Loud-speakers.-A loud - speaker comprises a horn communicating with a casing containing a telephone receiver arranged to vibrate a column of air of small cross-section. In order to allow a small diaphragm to be used with a large input of energy, the outlet in the receiver cap is so small that the diaphragm is heavily air-damped. Means may be provided for varying the size of the outlet. As shown, the receiver b is arranged to be a piston fit in the casing a. The cap b<1> has a central perforation d the area of which is about 1-250 that of the diaphragm. A number of perforations f may be provided in addition. These are sealed by a washer c when the receiver is moved to the left. Movement of the telephone receiver within the casing to alter the volume and tone of the sounds emitted may be effected by means of a screw or raok-and-pinion mechanism operated simultaneously with any adjustable feature of the receiver itself. In order to vary the damping independently of the volume of the space c<1>, the washer may have a number of apertures which can be more or less closed by a ring-like shield or an iris diaphragm. According to the Provisional Specification, the aperture in the receiver cap may be the same size as the end of the horn, both having a diameter about 1-6 that of the diaphragm.

Title: Vibration resistant aircraft structures
Inventor: WILLIAMS DAVID
IPC: F01D5/26
Filed: 1960-01-21
Abstract: 942,386. Aircraft framework. MINISTER OF AVIATION. Jan. 19, 1961 [Jan. 21, 1960], No. 2230/60. Heading B7W. [Also in Division F2] In means for preventing bending and torsional vibrations in beam and shaft members a structurally stiff damping element effectively integral with the root anchorage of the vibratable member is pressed in contact with the vibratable member only in a local friction zone remote from the anchorage being otherwise spaced from the vibratable member, the contact pressure being such that dry slipping friction occurs between the damping element and the friction zone of the vibratable member. The clamping element may have a flange on friction pad at its free end. As shown in Fig. 1 when a cantilever A, B, anchored at a base N-N, vibrates over an amplitude H, H small axial displacements in opposite directions occur at lugs C, C which frictionally engage end pads E, E<SP>1</SP> of damping struts D, D secured to the base N-N. The damping action increases as the length I of the struts is made larger and increasing the distance 2b between the contact surfaces C<SP>1</SP>, C<SP>1</SP> of the lugs C, C reduces the stiffness required for the struts D, D<SP>1</SP> for the same amount of damping action. Figs. 2, 3, 4 (not shown) illustrate graphs for selecting the optimum dimensions for the length and the stiffness of the struts and the height of the lugs C, C<SP>1</SP>. In order to resist nodding of the forward part of an aircraft fuselage, Figs. 5a, 5b, 5c, a rigid anchor 53 at the centre of lift X-X of the aircraft has anchored thereto, within an upper 60 degrees sector, twelve high strength, aluminium alloy or beryllium clamping rods 55 which pass through rubber plugs 56 in traverse frame members 51. The flattened ends 57 of the rods 55 are urged into with friction pads 58 secured, with intervening plates 59, to the aircraft skin 50 by means of an assembly which comprises bolts 61, rubber blocks 62, washers 63 and lock nuts 64 and which permits relative motion between the rods 55 and their friction plates 58. A similar arrangement of rods is fitted to a lower 60 degrees sector of the aircraft. The degree of friction required is obtained by adjustment of the lock nuts 64. The nut and bolt arrangement may be replaced by a fluid or electrical system a signal being obtained from the relative movement of the rod and friction plates which operates a servo-response system to bring about an increase in pressure by electrical or fluid means when the movement is greater than a certain predetermined amount. Alternatively an accelerometer which responds to the accelerations due to the aircraft nose vibrations can be used as a source of signal.

