Title: Regulating the scavenging of a free piston engine
IPC: F02B71/00
Filed: 1948-02-25
Abstract: 652,110. Free-piston engines and gas generators. TRIGGS, W. W. (Lima-Hamilton Corporation). Feb. 25, 1948, No. 5580. [Classes 7(i) and 7(ii)] In a free-piston engine or gas generator comprising a combustion chamber having a connection with a compressor cylinder for supplying scavenging air under pressure to the combustion chamber and having an exhaust passage, control means are provided adapted to vary the scavenging air pressure in accordance with the differential of the scavenging air pressure which is derived from the connection and the pressure of the gas in the exhaust passage. As shown, a throttle valve 15 is arranged between an exhaust passage 14 and a pipe 16 connected to a scavenging air receiver 11. The throttle valve is operated by a piston 17 and rack 19 the piston being acted on by the exhaust pressure transmitted through a passage 23, the scavenging air pressure transmitted through a passage 21 and a spring 24 which can be adjustably loaded. Thus the throttle controls the scavenging air pressure in accordance with the exhaust pressure and the scavenging air pressure. In a modification the valve 15 instead of being between the exhaust passage and the passage 16 is arranged to control the suction air supply to a compressor cylinder 4. In a further modification the valve 15 controls a connection between the scavenging receiver and the sucton side of the compressor. The arrangement provides for the reduction of the scavenging pressure when the exhaust pressure is reduced as at idling or light load. The control of the scavenging pressure may be effected in several ways including byepassing a portion of the scavenging air directly to the exhaust conduit or cutting down the amount of air available for discharge into the scavenging receiver from the air compressor or by byepassing a portion of the compressed air as it is discharged from the compressor and returning it to the intake side of the compressor cylinder. The spring 25 provides for complete closure of the valve 15 when desired. The effect of the spring 25 is to permit the attainment of the maximum scavenging receiver pressures prior to the attainment of the maximum exhaust receiver pressure.

Title: Improvements in stereogrammetric plotting or mapping apparatus
IPC: G01C11/00
Filed: 1936-02-27
Abstract: 468,524. Stereogrammetric apparatus WILD SURVEYING INSTRUMENTS SUPPLY CO., Ltd., H., and WILD, H. Feb. 27, 1936, No. 5894. [Class 97 (i)] In a stereoscopic apparatus for plotting maps &c. from photographs and having object and image space guides and universally adjustable plate carriers, the carriers remain stationary during plotting and each half of the stereoscopic viewing system contains a movable arm with an adjustable optical system, one end of the arm being connected to the image space guide and the other end being mounted, on the plate carrier. The apparatus shown is provided with plate carriers 1, 2 each bearing two plates 3, 4 such that 3, 3 and 4, 4 are two stereoscopic pairs. The carriers 1, 2 are mounted so as to be adjustable about axes C-C in frames 13 which are adjustable about vertical axes B-B in frames 12 so mounted that they can be rotated about the horizontal axis A-A. The axis C-C is represented by a hollow axle 14 which carries, at its intersection with the axis B-B, a mirror 19 to deflect the rays passing through the axle 14 along the axis A-A. Each of the carriers 1, 2, has bearings 20, 20<1> for the movable arms 21, 21<1> of the viewing system, and each of these arms contains an adjustable optical system consisting of prisms 22, 23, 24 and lenses 25, 26, the lens 25 being rigidly connected to the prism 22 by a tube 50. A bearing 27 carried by the tube 50 supports a pivot 28 which is articulated to another pivot 31 slidable within the image-space guide 30 which is rigidly connected to the object-space guide 32 and is universally mounted in bearings 33, 34. Rotation of the guide in the bearing 33 causes rotation of the arm 21 about the axis 20, and rotation in the bearing 34 causes the tube 50 to slide within the arm 21. The optical system images each point on the photograph in the plane of a mark 35, the rays being parallel between the lenses 25, 26 so that sliding movement of the tube 50 does not displace the image plane. The lens 26 is mounted in a slide with another lens 36 so that by displacing the slide the lens 36 can be inserted in the system instead of the lens 26 to change the magnification. The plates are illuminated from above. The rays from the marks 35 are deflected by the mirrors 19 along the axis A--A and they are then further deflected into an eyepiece tube.

