Title: Improvements in sheet collecting and folding mechanism
IPC: B41F13/60
Filed: 1930-07-03
Abstract: 356,362. Paper-folding machines. GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A.-(Assignees of Crafts, C. S. ; 645, North Lombard Avenue, Oak Park, Illinois, U.S.A.) July 3, 1930, No. 20218. Convention date, Dec. 24, 1929. [Classes 100 (i) and 100 (ii).] In sheet cutting, collecting, and folding apparatus comprising a folding and collecting cylinder 10, Fig. 4, carrying folding devices co-operating with a pair of rollers 33, 34, each folding device consists of a single blade 41 which can be operated to engage the rollers 33, 34 at each revolution when the cylinder is not collecting and at intervals of two or more revolutions when the cylinder is collecting. As shown, the cylinder 10 is provided with three blades 41 with impaling pins 110 and sheet-supporting surfaces corresponding thereto. An arm 47, Fig. 2, is fixed to the shaft 37 of each blade 41 and carries rollers 48, 49 which run on a fixed track 53 during most of their travel and are engaged by slots 56, 57, 58 in a rotating cam-disc 55 so as to be rotated through 180‹ for each revolution of the cylinder in the usual way. As each shaft 37 only carries one blade 41, each blade thus engages the rollers 33, 34 for folding at alternate revolutions only, the pins 110 being correspondingly operated so as to collect two sheets before the blade operates. In order that each blade may be operated at every revolution, an additional rotating cam-disc 86 is provided and is carried by a shaft 83, Fig. 1, mounted in a bracket 73 slidable along the main frame 74 by means of a hand-lever 93 into position for engaging the rollers 48, 49. A part of the track 53 is cut away to allow of this, and the gap so formed is bridged when the disc 86 is moved to inoperative position by an arcuate guide-member 76 fixed to the slidable bracket 73. The pins 110 are operated by arms 113 carrying rollers 114 running in a grooved disc 116. A gear-wheel 123, Fig. 5, splined on the hub of the disc 116 can be engaged with a gear-wheel 129 on the shaft of the usual cutting cylinder 18 so as to drive the disc 116 at a speed ratio of 3 to 2 relatively to the cylinder 10 when sheets are to be collected. When the cylinder 10 is not collecting, the disc 116 is held stationary by sliding the gear 123 out of engagement with the gear 129 and into engagement with teeth on a fixed bracket 130.

Title: Bis (1-alkyl-1-carboxy-1-hydroxymethyl) phosphinic acids and method of producing same
IPC: C07F9/30
Filed: 1958-06-25
Abstract: The invention comprises bis(1-alkyl-1-carboxy-1-hydroxymethyl) phosphinic acids of formula:  <FORM:0867883/IV (b)/1> where R is C1-17 alkyl, their neutral alkali metal and alkaline earth metal salts and also their heavy metal complexes. They may be prepared by reacting a C3-19 a -keto-alkanoic acid with hypophosphorous acid, e.g. at 20-100 DEG C. in an acqueous or organic medium, or by reacting under anhydrous conditions, preferably in an inert solvent, e.g. at 0-25 DEG C. a C3-8 a -ketoalkanoic acid with phosphine in the presence of an acid catalyst and oxidising and hydrolysing the resulting phosphine condensate in the presence of an acid or alkaline aqueous oxidising agent.  Usually three molar proportions of the a -keto acid and one molar proportion of phosphine are used giving a condensate of formula:  <FORM:0867883/IV (b)/2> Specified oxidising agents are chromic acid, alkaline or acid permanganate and nitric acid.  Excess oxidising agent is preferably used at temperatures of 0-110 DEG C.  The reaction product may be neutralised with an alkali or alkaline earth metal basic compound.  The free acids and their alkali metal and alkaline earth metal salts act as sequestering agents forming soluble complexes over a wide range of pH with heavy metals, e.g. iron, nickel, cobalt, copper, uranium, thorium and palladium.  They may be used for extracting uranyl values from an ore.ALSO:Sequestering agents comprise bis (1-alkyl-1-carboxy-1-hydroxymethyl) phosphonic acids and neutral alkali metal and alkaline earth metal salts thereof of formula <FORM:0867883/I/1> where Y is hydrogen or an alkali or alkaline earth metal and R is C1-17 alkyl.  They are useful in the selective removal of heavy metals from mixtures containing ions such as nickel, cobalt, copper, iron, uranyl, thorium (N) and palladium in the presence of alkali and alkaline earth metal ions.  Thus ferric ion may be sequestered selectively from an alkaline solution containing both iron and calcium ions.  Iron chlorosis can be prevented or alleviated by treating an alkaline soil with a phosphinic acid derivative above to form a solubilised iron complex in preference to the calcium complex.

