Title: Electrical earth-leakage circuit-breakers
IPC: H02H3/10
Filed: 1968-05-06
Abstract: 1,208,208. Protective arrangements. UNINORM ANSTALT. 6 May, 1968 [19 Dec., 1967], No. 21308/68. Heading H2K. A protective arrangement comprises a circuitbreaker with an earth leakage tripping coil 2 energized by a differential transformer 4 and a further tripping coil 3 connected to the secondary winding of a current transformer 5 in parallel with a positive temperature coefficient resistor 6 which may be disposed in the windings of the transformer 4. Under sustained overload conditions the voltage at the secondary winding of the transformer 5 is insufficient to cause the coil 3 to trip the circuit-breaker until the resistor 6 has been heated by the current flowing through it so that its resistance increases and causes more current to flow through the trip coil 3. With the resistor 6 disposed as shown, it will also be heated by the heat generated by the primary windings of the transformer 4. In the event of short circuit conditions, the coil 3 is sufficiently energized to trip the circuitbreaker without delay.

Title: Improvements in electric signalling systems, especially applicable to combined telegraph and telephone systems
IPC: H04Q1/442
Filed: 1919-09-01
Abstract: 149,139. Western Electric Co., (Western Electric Co.). Sept. 1, 1919. Simultaneous telegraphy and telephony.-When a telephone trunk is also used for telegrsphy, the usual 16-cycle ringing-current cannot be employed, because it is too nearlv of the same period as the Morse impulses. The invention comprises means by which the 16-cycle current supplied to the trunk at its outgoing switchboard end is replaced at an intermediate point by, say, a 133-cycle current, which is again replaced, before arriving at the incoming switchboard end, by 16-cycle current. The higherfrequency current is of such small amplitude as not to be distorted by the amplifying- valves which may be used in long trunks. In the arrangement shown in Figs. 1 and 2, the trunk L1, L2 is divided by a filter, consisting of condensers 30, 31, 32, 33 and an inductive bridge 3, which prevents through transmission of currents of higher frequency than 200. Ringing-current of frequency 16 from the line L1 passes through the circuit 4, 5 to a filter 8, which only passes current of about this frequency, and thence through a resonant circuit 10, 11 to a valve A1. which it overloads so that harmonics are developed in the out-put circuit. One of these harmonics is in the neighbourhood of frequency 133, and current of this frequency is transmitted by a filter 12, which is opaque to other frequencies, to an amplifying-valve A2. The amplified currents are transmitted partly to a rectifying-valve A3, which energizes a direct-current relay 19, and partly through contacts of the relay 19 to the line L2. On the other hand, current of frequency 133 from the line L2 passes through the circuit 6, 7 and filter 20 to amplifying-valves A4, A5 and a rectifying-valve A6, which energizes a relay 27 to connect the line L1 to a set of valves A7, A8, A9 acting as a generator of 16-cycle current. The valve A7 is coupled and tuned to oscillate at this frequency, giving currents which are amplified by the valves A8, A9 and purified by a filter 30. The adjustable resistance shunts 9, 21 are provided to prevent interference by Morse and switch-hook impulses. Modifications are described in which the 16-cycle current directly energizes a tuned relay to connect the higher-frequency current to the line L2.

Class 87(i) [Also in Groups XXIII and XXX] Apparatus for treating disc-like pottery in the biscuit stage consists of a fixed guide and an endless belt, the articles being rolled along between a portion of the belt and the guide by movement of the belt which co-operates with the guide in gripping the articles at two opposite parts of their rims, and a treatment zone contain, ing a multiplicity of treatment members acting on both disc surfaces of the articles during rolling, the length of the zone and arrangement of treatment members being such that each article is treated throughout at least one complete 'revolution of the article. The endless belt C is passed over pulleys B2, B3, one of which is driven, and over tensioning rollers D mounted on a spring-loaded arm D1. The belt is pressed towards the fixed guide F by rollers E, mounted in pairs on the opposite ends of arms E1 centrally pivoted to the ends of further arms E3 loaded by springs E7 through cranks E4. Plates or dishes H are inserted into the space between the belt and the guide by means of an outwardly curved portion F1 of the guide F. When no plate is present the approach of the belt to the guide F is limited by the spindles of the rollers E engaging a bar secured to the frame of the apparatus. The plates are brushed during conveyance by brushes J. K arranged in pairs of one above and one below the conveying plane of the plates, Fig. 4, adjacent pairs being driven so as to sweep in opposite directions. The bearings of each of the upper brushes J are vertically slidable by means of a handwheel M. In order that the brushes may be easily detached, each has at one end a separate hollow spindle L which rotates in the bearing L1 'and has a squared end for coupling to the end of the brush body N5. The spindle L is locked to or unlocked from the brush body by means of a long bolt N extending through the hollow spindle into threaded nut N1 in the brush body. Bolt N is turned by a tommy-bar N2 which is normally thrust into one of a number of pairs of locking grooves O in the end of hollow spindle L by means of a spring N3, and being manually withdrawn in order to turn the bolt.

Title: Improvements in or relating to address-printing machines
IPC: B41L47/24
Filed: 1934-07-26
Abstract: 422,769. Addressing-machines. ADREMA MASCHINENBAUGES., 20, Gotzkowskystrasse, Berlin. July 26, 1934, No. 21922. Convention date, July 29, 1933. [Class 100 (ii)] A list-sheet of any desired length is fed intermittently through an addressing-machine by a carriage which is movable step-by-step in the longitudinal direction of the list, a stationary clamping-device being provided for holding the list against movement while the carriage is being released from the list and returned to its initial position ready for the next feeding operation. The list may comprise a number of forms separated by perforations, the machine being stopped automatically when all the addresses have been printed on a form, whereupon the carriage is advanced by hand to provide a heading space on the next form. A carriage A comprising a frame 17 mounted on guide rails 6, 7 is advanced intermittently by means of a rack 9, which is reciprocated by a gear segment 11 oscillated on adjustable amount by connection with a rocking impression arm 3 and has ratchet teeth with which a pawl 40 mounted on the carriage is engaged. A list-sheet 21 passed through a gap in the frame 17 is clamped against a base plate 20 by spring-pressed arms 24, and the forward part of the sheet passes through a device B, which is secured in adjusted position on the rails 6, 7 and carries arms 64 adapted to clamp the sheet against a support 66. A cone 46 fixed in adjusted position on a rod 45 extending forwardly from the frame 17 engages a pivoted lever 57 when a predetermined number of addresses has been printed, thereby pulling on a Bo wden cable 56 and stopping the machine. The carriage A is then pushed forward by hand by means of a rod 35 until the end 351 of the rod engages a stop 75 on the device B, and is then returned to its starting position. During the return stroke, the rod 35 moves about parallel links 34, 37, the former being rigid with an arm 32 adapted to raise an arm 70 so as to release a spring-controlled lever 67, which then moves the arms 64 down on to the list. Meanwhile, an arm 31 also rigid with the link 34 releases the pawl 40, and a shaft 28 turning with the link 34 raises the arms 24 off the list. The arms 24 and the pawl 40 return to normal position as soon as the rod 35 is released, and the arms 64 are raised on the next printing stroke by a rod 78 connected to the arm 3 and adapted to return the lever 67 to normal position. When the list is to be printed without headings, the cone 46 is moved to the extreme left so that the machine is not stopped until the stop 75 is encountered; to prevent possible damage in the event of a failure of the stopping- mechanism, a rod 76 is provided for tripping the pawl 40.
