Abstract: 211,129. Struxiano, L. A. L. Feb. 10, 1923, [Convention date]. Earpieces and attachments; magnetic instruments.-A telephone receiver of light construction, which may be partly introduced into the ear of the user, is provided with a permanent magnet 2 preferably of horse shoe form, which is supported at the, rear end of the casing 1 and directed towards the front so that the centre of gravity of the receiver is brought to the point of contact of the nipple 5 with the ear conduit or forwardly of this point. The ends of the magnet 2 may be inserted through the side of the casing 1, and pole pieces 7 secured thereto and to the casing 1 by screws 16. Each pole piece 7 is surrounded by a coil 3, and between the cheeks 8 of the coils and the bottom of the box are metal thimbles 9, 10 insulated by insulating material 11 to which the terminals of the coil and the external terminals are led. The casing 1 may be reinforced by an inner tubular lining 24. In a modification the case has no end wall but is closed by a screw plug screwed into the bottom of the casing. The nipple 5 is carried by a cover 17 screwing on the casing 1, and this cover 17 carries the diaphragm 4 to which a soft iron armature 19 is attached. The diaphragm 4, when of rigid material such as ivory, metal or fibre, may be clamped between a flange on the cover 17 and a ring 20. But if it is of flexible material, such as animal, vegetable or textile substances, it is stretched between two rings 22, 21, Fig. 5, the outer edge of the ring 21 being turned over to hold the ring 22 in plase. The device thus formed may then be clamped by the ring 20, or the ring 21 may be screw-threaded and screwed into the cap 17. A slide 26 is mounted on one or both branches of the magnet 2, and a lever 29 is mounted on a spindle 28 carried by the slide, or flat portion 30 with serrated face being pressed by a spring 31 against the tragus of the ear. In a modification, Fig. 6, the cap 17 is bent as shown, and the straight magnet 2 rests against the back of the case 1, being secured thereto by a screw 35 and a washer 34. The connecting lead 14 may be led over the ear so that a pull on it tends to force the receiver into the ear.

Title: Wear adjuster for magnetic friction devices
IPC: F16D27/112
Filed: 1960-01-28
Abstract: 887,056. Friction clutches. WARNER ELECTRIC BRAKE & CLUTCH CO. Jan. 28, 1960 [Feb. 20, 1959], No. 3171/60. Class 80 (2). An electromagnetically engaged friction clutch has spring means separating the friction surfaces when the clutch is disengaged which give a constant separation irrespective of wear of the plates. An armature 25 is bolted to a sleeve 30 splined to a sleeve 32 adjustably secured to a driving-shaft 10 and is engageable with friction surfaces 23 carried by polepieces 15, 16 fast with the driven shaft 11, the polepieces cooperating with a stationary coil 12. The armature 25 is disengaged by a ring 40 of channel section providing axial outer, 43, and inner flanges and a radial base 44. The inner flange is interrupted and slotted to form lugs 50 resiliently gripping the sleeve 32. Fingers 42 are stamped out of the base 44 and the free ends 47 engage the bottom 52 of a recess formed in a flange 29 of the armature-supporting sleeve 30. When the coil is energized to engage the clutch the ends 47 of the fingers are forced back into line with the lugs 50 and then the ring slips over the sleeve 32. When the coil is deenergized the fingers 42 shift the armature 25 axially until the heads 53 of the bolts securing the armature to the sleeve 30 engage the base 44 of the ring and the desired separation is obtained. A snap-ring 35 received in a groove in the sleeve 32 limits the axial movement of the sleeve 30. Specification 725,587 is referred to.
Patent GB-344162-A (GB)
Title: Vertical internal combustion engine with direct-driven air compressor
IPC: F02B71/04
Filed: 1930-01-30
Abstract: 344,162. Direct-driven air compressors. BINARD, J. P., 29, Rue Mogador, Gravelines, Nord, France. Jan. 30, 1930, No. 3258. Convention date, Feb. 1, 1929. [Class 8 (i).] An air compressor 3 is directly driven by an internal-combustion engine 1. On the downstroke of the piston 4, the arm 12 engaging the rack 19 opens the relief valve 14, enabling air below the I.C. piston to escape. When the lug 21 engages the finger 15, valve 14 is closed and the enclosed air compressed, fuel being supplied by the injector 10 when the lug 20 engages the device 5. Explosion taking place by spontaneous combustion, the piston rises till the exhaust port 43 is uncovered. Air compressed in the cylinder 3, first escapes through valve 28 for scavenging the cylinder 1 ; after this valve e is covered the compressed air passes to the storage tank through the pipe 34. To enable the piston to be cushioned when the storage tank pressure is low valve 35 has an inclined row of holes 36. Thus when the air pressure in cylinder 3 rises, the valve is forced upwards and most of the holes 36 will be covered, air only escaping slowly to the pipe 34. When the storage pressure rises, this, acting on the inside surface of the valve will assist the spring 38. Control may be effected by throttling the initial air supply to the cylinder 3 by throttle 31, thus retarding the speed of fall of the piston. To start the engine compressed air is supplied to the valve 42. Should the piston make an overstroke, the lug 20 engaging the cam 50 will release the finger 25, and this, meeting lug 20 will prevent the return stroke.

