Patent FR-2249292-A1 (FR)
Title: Direct oil or gas fired water heater - has a central burner in a centrifugal water drum
IPC: F24H1/10
Filed: 1973-10-26
Abstract: The drum is mounted to rotate rapidly about a vertical axis. Water inlet and outlet are formed by stators arranged under the stop and above the floor of the drum respectively. They are circular in shape and are open at the periphery. The outlet stator ends are closer to the inner drum wall than the inlet. The drum is fitted with radial and vertical water guide panels which assist in the formation of a ring or cylindrical layer of water when the drum revolves. The burner projects axially from the top and is shaped so that the flame contacts at least some of the water layer. A rotary vane wheel helps the outflow of water in addition to the existing pressure gradient. Flue channels are formed between the drum and an outer casing. The design optimises heat transfer withou requiring complex condensers or filters.

Title: Tyre vulcanizing mould with heating ducts - in interchangeable radially moving segments which form tread region
IPC: B29D30/06
Filed: 1973-10-31
Abstract: A pressing mould, esp. a vulcanising mould for pneumatic tyres comprises upper and lower rings to shape the side walls and radially movable segments which constitute the outer mould for the tread region and are guided in oblique guides as the mould closes to move inwards onto the tread; the two upper and lower rings comprise heating ducts, esp. of annular shape for heating fluid used in vulcanising. The oblique guides for the tread-region segments are equipped, over virtually the entire height of the segments, with heating ducts for the heating fluid. Pref. these heating ducts are S-shaped or meandering over the entire height of the segment. This arrangement enables the tread to be effectively vulcanised using heat supplied only from fluid-conducting ducts in the radically moving segments; the use of heaters is restricted to the upper and lower ring moulds which do not need to be changed for different sizes of tyre.

Title: Wire drawing bobbin with wire gripping device - has vice type gripping device with radially movable jaw
IPC: B21C1/14
Filed: 1974-06-05
Abstract: The wire drawing bobbin (2) has a device to grip or release the leading end of the wire irrespective of the state of bobbin rotation. The bobbin is power driven to tension the wire and wind it onto the bobbin (2), and finally release the wire coils, and this method of gripping the wire obviates bobbin arrest and enables larger quantities of wire to be handled. The device comprises fixed (31) and radially mobile (33) jaws and a channel which progressively leads wire into the vice. A jack (52) actuated linkage through a hollow bobbin axle (22) effects vice opening and closure and a further linkage moves a rod (61) ensuring positive displacement of wire when the jaws open.

Title: Feed manger for horses - has top edges of sides turned inwards to base
IPC: A01K5/01
Filed: 1974-07-11
Abstract: The manger (1) consists of a sidewall (2) blended in with a bottom (3), preferably moulded in plastic. The top edge (4) of the side wall is curved over inwards. The bottom is in the shape of a right angled triangle with rounded corners and is connected to the three flat surfaces of the side walls which also include holes (9) for the attachment of the manger to a wall. The bottom has a drain hole (12) with a removable plug (13). For ease of manufacture, the side wall are moulded separately in two parts and are joined at (14) by means of two screws (15) in bosses. The latter form ribs, and so serve as reinforcements. The folded over side wall helps to prevent loss of food when the animal is eating.
Patent FR-2239754-A1 (FR)
Title: Contact arrangement for selector switch contact bridge - ensures even current distrib. amongst contacts by suitably shaping fixed contact
IPC: H01H9/00
Filed: 1974-07-30
Abstract: The contact arrangement, for contact bridges having more than eight rail-like contact elements (i.e. more than four pairs), ensures an even current distribution among the contact elements by giving the fixed contact an appropriate shape. The fixed contact has the current input terminal situated at its centre - i.e. at the centre of the parallel array of contact fingers. The width of this input is small compared to the width of the movable contact bridge. The current paths from input to bridge have lengths which ensure an even current distribution by taking into account inductive voltage drops along the paths and the current displacement due to the field produced by the contact elements themselves.

Title: (Alkyl)benzene and paraffin septd. from aq. contact oil residues - obtd. in alkyl benzene synthesis
IPC: C07C2/68
Filed: 1975-04-23

Title: Sphygmometer measuring precisely without intra-arterial application - arterial pulse pressure is transformed to electronic signal, analysed and recorded (SW240177)
Inventor: LINK WILLIAM TREVOR
IPC: A61B5/022
Filed: 1975-07-25
Abstract: Sphygmometer has means to apply a selectively variable pressure in the neighbourhood of a blood vessel. A device measures a fluctuating magnitude which is proportional to the sum of a time-dependent fluctuating component reproducing the pulsating pressure inside the bloodvessel and the selectively variable pressure applied externally to the blood vessel. The fluctuating magnitude is transformed into an electronic signal reproducing a time derivative for at least the fluctuating component of this magnitude. Another device analyses variations in the electronic signal derivative caused by changes in the applied pressure whilst a third device produces an output signal from the analyser indicating the physical condition of the subject under investigation.

Title: Evaporative liq. cooling or concn. - using column with upward atomised liq. flow and air at reduced press.
IPC: B01D3/34
Filed: 1975-08-21
Abstract: A plant for concentrating or cooling a liq. by evapn. incorporates a vertical cylindrical column with a suction fan at the top and a liq. atomiser and an air intake at the bottom. The discharge of the fan goes to a cyclone in which the cooled or conc. liq. is recovered and from which the humid air is discharged. The fan reduces the press. in the column by ca 30 millibars. A syphon connected to the bottom of the cyclone compensates for the depression in the cyclone. The fan is in the top of the cyclone. The liq. atomiser consists of a funnel-shaped vessel with a liq. inlet pipe at the bottom and a constant level pipe. The air is admitted by a pipe which passes through the vessel and has a number of venturi type tubes connected to it. Alternatively it may be a feed pipe entering tangentially a cylinder closed at the bottom and with a disc at the top perforated by a central hole. The plant is more efficient and economical than existing plants because there are no complex and costly contact surfaces as there are in existing cooling towers, and because the operation is carried out at lower pressures than in existing plants.
