Title: Method of Casting a Light Metal
Inventor: HOWARD MICHAEL ROI
IPC: B22C9/10
Filed: 1968-04-20
Abstract: 1,199,673. Casting processes; making cores. FORD MOTOR CO. Ltd. 20 April, 1968, No. 18785/68. Heading B3F. A light metal, e.g. aluminium article is pressure cast using a ceramic core that has an undercut portion and is breakable to permit removal from the mould after pouring. The core 23 is moulded in a two-part core-box 1 having a plug 22. A metallic spigot 15 surrounds the plug 22 and is incorporated in the core during moulding. The core moulding material is preferably de-aerated friable aluminium silicate which is self-setting. After removal from the mould the core on spigot 15 is fired at 1000‹ C. The spigot has been previously coated with wax or polyvinyl acetate which melts on firing to compensate for the different thermal expansion of ceramic and metal. In Fig. 2, an A1 piston is cast in a two-part mould 29 using the above prepared ceramic core. Molten Al is poured under pressure and gases produced are withdrawn from the mould through the central bore of the spigot via ceramic filled passages 19 (Fig. 1). After solidification, gudgeon 33 and crown 32 cores are removed and the mould 29 opened. The cast cylinder is gripped and the spigot 15 pulled away therefrom. In so doing, projections 34 on the spigot 15 break up the ceramic core part 25 (Fig. 1).

Title: Detecting leaks in pipelines
IPC: G01M3/28
Filed: 1970-04-21
Abstract: 1311993 Detecting leaks in pipe-lines SIEMENS A G 21 April 1970 [22 April 1969] 19127/70 Heading G1S A method of detecting leaks in a flow path along which a gas is flowing, comprising the step of monitoring the variation with respect to time of the difference between gas pressures at the ends of at least one zone of the flow path, the step of examining for an increase in said difference by at least a predetermined amount in a predetermined interval of time when a pressure at the downstream end of the zone is less than a pressure at the upstream end and the subsequent step of indicating that a leak has been detected if in the examining step such a pressure difference increase is detected. As a preliminary step, if a pressure increase in the direction of flow is found, examination is' made for a decrease in the increase of a predetermined magnitude within a predetermined time; if such is found then a leak is also indicated. In order to decrease the number of spurious leak conditions arising e. g. from random fluctuations in pressure or instrument errors being interpreted as leaks, a number of such zones are grouped into a monitoring section, and a leak condition is indicated for the section only when more than a certain proportion of zones within the section each indicate a leak condition. The zones within a monitoring section may overlap one another or be in series. A plurality of overlapping monitoring sections in a pipe-line may similarly be inter-related so that leak indications are given by a section only when adjacent overlapping sections agree. Similarly by determining the pressure pattern in the pipe-line at regular intervals, and comparing successive readings, leak indications will only be given if the trend in time is to indicate a leak in a particular section. An over-all increase or decrease in pressure will prevent particular variations in pressure difference being indicated as leaks.

As the aircraft nears the airport the symbol 22 starts tracking towards aircraft symbol 20 and providing that the aircraft is at the correct speed and altitude, symbol 24 will track down with landing area symbol 22 and with triangle part 26 enclosed within symbol 22. Thereafter deviations from a predetermined rate of deceleration are indicated by movement of triangle 26 relative to symbol 22. When descent commences symbol 29 moves into position to bracket aircraft symbol 20, the rate of descent being adjusted to maintain this relationship, and as the descent continues the size of landing area symbol 22 increases and the symbol moves towards symbol 20 and so long as the aircraft is maintained on its correct flight path the triangle 26 will remain within symbol 22. If the commands of the instrument have been followed correctly the aircraft will be hovering over the landing pad with symbols 22, 26 and 20 coaxial.

Abstract: 442,513. Cathode-ray tubes. COSSOR, Ltd., A. C., Highbury Grove, London.- (Assignees of Ardenne, M. Von; 19, Jungfernstieg, Lichterfelde, Berlin) July 3, 1934, No. 19604. Convention date, July 22,1933. [Class 39 (i)] In order to prevent " origin distortion " the fluctuating deflecting potential is applied to a deflecting plate lying entirely on one side of the electron beam, while different steady potentials are applied to different parts of a plate on the other side of the beam. The Figure shows a tube arranged for two-dimensional deflection having plates 4, 7 to which the fluctuating potential is applied and plates 5, 8 each divided into two parts connected to opposite poles of a battery 6 the mid point of which is connected to the anode 3, or earthed. The parts of the plates 5, 8 connected to the same end of the battery 6 may be connected together inside the tube as shown. In a modification, instead of the plates at steady potential being divided they are made of high resistance material, so that a potential gradient occurs in them. In order to give room for the beam the plates at steady potential may be inclined to the axis of the tube, or when they are in two portions, the portion farther from the cathode is further separated from the other plate than the opposite portion ; in this case the lengths of the two portions should be so chosen that the two sections of the deflector condenser thus formed retain equal sensitivity.

[Class 37] A radio tuning arrangement in which a dial sheet having a number of linear scales adapted to cooperate with a stationary index is carried by a spaced pair of drums, has the tuning knob of the radio geared to one of the drums for moving the sheet in accordance with the tuning of the radio, and a spring element is attached to the other drum for holding the dial sheet taut and for winding the sheet thereon, a friction member being attached to the first drum for stabilizing the operation thereof. Figs. 1 and 3 show the invention applied to a control unit for operating remotely situated radio apparatus on an aircraft, the unit being contained in a dustproof box 11 closed by a front panel 10. A knob 15 controls a function switch which makes the necessary connections for four different kinds of direction finding using a choice of aerials. Knob 18 operates a volume control which has in circuit a meter 20 to give an indication of the distance of the station being received. Knob 25 controls a band selector switch 26 giving a choice of six wave bands. The leads from these controls pass to a multiple socket member 17 with which is associated a multiple plug and cable (not shown) for completing the electrical connections with the remotely situated apparatus (not shown). The tuning of the apparatus is effected by a flexible shaft (not shown) connected to the rear end of a shaft 65 driven through reduction gearing 64, 54 by a tuning knob 51. The tuning scales are carried on a sheet 31 wound on two drums 45, 46 and are visible through a transparent window 32 a dial lamp (not shown) being provided.
