Title: Improvements in draw and buffer gear for railway and like vehicles
IPC: B61G9/06
Filed: 1931-07-24
Abstract: 377,429. Combined buffing and draw gear for railway &c. vehicles. MITCHELL, J., 69, Kenilworth Court, Putney, and COSSEY, J. C. G., Calbourne, The Vale, Golders Green, both in London. July 24, 1931, No. 21231. [Class 103 (v).] In railway and like draw and buffer gear for centre couplings of the kind in which the coupling allows relative inclination between coupled vehicles but is maintained normally at right-angles to the headstock by the buffing and draw springs and in which the draw-bar passes through sockets secured on each side of the headstock, casings are secured on either side of the headstock while further casings are slidably mounted in the fixed casings with springs interposed to absorb the heavy draw and buffing shocks whilst springs in the slidable casings absorb the lighter shocks and serve to centre the coupler after the vehicle has negotiated a curve. The casings a, b are secured to the headstock x and contain slidable casings j, k with rubber &c. springs c, d interposed. Springs n, o are arranged in the slidable casings j, k and a draw-bar r is arranged as shown passing through a ferrule s permitting angular movement. Initial compression is given to the springs n, o by the draw-bar rand nuts u, v and to the springs c, d by plates l, m. The coupler head p is supported on the springs by lips p<1>, j<1>, k<1> which permit difference of height of coupled vehicles and vertical up-and-down movement during travel.

Title: Process for the manufacture of products of the thiosemicarbazone series
Filed: 1949-08-15
Abstract: Thiosemicarbazone derivatives are manufactured by reacting a thiosemicarbazone, obtained from thiosemicarbazide and a benzaldehyde containing a carboxyl group attached to the nucleus directly, or indirectly through a saturated or unsaturated aliphatic carbon chain, with an alkanolamine, or by reacting a salt (e.g. an alkaline-earth metal salt) of such a thiosemicarbazone with a salt (e.g. sulphate, carbonate or oxalate) of an alkanolamine, or by reacting thiosemicarbazide with an alkanolamine salt of a benzaldehyde carboxylic acid of the said kind.  In examples: (1) benzaldehyde - thiosemicarbazone - 4 - carboxylic acid, 4-acetic acid or 4-acrylic acid is dissolved in water while adding diethanolamine, and the salt is isolated by concentrating the solution and adding alcohol; (2) the calcium salt of benzaldehyde - thiosemicarbazone - 3 - carboxylic acid is reacted with the neutral sulphate of diethanolamine in aqueous solution, the precipitated calcium sulphate is filtered off and the filtrate evaporated to dryness.  Other alkanolamines specified are mono- and triethanolamine.  The Specification as open to inspection under Sect. 91 comprises also a reference to the use of benzaldehyde - thiosemicarbazone - 4 - propionic acid, glucamine and methylglucamine as starting materials.  This subject-matter does not appear in the Specification as accepted.

