Abstract: 417,128. Turning-gear. CIRRUS-HERMES ENGINEERING CO., Ltd., and CAPLE, A. H., 274, Gresham House, Old Broad Street, London. March 28, 1933, No. 9285. [Class 7 (v).] An inertia starter is of the type comprising a high-speed flywheel 2 located within the housing of a double epicyclic gear train through which the flywheel drives a starter claw 5 movable at will into engagement with a counterpart claw 6 on the engine crankshaft. The gear train includes a relatively fixed internally toothed ring 9 meshing with the planet pinion 8 and mounted by means of a slip clutch element between the separable sections 1, 1<a> of the housing to enable the toothed ring and the slip clutch element to be exposed for inspection. As shown, a ring 19 of friction material, such as bonded asbestos, is interposed between the toothed ring 9 and a metal ring 21 held against rotation by a dowel pin 23 and exposed to the pressure of springs 20 in pockets 22. The planet pinion 8 is driven by a sun pinion 7 on the spindle 3 of the flywheel and is integral with a planet pinion 10 driving an internal gear 11, to the hub of which the starter claw 5 is splined at 29. The flywheel is driven by an electric motor, the armature 27 of which is mounted on the flywheel spindle 3, and the starter claw 5 is moved into engagement with the claw 6 by an axial rod 30, springs 32, 36 being interposed between the claw member 5 and abutments 33, 37 on the rod. A metal disc 34 on the rod co-operates with contacts 35 in the circuit of the motor 25 to switch on the motor on movement of the rod 30 to the right in the Figure and to switch off the motor when the clutch 5, 6 is engaged.

Title: Improved method relating to the quenching of hot coke and the like
IPC: C10B39/04
Filed: 1920-03-31
Abstract: 153,838. Dempster, R. & J., and Beard, G. F. H. March 31, 1920. Cooling discharged materials.-Coke is quenched by placing it in close proximity to or in direct contact with a thin film or quantity of quenching liquid separated from the main bulk. In one construction the coke-supporting plates b of an endless conveyer work just below the level of the liquid in tank a. The floor of the tank at one end and the conveyer may be inclined, as shown, so that any breeze which falls between the plates of the conveyer will be swept out of the tank. The conveyer plates may be of V-shape, and their forward edges may be bent downwards to promote circulation of the water. In the form of conveyer shown in Fig. 5, the coke is supported on the projections b<5> above the level of the water, so that the cooling is effected wholly by steam. The water-level in the tank may be varied by plungers or by inflatable bags of flexible material, or the conveyer may be raised and lowered by mounting the supporting-rollers on eccentrics or verticallymovable slides. When a conveyer is not used, the surface of the quenching-liquid may be agitated by paddles.
Patent GB-1094992-A (GB)
Title: Separating and recovering cyclopentadiene
Inventor: WEITZ HANS-MARTIN
IPC: C07C7/11
Filed: 1965-03-05
Abstract: <PICT:1094992/C4-C5/1> Cyclopentadiene is recovered from C5 hydrocarbon containing diolefins, prior to the separation of isoprene, by counter-current contact with sufficient selective solvent to dissolve substantially only the cyclopentadiene, the solvent being a heterocyclic compound having a nitrogen or oxygen heteroatom adjacent to a single carbonyl group, contacting the resultant solution with an inert liquid or gas to remove dissolved diolefins other than cyclopentadiene and expelling cyclopentadiene from the remaining solution; recovered solvent may be recycled preferably after removing cyclopentadiene dimer from a bleed stream. The solvent may be a lactam, lactone, N-alkyllactam, N-hydroxyalkyllactam, N-acylpyrrolidine or N-acylpiperidine, and may contain up to 40% of water; preferably the same solvent is used in the subsequent isoprene recovery.  In a preferred embodiment the mixture as a gas enters tower 1 by line 4 and the solvent by line 5. The solution is passed to tower 2 where it is contacted with an inert gas, e.g. cyclopentadiene, hydrocarbons less soluble than diolefins, nitrogen or steam; in an example C5 gas from the process after removal of isoprene enters by line 8 and steam by line 9.  In the absence of steam, heat may also be applied.  The gases obtained are returned to tower 1 by line 4.  From the bottom solution then enters tower 3 where it is heated to expel cyclopentadiene recovered as a side stream 10.  Overhead gases may be returned to tower 2 as all or part of the stripping gas.  The gas-liquid absorption step may be replaced by liquid-liquid absorption using a counter-solvent (hydrocarbons) or anti-solvent (water) introduced near the point of removal of solution, or by an extractive distillation.

Title: An improved manufacture of tertiary isomers of olefins
IPC: C07C37/14
Filed: 1945-04-18
Abstract: Isomers of tertiary olefins are prepared by alkylating a phenol with the tertiary olefin, dealkylating the product to obtain a mixture of the isomers of the tertiary olefine, separating the desired isomer or isomers, and re-alkylating a phenol with the remainder.  A C5 mixture of saturated and unsaturated hydrocarbons may be passed counter-current to a phenol such as cresols or xylenols at 0-100 DEG C. and atmospheric or higher pressure, in presence of a condensation catalyst, e.g. sulphuric acid or its esters, aromatic sulphonic acids, zinc, aluminium or tin chlorides and boron fluorides.  The alkylate is stripped of unreacted hydrocarbons and heated in a regenerator-fractionator, for example at 190-210 DEG  C., in the presence of the same catalysts, tertiary olefins distilling overhead and being further fractionated to yield 2-methylbutene-1 as overhead and 2-methylbutene-2 as bottoms.  Either may be recycled to the alkylator to give on regeneration a similar equilibrium mixture of isomers.  Isomers of higher olefins, e.g. 2,3-dimethylbutene-1 and -2, may be isolated similarly.  In examples, mixed cresols or phenol are used for the treatment of mixed C5 hydrocarbons, pentenes or pure trimethylethylene, p-toluene or phenol sulphonic acid being the catalyst.

Filed: 1969-02-24
Abstract: 1,217,986. Measuring mass of fluid. BENDIX CORP. 24 Feb., 1969 [21 Feb., 1968], No. 9772/69. Heading G4H. To measure the amount of fluid in an enclosed metallic cavity, the cavity is excited by electromagnetic energy at a swept frequency extending between f 1  and f 2 , the number N of resonant modes in the cavity, where N is proportional to KE<SP>3</SP>/ 2  (f<SP>3</SP> 2 -f<SP>3</SP> 1 ), being counted. Since E, the average dielectric constant of the contents of the cavity is representative of the mass of liquid the number N is proportional to the amount of fluid. The apparatus may also be used to determine the changing volume of, for example, a metalized bladder containing a fluid, the bladder being in a metallic cavity. In the embodiment described, either one probe acting as both an excitation probe and a detector probe (Fig. 5, not shown) is used or a first probe 8 (Fig. 1) receives the swept frequency signal from a voltage controlled oscillator 19, a second probe 10, detecting the electromagnetic field intensity, being connected to a crystal detector 24, the output from which after amplification is fed to a peak detector 28, the output pulses from which are counted in a counter 16. The count is fed to a processor 18 calibrated to give its output as a function of the fluid mass.
