Abstract: ELECTRIC MODULE LATCH ASSEMBLY   ABSTRACT OF THE DISCLOSURE        An electric module latch assembly (2) includes a latch handle assembly (4) mounted to the module (6) and a keeper (8) mounted to a housing (10).  The latch handle assembly includes a U-shaped handle (18) having an elongate lever (42) pivotally mounted to one leg (22) of the handle at a latch end (46) of the lever.  The latch end has a cam surface (64) which engages the keeper.   The outer,  catch end  (44)  of the lever is configured to engage a spring-loaded catch button (50) mounted to the other leg (20) of the handle.  A disenable switch pin (72)  is mounted to the handle to resiliently engage the underside (80) of the lever so that when the lever is in the latched position, the lever keeps the disenable switch pin depressed.  The pin is long enough to engage an enable switch (96)  within the housing when so depressed.   The initial movement of the lever away from  (and the  final movement towards) the handle permits the electrical connectors (12, 14) coupling the module and housing to be disconnected  (and connected) under no-load conditions.  The keeper is mounted to the housing so that it can move a short distance towards and away from the housing while being spring biased (70) towards the housing.

Title: Foam type carpet cleaner
Inventor: MACDONALD DONALD A
IPC: A47L11/32
Filed: 1990-07-04
Abstract: ABSTRACT            The invention is directed to improvements in foam type carpet cleaners and, more particularily, to the production of a relatively dry water-detergent mixture foam which is producted by applying drops of the mixture into an airstream duct in which is located a rotating propeller, or fan blade, driven by the airstream, the propeller contacting the drops and producing a fine droplet dispersion of the mixture, which dispersion is blown, by the same air stream, through a fine mesh screen to produce a foam which is applied, to a carpet to be cleaned, by a foam spreader.  The foam is then brushed through the nap of a carpet by a rotating brush associated with the spreader.  A debris collector is preferably associated with the brush to pick up carpet debris and spent foam.

Title: Radome having integral heating and impedance matching elements
Inventor: LOPEZ ALFRED R
IPC: H01Q1/42
Filed: 1990-10-03
Abstract: ABSTRACT      An antenna radome, suitable for use with high precision, environmentally sensitive array antennas, includes a dielectric sheet formed to protect the antenna from environmental conditions and a series of conductors fixed on the sheet in a certain pattern so that the sheet with the conductors provides a lower reflection coefficient to electromagnetic waves at the antenna's operating wavelength than in the absence of the conductors.  Current is caused to flow through the conductors, thus generating heat in areas of the dielectric sheet where the conductors are fixed.  Accordingly, ice formation on the protective dielectric sheet can be prevented while the antenna array is operational, and accurate antenna performance is ensured.  Further, the dielectric sheet presents a significantly lower reflection coefficient at the operating wavelength than radomes in which a conventional grid of heater wires is provided for melting ice.

Patent CA-2034471-A1 (CA)
Inventor: MCDANIEL DAVID L
IPC: H04N5/369
Filed: 1991-01-17
Abstract: A image detector includes an array of photodetectors arranged in n rows and m columns with at least a portion of the photodetectors in each column being selectively connected to a common column output signal line by a selector means. The image information is read out of the photodetectors by sequentially selecting groups of rows starting with a row near the middle of the array and then sequentially selecting other groups of rows on alternate sides of the array middle. As image data is read out of the photodetectors in the selected row group, groups of column output lines are coupled together to provide a combined output signal. This readout technique provides a reduction in the image data and reduces the likelihood of signal degradation for the central portion of the image.
