Patent FR-2284345-A1 (FR)
Title: Timing apptd. for use in casualty revival - provides visual or acoustic signals for cardiac massage or artificial respiration
IPC: G09B23/28
Filed: 1974-09-16
Abstract: The casualty revival apparatus incorporates acoustic and/or optical devices actuated by timing devices at adjustable frequency. The signals delivered by them allow one first-aid man or woman to carry out external cardiac massage or artificial respiration, or two to perform these operations simultaneously. The acoustic signals can be generated by an electronic oscillator circuit (2) connected to a frequency divider (3). The two signals of different frequency are fed to the timing devices, which are connected to amplifier circuits (10, 11). These supply the signals, cut off to suit the selected cycles, to loudspeakers. The apparatus can be set for infant, child, or adult.

Title: Dummy target launched from aircraft or airship - with set of ignited and combustible rings ejected in sequence
IPC: F42B4/26
Filed: 1974-12-11
Abstract: A dummy target to be launched from an airship or from an aircraft, to mislead a missile with an infra red tracking system by means of an ignition charge, has a set of combustible rings which are ignited, then discharged in succession so as to give a multiple number of ignition sources which makes tracking correspondingly difficult. A delay system is used to ensure that the combustible rings are not ignited immediately after the device has been launched, ejection being correspondingly delayed. The cylindrical casing houses the ignition and ejection systems and a pulse device which can be operated by remote control to actuate them.

Title: Folding push:chair for infant - has twin wheels on ends of front and rear bars joined by lateral struts
IPC: B62B7/08
Filed: 1975-07-28
Abstract: The folding child's push-chair has twin wheels (3, 4) mounted independently on the lower ends of two front (5) and rear (2) bars, jointed together by articulated lateral struts (9) so as to form the two sides of the chair. The seat is mounted between the sides, and there are rigid cross-members fixing the two front and rear bars together (6, 7). The bars pivot on an inverted-U-shaped handle (1), the rear ones at points part way along its arms.
