Title: Improvements in or relating to gyroscopic compasses
IPC: G01C19/38
Filed: 1939-08-04
Abstract: 583,786. Gyroscopic compasses. BROWN, S..G. Aug. 4, 1939, No. 22612. [Class 97 (iii)] The damping acceleration error, i.e. the small compass oscillation occurring after change of speed or course of the ship has been completed, is prevented by tilting the pendulous or gravitational element. The tilt is maintained constant so long as a particular speed exists, may be produced by hand, e.g. by adjusting the position of a weight, or automatically, and is such that it would, if acting alone, result in an oscillation equal and opposite to the error. As shown applied to a Brown compass, a small pendulum 5 is carried by a spindle 6 pivoted on the pendulous frame 1 carrying the gyroscope. The spindle 6 carries an armature 9 between polepieces 10, 11 variably energized by coils to produce a deflection of the pendulum 5 causing a tilting of the frame 1. The current may be supplied to the coils by a battery in a circuit including a resistance adjustable by hand, or a resistance or potentiometer adjusted automatically by the electric log of the ship. The pendulous element may, alternatively, be turned about its support axis by a motor. Specifications 22379/14, 124,529 and 124,533, [all in Class 97 (iii)], are referred to.

Patent GB-462823-A (GB)
Title: Improvements in and relating to the supply of electrical energy to varying loads, for example thermionic valve apparatus
IPC: H02M1/14
Filed: 1935-08-12
Abstract: 462,823. Impedance networks; valve circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd., and BLUMLEIN, A. D. Aug. 12, 1935, No. 22726. Addition to 421,546. [Classes 40 (iii) and 40 (v)] In television amplifiers and other apparatus in which the load varies, variations over a range of frequencies in the impedance of the source and its associated impedance elements, which would cause variations in the E.M.F. supplied, are prevented, as described in the parent Specification, to give the source a resultant resistive impedance when viewed from the load. According to this invention, more convenient values of impedance elements are obtained by using a filter constituted by a circuit resonant to an undesired frequency. The filter may consist of an L-type impedance network with a rejector circuit in the series arm and an acceptor circuit in the shunt branch or, when either the source or the load is floating, may comprise a bridge network having a rejector circuit in each series arm and diagonally connected shunt acceptor branches, Fig. 3 (not shown). Fig. 4 shows a filter between a rectifier and a load in which a resistance R1 is used to build out the impedance of the source so that the direct current regulation equals the input impedance of the filter. The arm L1, C1, C3 attenuates all ripple frequencies while L1, C1 is resonant to the main ripple frequency. The inductance L3 offers large impedance to the harmonics, the resonant frequency of the combination L3, L1, C1 being below the second harmonic. The branch R, L2, C2, C3 is arranged as described in the parent Specification to build out the filter to a resistance equal to R. The branch L4, C4, R4 comprises a further stage of smoothing' so arranged that C4, R4 is the mirror image of L4 and R4=R so that the whole apparatus viewed from the load simulates a pure resistance of value R. A dead load may be connected across the filter to prevent the current drawn from the source falling below such a predetermined value that the impedance rises to an excessive value. The Specification gives values of components for a 500 cycle supply.

A flange 4<11> may be screwed on the tube at the internal surface of the wall to tighten the joint. A ring 8 of bitumen-loaded hessian, of larger diameter than the ring 7 is then applied over the outer face of the flange 2, the joint being completed by the outer layer 6<1> of the wall waterproofing, and a collar 9 of bitumen-loaded hessian, all welded in position by heat. A skin wall 10 may be erected for the protection of the waterproofing on the structural wall 5, and an outer flange 4<1> may be screwed on the tube 1 to clamp the joint.

Title: Process for the manufacture of halogenated hydrocarbons
IPC: C25B9/19
Filed: 1964-06-03
Abstract: Halogenated hydrocarbons are formed by electrolysing a hydrogen halide and injecting a hydrocarbon or halogenated hydrocarbon in the vicinity of the anode, e.g. through hollow porous graphite. Hydrocarbons include lower aliphatic members up to hexanes, olefines, diolefines and aromatics, e.g. isobutylene, butadiene, and benzene. The halogenated hydrocarbon must include a replaceable H atom e.g. methylene chloride, and fluoromethanes.  A suitable apparatus consists of a graphite anode 3 having a central bore to which the hydrocarbon or halogenated hydrocarbon is admitted through pipe 11, and a cathode 5 separated from <PICT:1016485/C6-C7/1> the anode by a quartz fibre diaphragm 14.  HCl of 33% by weight concentration is admitted through pipe 16, passes through the diaphragm zone and leaves at pipe 17 together with some chlorinated products obtained, which are separated in a decantation bulb 7.  The main part of the volatile chlorinated product passes out at 19 and is fractionated. Hydrogen passes to an exit 18.  The temperature of the HCl is maintained at 40-100  DEG C., the temperature used and the current density controlling the nature of the product.  In examples the following products are obtained: ethyl chloride, di- and tri-chloroethane and higher chlorinated products, methylene chloride, chloroform, and carbon tetrachloride.

Title: Process for preparing finely divided calcium chloride
IPC: C01F11/30
Filed: 1964-06-04
Abstract: Finely divided CaCl2 is prepared by spray drying.  A substantially dry gas stream (e.g. air) at at least 400 DEG  F. is introduced into a drying chamber and an aqueous dispersion of CaCl2 is sprayed concurrently with the said stream.  The CaCl2 is removed along with the gas and separated.  The solution may contain 35-60 wt. per cent of CaCl2.  Granular CaCl2 may also be prepared by compacting the powder formed (e.g. between cylindrical rolls), at at least 200 DEG F., into a sheet.  The sheet may be broken into flake-like particles which are crushed to the desired particle size.  The particles may be classified by screening and particles outside the required range recycled, the smaller ones to the compacting step and the larger ones to the crusher.  The broken particles may be aged for at least 20 minutes before passing to the crusher.  NaCl may be mixed with CaCl2, either immediately prior to compacting or by using a mixed slurry of CaCl2 and NaCl for the initial drying.  Reaction conditions may be controlled to produce CaCl2 containing not more than 25% moisture where the initial solution contains at least 35% by weight of CaCl2. Examples relate to the application of the product of the process (when mixed with NaCl) for melting ice on roads.
