Patent GB-156089-A (GB)
Abstract: 156,089. Maschinenfabrik Oerlikon. Dec. 30, 1919, [Convention date]. Master control systems.-Motor controllers for electrically propelled vehicles are operated by auxiliary power in accordance with the setting of a master controller, and are provided with mechanical indicating means to ensure coincidence in the follcw-up action. The Figure represents diagrammatically a motor controller 9 coupled to an operating shaft 10. According to the arrangement shown in Fig. 1, the shaft is geared to an auxiliary electric motor 13 connected to a reversing switch 15 and two normally open switches 1, 3 associated with a master handle 29. When the handle is turned one step in either direction, the corresponding switch, either 1 or 3, is closed, the motor is started in the corresponding direction, and the controller 9 is operated accordingly. A mechanical drive from the motor 13 actuates a member coaxial with the master handle in such a manner than when it has overtaken the handle the switch 1 or 3 is opened and the motor 13 is deprived of current. Successive steps of the handle thus produce successive similar operations of the controller 9. The shaft 10 is provided with mechanical indicating means. The arrangement shown in Fig. 2, instead of an electric motor, comprises a pair of pneumatic cylinders 18, 19 controlled by valve-magnets connected to switches 1, 3 associated with the master handle 29. The action of the handle and the order of operations are the same as in the electric motor arrangement.

Abstract: 781,023. One-way clutches. BORG-WARNER CORPORATION. June 1, 1955 [June 21, 1954], No. 15704/55. Class 80 (2). Cylindrical inner and outer races 10, 11 of a one-way engaging device, such as a clutch, of the kind having tilting sprags 23 biased into wedging relation with the races by a unitary spring 22, are maintained concentric by a number of discrete circumferentially spaced plain or roller bearings 35 circumferentially aligned with the sprags and engaging the races. The one-way clutch in Fig. 1 comprises tilting sprags 23 maintained in " fully-phased " relation, as described in Specification 763,353, by engagement in apertures in rigid inner and outer cages 21, 19 and in an interposed spring-strip sprag-energizing cage 22, as described in Specification 713,308. The bearings are plain bronze slipper-blocks 35 having inner and outer bearing surfaces curved to conform to the races. Either the inner or outer face of each block may have two ledges 45 fitting between the adjacent race and cage, and the opposite face may have one such ledge. Openings 42 in any one cage, e.g. 21, receive the bearing blocks 35 with little clearance whilst openings 27, 39 in the remaining cages are wide to permit sprag movement without these races contacting the bearing-blocks. In Fig. 5, not shown, the spring-strip cage 22 is replaced by a continuous spring passing through inclined openings in the sprags and straight openings in the bearing- blocks. In Fig. 6, not shown, the bearing-blocks are each formed with a lip which is bent over the outer surface of the inner cage 21 to retain the parts assembled. In Figs. 10-12, not shown, the bearings are rollers retained in either the inner or outer cage by transverse walls. In Figs. 13 and 14, not shown, rollers are retained in apertures in the spring strip cage 22 by projections on the latter engaging depressions in the ends of the rollers.

Abstract: 1358997 Blast furnace operation P RHEINLANDER 20 May 1971 [23 May 1970 26 June 1970] 15966/71 Heading C7D A supplementary carbonaceous fuel is decomposed externally of the furnace (which operates with hot blast) and the products introduced into the furnace hearth, the resultant cooling effect being compensated temporarily by using less ore in the charge, or by increasing the oxygen content or temperature of the bath, until a new equilibrium is attained. The fuel may be reacted with sufficient oxygen to convert all its carbon content to carbon monoxide, or with less oxygen when soot is produced; in such a case the oxidizing gas should be pre-heated so that a crystalline reactive soot is obtained. In another embodiment water vapour is added to the fuel during the reaction. Decomposition products of the fuel may be supplied to the hearth through a pipe extending through a tuyÞre, or separately from the latter. Decomposition may be carried out in a common reaction chamber serving all tuyÞres, or each tuyere may have an individual chamber. The furnace may be operated under such conditions that the CO 2 : CO and H 2 O: H 2  ratios in the top gas are those corresponding to the equilibrium between iron, wastite and carbon, while some or all of the top gas may, after removal of CO 2  and H 2 O be recycled to the reaction vessel.

