Patent FR-2277753-A1 (FR)
Title: Bulk material discharge machine - has series of compartmented elevator wheels transporting material from bucket wheel
Inventor: ROPER HOWARD FRANK
IPC: B65G67/60
Filed: 1974-07-09
Abstract: The machine is for discharging material from deep holds in bulk carriers, and delivering it into an elevator. It comprises a series of elevator wheels (32, 32', 32") working in conjunction with the bucket wheel (21) and incorporating compartments, arranged in an ascending chain in the frame (37). The contents of the buckets are discharged under gravity into the compartments of the bottom elevator wheel, which in turn discharges under gravity into those of the next one up, the material being finally conveyed away from the top one. The wheels are all driven at the same speed. The wheels can have taper faces, by which they run on taper bearings mounted in the frame.

Title: Collet to hold milling machine cutting tools - has interlocking slotted tapering pieces holding tool in body
IPC: B23B31/20
Filed: 1974-07-25
Abstract: Collet to hold milling machines cutting tools is suitable for use with either threaded or smooth ended cutters. The threaded ended cutter (4) is screwed into a conical slotted retaining piece (5) within the body (1) of the device. It is gripped by pressure applied by another conical, slotted piece (8) pressed inwards by a screwed collar (2). Relative rotation of the components is prevented by protrusions (10). Smooth ended cutters are gripped by replacing the two conical parts by one larger conical, slotted piece, with a parallel inside bore, pressed inwards by the screwed collar.

Title: Cottage cheese mfr from ultrafiltered milk - with coagulation in moulding tubes
IPC: A01J25/00
Filed: 1974-10-08
Abstract: Raw milk is collected in a reservoir; fermentation cultures are added and the milk taken by a pump, through a heat exchanger to bring its temp. to 36-38 degrees C., to the high press. pump which forces the milk through the ultrafiltration column. The filtrate, consisting of lactose and water, is evacuated by a pipe while the concentrate is taken by a pipe to another ultrafilter. The final concentrate goes to the maturing tank from which it is extracted by a pump to pass through a heat exchanger to the mixer, on its way cream and rennet are introduced. The mixt, is still fluid so that it can be introduced into the moulding tubes, which are closed by the cutting blade. The mass coagulates and solidifies; when the outlet is opened, the cheese slides downwards and can be cut as required. Ultrafiltration gives a starting liq. of uniform compsn. The continuous coagulation in the tubes allows portions of cheese to be obtd. immediately and the need for small moulds is eliminated.

Title: Photothermographic process with erasure of unwanted image - by heating exposed emulsion contg. halohydrocarbon andN-vinyl cpd.
IPC: G03C1/675
Filed: 1974-11-05
Abstract: The photographic process employs a matl. coated with a photosensitive mixt. of discrete particles of a halohydrocarbon and an N-vinyl cpd. dispersed in a hydrophilic binder for erasing a first latent image, if it is not wished to develop this, and then for producing a second latent image on the same photographic matl. The matl. is (a) exposed selectivity with actinic light to produce a first latent image, (b) heated to 60-120 degrees C to erase this image, and (c) exposed selectivity with actinic light to produce a second latent image, exposure with actinic light being moderate, so that the latent image is not developed to a visible image by stage (b) alone. The cycle of stages (b) and nc) can be repeated at least once if the second latent image is also unwanted. In addn. to the possibility of erasing unwanted images, numerous images can be produced on different areas of the same matl.

Title: Mechanical actuator for a stepping switch - periodically moving mass step displaces a lever pivotal about two axes
IPC: H01H51/32
Filed: 1974-12-18
Abstract: The switch has two slides, two elements preventing the return of a slide during each acceleration time interval with respect to the other and effecting a partial stroke travel during each deceleration time interval. A stroke integration element acts, during several time periods, in a determined direction and a return element is designed to reset the slide at an original position during absence of periodic movement. The body mass is realised in the form of a section which is transversely circular in at least two directions. Due to the periodic movement of the mass a lever which is in contact with it and which can alternatively swing around two terminal axes arranged on or at the interior of two guide rails, can be displaced step by step.

These supports include a rigid part carrying the hinges of fixing elements and a transparent part which encloses the microdocuments or portions of the microfilm.
Patent FR-2297939-A1 (FR)
Title: Reading pattern matrix for textile fabrics - using pointer to identify matrix position to allow colour to be keyed in to program device
IPC: D03C17/02
Filed: 1975-01-16
Abstract: A pattern matrix for use in wearing or knitting is advanced around a control roller along with a pointer is movable, the pointer being mounted on a carriage connected to a flat endless belt which extends between two pulley wheels at opposite ends of the rollers and one of the pulley wheels being driven. The pattern matrix is indexed over the roller whilst the belt is driven to index the pointer along the roller (i.e. transversely across the pattern matrix). At each matrix position the pointer stops allowing an operator to key in the colour associated with that matrix position. This is effected by e.g. using a series of colour keys associated with the device, the output signals from the keys being e.g. used to program a Jacquard control mechanism. A Jacquard control mechanism for a loom or knitting machine can be rapidly programmed from an initial pattern matrix.

Title: Permanent magnet driven linear or rotary motor - relies entirely on attraction and repulsion forces of permanent magnets to give motive force
IPC: H02K53/00
Filed: 1975-06-24

The application of the motor is intended to be general in that it requires no external supply of energy or driving force. Permanent magnets (6) are included in the approximately triangular cross-section rotor elements (2), the magnets form one outer corner of the triangle and the rotor moves within a cage (1) holding against basically triangular elements in a nose to tail fashion the whole acting as the motor stator. Bearings for the rotor shaft are provided by magnets (3, 4) resulting in a frictionless support, but may also be orthodox ball races.
Patent FR-2317403-A1 (FR)
Title: Loop pile fabric is knitted on Raschelle machine - using guide bar to form a weft yarn into loops
IPC: D04B21/02
Filed: 1975-07-10
Abstract: The machine uses three guide bars, the first guide bar cooperating only with certai needles to form wales of chain stitches. The second guide bar is used to co-operate with same needles and insert zig-zag weft yarns extending between the wales. The third guide bar co-operates alternately with the same needles to form stitches in alternate courses, and with the other needles to produce loops. The distance of movement of the third bar determines the size of the loops produced. The fabric is used as e.g., a wall covering, and can be positioned easily using a hook pile fastener, the loops being engaged by the hook pile. The loops are formed during knitting.

Title: Monolithic integrated circuit temp. compensation - has resistance region whose resistance per unit of surface area is between 300 and 600 ohms
Inventor: SCHWABE GERHARD
IPC: G05F3/26
Filed: 1976-02-27
Abstract: The monolithic integrated circuit for a temperature compensated constant current source uses as a source of reference voltage the difference in potential between two diode circuits. A constant current is obtained by applying this difference in potential to the terminals of a resistance. This resistance is sealised in a semiconducting substrate in the form of a resistant region having a resistance between 300 and 600 ohms per unit area. The resistance per unit area of this region is also equal to the resistance per unit area of the base regions of the integrated circuits transistors. The resistant region is fabricated simultaneously with the integrated circuits transistor base region by means of the planar diffusion technique.
