IPC: D04C1/00
Filed: 1934-05-11
Abstract: 433,814. Valve-spring lifters. ZIM MANUFACTURING CO., 3047, Carroll Avenue, Chicago, U.S.A. May 11, 1934, No. 14271. Convention date, Sept. 15, 1933. [Class 61 (ii)] The operating arms 1, 2, of a valve-spring lifter, which are pivoted together at 6 at their rear ends, are opened or closed step by step by a bell-crank lever one arm 10 of which is pivoted at 11 to the free end of the operating arm 2 while the bend pivots slidably in slots 13 in the operating arm 1 and the other arm 14 of the lever is connected to a ratchet lever 15 pivoted about and slidable along a pin 20 between the members of the operating arm 1. This arm, at its rear end, is widened to form side plates 3 between which a handle 21 is pivoted about a pin 23 below the pivot 6 of the operating arms 1, 2. Forward movement of the handle 21 engages an actuating pawl 25 with the teeth on the ratchet lever 15 to move it forwards and open the arms 1, 2, a holding pawl 24, rocking about the pivot 23, preventing its return. A spring 28, secured to the pivot pin 6 is controlled by an external lever to press the holding pawl on to the teeth or to leave it free to rise when the arms are being closed. a pin 5 connecting together the side plates 3 and disposed over a recess 32 in the actuating pawl 25 engaging that pawl, as the handle 21 is retracted, to hold it on to the ratchet lever when the pressure of the spring closes the arms 1, 2 ; at the same time, a boss 33 on the pawl engages the holding pawl 24 with the lever.

Title: Dyeing method
IPC: D06P1/30
Filed: 1965-04-05
Abstract: Cellulose substrates are dyed with soluble sulphur dyes of the general formula R(SSO3M)n where R is a chromophore-containing group and is a group normally included within the class of sulphur dyes, M is an alkali metal or ammonium radical and n is 1 to 6 by applying the dye, e.g. in aqueous solution together with formaldehyde and a metallic salt which is a Lewis acid in the solid state to the substrate, heating the impregnated substrate to solubilise the dye, reducing the dye to the lenco form and subsequently oxidising the reduced dye to develop the colour.  The reduction step is preferably carried out by impregnating the substrate with a reducing agent which is then steam-aged.  Cross-linking takes place between the formaldehyde and substrate and the salts used are salts of bivalent metals of Group II of the Mendel<\>aeeff periodic table, e.g. Ca, Mg, Sr, Ba, Zn and Cd and preferably strong monobasic acids which are at least 50% ionised in normal aqueous solution at 18 DEG C, e.g. HCl, HI, HBr, HNO3, HClO4 and thiocyanic acids.  The strong acid salts of Cu, Cr, Fe, Co, Ni and Al, e.g. copper sulphate may also be used. Conventional oxidising and reducing agents are specified.

Abstract: 694,501. Sorting by weighing. NATIONAL COAL BOARD, and WATERS, P. L. June 7, 1951 [June 8, 1950]. No. 14357/50. Class 143. [Also in Group XXX]. An apparatus for sorting trucks in a coal mine comprises a rail track having a section which; when supporting a coal loaded truck remains rigid, but which, when loaded with a truck containing stone, yields and operates an indicator and/or rail point operating mechanism. The main track b has a yielding section a supported on a weigh beam d, and adjacent this section is a rotary arm f which, as each truck passes over the section, closes a switch g. This switch is in circuit with one of a pair of lamps m, I according to the position of a change over switch contact i which, when the section a has been depressed, is raised from its normal position, in contact with contact j' into contact with a contact k by the beam d. The contact j, which is arranged to have two positions of adjustment only, is secured to an arm h which projects between the main rails b and which is engaged by each stone containing truck as it passes off the section a and so returns the contact j to its lowest position. In modifications (not shown) instead of, or in addition to, the lamps the circuit may contain automatic counting mechanism, or a mechanism for operating rail points to divert the stone containing trucks onto a different track.

Title: Method and device for severing the heads of gutted fishes by a  wedge-shaped cut
IPC: A22C25/14
Filed: 1972-03-28
Abstract: 1385381 Treating gutted fish NORDISCHER MASCHINENBAU RUD BAADER 28 March 1972 14523/72 Heading A2U A method of severing heads of gutted fishes by a wedge-shaped cut wherein the head of each fish is aligned and secured and the head severed, and then the parts containing the collar bones are separated from the head by cuts guided into the gill cavities. The method is particularly applicable to fishes in which the gill and abdominal cavities have been opened, in which case, the fish is fixed in position by straddling the gill cavity and supporting the head between the arc of the lower jaw, whereupon the body is cut off and the parts containing the collar bone severed by cuts directed downwardly from the neck. The method may be carried out in the device shown in Fig. 1 which comprises a conveyor 2 capable of stepwise motion, head severing device 4 which includes circular knives 42, 43 arranged to contain an obtuse angle with their cutting edges, and a separating device 5 which includes circular knives 52, 53 arranged in a common plane. Each fish is supported on the conveyor in a receiving means 3, as indicated in Fig. 2 (not shown). In operation, a fish is positioned in receiving means 3 and during an advancing movement of the conveyor, support 35 (Fig. 2, not shown) pivots upwardly and enters the spread open abdominal cavity, thereby lifting the vertebral column. After further movement of the conveyor, knives 42, 43 pivot about axis 45 and remove the head from the body. The collar bones are removed from the head by knives 52, 53 after a further movement of the conveyor.

Title: Removal of so2 from sulphite-and/or bisulphate containing effluents
IPC: C01B17/50
Filed: 1977-04-06
Abstract: Sulphite- or hydrogen-sulphite-containing waste waters are purified with simultaneous substantial recovery of sulphur dioxide by establishing an acidic pH range in the sulphur-dioxide-containing waste water and expelling the liberated sulphurdioxide at elevated temperatures using air as far as a residual sulphurdioxide concentration of 1-10 g of SO2/l of waste water. After the treatment with air, the waste water is reacted at temperatures of 20 to 230 DEG C with industrially pure oxygen at pressures of 1 to 30 bar at a redox potential between 300 and 600 mV up to virtually complete formation of sulphate. The redox potentials are based on a measurement which is performed at a measurement position outside the reaction vessel using a platinum electrode having an Ag/AgCl comparison electrode.
