Title: Fixing metallic decorations to plastic objects - by ultrasonically induced fusion of plastic substrates of decorations
IPC: B29C65/60
Filed: 1974-11-25
Abstract: The process is used for motor vehicles trim, i.e. metal rods on plastic substrates. The decorations are provided with anchoring-zones, which are submitted to the action of an ultrasonic generator, the sounding-line of which induces vibrations in the rods, at the level of their anchoring-zones on the substrates. This operation heats the latter sufficiently to cause local softening, making introduction possible by presing of the anchoring zones into the synthetic material. The method is easy, rapid and economical.

Abstract: A voice transcoder for use in compensating for sound distortions in helium speech, including a plurality of audio frequency channels, each defining a particular frequency band, the center frequencies of the channels being logarithmically spaced and frequency bands together covering the helium speech frequency band to be transcoded. Each channel comprises a band-pass filter coupled to a detector, a divider dividing band-pass filter by detector output to provide a signal having the frequency delivered from the band-pass filter at a standard amplitude, and a mutliplier multiplying divider output by another channel detector output to synthesize a part of the transcoded audio signal, the different parts of the transcoded signal being combined in an adder-subtracter. The said multiplier has one input coupled from divider output in the channel of rank i and the other input coupled from rectifier output in the channel of rank i + x, x being the same for any multiplier. x is selected in accordance with the proportion of helium in the gas breathed by the speaker. Each channel comprises a multiplexer selected according to x for performing the adequate connections to the channel multiplier.

Title: Solar energy collector with closely spaced parallel plates - and fluid flowing downwards between them
IPC: F24S10/50
Filed: 1975-12-10
Abstract: With downward flow, the press. can be kept low and the construction consequently lightened. The collector consists of a pair of parallel plates (the front one transparent) maintained at the required distance and with the connectors for the liq. flow; the plates may be placed vertically or obliquely; the spacing between them (pref. 0.05-1, better 0.1-0.5, mm) is maintained by wires along the line of greatest slope or by glass beads stuck to one of the plates; the transparent (glass) plate may be double. Energy is absorbed either with a blackened rear plate or by darkening the liq. with dissolved or suspended matter. The liq. is water or ethylene glycol (possibly stabilised with triethanolamine phosphate) or di- or tri-ethylene glycol or glycerol. It enters and leaves the collector at or below atmospheric press. The liq. temp. preferably remains within 10% of its value when the solar energy falls to 60% (alternatively 30%) of its max.

Patent FR-2337274-A1 (FR)
Title: Snap action rod end to end assembly - has tongues formed by transverse slot of one rod fitting into recesses of mating rod
IPC: F16B7/04
Filed: 1975-12-30
Abstract: In order to join two rods end to end a transverse slot is cut in the end of each rod to form two prongs (11, 111) with pointed ends (112). Concave surfaces (12, 121) are formed opposite to one another and extend inwards from the base (122) of the transverse slot. The contours of the prongs (11, 111) are such that they fit with a snap action into the slot formed between the prongs of the mating rod. This produces a rigid joint which can only be separated by a load acting along the axis of the rods. The security of the joint can be further increased by fitting a spring loaded sleeve which must be slid to one side before the joint can be separated.

Title: Flat embroidery adjustment mechanism - has a simultaneous and synchronised infinitely variable setting for needles and shuttles
IPC: D05C3/04
Filed: 1976-03-08
Abstract: An embroidery machine, esp. a flat embroidery machine, has an adjustment for the positioning of the needles on one side of the fabric and the shuttle on the other side, simultaneously and synchronously, individually or in groups or over the total embroidery operation. The design eliminates the time taken for individual adjustment of the embroidery components, as the needles must enter the shuttles accurately, increasing the range of patterns which can be executed, simplifying the pattern control system, and increasing the operating speed and productivity.
Patent FR-2345199-A1 (FR)
Title: Differential press. indicator - to register fouling,esp. of oil filters in engines
IPC: B01D35/143
Filed: 1976-03-23
Abstract: A differential press. indicator shows only that press. drop which is due to fouling across a component, such as a filter, in a fluid system. The indicator employs a piston having two surfaces. The press. upstream of the component acts on the first surface and the press. downstream acts on the second surface. The forces on the piston due to the two pressures, acts in opposite directions. A differential arrangement provides the second surface with a mechanical advantage over the first, whose magnitude is such that the force resulting from the downstream press. (i.e. the lower press.) is greater than that resulting from the upstream press. under normal conditions when the filter is clear. The press. drop required to overcome the mechanical advantage is the predetermined max. allowable press. drop through the filter due to fouling. When this press. loss is reached, the piston responds and an indication is given by a visual device. Used esp. for oil filters in I.C. engines. Reliable indication of the true degree of fouling maximises filter utilisation and reduces wastage and pollution due to oil spillage when filters are replaced. The indicator operates accurately regardless of varying engine speeds and other variables influencing the press. in the system.

Title: Programmed slide projection time system - uses coded strip attached to slide magazine read by light detection system
IPC: G03B23/00
Filed: 1976-06-28
Abstract: The programmed slide projection system uses a coded data support (2). This support (2) is fixed to the slide magazine (1). The slide magazine may be circular or rectilinear. The support (2) may also be fixed to film strip. At each slide position the data support receives a code. This code permits control of the slide projector. A reading head is placed on the projector opposite coding positions which are displaced when the slide magazine is moved through the projector by the transport mechanism. The coding support can be incorporated on the magazine during manufacture. For existing magazines the support can be glued to the magazine. In the case of a disc magazine or film strip the coding can be printed or on photographically applied.

Title: Two stage turbine driven by blast furnace exhaust gases - has valve to bypass second stage at low gas pressure
Inventor: INUBUSHI MASANOBU
IPC: F01K25/14
Filed: 1976-07-06
Abstract: The blast furnace (3) is supplied with air from the fan (1) and heater (2). The exhaust gases from the blast furnace (3) then pass through a cooler (4) and dust extractor (5). The gases then pass through a system of control valves (7, 8, 9, 10) to the two-stage turbine (11) which drives the generator (14). When the pressure of the gases is high, they pass through both stages (11a, 11b) of the turbine. When the pressure is low, a valve in the low pressure line is closed and the gases flow directly through the bypass (24) to the outlet. The bypass valve enables the turbine to work at maximum efficiency over a wide pressure range.

The stop (6) is lowered to permit transfer of a support to a trolley for removal to the next assembly station.
Patent FR-2345323-A1 (FR)
Title: Test circuit for anti skid brakes - has flip flop circuit to operate test every time ignition switched on when speed reaches set level
IPC: B60T8/88
Filed: 1977-03-24
Abstract: The anti-skid brakes are fitted with an automatic test circuit which tests the whole system every time the ignition is switched on and which provides a warning signal if the response signals are not correct. The tests are performed when the wheel speed reaches a set level, so that transient signals associated with starting, are eliminated, and with the set speed low enough not to warrant anit-skid braking control. In order to prevent the test sequence being performed every time the speed drops to the set value, a simple flip flop circuit is primed when the ignition is switched on and switches to the test sequence when the speed subsequently reaches the set level.
