Title: Battery discharge indicating system for use in an industrial truck
Inventor: TEDD DAVID CLIFFORD
IPC: G01R31/36
Filed: 1966-01-14
Abstract: 1,148,931. Control systems for battery operated trucks. EATON YALE & TOWNE Inc. 19 Dec., 1966 [14 Jan., 1966], No. 1825/66. Heading H2H. A system for use in an industrial truck comprises means for providing an indication that the battery of the truck is discharged, the means being disconnected under conditions wherein the current taken from the battery by the truck is such as to cause the battery voltage to fall below a given value. An industrial truck is driven by a traction motor 14, 15 energized by a battery 13, the truck speeds being determined by a tapped series resistor 16 and switches 17-19 operated by relays 21-23. The battery 13 is connected to resistors 29, 31 having a Zener diode 34 and resistor 35 connected in parallel thereto. Whilst the battery voltage is above a predetermined value the Zener diode 34 conducts, causing conduction of a transistor 37, non- conduction of a transistor 41 and de-energization of relay 42. If the battery voltage falls below the predetermined value the Zener diode 34 becomes non-conductive, the transistors 37, 41 assume their alternative states such that the relay 42 is energized so providing an induction of low battery voltage. In order to prevent a fake indication of low battery voltage when a heavy current is being drawn from the battery such as when the truck is being driven at other than slowest speed a contact 28 is added to the relay 21 so that when the relay 21 is energized to close contact 17 to select second speed contact 28 is opened to disconnect the indicator system from the battery. The indication may be given by a contact 42a on the relay 42 which is operable to stop the lifting mechanism 51 of the truck.

[Also in Division G3] The current flowing in a high pressure discharge lamp 1 is maintained constant at a desired value by comparing two voltages one from a device 10, representing the desired lamp current and the other, from a device 9, and derived from a resistor 3 in the lamp circuit, which is representative of the actual lamp current, the difference between these two voltages being used to control the duration of the impulses produced by a multivibrator 8 which in turn controls the mark-space ratio of a transistor 4 in the lamp circuit. The multivibrator 8 is normally controlled at the line frequency of the A.C. supply by a phase shifting device 7. Alternatively, the phase shifting device may be used to control the power rectifier 5 which may comprise silicon controlled rectifiers whilst the multivibrator may be of the self-oscillatory type. When light emission from the lamp is not required the lamp is supplied with a current of low value over a second transistor 11 in order to keep the lamp ready for instant operation. A high-frequency starting device 15 is provided which is utilized by way of a switch 2, this switch also being used to connect the lamp to the output of the rectifier 5 over a resistor 16 and an inductor 17.

Title: Analysis or other processing of gaseous fluids
IPC: G01N35/08
Filed: 1959-01-19
Abstract: <PICT:0902143/III/1> Gases are analysed in respect of a particular ingredient by conducting a fluid containing said gas or a derivative thereof through one side of a dialyser, conducting a liquid through the other side of the dialyser (whereby a portion of said ingredient or a reaction product thereof passes into said liquid) and thereafter through a colorimeter for analysis, a colour indicator being added to or present in said liquid prior to entry into the colorimeter.  The actual result of the analysis, which may not be made available, may be employed in a control operation.  As described, the invention is applied to gases containing HCN or HCl.  In a first embodiment (see Fig. 1) a gas containing HCN is passed into line 24 of a tube pump 10 of known construction and sodium hydroxide is passed through tube 26. The streams meet in 25 and form a segmented fluid stream which is passed through a mixing coil 12 and then through one side of a dialyser 14.  A similarly produced segmented stream of air and sodium hydroxide is passed to the other side of the dialyser and taken off through line 22.  An alkaline picrate indicator solution is added to this stream and the mixture passed to a mixing coil 16 and heating coil 18.  Thereafter the fluid stream is passed to a blending vessel 39 to remove the air before analysis in colorimeter 20 having a recorder 22.  In an alternative flow system (Fig. 3, not shown), the gas is contacted with sodium hydroxide outside the apparatus and the NaCN-containing stream segmented with air and mixed with distilled water before being conducted through the dialyser; an alkaline picrate indicator segmented with air is passed to the other side of the dialyser and the stream analysed as before.  In a second alternative (Fig. 4, not shown) for analysis of gases containing HCl, water is employed in the place of the sodium hydroxide used as the second liquid in connection with Fig. 1, a saturated mercuric thiocyanate solution takes the place of the alkaline picrate solution, a ferric ammonium sulphate solution is added after the segmented liquid passes from coil 16, and heating coil 18 is replaced by a second mixing coil.  Specifications 774,711, 827,924 and 827,925 are referred to.

Abstract: 304,667. I. G. Farbenindustrie Akt.- Ges. Jan. 23, 1928, [Convention date]. Addition to 286,603. Drawings to Specification. Apparatus for making filaments.-The manufacture of a loose untwisted band containing a large number of artificial filaments as described in the parent Specification, is modified as regards the washing &c. operations so that elongation of the filaments due to their loading with liquid in the passage of the band between the carrying drums, is avoided by suitable adjustment of the distance between the drums, and the rate of supply and points of application of liquid, in accordance with the speed of draft and thickness of the band. In particular, the liquids are applied at points in the upper halves of the stretches of the band between the drums of a pair, both of which are driven, thereby reducing the loading on the rising side, and permitting more efficient washing &c. treatment by reason of the opening-out that occurs on the falling side of the band. The factors are preferably so arranged that the natural shrinkage, referred to in the parent Specification, that occurs during the liquid treatments and during drying, is not permitted to take place or allowed to occur to only a limited extent. The tensions so produced, have a favourable influence on the physical properties of the product.
