Title: Improvements in or in connection with apparatus for cleaning the screw stoppers of bottles, and for washing potatoes, carrots and the like, and articles which are not of a fragile nature
IPC: B67B1/03
Filed: 1921-12-05
Abstract: 193,185. Hill, T. Dec. 5, 1921. Stoppers, cleaning.-In rotary drum machines for washing the screw stoppers of bottles, also adapted to wash potatoes &c. the ends of the partly-immersed drum are not perforated and the periphery of the drum is formed of spaced bars of channel section adapted to carry up liquid and spray the contents of the drum so that a continual flow is caused which carries out of the drum the labels and the like which are washed off, these being then caught in a fixed trough. The drum is formed of two solid flanged discs G, G' connected by bars g<1> of channel shape, some of the bars being removable for the introduction of the stoppers &c. The shaft C of the drum rests in grooves E<1> in the top of a tank A and is rotatable in a frame D pivoted to a crossbar F fixed to the tank. Handles d and counterweights d<1> on the frame enable the drum to be swung from one part a<2> of the tank into another part a<1> these parts being separated by a partition B. Washing liquid is contained in the part a<2> and a removable tray K in the part a<1> for the reception of the cleaned articles. The drum may be rotated by hand or driven through a pulley L running freely on the bar F and driving a sprocket wheel L<2> which is connected by a chain M with a sprocket wheel c on the shaft C. As the drum rotates the washings are caught in a perforated trough J which acts as a filter to retain the labels &c.

Abstract: 458,290. Valves for burners. PARKES, S. C., 67, Meadow Walk, Ewell, Surrey. Nov. 25, 1935, No. 32654. [Class 135] A device for preventing waste of gas in a burner 14 on removal of the vessel which is being heated, comprises a gas nipple 27, replacing the usual jet, and a readily removable air mixing tube 13 carrying a lever 11 pivoted at 12. The lever 11 carries adjustably a " treadle " 19, which is depressed by the vessel on the hot plate 20 thus raising an adjustable abutment 25 on the end 24 of the lever, which abutment is of sufficient area to engage and open the sliding plug valve 30 against the action of a spring 32. The spring 32 lies in a slot in the end of the plug, also preventing its rotation. A spring 23, formed also to prevent lateral movement of the lever 11, returns the lever on removal of the vessel. The plug valve permits passage of a small amount of gas when the vessel is removed. Specification 7018/87, [Class 135], is referred to.

Title: Improvements in electrolytic apparatus
IPC: C25B9/19
Filed: 1919-12-31
Abstract: 155,457. Levin, I. H. Dec. 31, 1919. Cells; diaphragms; electrodes; electrolytes, circulating; oxygen and hydrogen, obtaining.-Apparatus wherein one electrode is formed by the cell and another is supported by, but insulated from, a cover is provided with an inverted troughshaped partition pendent from the cover and separating gas chambers above the electrolyte, which can flow from one side of the partition to the other through a hole near but below the surface of the liquid. The partition may support a diaphragm. Two or more such partitions f, Figs. 2 and 3, may be arranged so as to form separate chambers for one gas within a single chamber for the other gas. Partitions c rising from the cell floor are then provided to act as additional electrodes between the suspended electrodes d and diaphragms e, and may have apertures near the floor for liquid flow. Along one side of each of the inner gas chambers the partition f carries a trough g having open compartments on each side of the partitions. At one end of each trough compartment is an opening for electrolyte, while their other ends communicate by holes below the liquid level with a chamber f<4>, closed to both gas chambers and connected by a duct i with a supply cup h. Electrolyte passing from one compartment of the cell to the other is freed from gas while passing along the trough compartments. Ducts l lead from the inner gas chambers to an outlet k and gas washer k<1>; the two gas washers are connected to a liquid reservoir m. Each suspended electrode consists of a flattened sheet-metal cup d, perforated for circulation of liquid. It is suspended-by cross-pieces d<1> and stems d<2> from nuts d<3> which are clamped by insulated screws against insulating washers on the cover. Diaphragms e similar in form to the electrodes d are secured to the partitions f and troughs g. The cover b is provided with'a flange resting on insulating pieces at the bottom of a trough a<1> which contains oil, distilled water, or other non-conducting liquid. In modifications, the cover is clamped against compressible material, the liquid seal being dispensed with; the partition, instead of being integral with the cover, is formed by an inverted trough fitted in a hole in the cover, or carried bv the electrode stems below the cover; and each trough g may extend all round the inner gas chamber, being connected by studs. to the partition. Distilled water may be used for replenishing the alkaline electrolyte. Reference has been directed by the Comptroller to Specifications 12765/98, 21557/00, and 2124/12.

Abstract: 1,246,746. Electro-chemical analysis cells. INTERNATIONAL BUSINESS MACHINES CORP. July 1, 1969 [July 15, 1968], No.33042/69. Heading G1N. In apparatus for coulometric determination of glucose in blood or urine, glucose diffuses from the sample 2 through a semi-permeable membrane 3 into an electrolyte 4 in which it is oxidized by glucose oxidase to form gluconic acid and hydrogen peroxide and the hydrogen peroxide is then decomposed by iodide ions which are regenerated by a galvanic coulometric system comprising a calomel electrode 12 and a platinum mesh electrode 13. When equilibrium is reached, the current through meter 16 is proportional to the diffusion rate of glucose through the membrane 3 which is in turn proportional to the concentration of glucose in the sample 2. The electrolyte 4 may consists of a mixture of KC1, KI, KH2PO4, K2HPO4, (NH4)2 MO4 (as a catalyst for decomposing peroxide) and the enzyme glucose oxidase.

Title: Improvements relating to x-ray apparatus
IPC: H05G1/42
Filed: 1966-07-22
Abstract: 1,119,394. Electric selective signalling. PICKER X-RAY CORP. WAITE MFG. DIVISION Inc. 22 July. 1966 [28 July, 1965], No. 33115/66. Heading G4H. [Also in Division H3] Exposure of a film to X-rays is terminated when a count, of pulses obtained by integratng and digitizing the electrical output of an X-ray sensor, reaches a predetermined value. While a patient is being X-rayed, the exposure of the film is measured by detecting light from a fluorescent screen behind the film by means of a phototube. The phototube output current is integrated and digitized to a train of pulses which are counted. When the count reaches a preselected value set up on a switch, the power supply to the X-ray generating tube is automatically shut-off. The X-ray tube current is also integrated and digitized and the pulses may be fed to the counter in place of those derived from the phototube output, the power supply to the X-ray tube being shut-off when a preselected count set up on a second switch is reached. Integrating and digitizing phototube output current (Fig. 2).-When current from the phototube at 50 has raised the gate of a field effect device 103 to about - 1 volt, it begins to conduct, making transistor 106 conduct, whereupon capacitor 116 discharges to make transistor 112 conduct to move the base of transistor 120 positively. This increases the potential on the gate of field effect device 103 via transistor 120 and capacitor 130 to make device 103 and transistors 106, 112 conduct more strongly. Clamping diode 133 prevents the gate of device 103 rising above ground and Zener diode 117 prevents the base of transistor 120 rising above +10 volts. When capacitor 116 has discharged, transistor 112 cuts off, line 131 drops to about ground and line 132 drops to - 10 volts. One pulse has thus been produced in an output line 54, and the cycle can repeat. The number of output pulses at 54 will equal the time-integral of the phototube current at 50.
