Title: Improvements in or relating to dynamo electric machines
IPC: H02K23/36
Filed: 1945-01-12
Abstract: 587,663. Exciting dynamo electric machines. ENGLISH ELECTRIC CO., Ltd., and BINNEY, E. A. Jan. 12, 1945, Nos. 4304/46 (divided out of 579,570) and 23299/45. [Class 35] A D.C. motor has two armature windings with corresponding field windings wound for different pole numbers, one armature winding co-operating with a separately excited field winding and energizing a field winding linked with the other armature winding which is also subjected to a field produced independently of the exciting armature winding. The motor may give constant speed when operating on a varying voltage supply and be therefore suitable for driving a generator. In the form shown, the motor has armature windings connected to commutators 11, 13 in a stator with four main polar projections with separately excited winding 20 and shunt (or series) winding 19 producing a two-pole field linking the winding of comutator 11 while the armature winding of commutator 13 which excites winding 20 is linked by a four-pole field produced by separately excited opposing windings 21a and 21 the latter fed from sub-exciter 43 on the shaft of the motor and the A.C. generator 35. When a constant voltage source is available for field 21a, and generator field 36, winding 21 may be connected across the A.C. generator through a rectifier. In the case of other drives, field winding 21 may be controlled by a governor-operated rheostat and/or a non- linear resistor and the motor may also have a damping or compensating winding while the commutator 11 may also have a pair of short circuited brushes. Specification 560,531 is referred to.
Patent GB-416378-A (GB)
Title: Improvements in or relating to processes for treating oleaginous seeds, fruits and other vegetable material
IPC: C11B1/16
Filed: 1933-02-13
Abstract: Oleaginous seeds, fruits and other vegetable material are subjected in a closed vessel to the action of steam at a pressure above atmospheric generated by the natural moisture contained in the material by heating without any steam from an external source being admitted into the vessel.  The material is preferably agitated during the treatment, which usually takes place at a pressure of five to ten pounds above atmospheric, the agitator being run at a high speed initially to remove the pericarp of fruits and then at a slower rate until the close of the operation. When the oil cells have been fractured the accumulated steam is allowed to escape and any remaining moisture evaporated under vacuum or atmospheric conditions.

Abstract: 385,133. Distributers for manures and seeds. MACALISTER, J., 329, Dee Street, Invercargill, New Zealand. Feb. 16, 1932, No. 4542. Convention date, Feb. 25, 1931. [Class 6 (i).] A distributer comprising a hopper mounted on a travelling frame and constructed with an adjustable rear delivery slot is provided with means for feeding the material from the hopper consisting of inclined discs E mounted on a rotary shaft F inside the hopper A and a reciprocating plate G having its upper edge in the delivery slot B. The discs E just clear the bottom of the hopper as shown, and their inclination is such that they overlap. The thin plate G is inclined as shown and is reciprocated at a medium rate. The timing may be such that the plate G is always moving in a direction contrary to the lateral movement of the peripheries of the discs. The top edge of the plates G may be slotted as shown, so that small quantities of manure may be delivered even when the slot-adjusting plate D is closed down upon it. The shaft F and plate G may each be in two sections driven independently from the two travelling wheels P, and the discs on the two shaft sections may be inclined oppositely. The shaft F may be driven by a chain r and a clutch, and the plate G may be provided with a forked bar S<1> engaging an inclined cam S on the shaft F. The slot-adjusting plate D fits beneath guide straps H and the plate G is supported in guide brackets N. The plate D is moved by rocking a shaft M provided with crank arms K connected by links J to the plate. The apparatus may be combined with drills &c.

IPC: F23D11/10
Filed: 1920-02-14
Abstract: 149,888. Haddan, R., (Corning Glass Works). Feb. 14, 1920. Polishing.-Relates to apparatus for fire-polishing pressed glassware before it is removed from the moulds, and consists in providing a burner having a primary mixing-chamber and a secondary mixing-chamber, a bell attached to the secondary mixing-chamber and adapted to receive the glassware to be polished, and means for deflecting the combustible mixture from the burner to produce a swirling effect inside the bell. The device can be used for finishing the edge of ware formed of hard glass. As shown, it is arranged for use with liquid fuel, but it may be adapted for gaseous fuel. It consists of a fuel-intake pipe 18 co-axial with another pipe 13 which, together with a short extension 23, forms the primary mixing-chamber. An air-inlet pipe 20 is connected to the rear end of the pipe 13, and a perforated cap 25 screwed on to the end of the extension 23 breaks up the mixture of fuel and air as it is forced through. An outer tube 11, provided with a secondary air-inlet 29, surrounds the pipe 13 and forms a secondary mixing-chamber which has a bell 37 and a cap 32. The cap 32 has openings formed in its side wall, the opening being inclined to the circumference of the cap so that the flame is caused to swirl around the inside of the bell. A conical portion 35 on the inside of the cap assists in deflecting the mixture through the openings.

Abstract: 525,034. Capsule closures. MAREK, A. J., and KORK-N-SEAL, Ltd. Feb. 13, 1939, No. 4643. [Class 125 (iii)] A cap for bottles or other containers has two portions, an outer metallic part a provided with a tab b and an inner part c of parchment, paper or the like; the inner part c is substantially coextensive with the outer part a but it does not extend beneath the tab. After the removal of the cap the inner part c may be used as are-closure. During manufacture the flat strip d, Fig. 6, from which the parts c of the caps are cut, is led between rollers e to tools on the line AA which cut away the portions i corresponding to the tab position. It then passes between the rollers f which also feed the metal strip g. The two strips pass together to tools on the line BB which stamp out the two parts of the cap. In a modification, the outer portions a with their tabs b are fed to a holder 2, Fig. 9, opposite a die 3 over which the paper 4 is fed. The hollow stamping member 5 is operated to stamp out the disc for the inner cap portion c which is then pushed by the punch 6 into the metal part a of the cap.

Abstract: 711,278. Jet-propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. March 2, 1951 [June 19, 1950], No. 5144/51. Class 110(3) [Also in Group XXVII] A pulse jet engine exhausts through a convergent-divergent pipe opening into a large capacity exhaust chamber which has a diverging inlet connected to the pipe and opens freely to atmosphere, the divergence of the inlet being greater than that of the divergent part of the pipe. In the arrangement shown, air is admitted into a combustion chamber 1 through valves 3 and exploded by means of fuel injected through the pipe 4. The gases are discharged through a converging section 5 followed by a diverging section 6 into a large section cylinder 7 which is open at the rear 8. The pipe 7 has a natural frequency of vibration which may be tuned experimentally to the frequency of the pulse jet by suitably regulating the length L of the cylinder 7. It is stated that the cylinder 7 acts as a thrust augmentor in that air which enters the cylinder 7, after the previous exhaust, is carried out by the gases from the succeeding explosion. It has been found.that if the area of the cross-section of the cylindrical part 7 is greater than three times the area of the cross section of the neck of the pipe and the length e of the cylinder 7 is greater than a quarter of the length L between the neck of the nozzle and the rear opening 8 of the chamber 7 a considerable increase in thrust is obtained. The combustion chamber 1 may be the cylinders of an internal combustion engine. The chamber may be made conical in shape. It is stated that the presence of the chamber 7 causes a lowering of the static pressure upstream in the chamber 1 which facilitates its refilling. In a modification the chamber is united to the outlet of the nozzle by a divergent section. Specification 653,629 is referred to.
