Title: Measuring the intensity of light
IPC: G01J1/42
Filed: 1973-06-25
Abstract: 1435327 Light intensity measurement corrected for background radiation DURST AG 25 June 1973 [24 June 1972 23 May 1973] 30052/73 Heading G1A In a device for measuring incident light intensity, a photo diode 1 is periodically exposed to the incident light by means of a movable diaphragm 16 (or a liquid crystal (25) Fig. la (not shown)) which is controlled by a pulse generator 10 and during the "dark" periods the photo-cell's output signal is supplied to a condenser 17 by way of switches 8, 9 and 11, also controlled by the pulse generator 10 to cause the condenser 17 to be charged by the photo-cell's output signal. The switching is such that during the periods of exposure to incident light the condenser 17 is corrected with the photocell's output signal to an input of an amplifier 4 in order to correct the signal for "background" radiation. The corrected photo-cell signal is thus amplified and fed to a cathode ray oscilloscope 19 and a logarithmic amplifier 18. The logarithmic amplifiers output is corrected under the control of a switch 20 to a store 22 which, in turn, is connected to an analog or digital indicating unit 23.

Title: Improvements in or relating to the conveyance of goods through furnaces and the like
IPC: F27B9/20
Filed: 1930-10-08
Abstract: 362,078. Step - by - step conveyers. SMALLWOOD, A. and FALLON, J., British Mills, Cornwall Road, Smethwick, Birming- ham. Oct. 8, 1930, No. 30074. [Class 78 (i).] In a reciprocating bar conveyer having alternated series of carrier bars which are each adapted for movement at a common load-carrying level and at a lower level, each series of bars is lifted into and lowered from the load-carrying level only when moving at the same synchronized forward speed as the other series whereby the load is transported uniformly without any relative movement between it and the carrier bars in the direction of load traverse. As shown applied to a continuous furnace for heating metal sheets, bars, &c., the hearth is constituted by two alternated series of longitudinally reciprocating bars 1, 2 extending through the furnace and the loading and unloading extensions. The bars are faced with interlocking refractory blocks 8 or may have heat resisting metallic facings and are supported on a number of balanced pairs of cross girders 22, 23, each supporting alternate lines of bars. The girders are slidably supported by short rail tracks 24 upon wheels 25 mounted on the opposite ends of rocker arms 26 arranged in pairs on opposite sides of the furnace and interconnected in series by levers 27, links 28, 29 and intermediate levers 31 operated to raise the bars alternately by a cam 34, Fig. 5, coacting with an oscillating frame 33 on the link 28. Reciprocating motion of the bars is derived from a cam roller 12 mounted on a shaft driven from a motor 9 through a speed-reducing gear 10, and having a groove 13 in which engage opposite rollers 14, 15 carried by crossheads 16, 17 connected by links 18, 19 to cross girders 20, 21 to which the forward ends of the two series of bars are respectively attached. The form of the cam groove is such that when both sets of bars are in load-carrying position they are moved forward with the same speed. The rocking cam 34 is driven from the shaft 37 by gearing 36. The conveyer may be reversed and may thus be applied to a single-ended furnace. The bars may be curved for application to circular furnaces.

Abstract: 715,145. Axial-flow compressors. UNITED AIRCRAFT CORPORATION. Dec. 28, 1951 [Feb. 27, 1951], No. 30296/51. Class 110(3) [Also in Group XXII] In a stator construction for an axial-flow compressor, comprising a series of radially-extending stator vanes supported by a shroud, the shroud is in the form of spaced apart, concentrically arranged ring elements connected together to prevent relative motion between them. The outer ends of stator blades 10, Fig. 3, are inserted into a support ring 40 by a punching operation in which each blade acts as a punch, backed up by a die 66. A clamp 64 engages each blade and drives it through the ring 40. A spacer 44, Fig. 6, is then attached, as by welding, to the ring 40. and a further ring 42 is attached to the spacer. The blade 10 is then punched through the ring 42, spacing members 68 being used during this operation. A further spacer 46, Fig. 2, is then attached. To improve the punching action, the trailing edge of the blade may be cut back at 67. The inner end of each blade 10 is inserted into a notch 74, Fig. 7, shaped approximately to the blade contour and formed in a flange 76 of a ring 75. The blade is notched at 82 to engage a flange 72 of a ring 70. The rings 70 and 75 are then secured together, as by welding. Angled surfaces 86 and 87, on the flange 72 and blades 10 respectively, co-operate to provide a wedging action on assembly. The shroud ring formed by the parts 40, 42, 44, 46 may be made up of two or more segments. In any case, the ring is split into halves prior to assembly of the compressor, to permit the rows of stator blading to be intercalated with the rows of blading of the previously-assembled rotor. Spacer rings 34 are inserted between each row of stator blading and have lugs 36 which locate the stator assembly relative to the casing 4.
