Title: Recovery of chlorine from ferric chloride
Inventor: MILFORD KOLB KENNETH
IPC: C01G49/06
Filed: 1971-03-12
Abstract: Ferrc chloride (e.g. from the purification of Ti ores) is introduced into the upper chamber of a two chamber reactor, where it is heated to 550-700 degrees C in an inert gas (e.g. N2) under a pressure of 4-5 atm. until equilibrium between solid FeCl3 and its vapour is reached. Then the particulate solid material and the vapour are passed into the lower chamber of the reactor where an oxidising gas (air and/or O2) is introduced and FeCl3 is oxidised at 525-700 degrees C. A bed of inert refractory particles fills apart of the upper chamber and the lower chamber, it moves downwards together with FeCl3 and ensures a uniform distribution of heat. Free chlorine is withdrawn from the bottom of the apparatus; the recovery amounts to 95%.

Title: Rapier loom - in which weft threads are carried on vertical flexible tapes with reed and finger supports
Inventor: SPARLING ROBERT OXLEY
IPC: D03D47/00
Filed: 1973-02-14
Abstract: The shuttleless loom is generally of the type described in US 2,604,123, wherein the weft threads are carried on flexible tapes. These, however, are vertically disposed in the present method and thus move on their edges. They are supported on one side by the reed and on their other side by specially designed guide fingers. In order to ensure synchronisation between the tape feed and the lay of the loom, the former uses the same mechanism as that which rocks the lay. Thus the tape is fed in unison with the normal lay rocking motion. The arrangement allows a compact design for the loom and by mounting the tapes on their edges minimal friction is encountered during feeding. All of the present features may be employed to convert a conventional fly shuttle loom to a shuttleless one.

Title: Hearing aid with transistor amplifier - has automatic gain control with certain response and oscillation decay time
Inventor: EGGERT ALBERT
IPC: H03G3/30
Filed: 1973-10-26
Abstract: Means are provided for the response and for oscillation decay time control. The multistage transistor amplifier AGC is operated by the working point of a preamplifier transistor, or by a d.c. control voltage varying a negative feed-back.

Title: Long distance ski adapted for hill climbing - has pattern of steps on undersurface to resist reverse motion
Inventor: HINTERSEER THOMAS
IPC: A63C5/04
Filed: 1973-12-11
Abstract: the middle third of the undersurface of the ski is provided with a number of indentations which are arranged in four parallel longitudinal rows, these being two rows on either side of the central guiding groove. The indentations are bound by nearly semi-circular steps and the surface of the indentation slopes upwards to merge with the main ski surface. The radius of the step is slightly greater than half the distance between the staggered rows. The form and arrangement of the indentations reduces friction in forward motion and reduces noise to a minimum when the ski is used on hard snow.
