Title: Automatic solid fuel stokers
IPC: F23K3/00
Filed: 1934-03-23
Abstract: 421,025. Boiler furnaces; mechanical stokers. NAAMLOOZE VENNOOTSCHAP VERWARMINGS MAATSCHAPPIJ, 5, Westerstraat, Utrecht, Holland. March 23, 1934, No. 9173. Convention date, March 30, 1933. [Class 51 (i)] A solid fuel stoker device includes superimposed communicating chambers (as shown there are two chambers 4 and 8) with a reciprocable piston within each chamber and means for operating the pistons so that the upper piston 5 will move fuel from its chamber into the lower chamber 8 and the lower piston 10 will subsequently discharge the fuel into the furnace, the lower piston sealing the opening 9 between the two chambers during the propulsion of fuel into the furnace. Fuel is fed to the upper chamber from a bunker (not shown) by way of a hopper 3. The pistons are of unequal cross section, the upper piston being the smaller, and they are driven from a motor 20 through link mechanism so as to operate in alternate manner. The chamber 8 communicates with the combustion space 1 at the top of a water-cooled grate 2 which is provided at the rear end with a rotary slag breaking device comprising arms 14 operating between the ends of the grate bars. Slag is removed by a screw conveyer 12, the slag breaker and conveyer being driven from the motor 20 which may be thermostatically controlled. As shown the apparatus is in the form of a detachable unit mounted on balls or rollers and adapted to be coupled to an existing boiler. The combustion chamber is provided with a half-cylindrical water jacket 15, an air inlet 18, ash pit 19 and water cooled bridge 21. A modified form of stoker has a greater number of chambers and the pistons are operated so that each intermediate piston closes the communication between its chamber and one of the adjacent chambers while the communication with the other adjacent chamber is open to permit the passage of fuel.

Title: Improvements relating to electric motors and to control systems therefor
Inventor: BINNEY ERIC ALTON

Abstract: 736,716. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd. March 26, 1954 [April 2, 1953], No. 9192/53. Class 38 (3). A traction motor 10 has a series field winding divided into sections 10a, 10b, a non- inductive resistor 11 being connected across the section 10b. The motor is supplied from an A.C. source through rectifier 13 and, on full-field operation, contacts 14, 15 only are closed, whilst, on weak-field operation, contactors 15, 16 are respectively open and closed. The ohmic value of the resistor 11 is high compared with the resistance of the section 10b so that, during fullfield operation, there is no substantial reduction of the total field-strength. In addition to the by-passing action of the resistor 11, the section 10b acts as a damping winding since the undulating current-component in the section 10a produces, by transformer-action, an opposing component in the section 10b, the resistor 11 acting as, a load for this latter component. Thus the pulsating flux is reduced, so decreasing sparking at the commutator and heating of the field coils. The damping effect of the winding 10b is still effective under weak-field conditions. In Fig. 2 (not shown) two series motors similar to the motor 10 are supplied with rectified current from a tapped transformer, the motors being accelerated in steps by increasing the supply voltage and removing a graduated armature resistance. In changing from the full-field to the weak-field position, a part of the armature resistance is re-introduced, and, on the final weak-field stop, the armature resistance is again short-circuited. The motor may be accelerated under the control of a currentlimit relay. In a modification of the arrangement shown, a further non-inductive resistance is also connected across section 10a of the field winding.

Title: Improvements relating to ethyl cellulose moulding compositions and articles producedtherefrom
IPC: C08K5/101
Filed: 1945-04-13
Abstract: <PICT:0590130/IV/1> A moulding composition comprises ethyl cellulose, of ethoxy content preferably within the range of 45.5-46.8 per cent, plasticised with 15-20 per cent of a mixture of two plasticisers, one of which is a refined mineral oil and the other a long chain fatty-acid ester, the proportion by weight of oil to ester ranging from 1 : 3 and 1 : 1.  Esters specified are butyl stearate or palmitate, amyl stearate and dibutyl sebacate.  A mineral oil fraction of distillation range 276 DEG  to 405 DEG  C. may be used. About 0.5 per cent diphenylamine may be added to the composition as a stabilizer.  Contaminants in the commercial fatty acid esters, which may impart taste or smell to liquids in contact with the moulded product, may be removed by treatment of the ester with hot water or steam followed by washing with aqueous sodium bicarbonate or ammonia and then water.  In an example, 12 parts of butyl stearate are compounded with 100 parts of ethyl cellulose, of 45.5-46.8 per cent ethoxy content, 5 parts of "Fractol A" ("Fractol" is a Registered Trade Mark) and 0.5 parts diphenylamine.  From such a moulding stock the water-bottle shown in the drawing may be made.  The separately moulded parts 1 and 2 are cemented together along the line 3, the end surfaces being first softened in 95 per cent aqueous alcohol.

