Title: Process of and apparatus for converting hydrocarbon material
IPC: B01J8/08
Filed: 1948-07-23
Abstract: In a process of converting hydrocarbons (e.g. cracking, viscosity breaking, reforming, dehydrogenating or desulphurizing) in which a bed of contact material gravitates downwardly, contact material falling on the upper surface of the bed flows through an annular metering zone to form a freely falling annular curtain and an atomizer within the curtain sprays liquid hydrocarbon into it. Conversion takes place within a reaction vessel 1 into which heavy liquid hydrocarbon under pressure is fed via a pipe 10 to an atomizer A (see Group <PICT:0658283/III/1> XXIX), within an annular curtain S of contact material C which has fallen from an inlet pipe 2 into a receptacle 3 and thence down a pipe 4 and a passage 9 between a frusto-conical pipe 5 and a core 7.  The atomized hydrocarbon penetrates almost to the outer edge of the curtain S but not through it and the curtain S is deflected on a core 12 and falls on top of a bed B of contact material, the level of which is maintained by contact material falling down pipes 15 from the receptacle 3. Vapours of lighter hydrocarbons are fed into the reaction vessel 1 via a pipe 11 and assist in vaporizing hydrocarbon in the curtain S. Spent contact material is discharged via pipes 17 and a conduit 18 and is regenerated and recirculated.  Converted hydrocarbon vapours are discharged via tubes 20 and a pipe 22.  A sealing medium, e.g. flue gases, admitted via a pipe 1a prevents exit of hydrocarbon vapours via the pipe 2 and a gaseous medium, e.g. steam, admitted below pipe 22 prevents exit of hydrocarbon vapours via the conduit 18.  The contact material may be catalytic, e.g. activated clay or silica-alumina pellets, or plural oxide compositions, silicious or non-silicious and containing, e.g. zirconia, alumina or beryllia; or it may be non-catalytic, e.g. silica or quartz.  Both liquid and vaporous hydrocarbon may be fed into the reaction vessel 1 via the atomizer A.

Abstract: 739,792. Potato &c. peelers. SOC. D'ETUDE ET D'EXPLOITATION CHIMIE ET MECANIQUE E.C.E.M. July 6, 1954 [July 8, 1953; June 14, 1954], No. 19750/54. Class 28 (2). Potatoes to be peeled are moved round against fixed and depending but yielding abrasive peeling surfaces 19 by a hand rotated abrasive bottom plate 13 fixed on a central spindle rotated by a crank handle 11 inside an abrasive perforated drum container 1-3. Holes 16 in 13 allow peelings and water to pass through to other holes 3a in the fixed bottom 3. Bent rods 22 on the rotated plate 13 assist in preventing jamming of the potatoes. Water is supplied through a guide-shaped opening in the cover, Fig. 9 (not shown). The stabbed peeling surfaces 19, Fig. 6, are mounted on pairs of wires 17 bent near their upper ends into loops 18 which yield to the push of the potatoes against and between the surfaces 19. The wires 17 are fixed in cross-bars 9 arranged swastika fashion, the ends of the cross-bars 9 being removably locked in clips 7 fixed on the inside of the container 1. The middle of the swastika comprises a square plate 10 providing a top bearing for the spindle. Instead of wires 17 flat yielding bars (Fig. 7, not shown), or flat digitated rubber bars may be used (Fig. 8, not shown). In another form (Fig. 9, not shown), the depending peelers are mounted on the cover hinged to swing up to allow charging of the container. In this case the depending peelers are mounted for handle rotation. The abrasive perforations on the fixed and moving parts are formed by stabbing but in another form, Fig. 11, a rubber plate 51 is held down by a plate 52 through the holes of which integral rubber bosses 55 project to receive stabbed abrasive domes 56 all constituting the fixed bottom of the container. Fig. 14 shows. a section of the wall of the container.

Filed: 1934-07-05
Abstract: 440,735. Ophthalmoscopes. KEELER, C. H., 47, Wigmore Street, London. July 5, 1934, No. 19829. [Class 97 (i)] The glints known as corneal and retinal reflex are reduced or eliminated by illuminating the eye of the patient by polarized light and viewing the eye through analyzing means adapted to intercept the polarized light reflected by the cornea. Light from a source 10 passes through a condenser 11 and a lens 12 which brings the light to a focus at the point 13 of the usual mirror 14 which is provided with an aperture 15. The light is plane polarized before meeting the mirror by a Nicol prism 16 so that the beam 17 illuminating the fundus 20 is also polarized. The light reflected from the fundus somewhat depolarized is passed through the aperture 15, a lens 21 and an analyzing prism 23 to the observer's eye 22 and the angular disposition of the analyzer can be adjusted relatively to that of the polarizer 16 so that it intercepts light having the original direction of polarization. A modified arrangement is described giving a positive image of the fundus to enable a photograph to be taken, a mirror and reflex prism arrangement being fitted so that the image may be viewed before the exposure is made.

Title: Improvements in or relating to tanning processes
IPC: C14C3/06
Filed: 1926-08-12
Abstract: 256,979. Mathieson Alkali Works, (Assignees of Low, F. S.). Aug. 13, 1925, [Convention date]. Chrome tanning.-Tanning baths are prepared by dissolving in water anhydrous chromous chloride or anhydrous chromic chloride under conditions such that chromous chloride is produced. Soda is added from time to time during the tanning process after the first action is complete. When chromic chloride is. employed it is necessary to add thereto chromous chloride or a substance which will produce it to render the chromic chloride soluble and this may be effected by the addition of finely ground ferrochromium or zinc. The ferrochromium may be mixed in the dry state with the chromium chloride and so put on the market or a mixture of the two may be treated with enough water to form a paste and the resulting sintered mass dried and ground. The solution obtained by the use of ferrochromium as a reducing agent consists largely of chromous chloride from which the chromic form results by oxidation which may be hastened by passing air into the solution.

