Title: Improvements in apparatus for shaping fan blades
Inventor: LURCOTT WINFRED NORTON
IPC: B21D53/78
Filed: 1950-08-29
Abstract: 706,018. Making fan blades. WING MANUFACTURING CO., L. J. Aug. 29, 1950, No. 21345/50. Classes 83 (2) and 83 (4) Stamping.-A press for shaping a sheet of metal into a hollow fan blade comprises a pair of separable dies pivoted to each other, a core to be lowered into position between the dies against the sheet of metal therebetween and means for moving the core and dies. The dies 36 and 38 are bolted to channel members 100, 102 of a press, Fig. 1, and are pivotably connected together by means of projecting apertured fingers 105, Fig. 5, cast integral with the dies. The press comprises a supporting frame 160, side members 164, an end member 174 bolted thereto and an end member 288 slidable on the frame under the action of nuts (not shown) threaded on rods 312 and rotatable by a chain 336 actuated by a hand-operated member. The channel 102 is pivotally connected by links 284 with the member 288 so that movement of the latter serves to adjust the relative positions of the dies. The weight of each channel 100, 102 is taken by springs 302, Fig. 5, surrounding rods 300 adjustably supported by means of cross members 294 resting in notches in racks 290 depending from the press frame. Channel 100 is connected by pivoted links 278 to a shaft 274 carried by arms 272 mounted on a shaft supported along the face of the end member 174. A fluid pressure cylinder 146 is coupled to the shaft 274 so that on admission of fluid thereto, the shaft will be depressed and the dies forced together. Core 34 is supported by arms 196, 198 from a shaft 194 at the ends of pivoted levers 190 and is so actuated through linkwork from another pressure cylinder 136 that the core may be lowered to a position between the dies. Compressed air is supplied from a pipe 110, Fig. 8, through a valve 112 which is first turned so that compressed air passes by pipe 130 to a dashpot 132 thereby forcing oil into the cylinder 136 to lower the core between the dies. As the core descends, an arm 154 connected with the coreoperating linkage opens a check valve 150 to allow compressed air to enter the cylinder 146 to effect the closing of the dies. In operation, a heated sheet of U or V shape is placed between the dies, the core moved into position and the dies brought together to press the sheet into the required form, the adjacent ends of the sheet then being welded at 32 to form the hollow blade 10, Fig. 11. Specification 706,076 is referred to.

Title: Improvements relating to the conservation or preservation of meat
IPC: A23B4/28
Filed: 1930-07-16
Abstract: 358,158. Preserving meat. SENTCHENKO, L., 7, Rue des Italiens, Paris. July 16, 1930, No. 21518. Convention date, Aug. 26, 1929. [Class 49.] Animal carcasses are preserved by injecting into the vessels of the slaughtered animal a preservative solution to replace the blood, the solution being injected into the left ventricle and the blood being withdrawn, substantially simultaneously, by suction from the right ventricle. A canula for use in injecting the solution consists of a tube 1 to the injection end of which a conical ferrule 3 is screwed adjacent to which is a piece of rubber 14 of cylindrical, spherical, &c. shape. An enlargement 13 of a tube 2 surrounding tube 1 bears on the other end of rubber 14, a metal washer 15 being interposed. A nut 6 which screws on tube 1 bears on an enlargement 10 at the rear end of tube 2, and is secured thereto by a spring pawl 7 which engages a notch 9 on enlargement 10 and is disengaged by depressing a push-rod 11. By screwing up nut 6 when the nozzle has been inserted in the left ventricle, the enlargement 13 presses on rubber 14 and decreases the length and increases the diameter of the rubber, thus making the canula fit. tightly in the aorta. To the rear end of tube 1 is screwed a member 4 to which is fitted the supply pipe for the solution. An adjusting tap 5 is provided. A similar canula of smaller diameter is used for evacuation of the blood from the right ventricle, the end of the conical ferrule being preferably chamfered to permit of perforating the wall of the heart when introducing the nozzle. This canula may have an indicating glass to enable the passage of liquid to be controlled and has no adjusting tap. When the penetration of the solution has ceased, the opening made in the thoracic region of the animal for insertion of the canulas is closed with a clamp to prevent soiling the flesh during skinning and cleaning. The ingredients in the preservative solution used include sea salt, saltpetre and sugar, and aromatic substances may also be added. By adjustment of the stream of solution it can be arranged to saturate uniformly the front and hind portions of the animal, or the hind portion only, or the front portion more than the hind portion or alternatively. The duration of the process is 2-3 minutes. Specification 322,254, [Class 49, Food &c.], is referred to.

