Title: Capillary net for covering bald head - with large mesh for passage of hairs and hooking means
IPC: A41G3/00
Filed: 1975-10-22
Abstract: Capillary net for covering bald head comprises a net with a large mesh for passage of hairs, and hooking means coacting with the net for application and fixing of the net to the head of the wearer. The hooking means pref. consist of clip which grip the hairs extending through the holes in the net. The net is pref. pre-cut to a shape which conforms as closely as possible to the wearer's bald patch. It can be removed by detaching the clips which fix a lock of hair in the hole in the net.

Title: Telephone answering and recording circuit - responds to call only if bell rings for given time defined by blank length of tape
IPC: H04M1/64
Filed: 1976-02-16
Abstract: Circuit providing an automatic recording of incoming calls to an unattended telephone. The circuit only responds to persistent ringing of the telephone bell. The mechanism is based on the use of a magnetic recording tape loop having a short blank section (12) the remainder of the tape being occupied by these tracks. One track provides an acknowledgement of the call (19). The second (13) transmits a tone closing the handset switch only if the bell which initiates the tape movement rings long enough for the blank tape section to pass a tape head. The third track (22) carries a further tone coupling in a tape recorder to take the callers message.

Title: Differential swept multi-path auto-collimator - is used for determination of angular movement of system mirrors and consists of cylindrical drum
IPC: G02B27/30
Filed: 1977-03-16
Abstract: Digital differential autocollimator sweeping through two or more axes sequentially and used esp. for the determination of the orientation of mirrors etc. and their varation in position with respect to time. The collimator is based on the use of a cylindrical drum rotating at a constant speed with a light source off-centred within it. Light is transmitted via a semi-transparent filter from the drum through a continuous zig-zag slot in the drum walls, the angle between the slots being 90 deg.. Beam splitting is via a dichroic element between an objective and the target mirror, a secondary mirror reflecting the diverted half of the beam towards the second target mirror.

The pin is at a constant distance from the external edge of the cup, just above the girdle of the stone (7). The mounting can be used for a series of stones when the pin joins the claw of the stone to that of the next stone.
Patent FR-2346151-A1 (FR)
Title: Rotary printing machine with blanket clamp - has cylinder surface near clamping channel flattened to receive bead of rubber blanket
IPC: B41F13/08
Filed: 1977-03-31
Abstract: The rotary printing machine has a blanket cylinder whose surface has a slot to accommodate the ends of the printing plate or rubber blanket. The border to the clamping channel (9) has a flattened region (12, 13) leading towards the channel edge whereby the deviation from the geometrical circumference of the cylinder compensates for the expected bead of the rubber blanket. The flattening amounts to an inclination of some 3 deg. to 7 deg. relative to a tangent to the cylinder's circumference. The flattened surface is formed by grinding such that the distance between the points (14, 15) where the flattening commences amounts to approx. twice the narrowest channel width (b).

Title: Circuit de separation des signaux de luminance et de chrominance d'un recepteur de television en couleurs, et recepteur de television comportant un tel circuit
Inventor: DRIESSCHE MICHEL VAN DEN
IPC: H04N9/78
Filed: 1977-04-01
Abstract: L'invention se rapporte aux circuits assurant la séparation des informations de luminance et de chrominance dans les récepteurs de télévision en couleurs. Contrairement aux procédés connus, où cette séparation s'effectue, après démodulation de la fréquence intermédiaire, sur le signal << vidéo >>, l'invention prévoit de l'effectuer directement après changement de fréquence, au niveau de la fréquence intermédiaire FI. Pour cela, deux branches 31, 32 sont créées dans l'étage FI, l'une comportant un filtre de luminance 33, et l'autre un filtre de chrominance 34, dont les bandes de transmission sont complémentaires; un mode de réalisation particulièrement avantageux fait appel aux filtres piézoélectriques à ondes de surface. Les applications sont notamment du domaine des procédés de télévision en couleurs SECAM et PAL.

Title: Procede de synchronisation de codeurs pour installations de transmission de donnees
IPC: H04L9/12
Filed: 1977-07-13
Abstract: Un premier mot identificateur KW1 déclenche la transmission d'indicateurs de code de l'émetteur au récepteur, pour la programmation d'un générateur de code de réception. L'émetteur transmet un second mot identificateur codé au récepteur après l'avoir correctement diodé, transmet un troisième mot identificateur sous forme d'accusé de réception à l'émetteur, qui déclenche alors la transmission du message codé au récepteur, à l'aide d'un quatrième mot identificateur. La réception incorrecte du second, troisième ou quatrième mot identificateur produit le retour des codeurs dans une position de base, puis la répétition des opérations décrites.
