Title: Safety device for moving press platen - retains platen through rack and pinion drive controlled by clutch
IPC: F16P3/00
Filed: 1974-09-24
Abstract: The moving platen (1) of the press is operated by the piston (2). To prevent unintended downward motion which could be dangerous to the operator, a rack (10) is attached to the platen (1) and meshes with a pinion (9). The pinion (9) is mounted on the shaft (7) which runs in bearings (4), (5) and (6) and carries the clutch (11), (12) and the free wheel (13) and (14). The clutch members (11) and (12) are normally engaged and the free wheel (13) (14) permits only upward movement of the press platen (1). The clutch is only disengaged when the press is switched to descend and the clutch automatically re-engages in the event of any failure in the press control system.

Title: Gaseous bubble injection device in liq. - for flotation of suspended and colloidal matter
Inventor: STERLINI JACQUES
IPC: B01F3/04
Filed: 1976-02-27
Abstract: Gaseous bubbles are introduced by an injection device into a liq. in a recipient for the floatation of pulverulent or colloidal matter in suspension in water. Water is introduced into the emulsifier by the pump through a vertical tube. Air is admitted through the tube, with a peripheral emulsifier with a deflector immediately below its lower end. The emulsifier assembly is immersed in the water to be treated in the tank. The air emulsified in the water is deflected in the horizontal direction across the base of the tank, as shown by the arrows, the speed decreasing gradually under the effect of friction. Device is simple and uses but little energy. It supplies the flotation bath with a system of bubbles with a dia. 100 mu without causing eddies that would destoy the particle floccules or unstable agglomerates.

Title: Split-phase signal demodulator - includes null detector having pulse output applied to sampling circuit
IPC: G11B5/027
Filed: 1976-04-09
Abstract: A method for the demodulation of split-phase signals recorded in sequence on a magnetic tape, applicable to the processing of recording of instrumental readings or of digital information using split phase mark or split phase change techniques. The information content is derived with improved signal to noise ratio and the method is easily adaptable to a different bit rate without necessitating any change in the phase of the reproduced signal. Demodulation is effected by sampling the reproduced signal using a bit rate of suitable phase setting, the information content being recovered through a logic coupling of pairs of successively sampled symbol values, the bit rate being derived by sampling of a sawtooth signal at the zero transits of the reproduced signal to obtain a control voltage which controls a voltage-controlled oscillator through a filter. The oscillator is thus brought into appredetermined phase in relation to the recorded binary pulse series.

Title: Sepn. of particles, droplets etc. from air - esp. cooling air for electric locomotives operating in snow conditions
IPC: B01D45/16
Filed: 1976-10-29
Abstract: In the separator, the air flows around a curved passage and the particles, droplets, etc. contained in it are sepd. by the resultant centrifugal force. Separate passages are connected to the sepn. duct for removal of the cleaned air and the sepd. particles. According to the novelty, the particle-removal passage is connected to a jet-ejector which is driven by a jet of air which is part of the stream of cleaned air. The driving air stream is returned to the ejector by a pipe connected to the duct for cleaned air. Efficiency of sepn. is higher, since the sepd. particles are removed continuously. Removal of the particles is also easier since they are not allowed to build up into an intermittently scraped layer.

Title: Mixer for viscous fluids - comprising tube with tangential nozzles inducing alternating rotational flow pattern
IPC: B01F33/40
Filed: 1977-01-10
Abstract: Equipment for mixing viscous fluids comprises a tube with side nozzles A, B, and C. The side nozzles arrive at the inner tube surface almost tangentially, pointing downstream by about 10 degrees. Nozzles B are radial in direction, but point slightly downstream. The fluids moving down the tube are split into substream by nozzles B, and rotates by nozzle A, C. To improve mixing nozzles A, C point in opposite directions. The fluid inserted through the nozzles may be one of the components, or may be a gas such as air. The mixer is partic. suitable for preparation of foamable resin compositions, esp. those containing reinforcing fibres. For such materials, mixing must be rapid prior to moulding. Prior mixers have incorporated baffles leading to dead spots and difficulty in cleaning.
