Title: Improvements in Internal Combustion Motors for Torpedoes.
Inventor: ROYER HENRI
IPC: F02M67/02
Filed: 1918-03-13
Abstract: 130,682. Royer, H. Jan. 17, 1917, [Convention date]. Torpedoes, locomotive.-Relates to torpedo engines of the kind described in Specification 22439/12, [Class 7 (ii), Internal-combustion engines, Carburetting-apparatus &c. for], in which the liquid fuel flows into the cylinder continuously, and consists in causing the supply of fuel to the cylinder to be increased gradually after the engine has been started by compressed air. Two ways are described of supplying the fuel from a reservoir R by air pressure from a pipe T. In the arrangement shown in Fig. 1, the cock r is opened when the torpedo is launched, but oil does not flow to the cylinders through the pipes t until its level reaches the point N<1>, and the maximum rate of flow is not attained until the level N<2> in the air vessel C is reached. In that shown in Fig. 2, there is no air vessel, and the reservoir R is only partly full, the air valve a being opened slowly and the rise of air pressure in the reservoir R retarded by restricting the outlet d of the pipe T. The slow opening of the valve a is performed by a device not described which also assures the initial immobility of the horizontal rudder.

Title: Improvements in suction conveyers
IPC: B65G53/24
Filed: 1919-02-24
Abstract: 137,159. Jackman & Co., J. W., and Leigh, A. P. Feb. 24, 1919. Pneumatic conveyers and elevators.-A suction conveyer for sand, grain, &c., has a single conveyer pipe through which the material is conveyed in either direction. The application of the invention is described to a plant for conveying sand in a foundry to or from the sand preparing or mixing plant. The spent sand is drawn through pipes d' into the pipe d which delivers into a hopper D. , A pipe d' connects the hopper to the sand - preparing plant A, from which the sand is delivered in a pile B. The pump or fan exhauster C is connected to a dustextractor F, from which a pipe E leads to the hopper D, and a pipe G extends to the parts of the foundry at which sand is to be delivered. At these parts, the pipe G is connected to hoppers H, which can be connected by flexible pipes h<1> to the pipe d when desired. These pipes are used alternatively to connect the sections of the pipe d when the spent sand is being collected. A branch pipe d<2> depends from the pipe d to the pile B. When sand is being distributed, the pipe G is connected to the pump C and to one of the hoppers H, and the same.hopper is connected by its pipe h<1> to the pipe d. Sand passes through the pipes d<2>, d, h<1> to the hopper.

Abstract: 567,712. Closing food containers hermetically. CONTINENTAL CAN CO., Inc. March 19, 1943, No. 4530. Convention date, May 13, 1942. [Class 125 (ii)] [Also in Group VI] In a machine for closing food containers hermetically, the cover 36, Fig. 4, is supported just above the mouth of the filled container 7 while steam is projected laterally from channels 51, 65 so that the jets meet and are deflected downwards into the container. The closing is then effected by immediately moving the container 7 upwards and securing the cover on the container. In one embodiment, the filled, open containers are moved along a steam tunnel 12, Fig. 1, by teeth 11 on a conveyer 10, steam being admitted through pipes 27, 18, Fig. 7, and apertures 24. The containers are engaged by recesses 29 in a rotating turret 30, covers being led from a position 34 to the position shown in Fig. 4, where sealing takes place. The steam tunnel may be omitted. Specification 342,457, [Group XXII], is referred to.

