Abstract: A demand defrost controller (30) for a heat pump 
(10). The controller (30) compares the temperature of an 
outdoor heat exchange coil (14) with an enable 
temperature. A timer is activated when the coil 
temperature is less than the enable temperature. When the 
timer senses the compressor (20) has a run for a 
predetermined time the controller (30) checks outdoor and 
coil temperatures to determine if a defrost cycle of the 
heat pump (10) should be conducted. A defrost cycle is 
achieved by reversing refrigerant flow in the heat pump 
system for a predetermined period or until the outdoor 
heat exchange coil (14) has been heated to a termination 
temperature.

Title: Bolt anchored by impact
IPC: F16B13/08
Filed: 1988-12-23
Abstract: Bolt anchored by impact for insertion in undercut drilled holes in masonry are known, which have an expanding body supported on the base of the drilled hole, onto which an expanding sleeve can be driven. These conventional bolts anchored by impact cannot be used in drilled holes which are not undercut, at least in relatively hard masonry. In order to provide a bolt anchored by impact which can be inserted in both undercut drilled holes as well as drilled holes without an undercut, in a positively locking manner, there is provided on the shank end of the bolt anchored by impact a plate with a cut-out whose side limbs can be spread in a V-shape by driving in an expanding body. The narrow edges of the plate can in this case bury themselves in the wall of the drilled hole and produce a positively locking connection to the masonry. <IMAGE>

Patent EP-0325438-A3 (EP)
IPC: C10G11/18
Filed: 1989-01-18
Abstract: Lower alkanes are converted to olefins in a 'third bed' 
external catalyst cooler (ECC) in which hot catalyst, from a first 
regenerator ('second best') operating in conjunction with a fluid 
catalytic cracker ('first bed'), thermally cracks and dehydrogenates 
the alkanes. Because this is an endothermic reaction, the catalyst 
is autogeneously cooled before it is recirculated to the FCC 
regenerator. The cracking catalyst is the catalyst of choice in the 
FCC reactor. Maximum conversion of alkanes to olefins is sought, and 
can be maintained because the FCC regenerator burns the coke made 
during alkane dehydrogenation. The olefins produced are then 
oligomerized in an oligomerization reactor ("fourth" bed) operating 
in conjunction with a second regenerator ("fifth" bed) to produce a 
gasoline range stream. The interrelataed operation of this 
combination of five fluid beds is tailored to convert all available 
low value alkanes, to olefins which are generally in high demand for 
several uses, particularly to make high value gasoline.

Title: Method for measuring density of newtonian and non-newtonian fluids
IPC: G01N11/12
Filed: 1989-03-14
Abstract: A method for determining the density of a liquid 
using a falling needle viscometer wherein the 
viscometer (10) includes a vertical cylinder (12) which 
is filled with the liquid the density of which is to be 
determined. Using a funnel (24) at the top of the 
cylinder, a first needle (54) having a known density is 
allowed to fall through the liquid in the cylinder. 
The time taken for the needle to fall between two marks 
(22a,22b,22c,22d), or transducers, spaced on the 
cylinder a known distance apart is measured, from which 
the velocity of the needle through the liquid is 
calculated. Then a second needle having the same 
dimensions as the first and a known density different 
from that of the first needle is allowed to fall 
through the liquid. The time taken for the second 
needle to fall between the two marks on the cylinder or 
transducers is measured and the velocity of the second 
needle through the liquid is calculated. Using the 
densities of the two needles and the velocities of the 
needles through a Newtonian liquid the density of the 
liquid is calculated using disclosed equations. Using 
the densities of three needles and the velocities of 
the needles through a non-Newtonian liquid, the 
density of the liquid can be calculated using disclosed 
equations.

Title: Simulated color imaging using only two different colorants/toners
IPC: H04N1/52
Filed: 1989-11-28
Abstract: Simulated color imaging using gray level patterns produced from two 
differently colored materials by employing fine patterns of dots. The dots blend with the 
background and yield a gray or colored appearance when seen from a distance. The 
imaging process utilizes ink pattern designs in conjunction with registered two-color 
imaging to thereby form simulated color images. Digital information representing two sets 
of gray-level producing patterns, set A for color A and set B for color B, is electronically 
stored in computer memory. The patterns in set B are complementary to those of set A. An 
apparent or simulated color image is produced by overlaying, combining or juxtapositioning 
a pattern from set A with a complementary pattern from set B, the combined image being 
subsequently rendered visible using two different colorants. A gray level pattern is 
produced for each elemental area of an original image.

Patent EP-0345215-A3 (EP)
IPC: G01N25/68
Filed: 1989-05-16
Abstract: A novel method is proposed for determining the dew point of a gas by means of a light ray reflected at a dew-point mirror (3). For measurements of fairly low dew points, in particular at temperatures of -50 DEG C to -95 DEG C, the dew-point mirror (3) is first exposed for a short time to a gas having a high water content. This achieves the result that an initial, fairly thick dew layer which appreciably shortens the measurement time is built up on the dew-point mirror (3). To carry out this method, a dew-point measuring system is proposed which has a gas valve (24), an injector pump (25) and a moistening unit (26) in a secondary circuit (23). A hygroscopic polyamide hose which ensures maintenance-free moistening of the gas by water molecules diffused into it has proved particularly advantageous. <IMAGE>
