Abstract: 674,290. Echo-sounding and distancemeasuring apparatus. SIMONSEN RADIO AKTIESELSKAPET. June 20, 1950. [June 24, 1949] No. 15430/50. Class 118 (ii). [Also in Group XIX] In an echo-sounding recorder of the type wherein the driving shaft of the instrument rotates to make a recording pencil pass across a moving paper tape the mechanism is arranged so that the pencil performs a rectilinear movement across the paper tape. The rotating shaft 1 carries an arm 4 on which a carrier 7 for the pencil 3 is pivoted at point 5. The point 8 on the pencil carrier 7 is guided in a path 9 by means of a roller 10 adapted to follow a correspondingly formed rail, or the roller 10 may be spring-loaded to keep it in engagement with the circumference of a cam disc conforming to the path 9. The curvature of path 9 is such that the carrier 7 in moving from the position shown in full lines to that shown chaindotted causes the pencil 3 to move in a straight path across a paper tape 2, the pencil then returning to its first position by a nondescript path (not indicated). The useful part of the guide 9 may consist of different radii of curvature to give the pencil a greater velocity in the earlier part of its travel. The guided point 8 may be on the same side of point 5 as, or even coincide with, the pencil 3.

Title: Process and apparatus for creating a flow of gas in apparatus for the separation of suspended particles from gaseous fluids
IPC: B03C3/66
Filed: 1940-10-19
Abstract: 546,617. Moving gases. DEUTSCH, W. Oct. 19, 1940, No. 15471. [Class 8 (i)] [Also in Group XL] Apparatus for separating suspended particles from a gas, such as air, comprises a flat disc 12 with spaced needles 13 around its periphery directed towards two discs 14 substantially parallel with the disc 12 and provided with central apertures 15. The discs are positioned relatively to one another by insulators 18 and brackets 19, and are oppositely charged to high potential, whereby a corona discharge takes place between the points 13 and the peripheral edges of the discs 14. The gas is thereby ionized and caused to flow inwardly between the discs where they are subjected to the non-discharging fields between the central parts. The particles are deposited on the discs 14 and the cleaned gas passes out through the central openings .15, which are preferably covered with gauze 16 to prevent discharges from the edges. The outer peripheries of the discs 14 are curved outwardly to provide minimum resistance to the flow of gas with maximum corona effect. The potentials may be obtained from an ironless Testa coil and thermionic rectifier, with a shunt condenser between the discs. The primary is connected to the source of current through a condenser and electromagnetic interrupter. The discs may be mounted on a rod fitting in a socket 20 and carried around by an operator bearing the electrical equipment in a pack.

Title: System for recirculation of exhaust gas of an internal combustion engine
IPC: F02M26/73
Filed: 1974-04-10
Abstract: 1462998 IC engines - exhaust gas recirculation ROBERT BOSCH GmbH 10 April 1974 [14 April 1973] 15852/74 Heading F1B The invention relates to a system for recirculating exhaust gases of an I.C. engine which comprises a valve 1 for controlling the amount of exhaust gas recycled in dependence on the pressure in the inlet manifold 12 of the engine. The recirculating valve has an inlet connected by line 16 to the exhaust manifold 15 of the engine indicated at 14, and an outlet connected by line 16 to the air intake manifold 12 of the engine at a point downstream of the throttle valve 13 of the engine. A by-pass line 33 is provided for by-passing the throttle valve 13, the by-pass line comprising a throttle 34 by which the amount of by-pass air and thus also the idling speed, may be controlled. The by-pass air is utilized to cool the exhaust gas recirculating valve. The valve comprises a cupshaped valve member 27 which engages a seat 28 formed in a tube portion 29 connected to the valve body 30. The valve-member 27 is connected by a rod 26 to a control diaphragm 20 mounted in a chamber 21. The diaphragm is acted on by a spring 24 whereby the valve 27 is normally held against the seat 28. The space 22 above the diaphragm is connected by line 23 to the induction manifold 12 in the vicinity of the throttle valve 13, and the space below the diaphragm is connected to atmosphere through vent 25. The line 23 is connected to the induction manifold adjacent the portion 35 of the throttle valve which moves in an upstream direction as the valve is opened; thus when the throttle valve is closed, the pressure in the space 22 is equal to atmospheric pressure and the valve 27 is closed; as the throttle valve opens, the pressure in the induction manifold falls and the valve 27 is thus opened; when the throttle valve is fully open the pressure is again increased and the valve 27 is thereby closed.

