Abstract: ABSTRACT OF THE DISCLOSURE An exercising apparatus for full body exercise has a base member adapted to rest upon a floor and a support frame extending upwardly therefrom. The support frame has a pair of foot pedals pivotally attached thereto about midway of each foot pedal. A cross member attached to the upper end of the support frame has a pair of independently articulated pivotal arm handles rotatably attached to the cross-member. A pair of adjustable compressed spring tension devices are attached between each foot pedal and the upper cross member. A pair of actuating rods are pivotally attached respectively between each foot pedal and each arm handle, so that movement of either the arm handle or the foot pedal actuates the other member. Each of the two foot pedal - arm handle combinations is independently actuated, and not dependent on the other for movement. The foot pedals have pegs attached to the rearward ends to accommodate free weights; and the foot pedals have a solid member to tie the foot pedals together, as desired, to actuate both pedals together. 9947.1

Title: Network based outbound call management
Inventor: GAECHTER BARBARA I
IPC: H04M3/42
Filed: 1993-02-23
Abstract: An outbound call management capability is provided for a public switched telephone network by a network based outbound call management (NOCM) complex, which can be accessed by all subscribers to the public switched network through one or more central offices in the network. A predetermined list of telephone numbers is stored in a data base in the NOCM complex for each subscriber who uses the NOCM services. The telephone numbers are automatically dialed at one or more predetermined scheduled times. When one of the dialed telephones is answered, the NOCM complex sets up a connection through the public switched telephone network between the called party and one or more attendants at one or more telephone numbers specified by a customer of the NOCM services. The NOCM services are made available to any subscriber of the public switched telephone network by provision of a special access code which permits a subscriber who is a customer of this service to dial the NOCM complex which will then interact with the customer by responding to voice or DTMF commands from the customer. The customer may program the list of telephone numbers to be called and program the telephone phone numbers to be used by the NOCM system to connect awaiting attendants with parties automatically called by the NOCM system. The NOCM system customer may set the time for the execution of his calling program by theNOCM system, and may interrupt or otherwise influence or change the execution ofhis program. All of this may be accomplished without a need to purchase expensive outbound call management premises equipment or to retain the services of a special provider of outboard call management services.

Title: Process for controlling an injection molding machine
Inventor: HEHL KARL
IPC: B29C45/76
Filed: 1993-06-02
Abstract: Computer based interactive control of a plastics injection molding machine during input of portions of a production sequence and configuration of an injection cycle, which is effected essentially before the onset of the injection molding process. For a mold guided by an operator, operating parameters required for a process sequence are input by way of an input unit into a computer based control unit storing these operating parameters. Subsequently, one or a plurality of injection cycles are implemented according to the stored operating parameters. A physically possible production sequence, as well as a production sequence that is structurally specific to the machine and the tool employed, including any peripheral devices provided at the respective machine or associated therewith, is determined with the control unit. An operator is provided with a selection of possible inputs of further portions of the production sequence that can be added to the existing portions and are compatible with the machine and the tool based on the determination.
Patent CA-2098136-A1 (CA)
Inventor: YANKURA PETER J
IPC: H04W88/02
Filed: 1993-06-10
Abstract: A remote charging cradle is configured for charging a cordless telephone handset unit and also permits the handset unit to receive and respond to a radiofrequency ringing signal while located in this cradle. While being charged, the handset unit looks for a ringing signal over a direct-current charging path provided through its battery charge contacts. The operation which permits charging of thehandset unit while also permitting the handset unit to receive a radio frequencyringing signal is achieved through a power cycling arrangement which controls the period over which the charging current from the cradle is applied to the handset unit. By applying this charging current periodically and then only for relatively short periods of time, the handset unit is able to sense the radio frequency ringing signal generated by an associated base unit during those periods when the charging current is not being applied and thereby respond to the ringing signal.

The dispenser head (3) includes a dispensing duct (4) including two portions (11, 12) at an angle forming an  intersection  aperture  (13).  A  piston  (17)  is positioned to slide sealingly inside the first portion (11)  of  the dispensing  duct  so  that  it  closes  the intersection aperture (13) when at rest but opens it when the user squeezes the tubular body (1) forcing the paste into the first portion (11) of the dispensing duct. The piston  (17)  is connected by its rod  (18), through an aperture in the first portion  (11)  of the dispensing duct, to a resilient arm (8, 9) supporting a plate-like element (7) which covers the outlet orifice (6) through which the product is dispensed.  The movement of the piston  (17)  also  opens  the  outlet  orifice  (6)  and accumulates  elastic  energy  in the  arm  (8,  9)  which automatically returns the device to its closed position.

Abstract: In a digital radio-relay system having a transmitting terminal  station  (10),  at least  one  repeater  station (100),  and a receiving terminal station (50), a  repeater station (100) is a non-regenerative repeater station which does not regenerate a digital signal in order to  simplify and  reduce  cost of the system, while  keeping  excellent signal quality in transmission. Each repeater station  has a plurality of sub-units relating to respective sub-system signals  each having a plurality of carriers (A, B, C)  so that  frequency  spectrum  of each  sub-system  signal  is allocated on frequency axis based upon frequency  division multiplex  system. A repeater station (50) having a  first frequency  converter  (112)  to  convert  received   radio frequency  to  IF frequency, bandpass  filters  (132)  for deriving  one  of carriers (A, B, C) in  each  sub-system signal,  amplifiers (134) to amplify thus derived  carrier (A,  B,  C)  on  IF band stage,  and  a  second  frequency converter  (138)  to  convert the IF  frequency  to  radio frequency,  has a common reference oscillator (104)  which generates  reference  frequency which is common divisor of all the local frequencies for all the radio frequencies of all  the  sub-system  signals,  and,  only  one  of  upper heterodyne signals and lower heterodyne signals are  taken in  all the frequency conversions, so that  distortion  in each  relay  section is added in-phase,  and  that  leaked noise  (A',  B', C') caused by said  bandpass  filters  is added  to  original carrier (A, B, C)  in-phase.  All  the distortion  thus  added  in  the  relay  sections  can  be compensated. by  a  transversal  equalizer  (65)  in   the receiving  terminal station. Therefore,  excellent  signal quality  is  obtained although a  simple  non-regenerative repeater station is used.

Abstract: ABSTRACT OF THE DISCLOSURE                 METHOD OF MILLING       An improved method of milling a particulate material in a jet mill is described. The material is fed from a holding vessel to be entrained by a gas, the holding vessel having an ullage which is maintained at a pressure of at least 0.05 MPa but less than the pressure at which gas is introduced to the jet mill. The method is particularly usefully employed in an impact jet mill in which the entrained particles impinge upon a surface, are reflected into another jet and passed into a cylindrical separation chamber. The method enables such an impact mill to be operated under more energy-efficient conditions.
