Title: Improvements in Alarm Systems for Jails, Safe Deposits, and the like
Inventor: BALLOU ERNEST H
Filed: 1902-01-14
Granted: 1902-05-08
Abstract: 980. Ballou, E. H., and Beard, E. H. Jan. 14. Alarms,burglar and like; indicators or annunciators. - In alarm systems for use in jails, safe deposits, vaults, &c., an alarm is sounded when egress or entrance is forcibly effected, while an indication is also given of the general location of the origin of the alarm. Fig. 1 shows a diagrammatic view of the system as applied to prison cells 8 opening off corridors 11, the ends of which are closed by gratings 12, 13, the gratings 13 being provided with doors 14. The gratings 12, 13 and the bars 15 of the cells, are tubular, and are connected together in series in each wing, each series being in communication with a reservoir 16 of compressed air located beneath the corridor 10 &c. Each series of tubes is also provided with an electric contact-maker, Fig. 3, connected in circuit with a battery 26, an alarm bell, and an annunciator 27. The air pressure within the tubes acting on the diaphragm 18 holds the contact-maker 21 clear of the contacts 22, 23 in the alarm circuit. When one of the tubes is cut or broken, the pressure is released, and the spring 28 closes the alarm circuit. The annunciator 27 indicates the wing in which the break occurs. An alarm is also given when a door is opened, the release of the air pressure being effected through the door hinge, Fig. 2. The leaf 30 fixed to the door carries a hollow pintle 31, which bears in a socket 32 fixed to one of the bars of the grating. A tube 34 in the socket is in communication with one of the tubular bars through a T-connection 36. When the door is closed, the tube 34 is closed by the pintle 31, but when the door is opened, the lateral opening 37 in the pintle registers with the tube 34, and permits the air to escape, so completing the alarm circuit.

Title: An Improved Method of and Means for Producing Lead Carbonate, Commercially Known as White-lead.
Inventor: HYDE GEORGE THOMAS
Filed: 1902-09-12
Granted: 1902-12-04
Abstract: 19,980. Hyde, G. T., [Union Lead and Oil Co.]. Sept. 12. White lead.-Granulated or other finely-divided lead is fed through a hopper 8 to a pulverizing-mill 1, of any ordinary construction, that shown having fixed inwardly-projecting fingers 2 and a rotating shaft 4 fitted with radial fingers 3, which are carried round between the fingers 2. The lead, when pulverized sufficiently, is withdrawn by a blower 10 and passed up a tube 11 to the inlet tube 12 of a vessel 13. This tube has a steam jet 28, which injects a supply of acetic-acid vapour and carbonic-acid gas from the tube 29 into the vessel 13. The tube enters the vessel tangentially, so as to give a rapid circulation to the air and gases. White lead forms, gradually falls, and collects in the hopper 14, from which it is removed through a gate valve 16 and an outlet 15. Some of the powdered lead and gases may escape through an outlet pipe 17 to a second similar vessel 18, and from that to a third 19. One or any desired number of these vessels may be provided. The last is, in each case, covered with a screen 26, to prevent the escape of dust particles while permitting the escape of the gases. In another form of apparatus, the finely divided lead is introduced into the top of a cylindrical vessel by means of perforated tubes, within which work screw conveyers leading from a supply chamber. The lower part of the cylinder is surrounded by a tube, from which jet pipes lead the required gases and vapours into the interior.

Title: An Improved Fish Food Preparation.
Inventor: DAVIDSON JOHN
Filed: 1902-09-30
Granted: 1903-07-30
Abstract: 21,293. Davidson, J. Sept. 30. Food preparations ; preserving fish.-A food preparation is made from heavily-salted and dried fish, by removing the bones, skin, and discoloured parts, breaking up into a fluffy or feathery state by teasing or combing, drying till the surfaces become sticky, and then mixing with cornflour and the like till the particles become thoroughly coated. Flaked tapioca, rice, or other cereal, may be added to the whitened fish, to act as a binding-material. The cornflour prevents conduction of moisture, and thus indirectly preserves the fish. It is washed out with the salt when the fish is steeped in water before cooking.

Title: Improvements in Electrical Influence Apparatus suitable for the Ignition of Gases and Inflammable Vapours and for other purposes.
Inventor: ECKSTEIN AUGUST
Filed: 1902-11-17
Granted: 1903-09-17
Abstract: 25,195. Eckstein, A., and Coates, H. J. Nov. 17. Drawings to Specification, Influence machines for the ignition of gases, inflammable vapours, explosives, and hightension fuzes, for use in producing high-tension currents for ozone, X-rays, and the like, and particularly for igniting the explosive mixtures used in gas, petrol, and other internal-combustion engines. The influence machine consists of a case, either of suitable insulating-material, or of metal, such as aluminium, lined with insulating-material, carrying a central axle upon which is mounted one or more dielectric plates, with suitable metal carriers or sectors arranged in the usual manner. The carriers are, however, preferably disposed between two dielectric plates, such as ebonite, the field or inductor plates being mounted close up on each side of the pair of plates, the insulating-mount also carrying the charging, collecting, and neutralizing conductors. To minimize leakage, the carriers may be embedded in the dielectric, except for a small projection for forming, or joining up to, the contact - pieces, while, instead of all the plates revolving in the same direction, some may be arranged to rotate in the opposite direction to the rest. The plates may be replaced by cylinders if desired, and a suitable condenser may be placed inside the case if a capacity is necessary in the working circuit. The Provisional Specification states that, with an ebonite dielectric, the embedded carriers may be vulcanized therein to improve the mechanical and electrical efficiency of the apparatus.

