44 until it may round the corner 49 and pass into the notch 52, thus permitting the pawl to drop back and the lock 15 to move forwardly into the Fig. 7 position. To move from the lock set position, Fig. 5, to the coupling locked position, it is only necessary to raise the pawl by a handle 50 so that the lock is thrust forwardly by the spring 21 to its locking position and the lock setting mechanism released to snap into the position of Fig. 7. In a modification the pawl is provided with a downwardly projecting cam surface which takes the place of the cam ridge 39, and operates in an opening in the head having cam and stop surfaces.

IPC: C07D295/03
Filed: 1946-12-07
Abstract: Substituted allylamines of the general formula <FORM:0624117/IV (b)/1> or salts thereof, in which R1 and R2 are aryl, aralkyl or cycloalkyl groups which may be further substituted by alkyl or alkoxy groups; R1 and R2 may be identical provided that both are not aralkyl groups; R3 is hydrogen or alkyl; R4 is hydrogen, alkyl or aryl (substituted or unsubstituted as above); R5 and R6 are alkyl or aryl, or -NR5R6 may denote the piperidino-, pyrolidino- or morpholino-groups; are prepared from the corresponding N-disubstituted - g  : g  - disubstituted - g  - hydroxy-propylamines or salts thereof by removing the elements of water by known methods for the conversion of tertiary alcohols to olefines.  The allylamines may be converted into the corresponding propylamines by reduction under mild conditions. When R1 or R2 are aralkyl or cycloalkyl groups the product of dehydration is sometimes an isomer in which the double bond is attached to the a -carbon atom.  In examples: (1) 3-n-piperidino-1 : 1-diphenylpropan-1-ol hydrochloride is refluxed with a mixture of concentrated hydrochloric acid and glacial acetic acid to give 3-N-piperidino-1 : 1-diphenylprop-1-ene hydrochloride which is reduced with hydrogen and a hydrogenation catalyst to give 3-N-piperidino-1 : 1-diphenylpropane; (2) 3-dimethylamino-1 : 1-diphenylpropan-1-ol is treated as in (1) to give 3-dimethylamino - 1 : 1 - diphenylprop - 1 - ene and 3-dimethylamino-1 : 1-diphenylpropane; (3) 3-diethylamino - 1 : 1 - diphenylpropan - 1 - ol hydrochloride is treated as in (2) to give the corresponding ethyl derivatives; (4) 3-N-pyrrolidino - 1 : 1 - diphenylpropan - 1 - ol is treated as in (1) to give 3-N-pyrrolidino-1 : 1-diphenylprop - 1 - ene and 3 - N - pyrrolidino-1 : 1-diphenylpropane; (5) the corresponding morpholino derivatives are used in the process of (4) to give analogous products; (6) 3-di-methylamino - 1 : 1 - diphenylbutan - 1 - ol hydrochloride is treated as in (1) to give 3-dimethylamino - 1 : 1 - diphenylbut - 1 - ene and 3 - dimethylamino - 1 : 1 - diphenylbutane; (7) 3 - diethylamino - 1 : 1 - di - p - tolylpropan-1-ol hydrochloride is treated as in (1) to give the corresponding derivatives; (8) 3-diethylamino - 1 - cyclohexyl - 1 - phenylpropan - 1 - ol is used as the starting material in the process of (1); and (9) p  3-diethylamino-1-benzyl-1-phenylpropan-1-ol hydrochloride is treated as in (1).  Specification 624,118 is referred to.
Patent GB-1484198-A (GB)
Title: Data stores
IPC: G11C17/02
Filed: 1974-08-19
Abstract: 1484198 Data store SIEMENS AG 19 Aug 1974 [21 Aug 1973] 36351/74 Heading G4C In a data store in which storage element M11-Myx is selected by connecting, in response to address signals az, as, the ends of a selected row line zl-zx and a selected column line sl-sy to the poles of a constant current source I which is energized by a later occurring timing pulse t so that current flows through the selected element to read out data, each row line zl-zx is connected via a normally conductive switch T1 to a voltage source, the switch being rendered non-conductive by the timing pulse t. The arrangement establishes, when a row is selected, a current equal to that provided by the constant current source in the selected row line so that the row line capacitance is charged and read out occurs with minimum delay on the occurrence of the timing pulse. Storage elements, e.g. transformers M11- Myx of which only the primaries are shown, are selected by decoding row address signals az to select one of the transistors TZ1-TZx and connect a row line zl-zx to earth, and column address signals as to select one of the transistors Tsl-Tsy and connect a column line sl-sy to a constant current source I which is however not energized until the later occurrence of a timing pulse t. However immediately one of the row line transistors TZ1-TZx is selected current flows through the corresponding diode D1-Dx and transistor T1 which is conductive. The resistors R1, R21-R2X are chosen such that the current is equal to that from source I. Thus when the timing pulse t occurs and transistor T1 is switched off and source I energized the row line capacitance is already charged and read out, due to the current flowing from source I via a column line, a transformer primary, and a row line, is immediate. The row and column lines are connected to monitors PZ, PS which check that only one row and column line is selected at any one time, resistors WZ1 and Ws1-Wsy ensuring that the voltage at the monitored points of non-selected lines is significantly different from that of selected lines. An arrangement including diode Da, a transformer, and transistor Ta is also provided so that should a fault develop, e.g. the selected column line is broken, excess voltage is not developed and a fault signal A is producedi

