Title: Adjustable shutter for containment of small electronics components in tape feeders
Inventor: SOTH HENRY J
IPC: B65B15/04
Filed: 1990-04-11
Abstract: ABSTRACT OF THE DISCLOSURE           A feeder mechanism for a pick-and-place machine with an adjustable shutter mechanism is disclosed.  The components are contained within pockets formed in a reeled tape.  The shutter mechanism includes a pair of spring blades that cover the pocket, but are spread apart by the vacuum tip when the spindle is lowered.  In this way, the shutter can maintain the component in the proper position for pick-up while allowing the vacuum spindle to access the component, which,  in turn,  maintains  proper attitude of  component while the blades are retracted.

IPC: F16F13/00
Filed: 1990-07-26
Abstract: A hydraulically damped mount includes both a fluid overflow opening (6) and a damping opening (5) arranged in parallel between a fluid working chamber (4) and an equalizing chamber (7). In the overflow opening (6) there is provided a pressure relief valve (8) which can be activated by the differential pressure between the working chamber and the equalizing chamber. This valve contains a control element (10) and an opposing counter stop (11) which the control element can contact with a tight fit and which it can pass by in case of excess pressure. When inactive, the control element (10) is spaced apart from the counter stop (11) at such a distance that a contact with the counter stop (11) is impossible when acoustically active vibrations are introduced.

Title: Process for the manufacture of a press shell and device for the application of the process
Inventor: STEINER KARL
IPC: D21F3/08
Filed: 1990-08-14
Abstract: ABSTRACT OF THE DISCLOSURE    A process for the manufacture of a continuous press shell that is liquid-tight and smoothed on its inside, and which can be used as a press element in a dewatering press is provided.         The press shell consists of a continuous wire belt which on its outside is coated with a plastic.  Upon the smoothing of its outside, the coated press shell is turned, so that for the use of the press shell its smoothed surface will be on its inside.          For turning the press shell, the one continuous edge of the press shell is first turned inward and attached to a traction device.  Next, an adjoining and as yet unturned section of the press shell is held back on its outside, by means of vacuum, on a fixed guide device.  Lastly, the traction device, along with the edge of the press shell attached to it, is pulled through the interior of the press shell.
Patent CA-2023308-A1 (CA)
Inventor: HOLLANDER MILTON B
IPC: G01R33/12
Filed: 1990-08-15
Abstract: A  superconducting wire is produced by the surrounding of  a  superconductive  material  core with an intermediate compressible  insulating layer and an outer malleable layer and  then drawing said composite structure through a series of  dies to reduce the diameter of the wire on the order of 400 to 10,000 times  or  by reducing the superconductive core  material  to  the desired  wire  size by passing it through  a  series  of  dies  to reduce the diameter of the wire  on  the order of 400 to 10,000 times and then coating the  wire  with a noncompressible insulating layer and then placing  an  outer  malleable layer over the insulated wire and  drawing  this  through  dies  to snuggly fit the outer layer    onto    the    insulated    wire.    This wire's superconducting characteristics   are  not  intended  for carrying  high  levels  of currents so the reduction of the available   current   carrying   cross   section   by   the introduction  of  the insulating layer is not of concern in the  applications  for  the  wire. Low and high temperature high  level  current-carrying  superconductors  lose  their superconductivity    with   changes   in   their   critical temperature   and  critical  magnetic  field.   A  loss  in superconductivity     in     a     high    current-carrying superconductor   can   cause   irreparable  damage  to  the superconductor   and   its   physical   environment.   Said superconducting  wire  when  used  in  assembly with a high current-carrying  superconductor   provides  a  means  for detecting  changes in the critical temperature and critical magnetic   field  of  the  current-carrying  superconductor before  the  superconducting  properties  are  lost so that measures can be  taken  to  correct  the  changes  in the critical temperature and the critical magnetic field.

Title: System for controlling the opening and closing of shield plate of helmet
Inventor: KAMATA EITARO
IPC: A42B3/24
Filed: 1991-05-29
Abstract: ABSTRACT OF THE DISCLOSURE    An elongated hole is provided in a shield plate to extend in a direction to open and close the shield plate, and a stopper pin is fixedly mounted on a cap body and adapted to be fitted into the elongated hole, so that the shield plate is restrained from opening more than a predetermined opening angle by abutment of the stopper pin against one end wall of the elongated hole. In addition, a cam member is mounted on the cap body for pushing up an end edge of the shield plate to permit the slipping of the stopper pin out of the elongated hole. These ensure that the shield plate can be restrained to a position corresponding to the predetermined opening angle, thereby preventing any clouding of an inner surface of the shield plate, while preventing the inadvertent opening of the shield plate by  wind pressure.

Abstract: ABSTRACT OF THE DISCLOSURE          Novel  acellular  anti-pertussis  vaccines  are  described,   which comprises  a   non-toxic  double mutant of  pertussis  toxin  (PT), filamentous  haemagglutinin  (FHA) and the 69  kilodaltons  protein (69Kd)  taken  alone  or in combination  with  the diphtheria  and tetanus anatoxin. The completely non-toxic double mutant of the  PT is   characterized by the fact that is comprises in the amino  acid sequence of the S1 subunit the substitution of Glu 129 and of   one of  any other amino acid of the subunit, whose substitution  brings about  a  decrease in toxicity, by natural  amino  acids.  Moreover there   are   described   purification   methods   for,   and   the characterisation  of  the FHA and  the 69 Kd protein  expressed  by transformed B. pertussis W28-9K/129G strains, which produce the  PT double  mutant and by transformed B.  pertussis W28-  Tox which  do not  produce the PT.  These proteins are particularly suitable  for preparing  safer  and  more  immunogenic  acellular  anti-pertussis vaccine.

Abstract: It has been found that surface reactions with basic materials such as amines found in the processing environment during lithographic processing contribute to a loss of linewidth control for resists such as chemically amplified resists, This loss in linewidth  results from the reaction of the acid generated by exposing radiation with, for example, the amine resulting in a lack of chemical reaction where such reaction is desired. The problem is solved in one embodimentby employing an acid containing barrier layer on the resist.
