Title: Improvements in or relating to ribbon feed and reversing mechanism for typewriters
Inventor: BYERS EDWARD VICTOR
IPC: B41J33/516
Filed: 1968-12-20
Abstract: 1293538 Ink-ribbon mechanisms E V BYERS 16 Dec 1969 [20 Dec 1968] 60540/68 Heading B6F Automatic ribbon reversing.-The drive from a carriage movement rotating a shaft 10 is transmitted alternatively to ribbon spool ratchet wheels 17, 18 by pawl carrying bars 25, 26 in accordance with the position of a lug 44 engaging alternative lands 48 of a disc 47. This effects coupling of the bars 35, 36 alternately to the ratchet wheels 17, 18. The bars 25, 26 each have two pawls 27 or 29 which are biased towards the ratchet wheels 18, 17. Alternatively one bar is disconnected from its ratchet by the bifurcated ends of bars 35, 36. These operate, one to disconnect the ratchet and pawls and the other to connect them when tension in the ribbon does not allow a multilobe cam 19 to oscillate the pawl arms, but instead rotate the lug 43 and move the bars 35, 36.

Title: Combined pressure relief and vacuum relief valve
IPC: F15B21/047
Filed: 1971-12-30
Abstract: 1377509 Fluid pressure servomotor systems LAMBORGHINI OLEODINAMICA SpA 30 Dec 1971 [30 Dec 1970] 60760/71 Heading G3P [Also in Division F2] A combined pressure relief and vacuum relief valve comprises a main valve member 32 controlling a passage 22 between inlet 4 and outlet 5, and a pilot valve 29 also controlling communication between the inlet and the outlet and to the chamber 34 formed by the valve housing and valve member 32. Should the pressure in inlet 4 rise above a predetermined value, the pilot valve opens to admit pressure fluid to chamber 34 which opens the main valve member against a spring 47. Should the pressure in inlet 4 drop below atmospheric pressure, the force on the main valve member by virtue of the pressure in chamber 34 is sufficient to overcome the combined effect of the spring 47 and the reduced inlet pressure acting on the valve member 32.

Title: Feed device for pilger rolling mill
IPC: B21B21/04
Filed: 1969-12-29
Abstract: 1275820 Rolling tubes INNOCENTI SOC GENERALE PER L'INDUSTRIA METALLURGICA E MECCANICA 29 Dec 1969 [8 Jan 1969] 63110/69 Heading B3M A feed device for a pilger rolling mill includes a pneumatic piston 1 coupled to a support 5 for a tube blank 6, the blank 6 being fed to the right by the rolls of the mill and being returned to the left by the piston. A head 1a of the piston slides in a cylinder 9, and is arranged to compress 7 air in the cylinder at a variable rate. As the piston moves to the right, air in the cylinder passes, through vents in a hollow air tube 7 in the cylinder, to a port 12, until the piston covers the vents. At this stage the air remaining in the cylinder is compressed and acts as a buffer both to stop movement of the piston and to accelerate it in the opposite direction. Air supplied to the port 12 passes through the vents to maintain the acceleration. The characteristics of the device can be varied by adjusting the axial positions of the tube 7 and of an end stop 8 for the cylinder. An hydraulic brake 13 is provided, and a bush 3 for rotating a helically grooved port 2 of piston 1 as it reciprocates.

[Also in Group XXV] A method of forming a lapped water-tight envelope about a metal pipe &c. 6, from a composite tape comprising a layer of unvulcanised rubber 5 and a carrier layer 4, the latter having a high modulus of elasticity compared with the former, comprises separating the component layers 4, 5, as they leave the supply roll 3 and separately lapping them helically on to the pipe 6, the layer 5 forming the outer part of the envelope, running on to the pipe at a point in advance of the other, as by arranging a guide 7 therefor at a small angle to the axis of the roll 3, the speed of travel of the pipe in the direction Y, through the lapping head, relative to the speed of revolution in the direction X of the roll 3 about the pipe, being such that successive turns of the layer 5 overlap and are in contact with each other. If a double-walled envelope is required about the pipe; after the first composite tape has been applied, as above, a second one is applied thereover with the rubber layer on the inside. In this latter method, the ingredients of the rubber layers are arranged to be complementary. Specification 693,460 is referred to.

Title: Process and installation for the separation of gases by gas diffusion
IPC: B01D53/22
Filed: 1978-09-26
Abstract: In a process for the separation of a mixture of gases in one or more diffusion stages (D1, D2....Dn), each stage is fed at an optimum flow rate by means of regulators (E, G1, G2.... Gn), taking into account the concentration of the lightest gas in the charge (a) and the diffusion rate of this gas, so that the total amount of the lightest gas passes into the diffused phase. The undiffused phase (c) at each stage is extracted without recycling to an upstream stage. The regulators (G1, G2...Gn) incorporate analysers to detect the presence of any of the lightest gas in the undiffused phase (c). There may be recycle of diffused phase in one or more stages and a stage may comprise a plurality of diffusers arranged in parallel. <IMAGE>

Title: Separating liquids
IPC: C02F1/40
Filed: 1979-04-30
Abstract: To remove a contaminating layer of a liquid of lower specific gravity (e.g. oil) floating on a liquid of higher specific gravity (e.g. sewage), the liquids are forced to flow along a settling tank towards a collector (5) whose open bottom is disposed well below the boundary (10) between the liquids. The top of the collector (5) is sealed to an inclined weir (3) dipping just below the boundary (10) so that the contaminating layer ascends the weir, assisted by air jets from nozzles 4, and flows into the collector (5). A discharge duct (6) is disposed in the collector (5) with an adjustable inlet arranged in a plane higher than the liquid-liquid boundary (10) but lower than the surface (14) of the contaminating liquid in the collector (5). The collector and nozzles are supported by floats 2, and duct 6 is connected to tank outlet 8 by a flexible tube 7. <IMAGE>
