Title: Improvements in or relating to machines for measuring and marking fabrics
IPC: D06H1/02
Filed: 1922-01-19
Abstract: 196,358. Casperson, A. M. Jan. 19, 1922. Transferring designs.-A machine for measuring and marking fabric as it is drawn over a flat table 13 by the rotation of a measuring roller 11 and a nip roller 12 is provided with marking means mounted on a carriage 24, 25 which is reciprocated over the fabric by a chain 28 driven from the roller 11 so that the marker moves at the same linear speed as the fabric at the instant of pressing. The measuring-roller 11, which is driven by gearing 20, 19, 18 from a hand or power driven shaft 14, is geared to a sprocket 30 driving a chain 28 connected to the marking-carriage by a link 27. The carriage comprises an upper part 24 running on rails 23, and a vertically movable lower part 25, which carries spools 48 of transfer paper bearing the desired marks, and is supported above the fabric by an electrically-heated iron 32 which hangs from a lever 38. The instant of marking is determined by a cam on the spindle 44, which permits a rod 42 supporting the lever 38 to drop and lower the lever about its pivot x, the constant fall of the iron 32 first releasing the carriage part 25 to bring the transfer paper on to the cloth and then pressing the mark. The feed of the transfer paper is effected by a rack 44<a> which engages fixed stops 46, 47, the rack driving a pinion 45 connected by a ratchet with t'he paperfeed roller.
Patent GB-1371878-A (GB)
Title: Firing weapon with a multi stage hydraulic mechanical braking of the forward movement of the barrel
IPC: F41A25/10
Filed: 1973-01-12
Abstract: 1371878 A firing weapon WERKZEUGMASCHINENFABRIK OERLIKONBUHRLE AG 12 Jan 1973 [18 Jan 1972] 1670/73 Heading F3C [Also in Division F2] In a firing weapon with a barrel member displaceable from a rest position into a working position, a multi-stage hydraulic-mechanical braking of the forward movement from the rest position of the barrel member is effected by an hydraulic brake having a cylinder 10 with a piston 13 therein, the latter having bores 22 formed therein, and by a mechanical brake which is connected in series with the hydraulic brake by a flange 30 of a sleeve 29 and has a set of springs 31 which are located in the cylinder 10. The bores 22 each have an end capable of being closed by a ring 27, thus forming a check valve, the ring 27 being urged by a spring 28 and having a protrusion 34 which is engageable with an end 36 of a sleeve 32 mounted in the cylinder 10 so as to limit the movement of the ring 27, and the bores 22 each have the other end 23 capable of being closed by a ring 24, which also forms a check valve, the ring 24 being urged by a spring 26. The latter is supported axially by a ring 25 and a spring 21 and the spring 28 is axially supported by the flange 30 of the sleeve 29, the flange 30 also being engageable by the springs 31. A sleeve 14 is displaceably mounted in the rod 12 of the piston 13 and is urged by a spring 17 and plugs 15, 16 are positioned at the respective ends of the piston rod 12. A slot 33 is formed in the sleeve 32 to allow fluid to flow from one side of the piston to the other side and is shaped as shown in Fig. 3 to ensure that the recoil force generated during firing of the weapon will be transmitted as a constant force to the gun mount. In operation the recoil of the barrel of the weapon causes the movement of the piston rod 12 against the force of the spring 21 so that fluid in the annular compartment formed between the piston rod 12 and the sleeve 32 flows through the slot 33 in the latter to the other side of the piston 13, the slot 33 being gradually closed by the piston 13 and the spring 21 being compressed to its limit. The ring 27 has moved into contact with the stop 36 and an intermediate compartment exists between the piston 13 and the ring 27 from which fluid flows into the bores 22. When the piston returns, the ring 24 is moved away from the piston by fluid passing through the bores 22 into the intermediate compartment. The impacting of the piston 13 against the ring 27 during the forward movement of the barrel of the weapon closes the bores 22 and the fluid flows through the slot 33 back to the annular compartment formed between the piston rod 12 and the sleeve 32, the gun barrel now being at its pre-firing position. Further forward movement of the gun barrel is damped by the springs 31, the ring 27 preventing escape of fluid through the slot 33.

