Title: Improvements in apparatus for observing and measuring of pressures within organs of the human body
Inventor: THOREN HERBERT
IPC: A61B17/44
Filed: 1956-09-11
Abstract: 839,327. Sphygmographs. VACUUMEXTRACTOR A.B. Sept. 11, 1956, No. 27723/56. Class 81 (2). An appliance for measuring internal pressures comprises a membrane 5 stretched across a chamber 2, having ports 3, 4. When the membrane is pressed against a part of the body compressed-air is admitted through the inlet 3 and, when the pressure within the chamber equals that within the body, the membrane is moved away from the outlet 4 and no further rise in pressure is possible. The maximum pressure reached thus indicates the internal pressure and may be read by means of a suitably placed gauge. The appliance may be used on the abdomen to indicate muscular contractions during childbirth and may also be incorporated in a suction cup.

Abstract: 533,175. Vibrating moulding machines. SESSIONS, A. G. Oct. 13. 1939, No. 27868. [Class 87 (ii)] A vibrating machine for consolidating materials, such as concrete, in moulds, comprises a conveyer adapted to support the moulds for movement from a feed station to a vibrating station in the machine and thence to a delivery station, a vibrating structure, elements coupled to or forming part of the vibrating structure and adapted to support the mould at the vibrating station, and means for moving the said elements vertically to cause them to engage the mould and raise the same from the conveyer, the said elements then supporting the mould free of the conveyer and transmitting the vibrations of the vibrating structure to the mould. Figs. 1 and 3 show such a machine with a roller conveyer in three parts 7, 4, 8. The spring-mounted vibrating member 20 is actuated by a unit 24, and carries members 25 which can be raised, by rotating the shafts 31 and cams 32, so as to lift the mould M clear of the rollers 6 and vibrate it vertically. Means for locking the cams may be provided, and the mould may be held firmly in raised position, while being vibrated, by resilient clamping members 42 on the frame 20. Figs. 6 and 7 show a modification in which the unit 24 is fixed directly to the mould supporting members 55 which are resiliently supported on a sub-frame 50, and the latter can be raised by actuating the cams 52. The clamping members 42, in this modification, are lowered, to meet the mould, as the latter is raised from the conveyer. Links may be provided, instead of cams, to raise the mould supporting elements, and co-operating bearing surfaces may be provided to support the elements in their raised or lowered positions, and also to transmit horizontal components of the vibrations.

Abstract: 625,256. Discharge lamps. PENNYBACKER, M. Oct. 25, 1945, No. 28245. Convention date, Dec. 23, 1944. [Class 39 (i)] A discharge lamp has two main electrodes 2, Fig. 1, and a conductive starting strip in the form of a straight channel unconnected to the circuit and provided with a porous insulating coating in the form of discrete particles ; the coating allows the passage of a glow discharge at starting, but resists the passage of any current after the main discharge has started. The starting strip 3 is of iron, nickel-plated iron, magnesium, aluminium, or of an alloy, coated with aluminium oxide, magnesium oxide, or with a fluorescent material, e.g. silicates. The metal may act as a reflector and the coating may be transparent, translucent, or reflecting. The strip may be elastic and is inserted into the tube as a separate unit ; it is preferably an exact semi-cylinder, but may extend for more or less than 180 degrees around the circumference of the tube ; in another form, Fig. 2B (not shown), it is V-shaped. Alternatively, the strip is of less elastic material and is held in place by a coating of adhesive material between it and the tube wall. The tube wall may be of quartz or of glass which transmits ultra-violet, and may be provided with fluorescent material or with a filter. The strip may also have a rear coating of porcelain enamel, and is placed at a predetermined position with respect to the contact pins so that it is in the correct position when the lamp is inserted into its socket. The power supply transformer has a poor regulation characteristic. The electrodes may be hot or cold starting. A plurality. of starting strips separated by gaps may be used. If two starting strips are used, Fig. 4 (not shown), their lengths may be in the ratio of 39 : 46. In all forms, the coating is applied by spraying, dipping, or dusting. The filling may be argon or an argon-neon mixture, at 3 mms., or at 1-5 mms. with the addition of mercury vapour. The Specification as open to inspection under Sect. 91 describes a form, Fig. 3 (Cancelled), in which the electrodes 11, 12, are separated by a partition 14 formed of metal, or of glass or mica coated with conductive material, and having an outer covering of insulating material. The insulating outer covering may also be fluorescent. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,146,738. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MFRS. Ltd. 24 June, 1966, No. 28298/66. Heading H1K. Photoresist masking and etching is used to form an aperture in a thermally grown oxide layer on a P-type silicon wafer. The heated wafer is then exposed to an atmosphere containing arsenic trichloride, tetraethoxy silane, and oxygen to deposit a glassy arsenic-doped silicon oxide layer or the previous oxide masking layer. Exhaust gas from the deposition chamber is passed through glass wool filters to remove particulate arsenic trioxide and through aqueous potassium hydroxide to remove halogen. The wafer with its doped oxide is then heated in dry oxygen to diffuse arsenic into the wafer through the oxide mask to form a highly doped N-type region. The wafer is etched with nitric acid to remove remaining arsenic from the oxide and then with hydrofluoric acid to remove the oxide itself. Further processing to make a device may include e.g. epitaxial deposition and further masking and diffusion. The arsenic profile will remain substantially unchanged if the temperature used in these processes is lower than that used in the initial diffusion. Arsenic tribromide may replace the chloride.

Abstract: 1,222,677. Photo-electric distance measuring. ELTRO G.m.b.H. & CO. GES. FUR STRAHLUNGSTECHNIK. 14 June, 1968 [28 June, 1967], No. 28351/68. Heading H4D. [Also in Division G1] The amplification factor of a photomultiplier, e.g. in a laser distance measuring device is varied in dependence upon the intensity of the background radiation. The photomultiplier 4 receiving reflected laser pulses through a field stop 1, lens 2 and filter 3 produces corresponding pulses together with noise proportional to the intensity of background radiation. A pulse counter 7 determines the frequency of noise pulses of sufficient amplitude to cause a false indication if they arrive at an appropriate time. The signal from the counter 7 controls a setting member 9 for the photomultiplier H.T. transformer 10 so that the photomultiplier gain is always such that there is a predetermined probability of a false indication occurring, and the sensitivity of the apparatus is always at the maximum permitted by the prevailing background radiation. The probability of false indication is selected by a potentiometer 11 and the selected level indicated by meter 8. In a modification Fig. 2 (not shown) the inputs to counter 7 is derived from a separate photodiode instead of the photomultiplier 4.
