Title: Method of and apparatus for quenching coke
IPC: C10B39/04
Filed: 1974-04-01
Abstract: 1458313 Quenching hot coke ESCHWEILER BERGSWERKS-VEREIN 1 April 1974 [19 April 1973] 14336/74 Headings F4B and F4X In quenching hot coke, both water and steam (which is generated by the quenching) pass downwardly through the coke, the coke being shielded against external air and supported on a substantially horizontal permeable surface with a constant height of coke over the surface. The water and steam flow for 45-90 seconds uniformly through the coke until the steam temperature has cooled at least to 400 C., the amount of water used being metered such that it all evaporates except for a part which is absorbed by the coke leaving a moisture content in the quenched coke below 2% by weight of the quenched coke. As shown in Fig. 2, the coke is quenched in a container 1 having grate bars 17 at its bottom. The quenching water is supplied through pipes 37 and 33, a hollow lid 6 and pipes 31 in the lid. The steam pressure opens hinged side walls 21 of a base box 15. The box 15 includes the grate bars 17 and is hinged to the bottom of the container 1 at 16 to enable discharge of the container. The container has a water-cooled top part 22. The lid 6 can be raised and lowered by an hydraulically operated cylinder 36. The lid includes locking anchors 25, which are hydraulically actuated at 27, and a hose 29 in which water pressure can be increased to make a seal. The container 1 with its base box 15 is carried on a low-loader 38, Figs. 3 and 4, but the lid 6 remains at a quenching tower (not shown). For loading the container with hot coke, the low loader is aligned with a coking oven 39 and a coke guide 40 on a wagon 41. The guide 40 is clamped to the oven by an hydraulic device 47. The container 1 is pressed into engagement with a sealing surface 49 of the coke guide by hydraulic operating cylinders 50 on the low loader. The coke guide 40 is connected through a coupling 57 with a rotor washer 55 on the low loader for cleaning air which passes from the guide 40 to the atmosphere. The coke cake from the oven passes over a saddle member 64 which breaks up the cake and directs the coke towards the opposite corners of the quenching container. When the container has been filled it is disengaged from the coke guide. The container is then moved by the low loader to a quenching tower (not shown) and, after quenching, moved to a ramp (not shown) where it is emptied.

Title: Organosilants
IPC: C07F7/12
Filed: 1956-05-09
Abstract: Silanes containing silicon-bonded alkyl groups are prepared by reacting compounds of the formula <FORM:0831422/IV (a)/1> with a complex of an alkyl magnesium chloride, bromide or iodide and a compound Q (later defined); wherein in the above formula R1, R11 and R111 are hydrogen, or alkyl, cycloalkyl or aralkyl radicals which may be substituted by non-reactive substituents, b, c and d are 0 or 1, and X is halogen or an alkoxy or aryloxy group.  The compound Q is a substituted or unsubstituted heterocyclic ether having 5 or 6 atoms in the ring of which one is oxygen and the remainder carbon except that a substituted nitrogen atom may replace the 4-carbon atom when the ring has 6 atoms, the ring containing not more than one double bond and at least one carbon atom in the ring adjacent the oxygen being free of substituents, and there being no substituent on the ring which reacts with any compound or product of the reaction mixture.  Examples of such ethers are tetrahydrofuran, tetrahydropyran, 2 - methyl tetrahydrofuran, 2 - ethoxytetrahydropyran, tetrahydrofurfuryl ethyl ether, dihydropyran and N - methyl morpholine.  Reaction of the silicon compounds is effected in an inert hydrocarbon solvent, and after completion, separation is effected by hydrolysis to obtain the magnesium halide in aqueous phase and the alkylsilane in the hydrocarbon phase.  The alkyl groups may contain up to 30 carbon atoms and the products include mono-, di- and more highly alkylated silanes.  A multiple use may be made of the process to introduce more alkyl groups.  The examples describe the preparation of (1) tetradodecylsilane, together with tridodecylsilanol, hexadodecyldisiloxane and other by-products; (2) dodecyl trichlorosilane and bis - dodecyldichlorosilane; (3) octadecyltrichlorosilane; (4) tetradodecylsilane; (5) dimethyldioctadecylsilane; (6) dimethyldidodecylsilane; (7) dioctadecyldiethylsilane; (8) didodecyldiethylsilane; (9) diethyldichlorosilane; (10) decylethyldiethoxysilane; (11) octadecyldiethylphenoxysilane; (12) dodecyltriethoxysilane; (13) tributylsilane; (14) dibutylchlorosilane.

