IPC: H04M9/00
Filed: 1967-06-16
Abstract: 1,232,974. Loud - speaking telephones. DOWNHAM ELECTRONICS Ltd. 13 June, 1968 [16 June, 1967], No. 27952/67. Heading H4R. A control system in a voice switched loudspeaking telephone comprises first and second variable attenuators, one each in the transmitting and the receiving channel, controlled photo-electrically such that the presence of a signal in any channel reduces the attenuation in that channel and increases the attenuation in the other channel. As shown, the attenuators are located between the hybrid and the transmitting and receiving amplifiers respectively and each comprise a resistor R12 (or R28) shunted by a photo-cell PC1 (or PC2) and isolated by transistors VT3 and VT4 (or VT7 and VT8). The photo-cells PC1 and PC2 are each controlled by a lamp LP2 or LP1 respectively connected in the outputs of a comparator comprising transistors VT13 to VT16. In the quiescent condition the attenuators provide equal attenuation. A signal taken from the emitter of transistor VT4 is amplified at VT12 and rectified and applied to the comparator via diodes D1 and D2 in such a manner that the base of VT14 is driven positive and the base of VT15 is driven negative. Thus transistors VT13 and VT14 conduct further and transistors VT15 and VT16 conduct less increasing the brightness of lamp LP1 and reducing that of lamp LP2. The resistance of photo-cell PC2 is thus decreased increasing the attenuation in the receiving channel, while the resistance of the photo-cell PC2 increases, decreasing the attenuation in the transmitting channel. If an incoming signal is detected at the emitter of the transistor VT7 in the receiving channel this is amplified by transistors VT17 and VT18. Diodes D3 and D4 rectify this signal which is applied to the comparator in a sense opposite to that of the outgoing signal. A circuit comprising transistors VT103 to VT106 and associated components including a capacitor C103 amplifies and extends the duration of an incoming signal, and is used to make the comparator more sensitive to signals incoming from the remote telephone, this being necessary if the remote telephone is also of the loud-speaker type.

Abstract: 1,250,413. Making bolts; rolling screw threads. REED ROLLED THREAD DIE CO. 30 Jan., 1969 [31 Jan., 1968; 3 May, 1968], No. 5218/69. Headings B3A and B3M. [Also in Division F2]  A self-locking screw (see Heading F2H) is made by rolling a cylindrical workpiece between thread forming dies to form a thread on the workpiece and deforming a flank of at least a part of at least one turn of the thread between the crest and root thereof to form an arcuate rib 62 of substantially triangular cross-section parallel to the crest and diverging outwardly beyond the flank leaving a cavity 70 of corresponding shape and volume to the rib. The tool 58 used to form the rib is preferably incorporated into the discharge end of one of the dies used to form the thread, Fig. 5. The other die has an unthreaded portion 82, Fig. 6, for producing ribs of more than 180 degrees of a thread so that the rib is not wiped out by the further action of the other die. This other die also has the threads at its discharge end relieved away from the one die so that the leading edge of a rib is first engaged by an unrelieved wall of a thread in the other die to bend it back into the flank of the screw thread and then as thread rolling continues the screw is moved away from said one die causing the trailing end of the rib to be made shallower and taper back into the flank of the screw thread, Figs. 19 to 25 (not shown).

Abstract: 1,256,737. Tris-(hydroxymethyl) nitromethane. COMMERCIAL SOLVENTS CORP. 13 March, 1969 [13 March, 1968], No. 13353/69. Heading C2C. Tris-(hydroxymethyl) nitromethane is produced in a continuous process by passing nitromethane and formaldehyde in a molar ratio of 1: 3, together with an alkaline catalyst and, if necessary, water, to form an aqueous reaction mixture in a reaction zone, the amount of catalyst being sufficient to maintain the pH of the mixture at 7À8-8À3, and maintaining the temperature between 50‹ and 65‹ C. during the residence time in the zone of from 8 to 12 minutes. The aqueous solution of tris-(hydroxymethyl) nitromethane thus obtained is then removed from the reaction zone and may be then reduced to give tris-(hydroxymethyl) aminomethane. Specified alkaline catalysts are hydroxides and carbonates of sodium and potassium, hydroxides and oxides of calcium and barium, and organic tertiary amines, particularly trimethylamine, and the inorganic catalysts are subsequently removed from the reaction mixture, e.g. by absorption on an ionexchange column or by precipitation. Tertiary amines may be separated, e.g., by distillation, at a later stage, e.g. after reduction. The formaldehyde may be supplied in gaseous or aqueous phase or as paraformaldehyde.

Abstract: 1,257,345. Liquid-ring pumps. NASH ENG. CO. Jan.27, 1969 [May 17, 1968], No.4522/69. Heading F1C. A liquid-ring pump has passages 78, 80, Fig. 2, through which liquid from the ring passes to annular chambers 72, 74. By suitably selecting the angular location of the passages, a specific pressure is set up in the chambers. The liquid in the chamber 74 cools the shaft seal 44 and passes through a passage 82 into a central chamber 58 where it seals the running clearance 59. The chamber 72 communicates with the pump discharge 22 via a passage 76 and a reservoir chamber 26. The arrangement may be such that the pressure in the chamber 72 exceeds the pump discharge pressure at low compression ratios to cause some of the sealant liquid to be delivered to the various running clearances and some to be exhausted to the pump discharge, and is less than the pump discharge pressure at high compression ratios to cause an increase in the sealant liquid delivered to the running clearances. A one-way valve may be installed to prevent sealant liquid flowing from the chambers 72, 74 to the ring during high compression ratio operation. The pressures in chambers 72, 74, 58 are substantially equalized to balance axial thrust. The width of the rotor chamber can be varied by shims 18. Sealant liquid is delivered through conduit 28 to inlet part 70. In an alternative embodiment, Fig. 4 (not shown), the sealant liquid is delivered through a conduit (28<SP>1</SP>) coaxial with the shaft and communicating directly with the central chamber (58<SP>1</SP>).

Title: Container for liquids and its manufacture
IPC: B21D51/00
Filed: 1994-06-27
Abstract: The pallet container (1) for liquids has an exchangeable inner container (2) made of sheet metal, an outer casing (6) of latticework and a pallet (9) which is designed as a bottom tray (10) and receives the bottom (16), designed as a drainage bottom, of the inner container in a positive-locking manner. The inner container (2) of sheet metal, preferably of dual-walled design, is welded together from a casing (11), a bottom part (12) and a lid (13). To produce the inner container, a rectangular sheet-metal blank is bent to form a tubular body whose abutting edges are welded longitudinally. The tubular body is stretched to form a casing of rectangular cross-section. A circumferential bead with a V-shaped cross-section is then moulded in each case into the two end regions of the casing with spacing from its edges which are subsequently trimmed. The deep-drawn, tray-shaped bottom part is then fitted precisely with a bent edge onto or attached to the outer flank of the one bead of the casing, and the bottom part is fixed to the casing. The lid is mounted on the casing in the same manner. The bottom part and the lid are welded to the casing. To form a smooth transition between the casing and bottom part on the one hand and the casing and lid on the other hand, the transition regions between the casing and the bottom part and the casing and the lid are widened by applying pressure to the inner container inserted in a supporting mould. <IMAGE>
