Patent GB-451118-A (GB)
Title: Improvements in or relating to the preparation of baked cereal foodstuffs
IPC: A21D2/04
Filed: 1935-01-29
Abstract: Relates to a process for making hydrogen peroxide leavened cereal products wherein the mixed dough is, or may be, allowed to stand for a considerable time before baking and is then baked quickly, e.g. as in the production of waffles, griddle cakes and crackers.  The peroxide decomposition is inhibited during standing by adding an alkali to the dough which destroys the catalases, the inhibiting effect being destroyed by the raised temperatures during baking, at which temperatures the inorganic peroxide decomposition catalysts function, so that the leavening is effected quickly and is completed before the final baking temperature is attained.  Suittable inhibiting substances are alkali metal carbonates or bicarbonates and alkali-reacting phosphates.  Sodium hydroxide may be used with the carbonate or bicarbonate.  Alternatively, alkali metal hydroxides and alkaline earth metal hydroxides, or alkaline percompounds, e.g. alkali or alkaline earth metal peroxides, or alkali metal per-salts may be used.  A pH of 8 to 10 is mentioned as suitable for the dough, a pH of about 10 to 13 producing an undesirable taste in the final product.  The natural inorganic peroxide decomposition catalyst content of the dough may be increased by adding very small quantities of catalytic inorganic salts, salts of the heavy metals, e.g. soluble salts of copper, cobalt, iron or manganese, being suitable.  Recipes for making doughnuts are given in which sodium carbonate, and trisodium phosphate are used as inhibitors. Specification 433,471 is referred to.  The Specification as open to inspection under Sect. 91 states that the leavening may be effected by other per-compounds, e.g. various inorganic and organic peroxides, such as, sodium peroxide, urea peroxide, benzoyl peroxide; various per salts, e.g. perborates and percarbonates.  This subject-matter does not appear in the Specification as accepted.

Title: Processes for the production of aziridinoquinones
IPC: C07D203/14
Filed: 1956-01-31
Abstract: Aziridinoquinones are prepared by reacting aziridine or a C-alkylated aziridine with a 1,4-benzoquinone or 1,4-naphthaquinone having at least one alkoxy or alkylthio radical in a position adjacent to a nuclear carbonyl radical of the quinone.  The reaction is effected by stirring the reactants preferably in an inert solvent, e.g. methanol, ethanol, benzene, toluene, dioxane or petroleum ether, and at a temperature between 20 DEG  and 100 DEG  C.  Specified aziridines include aziridine and its 2-methyl- and 2,2-dimethyl derivatives, whilst suitable quinones are monoalkoxy-, mono-alkylthio-, 2,5-dialkoxy, 2,5-dialkylthio-, 2,3,5- and 2,3,6-trialkoxy and trialkylthio-, 2,3,5,6-tetraalkoxy and tetralkylthio-1,4-benzoquinones, and mono- and polyalkoxy and alkylthio-1,4-naphthaquinones, said alkoxy and alkylthio radicals containing at most five carbon atoms.  In examples: (1) and (2) tetramethoxy-1,4-benzoquinone and aziridine are refluxed in methanol, giving 3,6-dimethoxy - 2,5 - diaziridino - 1,4 - benzoquinone; (3) to (5) as in (1), tetra(ethylthio)-1,4-benzoquinone gives 3,6-di(ethylthio)-2,5-diaziridino-1,4-benzoquinone, 2,3 - dimethoxy - 1,4 - naphthaquinone yields 3-methoxy-2-aziridino-1,4-naphthaquinone, and 2,3-di(methylthio)-1,4-naphthaquinone gives 3-methylthio-2-aziridino1,4-naphthaquinone.  A number of "comparative examples" illustrate the use of phenoxysubstituted quinones under similar conditions; thus 2-phenoxy-, 2,5-diphenoxy-, 2,3,5,6-tetraphenoxy-, 3,6 - dichloro - 2,5 - diphenoxy-, 3,6-dibromo - 2,5 - diphenoxy and 3,6 - diphenoxy-2,5-dimethoxy-1,4-benzoquinone, yield 2,5-diaziridino - 1,4 - benzoquinone or its 3,6 - diphenoxy-, dichloro-, or dibromoderivatives; 2,3-diphenoxy- and 2,3-di(4-methylphenoxy)-1,4-naphthaquinone yield 3-phenoxy or -(4-methylphenoxy) - 2 - aziridino - 1,4 - naphthaquinone, and 2,5-diphenoxy-1,4-benzoquinone with 2-methylaziridine gives 2,5-di(2-methylaziridino) - 1,4 - benzoquinone.  Specifications 762,723 and 793,796 are referred to.

