Title: Ethyl silicate binder
IPC: C04B28/24
Filed: 1970-11-05
Abstract: 1356249 Silicate hydrolysates ZIRCONAL PROCESSES Ltd 21 Oct 1971 [5 Nov 1970] 52695/70 Headings C1A and C1J [Also in Divisions C3 and C4] In the production of a hydrolysate by the mixing of ethyl silicate, at least one monohydric totally water miscible alcohol solvent and dilute strong aqueous acid (a) the proportion by volume of acid added to ethyl silicate added is not less than 0À25 : 1 and not sufficiently great as to impair the homogeneity in the resulting hydrolysate, (b) the volume of alcohol solvent added is not less than 5 times the volume of acid added and (c) the acid added is not less than 0À25 normal. A "strong" acid is defined to be an acid as strong as "orthophosphoric acid". The alcohol may be methyl alcohol, ethyl alcohol, propyl alcohol or isopropyl alcohol and the acid, hydrochloric, sulphuric, orthophosphoric or sulphamic acids. The hydrolysate may be gelled with alkali, e.g. ammonia, an aqueous/polyhydric alcohol dispersion of lightly calcined magnesia or an aqueous solution containing ammonia and an ammonia salt of a carboxylic acid (e.g. the formate, acetate, benzoate, and citrate). The use of a wetting agent, i.e. an oleic acid-ethylene oxide adduct in an ammonia solution containing ammonium acetate is described in the specification. Methyl ethyl ketone may be added to the hydrolysate to improve storage life. In a typical example using hydrochloric acid, ethyl alcohol (64 over-proof) was mixed with iN hydrochloric acid (20 ml) and ethyl silicate (80 ml.). In another typical example using orthophosphoric acid, water (40 ml.) containing orthophosphoric acid (4 g.) was mixed with 640-p-ethyl alcohol (220 ml.) and ethyl silicate (160 ml.). In Example 6 sulphamic acid (20 g.) were dissolved in water (20 ml.) and to the solution was added 640-p-ethyl alcohol (110 ml.) and ethyl silicate (80 ml.). Shaped refractory articles may be made by mixing the hydrolysate with an alkaline gelling agent, forming the mixture into a slurry with powdered refractory aggregate, casting into moulds, allowing gelation to take place, and firing. Refractory aggregates may be one or more of (a) aluminium oxide, (b) aluminium silicate, (c) aluminosilicate, (d) magnesium oxide, (e) magnesium silicate, (f) zircon, (g) zirconium oxide, (h) silicon oxide, (i) silicon carbide, (j) spinel, (k) fire clay grog, (1) calcined china clay, (m) kaolin, (n) sillimanite, (o) mullite, (p) magnesite, (q) chromemagnesite, (r) olivine and (s) forsterite. The use of (a), (n), (f), (f) + (g) and (a) + (1) is exemplified.

Title: Alarm clock mechanism
IPC: G04C23/02
Filed: 1973-11-14
Abstract: 1455306 Alarm clocks GENERAL ELECTRIC CO 14 Nov 1973 [16 Aug 1973]  52948/73 Heading G3T In an electric alarm clock having a vibrator 120, Fig. 4, which is normally restrained by a shut-off lever 20 but is released to sound the alarm at a preset time, the lever 20 moves longitudinally to release the vibrator under the force of a spring 148 when a latch portion 150 of the lever is moved out of a notch in frame plate 36 by the action of a first cam 108, and the central portion of the lever is subject to the action of a second cam system 44, 46 which, shortly before the pre-set time, tilts the lever about a longitudinal axis thereof to bring a finger 166 on the lever into contact with the cam 108. As shown the clock is a digital clock and the cam 108 is coupled to a units of minutes indicator actuating member 12 for rotation once every ten minutes. The cam 44 is rotated once every twelve hours by the clock mechanism and is moved axially when a cut-out on the cam becomes aligned with finger 46 on an alarm time-set cam 42. This movement is produced by the force of a resilient switch contact arm 22 via a shaft 26 and allows contacts 33, 34 to close and energize a radio. The movement is, however, prevented if a cam 82 on a manually operable selector shaft 80 is in the NO WAKE position shown, since a slotted arm 68 of a lever 62 then prevents axial displacement of the gear 40 to which the cam 44 is attached. The shaft 80 also has a RADIO WAKE position in which the lever 62 is free to move and the switch contacts to close but the shut-off lever 20 is still held in the restraining position by a finger 104 on the shaft. In a third ALARM position of the shaft Fig. 5 (not shown) the switch and vibrator are freed in succession as described above. Depression of a drowse button (218), Figs. 1 and 8 (not shown) causes a lever (200) to pivot and move the latch portion 150 of the lever 20 back into the frame plate notch, silencing the vibrator, until the cam 108 again depresses the finger 166 a few minutes later and releases the lever 20 once more. An automatic vibrator silencing mechanism  driven by a gear (222), Figs. 13-15 (not shown) which rotates once per minute is also described. The switch is also controlled by a member 24 fixed to a lever 94 the end 96 of which rides on an ON-OFF-SLEEP cam 90, allowing the switch to be controlled independently of the vibrator.

Abstract: 1283860 Spray carburetters ROBERT BOSCH GmbH 27 Nov 1970 [1 Dec 1969] 56431/70 Heading F1B Fuel injection system for an I. C. engine having continuous injection into the manifold and separate ignition comprises a butterfly throttle valve and a measuring element arranged in series in the intake manifold, the measuring element being displaced in proportion to the air-flow through the manifold and actuating the movable part of a fuel valve to meter a quantity of proportional to the air-flow, the measuring element being displaced against a normally constant return force and there being an electromagnet, the field strength of which is variable in dependence upon engine characteristics, and which acts to vary the return force. Combustion air is drawn through a filter 2 and as it enters a divergent part 3 of the induction pipe, acts on a plate 4 mounted on a lever 9. The air passes through a flexible section 5 of the induction pipe in a rigid section 6 containing a butterfly throttle valve 7. The lever 9 is pivoted at 10 and has a lug 11 which actuates a valve spool 12 controlling the flow of fuel pumped through a line 19 to passages 26 and hence to the injection nozzles. The lever acts against the force of a spring 28 having a flat load/deflection characteristic which can be modified by the effect of an electromagnet, the field strength of which is dependent upon engine conditions e. g. load and temperature. The electromagnet comprises a coil 30 and an armature 29 which transmits the force of the spring 28 to the spool 12. To ensure that the force of the magnet does not vary due to its movement, the end of the armature is conical and a soft-iron core 31 has a corresponding conical aperture. In a modification, Fig. 2 (not shown), the normally constant return force is produced by the pressure of the fuel acting on the end of the spool. The magnet armature is formed as a sleeve which carries a winding externally and is surrounded by an annular soft-iron core, and a contiguous permanent magnet. A soft iron plate which contacts the face of the magnet remote from the annular core, carries a pin which projects into the bore of the magnet sleeve. A pin projecting axially from one end of the sleeve engages the end of the spool so that the force produced by the magnet augments the spring force.
