Patent GB-854357-A (GB)
Title: Apparatus for determining the presence of oxidizing agents
IPC: G01N31/22
Filed: 1959-04-01
Abstract: A sealed transparent tube containing a granular inert solid carrying N,N,N1,N1-tetra-phenylbenzidine or N,N1-dimethyl-N,N1-di-phenylbenzidine may be used to determine the presence of an oxidising agent in a gas by breaking the seal and passing the gas therethrough; a colour change to blue or to red-violet respectively is effected if an oxidising gas is present. Chlorine and bromine may be detected, but when nitrogen dioxide is to be detected sulphuric, hydrochloric, perchloric, trichloracetic or p-toluene sulphonic acid should also be present. A suitable inert solid is silica gel with or without sand.  10 c.c.s of silica gel may be mixed with 0.1-300 mg. of the reagent, heated to 120 DEG C. for 45 mins., allowed to cool and mixed with 0.3-1.2 c.c.s of 47% sulphuric acid to which there may first be added 0-1.2 c.c.s water and the mixture agitated until dry and free flowing.  The acid may be omitted if only Cl2 and Br2 are to be tested.  If desired, to prevent premature colour formation during storage, an anti-oxidant may be added to the tube: suitable antioxidants are silica gel impregnated with a strong solution of pyrogallol which has been mixed with a caustic soda-asbestos composition; and equal parts of MnCl2 and LiOH.H2O.  If desired, an ampoule containing silica gel impregnated with sulphuric acid and a second ampoule containing sand (or if desired other non-adsorbent carrier such as glass powder or beads, or talc) coated with reagent may be provided and the contents mixed in a bottle for filling into tubes which are sealed and used for test purposes.  The detecting composition may if desired be held in position in the sealed tube by means of glass wool or tape so as to form a column or bed, and after breaking the seal the gas may be aspirated therethrough.  Such tubes may be employed to give quantitative results by comparison of the length over which coloration appears with a calibrated scale.

Filed: 1918-07-17
Abstract: 129,804. Chopin, M. July 17, 1918. Multiple-indication apparatus.-The content of a principal variable of furnaceflue gases, such as the carbonic acid content, is determined by measuring electrically t h e change in the conductivity or in the density of a solution through which the gas is passed. The difference in temperature between the air supply and the flue discharge may also be represented by an electric current, and the indicators of the measuring-devices may be correlated to obtain a direct reading of the total losses. The carbonic acid content and the temperature-difference may be represented by the strengths of electric currents in circuits 1, 2, Fig. 1, including ammeters 3, 4 the pointers of which cross, the point of intersection lying within a scale 9 representing total heat loss. A single galvanometer may be employed alternately for two circuits with independent scales, a hand-set pointer being provided to be set to the first position of the needle and by its .intersection with the needle in the second position give the total losses.

IPC: B25B23/06
Filed: 1958-04-15
Abstract: 871,948. Screw-driving attachments. CALMORE BUFFALO Inc. April 15, 1958, No. 12008/58. Class 83 (3). A screw-delivering attachment for a poweroperated screwdriver 1 comprises a hopper 3 adapted to be mounted on the screwdriver, a collet 47 slidable on the bit 50 of the screwdriver, a screw delivery tube 66 between the hopper and collet, and means 23 for feeding screws to the tube in accordance with movements of the bit through the collet. As depicted, the hopper is screw-threaded to the air line 2 of the screwdriver and provided with a magazine 14 to which screws are delivered by an elevator 9 connected, by a pre-set adjustable telescopic link or (as shown) by a link 63, to the collet assembly. Thus approach of the screwdriver towards the collet, against the'influence of a spring 61, during the driving of a screw raises the elevator in the hopper. An edge 11 beneath the hopper limits downward movement of the elevator and collet, and a screw 12 in the edge of the elevator and moving in a slot 13, limits upward movement of the elevator. An inclined slot 18 in the top of the elevator collects screws 16 from the hopper and a similar slot 15 in the magazine 14 receives the screws, fed by gravity, when the elevator is raised. An escapement 23 on the top of the magazine is oscillated about its pivot 24 to feed the screws singly to a shoot 20, Fig. 9, connected to the tube 66 and secured by a cap 22 to the end of the magazine. The arm 31 of a lever pivoted to the magazine oscillates the escapement, against the influence of a spring 25, by contact with its outer edge, the other, telescopic arm 29 of the lever being connected to the elevator. As depicted in Figs. 1 and 2, the bit is in the retracted, loading position, in which a screw, previously trapped by a sharp bend 70 (Fig. 3, not shown) in the flexible tube 66, has passed into the collet. A curved finger 26 on the escapement obstructs the entrance of shoot 20, preventing movement of the screws in the magazine. Upon depression of the screwdriver to drive the screw in the collet, the elevator is raised, rocking lever 29, 31. This moves escapement 32 to the position depicted in Fig. 7, releasing the lowermost screw, which falls into tube 66 but is trapped by the sharp temporary bend 70 (Fig. 3). The next screw in the magazine is prevented from following the lowermost screw by a spring-pressed finger 33 on the escapement which bears against this screw but releases it when the escapement is returned by withdrawal of the bit. Incorrectly positioned screws are cleared from the top of the magazine by a slide 36 engaging dovetailed ways on the top of the magazine and operated by the bent end 45 of lever 31. A slot 40, Fig. 5, in the underside of the slide receives the heads of the screws and is adjustable in height by a strip 41 operated by nuts 43. The collet is split into at least two parts held together by springs 55 and lined with a nylon bush.
