Title: Improvements in and relating to the control of alternating current motors
IPC: B66B1/12
Filed: 1937-04-02
Abstract: 493,354. Control of A.C., motors; controllers. BRITISH THOMSON-HOUSTON CO., Ltd., PETCH, JUN., T. H., and LIDDIARD, H. W. C. April 2, 1937, No. 9434. [Class 38 (iii)] Dynamo-electric braking.- Upon return of an induction motor controller towards its off position contacts are opened, and, if no deceleration is produced the opening of these contacts is effective to reverse the connections of the motor to the supply. A control lever 11, Fig. la, coupled to a master controller 204, Fig. 2, is pivoted on an axis 12, on which is mounted a segment 13 carrying contacts A, B, C, D, the segment 13 being coupled to a drum 14 engaged by brake shoes 15 biassed by a spring 18. The control lever 11 carries bridging contacts co-operating with the contacts A, B, C, D. With the controller 204 in its off position the coil 28a of a contactor is energized to close contacts 28b, 28c, 28e, 28g and 28,j, and open contacts 28d, 28f, 28h. When the controller is moved in the forward direction the switches A, B, are closed or remain closed so that the coil 28a is maintained energized through a segment 205. A coil 21a is energized over interlock contacts 22c, 23c, of contactors 22b and 23b, and the forward contactor 21b closes to start the motor 201 in the forward direction. Further movement of the controller energizes in sequence coils 23a, 24a, 25a, 26a, 27a, whereby accelerating contactors close to cut out steps of resistance 203. When deceleration is required the lever 11 is moved towards the off position first opening switches A and B. The coil 28a is maintained energized over contacts 217 of a reverse power relay, contacts 216 of an over-speed device and contacts 215 of a device which operates to open these contacts when the speed of the motor does not correspond with the position of the control lever. Thus with positive loading of the motor, the motor remains connected to the supply, and is decelerated by the insertion of steps of starting resistance 203 but if the loading is negative, the contacts 215, 216, 217 effect de-energization of the coil 28a. Thus the contactor 21b is opened and the reverse contactor 22b closed, the contactors controlling the resistance 203 also opening. The motor is thus connected reversely to the supply. When the switches C and D close the coil 23b is energized to give a second braking control step. Further movement of the controller towards the off position gives braking control until the off position is reached, and the control circuits restored to their original condition in readiness for the next operation. If, after opening of the switches A and B by movement of the controller toward its off position, the controller is then moved away from the off position with positive loading acceleration takes place by removal of starting resistance, while with negative loading acceleration commences when the switch A recloses. The device 215 may take the form of a governor co-operating with a cam operated by the lever 11.

Title: A method of feeding the coagulating liquid whilst spinning artificial silk
IPC: D01D5/06
Filed: 1932-04-02
Abstract: <PICT:0391592/IV/1> <PICT:0391592/IV/2> Each of a number of artificial silk spinning nozzles arranged in a common coagulating vat is supplied with fresh upwardly flowing coagulating liquid which has been brought to the same temperature as that of the liquid already present in the vat.  The liquid passes from the vicinity of each nozzle to an overflow device and is collected, regenerated, and again brought into circulation.  As shown in the drawings, a vat a has a channel c on one side for running off waste, and an overflow channel d on the other side, separated from the vat by a sill e on which rest thread-guides g. Coagulating liquid flows from a feed pipe i through a pipe h and return pipe k to swan-neck outlets l from which it is delivered to pipes n and perforated delivery pipes o.  The perforations in the pipes o increase in size from the point of connection with the pipes n outwards for ensuring an equal rate of flow of liquid to take place from each perforation.  Each pipe o serves a number of spinning nozzles p, and the perforations preferably point downwards away from the sill e.  The long path of the liquid in the pipes h, k, l, n ensures its delivery at the same temperature as that of the liquid already in the vat.  Fresh liquid rises from the perforations of the pipes o and flows past each nozzle and then towards the sill e and overflow channel d.

