Title: Apparatus for continuously monitoring the quality of a flowing particulate material in respect of its granularity and purity
Inventor: BROWN THOMAS JAMES ALBERT
IPC: G01N21/47
Filed: 1962-03-28
Abstract: 954,717. Photo-electric inspection devices. HENRY SIMON Ltd. March 14,1963 [March 28, 1962], No. 11833/62. Heading G1A. The invention relates to apparatus for monitoring dry fluent material as to its colour and granularity. The proposed apparatus may be used with flour, salt, starch, hydrated lime and like materials. In it an auger 5 is driven to separate from the main flow of material along a main trunking 2 a proportion fed to a sample chamber 1 having a transparent window 6. A valve 7 with a counterweight 8 maintains the material passing through the sample holder in a uniform state of consolidation. The monitoring is done by comparing the diffuse reflectivity of the material in the sample holder 1 with that of a reference surface 14. For this purpose light from a lamp and reflector 12 is collimated at 11 and directed by rotating eccentrically mounted mirror 9 alternately towards the sample and the standard. Diffuse light from the sample reaches photo-cell 18 through adjustable shutter 23 and that from the sample through preset attenuator 27. A filter, preferably having maximum transmission over the 525 to 625 millimicron band, is placed immediately in front of the cell. Any difference in the light received by the cell over the two paths gives an A.C. error signal whose phase is compared with the output of a device coupled to mirror drive motor 13 and fed to a motor 22 which adjusts shutter 23 to reduce the error signal to zero. The position of the shutter, and thus the reflectivity of the sample, is indicated by pointer 24 and also recorded at 26. Limit switches 25 operate an audible or visible alarm if the material characteristics pass outside a predetermined acceptable range.

Title: Electromagnetic switches with optional manual operation
IPC: H01H51/06
Filed: 1959-04-08
Abstract: 858,164. Electromagnetic relays. BENDIX CORPORATION, [formerly BENDIX AVIATION CORPORATION]. April 8, 1959 [April 17, 1958], No. 11884/59. Class 38 (5). A bridging contact of an electromagnetic relay may be actuated and latched by manuallyoperable means which is released by energization of the relay. The electromagnet 13 has a magnetic case 14 enclosed in a cover 11 with an insulating cap 15 having legs 16 engaging the top of the case 14. An armature contact plate 29, having ears 37 projecting between the legs 16, is biased by a spring 31 to bridge fixed contacts 18, 19 secured in the cap 15. The manually operable plunger 23 is biased upward by a spring 26 which also tends to rotate the plunger clockwise when viewed from below. A transverse pin 24 carried by the plunger 23 is normally located in a slot 21 in the cap 15 and a projecting key 25 on the plunger is at rightangles to a corresponding slot 30 in the armature plate 29. For manual operation the plunger 23 is pressed and turned so that it engages and moves the plate 29 away from the contacts 18, 19 and the key 25 latches into the slot 30 with the pin 24 engaging the underface of the cap 15. Energization of the magnet 13 moves the plate 29 further downward and releases the key 25 from the slot 30 so that the spring 26 rotates the plunger until the pin 24 strikes a stop 28 and then moves it upward to its initial position. The relay may be normally open with resiliently mounted fixed contacts engaged by the plate 29 in the position to which it is moved by the plunger as well as when attracted by the electromagnet. The key 25 may be provided with bevelled shoulders so that the plunger can be unlatched by hand. Alternatively means operable through the cap 15 may apply downward pressure to plate 29 to release it.

Title: Improved machine for beating, squeezing, kneading or briquetting plastic masses or fibrous materials
IPC: B29B7/50
Filed: 1938-04-22
Abstract: 513,871. Grinding plastic materials ; kneading &c. apparatus. I.G. FARBENINDUSTRIE AKT.-GES. April 22, 1938, Nos. 12086 and 12087. Convention dates, April 23, 1937 and Oct. 23, 1937. [Classes 59 and 86] [Also in Groups V and VIJI] A machine for squeezing, beating, kneading, or grinding plastic material such as rubber or fibrous material such as wool felts, comprises a rotatable roll A mounted coaxially or eccentrically in a counter mould B providing a space therebetween, and means for causing relative oscillation between the roll A and mould B. Circular oscillations may be produced by mounting the mould B on springs D\ D<2>, and providing rotary shafts with unbalanced weights C<1>, C<2>. Alternatively, the roll may be oscillated. The oscillation may be in a plane at right-angles to the axis of the roll. The surfaces of the roll and mould may be profiled; they may be undulated or fluted or separate pins or projections may be arranged in line or in staggered formation, or they may be provided with combs R<1>, R<2>, Fig. 3, forming alternately wide and narrow crevices F, G, the edges of the combs R<1> being inclined to the combs R<2>. The edges may diverge towards the sides to balance the strains. The roll and mould may be heated or cooled, passages M<1>, M<2> being provided. The counter mouJd may be in three parts, each carried by springs and oscillated by unbalanced weights rotated in recesses within the parts. The weights are slidably mounted on shafts keyed to and projecting laterally from a shaft mounted in the two outer parts and passing through the middle part. The weights are so disposed that a balanced arrangement is produced. In other modifications the countermould is a hollow cylinder within which the roll is mounted coaxially or eccentrically. Either of, or both the roll and cylinder oscillate and the outer cylinder may rotate as well as the roll. One or both may be conical. The circular oscillations may be in opposite directions. For briquetting, the roll and cylinder are similarly profiled and rotate in the same direction with the same or different speeds. For grinding or mixing they are rotated in opposite directions. In one form of briquetting machine, Fig. 7, the cylinder B<4> is driven by rolls L<1>, L<2>. The roll A is resiliently mounted and its axle is hollow and has an unbalanced weight C<3> rotating therein. Material is fed by a conveyer 0 and passes by a guide plate O<1> to the roll A. The briquettes are directed to a discharge conveyer O<3>. In another form the roll and cylinder both oscillate and are mounted in frames which are resiliently supported and carry rotating unbalanced weights.
Patent GB-629131-A (GB)
Title: Improvements relating to the production of elongated metal tubular parts
IPC: C22F1/00
Filed: 1947-05-05
Abstract: A method of making capillary tubing, e.g., for a hypodermic needle, which splits longitudinally instead of breaking in two when bent, comprises reducing a ductile metal tube in one or more stages, by excessive cold working, each stage being preceded and followed by heating to a temperature below that which would destroy the fibrous structure produced previously.  This method may be applied to the metals referred to in Specification 565,061, [Group XXII].  The heating and cold working may be repeated a number of times with an optional final heating.  The temperature to which the work is heated and the degree of cold working, for any particular metal or alloy necessary to produce the desired fibrous structure is found by experiment, micro-photographic examination at the various stages of the operation, and by determining the brinell hardness of sufficiently-worked material. Details are given of the treatment required in the case of particular sizes of work pieces made of the steel known under the Registered Trade Mark "Staybrite," stainless steel containing 12 per cent chromium, 12 per cent of nickel and 0.12 per cent of carbon, mild steel containing 0.12 to 0.25 per cent of carbon, 0.5 to 0.8 per cent manganese, and not more than 0.05 sulphur and phosphorus or 0.25 of silicon, and commercial phosphor bronze, containing 95 per cent of copper, 4 of tin and 0.1 of phosphorus, the rest being zinc and impurities.  The best temperature for stainless steel is 800 DEG C., for mild steel 715 DEG C., and for the phosphor bronze above 420 DEG C., these temperatures being about 60 per cent of their melting points in the absolute scale. Stainless steel tube made in this way may be finally tempered by heating to 400 DEG -420 DEG C. in a salt bath and quenched.
