Patent SE-340219-B (SE)
Inventor: KOEBER H
IPC: G01D5/26
Filed: 1969-06-05
Abstract: 1,218,696. Automatic focusing arrangements. BELL & HOWELL CO. May 28, 1969 [June 7, 1968], No.27022/69. Heading G2A. In a camera in which the focal distance is determined and controlled automatically by the angle between a freely hanging pendulous member 36 and the optical axis of the camera, means are provided for blocking the movement of member 36 so that the camera can be focused manually. As shown, the member 36 hangs freely from an axle 38 supported in a plate 40. The adjustment from "auto" to "manual" operation is made by turning a disc (82) Fig. 1 (not shown) so that an index mark (98) thereon points to either of two indicator marks (87; 88). The disc (82) carries a stud 90 which moves in a cut-out area 92 of member 36, and also in a notch 94 cut out of plate 40. The lens assembly 18 rotates in a screw-threaded mounting so that such rotation causes it to move axially. Within the assembly 18 is an annular member 28 having a rearwardly facing ledge 28a, and carrying a pin 30. A spacer member 50 is fixed to acarrier 54 pivoted on a shaft 56. Carrier 54 is urged clockwise by a spring 58, so that spacer member 50 is engaged against a cam edge 44 of member 36 and locks it in any position it has assumed. When the setting disc (82) is rotated to "auto", the stud 90, as shown in its solid line position, engages with the right-hand edge of notch 94. Spacer 50 is moved free of member 36 by manually rotating the lens assembly so that pin 30 moves downwards as seen in Fig. 4. This causes it to engage against an inclined surface 59 of a leg portion 60 at the lower end of carrier 54, so pivoting it anticlockwise against the spring 58, and thus bringing spacer 50 away from cam surface 44. Member 36 is now free to swing as the camera is inclined to sight it at the base of the subject to be photographed, as shown in broken lines in Fig. 3, the stud 90 occupying the position shown in broken line. The lens is now focused by turning the lens barrel so that pin 30 moves upwards Fig. 4, thus freeing carrier 54 and allowing spring 58 to urge spacer 50 against cam 44. The focal distance can be read off by indicia 68 on the barrel which are visible through a window 66 against an index mark 70 When the setting disc (82) is rotated to "manual", stud 90 is caused to engage the left-hand edge of both cut-out 92 and notch 94. Thus when the camera is oriented by inclining the optical axis downwards, member 36 is blocked against rotation. The lens assembly may now be focused by hand, by rotating it until any desired indicia 68 is aligned with the index mark 70.

Inventor: KORTHAUER H
IPC: C06B21/00
Filed: 1987-08-28
Abstract: The known presses for compressing a powdery material, in particular for compressing powdery explosives in the manufacture of detonators for the ignition of explosive charges, take the form of expensive, heavy and complicated devices in which single pressing with weights is employed and therefore large masses need to be moved. To reduce this expenditure and to achieve an accurate, rapid-working light-weight press, the latter is designed with a guide system consisting of two mutually parallel guide columns which are rigidly interconnected at their upper and lower ends by a cross-member in each case and on which a tool holder which bears the hydraulically actuable pressing member is mounted displaceably, the lower cross-member having a pressure piece serving as abutment and the upper cross-member having a cylinder subjected to auxiliary force for limiting the pressing force.

Title: Jet divider device for filling heads
Inventor: GRAFFIN ANDRE JEAN-JACQUES
IPC: B67C3/22
Filed: 1984-05-29
Abstract: In a preferred embodiment the jet divider device according to the invention comprises a series of frustoconical walls (2) having at the top a collar (3) projecting radially outwards, three radial arms (4) extending inwards and effecting the spacing of the members when a plurality of members of decreasing diameter are nested. The assembly is disposed in a grid-carrier sleeve of a filling head and produces a radial component of the flow. During the flowing of a pulpy product, the elements of the pulp which would tend to straddle the top edges of the different members are thus subjected to a radial force and entrained by the liquid to be packed.

Title: A sizing composition,a method for the preparation thereof and a method of use
Inventor: BLIXT TONY
IPC: D21H21/14
Filed: 1989-06-15
Abstract: The present invention relates to a novel sizing composition in the form of an aqueous emulsion comprising a hydrophobic cellulose reactive sizing agent and a cationic polymer comprising a starch, the novel features of said composition being that the starch possesses a combination of (A) a branched, high molecular weight structure as reflected by an amylopectin content of at least 85% and (B) a degree of substitution of about 0.05 to 0.40. Such sizing compositions can be prepared by dissolving the aforementioned starch in water, adjusting the temperature to above the melting point of the sizing agent and adding the sizing agent to the solution so as to form a coarse emulsion , which is subsequently subjected to shear forces to reduce the particle size of the emulsion. The invention also relates to a method of preparing sized paper or paperboard by using the above-mentioned sizing composition. Also, the invention relates to the sized paper for paperboard prepared by said method. Such paper products show reduction in liquid absorbency as compared to products using conventional sizing agents, reduced consumption of optical highteners, and enhanced development of sizing.

Abstract: With certain picture formats, for example, presentation of 16:9 picture on a 4:3 screen, the cut off signals for the dark radiation current regulation inserted into the video signal can become visible in the black bands. The task is to avoid such signals becoming visible on the screen. The measuring process for the cut off regulation only happens briefly, for example, always only shortly after switching on the receiver. The result of the measurement (Uco) is stored in a memory (14) and read out from the memory (14) during most of the operating time. In particular, color televison receivers for the presentation of differing picture formats.

Abstract: The present invention describes biologically compatible inert perfluorocarbon liquids capable of removing carcinogens from cells and thereby reducing the risk of cancerous cell transformation. This invention can be used to reduce the build-up of carcinogens, and thus be used as prophylactic medicaments in reducing the risk of chemically induced cancerous cell transformation and thus cancer. These liquids can be used as medicaments applied to any organ of the body; such an application would reduce the build-up of carcinogenic chemicals within cells of that organ and as such can be used to reduce the risk of a variety of cancers produced through chemical carcinogenesis. Such cancers include lung cancer, stomach cancer, rectal cancer, and certain types of skin cancer.