Title: Process for extracting sulphur dioxide from gas which contains it
Inventor: MARCHEGUET HENRI GEORGES LOUIS
IPC: C01B17/60
Filed: 1960-01-18
Abstract: SO2 is recovered from gases by contacting with an aqueous solution of glyoxal at below 50 DEG C., e.g. 15 DEG -30 DEG C., and subsequently heating at above 50 DEG C., e.g. 65 DEG -75 DEG C.  The gas may contain 6-20% SO2 with air, CO2, HCl, SO3, or hydrocarbons.  The solution may contain 1-60% glyoxal and should be cooled during contact.  It is advantageous not to completely exhaust SO2 from the solution during heating and the process may be cyclic. 1,2-Dihydroxy-1,2-ethane disulphonic acid is stated to be formed in the solution and decomposed. Specification 891,421 is referred to.

Title: Improvements in or relating to folded sheets for maps, time-tables and the like
IPC: B42D15/00
Filed: 1934-01-19
Abstract: 425,788. Folding maps, diagrams, timetables, and the like. BONNAIRE, C., 19, Boscombe Road, Shepherd's Bush, London. Jan. 19, 1934, No. 1929. [Classes 16 and 146 (ii)] [See also Group XVIII] A map, diagram, time-table, or like sheet is folded into a number of strips and then folded transversely to the first folds, the second folding, at least, being a stepped folding so as to leave parts of each section exposed. In one form, Fig. 13, the map is given three parallel folds c, c<1>, c<11>, as shown and is then folded similarly along the lines b, b<1>, b<11> at right-angles to the folds c so as to give a stepped formation both horizontally and vertically. In order that any section of the folded map may be readily inspected by unfolding along the line c, Fig. 15, or the line c<11>, the map is slit along a portion of the line b<1>. Where more than three folds bare employed, it is necessary to slit every second fold b. Moreover, by slitting all the folds b and also the fold c, the resulting leaves can be stapled along the lines c, c<11> and opened in book fashion. Various other forms of folding are described in some of which both faces of the sheet are utilized. Tabs or incisions, offset from one another, may be formed on edges of the sheets to facilitate the turning- over of the leaves. Also, a press-fastener or other means, preferably used in conjunction with a cover member, may be provided for securing the sheets together normally. The sections may be creased along lines intermediate to the normal fold lines so that a smaller or larger part of the sheet may be inspected at a glance. A cover may be formed integrally with the sheet and thicker than the sheet by folding over and securing together parts of the sheet.

Patent GB-740625-A (GB)
Title: Method for the manufacture of polyesters of terephthalic acid
IPC: C08G63/78
Filed: 1953-01-23
Abstract: Polyethylene terephthalate is made by polycondensing a mixed ester of terephthalic acid wherein in one of the two carboxyl groups is esterified with ethylene glycol and the other with a lower monohydric alcohol, e.g. methyl, ethyl, n-propyl or iso-propyl alcohols.  The volatile monohydric alcohol split off during the condensation is removed.  Condensation is preferably performed in presence of a small amount of ethylene glycol and a re-esterification catalyst, e.g. sodium, magnesium, calcium or boron; sodium-, magnesium-, calcium-, zinc- or plumbous-oxides; or sodium-, magnesium- or calcium alcoholates.  The mixed esters are obtained by reacting a mono-alkyl ester of terephthalic acid with ethylene oxide (see Group IV (b)). In examples:  (1) a mixture of methyl - beta - hydroxy - ethyl - terephthalate, magnesium shavings and sodium dissolved in methanol is fused at 90 DEG  C. in a current of nitrogen and then heated to 260-270 DEG  C.  Pressure is then reduced to 0.5-0.2 mm. Hg and heating continued with stirring; (2) a mixture of ethyl-beta-hydroxyethyl-terephthalate, ethylene glycol, metallic sodium and plumbous oxide is heated first to 190-200 DEG  C. and then to 280 DEG  C.  Pressure is reduced to 0.2 mm. of Hg and the temperature maintained at 280 DEG  C. for some hours; (3) reaction is performed as in (2) but using the methyl ester and using zinc oxide instead of plumbous oxide. Specification 578,079 is referred to.ALSO:A mixed ester of terephthalic acid in which one carboxyl group is esterified with ethylene glycol and the other with a lower monohydric alcohol is made by reacting a mono-alkyl ester of terephthalic acid with ethylene oxide.  Reaction is performed in presence of a basic reacting substance, e.g. alkali metal hydroxide or carbonate, sodium acetate, sodium terephthalate, a tertiary amine or a quaternary ammonium compound.  Reaction is preferably performed in aqueous suspension at 50-120 DEG C., if desired under pressure. The mixed esters are polycondensed to polyethylene terephthalate (see Group IV(a)).
