Abstract: ABSTRACT         A slide switch having snap action and teaseproof features that are provided by molded plastic spring detent means attached to the contact carrier of the switch.  The spring detent means includes a thin, resilient plastic band around the contact carrier and having long side legs with respective outwardly extending detents thereon.          These detents operatively engage detents in the switch housing.  A thin, resilient plastic strap or spring extends between the ends of said plastic band and has an upwardly protruding V-shape cam follower.  The cam follower slidingly engages a V-shaped notch or cam on the bottom surface of the switch actuator.  Normally the cam follower is centered in the V-shaped notch.  There is relative movement between the actuator and contact carrier for a short distance while the detent and spring of the spring detent means store energy.  At some predetermined position the stored energy is suffi-cient to snap the contact carrier past the detent on the housing.  The detents and the V-shaped cam and cam follower provide the teaseproof feature.

Abstract: A B S T R A C T            The  invention  provides  a holding device for one or more rows  of  bottles  or  the  like.    The  device comprises essentially  a  sleeve  of sheet material having upper and lower walls  and  side  walls,  and the device is applied to  the  containers  by  passing it over the containers so that  the  tops  pass  through  aperturs  in the base wall and  then  apertures  in the top wall.  The containers are locked  to  the  device  by  virtue  of  the device having locking  tabs  or  a  locking wall which folds upwardly by virtue  of engagement with the containers, but locks under the  container rims or beads on the caps of the containers or  at  the  container  mouths,  preventing removal of the container   by   movement   in   an   opposite  direction. Preferably,  there  are  two  locking devices which engage the  container  rims  or  beads at opposite sides, and lie in an inclined position relative to the container axis.            The  sleeve  is  preferably of rectangular or square cross section  so  that  it  can  be displaced to flattened form about  crease  lines  lying at a pair of opposite corners, for transportation.

Abstract: ABSTRACT         Disclosed is a power generating system which derives power from the action of water waves.   The system comprises a main support body mounted above a water surface subject to wave action on leg members secured to the bottom beneath the water surface.  The support body has a central output shaft coupled to drive at least one output device.  A plurality of drive shafts are coupled to apply torque to the output shaft in one direction only, the drive shafts being driven by hydraulic turbines, each of which are supplied with fluid under pressure by reciprocating pumps having pistons connected to and driven by floats which are  movable up and down in response to waves moving beneath the support body. Ramps are provided beneath the water surface and surrounding the floats to increase the height of waves moving past the floats. The system produces a substantially  constant turning action and can be made sufficiently large  to derive energy from more than one wave at a time.  With a  large scale system, high power output is possible and by arranging the floats in a circular pattern, wave direction  is unimportant.   The output device may be an electrical generator or compressor, for example.

Abstract: ABSTRACT        A class of polyamides comprising recurring units having substituted-quaterphenylene radicals is disclosed.   The polymers comprise recurring units of the formula   wherein each of A and B is a divalent radical, except that B can represent a single bond; R and R1 are each hydrogen, alkyl, aryl, alkaryl or aralkyl; and c is zero or one; and wherein, when c is one, at least one of A and B is a substituted-quaterphenylene radical having the formula   where each U is a substituent other than hydrogen, each W is hydrogen or a substituent other than hydrogen, each p is an integer from 1 to 3, each X is hydrogen or a substituent other than hydrogen and each r is an integer from 1 to 4, the U, Wp and Xr substitution being sufficient to provide the radical with a non-coplanar molecular configuration; and wherein, when c is zero, A is a substituted-quaterphenylene radical as aforedescribed.         The polyamide materials exhibit solubility in select solvents including those of the non-amide type and are character-ized by high electron density substantially cylindrically distributed about the long axis thereof.  The molecularly oriented polymers are optically uniaxial and are suited to application in optical filter and other devices where a highly refractive and birefringent polymeric material is desired.

Abstract: ABSTRACT     A device for connecting two pipes for carrying abrasive material under high pressure employs  a flange member welded to an end of one of the pipes and a ring member welded to an end of the other pipe.  The pipes and both members have the same internal diameter.  One or both pipes may be cold formed into a curved shape.  An outward-extending rib on the ring member and a should-er on the flange member are encircled by a tension sleeve having an inwardly directed lip at each end.  The tension sleeve comprises two semi-circular halves. One or more continuous circumferential bands encircle the tension sleeve to hold the two halves together against radial separation.  An anti-friction bear-ing assembly between one of said lips and a shoulder on the ring member permits relative turning movement between said pipes.  An axial projection on the ring member is received within a recess in the flange member, and seal means are provided between the projection and the recess.

Abstract: Abstract of the Disclosure A glass optical waveguide preform is  formed by depositing coatings of glass soot on a mandrel.  The mandrel  is  removed  and  the  porous  preform  is consolidated.   One  end  of  the preform  aperture  is closed,  the aperture is evacuated, and the remaining end of the preform is heated, whereby it is caused to close.   An  intermediate  fiber  is  drawn  from  the resultant  consolidated  preform,  the  entire  aperture closing during drawing due to the low pressure within the aperture.  The intermediate fiber is severed into sections, each of which functions as a mandrel for the deposition of a further coating of cladding soot.  The resultant composite article is consolidated and drawn into an optical fiber.     When   soot   preforms   formed   by   conventional deposition techniques are consolidated, the surface of the  aperture  formed  by  removing  the  mandrel  often devitrifies, thereby   necessitating   an   etching treatment to remove the devitrified layer.  To prevent the   formation   of   a  devitrified   layer   at   the aperture-forming surface during the consolidation step, the rate of soot deposition is initially reduced so that a stratum of fine soot is initially deposited on the mandrel.  The stratum is initially discontinous, but  after  a plurality passes  of  the  soot-producing burner,   it  becomes  continuous.  Thereafter,   the formation  of  the  remainder  of  the  soot  preform continues in a conventional manner.

Abstract: ABSTRACT     Enterally administrable diagnostic compositions for investigating alimentary functions comprise multiple units of a size of at the most 5mm, preferably between 0.5 and 1.3mm, in particular between 0.7 and 1.0 mm, each unit comprising a tracer-binding agent such as an ion exchange resin to which a radioactive tracer substance with a half-life of at the most 5 days, in particular 99mTc, 113mIn  111In and 129Cs, is associated, the tracer-binding agent being formulated with pharmaceutically acceptable excipients, in particular granulating excipients in such a way that the exposure of the gastrointestinal mucosa to the tracer-binding agent is reduced and that the units do not disintegrate during the passage through the gastrointestinal tract.  Preferred units comprise cross-sectionally substantially homogeneous multi-component cores in which the tracer-binding agent is granulated with one or more excipients and which are optionally coated with a diffusion coating permitting the labelling of the units to be performed at the site of use by immersing the units in a solution of tracer substance.  Tracer-binding agents are normally present in an amount of about 2-20% by weight, preferably about 5-10% by weight, calculated on the units.  Due to low leaching and the non-disintegrating properties, the composition can be used to investigate gastric emptying also of the last 20% of a food bolus, cf. Fig. 2 which illustrates the average gastric emptying pattern for 7 healthy volunteers (A) compared to the emptying from a person with the "Giesskannen" phenomenon (B).
