Title: Improvements in and relating to railway bogies
Inventor: THORNELEY NEVIN
IPC: B61F5/36
Filed: 1956-10-02
Abstract: 823,090. Railway vehicle undercarriages. METROPOLITAN - VICKERS ELECTRICAL CO. Ltd. Dec. 31, 1957 [Oct. 2,1956], No. 30007/56. Class 103(6) In a three-axle railway bogie resilient members, comprising rubber slabs 8 separated from one another by plates 10 to opposite sides of which adjacent sides of the slabs are bonded, are positioned between the upper surface 9 of a central axle box 2 and cross-stretcher members 7 which unite the downturned ends 4, 5 of equalizing beams 1, 3. Bottom plates 11 of the resilient members are housed in a recess 12 in the axle box and each top metal plate 14 has a central circular frusto-conical recess which houses a spigot 16 on the under surface of each stretcher member. With this construction movement of the ends of the equalizing beams due to tilting in the longitudinal direction of the bogie with respect to the axle boxes and also movement due to tilting of adjacent axles are accommodated by deformation of the rubber slabs. Each axle box has an upstanding flange 17 surrounding the resilient members and stretcher members 7 may carry strips 20 above the flange for protection purposes. The resilient members may be arranged at an angle to the vertical or be replaced by two rubber slabs in V- formation.

Title: Improvements relating to Electronic Organ Keying Circuits
IPC: G10H1/057
Filed: 1968-06-24
Abstract: 1,187,548. Electronic musical instruments. WURLITZER CO. 24 June, 1968 [26 June, 1967], No. 30016/68. Heading G5J. A keying circuit for an electronic organ is designed such that the note produced by depressing a pedal is sustained for a predetermined period, but is terminated rapidly should a further note be played. In Fig. 3 the circuit .below line 44 is common .to all notes played by the pedals while the circuit above corresponds only to one note, all the individual circuits being connected together at points 56 and 66. .Depression of a pedal causes the appropriate switch 46 to close, so applying a positive potential B + to the normally reverse-biased -diodes 110, 112, 124, 126 and rendering them conductive hence allowing signals to pass from the 16 foot generator 114 and the 8-foot generator 130 to the .16-foot and 8-foot outputs respectively. The outputs are sustained after release of the pedal due to the charge stored in capacitor 104 which slowly decays through resistors 98, 62 and resistors 84, 86, 96 which are associated with sustain switches 90 and 94 to provide three different rates of decay. A latching circuit 36 is provided, the transistor 70 of which is normally biased off, but is switched on when the switch 46 is closed. Hence if any of the switches 46 are closed before the capacitor 104 has fully discharged, transistor 70 will provide a virtual short circuit between terminal 68 and earth and the capacitor will discharge rapidly, so rendering the aforementioned diodes non-conductive and preventing a signal from generators 114 and 130 passing to the outputs. In order to allow the diodes to remain non- conductive when switch 46 is not closed the output from the generator should preferably be always positive, but capacitors 116 and 128 ensure that deviations into the negative region only cause diodes 112 and 126 to conduct, the diodes 110 and 124 remaining non-conductive due to the positive charge remaining on these capacitors.

Title: Improvements in bis-quaternary ammonium salts and processes for their preparation
Inventor: BARBER HARRY JAMES
Filed: 1951-12-21
Abstract: The invention comprises quaternary ammonium salts which contain the cation <FORM:0714867/IV (b)/1> They are made by reacting a compound of the type X-(CH2)4-X with one of the type Y where X is either the acid residue of a reactive ester, e.g. a halogen atom, or an ethylmethyl- or diethyl-amino group and in which, when X is the acid residue Y is diethylmethylamine and when X is ethylmethyl- or diethyl-amino Y is a reactive ethyl or methyl ester respectively. If necessary the anion of the resultant quaternary ammonium salt may be converted to the desired salt by metathesis or through the corresponding hydroxide.  Bitartrates and phosphates are obtainable by this means.  The salts are ganglionic blocking agents.  In examples: (1) 1,4-dibromobutane is treated in boiling ethanol with methyl diethylamine to yield tetramethylene - 1,4 - bis - (diethyl-methylammonium) dibromide; (2) 1,4-bis-ethylmethylamino-butane is reacted with ethyl iodide in boiling methanol to yield butane-1,4-bis-(diethylmethylammonium) iodide and in (3) 1,4-bis-diethylaminobutane is reacted in boiling methanol with methyl iodide to yield the product of (2).  In examples, details are given of the preparation of 1,4-bis-ethylaminobutane by treating N,N1-diethylsuccinamide with lithium aluminium hydride, the succinamide being made by reacting diethylsuccinate with ethylamine, of 1,4-bis-ethylmethylaminobutane by reacting 1,4-bis-ethylaminobutane with formaldehyde in formic acid and 1,4-bis-diethylaminobutane by reacting 1,4-dibromobutane with methanolic diethylamine.

Title: Apparatus for cultivating bed-mushrooms
IPC: A01G1/04
Filed: 1938-10-19
Abstract: 520,355. Cultivating mushrooms. DOBROUCHKESS, L. P. Oct. 19, 1938, No. 30257. Convention date, Dec. 8, 1937. [Class 6 (ii)] In apparatus for cultivating mushrooms, the cultivating medium and the mycelium-containing manure are arranged in separate compartments communicating with each other through small openings, different parts of the manure being kept at different temperatures. The manure is first treated to remove the cellulose layer covering the straw and the plants from the vasculose. Mycelium obtained from the germinated. spores of agaricus campestris is arranged in the manure at a temperature of 27 C. The pH of the mass is maintained at about 6À8 before and throughout its utilisation. The manure box has perforated side walls 8 carrying a series of fibro-cement shelves 7 loaded with earth 17 of pH of approx. 6À8, narrow spaces 9 communicating with the manure 16. Air penetrates through openings 11 in the floor 3 to the space 10 and escapes at the top through lantern light 5. A hollow column 12 made of porous material, but with an impervious outer surface, dips into water in the annular cup 13. Water rises by capillarity and evaporates inside the column to cool the centre of the manure 16 to approximately 5C. below the outside portions. Alternatively the inside temperature can be obtained by circulating a cold brine through suitably arranged pipes. Electric heaters (not shown) under the shelves 7 controlled by a thermostat 15 maintain the desired temperature; the ventilating fan 14 may be automatically started if this is exceeded. The earth layer is maintained by watering with about 5 per cent. of moisture, and the mycelium forms filaments which produce mushrooms 18which are collected by opening doors 6. The brackets containing the manure may be fixed in groups on frames 19 which are supported on the box's uprights by hooking on knobs 20 to facilitate easy replacement of the mycelium. In another arrangement the layers of manure and earth may be arranged horizontally if separated by a partition leaving only narrow communication openings..
