Title: Improvements in engine starting apparatus
IPC: F02N99/00
Filed: 1931-10-09
Abstract: 382,405. Turning-gear. ECLIPSE AVIATION CORPORATION, 545, North Arlington Avenue, East Orange, New Jersey, U.S.A. Oct. 9, 1931, No. 28120. Convention date, Oct. 13, 1930. [Classes 7 (iv) and 7 (v).] In an inertia starter in which a flywheel is set in rotation by hand or by an electric motor and its energy is transmitted to a driving member through reduction gearing, a switch on the dashboard of a motor vehicle or the instrument board of an air craft is arranged to control from a single point the energization of the motor, the engagement of the driving member with the engine crank shaft, and the supply of electric current in an auxiliary ignition circuit during starting. The flywheel 11, Fig. 1, may be driven from the electric motor 44 through a clutch (not shown), and is connected through toothed and planetary gearing and a multiple-plate friction clutch 27 to a clutch jaw 25 movable axially into engagement with the clutch jaw 26 of the engine. The toothed gearing comprises a pinion 13 on the flywheel shaft, pinions 14, 16 on a bellshaped member 15, and an internally toothed gear 17 integral with a sun pinion 21. Planet wheels 22 rotatable on the end of a barrel member 20 mesh with the sun pinion 21 and a fixed internal gear 23. The barrel 20 is connected through the clutch plates 27 to a nut 28 engaging a threaded shaft 34 on which the clutch jaw 25 is longitudinally splined. The flywheel 11 can be set in rotation manually by means of a cranking shaft (not shown) driving through a bevel gear 43 on a shaft 19 integral with the barrel member 20. The clutch jaw 25 is moved into engagement with the jaw 26 by an axial rod 40 pivotally connected to the arm 81 of a rock shaft 79, on the upper end of which is mounted a bell crank 74 actuated by the control switch 45, Figs. 2 and 5. This comprises a spring-controlled rod 48 connected by a pin and slot 76 and a rod 75 to the bell crank 74. The rod 48 is provided with a metal disc 59 for engagement with contacts 50, 51 in the circuit 55, 56 of a solenoid switch 52 for the motor 44, so that inward movement of the rod 48 switches on the motor 44 to set the flywheel in rotation, and outward movement of the rod effects the engagement of the jaw clutch 25, 26 in order to start the engine. For effecting the ignition at starting, the bell crank 74 is connected through a spring 109, threaded sleeve 110, and rod 107 to an insulating rod 105 normally bearing against the spring armature 98 of an ignition coil 92, the secondary winding 93 of which is connected to the spark plugs 104. On the outward movement of the control rod 48, the release of the spring armature 98 by the rod 105 allows the ignition coil to come into operation.

Patent GB-493667-A (GB)
Title: Improvements in or relating to amplifying systems for modulated high-frequency oscillations
IPC: H03F1/06
Filed: 1937-10-19
Abstract: 493,667. Valve amplifying circuits; impedance networks. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 19, 1937, No. 28510. Convention date, Oct. 22, 1936. [Classes 40 (iii) and 40 (v)] A system for amplifying modulated highfrequency currents comprises four valves 21, 22, 33, 34, of which the valve 21 is biassed to bottom bend, the second valve 22 is biassed so that it only passes anode current when the carrier amplitude exceeds a datum value less than the mean carrier, whilst the other two valves 33, 34 are biassed equally and to such extent that anode current only passes when the carrier exceeds a datum value greater than the mean carrier. The load impedance L is connected in series with the terminals 5, 6 of an impedance-inverting network 7, the output terminals of an impedance-inverting network 11 fed by the valve 34, and with the output coupling of the valve 21. The other terminals 8, 9 of network 7 are connected in series with a network 10 associated with the valve 33 and with the output coupling of the valve 22. The surge impedance of the networks 10, 11 is half the surge impedance of the network 7, and the latter is half the load impedance L. The carrier is supplied to the grid circuits of the four amplifiers in such phase relation that after the phase changes produced by the networks, the load L is fed in the same phase by all the amplifiers. This is effected by applying the carrier to the grids of valves 22, 33, 34 at phase angles displaced by 90, 180, and 90 respectively with relation to the carrier applied to the grid of the valve 21. The anode circuits 31, 32 of the amplifiers 21, 22 are parallel-tuned and inductively coupled to a coil 41, 42 in series with a condenser 51, 52. The network 7 comprises series condensers 57, 57<1> and a shunt coil 47 all of the same reactance at the carrier frequency. The networks 10, 11 comprise coupled inductances 43, 43<1>, 44, 44<1> all of which are series-tuned to the carrier frequency by condensers 53, 53<1>, 54, 54<1>. The condensers located in the same circuit may be united to form a single unit. Push-pull valve pairs or parallel-connected valve groups may be used in each of the amplifiers. In a modified system, the load impedance L is connected across the terminals 8, 9 of the network 7, and the surge impedance of the network 7 is double that of the load, Fig. 4 (not shown). The Specification also refers to a known system, Figs. 1 and 2 (not shown), employing only two amplifiers one of which feeds the load directly and operates at all values of carrier, whilst the other feeds the load through an impedance-inverting network and operates only when the carrier rises above its mean level. This system improves the energy-conversion efficiency as compared with the usual single amplifier, and efficiency is further increased by the four-amplifier system of the present invention. Specification 471,423 is referred to.

