Filed: 1956-04-26
Abstract: 806,318. Ditch-cleaning apparatus. CARTER BROS. (BILLINGSHURST) Ltd., and KILLNER, L. S. July 24, 1957 [April 26, 1956], No. 12855/56. Class 68(1) The tractor - mounted, ditch cleaning apparatus of Specification 755,285, which is referred to, is modified by terminating the rope 8 controlling tilting of the scoop 6 at the apex of an inverted V structure 10 instead of at a hand lever. The bottoms of the legs of the V structure are pivotally mounted on the jib of the apparatus or on the tractor. Springs 11 between the structure 10 and the support thereof bias the structure to exert a turning moment on the scoop in opposition to that exerted on the scoop as it it dragged across the bottom of the ditch. Thus the scoop will be rotated to empty on cessation of movement over the bottom unless the load picked up by the scoop exerts sufficient tension on the rope 8 to cause the structure 10 to overcome a spring-biased latch 19 to allow the scoop to tilt backwards to retain the load. Movement of the structure beyond the latch 19 is regulated by removable stops 20, 29.

Abstract: 777,520. Steering vehicles. ACF INDUSTRIES, Inc. May 4, 1955, No. 12913/55. Class 79(5). [Also in Group XXXII] In a two-axled railway car having radius rods 20 connected to the ends of an axle 10, the rods 20 are connected to a coupler 24 whereby the wheels 11 on the axle are maintained tangential to the track rails. As shown the ends of each axle are connected through resilient connections 21 and the rods 20 to pivots 22a on hangers 22. Each axle is suspended from the railway car body U by spring telescopic struts 14 and by a pair of spring cylinders 18. The coupler 24 at each end of the car comprises a coupler head secured to a hollow shank 25 slidable on a tongue 26 pivoted at 23 to the body U. The head is received in a carrier 32 with freedom for vertical movement, the carrier 32 being pivotally connected at its ends to draft links 33 of conventional draft gear 41. Secured to the pivots 22a are links 45 interconnected at their inner ends by levers 46 pivoted at 48 to the body U, whereby pivotal movement of the coupler head about the pivot 23 due to relative movement of the preceding vehicle causes deflection of the axles 10 of the vehicle to maintain the wheels 11 tangential to the rail curve. In a modification, Fig. 2 (not shown), the links 45 and levers 46 are replaced by crossed links.

Title: Drop volume measuring apparatus
IPC: G01N35/10
Filed: 1958-04-24
Abstract: 838,406. Filling tubes with liquids. TECHNICON CHROMATOGRAPHY CORPORATION. April 24, 1958 [May 23, 1957], No. 13107/58. Class 125(2). [Also in Groups XVIII and XL(b)] Apparatus for measuring the volume of a liquid which is collected drop by drop in one or more receptacles is provided with means to measure the individual volume of each drop of the liquid and to integrate said measurements for a plurality of drops of the liquid. In Fig. 1, drops of liquid fall from a chromatography column 11 into a receptacle 86. At the position D1, each drop intercepts a light beam 22 directed on to a photo-tube 26 and produces a pulse which after amplification at 30 is fed to a delay circuit 32 which in turn triggers a driven sweep circuit 40 whereby there is performed a single horizontal sweep in a cathoderay camera tube 42 while the drop is falling through the position D2. The drop is imaged upon the camera tube 42 by means of a light beam 52 and the output of the camera tube produces a pulse having a time duration proportional to the width of the drawings. The output of the camera tube 42 is fed to a time comparison circuit 60 and then to a peak detector stage 66 which produces an output voltage proportional to the width of the drop. The output of the peak detector stage 66 is gated under the control of a further delay circuit 34 triggered by the output of the phototube 26 whereby a pulse of amplitude proportional to the drop width is applied to a cubing amplifier 70 which provides at its output a pulse of amplitude proportional to the volume of the drop. The output of the amplifier 70 is connected across the resistors 90, 92 in parallel with a slide wire potentiometer 94 of a conventional null-type balancing servo system wherein a motor 104 is arranged to drive the slider 98 to a null point, the motor 104 being coupled by a uni-directional coupler 112 to a revolution counter 114. The servo-system is returned to zero after the passage of a drop, under control of a further delay circuit 36 triggered by the output of the photo-tube 26, without operating the revolution counter 114. Thereby the counter 114 integrates the volume of a succession of drops until upon reaching a predetermined count it closes contacts 116, 118 which causes the receptacle 86 to be replaced by another receptacle by means of a step-bystep pin and rack mechanism which drives a carrier for a plurality of the receptacles. Specification 689,079 is referred to.

Abstract: 1,177,278. Holograms. BATTELLE DEVELOPMENT CORP. March 21, 1967 [March 30, 1966], No.13114/67. Heading G2C. A method of producing a three dimensional image comprises the steps of illuminating an object 21 with a first beam 19 of coherent light; positioning a photographic plate 25 to receive light 23 from the object; simultaneously directing a second beam of light 17, coherent with respect to the beam 19, on to the opposite side of the plate to that side receiving the light 23; developing the plate; and reconstructing an image of the object by illuminating the developed plate in reflection with white light. The image will be coloured depending on the colour of the beams 17, 19 and on the selective reflective/filtration characteristics of the developed plates. The colour of the image may be selected by controlling the shrinkage of the emulsion of the plate during development, or by adjusting the angle of incidence of the white light beam on the developed plate, or by adjusting the angles of incidence of the beams 17, 19 on the plate 25. The method may be modified to produce full colour three dimensional images by making the beams 17, 19 combinations of two coherent light beams of different colours.

Abstract: 244,040. Rohrbach, A. Dec. 2, 1924, [Convention date]. Addition to 226,516. Steering.-To prevent aeroplanes from stalling, an auxiliary pivoted plane in the airstream acts upon a device between the control lever and the elevator, instead of acting upon the tail plane or other auxiliary surface as described in the parent Specification, to prevent too steep an inclination from being given to the wings, by movements of the control lever when the angle of inclination to the flight path is already high. The control-lever is connected by cords to a lever H secured to a transverse rock shaft D, and the elevator-cords are connected to the apices K of a linkage V pivoted about the same shaft. The linkage V is connected by rods Z to a block G sliding in a guide B fixed to the shaft D and the block G is moved to deform the linkage V by cords led to the auxiliary plane over pulleys U and over pulleys close to the shaft D. The auxiliary plane may be mounted in the rear edge of a wing. Instead of the linkage described, toothed differential gear or cam gear may be employed. The moving parts are balanced to prevent movements due to accelerations.
