Title: Steering articulated construction vehicles
Inventor: GRANRYD THORVALD GOSTA
IPC: B62D53/02
Filed: 1966-02-11
Abstract: 1,133,021. Steering articulated vehicles. INTERNATIONAL HARVESTER CO. 11 Feb., 1966, No. 6075/66. Heading B7H. In an articulated construction vehicle having front and rear frame sections 12, 14 pivotable about a vertical axis by hydraulic steering rams 48, 49, the wheels on an axle supporting the rear frame section 14 are steered by hydraulic rams 30, 31 supplied in parallel with the rams 48, 49 by a steering control valve 56, and a tie-rod 52 extends between the front frame section 12 and an arm 50 on one steerable wheel to co-ordinate the steering movements. The arm 50 extends inwardly from the pivot axis of the steerable wheel to provide normal steering, but may extend outwardly therefrom to provide "crab-steering" wherein movement of the wheels is opposite to that of the frame sections. The steering control valve 56 is actuated by a steering wheel 54 and follow-up linkage 58 and is supplied with fluid by a pump 92 which is supplemented during low-speed manoeuvres from a pump 96 through a diverter valve 98. The pump 96 normally supplies a control valve 94 controlling actuation of rams 40, 44 which position a bucket mounted on boom arms carried by the front frame section 12. The diverter valve is actuated by fluid pressure communicated through a line 100 from a control valve 88 which is fed by a pump 90 and effects ratio selection in a gear-box 22 coupling an engine 18 to the axles on both frame sections 12, 14.

[Class 78 (iv)] In automatic means for loading vehicles of the kind having a movable compressing panel, the gap between the panel and the vehicle body walls is closed by a metal plate articulated to intermediate pieces attached to the panel. The metal plate 1, Fig. 1, which seals the space between the wall P and the panel 2 is secured to said panel by means of a rubber strip 3 and a curved.plate 4. In a modification, Fig. 8, the plate 24 has a curled portion 30 located in a recess in the panel 25 and holes 28 are provided to permit evacuation of material which may have passed behind the plate 24. Fig. 3 shows a modification in which holes 11, in a V-shaped plate 10, are engaged by tongues 12 carried by a plate 13, a rubber strip 15 being provided to press the plate 10 into contact with the wall 16. In the modification shown in Fig. 5 lugs 18 on a plate 17 are pivoted in brackets 19 secured to the panel 20 which panel has an extension 31 either in front or behind the plate 17. This plate is maintained in contact with the wall 23 either by gravity or by a spring (not shown).

Apparatus for dispensing liquids comprises means 1 for supporting a device 7 for delivering a measured quantity of liquid and a valve 10 controlling supply of a second liquid, a common element 16 having operative connection with the device and the valve and adapted when actuated to cause both liquids to be delivered simultaneously, a pedal 18 linked at 17 to the element 16 to actuate the latter, and stop means 18a for limiting movement of the element 16. In the preferred embodiment the arrangement shown is duplicated, the two valves 10 being served through separate control valves 14 from a common supply pipe 12 and the two pedals being arranged so that they may, if desired, be operated simultaneously by one foot. The link 17 includes a turn buckle 23 and a spring- loaded telescopic connection the upper portion 19 of which by engagement with a platform 2 serves as an additional stop means. A flange 9 on the measuring device engages a spring- loaded arm 15 for operating the valve 10 and is engaged by the element 16 which is centrally pivoted. Forked members 25 shaped to suit the receptacle, such as a paper carton, to be filled are adjustably clamped at 24 to the means 1. The latter or the platform 2 may be mounted on a shop counter, the pedals being mounted in a frame fixed beneath the counter and connected by wire links to the links 17.

Class 97 In photogrammetric plotting apparatus a tracing point is driven in the x and y co-ordinate directions by rotations derived from a variable speed motor at fractions of its speed in the proportions of cosine and sine of an angle defined by the position of an eccentric pivot on a handwheel. Thus the motor speed determines the speed of the tracing point and the setting of the handwheel its direction. In the form shown the links 23x, 23y pivoted to the pin 11 on the handwheel 12 act as resolving linkages to transmit cosine and sine movements to toothed segments 21x, 21y engaging pinions 20x, 20y forming parts of variable speed drive mechanisms having co-axial input and output shafts. The input shafts are driven by belts 16x, 16y from the variable speed motor 1, the outputs being fed by flexible shafts 13x, 13y to leadscrews 14x, 14y which position the tracing point 15.

Title: Photographic camera, preferably a motion picture camera
IPC: G03B7/0993
Filed: 1959-02-24
Abstract: 888,523. Photographic cameras. CONTINA BUREAUX-UND RECHENMASCHINENFABRIK A.G. Feb. 24, 1959 [March 7, 1958], No. 6366/59. Classes 97(1) and 98(1). In a photographic camera provided with at least two lenses mounted thereon and a lightresponsive cell connected to a measuring device, the said lenses are so mounted on one or more holders that each lens can be moved between a position for taking a photograph therethrough and a position in the path of light to the light responsive cell. As shown (Fig. 1), lenses 3 and 4 are mounted on a lens carrier 2 rotatable about a screw 5 so that either of the lenses may be brought to a position in front of a photo-cell 13, or the exposure aperture 11 for the film 8. The pointer 15 of the measuring mechanism shown generally at 14, is visible in the view finder 16, and co-operates with indication marks also visible in the view finder. Diaphragm rings 18, 19 have teeth which intermesh in such a manner that adjustment of either one ring causes the other to move in unison. For obtaining approximately correct exposure value setting of the lens in front of the exposure aperture, the diaphragm of the lens in front of the cell 13 is adjusted until indicator 15 registers with said marks in the view finder. Owing to the different focal length of the lenses, a more correct exposure value setting is obtained if the actual lens to be used for the exposure is first moved in front of the cell 13, and the diaphragm adjusted as before. In modifications, more than two lenses may be arranged on the lens carrier, the lenses may be separately mounted on holders independently slidable or pivotable on the camera front, and the lenses may be exchangeably mounted on the holder or holders. Independent diaphragm mechanisms may be provided.

Abstract: 253,184. Mellor, J. W. March 9, 1925. Pottery materials; enamelling, vitreous. - In the manufacture of pottery by a process in which the body and the glaze are fired at the same time in the glost oven, the composition of the body is adjusted so that it matures at the same temperature as the normal glaze. To adjust the body, fluxes are used as constituents of the mass. For example, in making tiles, a normal body material containing 20 parts of ball clay, 20 parts of china clay, 44 parts of flint, and 16 parts of stone is mixed in the grinding mill with 2“ per cent of a mixture of 1 part of calcium or magnesium borate and two parts of sodium silicate rich in silica. This flux may be added in the same proportion to a mixture of 36 parts of ball clay, 12 parts of china clay, 2 parts of flint, 31 parts of felspar, and 19 parts of stone, to make a body suitable for producing electric insulators and fittings by this process.
