Title: Improvements in and relating to apparatus for the determination of wave energy direction
IPC: G01S1/72
Filed: 1920-07-08
Abstract: 147,669. Steward Davit & Equipment Corporation, (Assignees of Mason, M.). June 25, 1919, [Convention date]. Locating subaqueous sounds. -A number of spaced receivers with branching connexions are arranged so that their effects are added in phase as regards sounds arriving from a given direction, while sounds from any other direction give interfering components and a weaker resultant. The receivers consist of non-resonant diaphragms or rubber nipples, Fig. 11, which transfer the sound direct from the water to air-tubes, which are connected together in pairs and pairs of pairs &c., as shown in Figs. 1 and 2, and deliver the sound to the ear-pieces of a stethoscope. The lengths of the branch connexions are computed so as to compensate for the different times at which the sound reaches the different receivers. For example, in the arrangement shown in Fig. 1, the two branches of each pair are of equal length, so that the sound produces a maximum effect in the stethoscope when it arrives at right angles to the line of receivers 1 - - 8 (this is referred to as " beam compensation "), while in Fig. 2 the two branches of each pair are of unequal length, and of such a ratio that the response is a maximum for sounds travelling in the direction of the arrow, parallel to the two lines of receivers (" forward compensation.") Fig. 4 shows an arrangement of four lines of receivers in which beam and forward compensations are combined. In all these arrangements the receivers are shown as divided into two groups connected to separate ear-pieces, so that the binaural sense is brought into play. To find the direction of a sound, the system of receivers is rotated until the sound is heard with maximum intensity and binaurally centred; any movement from this position both weakens the sound and makes it appear to move to one side or other of the listener's head. The binaural effect may be dispensed with, the sounds from all the receivers being united in a single tube. To avoid reflection, the cross-section of each tube should be equal to the sum of the cross-sections of its two tributary branches, and if the cross-section of a tube is to be reduced it should be done by gradual tapering. Two lines of receivers, connected as shown in Fig. 2, may be mounted rotatably in a support which passes through the ship's bottom, and which can be lowered until the receivers are below the level of the keel. Each line of receivers, with its connecting-tubes, as shown in part in Fig. 10, is enclosed in a perforated water-filled sheet-metal casing.

Filed: 1929-06-27
Abstract: 330,787. Juhlin, G. A., and Associated Electrical Industries, Ltd. June 27, 1929. Running generators in series. -In a system employing generators in series for supplying motors as in marine propulsion where the generators are provided with main and series field windings, when it is desired to disconnect a generator the machine is short circuited, and to prevent sparking at the disconnecting switch the main field is reversed so as to oppose the series field. In Fig. 2, when the shortcircuiting switch 6 has been closed, switch 12 disconnects the main field 3 of the generator 1 from the exciter 9 and connects field 3 across the generator so that the main field 3 opposes the series field 2. At the same time switch 13 disconnects the exciter field 10 from the source of supply 11. Switches 12 and 13 may be coupled together and operated by the same handle. Where the exciter is permanently connected to the main field winding a modified arrangement provides for the exciter field being disconnected from its supply circuit and connected across the generator so that the exciter field and therefore the main field is reversed. In another arrangement the exciter is provided with a second independent field winding which is connected across the generator armature when the exciter field winding proper is disconnected and which reverses the exciter field.

Abstract: 1356281 Helicopter rigid rotor hubs; propellers SOC DE CONSTRUCTION ET D'EXPLOITATION DE MATERIELS ET MOTEURS 10 June 1971 [11 June 1970] 19873/71 Headings B7W and B7V  A rigid rotor comprising a flat hub member 2 connected to blades 4 by arms 3 which exhibit high bending resistance and low torsion resistance (as disclosed in Specification 1,245,168) is equipped with means 120 which opposes any deformation of the hub 2 produced by simultaneous flapping of all the blades 4 in a direction parallel to the shaft 1. Means 120 comprises pairs of metal cables 121 arranged in the form of a polygon which is parallel to the flat hub 2. The outer ends of each pair are connected by rings 122 to shackles 123 pivotable on extensions of the arm mountings 25 (see Specification 1,245,168). The inner ends are joined by tightening means 124, each (124a in Fig. 3) comprising an externally threaded sleeve 125 secured to the end of one cable, an abutment 127 secured to the end of the second cable, an internally threaded nut 126 through which the second cable can extend, and a compression washer 128. Nut 126 is screwable on sleeve 125 to adjust the tension in the cables 121 and to oppose any simultaneous downward (in Fig. 1) flapping, while washer 128 prevents loosening of the ties during flapping in the opposite direction (upwards in Fig. 1). Means 120 may be placed above, below or on both sides of hub 2; the arrangement does not oppose simultaneous flapping of the individual blades in different directions when tilting of the tip path plane is required. Although described in terms of a rotor for a helicopter, the invention may be applied to rotors for variable-pitch propellers, lifting rotors, aeroplane propulsion screws and axial gas turbines.

