Patent GB-818519-A (GB)
Title: Protein complexes
Filed: 1955-09-15
Abstract: Proteinaceous materials are protected from heat or chemical denaturation by adding a completely or partially fluorinated aliphatic acid, amine, alcohol or alcohol derivative, having at least two carbon atoms or a salt thereof, which provides an anion or cation with a non-polar group when in aqueous solution, to a solution of proteinaceous material to form a fluoro compound-protein complex, the resulting solution having a pH such that the fluorinated compound and the proteinaceous material carry like charges, i.e. above the isoelectric point when a fluorinated acid or alcohol is used, and below the isoelectric point when a fluorinated amine is used, and being capable of being heated to an elevated temperature, e.g. to sterilize the protein, or to which a potentially denaturing substance may be added without denaturation of the protein.  The proteinaceous material, e.g. ovalbumin, gelatin, human serum albumin, fibrinogen, bovine gamma globulin, beta lactoglobulin, viruses, antitoxins or enzymes such as urease, may be extracted from the complex by dilution, dialysis or ion exchange procedure.  Specified fluoro-compounds are perfluoro-butyric, -caproic, -caprylic, -capric, and -lauric acids and the corresponding acids in which the omega fluorine atom is replaced by hydrogen, together with omega hydro perfluoro-pelorganic, -undecoic, and -tridecoic acids and salts thereof; alpha-dihydroperfluoro aliphatic acids having four to twelve carbon atoms and alphadihydro perfluoro aliphatic amines having from two to twelve carbon atoms and their salts, e.g. hydrochloride, hydrobromide, sulphate, and phosphate.  The term "alcohol derivative" is defined as a partially fluorinated aliphatic alcohol of formul (i) ROSO3H, (ii) ROSO2X, and (iii) RSO3H and their salts, where X is a metal or ammonium, R is a fluoroalkyl radical containing at least two carbon atoms, e.g. fluoro-butyric, -caproic, -caprylic, -capric or -lauric radical.  Specification 818,520 is referred to.

Title: Improvements in or relating to a Coding System
IPC: H03M1/00
Filed: 1967-06-09
Abstract: 1,177,293. Analog/digital converters. FUJITSU Ltd. 9 June, 1967 [10 June, 1966], No. 26862/67. Heading G4H. An encoder for converting an analogue signal into a monophyllic multinary, e.g. ternary or quaternary digital signal includes a comparator and converter (Fig. 8) in which the input signal is compared with reference levels to give an indication of the range in which it lies and in which it is then operated on to give an analogue output signal which is applied via a delay to the input of the comparator/converter circuit. In the embodiment described for converting an analogue signal x at terminal 55 into a monophyllic ternary signal at terminal 54, the input signal is converted by a transformer 800 into two signals X and- X at 801, 802 which are fed via resistances 811, 821, 831, 841 of value R together with reference voltages + 1, - 1 from sources 803, 804 to amplifiers 815, 825, 835, 845. The reference voltages are fed via resistances 812, 822, 832, 842 of value 3R and resistances 813, 814, 823, 824 and 833, 834, 843, 844 in the feed back path of the amplifiers have values 1À5R and 4À5R respectively so that if (1) X # - a signal y = - 1À5 (X + 1/3) is fed to resistor 818; (2) X < 1/3 a signal y = -1À5 (X-1/3) is fed to resistor 828; (3) X # 1/3 a signal y = -4À5 (- X + 1/3) is fed to resistor 838 and (4) X < - 1/3 a signal y = - 4À5 (- X - 1/3) is fed to resistor 848. These signals are inverted by amplifier 805 so that a function as shown in Fig. 2 is generated i.e. if X = - 7/15, the output of the converter at terminal 56 is y = - 9/15. The amplifiers 835, 845 operate as a comparator, a positive output from the first indicating X > 1/3 and a positive output from the second indicating X<-1/3. From these two signals which are fed to a comparative detector 51 the range in which X lies is determined and the appropriate signal "-", "0", or " +" transmitted to terminal 54. The process is then repeated with the output from terminal 56 being used as the new input.

Title: Improvements in or relating to the manufacture of goods of rubber or similar material
IPC: C08J9/40
Filed: 1932-09-29
Abstract: The fire-resistance of sponge rubber and the like is increased by impregnating it with a fire-preventing agent, or a substance which yields a fire-preventing agent, deposited from a fluid medium. Examples of fire-preventing agents are ammonium salts (e.g. sulphate, phosphate or chloride), sodium phosphate, borax and selenium powder. A colloidal binding agent, e.g. casein, gelatin-glycerol or gelatin-glycol, may be added to the solution or dispersion of the fire-preventing agent.  An anti-oxidant may also be added.  In an example, sponge rubber is soaked in a solution of 100 parts of ammonium chloride, 6 parts of ethylene glycol, and 3 parts of glue in 300 parts of water to which 3 parts of an antioxidant has been added. The excess solution is squeezed out until the gain in weight is 120 per cent, and the sponge rubber is then dried.  In another example finely powdered selenium is dispersed in an evaporable liquid which is rubbed on the surface and into the pores of the sponge rubber so that some of the selenium is permanently retained.  Other examples are given. Specifications 332,525 and 332,526, [both in Class 70], are referred to.

[Class 7 (ii).] The radiator fan is driven by an electric motor F, the current to which is switched on and off by the expansion or contraction of a tubular thermal element 21 through which a portion of the cooling water circulates. The main circulating system comprises a tank T, pump P, cylinder jackets W, pipe C and radiator R and the thermal element, formed of German silver and brass, is connected by byepass tubing 20, 24, 25, and operates a lever 34, Fig. 3, through a rod 33. A valve 66 is thus lifted and pressure fluid-e.g. compressed air-flows from a tank 16 to actuate a spring-pressed diaphragm 52 and close switch contacts 45, 46 in the circuit of the motor F. A passage 77 allows the valve 66 to return to its seat when the element 22 contracts. Excessive expansion of the element 22 causes the lever 34 to lift a valve 70 and thus allow the pressure fluid to operate a whistle 75 or other alarm device.
