[A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 20, 1949.] Class 78 (4). The trolley shown in Figs. 3 and 4 has auxiliary wheels 30 as well as front and rear wheels 26, 25 and is drawn by power means on to the chassis shown in Fig. 1 which includes portions 4<SP>1</SP>, 4<SP>2</SP>, 4<SP>3</SP>, 4<SP>4</SP> of L or inverted T section inclined first upwardly from the rear and then downwardly. As illustrated the chassis is a semi-trailer and chains 8<SP>1</SP> by which the trolley, which can carry a freight container, is moved, are driven through gearing from a shaft 9 driven by the tractor. The trolley is first drawn to the rear of the chassis by auxiliary chains connected to the chains 81 and to a hook 31, Fig. 5, pivoted to a frame 32 which is pivoted at 33 to the trolley. This brings the spindle on which the hooks 31 are pivoted into engagement with hook-shaped links, shown in Fig. 7, and forming part of the chains 81. Guide rollers 15 on the same shaft as the rear sprockets 8 of the chains 81 assist in raising the trolley on to the chassis. The trolley is automatically steered into alignment with the chassis by wheels 27, Fig. 3, which engage the outer side of the vertical flanges of the longitudinals 1 of the chassis. so that if one wheel engages before the other it rotates a sprocket 28 which, through a chain 29, moves a sliding frame carrying the rear wheels 25 of the trolley laterally in the direction necessary to align the trolley with the chassis. Hooks 35 at the front of the trolley may receive towing connections by which the trolley can also be aligned with the chassis. The Specification as open to inspection under Sect. 91 also describes an arrangement in which hingedly connected ramps on vehicles between which a container is to be transferred are tilted conjointly to facilitate pulling the container over rollers on the ramp by means of cables. The operation of this construction is not clear from the Specification and the subject-matter does not appear in the Specification as accepted.

Abstract: 764,284. Glass manufacture. VERRERIES CHARBONNEAUX. Feb. 3, 1955 [Feb. 8, 1954], No. 3192/55. Class 56 In the operation of a mould for a glass article, e.g. an insulator, having projections and/or recesses which during shrinkage of the article in the mould tend to bind upon the pressing-die, an outer collar 4 is first applied to the bottom mould 1 to prevent ejection of glass, the central parts 2, 3 of the die continuing to descend to form the article, after which the parts 2, 3 are withdrawn slightly from the article to permit the shrinkage before the die is completely raised. The bottom mould 1 is in two parts and is movable by a fluidpressure motor 8, 10 to a position X in which it receives a gob from the trough 7, to a position Y in which it is aligned with the die, and to a position Z in which the article is discharged. The die is reciprocated vertically by a motor 24 and swinging links 18 connected to a crosshead 15 on vertical guide rods (not shown). When the collar 4 engages the mould 1, further motion compresses springs 57 on rods 55 which carry the collar from a plate 25 which is adjustably secured to the crosshead 15 by nuts 15a, 15b. The part 2 of the die is movable vertically, relatively to the plate 25, by a fluid-pressure cylinder and piston 29, 30, the piston being fixed relatively to the plate 25 and the cylinder movable to the extent permitted by adjustable lock-nuts 40, 41. When the .collar 4 is arrested by the mould 1, fluid pressure below the piston 29 keeps the part 2 of the die in its effective pressing position. The application of pressure to the space above the piston 29, raises the cylinder 30 and the part 2 of the die to permit the shrinkage. The plunger 3 which forms the central screwed recess of the insulator is carried on a central shaft 42 having a screwed upper end to engage a non-rotatable nut 43 and a key-way 47 which is slidably engaged by a feather 48 in a gear wheel 49. This gear wheel is driven reversingly by a shaft 53 driven in synchronism with the other parts of the press. When the wheel 49 is rotated the screwed plunger 3 is rotated and moved up or down, according to the direction of rotation. As the part 2 of the die is slightly withdrawn, the screwed plunger 3 also is withdrawn slightly, from the cavity, during which action the crosshead 15 is locked to its guides by an hydraulic braking device. This device is released before the press head is fully raised. In a modification in which the plunger 3 is smooth, i.e. not screwed, it is not rotated.

Abstract: 946,111. Electric correspondence control systems. JOSEPH LUCAS (INDUSTRIES) Ltd. Jan. 19,1961 [Jan.29, 1960], No. 3224/60. Heading G1N. The fuel supply to a gas turbine engine is controlled during acceleration or deceleration in accordance with empirical relationships where Ni is the desired speed, Na the instantaneous speed, P the pressure and T the temperature of the air intake to the engine compressor. The air intake temperature signal, obtained by temperature sensitive resistor 10, and the instantaneous speed signal, measured by a tachogenerator 2, are combined at 11 to produce the positive signal f(Na/#T) and the negative signal f<SP>1</SP>(Na/#T)), one of which is allowed to pass back-toback diodes 13,14 when the desired speed Ni, manually selected at 17, is different from the actual speed Na, as compared at 18. The function signal is now multiplied by #T at 15, the temperature being measured by a second temperature sensitive resistor 9, multiplied again by P at 16, the pressure being measured by a pressure sensitive element 8, and integrated at 3. The resultant signal, representing the ideal speed change without causing the engine to fail, is compared at 1 with the actual speed Na from the tacho-generator 2, any difference being amplified at 4 to energize a motor 5 controlling the fuel supply valve 6.
