Abstract: 647,719. Electrolytic production of chlorates. PENNSYLVANIA SALT MANUFACTURING CO. May 20, 1947, No. 13591. Convention date, Aug. 12, 1946. Addition to 644,318. [Class 41] A process for the production of chlorates as described and claimed in the parent Specification is characterized in that the electrolyte liquor is kept for at least five minutes after first contacting it with chlorine before introducing it into the cell. The process may be carried out in apparatus comprising electrolytic cells 5 into which the aqueous solution of chloride is introduced as electrolyte, and means for acidifying the solution such as a cylindrical shaped tower 1 having an inlet 4 at the top for the electrolyte from the cell and near its base an inlet 2 for the chloride and an outlet 3 for the treated electrolyte which is fed again to the cell. The electrolyte output from the cells is fed partly to the apparatus 8 for chlorate separation and partly to a storage tank 7 which also receives the liquor from the chlorate separation tank 8 after the addition thereto in tank 9 of the chloride. From the storage tank 7 the liquor is pumped by pump 10 via conduit 4 to the top of the tower 1 which is so designed as to maintain a depth of electrolyte therein through which the chlorine is passed, the treated electrolyte being withdrawn through conduit 3 from the bottom of the tower. Overflow line 11 returns excess electrolyte from the tower 1 to the storage tank 7.

Title: A thermally insulated metal pipe
Inventor: KAUFER HELMUT
IPC: F16L59/14
Filed: 1969-03-14
Abstract: 1,236,314. Thermally insulated pipe. VEREINIGTE DEUTSCHE METALLWERKE A.G. 14 March, 1969 [15 March, 1968], No. 13698/69. Heading F2P. A thermally insulated copper pipe 1, has an insulating sheath 2 comprising one, or more, hot-sealed, random, continuous filament fleeces each of which is composed of stretched continuous filaments of a thermoplastic synthetic material, e.g. polyester resins, pololefins, &c. which filaments are bonded together by compressing and heating e.g. on a hot cylindrical roll, the insulating sheath 2 having its outside and/or its inside either provided with an additional covering film of the same, or some other thermoplastic synthetic, material, or hot sealed. The fleeces can be formed by drawing continuous filaments away from spinnerets by means of a high velocity air stream flowing at a velocity between 50 and 350, and preferably 250, metres/sec. and generated in a blowing nozzle and simultaneously stretching the filaments. Then the filaments are deposited on a travelling band in random disposition and compressed between a heated roll and a co-operating pressure band which applies a pressure between 1-50, and preferably 3-6 Kg./sq. cm., at a temperature between 3-50‹ C., and preferably 5-30‹ C., for a time between 2-30, and preferably 5-15, seconds. The surface of the sheath can be sealed by the application of heat and pressure to create a porous skin, which allows the sheath to breath but prevents the ingress of water. The hot sealing may however be carried out to provide an air and watertight outer surface. Alternatively, a flame resistant, or anticorrosion, film may be bonded to the outer surface of the sheath, suitable films respectively being of polyvinyl chloride, polyester and polyethylene, or propylene. As shown in Fig. 4, the sheath 2 has been compressed only at discrete points to create protruberances 5 containing a large number of airoccluding pockets.

Filed: 1919-05-30
Abstract: 153,617. Samain, P. May 30, 1919. Sluice-gates.-The movement of a floating tubular sluice-gate 1 is effected by the admission of water from the reservoir 8 through the pipe 9 and a valve 10, operated electrically or otherwise, to sink the gate on to its seat 16, and by the discharge of the water through a valve 13 into the outflow pipe 12, to open the gate. The gate is suspended by helical springs 4 from a beam 5. If a fracture of the pipe 12 causes the gate to close, a central pipe 3 allows air to enter, so that a dangerously sudden closure is prevented. As an additional safeguard, a vacuum valve 20 is provided to admit air to the pipe 12.

Filed: 1928-05-11
Abstract: 290,668. British Thomson-Houston Co., Ltd., (Assignees of Hardy, A. C.). May 20, 1927, [Convention date]. Optical records and apparatus.-In the production of combined film records by printing a plurality of separate records on to a single film, applicable to the production of a combined sound and picture record, the records which have been developed to a definite degree of contrast designated by gamma are printed on to a film of relatively high resolving power containing a lightretaining dye by separate light beams coloured in such a maner and degree that the product of the gamma of each film and the gamma-infinity of the print shall approximately equal some desired quantity which may be unity. The figure shows an apparatus for printing a sound film 2 and a picture film 14, suitably developed, on to a film 1 containing a suitable dye which substantially confines the image to the surface of the emulsion but is largely washed out on development. The sensitized surfaces of the films are in contact and the sound record 2 is printed by a beam directed through a coloured adjustable wedge 29. The picture record 14 is subsequently printed on the film 1 by a beam directed through an adjustable coloured wedge 38. The picture record may be driven continuously from the sound record, or may be driven intermittently. By determining the gamma, of the separate record and blowing the gamma-infinity of the dyed film for the various colours of the beams, adjustment of the coloured wedges 29, 38 controls the product of thesevalues to the desired value which may be substantially unity. The combination record requires less care in development and reproduces more accurately.

Title: Improvements in or relating to Electric Switches.
IPC: G04F1/00
Filed: 1918-08-28
Abstract: 131,732. Lyster, C. R. C., Russ, S., and Newton & Wright. Aug. 28, 1918. Spring-motor actuation; retarding and time-limit devices; mechanically tripped and released switches. -A switch for closing a circuit for a predetermined short interval, for use in R÷ntgen-ray photography and for other purposes, comprises a rotary member D carrying one or more movable contacts D<3> in a circular path past fixed contacts J, a drum C co-axial with the member D and connected therewith by a ratchet- and-pawl or like device, a lever E connected to the drum by means such as a flexible band C<4>, an operating-spring F connected to the lever E, a stop E<2> on the lever E adapted to be swung out of the path of a lug D<4> on the member D when the lever E is moved to energize the spring, and a separately-controlled device such as a lever H for holding or releasing the member D as required. The member D and drum C are loosely mounted on a shaft B provided with a hand-wheel B<1>. On turning the hand-wheel, a pin B<2> on the shaft engages a pin C<1> on the drum, and the drum is rotated against the action of a spring C<2>, thereby winding up the band C<4> and raising the lever E to strain the spring F. At the same time, a piston G<1> connected to the end of the lever E by a link G<3> is raised to the top of a dash-pot G. When it is desired to operate the switch, the lever H is swung aside in order to release its arm H<2> from a stop D<5> on the member D. The spring C<2>, acting without restraint, then rapidly moves the drum C which drives the member D through the ratchet-and-pawl connexion until one of the contacts D<3> bridges the fixed contacts J. The spring C<2> is not sufficiently powerful to move the contact D<3> past the contacts J, and the circuit remains closed until the lever E, under the action of the spring F, controlled by the dash-pot, overtakes the movement of the drum C, when the spring F completes the movement and opens the circuit. The time during which the circuit remains closed is varied by adjusting the air-leak valve G<2> at the top of the dash-pot by means of a screw G<6>, the adjustment being indicated by a pointer G<5> connected to the screw through multiplying-gearing. A leak-hole G<4> may be provided near the bottom of the cylinder G to release the action of the dash-pot near the end of the stroke. The lever H may be operated manually or by pneumatic or electro-magnetic means. According to the Provisional Specification, the switch may be constructed to give two or more successive closing and opening movements with one setting of the handle, the driving force being provided by a weight or by a series of springs arranged to operate in turn.
