Patent GB-515199-A (GB)
Title: Improvements in or relating to echo sounding apparatus
IPC: G01S1/72
Filed: 1938-03-04
Abstract: 515,199. Echo-sounding apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and GAL- . WAY, H. March 4, 1938. No. 6890. [Class 118 (ii)] The transmitter is operated periodically and means are provided for allowing the receiver to operate indicating means at a different periodicity so that the time interval between these operations changes cyclically, the indicating means giving an' indication dependent on the time which has elapsed between a certain point in the cycle and the instant when the echo signal received by the receiver was able to operate the indicating means. An apertured disc 5 and a slotted disc 6 are rotated by a constant speed motor 8 the gearing 7 being such that for each rotation of disc 6, the disc 5 does not quite complete an integral number of revolutions. A switch, (not shown) is operated by a cam on disc 6 to close the transmitter circuit, a corresponding receiver operating the oscillograph 1 to a position where the light from the lamp 2 would pass to the photocell'4 if the slot and aperture coincided. Owing to the nature of the gearing, the aperture coincides with adjacent parts of the slot at each revolution of disc 6, the whole slot being "scanned" before the discs are restored to the same relative position corresponding to the beginning of the cycle. At some point inthis cycle, the light will pass to the photo-cell to operate the indicating apparatus, Fig. 4. Each rotation of cam 16 stops ratchet wheel 13 to raise a frame 12 carrying a film 11 on which is recorded depths in fathoms. Upon the cell being energized, a relay locks up and energizes magnet 22 to retract the driving pawl 13b, contact 19 having the same effect, if the cell is not energized, when the frame engages them. An elliptical sprocket 27 is rotated from the shaft of the disc 6 to reciprocate, once per four rotations of disc 6, platforms 17, 18 carrying a light source and photocell for reading the records. During the last reciprocation of the cycle the loudspeaker circuit is closed so that the relevant record is read and reproduced. The magnet 25 is then energized to retract pawl 13a and the circuit broken eventually by the fall of the frame opening contacts 20. The main switch to the apparatus is arranged so that it may only be opened at the end of the cycle. Instead of an aural indicator a mechanical counter, a monogrammic sign or indicator board having lamps selectively lighted may be used. The instrument can be converted into a two-range apparatus by using another pair of contacts operated by the cam on disc 6 and displaced from the first pair.

Title: Improvements relating to the temperature control of vapour phase chemical reactions
IPC: C01B3/44
Filed: 1942-05-21
Abstract: <PICT:0568913/IV/1> The temperature of vapour phase chemical reactions is controlled by maintaining in the reaction chamber 10 a dense suspension of a powdered material which may be catalytic or inert.  The reaction chamber is of uniform cross-section, and above it is a zone 17 of greater diameter in which suspended powder is disengaged from the gas and falls back into the reaction chamber. Any powder which is carried out of the zone 17 is separated in a cyclone 20 and returned to the reaction chamber.  Additional temperature control may be provided by a heat-exchange conduit 33 surrounding the reaction chamber.  The invention is illustrated as applied to the production of phthalic anhydride by oxidation of naphthalene, which is fed from hopper 1 to pipe 3 where it is melted and furnace 4 where it is vaporized.  The vapour is mixed with vanadium oxide catalyst and fed into the reaction chamber below distributing grid 11.  Oxygen or air is admitted at 16.  Other reactions to which the invention is applicable include hydrogenation, oxidation, chlorination, nitration, isomerization, polymerization, cracking, desulphurization, and the synthesis of methanol, phosgene and ammonia.

Filed: 1943-05-03
Abstract: 571,534. Towel delivery apparatus. DEHN, F. B. (Towlsaver, Inc.). May 3, 1943, No. 6962. [Class 18] Paper towelling carried on a core 4 in the form of a roll is dispensed through an opening D, Fig. 2, by actuation of a handle J, Figs. 1 and 2, the arrangement being such that after one rotation of the handle a dwell of predetermined duration is imposed before further delivery can take place. To effect this, a bar 30 is reciprocated vertically by the links 36, 39 and is latched in its uppermost position by a latch 23 on the bar engaging a stop 35 mounted on the casing. The upward movement of the bar raises a ball G, which, from its raised position, runs down a plane 45 on which baffles are placed, pin-table fashion, so that after a predeterminable time, it reaches a position in which it rests on latch 33 as shown. A slight rearward movement of handle J to an extent governed by pawl 17 releases latch 33 from contact with stop 35 and permits it to rotate about its pivot under the weight of ball G so that when feeding' movement of handle J is resumed, latch 33 no longer prevents its movement. A serrated cutting edge 14 is provided.
