Title: Improvements in or relating to internal combustion engines supercharged by means of exhaust-gas turbo blowers
IPC: F02B37/02
Filed: 1950-11-28
Abstract: 700,182. Supercharging. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.- GES. Nov. 28, 1950 [Jan. 3, 1950], No. 29103/50. Class 7(2) In a four-stroke internal-combustion engine 14 supercharged by an exhaustgas turbo-blower 12, wherein the exhaust gases are arranged to flow through at least one duct 1 or 2 of predetermined length to a receiver 5, a diffuser 3 or 4 is provided between the receiver and the receiver end of the duct, the receiver outlet being connected to convey the gases to the turbine inlet so that in operation the pressure in the turbine inlet is more nearly constant than the pressure in the duct with the result that negative pressure impulses are reflected from the receiver 5 along the duct to assist in exhausting the engine cylinders. The engine has two exhaust ducts 1, 2 each of which is connected to three engine cylinders, whilst the exhaust gases pass from the receiver 5 through pipes 6, 7 to act upon the turbine rotor 8, which drives the blower 12 that supplies air or mixture to the engine 14. When using a single duct the individual pressure impulses and the returning negative pressure impulses assist one another. In a modification, the diffusers have non-return valves incorporated at their point of entry into the receiver to prevent exhaust gases passing back into the exhaust ducts.

Title: Improvements in or relating to dynamo electric direct current generators
Inventor: WRATHALL ROBERT WILLIAM
IPC: H02K23/20
Filed: 1948-11-09
Abstract: 655,753. Exciting dynamo-electric machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 9, 1948, No. 29131. [Class 35] In a cross - flux generator having more than two pairs of poles and brushes, more than two stages of amplification are obtained by successively advancing or retarding the quadrature cross-flux produced by the primary excitation at each stage by one pole-pitch. The invention is shown for a twopole machine having eight polar sections 1-8 with field windings 21-24 and commutator brush pairs 11-14. The initial control field is represented by vector 31 and the resultant voltage appearing across brushes 11 would normally produce a cross-flux 33 which would be used for the second stage of amplification. In this invention, however, these brushes are connected to windings 21 on poles 2 and 6 which have the effect of turning the flux round through one pole-pitch into the position shown as 34. This flux now becomes the start of the next stage and produces a voltage across brushes 12 which feed windings 22 on poles 3, 7 to pull the resultant quadrature flux 36 into position 37. This process is repeated to produce fluxes in positions 32 and finally a flux 35 in opposition to the original control flux 31, interference between these two being overcome by means of compensating windings. The amplified power is derived by connecting the load circuit in series with field windings 24 which turn the final flux from position 34 to 35. The machine may have an even or odd number of pole pairs, in the latter case recesses being necessary in the pole faces opposite the brushes to provide a commutating zone. The windings may be on salient poles or may be set in slots.

Abstract: 1,138,787. Power-assisted steering mechanism. DAIMLER-BENZ A.G. 23 June, 1967 [24 June, 1966], No. 29193/67. Heading B7H. [Also in Division G3] In hydraulically-assisted vehicle steering mechanism including an axially-displaceable control valve 5, which is subjected as described in Specification 1,111,370, to a centring force provided by a spring after a progressive hydraulic centering force provided by a respective reaction piston 21, 22 in proportion to the servo pressure has reached a predetermined maximum, an hydraulic centring force smaller than that initially provided but increasing proportionally to the servo pressure augments the constant force of the spring. Each reaction piston 21, 22 comprises a first piston element 28 slidable in a second piston element 29 against the resistance of a pre-loaded spring 33. The hydraulic force exerted on the element 29 is initially transmitted through the spring 33 to the element 28 which exerts against the valve housing the total hydraulic force acting on both elements. When the servo pressure is such that the force on the element 29 exceeds the pre-load in the spring 33, the element 29 moves forward to engage a retaining ring 37 whereupon the element 28 exerts only the hydraulic force acting directly thereon plus the load in the spring 33.
