Abstract: 1,257,114. Electro-medical apparatus. E. R. JOHN and R. LAUPHEIMER. Nov. 25, 1969 [Dec.11, 1968], No.57572/69. Heading G1N. In an instrument for detecting life in a patient, the signals from an EKG and from an EEG are monitored. As shown, the EEG provides evoked response signals due to visual, audio and shock stimulators 42, 43, 44 to a data scan 14 which sequentially applies the signals via an amplifier 19 to a data scan 21 and a data scan 60. The EKG also applies its amplified output signal to the data scans 21 and 60. The data scan 21 sequentially applies its inputs to an analogue-todigital converter 31 and an average response computer 33 which averages out background noise and applies its output to the data scan 60. A clock and cycle control 36 controls each of the data scan sequences and a time stamp 61 which stamps the time on the recording paper of a graphic recorder 23 whose single pen is controlled by the signals from data scan 60. In this manner a record may be produced as shown in Fig. 3. The clock and cycle control 36 also applies a calibration pulse over lines 50-52 to test the apparatus. In any of the integrated EKG, EEG, and averaged signals fall below a pre-set threshold an alarm 59 is activated. In an alternative, Fig. 2 (not shown), the analogue signals from data scan 21 are not digitized and an analogue average response computer is then utilised. Further, the data scan 60 is omitted and the graphic recorder has three channels to record simultaneously the EKG, EEG, and averaged signals, Fig. 4 (not shown). The embodiment of Fig. 1 may be provided with the graphic recorder of Fig. 2 and vice versa.

Abstract: 1,258,191. Air cushion vehicles. BRITISH HOVERCRAFT CORP. Ltd. 20 Jan., 1970 [21 Jan., 1969], No. 3299/69. Heading B7K. [Also in Division G3] Variations in pressure within a fluid pressure cushion 8 supporting a load bearing platform 1 are sensed by at least one pure fluid device 13 the output from which actuates pressure control means 31 in the fluid supply 11 to the cushion. The cushion is formed by a diaphragm 2 of natural rubber, neoprene or polyurethane secured at its centre 3 and periphery 4 to the platform. Convolutions concentric to the central fixing provide a number of concentric annular air spaces above the diaphragm when it is retracted. When a pressure fluctuation is sensed in the space above the diaphragm by a pitot tube 15 a pressure signal is transmitted through line 18 and lines 21, 22 to control nozzles 23, 24 of the pure fluid device. A capacity 25 causes a delay in the arrival of the signal at the nozzle 24 so that the flow from the power nozzle 28 is deflected against a bias pressure from a nozzle 27  into an outlet 32 to cause the means 31 to reduce the supply 11. The system may be used to suppress pressure oscillations in the cushion of a hover vehicle. A three-stage proportional amplifier may have its first stage connected to two pads of a four-pad hover pallet and its remaining stages each connected to one of the other two pads. In a further embodiment, the pure fluid device does not sense pressure changes within the cushion but is connected to a jet discharging on to a spring mass responsive to oscillation of the pallet. The system may also be used in conjunction with a vehicle having a supporting cushion divided into separate compartments or a number of separate support cushions.

Photo-electric apparatus is used for measuring the optical density or transmissivity of sample and reference stips of chromatographic thin layer media, for example glass plates coated with absorbent medium, filter papers or gelatine layers. In the arrangement shown, light from a carbon, Xenon or Xenon-Mercury lamp may be filtered by spectral filters or passed through a monochromator before being incident on a double slit system to form the two beams L shown. The intensities of the beams are controlled in unison by diaphragm 1. The cross-sections of the beam are defined into slits by aperture plate 3 and plate 2, before incidence on the thin layers. Two or more strips of layers are defined by scoring device 7, which is adjustable to give different strip widths, and the layer carrier is continuously moved through the light path. In between the scoring station and the light path, the substance under investigation is applied to a particular one of the strips, the other strip acting as a reference. Both strips are treated with developing reagents. Light passing through the strips can be filtered by a movable or adjustable interference filter wedge 10 before direction by mirrors 10 to separate photomultipliers 5, 6 for the reference and sample beams, the intensity ratio of which is determined.

In Fig. 1 storage elements 12 arranged in two blocks 10, 11 have ferromagnetic layers 14, dielectric protective layers 15, and coils 13 (one per element 12 through Fig. 1 shows only one per block). Light source 20 parabolic mirror 22, polarizer 23, analyser 24 and photo-cell 25 are provided for read-out. Information is stored as the directions of magnetization in layers 14 of block 11, and the elements of block 10 are magnetized appropriately to select the required elements of block 11 for read-out. The blocks may be potted in plastics material. A first modification joins the corresponding elements 12 of blocks 10 and 11, the layers 14, 15 of block 11 being at the other end. A second modification differs from this in having the layers 14, 15 on the longitudinal surface, entering the light obliquely, and obtaining parallel and serial read-out simultaneously using light reflected from the entry end and light transmitted down the length of the element with multiple internal reflection, respectively.

Abstract: 1289720 Emergency oxygen apparatus MINE SAFETY APPLIANCES CO 14 Oct 1969 [29 Oct 1968] 50462/69 Heading A5T [Also in Division F4] Emergency oxygen apparatus for use with a primary oxygen supply system 15, comprises a storage tank 1, 2 provided with an outlet, a pressure reducing valve 4 connected with said outlet and having an outlet for connection with the demand valve 5 of a breathing mask 6, and conduit 9 adapted to be connected with the primary system 15 for delivery of oxygen under pressure therefrom to the tank, a check valve 12 in the conduit permitting flow only toward the tank, at least one oxygen producing candle (17), Figure 1 (not shown), the or each candle contained in a receptacle 18, a conduit 19 connecting each receptacle 18 with said tank 1, 2, and manually operable means for igniting the candle or candles (17) to produce oxygen. The apparatus is connected to the primary system by means of a quick-release coupling 10. The tank 1, 2 comprises five cylinders disposed side by side and connected in parallel. The means for igniting the candle or candles (17) comprises a circuit 26 which is operated by pulling a lanyard 30. However, the circuit is only complete if a pressure switch 39 is closed, the pressure switch being responsive to the pressure in the tank 1, 2, closing when the pressure is below a predetermined value. A secondary emergency oxygen source comprises two candles in receptacles 41 connected to the tank 1, 2 by tubes 42. The secondary candles are ignited by means of a circuit 47 which is operated by pulling a lanyard 51. The same lanyard 51 also operates a third circuit 55, which circuit is connected via the pressure switch 39 to batteries 32 of the circuit 26 for ignition of the candles (17) without pulling the lanyard 30. The arrangement is such that, if the lanyard 51 is pulled, the secondary candles are ignited to supply oxygen to the tank 1, 2, this causes the pressure switch 39 to open and thus prevent the candles (17) from igniting. After consumption of the secondary candles, the pressure in the tank drops closing the switch 39, and the candles (17) ignite. The candles are of sodium chlorate and the oxygen given off passes through filters (20, 21) in the candles and tank, respectively, before entering the pressure reducing valve 4. The candle receptacles 18, 41 are enclosed in protective heat-insulating jackets (65).