Title: Pneumatic impact tool
IPC: B25C1/00
Filed: 1958-09-08
Abstract: 841,799. Nailing. GOOD. R. F. Sept. 8, 1958, No. 28760/58. Class 89(3) [Also in Group XXIII] A single-stroke, pneumaticnailing-machine comprises a cylinder with a work-engaging- device on the front end, a piston having a normal position, in which it engages a latch, at the rear-end of the cylinder while air-pressure accumulates, and a second position which produces a blow by impact-means carried on the piston and projecting beyond the front-end of the cylinder. As shown, a cylinder 20 has a piston 22 connected to a forwardly-extending piston-rod 23, the end of which engages a latch-mechanism 27 comprising a shaft 92 having a groove 93, and which may be released by a trigger to allow the piston to move past the groove and produce a blow. The nail-holding-device comprises a body-portion 123 slidably mounted in the front of the foot and held in the forwardposition by. a spring 124. A tube 126, from a supply of nails, flairs into a bore 125, the nails being supplied by exhaust-gas from the tool, and held in position by a number of jaws 128 urged inwardly by springs 130. When the nail-holder is pressed against the work, its rearward-parts compress the spring 124, which unlocks the trigger-safety-mechanism, so that on pulling the trigger the shaft 92 rotates and allows the pistonrod to strike the nail. On releasing the nailholder from the work the latch again engages the end of the piston-rod, which has been retracted, and the trigger-locking-mechanism operates to prevent a shot being fired until the nail-holder is again pressed against the work.

Title: Chromatic mouth organ
IPC: G10D7/12
Filed: 1948-11-05
Abstract: 663,650. Mouth organs. BIBUS, H. Nov. 5, 1948. [Nov. 5, 1947] No. 28830/48. Class 88 (ii). In a chromatic mouth-organ reeds are arranged in sets of 3 or more each set lying in a vertical plane and at least two of the set having a common reed cell, the flow of air through which is individually controlled by manually operated means such as push buttons. Fig. 10 shows an arrangement of reeds in which depression of a button having a particular note marked on it allows that note to be played by exhalation and a note a semi-tone lower by inhalation. Three reeds F, F# and G are arranged vertically above one another, the first being operated by inhalation and the other two by exhalation. Depression of the F# button 26<SP>1</SP> causes the rotation of the F# shaft 29<SP>1</SP> (which extends throughout the length of the instrument). The wire 191 thereby causes the spring loaded valve 13 to recede from the mouthpiece to allow the F# reed to be sounded by exhalation and the F reed by inhalation. Likewise depression of a G button (not shown) causes the rotation of the G shaft to cause the valve 14 to recede whereupon exhalation sounds the G reed. Each shaft 29 is arranged to operate the slide valves in all octaves of the note which it represents. The shafts are duplicated at intervals to enable the buttons to be repeated at various points of the keyboard as shewn in Fig. 8 in which the buttons are arranged so that for a given touch (i.e. combination of relative finger positions) the same chord is played whatever key is chosen. In a modification, Figs. 13, 14 (not shown) reeds are arranged in sets of four, adjacent reeds in a vertical line being separated by a semi-tone, two being played by inhalation and two by exhalation. The intervals between adjacent reeds on the same level is three semi-tones so that the length of the instrument for a given range of notes is reduced, but the instrument has the disadvantage that chords having semitone intervals cannot be played. Figs. 15, 16 (not shown) indicate a four-reed arrangement in which any note can be played either by inhalation or exhalation, the upper pair sounding into one cell and the lower pair into another. Figs. 17, 18 (not shown) indicate a similar four-reed arrangement wherein two reed plates are used each carrying an inhale and an exhale reed. In modified control arrangements Figs. 19 ... 24 (not shown) the air flow is controlled by clack valves which may cover the reed slots, or may cover the entrance to the reed cells. Where four reeds arranged in two pairs are used members of a pair may be accommodated one behind the other on the same reed plate Figs. 25, 26 (not shown) instead of being vertically above one another. The instrument may have chord buttons which are coupled to shafts appropriate to the notes of the chord to be sounded, Fig. 27 (not shown).
