IPC: A61F13/15
Filed: 1987-04-10
Abstract: The present invention provides a distinctive absorbent 
garment (10) which comprises a backsheet (12) having waist­
band portions (18) at each longitudinal end thereof, and inter­
mediate portions (20) interconnecting the waistband portions 
(18), and marginal portions (26) along each lateral side edge 
of the backsheet (12). A liquid permeable liner sheet (14) is 
located in facing relation with the backsheet (12), and an 
absorbent body (16) is located between the backsheet (12) 
and liner sheet (14). The absorbent body (16) delimits waist­
band sections (52) at each longitudinal end thereof, delimits 
an intermediate section (54) interconnecting the waistband 
sections (52), and delimits a marginal contour (56) at each 
lateral side edge of the absorbent body (16). Each marginal 
side contour (56) has at least one collapsible notch section 
(58) formed therein. A fastening mechanism (70) is connected 
to the garment (10) for securing the garment (10) on a wearer.

Patent EP-0258671-A3 (EP)
IPC: G11B20/10
Filed: 1987-08-06
Abstract: A read channel circuit includes a high frequency filter (14) 
and a pair of differentiators (16, 18), one of which is a high 
resolution differentiator (16) and the other of which is a low 
resolution differentiator (18) intentionally adjusted to per­
form its differentiation function imperfectly. Comparators 
(32) serve as zero crossing detectors for the high and low 
resolution signals. The comparator for the low resolution 
path provides the data input to a flip-flop (34). The compara­
tor for the high resolution path has its output processed by an 
exclusive OR gate (38) and a delay circuit (44) before being 
applied to the clock input (46) of the flip-flop. The high-­
resolution and low-resolution paths are combined in the flip-­
flop (34), whose digital output faithfully reproduces the bi­
nary information received by the read head by deriving 
timing from the high-resolution path and by effectively dis­
criminating against artifacts in the read head's signal which 
would result in spurious transitions in the read channel's 
output were it not for the imperfect differentiation provided in 
the low-resolution path.

Patent EP-0274656-A3 (EP)
Title: Catch device
IPC: E06B9/82
Filed: 1987-12-05
Abstract: The invention relates to a catch device against undesired rolling of a roller door. A first worm wheel (2), which is connected to the roller door shaft (4) in a rotationally fixed manner, and a second worm wheel (5), which is mounted rotationally movably with respect to the first worm wheel (2) and the roller door shaft (4), mesh with the driving worm (1). The second worm wheel bears driver elements (7), which displace the blocking bodies (8) within a frictional locking mechanism (6-10) between the supporting surfaces (9, 10). During normal operation, the blocking bodies (8) are located approximately in the region of the centre of the supporting surface (9), so that the roller door shaft (4) runs freely within the stop (6) fixed to the housing. In the event of disturbance, for example wear of the teeth of the first worm wheel (2), a rotation of the two worm wheels (2, 5) relative to each other leads to a positional change of the driver elements (7) and thus of the blocking bodies (8) so that the roller door shaft (4) is blocked by means of the blocking bodies (8) directly against the stop (6) which is fixed to the housing, without the blocking force having to be transferred from the second worm wheel (5).

Title: Liquid removal enhancement
IPC: B01D53/26
Filed: 1987-05-15
Abstract: An improved process for removing free liquid from a hydrocarbon-rich gas stream is disclosed. Liquid is injected into the gas stream upstream of a chiller and downstream of an acid-gas removal system and any equipment that may affect the water content of the gas stream: compressors, columns, additional knockout drums, heat exchangers or the like. This enhances heat and mass transfer in a manner that both minimizes the formation of small droplets and encourages the coalescence of small droplets in the chiller. As a result, small droplets which would normally pass through a knockout drum and a standard mist eliminator are increased in size, prior to their arrival at a vapor-liquid separator to larger drops which are easily removed by the vapor-liquid separator, and the mist eliminator.

Abstract: A discrete transform cosine circuit utilizing symmetries of the cosine 
matrix of coefficients to allow all multiplications to be done by "constant 
multipliers" comprising combinations of look-up tables and adders. Transform 
coefficients are developed by dividing each into a sequence of blocks of 
preselected size, the information in the blocks is sorted to develop a specific 
order and the reordered blocks are applied seriatim to a first one-dimensional 
cosine transform circuit 20 employing the constant multipliers. The output of 
the first cosine transform circuit is applied to a transposing memory 30 and 
then to a second cosine transform circuit 40 that also employs "constant 
multipliers".

folic acid, separating the new diastereoisomers, recovering 
the desired new diastereoisomer (6R or 6S) corresponding 
to the desired (6R or 6S) diastereoisomer, and converting 
the substantially pure new diastereoisomer recovered into 
the corresponding diastereoisomer.

Title: Improved adsorptive purification process
IPC: B01D53/04
Filed: 1988-03-09
Abstract: A vapor phase purification process using a fixed adsorbent bed containing a zeolitic molecular sieve comprising zeolite crystals having the faujasite crystal structure and containing cations having a higher charge density than sodium cations, whereby regeneration of the bed is accomplished using purge gas streams at temperatures of from 55 DEG C. to 100 DEG C. The ability of the zeolite adsorbent to be regenerated at relatively very low temperatures permits the use of heat energy normally to low in intensity to be utilized and is thus usually waste energy.

Title: Methods and compositions for tenderizing and upgrading the sensory qualities of red meat
IPC: A23L13/00
Filed: 1988-03-15
Abstract: The present invention relates to methods, compositions, and apparatus for treating and upgrading the tenderness and sensory qualities of fresh red meats. The present invention provides a mechanism whereby low grades of meat may be made tender, flavorful, and juicy without significantly increasing saturated fat content. This is accomplished by injecting the meat with appropriate injectates. Such injectates may include unsaturated vegetable fats such as corn oil, water, and even beef tallow or other saturated fats. It is presently preferred to include a binder in the injectate such that a substantial portion of the injectate is retained within the meat even after cooking. Failure to provide a binder often results in a drier tasting meat product. The present invention also teaches the construction of an apparatus which allows injection in a sanitary manner. Additionally, injection can be accomplished such that the meat product may have the appearance of natural marbling.
