Abstract: 729,552. Reservoir pens. WATERMAN CO., L. E. Jan. 3, 1952 [March 29, 1951], No. 263/52. Class 146(3). In a reservoir pen one end of the feed-bar is arranged for fitting within the base of a feed section and an ink feed groove extends longitudinally along the top of the feed-bar for conducting ink from an ink reservoir to the point of a pen nib, the feed-bar being provided with side pockets extending along the top of each side of the ink feed groove, a series of ladder cuts extending along at least the major portions of those parts of the sides of the feed-bar that lie beyond the feed section, thus forming capillary passageways extendihg transversely of the feedbar, and at least one back groove defined by longitudinal side walls extending along the bottom of the feed-bar from the tip to a point within the feed section. As shown, a substantially cylindrical feed-bar 20, Figs. 1 and 2, has an ink feed groove 23 provided with fissures 24, side pockets 32 and a back groove 39. Transverse capillary passageways 33 are cut in the side walls of the pockets, the passageways 33 being separated from each other by partitions 35 and 36 and separated from the groove 23 by walls 34. The passageways 33 open at their lower ends into an enlarged opening 40, Fig. 5, leading to the back groove 39. During writing tmder normal conditions, ink is drawn by capillary attraction from the ink reservoir, not shown, through the fissures 24, Figs. 1 and 2, to the nib, not shown, while air to replace the ink used passes through the groove 23 to the ink reservoir. Ink in excess of that required for writing passes through channels 37 and the passageways 33 into the pockets 32 and groove 39 which serve as ink overflow compartments. The groove 39, passageways 33, fissures 24, and groove 23 are so dimensioned that overflowing ink is used from the. groove 39 and passageways 33 before further ink is drawn from the reservoir through the fissures 24. In modifications, the enlarged opening 40 may be a flat recess (Fig. 6, not shown) or the feed-bar may be flattened (Fig. 7, not shown). In a further modification (Fig. 13, not shown), two back grooves are provided, thus increasing the ink overflow space available.

Patent GB-436204-A (GB)
Title: A method of improving the physical and mechanical properties of metals and alloys
IPC: C22B9/10
Filed: 1934-01-04
Abstract: The mechanical properties of metals, e.g. copper, nickel, and their alloys and particularly those produced by the melting of scrap metal, are improved by removal of the gaseous impurities, e.g. hydrogen, sulphur dioxide, carbon monoxide, cyanide compounds, nitrogen, &c., by creating neutral or reducing conditions in the bath by using a neutral or reducing atmosphere when the metals are first melted and then rendering the atmosphere oxidizing and adding to the bath one or more oxidizing agents in a quantity substantially equal to that theoretically necessary to oxidize the gaseous impurities, the oxidation taking place in the presence of a slag containing one or more compounds of barium or strontium and in the presence of a substance or substances less noble than the principal metal of the bath.  The less noble substance or substances may be a constituent of the bath, e.g. zinc in the treatment of brasses and bronzes, or may be added thereto.  Substances such as zinc, cadmium, iron, manganese, sodium, and phosphorus may be used.  The oxidizing agent must not be one, such as a chlorate, a perchlorate, or borax, which is decomposed at the temperature of the bath and is preferably a metal oxide, e.g. copper oxide, zinc oxide, nickel oxide, or manganese oxide.  The slag comprises a compound of barium or strontium, which is preferably the carbonate but may be the fluoride, chloride, nitride, oxide, or peroxide, preferably mixed with a substance to lower the melting point, e.g. sodium carbonate, potassium carbonate, borax, sodium or potassium fluoride, or calcium fluoride.  When the metal or alloy contains sulphur, does not contain a desulphurizing element such as tin or zinc, and is a ready solvent for sulphur dioxide the sulphur is removed prior to the oxidation by treating the metal in a reducing atmosphere with a slag containing a compound of barium, preferably the carbonate, an alkali metal carbonate, and wood charcoal, the slag containing the absorbed sulphides being skimmed off before the oxidation.  In treating nickel, barium peroxide is added to the slag in the oxidizing treatment to convert the sulphides into barium sulphate.  After oxidation is complete a small proportion of phosphorus or phosphorus and magnesium may be added to compensate for the introduction of oxygen during casting and in treating a copper-nickel alloy a small amount of manganese may be added after oxidation and before casting as an alloying ingredient.  Reference is made to the treatment of alloys containing specified amounts of copper and tin; copper, and nickel; copper, tin, and zinc; copper, tin zinc, and lead; copper, tin, zinc, lead, antimony, and iron; and copper, tin, lead and iron.  Specifications 421,904 and 429,440 are referred to.

Abstract: 456,621. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., Aden Road, Ponders End, Middlesex.-(Maatschappij van Berkel's Patent Naamlooze Vennootschap ; 33, Boezemsingel, Rotterdam, Holland) Jan. 7, 1936, No. 537. [Class 28 (ii)] In a slicing-machine having a slice-thickness determining gauge plate or fence and a ratchetoperated mechanical feed, the regulating-cam or shroud for the ratchet mechanism is operatively connected with the gauge plate so that it is adjusted with the gauge plate by the manipulation of a single controller. As shown, the feed ratchet is operated by the contact of the arm 19<2> with a fixed stop 20, and the regulating-cam is carried on a pinion meshing with a rack 23 which is normally stationary on the carriage 11 but is slidably adjustable by a depending member 25 contacting with the upright parts 26, 27 of a bar 28 which is itself slidably adjustable on the base 10. The gauge plate 15 is mounted on a rod 30 slidable in bearings in the base 10 and urged by a spring 31, which bears against the collar 32, into the maximum slice thickness position. The slice thickness controlling handle 40 moves over a scale 42 and is part of a lever 33 which is connected at its pivot to a cam 35 which actuates a bell-crank 36 to press the gauge plate 15 to the smaller slice thickness positions against the action of the spring 31. The end of the lever 33 remote from the handle 40 is forked to engage a pin 39 on the sliding bar 28 which is thus adjusted in accordance with the setting of the gauge plate and effects a corresponding adjustment of the rack 23 and regulating cam during the first reciprocation of the carriage 11. In a modification, the ratchet is operated by a roller on the connecting-rod 50 engaging and rocking a lever pivoted at one end to the base and being connected, at the other end, by a chain to a chain wheel secured to the pawlcarrying lever. The return of the chain &c. is effected by a torsion spring attached to the pawl carrier. The ratchet wheel is connected by gearing to the feed screw. The pawl is arranged, in known manner for silent operation, and the hand wheel for re-positioning the feed table is pressed inwards to be effective, this action lifting the pawl from the ratchet teeth.

