Title: Improvements in or relating to optical systems for the production of complemental color images for color photography
IPC: G02B27/14
Filed: 1923-03-26
Abstract: 212,134. Kalmus, Comstock, & Wescott, Inc., and Comstock, D. F. March 26, 1923. Optical systems.-For the production of two or three separate complemental images in the same plane, optical systems are provided by which a beam of light is divided into similar divisions and renected in the same general direction along substantially equivalent optical paths to the focal plane. The images thus formed are similarly orientated. In the production of two images of the object 0, Fig. 1, on the film F, a lens L and a series of compound prisms P, P' are utilized. The rays entering the prism P are normal to the surface x' a.nd meet the semi-transparent reflecting surface x part being reflected towards the surface x<1> and from thence to the film F to form the image M, and the other part transmitted through the prisms P<11>, P<1> to the totally reflecting surface y and thence parallel to the direction of the first part of the ray in the prism P to the surface y<1>, by which it is reflected to form the image N on the film. This arrangement of prisms gives images similarly arranged and with ray paths of the same geometrical length. Fig. 2 shows the addition of a third prism forming an additional image O<1> in substantially the same manner as the arrangement shown in Fig. 1. In a modification, Fig. 3, three images are formed by right-angled prisms and reflectors. The rays passing through the lens L are partially reflected from the mirrors c, d to the prisms C, D respectively, disposed at an angle of 45‹ to the film F. By reflection at the surfaces of the prisms C, D images M, N are formed. The unreflected portion of the rays meets the prism E and is reflected therefrom to the mirror r and thence to the film to form the third image O<1>.

Title: A steam-generating installation including a forced-flow once-through boiler
IPC: F22B29/10
Filed: 1960-03-11
Abstract: 943,020. Forced-flow steam boilers. SIEMENS-SCHUCKERTWERKE A.G. March 11, 1960 [March 12, 1959], No. 8737/60. Heading F4A. In a once through boiler of a unit power plant comprising an economiser 2, evaporation stages 3, 4 and a superheater 5, temporary deficiency and excess of water in the stages 3, 4 on sudden increase and decrease of load is offset by increasing or decreasing the rate of water injection between the stages. A feed pump 1 supplies water to the economiser 2 through a valve 8 which is set by a controller 6 in response to load as measured at an orifice 7 so that under steady load conditions about 85% of the total feed enters the economiser. Of the remaining 15% of feed water, about 5% is injected before the superheater to control the final steam temperature whilst 10% is injected at a point 9 where the steam content of the working medium is from 50 to 80%. The injection rate at 9 is controlled by a valve 11 which is adjusted by a controller 10 according to load as measured at the orifice 7. At steady loads the controller keeps the rate of injection at a constant percentage of the steam output. If the load suddenly increases the controller 10 effects a rapid increase in the injection rate to offset the deficiency of water in the zone 4, a timing ele ment causing the increased injection rate gradu ally to be cancelled out until the boiler control system has become adjusted to the new load. A sudden decrease in load effects a rapid decrease in the water injection rate to offset the excess of water in the zone 4. Follow-up control signals for the controllers 6, 10 are obtained from flow measuring orifices 20, 21 in the main feed and injection lines respectively.

Title: A new or improved inking mechanism for printing machines
IPC: B41F31/08
Filed: 1935-03-21
Abstract: 454,157. Revolving cylinder pumps. HOE & CO., Ltd., R., 109, Borough Road, London.-(Assignees of Buckingham, E. ; Belmont, Massachusetts, U.S.A.) March 21, 1935, No. 8877. Convention date, March 21, 1934. [Class 102 (i)] [See also Group XVI] An inking-mechanism for a printing-machine comprises a pump provided for each conduit 33, Fig. 3, and the pumps which are prac. tically identical in con struction are mountec in pairs back to back upon the supporting plate 37 in two lines so that four lines of pump outlet pipes are provided to register with the conduits 33. The pumps are locked on the plate 37 by the dovetail slot 40 therein and a clamping block 88 being suitably shaped to co-operate therewith. Each pump has front and back plates between which is situated a two piece plate structure 51, 52, Fig. 7, which is arranged to form inlet and outlet ports 53, 54, all the plates being shaped at 50 to co-operate with the holding means. The pump rotor 55 has two diametrically opposed slots 59, 61 on one of its faces, leaving four pads 62 extending into the area embraced by the plates 51, 52 and these plates are in running engagement with the rotor at the surfaces 64, 65. Two plunger blocks 66, 67 having rectangular openings 68, 69 and transverse slots 71, 72, respectively are assembled with their slotted faces abutting within the slotted rotor face and a rectangular sleeve 73 positioned within the openings 68, 69 has a pin 74 secured thereto which is rotatably mounted within a vertically adjustable bar 75 and is normally eccentric to the rotor 55. A gear 76 is fixed to the rotor 55 so that as the gear is driven the rotor turns in the direction of the arrow and the plunger blocks 66, 67 reciprocate, so that four pumping strokes are given during each revolution, resulting in a steady flow of ink. The position of the eccentric sleeve 73 may be adjusted by a manually-operated nut 79 which screws on to the end of a screw 78 adjustably mounted in the top plate of the reservoir 21 and connected by linkage 83 to the rod 75 so that downward movement of the screw serves to raise the sleeve, and by this means all the pumps may be individually adjusted to vary the amount of ink discharged. All the gears 76 are given a common drive by gears 91 on a common driven shaft 92 positioned between the two rows of pump assemblies so that one gear drives the gears 76 of four pumps, on account of the back to back and side by side arrangement. The shaft 92 is driven in timed relation to the machine and, in order to prevent flow of ink in the reverse direction for certain of the pumps due to the fact that the rotors move in the opposite direction, the axis of the eccentrically positioned sleeve 73 which operates each reversed pump is arranged above the axis of the rotor, the linkage 83 for adjusting the position of the sleeve being suitably modified. Specification 126,815, [Class 100 (ii)], is referred to.

Abstract: 568,922. Tractor-trailing couplings. SIMMONS, L. R. June 9, 1943, No. 9265. [Class 103 (v)] In a hauling unit including a first vehicle such as a tractor connected by a draft member 45 to a second vehicle such as a trailer, the draft member 45 being pivotally connected to the two vehicles, means are connected between the vehicles for raising either vehicle with respect to the other for transferring part of the weight of the raised vehicle to the other vehicle. In the construction shown the means for raising the vehicle comprises a hydraulic cylinder 51 connected at 43 to a hitch member 39 secured to the front axle assembly 28 of the trailer vehicle, the assembly being carried by the trailer frame 24. The piston rod 54 of the hydraulic cylinder is pivoted at 56 to the draft member 45, which is pivoted at 41 to the hitch member 39. When the piston 53, Fig. 3, is forced down in the cylinder 51 by hydraulic pressure, applied on operation of a handle 21, the triangle 41, 43, 56 is distorted and the parts assume the position shown in Fig. 4, the front wheel 36 of the tractor front axle assembly 28 being lifted up together with the trailer frame 24 thus transferring part of the trailer weight to the tractor through the front pivot of the draft member ; if the piston 53 is forced up in the cylinder the resultant distortion of the triangle 41, 43, 56 causes lifting of the front end of the draft member 45 to lift the tractor rear wheels, weight being transferred to the trailer wheels. The hydraulic pressure may be supplied by the gear-wheel pump 20. An adjustable member 65 may be used to lock the draft member 45 in the position to which it has been adjusted by the hydraulic pressure. Modifications of the hydraulic cylinder and its connecting parts are described.
