Title: Apparatus for bending type levers or other levers for type-writing and similar machines
IPC: B41J7/24
Filed: 1928-12-20
Abstract: 302,925. Rheinische Metatllwaaren - und Maschinenfabrik S÷mmerda Akt.-Ges. Dec. 23, 1927, [Convention date]. Types.-In the formation of a bend in a typelever or the like, the type-lever is arranged between stationary jaws and is bent by means of an attached bar provided on the outer end with means for indicating the inclination of the bend and the correct position of the bend in the vertical plane. The apparatus shown in the Figure is provided with a clamp a for the type-lever f, and with a pair of jaws c, c<1> for engaging the type-lever near the bend, a bending-bar e provided with a handle h being secured by a clamp g<1>, g<2> to the end of the type-lever. The bending- bar is provided with a gauge i which is arranged within the arcuate rim b of the apparatus and carries a pointer k for reading graduations on the rim. The graduations extend to twenty-two on both sides of zero and indicate the different bends of a set of forty-five type-levers. The correct position of the bend in the vertical-plane is indicated when the gauge i is flush with the rim b. The type-lever after being bent is ready for assembly without further adjustment.

Abstract: 926,683. Stereoscopie microscopes; zoom lenses. COOKE, TROUGHTON & SIMMS Ltd. Oct. 20, 1961 [Nov. 2, 1960], No. 37724/60. Class 97 (1). A stereoscopic microscope has a reversible optical system of variable magnification between the objective and binocular eyepiece. Thus, as shown in Fig. 3, in the light path between the single objective 1 and twin relay lenses 5 are disposed twin telescopes consisting of lenses 2, 3 and 4, of which the lenses 2 and 3 are differentially movable and lens 4 is fixed. The magnification of each telescope can vary from 1 to M so that when the telescopes are reversed a further magnification range of 1/M to 1 is provided, giving a total range of 1 to M<SP>2</SP>. The lenses of each telescope are mounted between discs 14, Fig. 4, which are rotatable by thumbpieces 8 attached thereto, a spring detent arresting the rotation when the telescopes have been reversed end for end. Lenses 3 are carried by a saddle 21, Fig. 5, which is attached to a slider 17, this slider being movable along the microscope axis by a rack-and-pinion mechanism 15, 16 on operation of external knobs 9. Such movement of the slider 17 causes simultaneous movement of a saddle 25, carrying the lenses 2, through the medium of a cam 19 which is pivoted to the slider and is spring-pressed at 24 against the saddle 25.

Abstract: 523,454. Ball mills. PETERSEN, K. Dec. 29, 1938, No. 37775. [Class 59] In a mill for grinding refuse &c. comprising a sieve-like drum surrounded by a fine sieve which carries the non-siftable material to an elevating-device rotating with the drum, the elevating-device being provided with one or more inlet openings communicating with the fine screen and with one or more outlet openings, at least one passage in the elevating-device is provided with a movable member in the outlet opening whereby the direction in which the non- siftable material leaves the passage may be controlled. In Figs. 1, 2 longitudinal bars 29 fixed to end plates 1, 3 support grid bars 31 forming the mill drum. The grid bars may be spaced to vary the fineness of the screen and flat iron strips may be wound helically over the bars to strengthen the drum. An elevating device separates the drum into chambers 27, 37 and that in chamber 27 comprises side plates 45, 47 with transverse plates 51, 53 forming a passage 55 open at the bottom 57 to receive unsifted material from a conical or cylindrical fine sieve 33 and open at the top to both chambers 23, 25. V-shaped plates 63, 65 adjacent the top openings support a hinged rod 67 carrying a deflector plate 69, the rod being rotated by a handle 73 to turn the plate into a position whereby the material is diverted either into the chamber 23 or the chamber 25. The elevating device 37 is formed in a similar manner, the deflector plates 69 being operated through a sliding rod 89 and links 83, 85. The material passing through the outer screens 33 is discharged by plates 39 .on the perimeter of the drum. In a modification the inlet orifice 57 of the passage 55 may extend partly around the wall 45 and in another modification this inlet orifice may continue in a curve into the passage 55. The walls 45, 47 may diverge from the circumference to the centre so that the area of the inlet and discharge openings are equal. Specification 492,213 is referred to.

Title: Process and agents for stabilising aqueous emulsions of vinyl polymers
Inventor: PIROTTE EUGENE
IPC: C08L57/00
Filed: 1961-10-24
Abstract: Aqueous vinyl polymer emulsions are stabilized against coagulation in the presence of electrolytes by adding to said emulsions non-emulsifying nonionic agents which are condensation products of 5 to 35 mols. of ethylene oxide with one mol. of an aromatic hydroxy compound which is a naphthols or a xylenol.  The xylenols are defined as phenols bearing only two methyl groups on the nucleus.  The term vinyl polymers includes (a) homopolymers of compounds containing the CH2=C= radical, e.g. vinyl acetate, vinyl chloride, styrene, unsubstituted and substituted acrylic acid and derivatives thereof, e.g. amides, nitriles and esters with monovalent alcohols and (b) copolymers obtained from at least two vinyl monomers, e.g. vinyl acetatestyrene, vinyl acetate-vinyl chloride and ethyl acrylate styrene copolymers.  The ethylene oxide condensates are used in amounts of 0.25 to 10 gm. per 100 gm. of emulsion.  The emulsion may also contain at least one anionic emulsifier, e.g. ethylene oxide nonyl phenol condensates, alkali metal alkyl sulphates and alkali metal alkyl-aryl sulphonates.  The examples describe the stabilization of ethyl polyacrylate and polystyrene and copolymers of ethyl acrylate and methyl methacrylate or ethyl acrylate and styrene with condensates of betanaphthol with 11 or 21 moles of ethylene oxide and condensates of xylenol with 15 moles of ethylene oxide. The Specification also refers to to condensation products of 25 moles of ethylene oxide and 1 mol. of C16-C18 fatty alcohols.

[Class 65 (i).] The hinged door of a stove is provided with closing means including a lever and spring, together with means engaging the lever to neutralize'the effect of the spring automatically when the door is open and until it is manually closed. In the construction shown, a door 3 is hinged at the lower edge to the front of a broiling drawer 5, and closes the aperture in the stove front through which the drawer is withdrawn. To each side of the drawer is pivoted at 7 a lever 6 passing through a slot in a laterally-projecting member 13 at the front of the drawer, and connected at the other end to a spring 9. In the closed position of the door the spring exerts a direct pull upward through the lever 7 ; as the door is opened the lever is pulled through the slot, the bottom edge of which forms the fulcrum, until in the open position, Fig. 4, the fulcrum is close to the point of attachment of the spring, so diminishing the pull of the latter on the door. Lugs 12 on the levers 6 engage the members 13 to limit the opening of the door.
