IPC: B41B11/00
Filed: 1928-12-21
Abstract: 303,744. Rostock, O., (Assignee of Muller, G.), and Claussen, J. Jan. 7, 1928, [Convention date]. Cleaning matrices.-In apparatus for cleaning matrices by means of brushes, to which benzine is supplied, matrices are placed in a pile in a feed-passage, and have their side edges cleaned by brushes while passing therethrough, the matrices being then raised one by one between brushes, which clean their broad faces, and being then delivered by a rotary drying device, to a collector, by which they are again arranged in a pile. A pile of matrices 44 is pushed forwards in a feed-passage by a slide 3, which is drawn back by hand and is advanced by a spring. The slide carries the matrices past four brushes 8, 9, 10, which clean their edges, and presses them against the wall of a vertical cleaning-passage 14. They are then raised singly by a pusher 15, operated by a hand-crank, and pass between adjustable, brushes 22, 23, and through a stripping-device 24, having tongues of rubber &c., by which any cleaning material still adhering is removed. Benzine is supplied from a tank to the brushes through openings 39. The matrices next pass between travelling felt drying-bands 25, 26, and are delivered to a collector 33. The collector comprises inclined guide-rails 34, at the end of which is an) augle-iron 37, on to which the matrices slide, when it is withdrawn by means of a handle 36.

Abstract: 1,244,242. Well pump, hydraulic apparatus. SOULE STEAM FEED WORKS and J. M. LAWSON. July 28, 1969, No.37836/69. Headings F1A and F1P A well pump operating unit comprises a weighted carriage guided by a tower 19 and connected to a pump rod 17 by a rope 113, 115 passing round pulleys 101, 107 on the carriage and pulleys 81, (83) Fig.2 (not shown), 93, 95, 125, 127 on the tower, the carriage being raised and lowered by a hydraulic piston and cylinder assembly. The carriage 39 is connected by a gimbal assembly 169 to the cylinder 167 slidable on a piston 173 having a piston rod 171 pivoted to the tower 19. The piston rod has axial bores 270, 274, Fig.6, opening adjacent the piston into the cylinder chambers 175, 177, and connected to a variable displacement reversible pump 227 by lines 269, 275 respectively.

A fluid reservoir 31 mounted at the upper end of the tower 19 comprises three inter-connected tanks 201, 203, 205, and fluid is drawn from tank 203 by a charge pump 279 which feeds the pump 227 via a non-return valve 301 or 303, the pump 227 feeding the fluid to one of the cylinder chambers 175, 177 fluid being returned to tank 201 from the other of the cylinder chambers 175, 177 via a conduit 269 or 275, a shuttle valve 311, a low-pressure relief valve 315 and a conduit 317. The valve 311 also connects a high-pressure relief valve 313 to whichever of the conduits 269, 275 is at high-pressure. A check valve 281 in conduit 269 is connected to conduit 275 and prevents the escape of fluid from the chamber 175 if the pressure in conduit 269 suddenly drops (e.g. in the event of the pump rod 17 or cable breaking). The resultant high-pressure in conduit 269 then actuates a switch 285 to stop the motor 209.

Title: Transistor circuits et de traction including an electrochemical storage device
IPC: H02J9/00
Filed: 1970-08-06
Abstract: 1318060 Battery charging circuits; standby supply circuits SOC DES ACCUMULATEURS FIXES ET DE TRACTION 6 Aug 1970 [7 Aug 1969] 38074/70 Heading H2H [Also in Division H3] A circuit for charging a standby battery Ba comprises a resistor Rs in the discharge circuit of the battery and a transistor stage T 3 , T 4  which allows a charging current to flow through a cell B 6  used as a memory, the discharge of the cell being used to time the switching from a high charge rate to a low charge rate of the battery Ba when a main power supply U returns. When the main supply U is present the battery Ba is charged by the output of a diode bridge rectifier D 1 -D 4 . On failure of the main supply a contactor RO is de-energized so that the battery Ba supplies a load such as emergency lights connected between terminals A, D via a contact ro 1 . The voltage developed across the resistor Rs switches on the transistor T 4  so that the battery Ba also charges the cell Bb. When the mains supply returns, the contact ro 1  opens and a contact ro 2  closes thus enabling the cell Bb to discharge through resistors R 3 , R 4 . A transistor T 1  is therefore switched on which in turn switches on a transistor T 2  thereby energizing a relay Ra and closing contacts ra to connect a resistor R 2  in parallel with a resistor R 1 . A high charging current therefore flows through the battery Ba until the cell Bb becomes discharged thereby switching off the transistor T 1  and opening the contacts ra. The charging of the battery Ba then continues with a lower charging current.

Abstract: 369,278. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. and BAKER, J. H. E., Columbia House, Aldwych, London. Dec. 18, 1930, No. 38167. [Class 40 (iv).] In a system using two-motion selectors with common control circuits the difficulty that if a switch is released while the control circuit is busy busy potential from the control circuit may delay the release of the preceding switch is avoided either by providing separate testing- in and holding wires, Fig. 1 and Fig. 5 (not shown), or by arranging that when a switch is released and the control circuit is busy the combined test and hold wire is disconnected from busy potential for a period just sufficient to allow the hold relay at the preceding stage to be released, Figs. 2 and 3. In a further arrangement, Fig. 4, described only in the Provisional Specification, busy potential is disconnected from the hold wire during the whole of the release time of the switch. Systems with separate test and holding wires. As shown, Fig. 1, an idle switch is characterized by absence of ground on the wire T. When the preceding switch switches through, KS connects up the control circuit in which A, B, C pull up. A repeats the digit to the vertical magnet through C which at the end of the digit falls back to initiate interaction between the rotary magnet and the stepping relay G. When an idle line is reached, H is no longer short-circuited and energizes HS which switches through and releases the control circuit. In the other system, Fig. 5 (not shown), an idle switch is characterized by the presence of battery the switch being controlled similarly to that shown in Fig. 4. Systems in which a combined test and hold wire T is momentarily disconnected on release. As shown, Figs. 2 and 3, an idle switch is characterized by absence of ground. The associating relay KS is energized in series with the common impulse relay A and locked by B. Selection proceeds as in the system described above. When the switch is released, HS falls and in the system shown in Fig. 2, the incoming test and holding wire is momentarily disconnected but is grounded shortly afterwards by a contact of the release magnet ZS. In the system shown in Fig. 3, ground is maintained on the test and holding wire by the off-normal springs NS and when these change over, the wire is disconnected for an instant equal to the release time of the release magnet. System in which a combined test and holding wire is disconnected during the whole release time of the switch, Fig. 4. In this system an idle switch is characterized by the presence of battery. The switch is controlled as in the systems described above except that hunting is stopped by a test relay P which pulls up over the idle battery, shunts its high resistance winding and energizes H which short-circuits the other winding of P and energizes HS which switches through. On release, the test and holding wire remains disconnected until the switch is in its normal position and the release magnet has fallen back.
