Title: Mechanism for operating signal systems in mines
IPC: B66B19/06
Filed: 1919-09-13
Abstract: 149,851. Frew, J. Sept. 13, 1919. Mechanical telegraphs; mine and colliery signals.-In mechanical telegraphs of the kind used for mine signalling, a full stroke of the signalling-lever is ensured by means of a ratchet device which prevents return of the lever until the stroke has been completed, whereupon the ratchet is put out of engagement. The ratchet device may be applied to the wire, with modification, or to the lever. As described, the lever 1 carries a detent 2 engaging a ratchet 3 which allows downward movement of the lever, but prevents return movement until the stroke is completed. The ratchet is carried bv a plate 10 provided with gates 11, 12 and mounted on guides 4. The plate is urged towards the lever by springs 6. The lever carries a pivoted member 7 with a roller 9. During downward movement of the lever, the member 7 takes the position shown in Fig. 3, and runs over the plate 10 without displacing it. At the completion of the downward stroke, the roller 9 enters the gate 12 and the member 7 is reversed to the position shown in Fig. 5. In this position the roller bears on the plate and displaces it to the right so that the ratchet is clear of the detent. At the upper end of the stroke, the roller enters the gate 11. Reversal of the member 7 is caused by contact with the edge of the gate opening. Lateral movement of the lever is prevented bya guide 13.

Title: Process for producing a formed-in-place earpiece
IPC: H04R25/02
Filed: 1973-05-11
Abstract: 1402238 Earpieces MARION HEALTH & SAFETY Inc 11 May 1973 [17 May 1972] 22628/73 Heading H4J A formed-in-place personalized earpiece of resilient, non-irritating, cured, synthetic elastomer has an apertured protuberance which extends into and conforms to the person's ear canal when the ear canal is stretched and enlarged. Such an earpiece prevents unwanted sounds being transmitted to the ear. The earpiece 11 (Fig. 11) consists of an outer part 2 which fits into and is held by the front fold 40 (Fig. 6) of the outer ear and a protuberance 4 which fits into the ear canal. A sound transmitting passage 5 leads from a connector ring 7 to the protuberance 4. The protuberance 4 is sufficiently short so that it does not extend into the ear to touch skin unsupported by cartilage. Ring 7 may be of brass but is preferably of pre-moulded silicone rubber which is chemically bonded to the earpiece, also made of silicone rubber, during caring of the latter. Curing preferably takes place at just above room temperature. The outer surface of the ring 7 or receiver transducer preferably stands out from the body of the earpiece. In moulding the earpiece, a disc (36), Fig. 2 (not shown), of a putty-like polysiloxane compound is rolled around a coring tube 38 (see Fig. 6) and formed into a blunt, tapered cone (40), Fig. 5 (not shown). The entrance to the ear canal is enlarged by pulling on the outer ear, and the tapered end of the cone (40) is inserted into the ear canal. The remaining compound is folded towards the ear and additional putty is moulded around the tube 38 in the area 48 (Fig. 6) sufficient to engage the fold 44 of the ear. Coring tube 38 is centred. A connector ring 7 (Fig. 10) fitted into a finishing plate 50 is pushed into the compound so that the ring 7 is embedded and the inner surface of the plate 50 is made to press the composition and give it a flat surface. After the earpiece has set, the combination is removed from the ear and the finishing plate 50, of acrylic or styrene resin which does not adhere to the putty, is removed. After trimming any edges, the earpiece may be dipped in a finish coating. Finally the coring form 38, also of material non-adherent to the putty, is pulled out and leaves a sound passage of correct size. The silicone composition may be kept in a flexible bag containing catalyst in a rupturable pouch prior to moulding.
Patent GB-842946-A (GB)
Title: Method of producing copper metal powder
IPC: B22F9/26
Filed: 1958-07-15
Abstract: Copper metal powder is produced from aqueous solutions or slurries containing salts of copper with salts of nickel and/or cobalt by reducing with a sulphur free reducing gas at elevated temperature and pressure, the method characterized by precipitating all the copper from a first batch of solution, some cobalt and nickel coating the copper particles, heating the precipitate in a second batch of solution between 90 DEG C. and the temperature at which the reduction is carried out so as to redissolve cobalt and nickel, again reducing until the solution is substantially depleted of dissolved copper, the reduction being thus carried out in a cyclic series of reducing steps in which the precipitate from the previous reduction is heated in fresh solution which is then reduced and discharged, and the precipitate therefrom carried forward to the suceeding reduction, until a final step in which the reduction of copper is left incomplete so that nickel and cobalt are not precipitated and the copper powder of high purity separated from the liquid.  The last solution from which copper has not been completely removed may be passed to a succeeding cycle of reducing reactions.  The fresh solution subjected to the reducing reaction contains at least 1.9 gram mols of free ammonia per gram atom of copper plus nickel and cobalt.  A preferred temperature range is 120-270 DEG C. and a partial pressure of reducing gas from 13 to 26 atmospheres.
