Title: Apparatus for shortening a shoe lace whilst retaining the aglets
Inventor: LINDOW DAVID
IPC: A43C7/00
Filed: 2009-11-05
Abstract: A lace shortening device 1 comprises an oval housing 5 with a recess 6 in the underside. An internal wall 7 of recess 6 has conically shaped sides and holes 8A, 8B in the edge of the housing 5 communicate with recess 6. A method of shortening a shoe / boot lace while retaining the aglets 9A, 9B in place is disclosed. A portion is removed from the central part of the lace 2 between the aglets 9A, 9B and knots tied on both cut ends. The part laces are threaded through apertures 8A, 8B in the housing 5 to create a continuous, but shorter, lace. The shoe may now be re-laced with the housing located at a suitable point, usually midway between the first pair of eyelets. The device may also be used to lengthen a lace or to re-connected a broken lace.
Patent GB-626398-A (GB)
Title: Improvements in and relating to methods of preparing organogermanium halides
IPC: C07F7/00
Filed: 1947-04-15
Abstract: Organo-germanium halides are prepared by reacting heated germanium and a hydrocarbon halide which is preferably in the vapour state. Suitable hydrocarbon halides are alkyl and aryl chlorides or bromides such as methyl chloride, ethyl chloride, methyl bromide and chlorobenzene The germanium may be in the form of the metal itself, or an alloy with another metal, or may be intimately associated with a metal catalyst for the reaction, e.g. by forming an alloy. Suitable metallic catalysts are copper, silver, nickel, tin, antimony, manganese and titanium.  In examples, dimethyl germanium dichloride, methyl germanium trichloride and trimethyl germanium chloride and the corresponding bromides, diethyl germanium dichloride, ethyl germanium trichloride and diphenyl germanium dichloride are prepared.  The products may be hydrolysed to form the corresponding oxides.  Similarly, other organo-germanium halides may be prepared, e.g. alkyl germanium halides such as methyl, ethyl, propyl, butyl, amyl, isoamyl and hexyl germanium halides, aryl germanium halides such as phenyl germanium halides, aryl substituted aliphatic germanium halides such as benzyl and phenylethyl germanium halides, and aliphatic - substituted aryl germanium halides such as tolyl germanium halides.  Specification 575,667 is referred to.

Rolling - machines ; rotary - table, machines; stream-cutting machines. - A bon - bon moulding machine of the type wherein a pair of coacting cutter discs act upon a string of material is furnished with a mould disc disposed alongside one of the cutter discs and associated with a pair of rotary plunger holders furnished with plungers of which one set transfers the severed portions of material to the mould apertures and ejects the moulded sweets therefrom. As shown, the machine comprises a pair of cutter discs 18, 28 mounted on shafts 3, 11 connected by gears 8, 12. A moulding disc 19 is disposed alongside the disc 18 and co-operates with plungers 23, 24 carried by holders 20, 21 rigidly supported by the shaft 3.

Title: Improvements in apparatus for the mechanical production of foam
IPC: A62C5/00
Filed: 1934-04-06
Abstract: 422,672. Making foam; mixing- apparatus. SOC. DES AUTOMOBILES DELAHAYE, 10, Rue du Banquier, Paris. April 6, 1934, Nos. 10492 and 10493. Convention dates, April 6, 1933 and Oct. 2, 1933. [Class 47 (ii)] [See also Group II] A foam pump is combined, at its intake side, with a mixing-apparatus adapted to mix, and discharge to the pump, regulated quantities of water, air, and saponin solution, concentric passages provided for the several ingredients being such that an annular jet of saponin solution is sandwiched between two annular jets of air. The mixing apparatus delivers to the pump by the opening 2, in which is a valve 22 movable by a stem 25 to control the passage of water to the opening from a water conduit 6, 5. Water can also pass, by a port 8 controlled by a valve 44 on a stem 47, to a passage 9 connected to the opening 2 by an annular passage 9<a>. Saponin solution is admitted to the passage 9 by an inlet 14, 10 controlled by a valve 30 on a stem 34. Air entering at 38 is admitted, by a valve 36 on a stem 41, to a chamber 16 whence it passes to the opening 2 by annular passages 18, 21 provided respectively with oppositelyinclined vanes 70, 71. Thus, saponin solution mixed with water issues from the passage 9<a> between two layers of oppositely-gyrating air. The valves are all biassed normally by springs to closed position and may be separately controlled. As shown they are opened simultaneously by means of cams 54-57 carried by a shaft 52 and arranged to engage levers 58 .. 61 linked to the respective valve stems. The shaft 52 is rotated by a lever 55, so that all the valves are opened simultaneously to an extent determined by the profiling of the individual cams. Further, the shaft 52 may be slidable axially under control of a lever 64, some or all of the cams having a profile varying in an axial direction, so that by adjustment of the lever 64 the extent to which certain valves open may be adjusted. In a modification, Fig. 5, (not shown), all the valves are controlled simultaneously by a pivoted hand lever, and one of the valves is further controllable independently by a bell-crank lever pivoted to the said valve stem and to the hand lever. In another modification, Figs. 6 and 7, (not shown,) only the inlet port for the saponin solution is controlled by a valve, the quantities of the water and air admitted being controlled by the size of the water and air inlet and supply passages. The water supply conduit may include a gate valve and a pressure gauge. Specification 347,048 is referred to.

Title: Manufacture of acylated secondary alcohols
IPC: C07C67/03
Filed: 1942-08-05
Abstract: Vinyl esters of aliphatic monocarboxylic acids having less than five carbon atoms are reacted with alcohols having the formula R1R2CHOH, in which R1 is halogenmethyl, cyano, cyanomethyl or aldomethyl and R2 is alkyl or the same as R1 in the presence of a reaction medium containing sufficient alkali-metal salt or tertiary amine to give a pH greater than 7.0.  Examples of such secondary alcohols are: methyllactate, aldol, glycerol, diacetin, aldolcyanhydrin, lactonitrile and glycerol-a -d -dichlorhydrin and suitable catalysts are cyanides, silicates, carbonates and tetraborates of alkali metals, triethylamine and tributylamine.  In examples: (1) vinyl acetate is reacted with aldol, lactonitrile, diacetin and glycerol-a : d -dichlorhydrin; (2) vinylformate is reacted with lactonitrile; (3) vinylpropionate is reacted with lactonitrile; (4) methyllactate containing some potassium cyanide is circulated through a reservoir, a stainless steel coil immersed in a cooling bath and back to the reservoir while vinylacetate is slowly introduced.  The resulting ester of the secondary alcohol is usually recovered by distillation, the acetaldehyde simultaneously produced may be separated, however, by reacting with a compound which yields a product capable of removal by filtration or decantation.
