Title: Improved manufacture of pigments and pigmented products
IPC: C09C3/00
Filed: 1927-08-30
Abstract: 277,949. Stubner, E. C. de. Sept. 23, 1926, [Convention date]. Colouring plastic compositions.-For the colouring of products such as collodion, celluloid, and artificial leather, pigments formed by precipitation in aqueous media are dehydrated by adding a fluid miscible with water and compatible with the material, or some constituent thereof. which is to be coloured. The precipitate is washed, and preferably filter-pressed or centrifuged to remove surplus water; it is then treated with the appropriate fluid. For example, for colouring cellulose formate, pyridine is suitable; for cellulose triacetate or triethyl cellulose, alcohol or acetone. The fluid may be continuously applied to the precipitate, as by percolation, the fluid being recovered and dehydrated for reuse. Products having a cellulose base may be pigmented by forming the precipitate in situ on the material and then effecting dehydration with a water miscible fluid in which the cellulose derivative is insoluble, but which is compatible with the solvent in which the cellulose derivative may be subsequently dissolved. In an example lead chromate is precipitated from solutions of potassium bichromate and lead acetate in the presence of hydrated soluble cellulose, and the product dehydrated with alcohol. The dehydrated coloured product may be employed for making coloured celluloid, artificial leather, &c. Metals such as copper, silver, antimony, gold, &c., which may be produced by precipitation in aqueous media, may be used as pigments.

Title: Improvements in or relating to electric signalling installations
IPC: G08B3/10
Filed: 1927-08-30
Abstract: 283,944. Siemens & Halske Akt.- Ges. Jan. 21, 1927, [Convention date]. Addition to 280,503. Order apparatus.-Relates to a signalling system for summoning persons, transmitting orders, &c. in which impulses transmitted by a sender WS actuate, relays to produce a code signal at the audible alarms E. The impulse sender WS, which is of the kind used in automatic telephone systems, is in series with a slow-release relay S and a relay J which repeats the impulses to the. motor magnet D of a stepping switch 1D - - 4D. The operation of relay S excites relay R which locks itself and the release of relay S operates relay T which short-circuits relay Sand holds relay J attracted. The closing of contact t3 operates relay P impulsing the motor magnet D1 and the relay J1 which interrupts the circuit of P and operates relay U successively closing relays V, W, X, delivering an impulse to the alarm E. The operation of relay X energizes relay P impulsing D, J, and the sequence of operations is repeated to again impulse the alarm E. Thus the alarm E as shown receives impulses on each contact being engaged by the arm 1D1 controlled by the magnet D1. The impulse is, however, long or short according to the setting of the arms 1D - - 4D controlled by the magnet D to connect the arm 1D1 to the relay W or to the relay U. Unused contacts associated with the arm 1D1 allow the stepping by D1, J1 to proceed and the used contacts may be multipled to obtain a repetition of the signal. The last contact of 1D1 operates relay C which holds itself over c3 and actuates P causing D1 to return the arm 1D1 to normal, thus de-energizing P. Operation of the key RT removes the short-circuit on relay S and de-energizes the impulse relay J, impulsing motor magnet D and returning contacts ID - - 4D to normal so that relay R is short-circuited and deenergized so that all relays return to normal.

