Title: Seed treating process
Inventor: SEVEN RAYMOND P
IPC: A01C1/00
Filed: 1959-06-23
Abstract: In treating seeds to disinfect them and protect them against attack by malignant micro-organisms, the seeds are fed continuously into a vessel provided with agitators, such as rapidly revolving blades or brushes, and, at the same time, at least two solutions are fed separately, as by bucket elevators, into the vessel so that they interact, in the presence of the agitated seeds, to produce, as a coating on the seeds, a desired percentage, based on the weight of the seeds, of a treating agent. The coated seeds are removed from the vessel at the same rate as the untreated seeds are fed in.  The treating agent may be tetramethyl thiuran disulphide or an oxidation product of disodium ethylene bisdithiocarbamate, formed by reacting an aqueous solution of sodium dimethyl dithiocarbamate or disodium ethylene bisdithiocarbamate with an aqueous solution of sodium hypochlorite, hydrogen peroxide, potassium permanganate, or an alkali metal per sulphate, per carbonate, or peracetate.  The treating agent may be a dimethyl dithiocarbamate or ethylene bisdithiocarbamate of zinc, manganese, copper, cobalt, tin, iron, silver, or mercury, formed by reacting an aqueous solution of sodium dimethyl dithiocarbamate or disodium ethylene bisdithiocarbamate with an aqueous solution of zinc sulphate or a salt of manganese, copper, cobalt, tin, iron, silver, or mercury. The treating agent may be methyl mercuric dimethyl dithiocarbamate, formed by reacting an aqueous solution of sodium dimethyl dithiocarbamate with an aqueous solution of methyl mercuric hydroxide; or it may be a hydrated mercury-zinc or copper-zinc chromate, formed by reacting an aqueous solution of sodium chromate with an aqueous solution containing zinc nitrate and mercuric nitrate or zinc nitrate and a copper salt. Alternatively, three separate aqueous solutions of three appropriate salts may be mixed to form the mercury-zinc or copper-zinc chromate. The treating agent may be zinc trichlorophenate formed by reacting an aqueous solution of sodium trichlorophenate with an aqueous solution of zinc chloride; or it may be methyl mercury p-toluene sulphoramide, formed by reacting an aqueous solution of an alkali metal p-toluene sulphoramide with an aqueous solution of methyl mercuric hydroxide; or it may be a copper salt of 8-hydroxyquinoline, formed by reacting an alcoholic solution of 8-hydroxyquinoline with an aqueous solution of a copper salt; or it may be N-trichloromethyl mercapto tetrahydrophthalimide, formed by reacting a solution of tetrahydrophthalimide in alkaline methanol with a solution of perchloromethyl methyl mercaptan in xylene.

