Title: Improvements in or relating to magnetic positioning devices for electric switches and keys
IPC: H01H5/02
Filed: 1956-07-26
Abstract: 809,090. Switches, partly magnetic; magnetic switches; tapping keys; switches held set and freed mechanically; mechanical switches without quick action. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 26, 1956 [July 29, 1955], No. 23139/56. Class 38 (5). A pair of relatively movable co-operating permanent magnets are provided in a switch to determine at least one switching position of the switch operating member, each magnet having a coercive force of at least 750 oersted. The magnet material is preferably as disclosed in Specification 708,127, [Group XXXV]. In Figs. 1, 2, an annular permanent magnet 7 is rotated by a shaft 2 within a fixed magnet 6, the magnets having poles as shown, whereby the shaft is held in positions spaced by 90 degrees due to attraction between poles of opposite polarity, rotation of the shaft causing tilting of the mercury contact tube 5 carried thereby. According to Fig. 3, the shaft part 3 is rigidly connected to the mercury tube carrier 4 whilst the driven end 2 is freely rotatable in the carrier and carries an annular magnet 9 rotatable within a magnet 10 fixed to the carrier. The magnets 9, 10 are polarized similarly to the magnets 6, 7 but are stronger, whereby rotation of shaft 2 overcomes the resistance offered by 6, 7 and the tubes 5, 8 are quickly advanced to their next 90 degrees displaced position. In a further modification, Fig. 5, employing three concentric magnets 9, 10, 6, magnet 9 is driven by shaft 2, magnet 10 is fixed to the rotatable tube carrier, and magnet 6 is fixed to the switch housing 1. In a push-pull switch, Fig. 7, a disc-shaped magnet 30 on the operating plunger 27 cooperates with permanent magnets 31, 32 magnetized as shown to locate the plunger in any one of three positions, springs 25, 26 biased against the plunger head 29 operating changeover contact springs 21 ... 24. In a tapping key, Fig. 9, the lever 35 operating a contact 38 to engage contact 37, carries a magnet 40 co-operating with an adjustable magnet 41 whereby the lever is held in the position shown.
Patent GB-321653-A (GB)
Title: Improvements in or relating to starting apparatus for internal combustion engines
IPC: F02N15/06
Filed: 1928-08-11
Abstract: 321,653. White, A. E., (Delco-Remy Corporation). Aug. 11, 1928. Turning-gear. - An engine starter comprises a rotatable driving member 46 movable axially into driving connection with an engine member 80, manual means for turning the driving member to effect driving engagement with the engine member, a device such as a spring 53 for yieldingly pressing the driving member against the engine member while the driving member is being manually turned, and means for automatically disconnecting the driving member from the engine member when the engine starts. As shown, the driving member 46 is a pinion in engagement with helical splines 45 on a sleeve 44 slidable on the longitudinally splined shaft 40 of the starting motor. The pinion 46 is moved axially by a lever 63 acting through the spring 53, which is enclosed in a housing 55, 57 and bears at its ends against the part 55 of the housing and a washer 52 on the end of the sleeve 44. If the teeth of the pinion clash with those of the engine member 80, the continued axial movement of the helicallv splined sleeve 44 turns the pinion until its teeth are in position for meshing. The circuit of the starting motor is closed by a contact 32 on a plunger 30 engaged by an adjustable screw 65 on the lever 63. When the engine overruns the starter, the pinion 46 is automatically disengaged by the helical splines 45 and is retained by a spring catch 50. Reference has been directed by the Comptroller to Specification 209,390.

Title: Improvements in or relating to printed self adhesive labels
IPC: C09J7/21
Filed: 1954-08-10
Abstract: 760,645. Ornamenting. PIRIE, APPLETON & CO., Ltd. Aug. 10, 1954 [May 3, 1954], No. 23236/54. Class 93. [Also in Group XVI] A process for making printed adhesive papers consists in spreading a solution of the adhesive on a protector paper treated or coated in such a manner that the adhesive does not adhere to the surface to which it is applied evaporating the adhesive solvent and after evaporation of the solvent, applying the adhesive coated face of the protector paper on to the printed face of a paper suitable for use with pressure sensitive adhesives. A protector paper which may be transparent or translucent is coated with protective varnish not clinging to the adhesive applied or uncoated papers may be used which have been treated with materials such as silicone resin or cellulose acetate. The solvent of the adhesive on the protector paper is evaporated in a drying tunnel and the paper is applied to the printed paper by simple pressure by passing between pressure cylinders. To use the printed paper the protector paper is stripped from the surface and the adhesive surface applied to the inner surface of a transparent object such as a shop window.

Filed: 1953-08-28
Abstract: A self-igniting propellant comprises at least one acyclic primary or secondary mercaptan of 1-5 C atoms and an oxidizing agent consisting predominately of fuming nitric acid.  A minor proportion of a tertiary mercaptan and a liquid hydrocarbon fuel may also be present. An ignition accelerator such as a sulphuric acid, nitrosyl sulphuric acid or nitrogen dioxide may be present in the nitric acid.  The mercaptans may be obtained by separating mercaptans from thermally cracked naphtha and fractionally distilling the separated mercaptans to recover a fraction boiling within the range from 125 DEG -300 DEG F.

[Class 18] Pressure sensitive adhesive tape is engaged and fed from a supply roll 22 by fingers 32 extending from the edge of a wheel 31 rotated, through a pawl 46 and ratchet 35 mechanism, by an arm 42 on which is mounted a device which severs the tape as the arm is actuated. The tape supply 22 is wound on a castellated core 23 supported between two discs 14, 19 mounted on a sleeve 13 which rotates about a spindle 12 secured to a supporting plate 11. The tape is fed round an idler roller 38a to the wheel 31, the adhesive side of the tape being engaged by the fingers 32 so that the tape extends from the edge of one finger to the edge of the next. A ratchet wheel 35 is fixed to the wheel 31 and coacts with a pawl 46 mounted on the lower end of the arm 42. The arm 42 and wheel 31 are mounted on a spindle fixed to the plate 11 and a spring 54 extends between the arm and plate 11 to retain the arm against a stop 51. Associated with the arm 42 is a cutter blade 68 attached to a plate 61 slidable on the arm. A pin 63 projects from the plate 61 and engages a sloping plate 73 pivoted to the plate 11 so that as the arm 42 is actuated, the pin 63 engages the sloping plate 73 to slide the plate 61 downwardly and to cause the cutter blade 68 to pass between two of the fingers 32 and sever the tape. At the same time the pawl 46 engages the ratchet wheel 35 to rotate the wheel and extend the tape to a position where it can be removed. A second stop 52 for the arm 42 is positioned so that the pawl and ratchet mechanism can only rotate the wheel 31 to dispense a length of tape extending between two fingers. A cover may be provided for the dispenser.
