Title: Exercise device
Inventor: HANER LAMBERT
IPC: A63B23/04
Filed: 1991-03-27
Abstract: ABSTRACT      An exercise system including an exercise device having a user actuatable pedal mechanism coupled to a permanent magnet, DC motor operated as a generator and a load control arrangement for controlling a braking effect exerted by the DC motor on the pedal mechanism. The output of the DC motor is connected to a power dissipation circuit including plurality of power MOSFETs. The system can he operated in a constant power or a constant force mode.  In the constant power mode, the load control monitors the output of the DC generator and compares it with a selected power level and in response to detected errors between the signals, adjusts the conductivity of the power MOSFETs to maintain the power output independent of actuation speed.  Current flow through the power MOSFETs is monitored and the relative conductivity between the MOSFETs is adjusted in order to maintain substantially equal current flows through each MOSFET.  Power for the electronics is obtained from the DC generator using a two-stage power regulation circuit in which the second stage includes positive and negative regulators and the first stage includes a means for limiting the input voltage to the regulators to a predetermined maximum.

IPC: F02C7/08
Filed: 1991-05-16
Abstract: ABSTRACT OF THE DISCLOSURE The gas turbine installation has a gas turbine with two stages (HD, MD) of different pressures and an energy exchanger (ET) connected as upper stage of the gas turbine. High-pressure air compressed in the energy exchanger (ET) is fed to a burner (NB) acting on the energy exchanger (ET) and to a combustion chamber (BK) of the gas turbine. Propellant gases discharged by the energy exchanger (ET) and a high-pressure stage (HD) of the gas turbine are fed to a low pressure stage (MD) of the gas turbine. The gas turbine arrangement is intended to be distinguished by  simple construction and high effi-ciency and to be advantageously influence in its mode of operation in respect,  for instance, of rapid load changes.         This is achieved by the following measures: -    a heating element (e.g. H2) is provided in a leg (e.g. HD2) carrying high-pressure compressed air, -    a  cooling  element  (e.g.  K1)  is  provided  in  a propellant gas-carrying leg  (e.g. MD1)  branching off from the energy exchanger (ET), -    heating (e.g. H2)  and cooling element  (e.g. K1) are interconnected as a heat exchanger (e.g. W12) for the purpose of recuperation or regeneration of heat.

Title: Apparatus for filling large packs with foil bags
Inventor: FOCKE HEINZ
IPC: B65B5/10
Filed: 1991-06-19
Abstract: A b s t r a c t : (referring to Fig. 3) When  cartons  are  filled  with  foil  bags containing bulk goods susceptible to mechanical stress, a  high  performance as  well  as  a careful treatment of the foil bags has to be ensured. The foil bags (10) are fed to a  packaging  station (13)  and  are deposited on top of one another on a platform (36) of an elevator (26) which lowers  the  foil  bags  (10) into  the carton (11) which is open at the top. The elevator (26) enters the carton (11),  which  is  also  open at  the bottom,  from  below. The carton contents are lowered to the plane of a carton bottom. When  the  carton  is  discharged, folding  flaps  are  folded over to form a carton bottom. To increase performance, upstream of the  elevator (26)  there is  arranged  an intermediate conveyor (20) which is already being loaded with the foil  bags  (10)  while  the  elevator (26)  is  still  located in  a  lower  position and another carton (11) is supplied. This ensures an  almost  continuous feed and transfer of the foil bags (10).

Patent CA-2061366-A1 (CA)
Title: Compression of signals for perceptual quality
Inventor: JAYANT NUGGEHALLY S
IPC: H04B14/04
Filed: 1992-02-17
Abstract: Compression of signals is achieved through a simple decision of whether or not to encode certain frequency bands; not how well to encode all of the frequency bands. Based on the input signal and on a preselected perceptual model, a "just noticeable difference" (jnd) noise spectrum is computed. This spectrum is applied to a selector where it is used in the decision to select a chosen number of frequency bands of the input signal. The bands selected are the bands with the greatest energy relative to the jnd energy in the same band. Each of the selected bands is encoded and transmitted to the receiver. Both analog and digital realizations are presented.

Abstract: SHAPING AND TRIAL REDUCTION GUIDE FOR IMPLANTATION OF      FEMORAL PROSTHESIS AND METHOD OF USING SAME                             ABSTRACT     According to the invention, there is provided a trial implant comprising a modular bracket defining a structure having an internal surface adapted to be seated on the distal aspect of a resected femur bone and an external surface with a shape resembling the normal distal condyle of the femur.  The bracket has an elongated central opening appointed to expose the resected bone of the femur, including a pair of tracks for guiding a tool along a predetermined path for controlled shaping of a patellar groove in the bone exposed through the opening.  A replacable insert covers the opening and articulates with a proximal aspect of the tibia during interoperative trial reduction of the knee joint, whereby prior removal of the bracket from the resected bone is unnecessary following shaping of the patellar groove. Preferably, the insert and guide tracks cooperate together to securely position the insert within the opening during trial reduction.  A surgical method is also provided using the described trial implant guide.

Title: Communication system applicable namely to air traffic control
Inventor: BERRY GEORGES
IPC: H04J3/17
Filed: 1992-04-02
Abstract: The invention relates to a digital communication system for a network operating in half-duplex mode and comprising a bus for speech and a bus for service messages. Since the latter are of considerable volume, it is advantageous to unburden the bus transporting the marshalling messages by sending a part of these messages via the speech bus and to thus ensure real-time transmission of the information. In order to be able to distinguish the two types of information on reception, the invention provides for the placing, at the level of each service message transmitted in place of a silence, of a recognition sign consisting of a code individual to the speech encoding law, and which is unobtrusive since it is unused or redundant as regards the transmission of speech. The invention provides preferentially for the use of the encoding law A which possesses not merely a redundancy, but what is more, a redundancy in the encoding of silences. The invention applies in particular to air traffic control. <IMAGE>

Abstract: ABSTRACT OF THE DISCLOSURE          The specification discloses a device for tilting a truck box cover to  an angular position thus providing improved access to the cargo area.  The  box cover is mounted to the side of the truck box by a hinge.  The box cover is assisted in lifting to an open position and held open by an  actuator which may be a single gas spring or a screw powered by an electric  motor.  The actuator is positioned near the front of the truck box so it  causes minimum obstruction of the cargo space.  The device may be used with  conventional truck box covers.  The box cover can be stabilized in a non- closed position by a steady strut.  A restraint prevents over-opening of  the box cover.  A strong frame prevents excessive deflections of the box  cover and enables the use of one actuator.