Filed: 1922-08-08
Abstract: 205,615. Morris, A. W. Aug. 8, 1922. Sliding latches; preventing operation of; lock mechanism, operated by non-rotating key.-A latch bolt is operated by a plate-like follower, through a slot in which pass locking pins, with waists, which can be set to allow movement of the follower, or which can block it against movement, preventing actuation of the latch bolt. The pins are brought to their inoperative or operative position by a flat non-rotating key on the outside and by a sliding plate forming part of the mechanism on the inside. The follower 23 is carried by the squared central part 22 of the handle spindle 20, and has a pair of pins engaging arms 38 of the yoke 39 through a central slot in which passes the T-head 43 of the shank of the latch, a spring 46 being fitted between a fixed abutment 48 and a shoulder 47 of the latch. Two fixed pins 33 secure the abutment 48 and also the end plates 31, 24 and the disc 30. A third fixed pin 34 works in a curved slot 35 in the follower. Three locking pins 53 pass through slots in the disc 30. The cover plate 31 and a plate 26 secured inside the end cap 24, serve as a key-guide when the key is inserted in a slot 25 in the cap. The pins are secured at their other end by a channel-shaped cap 60. The pins have a tang 54 at the end covered by the cap 60, a cut-away part 55 at the keyhole end, and, in the middle, flattened waists 56 which co-operate with enlarged parts 58 in an arcuate slot 57 in the follower. When the waists 56 of the locking pins are not in alignment with the slot 57, the follower 23 cannot be turned by the handles 21 to withdraw the latch. To turn them to the position for operating the latch, from the outside, a key 61 is thrust into the key-slot 25, when inclined parts 62 contact with the cut-away parts 55 to turn the pins to align their waists 56 with the slot in the follower, allowing it to be turned. To adjust the pins from the inside, a sliding plate 59 is provided below the cap 60. Slots 63<1> in this plate have inclined sides 64, 65. The sides 64 when pulled into contact with the tangs 54 of the pins position the waists for preventing operation of the follower, while when the plate is pushed to contact the sides 65 with the tangs, the pins are rotated into position for allowing operation of the follower. A keyhole-shaped slot 66 in the sliding plate co-operates with a piece 69 on a trigger 70 to prevent sliding of the plate 59 to position the pins for unlocking. Sleeves are provided on the handle spindle and fixed pins 33, 34, to prevent displacement of the discs. The nose 50 of the latch has a flat 49 working in a plate 52 to prevent rotation of the latch A projection 40 on the yoke 39 travels in a slot 41 in the disc 30 to guide the yoke.

Abstract: 1466230 Frequency division SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 21 May 1975 [6 June 1974] 21820/75 Heading G4D An arrangement for dividing by an odd number and delivering a symmetrical output signal (equal mark/space ratio) comprises a switching circuit DV which receives the input pulses CK and delivers these pulses either direct or inverted according to the state of a control signal q 1  ; a counter CN which counts these output pulses; a decoder DF which detects when the count reaches a predetermined value and issues pulses q5 which alternately set and reset a bi-stable FF which in turn delivers the control signal q 1  which also forms the output of the arrangement. The circuit of Fig. 1 divides by 2n-1, where n is the predetermined count, because the bi-stable FF divides by two and the effect of inverting (phase shifting) the input signal is to "lose" a half cycle of the input signal every cycle of the counter (Fig. 2, not shown). In a modification (Figs. 3, 4, not shown) a half cycle delay is introduced between the decoder and bi-stable so the division ratio becomes 2n+1.

Abstract: 1,005,547. Coated foamed material. M. ALCIDE, [trading as LANES RESINE]. May 31, 1963, No. 21966/63. Heading B2E. A cellular material for use as a seal comprises a strip A of foamed resinous material having an adhesive face, the face B of the material to which the adhesive coating C is applied being impervious to adhesive composition, and the face, opposite to the adhesive face, being grooved or otherwise provided with salients providing a small top contact area with the adhesive face of adjacent coils when the strip is wound into rolls for packaging and adhesive protection purposes. The salients may consist of the edges of ridges D arranged at an angle with respect to the longitudinal axis of the strip. The material may be produced by subjecting one face of the foamed resinous material to the action of heat so as to make the face impervious by closing the prevailing parts of the cells thereon, grooving the face opposite the impervious face, applying an adhesive non-drying composition to the impervious face, winding the adhesive strip material into a roll whereby the adhesive face will be covered and protected by the opposite face of the material in the adjacent coils in the roll while the adhesive contacts the opposite face at the tops of the grooves. The grooves may be produced by the action of heat or by a cutting action. The heat treatment of one face, and the application of the adhesive thereto, and the production of grooves on the opposite face, may be effected simultaneously on a plurality of strips disposed side by side and formed from a band or a sheet of foamed material by making cuts F in the latter which are interrupted at one of the faces of the bands or sheets to define connecting zones G between adjacent strips. The connecting zones may be provided to correspond with the ridges in the grooves and are produced by means of a continuous cut made so deep to intersect partially only the grooves so that the zones are constituted by at least part of the ridges which are disposed at an angle with respect to the longitudinal axis of the material. The foamed resinous material may be foamed polyurethane or polyester resin.
