Abstract: ABSTRACT     A pre-wire  routing  apparatus and  method   is provided during construction of a building to provide an inexpensive way to later install a  wiring  interconnect between  first  and  second terminal  locations.    The apparatus  includes  a  strand  of  flexible   material. preferably string  which has an enlarged tail element at a trailing end and an enlarged head element  connectable at  a  leading  end.  Fastening  structures  such  as  a cable  tie,  is  secured to the  leading  end  to  allow selected  connection of the head element to  the  strand after the strand has been threaded along an interconnect pathway   through  an  interior  wall  portion  of the building.   The fastening structure preferably  forms  a leader to facilitate installations the tail element is a pull  ring  and  the  head element  is  a  waisted  rod.          Protector  sleeves may be positioned in opening 5, e.g.. bores, formed in the internal framing elements  and,  in an  alternative  embodiment,  a  sheath  surrounds   the strand.   The method has the steps of  forming  openings through  the  internal  framing elements  to  define  an interconnect   pathway  between  a  pair   of   terminal locations  through  adjacent openings and  the  interior spaces  between  the  framing  elements   installing   a flexible strand along the pathway and securing  opposite ends of the strand at a respective terminal location.

Abstract: DISTILLATION APPARATUS AND METHOD                 ABSTRACT OF THE DISCLOSURE An apparatus and method for fluid distilla-tion in general, and in particular, of water, adapted for consumer or home use, but capable of being made and operated so that it is suitable for separating solvents and solutes and other industrial use.  The apparatus includes a housing having divider structure to form one or more compartments for receiving water to be dis-tilled.  The divider structure also presents a fluid passage for receiving water vapor which is formed when the upper portion of the water in the housing is boiled by a heater.  An aerator is provided in the housing below the heater and in a location within the water compartment.  The aerator operates to direct air under a slight pressure into the water so that air bubbles can be generated in the water.  The air bubbles will rise and break the surface of the water as the upper part of the water is being boiled by the heater.  This causes a vapor pressure to be generated in the space above the water level and water vapor is then caused to move through the fluid passage downwardly to a lower chamber in which the water vapor is collected as a condensate.  As the water vapor moves downwardly in the fluid passage, it moves in heat exchange relationship to the water in the compartment of the housing. Several embodiments of the housing of the present invention are disclosed herein.

Abstract: Disclosed is a portable continuous infusion apparatus for administering an injectable liquid to a patient. The apparatus expells the contents of a syringe on a time controlled basis. It employs two separate springs, with one spring used to power a clockwork and another spring to power a gear rack to advance the syringe plunger or piston. Opening and shutting the apparatus cover automatically winds both springs simultaneously. A safety prevents closing the cover unless the springs are wound. Advancement of the gear rack is adjustable by a control which acts on an escapement lever which regulates an escape wheel. The control moves the escapement lever axially so it can engage a different number of wings on the escape wheel, thereby regulating the incremental advance of the gear rack acting on the syringe plunger.

Abstract: A method for feeding the growing substrate, such as peat, soil, compost, crushed mineral wool, perlite, vermiculite, or bark, by means of a feeding equipment into the cells (6) of the set (4) of growing cells placed underneath the said equipment. The feeding equipment consists of two horizontal feeding rolls (2), which are placed side by side and which are parallel to each other, pins (3) of a resilient material, e.g. rubber or plastic, preferably polyurethane, being arranged as projecting from the roll faces (7), the said pins (3) projecting radially. The pins (3) are placed in the normal planes of the axes of the feeding rolls (2) alternatingly in each feeding roll (2) so that, in the space between the feeding rolls (2), the pins (3) on the feeding rolls (2) are placed as interlocking each other. The feeding rolls (2) are rotated in opposite directions so that the roll faces (7) of the rolls (2) directed towards each other have a downwardly oriented direction of rotation. The filling material of the cells (6), i.e. the growing substrate, is fed preferably as moist at a high speed into the cells (6) by rotating the feeding rolls (2) at a rotation speed of 500 to 1000 r.p.m. - the lower the specific weight of the filling material, the higher the speed of rotation. Thereby the filling material is, by the effect of the circumferential velocity of the feeding rolls (2) of about 3 to 10 m/s, rushed in the vertical direction into the cells of the growing cell system (4) so that any filling material introduced into the cells (6) earlier is compacted by means of the kinetic energy of the filling material, beginning from the bottom.

Abstract: The invention proposes an electrical contact terminal arrangement for cycle fenders constructed from a molded multi-layer laminate of plastic with at least one metal foil layer embedded therein. The arrangement includes a metal head having a substantially flat underside which is pressed against an outer surface of the fender. A shaft-like projection is formed onto the underside of the head, extending at right angles to the underside and when mounted penetrating the fender. An attachment means anchored on this projection secures the contact terminal arrangement in the cycle fender. In order to attain long service life of the contact location between the metal foil and the contact arrangement projection, and to attain low transitional resistance, only one shaft-like projection is provided, disposed concentrically with the head. A large number of contact protrusions is embodied on the outer circumference of the shaft-like projection, extending in the longitudinal direction thereof. The attachment arrangement likewise concentrically surrounds the shaft-like projection.

Abstract: The invention relates to a receiving arrangement 4-1 for SHF signals, comprising a rectangular waveguide filter 5 formed from resonators 10-1 to 10-4 arranged in cascade, a SHF signal arrangement 6 containing a microstrip circuit and a microstrip to waveguide filter transition connection to this circuit.Generally, such a receiving arrangement is not suitable for use in radiators comprising a partly shown polarization converter 3 with two such receiving arrangement 4-1 each receiving one of two mutually orthogonally polarized signals. When the prior art receiving arrangements are used in these radiators, the channel separation is inadequate.According to the invention, an adequate channel separation is obtained by providing the microstrip to waveguide filter transition in the waveguide filter and matching the filter 5 thereto. As a result thereof, the receiving arrangement 4-1 becomes more compact and has a very low reflection and, in addition, it is no longer necessary to adjust the transition to the waveguide filter 5.Preferably, dimensioning is realized by the choice of the size in the axial direction of the end resonator 10-4 and/or the choice of the dimensions of the coupling aperture which connects the end resonator 10-4 to the adjacent resonator 10-3.