Title: Improvements relating to preventing freezing of the induction systems of internal combustion engines
IPC: C10L1/182
Filed: 1933-08-03
Abstract: 423,510. Actuating - materials. SWAN, A., and HELMORE, W., Royal Aircraft Establishment, Farnborough, Hampshire. Aug. 3, 1933, No. 21777. [Class 7 (ii)] [See also Group XXIX] Prevention of the formation of ice in the induction system is effected by causing an anti-freezing substance to be dispersed automatically therein when, and as, required. The composition of the substance and its method of introduction are as described in Specification 414,410 and the automatic control may be effected by a combination of a thermostatic device and a hygrometer through the action of a servomotor, or by direct mechanical means as shown. Two pipes, having adjacent orifices in the induction pipe, lead to sockets 20, 21, and thus to opposite sides of a diaphragm 24, one side being adjustably vented by a valve 29. The pipe, connected to the socket 21, ends in the induction pipe in a freeze detector comprising an inclined end covered with gauze, or a perforated plate, or a side perforation of a pipe which can be adjusted by rotation. When this freezes over, difference of pressure on the diaphragm 24 causes the induction pipe suction, acting through the pipe connected to the socket 20, to open a valve 22 ; this influences bellows 25, the interior of which is vented by an adjustable valve 28, to allow anti-freezing substance, contained in the casing, to flow past a valve 27. Perforations 31, in the stem of the valve, cause the supply to be reduced when the suction in the induction pipe increases during slow running.

Title: Improvements in toothed gearing and in the method of and means for producing same
IPC: B23F5/20
Filed: 1926-09-04
Abstract: 274,667. Brown & Sons (Huddersfield), Ltd., D., Brown, F. E., and Merritt, H. E. Sept. 4, 1926. Gear cutting. - In toothed gearing of the spur, spiral, bevel or hyperboloidal type, the working surface is composed in part of a surface corresponding to that of a generating cutter of plane or other form, whilst the remainder of the tooth profile is produced by generation from such surface. Thus in Fig. 1, which shows the application to spur gearing, a tooth of a wheel a is formed from a cutter b which rolls in unison with the blank about the centre of a circle c corresponding to the pitch circle of the mating gear. The generating motions are arrested when the cutter reaches the position shown so that the part d outside the pitch line of the gear tooth is of generated profile while the part d<1> is produced by a forming action and corresponds to the cutter profile. In cutting the mating gear, Fig. 2, a counterpart cutter b<1> is employed, this being moved in unison with the blank about the centre of the circle c<1> corresponding to the pitch circle of the gear a and the generating movement being arrested at such a point that only the portion e of the mating gear outside the pitch line is generated. The completed teeth will operate as shown in Fig. 3. The generating surface may be of other than plane form and the generating action need not necessarily be arrested when the surface passes through the pitch point. The cutter may be of the reciprocating type or, alternatively, a rotary cutter or grinding-wheel may be employed. The machine for carrying out the invention may comprise a work-spindle and a cutter-cradle to which the required generating movements may be imparted, the axis of the cradle and work-spindle being relatively adjustable. Means may be provided for arresting the generating motion at a predetermined point, separating the cutter and work, indexing the work, and returning work and cutter cradle to the starting position.