Title: Improved friction grip rope puller
IPC: F24D3/08
Filed: 1964-01-20
Abstract: 1,036,171. Rope grips. H. O. DOHMEIER. Jan. 20, 1964 [Jan. 31, 1963], No. 2424/64. Heading F2X. Rope hauling apparatus comprising two frictional rope grips 14, 15 connected by links 16, 17 respectively to a rocking plate 24 on a shaft 25, has a substantially dust-proof casing 12, with an anchorage point 13, from which project an operating lever 18 connected by a link 22 to the rocking plate 24, and a knob 33 for selecting the direction of rope haulage. Slot engagement of the lever 18 on its pivot pin 19, in a disc 20, allows alternative lever ratios. The grips 14, 15 are reciprocated simultaneously in opposite senses so that. when one is gripping the rope and hauling it in one direction, the other is sliding over the rope on its return stroke. For haulage of the rope to the left, the links 16, 17 engage pins 30, 28 respectively on the grips 14, 15. To change the haulage direction, the knob 33 is raised to lift the links 16, 17 into engagement with pins 31, 29 or the grips 14, 15. The knob 33 can be turned to lock it in the raised position. In an alternative form (Figs. 2, 3, not shown) the link 16 is pivoted to a crank 43 rigid with a shaft 25 while the link 17, in the form of a belt-crank pivoted about a pin 57 on a link 56, is connected by a pin 55 to the grip 15 and by a link 52 to a crank 50 supported by shear pins 51 on a sleeve 48 rotatable about the shaft 25. Outside the casing 12, an operating lever 39 pivoted about a sleeve 41 keyed to the shaft 25 may be selectively connected to the sleeves 41 or 48 by a pawl 58 pivoted on the lever 39 and engageable with slots 59 or 60 in the sleeves 41 and 48 respectively. Thus the lever 39 may move either the grip 14 or the grip 15, the two grips being arranged to haul the rope in opposite directions. A spring 61, anchored at 62, acts on the pin 55 to urge the grips 15 and 14 (through links 17, 56) to engage the rope so that as the actuated grip is on its return stroke, the rope is held by the non-actuated grip. To release both grips a link 64, normally locked out of action, is moved left (Fig. 2) to act on the pin 55, through a link 65 to neutralize the action of the spring 61. An emergency operating lever, formed by the member 67 which normally is a carrying handle for the apparatus, has a forked end 71 engageable on an extension 66 of the part 54 of the grip 15 in which the pin 55 is pivoted. A lever 18 of the type shown in Fig. 1 may be provided to operate the grip 14.

IPC: F04B49/20
Filed: 1956-01-26
Abstract: 784,202. Governors; rotary engines &c. JAEGER MACHINE CO. Jan. 26, 1956, No. 2575/56. Classes 57 and 110 (2). [Also in Groups XXVIII and XXIX] In an I.C. engine having a valve 16 for controlling the speed thereof and driving a compressor, said valve is controlled by a governor 17 to which it is connected by a lever 18 and a linkage 19. The governor balls 20 mounted in a slotted guide disc 21 driven by the governor shaft from the engine move outwardly under centrifugal force to co-operate with a cam collar 22 to swing the lever 18, movement of which is resisted by a tension spring 25 anchored to the end of a lever 26 on a regulator 40 actuated by the discharge pressure of the compressor. In one embodiment the governor is loaded by two tension springs, one of which is similar to the spring 25. The lever 26 is loaded by springs 30 and is movable by a plunger 43 bearing against a diaphragm 42 in the regulator housing 41. A line 46 conveys compressor discharge air to a branch 47 and one side of the diaphragm 42, and to a manually adjustable regulating valve 50 from which air up to a predetermined maximum pressure is led via a line 51 to the other side of the diaphragm. Until compressor discharge pressure exceeds this maximum both sides of the diaphragm are subjected to equal pressure and the springs 30 hold lever 26 in the position where the governor spring 25 is set at full speed position. When the discharge pressure exceeds said maximum, a differential pressure exists in the housing 41 and diaphragm 42 moves the lever 26 to decrease the tension in the spring 25 to move valve 16 towards low-speed position. Lever 26 is movable manually by means of a lever 37. Fig. 7 shows a governor 17b controlling a valve 16b controlling the speed of an I.C. engine 11b driving a rotary type compressor 10b delivering compressed air into a receiver 12b having an oil separator tank 120b having a safety valve 150b connected via a pilot valve 15b to the compressor unloading mechanism 13b and via a lead 46b to the pressure-regulating valve 50b and to the regulator controlling the tension in the governor spring 25b.