Title: Improvements in or relating to Apparatus for Regulating the Speed and Power of Internal Combustion Engines.
Inventor: RICARDO HARRY RALPH
IPC: F02D15/00
Filed: 1918-02-27
Abstract: 123,585. Ricardo, H. R. Feb. 27, 1918. Regulating.-The inlet valves of an engine for aircraft &c. are each actuated by an adjustable cam controlled by' a barometric device which acts upon a valve for regulating the supply and delivery of a liquid to and from a chamber containing a piston connected to mechanism for adjusting the cam. Located between a pair of cams A for actuating the exhaust valves is an inlet valve cam C, C', the portion C<1> of which may be adjusted angularly by a pin C<2> carried on the shaft D. Rollers D<2> are secured to the end of the'shaft and work in helical grooves E' formed in a sliding sleeve carried by a piston F which reciprocates in a cylinder G<1> to which is supplied oil under pressure from a lubricating system. The cylinder G<1> communicates through ports G<2>, G<3> with a chamber K in which slides an open-ended valve L connected by a lever Q to a rod M secured to the movable member 0 of a barometric device O<1>. The lever Q is hinged at F<2> to the piston, and at its upper end it is adjustably connected to the rod M. A movement of the rod M in a left-hand direction places an oil supply port K<1> in communication with the port G<3> leading to the cylinder G', admission of oil to which displaces the piston and so adjusts the cam as to reduce the period of opening of the inlet valve. This displacement of the piston alters the position of the fulcrum of the lever Q<2>, thus moving the valve and closing the port G<3>. A movement of the rod M in an opposite direction opens the port G<3> through which the oil from the cylinder is discharged into the interior of the valve. A manual actuation of the valve may be effected by a hand-lever R which can adjust the cam to prolong but not reduce the opening of the inlet valve. The cam may be adjusted axially as described in Specification 127,613.

Title: Improvements in and relating to aircraft gun installations
IPC: F41G9/00
Filed: 1948-02-07
Abstract: 720,080. Sighting aircraft guns. BOULTON PAUL AIRCRAFT, Ltd., and NORTH, J. D. Feb. 7, 1949 [Feb. 7, 1948], No. 3608/48. Class 92(2). An aircraft gun installation comprises a gun or guns mounted in the aircraft, a movable gun sight, means for measuring the angular displacement and/or time derivatives of the angular displacement of the gun sight, means for measuring angular displacement of the aircraft, and servo mechanism for moving a control surface of the aircraft in accordance with a desired function of the angle of sight and the angular displacement of the aircraft. In the drawing a sighting and range computing unit 1 provides a signal fn(°), a function of the angular displacement of the sight, which is fed to a servo mechanism 2 actuating a control surface 3. A gyro unit 6 provides a signal fn(°), a function of the aircraft displacement, which is also fed to the servo mechanism 2. Means e.g. a warning light, may be provided to indicate when the guns may be fired within a permissible angular error should it be unnecessary to have the gun accurately aligned on the target. The permissible error varies with range and a computer 7 feeds the warning light mechanism with a function of the range of the target. This range function may also be fed through a computer 8 to the servo mechanism 2 in order to vary the sensitivity of the control with range. The angle of sight and the angular displacement of the aircraft can be obtained by potentiometers, and the latter displacement may also be obtained by means of a strain gauge measuring the precessional torque of the gyro unit 6. Specification 720,079 is referred to.

Abstract: 340,161. Akt.-Ges. C. P. Goerz Optische Anstalt. Feb. 11, 1929, [Convention date]. Order-type apparatus.-In a device for transmitting electrically to a distance angular values which are subdivided into groups of units, tens, hundreds, &c., each group having contacts adapted to be engaged by sliding contact springs secured to a pointer, the angular intervals between two successive " units " contacts, instead of being of a value substantially <1>/10 of the interval between successive "tens" contacts, is equal to said value increased by the angle between two successive " units " contact springs or a multiple of this angle. The invention which is indicated in Fig. 2 , is described by comparison with a known device shown in Fig. 1. In the construction shown in Fig. 1, twenty " units " contacts e0 to e19 are fixed to a disc S of insulating material at intervals apart of 1‹, and are connected together in pairs, as shown. Eighteen contact springs a1 to a18 connected together are adapted to slide over the " units " contacts. Thirty-six " tens " contacts z0 to z35 are arranged for engagement by a sliding contact spring b, and four " hundreds " contacts h0 to h3 for engagement by a spring c. A contact ring R is engaged by a spring d. The contact springs are connected to a pointer, the position of which is indicated by means of groups of lamps, the group G0 to G9 being connected to the "units" contacts, the group G0<1>, G10 to G90 to the " tens " contacts, and the group GO", G100 to G300 to the " hundreds ' contacts. To avoid the units contacts being so closely associated, they are spaced apart as shown in Fig. 2 an angular distance equal to the distance between two successive springs a1, a2, viz., 20‹ to the "units" angle of 1‹, i.e. a total distance of 21‹. As the range of all the "units" contacts 21‹ apart would exceed 360‹, the units are arranged in two groups e0 to e9 and e10 to e19, the second group being displaced 10‹ with respect to the first group. In modifications ten "units" contacts and thirty-six " units " contact springs are employed.
