Abstract: 146,466. Zeiss, C., [Firm of]. Jan. 29, 1919, [Convention date]. Stereoscopic apparatus.-Relates to apparatus for copying from a photostereogram a surface of spatial form, the device including a copying system containing a member movable in any desired direction and guided so as to remain parallel to itself, the copying tool being caused to participate in the movements of the said member in at least one plane. The invention principally comprises means whereby such apparatus is adapted to copy correctly from photograms produced by a stereoscopic camera, the optical axis of which have occupied any given positions in relation to the horizontal and to each other. The copying system comprises a binocular double telescope b mounted so as to be rotatable about the horizontal axis Y-Y in a bracket a<2> which is mounted so as to be rotatable about the horizontal axis X-X in a standard a<1> secured to the base-plate a. Each single telescope includes a train of reflecting prisms b<3>-b<6> of which the prisms b<6> are rotatable about the vertical axes Z-Z, and the prisms b<3> are provided with sighting-marks b<7>. The system of copying-slides comprises a height slide A<1> mounted on a breadth-slide B<1> which is mounted on the depth-slide C<1> displaceable over the baseplate a. The slide A<1> carries a. copying- tool c<2> in proximity to the fixed copy-holder c<3>. Handles d are provided by which the slide system can be manually operated, and clamping-screws d<1>, d<2>, d<3> serve for securing the various slides when required. Mounted on the telescope b so as to be rotatable about vertical axes U-U are two links e<1>, e<2>, which are connected by universal joints f<1> to a plate g, which is mounted so as to be rotatable about the axis V-V on the slide A<1>, the link e<1> being connected directly while the link e<2> is connected to an intermediate member h which can be adjusted in the breadth direction on the plate g. The axes U, Z are connected by belts i<3> providing a gear ratio of ¢ so that the sighting line, determined by the position of the prism b<6>, remains parallel to the corresponding link. The means for setting up the photograms comprise two standards k, adjustable in the breadth-direction, within which are verticallyadjustable pillars l carrying forks m which are rotatable around the vertical axis W-W. Mounted in the forks m so as to be rotatable about the horizontal axes R-R are casings n carrying objectives n<3>. Also carried by the casings n are frames o which are adiustable around horizontal axes and carry the photograms. The various parts of the apparatus are set in positions corresponding to those of the optical axes of the camera used for producing the photograms, and the slide p is adjusted over the slide g according to the scale to which the copy is to be produced.

Abstract: 1,017,251. Continuity testing. STANDARD TELEPHONES & CABLES Ltd. May 10,1963 [May 16, 1962], No.18889/62. Heading G1U. [Also in Division H3] An electrical continuity tester includes a transistor oscillator, which may be a free running multivibrator incorporating the transistors VT2 and VT3, normally biased to a quiescent condition, a transistor amplifier VT1 whose conducting or non conducting condition maintains the multivibrator in its quiescent or active condition respectively and a test input to the amplifier across which the circuit to be tested is connected. The arrangement is such that when a low resistance exists at the test input the transistor VT1 stops conducting so that the multivibrator is activated to actuate an indicating device which may be a loud speaker LS. The frequency of the multivibrator may be adjusted by altering the values of its capacitor cross couplings so that audible tones characteristic of particular tests may be obtained.

Filed: 1969-04-14
Abstract: 1284743 Gas turbine engine combustion equipment GENERAL ELECTRIC CO 14 April 1969 [17 April 1968] 19087/69 Heading F1L A gas turbine engine has, within the outer duct of a combustion region, a cylindrical liner defining a coolant passageway between the duct and the exterior of the liner, which liner has a plurality of circumferential corrugations with slots located at the radially inward peak of each corrugation to direct cooling air from the coolant passageway along the interior surface of the liner. As shown in Fig.2, the augmentor duct 42 of a turbo-fan engine is shielded from the hot augmentor gases by a liner 38 cooled by a portion of the engine bypass air which flows through a passageway 40 between the liner 38 and the duct 42. A mixer 36 of serpentine cross-sectional shape provides circumferentially spaced inlets alternately communicating with the cold by-pass air and the hot turbine exhaust gases so that the flow exiting from the mixer 36 has alternate regions of cold and hot gases to provide substantial mixing in a short axial distance. Circumferentially located about each radially inward corrugation peak 38a are a plurality of slots 44, Fig.4, a portion of the cooling air flowing through the passageway 40 being directed through the slots 44 to provide a cool boundary layer along the interior surface of the liner 38. The liner 38 is formed from a plurality of annular sections having the desired corrugated shape with corrugated strips 46 between the overlapping portions of the sections. Each strip 46 is a metal strip having its corrugations alternately attached to the exterior and interior surfaces of adjacant liner sections. The ratio of the pitch to the depth of the liner corrugations is in the range 40:1 to 10:1. A liner of this construction will resist buckling stresses caused by severe circumferential temperature gradients, is self-supporting and is sufficiently cooled on both its interior and exterior surfaces to eliminate failure due to overheating.

Abstract: 205,189. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). July 12, 1922. Stationary - cutter apparatus for trimming the " overflow " or fin from articles such as moulded rubber heels, and of the type wherein two shear cutters are located one above the other in proximity to an angularly adjustable work table has, according to the invention, means for giving a vertical displacement to one end of the axis of the work table, and also provides a guard for each disc cutter. A small disc cutter 13, Fig. 2, is mounted on a driving shaft 11 and revolves beneath a hollow conical guard 73 so mounted on an adjustable arm 81 as to be able to revolve idly in one direction under the control of a pawl 85. Geared to the driving shaft is another shaft 17 carrying the lower cutter 15, which is of larger diameter but revolves with the same peripheral speed as the smaller cutter. A rotary guard and feed member, in the form of a small wheel 93, is situated a little above the lower cutter and in advance of the point of engagement of the cutters with the work, the wheel being frictionally driven by discs 95, 98 geared to the lower cutter shaft. Lubricant from a receptacle 107, mounted on the machine, is led to the upper guard through a pipe 105. The work table is angularly tilted by a treadle through an arm 69 and turns about two ball-ended pivot screws, one of which is stationary while the other is capable of being moved vertically against the action of a spring 45 by means of a second treadle connected to a lever arm 51. The movements and shape of the work table render it particularly suitable for use with " concavo-convex " rubber heels. In a modification, the upper hollow guard 125, Fig. 7, is geared to the driving-shaft 143 while the lower guard 127 is a stationary member adjustably mounted on the machine frame. The work table has the same treadle-actuated movements, and to facilitate the feeding of the work a slot is cut in the table through which projects a series of idle rollers 159.
