Title: Applying adhesive paste to connector strip for filter cigarettes
IPC: D21H23/58
Filed: 1980-07-11
Abstract: Adhesive paste is applied to a travelling connector strip (13), which is then divided into sections (47) each of which is wound around a filter/cigarette (51) [Fig. 4] for connecting the same. The application involves the deposition in the region of a side edge, at which the connector strip sections are adhesively joined to the cigarette (Z), of a strip of paste (48e, f) which extends in the feed direction of the connector strip and which is thicker than the layer of paste in other regions. The thicker strip of paste (48e, f) is deposited at a spacing from the side edge of the connector strip and is interrupted in regions (44a, b) in which the connector strip is divided into sections. In these regions a thinner layer of paste is deposited. Zones (46a, b) are paste-free. The paste is applied using a roller (39) [Fig. 2] of which the surface is recessed to different depths. The recesses extend in the direction of rotation and a deeper recess (41e, f) is provided in the appropriate position on said roller in order to deposit the thicker strip of gum. <IMAGE>

Title: A Gas-blast Circuit Interrupter
IPC: H01H1/38
Filed: 1981-12-08
Abstract: A gas-blast circuit-interrupter has a fixed electrode 84 and a main fixed contact 96 coaxial with an axis 100, a main movable contact 108 is movable along the axis 100 in sliding engagement with electrode 84 and a arcing contact 110 is coaxial with the axis 100. An operating member 112 connected to contact 108 is guided for movement along the axis 100. Abutments 126, 140 on the member 112 and to contact 110, respectively are forced together by a spring 118. On closure, member 112 moves towards the fixed contact 96; contact 110 abuts contact 96, abutments 126, 140 separate and contact 108 disengages contact 110 and engages contact 96. On opening, member 112 moves away from contact 96 and causes contact 108 to disengage contact 96 and to engage contact 110. During this period, abutments 126, 140 approach one another while contact 110 is maintained stationary by spring 118. Abutments 126, 140 then engage so that further movement of member 112 disengages contact 110 from contact 96. The gas blast is achieved by arc heating effects and by piston 142 moving in cylinder 146, gases exhausting from chamber 82 through contacts 110, 96. <IMAGE>

Title: Gasification and production of acetylene from coal
Inventor: KIM CHI S
IPC: C07C1/00
Filed: 1982-04-26
Abstract: Particles of coal are injected into a high temperature region established by combustion of preheated hydrogen and oxygen, the hydrogen being supplied to the combustion zone in stoichiometric excess with respect to oxygen to provide a source of hydrogen to react directly with the carbon content of the coal to produce acetylene.

Title: An electrical terminal
Inventor: SMITH RAYMOND IVOR
IPC: H01R12/58
Filed: 1982-08-18
Abstract: A terminal for the plated through apertures of a circuit board comprises a pin 31 and a captive frusto-conical sleeve 32 disposed on the pin 31. In use, the terminal is pushed into the desired plated through aperture from the non-circuitry or terminal side of the board until a tapered portion 39 of the pin wedges the sleeve 32 between the pin 31 and the wall of the aperture to make a good electrical contact between the pin and the board without damaging the aperture. Connections may then be made by the wire wrap technique to a protruding longer part of the stem of the pin 31. When terminal removal or replacement is required, the pin is simply pulled back out in the reverse direction. If desired, the tapered portion of the pin may be disposed in the longer stem part 36 of the "t" but in that case the pin would be pushed through from the circuitry side of the board and the sleeve would be disposed on the longer stem part. <IMAGE>

Title: Telescopic pipe joints
Inventor: CAMPBELL JOSEPH K
IPC: F16L27/02
Filed: 1983-02-01
Abstract: There is provided a pipe joint between a first pipe end 12 and a second pipe end 14. The pipe joint includes telescoping means allowing the ends to move axially with respect to each other while maintaining fluid-type communication. The joint also includes a plurality of contraction units 23 located externally of the pipe ends and the telescoping means. Each contraction unit includes a rod member 24 with one end engaged with a first flange member 16 fixed with respect to the first pipe end 12, while the other end of the rod member is secured to a piston 36 riding in a cylinder 40 with a cylinder bottom 42, the cylinder being engaged with a second flange member 18 fixed with respect to the second pipe end 14. The cylinder bottom 42 lies in between the piston and the previously defined one end of the rod member. A fluid conduit 71, 76, 79 connects the interior of one of the pipe ends with the cylinder volume lying between the piston and the cylinder bottom, so that the pressure inside the cylinder volume is a function of the pressure inside one of the pipe ends. This allows compensation for the expansion forces arising from pressure in the pipe joint, but does so with a structure in which the contraction units are not located directly opposite the telescoping means, thus facilitating disassembly for repair and other purposes. <IMAGE>

Title: Voltage-to-current converter and impedance synthesis circuit incorporating the converter
Inventor: BIENSTMAN LUC ARMAND
IPC: H03F3/26
Filed: 1984-10-19
Abstract: A voltage to current converter for converting a differential input voltage into an output current in a reference impedance has two inputs between which the input voltage is applied. First and second transistors (PM1, PM2) have output circuits which are connected between corresponding first and second converter outputs and corresponding first and second constant current sources (T2, T1) provide a first and second constant current respectively. The junction points of the output circuits and the constant current sources are interconnected through the reference impedance (R9) and the converter provides, at the first and second outputs, respective first and second balanced currents equal to the sum of the first constant current and the output current and to the difference between the second constant current and the output current respectively. The control electrodes of the first (PM1) and second (PM2) transistors are connected to the outputs of respective first (OA3) and second (OA4) operational amplifiers, the non inverting inputs (VFB, SMI) of which constitute the converter inputs whilst the inverting inputs are connected to respective ends (J1, J2) of the reference impedance (R9). <IMAGE>
