Filed: 1936-10-12
Abstract: <PICT:0482903/III/1> <PICT:0482903/III/2> A method of proofing or coating hollow articles such as paper bottles, cups, or containers, in which the containers are carried into, through and out of a body of liquid by angularly displaceable arms moving in a vertical plane, is characterized in that the containers are placed mouth downwards over the free ends of the arms when the latter are above the surface of the liquid and are caused to enter the liquid and emerge therefrom with their mouths down and with a tilting movement such that buckling or crumpling of the walls of the containers is avoided.  An apparatus for carrying out this process is shown, comprising a bath 2 of coating liquid, e.g. paraffin wax, and a rotatable spindle 4 carrying radial arms 6 to support the containers A.  The axis of rotation of the spindle 4 is slightly above the level of the liquid, and the spindle may be intermittently rotated by pressure upon the pedal 10. Heaters 3 may be provided, and the bottom of the bath may be curved, or curved guides may be provided thereon against which the bottoms of the containers may bear during their passage through the liquid.  The arms 6 may all be arranged in one plane, or a plurality of staggered sets of arms may be provided along the length of the spindle 4. According to the Provisional Specification, the arms need not move entirely in a vertical plane, but may be caused to move through the liquid in a substantially horizontal position.

Title: Improvements in or relating to shaft couplings
Inventor: SOUTHERN LESLIE
IPC: F16D7/04
Filed: 1957-09-02
Abstract: 843,358. Positive clutches; shaft couplings. GENERAL ELECTRIC CO. Ltd. Aug. 25, 1958 [Sept. 2, 1957], No. 27688/57. Class 80 (2). A positive clutch for controlling the position of a radar aerial maintains a predetermined rotational correspondence between the driving and driven shafts 2, 5 within a predetermined finite and limited angular range (Œ 60 degrees) of the driven member, whilst permitting rotation of the driving shaft 2 alone outside the predetermined range when the torque opposing rotation of the driven shaft exceeds a predetermined value, the correspondence being restored within the range after rotation outside the range. A cam follower 13 freely rotatable on one arm of a bell crank 10 pivoted at 12 to a gearwheel 7 driven from the driving shaft 2 is biased outwards by a spring 8 into engagement with a heart-shaped cam 17 fast on the driven shaft 5 and constrained to rotate within a range Œ 60 degrees from a fixed datum 5a by stops 18 ... 20. For a rotation of the driven shaft 2 within the said range from a fixed datum 2a the cam follower 13 engages a recess 17b in the cam and rotates the latter through a corresponding angle in the opposite direction. When the driving shaft is rotated out of the predetermined range in an anticlockwise direction the stop 18 abuts the stop 20 and the cam follower 13 rolls out of the recess and round the cam surface 17, the force exerted by the cam follower 13 on the cam 17 maintaining the cam in its limit position until either the driving shaft is rotated in the opposite direction to roll the cam follower into the recess whereupon the rotational correspondence is resumed, or the cam follower passes over the cusp 17a whereupon the force between the cam follower 13 and cam 17 is in the opposite direction and rotates the cam to its other limit position in which the recess 17b is in position to receive the cam follower 13 when the shaft 2 re-enters the range. The cam 17 is asymmetrical about a diameter through the cusp to allow for the force exerted by the cam follower on the cam not being radial. The wheel 7 may be fast with the driving shaft 2 or the gears 3, 7 may have a ratio other than 1 : 1.

Filed: 1973-06-11
Abstract: 1401093 Anode for acid electrolyte storage battery SAFT-SOC DES ACCUMULATEURS FIXES ET DE TRACTION 11 June 1973 [9 June 1972 (2) 23 Nov 1972] 27702/73 Heading H1B The active material for the anode of a battery having H 2 SO 4  as electrolyte and PbO 2  as active material for the cathode, comprises both in the charged and discharged state simple or mixed oxides of molybdenum, the average valency of the molybdenum in the oxides being greater than or equal to four and less than or equal to six. As an example, in the discharged state the oxide is MoO 3  which is reduced on charging to become MoO 2 . In another system, MoO 3  is reduced to MoO 2À17  which represents the mixed oxides MoO 3 . 5MoO 2 . In other systems in which the oxide in the reduced state is MoO 2 , the oxidized state is represented by the mixed oxides MoO 3 , 3MoO 2  or MoO 3 .4MoO 2  or MoO 3 .5MoO 2 , equivalent, respectively, to MoO 2À25 , MoO 2.2  and MoO 2À17 . The use of a molybdenum oxide active material for the anode instead of Pb as is conventional, facilitates the construction of a sealed battery in that a smaller quantity of H 2 SO 4  is required and less gas is generated. The electrolyte density is preferably in the range 1À20-1À40. In the cell shown in Fig. 6, the anode comprises two ring-shaped members 11, 12 each consisting of a mixture of MoO 3 , graphite, and PTFE and made by compressing powders of these materials, these rings being placed inside a graphite cylinder 13 acting as current collector. The cathode 14 comprises PbO 2  placed within a porous tube and the separator 15 comprises felted propylene fabric. The beaker 16 is filled with H 2 SO 4 . In other constructions of the anode (not shown), the active material is compressed on to a support of gold-plated tantalum or silver, accommodated in the pores of a graphite support, or accommodated in a tube of plastics material. The graphite support may comprise felted or woven carbon fibres. The conductive material mixed with the molybdenum oxide may alternatively comprise silver-coated graphite, soot, titanium nitride, silver, or silver-coated copper powder. To further reduce the gas liberated, the cathode may have excess capacity which is precharged so that this excess capacity remains charged when the battery is completely discharged; also, the capacity of the negative electrode (anode) is such that part of the anode remains uncharged when the battery is fully charged. The charge of voltage on the anode during discharge from one oxide state to another may be sensed and used as a signal to stop the discharge.
