Abstract: 975,656. Counter pressure brakes. ROBERT BOSCH G.m.b.H. Jan. 15, 1962 [Jan. 14, 1961], No. 1406/62. Heading B7H. [Also in Divisions F1 and H3] A dynamic brake for a vehicle, comprising a flap 12 disposed in the engine exhaust, pipe, is operable only when the engine speed exceeds a predetermined value. Impulses from the ignition system, which comprises contact breaker 21 and ignition coil 15 are passed through the primary of a transformer 26. Connected to the secondary is a diode 34 in series with the parallel combination of resistor 39 and capacitor 40, across which is produced a D.C. potential proportional to engine speed. The arrangement also comprises a pair of cross-coupled transistors 33, 34, the forward coupling path comprising resistor 43 and the back-coupling path potentiometer 45, 46 and resistor 37; the base of transistor 33 is connected to resistor 39 by way of diode 35. At low engine speeds the voltage across resistor 39 is low, the transistor 33 conductive and transistor 44 non-conductive so that closure of the brake control switch 48 will not result in energization of the solenoid 13. When, however, the engine speed exceeds a predetermined value, the voltage across resistor 39 is sufficiently positive to bias transistor 33 non-conductive, whereupon transistor 44 becomes conductive, and if switch 48 is then closed energization of solenoid 13 ensues to operate the flap 12. Capacitor 50 removes any residual ripple from the voltage at the base of transistor 33, while a diode 49 prevents induced voltage peaks from the solenoid 13 reaching the transistor 44. The arrangement may also be used to block the supply of fuel to the engine.

An invertible plough, of the type having a supporting frame 10 on which a tool-carrying frame 11 is rotatable about a longitudinal axis, is provided with a tail-wheel 31 mounted on an arm 29 pivoted to the tool-frame so as to be swingable under gravity between limit-positions during change-over, means being provided for preventing the wheel from swinging violently about during the change-over. The frame 11 carries the duplicate plough-bodies 15, 16 mounted upon brackets 27 to the rearmost of which the arm 29 is pivoted at 28. Working depth is adjusted by threaded stops 23 on the fixed rear portion 18 of the supporting frame 10. These stops engage a plate 32 secured to the arm 29. The frame 10 also carries a depending bracket 25 having a rearwardly-extending pin 26 at its lower end: during change-over, a fork 35 attached to the arm 29 engages the pin and locates the wheel 31 and arm 29 until the completion of the reversal, thus obviating undesirable impacts between the arm 29 and the limit-stops.

Title: Improvements in and relating to the conversion of saturated hydrocarbons, in gas or vapour form, especially methane, into unsaturated hydrocarbons
IPC: C07C2/78
Filed: 1927-01-19
Abstract: 264,845. I. G. Farbenindustric Akt.- Ges. Jan. 20, 1926, [Convention date]. Hydrocarbons; benzene; acetaldehyde. - The thermal decomposition of gaseous or vaporous saturated hydrocarbons, particularly methane, into unsaturated hydrocarbons, particularly acetylene. is effected by passing the saturated hydrocarbons, alone or diluted with nitrogen or other inert gases, through a flame which extends across substantially the whole cross-sectional area of a tube. The flame may be a disc-like flame produced by burning a combustible gas, such as a part of the gas to be treated, with air &c. in a plurality of separate burners. The reaction products may be rapidly cooled to separate the hydrocarbons, or they may be subjected directly to further chemical treatment to vield other products, such as benzene or acetaldehyde. The residual gases containing hydrogen and carbon monoxide may be converted catalytically into methane, which may be returned to the process. Suitable apparatus comprises an inlet tube E for the gas to be treated having branches m and a main branch R controlled by taps F, g. The branches m lead to burners i arranged radially in a horizontal plane, as shown in Fig. 2, and projecting into a reaction tube K; the burners have flattened nozzles and are fed with air &c. through pipes h. In use, the burners are lit by an ignition device (not shown), such as an induction sparking apparatus, and the main part of the gas to be treated flows through the tube R and then through the disc of flame produced by the burners. The reaction products preheat the gases flowing in the tube R and are withdrawn through a pipe S. The air &c. and/or the combustion gas may be preheated, preferably by exchange of heat with the reaction products. The Specification as open to inspection under Sect. 91 (3) (a) states that the thermal decomposition may be effected in a zone of high temperature obtained by the flameless combustion of part of the gas to be treated. In this connection a modified apparatus is described in which the burners i are replaced by 32 radially disposed oxygen-delivering nozzles and in which the reaction tube is fitted internally, at the level of the nozzles, with a horizontally arranged gauze of tungsten wire covering the whole cross-section of the tube and supporting a thin layer of platinized asbestos. A further modification is described also in which the platinized asbestos is replaced by a plate of highly porous refractory material, such as " Marquardt composition," mounted about 1 cm. below the nozzles. This subject-matter does not appear in the Specification as accepted.