Patent GB-1109192-A (GB)
Title: A diaphragm-stop preselector for a photographic camera
IPC: G03B7/16
Filed: 1966-04-01
Abstract: 1,109,192. Diaphragm setting means. M.C. SCHNEIDER and H.J. SCHNEIDER [trading as JOS. SCHNEIDER & CO. OPTISCHE WERKEJ. April 1, 1966 [April 3, 1965], No. 14436/66. Heading G2A. A diaphragm-stop pre-selector is jointly controlled by two independent selectors each having a plurality of positions representing different values of respective variables (e.g. film sensitivity, distance or focusing range), the setting means associated with these selectors having respectively different degrees of freedom. The range selector is a ring (9) on the housing (1) of the camera Fig. 1 (not shown) carrying a scale (9a) reading against a fixed mark on the camera. Rotation of this ring (9) is transmitted, via threaded rings (8, 7 and 16) into axial movement of the objective lens (31) for focusing purposes. A spring-loaded rod 4 slides axially in a bore (1a) in the housing, and its forward end bears against the face of a ring 5, said face being formed as a cam surface. A lug 12 fixed to the ring (9) engages in a cut-out 5b on ring 5, so that ring 5 rotates with the first ring (9), and thus rod 4 moves axially with the cam surface on ring 5 in accordance with the distance setting. Also mounted on the camera housing is a sensitivity-selector ring (10), actuated by a knob (11), and reading against a film-sensitivity scale. Ring 10 has a diagonal cam-slot 10a which receives a stud 5a projecting from ring 5. Thus rotation of ring 10 results in an axial movement of ring 5, and hence of rod 4. Thus ring 5 receives a rotational movement from the first ring (9) (distance setting) and an axial movement from ring 10 (film-speed setting), both of these affecting the axial position of rod 4. The diaphragmsetting mechanism includes a rotatable ring 15, having an extension 15b with a stepped profile 15c. The diaphragm is normally maintained in a fullyopen position, and closed to the selected position only when the shutter release is pressed. This selected position is determined by the position of rod 4, which will arrest the movement of ring 15 according to which part of the stepped profile 15c it is in alignment with. The ring 15 may, if desired, be de-coupled and adjusted manually.

Title: Improvements in and relating to wave length and like indicators for use in wireless telegraphy and wireless telephony
IPC: G01R23/00
Filed: 1922-05-23
Abstract: 199,233. Rees, H. P. May 23, 1922. Condensers.-In a wireless receiving set provided with a tuning condenser 4 having a pointer 6 moving over a circular or arc-shaped scale 7 graduated in wave-lengths units or the equivalent, the scale 7 is adjustable, in order that true readings may be obtained when the set is used with aerials having slightly different constants. In the form shown, the scale is mounted in spring clips 9, 10, and is held in its adjusted position by a clamping-screw 15. The scale may have a separate set of graduations in wave lengths for each position of the switch 3 varying the inductance 2, but it is preferably provided with a single set of graduations in arbitrary units and used in conjunction with a calibration card. The set is prepared for use by first tuning it to signals of a known wave length, and then adjusting the scale so that the correct graduation, as indicated by the card, is opposite the pointer 6. If the scale is clamped in this position, the card will give the true wave lengths for all positions of the switch 3 and pointer 6, so long as the aerial and other connections remain unchanged.

Abstract: 1,092,690. Error detection arrangement. RICOH KABUSHIKI KAISHA. April 1, 1966, No. 14511/66. Headings G4A and G4H. A circuit for converting coded data to another code includes means for checking the veracity of an output signal whereby the output signal is fed back into the circuit to produce a fault signal if the information as presented by the output signal does not agree completely with the information as presented by the input signal. As shown, digital data is presented in parallel to inputs AI1-AI3, connected to AND gates formed by diodes d1, d2. The input bits are inserted once by transistors TS and again by transistors TM so that the member and its inverse can be presented to inputs A1M-A3M, A1S-A3S of a diode matrix arranged to give a pulse on one out of eight lines D0-D7 shown. The lines are coupled to lines E0-E7 of a second diode matrix arranged to produce the second coded signal, the output signal appearing at terminals BO1-BO3. This signal is immediately applied to inputs BI1-BI3 to produce a signal and its inverse applied at inputs B1M-B3M, BIS-B3S of the second matrix. The signal causes a pulse on one out of the eight lines. If this matches that produced by the first matrix then no error is detected. If it produces a pulse on a different line then an error signal is produced since the matrix used is arranged such that a zero signal takes precedence and if the two pulses are in different lines a reading of " 0 " on each line is obtained.