Title: Improvements in or relating to machines for folding webs or strips
IPC: B65H45/103
Filed: 1930-07-02
Abstract: 355,436. Folding paper &c. UNITED AUTOGRAPHIC REGISTER CO., 2316, West 43rd Street, Chicago, U.S.A.-(Assignees of Jensen, L.; and Winters, C.; 2316, West 43rd Street, Chicago, U.S.A.) July 2, 1930, No.20117. Convention date, July 12, 1929. [Class 100 (ii).] A machine for folding strips of paper or other material transversely in zig-zag fashion comprises two or more opposed reciprocating folder-plates, which are lifted alternately or in succession, so that one plate is brought over the other or others, a reciprocating web-distributer being employed to lay the web over the plates. In the form shown :n Figs. 5 and 5a, four folder-plates 1 .. 4 are employed, two of which are normally held in a central position while the reciprocating-mechanism withdraws a third plate from the bottom of the pile, and at the same time causes the fourth plate to ride over the pile in the wake of the web-disbributer. The plates thus successively gravitate to the bottom of the pile. The web J, which may previously have been folded lengthwise, or printed upon, is laid in folds by a distributor B, in the form of a reciprocating carriage bearing rollers 11, which are vertically movable in slots, so as to have an ironing action on the paper, and to fold it over the end of the top folder-plate. The folderplate actuator comprises slide-bars 19, Fig. 5a, movable in guides and reciprocated by a lever. The folder-plates have notches in their edges, which are engaged by short lugs on the bed of the machine, whereby the two intermediate plates are held stationary. The lowest plate is withdrawn to left and right alternately and is raised by lifters F, F<1>, Fig. 5, so that it passes to the top of the pile at the following stroke. The folded strip is temporarily supported by rocking arms 30, Figs. 5 and 7, which support the strip at each side, and, when lowered, allow it to fall on to an endless conveyer, comprising parallel belts 41, which are intermittently fed by ratchet-mechanism, so as to move the folded strip laterally out of the machine. In a simpler modification, two reciprocating folderplates 58, 59, Fig. 13, are employed, and are operated by levers 60, each plate having connected to it a gripper-member 67, which is caused to grip a fold of the paper before the opposing plate is withdrawn.

[Also in Group XXXVIII] Pulse-modulated alternating currents, e.g. for selective signalling, are derived from transductors each of which has two control windings, one series connected with a resistor and the other with an inductance, so that each transductor operates similarly to a blocking oscillator. Transmitter. As shown, transductors 4, 5 ... may be switched selectively into circuit by a switch 3 when the similar A.C. windings 10, 11 are series connected with the output transformer 6 across a 50-cycle supply 1-2. The windings 10, 11 conduct during alternate half-cycles of the supply by virtue of rectifiers 12, 13 and magnetize the core in the same sense, the reactance of these windings being varied periodically by similar opposed control windings 14, 16 fed from the rectified output of transformer 6, and series connected, respectively, with a resistor 15 and inductance 17, the modulating frequency being determined by the control circuit constants. The transductors 4, 5 modulate the 50-cycle input at different frequencies which are doubled in the rectifier bridge 7, the modulated output therefrom being fed through a series resonant filter 8 to the line R, R. An additional primary winding 18 of transformer 6, fed directly from the supply, compensates for the magnetizing current of the operative transductor so that in the line R, R the modulation is 100 per cent. Alternatively, a single transductor may be used, the coupling of which is changed by altering its control voltage or circuit elements to produce the desired modulation frequencies. Receiver, Fig. 2. The signal carrier frequency is filtered at 24 and applied through a rectifier 25 and amplifier 26 to relay coils 27, 28 over resonance circuits 29, 30 tuned respectively to the modulation frequencies of transductors 4, 5 and rectifiers 31, 32 so that relay 27 or 28 responds according to the transductor 4 or 5 connected in circuit at the transmitter. An L.C. combination 33, 34 filters out the D.C. and unwanted harmonics from the amplifier output. In a modification, Fig. 3 (not shown), the relay coils 27, 28 act on opposite ends of a bar armature pivoted at its centre to close one or the other of two control circuits. A third circuit may be closed by the armature in its neutral position. Alternatively the inductance 33 may function as a zero-current relay.

IPC: C08J3/09
Filed: 1975-05-14
Abstract: There is described a process for the in situ preparation of stable dispersions of polyurea and/or polyhydrazodicarboxamides in hydroxyl-containing polyethers. These products are prepared by reacting (1) organic polyisocyanates with (2) primary and/or secondary amino group-containing polyamines and/or hydrazines and/or hydrazides, in a high molecular weight polyether which has at least one hydroxyl group with the components (1), (2) and (3) being passed continuously into a continuous mixer at such a rate that the average residence time (dwell time) in the mixer is less than 10 minutes. The equivalent ratio of components (1) and (2) is between 0.8 and 1.05. The dispersions thus prepared are non-sedimenting and combine a relatively high solids content with a relatively low viscosity. The size of the dispersed particles is usually below 1  mu . Owing to these properties, they are suitable for preparing polyurethane foams.
