Title: Fail-safe overload protective system for a load-handling vehicle
IPC: B66F17/00
Filed: 1976-03-29
Abstract: 1510291 Preventing tilting of load-handling vehicles ALLIS-CHALMERS CORP 29 March 1976 [3 April 1975] 12462/76 Heading G1N(A) To protect a vehicle 10 from tilting due to a load 31 the signal from a resistive strain gauge bridge G1-4, mounted on the pivot pin 24 of tilt jack 23 is fed to a comparator via differential amplifier OP1, the comparator produces a trip signal when the signal from amplifier OP1 exceeds a predetermined magnitude and a disabling control responsive to the trip signal prevents any further movement of the load to increase the tilting moment, the amplifier OP1 input being compensated by potentiometer R9 for the unladen weight of the platform and further incorporates means 8À5V via R14 to bias the amplifier output above said predetermined magnitude in the event of the leads between bridge and amplifier being severed. The trip signal is fed to a shift register SR which, each time a clockpulse is received from oscillator OSC, transfers the input signal to the first output and the previous data on that output to the succeeding output. When a predetermined number of outputs are registering the trip signal, thus indicating that it has been present for a predetermined time interval, a de-coder sets a latch which turns transistors Q 1 , Q 2  off and thereby deenergizes the operating coils 47, 50 of hydraulic valves 40, 44. Check-valve 49 then prevents discharge of fluid from the rod end of tilt jack 23 but allows supply of fluid; check-valve 52 blocks supply of fluid to lift jack 46 but allows discharge therefrom. A time delay circuit comprising capacitor C6, and diode Dl prevents false resetting of the latch due to noise or transient signals.

Patent GB-605442-A (GB)
Title: Improvements in or relating to the preparation of diaryl mercury compounds
IPC: C07F3/12
Filed: 1944-07-04
Abstract: Organic mercury compounds having germicidal and fungicidal properties are prepared by treating an organic mercury compound of the formula RHgX, where R is an aryl group and X is an anion of an organic or inorganic acid, with an alkylolamine in the presence of a decomposition inhibitor.  Preferred inhibitors which are used are organic carboxylic acids such as lactic and citric acids or salts thereof.  The function of the inhibitor is to prevent the premature deposition of the products of the invention which are insoluble.  The effect of the inhibitor may be overcome by heat and this property may be used to cause the deposition of the product of the invention in situ in fibrous materials such as textiles, fibres, yarns, paper, leather, films and sheets and to render such materials permanently germicidal, bacteristatic and fungistatic.  Starting materials of the formula RHgX which may be used include phenyl mercuric acetate, phenyl mercuric lactate, tolyl mercuric malate, and tolyl mercuric butyrate.  Alkylolamines mentioned include mono-, di- and tri-ethanolamines and mono-isopropanolamine.  The reaction is carried out by merely mixing the ingredients in aqueous solution.  In examples: (1) phenyl mercuric acetate, triethanolamine and lactic acid are mixed, and the product diluted with water containing citric acid to form a product suitable for treating textiles which yields diphenyl mercury on heating; (2)-(4) the product of example (1) is applied to textiles in admixture with other textile treating agents.
