Title: Improvements in or relating to means for depositing films of metal on a series of plates or sheets
IPC: B05B13/02
Filed: 1945-10-15
Abstract: In a method of depositing films of metal on a series of plates by spray painting, each plate is held during the spraying operation in a jig which is employed solely for the purpose of supporting the plate while it is being sprayed.  As shown, applied to an apparatus for spraying silver on mica plates, a nozzle 20 connected to a suction line 22 automatically removes a plate 12a from the top of a stack in a magazine 13 and transfers it to a jig 4 mounted in a base plate 9 above a spray gun 8 which may be rocked.  The nozzle 20 remains in contact with the plate 12a during the spraying operation and is removed immedi <PICT:0596838/III/1> ately afterwards, suction having been cut off.  A second suction nozzle 87 then moves the coated plate 12b from the jig and transfers it to a rack, Fig. 1 (not shown), where it is deposited. The timing of the various operations is controlled by a series of cams operated by a continuously rotating shaft 2.  A second similar spraying operation may be provided if both sides of the plate have to be coated and the coating may be followed by a heating or drying operation.

Title: Battercy discharge indicators
IPC: H01M50/569
Filed: 1971-06-11
Abstract: 1400391 Battery discharge indicator SEVCON Ltd and L MOLYNEUX 9 June 1972 [11 June 1971] 27531/71 Heading G1U [Also in Division H3] A system of the type in which in order to detect when a battery is discharged, this being defined as being when the no load voltage falls below a predetermined level, a voltage which is a function of both the battery voltage and the battery current is compared with a pre-set level, is characterized in that the battery current is sensed by sensing the magnetic field produced by it, in order to minimize wasted power. In a first embodiment, Fig. 4, a fraction of the battery voltage across terminals 32, 34 is extracted by a potential divider comprising resistors 210, 212 and a magneto-responsive resistor 10 situated in the field of the battery current, and applied to the right-hand input of a long-tailed pair comparator 208, 204, the left-hand input being pre-set by a potentiometer 200 across a Zener 42 stabilized supply 32, 36. If the fraction of the battery voltage is larger than the pre-set value the left-hand side of the comparator is maintained non-conductive, and a bi-stable transistor pair 214, 216 is set so that a green lamp 220 is lit. If the fraction of the battery voltage is below the pre-set value, the opposite situation obtains and a red lamp 218 is lit, indicating that the battery is discharged. If the battery current rises, thereby causing the battery voltage 32, 34 to fall, the resistance of the element 10 rises so that the value of the fraction of the battery voltage applied to the comparator is substantially unchanged. Thus the arrangement effectively monitors the battery no load voltage irrespective of any current drawn from the battery. In a second embodiment Fig. 1 (not shown) the fraction of the battery voltage is monitored by an SCR, (88) which fires if the fraction becomes too small, and which, when fired, forms part of a relaxation oscillator (56, 66) causing a lamp (84) to flash, indicating discharge, and holding unenergized a second lamp (106). The Specification also outlines an arrangement, Figs. 2 and 3 (not shown) in which the magneto-responsive resistor is mounted in the airgap (20) of a wrought iron block (14) containing a hole (16) through which the main current conductor from the battery passes.
