Title: Improvements in or relating to battery charging systems
IPC: H02J7/36
Filed: 1920-03-03
Abstract: 144,611. Automatic Telephone Manufacturing Co., (Assignees of Obergfell, H. F.). June 11, 1919, [Convention date]. Regulation, automatic systems and apparatus for; systems of charging and discharging galvanic batteries.-The voltage across bus-bars D, E connected to a consumption device such as a telephone system supplied from a battery B, is maintained constant by opposing cells C, automatically switched in or out of series with the battery as the voltage rises or falls beyond certain limits. Assuming the battery to be on charge from the mains X, Y and the voltage rises beyond the allowed limit. The voltage coil 8 connected across the bars D, E attracts its armature 12 and closes a circuit through the relay coil 14. The armatures 19, 24 are attracted to open the circuit through the coil 8, close a holding circuit from the battery b through the coil 14 and connect a motor M and its field winding 6 to a battery b<1>. The motor turns the arm 4 of a regulating switch to cut in one of the cells C. On the spindle carrying the arm 4 a cam disk 7 is mounted, the cam controlling pairs of contacts 26, 27, so that the motor has to make sufficient revolutions to turn the arm 4 from one switch contact to the next. During this movement, the holding-circuit for the coil 14 is maintained through the contacts 26, its original circuit being broken at the contacts 18. When the arm and disk 7 have moved through one step, the contacts 26, 27 return to the position shown, the motor stops, and the relay 14 is de-energized; the circuit through the voltage coil 8 is made again ready to act if another cell is to be switched in. When the arm 4 reaches the last cell contact, or the last but one, a circuit is closed through the coil 31 of the charge switch F and the switch is moved up to stop charging. If now the voltage across the bars falls, the voltage coil 9 acts with the relay coil 22 to energize the motor and its field winding 5 to move the switch back and cut out the cells C. The disk 7 controls the working as before. As the last cells C are being cut out, a circuit is completed through the coil 34 of the charging-switch F, and charging is re-established. To prevent the motor from turning, the switch arm 4 between the end contacts, the disk 7 carries a pin 53, which in limiting positions opens contacts 15 and 16 or 16 and 17 to break the circuit of the relay coils 14 and 22. To prevent the arm 4 from short-circuiting one of the cells C, when it bridges adjacent contacts, it carries a contacting end consisting of low-resistance carbon 50, Fig. 2, and two insets 51 of high-resistance carbon.

Abstract: 470,194. Endless chain conveyers. ENFIELD CYCLE CO., Ltd., and GUISE, H. T. March 5, 1936, No. 6615. [Class 78 (i)] In apparatus for cleaning or degreasing metallic articles by dipping them into a series of baths, the articles are conveyed from bath to bath by a horizontal conveyer system, and are dipped into and removed from the various liquids and/or gases by vertically slidable elements without any lateral movement of the articles within the baths. The articles to be treated are hung on bars f which are supported by members d<1> on pairs of parallel chains c, d arranged over the baths a, b. When a bar reaches the position c<1>, it is lowered into supports e<1> on the vertically slidable members e which are then in their highest position, and are about to be engaged by catch members g<1> on the chain g which effects the downward movement. At the conclusion of this movement the article is suspended in the bath for a predetermined period. When this period has expired catch members h<1> on the elevating chain h engage projections e<3> on the members e and raise them. Members d<1> on the next pair of chains d remove the bars f from the supports e and transfer them to the next member e. The catches g<1>, h<1> are controlled by levers j, k actuated by cams l, m which are driven slowly by worm gearing. Catches i<1> which hold the slides in the raised position are disengaged by the catches g<1>. The slides are connected to counterweights e<2>.

IPC: D21F9/04
Filed: 1962-02-21
Abstract: 1,002,254. Making paper. SANDY HILL IRON & BRASS WORKS. Feb. 21,1962, No. 6650/62. Heading D2A. The paper making machine has a stock receiving chamber 26 in which is mounted a pond regulator 60 to define a passageway 80 through which slurry is delivered to a foraminous cylindrical shell 10. The setting of the pond regulator 60 is adjustable to allow variation of the crosssection of the outlet on to the shell 10. The chamber 26 and regulator 60 also define between them a rearwardly extending overflow passage that is associated with a flexible membraneous sealing means 104, Fig. 2, or 130, Fig. 3 (not shown) to allow of a pressurization of the stock within the passageway 80. An endless forming wire 11 passes around the shell 10 and a return roll 17 and receives stock at the upper rising quadrant of rotation of the shell 10 to form a web on the wire 11, there being suction means 112,114,118 within the shell 10 for draining water out of the web. A pick up felt 13 removes the web from the wire 11 at a point where the wire has left the surface of the shell 10 to go to the return roller 17. A perforated holey roll 102 supplies stock to the passageway 80. Excess stock flows into an overflow chamber 96 from which it may escape via a drain sump 98 for recirculation; and stock passing over the top of the wall 62 and into the pond regulator 60 escapes via a drain opening 76. In Fig. 3 (not shown) the overflow chamber 96 is closed by a flexible member 130. The level L in the chamber 96 is maintained constant by control means 132 connected to valve means 134 in a manner discharging excess air pressure from the chamber 96, excess stock being discharged into a container 138 by a flow meter 140 operated by a control panel 142. A white water collecting pan 116 is included in the shell 10 and the suction means 112,114,118 therein can be displaced about the axis of the shell 10. The forming wire 11 is lifted off and away from the vacuum box 118 before the farther end of the vacuum box 118 is reached so that a small amount of air is bled into the box 118 beneath the formed sheet to prevent water thrown off by the forming wire 11 and the shell 10 from deleteriously effecting sheet formation.

Title: Improvements in or relating to dictation apparatus
Filed: 1958-03-04
Abstract: 816,903. Magnetic recording and reproducing apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 4, 1958 [March 7, 1957], No. 6907/58. Class 40 (2). In a dictation apparatus in which the driving mechanism is controlled by parallel connected manual and foot switches, the latter is series connected with an additional switch which is open circuited during a recording operation. The embodiment is described with reference to a magnetic tape recorder in which tape is driven in a forward direction from a spool 2 to a spool 6 by the use of a jockey pulley 13 effecting a coupling between a driving wheel 8 and a driven wheel 11, and in a faster reverse direction by the use of a jockey pulley 14 effecting coupling between a driving wheel 9 and a driven wheel 12. In the particular application of the invention it is envisaged that a person dictating would require to control by hand the forward and reverse drive and to be able to both record and play back, while a typist would use a foot control to effect forward and reverse drive, but that such control would be rendered ineffective when the machine was set to "Record." Fig. 2 shows the switching arrangement whereby hand switches 20 or 23 close the circuit of a relay 15 or 16, respectively, to move jockey pulley 13 or 14 to effect forward or reverse drive, respectively. The typist's foot control, conveniently arranged as a rocker switch, has switch contacts 25 and 26 in parallel with switches 20 and 28, respectively, but these are rendered ineffective by a series switch 27 which is opened when the machine is set at " Record."
