Title: Continuous isopropanol prepn - by hydrating propylene using cation exchange resin catalyst and gradually increasing reaction
IPC: C07C29/04
Filed: 1973-03-23
Abstract: Continuous prodn. of lower alcohols, esp. isopropanol, is effected by catalytic hydration of lower olefins, esp. propylene, in the presence of a strongly acidic opt. cross-linked cation exchange resin as catalyst esp. in a column contg. a fixed bed of the catalyst, through which the liquid or gaseous reactants flow downwards at 120-180 degrees C, 60-200 atm. and a column cross-sectional load of 1-40 esp. 5-25 moles water per cm2. at.hr., the molar ratio water : olefin being 1-30 : 1 esp. 10-20 : 1. The reaction temp. is increased gradually in such a manner that the catalyst efficiency (in moles alcohol per l. catalyst per hr.) lies always above a predefined minimum value within its useful life. Catalyst efficiency remains always above an economically acceptable value during the useful life of the catalyst. The alcohol concn. in the reaction pdt. remains approx. constant, thus facilitating recovery.

Title: Continuous conveyor system for oranges - has pad containing granulated particles and carrying goods along horizontal path between loaders and ejectors
IPC: B65B25/04
Filed: 1975-09-12
Abstract: The conveyor is for the transportation of sensitive goods, esp. oranges, between a supply station, where the goods are supplied free falling, to an output station. The conveyor has a continuous row of support pads. Each pad has a cover contg. displaceable granulated particles. Before arrival at the supply station, the particles in each pad are subjd. to a displacement force, so that the pad is outwardly arched. The displacement of the particles due to the force of the falling object is utilized to accommodate and reduce the active impulse forces, and to form a seat for the object during movement towards the output station. To form the outward movement, the pads are turned upside down, when they return from the output-to the supply station via the lower section of the conveyor.

Title: Vertically split sail boat mast - forms venturi gap which points towards leeward side of sail with vertically pivoted valve flap carrying sail
IPC: B63B15/00
Filed: 1976-05-14
Abstract: The mast for a sailing vessel consists of two vertical halves (1, 2) connected to one another (4, 5) and symmetrically arranged on either side of the vertical plane of symmetry (3).

One vertical edge of the member projects outside the mast at the side of the sail which is secured to this edge. The other edge is within the gap and can swivel into contact with one or the other surface (6 or 7) whereby the valve forms a venturi with the opposite surface (7 or 6) pointing towards the leeward side of the sail.

Title: Flexible thin walled rollers prodn. for flat or deep printing - reducing storage and transportation costs and minimising risk of impact damage
IPC: B41C1/18
Filed: 1977-08-03
Abstract: The rollers are fabricated by coating a passive master roller with a 50-500 mu layer of Ni, removing the Ni sleeve from the master roller and then electrolytically depositing a Cu coating. The Cu coating is then machined to the required thickness (>=5 mu), and a layer of Cr is deposited. After removal of the Ni jacket from the master roller, the jacket is pref. filled with an air or water bag to lend it some structural stability for the subsequent operation. A flat print roller pref. has a Ni layer of 200-300 mu a Cu layer of 5-10 mu and a Cr layer of 0.5-3 mu. A deep print roller pref. has a Ni layer of 100-200 mu, a Cu layer of 50-500 mu and a Cr layer of 3-25 mu. The print pattern on a deep print roller can be replaced by machining the Cu to below the etching depth, depositing a new Cu layer, etching this as required and then Cr plating. The flexible, thin walled rollers are cheap to store and transport, whilst the risk of impact damage is minimised.

Title: Coke oven battery regenerator chamber - has stacked bricks moved in or out by carriage with lift platform movable in duct below chamber
IPC: C10B29/00
Filed: 1980-11-12
Abstract: The mechanism is intended for moving bricks (3) stacked on supporting bricks (4) out of and into the regenerative heating chamber (walls 1,2) of a coke oven battery contg. a number of coke ovens. It comprises a carriage (13) which is movable (wheels 15) in the gas duct below the chamber and the supporting bricks (4) and is provided with a lift platform (16) raisable by hydraulic cylinders (19). The length of this platform may be a little less than the length of four, or pref. of six, stacked bricks (3) and the platform may be provided with a vertical plate (not shown) at one end to provide location relative to a brick stack. Used for moving stacked bricks into and from regenerative heating chamber in coke oven battery. Lifting the brick stakcs together with the supporting bricks (4) avoids the need for special supporting bricks as previously used which provide unsatisfactory support for the stack and make handling more difficult. The platform provides stable support for the stack, avoids contact of the stack with the chamber walls during transfer and enables the assembly of stacked bricks to be transferred in parts, e.g. columns of four or six brick lengths, thus limiting the space required for handling outside the chamber.

Filed: 1983-06-27
Abstract: The lift landing door frame arrangement contains horizontally adjustable lateral caulking or sealing elements arranged at uprights of the door frame and a vertically adjustable top caulking or sealing element associated with the topside of the door frame. To avoid retouching due to the caulking elements at the time of placement of the lift landing door frame arrangement and to avoid the formation of gaps in the door frame after placement, each lateral caulking element comprises a rectangular sheet metal panel of a length which exceeds the height of the door frame. Each lateral caulking element engages with and is fixed to the interior of the related upright. Each lateral caulking element is also guided for simultaneous vertical and horizontal adjustment at a guide plate carried by the related upright. The vertically adjustable top caulking element is constituted by a U-shaped sheet metal strap which is disposed astride the front parts of the door frame and is laterally guided thereat. This lift landing door frame arrangement is particularly suitable in cases in which the lift or elevator shaft does not include lateral masonry returns at the landing openings.
