Title: Modular heating block for central heating and domestic hot water - uses electric heating elements for maintaining water temp. or subsidiary heating system
Inventor: LOQUINEAU JACQUES
IPC: F24H1/22
Filed: 1980-03-05
Abstract: The modular heating block provides hot water and includes a casing (1) forming a reservoir with at least one heating element (3). Connection (5) are provided on one side of the heating element leading to a hot water take-off line and a connection (6) on the other side which is either coupled to the central heating circuit or to the domestic hot water circuit or to a combination of the two. The heating element (3) is pref. positioned horizontally within a sleeve (2) between two halves of the casing (1). The heating element (3) is screwed into place. The heating block can be used in conjunction with a central heating boiler or a heat stove, e.g. for a solar heating system and is used to provide hot water if the boiler is not in use or if the temp. of the water from the heat store is insufficient. Alternatively, the system allows a small part of the total water reservoir to be heated for night-time use. The system is designed to provide an adaptable economical central heating and/or domestic hot water system.

Title: Speed control system for road vehicles - uses spaced magnets set in road to provide pulses in detector comprising logic circuit on vehicle with time interval related to speed
IPC: G01P3/66
Filed: 1980-08-08
Abstract: The control system uses markings on the road consisting of spaced bands lying across the road at a depth of about 30 cm. Each band comprises a number of permanent magnetic elements, and the separation between the bands is proportional to the maximum permitted speed on a particular road. Vehicles are provided with a detector sensitive to the magnetic field above the magnets set in the road. The detector (5) is connected to a time delayed pulse generator (6). Both the detector output and the pulse generator output are connected to an AND-gate (7). Successive pulses from the detector arrive within a set time then the AND-gate provides an output to a recording device (8) indicating that the vehicle is exceeding the speed limit. By using bands with varying spacings different speed limits may be imposed.

Title: Power meter for static training bicycle - has sensors for chain tension and wheel speed, feeding multiplier in which output drives display
IPC: A61B5/22
Filed: 1980-11-07
Abstract: The training cycle, has one wheel driven by a chain, and is fitted with a transducer giving the force transmitted. Another transducer gives the rotational speed of the wheel and an electronic circuit which processes the signals from the transducers to allow the transmitted power to be displayed. The display can also give the speed, or the hypothetical distance covered. The appts. can also be fitted with a weight transducer to give the weight of a patient who can wear a device showing his cardiac behaviour, with all data being given on the single display. The speed sensor gives a pulse on each revolution of the wheel, to actuate two monostable circuits which give respectively signals of fixed and adjustable durations. These signals are summed and the total output charges a capacitor in which the inter-electrode voltage gives a measurement of the linear speed of the wheel.

Title: Automatic spacing of handling heads for bottling plant - uses play in mounting plate for individual head spacing while jacks provide group positioning
Inventor: LEGROUX GILBERT
IPC: B65B21/18
Filed: 1980-11-24
Abstract: A handling head (1) has a square frame (2) with a shaft (3) supported below two opposing members and carried in two collars (4) isolated by rubber blocks (49). Along the shaft are located arms (5) which are able to slide. These carry jaws (5a) operated by a transmission system to compress two cheeks (6) about a bottle neck. The upper part of each arm comprises a sleeve (7) with a stud (8) which passes through a hole (9) in one of two adjustment plates (10). This permits axial displacement w.r.t. the side member. The adjustment of each plate is controlled by a double acting jack (11) in which its piston shaft (12) has a fork (12a) connecting it to a vertical foot (10a). The spacing of each group of arms is effected by the jacks while individual arm separation is effected by using play in the plate hole for positioning the studs.

Title: Muco:polysaccharide fractions derived from heparin - with selective inhibitory action against factor Xa but low anticoagulant activity
Inventor: PERLIN ARTHUR S
IPC: C08B37/10
Filed: 1980-12-15
Abstract: New muco-polysaccharide fractions (I) of high anti-Xa (Yin-Wessler) activity but low anticoagulant activity are prepd. by first suspending in an aq. medium an anticoagulant heparin material contg. both insoluble and soluble components. Some at least of the soluble components have different solubility coeffts. in a water-organic solvent mixt, permitting their sepn. from such a mixt. The resident suspended components are sepd. and the soln. treated with an organic solvent to cause sepn. of one fraction this is generally indicated by development of turbidity. The material responsible for this turbidity is recovered and further addn. of solvent made to the residual solns. esp. until addn. of more solvent no longer causes turbidity. (I) can be used to control particular stages in the blood coagulation process, esp. they have a powerful and specific inhibitory action against factor Xa so can be used in antithrombotic therapy without risk of causing haemmorhage. The toxicity of (I) is so low that the LD50 could not be measured at doses of 3.2g per. kg. in mice.