[Class 18] [See also Group XVIII] In display apparatus for packets and flat articles, of the kind comprising a carrier adapted to hold a pack of articles, spring means for advancing the articles to a display position, and stop means for retaining the foremost packet in such position, until its removal, when the next article is advanced, the carrier is a U -shaped sheet metal frame, one side of which has, at or adjacent its free edge, a pair of projections 31 forming the stop means, and spaced to provide between them, a display opening. The foremost article is retained against the stops 31 by a spring pressed plate 27. To replenish a frame, it can be slid out along horizontal grooves in the enclosing recess 13, as in Fig. 2, a fresh pack inserted through the open end 33, and the frame then slid back, a lip 22 on an integral tongue 21 engaging in a slot 23 to secure it in position. The finger opening 35 in the top of the frame allows the number of articles therein, to be counted. Several such frames may be arranged in an ordinary rack, or in four opposite sides of an octagonal stand 10 supported on an octagonal plinth 11 which can be rotated on a heavy base 38 by means of a pivot 39, and metal spider 40 carrying balls 41. Fillets 37, extending part of the way down pillars 12 allow frames of greater width to be used at the bottom of the stand. A disc 44 serves as a thumb piece to rotate the stand, and may bear the price of the packets.

Abstract: 1,081,661. Time switches; thermal switches. ETABLISSEMENTS CARPANO & PONS SOC. ANON. Feb. 2, 1966 [Feb. 2, 1965], No. 4627/66. Heading H2B. A Timing device comprising a synchronous motor (4) driving a cam 2 whose angular position on its shaft 3 is adjustable, the cam actuating through a lever system an electric switch, includes two levers 11, 14 pivoted on a common shaft 10 and connected through a hairpin spring 13, the cam 2 acting on lever 11 and the lever 14 actuating a switch blade (17) (Fig. 2, not shown). A C-spring (16) provides for snap-action movement of the blade (17). Surface 9 of cam 2 depresses nose 12 of lever 11, which in turn rocks lever 14 via spring 13. When a blocking lever 21 is moved from position 25 to position 25<SP>1</SP>, however, so that a segment 23 of lever 21 engages the tail 20 of lever 14, the lever 14 is blocked and the movement of lever 11 is absorbed by spring 13. A tipping projection 26 restores lever 21 to position 25 if blocking is not required for more than one cycle. With lever 21 in position 25<SP>11</SP>, however, lever 14 is blocked until lever 21 is moved manually back to position 25 or 25<SP>1</SP>. An intermediate lever (31) (Fig. 8, not shown) may be inserted between cam 2 and the first lever (11<SP>1</SP>), the shaft (33) of lever (31) being rotatable for adjustment purposes. When applied to defrosting a refrigerator, the timing device initiates defrosting via a boss (42) on cam 2 engaging lever 11 and actuating the switch via lever 14, an extra lever (38) then latching a nose (41) on lever 11. At a certain temperature a thermally responsive capsule (47) expands to unlatch the nose (41) of lever 11 from lever (38) and a leaf spring 30 pivots levers 11, 14, back to their original positions (Fig. 9, not shown). A second boss (43) on cam 2 unlatches lever 11 if the capsule (47) is ineffective after a certain time.

An axial-flow air compressor forming part of a gas turbine plant comprises inner and outer walls which are spaced apart to form an annular air intake passage, the inner wall terminating in a hollow nose cone, hollow fixed guide vanes which extend across the intake passage to connect the inner and outer walls, a ring of hollow adjustable pitch stator blades with control means connected to their outer ends, means for supplying a flow of heated gas through the outer ends of the guide vanes to their inner ends, and ducting for conveying the flow of gas along the inner surface of the nose cone to the interior of the stator blades through their inner ends. The air intake casing comprises a casing 10 surrounding a front bearing housing 11 terminating in a hollow nose cone 13. Twelve fixed radiallydisposed hollow guide vanes 14 support the housing 11 from the casing 10 and a ring of adjustable stator blades 15 connected by rocker arms 35 to pitch adjusting means are arranged between the guide vanes 14 of the first-stage rotor blades 16. When de-icing of the compressor intake is required, hot compressed air tapped from the compressor is conveyed to the inlet 18 and manifold 17. This air passes through the passages in the guide vanes 14 to a number of annularly-spaced chambers 19 connected by openings 20 to an annular passage 21 formed between the cone 13 and the annular part 22 of a hollow drum structure 23 supported by the guides vane 14 in the housing 11.
