Title: Improvements in or relating to scoring and marking apparatus
IPC: A63B71/06
Filed: 1929-09-26
Abstract: 336,391. Norman Sports, Ltd., and Fraser, P. S. Sept. 26, 1929. Scoring and marking apparatus.-A scoring apparatus, particularly for indicating cricket scores at a distance, comprises three rotary drum indicators displaying the scores through openings in a board, means including a control handle or wheel for driving each indicator, and free-wheel devices between two of the indicators and the third indicator so that the third indicator is operated simultaneously with the two indicators but can be operated independently thereof. As shown, the score board has three numeral drums for the total score A', two numeral drums for each individual score A<2>, A<3> and additional indicators for last player, bowlers, &c. The operating mechanism for the numeral drums comprises two coaxial shafts G<2>, G<3> situated above the scorers head and rotated by handles G, G'. At each complete rotation of a handle, cams on the corresponding shaft impart a rotary movement to numbered unit wheels on a shaft F and this movement is transmitted by chains D, D<3>, D<5> to the unit drums of the total indicator A<1> and of the corresponding individual indicator A<2> or A'. The cams for operating the total indicator are carried by the adjacent ends of the shafts G<2>, G<3> so as to actuate the same number wheel J but are normally out of operative connection therewith so that each shaft may act independently on the total indicator. In order to operate the total indicator independently of the individual indicators a number wheel P is attached to the units wheel J and is provided with a milled rim so that it may easily be turned by hand. A suitable transfer mechanism is provided on the shafts F. G<2>, G<3> for transferring the complete rotations of the unit wheels to the tens and hundreds wheels and this movement is transferred to the total and individual indicators by additional chains. The hundreds digits for the individual indicators may be put up by hand or an additional drum may be provided. To facilitate the zeroizing of the drums, the shafts G<2>, G<3> are mounted in a bracket which may be swung away from the shaft F. Additional indicating drums for " extras," operated bv the hand-wheel P, may be provided. In a modification where an operating handle and chain drive are connected directly to each of the three indicators and the carry-over mechanism is directly associated therewith, the individual indicators are mounted on a common shaft, and the total indicator is connected thereto by an arrangement of free wheels and gearing.

Title: Improvements in or relating to rust inhibiting compositions
IPC: C10L1/188
Filed: 1950-11-29
Abstract: Rust-inhibiting compositions consist essentially of a liquid hydrocarbon containing dissolved therein 0.025 to 5 per cent of polymerized linoleic acid.  They may be used as lubricating oils or motor fuels.  Other suitable bases to which the polymerized linoleic acid may be added comprise polishes, hydrocarbon polymers, paints, and sprays.  Other additives such as detergents, pour depressants, thickeners, extreme pressure agents, other rust inhibitors such as degras, petrolum sulphonates, pentaerythritol mono-oleate, lauryl mercapto acetic acid and sorbitan oleate, and other materials such as cut-back asphalts, microcrystalline waxes, and synthetic waxes may be included in the compositions.  When using mineral lubricating oils as the base, 1 to 2 per cent by weight of the polymerized acid is preferred.  The examples describe tests of compositions comprising 1 and 2 per cent by weight of polymerized linoleic acid in a naphthenic lubricating oil of 40 S.U.S. at 210 DEG F, and of a composition comprising a solvent-extracted lubricating oil fraction of 150 S.U.S. at 100 DEG F containing 0.1 per cent by weight of polymerized linoleic acid.

IPC: H05G1/62
Filed: 1969-06-10
Abstract: 1277232 X-ray apparatus X-SCOPE CORP 10 June 1969 [10 June 1968] 29257/69 Heading G1A [Also in Division H5] In a cardiac X-ray synchronizer - i.e. an arrangement for energizing an X-ray machine to produce on X-ray picture of a patients heart at a chosen point of the cardiac cycle, by using the R-wave peak of the cycle to energize the X-ray tube after an adjustable time delay - the time lapse between the application of the energizing signal to the tube and the production of the X-ray burst is allowed for by means of an electrical pulse which is initiated by a tube energizing signal, and the width of which is adjustable to permit calibration of the synchronizer. To calibrate for use with a given X-ray tube, these pulses, together with signals representing successive R-wave peaks e.g. from an R-wave simulator, and the signals from an X-ray detector mounted to receive the X-ray bursts, are applied to a cathode ray osacilloscope, and the pulse width adjusted until its trailing edge coincides with the commencement of the X-ray burst signal. As shown, the R-wave simulator 74 and X-ray detector 72 are connected via amplifiers 32 and 46 to cathode ray tube 64, the R-wave peak further octuating the detector 54, the output signal from which is delayed to an adjustable extent by the 'Event Selector Position' 56 before being applied both to the 'Driver' 58, which thereupon energizes the X-ray tube of the manual control unit 62 has been operated, and to the pulse operator 66, the output from which is applied to the cathode ray tube 64. Pulse generator 66 is adjusted to the condition shown in Fig.3, in which it terminates at the commencement of the X-ray burst. In use of the calibrated apparatus thereafter, switch 36 is moved to the position shown in Fig. 2 such that the cardiac signals from the patient electrodes 26, 28, 30 are applied to amplifier 32, and the 'Event Selector Position' 56 is adjusted, by reference to the cathode ray tube screen, until the trailing edge of the pulse from generator 66 is located at that point of the cardiac cycle at which the X-ray picture is desired, whereafter the 'Driver' 58 will, when the manual control 62 has been operated, trigger the X-ray tube at the appropriate point in the next cycle. The incorporation of a pulmonary synchronization unit, for further ensuring that triggering of the X-ray tube only occurs at a desired level of inspiration, is referred to.

