Inventor: KATAJAMAEKI SEPPO
IPC: D21H27/30
Filed: 2003-10-27
Abstract: The invention relates to cardboard used in authenticity products, comprising a fiber matrix having two surfaces, whereby the second surface of the fiber layer has a layer of surface sizing containing a marking agent in a particle form, its particle size being smaller than 50 μm. By incorporating the marking agent into the surface sizing, the particles of the marking agent can be attached to the board, at the same time decreasing their total consumption by 80 to 90% compared with a case where they would be added to pulp. By using particles of a size less than 50 μm, a top free from streaks and roughness can be formed, which streaks might otherwise weaken the quality of the product.

Abstract: 1,253,224. Nickel plating. STAUFFER CHEMICAL CO. Nov.21, 1968 [Dec.4, 1967], No.55225/68. Headings C7B and C7F. An electroless nickel solution comprises nickel ions, hypophosphite ions, and fluoborate and/or sulphamate ions, the pH of the solution being 4.0  to 7.0. The preferred sources of fluoborate and sulphamate ions are Ni fluoborate and Ni sulphamate respectively; this avoids the introduction of undesirable extraneous ions into the bath. In order that high nickel ion concentrations may be achieved in the bath, glycolate and/or acetate ions may be added thereto, preferably as the corresponding acid. The pH of the solution is preferably maintained above 5.3 using a borate buffer, and plating rate accelerators such as ammonium fluoride and/or thiourea may be added. A wetting agent may also be added, with a non-ionic type such as polyoxyethylene 2-ethylhexyl phosphate being preferred, but other suitable agents are mentioned. The ranges of concentrations for the above mentioned ingredients, not all of which need be present simultaneously, are: - Nickel ion 1 to 40 g/l Hypophosphite ion 59 to 150 g/l Fluoborate and/or sulphamate ion 2 per Ni ion Borate ion 15 to 50 g/l Glycolate ion 7 to 35 g/l Acetate ion 10 to 25 g/l Ammonium fluoride 2 to 10 g/l Thiourea 0.2 to 0.8 p.p.m. A solution as described above can be used in an electroless-electrolytic process, where, after deposition of a first layer electrolessly, electric current may be applied so that a second layer is deposited electrolytically. The following substrates are catalytic and may be directly nickel-plated: Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, Pt and Ag, whilst Bi, Cd, Sn, Pb, Zn, plastics, glass, and wood must be sensitized prior to plating by known methods, e.g. SnCl 2  /PdCl 2  . Prior cleaning and degreasing may be necessary and suitable procedures are described.

Abstract: 1,259,061. Line selection circuits. BURROUGHS CORP. 22 May, 1970 [17 Oct., 1969], No. 24786/70. Heading G4H. A system for selecting one only of a number of stations any of which can call for attention at the same time by applying a signal to a corresponding lead RA00 to RA32, and for indicating which station has been selected, comprises a number of selector levels each having a number of selection circuits SC, each selection circuit having means giving an output on one of a number of leads in response to a signal on one or more corresponding inputs, all the outputs from each selection circuit being combined in an OR gate to form one of the inputs to a selection circuit in the next level, the outputs from the selection circuits in the second and subsequent levels being used to enable gates G controlling the outputs from corresponding lower level selector circuits. The first level to which the input lines RA00 to RA31 are applied consists of selection circuits SC1-0 to SC1-7 each of which scans four input leads and selects the first one having a signal. The outputs from each circuit are combined in an OR gate 50 and applied to the inputs of a selection circuit SC2-0, SC2-1 in the next level each of which again selects one of the four inputs having a signal. The outputs of each of these selection circuits are combined in OR gates 52 and form the inputs of the selection circuit SC3-0 in the last level, which again selects one of the marked inputs. The four output leads of each selection circuit in the first two levels are applied to a group of gates controlled by a common signal. Gates G1-0 to G1-3 are controlled from gate G2-0, gates G1-4 to G1-7 from gate G2-1, and gates G2-0 to G2-1 from selection circuit SC3-0. When a number of signals are applied simultaneously to inputs RA00 to RA31 the first level selection circuits having inputs each operate to select one, and the two groups of four OR gates 50 pass corresponding signals to selection circuits SC2-0 and SC2-1 each of which selects one of the inputs and applies corresponding signals through OR gates 52 to selection circuits SC3-0. The single output from this selection circuit enables one of the gate groups G2-0 or G2-1. The single output from the enabled gate enables one of the gate groups G1-0 to G1-7 and the single output identifies the selected one of the calling stations. The selection circuit (Fig. 2, not shown) used in the first level comprises a counter, started by a signal on any of the four input leads, adapted to enable four gates in turn. The gate outputs are combined in an OR gate to stop the counter as soon as the first marked lead is found. The other selection circuits (Fig. 3, not shown) each consist of an AND gate for each input lead, each input also being connected via an inverter with the AND gates of all lower priority lines. A number of such selection circuits SC3-0 to SC3-2 may be provided in parallel in the third stage having different priority arrangements, so that the desired priority order can be selected by a signal from register 54.

