Title: Drive circuit for household refuse disposal units compressor motor - has reversal-setting thyristor in series with direction-reversing relay
IPC: B30B9/30
Filed: 1975-05-29
Abstract: The drive circuit has a relay to reverse the direction of the motor when the latter experiences a given loading - i.e. when the refuse has been compressed sufficiently. A thyristor (43) is connected into the circuit of this reversing relay circuit (45) and is controlled by an auxiliary voltage derived from intermediate circuits (B, C, D). This auxiliary voltage allows the thyristor to set the point at which the motor is reversed in direction, and can itself be set very simply by switches accessible to the user of the disposal unit. The motor may drive the compression piston via a parallelogram linkage.

Title: Domestic central heating pump with adjustable flow - has discharge volute at side of impeller
Inventor: LELEU CHRISTIAN JEAN
IPC: F04D29/42
Filed: 1975-06-23
Abstract: The pump has an electric motor which drives the impeller (10). The pump casing (16) has an internal step or ledge in front of the impeller which inclines spirally away from the impeller and forms one wall of the discharge volute (14). The flow regulator (43) is a cylinder which inserts into the casing in front of the impeller and carries a projecting flange (33). This flange forms the other wall of the discharge volute. The regulator can be turned manually by a handle (42) outside the casing and by changing the section of the volute varies the flow characteristics of the pump. The arrangement of the volute in front of the impeller makes the casing easier to cast and reduces the size of the pump.

Title: Push button operated safety switch - has contact actuating lever in form of rigid magnetisable swivelling armature
IPC: H01H3/50
Filed: 1976-02-03
Abstract: One end of the push-button carries an elastically deformable strip whose other end is free. A lever operates a moving contact cooperating with a stationary contact in the switch housing.

The lever is in the form of a rigid magnetisable armature (17), pivoting in the housing (9, 10) and cooperating with an electromagnet (14, 15). The latter coil (15) is fed via the switch output (4) and a bimetal switch (7) acting as an overload detector and forming a holder for the armature. The latter is engaged by a rocker (5) in order to effect its lifting from the electromagnet.

Title: Calcining plant for cement raw material - prior to clinkering, has inlet at bottom and outlet at top
IPC: F27B7/20
Filed: 1976-02-12
Abstract: Heat treatment plant comprises a vertical calcining furnace consisting of an upper cylindrical part with a tangential entry port for particles of material in suspension in a gas or air current and a fuel jet. The furnace has a common exit for the gas and for the heat treated material at its upper end and an entry for air and/or hot gas at its lower end. Since the particles are rising up the furnace against the force of gravity, the furnace height can be reduced compared with known plant in which the reverse is the case, for the corresponding calcination time.

Patent FR-2306373-A1 (FR)
Title: Hydrodynamic brake with spring loaded control valve - uses spring to shut off liq pressure in pressure line
IPC: F16D57/06
Filed: 1976-03-29
Abstract: The hydrodynamic brake has an annular channel (11) whose flow (12) has a variable influence on the pressure in a fluid take-off line (13) and hence on the volumetric efficiency of the brake. This influence is achieved by a wall profile (14) on the offtake to the leading to the take-off line. Through-flow resistance in this line is achieved by a spring-loaded valve (16) whose spring seeks to close the valve against the fluid pressure in the take-off line. In order to achieve different levels of braking moment the spring can be stressed to different levels using an abutment (18). An adjustable permanent outlet (19) is positioned next to the valve and provides an additional fine adjustment for the level of braking moment.

Title: Joining ends of sealing rings - uses T=shaped elastomeric block between seal ends to facilitate mfr. of rings to suit shafts of any dia.
IPC: F16J15/32
Filed: 1976-05-04
Abstract: Sealing rings, to suit shafts or pistons of any diameter, can be made by using a special joining piece (10). The joining piece, which is made from a suitable elastomer, has a cubical central section (16) with two arms (11). The upper surfaces of the arms (11) are shaped to an angle of about 45 deg. at each end (12). The joining piece is fitted between the ends of a length of square section elastomer extrusion which is cut to suit the diameter of the shaft to be sealed. When the ring is placed in the sealing groove the walls of the groove compress the joining piece (12) against the extrusion to achieve a perfect seal.

Title: Triangular end section plastics carrier bag - is made as block bottom bag with handles to receive cardboard base insert
IPC: B65D33/02
Filed: 1976-05-07
Abstract: A plastics carrier bag is made in the manner previously used to make a block bottom bag, and a rectangular cardboard insert (30) is placed inside to form a flat reinforced base. When the handles (17) are pressed together, the shape is then triangular in end view, designed to hold and protect clothing. The bag is made from an open ended plastics sleeve, which is folded inwards to form a pleat down each side, and the handles fitted and welded on. The bottom is folded over, leaving two triangular folded flaps extending sideways from the base. These are cut off, and the cut edges welded to form a block bottom. Finally the adhesive coated cardboard piece is inserted inside the bottom.

Title: Long stroke single or double acting ram - has piston coupled by flexible metal strip passing through breech end to actuator slide
IPC: F15B15/08
Filed: 1976-05-20
Abstract: The long-stroke single- or double-acting ram has a piston working in a cylinder between two breech ends. The thrust of the piston is transmitted by means of flexible metal strips passing through seals in the breech ends, and then through 180 deg. round guide rollers mounted on the breech ends and attached to the ends of the actuator slide. The strips can be anchored to the piston by means of a pin having flats at the ends against which the strip ends are clamped, and offset from the piston centre line. A semi-circular groove is machined in the drilling wall and also in the pin, accommodating a set of metal balls, so as to secure the components in the axial direction while allowing them to pivot in relation to each other.

Title: Stabilising bar for free standing wall form - is used in reinforced concrete construction and acts as lever arm preventing form from overturning in wind
IPC: E04G19/00
Filed: 1977-03-16
Abstract: The stabilising bar is for use on wall shuttering and prevents free-standing single-face forms from overturning in the direction of the formed surface. The bar may be deployed on the site of reinforced concrete wall construction, and eliminates danger due to the wind etc. when one form stands alone in prepn. for the installation of the form to the opposed face. The bar (2) slides in an oblique transverse hole (1) in the base of the form and acts as a simple lever arm resisting overturning. The hole (1) in the form is inclined to the horizontal and may eventually be used to locate a cross tie of lesser dia. The bar (2) may have a handle loop (3) in its aft extremity and which also serves to limit the penetration of the bar.
