Patent EP-0378169-A2 (EP)
Inventor: BEACH DAVID EASTON C O EASTMAN
IPC: G03C3/00
Filed: 1990-01-09
Abstract: A film cassette (1) is disclosed wherein a film spool (5) having a filmstrip coiled about it is selectively rotatable in opposite directions to advance a leader portion (43) of the filmstrip through a film passage slit (26) to the outside of the cassette shell (3) and to return the leader portion to the inside of the cassette shell. A pile-like material (27), such as velvet or plush, consisting of short close flexible fibers (87) is secured to the cassette shell along the film passage slit to prevent ambient light substantially from entering the slit. The leader portion has at least one hole (89) adapted to receive a sufficient number of the fibers to allow the fibers to engage the leader portion to prevent its casual creep rearward in the film passage slit. The fibers have a resistance to displacement from the hole which can easily be overcome by rotating the film spool to move the leader portion.

Abstract: In a computer system with a function of discrimi­nating an FDD (13) used as an external storage device, a counter (21) for counting step pulses (SP) is used to set a flip-flop (22) in an ID response state, thereby maintaining an identification mode different from a nor­mal read/write mode. In this identification mode, ID data is preset in a shift register (20) by an output signal (TC) from the counter (21). The shift register (20) outputs ID data in synchronism with the step pulse (SP). The ID data from the shift register (20) is transferred to an FDC (14) trough an interface signal line of the FDD (13) by a NAND gate (26) gate-controlled in accordance with an output from the flip-flop (22). The CPU (10) identifies the specification of the FDD (13) connected to the system in accordance with the ID data transferred via the FDC (14).

Abstract: A process for producing large beads of a copolymer comprised of from about 60 to 99 weight percent of a mono-vinyl aromatic monomer such as styrene and from about 1 to 40 weight percent of an acrylic acid monomer such as methacrylic acid is disclosed. The copolymer beads obtained in high yield by this process are much larger in diameter than those obtained by prior art methods and are directly suitable for use in molding applications since pelletization is not required. The large beads are produced by adding a small amount of a water-soluble polymer such as polyvinyl alcohol to an aqueous polymerization mixture after about 10 to 75% conversion of the monomers has been achieved.

Abstract: A device for transmitting torque from a power unit (19) to a drill string (17) or other rotary pipe, and which is constructed upon reverse rotation to preferentially break a threaded connection between the device and a stand of the pipe without disconnecting a plurality of lengths of pipe (20) in the stand from one another. The torque transmitting device (11) includes a tubular structure (32) having a thread (38) adapted to be advanced into engagement with a thread (30) at an end (29) of the pipe, and a shoulder ring (44) carried by and rotatable with the tubular structure (32) and having a shoulder (57) engageable against a shoulder (31) of the pipe to limit advancement of the threads (38,30) together, with axial forces being transmitted from the tubular structure (32) to the ring (44) by interengageable bearing surfaces which permit limited rotary movement of the tubular structure (32) and its thread (38) relative to the shoulder ring (44). The bearing surfaces are constructed to retain the ring (44) in a predetermined fixed axial position relative to the tubular structure(32), preventing axial movement of the ring (44) relative to the tubular structure (32) as the structure (32) turns about its axis relative to the ring (44). A C-spring (45) disposed about the tubular structure (32) acts to yieldingly urge the ring (44) rotatively relative to the structure (32) in a joint breaking direction. Two elements connected to flanges formed on the tubular structure (32) and ring (44) respectively are received between opposite ends of the C-spring (45) and act to apply the force of the spring (45) to the ring (44) to urge it rotatively relative to the structure in the joint breaking direction. Pins (46) received radially between the tubular structure (32) and the ring (44) limit their relative rotation to an angle constituting a small portion of a turn.

Abstract: As is usual in coordinate-measuring technology, the described solution proceeds from a concept in which the guides for the two coordinate directions are built up on one another. However, the drive of the auxiliary carriage that is guided in the fixed part primarily with respect to the first coordinate direction acts not on said auxiliary carriage itself but on the carriage guided thereon and supporting the stand. The auxiliary carriage must thus absorb only the drive forces in the X-direction, that is to say the direction in which the stand is guided on it itself, while in the Y-direction, which is perpendicular thereto, it is simply pulled along via the guide for the stand, which is built onto said auxiliary carriage. Since the auxiliary carriage has only a relatively low mass and the principal mass of the machine is formed by the stand itself and the carriage supporting it, it is therefore possible to ensure for the direction of motion of the auxiliary carriage as well a drive that is essentially near or at the centre of gravity of the parts to be driven. <IMAGE>

Abstract: The invention provides a liquid crystal electro-optical device of the reflective type. The device comprises a twisted nematic liquid crystal layer (104) sandwiched between two opposed substrates (101, 103), a polarising element (106) for polarising light entering the liquid crystal layer, and a reflective element (102) for reflecting light transmitted by the liquid crystal layer. The polarising element, the liquid crystal layer and the reflective element are arranged to co-operate in one state of the electro-optical device so as to convert the light between linearly polarised light at one surface of the liquid crystal layer and circularly polarised light at the other surface of the liquid crystal layer. Further, the direction of polarisation of light emerging from the liquid crystal layer is altered relative to the direction of polarisation of light entering the liquid crystal layer.

Abstract: For the adjustment of a throttle valve (4) arranged in the intake connection of an internal combustion engine, a device is proposed in which the throttle valve (4) can be adjusted both by the accelerator pedal (2) and by a control motor (7) by way of control elements (1, 5) and a coupling element (9) independently of one another. Stops (14, 15, 16) fixed to the housing ensure that the movement of the control elements (1, 5) and of the coupling element (9) is limited in the opening and closing direction of the throttle valve (4), the throttle valve positions LLmin, LLnot and VL simultaneously being defined. In the device it is ensured that the throttle valve (4) is automatically swivelled into an emergency running position (LLnot) should the control motor (7) or the associated electronic control device (8) fail. This aim is achieved without a special emergency running spring which has a favourable effect on the required size of the control motor (7). <IMAGE>

Abstract: 2.1 For scavenging an industrial furnace, protective gas is introduced into the furnace while the furnace atmosphere flows away via a throttling point, flow metering being carried out. The intention is to optimise the duration of the protective gas supply. 2.1 According to the invention, the flow metering is monitored and the protective gas supply switched off when the flow metering settles at a constant value. By deriving electric signals from the flow metering and computational differentiation of these signals over time, the protective gas supply can be ended automatically in dependence on the process when the differential quotient has fallen below a predetermined value. <IMAGE>
