Title: Stone block conveyor with crushing wheel - has tilting feed hopper, scraper chain conveyor and crusher with staggered arms
IPC: E21C47/10
Filed: 1975-01-10
Abstract: A conveyor for blocks of stone, suitable for use in a quarry which may be associated with a weighing or grading arrangement, has a scraper chain conveyor (16, 17) which slopes up at the feed end under a hopper which may be adjusted to tilt sideways. The conveyor then passes under a crushing wheel (3), with a set of side by side plates (23) with arms which are staggered. The chain wheels are driven by two hydraulic motors, each through a coupling, one each side of the conveyor. The crushing wheel is driven by a motor (21) and reduction gear (22) supported on bearings (25) so that the height of the wheel can be adjusted. Above the wheel is mounted a comb shaped plate (29) under the housing. A side by side multi conveyor arrangement may be used.

Title: Tyre deflation indicator including pressure sensor - actuates switch controlling radio emitter operating warning device
IPC: B60C23/04
Filed: 1975-04-30
Abstract: The tyre (29) deflation indicator is mounted on the wheel (30) with a switch which actuates a radio emitter. This acts on an alarm.

Title: Time switch circuit for infra-red heater - has short on-off cycle time by using RC time circuit to control triac
Inventor: LAFORIE PIERRE
IPC: H03K17/292
Filed: 1975-05-30
Abstract: The time switch circuit, for an infra-red heater, consists of a triac (Tr1) in series with the IR lamp and controlled from timing components that switch the lamp on for periods of 15 minuted. An FET controls the triac triggering circuit and is itself controlled by a variable RC timing circuit. The FET (Tr3) has its drain/source path shunted by a thyristor (Tr2) whose gate potential it controls. The triac gate is coupled via a diode (13) and resistor (R5) to the thyristor anode (FET drain). The advantage lied in reducing the on/off cycle time.

Patent FR-2284352-A1 (FR)
Title: Natural circulation continuous evaporator - heated partly by injecting open steam to siphon below the separator
Inventor: MATTERN KONRAD
IPC: B01D1/00
Filed: 1975-09-02
Abstract: Natural circulation continuous evaporation is done with improved heat transfer. The liquid is brought to boiling point before it enters the heating tubes by injecting open steam. This operation is performed at a higher hydrostatic pressure than at the tube inlet. Especially in vacuum evaporators for heat sensitive materials. Usually the heating of the liquid occurs in the lower part of the tubes where the liquid is moving slowly and heat transfer coefficients are correspondingly low. Boiling is inhibited by the hydrostatic pressure of the liquid in the tube. The method cited here performs most of the heating with open steam so that the tube heater can be much smaller than usual or can work at much higher capacity.
Patent FR-2285478-A1 (FR)
Title: Roving winding equipment - has paired parallel-mounted sleeves with tension and transfer control to wind new sleeves when wound packages are finished
IPC: B65H57/28
Filed: 1975-09-19
Abstract: An appts. for the winding of fibre materials into a package to make a roving out of silver, has a second bobbin sleeve so mounted that it is parallel to a first bobbin sleeve at the winding station. The material is wound on the first bobbin sleeve until it is fully wound when the material feed is transferred under the required tension and control to the second bobbin sleeve, the tension being exerted to no higher than that of the average fibre length. The system ensures that the material can be wound into packages of high density and of constant tension, without imposing breakages on the material.

Title: Femoral fracture reduction pin - has external grooves and screwed stem engaging in femur head
IPC: A61B17/74
Filed: 1976-03-04
Abstract: The pin is for the reductin of a sub-capital femoral fracture, having two arms fixed together.

Title: Telecontrol system for electricity distribution switching isolators - uses principal identification signal followed by auxiliary signal for state interrogation and switching control
Inventor: VOEUX RENE
IPC: G08C25/02
Filed: 1976-12-27
Abstract: The telecontrol system is of the type having at least a principal transmitter receiver unit and a series of transmitter receivers having receiving supervision. The principal transmitter receiver can transmit a principal identification signal followed by an auxiliary signal. It can also receive a secondary identification signal which is comparable to at least a part of the principal signal. A first actuating circuit is designed to actuate transmission of the principal signal followed by an auxiliary signal. The signals are used for state interrogation. A second actuating circuit actuates emission of the principal signal and auxiliary signals which form a telecontrol order. Each transmitter receiver is capable of receiving the principal and auxiliary signals and to transmit in return the secondary signal followed by state data. A first circuit reacts to the reception of the principal signal which corresponds to the specific valve of the secondary identification signal. The received signals being used to arm a control system and to trigger the control system.
