Title: Improvements in or connected with glass-moulding apparatus, chiefly for making pressed ware
IPC: C03B11/10
Filed: 1919-04-08
Abstract: 146,602. Daubenspeck, H. C., and Winder, S. E. April 8, 1919. Delivering molten metal; pressing; shearing.- Relates to a machine for making pressed glassware of the type in which the moulds are carried on a rotating table 59. According to the invention, the plunger is operated through an adjustable pneumatic cushioning-device. The molten metal flows continuously from a tank 15 and is separated into charges by pneumatically-operated water-cooled shears 33. Each charge drops into a mould 55 and is carried round beneath the plunger 100, which is carried by a short cylinder 116 mounted in a vertical slide. A piston 115 is reciprocated by the cam mechanism shown and, in rising, strikes the top of the cylinder 116 and lifts it. The interior of the cylinder 116 is connected by a pipe 120 with a chamber containing air at a constant pressure, and communication is controlled by a valve 121. The descent of the piston 115 forces down the cylinder 116 and with it the plunger 100, thus compressing the charge in the mould 55. By regulating the pressure in the cylinder 116, the pressure of the plunger 100 can be controlled. The finished article is subsequently ejected by a cam-operated ejector 66. The table 59 is formed with a thick rim 155 and is supported in the neighbourhood of the plunger 100 by adjustable rollers 156. The moulds 55 are mounted on plates 180 supported above the table 59 by distance-pieces 181 so as to reduce conduction of heat from the moulds 55 to the table 59. The machine is moved on its carriage 56 towards or away from the tank 15 by pneumatic power when desired.

Title: Humidity or dew point measuring apparatus
IPC: G01N25/70
Filed: 1947-04-02
Abstract: 641,555. Hydrostatic gauges. ILLINOIS TESTING LABORATORIES, Inc. April 2, 1947, No. 9029. Convention date, Sept. 30 1943. [Class 106 (ii)] [Also in Group XX] In an apparatus for measuring the dewpoint of gas samples wherein the pressure of the gas is successively lowered with resultant adiabatic cooling until a critical pressure is reached whereat no fog is formed on cooling (see Group XX), a pressure gauge is provided which enables a direct reading of the dew-point to be obtained. The gauge 133 comprises a tube 134 having a bore 134a containing, for example, mercury 140, the tube being curved around the periphery of a rotatable disc 135 which is mounted on a bracket 138 secured to a tube 139 which serves as the communication tube between the gas reservoir 81 and the tube 134 and also as the support for the complete assembly. The upper end of the tube 139 opens into a mercury trap 134b formed at the upper end of the tube 134, the arrangement being such that the bore 134a may be placed into communication with the tube 139 by tilting the instrument, without the mercury entering the tube 139, so that at the commencement of the test the pressure of the gas confined in the bore is that of the atmosphere. With such equal pressures on either side of the body of the mercury 140 the lower end of the mercury lies at the zero mark 143. The gas is then pumped into the reservoir to the desired maximum pressure and the rotatable dial 135, bearing a logarithmic scale of temperatures 136 is rotated until the graduation corresponding to the temperature of the gas in the reservoir is opposite the zero mark 143. The gas in the reservoir is then allowed to expand to atmospheric pressure in successive stages in a fog chamber, each stage being accompanied by a decrease in the pressure of the remaining gas and when the lowest pressure effective to produce fog is reached the position of the mercury corresponding to that lowest pressure indicates via a logarithmic pressurescale 136a the desired dew-point on the logarithmic temperature scale 136.

Title: Improvements in or relating to the production of gas expanded rubber
IPC: B29C67/24
Filed: 1937-03-31
Abstract: A mixture of carbon dioxide and nitrogen is obtained by burning with air a carbonaceous fuel such as the ordinary town gas supply and cooling the spent gases sufficiently to condense their water content. The carbon dioxide may be subsequently separated by liquefaction leaving nitrogen.  Preferably, the air supply is regulated to complete the combustion and leave no substantial quantity of oxygen in the gas mixture.  Any oxygen or any carbon monoxide may be removed from the gases in known manner.ALSO:In obtaining gas-expanded rubber material by a process described and claimed in the parent Specification in which a rubber dough in a container is subjected to an inert gas under high pressure and previously or simultaneously to a temperature sufficient to bring about a partial vulcanization and is thereafter subjected to heat and pressure to bring about its further expansion and the complete vulcanization, the inert gas employed is obtained by cooling the spent gases from the combustion of carbonaceous fuels in air, sufficient to condense their water content, and submitting the residual gas to sufficient pressure to separate the carbon dioxide by liquefaction. According to a modification, the gas mixture is introduced into the gassing chamber after the separation of carbon dioxide.  The fuel material may be the ordinary town gas supply and preferably the air supply is regulated to complete the combustion and leave no substantial quantity of oxygen in the gas mixture.  Any oxygen or carbon monoxide may be removed from the gases in known manner. However, appreciable quantities of air may be included without any effect on the rubber. Any of the well known soft or hard rubber or rubber like products such as isoprene polymers or olefine polysulphide resins may be used.

