Abstract: 656,833. Helicopters. STALKER, E. A. Oct. 16, 1946, No. 30797. Convention date, Nov. 2, 1945. [Class 4] In order to allow a helicopter rotor to operate at an advance ratio greater than unity, i.e. with a translational velocity (Va) exceeding the blade tip peripheral speed (Vp), the blades are automatically adjusted about their spanwise axes during rotation to ensure that positive lift is generated by each blade when retreating.

Title: Starting of internal-combustion engines
IPC: F02N1/02
Filed: 1930-10-15
Abstract: 363,754. Turning-gear. LISTER & CO., Ltd., R. A. and SANDERS, A. F., Victoria Iron Works, Long Street, Dursley, Gloucestershire. Oct. 15, 1930, No. 30837. [Class 7 (v).] In an engine having turning gear and means for relieving compression, starting is assisted by an auxiliary flywheel 9 mounted on a shaft 8 located against endwise movement and carrying a pinion 12 slidable into engagement with teeth 7 on the engine flywheel 6 and automatically disconnected when the engine is running, the automatic disconnection being assisted by mounting the pinion on helical splines. 11 or by providing the pinion and the main flywheel with helical teeth. The movement of the pinion into and out of engagement is effected by a fork 15 connected by a link 16 to a fork engaging the stem of the starting handle. Disengagement when the engine begins to fire may be facilitated by connecting the flywheel 9 to the shaft 8 by means of a centrifugally released clutch disengaging at a predetermined speed. The clutch comprises friction discs 21 held in engagement by springs 23 and disengaged by weighted arms 25 each having a claw 27 for engagement with a collar 28 on the hub 20 of one of the discs 21, which is splined on the hub 19 of the other disc. For an engine started by an electric motor, the toothed ring 7 on the flywheel 6 is engaged by the pinion of the electric starter as well as by the pinion 12.

Title: Improvements in or relating to systems for the electrical transmission of signals to railway locomotives
IPC: B61L3/12
Filed: 1936-11-11
Abstract: 468,332. Electric signalling systems. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Nov. 11, 1936, No. 30841. Convention date, Nov. 11, 1935. [Class 40 (i)] [Also in Group XXX] A signalling arrangement for railway shunting yards in which signals are transmitting from a central control point is provided at various local points in the yard with means for causing an emergency signal to be transmitted and any previously set up signal to be cancelled. For example, different audible code signals denoting " stop," " back," " forward," may be transmitted to a shunting locomotive, by means of cams 17 ... 19 periodically interrupting the modulation circuit for a wireless signalling system 1. The control tower operator transmits the signal " back " by depressing a button 44 to pick up a relay 39 which closes its contact 36 whereby a relay 24 is picked up as soon as a cam 26 closes a contact 30. The relay 24 remains up so long as a further cam 27 closes a contact 33, the stick circuit including a contact 55 of the relay 24 and the winding of a relay 42 ; a front contact 21 of the relay 24 closes a point in the modulation circuit and the cam 18 gives the " back " code form to the audible signal. The pick and stick circuits for the push button relays 38 ... 40 include front contacts 90, 74 of a relay 75. If an emergency arises any one of a number of local pushes 76 ... 78 spread about the shunting yard is depressed and remains locked down. Such action de-energizes the relay 75 which at its back contact 86 picks up the relay 23 when the cam 26 closes contact 29. The relay 23 remains energized, together with the series relay 42, so long as cam 27 closes contact 32. Front contact 20 of relay 23 closes a point in the modulation circuit and the cam 17 gives the " stop " code form to the audible signal. Further, the front contact 41 of the relay 42 energizes a vibratory relay 88 over a back contact 87 of the relay 75 ; such vibratory relay 88 gives an alternating pitch to the audible note by periodically switching out the condenser 66 so altering the periodicity of the modulating circuit. Thus the emergency operation causes an audible signal of the " stop " code form and of a special pitch character to be transmitted. Any previous signal transmission set up in the tower is connected since the pick and stick circuits of the push buttons relays 38 ... 40 are opened at the front contacts 90, 74 of the now deenergized relay 75. When a local push 76 ... 78 is depressed it can only be released by a special key. Lamps 79 ... 81 adjacent the pushes and lamps 82 ... 84 on a miniature diagram in the tower are lit to indicate the particular push operated. A checking circuit energized by the aerial current sounds a loud-speaker 11 and lights a lamp 63 in the tower.

[Class 98 (ii).] A machine for applying colouring liquids or varnishes to opposite sides of a kinematograph film, such as a subtractive two-colour film, is provided with two sets of rollers, brushes &c., for treating the two sides of the film in succession, and with means for permitting each roller &c. to be displaced individually into and out of contact with the film. As shown, the film 12 is fed from a reel 11, over a sprocket 13 and guide rollers 10, 9, into engagement with rollers 3 which transfer treating liquid from troughs 4 to one side of the film ; and is then fed by sprockets 17, 19 and over guide rollers 9<1>, 10<1> into engagement with a second set of rollers 3<1> which transfer treating liquid from troughs 4<1> to the other side of the film. A sprocket 20 delivers the film to a take-up reel. Spring- urged rollers 14, 22 press the film against the sprockets 13, 20. The spindles 2 of the rollers 3, 31 are guided in slots 7, 7<1> in the machine frame, and are carried by pivoted bell-crank levers adapted to be locked in one or other of two positions, whereby any one roller may be moved by hand into or out of engagement with the film.