Abstract: 1,259,210. Digital electric computer. ING. C. OLIVETTI & C. S.p.A. 6 Nov., 1969 [11 Nov., 1968], No. 54512/69. Heading G4A. The invention relates to an electronic computer having a stored program and arranged to obey jump instructions. A desk top computer has a delay line memory holding sixteen registers each containing thirtyone eight bit words interlaced to enable corresponding bits of all the registers to be available at the same time. The computer can perform serial addition, multiplication, subtraction and division under the control of instructions arranged in three formats. A first format has a single eight bit word, the first four bits defining the memory register on which an operation is performed, the last four defining the operation, a second format consisting of two eight bit words allowing input and output of information, modifying instructions and controlling transfer of memory blocks between the delay line memory and an external endless tape cartridge magnetic memory, and a third format made up of one word all eight bits of which indicate a function code. The computer may perform three types of jump instructions, a conditional or unconditional jump to a specified reference instruction, a jump wherein a reference instruction is inserted in a specified register, a jump then being performed to a second reference instruction, a subroutine being ended by a return to the specified register and a jump then being performed to the reference instruction defined by the register and a third jump instruction allowing operations involving nested subroutines to be performed. In the third type a jump instruction differs from a reference instruction by having the first bit of the instruction B1=0 while a reference instruction has B1=1. When a jump instruction occurs the subroutine referenced must begin and end with the corresponding reference instruction and the program jumps to the reference instruction at the beginning of the subroutine by searching through the memory until the reference instruction is found and compared with the jump instruction and converts the jump instruction to a reference instruction. When the second reference instruction is reached it is treated as a jump instruction and search is commenced at the first digit of the first register rather than at the beginning of the register in which the reference instruction occurred. When the converted jump instruction is found the program is continued with the next following instruction. If nested subroutines are to be performed they must be stored in order of operation. The Specification is similar to Specification 1,259,209 which also describes the endless tape cartridge. Indirect addressing.-The address format of a first format instruction contains the address of a memory register whose least significant two digit places contain the address of a register to be operated on by the instruction. Ten registers may be addressed indirectly and any quarter of each of these registers may be addressed separately. An instruction having an indirect address is preceded by a third format instruction.

Abstract: 1,265,868. Wells. DRESSER INDUSTRIES Inc. 31 July, 1969 [15 Nov., 1968], No. 38497/ 69. Heading E1F. A well tool anchor, e.g. on a packer or bridge plug consists of a slip 100 (Fig. 5) which is loosely mounted or pivoted at 136 on the tool so that it can move between a position with the axis 108 along the tool axis, when edges 120, 122 (with optional 'teeth) grip the walls of the well bore or outer tube and a position with the axis 112 along the tool axis, when the slip has a diameter 130 less than that of the well bore or tube. The slip is pivoted into the anchoring position by abutments engaging the upper and lower edges 114, 116, or only one edge if the slip is mounted on pivots 68 which limit its axial displacement, and is released by abutments such as 70. The slip is normally held in the released position by leaf spring 88. The slip may be operated by rotation of a body member 36 to move a screw-threaded upper head 46. The slip is released by rotation in the opposite direction or by a straight pull on the body member 36 to shear a shear pin 92. In other embodiments the upper and lower heads are moved under the control of a T-slot connection between the centre body and a block body (214) on a drag block assembly (212, Figs. 8A-14, not shown) or by hydraulic pressure developed within the tool after dropping a valve and ball (427) onto a seat (426) at the bottom of the tool to seal the lower end  of the tool (Figs. 15A-16C, not shown). The valve seat is designed to shear at a predetermined pressure above the slip operating pressure, so that the obstruction caused by the ball is removed. In another embodiment (Figs. 17A-21B) slips are used in a bridge plug connected to a sinker with. a J-slot connection, and operated by differential pressure in the well.  Releasing the slip may be facilitated by forming it with an offset projection, e.g. 287, Fig. 10A, not shown) on the axial end to which the engaging load is not applied, so that engagement of the projections with an abutment face will tend to relieve the slip. Alternatively, the abutment face (384, Fig. 13, not shown) loading the slip may be supported on tapered blocks (372) which are withdrawn by removal of a sleeve (306) supporting them to release the slip.
