Title: Improvements relating to temperature indicators
IPC: G01K5/62
Filed: 1929-11-30
Abstract: 346,360. Thermometers. SLOUGH, F. M., 602, B. F. Keith Building, Cleveland, Ohio, U.S.A. Nov. 30, 1929, No. 36801. Convention date, Nov. 30, 1928. [Class 97 (iii).] In apparatus for the remote indication of temperature, comprising a bimetallic element subjected to the temperature to be measured and arranged to close contacts when the temperature rises so as to complete a circuit including means for operating an indicator, one of the contacts is actuated by a second bimetallic element which is provided with a heating element included in the electrical circuit, the second bimetallic element being adapted on being heated to move its contact to break the circuit. The apparatus is particularly intended for measuring the temperature of the cooling water of an internal-combustion engine. In the form shown the bimetallic strip 26 is secured to a heat-conducting plug 17 projecting into the water jacket 3 and carries a contact 33 on a screw 36. The contact co-operates with a contact 32 carried by a bimetallic strip 13 on which is mounted a heating coil 16 the circuit of which is completed by closure of the contacts. The circuit also includes an electromagnet 12 co-operating with an armature 15 on the strip 13, and a heating coil 41 associated with a bimetallic strip 46 which actuates the pointer 42 of the indicator. Another bimetallic strip 45 is interposed between the strip 46 and the pointer, to compensate the indications for variations of atmospheric temperature. As the temperature of the strip 13 is raised by the coil 16 the contact 32 tends to move away from the contact 33 until the circuit is ultimately broken, the interruption of the circuit of the electromagnet 12 causing the contacts to separate with a snap action. Further heating of the strip 26 causes the contacts to close again, and so on. The position of the pointer 42 for a given temperature can be regulated by adjusting the screw 36.

In a method of producing starting sheets for the electrolytic recovery of copper, zinc or cadmium by electrolytic deposition of the metal concerned on to a cathode base sheet, the cathode base sheet is coated with an agent for preventing strong bonding of the deposited starting sheets to the base sheet, metal is electro-deposited on to the base sheet to form the starting sheets, forming a layer of air by a physical process between the starting sheets and the base sheets at one part thereof, and then stripping the starting sheets from the cathode base sheets by means of vacuum suction discs. The layer of air may be introduced between the starting sheets and the base cathode sheet by a rolling process, by vibration or percussion. Using the apparatus shown for separating the starting sheets 2 from the base sheet 1, the combination sheets pass on a conveyer between the arms 5 supporting vacuum suction discs 4. The arms 5 rotate about the parts 9 so that the suction discs 4 engage the starting sheets 2 on either side of the base sheet 1, reverse rotation of the arms 5 then stripping the starting sheets 2 from the base sheet 1. Prior to passage between the arms 5, the sheet passes between rollers 3 which serve to introduce air between the respective sheets over part of their area. The coating agent used may be a solution or an emulsion of one of the following compounds: - (1) An organic phosphoric acid compound having the formula where R = chain hydrocarbon radical, e.g. lauryl, stearyl, or oleyl; X = hydrogen, sodium, potassium or ethanol amine; and n = 1, 2 or 3.

Abstract: 895,708. Measuring velocity electrically. MAXSON ELECTRONICS CORPORATION. Nov. 5, 1959 [Nov. 10, 1958], No. 37574/59. Class 40 (1). [Also in Group XIX] Apparatus for measuring the velocity of a vehicle comprises a low friction nut 14 (Fig. 1) located on a threaded shaft 11 and associated with an E-type core 17 carrying a centre-tapped winding 18, whereby acceleration of the vehicle along the axis of the shaft 11 causes the nut to move along the shaft, thereby unbalancing the halves of winding 18 to produce a signal which is amplified at 25 and fed to a motor 10 driving the shaft, which changes speed to reposition the nut centrally with respect to the core 17. The speed of rotation of the shaft 11 and nut 14 is proportional to the speed of the vehicle, and may be indicated by, e.g., a tachogenerator, and also integrated to indicate distance travelled. In one embodiment (Figs. 8, 9, not shown) the motor drives the nut, and the shaft with an attached flywheel constitute the inertia mass. In a modification (Figs. 5, 6, not shown) a spring is attached between the shaft and nut to compensate for gravity when measuring vertical acceleration and velocity. A # component from a tachometer is added to the amplifier input to prevent hunting.