Title: Constant frequency electric generator
IPC: H02K19/38
Filed: 1960-06-10
Abstract: 889,518. A.C. generators; adjustable cores. HAMBURGER FLUGZEUGBAU G.m.b.H. June 10, 1960 [June 12, 1959], No. 20408/60. Class 35. An electrical generator unit for producing an output of constant frequency when driven at a variable speed comprises a rotor with two axially-spaced field windings 2a, 2b producing magnetic fields which are phose-displaced by 90 degrees in relation to one another and supplied with current at frequency <SP>#</SP>trans from an exciter E. The stator of main generetor H is provided with two armature windings 7a, 7b also relatively displaced through 90 degrees. The exciter rotor is rigidly attached to the main driving-shaft and so rotates at the variable speed # rot  while its field is rotated at the required output frequency <SP>#</SP>const. The rotating field may be produced by a permanent magnet " stator " 4 driven by a constant-speed drive HA, the exciter having a conical air-gap to permit regulation, or by an electromagnetic system fed by an auxiliary generator (Fig. 5, not shown) and producing a rotating field. In the latter case the exciter has two windings angularly displaced through 90 degrees, and the field windings of the main generator are not then phase displaced. The phase of the main output may be varied by rotating the exciter stator slightly. In either case the frequency of the excitation current supplied to the main generator field windings is <SP>#</SP>rot - <SP>#</SP>const. As the generator rotor rotates at frequency <SP>#</SP>rot the output frequency is therefore <SP>#</SP>const. A voltage regulator may be connected in the output circuit, feeding back to exciter E. A method of connecting two generator units together is also described (Fig. 6, not shown) employing a relay for interconnecting the output circuits when <SP>#</SP>rot exceeds a certain minimum, and a phase meter for equalizing the phases of the outputs. Specification 700,036 is referred to.

IPC: H01T2/02
Filed: 1954-07-16
Abstract: 781,378. Spark gaps. METROPOLITANVICKERS ELECTRICAL CO., Ltd. July 6, 1955 [July 16, 1954], No. 20823/54. Class 39(1). The centre electrode of a double spark gap is formed in two parts B1 and B2 connected together through a condenser C1 and resistor R3 and each part has an associated triggering electrode P 1  or P 2 . The parts B 1  and B 2  are connected to the mid-point of a potential divider R 1  R 2  which is connected between the outer electrodes A and C. A positive pulse generated at the mid-point of the potential divider by a pulse transformer T is applied between the coupling condenser C1 and the electrode P 2  causing breakdown of P 2  B 2  and then, as condenser C 1  charges up, P 1  B 1 . If C is positive with respect to A gap AB 1  breaks down followed by gap CB 2 . If C is negative with respect to A gap CB2 breaks down followed by gap AB 1 . The arrangement may be connected as a triggering device in the first stage of an impulse generator and ensures that when the generator polarity is reversed there is always an outer electrode which is negative with respect to the centre electrode and facing a triggering- electrode which is positive with respect to its associated electrode, which are the optimum conditions when triggering a spark gap. The spark-gap is designed to operate in still air at atmospheric pressure but may be enclosed in an envelope filled with gas at a pressure greater than atmospheric. Spark quenching means such as an air blast may also be provided. The centre electrode, Fig. 2, comprises two hemispheres 1, 2 for example of copper fitted with molybdenum inserts 3, 4 having central holes 5, 6 through which project molybdenum triggering rods 7, 8 held in brass bushings 9, 10 attached by screws, which are preferably staggered to prevent electrical breakdown, to an insulating disc 11 for example of ebonite to which the hemispheres 1, 2 are also attached. The triggering rods 7, 8 are surrounded by glass tubes 12, 13 which are ground at one end and fastened at the other end by wax to the brass bushings 9, 10. A resistor 14 and condenser 15 are connected inside the electrode so that only the two connections to the pulse transformer are brought out via channels in the disc 11. Specification 578,510 [Group XL] is referred to.