Title: Charge coupled memory devices
IPC: H01L29/51
Filed: 1971-06-24
Abstract: 1356629 Semi-conductor device WESTERN ELECTRIC CO Inc 24 June 1971 [24 June 1970] 29656/71 Heading H1K A charge coupled memory device includes means by which the accumulation of charge carriers at a selected site may be controlled so as to be different from that at other sites. In an embodiment, selected sites 12b, 12d have a thicker insulating layer beneath the electrode, resulting in reduced charge carrier accumula- .tion compared with adjacent sites. The carriers may be provided by exposure of the substrate to light to form electron-hole pairs, or avalanching the electrodes and allowing the charges to reach equilibrium. This structure forms a read only memory, the readout in this embodiment being 0101. Alternatively the insulating layer may be of uniform thickness, the electrodes having different work functions, e.g. platinum and tungsten, to produce different charge accumulations. In an alternative embodiment the selected sites may have a thin area in the insulating layer alongside the electrode, the layer being covered by a biased metal layer, the thin areas accumulating charge in the substrate adjacent the site. This structure gives a read only memory. In a further embodiment the sites may form drain regions of a plurality of I.G.F.E.T.s having a common source region, the gate regions being confined to selected sites and connected together. As a result charge is accumulated only at the site provided with gates. In an alternative form a common gate is provided for all sites, the source regions being selected instead. In a further embodiment in which the information is not permanently arranged, conductive plates may be present at the interface of two insulating layers on a semi-conductor substrate. The plates may be selectively charged so that a desired memory pattern may be read from the sites located above the plates. Analog or digital information may be presented in this manner.

Abstract: 984,911. Variable resistors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. July 2, 1963 [Aug. 2, 1962], No. 29711/62. Heading H1S. Apparatus for adjusting a high electric current (of the order of hundreds of amperes) in a controlled manner comprises an elongate glass container 2 with side arms 2a, 2b sealed at each end by rubber bungs 4 which are pierced to support a tube 1 coaxially within the container 2. Terminals 5 are attached to each end of the tube 1 outside the container 2. Cooling water passes upwards through the tube 1 from an inlet 14 to an outlet 15. The side arms 2a, 2b are connected by flexible tubes 6, 7 to a sealed reservoir 8 containing a liquid metal 13 mounted on a support 9 which can be moved vertically on a column 10 of insulating material. The column 10 stands on a base 11 which also carries a support 12 of insulating material for the container 2. The height of the liquid metal 13 in the container 2 is controlled by the height of the reservoir 8 relative to the container 2. The liquid metal 13 acts as a movable contact on the tube 1 and, in the embodiment described, being mercury which has a resistance per unit length much less than the tube 1 which is of stainless steel, provides a preferred conducting path. The overall electrical resistance offered by the apparatus is therefore substantially that offered by the length A of the tube 1 above the liquid metal 13. The column 10 may be calibrated for accurate control of the reservoir position. In an alternative apparatus where the resistance per unit length of the liquid metal 13 is much greater (say n times) than that of the tube 1, the apparatus offers a range of control of about l/n times the resistance of the tube 1 and provides great sensitivity of control.

Title: Improvements relating to nuclear reactor control element operating mechanisms
Inventor: LAYCOCK WILLIAM
IPC: G21C9/027
Filed: 1965-07-14
Abstract: 1,106,436. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 8 July, 1966 [14 July, 1965], No. 29924/65. Heading G6C. A control element operating mechanism for a nuclear reactor comprises two portions, one incorporating a lift-lower mechanism and an electromagnet for supporting the other portion, and the other portion incorporating an armature for engagement by the electromagnet and a releasable mechanical coupling for engagement with a control element, either of fuel or a neutron absorber, a further releasable mechanical coupling enabling the armature and the electromagnet to be locked together. The two mechanical couplings are releasable by twisting in opposite directions. The further coupling, as shown in Fig. 5, comprises a pin 33 on the armature entering a peripherally extending slot 35 in a wall 36 secured to the electromagnet, the slot being open ended so that the pin can be disengaged from it thereby disengaging the coupling. An additional pin 32 and slot 34 are engageable when the pin 33 and slot 35 are disengaged in order to transmit a torque to engage the first mentioned coupling, which coupling is disengaged by a torque transmitted through the engagement of the pin 33 in the slot 35. This arrangement prevents the serious incident which might otherwise occur if the control element was in the core and the mechanism retracted, and the considerable portion of the mechanism between the electromagnet and the control element were to be released by the electromagnet to strike the core a severe blow, e.g. the control element might be rendered immovable or the components of a large region of the core might be locked together. In the embodiment described, coolant flows up a duct within the control element. The upper portion of the mechanism including the electromagnet and armature is housed in a doublewalled pillar, the space between the walls of which contains instrumentation cables and thermal and radiation shielding material.

Abstract: 1,109,463. Selective signalling. SPERRY RAND Ltd. 28 July, 1965 (28 July, 1964], No. 29998/64. Heading G4H. A photo-electrically sensed coded-scale position digitizer is characterized in that the source of light is controlled by a cell sensing a reference track so as to compensate for variations in the light transmission path. As described a coded cylinder is rotatable outside a fixed cylinder housing the photo-cells on its inner surface. Light is transmitted to the tracks of the scale individually from a single controlled lightemitting diode source by light guides. So as to increase the amount of light reaching the cells, a mask arranged between the coded cylinder and the cells has three slits-in phase with the bit spacing-for the low order tracks and a single wider slit for the high order tracks.
