Patent FR-2231873-A1 (FR)
Title: Jack with two-way adjustable piston travel - has hollow piston rod with two rotatable threaded adjusters
IPC: F15B15/24
Filed: 1973-06-04
Abstract: A cover protects the means of adjustment from impacts and also serves to lock them in position. The two adjusters are adjacent to each other at the rear end of the jack and are co-axial with the jack cylinder. Adjustment is carried out by turning one or the other of these parts about its axis, in one direction or the other, without the necessity of dismantling the machine. The rearward travel of the jack piston is limited by a stop, the position of which can be adjusted. Forward travel is limited by a movable front stop.

Title: High speed weighing machine for rows of horizontally moving objects - has parallel diaphragms coupled to platform with supports and sensing loading
IPC: G01G21/00
Filed: 1973-06-06
Abstract: The diaphragms are mounted one above the other in parallel with an intervening space and fixed to a support system. These are rigid couplings at a distance from the supports. The weighing platform is horizontal and fixed to the coupling along a vertical axis. The load activates a measuring element which reacts to vertical loading of the couplings. This provides a means of determining the wt. of the body on the platform. The diaphragms are of phosphor bronze or stainless steel.

Title: Juice extn. process using horizontal wine-press - with continuous controlled feed, giving improved quality wine
IPC: B30B9/12
Filed: 1974-01-30
Abstract: Juice extraction process and plant, with a continuously fed wine-press, comprises a perforated cylinder with an internal endless screw, the shaft of which is driven by the motor. The end of the cylinder is closed by a door; this is operated by a jack and will not allow the pressed grapes to escape except as a function of the press. on the door. The press is fed by a pump with its outlet connected to the rear end of the cylinder. The endless screw can be rotated by its shaft but it can also be driven in axial displacement by a jack. In operation, the grapes are carried into the compression chamber by the endless screw with the scre rotating but fixed axially. Prod. in the chamber is then compressed by the axial movement of the screw while its rotational speed is very low or nil. The juice is extd. and the residue expelled; the screw being withdrawn and the cycle re-started. The new process improves the quality of the wine; and it can be used in all cases including the prodn. of high quality wines.

The inlet is connected to a chamber to which the gas is supplied and the pressure in the chamber is amplified and measured to determine the presence of the yarn in the guide duct. The device works consistently and is cheap. It not only detects the presence of the yarn but can also test for variations in diameter.
Patent FR-2273575-A1 (FR)
Title: Clearing and preserving filter cloths - by compressed gas e.g. air, contg. solvents, detergents, silicones, anti-corrosion materials
IPC: B01D33/00
Filed: 1974-06-10
Abstract: A process for clearing solids from, and for preserving, filter cloth, which is used in the form of an endless band moving over rollers, consists of directing a gas, perpendicularly over the whole width of the cloth on the return part of the band, after the cloth has been used for filtration. The gas may be air and may contain aerosols which incorporate clearing agents such as solvents and detergents and preserving agents such as silicones and anti-corrosion products. The appts. for carrying out the process is a cylinder rotating at the same speed as the cloth and a fluid pulsation device increasing the air flow. The cylinder is supported against the cloth within the return section and is made of rigid metallic mesh, surrounded over the part not in contact with the cloth by a casing which conducts the gas. Alternatively, the cylinder may have solid walls, in which case two ramps are fitted, one on each side of the cylinder, arranged to pulse the fluid towards the contact zone. The cylinder may be rotated by the filter cloth itself or by a motor. There may be several cylinders to distribute the fluid over a large area. The method economises on water consumption and removes the risk of pollution due to recycling of wash water. It gives greater filtration capacity than existing installations.

Patent FR-2296304-A1 (FR)
Title: Noise reducing circuit for magnetic recording - allows reduction between 20 and 60 db. and uses compression and expansion techniques
IPC: H03G7/08
Filed: 1974-12-26
Abstract: The circuit arrangement provides a 20db to 60db reduction in the noise levels incurred in electrical signals during magnetic recording particularly but due to micro-groove recording. The technique utilises a signal compression circuit before recording and a matching expansion circuit following readout. Recording is via a logarithmic amplifier based on an operational amplifier circuit associated with a matched (NPN, PNP) pair of transistors connected in parallel, collector to emitter, providing the non-linear characteristics required for the logarithmic operation and the exponential operation of a similar circuit provided for the readout. Bias to the transistor bases is a function of the signal level allowing extension of the technique to very low signal levels.

Title: Tools for moulding sharp seal channels within plastic pipe sockets - by forming between a sleeved mandrel and a split mould
IPC: B29C57/02
Filed: 1975-12-18
Abstract: Appts. for moulding an annular channel within the socket end of a thermoplastic pipe comprises a combination of an internal mandrel and an external split compression mould. The mandrel comprises a core supporting an array of (four) split sleeve segments which are shaped to define the internal profile of the channel. The mould is shaped to define the external profile of the channel. After moulding, the mandrel sleeve segments can be extracted after removal of the core.

Title: Depositing solder paste on electric components - using dosing machine where plungers transfer blobs of paste onto components
IPC: B23K3/08
Filed: 1975-12-18
Abstract: The parent specification described a device for depositing solder paste onto localised points on components used in electric signals to telecommunications. This is now carried out using a frame carrying a stationary plate on which dosers are mounted. A work cylinder lifts a tank contg. solder paste so the dosers ar filler, and the tank is then lowered in synchronisation with dosing plungers which dip into the dosers and pick up the required amt. of paste. The dosing punches are then raised and moved horizontally towards the workpiece while the dosers are refilled by raising then thank to repeat the cycle. The present device is simpler to make and easier to operate than that described in the main patent.

Title: Washing machine drum stop unit - has posn indicator linked to motor electronic control circuit to stop drum at same place (NL200776)
IPC: D06F37/30
Filed: 1976-01-14
Abstract: An apparatus is claimed to bring the drum of a washing machine to rest at a pre-set position every time the machine is stopped, where an electronically-controlled motor is used to power the machine. The motor shaft is fitted with a ring braking surface which operates in conjunction with a spring-loaded brake pad which is pulled by a brake-lifting magnet from the braking surface against the action of the spring. A position indicator is fitted to the static machine housing and the drum to give the control signal to the electronic control circuit of the motor. The system ensures that the drum is consistently brought to rest at the same position whenever the washing machine is stopped, to ensure that loading and unloading are not impeded.
Patent FR-2311092-A1 (FR)
Inventor: ANTONOV S F
IPC: C12H6/02
Filed: 1976-05-14
Abstract: A novel process for preparing spirits is described in which whey is used as the carbohydrate-containing starting material. The whey is fermented by yeasts of the genera Candida or Torulopsis at a temperature of 28-30 DEG C; subsequently, the ethyl alcohol is separated off by fractionation, rectified and purified from protein degradation products. The ethyl alcohol is then diluted with a whey, which has been freed from proteinaceous material down to a maximum content of 0.05% by weight, to the alcohol content of 30-45% by weight which is desired in the final product. The process according to the invention prevents carbohydrate-containing products, such as cereal, potatoes or sugar beet, which are required for human nutrition, from being used for preparing spirits, and, instead, a product produced in excess in the dairy industry is utilised. With regard to their quality, the spirits obtained are equivalent to the products prepared by previously known processes.
