Title: Display device
IPC: G09B17/00
Filed: 1973-01-26
Abstract: 1421455 Educational appliances; display devices N HINDMARCH 21 Dec 1973 [26 Jan 1973] 3993/73 Headings G5C and G5G A display device comprises a base-board 1; a row of stacks of tumble-cards 2 hingedly mounted by means of ring-binders 3 on the baseboard, each tumble-card having a tab 7 on one edge and the tabs of each stack being arranged in a staggered manner; and a display card (Fig. 2, not shown) having projections (6) which, when the display card is positioned on the base-board 1, co-operate with selected tabs and thereby retain selected tumble-cards in place whilst allowing the overlying cards to tumble over when the base-board is tilted in the appropriate direction whereby visual information carried by the faces of the retained cards is exposed. As described, the device is adapted for use as a teaching aid, in which the display cards carry pictures and the tumblecards carry letters, the arrangement being such that the cards which tumble over spell the word corresponding to the picture on the particular display card in use (Fig. 3, not shown). In a modification, Figs. 4 and 5 (not shown), the tabs 7 are provided on the edges opposite the hinged edges of the tumble-cards rather than on the adjacent edges as in Fig. 1.

Title: Improvements in photoelectric measuring instruments
IPC: H02P7/347
Filed: 1959-10-29
Abstract: 929,715. Photo-electric gaugeing. M. C. PFISTER. Oct. 29, 1959 [Nov. 27, 1958], No. 4022/62. Divided out of 929,711. Class 40 (3). The width of an object is measured by scanning it in opposite senses by scanning heads as described in Specification 929,711, connecting the outputs in series, and measuring the sum output voltage with a self-balancing potentiometer. The axes of sensitivity of the scanning heads 54, 55, Fig. 3, are rendered perpendicular to the object 56 by a parabolic mirror 57. The outputs of the scanning systems 54, 55 are analogues of the distances X and Y so that the sum output equals G + b which, since G is constant, varies linearly with b. The outputs U54 and U55, Fig. 4, are connected in series and in opposition to a potentiometer 58 fed from a rectifier energized by the same mains as the scanning systems 54, 55. Any resultant current energizes a servomotor 61 to balance potentiometer 58. Servomotor 61 may also actuate an indicator or perform a process control. The object to be measured may be steel strip from a rolling mill or a rolled tube in which case scanning heads 54, 55 may be relatively displaced in the plane of Fig. 3.

Patent GB-1014045-A (GB)
Title: Electrodeposition of palladium
IPC: C25D3/52
Filed: 1964-01-31
Abstract: A palladium plating bath contains a palladium chelate of N:N1 cyclic alkane di-amino-tetraaceti acid and a soluble phosphate e.g. potassium mono-phosphate, which acts as conducting salt and buffer, maintaining the pH value in the range 4-12 and preferably 5-7.  The alkane group may be aliphatic e.g. cyclopropane, cyclobutane or cyclohexane. Deleterious impurity metals e.g. Ni, Cu, Fe, are precipitated as phosphates in the bath and are removed by periodic filtration.  The bath is replenished by adding palladium oxide which takes up released chelating agent. Plating is effected at room temperatures.  Citric acid may be added.

Abstract: 1,274,813. Jointing. C. A. NORGREN CO. 29 Jan., 1970 [10 Feb., 1969], No. 4251/70. Heading B3V. [Also in Division F2] In a valve construction wherein a landed spool is movable within a ceramic sleeve 12 which is coaxially disposed within, and is bonded to, the bore 44 of the valve housing 10, the sleeve and housing bore are so dimensioned as to form therebetween an annular space which contains the bonding agent. Bonding of the sleeve 12 to the bore 44 is effected by inserting suitably flanged plugs 48 into the ends of the sleeve such that the latter is centred within the bore, and inserting further plugs between ports 22 and psasages 24 in the sleeve and housing, respectively, the ports and passages in combination forming flow paths of the valve. Polyurethane, an interpolymer of butadiene and vinyl chloride or polyvinyl chloride is then injected into the annular space via narrow passages in flanges of plugs 48. Subsequent to curing, the plugs are withdrawn leaving a bonded sleeve.

