Abstract: 1410718 Surfactant slurries CONTINENTAL OIL CO 26 Feb 1973 [28 Feb 1972] 9355/73 Heading C5D The viscosity of aqueous anionic surfactant slurries is reduced by adding thereto dihexyl ether. The anionic surfactants comprise C 10  to C 16  alcohol sulphates, C 10  to C 16  alcohol ether sulphates containing 0À5 to 5 moles of ethylene oxide per mole of alcohol, alkylbenzene sulphonates containing 10 to 14 carbon atoms in the alkyl portion, C 12  to C 20  alkyl hydroxy sulphonates and C 12  to C 20  alkene sulphonates. The compositions preferably contain 0À2% to 5À0% by weight of dihexyl ether based on the weight of the slurry. The aqueous slurries contain 25% to 60% by weight of the anionic surfactant and are preferably those obtained during the preparation of the surfactants. Free oil (i.e. unreacted charge material and organic by-products) and inorganic and amine salts formed during neutralization of the acid surfactant may also be present.

Title: Padded triangular headed pins - which are cost and time saving in office use and have production yield. Are easy to remove from box
IPC: B43M15/00
Filed: 1973-03-14
Abstract: The pins, which are the subject of the insertion, have triangular shaped leads which do not become entangled in their box and which are very easy to separate and pick up.

Patent FR-2220739-A1 (FR)
Title: Fritted heat insulating material - made by dropping fused skin particles onto each other
IPC: C03B19/06
Filed: 1974-03-05
Abstract: The porous and flexible insulating material is made by fusing together of point contact particles which are fropped through a hot gas stream so that their surface only is fused and which settle on previously dropped particles the skin of which is still soft. The particles are pref. dropped counter currentwise through a downwards tapering shaft ensuring uniform dropping rates for both large and small particles. The material made by this process has larger pores than conventionally fritted material. This is because the particles are unable to pack down as the result of the sticktion on initial contact.

Title: Chopper and feeder for sugar cane - has overlapping cutter blades and bars on two vert. spaced cylindrical rotors
Inventor: SOULAT RENE
IPC: A01F12/40
Filed: 1974-08-23
Abstract: The chopper consists of two cylinder rotors (3, 4) turning around axes joined by a line inclined slightly forwards and upwards. The rotors are contra-rotating in order to draw in the crop and project it backwards after chopping. Rotor (4) has four circumferentially spaced bars welded along the length of the rotor. The two toros have equal diameters and cylinder (3) has a number of cutting blades (7) corresponding to the bars on rotor (4). The rotors are synchronised to turn at the same speed so that the unchamfered side of each blade slides down the rear wall of each bar with a small clearance. The paths followed by the tips of the bars and the blades are secant. The bars act as a type of elevator lifting the stems from the cutters to the chopper. The stems are cut cleanly with no shredding.

Title: Furnace for thermal cracking of hydrocarbons - with nonlinear reaction tubes
IPC: C10G9/20
Filed: 1975-02-04
Abstract: A pyrolysis furnace for the thermal cracking of hydrocarbons comprises a radiant zone within the walls of the furnace, which contains at least one reaction tube extending continuously through the radiant zone from its inlet end in a winding path. Furnaces contg. nonlinear reaction tubes can operate with lower mean tube-wall temps. than furnaces with straight tubes, and, for a given furnace height, a smaller no. of relatively large-bore tubes can be used, thus increasing the useful life of the tubes before removal of coke deposits becomes necessary. The tubes can be in the form of a helix, a double helix, a spiral, zigzag or a wave, and can be straight over part of their length. The radiant heat is pref. supplied by burners mounted on one end (pref. the top) of the furnace, or mounted on one side are pref. arranged vertically in the furnace. The pitch of the coil, etc., can be constant over the length of the tube or can be smaller at its inlet end than at its outlet end. The tubes are pref. circular in cross section.

Title: Electric vehicle with exchangeable battery - having coupling between trolley and battery and between battery and vehicle
IPC: B60K1/04
Filed: 1975-05-15
Abstract: The electric vehicle is fitted with a detachable battery which is held on the chassis frame of the vehicle on guide rails and which is secured by a coupling. The transport trolley is wheeled under the battery and the coupling is rotated by a control on the trolley. The coupling is disengaged between the vehicle and the battery while at the same time the same coupling links together the trolley and the battery. The system is fool-proof and ensures that the heavy battery is secured either on the vehicle or on the trolley. A rapid battery change is obtained.
Patent FR-2334087-A1 (FR)
Title: Fuse and charge for mortar shell - has sprung firing pin and primer drum with angled hole leading to detonator with foil seal
Inventor: CREPIN ROGER
IPC: F42C15/34
Filed: 1975-12-05
Abstract: The mortar shell has a nose cap with a spring loaded firing pin, fixed into the body of the shell. This is sealed into the base (2) containing the priming device. This primer is a drum with an angled hole (13) leading to a detonator (10) positioned above a wafer (12) which fires the lower charge (9). When the pin ignites fuse and detonator, this latter must rupture a foil seal (17) before it can ignite the lower charge. The seal prevents hot gases reaching the wafer and inadvertently igniting it when two shells are double fed, one on top of the other.
Patent FR-2346054-A1 (FR)
Title: Impact liq. atomiser incorporating nozzle and impact plate - produces flat sheet of very small high-energy particles
IPC: B05B1/26
Filed: 1976-04-02
