Patent GB-1148661-A (GB)
Title: Improvements relating to chromatography
Inventor: PRETORIUS VICTOR
IPC: G01N30/52
Filed: 1966-05-09
Abstract: 1,148,661. Chromatographic separation. V. PRETORIOUS and H. H. HAHN. 9 May, 1966 [11 May, 1965], No. 20366/66. Headings BIL and B1X. To hasten separation in chromatography separating processes taking place in a tubular passage and involving the use of a retarding phase and a material forwarding phase, where the material to be separated is phase interchange between the phases, the forwarding phase is maintained in turbulent flow and the contribution to the efficiency of the column by the retarding phase is maintained low by employing a retarding phase in which the material exchange is confined to the immediate vicinity of the surface. The retarding phase may be a solid non-porous absorbent, e.g. metal and glass, or porous substances devoid of blind pores, e.g. activated charcoal, alumina, silica gel, molecular sieves and organic polymers, or thin liquid films on solid particles or on supports, or thin layers of ion exchangers. The turbulent flow may be assisted by providing obstructions within the column or by vibrating the column. In the apparatus of Fig. 3 the retarding phase consists of particulate material maintained in an expanded state in a column 11 by the upward turbulent flow of a forwarding phase entering through inlet 12. One desired fraction leaves the column together with the forwarding phase at 23 while the other desired fraction is withdrawn with the retarding phase at 15 and is stripped off the retarding phase in column 17 by the upward flow of a stripping medium. The retarding phase tends to settle at the top of column 17 and from there returns by gravity via standpipe 21 to column 11. In Fig. 4, the column is divided transversely by screens permeable to the forwarding phase into sections of height equal to the column diameter such that the particulate material in each section is in turbulent condition but is maintained within that section.

Title: Respiratory biofeedback training and performance evauation system
IPC: A61B5/00
Filed: 1976-05-18
Abstract: 1530215 Respiration training D HILLSMAN 18 May 1976 [19 May 1975] 20440/76 Heading G1N(E) [Also in Division G5] In a respiration bio-feedback training system, Fig. 5, a parameter of the patient's respiratory airflow is monitored and displayed in waveform together with an ideal waveform so that the patient may look at the display and control his or her breathing to emulate the waveform. The patient breathes into a flowmeter 1 containing a transducer 2 whose electrical output is amplified 3 and supplied to an integrator 5 to provide a volume signal. The integrator 5's output is supplied via an A/D converter 14 and a data multi-plexer 17 to a random access memory (RAM) 18. The parameters associated with the "ideal" waveform are stored in read only memories (ROM) 32, 33, 34, whose store values are controlled by three selection switches 8, 9. An oscillator 7 provides timing signals that are used by column counters 11, address multi-plexer 16 and line counter 28 to control the T.V. display and. the addressing of the RAM 18 and the ROMS 32, 33, 34. The RAM and the ROM are thus alternately sampled and supplied via buffer amplifiers 21, 29 to a comparator 26. In the comparator the values are compared with the current cathode ray tube scanning beam position to either generate a video display signal or not. The ideal waveform will be displayed as a broken line and the patient's waveform as a solid line. The digital values of the RAM and the ROM may also be converted into analogue values by D/A converters 38, 22 and supplied to two comparators 24, 44 designed to actuate buzzers 25 depending on two different levels of error between the ideal waveform and the patient's waveform. A one shot multi-vibrator 6 provides a "start of inspiration pulse" which resets the integrator 5, the data counter 12, enables the random access memory 18 through the "OR" gate 19 and causes the multi-plexer 17 to feed blanks as data into the RAM. The description also discloses modifications Fig. 1a (not shown) including manual switches to signal the onset of respiration (instead of the comparator 4) or to "freeze" the ideal waveform. In another modification Fig. lb (not shown), a blinking dot display can be obtained by modifying the circuitry of Fig. 1. The blink position is kept just leading the real time data. Fig. 4j (not shown). A circuit Fig. 2 (not shown) for connecting digital data to a T.V. set is disclosed. The description states that other dynamic electro-optic display devices may be used. A set of waveforms illustrating the various and various patient performances are disclosed.

