Granted: 1991-09-17
Abstract: SELF-DRAINING BASE PAN FOR AN AIR CONDITIONER     ABSTRACT OF THE DISCLOSURE          The base pan of a heat pump has a plurality of drainage openings formed near the periphery thereof such that either a single row coil or a multiple row coil heat exchanger may be used therewith to obtain adequate drainage of defrost liquid while at the same time preventing any downward movement of molten metal or hot particles through the drainage openings. The openings are located directly under the single or outside coil and a slanted shelf is placed directly under the loca-tion where the inner coil(s) would be placed, with the slanted shelf acting as a barrier for hot materials in a single coil apparatus and as a conduit for drainage to the opening when used with a multiple coil apparatus.

Title: Plastic film bag with integral plastic film tie element and associated fabrication methods
Inventor: RUTLEDGE GARY L
IPC: B31B1/90
Filed: 1988-11-03
Granted: 1994-12-20
Abstract: A series of bags are fabricated using a continuous, high-speed bag-forming process in which an elongated section of flattened film tubing is longitudinally conveyed toward a receiving  station  in  which  the  formed bags  are  suitably packaged.    As  the  flattened  tube  is  moved  toward  the receiving station, elongated plastic film tie elements are sequentially formed and welded along relatively large area end portions thereof to at least two layers of a side edge portion  of  the  flattened  tube  at  longitudinally  spaced locations thereon adjacent the upper end locations of the individual bags, the resulting free end portions of the tie elements  overlying  the  flattened  tube.    Each  of  the resulting  integral  tie  elements may be  looped around an upper end portion of  its associated bag and then firmly pulled to close the bag, the resulting loop being tightened either by first passing the free end portion of the tie element  therethrough  or  by  first  passing  the  free  end portion through an aperture formed in the tie element-bag weld area.   In either case the relatively large, multiple layer weld area which secures the tie element to a side edge portion  of  its  bag  provides  sufficient  strength  so  that separation  of  the  tie  element  from  its  bag,  during tightening  of  the  loop  around  the  upper  bag  end,  is effectively prevented.

Abstract: ABSTRACT OF THE DISCLOSURE:     Disclosed is an improvement of gaslighter structure which has,  in the hollow cylinder space at the rear portion of the housing, a push rod having hooks integrally connected to its op-posite sides.   The push rod  is spring-biased upwards, and  is pushed against the support piece of the cap, thereby permitting the cap to click shut and open.  This arrangement permits neces-sary parts including a spring to be assembled in a cap pivot-and -latch simply by thrusting them in the rear space of the housing. This reduces the difficulty which otherwise, workers would en-counter in assembling parts including a resilient element in a relatively small space.  Also, the work of pivoting the cap to the housing can be advantageously separated from the work of as-sembling pivot-and-latch parts.

Abstract: ABSTRACT            The invention relates to a syringe (1) comprising a con-tainer (2), a needle (3) capable of co-acting with one end of the container, a plunger (4) which is arranged in the container and which sealingly co-acts with the inner surface (2c) thereof, and a rod-shaped element (5) which co-acts with the plunger (4) and which is arranged for reciprocating movement relative to the container (2), such that movement of the element from the one end (2a) in a first direction (P1) enables, the container (2) to be filled with injection liquid, while linear movement in the opposite direction (P2) causes liquid in the container to be discharged therefrom through the needle (3).  Provided between the plunger (4) and the element (5), for their mutual co-action, is a screwthreaded means (6) which holds the plunger (4) firmly to the rod-shaped element (5) when the element moves in the first direction (P1) but which adopts an inactive state when the element (5) is moved in the opposite direction, therewith rendering refilling of the container impossible.          It is suggested that Figure 1 is published together with the abstract.

Title: Method of blending textile fibers

Granted: 1993-07-06
Abstract: A b s t r a c t The invention relates to blending of individual fibre components in accordance with  the properties of a required  intermediate product such as a card silver, or a required end product such as a yarn.            The blending process is as follows: fibre bales (2) are combined Into component  groups  and  the  fibre  components  in  the  groups  are accurately supplied by metering devices  (11) to a blender, in which the components are homogeneously mixed.            The product from the blender is then cleaned in a cleaning station (60) and delivered for processing to a card (63).   After  leaving  the  card,  the sliver  is  tested  in a  colour-testing device  (65) and the corresponding signal 18 delivered to a control system (7; 7.1; 7.2; 44) which primarily controls the component blend and secondarily is also corrected by a colour system so that the primary   blend control is altered until the colour at the outlet of the card again coincides with the colour in the card silver.         The card silver is also tested for fibre fineness  (MICRONAIR) using the fibre-fineness testing device (66), and a corresponding signal is delivered to the aforementioned control system.   The aforementioned component  blend is also adjusted by means of  this signal,  if the fineness deviates from a preset value.            A third signal (81) comes from the card control system  (64).   This signal  indicates  the  output  (kg/h)  to  the  aforementioned  control system, in order to control the amount delivered by the extraction devices (20, 23).
