Title: Turbine blade with hard protective plate - has contact surface between spiral forming portion of cylindrical surface
Inventor: VERRIER ROGER
IPC: F01D5/28
Filed: 1975-02-28
Abstract: The turbine blade has on its edge, against which the driving medium acts, a small protective plate of hard material held in place by brazing. The contact surface (4) between the blade (1) and plate (3) is a spiral portion of a cylindrical surface. It is particularly for use in the final stages of a steam turbine, and compared with existing designs has the advantage that frequent manual adjustment is unnecessary after the brazing operation. The plate can be produced by precision grinding of a casting, or by cutting out a part of a suitable cylinder.

Title: Vidicon tube target image analysis - is performed with compensation provided for defocussing of reading beam using logic circuit
Inventor: GUYOT LUCIEN
IPC: H04N5/228
Filed: 1975-10-17
Abstract: An image is formed on the target of a vidicon tube and is read by several electron beams sweeping it point by point. The signals are analysed and compensation provided for defocalisation of the reading beam. a logic circuit (3) controls a generator (4) to determine the times during which the target of an analysis tube (1) is swept by a focussed beam and a defocussed beam. The video signal from the tube is preamplified (5) and passed to two amplifiers (6,7) with inputs gated from the logic circuit so that the respective beam signals are amplified separately. The signals are mixed (9) after one (7) has been memorised (8) to provide a standardised delay for the particular TV system line sweep frequency.

Title: Pedal operated refuse bin - has inside container which is pushed up by pedal and actuates lid
Inventor: DAGONNET DANIEL
IPC: B65F1/16
Filed: 1975-11-13
Abstract: The inner container of the pedal bin has a stiffening flange at the top. The container also has a reinforced base. The container fits inside a sleeve which also has a flange at the top so that the container can rest on the flange of the sleeve. The sleeve has a pedal which is pivoted on a pin in the base of the sleeve. When the pedal is depressed the container is raised. As the container rises, the flange on the container comes into contact with a rib (6) on the lid (4). The lid is hinged to the outside of the sleeve (5).
Patent FR-2333714-A1 (FR)
Title: Plastic screw sleeve for closing bottle - has shear off collar to provide seal after bottle is initially opened
IPC: B65D41/34
Filed: 1976-02-02
Abstract: The screw-on top for closing bottles is made from plastic. It consists of the screw sleeve (1) inside which the internal thread (2) is located. A collar (7) is attached to the leading end of the screw sleeve (18) by a location flange (12). A shear -off ring (8) is linked to the collar (7) by thin radial webs (9). When the bottle is opened for the first time, the twisting action on the screw top (1) breaks the thin webs (9). Thus the screw top can be removed whilst the shear ring (8) is retained by an external flange on the bottle screw. A loose shear ring therefore proves that the bottle has been opened.

Title: Dust free packet filling system - has air exhausted via porous wall section before sealing with label
IPC: B65B39/10
Filed: 1977-01-28
Abstract: The dust-free filling and venting and/or evacuation system for packets holds the empty packet by two lateral jaws (6) round a flexible mouth-piece (9) to form an airtight seal. The lower part of the mouthpiece is held shut by plates hinging (8) together and which cause it to distort. It is then expanded by the plates to form a mouth, through which the material flows into the packet. The air entrapped in the packet is then withdrawn by a suction cup, connected to an exhauster, via a special porous area formed in the packet wall. This is then sealed up by the application of varnish or gluing a label over it, or by fusing the outer surface.
