Patent GB-1000136-A (GB)
Title: Insulating material and process for its production
IPC: C03B19/08
Filed: 1962-05-01
Abstract: Insulating material consists of a foamed glass structure in which the walls of communicating or closed macrocells have a closed microcellular structure.  The material may contain at least one porous filler, e.g. expanded clay, foamed slag, pumice slag, foamed glass, brick bats, vermiculite, expanded perlite or hollow spherical silicate particles.  Fibrous materials, e.g. stone wool flakes, asbestos and polyamide fibres, and magnesium oxide may also be added. The foamed glass may be soda-lime glass, slag, basalt or quartz.  The hollow silicate particles are formed by heating thin layers of silicate particles to a temperature of at least 500 DEG  C. for 1-20 secs.  The body may be prepared <PICT:1000136/C1/1> by mixing ground glass or glass-like material, which may or may not be wetted with water or sugar and ethylene glycol, with the filler and heating to form a foam structure.  The foam may have an open or closed cell structure by varying the firing temperature, which for soda-lime glass is about 700 DEG  C. for the open cell structure and about 800 DEG  C. for the closed cell structure.  The firing temperature may be reduced by a flux, e.g. sodium or lead borate or sodium silico-fluoride.  The body may also be prepared by foaming a glass or vitreous powder with a gellable colloidal solution and a foaming agent, the foam then being dried and sintered with the porous filler. The colloidal solution may be water glass, aluminium hydroxide, titanium hydroxide, precondensates of urea and formaldehyde and urea and phenols, phenol modified resorcine resins or bentonite.  The gelling is effected by means of weak acids, e.g. citric or tartaric acids for water glass and oxalic acid for the urea resins, or by the in situ oxidation of sulphurous acid by hydrogen peroxide, or, in the case of resorcine resins by the addition of paraformaldehyde and sodium hydroxide.  When the hollow silicate filler particles are employed they are wetted with water glass solution with or without a soluble salt of an alkaline earth metal, mixed with glass powder with or without other porous fillers and the whole is heated to 700-850 DEG  C. and allowed to cool slowly.  The body may be reinforced by metal inlays.  Fig. 2 shows the dried fired body with macropores 7 and lamellae 8 with micropores 9.

Filed: 1939-06-12
Abstract: 529,919. Telemetering systems. GENERAL ELECTRIC CO., Ltd., and PHILLIPS, F. C. F. June 12, 1939, No. 17119. [Class 40 (i)] The frequency of an oscillator is retroactively controlled in accordance with the position of a meter pointer and its output is transmitted over line wires to a distant meter giving readings proportional to the frequency. In its simplest form, the apparatus comprises a relaxation oscillation generator of the condenser-discharge tube type, the charging potential of which is controlled jointly by the meter pointer and a forked follow-up pointer controlled by a moving coil which receives impulses from a relay connected to the output of the oscillator. The relay also sends impulses over the line to operate a frequency meter. As shown, the charging of the relaxation oscillation generator 9, 10 is controlled through valve 8 the grid of which is connected to meter pointer 1. The output of the oscillator is converted to a square topped wave by a suitably biassed valve 18 for operating relay 22 and transmission over the line. The grid bias of valve 8 is controlled over resistance capacity network 11 ... 15 by engagement of pointer 1 with one or other of the arms of the follow-up pointer 6, 7, which increases or decreases the charge on condenser 13 to vary the frequency of the oscillator. Relay 22 in the output charges and discharges condensers 26, 27 over resistances 28, 29, the charging potential being stabilized by discharge tube 30. Coil 4 of the follow-up instrument is connected in the charging circuit and moves the follow-up element out of contact with the pointer. A relay 36 responding to line impulses charges and discharges condensers 40, 41 ; the charging circuit includes potentiometer resistance 47 the average current in which is indicated by meter 48. The meter reading may be adjusted e.g. when a new circuit element is required by throwing key 44 and adjusting the potentiometer.

