Title: Method for folding large area maps into the shape of a book and correspondingly folded maps
IPC: G09B29/04
Filed: 1961-06-27
Abstract: 951,695. Maps. G.FALK. June 27,1961 [July 13, 1960], No. 23166/61. Heading G5G. In making folded maps, certain of the fold lines are perforated prior to the folding operation, the perforating permitting mechanical folding of the map and subsequent unfolding of sections of the map by tearing along the perforated lines. In one form, the map which is first folded along line 13, Fig. 1, and then along lines 14 to form horizontal zones 1 . . . 4 and is finally zig-zag folded perpendicularly to lines 13,14 to form vertical fields 5 . . . 12, is provided during printing with perforated lines 15, 16, 17 between the lines 14 and at alternate zig-zag folds. The perforations allow trapped air to escape during folding, and can be torn after folding as shown at 15, Fig. 5 to allow sections of the map to be inspected without unfolding all the map. The zones 2,1 may be progressively wider vertically than the zones 3, 4 so as to provide visible strips along the top edge upon which information may be printed. In another form wherein the map occupies both faces of the sheet upon which it is printed, the sheet comprises only the two zones 1, 2 with perforated lines 15, 16, 17 as shown i.e. extending between fold 14 and lower edge 13.

Title: Method of making metal bodies from metal powder
IPC: C22C33/02
Filed: 1947-08-22
Abstract: 636,921. Powder metallurgy. ISTHMIAN METALS, Inc. Aug. 22, 1947, No. 23331. Convention date, May 15, 1945. Drawings to Specification. [Class 83 (iv)] Working at specifced temperatures. - An accurately dimensioned steel article is made by forming a compact of approximately the shape and size required from a mixture predominantly of iron and steel powders, heating the compact to above the critical temperature to convert it to the austenitic state, quenching it to a subcritical temperature and then pressing it to the required final form while still in a temporarily stable austenitic state and finally allowing it to cool to a normal temperature. In a preferred method, the powder is mixed with a lubricant such as stearic acid and cold pressed to a density of about 7. The compact is then heated in a non-oxidizing atmosphere to between 700‹ and 1100‹ F. to drive off the lubricant and is then heated to above the critical temperature for the particular steel in order to transform it into austenite and to allow the diffusion of any alloy constituents that may be present. The compact is then quenched to a temperature below its critical temperature but above the Ar<SP>11</SP> range so that it remains in a temporarily stable austenitic state and before it has had time to transform, it is pressed at 60 to 90 tons per square inch to its final required shape and size. The quenching and pressing may be combined by using relatively massive dies. After this the austenite is transformed to a stable form such as bainite or mortensite, according to the manner of cooling. In one example, electrolytic iron powder is mixed with 1 per cent manganese, 0.9 per cent carbon and 1 per cent stearic acid, compacted at 25 tons per square inch, sintered in hydrogen at 2000‹ F. for three hours and then quenched in molten solder at 500<SP>o</SP> F. Within two minutes the compact is pressed between dies at 90 tons per square inch to final form and rapidly cooled to transform the austenite into mortensite. Alternatively the article may be slowly cooled to produce a pearlitic structure. In another example, steel powder including 0.75-0.88 per cent carbon, 0.60-0.90 per cent manganese, 0.04 per cent maximum phosphorus and 0.05 per cent maximum sulphur, the remainder being iron, is mixed with 1 per cent stearic acid and compacted. It is then sintered in an atmosphere of hydrogen and methane at between 1500- 2400‹ F., quenched in mercury at 520‹ F., pressed to final form at 90 tons per square inch and cooled.

Title: Improvements in and relating to step-by-step electric motors
IPC: H02K37/00
Filed: 1949-09-13
Abstract: 687,199. Electric motors. COSSOR, Ltd., A. C., WILLIAMS, B. C. FLEMING-, and WOODWARD, C. R. Aug. 28, 1950 [Sept. 13, 1949], No. 23646/49. Class 35. In a step-by-step motor, which may be supplied with A.C. or current impulses, the stator and rotor have unequal numbers of salient poles, the poles on one member being larger in the circumferential direction than those on the other and the poles on one member are alternately energized to produce rotation. In one form, Fig. 1, the rotor has ten narrow poles 17 and the stator has four broader poles 11, 12, 13, 14 which are offset from the diametric positions relative to the rotor spindle in a direction opposite to the rotor's rotation. This has the effect of making their pole-faces tangential to the path of the rotor pole ends at one side. The stator poles carry windings 18, 19, 21, 23 energized by impulses or A.C. supplied to terminals 24, 25, whilst the stator poles 12, 14 carry additional windings 20, 22 fed with continuous current from terminals 26, 27. In the absence of an impulse, the steady excitation of poles 12, 14 causes the rotor to rest in the position presenting the shortest air-gap, as shown. When a current impulse is supplied to terminals 24, 25, poles 11, 13 become magnetized and the magnetic effects are so proportioned that poles 12, 14 are demagnetized. The faces of poles 11, 13 being tangential to the path of the rotor poles, attract the nearest poles and the rotor turns in direction 28 to the position of least air-gap. When the impulse ceases, the poles 11,13 are demagnetized and poles 12, 14 become remagnetized, thus causing the rotor to complete the step of a complete pole-pitch. In a modification, the stator has only two poles disposed at right angles, the flux being returned through the rotor shaft. In a further modification, the rotor has three equally spaced narrow teeth while the stator carries a pair of poles spaced by 60 degrees so that each current impulse produces 120 degrees rotation. In a modification of this form, the rotor teeth are polarized as north poles while the stator poles each carry two windings. The continuous energization makes one north and the other south and the impulses reverse this magnetization to produce 120 degrees rotation as before. Fig. 3 shows a form in which the rotor poles carry impulse energized windings 18, 21 and a continuously energized winding 20 fed through slip rings. The stator carries ten teeth and each impulse produces a movement of one tooth pitch as before the flux being returned through the shaft. The rotor shaft may carry a brake for high-speed operation.

