Abstract: 905,017. Batteries. ACCUMULATORENFABRIK A.G. Dec. 17, 1958 [Dec. 21, 1957], No. 40661/58. Class 53. A permanently gas- and liquid-tight alkaline accumulator has a finely porous electrode separator in which an alkaline electrolyte is held by capillary action, the negative electrode including an antipolar mass, the reducible part of the positive electrode being greater than the oxidizable part of the negative. The antipolar mass may be a hydroxide of nickel, cobalt or copper. An antipolar mass such as cadmium oxide or hydroxide may be added to the positive electrode. The active mass of the electrodes may be contained in perforated pockets or tubes, e.g. of nickel-plated steel, or may be introduced chemically or electrochemically into a sintered body, e.g. of nickel powder, or may be formed by compressing a starting material, if necessary with a conducting material. The form shown comprises a separator 8 of fabric, paper or porous regenerated cellulose or synthetic resin. The electrodes 6, 7 are connected to the insulated parts 1, 2 of the casing by metal members 4, 5 which are also porous to assist the reduction of oxygen formed during charging. A stack of similar assemblies, parallel connected, may be placed in a rectangular casing or a thin elongated flexible assembly rolled into a cylindrical easing.

[Also in Divisions B7 and F2] An air buoyancy conveyer comprises a number of normally closed valves 17, Fig. 1, arranged over the floor 4 and arranged to produce pre-oriented jets of air under the control of a proximity detection system when an object 6 to be conveyed is in the region of the valves. In the example, the valves 17 are actuated by the air pressure beneath the object 6 produced by air from previously opened valves. Each valve comprises differential pistons 11, 13 slidable in bores 14, 15 and having a central passage 18, 19, whereby pressure air is released from a plenum chamber 2 beneath the floor when the air pressure beneath the object 26 causes the piston 11 to be depressed. The valves may have oriented passages 31, Fig. 3 (not shown), for directing the jet of air forward or sideways to guide or propel the object 6. Projections 34 are also formed on some of the valves for mechanical engagement by the object 6 at the loading point so that the system is self-starting. In a modification the piston-actuated valves may be substituted by flexible diaphragms 37, Fig. 6 (not shown), which are pressed into recesses 14 in the floor 4. Groups of valve plungers 56 may be formed integrally with or mounted in a flexible sheet 53 of plastic or metal.

Apparatus for generating from an input television signal an output signal of a different line frequency or phase comprises a plurality of storage means (for example low-pass filters or delay lines) equal in number to the number of picture elements into which a scanning line is to be resolved, a first switch operated to scan all the storage means in succession at a line repetition frequency equal to that of the input signal and to apply to each storage means a voltage or current representative of the amplitude of the input signal at the time of scanning, and a second switch operated to scan all the storage means in succession at a line repetition frequency equal to that of the required output signal and to apply to an output terminal at the time of scanning a voltage or current representative of the voltage or current in the storage means at the time of scanning. The embodiment shown is for converting from 625 to 405 lines and thus comprises 600 low-pass filters 35 which have a sin<SP>2</SP># time response although filters possessing a sin #/# or a linear time response are also said to be suitable (Fig. 3, not shown). For convenience both the first and second switch means comprise a plurality of switching elements connected in cascade. Thus the first switch means comprises the pulse generator 28, 18 diode bridges 28 and 600 transistors 34 while the second switch means comprises a similar arrangement of generator 38, bridges 40 and transistors 36. The synchronisation pulses are separated from the video input signal by the separator 27 and are used to trigger pulse generators 28, 38. Each of these produces two pulse trains x 1 , y 1  and y 2 , y 2  the phase and frequency of these being such as to switch the switching elements previously described in the correct sequence.