Title: A method of and apparatus for trimming metal blanks
IPC: B23D1/20
Filed: 1919-04-12
Abstract: 149,032. White, A. E., (Waterbury Farrel Foundry & Machine Co.). April 12, 1919. Bolts; nuts.-Nut blanks &c. are trimmed to polygonal section by relative longitudinal axial movement of the blank and die, so that the peripheral surface of the blank is trimmed by angular shearing cuts operating throughout the entire axial length of the surface without tearing the metal at the end of the cut. The blank is forced through a die 10, Fig. 1, the curved cutting edges 15 of which are at the bottom of a recess 11 so that the chip is prevented from spreading and flows in a direction parallel to the direction of cut. The cut blank may pass through the die or be ejected by a punch 17. In another form the recess 11 is countersunk. In the die shown in Fig. 8 angular cuts 12a radiate from the opening and form angular cutting edges 201<a>. In a modification the top of the die has a conical face 11<b>, Fig. 17, and the cutting edges are formed by providing on the surface a number of flats 12b intersecting the opening 10<b> at acute angles. The' die shown in Fig. 20 is made up of several trapezoidal members 12<c> held in the body 10<c> by screws. The top of each member is cut away at an angle to form cutting edges 13<c>, and planishing edges may be formed on the cutters. In Fig. 28 a set of planishing rollers 12<d> are arranged behind the cutting die 14<d> and may be adjusted by means of loose blocks between the rollers and a retaining ring 11<d>. In a further modification two opposing dies 10<e>, 30<e>, Figs. 30 and 33, cut nearly half-way through the blank after which the blank is pushed through the die 10<e> and a planishing die 14<e> by the rod 36<ee>. A second cutting die 40<e> may be arranged in line with the die 10<e>. The planishing die 14<e> comprises a number of projections 16<e> curved in cross-section with their innermost lines forming rubbing surfaces parallel to the sides of the die opening 11<e> but slightly nearer the axis of the die. The die 10<e> may be adjusted angularly by two screws 18<e> engaging diametrically opposite shoulders on the die, and the die-block 17<e> may be adjusted horizontally and vertically. The die 30<e> may be adjusted by means of a screw 35<e>. In Fig. 38 two dies 10<f> and 14<f> are in series, and the chip from the die 14<f> passes through recesses 18f in the under side of the die 10<f>.

Title: Improvements in or relating to couplings for railway and like vehicles
IPC: B61G1/08
Filed: 1927-04-05
Abstract: 296,795. Mitchell, J., and Cossey, J. C. G. April 5, 1927. Couplings, automatic. - In a Norwegian hook coupling means are provided for raising the hook to a disengaged or ready-for-uncoupling position and maintaining it in such position while the buffer faces still remain in contact, while the separation of the coupler heads in the actual uncoupling causes the parts to re-set themselves to a ready-for-coupling position, for the means being associated with the hook for setting it permanently in a non-coupling position so that the buffing faces may come into contact without effecting a coupling as, e.g., in shunting operations. In the central coupling-buffer shown, in which the usual draw and buffing springs q are associated with each coupler-head, the coupler-- head a fitted with the pin or coupling-block h is provided with a cam w mounted on a rotatable spindle x and so shaped that when rotated in an anti-clockwise direction it first causes the hook p to be lifted owing to the point p<2> thereof passing along the surface w<2> of the cam, and finally the point p<2> passes over the point w<3> of the cam and rests upon the inclined surface w<4> as shown in Fig. 3, i.e., in a ready-for-uncoupling position. When the actual uncoupling takes place, the hook rides up the inclined surface w<4> and the cam is released to fall back again into a ready-for-coupling position, Fig. 1. The other coupler-head b carrying the hook p may also be provided with an operating cam y, which is mounted on a pin z movable in an elongated slot b<1> in the couplerhead, so that, when the cam is rotated in an anticlockwise direction, an abutment y<2> raises the hook, then the pin z slides rearwardly in the slot b<1> and allows a recessed abutment y<3> to engage a projection b<2> on the rear of the buffing face. In this condition, the hook is permanently supported in a raised position, and its weight tends to maintain the parts y<3>, b<2> in engagement. The position of each of the coupling-elements may be observed by noting the position of the cam operating- handles w<1>, y<1>, or separate, indicating pointers may be attached to the spindles x, z. Specifications 202,233 and 236,417 are referred to.