Title: Improvements in the machining of irregular surfaces
IPC: B23Q35/10
Filed: 1941-05-07
Abstract: 567,745. Lathes. BAUMANN, K., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 7, 1941, No. 5946. [Class 83 (iii)] Irregular surfaces extending mainly transversely to the axis are machined by copying mechanism, wherein a rotating cam or former imparts radial movement to a follower linked to or co-ordinated with a second follower to impart substantially axial movement to a tool or workpiece co-operating with rotating work or tool respectively. In a simple form, the work 2, Fig. 1, having an irregular surface 2b to be machined is carried by a holder 1a on a mandrel driven by the lathe and carrying a cam or former 10. A bell-crank 14 having a fixed pivot 15 has one roller 12 engaging the cam 10 and a second roller 13 engaging a surface 11 on the top slide 7 carrying the tool 3. The slide 7 is carried by a surfacing slide 8 biassed towards the roller 13, on ways carried by the saddle 4, by a spring 9. To enable a series of cuts to be taken, the bell-crank may have the inclination between its arms raised and the pivot 15 is carried by the saddle 4. The cam 10, Fig. 8, has a cylindrical portion leading into an arcuate portion and a tangential portion 10a and is so shaped that in the position where the maximum throw is under the roller 12, movement of the pivot 15 to the left in Fig. 7 causes a displacement of the roller 13 to the right sufficient to move the slide 8 to cancel out the movement of the saddle so that the tool 3 has no movement parallel to the axis. This enables a series of cuts to be taken as indicated by the dotted lines in Fig. 9, all terminating at the point 101. In a modification, the lever 14, Fig. 10, is fitted with a stop surface engaging an abutment 17 under the control of a biassing spring 16. The abutment for the roller 13 is also of cam formation. In further modifications, the cam 10 has its operative surface in a groove on one side instead of on the periphery; the bell-crank carried by the saddle is linked to the top slide 7 ; the spring-biassed slide 8 is omitted and the bell crank is inturned so that the roller 13 bears against a collar on the mandrel which is spring-biassed with respect to the cam 10. In a further modification, the lever has a fixed fulcrum 15 and the cam 10 and work 2 move axially together with the mandrel which is spring biassed at 1a with respect to the chuck. The tool slide 7 carries a cam abutment 11. In further modifications, the work is carried on the slide 7 and the tool by the mandrel ; a second bell-crank and cam 10 are arranged on the other side of the work and tool, and the tool slide is biassed so that first the surface 2b, Fig. 10, may be turned, then the surface 2a, and finally the surface 2c. During turning of the surface 2a, both cams and bell-crank are inoperative. Specifications 567,744, 567,746, 567,747 and 567,748 are referred to.

Title: Process for separating suga
Inventor: STARK JOHN BENJAMIN
IPC: C13B35/06
Filed: 1965-02-11
Abstract: A process for separating the components of a solution comprising sucrose and other sugars (e.g. glucose and fructose) and optionally non sugars (e.g. organic acids) comprises applying the solution to an anionic or cationic exchange resin, (examples given), immediately diluting with water and collecting the effluent in fractions. The fractions which have a ratio by weight of sucrose to other components which is greater than the ratio in the initial solutions are worked up to give sucrose and the other fractions are worked up to give the other sugars and/or non sugars.  The separation may be carried out at an elevated temperature and under pressure.  The process may be used to separate sucrose from cane or beet juice or intermediate or final molasses which has been diluted with water or with fractions from a previous separation, the fractions having a decreased ratio of sucrose to other components with respect to the ratio in the initial solution of the previous separation.
