Title: Spectacle lens data calculator - determines thickness of lens blank
IPC: G06G1/00
Filed: 1973-05-07
Abstract: A linear or circular slide rule is for calculating the optimum thickness of a lens blank so that after polishing and grinding to the required optical characteristics the final lens is neither too thick and heavy nor too thin and fragile. Various scales allow for entry of focal length, front and rear surface curvatures for different lens diameters, and correction factors for lens thickness, and also enable a direct reading of the thickness of the starting blank to be obtained.

Title: Transport conveyor with enclosed belt - for high viscosity material, e.g. wet concrete
IPC: B65G15/08
Filed: 1973-06-22
Abstract: Conveyor belt of reinforced rubber with diagonal pattern is gradually bent from a flat belt into a pipe through guide-rollers that are fitted in a certain pattern. Once formed as a tube, the high viscosity substance, e.g. concrete is kept in place because the diagonal ridges on the belt are now inside and form a screwed patter. In this way the substance can be elevated under virtually any angle. It can also be used fo loose substance like gravel.

Title: Sepn. of carbon dioxide from natural gas - using double distillation with second column at lower pressure
Inventor: GAZZI LUIGI
IPC: C07C7/04
Filed: 1976-05-19
Abstract: Process for separating CO2 from natural gas and other mixtures with CH4 uses distillation with two columns or column sections in which the press. in the first column is higher than in the second with distillate from the first column being fed to the second column and the base product from the second column being returned to the first. The first column is operated at a press. of >48 atm., while the second column is operated at 45.8 atm. but higher than the press. at which liquid present in the column exist as a solid phase, a liquid phase being fed to it. The condenser for the higher pressure column can be maintained at a temp. which is higher than the temp. in the reboiler of the second column and the heat released by condensation is directly reused in the reboiler which then forms a single unit with the condenser. Used to remove CO2 from natural gas and other methane mixtures where the CO2 content is >=20 to 30 mole %. The system gives very high purity fractions by using the principle that the critical press. for CO2 is 48 atm. while that for CH4 is below this. This gives a max. purity for CH4 at this presS. of 48.5 mol.%. This problem is overcome by operating the process of two pressure so that high purity CH4 is obtained at a lower press.

Splint and fixing devices can be cut out from metal sheet of varying characteristics, being then coated by the portions forming the teeth.

Title: Horizontal continuous ferrous metal casting - where molten metal is scrubbed with inert gas before entering mould
Inventor: SLADKOSHTEEV V T
IPC: B22D11/10
Filed: 1976-12-17
Abstract: Horizontal continuous casting process, where a stream of molten metal falls stepwise towards a channel leading to the mould. In a first step (a) the melt is scrubbed with gas from a surface which has a height 300 mm above the top of the channel leading to the mould. In (a), the gas is pref. blown upwards into a region of the melt where a vortex is formed. Pref. the melt flows downwards into a vessel with a stepped base; baffle plates are located above the higher portion of the base to create a scrubbing zone fed with gas, and a settling zone in which the melt flows downwards to a channel leading to a chilled mould. Used esp. for the continuous casting of ferrous metals and their alloys. The melt is scrubbed with inert gas, e.g. argon, to remove air, gases and non-metallic inclusions, thus improving the physical and mechanical properties of the casting.

Title: Sheet metal supply bin with height adjustable false bottom - is used to supply press operator with plates and obviates need to reach into empty bin
IPC: B21D43/20
Filed: 1977-01-03
Abstract: The bin (1) has a height-adjustable false bottom (4) and may be deployed at machining-stations, e.g. contg. pieces of sheet metal, (5) in the near vicinity of a press-operator. The false bottom (4) may be lifted by degrees by operating a push-button (24) or a foot pedal, and eliminates the need for the operator to reach into the bin when nearly empty. The bin is elevated by motors (6) which are controlled by the push-button (24), and the motors may be of the reduction type. The motors rotate horizontal screws (8) which in turn modify the configuration of scissor frames (19, 20) supporting the false bottom (4). The frames (19, 20) may be 'X' shaped with horizontal pins (21) through the node and a worm (15, 16) a appended to each foot. Rotation of the screws (8) causes the worms (15, 16) to move towards one another and raise the false bottom (4) or vice versa.