Title: Improvements in and relating to control gear for aircraft
IPC: B64C13/00
Filed: 1929-01-09
Abstract: 304,129. Junkers, H. Jan. 14, 1928, [Convention date]. Controlling.-In aircraft control gear of the type having a fin and a rudder closely disposed in the rear thereof, a. lever is attached to the rudder and a point on the lever is guided along a definite path in such a manner that a given deflection of the fin causes a corresponding deflection of the rudder in the same direction but through a wider angle. The mid position of the gear and the transmission ratio between the fin and rudder may be varied during flight. In the form shown in Fig. 1, a fin 1 is pivoted, at 3 and carries a rudder 2 pivoted at 4. The end 13 of a lever 12 mounted on the rudder is guided in a fixed slot 14. Alternatively the rudder 2 may be carried by an arm hinged at a point on the median line of the fin in front of the fin pivot 3, and an inward extension of this arm may be guided in a slot located between the pivots of the rudder and fin and in the midship plane of the controls. In a further modification the rudder 2 is hinged to the trailing edge of the fin and is provided with a toothed quadrant of which the axis coincides with the pivotal point 4. This quadrant gears with a second stationary quadrant of which the axis coincides with that of the fin. Further forms wherein the desired movement of the rudder is obtained from the fin through offset levers connected to the fin or to levers or links attached thereto and to a lever offset from the rudder lever, are also described. Means are described for varying the mean position of the rudder or for modifying the transmission ratio by displacing the pivots or varying the effective length of the links. According to modifications described in the Specification as open to inspection under Sect. 91 (3) (a) a lever 12, Fig. 2 (Cancelled), attached to the rudder 2, which is hinged at 4 to the rear edge of the fin 1, is pivoted at 13 to the outer end of a rod 15 pivoted at a fixed point 16. In Fig. 3 (Cancelled), a point 23 on a lever 22 attached to the rudder 2 is guided on a line A by being attached to a rod 25 pivoted at 26. Fig. 3<a> (Cancelled) shows means for adjusting the midship position of the steering-gear consisting of a bell-crank lever 29, 26<1> pivoted at 30 and attached to the lower end of a rod 25, and by a link 36 to an adjusting-nut 37 carried by a screw 38, respectively. In another form similar to that of Fig. 3, a slot in a lever attached to the rudder may be engaged by a fixed pin on the line A. Alternatively the rudder and fin are hinged at fixed points and the fin is linked to the rudder lever. In a modification of the toothed quadrant arrangement described above, fixed and movable segments are used connected by crossed bands. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to the operation of electrical circuit breakers
IPC: H02H7/22
Filed: 1924-01-11
Abstract: 230,216. Gifford, R. D., and Nalder Bros. & Thompson, Ltd. Jan. 11, 1924. Cut-out arrangements; automatic circuit - breakers. - In means for protecting local feeder or branch circuit circuitbreakers on an overload in the local feeder, a relay therein energizes a clock-work or other independent, adjustable timelag device for tripping its circuit - breaker and each local breaker is provided further with a second relay arranged, on abnormal overloads, to ensure that the main breaker will open and, by stopping the time-lag mechanism, t h a t the operation of the local breaker will be prevented. In Fig. 1, the main feeders 1 - - 3 have current transformers 4 - - 6 and an overload relay 17 operating the main bre,aker 18 on normal overloads. The local feeders 13 - - 15 have. current transformers 10 - - 12, in circuit with each of which are an overload relay 19 and a second relay 20 in series or parallel with it. When an overload in a local feeder causes the contact 21 of the corresponding relay 19 to close, a circuit will be made from a separate source 22, 23 preferably of direct current, through lead 27, closed contacts 21, 24 and an electromagnetic device 25, which operates the time-lag for opening the local circuit-breaker 26. When the time-lag has operated, this opening circuit is made by way of contacts 30. Fig. 3 shows a clock-work time-lag wherein the armature of the operating coil 33 of the device 25 releases, by means not shown, a disc 34 carrying an arm 35 which engages after a predetermined time a latch 43 and allows a spring 44 to bring together contacts 45, 46. The lag is adjustable by pivoting the arm 35 at 36 and securing it by a screw 37 in one of a number of holes 38 in the disc. If the overload becomes abnormal, any or all the relays 20 will open contacts 24 and de-energize the coil 33, thus stopping the clock-work before the contact 20 is closed and allowing the main breaker 18 to deal with the overload. In Fig. 2, the arrangement is modified by the relays 20 closing the contacts 47 and establishing a tripping circuit for, the main breaker 18 by way of leads 48, 49, the transformers 4 - - 6 and relay 17 being included in order to deal with overloads in parts of the circuit other than the local feeders.
