Title: Turn signal monitor and override control for driver tuition vehicle - uses contacts in flasher to normal indicator switch circuit to indicate which side indicators are on and to reverse them if need be
Inventor: TORMOS RAYMOND
IPC: B62D1/22
Filed: 1981-06-19
Abstract: The signal lamp controller has indicator lamps (12g,12d) mimicking the vehicle turn signal lamps, enabling the instructor to check that the correct signal has been activated by the pupil. Two switches (9g,9d), corresponding one to the left lamp and one to the right, enable the instructor to cancel the incorrect signal and give the correct one. Each of these switches has a rest contact in the circuit linking the flasher unit to the normal flasher control switch (3), and a working contact in the circuit between the flasher unit and the instructors switch. Changeover contacts (15g,15d) allow the signals to be reversed with a single push button (10) action.

Title: Hydraulic locking device for vehicle brake - uses second piston in main actuating piston to lock main piston in activated position by friction coupling
Inventor: SCHNEIDER ROGER
IPC: B60T17/16
Filed: 1981-08-27
Abstract: A hydraulically actuated piston is displaced to operate the mechanism and a second piston can be displaced to lock or release the main piston. The second piston is tightly fitted inside the first, and the two pistons are locked by friction when the hydraulic pressure is released. To release the locking between the two pistons hydraulic fluid is injected between them. The main piston slides in a cylinder. An annular chamber is incorporated between the main piston and its cylinder wall, and dual hydraulic inlets are used, one for normal operation, the other for activating the locking piston. The annular sealing joints are provided between the contact surfaces of the two pistons. The volume between these two joints defines a chamber from which a fluid supply conduit is led out.

Title: Assembly installation using circulating pallets - uses coding system to control movement of pallets which are frictionally advanced by conveyor belt
IPC: B65G37/02
Filed: 1981-09-11
Abstract: The method of assembling mechanisms etc. in a workshop uses a system of manual work stations using benches constructed so that they can be assembled in a flexible manner. These are combined with a conveyor used to advance pallets between the stations so that components can be added to the mechanisms. The pallet is advanced by the belt along one edge, and is rectangular, designed so that it can be advanced by either long edge. The belt has strands at right-angles to each other and is driven by an electric motor. A pallet can be driven frictionally, and can carry a mechanical coding. It can carry a strip with a higher coefficient of friction than the remainder of its body. It can incorporate projections which are used to change its direction.

Title: Spacer and clamp for overhead power cables - has clamp articulated on spacer bar such that additional load imposed by rupture of cable causes lateral freeing of two parts
Inventor: MISCHLER JEAN-JACQUES
IPC: H02G7/12
Filed: 1981-12-21
Abstract: A cable clamp (20) having semi-cylindrical jaws (30) is connected to each end of a rectangular cross-section galvanised steel spacer member (10). The ends of the spacer are formed as a bar (16) of which the wider parallel faces (11,12) are rounded and tapers, and the narrower faces (13,14) are cut to form openings. The arm (23) of the clamp is articulated to the bar (16) by a bolt (40) passing through the sides (11,12) of the bar (16) and the arm (23), receiving an end washer (41) and a nut (42). When a cable breaks the resulting forces overcome the function between the clamp (20) and the spacer (10) articulation to provide a rotation, limited to 30 degrees by an abutment cooperating with a ribbed section. The end of the arm (23) is then free to detach from the bar (16) without contacting the spacer (10), thus relieving the additional load otherwise imposed.

Title: Fuel pellets or briquettes of high heating value mfd. from wood - by baking dry, grinding, opt. adding oil, and pressing
Inventor: SCHWOB YVAN
IPC: C10L5/44
Filed: 1982-04-20
Abstract: Materials rich in lignocellulose, e.g. wood, are converted to fuels by baking dry, pref. at 200-280 deg.C, grinding to powder, and agglomerating under pressure to regular granules. A binder, pref. mineral oil, can be added before agglomeration at a concn. of 1-5 (esp. 2-3) vol.%. To reduce the time required to bake dry, it is pref. to start with wood of small size, e.g. coppice wood roughly chopped up. Baking (torrefaction) can be in an inert atmos. for 0.5-5h, as described in French Application 81 16463. Final agglomeration may be by pelleting, granulation, briquetting, etc. The fuels can replace conventional solid fuels in all uses, including open fires and gas generators. The starting material can be large-sized and difficult as such to size-reduce. The fuel produced is homogeneous and of high specific gravity (0.6-0.7) and heating value (5,000-6,000 kcal./kg). It does not reabsorb moisture, and has low corrosivity on burning.

Title: Non-contacting workpiece gauging system - uses radiant energy beam projected such that illuminated spot moves along workpiece surface relative to reference
Inventor: WILDER JOSEPH
IPC: G01B11/02
Filed: 1982-05-11
Abstract: The system is for finding the position of a workpiece surface relative to a reference through non-contact gauging. The system uses a radiant energy beam projected such that an illuminated spot moves along the workpiece surface with movement of that surface relative to the reference along a measurement direction. An array- type image detector, which is out of physical contact with the workpiece, detects the illumination at each of a number of small areas of the workpiece surface and generates signals representative of the detected illumination. These signals are converted into a test signal which is a function of the difference in overall illumination between larger areas of the workpiece surface. A reference signal is produced and stored for two known positions of a workpiece surface. The test signal and the reference signal are combined with each other to produce a measurement signal indicative of the position of the workpiece surface relative to the reference.

Title: Electromagnetic separator
Inventor: SANDULYAK ALEXANDR VASILIEVICH
IPC: B03C1/033
Filed: 1983-02-28
Abstract: The separator comprises a series of chambers, filled with ferromagnetic packing, through which fluids can be circulated. The chambers are joined by a series of electromagnets, either equal in number to the chambers or a simple multiple thereof, to form a closed loop for the magnetic field. The ends of the electromagnet core pieces are constructed of material exhibiting magnetic hysteresis and are in close contact with the chambers so that the chamber packing remains magnetised after the power is switched off. Reversing polarity of the power supply is required to demagnetise the electromagnets to enable the chambers to be flushed of magnetic pollutants adhering the packing. Used for the removal of ferromagnetic particles from streams of liqs. or gases.
