Title: Windshield clearing system
IPC: B60S1/48
Filed: 1949-05-04
Abstract: 663,584. Windscreen wipers. TRICO PRODUCTS CORPORATION. May 4, 1949 [May 5, 1948], No. 11957/49. Class 138 (i) [Also in Group XXVIII] A windscreen washer comprising a pump for supplying liquid from a reservoir to a spraying nozzle has means for actuating the pump on its intake stroke to withdraw liquid from the reservoir and manually controlled power means for actuating the pump on its delivery stroke to supply such liquid to the nozzle. The power means may be the expansion of a spring which is compressed by induction manifold suction, or it may be compressed by a solenoid or an electro-magnet. As shown, the pump is housed in a cylinder depending from the lid of the fluid reservoir 7. The parts are normally in the position shown. At the lower end of the cylinder is a pump chamber 8 and movable within the chamber is a fluid-displacing member 9 having apertures 11 closed by flap valves 10. The member 9 is carried by a tubular member 18 having at its upper end a flange 24. The member 9 is normally held down by compression spring 12. On pressing the manual control valve 5, induction depression is communicated from the manifold 4 by pipe 6 to chamber 14, which causes the piston 15 to rise and be held in its uppermost position by latch 22. Piston 15 is fast with a rod 16 the bottom end of which carries a flange 19 against which abuts a spring 17, whereby the spring 17 is now compressed. The upper end of spring 17 abuts the flange 24, so that the spring 17 then expands and raises the fluid-displacing member 9 so forcing fluid through pipe 23 to the nozzle 1, the spring 17 overcoming the spring 12. When member 9 reaches the top of its stroke, the flange 24 trips the detent 22 and releases the piston 15, and all the parts return to the position shown, since release of the manual control 5 has put the spice 14 above piston 15 at atmospheric pressure through port 26. The manually controlled valve 5 may be replaced by a pushbutton switch which energises a solenoid on top of of the container; this raises and latches the piston 15 as above.

Fig. 5 shows two overlapping rope lengths, each length being within a. ductile tubular insert 3, 5. The surrounding ferrule 1 has been compressed to cause the inserts 3, 5 to grip the rope lengths. In Fig. 5 the central core of each rope was first removed and replaced by a core 9 of ductile metal so that when the ferrule 1 is compressed the ductile core 9 undergoes plastic flow between the strands 10 of its rope. A single ductile insert (11) of Figure 8 cross-section, Fig. 6 (not shown) may be used to define two bores, one for each rope length. In Fig. 5 the lengths of rope are side by side within the ferrule; alternatively, one of the ropes can be unlaid so as to encompass the insert around the other rope. The ferrule 1 may be of metal and be less ductile than the inserts 3, 5 or (11), but more ductile than the component wires of the rope. The component wires of the ropes may be of ultra-high tensile steel, alloy steel, non- ferrous alloys, and both natural and synthetic fibres. The ferrule may be of malleable cast iron, mild steel, or plastics material.

[Also in Group XVI] Automatic changeover from a fast winding to a reading speed is provided when a desired section of an information tape reaches a sensing means responsive to an auxiliary signal on the tape. The tape may be magnetic but the machine exemplified uses punched tape. Punched paper tape 1 is fed from a reel 2 between rollers 4, 5, a brake 13, a photo-electric reader 14, a reading head 15, rollers 17, 18, into a magazine 16, and between rollers 21, 22 before being wound on to a reel 3. The rollers 4, 17 and 21 are driven by a common drive, while the rollers 5, 18 and 22 can be moved away from their respective rollers upon energization of electromagnets 10, 20 and 24 respectively. The reels 2 and 3 are rotated at the same angular speed by a driving motor 27, Fig: 7 (not shown), the reels being braked by electromagnetic friction brakes. The tape 1, Fig. 1, has a plurality of sections, e.g., for carrying specific information, the tape being fed at a high speed until the required section is adjacent the tape reader 15. The required section is sensed by the reader 14 and a counter, not shown, the tape being provided with an additional perforation channel in alignment with the reader 14, such that when a predetermined number of pulses, representative of the required section have been counted the counter applies the brake 13 to stop the tape. The motor 27, Fig. 7 (not shown), is disconnected while electromagnet 20 withdraws the roller 18 and brakes 32, 33, Fig. 2 (not shown), are applied on the reels 3, 2, Fig. 1, respectively. When the desired information has been read from the particular tape section, a contact, not shown, is closed which energizes the motor 27, Fig. 7 (not shown), in a direction to rewind tape quickly on the reel 2. The roller 5 moves away from roller 4 and the roller 22 is pressed against the roller 21. Stop contacts under the control of the counter, not shown, are opened when a predetermined length of tape has been rewound on the reel 2. These contacts stop the motor 27, Fig. 7 (not shown). A safety device, not shown, may be provided to stop the reels 2, 3 in the event of failure of the counter, not shown.

Title: Process for the purification of silicon chloroform
IPC: C01B33/08
Filed: 1959-04-13
Abstract: Silicon chloroform, obtained by reacting silicon containing 0,08-2,5% by weight of aluminium and gaseous hydrogen chloride, is purified by cooling to 40 DEG -100 DEG C. to precipitate aluminium chloride and other impurities and subsequent separation from residual gases, e.g. by condensation by cooling.  A static or fluidized bed of granular silicon containing aluminium is contacted at 210 DEG -330 DEG C. with anhydrous hydrogen chloride, advantageously diluted with a gas inert under the conditions, e.g. argon, nitrogen, or hydrogen.  The reaction is preferably carried out at superatmospheric pressure, say 6 atmospheres.  Reaction gases so formed are passed directly to a separator, where they are cooled to 40 DEG -100 DEG C., whereby the aluminium trichloride and other impurities separate out.  The residual gases contain silicon tetrachloride and hydrogen and are passed to a condenser, where they are cooled to -20 DEG C. to effect condensation and separation of silicon chloroform.  Residual gases may be recycled to the process as diluent for the hydrogen chloride.