Title: Improved automatic gearbox control device
IPC: F16H63/02
Filed: 1962-06-01
Abstract: 972,024. Change-speed control. COMPAGNIE DE CHEMINS DE FER DEPARTEMENTAUX. June 1, 1962 [June 5, 1961], No. 21325/62. Heading F2D. An automatic mechanical, pneumatic, hydraulic or, as shown, electrical control for a road or rail vehicle comprises an output speed responsive generator 7 which energizes relays at predetermined speeds to effect ratio shift. The predetermined speeds at which ratio shifts occur may be modified by a variable resistor 12 responsive to accelerator pedal position and by a switch 15 which is closed above a predetermined engine speed. As shown for three change speed gears in series which provide n Î p Î q ratios, the control circuit has three sets of relays A 1  . . . A n-1 ; B 1  . . . B p-1 ; C 1  . . . C q-1 , each of which effect ratio shifts in the corresponding gear. When the vehicle is at rest and all the relays are de-energized each gear provides its lowest ratio. As the vehicle speed increases to a first predetermined value the relay A 1  is energized to effect a ratio shift in the first gear. On further increases of vehicle speed the relays A 2  . . . A n-1  are successively energized producing corresponding ratio shifts in the first gear. When the relay A n-1  is energized an increase of vehicle speed to the next predetermined value energizes the relay B 1  which effects a ratio shift in the second gear and trips a switch KB 1  thereby inserting a resistor RB 1  in the supply circuit to the set of relays A 1 . . . A n-1  and de-energize the latter whereupon the first gear returns to its lowest ratio. The switch. KB 1  also introduces a compensating resistor R<SP>1</SP>B 1  into the circuit which maintains the overall resistance of the circuit constant. As the vehicle speed continues to increase the relays A 1  . . . A n-1  are again successively energized, producing corresponding ratio shifts in the first gear until the relay B 2  is energized and trips switch KB 2  which inserts a further resistor in the circuit of relays A 1  . . . A n-1  which are again de-energized. This process is repeated until both the relays A n-1 , B p-1  are energized whereafter the relay C 1  is energized to effect a ratio shift in the third gear and trip switch KC 1  which inserts resistor RC 1  and thus de-energizes relays A 1  . . . A n-1 , B 1  . . . B p-1 . The process then repeats until the highest ratio is engaged with relays A n-+1  B p-1  and C q-1  all energized. The predetermined speeds at which up-shifts are effected are reduced slightly when the input shaft speed exceeds a predetermined speed by closing a governor controlled switch 15 which bridges a resistor 14. The slider 13 of a potentiometer 12 is connected to the carburetter butterfly valve or engine fuel rack and may reduce or increase the speeds at which up-shift occurs.

B n-1 ), correspondingly-numbered devices (A m , B k  where m = k) having the same rate of rotation of polarization plane with respect to electric current, each successive device of a group being twice as sensitive to current as the next preceding device; each device being located between a first polarizer 1 and a second polarizer (a m  or b k ) having polarization planes differing by an angle (# m  or # k ) such that  and and  A method of obtaining a binary measurement of current comprises: supplying light of a common intensity to first polarizers defined above, and determining whether the light emerging from a second polarizer lies in predetermined relationship with set limits as follows: and "b" polarizer, or the "an" polarizer: above or below half the maximum intensity; any "a" polarizer other than "a n ": above an upper threshold, or below a lower threshold, or in the range between the upper and lower thresholds, which lie on either side of half the maximum intensity. If the light from any polarizer a 1  ... a n  falls above or below the limits defined above, then a value of 1 or 0 is unambiguously assigned to the corresponding digit. If the light from any polarizer "a i " falls in the range between the upper and lower thresholds, then determination of the ith digit is made by further inspection of the "b i " polarizer and of the (i+1)th digit as follows: if "b i " output above half with (i+1)th digit = 0 or if "b i " output below half with (i+1)th digit=1: then the ith digit is assigned 1; but if these combinations are interchanged, then the ith digit is assigned 0. Faraday-shift devices which may be of paramagnetic flint glass or premagnetized ferrimagnetic garnet crystal are arranged in pairs A 1 B 1  &c., each succeeding pair being surrounded by twice as many turns of wire as the next preceding pair, the single device A n  having twice as many turns as the pair A n-1 B n-1 , the windings being connected in series. Light 100, preferably infrared, illuminates the devices through a first polarizer 1, emerging, after passing through the devices A, B, from second polarizers a, b having their polarizing planes inclined to that of the first polarizer 1 by-respective angles #, # defined above. Optical waveguides 2 transmit the emergent light to detection apparatus (not shown) where the above-defined determinations may be made with elements including "exclusive-OR" gates.  Infrared light is preferred because it enables Faraday shifts of multiples of # to be obtained. The lengths of the Faraday magneto-optical bodies may be varied instead of the numbers of turns of wire.