Title: Coin-freed meter for electric current, gas, water or the like
IPC: G07F15/06
Filed: 1920-07-12
Abstract: 151,973. Allgemeine Elektricitõts- Ges. July 4, 1917, [Convention date]. No Patent granted (Sealing fee not paid). Electricity, gas, and liquids, supplying by meter.-Relates to electricity and other meters of the kind in which a fee for rent or the like must be inserted before the apparatus can be used as an ordinary coin-freed meter. According to the invention, the cash drawer of the meter contains means for locking the usual prepayment mechanism until the rent fee has been inserted into additional coin-receiving mechanism in the drawer. The coin-disk b is normally locked by a pawl e, pivoted on the framework of the meter and connected by a spring j to an arm h mounted on the same pivot and controlled by a spring g. Within the cash-drawer c is a spring-controlled slide n, carrying a pivoted rod p, and also having an external coin-slot. The slide normally abuts against the arm h. On inserting a coin and pushing in the slide, the coin falls between a fixed plate and a pivoted plate s, which is normally held by a spring in engagement with a projection on the slide. The coin forces the plate s aside, so that the slide can then, on release by the operator, move outwards under the action of the springs o, g. By this means the arm h is freed and is rocked by the spring g so as to disengage the locking-pawl e from the disk b. Coin-discharging mechanism.-As the slide n moves to its outer position (in which it becomes locked by a tooth g on the rod p) a cam slot in the slide, by engagement with a projection from the plate s, moves the plate sufficiently far to allow the coin to drop into the drawer.

Filed: 1918-12-18
Abstract: 139,841. George, J. W. Dec. 18, 1918. Fixed-abutment type; Cooling parts.-A rotary internal - combustion turbine comprises a rotor 9 fixed to a hollow shaft 8 and provided with radial inlet passages 10 communicating between the hollow portion 11 of the shaft and the opposite surfaces 12 of the rotor. The rotor is also provided with radial scavenging-air inlets 18, the openings 20 of which are opposed to the fuel outlets 13. Axial slots 21 adjacent to each pair of outlets 13, 20 carry vanes 22, Fig. 2, adapted to slide between casings 23 formed with induction and compression chambers 29 and abutments 30, Fig. 4, so that the axially sliding vanes continuously contact with the opposed surfaces of the casing. The outer ends of the combustion chambers 34 open on to turbine wheels 36, 37 at each side of the rotor and outside the casing. The turbine wheels are separated by stationary rings 38. The blades of the wheels are preferably arranged with blank spaces between each series to travel past each outlet during compression. In operation, the vanes 22 induce a charge in the spaces 29 from the shaft 8, which is compressed by the next following vane into the combustion chamber 34. It is then fired and acts on the turbine blades. During the induction of the charge, each alternate vane induces a charge of air into the chamber 29, which is similarly compressed and expelled through the turbines. Cooling is effected by chambers 32 and by the spaces 17 being open to the air. In modifications, compression and combustion chambers and one turbine wheel may be provided at one end only of the engine, and the vanes may be pressed into their operative positions by positive means. The turbine wheels may be rotated at different speeds or in the opposite direction to the rotor or to each other. The turbine wheels may have an uninterrupted series of blades, slotted rings replacing the blank spaces. The scavenging-air may be forced straight through the blades without compression. Specification 120,787 is referred to.

Abstract: 964,187. Bottling. W. PECHMANN. June 1, 1962 [June 8, 1961], No. 21225/62. Heading B8T. Each filling head of an ampoule filler comprises a filling tube 27 displaceable vertically to be insertable into the ampoule neck 10a, surrounded by a tubular casing 29, the tube and casing being longitudinally displaceable relative to one another so that when the tube 27 is removed from the ampoule its outlet 32 is disposed within its casing, thus preventing the wetting of the inner wall of the ampoule neck. The ampoules 10 are conveyed by an endless conveyer 11 past a series of successive treating stations 12 where they are washed, dried, sterilized &c., and on reaching station 13 are filled, and are sealed at station 14. The ampoules are suspended by their necks in the conveyer, which is in the form of a wire mesh, and each filling tube depends from a holder 28 in a vertically reciprocable beam 16; its tubular casing depends from a sleeve 31. When the beam is lowered to lower the filling tube into the ampoule, the sleeve strikes an abutment 33 whereby the end 35 of the tube extends from its casing ready for the filling operation, the liquid being supplied through the holder 28. A suction is created between the tube and casing via a bore 37 in the beam when the tube outlet is withdrawn into its casing, Fig. 2, thereby to withdraw any liquid from the end of the tube. On striking the abutment the sleeve is lifted to break the suction. A gauging mandrel 21 is located at the first station, Fig. 1, to force from the conveyer those ampoules having necks that are too narrow to receive the tubular casings of the fillers.
