Title: A method for the purification of water
IPC: C02F1/64
Filed: 1936-12-17
Abstract: Drinking and industrial waters of all kinds are purified by filtration through basic-reacting dolomite.  Dolomite is calcined to convert magnesium carbonate into oxide without altering the calcium carbonate.  The treatment of the water is stated to neutralize the free carbon dioxide in the water, and to remove iron and manganese as well as chlorine and oxygen.  The process can be applied for the removal of lead and copper from drinking, industrial, and residual waters, and particularly for the removal of copper from water to which copper solution has been added as a bactericide.  Water can be sterilized by filtration through dolomite which has been impregnated with solutions of copper or silver salts.  The removal of oxygen and chlorine from water under treatment may be promoted by inserting plates of different metals in the filter bed of dolomite to serve as electrodes.  Reference has been directed by the Comptroller to Specification 3730/86, [Class 46].

Title: Process for preserving proteinaceous foodstuffs
IPC: A23K30/00
Filed: 1954-12-02
Abstract: Foodstuffs having high moisture and protein contents, e.g meat, fish, are preserved by reducing the undried food to small pieces, mixing with starch or a starch-containing flour, the proportion of the starch or flour being 40 per cent to 85 per cent by weight of the undried mixture, and drying the mixture. According to an example, 100 kg. minced lean meat was intimately mixed with 77 kg. pre-dried manioc flour.  The mixture was dried at 50-55 DEG  C., e.g. by exposure to the tropical sun, to reduce the moisture content to less than 15 per cent, thereby providing about 117 kg. of white powder free from obnoxious odour.  Fish may be heated before or after mixing, with warm air at 80 DEG  C. for several minutes to expel oil.

The drawing shows one section of track with a three-position signal 20B, controlled by track relay TB, which directly controls the home relay HB, of which armature 111 closes the circuit to the " caution " mechanism of the signal 20B, armature 126 in series with armature 122 of the advance section closes circuit of relay DB which controls the " clear " mechanism of signal 20B and the circuit to the ramp 12B, which includes battery B4B, contact 21, rail R', train apparatus, ramp 12B, and wire 100. In shunt to the train apparatus between the rail and the ramp is a relay 17B which is thus energized only when the ramp is energized and controls a contact 117 in the circuit of the " clear " mechanism of the signal which cannot be completed if the ramp is broken or removed. A closed circuit passing from end to end of the ramp includes the battery B4B resistance a and relay 160, the contact 105 of which controls the relay HB and therefore a broken ramp causes de-energization of the relay HB, putting the signal 20B to " stop " and the signal of the rear section to " caution."
