Abstract: 1,182,183. Incandescent lamps. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RESZVENYTARSASAG. 8 May, 1967, No. 21372/67. Heading H1F. Sealing off the exhaust tube of the envelope of an incandescent lamp containing a gas filling at an above-atmospheric pressure is effected by heated jaws, the closure of which initiates the restarting of an automatic sealing unit which is switched off for the duration of the sealing step by an electric control device. The sealing unit is controlled by a motor which drives a shaft carrying cams for effecting various steps in the cycle of operations, the motor circuit itself being opened by a cam-operated switch timed to operate at the same time as the jaws engage the neck of the envelope, and closed again by the closure of a pair of contacts on the sealing jaws when the sealing operation is completed. The jaws are heated by current which for the first period of the heating passes through a resistor which at a later stage is short-circuited to speed-up the heating. During this stage an applicator consisting of a brush 22, reciprocated by a rack-and-pinion mechanism 21 between rollers 23 containing colloidal graphite and the inside surfaces of the jaws l 1 , l 2 , transfers the graphite to the jaws which are then advanced by a cam 13 and caused to close on the filling tube of the lamp 16 by a cam 20.

Title: Control apparatus for the stabilization of ships
Inventor: BELL JOHN
IPC: G01C21/18
Filed: 1952-08-26
Abstract: 774,483. Automatic control systems. MUIRHEAD & CO., Ltd. Aug. 14, 1953 [Aug. 26, 1952], No. 21391/52. Class 38 (4). In a system for automatically stabilizing a ship, a signal dependent on roll acceleration is combined with a signal dependent on roll angle so that the former signal predominates over the latter under conditions of simple harmonic motion, the resultant signal being utilized to advance in phase by not more than 30 degrees a signal, dependent on roll velocity, which is utilized to stabilize the ship. In Fig. 4 a voltage dependent on angle of roll of a ship, produced by a gyro-vertical 5 operating a potentiometer, is added to a voltage dependent on roll acceleration produced by a roll velocity gyro 6 operating a generator 7. The resultant voltage, which is arranged to have the acceleration voltage predominating when the ship is undergoing simple harmonic motion, is applied to a magnetic amplifier 8 the output of which is applied to a winding of a variable inductive device 9 operated by roll velocity gyro 6. Inductive device 9 thus produces an output, dependent on angle of roll and its first and second derivatives, which is utilized to control a servo system (not shown) stabilizing the ship. In a modification, three variable inductive devices, respectively operated by gyro systems responsive to angle of roll, roll velocity and roll acceleration, are arranged to produce a resultant voltage. Gyro systems involving springs and dashpots, eddy current brakes or two restrained gyros mounted on a pivoted platform to produce a movement dependent on roll acceleration are described. Alternatively roll acceleration response may be produced by mass inertia. Relative adjustment of the magnitude of the components of control by varying the gain of magnetic or electronic amplifiers is referred to. Specification 581,776 is referred to.

Title: A process for isomerizing dialkyl benzenes in the liquid phase
IPC: C07C5/27
Filed: 1955-07-28
Abstract: Diisopropyl benzene or a mixture of diisopropyl benzene isomers is isomerized by passing in the liquid phase over an aluminium silicate catalyst at 100-300 DEG  C.  The catalyst may consist of silicates formed from silica and smaller amounts of alumina and of oxides of other metals such as iron, zirconium, magnesium, calcium, sodium and potassium, and of oxides of hydrogen, carbon and sulphur.  The catalyst may consist of 85-90 per cent SiO2 and 15-10 per cent Al2O3. The catalyst preferably contains less than 3.5 per cent of water. The process may be carried out at a pressure of 10-80 atm. and preferably less than 5 parts by volume of liquid reactants are passed through each part of the reaction zone per hour.  The process may be carried out by alkylating benzene, cumene or mixtures thereof with propene, distilling from the reaction mixture the fraction containing o- and m-diisopropyl benzene and isomerizing this fraction to obtain benzene, cumene, o-, m- and p-diisopropyl benzenes and higher alkylates.  The o-isomer is practically completely converted and the m-and p-isomers can be separated by distillation.  The benzene and cumene formed may be recycled to the alkylation process; the higher alkylates may either be dealkylated or trans-alkylated with benzene and cumene and the p-isomer separated from the diisopropyl benzenes formed in each case.  Specifications 749,186 and 749,187 are referred to.

A mill for disintegrating, sifting and separating materials comprises a tapered grinding ring 6, Fig. 1, the largest diameter of which faces the side at which the grinding stock is centrally fed into the mill, a rotor 4 arranged within the ring and having beating elements 5 shaped to match the grinding face of the ring, a classifying chamber 9 defined by the rotor 4 and a screen 7 and the inner edges 8 of the beating elements, and an annular slot 25 provided in front of the largest diameter of the grinding ring and communicating with an annular chamber 10, the cross-section of the slot being variable by a screen. The material is fed to the machine through a hopper 3 to a chamber 13 where it is ground in a zone 18 by the beating elements 5 and the ring 6. The coarser material, such as husks and shells of kernels in the case of cereals, tends to flow towards the largest diameter part of the ring and if the slot 25 is open, it is discharged through chamber 10. If the slot is closed by axial movement of the screen 11, the coarse material is crushed to a degree permitting it to be moved by the air flow in the mill. The elements are mounted on the rotor at a slight angle and the rotor is axially displaceable to vary the distance between the elements and ring. The radial distance between the ring 6 and outer edge of the elements is less than the radial distance between the outer edges of the elements and the circumference of the rotor. A grid 17, Figs. 1 and 2, is secured to the screen 7 and directs the finely crushed material in the classifying chamber 9 through an aperture 19 into a discharge channel 14 ; any coarse particles in chamber 9 are forced by the spiral air flow in the chamber back into the grinding zone. In another embodiment, the rotor 4 has pins extending into the chamber 13. The beating elements need not extend from the rotor towards the input side of the mill and a flange may be mounted on the circumference of the rotor to permit the grinding zone to be adjusted. In a further embodiment, the face of the grinding ring is provided with axially-extending grooves. In yet another embodiment, the grid 17 is formed as a vane-type wheel rotatable independently of the rotor to pass finely crushed material to the discharge shoot and to return coarse material to the grinding zone.