Title: Improvements in and relating to electric regulators
IPC: H02P9/24
Filed: 1926-04-08
Abstract: 250,932. British Thomson-Houston Co., Ltd., (Assignees of Thompson, L. li'.). April 14, 1925, [Convention date]. Regulation, automatic.-In a vibratory voltage or like regulator the vibrating arm 6, which has a spring 9 attached to one end, has its rate of vibration controlled by the combined action of the resilient arm 15 carrying the contact 8 and an adjustable spring 16 acting on its other end. Closing of contacts 7, 8 puts a coil 10 across the generator 3 whose voltage is to be regulated and if that voltage is sufficiently high the resistor 11 is open-circuited. As the load on the generator increases, the excitation should increase and the resistor should be short-circuited longer. To allow this, in the modification shown, a coil 20 across the exciter 2 is adapted to oppose the action of the coil 4. In other modifications, the coil 20 is energized by the generator field current or a further winding is added, aiding or opposing the action of the coil 4.

Title: Process for polymerising conjugated dienes
IPC: C08F236/04
Filed: 1962-03-12
Abstract: Polymers of conjugated dienes are made by polymerizing a diene alone, or in admixture with another hydrocarbon monomer, in the presence of a liquid organic diluent, and a catalyst comprising a cobalt and/or nickel compound, and at least one cyclic organic compound which is soluble in the diluent and contains non-conjugated double bonds in the ring structure, and is present in an amount not exceeding 500X10-4% by weight calculated on the diluent.  During the polymerization a small amount of water, or a compound of the type M(halogen)x where M=H, or a metal, and X = a whole number equal to the valency of M, may also be present.  Dienes mentioned are butadiene and isoprene. The butadiene may be employed as a stream mixed with butene-1, or butene-2.  The cobalt and/or nickel compound is preferably used as a catalyst in admixture with an organometallic compound such as an aluminium alkyl halide.  The cyclic compound may be bicyclo (2,2,1)-hepta-2, 5-diene. Compounds of the above type may be hydrochloric acid, tin chloride, or aluminium chloride. Exemplified catalyst are aluminium ethyl sesquichloride and the cobalt salt of 2-ethylhexane carboxylic acid, and aluminium diethyl chloride and CoCl2.AlCl3.  The polymerization may be terminated by the addition of ethanol in which the antioxidant 2, 21-methylene-bis-(4-methyl-6-tert.-butylphenol) is dissolved.  The polymers have almost exclusively a cis-1,4-configuration.

Abstract: 455,963. Variable - speed gearing ; gyroscopes. STERN, J. N., 49, Alstensgatan, Alsten, and LARSEN, H. B., 7, Kungsgatan, Amal, both in Sweden. March 26, 1935, No. 9470. [Class 80 (ii)] [See also Group XX] Relates to planet wheel gearing in which a carrier 5 rotates about the coaxial driving and driven shafts 1, 8 respectively and carries one or more gyroscopes 21 driven at a speed depending on the relative revolutions of carrier and sun-wheel shafts. According to the invention the gyroscopes, in addition to rotation about their own axis 22 and revolution about the sun-wheel shafts, are allowed to process, i.e. have a rotation about an axis arranged at an angle to the other two axes. Fig. 1 is a section along the line A-B, Fig. 2. The driving shaft 1 and driven shaft 8 have sun-wheels 2, 7 respectively and these gear with planets 3, 6, on a shaft 4 mounted in the planet carrier 5. The gyroscopes are rotated from either the driving or driven shafts through gearing 10, 20 separate from the planet carrier. Each gyroscope is mounted in a casing journalled at 23, 24 to the interior or exterior of the carrier 5. The gyroscope spindles have projections 25, Fig. 1, which enter slots in the hubs 28 so that the gyroscopes can tilt independently of the shafts, the amount of precession being limited by a resilient stop 27. The gyroscopes can be hollow bodies filled with mercury, the inertia, in spin, of which reduces shock on changes of speed. This effect may be varied by suitably shaping the hollow space.
