Abstract: 935,519. Transmission testing; frequency analysis. SIEMENS & HALSKE A.G. April 4, 1961 [March 31, 1960], No. 12036/61. Drawings to Specification. Class 37. [Also in Groups XXXIX and XL (c)] For testing the amplifiers along a line, a plurality of test frequencies are sent simultaneously and the amplitude of an odd order intermodulation product is measured. In a preferred embodiment two test frequencies f 1  and f 2  are used and the amplitude of the third order intermodulation product 2f 1 -f 2  is measured. To enable a narrow band to be selected despite possible fluctuations in f 1  and f 2  a current of frequency 2f 1 -f 2 +f is derived from the received frequencies f 1 , f 2  and a local source f. This current is beaten with the received intermodulation product 2f 1 -f 2  (received through a relatively broad band filter) to produce a frequency f which is passed through a narrow band-pass filter to a measuring device.

Title: Improvements in or relating to photographic or kinematographic cameras
Inventor: NAGEL HUGO
IPC: G03B19/04
Filed: 1951-05-28
Abstract: 696,521. Photographic and kinematographic cameras. KODAK, Ltd. May 21, 1952 [May 28, 1951], No. 12462/51. Classes 97 (i) and 98 (i). In a photographic or kinematographic camera of the type in which a closure wall for the body. is hinged at one edge and latched to the body at the opposite edge, the latching edge of the wall carries a projection for co-operation with a cam slot in a slidable latch member on the body such that when the wall is moved to the closed position the projection moves the slidable member towards a latching position and upon manual movement of the slidable member in the opposite direction the cam slot acts on the projection so as to open the closure wall partially. As shown, a latch bar 8 is slidable within a channel-sectioned housing 12 which is fixed to the end wall of the camera by rivets 13 and spacing blocks 14. One end 17 of bar 8 is upturned and projects through a slot 19 in housing 12. The other end 27 is springy and bent slightly upward. When the bar is moved to the right as in Fig. 3 its end 27 moves under a V-shaped depression 29 in the housing wall and is held by frictional engagement therewith. This is the unlatched position. When the hinged camera wall is closed, a pin 26 on its latching edge passes through a slot in housing 12 and enters a cam slot 25 in bar 8 which is thereby moved to the left. The end 27 of bar 8 engages the sloping side 31 of depression 29 and completes the movement of the bar to the left into the latched position. The action of end 27 on depression 29 then prevents unintentional movement of the bar to the right. To open the camera, bar 8 is moved to the right by means of the projection 17. The action of slot 25 on pin 26 moves the wall slightly, so that its edge may be gripped to pull it open. The housing 12 may have rolled-over ends 15 for attachment of a carrying handle 16.

Title: Improvements in milling cutters

Filed: 1926-05-17
Abstract: 256,905. Krupp Akt.-Ges., F. Jan. 30, 1926, [Convention date]. Addition. to 255,399. Milling-cutters. - In a milling-cutter as described in the parent Specification, the rearrangement of the teeth to bring either the left-hand or right-hand teeth into continuous helical alignment is effected by adjusting the angular positions of the discs. Fig. 1 shows one position of the discs A - - F wherein the right-hand teeth a<3> form continuous helices while the left hand teeth a<4> lie along stepped helices and the grooves a<1> - - #<1> of the respective discs engage the key in the cutter body. In order to effect the rearrangement shown in Fig. 3 the discs B - - F are respectively provided with grooves b<2> - - #<2> which are engaged with the key. This readjustment, however, disturbs the continuity of the worm thread and in order to compensate for this, suitable spacing discs G are located between the discs. This adjustment is employed for making or grinding the faces of the teeth a<4>. In use the cutter is assembled as shown in Fig. 1. In a modification, the use of spacing discs may be dispensed with. In this case the worm is triple threaded as shown in Fig. 5. In the normal position the right handed teeth h<4>, i<4>, k<4>, are in helical alignment but by angular adjustment of the discs J, K as shown in the Figure through 120‹ and 240‹ respectively, the teeth h<5>, i<5>, k<5>, are brought into alignment without disturbing the continuity of the threads. This method may also be used for other multiple-threaded worms, the angular adjustment of the discs being a multiple of the angle W<1> between the threads. The invention is also applicable to conical cutters.

The vertical adjustment of the table allows of varying the scale of backgrounds formed by back projection from a fixed projector below the table on to a ground glass or like screen which is substituted for the opaque table top. In the apparatus shown, the table and camera are adjusted in height by cables operated by winches 23, 27 respectively, the latter'having a fine-adjustment means 61. The camera is driven by a synchronous motor 16 through a known type of clutch box 17 which may be set for different manners of exposing the film. The object-supporting table shown comprises a top 57 movable on cross-slides by hand wheels 54, 55. A member carrying a turntable may rest upon or replace the top 57, the turntable carrying a table member which can be traversed across it and means for separately traversing a model. The automatic focusing'mechanism shown in Fig. 2 comprises a counterweighted chain 31 secured to the table 14 and passing over a sprocket on a screwed shaft 36 mounted on the camera frame 15. Adjustment in height of either table or camera causes rotation of the shaft, which adjusts through a slide block 38, link 39, pivoted arm 40, cam 43, and pivoted arm 44, an arm 47 projecting from the lens mount 48.

Abstract: Polyvinyl chloride, polyvinyl acetate, vinyl chloride-vinyl acetate copolymers, butadiene acrylonitrile copolymers, or polychloroprene are rendered porous by suspending fine particles of the polymeric material in a non-solvent fluid, adding fine particles of a leachable substance to the suspension in sufficient quantity to form a paste, drying the paste, and leaching out the leachable substance.  In examples, a microporous product is obtained by suspending a vinyl chloride-vinyl acetate copolymer in either a mixture of xylol with diisobutyl ketone or tri-2-ethyl hexyl phosphate and then adding sodium nitrate, drying the mixture, consolidating by heat and then leaching out by running water; or polychloroprene in latex form is mixed with dextrose and after drying and heating to vulcanize the polymer, the dextrose is removed with running hot water.