Title: Improvements in and relating to air brake systems
IPC: B60T13/66
Filed: 1920-08-04
Abstract: 170,960. British Thomson - Houston Co., Ltd., (General Electric Co.). Aug. 4, 1920. Fluid-pressure.-To prevent the brake cylinder supply and exhaust connections of.an electricallycontrolled pneumatic brake system from being simultaneously opened the application magnet valve is arranged to control a supply of air by which the release valve is operated so that when the supply valve is open the release valve cannot be operated or, if already open, will be closed. A straight air system is shown comprising a straight air train-pipe to which the brake cylinders and the driver's combined valve and switch are directly connected so that the brakes can be applied and released by the driver's valve independently of the electric control. The valve mechanism, Fig. 2, for electric control is connected at 1 to a second train-pipe connected directly to the main reservoir, whereby pressure air is normally supplied through a magnet valve 42 and passage 21 to the upper side of a valve 11 to close the supply passage 14, 15 to the cylinder connected at 8. A release magnet valve 30 normally connects a passage 32 leading from a piston 12 to an exhaust port 33 so that the valve 22 controlled by the piston 12 is held in position by a spring 23 to close the brake cylinder exhaust passage 15, 17, 19. To apply the brakes electrically the valve magnet 22 is energized to cut off the pressure supply from the passage 21 and connect it to the exhaust port 29, the valve 11 being then opened by the pressure acting on its under surface. To release the brakes, the valve magnet 30 is energized to close the passage 32 to the exhaust port 33 and connect it to the passage 21 and, provided the application magnet valve is deenergized as shown, pressure air is thus admitted by passage 21 to the upper side of the piston 12 to open the valve 22. If from any cause both magnets 27, 30 are simultaneously energized, connection of the source of pressure direct to the atmosphere through the valve mechanism is thus prevented. In the driver's valve and switch shown, the release position for pneumatic and electric control is the same

Title: Improvements in railway signalling apparatus
IPC: B61L21/04
Filed: 1931-08-20
Abstract: 379,846. Railway signals. BRITISH POWER RAILWAY SIGNAL CO., Ltd. and KNOX, H. S., Windsor Works, Slough, Buckinghamshire. Aug. 20, 1931, No. 23484. [Class 105.] A single operating lever 1 operates the required one of a number of signals by means of selector apparatus 3 comprising a pair of slides 4, 5, one or both of which are normally mechanically locked by electrically - controlled means but one of which is freed and the other locked when an electromagnet of the control means is energized so that the free slide may then be actuated by the hand-lever to operate the signal so selected. The control means is shown in detail in Fig. 3 and comprises an electromagnet 20 with a counterweighted armature which actuates.a bolt 17 to lock one or other of the slides 4, 5, the slide 5 being locked, when the magnet is de-energized, by the dropping of the counterweighted armature. Operation of the hand-lever 1 in such conditions will lift a pulley 9 with consequent displacement of that end of a chain 8 which is attached to the free slide 4 which then actuates a signal chain 6. If the electromagnet 20 is energized the slide 4 is locked and slide 5 is free so that a second signal chain 7 would be operated. A pulley 12 at the lower end of the member 11 engages a chain or wire 13 attached to the slides 4, 5 to ensure their return when the hand-lever 1 is restored. In addition the member 11 carries a finger 31, Fig. 3, having a bevelled face 32 to engage a bevelled aperture 34 in the bolt 17 which is thereby positively returned to lock the slide 5 should the counterweighted armature not have dropped when the magnet was de-energized. The selector shown in Fig. 4 has two magnets 40, 50 each actuating a locking bolt 47 or 57 for the slides 4 or 5. The bolt lengths are such that a withdrawn bolt butts against the other bolt to prevent the latter being withdrawn. The member 11 positively restores the bolts to the locking position by engaging the armatures 42, 52. An arrangement is shown in Fig. 5 whereby two hand-levers each normally operating its own signal may operate a call-on signal common to the two levers. Two selectors 35, 36 are provided, the normally free slides of which have a chain 556 passing round a pulley 58. When a call-on signal is to be given, the magnet is not energized and so the normally free slide is not locked so that the operation of the hand-lever raises the pulley 58 and a connected pulley 60 actuates the chain 63 leading to the call-on signal. The armature of the selector magnet 20, Fig. 3, operates a circuit-controller 28 for indication or other purposes. The selector magnet itself may be controlled by railway points, by a track relay, or by a manual pushbutton ; an economy switch would be provided actuated by a catch handle or by the initial movement of the handlever or of the member 11. In place of the chain and pulley actuation of the slides 4, 5 a rack and pinion gear may be used. Slack in the signal connections may be taken up by attaching the connections to screw-adjusted members on the slides.
