Title: Frozen food reheating oven - heats by radiation and circulating hot air, with air passing over heating elements
Inventor: TRICAULT GERARD
IPC: A47J39/00
Filed: 1975-06-26
Abstract: The mobile oven is for the quick re-heating of frozen pre-prepared food dishes. The dishes are heated by a combination of direct radiation from electric elements (11, 12), and circulating hot air. The circulating air is heated by the same electric elements which heat by radiation and, thus has a cooling effect on the electric elements, giving a greater energy output. The oven may be of hollow box form with heat retentive walls (5) and door (6). Inner walls in the form of plate heating elements (11, 12) and an occlusive screen (8) may form a cavity with the outer walls (5), for circulating air (F1, F2) which thus passes over the rear faces of the elements (11, 12). A fan (4) at the rear forces air to circulate past the elements and to return over the food area. Separate elements (7) may boost the air temperature.

The vibratory excitation may be applied by the fall of a ball in a tube (14) or the application of vibrations to a specific point of the component. A microphone (1) and bandpass filter are used to detect the emitted sound.

Title: Digital voltage measuring circuit - with voltage to be measured compared with a reference voltage in several steps
IPC: H03M1/00
Filed: 1975-11-20
Abstract: The steps of the digital voltmeter are made smaller and smaller by switching a voltage divider, so that the two voltages are made equal. Switching commands are derived from the comparator, and depend on the existing amplitude difference. The divider position reached at voltage equality is evaluated. Division ratio is switched in individual stages (A-D) as required to greater or smaller values depending on the polarity of existing amplitude differences (Ua-Ur). The voltage to be measured (Ux), possibly after division, is applied to an integrator (5) whose integration time can be switched in order to derive switching commands (B1-B4) for individual stage (A-D), so that integration time increases with decreasing value of the stage.

Patent FR-2305880-A1 (FR)
IPC: H02K23/24
Filed: 1976-03-26
Abstract: The DC machine contains auxiliary poles which each have an excitation winding and a forcing winding in order to compensate for a magnetic flux which is produced in the commutation zone by eddy currents in the magnetic conductor of the auxiliary poles. The forcing winding (11) is connected in parallel with, and in the same sense as the excitation winding (10) of the auxiliary poles (9) and its resistance is at least twice as great as the resistance of the excitation winding (10) of the auxiliary poles (9). The forcing winding can be located closer to the commutation zone (14) than the excitation winding of the auxiliary poles (9), its number of turns being equal to or greater than, and its inductance less than, those of the excitation winding. The forcing winding (11') can, however, also be located further away from the commutation zone (14) than the excitation winding (10'), its number of turns then being equal to or less than, and its inductance greater than, those of the excitation winding (10'). The DC machine furthermore contains a means (20) for reducing the stray flux ( PHI S) of the auxiliary poles (9). This means has the form of plates (20) which consist of ferromagnetic material and are mounted in the non-magnetic gaps between the cores of the main poles (6) and the auxiliary poles (9) in the arrangement zone of the winding (10' or 11') which is furthest away from the commutation zone (14). However, this means can also have the form of a bead on the auxiliary pole (9).

Title: Anisotropic sheet mfr. from resin bound and compressed grains - to obtain low density, resilient or insulating paper or board
Inventor: ARGUILLERE JEAN
IPC: C04B26/02
Filed: 1976-04-09
Abstract: Sheet materials out from tubular stock are made by lay-up of a mixt. of fibrous granules and a binder resin with partial flattening of the granules by axial or radial compression prior to hardening the binder. The mixt. of resin and granules may be laid up in successive layers either within a cylindrical mould, suitable for applying axial compression, or round a mandrel, suitable for applying radial compression. Suitable for mfr. of thick or thin sheet, esp. alternatives to asbestos paper as an acoustic barrier beneath floor tiles or where a high specific stiffness (stiffness/wt. ratio) is required. Natural granules maintain multiaxial fibre orientation internally and an intrinsic flexibility and elasticity better than sheets fabricated from individual chopped fibres. Uniform distribution of low binder resin conons, is more readily attained. The direction and degree of anisotropic stiffness is more readily reproduced and controlled by the direction and degree of compression of the original granules.
