Title: Improvements in or relating to holding means for cards or sheets of paper, cardboardor similar material
IPC: B42F17/18
Filed: 1947-12-12
Abstract: 652,040. Filing paper &c. sheets. KEESING, 1. Dec. 12, 1947, No. 32846. [Class 146 (i)] [Also in Group XVIII] A holding device for attaching cards or the like to a carrying member comprises a holding member with which is engaged a fastening member, one member being integral with or fixed to the card and the other member to the carrying member, the holding member comprising two substantially flat strips connected along one edge and enclosing an acute angle, at least one of the strips having an inwardly bent hook shaped flange, at an acute angle, to form a retaining member and the fastening member comprising at least one strip having a hook shaped flange, at an acute angle, along one edge, the fastening member being pushed between the two strips of the holding member till the flanges on the members snap into engagement with each other. As shown in Fig. 10, the carrying member comprises a series of strips 10 across which a number of holding members 30 are secured, having two retaining flanges 33 and each card 34 has an integral flange 36 and a flanged strip stapled to it to provide a second flange 36 to engage the flanges 33. When only one flange 33 is provided, no extra strip is provided on the card, and the card, as in Fig. 7, may have a longitudinal slot 26 to facilitate bending of the card and flexible strips 27 connect the two parts. The holding member 30 may be two strips secured together along one edge by pasting and/or stitching or stapling. Staples may be provided at the ends to prevent unbending of the strips. As shown in Fig. 13, each card 41 has a strip stapled to one edge and the edges of card and strip turned inwardly to form retaining flanges 40, while the fastening members 39 are secured to the carrying member 10 and comprise a doubled strip with out-turned flanges 38. The carrying members 10 form with the cards a storing device and the cards overlap to form a card index system. A loose leaf book, shown in Fig. 14, may be formed as the carrying member 42, holding members 43 being secured to the back of the binding and spaced by dummy strips 44, and cards 34 as pages in the book being provided as in Fig. 10. The pages in the book 42 may be provided with strips of adhesive or further holding members across the page so that photographs or other smaller cards may be secured to each page.

Title: Molybdenum compounds and lubricating compositions containing them
Inventor: BRETHERICK LESLIE
IPC: C08F10/00
Filed: 1963-08-20
Abstract: A lubricating composition consists essentially of a blend of a mineral or synthetic lubricating oil and a compound of the formula <FORM:1041019/C4-C5/1> where R1 and R2, which may be the same or different, are alkyl, alkenyl, or alkynyl groups preferably having 1-20 carbon atoms, and the X's are oxygen or sulphur atoms, at least one of the X's being an oxygen atom.  Preferably R1 and R2 are alkyl groups, especially branched chain alkyl groups, but where R1 and/or R2 are alkenyl or alkynyl groups, the group(s) may contain more than one multiple bond.  The molybdenum compounds are suitably used in an amount of from 0.1 to 5% by weight of the lubricating composition. In the examples, lubricating compositions are prepared from an SAE90 refined mineral lubricating oil and one of dithiomolybdenyl acetylacetonate, dithiomolybdenyl stearoylacetonate, dithiomolybdenyl lauroyl - pivaloyl - methanate or dithiomolybdenyl oleoyl-pivaloyl-methanate.ALSO:The invention comprises compounds of the Formula I <FORM:1041019/C2/1> where R1 and R2, which may be the same or different, are alkyl, alkenyl or alkynyl groups preferably having 1-20 carbon atoms and the X's are oxygen or sulphur atoms, at least one of the X's being an oxygen atom.  Preferably, R1 and R2 are alkyl groups, especially branched chain alkyl groups, but where R1 and/or R2 are alkenyl or alkynyl groups, the group(s) may contain more than one multiple bond.  They may be prepared by reacting a compound of the Formula II <FORM:1041019/C2/2> wherein R1, R2 and X are as above, with sulphur in an inert atmosphere preferably in a solvent and at an elevated temperature which is preferably between 100 DEG  and 200 DEG  C.  A suitable solvent is the diketone shown chelated in Formula I.  An alternative method of preparation is to react molybdenum hexacarbonyl with sulphur and a diketone or monothiodiketone of the formula R1C(X)CH2C(X)R2, where R1, R2 and X are as previously stated.  In this method the reaction mixture generates its own inert atmosphere of carbon monoxide.  In the examples dithiomolybdenyl acetyl-acetonate is prepared by the reaction of molybdenum triacetylacetonate with sulphur in acetylacetone and solvent and also by the reaction of molybdenum hexacarbonyl with sulphur and acetylacetone, dithiomolybdenyl stearoylacetonate is prepared by reacting molybdenum hexacarbonyl with stearylacetone and sulphur, dithiomolybdenyl lauroyl-pivaloyl methanate is prepared by reacting molybdenum hexacarbonyl with lauroyl-pivaloyl-methane and sulphur and dithiomolybdenyl oleoyl-pivaloyl-methanate is prepared by reacting molybdenum hexacarbonyl with oleoyl-pivaloyl-methane and sulphur.  The molybdenum compounds of the invention are used in the preparation of lubricating compositions (see Division C5).

Title: Improvements in or relating to microwave switching circuits
IPC: H01P1/11
Filed: 1961-09-14
Abstract: 912,867. R.F. couplings. WESTERN ELECTRIC CO. Inc. Sept. 14, 1961 [Sept. 30, 1960], No. 33051/61. Class 40 (7). A micro-wave radio frequency switching arrangement for connecting one of two sources to a common load, whilst simultaneously coupling an energy absorber to the other, comprises a circulator device 11 with the first source 12, the second source 20 and the load 13 connected in sequence to branches thereof. Each branch of the device is able to receive energy from the next preceding branch and to transmit energy to the next succeeding branch but is otherwise isolated. Between the source 20 and the device 11 is arranged an isolating and absorbing device 19 which transmits energy from the source towards the device 11 but absorbs any energy flowing towards the source. Finally a radio frequency switch 18 is positioned between the isolator 19 and the device 11 of the type which either transmits energy in both directions or reflects back energy fed to either side thereof. Considering first the condition with the switch transmissive, energy from source 20 passes to the load 13 and energy from source 12 flows through the switch and is absorbed at 20. With the switch reflective, energy from source 20 is reflected by the switch and absorbed at 20 whilst energy from source 12 is reflected back into the circulator and reaches load 13. If required an additional circulator branch may be provided following the load branch and terminated by an absorber so that if any energy is reflected back by the load due to mis-match this will not reach and affect the source 12. The switch 18 may be controlled by means sensitive to the proper functioning of source 20 so that if output therefrom ceases the source 12 is automatically connected to the load. It is an advantage of the arrangement that the source which is not feeding the load may be removed for service without affecting the operation of the other. The Specification indicates the nature of devices which can be used as circulators, isolators and switches. Preferred devices incorporate ferrite elements.
