Title: Method of and apparatus for making chemically treated sanitary napkins
IPC: A61F13/00
Filed: 1927-12-01
Abstract: 298,801. Marks, E. C. R., (Cellucotton Products Co.). Dec. 1, 1927. Catamenial appliances.-An absorbent pad for sanitary bandages comprising several layers of absorbent material such as thin crepe paper, some or all of which are treated with a deodorant or disinfectant, is made by winding a strip of the absorbent material on to a drum and applying the chemical] to separated, parallel, .circumferentially extending zones during the winding . The apparatus shown comprises a hopper 11 containing the powdered chemical, near the bottom of which is mounted a rotary agitator 14. At the bottom of the hopper are fitted a manually adjustable plate 18 and a plate 8 pressed downwardly by a spring, not shown, both resting on a rotating drum 16. The powder carried under the plate 8 drops into a set of spaced troughs 25, of which only one is shown, from which it is deposited on to the paper as it is wound on a drum 9. Particles adhering to the drum 16 are removed by a brush. When the number of layers constituting a single pad has been wound on, a coloured separating layer 9a may be added. The layers for three pads may be wound on without stopping the machine. The troughs 25 jarred by a reciprocating lever 51 driven by an electromotor to prevent adhesion of the powder to the sides. The agitator 14 is connected to the driving gear through an electromagnetically operated clutch, the circuit of which is closed only during a predetermined number of revolutions of the drum 9 by a switch 42 operated by a mutilated cam 46 on a starwheel 45 driven by a finger 45a on the shaft 10; powder is thus applied to a certain proportion only of the layers. Alternative means for controlling the agitator automatically or by hand are described. When sufficient layers have been wound on the drum, the material is unwound and cut into strips by circular saws between the zones of applied material.

Title: Improvements in the manufacture of viscose articles, for example, artificial filaments
IPC: D01F11/02
Filed: 1946-11-06
Abstract: Regenerated cellulose articles, e.g. artificial filaments, made by the viscose process are purified by subjecting them while in the gel state to successive or simultaneous treatment with a dilute aqueous solution of chlorine dioxide or chlorous acid and a dilute aqueous solution of a sequestering agent such as sodium hexamethaphosphate. The filaments may first be subjected to a pre-wash with water to remove some or most of the acid carried over from the coagulating bath.  Chlorous acid is preferably formed in solution by the action of an acid on an alkali metal chlorite, and the acid so employed may be added directly to the solution or may be present as residual acid in the filaments. Examples are given, in one of which, viscose yarn is purified by washing first with aqueous sodium hexamethaphosphate at 57 DEG  C., then with an aqueous solution of sodium chlorite containing sulphuric acid and sodium hexametaphosphate at 57 DEG  C., then with water at 57 DEG  C., then with aqueous ammonium sulphide at 40 DEG  C., and finally with water at 57 DEG  C.

Patent GB-971865-A (GB)
Title: Arrangement for reconverting shilling and penny amounts represented as decimal poundsterling values
IPC: G06F7/46
Filed: 1963-08-22
Abstract: 971,865. Decimal-sterling conversion. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 22,1963 [Aug. 22, 1962], No. 33258/63. Heading G4A. Decimal fractions representing pounds are converted to shillings and pence by multiplication by 20 and 12. The accumulator comprises eight electromagnetic decade counters (Fig. 2) and the conversion involves three steps. First, stages 6 to 8 are cleared and stages 1 to 4 are doubled. A carry from stage I is stored in R S and represents tens of shillings, units being found in stage I. Second, stages 2 to 4 are transferred to stages 6 to 8. Third, stages 6 to 8 are doubled and are added into stages 3 to 5 at least. Any carry from stage 2 is stored and represents tens of pence the units being found in stage 2. As an example of the techniques used, the first step will be described. The counter is of the kind in which the contents are represented on read-out by a single pulse appropriately located in a time interval; a pulse occurring in the first time slot of an interval represents 9, in the last time slot it would represent 0. At the beginning of the first step contacts R A and R B are operated (Fig. 6). During a read-out cycle ten J pulses are applied to commutator JV and to the contacts RZ1-2 to RZ1-8, Should the first order contain 6, the fourth J pulse will energize RZ1 to close contacts RZ1-2. The remaining 6 J pulses will be applied to solenoid MZ1 to enter 6 into the first order. A carry pulse is generated in this case to energize R S, a self-holding relay, and thus contact Sh-T. In this way the first five orders are doubled. To clear orders 6 to 8, the contacts R B operate to connect J V to a contact representing the 9-complement of the contents of these orders. At the end of the read-out cycle, stages 6 to 8 all read 9 and the provision of an in-carry signal clears them. The other steps are similarly carried out. Carry due to the doubling of orders 6 to 8 is anticipated a carry from order 6 being entered directly into order 2. If the fifth and sixth orders contain values from 33 to 39 or 66 to 69 a rounding pulse is entered into the fifth order. The decimal equivalents of exact pence either give a four order fraction or thereafter 3 or 6 recurring.
