Title: Reflex cameras
IPC: G03B19/12
Filed: 1976-11-03
Abstract: 1511399 View-finders for reflex cameras ZENZA BRONICA INDUSTRIES Inc 3 Nov 1976 [4 Nov 1975 11 Nov 1975] 45741/76 Heading G2A In a view-finder for a reflex camera, light from the focusing screen 14 is reflected by a first reflector and then a second reflector to an eyepiece, one or other of the reflectors being such as to cause lateral reversal of the image, which is therefore seen in the eye-piece as erect and non- reversed. As shown, light from a photographic subject 22 passes through the taking lens 11, along the optical axis 12, and is reflected by an inclined mirror 13 to form an image 23 on the focusing screen 14, which image is mirror-reversed. The view-finder housing has a roof prism 15 cemented to a step prism 16, the roof prism reversing the image again so that it passes out of the exit face 16b of prism 16 as an erect and non-reversed image. This is reflected again from an inclined mirror 19 to the eye-piece 20. Figs. 1 and 2 show the camera in the normal position, in which the longer dimension of the rectangular film frame is in the horizontal direction. If the longer dimension is to be vertical, the camera is turned sideways, as in Fig. 3. The front part 18 of the view-finder housing, containing mirror 19 and eye-piece 20, is rotatably mounted on the remaining part, and when the camera is turned to the Fig. 3 position, housing part 18 is rotated through 90 degrees, so that the light reflected from mirror 19 is at right angles to its previous direction. Thus the observer looking down into the eye-piece still sees an erect and non-reversed image. In the arrangement of Figs. (not shown) 4-6, the mirror comes before the roof prism instead of afterwards.

Abstract: 1363337 Paramagnetic gas detectors HARTMANN & BRAUN AG 4 Oct 1972 [26 Nov 1971] 45804/72 Heading G1N In a paramagnetic gas detector, e.g. for detecting oxygen, of the type having a test piece rotatably suspended in an inhomogeneous magnetic field, the test piece includes a pair of plates 6, 7, a wire loop 1 and lateral loops 4, 5 which surround the plates 6, 7, arranged in the field, the flow of gas to be analyzed being arranged to be symmetrical relative to the axis of rotation and the plates. As shown, the test piece is suspended by clamping bands 3 and the arrangement is located in a chamber having a longitudinal channel 2 and lateral channels 8, 9 containing the plates. The gas thus flows in the directions of the arrows. The field is provided by permanent magnets 10-13 having tapered ends which terminate in rectangular areas 14, 15, Fig.3, parallel to the plane of the plates.

Abstract: 1,224,815. Gas burners. RADIATION Ltd. 13 March, 1968 [17 March, 1967], No. 43957/68. Headings F4A and F4T. A gas burner comprises a casting 38, Fig. 19, having a recess 39 in which fits the burner ring, the body 38 forming a heat shield for the gas pipes leading to the burner. The gas flows through a main governor 60, Fig. 12, through pipe 60a to a main flow control valve 67 controlled by a flame failure phial 68, Fig. 11, and through pipe 60b to a Venturi-shaped mixing chamber 44 feeding the burner ring through opening (43), Fig. 17 (not shown). A slot (42) in the body 38 locates a pilot burner assembly comprising a ceramic body 48, Fig. 14, containing a standing pilot jet 50 and a heating pilot jet 51 for heating the phial 68. The pilot jet 50 is fed through pipe 59, Fig. 12, filter 57 and pipe 53 whilst the jet 51 is fed from filter 57 through a pilot governor 65, a manual cut-off valve 62 actuated by a slide 74, and pipe 54.

Filed: 1967-10-09
Abstract: 1,155,448. Carbon electrodes. ESSO RESEARCH & ENG. CO. 9 Oct., 1967, No. 46008/67. Heading C1A. [Also in Division C5] A pitch binder for carbon electrodes is made by a process (see Division C5) which comprises (a) heating, under partial reflux conditions, a petroleum hydrocarbon in the presence of activated carbon to form an overhead fraction and a bottoms fraction; (b) separating said carbon from the bottoms fraction; (c) subjecting said bottoms fraction to a vacuum distillation to obtain the pitch product as the residuum. 31 wt. % of a mixture of the above pitch with 5% of carbon black is mixed at 300-325‹ F. with ground delayed petroleum coke that has been calcined at 2000‹F. and of which 100% passes a 4-Tyler mesh screen and 30 wt. per cent passes a 200-Tyler mesh screen. The resulting mixture is moulded in graphite molds and baked in an inert atmosphere at up to 1000‹ C. for 23-5 hours under applied pressure to simulate the weight of the green mix above a Soderberg electrode in an actual furnace. The a/m active carbon prepared by the destructive distillation of wood, lignite &c. is activated by heating e.g. to 800-900 ‹C. with steam or C0 2  and has a surface area of 3600 ft2/gm.

Title: Utilization of ultrasonic echo signals
IPC: G01S15/89
Filed: 1972-10-09
Abstract: 1404783 Ultrasonic inspection devices SIEMENS AG 9 Oct 1972 [14 Oct 1971] 46517/72 Heading H4D An ultrasonic Doppler-effect echo system is provided, in which the visual nature of Doppler display marks is varied in accordance with the time of arrival of the associated echo signals. In the embodiment shown body-fluid duct system 5 is scanned by a pulsed transmitreceive system 1 moved in directions x and y. Cathode-ray tube 15 provides either a B-scan or C-scan display according to which of switch pairs 28, 29 and 33, 34 is selected for applying deflection voltages to its plates 31, 32. Doppler signals in a selected frequency band are extracted at 6, 7 and control the display brightness in three selectable modes. Thus if switch 8, 11 or 16 is closed the Doppler signals are applied to respectively a frequency-to-voltage converter 10, a Schmitt trigger 13 or a timer 18. Timer 18 ascertains the interval between transmission of an ultrasonic pulse and occurrence of a Doppler signal, i.e. the pulse echo time. The echo time is converted at 19 to a proportional voltage (which increases or decreases with increasing echo time) for modulating the display brightness. This enhances the spatial impression of the duct system given by the display. For displaying only or emphasizing echo signals from selected depths in duct system 5, an adjustable delay 23 can be switched into circuit so that timer 18 is operative only a given time after the ultrasonic pulse transmission. Instead of brightness modulation in dependence on echo time, the length and/or thickness and/or colour of display marks may be varied according to echo time. An ink jet recorder may be used instead of cathode-ray tube 15.
