Title: Process of improving retention of fillers and pigments by fibrous materials
IPC: D21H17/56
Filed: 1961-07-11
Abstract: Tertiary and quaternary derivatives of polyethylene imine used in the paper industry (see Division D2) are prepared by reacting polyethylene imine with alkylating or quaternizing agents. Specified agents are epichlorohydrin, alkylene oxides and formaldehyde which give hydroxyalkylated tertiary amino compounds which may be quaternized, and diazomethane, alkyl halides, dialkyl sulphates, alkyl phosphates and alkyl esters of p-toluene sulphonic acid.  The molecular weight of the polyethylene imine is between 200 and 1500, and in the products all the imino groups are converted to tertiary or quaternary groups.ALSO:The retention of filler material by paper pulp fibres is improved by adding to the aqueous pulp a polyethylene imine derivative in which all the imino groups are converted to tertiery or quaternary groups are converted to tertiery or quaternary groups by reaction with an alkylating or quaternizing agent respectively.  The compound may be added to the pulp in any order with the filler and may be added to the filler itself. Proportions of 0.005 to 0.5% based on the weight of dry fibres are suitable.  The pulp may contain size and alum.  Specified fillers are clay, titanium dioxide and calcium carbonate. Examples of alkylating and quarterizing agents are epichlorohydrin, ethylene oxide, dimethyl sulphate, formaldehyde, alkyl phosphates and alkyl esters of p-toluene sulphonic acid.

Title: Improvements in or relating to the production of soluble fertilizers from tricalcium phosphate
IPC: C05B13/02
Filed: 1933-09-11
Abstract: Phosphates are solubilized by heating them at 1200 DEG  C., with such quantities of alkali and silica that an alkali tricalcium phosphate is formed, and the free lime present is converted into a complex alkali calcium silicate.  Preferably the complex silicate approximates to a eutectic mixture.  In the case of sodium for instance its composition may be 72,5 CaO.Si O2 . 27,5 Na2O.Si O2.  An example of procedure is given.  The silica may be replaced by titanium oxide.

Title: Ball Cock.
Inventor: SCHOEPE ADOLD
IPC: F16K31/34
Filed: 1967-06-01
Abstract: 1,151,114. Valves. A. SCHOEPE, and F. E. SCHMUCK. 1 June, 1967 [23 June, 1966], No. 25229/67. Heading F2V. [Also in Division G3] A float valve, for maintaining the level of liquid in a container 24 such as a toilet flush tank comprises an inlet member secured to the tank and having parts 42, 48, 50 and 52, a easing member 54 surrounding the inlet member and having mounted at its top end the lower part 58 of a valve housing, this part having removably attached to it the valve housing upper part 80 which carries a guide 34 along which is movable a float (32) all parts except the inlet member which is metallic, being of plastics material, and all parts being held by the inlet member whose portion 52 is contained within a similar portion 56 of the lower housing part 58. Between the two housing portions there is held a resilient sealing member 82 comprising an outer stationary part 100, an intermediate movable part 96, and a central stationary part 92, the parts being interconnected by narrow flexible portions 98 and 94 with the intermediate portion 96 being movable towards and away from a seat 86 formed on the housing 58. A pin 84, formed with bands of varying diameters, some of which carry grooves, is movable within a bore formed in the central part 92, which bore communicates via radial openings (114) with a chamber 108. With the pin in the position shown, to which it is moved, via links 38, 36, by the float when in its uppermost position, fluid from the inlet member 42 passes, through the bore and radial openings, into chamber 108 thereby forcing part 96 on to its seating 86. With the float lowered, i.e. with the pin raised from the position shown, fluid flow to the chamber is stopped and fluid within this chamber is forced, by inlet fluid pressure acting on member 82, to the container 24 via opening 128 thereby permitting part 96 to rise from its seating. This then allows fluid from the inlet to flow across the seating 86, through apertures 60 and into chamber 70 from where it enters chamber 72, via axial passages (74), and hence, via circumferential passages 78, passes into the container 24. The disposition of the pin when in either of its two positions, together with the grooves formed on the pin, serve to substantially eliminate the ingress of solid material into the interior of chamber 108, any solid material contained in the liquid flowing from the inlet member, through apertures 60 and finally passage 78, being deposited in the casing member 54 from which it can be readily removed.

Inking-apparatus.-Inking-apparatus for franking-machines comprises a removable framework carrying a detachable casing containing an ink duct and a duct roller, and a reciprocating frame carrying an inking-roUer and connectable with a lever actuated from the driving-mechanism of the machine, the frame in its movement in one direction serving also to give a step-by-step rotation to the duct roller. The framework comprises two side-plates 5, Fig. 2, connected by cross-bars 6, Fig. 1, and rests within the casing 1 of the machine upon a plate 4 adjustable by means of screws 3 in relation to the rotary stamp 2. A channel-shaped casing 21 is removably supported in recesses in the side-plates 5, and contains a dismountable ink duct comprising a three-sided body 23, a sliding front wall 26, and a loading weight 29 resting upon the ink and closing the top of the duct. The duct is closed at the bottom by a duct roller 28 detachably mounted in the side walls of the casing 21. The duct rests on two pins 27 projecting from the rear wall of the casing 21, and is adjustable in relation to the duct roller bv means of two screws 30 in the rear wall. The inking-roller 9 is detachably mounted in the free ends of a bow-shaped frame 8 guided in grooves in the side-plates 5 and provided with a crossbar 10 for connection with a forked end of an arm 11 on a shaft 12, which is rocked by means of a cam plate 15 rotated by the driving-mechanism of the machine. A pin 16 on the cam plate 15 engages a second arm 13 on the shaft 12 to advance the frame 8, and the periphery of the plate 15 engages a roller 18 on the arm 11 to return the frame. The duct roller 28 is rotated by means of pawl-and-ratchet mechanism 31, 32, Fig. 3, having a variable throw. The pawl 23 has several teeth and is advanced by engagement of a lug 41 on the frame 8 with a depending projection 40 on the pawl, and returned by a spring 35. The initial position of the pawl, before contact of the lug 41, is determined by an adjustable stop arm 37 engaged by a lug 39 on a lever 33 attached to the rear end of the pawl. A messenger roller 43, Figs. 1 and 2, and a distributing- roller 19 are mounted in the side-plates 5. The roller 18 on the arms 11 normally lies in a notch 17 in the periphery of the plate 15 so that the inking-roller 9 is out of contact with the distributing-roller 19 when the machine is inoperative.