Title: Improvements in or relating to the manufacture of hydrazine hydrobromide
IPC: C01B21/16
Filed: 1954-12-30
Abstract: <PICT:0762569/III/1> Hydrazine hydrobromide is manufactured in a two stage cyclic process, by absorbing and reacting bromine and ammonia in an aqueous solution of ammonium bromide in a tower contact system and reacting the aqueous ammonium bromide solution, withdrawn from the tower, with hydrazine to form hydrazine hydrobromide and ammonia, the latter being returned to the absorbing and reacting step. Aqueous ammonium bromide solution, ammonia, and liquid bromine enter, through 5, 6, and 3 respectively, the bottom absorption section of tower 1, which is divided into four sections by bubble cap trays. The solution passes to reactor section, where further liquid bromine is added at 4, which is kept flooded and at atmospheric pressure and 60-70 DEG C. by heat exchange.  The reacted solution is withdrawn at 10 and part is recycled through 5.  The nitrogen evolved in the reaction escapes at 9 after scrubbing with water, entering at 8, in top two sections of tower 1.  The remainder of the ammonium bromide solution is passed through 11 to reactor 12, having an agitator into which hydrazine or concentrated (95 per cent) or dilute hydrazine solution, preferably hydrazine hydrate, passes at 13.  The contents of the reactor is continuously removed through 14, 15 to vacuum concentrator 16 and returned through 17.  Ammonia evolved is returned to tower 1 through 19.  The ammonium bromide should be in slight excess and may be passed through an intermediate surge tank to the reactor.  An aqueous hydrazine hydrobromide solution (70 per cent) may be withdrawn at 21, or the solution may be passed to vacuum evaporator 23 and the resultant fused water free salt passed to flaker 25 from which solid is recovered.  It is stated that the ammonia used in the preparation of the ammonium bromide may be aqueous ammonia.

Title: Novel saponin and process for the isolation thereof
IPC: C07H15/256
Filed: 1960-11-02
Abstract: The invention comprises cryptoaescin, a water-soluble saponin derivable from extracts of horse-chestnut, having an empirical formula C59H94 O27.H2O, a molecular weight of 1253, and containing besides one mole of cryptoaescigenin, one mole each of a -methyl-b -hydroxy-butyric acid, acetic acid, glucuronic acid, glucose and xylose as well as arabinose, said cryptoaescin being convertible by isomerisation from one form, viz. cryptoaescin A, m.pt 218-20 DEG C., into another, viz cryptoaescin B, m.pt 220-1 DEG C., and a process for the isolation of the saponin from an aqueous or aqueous-alcoholic extract of horse-chestnut from which cholesterol-precipitable saponins have been removed, by acidification, preferably to a pH<2, and recovery of cryptoaescin from the resulting precipitate and/or from the solution freed from the precipitate. The recovery step is preferably effected by extraction with an organic solvent, evaporation of the purified extract, extraction of the residue with water, treatment of the solution with a cation exchanger (if the organic extract was purified with alumina), extraction with butanol, evaporation of the butanol extract, treatment of the residue with methanol, treatment of the extract with charcoal and finally evaporation of the solvent to yield cryptoaescin A. The isomerisation of cryptoaescin A to cryptoaescin B is carried out by boiling in aqueous solution.ALSO:Cryptoaescin, a homogeneous water-soluble saponin isolated from horse chestnut extracts and exhibiting a strong action on the blood vascular system and diuretic and anti-histaminic properties, may be formulated with a non-toxic carrier for administration by injection.  Cryptoaescin exists in two isomeric forms, cryptoaescin A, which is non-haemolytic, and cryptoaescin B, which causes a harmless degree of haemolysis, and may be used to enrich an aqueous or aqueous-alcoholic horse chestnut extract from which the cholesterol-precipitatable saponins have been removed by treatment with cholesterol.  The horse chestnut extract freed from all saponin components, including cryptoaescin, is also useful therapeutically owing to the presence of other active constituents, notably flavorized compounds, e.g. flavonol glycosides.
