IPC: H04M15/10
Filed: 1964-01-01
Abstract: 1,010,021. Automatic exchange systems. SIEMENS & HALSKE A.G. Jan. 1, 1964 [Jan. 2, 1963], No. 28/64. Heading H4K. In an arrangement for storing signals such as meter pulses in a store allocated to an appropriate line, the signals are fed to a counter MSP1 of scale n (=10), which counter has two outputs, one of which, el, is energized when the counter is full, and the other, e2, when the count is non-zero and less than n. The counters are scanned cyclicly by scanner AW. If e1 is energized, then when scanning takes place G1 opens to cause the subscriber's line circuit to energize an identifier JD which addresses an appropriate store which is also fed over gate M with a signal indicating that the count in this store must be advanced by n. The G1 output also zeroizes MSP1. When a release signal is received over E, with the count in MSP1 less than n, gate G2 is opened on scanning and the subscriber's identity fed to AE as before but in the absence of a signal over M only 1 is added to the count. The output of G2 reduces the MSP1 count by 1 each time. Release is controlled over terminal B which is not energized until MSP2 has been counted down to zero.

Granted: 1998-05-31
Abstract: An improved fold and wrap package providing containment of a catamenial pad prior to its use and for conveniently disposing of a soiled catamenial pad. The fold and wrap package comprises a wrapper comprising a single strip of material having a flap panel, a central panel, and an end panel; and preferably a tape tab for securing the wrapper in a disposal configuration to provide convenient disposal of a soiled catamenial pad wrapped in the wrapper. The fold and wrap package is initially configured to have a pouch and a flap. The pouch is formed by folding the end panel back upon the central panel and frangibly bonding the end panel to the central panel at the longitudinal edges so that the end panel may be easily peeled away from the central panel to provide convenient disposal of a soiled catamenial pad. The pouch is designed so that an unused catamenial pad may be disposed within the pouch with the flap being positioned over the mouth of the pouch and frangibly bonded to the pouch to securely close the pouch prior to use. The fold and wrap package is used by peeling the tape tab from the pouch, peeling the flap away from the pouch by breaking the frangible bonds between the flap and the pouch, removing the unused catamenial pad from the pouch, peeling the end panel from the central panel to open the pouch such that the fold and wrap package is a flat wrapper (these previous two steps may also be done in reverse order), securing a soiled catamenial pad to the wrapper, disposing the wrapper and the soiled catamenial pad into a disposal configuration, and securing the wrapper and the soiled catamenial pad in its disposal configuration by securing the tape tab to another portion of the wrapper. <IMAGE>

IPC: H02P1/00
Filed: 1929-01-01
Abstract: 306,529. Siemens - Schuckertwerke Akt.-Ges. Feb. 23, 1928, [Convention date]. Systems depending on static transformers.-In systems in which an alternating-current machine such as a rotary converter 1 or a synchronous motor with starting cage windings is supplied through a boosting transformer 3 , means mechanically controlled by the main switch 4, on the switch 4 being opened automatically or by hand, cause the transformer 3 to be brought into the starting position in which the machine will receive the minimum voltage favourable for starting. The transformer 3 may have one coil rotatable and is controlled by a reversible motor 6 energized from a separate supply 10. If the transformer 3 is not in its starting position when the switch 4 is opened, the motor 6 is energized through the trailing switch 7 connected to the transformer 3 and through the switch 41 connected to the switch 4. To regulate the starting potential, the transformer 3 can be adjusted in one direction or the other, prior to closure of the switch , by depressing one or the other of two control keys 11, 12. Limit switches 8, 9 automatically switch out the motor 6 when the transformer 3 has reached an end position. After the machine has started, the booster transformer is adjusted to raise the voltage. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a booster comprising a " tapping " transformer. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in valve arrangements for use in gas-blast electric switches
IPC: H01H33/56
Filed: 1932-01-02
Abstract: 389,938. High-potential switches. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A. -(Assignees of Allgemeine Elektricitats- Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Jan. 2, 1932, No. 141. Convention date, Jan. 2, 1931. [Class 38 (v).] Pneumatic actuation; arc - rupturing in switches.-In a valve arrangement for controlling the flow of compressed gas in a gasblast electric switch of the type in which a main valve for shutting off the compressed gaspipe is brought into operation by a control valve, a relief valve operated by the release member of the switch allowing air to escape from the control valve to bring the valve arrangement into operation, in order that the main valve shall close quickly after operation compressed gas is separately or simultaneously applied to chambers from which air is allowed to escape when the main valve is opened, this compressed gas being taken from a pipe located behind the main valve. As shown in the Figure, the main valve has a stepped piston f with a small port h connecting its opposite sides and the control valve has a similar piston k with a similar port (not shown). The relief valve o when operated by an electrical release member m exhausts the pressure from the space z behind the piston k of the control valve, the consequent movement of the piston k exhausting the pressure from the space a behind the main valve f so that a blast of gas is produced at the switch contacts. In order that the main valve shall close rapidly after operation, pipes p, v, w are provided so that the rise of pressure behind the main valve during the switch operation shall rapidly provide a sufficient pressure in the spaces in the valves from which air has been allowed to escape. The pipe v feeding the space z in the control valve is fitted with a non-return valve u and the pipe w feeding the space i at the back of the piston of the main valve is fitted with a throttle valve x adjustment of which can vary the rate at which pressure is restored in this space. The return movement of the main valve may be assisted by a spring.