Filed: 1931-08-24
Abstract: 378,213. Turning sacks inside out. FOLKER, J. K. and TRUELSEN, F. F., (trading as FOLKER & TRUELSEN), 88, Aarhusgade, Copenhagen. Aug. 24, 1931, No. 23725. Convention date, Feb. 13. [Class 112.] A sack or bag to be turned inside out is placed on a table 82 with its open end under a suction pipe 53, and a lever 52, which carries the pipe 53 and which is actuated by a rod 57, is at the commencement of the cycle of operations lowered to engage the sack. A suction pump 56 acting through the pipe 53 and through a pipe 83 having ports in the table 82, opens the sack mouth. The lever 52 then rises and a reciprocating slide 40 is moved, by a rod 41 along guides 39, to move a pair of spring-pressed grippers 46 carried thereby into the open mouth of the sack and engage the sides. A frame 2, adapted to be oscillated by a transverse rock shaft 8 through links 9, 11, 12 from a cam 14 on a shaft 37 which is driven by gears 15, 16 from the main shaft 17, is swung upwards to register a portion at its free end having a rectangular aperture with the open mouth of the sack, which is then drawn, by the grippers 46, over the frame 2. The frame 2 is lowered to bring its open end opposite a member 19 which is reciprocated by a slide 21 to push the bottom of the sack through the opening in the end of the frame 2 and turn it inside out, spring-pressed side members on the frame 2 holding the sack extended. The top of the sack is released by the pull produced by the member 19 from the spring grippers 46 and the bottom is pushed between a pair of automatically opened and closed clamping jaws 64, 66 which close on it and hold the same while the frame 2 rises and the member 19 is withdrawn. The clamping jaws 64, 66 are then opened to drop the sack, now turned inside out, into a suitable collector.

Title: Improvements in or relating to film operated talking machines
IPC: G11B3/00
Filed: 1930-08-08
Abstract: 360,945. Sound-reproducing machines. HUGUENARD, E. A., 19, Rue Dupont de 1'Eure, Paris. Aug. 8, 1930, No. 23745. [Class 40 (ii).] Sound is reproduced from a grooved film record, by moving the fi1m in contact with a fixed member engaging the groove, whereby the film itself is caused to vibrate. The invention is shown as used in conjunction with means whereby the, vibrations of the film generate electric currents which effect sound reproduction. The film 1 passes over fixed guides 2, 3 and over a member 4 of polished, hard material such as agate, the part 4 being mounted on a flexible metal strip 5. A sapphire or like tool 6 is fixed on an adjustable arm 8, and engages the sound groove so as to vibrate the portion of film in contact with the member 4. Fixed between the strip 5 and the member 4 is the iron armature 14 of an electromagnet 12, the winding 13 of which is in circuit with an amplifier. Currents are thus induced by the vibrations imparted to the armature, and, through the amplifier, operate a loud-speaker or the like.

Patent GB-587258-A (GB)
Title: An improved manufacture of lubricating greases
Filed: 1944-11-29
Abstract: Lubricating grease is prepared by dissolving fats, fatty acids or naphthenic acids in mineral oil and saponifying them with a dispersion of metal oxide or hydroxide in an inert liquid.  The dispersion is one prepared by suspending the metal oxide or hydroxide in the inert liquid and mechanically comminuting till the particle size is predominantly 5m  or less.  Fats mentioned are mutton tallow and beef stearin while fatty acids mentioned are stearic acid, oleic acid, cottonseed oil fatty acids and synthetic fatty acids obtained by the oxidation of high molecular weight substantially saturated hydrocarbons such as paraffin wax. Mixtures of the saponifiable materials may be employed and lower fatty acids such as acetic or butyric acid may be incorporated with the saponifiable materials. The saponifying agent may be caustic soda, caustic potash, lithium hydroxide, calcium hydroxide, barium hydroxide, magnesium hydroxide, lead oxide (PbO), nickel oxide, cobalt oxide, or manganese oxide (MnO), but mixtures may also be employed.  The inert liquid in which the saponifying agent is suspended may be mineral oil but lighter fractions such as fuel oils, naphthas and more volatile products may be used.  If desired, the comminuted dispersion of saponifying agent in mineral oil may be diluted with an inert volatile diluent such as petroleum, naphtha of a liquefied gaseous hydrocarbon such as pentane, butane or propane, so that only the ultra-fine particles stay in suspension.  After settling or centrifuging, the volatile diluent is distilled off and the fractionated dispersion thus obtained used for saponification. Alternatively the original dispersion may be made in one of the inert volatile diluents mentioned above.  During comminution of the saponifying agent, a small amount of sodium stearate, sodium oleate, stearic acid, oleic acid or other similar soaps or fatty acids may be added to prevent coagulation or agglomeration of the finely divided particles.  The final grease may be put through a colloid mill and may be subjected to further cooking to evaporate moisture or to distil off glycerine resulting from the saponification reaction.  In examples, comminuted dispersions of caustic soda in mineral oil are heated with solutions of stearic acid, oleic acid, mutton tallow or cottonseed oil fatty acids in mineral oil to produce lubricating greases.
