Title: Centrifugal sediment extraction system - sediment is separated from wall and discharged axially from inclined surface
IPC: B04B1/20
Filed: 1973-11-09
Abstract: Sediment is extracted when it arrives in a collector zone of the peripheral wall on separation from the mixture. It is separated from the wall and returned to the centre out of the liquid, and then projected by the centrifugal force against an inclined surface so as to be discharged axially. To give an additional drying effect the sediment can be projected centrifugally against an inclined filtration surface. Vaned wheels mounted inside the rotary centrifuge bowl rotate against its end wall about axes nearer to the peripheral wall than to the axis of rotation of the bowl, and are connected to a drive causing the vanes to scrape the peripheral wall.

Title: Digital output weighbridge - has beam, load-carrier, and motor driven cursor with output disc encoder
IPC: G01G23/36
Filed: 1973-12-07
Abstract: The weighbridge has a beam carried by a knife-edge. The beam has on one side of the knife-edge a load-carrier and on the other side a cursor which can be driven along the beam by a motor. A device which detects when the arm carrying the cursor is at its high or low position is used to drive the motor so as to bring the beam into a stable position of equilibrium. An equilibrium detector stops the motor. A disc encoder rotates according to the displacement of the cursor along the beam and produces signals sent to a logic circuit processing them into numerical information corresponding to the position of the cursor on the beam to obtain a measure of the load at the load-carrier.

Title: Firearm detection and screening system - permits entry to check zone, bars progress if firearm detected
IPC: E05G5/00
Filed: 1974-12-19
Abstract: A firearm detection and screening system has a turnstile at the entrance (3) which allows only one person at a time to enter the detecting area.

Title: Shuttleless loom weft feed roller - has sensor which measures yarn length and causes excess yarn to wrap round roller during picking
IPC: B65H61/00
Filed: 1975-02-07
Abstract: Weft is fed to a shuttle-less loom over a feed roller rotated by the loom drive mechanism and with which a presser roller co-operates to maintain the weft in contact with the feed roller. A sensor finger projects through pref. a slot in the drum surface and is actuated by a double cam pref. located in the roller so that after a predetermined length of weft yarn has been fed to e.g. an hydraulic or pneumatic picking device the sensor finger engages the weft and causes it to wrap around the feed roller whilst picking of the preceding length of weft yarn takes place. Accurate measurement of lengths of weft yarn fed to the picking device is achieved.

Used in mfr. of fat-enriched powder, esp. skimmed milk powder enriched with an animal or vegetable fat such as lard, tallow, palm oil, coconut oil etc., partic. for feeding calves. High ratio of prod. output to air usage and energy requirement compared with spray-drying tower process.
Patent FR-2264477-A1 (FR)
Title: Method of milking cows - involves reducing frequency of pulsations when milk flow falls to set amount
IPC: A01J5/007
Filed: 1975-03-19
Abstract: The milking unit (1) is connected to a device (3) indicating the milk flow through a milk pipe (2). As soon as the quantity of milk passing through the device (3) drops below a set amount per unit time, electrodes (4) regulate the pulsator (6) to a lower frequency of pulsation by means of a control mechanism (5). The frequency of pulsations is lowered to give about five pulsations per minute. At the beginning of milking, the frequency of pulsations of roughly five pulsations per minute increases progressively until it reaches the normal milking frequency. A selector switch regulates the reduction in pulsation frequency.

Title: Catheter with flexible extension - comprises two telescopic tubes sliding along extension tube and flexible extensible protection envelope
IPC: A61M25/01
Filed: 1975-03-27
Abstract: The flexible extension has an insertion end for fitting in a body opening to allow drainage of organic fluids. Two tubes can slide along the extension, one extending beyond the end of it and forming a sliding extension of the other one, which is sealed to the extension at the distal end, while the two tubes can telescope together to assist insertion in the body. A flexible extensible protection envelope extends for the full length of the extension, being sealed to the two tubes so as to cover the tube telescoping zone completely and maintaining a sterile environment round the entire extension surface. The distal end has an orifice beyond the envelope for drainage of organic liquids. The extension slides in the lengthwise direction in relation to the envelope, which is retractable to allow this and insertion in the body.

Title: Fork lift truck accessory - has ram operated trapezium linkage with vertical axes between truck and fork mounting
IPC: B66F9/14
Filed: 1975-06-03
Abstract: The forklift truck accessory mechanism enables it to set down and pick up loads in difficult positions, particularly in corners and against walls. The fork mounting forms, in the central position, the small base parallel to the front of the truck of a trapezium, like the small one, is symmetrical in relation to the truck centre line in the central position, and is formed between two vertical pivot pins in the truck lifting mechanism. A ram, controlled from the driver's seat, can be provided to distort the trapezium, either by lengthening or shortening its diagonal, or by shifting the small base sideways by means of a finger. This shifts the fork sideways, and slews them, for a limited amount.
Patent FR-2277962-A1 (FR)
Title: Device fixing hinge bearing to glass door - has glass sandwiching plates allowing hinge support insertion either side
IPC: E05D7/02
Filed: 1975-07-09
Abstract: The device uses horizontal screws engaging apertures in one of the glass sheet sandwiching side plates, and features the ability to locate screws on the door interior, whether the door is of left or right hand hanging type and allows hinge bearing plate insertion either side. The geometry of the side plates is such that when fitted together their form hinge bearing plate reception cavities which are symmetrical w.r.t. the central plane of the glass sheet and fashioned in the external faces of the side plates. Side plate assembly provides symmetrical cavities since one side plate reveals a 'T' shape recess when viewed it transverse section with a perpendicularly projecting bar.

Title: Screw clamp for bare conductor - has screw shank with collar that breaks off and rotates to prevent torque transfer to conductor
Inventor: BLINDAUER ROGER
IPC: F16B35/04
Filed: 1975-12-29
Abstract: The screw clamp, for a base conductor, consists of shank (a) and a head. The end of the shank has a neck (b) and a collar (c) fixed to the neck via narrow bridges. The shank, neck, collar and bridges are all one piece. The conductor (not shown) is clamped against a support face (not shown) by the end face (C1) of the collar as the screw is screwed into the contact block (not shown). As the pressure on the conductor increases the collar bridges shear through and the collar drops around the neck. As the screws continues to rotate, the collar remains stationary on the conductor and acts as a bush for the neck of the screw - thereby preventing the screw torque being transferred to the conductor.
