Abstract: 391,851. Hair combs ; hair-cutting appliances of safety-razor type. AGOSTINI, L., 3, Faubourg St. HonorÚ, Paris. Nov. 3, 1931, No. 30506. [Classes 30 and 131.] In a comb for cutting and thinning the hair and having a blade 2 disposed across the spaces between the teeth, the cutting edge of the blade is exposed at alternate spaces, or the spaces at which the cutting edge is exposed alternate with spaces at which cutting edges are exposed at a different distance from the ends of the teeth. The blade 2 may be straight or have saw teeth and may be mounted in a slot in the comb and secured by screws 4 in holes 6, Fig. 1. Alternate spaces are prolonged, as at 5, to expose the cutting edge. Alternative holes 6 may be provided to allow for longitudinal adjustment of the blade. The inner ends of the spaces may have an angular form. The blade may have two parts, a straight blade 7b, Fig. 5, being exposed in the longer spaces, and a rectangularly toothed blade 7 exposed in the shorter spaces. The blades 7, 7b may be integral or separate. The comb may have sets of fine and coarse teeth with separate blades for the respective sets.

Title: Urea synthesis process
IPC: C07C273/04
Filed: 1963-08-01
Abstract: In a process of urea synthesis from ammonia and carbon dioxide at elevated temperature and pressure, wherein the unconverted reactants are recirculated as an off-gas, the off-gas being formed at least in part by heating the aqueous urea product stream to decompose ammonium carbamate, the off-gas adiabatically compressed to synthesis pressure and thereby heated to an elevated temperature, compressed input streams of ammonia and carbon dioxide are admixed to the hot compressed off-gas to quench said stream and the combined reacting stream is cooled in heat exchange with water.  The formation of the off-gas may take place in two or more separate pressure reduction stages.  The excess heat removed in the heat exchange is preferably recovered as high pressure steam and may be employed to provide power for the adiabatic compression.  The example described with reference to a flow sheet (not shown) employs a rotary compressor and two stage pressure reduction to recover off-gas and final aqueous scrubbing with scrub liquor recirculation.

Recording and play-back apparatus for teaching purposes including an endless tape 12 associated with a number of heads 16 arranged in a line transverse to the tape is characterized in that a first group of the heads scan a lesson recorded on respective tracks and a second group of the heads are arranged to record sounds on adjacent tracks. The lesson is first recorded on to the tape loop 12 from a master tape 4, both tapes being driven from a common capstan 9 by means of separately engageable pinch rollers 7, 11. The loop 12 is first wound to a " start " mark, and each sentence of the lesson is then recorded on to a separate track, e.g. A. . . E, Fig. 3, each sentence commencing at the start mark. The drive to the master tape may now be disengaged, and students, e.g. 32, 40 may select any of the sentences by means of switches 28, 39. Having listened to the selected sentence, the student may then record his own version of it on one of the tracks F ... J, and subsequently play it back to compare it with the original. At the end of a practice period the loop 12 is removed from the machine, and the tape 4 fed round rollers 13 past the head assembly 16 so that the students may record direct on to the tape 4. The teacher's comments may also be recorded for subsequent play-back to the students, either on additional tracks or on part of the tracks F . . . J.

Filed: 1927-11-18
Abstract: 280,947. Silica Gel Corporation, (Assignees of Miller, E. B., and Connolly, G. C.). Nov. 19, 1926, [Convention date]. Purifying processes.-Gases are freed from sulphur compounds by treatment with air or other oxidant in presence of a solid adsorbent carrying a metal oxide. The adsorbent is preferably a highly porous gel; suitable materials are silica gel impregnated with about 1 per cent of ferric or cupric oxide or both. The adsorbent may be mixed in suspension in a current of the gas mixture or the latter may be passed through layers of the adsorbent; in the latter case two layers are conveniently used heated respectively to 200-210‹ C. and 185-200‹ C. Where organic sulphur compounds are present a preliminary treatment, e.g. 450‹ C., is employed to convert these into hydrogen sulphide, which is oxidized to sulphur and water in the second stage. Sulphur dioxide formed may be removed by means of ammonia solution. Specifications 25976/06, [Class 90, Non-metallic elements], and 255,864, [Class 1 (i), Chemical processes &c.], are referred to.
