Title: Improvements in and relating to telephone installations
IPC: B03B5/24
Filed: 1936-08-20
Abstract: 467,385. Automatic exchange systems. TELEFONBAU UND NORMALZEIT AKT.- GES. Aug. 20, 1936, No. 22977. Convention date, Feb. 12. [Class 40 (iv)] In a system employing alternating current loop working over junctions, the repeaters at either end of the junction are arranged for leg working within the exchanges, impulses and other forward signals being sent over the a wire and backward signals being sent over the b wire. Upon seizure of the repeater U1, relay 1C energizes over the c wire and 1S transmits a calling impulse over the junction during the slow operating period of IU. Relays 2E, 2A, 2C respond and the last relay locks and connects up H, 3C, the latter seizing the selector. Impulses over the a wire are repeated by 1A, 1S over the junction and thence by 2E, 2A over the a wire to 3A. Upon reply of the called party, relay 3Y connects up K over the b wire and an impulse is sent over the junction during the slow operating period of L. Relays 1E, 1Y respond, connecting battery to the b wire, and on the relapse of 1E, 1X energizes and holds 1Y. The relapse of 3Y when, the called party hangs up, results in an impulse being sent during the release period of L, bringing about the release of 1X, 1Y and the removal of battery from the b wire. When the calling party hangs up, 1C falls back and an impulse is sent as before and 2A responds and shortcircuits 2C, whereupon 3C falls back and releases the selector. Relay K energizes over the b wire until the selector reaches normal, so that two impulses are sent back, the first operating 1Y, which opens the energizing circuit of 1C and the second disconnecting 1Y to render the repeater available. To prevent interference between impulses in the two directions over the junction, relay 1S opens the circuits of 1X, 1Y, and relay 2V controlled by 2A opens the b wire at the repeater U2. In a modification, relay L is such that its release period is greater than its operating period, so that a longer impulse is sent when the b wire at the repeater U2 is opened. This results in the energization of a slow-operating relay at the repeater U1 which disconnects 1X, 1Y.

Classes 64(1) and 64(3) A heat exchanger comprises an annular bank of parallel tubes 36 around a venturi tube 19 which has a tubular extension 20. Hot gases generated or received in a chamber 12 flow through a nozzle 18 into the venturi tube, and entrain hot gases which have already traversed the tubes 36. The gases mix in the tube 20, and then flow in the reverse direction between the tubes 36. Some of the hot gases escape through annular passages formed by tubes 38 around the tubes 36, to a chamber 31 with an exhaust outlet 15. Air to be heated flows from an inlet 14 through a chamber 23 an annular passage formed by a cylinder 21, and a header 27, to the tubes 36, header 32, and outlet 11. In the form shown, the chamber 12 is a combustion chamber. In a modification in which the chamber 12 receives hot gases at atmospheric pressure from a cupola or other furnace, an exhaust pump supplies suction to the exhaust gas outlet 15.

Abstract: 1385106 Control of several D.C. motors TOKYO SHIBAURA ELECTRIC CO Ltd 19 May 1972 [25 May 1971 (2)] 23665/72 Heading H2J A control system for the D.C. driving motors A1, F1 ... A4, F4 of an electric vehicle comprises a thyristor chopper CH which controls the voltage supplied from a pantograph PG, diodes D, DR, DF, and a master controller MC for the chopper CH and electromagnetic contactors K, KR, KF1, KF2, the controller providing (K, KR closed) series connection of the armatures A1 ... A4 and field windings F1-F4 in the low speed traction mode under the control of the chopper CH, shunt connection of the armatures A1-A4 and field windings F1-F4 in the high speed traction mode (K open, KF 1 KF 2  closed), with the windings F1-F4 controlled by the chopper, and regenerative braking in which for high speeds, the motors operate as shunt generators (K, KR open, KF 1 KF 2  closed) with self or separately excited field windings controlled by the chopper and for low speeds, the motors operate as "series generators" controlled by the chopper, the latter condition being obtained by closing contactor K, with KR open and KF1, KF2 closed, and the resultant circuit being stated to produce energization of the field windings by the armature current. The embodiment shown provides self-excitation of the shunt generators in the braking mode, changes to "series generator" operation under the control of a speed signal obtained from a tachogenerator G, and includes a current sensor CT which controls the chopper CH to maintain the armature current at a desired value corresponding to the rating of the motors. Another embodiment, Fig. 4 (not shown), provides excitation of the shunt generators from the pantograph PG and uses the voltage of one of the armatures as the speed signal. The diode DR is omitted, its function being performed by the diode D which is in parallel with the contactor KR through two additional contactors (KC1, KC2). A further such contactor (KC3) provides, with (KCl), the separate excitation feature. A prior art control system is discussed, Figs. 1 and 2 (not shown).

In a hand tool, e.g. gardening shears, pruners and wire cutters, comprising a pair of handles to which are attached a pair of tangs, the tangs being pivotally connected by a pivot assembly, the handles 10 are formed of a synthetic plastic e.g. polypropylene and are each provided, extending from a shoulder 12 thereon, with a passage for the reception of a tang 14, Fig. 8, of a blade 15, the passage being eccentrically formed in the handle, as shown in Figs. 3 and 4, and the handle being sufficiently deformable under heat and/or pressure for either of the tangs to be insertable in the passage during manufacture of the tool. In making the hand tool, the handle is first heated to soften the synthetic plastic. It is then mounted on a jig which has a protrusion which fits closely into a bore 22 in the handle. The tang of the blade is then forced into the passage in the handle. A rivet 20 on the handle will register with a hole 19 in the tang so that the handle can be riveted to the tang. After the assembled handle and blade have been removed from the jig, the bore 22 is closed by a plug 24. When the blade tangs have been forced into their respective handles, the tangs are fastened together by a pivot assembly which is located in the tang holes 17 and in the well or wells formed by the handle holes 18. Instead of applying heat to the handle, the heat remaining in the moulding may be utilized.
