Title: Improvements in the feeding of constant level float chambers for carburetters
IPC: F02M1/00
Filed: 1954-04-14
Abstract: 747,896. Carburetters. VIEL, L. L. April 14, 1954 [April 23, 1953], No. 10952/54. Class 7(3) In a carburetter especially for autocycles small motor cycles or low power industrial sets in which the fuel inlet valve 5 of the float chamber Y opens in a direction opposite to that of the fuel flow the fuel on its way to the fuel inlet valve passes a restriction such as a calibrated orifice 19 in a diaphragm 18. The diaphragm may be replaced by a choke in the fuel pipe or by any other device for restricting the flow of fuel. The restriction prevents the flow of fuel exceeding a value slightly greater than that required for full output of the engine. This causes the needle valve to rise intermittently consequent on rapid increase of the fuel demand and prevents fouling of the valve seating.

Title: Improvements in or relating to Line Feed Mechanisms for Electrically-Operated Typewriters, Teleprinters and the like
IPC: H04L13/18
Filed: 1968-03-07
Abstract: 1,178,076. Typewriters. SIEMENS A.G. 7 March, 1968 [8 March, 1967], No. 11053/68. Heading B6F. Variable line-spacing arrangements.-Line feed mechanism for electrically-operated typewriters includes a lever 4 having a gear segment at one end engageable with teeth on a platen roller feed wheel 7, the lever 4 being oscillated about a displaceable spindle 6 and reciprocated towards and away from the wheel 7 by an eccentric 2 mounted on a rotatable spindle 1 and engaging a yoke 8. A second lever 5 may engage the wheel 7 when the first lever 4 is displaced therefrom. The levers 4, 5 are urged towards the wheel 7 by springs 11, 10 respectively. Displacement of the spindle 6 causes variation of the lever arm ratio and consequently permits variation of the line spacing. The wheel 7 may be held in a set position by a weak detent arrangement. In the stationary period the levers are disengaged from the wheel 7, thus permitting manual rotation of the platen roller.

Levers 135 extending from the ends of the tubes 134 engage a fixed cam 133 to cause the fingers to engage and lift the hay from the ground and then deliver it, as the discs 132 move round, over stripper plates 138 and beneath wind-guards 141 to the transverse conveyer E. The elevator D may be raised or lowered as a whole by a lever connected by a link 155 to arms 128 in which the drive shaft 129 is journalled. The wad board 61, Fig. 3, actuated through link means by a connecting rod 26 which drives the packing plunger 24, presses hay, fed to the wad board well 23 by the conveyer E, down through the well into the path of the packing plunger 24 whence a bale is pushed into the packing chamber F, the sides of which includes hinged adjustable pressing bars 30. L-shaped needles 100 mounted on a vertical shaft 102 at one side of the packing chamber F are swung, by linkage mechanism, Fig. 1, operated by a crank 99, to carry twine or wire through slots 101 in the face of the packing plunger 24 across the bale to tying mechanism. The drive shaft 129 of the pick-up elevator D is connected to a shaft 82 driven by a chain 81, which chain is driven, either by a sprocket on an overrun clutch 79 on a baler wheel B, or by a sprocket 80 on a shaft 72 driven through a slip clutch 77 from the motor C, according as to which means tends to drive the chain 81 faster.

Class 40(3) Photo-electric control apparatus comprises two photo-cells 5, 6, each responsive to light from a source 1 and arranged to operate relays A, B, respectively, if necessary via amplifiers, when illuminated beyond a predetermined limit, the relays A, B, having contacts a1, b1, in series in a main control circuit, and make-before-break contacts a2, b2 in a normally closed safety circuit which operates alarm, control or devices if the relays assume unlike conditions. To prevent the safety circuit being broken owing to the failure of the relays to release simultaneously contacts a2, b2 are shunted by the break contacts c of a third relay (C,) and relay A is arranged to release ahead of B, contacts c being kept closed until B falls back by the short-circuiting of relay C by contacts b3. Relay C is sufficiently sluggish to allow the safety circuit to be broken if B operates without A.

[Class 51 (ii)] Discharging.-In a blast or cupola furnace having separate outlets b, c for metal and slag, solidification of slag in the passage rising from the bottom of the shaft a to the outlet c is prevented by so positioning and proportioning the outlets b, c that the furnace pressure maintains a column 9 of metal extending part way up the rising slag passage. The latter communicates with the shaft a through a horizontal duct the upper side m of which is above the normal metal level so that slag can flow freely from the bath h into the rising passage. The outlet c itself and the rising passage leading thereto may be formed in a box d which can be detached or swung aside on a hinge.

[Class 39 (i)] A mercury or other metallic - vapour rectifier having a gas filling consists of an elongated tube with a dividing wall m separating two anodes c, d, a cathode b, of mercury or other vaporizable metal, and one or more internal starting electrodes a, i, a resistance g, g<1> being included in the circuit of each starting electrode for limiting the current between that electrode and the other electrodes under no-load conditions to a value below that at which a glow takes place, but sufficient to produce ionization. The starting electrodes are connected through the resistances with auxiliary windings f of an auto-transformer e. It is suggested that when the load is applied an arc occurs between a starting electrode and one anode, and causes an arc to be set up between the anodes before the main discharge starts between the anodes and the cathode. In a modification, Fig. 3 (not shown), a separate transformer is connected between a starting electrode and an anode, and the resistance is connected in the primary.
