Title: Multi-function rotary dial system including timer setting feature
Inventor: WAKAHARA TATSUYA
IPC: G11B15/10
Filed: 1985-12-24
Granted: 1992-12-08
Abstract: ABSTRACT OF THE INVENTION         In  a  multi-function  video  tape  recorder system, a manually operable rotary dial can be used in place of a large number of dedicated manual switches, etc.  to make selections from multiple-chocie lists and to assign numerical values for timing, etc.  The rotary dial is journalled on a fold-down section of the video tape recorder's front console and its manually-actuated rotation   is   monitored   by   optical   sensors.     A microprocessor receives the output of the sensors and so can derive the angular position and speed and direction of rotation of the rotary dial, which may all serve as input parameters.   In addition, a ring may be included in  the  rotary  dial  assembly,  the  ring  be  pivotably slightly relative to the rotary dial itself to provided an addition dimension of information input. The rotary dial can be used to input date and time information for both  clock  setting  and  timer  setting operations,  to select  a  televison  channel  for  recording  or  direct reception,  to  select  the  speed  and  mode  of  video playback and/or to control  the rate and direction of frame advance.

Title: Multi-position articulated arm lockable adjustable holder
Inventor: STRAETER FRITZ
IPC: F16M11/10
Filed: 1986-09-03
Granted: 1991-04-16
Abstract: ABSTRACT         A holder for use with desks, drafting tables, CRT work stations, and the like, said holder consists of a multisection boom-type arm that is hinged to a base, the boom arm having at its free end a holder plate or the like.  The sections of the boom arm are hinged to each other and the holder plate is hinged onto the boom arm.  Manually adjustable, friction-type locking devices that control movement of the components are flexibly connected are associated with these pivoting joints.  So that manipulation and adjustment is rendered far simpler, it is proposed to provide a handle that acts through an intermediate locking device on several of the pivot joints and is arranged close to the holder plate.

Title: In-tank fuel pump assembly for fuel-injected engines
Inventor: BUCCI GEORGE H
IPC: F02M37/00
Filed: 1987-08-14
Granted: 1992-04-07
Abstract: ABSTRACT OF THE DISCLOSURE      An in-tank, fuel pump assembly for fuel-injected engines is provided which includes a reservoir (10) having a supply port (32) for supplying fuel to  the  engine and a return port  (36)  for receiving fuel returning from the engine.  Within the reservoir (10) are 1) an electrically-operated, high pressure pump (26), 2) a jet pump (30) located at the bottom of the reservoir (10) for entraining  fuel  into  the  reservoir (10),  3)  a  valve  (34) associated  with  the  return  port  (36),  and  4)  a  valve  (38) associated with the supply port  (32).   The output of the high pressure pump (26) is routed to the jet pump (30) and to the two valves  (34,38) whereby when the high pressure pump (26)  is not operating,  both valves  (34,38)  are  closed,  and when  the high pressure pump (26) is operating, both valves (34,38) are open and the jet pump (30) entrains fuel into the reservoir (10).  The jet pump (30) is sized to entrain more fuel into the reservoir (10) than leaves the reservoir (10) through the supply port (32) thus producing a net flow of fuel from the bottom to the top of the reservoir (10).  As a result of this flow and the arrangement of the various components of the assembly, cool fuel from the main fuel tank is supplied to the engine rather than hot fuel returning from the engine through the return port (36), thus avoiding the hot fuel problems experienced in the prior art.

Title: Rotary end face seal assembly
Inventor: JANZEN PETER
IPC: F16J15/38
Filed: 1987-08-27
Granted: 1999-04-13
Abstract: An improved rotary end face seal assembly used singly or in combination with other seals, preventing escape of a contained pressurized medium, gas or liquid, through the annulus between a stationary housing and a rotating shaft, comprises a rotary assembly and a stationary assembly.  One of either the rotary assembly or stationary assembly is axially movable and usually spring mounted.  A rotor and stator component of the respective assemblies have sealing faces in close sliding proximity. One of either the rotor or stator is a composite ring comprising an interlocked pair of annular rings, an outermost of which constrains an innermost ring of dissimilar material.  A protruding seal face extends axially from this innermost ring or from the mating seal ring of dissimilar material.  Support rings for each of the rotor and stator are precisely matched with the corresponding seal ring to achieve precise control of the seal ring deformation.  An isolation ring may act as an adaptor to separate a support ring from any given mounting component.
