Title: Improvements in or relating to means for reversing screw propelled boats
IPC: B63H5/14
Filed: 1923-11-14
Abstract: 218,550. Jarvis, G. F., and Gee, G. L. Nov. 14, 1923. Propeller guards; propelling, steering, and manoeuvring by screw propellers; rudders.-For reversing boats, a horizontally pivoted vane is mounted in a fixed casing surrounding the screw propeller. A casing 3, Fig. 1, is fixed to the hull 1 at 6 and to the skeg 5 at 7 so as to surround the propeller 4. At the after end, a circular vane 9 is mounted on a horizontal axis 10 which is moved from the horizontal position to the vertical for closing the end of the, casing and reversing the propeller stream by links 11, 12 attached to vertically slidable control rod 13. The casing may be stiffened by a ring where it carries the trunnions, and the vane may be stiffened by ribs. In a modification, the casing 3, Fig. 9, is recessed at 21 at the forward end and a short inner casing 22 similarly recessed at 24 is fitted, the annular passage 23 betwen the casings forming a return flow passage on reversal. The vane may be made in two parts with a small gap between them to facilitate attaching the controls. Specification 196,640 is referred to.

Title: Improvements in or relating to tanning
IPC: C14C3/20
Filed: 1935-10-18
Abstract: A tanning-agent is prepared by reacting a chlorophenol with formaldehyde and sulphuric acid.  Preferably, 2 molecules of a chlorophenol are reacted with 2 molecules of sulphuric acid and the product is treated with about 1 molecule of formaldehyde and partly neutralized, but the order in which the reagents are taken may be varied.  An example is given in which dry o-chlorophenol is treated with oleum at 80--100 DEG  C. and the product is diluted, treated with formaldehyde at atmospheric temperature, and then partly neutralized with caustic soda solution.  Other chlorophenols, including chlorocresols and other chlorinated homologues of phenol, may be used in place of o-chlorophenol. Specifications 291,245 and 337,808, [both in Class 2 (iii)], are referred to.

Abstract: 859,353. Self-granulating mixed fertiliser processes. LUMMUS CO. Sept. 9, 1958 [Sept. 18, 1957], No. 28850/58. Class 111. A continuous, self-granulating process for the manufacture of mixed fertilisers comprises intimately mixing and advancing exothermically-reactive, fertiliserforming, compounds and water into a second zone where a current of drying gas is passed over the mixture to remove moisture, a vapour seal being maintained between zones by means of the mixture itself. An apparatus for carrying out the process is illustrated in Fig. 1. Sections 2, 3 and 5 of a compound double pug mill 1 are arranged in ascending series with the junctions between sections forming with the reaction beds 4, 6 and 8 seals between the sections. Solid reactants are supplied continuously to the upstream end of section 2 by a feeder 14 and liquid reactants by pipe 15. A fluid ammoniating agent is injected by sparger 9 into the reaction mixture in section 3. Section 5 is provided with an exhaust duct 18 connected to the input side of an exhaust fan 19 which produces a flow of air drawn in through outlet 7 and over moving bed 8. The ammoniating agent may contain ammonium salts, e.g. nitrate or sulphate which react with potassium salts e.g. chloride, nitrate or sulphate which may be introduced at 14 or 16. Examples describe the preparation of various mixed fertilisers.

[Also in Group XXXV] A control system for a D.C. electric motor M having a variable voltage supply, by which the energization of the field winding 12 decreases as the armature volts increase includes a phaseshifting arrangement comprising a transformer secondary winding 25 having three taps 34, 24, 21 across the two outer 34, 31, of which, are connected in series an inductive circuit 33 and a circuit 32 which includes a saturable inductor 20, 21, whose impedance is varied by D.C. to change the phase of current supplied to a load 28 connected between the intermediate tap 24 and the junction D of the two circuits. The load 28 is a transformer supplying A.C. to the grid 36c of a valve 36 which with diode 38 forms a full-wave rectifying arrangement supplying field winding 12 of the D.C. motor M with D.C. from the transformer secondary winding 25. When the direct volts supplied at 13, 14 to the armature of motor M are below a certain value, no current flows in D.C. winding 16, the inductor 20, 21 then has a maximum value, the network 32 appears as a high resistance and the grid of valve 36 is energized early in the supply halfcycle so that winding M receives maximum current. When the armature voltage of the motor rises above the set value, valve 18 conducts, current flows through winding 16 to vary the value of inductor 20, 21 and the resistive value of network 32 falls so that valve 36 fires later in the half-cycle and each pulse of current supplied through it to winding M is reduced in value.

Abstract: 837,732. Rolling. MICHIGAN TOOL CO. Sept. 20, 1957 [March 13, 1957], No. 29731/57. Class 83 (4). In a method of forming projections of a predetermined width, e.g. helical gear teeth, splines, oil grooves, &c. on the external surface of a workpiece, a rack-type tool having a narrow band of teeth of a shape conjugate to the projections is rolled along a helical band on the surface without relative axial movement between the tool and the workpiece, so that successive convolutions of the helical band overlap on the workpiece to extend the projections to the said predetermined width. A tube is rotatably supported at one end by a rotatable mandrel and at the other end by a spindle or a tail stock. Hardened steel racks or platens 29, 31 mounted on carriages 27, 28 and reciprocated on tracks 25, 26 by cylinders 32, 33, each have a diagonal band or zone 37, Fig. 3, of conjugate-forming teeth 44, 48, Fig. 4, the teeth rolling along a helical band on the surface of the tube when the racks reciprocate tangentially to the tube to progressively form splines of a predetermined width by cold-rolling. The teeth 48 at the leading end of zones 37 either have a downwardly-inclined pitch line or have the tops ground off so that the racks engage the tube smoothly. Gripping teeth 51 in zones 36 of the racks have a similar form to teeth 44, 48 but are ground down to the pitch line so that they partially form the splines prior to the action of the teeth 44, 48 and also rotate the tube. Conjugate teeth 52 in the zones 38 of the racks have their tops slightly ground off and burnish the fully-formed splines or projections. The distance apart of platens or racks 29, 31 is adjustable by gibs 34, 35 to suit various sizes of work. Each rack may have more than one band of fully conjugate teeth inclined in the same or opposite directions. Specification 797,860 is referred to.