Abstract: 1,007,457. Ground-compacting machines. B. K. R. BEIERLEIN. May 24, 1962 [May 25, 1961; Feb. 14, 1962], No. 20023/62. Heading E1G. [Also in Division F2] The base plate of a ground-compacting machine, which includes at least one vibrator to act on the base plate to compact the ground and propel the machine, is downwardly convexly curved and/or angled longitudinally of the machine so that the area of contact between the baseplate and the ground decreases as the density of the ground increases. As shown, Fig. 1, a base plate 10 with a replaceable reinforcement 100 supports vibrators 4, 40 selectively connectible through a clutch (not shown) and output shafts 30 to a motor 3 resiliently mounted on the base plate. To cause the machine to travel to the left of Fig. 1 the leading vibrator 40 is coupled to the motor; for travel to the right the vibrator 4 is coupled to the motor 3, the direction of rotation of the vibrators being the same for both directions of travel. As the ground becomes compacted the area of contact between the base plate and the ground is reduced to that shown in Fig. 4, the specific pressure being thereby increased. An alternative form of base plate shown in Fig. 5 may be varied by omission of the central section 102. Figure 8 shows a machine with a single vibrator the direction of travel being dictated by tilting the machine, to the right as shown for travel to the right and vice versa, the direction of rotation of the vibrator being immaterial. A steering rod such as the rod 20 of Fig. 1 may be provided to maintain the tilted position with a less steeply curved base plate. Forward and backward movement can be achieved with a single vibrator without tilting the machine by pivotally mounting the vibrator for movement between the front and rear ends of the machine. A machine (not shown) including at least three vibrators can be steered by selectively coupling the respective vibrators to the motor.

IPC: C10L5/22
Filed: 1927-07-29
Abstract: 305,051. Morgan, J. S. July 29, 1927. Centrifugal machines ; processes; moulding fuel; feeding.-Aggregates or agglomerates of carbonaceous material are formed by causing rapid relative movement between powdered material and a solid surface in presence of a binding agent, and, if necessary, breaking up the aggregate if unduly large. The binding agent may be derived from the carbonaceous material e.g., by heating, or may consist of liquid or vaporized oil &c. According to one example, coke and the vapour of a high boiling oil are introduced into a rapidly-revolving cylinder whereon the material builds up by centrifugal force. The material is removed continuously or intermittingly and broken up. In a modification, finely-divided coal or semi-coke is fed downwardly through a vertical tube surrounding a rotating worm and falls on to an upwardlydished plate carried by the worm spindle. The material is projected from the plate on to the inner surface of a cylinder which is not rotated but is gradually raised and lowered to build up the material. The coal &c. is heated to a temperature of 300‹ C. Liquid or vaporized oil may be added, either mixed with the coal or sprayed into the apparatus. In a further modification, coke is transported at high velocity in a current of oil vapour and consolidated against a cooled plate or cylinder; alternatively, the material is injected by a blast of gas into a mould to form briquettes. Binders which polymerize or condense are preferably employed, e.g., a solution: of pitch. A phenolic body may be added to the mixture and sprayed in an atmosphere of formaldehyde.

Abstract: 516,082. Gill frames; packing slivers into cans; cleaning. GREEVES, Ltd., J. & T. M. EVES, R. V., and EVES, H. T. July 8, 1938, No. 20225. [Classes 120 (i) and 120 (iii)] The sliver delivered from a gill frame for drawing flax &c. into a can is packed therein by a reciprocating packer counterbalanced by a weight raised and lowered by a rotary crank or eccentric and rigid connecting rod so that the effective weight may be increased to raise the packer and decreased to allow the packer to fall by gravity ; when the frame is of the push-bar type the main drive is to the main drawing roller which is geared to. the crank or eccentric, the feed rollers and other parts of the frame. As shown the main drawing roller A is driven from a motor C or from overhead shafting and is geared to a shaft N carrying the crank or eccentric H connected by the rigid rod h' with the counterweight W on a quadrant G connected by a chain or band e<2> to a pulley g' on a shaft K also carrying a pulley g connected by a chain or band e<1> to the vertical rod e carrying the packer E. In a modification the rod h<1> is connected to a weight sliding in vertical guides and the chains or bands e<2>, e' are connected to a single pulley on the shaft K, and in a further form the rod is connected to a pivoted lever carrying the weight at one side of the pivot and an adjustable screw at the other side of the pivot, the screw supporting a pivoted lever connected to the rod e by a link which may be slotted to give lost motion so that the packer can adjust itself to the amount of sliver in the can independently of the other packers. The connecting rod h<1> is disposed so that during one half of a revolution of the disc it pushes against the weight and so increases its action in raising the packer and during the other half revolution it pulls the weight and diminishes its action so that the packer is permitted to fall by gravity. The main drawing roller A is driven from a pulley B on its shaft a, a loose pulley B<1> being mounted adjacent the pulley B on an independent stud b coaxial wth the shaft a. The shaft N carrying the crank disc H passes through the standards M<1> to give substantial support to the overhung crank pin h and the projecting end n of the shaft provides the drive for the alarm bell stop motion or a revolution counter. The dust collecting pan P disposed under the gill bars is fixed and has a hinged end p with quadrant side pieces Q to form a trough when the end is opened for the dust to be raked out of the pan.
