Title: Improvements in electro-optical measuring apparatus
Inventor: LEUSCHNER HORST
IPC: G01B11/04
Filed: 1966-12-09
Abstract: 1,115,950. Measuring dimensions. LICENTIA PATENT - VERWALTUNGS G.m.b.H. 9 Dec., 1966, No. 55301/66. Heading G4H. To measure the width of material B (Fig. 1) a fixed plate 1 having a curved slit 4 conforming to the equation with respect to the point A and an axis parallel to the edge of the material E through the point A is positioned on the material B, one or more discs with slits 2A, 3A (Fig. 2), being rotatably positioned above the plate 1 so that a counter 13 is enabled to start counting clock pulses when the rotating discs pass over the position X in the slot 4. In one embodiment in which the material is either incandescent or hot enough to emit infra-red radiation a light conductor 5 collects light passing through the slits and conducts it to a transducer 6 or a transducer responsive to infra-red radiation is employed to open a gate 11 as the slits 2A, 3A pass over the edge of the material E to enable clock pulses from an oscillator 10 to be accumulated in a counter 13, the gate being closed either when the slits pass over the opposite edge of the material or when the slits are aligned with a hole 8 in the plate 1 so that a transducer 9 is enabled. In this case, that is when the width of the material is greater than the width of the slit 4, a further similar scanning means is required together with further gating and counting means, the width of the material being represented by the counts in both counters plus a known constant value representing the distance between the two scanning means. If the material does not generate light the scanning means is made responsive to an opposite change in the light intensity. Instead of the oscillator 10 the slit 4 may have a screen behind it so that a series of pulses are sent to the gating means 11.

Title: Method and apparatus for radiating low-frequency radio waves
IPC: H01Q9/38
Filed: 1973-12-03
Abstract: 1390009 Aerials WESTINGHOUSE ELECTRIC CORP 3 Dec 1973 [12 Dec 1972] 55910/73 Heading H4A In propagating radio waves of a frequency not exceeding 300 kHz from an aerial which is adapted to be deployed from an aircraft and to be connected toward its upper end to a transmitter, said aerial has length substantially equal to one-fourth of the operating wavelength of the transmitter, and at least part of it is suspended vertically from the aircraft. At the lower end of the aerial are means for providing a lowresistance path to a body of water having a conductivity at least equivalent to the presence therein of 1 part per 1000 of NaCl, whereby it acts as a ground plane. In one embodiment an aerial element 18, Fig. 2B, extends from a helicopter 10 to the sea 21 where it terminates in a drogue 20, which provides a good electrical connection. The aerial element 18 may have a diameter of # to ¢ inch and be made of a mechanically strong material such as steel or fibreglass, with a conductive coating of copper or aluminium. It is lowered from the helicopter by means of a winch, and passes through an insulating bushing 22. One terminal of a radio generator 26 is connected through a coupling unit 24 to the element 18, and the other terminal thereof is connected to the shell of the helicopter. A counterpoise 32, which enables the length of the element 18 to be reduced below #/4, is deployed from the helicopter, one end being connected to the shell thereof, and the other end being terminated in a conductive shell 34 of greater diameter, to reduce corona effects. In another embodiment, the counterpoise is omitted (Fig. 2A, not shown) and in another it is passed through an insulating bushing to one terminal of the radio generator, the other terminal of said generator being connected via the coupling unit to the helicopter shell, to which the aerial element is also connected (Fig. 2C, not shown). The drogue 20, Fig. 4, has a lightweight housing 44 in which is a solenoidoperated door 54 controlled by radio signals from the helicopter for admitting water when the drogue is lowered and for releasing water when it is raised. A conductive coating 62 is provided on the outside of the body 44, and the element 18 is attached via a universal connector 40.

Abstract: 1433830 Load moving apparatus BRITISH STEEL CORP 10 Dec 1974 [11 Dec 1973] 57337/73 Heading B8J [Also in Division F2] Apparatus for moving a load comprises four jacks 1, each arranged on a track 9 on a base 8. Each jack 1 bears on a metal pad 2 on the underside of which is bonded an elastomer layer 3 having a peripheral skirt 4. In operation pressure fluid is fed to the underside of the elastomer layer 3 slightly dishing it, Fig. 2, and reducing the friction so that the jack 1 can readily be moved sideways. Included in the apparatus is a load supporting frame 11 with three dependant legs 12 mounted astride the base 8. An actuator 14 is connected between the base 8 and the frame 11. As shown the apparatus is used to lift an ingot mould 20 from its parked position on concrete blocks 21 and transport it as required. Fig. 5 shows the frame 11 lifted by actuation of the jacks 1, pressurized fluid being supplied to form a film under the pads 2 whereupon operation of the actuator 14 to its extended position slides the jacks 1 along their tracks 9 carrying the frame 11 and load with them. Fig. 6 (not shown) illustrates that retraction of the jacks 1 allows the frame 11 to rest on its legs 12 whereupon retraction of the actuator 14 drags the base 8 along under the jacks 1 to complete a walking movement. As shown the jacks 1 and the actuator 14 are hydraulically operated from a power pack 17 and the fluid pressure films are of grease supplied from a pump 18, though air, gases, or other liquids may be used. The fluid pressure films may alternatively be formed between the jacks 1 and the frame 11.

In a method of vacuum casting high purity precision metal parts at least one heated mould 22, 23, is located in a closed vessel 11 evacuated by means 16 and the casting in the mould cavity 25 is cooled in such a way as to produce an upwardly advancing solid-liquid interface which progresses slowly and terminates in the casting in a blind riser portion 30 situated in the uppermost part of the mould cavity 25. In the embodiment described a plurality of mould parts 22, 23, 24 are used in stacked relationship and carried in a yoke member 20, the mould cavities being interconnected by a feed channel 29 and are supplied with molten metal from a crucible 35 located directly above the moulds. The moulds and the crucible are heated by induction coils 46 and 45 respectively, the heating being controlled to produce the desired solidification of the casting. Plug members 41 and 36 respectively are actuable to permit the supply of material from the hopper 40 to the crucible and from the crucible to the mould cavities. The mould and yoke parts are made from spectrographically pure graphite to prevent contamination of the resultant castings. The mould cavities may be provided with recesses 50 for inserts or core portions so as to facilitate the changing of the shape of a particular part of the casting. These inserts may be of metal which may through surface fusion become incorporated in the resultant casting. The construction of the mould is such as to permit the mould parts to be reused.
