Abstract: 1392782 Jet propulsion engines TEXACO DEVELOPMENT CORP 31 Jan 1973 4878/73 Heading F1J The invention relates to a reaction propulsion engine suitable for operation at hypersonic speeds in which a heat exchanger is disposed adjacent the air inlet whereby the inlet air is cooled before compression in a turbine driven compressor, and fuel is pre-heated, the pre-heated fuel then flowing in part through a mixer to the turbine and in part to a regenerative heat exchanger disposed in a combustion chamber, the heated fuel then passing to the mixer where it mixes with the first part to flow to the turbine. The combustion gases are discharged through a propulsion nozzle. The fuel passes from the heat exchanger to a turbine by-pass valve from which a first portion passes to a turbine temperature modulating valve from which a first part flows to a mixer and a second part flows to a regenerative heat exchanger disposed in the combustion chamber, this second part after heating passing to the mixer from which the fuel passes to the turbine. The fuel after expansion in the turbine passes to the combustion chamber where it is burned together with air from the air compressor. The gases from the combustion chamber discharge through a propulsion nozzle. A second portion of fuel from the heat exchanger passes direct to the combustion chamber. The fuel may be hydrogen or hydrogen-bearing compounds such as ammonia, methyl alcohol, ethylene glycol and cyclohexane.
Patent GB-1304282-A (GB)
IPC: H01L35/30
Filed: 1970-02-02
Abstract: 1304282 Semi-conductor devices THERMOBAUELEMENT AG 2 Feb 1970 [3 Feb 1969] 4880/70 Heading H1K A heat-absorbing/yielding mass of a material at least one form of which is a non-metallic crystalline solid, preferably ionic, has a phase transition at a temperature close to the optimum working temperature of a device with which the mass is in heat-exchange relationship. The material may be a (hydrated) inorganic salt, metal acetate, or metal hydroxide and the phase change may be between solid and liquid or between polymorphous solid phases. The low temperature phase is chosen to be of low thermal conductivity so that the device rapidly heats to its desired operating temperature and heat is only then used to further propagate the phase transition. The material may be housed in a plastics container. When the high temperature phase would be a mobile liquid powdered silica or magnesium oxide may be added to increase its viscosity and cut down convection currents. Internal finning may be used to extract heat from the material and the container may also be externally finned. An elongate part in communication with the main container may hold material which remains in the low temperature phase and serves to initiate the reverse transition. Diodes, transistors, and thyristors may be thermostatted in this way. The mass may also be placed at the heat-yielding end of a Peltier unit used to cool a semi-conductor element. In a variant the mass is placed at one end of a Peltier unit which is to extract heat from or supply heat to a space, in which case heat may be fed from the mass to the space by turning off or reversing the current flow in the Peltier unit.

Patent GB-257503-A (GB)
Title: Improvements in reservoir pens
IPC: B43K5/16
Filed: 1926-02-27
Abstract: 257,503. Kovacs, T. Feb. 27, 1926. Nib-retracting reservoir pens; facilitating filling; air and ink supply arrangements.-In nibretracting fountain pen of the type in which a nib-securing ring is adapted to prevent leakage from the barrel when the nib is retracted, the air and ink passages around and through the ring are arranged so that the reservoir can be filled from the upper end when the nib is partly or wholly retracted. The one-piece barrel G is formed at its front end with an internal shoulder B with which the nib-securing ring D co-operates to prevent leakage during writing, and with another shoulder E which divides the interior of the barrel into the reservoir proper F and a small outer chamber C. The chamber C is so short that the point of the nib projects slightly even when the nib is fully retracted. The ring D and shoulder E co-operate to prevent leakage from the barrel when the nib is retracted- A slight clearance is left between the shoulder E and ring D to permit the passage of ink from the chamber C into the reservoir F but not sufficiently large to allow the passage of air when the space contains ink. The air and ink channels J, K respectively in the bar H extend a sufficient distance to prevent the accumulation of ink near the ring D during filling. The channel J extends as far as the helically-slotted member N when the nib is retracted, but the channel K extends as far as the member N when the nib is projected so as to facilitate the steady flow of ink from or into the cavities in the member N. In order to permit the escape of air from the cavities during retraction of the nib, there is provided on the. opposite side of the bar H an air channel L extending from the end of the bar to a point beyond the member N when the nib is retracted. The helical slot M in the member N is provided with a reversely-directed extension M<1> at the front end to prevent rearward movement of the nib during writing, and also to impart a short forward movement to the nib before retraction so that any ink contained in the channels J, K is sucked back and prevented from spurting out of the barrel. The slot M is of coarse pitch so that less than one turn is necessary to project or retract the nib. The member N is rotated by means of a head R formed with an annular groove in which is secured a pin adapted to engage with a pin T fast in the closure member 0 of the barrel to limit the rotation of the retracting-mechanism.

Title: Improvements in or relating to waterproofing emulsions and to methods of preparing same
IPC: C04B26/04
Filed: 1939-04-21
Abstract: 528,308. Light-weight felted fibrous boards. JACKSON, L. MELLERISH-. (Bakelite Building Products Co., Inc.). April 21, 1939, No. 5853/40. Divided out of 527,857, [Group V]. [Class 96] [Also in Group III] An emulsion is prepared by high speed agitation of a water repellent substance substantially solid at atmospheric temperature with at least 80 per cent. of an aqueous soap solution having a concentration of less than 12.5 per cent. sufficiently rigorously to produce particles in the disperse phase having an average size of 2-25 microns which on dilution of the primary emulsion are transformed into mobile groups of particles having adherent properties. In examples: (1) paraffin wax is dispersed in water by means of sodium stearate in a 5 gallon mixer having a half-inch circular blade with a corrugated facing ; (2) melted rosin containing some turpentine is run into a solution of potassium stearate and dispersed by means of high speed agitation ; (3) chlorinated naphthalene, Chinese wax and a mixture of Egyptian asphalt and paraffin wax are dispersed by means of sodium stearate. Any natural or synthetic resin, estergum or wax may be used as the water repellent substance. Carnauba wax, shellac and beeswax are mentioned and solvents such as benzine, toluene, alcohol or petroleum may be used when necessary, but the latter should be substantially removed before the completion of the formation of the secondary emulsion by dilution. By the addition of small quantities of the secondary emulsions to the composite materials such as are described in Specification 527,857, [Group V], the moisture absorption properties of the latter are reduced. The following examples of this application of the emulsions are given:-(6) an emulsion prepared as in example 1 is added to a non-settling pulp of asbestos and water ; Portland cement is then incorporated and the mixture run upon a screen, dewatered and subjected to pressure. When cured and dried the resulting moulded product is suitable as a lightweight, fireproof, wall panel material: (7) a product, of "honeycombed structure" is obtained using "news-stock" in place of the asbestos in the previous example.