Title: Improvements in and relating to safety locks
IPC: E05B29/00
Filed: 1924-02-19
Abstract: 223,119. Dorneth, J. Feb. 19, 1924. Locks, revolving-barrel; night latches and like spring locks; bolts; multiple-bolt fastenings.-A revolving-barrel lock with radially-arranged notched sliding tumblers operates two or more spring-shot bolts which are normally held retracted by a catch till the door is closed, when their springs shoot them and effect turning of the barrel to a position in which the tumblers engage fixed studs to lock the barrel. The revolving-barrel is composed of the key-barrel 5 journaled in the front and back plates of the lock and having rigidly secured to it the member 4 with slots p for guiding the tumblers 11. The tumblers 11 have notches l co-operating with fixed studs 2 arranged circularly on the baseplate 1. The part of these studs engaging the tumblers is semicircular. Each tumbler has two projections h entering holes in the key-barrel 5 to project into the bore to co-operate, with the key. The projections h fall one on each side of the partition k, so that if the outside projections are destroyed by tampering the inside ones remain intact. To operate the lock, the key is inserted into the key-barrel to align the notches L of the tumblers with the studs 2, when the barrel can be turned to cause the follower a to withdraw the bolts 7 from the staples 9 against their springs c. When the bolts are withdrawn a catch b pivoted to a bracket on the bolt is turned by the spring c to engage under the staple 9, as shown in Fig. 3, to hold the bolt withdrawn. When the door is opened, the shoulder d on the catch engages the plate 8, still holding the bolt withdrawn, ae shown in Fig. 4. When the door is slammed, the catch b is knocked out of engagement with the plate 8 by the staple 9, allowing the spring c to shoot the bolt. The necessary turning of the follower a and barrel to allow this shooting of the bolt is possible owing to the rounded backs of the pins 2 engaging the bevelled edges m of the tumblers 11 which are forced into releasing position against their spring 14 to allow the barrel to turn as the bolt shoots, after which they snap back into locking position. The bolts 7 have a tubular outer part with a revoluble inner core to prevent release by drilling.

Abstract: 608,060. Folding wing aircraft. FAIREY AVIATION CO., Ltd., CHAPLIN, H. E., and COSTIGAN, F. J. Feb. 14, 1946, No. 4661. [Class 4] The outboard portion b of an aircraft wing folds relatively to the inboard portion a about an oblique axis c-c so as to lie when folded in a vertical plane alongside the fuselage. A trailing edge flap on the wing comprises parts g and h separated along the stepped surface k, m, n, o, the part g being mounted on the fixed part a, and the part h on the folding part b of the wing. The parts g and h are connected by a hinge coincident when the flap is nested with the axis c-c so that the part h of the flap folds with the part b of the wing. Means locking parts a and b of the wing together and means locking parts g and h of the flap together, the latter comprising a tongue x on part h engaging in a socket w on part g and secured by a bolt y, are operated simultaneously. The nesting of the flap g, h, the unlocking of the wing and flap and their folding may form sequential steps of a single operation. A spring-pressed flap covers the cleavage between the parts a and b in the wing in the extended position. The fairings p, q house the linkages operating the flap g, h, each linkage comprising two links, one pivoted to the leading edge and one to the body of the flap and both pivoted on the wing at longitudinally separated points, each pivot for the leading edge links being operated by an electric motor.

Title: Process for the concentration of rock phosphate
IPC: C05B11/02
Filed: 1958-02-13
Abstract: Rock phosphate containing calcium carbonate is treated with an unsaturated aqueous solution of sulphur dioxide to convert at least a major portion of carbonate to bisulphite, and the calcium bisulphite solution separated from the undissolved phosphate.  The process may be carried out by passing gaseous SO2 through a rock phosphate slurry, said SO2 being either substantially pure or diluted with oxygen-free gases, e.g. nitrogen.  From the calcium bisulphite solution, e.g. after heating to 75 DEG  C., SO2 may be recovered by introducing hot gases inert towards the bisulphite, e.g. flue gases; the SO2 thus liberated may be recycled and the calcium sulphite formed at the same time and precipitated may be a useful by-product or may be worked up for SO2 recovery.
