Title: Improvements in or relating to a clamping device for an angularly adjustable member
IPC: F16M11/12
Filed: 1948-01-12
Abstract: 640,309. Hinges. KODAK, Ltd. Jan. 12, 1948, No. 926. Convention date, Jan. 30, 1947. [Class 65(ii)] In clamping means for an angularly-adjustable member of the type comprising a cylindrical bearing member supporting the adjustable member and formed with clamping means movable into engagement with the adjustable member to hold it in adjusted position, the bearing member is provided with a pair of axially spaced slots extending round the major portion of its circumference and connected by an axial slot to form a pair of resilient circumferential fingers which are urged outwards by means disposed in the axial slot. The embodiment shown consists of two similar pivotal joints forming a universal mounting e.g., for a camera on a tripod, and comprises an attachment plate 13 with a lug fitting between the limbs of a forked intermediate member which has a part 54 fitting between a pair of lugs 16 on a baseplate 14. In each joint the three parts are bored to receive a cylindrical bearing member 18 which is fixed to the two outer parts by screws 52 and is divided over most of its circumference at two planes 24 spaced apart by less than the width of the central part 54 of the joint, so that the latter bears on parts of the member 18 outside the divisions 24. The middle portion of the member 18 is cut at 25 to divide it into two resilient fingers and to form a slot to receive the end of a bar 32 which, when tilted, presses the fingers outwards into clamping engagement with the middle part 54 of the joint; the other end of the bar is guided in a slot 39 in the member 18, and the bar is tilted, against the action of a wire spring 35, passing through a hole in the bar and lying in a groove inside the member 18, by a cam 50 on a spindle which bears in check-plates 19 closing the joint and carries an operating knob 49.

Title: Multi-stage conical evaporator
IPC: B01D1/30
Filed: 1962-02-19
Abstract: 987,124. Heat exchange elements. SEPARATOR A.B. Feb. 19, 1962 [March 15, 1961], No. 994/63. Divided out of 987,121. Heading F4S. An evaporator is made up of a series of heatexchangers mounted, one above the other, in a common housing, each heat-exchanger comprising a nest of heat-conducting, truncated cones 14 spaced apart to form channels, and the design being such that each heat-exchanger has two sets of channels, the channels of each set being connected in parallel and alternating with the channels of the other set. In the evaporator shown, there are three heatexchangers, separated by partitions 45 and 46, arranged in a housing in such a manner that four separate chambers 3a, 2a, 2b and 2c are provided, which together with the heatexchangers form a multiple-effect evaporator. The upper end of a set of channels of the first (i.e. lowest) heat - exchanger communicates, via chamber 2a, chamber 50, and hole 8b, with a set of channels of the second heatexchanger; and the other set of channels of this second heat-exchanger communicate, via chamber 2b, chamber 49, and hole 8c, with a set of channels of the third heat-exchanger. The apparatus is clamped together by bolt 36a and nuts 38a, 38b. The bolt has three recesses 43a, 43b and 43c, which communicate, via passages 44a, 44b and 44c, with a set of channels of the first, second and third heat-exchangers, respectively. The liquid-to-be-evaporated is introduced into one set of channels of the first heat-exchanger through recess 43a; and the other set of channels is supplied with steam via inlet 4a, chamber 3a, and hole 8a. A mixture of liquid and vapour flows out of the top of the first heat-exchanger into chamber 2a. The liquid, which separates out from the vapour, is withdrawn through outlet 7a, and is introduced via recess 43b into one set of channels of the second heat-exchanger, while the vapour passes to the other set of channels of this second heatexchanger, wherein it constitutes the heating- medium. The mixture of liquid and vapour discharged from the second heat-exchanger is separated in chamber 2b. The liquid is further evaporated in the third heat-exchanger, the latter being heated by the vapour from chamber 2b. The final concentrated liquid product is withdrawn from the apparatus through outlet 7c, and the vapours leave through outlet 6c. Steam-condensate is discharged through outlet 42a. The condensates, which form in the second and third heat-exchangers, collect in chambers 47 and 48, respectively, and are discharged via outlets 42b and 42c. In order to maintain boiling, the pressure of the liquid being evaporated in the second evaporator must be lower than that of the liquid in the first evaporator, and the pressure in the third evaporator must be less than that in the second. Alternatively, fresh steam may be introduced into the steam-inlets of each stage. Specification 987,122 also is referred to.

Abstract: PURPOSE:To expand the diameter of a spiral pipe easily by increasing the detaching speed of a wire rod detached from a spiral pipe when driving force given to a beltlike body reaches a preset ceiling value when the diameter of the spiral pipe is expanded. CONSTITUTION:Driving force is given to a beltlike body 10 by driving a hydraulic motor 22 while the ceiling value of oil pressure is set properly, the diameter expansion work of a spiral pipe is started and a beltlike wire rod 30 is wound by a winder 50. When oil pressure in the hydraulic motor 22 reaches a preset ceiling value, the take-up speed of the beltlike wire rod 30 by the winder 50 is increased for a fixed time, and the axial length L of a truncated cone section, a diameter of which is expanded successively, in the spiral pipe is lengthened. Said ceiling value of oil pressure can be set in such a manner that oil pressure in the hydraulic motor 22 is measured and levelled at every fixed time immediately after the diameter is expanded and a maximum value at a time when the difference of the maximum value and the minimum value exceeds hydraulic control width is used as the ceiling value.

Abstract: PURPOSE:To enhance an image sensor in resolution independent of the width of a common electrode by a method wherein either a discrete electrode of a common electrode between an input image picture and an organic photoconductive layer is formed in a multilayered structure, and a part of the electrode confronting the other electrode is formed in a mono-layered transparent structure. CONSTITUTION:A block layer 7 and a photoconductive layer 8 are formed on a support 6 on which discrete electrodes 5 are provided, and furthermore a common electrode 9 is provided thereon. A part of discrete electrode 5 is formed in a two-layered structure composed of a transparent electrode and an optical shielding film, and a part of the electrode 5 confronting the common electrode 9 is partially formed into a mono- layered structure or an opening 11 where the optical shielding film is removed and only a transparent electrode is present. When image picture data are inputted through the common electrode 9, a part of the common electrode 9 is formed in a two-layered structure 10 composed of a transparent electrode and an optical shielding film, and a part of the common electrode 9 confronting the discrete electrodes 5 is formed into an opening 11 by removing an optical shielding film. By this setup, an image sensor practically high in resolution can be obtained.

IPC: H01F41/04
Filed: 1984-01-07
Abstract: PURPOSE:To obtain super-miniature and high precision transformer with simplified facilities by uniformly forming a thin conductive metal layer at the circumference of a round bar type magnetic core and leaving said conductive metal layer on two or more spiral lines which are separated under the non-contact condition without crossing by a fine trimming apparatus. CONSTITUTION:The entire part of external circumference of a round bar type magnetic core 11 made of ferrite, silicon steel, nickel steel or permalloy is coated with an insulating paint 12 and a thin metal layer 13 such as copper is deposited on such paint. Total of three laser trimming apparatuses 3a-3c are arranged at a time with inclination so that the interval between the laser beams 4a-4c emitted to the one side of magnetic core 11 becomes the prescribed interval at the surface of magnetic core 11. While the beams 4a-4c are irradiated, the magnetic core 11 is rotated at a constant number of rotations and is moved in the one direction at a constant speed. Thereby, the beams 4a-4c draw the spiral loci, thus eliminating the fused layer 13 of this part and exposing the layer 12 under said layer 13.
