Abstract: 1,157,839. Proofing press; registration and make-ready apparatus. WALBERT EQUIPMENT CO. 4 Aug., 1967, No. 36013/67. Heading B6C. [Also in Division G2] A proofing press for establishing registration and simultaneous surface adjustment of printing plates comprises an optical system for comparing images of a master and the plates. Fig. 1 is a sectional view through the press in which the master 25 is mounted on a draw-sheet 21 which is aligned on a cylinder 12 provided with pins 20 corresponding to similar pins carried on the printing cylinder of the main press; a negative printing plate 27 is similarly mounted on a draw-sheet 22 of a second cylinder 13, adhesive strips 24 being used to return the draw-sheets on the cylinders, and strips 26 to retain the master on the draw-sheet. An eye 50 of an observer views the image of the master reflected in mirror 29 and transmitted through semi-transparent mirror 30 (paths 51, 52, 55) and views the image of plate 27 reflected in mirrors 31 and 30 (paths 53, 54, 55); the plate 27 is moved on the draw-sheet 22 until the images coincide. A proof can be run by inking plate 27 through fountain 74 and rollers 73, 76, and then bringing proof cylinder 14 with attached sheet 78 into rotative contact. The printing pressure is adjusted to correspond with the main press pressure by means of hand crank 68 with calibrated dial 67 which rotates threaded shaft 63 in a bore 61, the bore being part of a slide assembly in which cylinder 14 is journalled. Inspection of the proof sheet provides indication of those areas where inserts are required under the draw-sheet. During this " make-ready ", the plate can be registered whenever required by the optical system described above.

Title: Method and apparatus for the detection of a contaminant in air or other gases
IPC: G01N21/77
Filed: 1963-09-16
Abstract: 1,017,545. Gas analysis. C. O. HARVEY. Sept. 23, 1964 [Sept. 16, 1963], No. 36434/63. Heading G1B. In a method of detecting a contaminant in a gas, the gas is passed through a mass of solid particles at such a rate as to impart turbulence to the particles, the particles comprising a reagent which undergoes a colour change after reacting with the contaminant. A suitable apparatus comprises an electric motor 1 driving an air blower 2, a flow meter 3, an absorbing unit 4 and an intake filter 5 for the blower. The absorbing unit consists of two stainless steel gauze discs sealed into the ends of a conical vessel 7. A powdered solid 8 impregnated with the reagent is poured into the unit 4 through a side arm 9 which is then stoppered. Air or gas is blown up through the unit 4, the powdered solid rising centrally and falling back at the walls of the vessel 7. When a suitable volume of air or gas has been passed through the vessel 4, the powdered solid is removed and its colour assessed by comparison with a series of standards. The method is useful in detecting contaminants present in only low concentrations e.g. below 1 part per million. Suitable reagents are silica gel treated with zinc nitroprusside for SO 2 , silver fluoride for AsH 3  PH 3  or SbH 3 , and cuprous iodide absorbed on silical gel for mercury vapour.

Abstract: 860,505. Electrical transformers. MULLARD Ltd. Nov. 16, 1959 [Nov. 14, 1958], No. 36721/58. Class 38 (2). A magnetic pot core for a transformer or inductor is in two parts 10, 19 inside a brass container 1, which parts are urged together between a spring washer 22 and an insulating base 6 held against the rim 2 of container 1. The force applied by the washer to the core parts so that a required value of inductance is obtained, is varied by screwing member 27 in retaining-plate 24, if desired until flange 28 abuts plate 24. This plate is held in container 1 by bayonet joint co-operation of cut-outs in its edge with slots 4 in ribs 3 of the container. It is located by lugs 32 bent inwardly to engage one of the cut-outs. The transformer may have flying leads or terminals 8 on plate 6, and may be mounted on a panel by nut 31.