Title: Improvements in printing-machines for printing book-edges
IPC: B41F17/26
Filed: 1925-02-05
Abstract: 251,690. Tisdale, H. W., Hoskins, B. D. W., Firman, H., Bridges, F., and Codling, W. R. Feb. 5, 1925. Rotary machines. - The edges of bound books or blocks are printed on by a machine through which the books are passed in succession in two movements more or less at rightangles to each other. The book is placed in a vertical condition with its bound edge resting on an adjustable support 18<a>, and is carried by spaced rods on chains 9, 14 driven by bevel gearing 5, 6 towards a printing-roller 19. The covers of the book are controlled by spaced guides 16, 17, which converge su as to press the edges of the book together while being printed on by the roller 18. As the printed book leaves the guides 16, 17 it is acted on by a rotating pusher-arm 31 and passes on to a second runway 28 at right-angles to the first. It is turned through 90‹ and rests on one cover as it is propelled by push-rods 34 carried by chains 29, 30. The book is then carried past one or two vertical printing-rollers 35, 36 for printing on one or both of the remaining edges of the book, the roller 36 being laterally adjustable for dealing with books of different sizes. To maintain the drive of the roller 36 in all lateral positions it is driven by an idler gear at the joint of hinged links 46, 47. While the second printing takes place the top cover is pressed by rollers 40 on spring-pressed arms 39 so that the edges form a, solid face to receive the impression. The printed book is finally delivered by highspeed belts 41 which advance it relatively to the rods 34, so as to enable the chains 29, 30 to pass over their pulleys without interference between the rods 36 and the books. The books may be printed in several colours by providing more than one roller 19 &c. Tripping-arrangements; impression adjustments. - The printing-roller 19 and its inking- rollers are carried by a frame pivoted to the shaft 7 and the position of the roller is controlled by a set-screw, or set-screws, mounted in fixed arms on the main frame of the machine, against which the gravity-controlled frame rests. A feeler device 42 acts to stop the machine electrically if the book is fed the wrong way up, and trip levers 37 act in conjunction with the second printing-couple to trip the machine if the pages of the book are not flat. 'The drivers 37, 42 act to control switches of electrically-operated trip devices. Printing-surfaces.-The type is preferably cut in a rubber strip 50 vulcanized on a leather band 51 secured by screwed plates 52, 53 in a V-shaped recess in the roller. The part 43 of the roller 9 carrying the band 51 is raised so as to permit the passage of the boards or other backing of the book, which have slightly larger height than the pages of the book.

Title: Power operating tool for tensioning of binder strap
Inventor: CAVENEY JACK EDWARD
IPC: B65B13/18
Filed: 1966-01-25
Abstract: 1,094,022. Strap tightener. PANDUIT CORPORATION. Jan. 25, 1966, No. 3387/66. Heading F2G. The invention relates to a power-tool for tightening a binder-strap loop of the kind in which a connector is attached to one end of the strap and the other end is passed in a loop around a bundle and then inserted through a slot through the connector where there are means (not shown) to retain it. The tool comprises a housing 21 having an abutment at 28 for the strap connector during the tightening of the loop, a surface 53 co-operating with a gripper 60 urged by a spring (Fig. 12, not shown) towards the abutment surface and movable towards and away therefrom by a fluid motor connected at 22 to the housing 21 to pull the free end of the strap with respect to the connectar, a cutting mechanism for severing the free strap end between the abutment 28 and the gripper 64, a stop 180 to engage a surface 65 to cause the gripper to release the free strap end after cutting and fluid pressure acting through a port at 184 to eject the free cut strap end from the gripping assembly when the mechanism has returned it to the non-gripping position (as in Fig. 8) at the end of the operation. The gripping assembly is carried on the rod 93 of a piston 91 movable inside a pressure cylinder 81 connected at its ends to pistons 83 and 86 respectively. The cylinder 81 is surrounded by an annular space 88 to which pressure fluid can be admitted. The tool has an actuating handle 130 which is depressed to move a valve spool 122 to admit pressure fluid to the pistons through channels in the body of the tool so arranged to cause a series of operations to take place in predetermined sequence. First pressure fluid in between the pistons 83 and 91 causes the latter to move to the right (as in Fig. 8) to withdraw the gripper assembly, which is holding the free end of the strap, away from the abutment end 28, thereby tightening the loop in the strap. The same pressure also causes the piston 83 to move to the left against the force of a spring system 110, 111 which operates upon the piston 83 by way of the cylinder 81, the piston 86 and its rod 101. The piston 86 also moves to the left and with the piston 83 is driven more strongly to the left by pressure fluid which is subsequently admitted into the space behind it. The front of piston 83 then contacts a roller 158 on the end of a lever 153 pivoted at 154 causing a cutter blade 151 to rise and sever the strap end level with the abutment 28. The space between the pistons 83 and 91 is then vented causing the piston 91 to be driven to the left to return the gripping assembly, now freed of the severed strap end, back to its starting position. A knob 106 can be turned to adjust the effect of the spring system on the operation of the cutter so that the strap is severed only after a predetermined tension has been applied to it.