Patent GB-472459-A (GB)
Title: Improvements in or relating to synthesis of a thiazole compound and its salts
IPC: D06F1/08
Filed: 1936-03-17
Abstract: 4 - Methyl - 5 - b  - hydroxyethyl - thiazole is prepared by condensing thioformamide with a 3-halogen derivative of 3-acetopropan-1-ol.  The latter compounds may be prepared according to Specification 472,396.  According to the example, 3-brom-3-acetopropan-1-ol is allowed to stand with thioformamide in alcohol solution; the resulting hydrobromide is treated with an alkali to liberate the free thiazole, which may then be converted into its salts such as the sulphate and picrolonate.  By reaction with pyrimidine derivatives, products are formed which are analogous to the antineuritic vitamin.  The Specification as open to inspection under Sect. 91 also describes the synthesis of thiazoles by condensing compounds of the type CH3CO.CHXR, in which X is halogen and R represents the group CH2.CH2.OH or a group which may be converted into it, with compounds of the type ZCS.NH2, in which Z is hydrogen or a group such as amino and sulphydryl which can readily be transformed into hydrogen.  The Z group in the product of the formula <FORM:0472459/IV/1> may be converted into hydrogen when it is an amino group by treatment with nitrous acid and when it is a sulphydryl group by the action of an oxidizing agent such as nitric acid or hydrogen peroxide.  Similarly, the group R may be transformed into CH2.CH2OH by reduction when it consists of CH2.COOH, CH2.CHO or CH2.COOC2H5, and when it is CH2.CH2Y the group Y may be converted into hydroxyl by the reactions described above.  This subject-matter does not appear in the Specification as accepted.  Thioformamide is prepared by allowing formamide to stand in dry ethereal solution with phosphorus pentasulphide.

Title: Improvements in and relating to Hand Operated Digging Machines.
Inventor: BUSH JOSHUA JOSIAH
IPC: A01B13/00
Filed: 1918-02-16
Abstract: 123,371. Bush, J. J. Feb. 16, 1918. Diggers.-In a hand-operated digging-machine, a spade or fork is forced into the ground by sliding tread-engaging members carrying racks r which are adapted to be depressed by the engagement of the racks by teeth q on wheels p rotated by hand-levers O. Each hand-lever is adapted to enter any one of a series of holes in its wheel p. The rack members slide in frames t mounted on a barrow-like structure a provided with double separately pivoted wheels d and skids h, i. A second pair of wheels f may be fitted. To assist in forcing the spade into the ground, the operator can stand on counterbalanced boards k pivoted at m and arranged to engage the tread of the spade. When heavy soil is dealt with, a device for rocking the spade may be fitted. This comprises a link u<1> attached to the hand-lever 0 and to a lever v<1> y<1> pivoted on the frame at x and connected to a collar A on the spade shaft. In operation, after the spade has been forced into the ground, the collar A is detached and the spade shaft pulled down until it pivots about a block D. As the spade pivots to a horizontal position about the block D, shoulders E at the sides of the blade engage and slide upwards along angle-irons F. If the soil is to be examined, the spade is left in a horizontal position with its shoulders E engaging the horizontal upper extremities of the angle-irons and is locked in position by a catch on the block D and a loose rod which is adapted to pass under the shaft. In this position, the blade of the spade forms the bottom of a box, the sides of which are formed by sloping boards L on the frame. To remove the soil, the spade is pushed clear of the angle-irons and turned. The machine is moved along by using the spade as a lever to engage any fixed part. In a modification, the upper part of the angle-irons F is dispensed with. In another modification, the pinion wheels engaging the racks are mounted below the spades and capstan wheels for operating the pinion wheels are fitted outside the frame. In a further modification, two digging-implements are fitted on the same machine.
