Title: Improvements in or relating to the application of coatings to workpieces of sheet material
IPC: A43D25/18
Filed: 1943-04-22
Abstract: 567,005. Coating workpieces. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). April 22, 1943, No. 6450. [Class 95] A method of applying a liquid coating to a workpiece of sheet material which comprises (a) enveloping the workpiece between two sheets of substances which are impervious to the liquid, one of said sheets being flexible and having a plurality of separate capillary perforations, and (b) subjecting the enveloped workpiece to the action of the liquid in such manner that the liquid enters the said perforations and penetrates those adjacent to edges of the workpiece thus coating those edges. Fig. 4 represents a shoe upper part with a serrated edge S, at its rear margin. This edge is to be treated with a stain (or ink) without staining the remainder of the part. The shoe part enters along the feed table 48, Fig. 5, and is clamped between a shielding rubber member 24, and a perforated, non-absorbent rubber member 22. The work W, thus covers the upper ends of some of the perforations in 22, and seals them, causing air to be trapped therein. As the workpiece W passes between the presser roller 70 and an ink-carrying member 18, which consists of a resilient core 36 and an absorbent felt surface 38, dipping into the ink supplying vessel 20, the perforated member 22 is forced upwards around the workpiece W, causing ink to force its way into the space P, Fig. 12, and so coats the edges of the workpieces. Ink does not impinge on the lower surface 14 of W since the air seals prevent it, neither does it coat the upper surface 16, which is protected by the shield 24. The perforated member 22 and the shield 24 may be formed of endless belts and means may be provided for removing and cleaning 22 and also for washing ink from 24 and squeezing and brushing the surface dry. Specification 507,217 is referred to.

Title: Polymers of muconic acid and its esters
IPC: C08F36/04
Filed: 1964-02-17
Abstract: Polymers of muconic acid or esters thereof having a highly regular structure and 1,4-trans-enchainment are formed by polymerizing monomeric units. R1-OCO-CH=CH-CH=CH-COOR11 where R1 and R11 are the same or different and may be hydrogen atoms or alkyl radicals, substituted or not, having 1 to 8 carbon atoms, using as catalyst an organometallic compound of a Group I metal, preferably a lithium alkyl. Polymerization is generally carried out under an inert gas and in the presence of an anhydrous solvent e.g. a hydrocarbon or an ether.  The polymers have intrinsic viscosities of 0.30 to 0.50, 100 c.c./g. measured in chloroform at 30 DEG  C.  By saponifying the polymers salts of polyacids are obtained.  In the examples the monomers polymerized are diethyl muconate; di-isoproponyl muconate, and dimethyl muconate, the catalysts used being lithium-n-butyl; sodium iso-amyl; potassium-n-amyl; lithium phenyletherate and sodium n-octyl.  A polyacid salt is formed by treating poly-di-isopropyl muconate dissolved in toluene with potassium hydroxide in n-propyl alcohol, heating, adding water, distilling off the organic solvents and precipitating the polyacid with concentrated HCl.  The polymers of the invention may be (a) moulded, (b) extruded and (c) cross-linked by polymerization or copolymerization in the presence of a radical type catalyst; or by adding poly-alcohols or their oxides, preferably in the presence of a trans-esterification catalyst.

Title: Electric timepiece
IPC: G04C3/14
Filed: 1972-02-11
Abstract: 1377429 Electronic timepieces SUWA SEIKOSHA K K 11 Feb 1972 [3 March 1971] 6522/72 Heading G3T In an electric timepiece having a motor including a rotor 3 and a laminated stator 1, 2, 20, a lever 5 positioned between the stator and a base plate 30 prevents rotation of the rotor during setting. The stator carries a coil 17 which normally receives alternating pulses from a driving circuit 90 to advance the rotor in 60 degree steps. The rotor carries a three-lobed  member 4 and a driving pinion 14 which meshes with a fourth wheel 12 attached to a seconds hand. Pulling out a stem 7 for setting displaces a clutch wheel 10 by means of a yoke 16 so that a crown gear 10c thereon is moved to position 10b and engages the watch train. At the same time the lever 5 is allowed to rotate about pin 11 under the force of spring 6 to position 5b wherein lever end 5' makes electrical contact with a pin 9 while the other end of the lever engages the member 4 to stop the rotor. The rotor 3 and member 4 are so arranged as to ensure that the seconds hand is always stopped at zero or an even number of seconds. The pin 9 is connected to a reset circuit 100 which is thus turned ON to inhibit pulses to the coil 17. When the stem 7 is pushed in, a pulse is allowed to reach the coil immediately but has no effect because of the magnetic polarities of the stator and rotor; the next pulse advances the rotor by one step and the seconds hand by one second.

