Abstract: 1290053 Silicate grouting composition ITT INDUSTRIES Inc 21 May 1970 [28 May 1969] 24655/70 Heading C3N [Also in Division E1] A composition for producing a chemically grouted structure comprises an aqueous base solution of (a) vegetative phenolic material consisting of condensed type tannins and an aqueous catalyst solution of (b) a water-soluble alkali metal silicate, said polyphenolic material being present in an amount 5-40% based on the weight of said base solution and said watersoluble alkali metal silicate being present in an amount to provide 1-15% of SiO 2  in the silicate compound based on the weight of said polyphenolic material. The alkali metal silicate preferably has a weight ratio of SiO 2  to alkali metal oxide of 1À0 to 3À8. The composition may also contain 0À5-5À0% by weight formaldehyde which may be added as paraformaldehyde based on the weight of said polyphenolic material and acid, preferably sulphamic acid in an amount sufficient to establish a pH of the solution within the range 0À5 to 6À0, preferably 3À0 to 5À0. The composition may be sequentially mixed on the jobsite just before it is injected into the material that is to be grouted. This may be earth, sand or other porous formation. If desired, the compositions may be strengthened by the addition of an aqueous asphalt emulsion, bentonite clay, an hydraulic cement or asbestos. The gels formed from compositions which contain no formaldehyde or acid are of a more temporary character as they tend to disperse slowly in water. The grouting composition may be prepared with all of the possible ingredients in dry form as a multi-component package. Suitable polyphenolic materials are obtained by the extraction of hemlock, firs, spruce, pine or other tannin containing trees or barks with aqueous sodium, ammonium or potassium hydroxide.

Abstract: 1295469 Selective printing E HJERPE 14 Nov 1969 [14 Nov 1968] 55978/69 Heading B6F Arcuate type-bar machines.-A carriage 32, Fig. 7, axially movable along the main drive shaft 23 of the machine, supports a line printing mechanism for pivotal movement about shaft 23 (Fig. 6). The line printing mechanism, particularly for printing numerals, includes a plurality of circle-sector shaped type carriers 2 with radially movable types I. Type selecting mechanism.-The type carriers 2 are pivoted about a shaft 3 to which is keyed a setting bail 4. A hook-shaped dog member 2b pivoted to each carrier 2, embraces the rod 4a of the setting bail 4, Fig. 2. Clockwise rotation of shaft 3 and setting bail 4 causes the type carriers to rotate likewise, until each carrier is individually locked in its selected position by latches 7 engaging sets of teeth (2f, Fig. 1), whereafter the rod is allowed to continue its arcuate motion, Fig. 3. An electromagnet 39 is provided for each type carrier 2. When current flows through the electromagnet, an arm 9, pivoted at 8, is maintained in its cocked position against the bias of a spring 10 (Fig. 4), thereby preventing the latch 7 from engaging teeth 2f. As a type carrier is moved clockwise, selective de-energisation of its associated magnet 39 causes its latch 7 to engage its teeth 2f, Fig. 2. After impression, the arms 9 and latches 7 are reset by the rod 11b (Fig. 4) of a resetting bail (11) engaging the arms 9. The resetting bail (11) is pivoted about a shaft 6 by a cam (12) keyed to shaft 13. Hammer impression arrangement.-Each. type carrier 2 has an associated hammer 19 pivoted on shaft 6. All the hammers are cocked simultaneously by the rod 4b of the setting bail 4 and latched in position by a latching bail 21 (Fig. 1). A cam 24, keyed to shaft 13, pivots the latching bail 21 about the shaft 23, thereby releasing the cocked hammers 19, which are swung for impression by individual springs 20, Fig. 3. Driving mechanism.-The main drive shaft 23 completes one revolution for each printing cycle. Shaft 13 is driven directly by shaft 23 via 1 : 1 ratio gearing 25. Shaft 3 is oscillated by a crank mechanism 25, 26, 27 on shaft 13. A second crank mechanism (30, 31, Fig. 6) on shaft 13 provides the pivoting motion of the printing mechanism about the shaft 23. Electrical input and control.-A punched arcuate plate 41a, Fig. 7, mounted for angular movement with the shaft 3, is associated with a light source 42 and row of photo-cells 44. A binary signal representative of the angular position of the shaft 3, and therefore the typecarriers 2, is emmitted from the photo-cells 44, and compared in a comparator circuit (Fig. 8) with a binary signal from a core storage unit. Coincidence causes the appropriate electromagnets 39 to be de-energized, thereby latching the type carriers in their selected positions. A circuit for supressing insignificant noughts is provided.

The drive shaft 3 has a pinion 3a in engagement with a rack 12a of a table 12 vertically slidable on a body part 7 through ball bearings 13 and the shaft 4 is held by predetermined friction of a member 10 secured by an adjustment ring 9. The ball or balls 11 are interposed between V-shaped groove 1a on the shaft 1 and a conical surface 3b at an angle α on the shaft 3 and a conical surface at a different angle # of a retainer plate 5 secured by a screw 6 to the knob 4a of the shaft 4. Thus rotation of the shaft 1, by a knob 2 or 2<SP>1</SP> while the shaft 4 is held will, due to the difference in the angles α, #, cause rotation of the shaft 3 to move the table 12 by fine adjustment. Coarse adjustment is effected by rotation of either knob 3c or 4a by pinion 3a engaging rack 12a.

Abstract: 1307095 Automatic fire fighting systems FACTORY MUTUAL RESEARCH CORP 20 Oct 1970 49811/70 Heading ASA A method of fire-fighting comprises automatically discharging two extinguishant streams, one of relatively fine and the other of relatively coarse droplets. The method may be embodied in a fixed automatic sprinkler system involving either dual-nozzle sprinkler heads or a conventional single-nozzle head arrangement in which the fine and coarse sprinklers are interspersed. The nozzles are thermally actuated independently or simultaneously as required. Preferably the fine droplets are less than 1 mm in diameter, and the coarse greater than 2 mm. Figs. 3-5 illustrate alternative dual-nozzle sprinkler heads. In Fig. 3 the fine nozzle is jet nozzle 10 normally closed by quartz bulb 16, and the coarse nozzle is pendant nozzle 17 formed with discharge opening 18 and serrated distributor plate 20 and normally closed by cap 26 co-operating with link lever 22 and fuse 24. Both nozzles communicate with T-fitting 12 whose inlet is connected to water supply pipe 14, and a restricted orifice is situated upstream of outlet 18 to reduce the velocity and thus the pressure of the extinguishant issued from coarse nozzle 17. Bulb 16 may be adapted to release at a lower temperature than fuse 24. In Fig. 4 the water supply line 30 is horizontal, and X-type fitting 32 communicates with pendant coarse nozzle 17 and radial spray or fog nozzle 38 equipped with link lever fuse release 40. In Fig. 5 both nozzles are actuated by release 42. Valve 44 having serrated skirt 46 and stem 48 is seated against supply line 14. On actuation, the valve moves down so that skirt 46 rests on orifice plate 28, thereby opening both nozzles. Figs. 6-7 (not shown) illustrate an arrangement of separate interspersed fine and coarse sprinkler heads.