Patent GB-497026-A (GB)
Title: Improvements in or relating to starting apparatus for internal combustion engines
IPC: F02N15/02
Filed: 1937-06-11
Abstract: 497,026. Turning-gear. BOSCH AKT.- GES., R. June 11, 1937, No. 16198. Convention date, June 11, 1936. Addition to 493,047. [Class 7 (v)] In an engine starter in which a pinion 18 is axially displaceable on a threaded shaft 14 driven through a free-wheel clutch 22 and is locked when fully in mesh with an engine member 26 until the starting-motor is de-energized, the locking member 36 also engages the threaded shaft 14 and is utilized to displace the shaft and pinion axially until the pinion is partly in mesh. As shown, clutch plates 22 are disposed between a nut 19, engaging threads 17 on the shaft 14, and a drum 21 keyed to the shaft 11 of the starting-motor and provided with a spring abutment 23. The threaded shaft 14 is axially displaceable by means of a rod 27 having a peripheral groove 42 with inclined faces for engagement with a ball 36 in a radial bore in the shaft 14. On actuating a switch 45, the rod 27 is moved axially by means of an electromagnet 40 and a lever 28, so that the pinion is brought partly into mesh with the engine member 26. A collar 25 on the shaft 14 then engages the spring abutment 23 to bring the clutch 22 into engagement, and a contact bridge 30 on the core of the electromagnet 40 closes the circuit of the starting motor. Rotation is thus transmitted to the shaft 14 and the pinion 18 moves into full mesh with the member 26. It is then retained by the ball 36, which is moved outwards by the face 34 when the rod 27 completes its forward movement under the action of a spring 32. The parts are held in this position until the electromagnet 40 is switched off, overrunning of the pinion 18 by the engine being allowed by the clutch 22. The Specification as open to inspection under Sect. 91 comprises also a modification in which the clutch 22 is dispensed with and the starter pinion is threaded on the axially displaceable hollow armature shaft of the starting motor. When the pinion is fully in mesh with the engine member, a locking ball is moved radially to engage the pinion by the inclined face of a collar on the end of a fixed rod within the armature shaft. A buffer spring cushions the meshing movement of the pinion. This subjectmatter does not appear in the Specification as accepted.

Title: Refractometers
IPC: G01N21/43
Filed: 1945-06-25
Abstract: 608,132. Refractometers. SILGE, M. June 25, 1945, No. 16199. [Class 97 (i)] A refractometer which employs the principle of total reflection comprises a telescope housing having mounted, at one end thereof, a unitary prism composed of a series of sections of different refractive powers and, near the opposite end thereof, an equal series of scales, an equal series of optical systems being disposed between the scales and the prism so that one optical system and one scale co-operate with each prism section to cause rays refracted by the latter to form an image on the scale cooperating therewith. The prism sections may be replaced by a simple prism and a series of reflectors mounted at different inclinations to the exit face of the prism. As shown in Fig. 2, the refractometer comprises a prism 3 having three sections 12-14 as of different refracting angles and mounted at the end of a telescope housing (not shown) which encloses objectives 15-17, field lenses and scales 18-20 and eye lenses 4. The objectives and scales are so disposed that each co-operates with one prism section, the three scales indicating consecutive values of refractive index. In using the refractometer to determine refractive indices lying within a certain range, this range is divided into three sub-ranges, one each of which is dealt with by each of the prism sections, and the refractive index of the sample, which is placed on the common entrance face 10 of the prism sections, is found by reading on the appropriate scale the position of the image formed by the ray, emerging from a particular prism section, which corresponds to the ray having grazing incidence with the face 10. When the telescope housing is disposed at an angle to the prism 3, a reflector may be used to direct the rays emerging therefrom on to the appropriate scale. In another form, an ordinary prism 28 and reflection 29-31, fixed at different inclinations to its rear face as shown in Fig. 11, are used to effect the same purpose as the prism 3.
