Inventor: BERNE JEAN
IPC: E21B7/12
Filed: 1963-07-23
Abstract: 1,066,774. Boring earth &c. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. July 23, 1963 [July 24, 1962], No. 29180/63. Heading E1F. A sub-aqueous well is drilled by means of a drilling head carried by a flexible: tubing, a substantially constant force being applied at a point B to a lower preselected length of tubing and the weight of the upper part of the tubing being supported from the drilling station N. The constant force is applied by a float E which sinks as drilling proceeds and as tubing is lowered intermittently or continuously from the station. To prevent crushing of the float the cable connecting it to the point may be extended as drilling proceeds or the float may be flexible and filled with a fluid. The lengths of the lower preselected length of tubing may be fixed, or may be adjusted continuously or intermittently as drilling proceeds.

Title: Improvements in or relating to analogue-digital converters
IPC: H04B14/04
Filed: 1959-08-26
Abstract: 918,987. Analogue-to-digital converters. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 26, 1959 [Aug. 29, 1958], No. 29191/59. Class 40 (1). A varying voltage is sampled by a switching device and the samples applied as pulses to the primary 2 of a transformer which has a number of secondaries 3a-3k having different ratios to the primary winding. Each secondary has a series of potentiometers 5 of different value so as to produce different fractions of the secondary signal and each such fraction is applied to a transistor threshold circuit such as 4a which responds when the applied signal exceeds a certain preset value. The threshold voltage is preset by potentiometer 11 which applies a corresponding signal to the base of transistor 10. When the value is exceeded this transistor conducts and a signal is produced at the collector of transistor 12. All threshold circuits respond which are set to a value below the applied signal and the rest do not. The resistor 14 may be replaced by a relay the contacts of which are connected in a circuit so that only the line is energized corresponding to the highest valued threshold device responding. This may light a lamp indicating the value of the applied signal.

Title: Improvements in and relating to incandescent welding with electricity
IPC: B23K11/04
Filed: 1919-11-24
Abstract: 154,067. Gale, F. G. Nov. 24, 1919. Furniture.-In a process of electric welding the end of one tube to the side of another tube of greater cross-sectional area without preheating, particularly for making bedstead frames, the tubes are held adjacent to one another so as to provide a sparking contact between them and thus raise the end of the smaller tube to melting or burning temperature, and the smaller tube is moved towards the larger tube as it melts away so as to maintain the sparking contact, and the parts pressed together as soon as the larger tube reaches welding temperature. The larger tube is subjected to the heat developed by the current due to its resistance and also to the excess heat developed in the end of the smaller tube. The point of highest temperature is at the extremity of the smaller tube and not at some distance away as would be the case if the parts were in contact. The top and bottom tubular rails may in this way be welded to tubular bedstead posts and the vertical tubular rails to the top and bottom rails. In the form shown, Fig. 2, a small square tube 4 of thin gauge is welded to a larger tube 2 of thicker gauge. Circular or other tubes may also be welded in this way.

Filed: 1920-10-16
Abstract: 158,532. Hult, C. A. Feb. 6, 1920, [Convention date]. Valve gear; valves.-In an engine having two annular pistons 4, 5 working in an annular cylinder, cams 14 on the shaft 19 have shaped surfaces to give two complete fourstroke cycles for each revolution of the shaft. The admission and exhaust are controlled by a sleeve 29, Figs. 1 and 4, surrounding the shaft and having a central flange 30 with two valve seating surfaces 31, 32. These surfaces bear on two spring- pressed sleeves 33, 34, whose movement is limited by flanges 58 on extensions 52 carried by the cylinder covers. The admission movement of the valve sleeve 29 is effected by the roller 46 on the shaft and projection 45 on the sleeve, the gas passing from the inlet 38 through the space 35 between the two sleeves 29, 33 and thence past the valve head to the combustion space 27; during this movement the sleeve 33 is stationary. The exhaust is effected similarly by the cam 49 and projection 48, the exhaust outlet being at the opposite side to the inlet. A hollow cylindrical slide valve surrounding the shaft may replace the beat valves above described, this valve being similarly actuated.

Abstract: 1355421 Moulded-in filter element ABBOTT LABORATORIES 23 June 1971 [8 July 1970] 29523/71 Heading B5A [Also in Division B1] A filter for the air inlet port of a disposable intravenous fluid administration system comprises a tubular plastics body integrally moulded around a section of filter material 20. A plurality of such filters are moulded on to a single sheet of filter material 20 (Fig. 2) which is initially laid on an apertured plate 32, resting on plates 34 and 36 which support sleeves 42 extending into each aperture to define the lower parts of mould cavities. The passage 5 is defined by core pins 58 and 72, extending respectively up to the material 20, and bore 74 in upper plate 64 defines the upper part of the mould cavity. Plastics is injected to fill the mould cavity as shown, and plates 64, 66, 46, 48 and 50 are lifted so that sleeve 56 pushes the filter body out of sleeve 42, pin 58 being held down against plate 52 by spring 62. The injection pressure forces plastics through the material 20 to unite the body portions on both sides thereof. The individual moulded bodies are separated from their common sheet 20 by a punch and trim die (Fig. 3, not shown) having apertures corresponding to those in the mould plates to cut all the bodies from the sheet at once.

Title: Improvements in or relating to light condensers and projectors
IPC: H01K7/00
Filed: 1929-09-30
Abstract: 320,019. Soc. Anon. des Etablissements Ouvrard, Villars et Perez Reunis, (Assignees of Soc. des Etablissements Gaumont). Sept. 28, 1928, [Convention date]. Bulbs; residual gases.-The brightness of the field illuminated by a source of light is increased by the use of a trumpet shaped reflector by which the beam emitted is partially reflected so that it emerges as a slightly convergent or divergent beam. This reflector is used in conjunction with a source of light enclosed in a bulb the inner surface of which is also reflecting. The device is applied to optical projection apparatus, motor car head lights, &c. In the usual form, Fig. 1, the light source F is contained in a bulb having two inner reflecting surfaces A, B, C and A, F1, C the first being elliptical and the second spherical, so that the whole of the emitted rays is ultimately projected through a clear aperture L, K into the trumpet-shaped reflector L, M, N, K, part of the rays passing directly through it and part being reflected until their angle to the axis is less than that of the reflector. In connection with these reflectors electric bulbs are used in which channels C1, C2, Fig. 4, are provided for the flow of inert gases to prevent blackening near the source of light or the lamp may be formed as in Fig. 3. In a modified form of lamp the reflector 22 is incorporated in the bulb and the outer end 23 of the bulb is formed as a converging meniscus lens. A non-dazzling motor car light is formed by a reflector lamp, Fig. 10, and a flattened trumpet-shaped reflector giving a broad horizontal beam. The reflector may be made of a number of glass blocks, Fig. 8, having a curved end surface so that the beam is caused to converge. When used with an ordinary lamp the trumpet-shaped reflector is fitted at the lamp end with a conical reflector, and an additional curved reflector is provided at the back of the lamp so that a larger proportion of the rays are utilized by the principal reflector. Such an arrangement is used in connection with an ordinary optical projection apparatus, Fig. 9, the reflector 12 being fitted with the conical reflectoras shown.
