Title: Improvements in or relating to Means for Supplying Fuel, Water or Oil in Connection with the Engines of Aircraft, Motor Cars, Motor Boats and the like.
IPC: F02M25/022
Filed: 1917-07-05
Abstract: 121,300. Sage & Co., F., and England, E. C. G. July 5, 1917. Direct air-pressure apparatus, automatic.- Apparatus for raising liquid comprises a pump e which produces pulsation in a column of air in the pipe h and causes liquid to rise up the pipe a<1> and pass through the valves b<1>, b<2> into the chamber a. On reaching a certain level the liquid through a float d lifts the valve b<2> and tends to stop the supply of liquid, but, if the level is exceeded, the float closes an air valve d' and produces an air cushion in the chamber a. The chamber may be primed through a funnel c<6>. The apparatus is designed to supply liquid fuel, water, or lubricating oil to the engines of aircraft &c., the pump may be driven by a wind motor f or by the engine.

Title: Improvements in superheterodyne frequency converters
IPC: H03D7/08
Filed: 1948-04-07
Abstract: 636,724. Valve circuits. BENDIX AVIATION CORPORATION. April 7, 1948, No. 9792. Convention date, April 18, 1947. [Classes 40 (v) and 40 (vi)] A superheterodyne frequency converter comprises a crystal-controlled cathodecoupled oscillator in which a radio frequency input signal is applied to the control grid of the first valve, and a difference frequency is taken from the anode circuit of the second valve. The cathodes of valves 10, 11 are connected by a piezoelectric crystal 15 having a series resonant frequency fo/n, and by an inductor 14 which is parallel resonant with the capacity of the crystal holder at a harmonic fo of the crystal frequency. An inductor 16 in the anode circuit of valve 10, together with distributed circuit capacities and resistor 17, form a circuit whicli is broadly resonant at the oscillator frequency fo. Radio frequency signals of frequency fr from source 21 are applied to the grid of valve 10, and a difference frequency signal fi=fr - fo is taken across a circuit 18 tuned to this frequency. When the difference between fr and fo is too great for the pass band of circuit 16, 17, this circuit may be given a double resonant peak by means of a parallel tuned circuit which is either coupled to inductor 16 or connected between circuit 16, 17 and the anode of valve 10.

Abstract: 1378111 Gas storage tank BRIDGESTONE LIQUEFIED GAS CO Ltd 28 Feb 1973 [13 March 1972] 9824/73 Heading F4P A low temperature, liquefied gas tank, e.g. in a tanker ship, comprises a rigid outer vessel 2, an insulating layer 3, e.g. of pearlite concrete, or sulphur, and an inner membraneous vessel 4, e.g. of thin plates of steel or aluminium, the   inner vessel 4 being constructed within the outer vessel 2 and then being urged inwardly at its flat side walls by an amount to form sufficient slack corresponding to the contraction of the inner vessel in its low temperature operating condition, the space left between the inner and outer vessels then being filled with heat insulating material to form the layer 3. As shown, the tank has two inner vessel membranes 4, 5, the bottom portions 4a, 5a first being laid on a protecting plate 13a covering insulating layer 12 and scaffolding and jigs then being used to assemble side walls 4b, 5b. A portion of side wall 4b is omitted initially to give access for welding and inspection of both membranes. The top portions 4c, 5c of the membranes are prefabricated with the vessel deck 6, insulating layer 10, protecting plate 13c and membrane supports 9. To provide the required slack in the tops of the membranes the deck assembly may be either suspended higher than its final mounting position while membrane portions 4c, 5c and 4b, 5b are joined, or mounted in its final position with portions 4c, 5c and 4b, 5b overlapping. After assembly of the membranes, protecting plate 13 is urged against side walls 4b, 5b by expansion means 15, e.g. hydraulic jacks, to provide the required slack, and the space between vessel 2 and plate 13 is filled with insulating material, jacks 15 being removed as the insulating layer builds up. The membraneous vessel interior may be pressurized with gas to prevent pushing inwards of its side walls by the insulating material before it sets.

Title: Device for combining long-length articles
Inventor: IDEI MASARU
IPC: B65G57/09
Filed: 1994-01-10
Abstract: PURPOSE:To shorten the time per cycle required for combining long length articles by accumulating long length articles in an accumulating zone, simultaneously with a work for combining the long-length articles in a combining zone. CONSTITUTION:When a long length article A is conveyed after a separating lever 5 is lowered, the long length article A abuts against a stopper 6 in an accumulating zone X, and accordingly, a predetermined number of long-length articles A are accumulated in a condition such that their projecting parts T1, T2 abut against one another. Then the long length articles A are lifted up by a rotary traverser 2, and are shifted obliquely downward toward a combining zone Y. In this phase, when a comb-like member 3 is elevated, the long length articles A1, A3,... in odd rows are received by a slide skid 4 while the long length articles A2, A4,... are received by the comb-like member 3. In this condition, the slide skid 4 is moved by a predetermined distance in a direction reverse to the conveying direction so that the long length article Al is made to abut against a stopper S, and when the comb-like member 3 is lowered so as to move it in the same direction by a predetermined distance, the long length articles A are set in a condition such that their projecting parts T1, T2 are completely superposed with each other.