Title: Improvements relating to information transmission systems

IPC: H04Q9/04
Filed: 1963-03-12
Abstract: 1,012,469. Electric selective signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Feb. 14, 1964 [March 12, 1963], No. 9719/63. Heading G4H. In a data transmission system comprising a central station, Fig. 1, and a plurality of field stations, Fig. 2, normally called cyclically in sequence, while the central station is transmitting control data to one field station, the immediately preceding field station in the sequence is transmitting indication data to the central station. This is achieved by constructing the central station, Fig. 1, apart from some common control circuitry, of two identical halves. While one half is transmitting the other is receiving and then the one half receives and the other transmits. The transmitted data comprises a sequence of binary bits, a " 0 " being represented by a frequency f 2  and a " 1 " by a frequency f 3 , and the bits are interleaved with bursts of an intermediate frequency f 1  which synchronizes a receiving station with a transmitting station. As described, a control unit 4, Fig. 1, at the central station sets the address of a field station to be transmitted to in a three stage register AG. A counter 5 is then stepped by a clock-pulse generator 3 to transmit this address and to follow it by data read from one of three registers TG1, TG2 or TG3 as selected by the control unit 4. At each receiving field station the address and the following data are registered in a temporary register TR2, Fig. 2, under the control of a counter 8 stepped by the clock pulses which interleave the data pulses. When all the data is registered, at that field which corresponds to the transmitted address an address recognizer 12 responds and, providing a check performed by a unit 11 is satisfactory, opens one of two gates IG4 or IG5 to transfer the data from the temporary register to one of registers RG4 or RG5 respectively. While this transmission is going on, that field station which was last transmitted to will be transmitting, in a similar manner, and producing its own clock-pulses, to the other half of the central station. Such a field station will not have to transmit its identity, however, since the central station will know that it is the field station previously transmitted to. This process repeats and although the control unit 4 would normally call the field stations cyclically, this sequence can be changed. Specification 1,012,468 is referred to.

Title: Transmission network
Inventor: BROWN PAUL ANTHONY
IPC: H04B3/54
Filed: 1997-06-26
Abstract: A power transmission network (40) is disclosed which includes input means (52) for the input of telecommunication signals having carrier frequencies greater than 1MHz onto the network (40), and a means for removing similar speech and/or data signals from the network. Preferably a network conditioning element (52) is used which includes a low pass filter portion for filtering out a low frequency high amplitude mains power signal, and a coupling element for input and/or removal of telecommunication signals from the network. In this way both speech and data signals can be transmitted at carrier frequencies of greater than 1MHz along a standard electricity distribution and/or transmission network which when conditioned provides a larger available spectrum per unit length of network and greater transmission capacity than previously known. The quiescent noise level of the conditioned network is also much reduced thus permitting lower signal injection levels for a given signal-to-noise ratio and a consequential reduction in spurious radiation from the network. <IMAGE>

IPC: C02F11/00
Filed: 1989-02-24
Abstract: An advertising device is composed of several adjacent image elements (1) that are able to rotate around their longitudinal axes. Each individual image element carries on each side an image carrier (2) which receives a longitudinal strip of the whole advertising image. The cross-section of the image carrier has essentially the form of a box (21) provided with an opening (5) on the side facing the image element (1). A leaf spring (3) is fastened with rivets (4) to the image element (1). The image carrier bears with its opening (5) against the free end (31) of the leaf spring (3), so that latter can ingress into the box (21). The image carrier (2) then slides downwards until it reaches a stop and the leaf spring (3) holds it immovably on the inner side of the box (21). The assembly is dismounted in the reverse order. It thus becomes possible to easily exchange image carriers (2) and to replace them on the spot by new, already prepared image carriers.

Title: Method for transmitting gaseous trace element particles from flowing hot gas into powdered matter
Inventor: HAEMAELAE SIRPA KARIMAANKATU
IPC: B01D53/50
Filed: 1988-05-06
Abstract: The present invention relates to a process for causing gaseous trace element particles to pass from a flowing hot gas into a dust by means of water. According to the inven­tion, a mixture of the hot gas and water drops is caused to flow substantially up­wards at such a velocity that the water drops remain in the gas flow and for a period long enough for most of the mass of the water drops to evaporate in order to cool the gas and to increase its relative humidity. After the gases have reached their wet temperature they are brought into a turbulent state in order to cause the dust particles and the water drops which have decreased through evaporation to im­pinge against each other in order to pro­duce in the aqueous film which covers the dust particles an exothermal ion reaction between the gaseous water-soluble trace element particles and the dust particles. Thereafter the mixture is caused to flow further in order to evaporate the remaining water by means of the heat of reaction so that a dry end product is obtained.
