Title: Control for peristaltic pump - comprises electric motor speed regulator and pulse generator for very low speed operation of motor and pump
Inventor: BOEUF GUY LE
IPC: F04B49/06
Filed: 1979-09-27
Abstract: The peristaltic pump for medical applications, esp. the control of blood flow during an operation, has two modes of operation. Its speed and consequently the flow rate are variable over two ranges, the ranges being continuous. The higher range is controlled by the variation of the motor speed, the lower range by the application of variable frequency pulses to the motor. The two methods of control are linked to a single control (B) geared to potentiometers. A pulse generator (G) feeds pulses to a shaping circuit (F1) and amplifier (C1) when the switch (P1) is closed. These pulses are applied to the motor. A second similar system (G,F2,C2,A2) provides pulses of opposite polarity to stop the motor immediately after each drive pulse. This prevents the motor continuing because of the inertia of the drive mechanism. The switches (P1,P2) are operated via a cam mechanism attached to the shaft of the single control button (B), thus providing continuous variation over a wide range - typically 1 to 400 ml/ minute.

Title: Bicycle chain drive sprocket of variable ovality - opt. made of polyamide and with wear-resistant coated teeth
IPC: B62M3/06
Filed: 1979-11-23
Abstract: The prim. sprocket for driving a bicycle chain is made from segments of a rigid material, e.g. steel or Al assembled with adjustable linkages so that the rider can control the alignment and degree of oval distortion which can be developed at the sprocket perimeter. The rider can establish a more uniform level of chain drive tension to be derived from the twin angular displacements involved during each cycle of the pair of pedals connected by cranks to the sprocket. The teeth are shaped to maintain engagement with the chain despite variations in sprocket ovality. Pref. the sprocket is made of an elastic rigid material (nylon type), and the teeth are coated with a wear-resistant material.

Title: Charged particle beam orthogonal electromagnetic deflection system - has network between deflection current generators to provide sequential delays in response to synchronisation pulses
IPC: G21K1/093
Filed: 1980-02-26
Abstract: The system is used to deflect the charged particle beam provided by a particle accelerator (8) across the output window (2) of a vacuum chamber (3) coupled to the latter. The transverse and vertical deflection is obtained by respective electromagnets (1,4) receiving corresponding deflection currents with the synchronisation input of the transverse deflection current generator (6) coupled to a synchronisation output of the vertical deflection current generator (5) via a delay network (7). The delay network (7) receives a synchronisation pulse when the current in the vertical deflection winding (1) is a max. and it exhibits a sequence of delays differing by a constant increment defined by the particle beam dia. divided by half the vertical deflection frequency multiplied by the max. vertical deflection. The number of delays is inversely proportional to the transverse deflection frequency. The working life of the foil across the output window (2) is increased.

Title: Shellfish larvae collection container - uses collector surface with strong flexible core coated with rigid friable material to which larvae attach
IPC: A01K61/54
Filed: 1980-03-04
Abstract: The collector is for the brood larvae of oysters or mussels and rears the shellfish which they produce, in order to establish rearing or growth zones. The larvae are collected on large-area rectangular surfaces, and after sufficient time has elapsed for the formation of the young shellfish, the latter are detached from the surfaces. The surfaces comprise flexible cores (1) of high mechanical strength and a friable rigid external coating to which the larvae attach themselves. On harvesting, the collector surfaces are subjected to torsion, bending and/or tension, causing detachment of the coating and its disintegration into a large number of pieces to which the shellfish are attached.

Title: DC or rectified AC motor - has two cylindrical rotor sections with longitudinal notches cut between pole faces
IPC: H02K25/00
Filed: 1980-06-19
Abstract: The DC or rectified AC motor includes a cylindrical rotor on a shaft with three pairs of stator poles directed inwards towards it. The stator poles are in pairs, one of each pair being adjacent to one part of the rotor, whilst the other pole of the pair is adjacent to the second part of the rotor. The rotor has a series of notches cut parallel to the axis of the cylinder, with uncut projections forming the cores on which coils are wound. The coils are connected to two collecting rings at one end of rotor shaft. Diodes mounted in a bridge circuit are connected in parallel with the commutator between the supply terminals feeding current to the machine, and the connections for the stator windings. Where there is a north pole on one section of the rotor, there is a south pole on the adjoining section of the rotor, the two poles interacting with the corresponding two poles of a stator section.

Title: Spray coating gun for plastics and paints - uses coaxial mixer, component feed and link channel and positionable nozzle channel to permit purging
IPC: B05B15/50
Filed: 1980-07-21
Abstract: Spray coating gun for plastics, paints, adhesives etc has two separate component channels plus swivel nozzle with mixing chamber with as many channels as componentsand has been modified to permit individual feed of the components for purging purposes. The mixing chamber and the channel (I) for one of the components together with the linking channel between them in the nozzle are all coaxial. Channel (II) passing through the nozzle is positioned such that it registers with the second component feed channel (III) and connects this to the atmosphere by swivelling the nozzle relative to the main gun body. The nozzle should present a rotor whose pivot axis is normal to the chamber axis or coincides with the chamber axis. To purge the gun and nozzle this is turned 180 deg without using trigger so that the chamber still links with the channel (I), and channel (III) connects to the through channel (II) but disconnects from feed-channel. When the trigger is pressed, the channel (I) component vents to atmos. through the chamber and the channel component vents via channel (II), without the two components mixing.

Title: Powder for sealing electrical cables against ingress of moisture - comprising powder which gels or swells on contact with moisture and powder whose particle size is function cable core interstices
Inventor: FOUQUE MAURICE
IPC: H01B7/288
Filed: 1980-07-29
Abstract: Powdered prod. for ensuring the tightness of cables against ingress of moisture comprises (a) a powder which gels on hydration and/or a powder whose vol. increases considerably on hydration; and (b) a powder whose particle size is a function of the dimensions of the interstices of the cable core. Typical powder (a), which gels on hydration, is of carboxymethylcellulose (CMC) or polyethylene oxide. Powders (a) which increase in vol. on hydration are e.g. pulverised clay, esp. bentonite. Powder (b) is pref. wood powder, esp. sieved non-resinous wood powder with a particle size corresp. to 10-25% of the dia. of the interstices in the cable core. A specifically claimed compsn. comprises CMC, bentonite and 20-60 wt.% wood powder. The powder fillings are useful in multicored communications cables, etc., for preventing the passage of water and moisture vapour along the cable in the event of ingress of this into the cable. Unlike previous powder cable fillings contg. (a) alone, the presence of (b) causes a blocking effect on the rapid ingress of water which prevents (a) being carried long distances along the cable before the hydration effect causes sealing. In this way, damage to the cable is confined to a small length and the cost of repair is minimised.