Title: Improved Shuttle Changing Mechanism for Looms.
Inventor: SLACK ROBERT
Filed: 1903-04-07
Granted: 1904-04-07
Abstract: 7986. Slack, R., and Tod, J. N. April 7. Loom shuttle-changing mechanism.-The shuttle - changing mechanism is operated upon the drop - box principle. When the weft fails, or, if the loom is fitted with a device such as is described in Specification No. 10,022, A.D. 1902, when the weft is substantially exhausted, any ordinary mechanism acts through a rod 7 to lower the boxes 4, 5. The hinged bottom of the lower box 5 is freed from the action of a fixed stop, so that the bottom swings open, and the exhausted shuttle falls. A fresh shuttle in the upper box is picked to the other side of the loom, and then the boxes are raised again. A lever 20 is depressed by a cam, so that a fresh shuttle 15 is pushed from a fixed table 29 into the then empty upper box, when the lay is in its forward position. The hinged lid 17 of the upper box is simultaneously raised, to admit the shuttle, by a continuation catch 25 of a lever 24, fixed to the lid, being depressed by a lever 22, which is connected by a rod 23 to the lever 20. When the lever 22 passes the end of the catch 25, the lid falls again.

Title: Improvements relating to the Distribution of Steam or other Actuating Fluid in Air Compressors of the Direct-acting Non-rotating Type.
Inventor: WATSON HENRY BURNETT
Filed: 1903-08-24
Granted: 1903-09-24
Abstract: 18,219. Watson, H. B., and Billetop, T. C. Aug. 24. Air - compressing engines ; valve gear. -Relates to the distribution of steam or actuating-fluid in air-compressors of the direct-acting non-rotative type, and more particularly to means for adjusting the tappets, accessible from the outside of the machine. The steam cylinder 6 is mounted above the air cylinder, and its cover carries the steam chest 8. The arrangement of valve and steam passages is or may be substantially the same as that described in Specifications No. 3645, A.D. 1900, and No. 24,553, A.D. 1901. The main slide valve 9 works in a bridle 10 transversely to the axis of the cylinder and is operated by pistons 11 ; and distributes steam alternately to opposite ends of the cylinder 6 through the passage 12. The auxiliary valve 13 works to and fro in the direction of the axis of the cylinders, over the back of the bridle 10, which is formed with steam and exhaust passages and distributes steam alternately to the pistons 11 through the passages 14, the effective area of which may be regulated by a valve. The auxiliary valve is actuated by the internal shoulder of a nut 19 on the piston-rod which comes into contact with a tappet 21 on the end of the valve stem, and with a sleeve 22 which is screwed on the stem and engages the valve by means of a pin-and-slot connection, so that it cannot turn in relation thereto. The upper end of the stem is screwed and locked in a tubular socket 29 slotted at the top to engage a cross-pin on the spindle 32, which passes out through a stuffing-box and is formed with a square end. By turning the spindle, the stem is screwed up or down through the nut in the valve and through the sleeve, but, as this has a thread of twice the pitch of the nut, the sleeve and the stem are moved to the same extent in opposite directions in relation to the valve. The socket 29 is of the same diameter as the sleeve 22, and the chamber 35 into which it works is put into communication with the upper part of the cylinder by the pipe 36 so that the steam pressures on the spindle and its sleeves are balanced.

Granted: 1905-05-09
Abstract: 10,670. Bottomley, J. F., Hutton, R. S., and Paget, A. May 9. Electric furnaces. -Resistance furnaces are used for the manufacture of articles of pure silica. A carbon tube a, Fig. 1, is embedded in quartz sand, and current passed through it for some time, so that it becomes incandescent and reduces the surrounding sand b to a plastic condition. The unfused sand r is allowed to escape through a door g, and the fused silica is then blown in a mould f by air introduced through a pipe d. Instead of the tube a, a carbon plate a, Fig. 8, may be employed, with a separate blowpipe j. In a modification, the sand is contained in a vessel of refractory material, and is heated by radiation from the heated carbon plate. In a further modification, the current is passed through the containing-vessel itself, which is made of carbon. The Provisional Specification states that an arc may be used instead of the electrically-heated carbon, but this is disclaimed in the Complete Specification.