Abstract: 343,619. Siphon bottles &c. DEANESLY, H., The Willows, Bushy Park Road, Terenure, Dublin, and GUINNESS SON & CO., Ltd., A., Salisbury House, Finsbury Circus, London. Nov. 30, 1929, No. 36763. [Class 14 (i).] A receptacle for liquid under pressure comprises a body 1, a gas container 7, and a head 4 containing valves for the control of the liquid and gas, which screws airtight upon the neck 2 of the body. The vessel 7 is charged with gas by means of a screwed nipple 17 and a non-return valve 16. A diaphragm 19 in the head carries a valve 26 and a projecting pivot 28. At one side a screwed stop 31 is provided for closing the valve 26 on a seat 30, and at the other a spring 34. The space beneath the diaphragm communicates with the vessel 1 through a valve 14b. The pivot 28 is nearer to the valve 26 than to the spring, so that the gas pressure in the vessel 1 acts on the diaphragm to close the valve 26. The upper side of the diaphragm is open to the atmosphere. Liquid is discharged from the vessel 1 by way of a pipe 9 having a venturi nozzle 10 and a screw-down valve 13.

Title: Centrifugal Pumps.
Inventor: SCOTT-SCOTT JOHN LANFEAR
IPC: F04D15/00
Filed: 1967-08-11
Abstract: 1,195,993. Centrifugal pumps. ROLLSROYCE Ltd. Aug.8, 1968 [Aug. 11, 1967], No.36981/67. Heading F1C. A centrifugal pump comprises an impeller and a rotor body mounted coaxially and upstream of the impeller and rotatable with the impeller, the pump being intended to be operated with a low flow inlet angle and at a low suction pressure, the rotor body having a number of circumferentially - spaced, rod-like, bluff projections extending therefrom transversely across the inlet passage of the pump. A centrifugal pump for liquid or a mixture of liquid and gas and operating at a low flow inlet angle, e.g. less than 3 degrees or 4 degrees, and at a low suction pressure e.g. about 1 or 2 pounds per square inch above the vapour pressure of the liquid, comprises pins 14 for preventing the formation under these conditions of vapour-filled regions in the eye 15 of the impeller 1 and consequent instability and decrease in flow. The pins 14 each produce a trailing cavity containing vapour or gas, the cavities being of helical form and merging together downstream of the plane of the pins to form an annular cavity extending downstream into at least the impeller eye 15. The annular cavity enables the pump to be operated stably and forms a region of fluid of lower viscosity than the liquid being pumped tending to prevent transmission of pre-whirl to the liquid upstream of the region. The reduction of pre-whirl assists in preventing instability. The length of the pins 14 is at least 30% of the distance across the flow passage and is preferably between one and six times the diameter of the pins. Instead of extending radially as shown, the pins may be inclined in either or both the axial and circumferential directions. The length and inclination of the pins may be adjustable. The cap 9 carrying the pins may have an annular lip of resilently deformable material which is snapped over an undercut annular rib on the impeller or impeller shaft. The flow through the pump may be varied by means of an iris diaphragm provided in the inlet passage 5. Otherwise, liquid may be returned from the volute 6 through a control valve 22 to a manifold 25 having an annular opening 26 extending around the inlet passage 5. Liquid discharged from the opening 26 forms a boundary layer having a low or reverse velocity and reducing the effective flow area in the inlet passage 5. Instead of an annular opening 26, nozzles facing in an upstream direction may be provided.

A chain stopper for a ship's anchor chain A comprises a tongue 1 which is carried by an eccentric shaft 2. A hand wheel 10 is in threaded engagement with the shaft 2 and may be connected for rotation with the shaft 2 by means of the engagement of conical-shaped clutch elements 17, 18, on the pulling outwards of a knob 16. The tongue 1 may then be rotated out of engagement with the chain A by rotation of the hand wheel 10. If the knob 16 is pushed in, the hand wheel 10 may be rotated on the thread 12 of the shaft 2 until it abuts a shoulder 20. A brake ring 22 carried by a disc 21 rigid with the shaft 2, is thereby drawn into engagement with a fixed disc 23.
