Granted: 1993-07-27
Abstract: ABSTRACT OF THE DISCLOSURE      A removable closure cover for a drinking vessel such as a cup or mug has an outer cover for attachment to the mouth of the vessel, with an aperture adjacent the edge through which a user may drink.  An inner cover secured to the outer cover is selectively moveable into opening or closing relation with the aperture.  While useable with insulated plastic drinking cups, the closure cover also may be used with traditional mug or cup forms, to enable tranportation of a hot drink in sealed, in-sulated relation, thus extending the utility of the tradition-al,  non-disposable  mug,  in  an  ecology  promoting  fashion. Manipulation of the cover provides controlled ventilation of the container and permits modulation of the cooling time for a hot drink contained therein.

Title: Multi-pass roll crusher
Inventor: SZAZDI JOHN S JR
IPC: B02C23/38
Filed: 1991-07-30
Granted: 1999-08-03
Abstract: Disclosed is an apparatus and a method for the comminution of brittle material in a roll crusher.          The method comprises the steps of introducing fresh material feed into a roll crusher  which is divided into two distinct feed inlet zones which are at least one  initial  feed  inlet  zone for  said fresh  feed material and at least one secondary feed inlet zone for feed which has been stressed at least once by said roll crusher.  Each initial feed inlet zone and each secondary  feed  inlet  zone  directs  feed  into, respectively, a corresponding initial feed crushing zone  and  secondary  feed  crushing  zone.   In  the invention, fresh feed material is introduced into the roll crusher only in the initial feed inlet zone(s) whereby it is stressed at pressures sufficient high to cause the formation of at least some agglomerates.          The product thus  formed  is  recirculated,  without causing  any  substantial  disintegration  of  the agglomerates,  into  the  roll  crusher  through  the secondary feed  inlet  zone whereby  it  is  further stressed  at  pressures  sufficient to  cause  the formation of at least some agglomerates.

IPC: H05K3/42
Filed: 1992-03-24
Granted: 2002-12-31
Abstract: Copper through-hole printed wiring boards are produced by forming an etching resist layer on the copper plating of a double sided copper clad laminate.      The etching resist layer is formed after a negative resist pattern is applied to both sides of the laminate, and the laminate then dipped in a solution containing at least one salt of 2-alkylbenzimidazoles, 2-alkylalkyl-benzimidazoles, 2-phenyl-benzimidazoles and 2-phenyl-alkylbenzimidazoles. After the resulting etching resist layer is selectively removed. with an alkaline aqueous solution, in accordance with the predetermined pattern of the wiring, the exposed copper plating is etched off with an alkali etchant. According to the process of the present invention, remarkable advantages such as increased productivity, lower production costs, reduced toxic substances in waste water, and a high reliability can be obtained in the production of copper through-hole printed wiring boards.

Title: Local oscillating frequency synthesizer for use in a tdma system
Inventor: JOKURA JUN
IPC: H03L7/18
Filed: 1992-07-28
Granted: 1996-01-16
Abstract: A local-oscillating-frequency synthesizer includes a pair of synthesizers, one being used for synchronizing the frequencies of the communication channels used for transmission and reception slots, and the other for synchronizing the frequencies when the electric-field level of the other station is monitored and information is read out between idle slots, i.e. slots other than the transmission and reception slots. Therefore, without using a high-speed frequency-switching synthesizer such as a direct digital synthesizer or the like, synchronization of the frequencies by switching is achieved in a short period of time, and a local-oscillating portion which is low in power consumption is obtained.

Abstract: An end of stroke cushion for a linear hydraulic motor.  A piston-cylinder unit includes a cylinder body (42) reciprocally slidable on a piston rod (40) having a piston head (64) which defines working chambers (82, 84) within the cylinder body (42).  The piston rod (62) is tubular and includes a plurality of sidewall ports (P1-P7). A radially-expandable annular valve ring (106) normally snugly surrounds the piston rod (62) and during axial movement of the cylinder body (42) relative to the piston rod  (62),  the valve ring  (106)  will move axially relative to the sidewall ports (P1-P7) in the piston rod (62). Pressure introduction to the working chamber (84) through the sidewall ports (P1-P7) of the piston rod (62) and against the valve ring (106) radially expands the valve ring (106).  This allows oil flow to move into the working chamber (84) such that when the chamber (84) expands, the cylinder body (42) and valve ring (106) will move axially relative to the sidewall ports (P1-P7),  successively uncovering the ports  (P1-P7)  during movement.  Removal of fluid from the working chamber (84) will cause oil movement out from the chamber (84), through the sidewall ports (P1-P7) into the tubular piston rod (62) such that when the linear motor (10) approaches the end of its stroke, the valve ring will close the sidewall ports (P1-P7) in the piston rod (62) which allows oil flow out from the working chamber (84) in succession.
