Title: Adjustable hydraulically damped mount for a piston engine
Inventor: FREUDENBERG ULRICH
IPC: B60K5/12
Filed: 1990-07-25
Granted: 1994-05-31
Abstract: ABSTRACT     A hydraulically damped support such as a piston engine motor mount has a liquid filled working chamber which communicates with a compensation chamber through a connecting passage.  The effective length of the connecting passage may be controlled by an adjustable lateral discharge valve which is positioned intermediate the discharge ends and in the wall of the passage. The distance of the lateral discharge valve from these discharge ends is selected so that when the valve is open the volume of liquid contained in the effective length of the passage, is caused to reciprocate in an oscillatory movement which is substantially in phase with the vibration of the load bearing support of the mount (at idle motor speed).  When the valve is closed the effective length of the passage is increased and lower frequency vibrations (stutter frequencies) can be damped, with the oscillatory movement in counter phase to that of the load bearing support.

Title: Process for preparing 1, 1, 1-trifluorochloroethane and 1, 1, 1, 2 tetrafluoroethane
Inventor: KOYAMA SATOSHI
IPC: C07C17/20
Filed: 1991-03-12
Granted: 2002-05-07
Abstract: The present invention is directed to a process for preparing 1,1,1-trifluorochloroethane by reacting, in a gas phase, trichloroethylene and hydrogen fluoride. When the reactant gases are diluted with a gas which is inactive to the reaction, it is very easy to control the reaction temperature, and when gas generated from the reaction of 1,1,1-trifluorochloroethane and hydrogen fluoride is used as a diluent gas, generation of 1,1-difluoroethylene is suppressed to a very low level while not influencing the reaction between trichloroethylene and hydrogen fluoride. The 1,1,1-trifluorochloroethane prepared by the process of the present invention is used as a refrigerant.

Title: Color picture tube having improved shadow mask-frame assembly support
Inventor: RAGLAND FRANK R JR
IPC: H01J29/02
Filed: 1991-03-14
Granted: 1993-10-12
Abstract: ABSTRACT        An improved color picture tube includes an evacuated glass envelope having a rectangular faceplate panel. The panel includes a shadow mask assembly mounted therein by support means located at peripherally spaced positions within the panel. The support means provide compensation for thermal expansion of the shadow mask assembly. The compensation is a movement of the shadow mask assembly toward a screen of the tube as the shadow mask assembly expands. The support means at each of the spaced positions includes a stud attached to the glass envelope, a spring having an aperture therein engaging the stud, and a plate welded between the spring and the shadow mask assembly. The improvement comprises the combination of the spring being angled with respect to the shadow mask assembly to provide approximately half of the required compensation, and the plate being constructed of bimetallic materials and having appropriate thickness and length to provide the approximately remaining half of the required compensation.

Title: Phase controlled capacitor for series compensation of a high voltage transmission line
Inventor: CHADWICK PHILIP
IPC: H02J3/18
Filed: 1991-04-25
Granted: 1999-12-07
Abstract: A compensating circuit arrangement for a power transmission system for rapidly inserting capacitance into a transmission line for desired portions of cycles of the operating frequency of the system, has first anti-parallel connected thyristors in series with a capacitance and second anti-parallel connected thyristors in parallel with the series connected first thyristors and the capacitance. A control responsive to a variable in the system, and related to system reactance, switches desired thyristors on at desired times during a cycle of operating frequency to introduce controlled amounts of capacitance into the power transmission system. In one form of the invention the control is responsive to the angle delta which is the angle between the voltage at the source end of the power transmission system and the voltage at the load end.

Title: Reversible street hockey goaltender's blocker
Inventor: CHIH HUANG YING
IPC: A63B71/14
Filed: 1992-04-15
Granted: 1996-08-06
Abstract: A street hockey goalie's blocker is described, which permits the blocker to be used on either the left hand or the right hand.  Thee blocker has a generally planar rectangular blocking pad having a blocking side and an inner side, as in the prior art.  Also as in the prior art, a member is provided on the inner side of the blocking pad, which, when attached to the blocking pad, forms a sleeve.  The member has an integral thumbguard extending therefrom.  However, the sleeve (member) is removably attached to the inner side of the pad, instead of being sewn thereto, and is reversible.  Removing the sleeve, turning it over, and then reattaching it in effect changes the position of the thumbguard from one hand to the other.  A thumb strap is provided, as in the prior art, but instead of being sewn to one side of the thumbguard, it can be positioned on either side of the thumbguard, to allow for the reversibility of the thumbguard.  In the preferred embodiment, strips of VELCRO (trademark) fastening material are used to attach the sleeve to the pad.  A retention strap is used to assist in holding the sleeve in place, once it has been positioned using the VELCRO strips.

The protein named protein D is an Ig receptor for human IgD and has an apparent molecular weight of 42,000. Protein D can be detected in all of 116 encapsulated and non-encapsulated isolates of H. influenzae studied. The protein from all strains shows in addition to the same apparent molecular weight immunogenic similarities since protein D  from all strains interacts with three different mouse monoclonal antibodies and monoclonal human IgD. A method for purification of protein D is described. Cloning of the protein D gene from H. influenzae in E. coli is described as well as the nucleotide sequence and the deduced amino acid se-quence.

Abstract: Gobs of molten glass fall in succession into a scoop (8) which can be swivelled about a vertical axis and which supplies gobs to subsequent multiple delivery systems (3), for example of an I.S. glassware forming machine. The gobs travel along a path of movement (13) from the scoop (8) in free flight to a sliding member (9), from this in free flight to a trough (10), and from this again in free flight to a deflector (11) which is downwardly curved. The deflector (11) delivers the gobs so that their longitudinal axis lies coaxially with respect to, the longitudinal axis (31) of a mould (4) which is to be charged. The sliding member (9) is supported to be fixed relative to the machine. The trough (10) has its upper end (18) supported by means of a universal joint (38) on the sliding member (9). The lower end (23) of the trough (10) is guided in a vertical chute (42) of the deflector (11) and can be raised and lowered by means of an adjustment device (43).

Title: Method for producing heat-recoverable articles and apparatus for expanding/shrinking articles
Inventor: MCGAFFIGAN THOMAS H
IPC: B29C61/08
Filed: 1992-04-24
Granted: 2001-10-16
Abstract: A method of producing a heat-recoverable plastic article such as a tube (1) by deforming the article from a heat-stable con-figuration (1a) to a heat-unstable configuration (1b). The heat-unstable configuration will return to the heat-stable configuration when the article is heated to above the heat recovery temperature. The article is heated such that the article is at a temperature no lower than the heat recovery temperature during the deforming step by lossy particles (2) dispersed in the article or in a tool (4) used in the deforming step. The lossy particles allow auto-regulated heating of the article since the particles cannot be heated be-yond their Curie transition temperature when subjected to an alternating magnetic field. These particles are preferably ferrites. Alternatively, the tool can include a braided mesh tubing (12) of a ferromagnetic alloy wire. The article is cooled in the heat-un-stable configuration to a temperature below the heat recovery, temperature while preventing the article from returning to the heat-stable configuration. The tool can be a mandrel (8), expandable tube (10) or caterpillar (4).