Abstract: 1,084,875. Clocks. KILBURG GEOCHRON CORPORATION. April 23, 1965 [April 27, 1964], No. 17185/65 Heading G3T. A geographical clock as described in Specification 1, 050, 178 which uses a map of the globe, includes means moving constantly and continuously to delineate and visibly distinguish the areas experiencing day and night, along with means to cause rectilinear movement of the map relative to the delineating means to visibly represent the changing position of day resulting from earth rotation. The curved line 21 shows the areas at the winter solstice in the northern hemisphere. This changes to the straight lines 22 for the vernal equinox and thence to the reverse curve 24 for the summer solstice. Two flexible blades (26), Figs. 2-20 (not shown) are caused by a driving system to oscillate about central pivots and also to flex so as to form the gradually changing line of delineation. An arrangement of pivoted light filters 33, 34, 36 connected with the driving system, forms the night area, illuminated from behind so as to be in shadow without being obscured for reading purposes. To take account of the ecliptic which creates apparent time as distinguished from mean time, the driving system includes means for oscillating the delineation as required in the direction of the equator. To this end the reeds and filters are mounted on a movable plate 68, Fig. 7 (not shown) oscillated by a cam (45). The sun at zenith is indicated by a crossshaped member 85a which shows behind the translucent map. This member is movable automatically by the drive mechanism, Fig. 2 (not shown). An adjustable latitude scale 100 is provided, along with a scale 102 whereby the equation of time and the sun meridian passage may be read by comparison of the position of the sun mark and the mean hour 12. In a modification, Figs. 18-19 (not shown) this latter scale is adjustable longitudinally to give a direct reading. The hour angle of the sun either apparent or mean and either with reference to Greenwich or any other location, is read from an hour angle scale (110). Manual adjusting means (118, 119) Fig. 2 (not shown) is arranged to over-ride the automatic drive system, so that the device may be turned to any point in time for reading and restored to present time to resume automatic operation. An automatic indicator (78) showing the seasons and zodiacal signs is provided. The date to left and right of the international date line is indicated on a tape showing at window 75.

Title: Improvements in or relating to means for driving pendulums
IPC: G04B1/26
Filed: 1946-06-06
Abstract: 623,190. Clocks. WATKINS, W. F. June 6, 1946, No. 17219. [Class 139] A pendulum driving device comprises an auxiliary mass s so movably mounted on the pendulum relatively to the main mass that the centre of gravity of the system may be altered, an external source of energy, means on said pendulum responsive to said source during one part of the swing and adapted to effect relative movement of said auxiliary mass without mechanical connection with said source and to return said auxiliary mass during another part of the swing. The pendulum 10, Fig. 1. carries an arm 13 to which is attached a bi-metallic strip 14 which supports a ball 15 and which as the pendulum reaches the end of its swing to the right is heated by a flame 16 to bend outwardly to the dotted position shown, thus moving the ball 15 outwardly and in effect giving an impulse to the pendulum. The arm 14 resumes its initial position during the return swing of the pendulum. If desired the bi-metallic strip 14 could be bent back to its initial position by another flame positioned near the other end of the pendulum swing. As the pendulum 10 swings to the right a shield 18 carried thereby cuts off the heat from a flame 19 from reaching a bi-metallic strip 20 which thereupon bends downwardly to separate two contacts 21, 22 which control electro-magnetic hand-driving means. In Fig. 2 a primary pendulum 23 and a secondary pendulum 24 are both driven in the above manner. The secondary pendulum 24 carries a second auxiliary movable mass 28 controlled by a bimetallic strip 27 and the primary pendulum carries a cone 29 (or a wire gauze 31) to control a heat source 30 which co-operates with the bi-metallic strip 27. The arrangement is such that the secondary pendulum 24 is kept in phase with the primary pendulum by movement of the weight 28 and/or by a spring 34 striking abutment 33 on the weight 28. A compound bi-metallic may be used in any of the above cases. In another embodiment, Fig. 4, the pendulum 10 is supported in an airtight casing 50 and carries between a stop 45 and an arm 42 a diaphragm 44. The pendulum in each swing cuts across a beam of light directed on to a photo-electric cell whereupon a pump 46 reduces the pressure inside the casing 50, the diaphragm 44 then expands and a ball 43 carried by the arm 42 is moved outwardly to impulse the pendulum.
