Title: Improvements in a variable spacing typewriter
IPC: B41J33/36
Filed: 1966-06-03
Abstract: 1,148,922. Ink-ribbon mechanisms. ING. C. OLIVETTI & C., S.p.A. 3 June, 1966 [9 June, 1965], No. 24850/66. Heading B6F. Variable ribbon feeding arrangements.-A variable letterspacing typewriter in which a type action interposer 3 has an abutment 27 which co-operates with a letter spacing bail 24, is provided with an ink ribbon mechanism having two slides 51, 58 the first of which is operated to advance the ink ribbon 28 through two to four unit spaces and the second of which, in conjunction with the first slide, is moved to advance the ribbon through five unit spaces, thereby the second slide 58 advances the ribbon prior to impression and the first slide 51 advances the ribbon after the impression. In operation following depression of a type key the abutmeat 27 of the interposer 3 is placed opposite the bail 24, which when the letter spacing does not exceed four units, prevents displacement of a link 23 and the ink ribbon is advanced by feed rollers 33, 34 by an amount corresponding to two tooth spaces of a ratchet wheel 47 which is driven by pawl 49 of a slide 51. The slide is oscillated by the arm 54 first rearwardly and then forwardly to drive the ratchet wheel 47 during the forward movement. During the rearward movement the second slide 58 is disabled by a lug 67 which arrests a lug 64 on the slide 58 which is provided with a slot 60 to enable the arm 54 to execute a lost motion. When the bail 24 is arrested by abutment 27 on the interposer 3 which corresponds to five letter spacing units the pivotal movement of bail 24 displaces a link 23 so that a lug 69 on cam follower 22 is placed under the lug 68 of a pivoted lever 66 which is rocked clockwise to disable the lug 67 and remove it from the path of movement of slide 58. The latter when the bail 56 is rocked counterclockwise prior to impression drives the ratchet wheel 47 through its associated pawl 57, through one and a half tooth spaces and the slide 51 drives the ratchet wheel the same distance as before, the total distance corresponding to three tooth spaces of ratchet wheel 47. Brakes.-A take-up spool 31 is frictionally connected to a driving flange 40 secured to gear 41 which is mounted rotatably on shaft 42 and meshing with gear 43 which in turn is driven by a gear 44 attached to coupling 45. Stencil cutting arrangements.-For stencil cutting purposes the carbon transfer ribbon vibrator 29 which is articulated to a rocking arm 101, actuated by link 102, is disabled by a hand lever 95, which through link 92 rocks a bell crank 87 to place its lug 96 in the path of lug 97 on arm 98 fast with the rocking arm 101. Rocking of the bail 56 is prevented by a lug 81 on a lever 82 which arrests a lug 79 on the arm 78 of a bail 56 thereby disengaging the cam follower of lever 73 from the cam 77.

Abstract: 504,177. Attaching fittings to glassware. STEATIT MAGNESIA AKT.- GES. Sept. 13, 1937, No. 24935. Convention date, Sept. 12, 1936. [Class 56] [Also in Groups XL and V] In apparatus in which a ceramic part is fused directly to a glass part, such as electric discharge vessels, the ceramic has a porosity of between 10 and 40 per cent by volume. Such porous ceramics are easier to degas than dense ceramics and possess greater resistance to thermal stresses. The ceramic part may be provided with depressions or grid like perforations where the glass is fused to ensure a good seating. Glass walls may be stiffened by porous ceramic inserts fused in or on them. Where for electrical reasons it is necessary to employ bushes or tubes of densely-burned ceramic material, these are sealed into the porous part by glass' or glaze ; or a dense porous part may be provided with a porous ceramic part on the side facing the interior of the vessel, the porous part being sealed to the dense part by glass or directly to the glass wall. The porous ceramic material may be formed from a mixture of all three or any two of the oxides of magnesium, aluminium and silicon, particularly spinel (MgO, Al2O3) or similar mixed crystals. Magnesium oxide may be replaced by other alkaline earth oxides, and if the oxides are employed in the form of carbonates such as magnesite the carbon dioxide given off at burning temperatures of 1300-1400‹ C. increases the porosity. Clay material or magnesium or aluminium hydroxides may be added as plastifying agents. Silica, 20 per cent, or alkaline earths may be added to give a superficial coating to the individual grains; these constituents may also be added as hydroxides. Four examples of suitable mixes are given. The whole or a part of the mix may be pre-burned or pre-fused. Reference has been directed by the Comptroller to Specification 497,423.

Abstract: 207,915. Hall, J. M. Sept. 20, 1922. Moulds; stationary mould machines; feeding materials.-In moulding concrete building slabs of the type described in Specification 187,751, [Class 87 (i), Bricks &c.], the surplus moisture is removed from the material by providing the mould with a perforated bottom, which is capable of independent movement relative to the frame forming the mould sides and communicates with a series of chambers wherein a vacuum can be maintained. The mould a comprises a rectangular frame b supported on springs g which are mounted in guides rising from brackets f on a chamber e. The bottom of the mould consists of a perforated grid covered with fine gauze and supported on the hollow trunk c of a piston d slidably mounted in the chamber e. The latter is provided with passages p, p<1> which may be connected to an air pump J through a valve h. In operation, air is first exhausted through the passage p so as to withdraw moisture from the concrete in the mould. The vacuum is then destroyed and additional material added if necessary. A plate is then placed over the mould large enough to cover the sides b, and the air is again exhausted through the passage p, thus causing the mould and contents to be pressed downwards by the unbalanced atmospheric pressure. The hollow metal members n, for forming grouting- grooves, are then loosened from their supports, and the moulded blocks are ejected by placing the passage p<1> in connection with a vacuum and supplying air under pressure below the surface of the piston d. Concrete is fed to the mould from a sliding feed box, the bottom of which is formed of a series of parallel rotatable laths. The springs g may be replaced bv hydraulic rams. Specifications 14879/89 and 6751/14 also are referred to.

Filed: 1947-09-18
Abstract: 627,281. Hydraulic tappets. SAMUELSON, B. M. F. Sept. 18, 1947, No. 25481. [Class 80 (iii)] [Also in Group XXVII] A self-adjusting hydraulic engine-valve tappet has means for providing a controlled amount of lost-motion between the tappet and a valve stem actuated thereby so as to vary the amount of lift imparted whilst the engine is in operation. A tappet cylinder 1 with a closed end contacting the cam 2 has a plunger 3 contacting the valve stem 4 and loaded by a spring 9. Hydraulic fluid from a passage 7 and port 1a is trapped in the cylinder 1 between the plunger 3 and a ball-valve 8 for transmitting the cam lift to the valve. This fluid however can be controlled by means of an adjustable screwed sleeve 6 through a port 1b in the cylinder 1 to an outlet 10 so that lost-motion can be obtained between the tappet cylinder 1 and the plunger 3 until the port 1b is covered by the edge of sleeve 6. The amount of this lostmotion and the lift imparted to the valve is thus varied by the adjustment of sleeve 6 which may be actuated by hand or automatically by, for example, a governer.