Title: Improvements in package delivery and counting mechanism
Inventor: LOCKWOOD JOSPEPH FLAWITH
IPC: B65G47/29
Filed: 1951-03-20
Abstract: 702,466. Counting-apparatus. SIMON (HOLDINGS), Ltd., H. Feb. 25, 1952 [March 20, 1951; July 16, 1951], Nos. 6632/51 and 16793/51. Class 106 (1). [Also in Group XXX] Means for spacing and counting packages travelling down a shoot (1) comprises a shoot section (3) of suitable size to support a single package, pivotally mounted and biased so as normally to occupy a position in which it can receive packages from the upper part of the shoot and capable of tilting under the weight of a package to a position in line with the lower part of the shoot to discharge the package to the lower part of the shoot, means (13) for obstructing travel of packages above the section (3) while it is in line with the shoot, and means (6) for locking the section in the package receiving position and for releasing it to discharge a package. When a package or sack S1, Fig. 5, is removed from the shoot 1 a lever 24 is rocked clockwise by a spring 40 and a cam member 35 tilts a two-way mercury switch 25 which completes the circuit of a solenoid 42. The solenoid 42 disengages locking means 6, allowing the weight of a second sack S2 to lower the hinged section or table 3 into alignment with the shoot ; the sack is then free to slide down to the lower position. While the table 3 is in this position a projecting part 44 prevents a subsequent sack (not shown) from sliding down; in a preferred embodiment fingers or sprags 13, Fig. 2, are projected through the surface of the shoot for this purpose. The movement of the table 3 operates, through ratchet means, a second cam member c causing a second two-way mercury switch 41 to be reversed as the table 3 is returned to the horizontal position by springs 5 or by counterweight 44. As the sack S2 falls on to the lever 24 it causes a pawl (not shown) to move over one tooth of a ratchet wheel 34, but the latter is not rotated until the sack is removed. When the circuit of solenoid 42 is completed, a second solenoid 43 in a parallel circuit is energized to operate a counter 45. This counter may be arranged to open a switch 46 in series with the solenoid 42 after a given number of sacks have been discharged. The table 3 is preferably shrouded by a hood 2 and each sack is brought to rest on the table 3 by a buffer plate 15 pivoted on a spindle 16 and backed by springs 21.

Title: Process for producing high purity rhenium and its compounds
IPC: C22B61/00
Filed: 1961-02-23
Abstract: Per-rhenic acid, containing cationic metal contaminants is purified by contacting an aqueous solution thereof with a cation exchanger in the hydrogen form and recovering per-rhenic acid pure from the effluent, the cations being retained by the cation exchanger. Rhenium values are converted to per-rhenic acid by combustion in oxygen, condensing the oxides, mainly rhenium heptoxide, lixiviating said sublimate with distilled water, filtering and subjecting the filtrate to contact with a bed of cation exchanger.  The effluent of purified per-rhenic acid may be neutralized with ammonia; ammonium per-rhenate may be crystallized and may be reduced by heating with hydrogen.  The metal may be used for manufacturing electronic components by powder metallurgy. The mother liquor from which ammonium per-rhenate has been recovered may be recirculated in the process by adding it to a further batch of rhenium values.  The cation exchanger may be regenerated by contact with a non-oxidizing mineral acid, e.g. 12% hydrochloric acid.  The examples relate to the removal of impurities which include potassium, iron, copper, magnesium and aluminium ions; alkali and alkaline earth metal ions may also be removed by the process.
