Patent GB-627264-A (GB)
Title: Method for the production of bricks and similar building materials
IPC: C04B33/22
Filed: 1946-10-23
Abstract: A material suitable for the manufacture of bricks is prepared by subjecting raw clay to a preliminary heating to a temperature below the temperature at which sintering of the clay occurs, preferably to 850 DEG  - 920 DEG  C., mixing the product while still hot with a further quantity of raw clay which may be different from the original starting material, and rendering the mixture homogenous.  The preliminary heating may be carried out by increasing the temperature by steps, the starting temperature being preferably 300 DEG  - 400 DEG  C., and the process taking between 15 minutes and 3 hours, preferably 1 hour.  Preferred proportions for mixing are 1 part by weight of raw clay to 1 - 2 parts by weight of the heated product.
Patent GB-648903-A (GB)
Title: Improved process for separating sodium chloride and potassium chloride
IPC: C01D3/04
Filed: 1947-11-27
Abstract: Sodium and potassium chlorides are separated by a process involving the formation of a double salt CaCl2.KCl formed in solution above 37.7 DEG  C.  (1) A solid admixture may be extracted with calcium chloride solution of suitable concentration, say at 95 DEG  C., and the double salt produced by evaporation at above 37.7 DEG  C. or by cooling to somewhat below the extraction temperature, or by adding solid calcium chloride.  The double salt is separated and treated with calcium chloride solution or with non-saturated calcium-potassium chloride solution below 37.7 DEG  C., e.g. 0-15 DEG C, to form the simple salts from which potassium chloride may be separated.  Alternatively, the solid admixture may be treated above 37.7 DEG  C. with calcium chloride solution of such high concentration that the double salt crystallizes immediately, and is separated from suspended solid sodium chloride by flotation &c. (2) Solutions of the two chlorides are treated with calcium chloride either solid or in solution, and when the greater part of the sodium chloride has precipitated, it is separated, and the solution is then evaporated to deposit the double salt, which is treated as before. If the solution from which the double salt is to be separated has a very high concentration of calcium chloride, some of this is removed by crystallization immediately below 37.7 DEG  C.

Title: Improvements in and relating to diaphragm horns and alarms
IPC: G10K9/10
Filed: 1919-12-16
Abstract: 159,676. Gratze, E. V. Hayes-. Dec. 16, 1919. Addition to 18116/14. Diaphragm horns.-In the diaphragm horn described in the parent Specification, a friction clutch is substituted for the one-way clutch previously used. As described in the parent Specification, a stud b<1> on the diaphragm is struck by teeth c on a weighted wheel c', which can be set in rotation by turning or depressing the knob e<3>. When the knob e<3> and sleeve e<2> are depressed, the nut e<1> causes the screw-threaded spindle e to revolve and, according to the present invention, it thereby depresses a fibre or like cone c<3> into frictional engagement with the weighted wheel c<1>, to which rotation is thus imparted. When the motion of the rod e is reversed, the cone c<3> is disengaged, but its upward travel is limited by the stop f. In modifications, the part of the rod e carrying the cone may be formed with a screw of less pitch than the rest, the cone may be replaced by a flat disc engaging the surface of the wheel, or, as described in the parent Specification, the rod may be operated by pulling instead of pushing.

Title: Treating glass surfaces
Inventor: STANLEY ROBERT HOLROYD
IPC: C03C17/32
Filed: 1964-08-05
Abstract: Glass surfaces are treated to prevent chipping and/or scratching by applying to the surface of a glass body a polymer of an organic titanate say of general formula: Ti(OR)4 where R represents an alkyl, aryl alkylsubstituted aryl group and is the same or different, heating the glass body to above the temperature at which the polymer forms titanium dioxide and thereafter cooling and recovering the treated glass body.  Each polymer molecule may contain 2 to 10 titanium atoms.  The polymers may be produced by adding water to the titanate monomer in predetermined amount say 0.5 to 1.5 mol water per mol titanate monomer to control the molecular weight of the polymer. The water may be added in solution in an organic liquid miscible with monomer, e.g. monohydric alkanols.  Polymers containing 2 to 6 titanium atoms can be applied in undiluted form; higher molecular weight polymers may be applied in a solvent.  The polymer may be applied at a suitable temperature as the glass body cools after manufacture, or applied to the cool body which is then heated to the desired temperature, say in the annealing of the glass.  The temperature may be 400 DEG C. to 700 DEG C, and the glass body may be cooled slowly in air after treatment.  The polymer may be applied by spraying, dipping or flushing.  A surface active agent, preferably a non- ionic or an anionic compound, may be applied to the glass surface before or with the polymer.  The glass body may be a glass container, or window glass.  In the Examples, glass slides are treated.

Title: Snap-action electric switch
Inventor: MASON HOWARD FISHER
IPC: H01H13/36
Filed: 1957-10-14
Abstract: 837,964. Retractive switches. MASON ELECTRIC CORPORATION. Oct. 14, 1957, No. 32016/57. Class 38 (5). The fixed and moving contacts of a switch are interconnected by a snap-acting spring device and the fixed contact is arranged to be yieldable so that as the contact closing force is applied to the moving contact the spring device causes the fixed contact to yield and so prevent closure of the contacts until a predetermined force is applied when the spring device snaps over and allows the contacts to close. Fig. 6 shows a switch comprising an operating member 137 universally pivoted at its lower end and carrying moving contacts 136 and an operating knob 138. Fixed contacts 135 are mounted on resilient metal strips 120 eachof which carries a housing 121 for a snap spring 125. Insulating buttons 130 pass through apertures in each strip 120 and abut the corresponding snap spring 125 and the operating member 137. Movement of the operating member to either side causes the appropriate button 130 to push the fixed contact back until the spring 125 snaps over and the contacts close. Fig. 16 shows a switch having a pivoted member 230 and co-operating pairs of contacts 251, 261 and 262, 281. Housings 249, 283 are provided for snap spring and insulating buttons 247, 284. The snap springs in each housing may be of the same stiffness so that movement of the member 230 to the right causes simultaneous closure of the contacts or the springs may be of different stiffness so that the pairs of contacts close sequentially. Alternatively, springs of the same stiffness may be located at different distances from the contacts to provide sequential operation. A rotary switch, Figs. 12-14 (not shown), and a pushbutton switch, Fig. 18 (not shown), are also described.

The guides for the upper ram-plate d, Fig. 2, consist of standards e of rectangular section secured at each end of a base-plate a, and the upper ram-plate is provided at its ends with projecting arms f forming rectangular grooves to engage the standards e. Strap plates o attached across the outer ends of the arms f engage the outer faces of the standards. The shaft g, supported between bearings at the upper ends of the standards e, is provided with a central operating handle h, and has cams i formed upon it between the handle and the bearings to engage surfaces j on the upper ram-plate, when the handle is depressed. The upper ram-plate is raised by restoring the handle to the vertical position, plates k secured to the ends of the cam shaft being provided with cam slots l, Fig. 1, engaging rollers on studs n attached to the strap plates o on the ends of the upper ram-plate. The width and contour of the slots l is preferably such that the weight of the ram-plate is allowed to assist in its descent. The stop plates p are provided with inclined upper edges and are adapted to abut against the lower edges of the strap plates o which are correspondingly shaped. The stop plates p are held against the standards e by bolts q passing through slots r provided in the plates, so that after slackening the bolts and plates can be adjusted longitudinally by means of screws s which are screwed into the standards e and have flanges t to engage within grooves in the stop plate. Graduations may be provided on the screws s or plates p to facilitate adjustment. The surface b of the base-plate a is adapted to support a slidable forme c or a printing-bed plate or the like.
