Title: Connecting device for two mobile carriages guided on parallel rails
Inventor: ETCHEPARRE JEAN
IPC: B23Q1/26
Filed: 1980-09-25
Granted: 1984-03-01
Abstract: An apparatus is provided for the interconnection of two mobile carriages which are connected by a rigid beam and guided along parallel guide rails. The apparatus permits the simultaneous and identical movement, with respect to both direction and distance, of the carriages along the respective guide rails. The apparatus comprises two generally symmetrically disposed cables, each of which is attached at one end to an end of one rail and at its other end to a diagonally opposed end of a parallel rail. Intermediate the attachment points, the cables connect the carriages by resting on and being supported by return pulleys which are integral with the carriages. Each cable thereby describes a generally Z-shaped configuration. The Z-shaped configurations are symmetrically disposed in order to cause, during the displacement of one carriage, the tensioning of one of the cables, and thereby cause the other carriage to be identically and simultaneously displaced.

Title: Device for locking two members
Inventor: HOISETH JOHN WILLY
IPC: F16B7/04
Filed: 1983-04-21
Granted: 1987-08-13
Abstract: The invention relates to a device for locking together two members which are telescopically movable in relation to each other with a given clearance between the two members, when the device is in the neutral position, for example a rod or a tube inside an outer tube or a rod or a tube inside an outer sleeve. According to the invention there is an annular recess in the area of the inside of the outer member. In this recess (7) there is fitted a sleeve (8) the external dimensions of which are smaller than the external dimensions of the recess so that the sleeve can be displaced in radial direction in the recess. The clearance (D1) between the sleeve and the inside of the outer member in the area of the recess is greater than the clearance (D2) between the sleeve and the inner member. The inner member (2) extends through the sleeve (8). A screw (11) or something equivalent is provided for the purpose of displacing the sleeve in radial direction in the recess, in the process of locking, and forcing the sleeve against the inner member in such a manner that the latter is locked between on one side the inside of the sleeve in the area of the application of force and on the other side the inside of the outer member on both sides (4,5) of the recess.

Granted: 1990-03-15
Abstract: The vehicle engine drives through a gearbox half-shafts (66) and final drive reduction units (68). In order to reduce manufacturing costs without introducing excessive wear, the gearboxes of a range of vehicles (covering say a 2:1 power range) are alike. The increased power up the range is transmitted by driving the gearbox faster via an equalizing gear (16) which may be separated or an input stage of the gearbox (90) itself. The torques at the output (12) of the equalizing gears are the same throughout the range. The final drive reduction (68) have different ratios such as to establish the correct wheel speed throughout the range, taking into account also different wheel dimensions. The final drive reduction units (68) are two stage planetary units capable of high reductions needed at the top of the power range. The two stages (94, 96) have rotationally fast planet wheels (100, 102) in a common carrier (104) which also forms the wheel hub. The first stage (94) has only an input wheel, namely a sun wheel (98) which is fixed to the half shaft (66) while the second stage (96) has only a fixed wheel which is a sun wheel (106) in the case of lower power vehicles. The fixed sun wheel is replaced by a fixed annulus in the case of a higher power vehicle.

Title: Dimensonally stable thermoplastic tubular articles
Inventor: BUTCHER PETER EDWIN
IPC: B29C71/02
Filed: 1984-04-04
Granted: 1987-07-09
Abstract: For heat-setting tubular articles (such as can bodies) of an at least partly biaxially oriented crystallisable polymer, preferably a saturated linear polyester such as polyethylene terephthalate, e.g. for thermally processable food containers, a tube (26) of the polymer is fitted over a mandrel (101) and clamped at its ends to the mandrel at a temperature belowthe glass transition temperature of the polymer. The tube is then heated, e.g. by inserting a heater (28) into the interior of the mandrel, above the temperature to which it is to be heat-set (at least 60°C above for PET) whereupon it shrinks into contact with the mandrel but is restrained from axial or further radial shrinkage. The tube and mandrel are cooled to below the heat-set temperature and the tube may then be cut by knives engaging in circumferential grooves (22) into can body sections. Contact between the tube and mandrel is released, e.g. forforcing compressed air out through small holes (16) in the mandrel surface to allow the tube and mandrel to be separated.Tubularbodies with one closed end can be heat-set on a mandrel with a correspondingly shaped end.

Patent DE-3468960-D1 (DE)
IPC: H02M5/45
Filed: 1984-08-28
Granted: 1988-02-25
Abstract: The invention relates to a parallel resonant-circuit converter having at least one intermediate-circuit inductance. In order to guarantee that the inverter will start even with different loads, the voltage produced when discharging a separately charged capacitor across the load is monitored. At some time after the maximum voltage across the load is reached, another separately charged capacitor is discharged via a thyristor of the inverter located in the biasing circuit of the intermediate-circuit inductance. Because of the blocked thyristor and of the capacitor charged to the voltage maximum, the biasing current is forced to flow via diagonal branches and including the load. In this manner, reliable starting of the inverter is possible even with loads having a different natural frequency.

Title: Measuring system for the fuel-air mixture of a combustion engine
Inventor: BLOCHER EBERHARD DIPL ING
IPC: F02D41/34
Filed: 1984-12-18
Granted: 1988-12-08
Abstract: The invention is directed to an apparatus for metering an air-fuel mixture to an internal combustion engine. The apparatus includes a characteristic field set up with operating quantities of the internal combustion engine for anticipatorily controlling engine variables that influence the air-fuel mixture and a control arrangement, responsive to at least one engine variable, for correctively influencing the characteristic field values. The characteristic field values are stored in the characteristic field and selected in dependence on operating quantities of the internal combustion engine. The characteristic field values are modified by means of different control methods to correctively influence the same. More specifically, the control methods include a control to a minimal specific fuel consumption in the lower and part-load ranges as well as a control to maximum power in the upper load range as may be necessary. This control arrangement can be realized, on the one hand, with an extreme-value control which is superposed either on the air or quantity of fuel delivered to the motor or, on the other hand, with a direct control of the air ratio  lambda  with an exhaust gas probe, for example. With the apparatus of the invention, a minimal specific fuel consumption with reduced exhaust gas emissions are realized while at the same time ensuring a satisfying driving behavior of the vehicle.
