Title: A method of, and means for, automatically forming artillery correction values
IPC: F41G3/00
Filed: 1939-06-28
Abstract: 530,607. Ordnance sights and methods of sighting. CONTRAVES AKT.-GES. June 28, 1939, No. 18854. Convention date, Feb. 14. [Class 92 (ii)] Apparatus at the gun for correcting the angles of elevation and training and the fuze times wheh passing from one target to another, or from a burst near the target to the target itself, comprises an instrument 4 which receives the angle differences as to azimuth and angle of sight from two observing stations and converts them into changes #x, #y, #z of the co-ordinates x, y, z at the gun representing range, bearing and height or target respectively. Further instruments then convert these increments automatically into corrections of elevation ##, training # # and fuze-times ## for use at the gun. Cams 5, 6, adjusted in known manner axially in accordance with range x and rotationally in accordance with height z, give the elevation correction values per unit of deviation which are multiplied by #x and #z respectively in calculators 7, 8 the outputs of which are added in calculator 9 to give the elevation correction. The training correction is given by a calculator 10 which divides #y by x. Further cams 11, 12, adjusted similarly to the cams 5, 6, give the fuze-time correction per unit of deviation of range #x and height #z. Multiplication by #x and #z is effected in calculators 13, 14 and addition of these results by the calculator 15 gives the fuze-time change ##. The adjustment device 16 enables the fuze-time to be corrected to give a burst, say, 10 metres above the target. Further cams, cut in accordance with the sine and cosine of the angle of incidence of the trajectory, may be used to correct the fuze-times for a burst, say, 50 metres in front of the target. Specification 520,228, [Group XIX], is referred to.

Title: Improvements in or relating to the intensitication of photographic images
Filed: 1943-11-13
Abstract: 570,703. Intensifying photographic images. KODAK, Ltd. (Eastman Kodak Co., and Simmons, N. L.). Nov. 13, 1943, No. 18925. [Class 98 (ii)] Latent images in silver-salt emulsion layers are intensified by treatment with sulphur dioxide gas. The effective speed of the emulsion is thereby increased. The gas may be produced externally by adding developer containing sulphite ions to dilute acetic acid, or by the action of sulphuric acid on an aqueous solution of sodium sulphite, or from liquid sulphur dioxide maintained at a temperature below its boiling- point. The exposed sensitive material and the source of sulphur dioxide may be allowed to stand for the required period in an open tray or in a closed vessel: long films may be passed through a cabinet containing the gas. Alternatively, the material may be saturated with the gas by contact with it for a short period, and then be transferred to a closed container for a longer period during which the intensification proceeds. Examples are given illustrating the effect of treating ordinary and colour-sensitive films for periods varying from 5 minutes to 48 hours. Reference is made to other methods of latent-image intensification by treatment with ammonia gas, by exposure to a safe-light, or by the action of heat and humidity as described in Specification 510,808.

The tool is mounted on a base 10 slidable on a fixed bed 12 located above a disposal vault for active waste the entry port 13 of which is closed by a shield plug 14. The tool frame 15 carries a front guide tube 17, a seal plug retraction cylinder 18 and a two-part articulated clasp sleeve assembly 19. The clasp assembly comprises an upper non-pivoting sleeve 21 and a lower pivoting sleeve 24 each provided with clamping jaws 31 actuated hydraulically or pneumatically by rams 32 and 33 respectively. A tie rod to be broken passes through the aligned sleeves and clamps and rests on a retractible rod stop 50 positioned over the entry port 13. The lower sleeve is oscillated by a hydraulic or pneumatic cylinder 42 mounted on a lead screw 45. In the event of failure of the cylinder 42 the sleeve may be brought to a vertical position manually or by a motor through a transmission 47. A leadscrew mechanism 60 is provided for moving the tool along the bed 12 and a manual transmission 64 is provided for emergency use. In operation, the retraction cylinder 18 is energized to withdraw the shield plug 14 into a guide sleeve 75. The tool is moved horizontally by the leadscrew 60 until the clasp sleeve assembly 19 is located above the entry port 13. With the clamps open a tie rod is lowered by a hoist (not shown) until its end rests on the stop 50. The clamps are closed and the cylinder 42 actuated to oscillate the lower clasp sleeve. On breakage of the tie rod the oscillation is stopped, the stop 50 is retracted and the lower clamp 30 opened to allow the parted lower part of the tie rod to fall into the vault. The stop 50 is advanced to cover the entry port and the upper clamp 30 is opened to allow the remainder of the tie rod to be lowered on to the stop in readiness for a further cycle of operations. The tie rod may be released from the lower clamp by a latch 80 in the event of seizure of the lower clamp cylinder 33. The front guide tube 17 is used as a bypass for a fuel tie rod on failure of the breaking tool or in an emergency. The tool is provided with limit switches connected to an indicator circuit which indicates the positions and operation of the various parts of the tool.

