Title: Para-(octyl or tert-butyl) phenol prodn. - from phenol and diisobutylene over cation exchanger pref. with anhydrous catalyst
IPC: C07C37/14
Filed: 1973-05-08
Abstract: Para-octylphenol and para-tert-butylphenol are prepd. by passing a warm mixt. of phenol and diisobutylene through a fixed bed catalyst of solid cation exchange resin in the acid form carrying sulphonic gps. in the anhydrous or 10-20 wt.% hydrated form; distilling the reaction prod. without pretreatment to separate and recycle the unreacted starting materials and to selectively obt. one of the prods. Para-octylphenol is obtd. with a reaction temp. of 85-110 degrees C whilst para-tert-butylphenol is obtd. at 120-130 degrees C. When a hydrated catalyst is employed the mixt. of reactants may be hydrated to the amt. of 1-2 wt.% (based on the wt. of phenol). The cation exchange resin is pref. macroporous and in the form of 0.2-0.5 mm dia. balls. It may be sulphonated polystyrene cross-linked with divinylbenzene. A catalyst hydrated with 10-15 wt.% water is pref. used in para-octylphenol prepn. at 100-105 degrees C and an anhydrous catalyst at 125-130 degrees C is pref. used to prepare para-tert-butylphenol. The alkylphenols obtd. are starting materials for the prodn. of phenoplasts. The process is non-polluting, uses a cheap catalyst and recycling of starting materials improves yields.

Title: Tube flow cut off device for use during fires - tube is crushed by pair of jaws held parallel by linkage
IPC: F16L55/10
Filed: 1973-06-04
Abstract: The device has an upper fixed jaw carrying a bolt over which screws a moving jaw whose gripping surface is parallel to the gripping surface of the first jaw. A pair of links cross in the form of an X and are each connected to the rear end of one of the jaws; their forward ends carrying pins sliding in slots which are parallel to the gripping surfaces. A handle is carried by the fixed jaw and by turning the bolt the jaws are attracted to each other to grip and squash the tube and thus cut off the fluid flow. The links ensure that throughout their movement the gripping surfaces are maintained parallel.

Title: Filter for gas from aluminium electrolyser - electrostatic precipitator removes heavy metals from and alumina then absorbs fluorine cpds
IPC: C25C3/22
Filed: 1973-09-06
Abstract: A filter appts. for gases evolved from an electrolytic cell used for making Al consists of an electrostatic precipitator, in which the gas stays for 0.1 - 1.0 sec., with an arrangement for injecting alumina into the gas flow immediately it leaves the precipitator, the alumina being esp. intended to remove F cpds., while the electrostatic precipitator removes mainly heavy metals, partic. Fe cpds., with possibly some tar from the baked C electrodes, though a much longer stay in the precipitator would be needed for complete tar removal. The gases and alumina pass to a bag filter, while the alumina with absorbed F cpds. is sent to the electrolytic cell. In this way the presence of Fe cpds. in the alumina, with consequently adverse affect on aluminium quality, is avoided.

Title: Quayside container handling gear - has stabilising cables and intermediate guide frame for load
IPC: B66C13/06
Filed: 1973-12-11
Abstract: A frame which can travel on the quayside, alongside the ship, has a wheeled carriage travelling on rails cantilevered over the ship's hold and carrying a winch for cables raising and lowering containers inside the hold.

Title: Porcelain made from artificial ingredients - shows improved strength and translucency
IPC: C04B33/13
Filed: 1975-02-19
Abstract: Porcelains are obtd. by firing a raw paste prepd. from Al2O3 quartz, alkali(ne earth) oxides and/or cpds., which on firing give these oxides, or e.g. alumino silicate glass compsns.

Title: Navigational method and related equipment - uses sine-cosine potentiometer and makes incremental positional coordinate changes according to mathematical formulae
IPC: G01C21/14
Filed: 1975-03-05
Abstract: The method of position determination involves making constant increments dx, dy in the known coordinates X deg. and Y deg. of latitude and longitude, where dx=Vr cos Cr/dt and dy= Vr sin Cr/dt where Vr is the actual velocity of the moving vehicle Cr is the true heading, and dt is the time interval between two successive increments. The instrument for putting this technique into practise includes a sine-cosine potentiometer (O) supplied by voltages - Va, + Va which prepresent the apparent velocity. The potentiometer provides the components Vr cos Cr and Vr sin Cr. The actual velocity Vr is determined from the apparent velocity (Va) and the drift (d) while the true heading Cr is determined from the magnetic heading (Cm) and the declination (D).
