Title: Drying and distilling peat in situ
IPC: C10F5/06
Filed: 1943-12-25
Abstract: 574,044. Electric heating. HEYL. G. E. Dec. 25, 1943, No. 21691. [Class 39 (iii)] [Also in Groups XII and XXI] Carbonaceous deposits in the earth such as peat or coal, are heated by forcing a metal casing round a mass of the deposit on the site thereof and forcing rod-shaped electric heaters into the enclosed mass to dry or distil it. The casing is a bell or caisson with one closed and one open end. Rod-shaped electric heaters with external radial fins are passed through holes in the cover of the casing, the resistance elements comprising carbon rods or helically wound wire. The mass is compressed during heating by downward pressure on the bell, which cuts into the deposit, or by the closed end of the bell sliding as a piston in the casing. Vapours are led off or condensed. The casing may be the liner of a scoop of a mechanical excavator. When full, the liner is removed from the scoop by a crane and is closed by a cover for heating. The liner has a heat-insulated jacket comprising two sleeves, each closed at one end and fitting over the liner. After removal of top growth, ditches are cut in a peat field in rows at right-angles and a square bell is placed over the block so formed. A roller shutter in a groove at the base of the bell may be pulled by wire ropes in grooves across the bell to cut off the peat block. Manhole lids in the top of the bell are removed and some peat is excavated to allow insertion of the heaters. For deposits too hard for the insertion of the bell by pressure, e.g., coal, channels are cut to receive the edge of the bell. At 400‹C. hard carbon blocks are formed from peat, pitch if necessary being forced into the bell, which may have an internal heat-insulating layer of asbestos cement. Vapours may be retained in the bell and cracked to form carbon.

In a gramophone pick-up for use with both long playing and standard records, two styli arranged for alternate use by rotating the pick-up head are associated with separate piezo-electric transducers. As shown in Figs. 3 and 5, the separate transducers 37, 39 are located with their axes at right angles within a pick-up head formed by two complementary ceramic halfcasings 11, 12 and are positioned by hard rubber pads 58, 59. The transducers may comprise rochelle salt or ceramic bimorph bender units which are insulated at their outer ends and fitted with U-shaped metal saddles 62. Each stylus arm 65 is force-fitted at its end remote from stylus 68 in a resilient rubber block 49, and engages a V-shaped slot 63 in the adjacent saddle. A resilient pad 70 protects each crystal unit from damage by excessive stylus movement. Conducting strips 71, 79<1> are clamped between the opposite outer electrodes of each crystal and the positioning pads 58, 59. Strips 71 provide electrical connection to spring- loaded balls 73, Fig. 2, which are located in transverse recesses 44 in the casing halves and have partial entry into mounting sockets 28, 29. Strips 79 on the other hand are each connected to a springy contact 75, 75<1> located in a recess 25 in the assembled casing, the contacts being located in position by cranked tail portions which engage webs 41 in the half-casings 11, 12. When assembled the casing portions are clamped by through-bolts 14, Fig. 7, and the head is detachably fitted to a rotatable metal carrier 82 on a tubular pick-up arm 81 by engagement of sockets 27, 28, 29, 30 with four metal carrier pins 90: As the balls 73 engage two of the pins, a common circuit through the carrier is provided for one electrode of each transducer. An insulated lead 99 in the pick-up arm is connected through an insulator 97 to an offset contact 98 which engages one or the other of contacts 75, 751 according to which transducer is in the operative position. Thus only one transducer at a time is connected to lead 99. Rotational movement of the carrier is limited to an angle of 180 degrees by a pin 102 and a semi-circular slot 101. Protection of the stylus assemblies is provided by extended and bifurcated carrier arms 87, 88. A further guard may be mounted on the pick-up arm which extends over the upper stylus assembly to afford additional protection. Specification 712,241 is referred to in the Provisional Specification.