Patent GB-1354410-A (GB)
Title: Fastenable pivotable structures
IPC: A01B73/04
Filed: 1971-07-15
Abstract: 1354410 Agricultural implements MASSEYFERGUSON Inc 15 July 1971 [29 July 1970] 33267/71 Heading A1B [Also in Division E2A] A fastenable pivotable structure comprises first and second members 10, 38 pivotally connected together for angular movement relative to each other about a pivot axis 78, each member having a structure defining an opening to receive a fastener 110, the openings be alignable by effecting angular movement of the members about the axis 78, and the fastener being capable of extending through the aligned openings. A cam 112 is mounted on the fastener and one of the members has structure providing a thrust surface engageable with the cam, and there are operating means, e.g. a handle 116 whereby angular movement of the cam can be effected. The arrangement is such that when the fastener extends through the aligned openings and the angular movement of the cam is effected the cam engages the thrust surface and effects relative angular movement about the pivot axis of the members whereby the fastener is gripped by the structure defining the openings. As shown, the member 10 is the main gang of a harrow and the member 38 is  a folding wing of the harrow. The main gang 10 includes a gang beam 12 to which two standards 14 are attached. A plurality of discs 20 are rotatably supported by the standards 14 and a scraper 22 is also attached to the main gang 10. The folding wing 38 includes a gang beam 40 which carries standards 42 which rotatably support a plurality of discs 48, and a scraper 52 is attached to the wing. The structure attached to the main gang 10 includes two main plates 69 and 70 welded to the gang beam 12 and having openings for a hinge pin 78 and the structure attached to the folding wing 38 includes two main plates 73 and 74 which are welded to the gang beam 40 and which also receive the hinge pin 18. The openings for the fastening member 110 are provided in the plates 69 and 70, in the gang beam 12 and also in the plates 73 and 64. The opening in the plate 73 receives the cam 112 which is eccentrically positioned on the shank of the member 110; the other openings only receive the shank of the member 110 and hence rotation of the fastening member by means of a handle 116 moves the two structures apart causes binding of the shank in the openings. The cam 112 is attached to the member 110 by a pin 114 which extends from the surface of the cam so that when the member is rotated the pin 140 moves behind a bracket 118 and prevents the member from working out of the openings. To assist in moving the folding wing relative to the main gang a spring 82 or two springs is or are provided. A pair of brackets 120 and 121 are provided on the gang beam 40 to cooperate with a bracket 122 on the gang beam 12 for fastening the wing 38 in a transporting position by means of the member 110; the bracket 121 has an opening large enough to receive the cam 112 and a slot for passage of the retaining pin 114.
Patent GB-652988-A (GB)
Title: Improvements in and relating to the production of artificial protein threads, filaments and the like
IPC: D01F4/00
Filed: 1948-12-24
Abstract: Protein threads, formed by extrusion of a solution of a protein through a jet into a setting medium and treatment in one or more aqueous baths containing formaldehyde, are treated with an aqueous solution in which is dissolved a halogen-substituted aldehyde, so that the protein is softened and the thread becomes elastic, and then stretched at least 50 per cent while they are still elastic. Typical proteins are lactic casein, soya bean and peanut proteins. The preferred halogen-substituted aldehyde is chloral (used as its hydrate) and other suitable compounds are bromal, monochloracetaldehyde, dichloracetaldehyde, 1 : 1-dibromopropionaldehyde and other water-soluble halogen-substituted propionaldehydes.  The aqueous solution containing the halogen-substituted aldehyde preferably contains a salt or salts such as aluminium acetate, calcium chloride, magnesium sulphate or sodium sulphate, and also may contain a hardening agent such as formaldehyde.  It may also be heated, if desired, to temperatures up to boiling.  The thread may be stretched during its passage through or after removal from the halogen-substituted aldehyde bath.  The time of treatment should be from 30 minutes to 2 hours or more.  In using chloral the concentration should be from 5 to 100 grams of chloral per litre of solution.  The elastic condition lasts long enough to permit the thread to be washed with water to remove excess chloral before being stretched.  Stretching may be from 50 to 400 per cent and may be carried out at ordinary temperatures or temperatures up to 100 DEG  C.  The treatment may be carried out at any suitable stage after the initial setting and either before, during or after formaldehydeinsolubilizing.  It is preferred to harden the threads preliminarily, stretch them and harden again without allowing contraction first.  In an example a 20 per cent aqueous solution of peanut protein containing 0.5 per cent free caustic soda is extruded into a bath containing 10 grams sulphuric acid, 10 grams formaldehyde and 400 grams sodium sulphate per litre at 40 DEG  C.  After preliminary hardening, the tow of filaments is stretched 550 per cent and further hardened without contraction. It is then immersed for 2 hours in a solution at 50 DEG  C. of 50 grams chloral hydrate and 380 grams sodium sulphate per litre.  It is then water washed and stretched 100 per cent at ordinary temperatures, and finally hardened for 2 hours in a bath containing 10 grams formaldehyde and 400 grams sodium sulphate per litre at 50 DEG  C. washed with water and dried.