Title: Improvements in or relating to variable pitch marine screw propellers
Inventor: CHADWICK JAMES ALEXANDER
IPC: B63H3/04
Filed: 1954-12-16
Abstract: 821,824. Marine variable pitch propellers. SLACK & PARR (MARINE) Ltd. Dec. 15, 1955 [Dec. 16, 1954], No. 36411/54. Class 114. In a marine variable pitch propeller having three or more blades and in which pitch variation is effected by a control rod sliding in a hollow propeller shaft and carrying a crosshead linked to a crank arm or crank pin on the propeller blade root by a link capable of swinging movement about a centre fixed on the crosshead, a hub 14 bolted to a hollow propeller shaft 12 accommodates a crosshead 35 mounted on the end of a control rod 11 movable in the hollow shaft to displace the crosshead 35 along rods 33 supported between front and rear walls 34, 32 of the hub. The crosshead has a face 38 opposite each propeller blade root 21 the roots being secured to crank discs 25 carrying eccentric pins located in bores in links 40 the other forward ends of which receive pins on the crosshead : a raised portion of each face 38 acts as a stop to prevent excessive turning of the blade. The distance between the centres of these bores is substantially that of the eccentricity of the crank pins on the blade roots and the length of the crosshead is substantially within the area defined by the crankpin during a complete rotation. The pivotal connection on the crosshead for each link is offset from the propeller axis by a distance equal to the eccentricity of the crank pin on the blade root with the result that as the crank pins move from one side to the other of the plane of the axes of the propeller blades, the longitudinal centre lines of the links 40 remain substantially parallel to the propeller axis. The forward position of the crosshead corresponds to the full astern setting of the blades and vice versa. In assembling the hub the crosshead is passed through a radial bore 16 and bolted to the control rod and the blade root 21, held in its bearing housing 18 by the crank disc 25 which with the base of the blade-root engages a lip 22 on the housing, is thereafter bolted on the hub. In a modification, the bearing housing is omitted and the crosshead is inserted into the hub from the rear, the rear wall being made removable. The links 40 may be replaced by an arcuate groove 66, Fig. 9, in the crosshead, in which a block 65 carrying the crank pin 63, slides, the groove being centred about a point 69 displaced from the propeller axis by an amount equal to the eccentricity of the crank pin.

Title: 1,2,3,4-tetrahydro-í¸1,2-cyclopenteno-[4,5:2,3]-naphthalene derivatives and process for their manufacture
IPC: C07D319/08
Filed: 1961-10-11
Abstract: The invention comprises compounds of the formula <FORM:0983868/C2/1> in which R represents an alkyl radical, R1 represents a hydrogen atom or a hydroxyl, alkoxy or acyloxy group and R2 represents a hydrogen atom or a methyl group.  The novel compounds may be made by reacting a salt of a tertiary amine with a compound of the general formula <FORM:0983868/C2/2> in which R, R1 and R2 have the above meanings. The acid component of the amine salts may be a weak acid, such as acetic or propionic.  Instead of the salts the amine and acid may be added separately.  Inert organic solvents may be used. Examples of suitable salts are the acetate or propionates of triethylamine, dimethylaniline, methyldiphenylamine, methylpiperidine, endoethylene piperidine or endoethylene-piperazine. The reaction may be effected at elevated temperature, for example, under reflux.  The product is worked up by extracting the organic phase with water, drying it, distilling under reduced pressure and purifying by chromatography on silica gel.  The dialdehyde starting materials are made by the following steps:- <FORM:0983868/C2/3> Compound Ia is made by Diels-Alder reaction of juglone acylate and acyloxybutadiene.  By reacting I or Ia with a Grignard reagent, e.g. methyl magnesium iodide, an alkyl group is introduced (and the acyl group removed in the case of Ia) to form II or IIa respectively.  Compound II or IIa is hydrolysed to yield III or IIIa which is reacted with a ketone, such as acetone, to form IV or IVa.  IVb is made by reacting IVa with acetic anhydride.  IV, IVa, or IVb is oxidized with osmium tetroxide to diol V, Va or Vb, which is converted to dialdehyde VI, VIa or VIb with lead tetra-acetate. Detailed examples are given.

Title: Improvements in and relating to the control of low pressure gaseous electric discharge devices
IPC: H02M7/06
Filed: 1932-12-28
Abstract: 393,880. Converting. AKT. - GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Dec. 28, 1932, No. 36706. Convention date, Dec. 28, 1931. [Class 38 (ii).] Relates to an arrangement for supplying starting potentials to the anodes of a gaseous discharge device having grids to which may be applied a negative bias for raising the ignition potential above the normal operating potential. The starting potentials are supplied from a condenser which is momentarily connected to the anodes in succession by means of a rotary switch, and is recharged to the required potential in the intervals. The switch has a stator m on which are mounted segments p, q and a rotor n carrying a brush driven by a synchronous motor. The condenser h charges during engagement of the brush with a segment p and discharges to an anode b during engagement of the brush with a segment q, thus causing the arc to start. The stator m can be angularly adjusted in order to vary the moment of ignition. The rotary switch may be mounted in a chamber which is either evacuated or is filled with gas under pressure. When an evacuated chamber is used it mav be connected to the vacuum pump used for maintaining the vacuum in the main discharge vessel. In a modification the D.C. generator i is replaced by an auxiliary rectifier. In a further modification the segments p are connected to the starconnected secondary of an auxiliary trans. former.
