Title: Multiple channel video camera programming and control system
Inventor: SMITH WILLIAM V
IPC: H04N5/77
Filed: 1989-10-12
Abstract: ABSTRACT OF THE DISCLOSURE         An automatic multiple channel programming and video camera control system is disclosed in which, while the camera operator is operating the video camera system, the control signals generated by the operator are converted to a unique plurality of signals for recordation on a mass storage media, such a video tape recorder.          By the use of two or more dual tone multi-frequency circuits hav-ing different crystal oscillator frequencies in both the program-ming and decoder circuits, and causing the DTMF circuits in the programming circuit to provide their outputs as 1/20th of a second alternating pulses, multiple channels of control are generated for recordation on a mass storage medium, for example, a video tape recorder.  In that manner, two simultaneous camera control or other functions can be performed at the same time.  On playback of the mass storage medium, the recorded signals are reproduced, decoded and used to provide automatic control of the video camera system and auxiliary functions.  A modified video tape recorder may be used in which, during playback of the programmed signals, the video image is viewed by the selected video camera are recorded on the video track portion of the magnetic tape.

Title: Heavy duty fabric softening laundry detergent compositions
Inventor: CAO HOAI-CHAU
IPC: C11D3/26
Filed: 1989-10-30
Abstract: HEAVY DUTY FABRIC SOFTENING                LAUNDRY DETERGENT COMPOSITION          ABSTRACT OF THE DISCLOSURE:         A heavy duty fabric softening laundry detergent composi-tion, in liquid form, which has been found to be especially ef-fective in cleaning dirty laundry and in leaving washed laundry feeling softer to the touch, comprises certain proportions of a certain amphoteric detergent, such as is marketed under the trade name Ampholak 7TX, anionic surfactant of the higher alkyl ether sulfate type, nonionic surfactant of the polyethoxylated higher fatty alcohol type, inorganic builder and bentonite, in an aqueous medium.  Also within the invention are washing processes in which such laundry detergent compositions or components thereof are employed.  The liquid detergent described is of a pH in the range of 7 to 8 and of a viscosity in the range of 1,500 to 2,500 cps. at 25°C., and it is stable on storage.  The surfactants, bentonite, builder and enzyme (optional) are dissolved, emulsified or suspended therein, and the enzyme retains enzymatic activity even after normal storage.         Apparently due to synergism with the rest of the surfac-tant system, the amphoteric surfactant increases the cleaning activity of the liquid detergent composition on laundry to a greater extent than would have been expected, especially when the laundry is of fabrics made from cotton/polyester fiber blends, and the amphoteric surfactant, which is not a fabric softener, also synergistically increases the fabric softening activity of the bentonite.

Abstract: FAULT LOCATION OPERATING SYSTEM WITH LOOPBACK                Abstract of the Disclosure A fault-location operating system for use with transmission  networks  using  repeaters with  loopback capabilities.     A  plurality  of  bidirectional transmission links Li, for i = 1 through N, are used for transmission of data between the terminals.  A test control unit is connected at the first terminal to the first  end  of  the  first transmission  link  L1,  and controls  transmission of control  signals across the first transmission link L1.  A plurality of repeaters Ri, for i = 1 through N-1, are used for interconnecting the plurality of bidirectional links.  Each repeater Ri is connector to the first end of one transmission link Li and to the second end of another transmission link Li+1.    Each repeater  includes  a  first  circuit  for repeating data transmitted from the one transmission link L1 for transmission on the other transmission link Li+1,  and  a  second  circuit  for  repeating  data transmitted from the other transmission link Li+1 for transmission on the  one  transmission link Li.    In addition,  a  loopback  circuit  is  included  in  each repeater that is responsive to the control signals on the one  transmission link Li for looping back data transmitted  from  the  one  transmission  link  Li  for transmission back on the one transmission link Li.  In this system,  each repeater has a loopback capability responsive  to  control  signals  sent  through  the transmission links.   The  loopback capability can be provided in other elements in the network so that a single test control unit can be used to located faults anywhere within the network.

IPC: B65D33/20
Filed: 1990-03-19
Abstract: A flexible continuous reclosable plastic zipper having one strip with a groove and another strip with a rib for interlocking insertion therein, a hot melt plastic peel seal in the base of the groove with the rib bonded to the peel seal material to initially join the rib and groove and with the rib and groove breaking apart away from the bonding material at the first opening and thereafter releasably interlocking in a normal manner with the peel seal material remaining within the groove.  The groove is made sufficiently deep so that with initial interlocking, the rib must penetrate to the base of the groove deeper than normal operation to lock to the peel seal. When broken from the peel seal, the rib inserts sufficiently for the jaws of the groove to snap over the rib and then locks without interference from the peel seal which is relatively rigid and nonadhesive after the rib is first broken away.

IPC: B29C48/09
Filed: 1990-04-11
Abstract: Dual parison extrusion head (10) for multi-layer extrusion blow molding in which a die body surrounds two parallel spaced mandrels to form two cylindrical passages (12, 14) from which parisons are extruded. A series of resin supply conduits are provided for directing each resin to both passages. The series of conduits are axially spaced in the extrusion head to direct a plurality of plastic resins to each of the passages to form a multi-layer parison. The resin supply conduits (20, 22) are symmetrical about a vertical plane transversely bisecting the extrusion head between the two passages to produce flow and thermal symmetry in the resin to balance the resin flow to both passages. The resin supply conduits are configured so as to produce the dual parisons with the resin weld line of the multiple resin layers being located on the blow mold parting line. The resin conduits are positioned to minimize the center distance between parisons to reduce the size of the extrusion head. This is accomplished in part by feeding the resin downwardly before the resin flows into the cylindrical passages to form the parisons.
