Patent FR-2309494-A1 (FR)
Title: Safety detonator for rock excavations - has small charge in short thick tube inside long thin tube
IPC: F42B3/195
Filed: 1975-04-29
Abstract: A safety detonator comprises a detonating element (b), consisting of a very small quantity of explosive, situated in the bore of a thick-walled tube. This tube in turn is inserted in a long, open-ended, thin-walled tube (a), one end of which is connected to the detonator cord and the other to the fuse or electrical detonator (c). The thick-walled tube is pref. of metal, a metal alloy or a structurally strong plastic material compatible with the explosive mixture. It is pref. an integral part of the thin-walled tube or alternatively may be pressed, bonded or passed into the thin-walled tube. The total weight of explosive mixture is 4-200 (20-80) mg. The length of the thick-walled tube is at least 1.5 times its internal diameter. There may be a delay device, either inside the thick walled tube itself or outside it. Used in particular for mining, quarrying and tunnelling. The detonator is virtually proof against accidental detonation as a result of shock. It is therefore extremely safe to transport and handle.

Title: Roller blind with upper blind box - has spring stop on lowest blind slat engaging fixed stops on box
IPC: E06B9/82
Filed: 1976-01-09
Abstract: The blind has horizontal inter-articulating slats (5) and stops limiting retraction into the usual overhead box (2). Stops (16) on the box are engaged by elastic stops (12) on the ends of the lowest blind slat (6) and in the lateral blind guides (7). The stops (12) are within the contours of the slat (6), and yield elastically upon encountering the stops (16). Each stop (12) is typically in the form of a spring strip or a spring wire member secured in the end of the slat (6), and yields downwards when it engages a fixed stop to provide damping.
Patent FR-2338440-A1 (FR)
Title: One shot valve for pneumatic circuits - has varying cross-section shaft sliding to connect pulse receiver to relief port
IPC: F15C3/16
Filed: 1976-01-13
Abstract: This pneumatic valve allows the transmission of a compressed air pulse to a receiver and automatically shuts off only when upstream and downstream pressures are equalised. Subsequently, the receiver is automatically discharged. To supply another pulse, the actuator button must first be released and then used again. The action is achieved by combining three elements in the valve body. These comprise the actuator button and spring loaded valve, a varying cross section sliding shaft and a spring loaded non-return valve. Air is admitted via an inlet port and delivered after activation of the button to the receiver via a discharge port. When inlet and receiver pressures equalise, the shaft slides along and connects the receiver to a relief port.

Title: Hydraulic ram with coaxial cylinders - has central telescopic flow tubes and apertures through cylinders
IPC: F15B15/16
Filed: 1976-03-23
Abstract: Each hydraulic cylinder, with the exclusion of the first which is largest in diameter, constitutes the piston of the preceding cylinder and the hydraulic cylinder of the following piston. All cylinders are divided into two compartments, connection being through radial apertures, except for the first cylinder. A telescopic tube coaxially fitted inside the assembly of cylinders communicates with the innermost cylinder. Connecting passages and apertures act alternatively for admission or discharge of the hydraulic fluid as the assembly extends or retracts.

Patent FR-2324090-A1 (FR)
IPC: G11B3/20
Filed: 1976-09-14
Abstract: For reproducing signals recorded on an image recording disc in a spiral groove, there is a pick-up pin (15) at the end of a supporting arm (19), the mass of which is less than that required for the desired track-keeping force. The track-keeping force is generated by a leaf spring (33), tensioned between the pick-up pin (15) and a rest (14) of the reproducing apparatus. This has the effect that the pick-up pin returns quickly to the disc groove when it has been thrown out from the said groove by an undesired force on it. The spring also has the effect that the free end of the pick-up arm, held in a compliant part (21) of the apparatus, is always held in the correct position in relation to the rest, and can furthermore serve the purpose of establishing an electrical connection with a signal-processing circuit of the disc player.

Title: Shed formation on a hand loom - uses a system of cables and pulleys, controlled by pedals
IPC: D03D29/00
Filed: 1977-02-24
Abstract: On a hand loom, the formation of a shed is effected with pedals by lifting the shafts using a system of cables and pulleys. This replaces a known system of rocker bars attached to pedal levers by cords. The cable and pulley system provides great regularity in the lifting of the shafts. It promotes a strong vertical parallel movement of the shafts, without risk of jamming. The arrangement of the shafts can be changed quickly.

Patent FR-2357130-A1 (FR)
Title: Video tape recorder and playback - has chrominance components combined with reference signals whose phases continuously advanced and lagged and recorded
IPC: G11B20/02
Filed: 1977-06-29
Abstract: The recorder uses several tracks on a medium for recording the composite colour t.v. signal with characteristic chrominance components in repeated line and frame sequence. The recorder has a sequence signal generator (20) for generation of a first reference signal whose phase continuously springs forward at a rate corresponding to the line sequence. It generates also a second reference signal whose phase continuously springs back at the same rate. A combination circuit (7) combines the chrominance components alternately with the first and second reference signal. The combined signal is then recorded (11) on the recording medium.

Title: Bactericidal liq. spray to disinfect interior of buildings - with liq. droplets pumped into atmos. or air conditioning duct
IPC: F24F8/24
Filed: 1978-01-13
Abstract: The equipment comprises a power driven hydraulic pump drawing liq. from a container. The pump delivers liq. via a pipe terminating with a directional nozzle discharging tiny droplets of liq. into the atmos. The nozzle can be free for manipulation by an operator or fixed to delivery always in the same position. A fixed nozzle can be installed inside air conditioning ducting to deliver downstream into air current. When located to delivery into an air conditioning duct or open atmos., the pump is pref. operated intermittently by a programmed timer. For manual use, the nozzle can be fitted at the end of a pipe lance so that walls and ceilings can be directly sprayed. The spray is liq. droplets rather than an air/liq. emulsion. Consequently, a compact unit can delivery liq. at a faster rate than previous equipment.