Abstract: 977,536. Semi-conductor limiting circuits. RADIO CORPORATION OF AMERICA. May 3, 1961 [May 20, 1960], No. 16103/61. Heading H3T. A circuit for limiting a sinusoidal input current to produce a rectangular wave output comprises a bridge circuit one arm of which is constituted by one or more " backward " diodes 26, the remaining arms of the bridge being constituted by resistors R 1 , R 2 , R 4  whose values are so chosen that the bridge is substantially balanced when the diode or diodes is or are in the low-resistance condition. The " backward " diode, otherwise called a " tunnel rectifier," is a heavily-doped junction diode so constructed that it has a very low back resistance and for voltages in excess of a fraction of a volt a very low forward resistance, the two values of resistance being substantially the same but the resistance over the intervening voltage region being very high. Hence on the application of a sinusoidal current from a highresistance source 24 the voltage appearing between output terminals 28 and 30 switches rapidly and alternately between two values #v and #v<SP>1</SP> as illustrated in the diagram of Fig. 2 in which line 34 represents the ohmic resistance which inserted in place of the diode would balance the bridge. The two voltage values #v, #v<SP>1</SP> are thus substantially independent of input current amplitude. The amplitude of the output rectangular wave may be increased by connecting two or more backward diodes in series, anode to cathode, Fig. 3 (not shown). A symmetrical output may be obtained by the use of two backward diodes connected back-toback, Fig. 5 (not shown). A capacitor may be connected in parallel with resistor R 4  to compensate for the capacitance of the diode and hence increase the switching speed of the circuit. The value of the capacitor may be selected to provide over- or under-compensation.

[Also in Group XXXIV] In an hydraulic brake arrangement for motor vehicles, more particularly heavy duty vehicles such as mobile cranes, there is an hydraulic running brake effective on all road wheels and a hydraulically operated holding brake effective on only some of the road wheels. As illustrated, the vehicle is equipped with a normal four-wheel hydraulic braking system (i.e. the running brake) operated by a pedal 5 through a master cylinder 4 and pipe line 3 to the braking cylinders 1 and 2 of the front and rear wheels of the vehicle respectively. A hand brake lever 6 is coupled with a hydraulic control plunger 7 and connected through a pipe line 8 with an actuating plunger 9 which applies the rear wheel brakes by means of the brake lever 10 through the rod 11. The rod 11 is provided with ratchet teeth 12 and a pawl 13 co-operates with the latter to keep the holding brake engaged. The pawl 13 may be disengaged by depressing the pedal 18 which operates through a control plunger 17 and pipe 16 to actuate a disengaging plunger 15 to allow the holding brake to be disengaged. Another arrangement is shown to enable the holding brake to be disengaged by depressing the brake pedal 5. The pedal 18, control plunger 17 and pipe 16, in this case, are replaced simply by a pipe 20 (illustrated with a chain-dotted line) connected to the pipe line 3 of the hydraulic running brake.

Title: Process for the dealkylation of aromatic compounds
Inventor: VISSER PIETER
IPC: C07C4/08
Filed: 1960-05-09
Abstract: Alkyl aromatic hydrocarbons are dealkylated in the presence of hydrogen at elevated temperature by contact with a molten salt or a mixture of molten salts.  Suitable conditions are 700-1200 DEG C., 0.01-0.1 sec., 1-40 atm. abs. and a hydrogen to hydrocarbon mol ratio of 1-20.  The reactants may be passed through the molten salt(s) but preferably the salt is entrained in the feed.  In the drawing, hydrocarbons and hydrogen enter by lines 9 and 11 and entrain molten salt at 4.  The salt is separated at the top of reactor 1 and passes by liquid seal 8 into the regenerator 2, surrounding the reactor, where the salt is regenerated <PICT:0911321/IV (b)/1> and heated by oxygen, with added fuel or flue gas if necessary, from line 14.  The product is quenched, e.g. with steam from inlets 20.  If desired, hydrogen may be supplied by cracking a hydrocarbon yielding hydrogen by contact with the salt before introducing the hydrocarbon to be dealkylated.  Suitable salts are hardening salts used in metallurgy, alkali metal, particularly potassium, sulphates or chlorides or their double salts or other metal chlorides, sulphides or cyanides.  When using mixtures, these preferably corresponding to the eutectic point. Specification 859,079 is referred to.