Title: Improvement in sectional boilers for central heating systems
IPC: F24H1/38
Filed: 1969-04-15
Abstract: 1,262,932. Sectional boilers. D. FERROLI [trading as FERROLI-GAS S.n.c.]. 15 April, 1969, No. 19148/69. Heading F4A. In a sectional boiler, e.g. for gas-fired central heating, in which each section is a flattened hollow body the larger faces of which form, with the larger faces of adjacent sections, flue gas passages, these faces are of undulated horizontal cross-section, and horizontal fins are disposed at alternated levels on the two larger faces of each section so that each passage is correspondingly undulated in vertical cross-section. Each section comprises a water passage 13, Fig. 6, extending between an inlet sleeve 10, Figs. 5 and 6, and an outlet sleeve 12, the inlet sleeve being integral with a hollow extension 11 which, together with an opposed shorter extension 14, encloses a combustion space 15. The transversely extending faces 19, 20, Fig. 4, of the sections are corrugated in horizontal cross-section and have horizontal fins 22, 23 disposed at alternated levels to cause the flue gases ascending through the space 21 between each pair of adjacent sections to take the tortuous path shown in Fig. 6, whereby heat exchange is promoted. The faces 19, 20 of each element diverge from one another from bottom to top to provide a corresponding decrease from bottom to top of the cross-sectional area of the space 21 to compensate for the contraction of the flue gases due to loss of heat.

Title: Improvements in and relating to apparatus for the electrical storage of digital information

IPC: G11C11/23
Filed: 1951-08-15
Abstract: 719,078. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 1, 1952 [Aug. 15, 1951], No. 19286/51. Addition to 657,591. Class 106 (1). [Also in Group XL(c)] In a cathode-ray tube store of the type described in the parent Specification and in which a defocused beam is employed to set up one state of charge and a defocused beam, subsequently focused, is used to set up an alternative state of charge, the defocused beam is moved a short distance beyond the edge of the defocused beam position. This arrangement is stated to overcome false reading when an item of information is changed from the defocused only to the defocused-focused condition. A master pulse generator 20 controls through a divider' 21, X- scan and Y-scan generators 22, 23, and also directly dot and dash generators 24, 26. The waveform, Fig. 2 (a), from the dot-generator switches on the cathode ray tube beam to cause a waveform, Fig. 2 (f), to appear in the output of amplifier 27 from an " 0 ". A pulse, Fig. 2 (h), from strobe generator 28 causes a slightly negative voltage to occur whereas with a " 1 " resulting from a defocused-focus operation, a positive voltage occurs as a result of a selection from the waveform, Fig. 2 (g). When a " 1 " is converted to a " 0 ", the first regeneration may result in a waveform 36 in the amplifier output which could be read as a positive voltage during the strobe period indicative of a " 1 ". This fault is overcome by the use of a Y-shift voltage, Fig. 2 (d), which causes the beam to be displaced during focusing, Fig. 2 (e), the beam being switched on again for a " 1 ", Fig. 2 (b), during the focusing operation. The beam is held stationary throughout the period when focusing may occur, Fig. 2 (c). Specifications 705,474 and 705,482 also are referred to.
