Title: Installation for natural fermentation of cocoa nibs - in successive perforated tote bins which are mechanically handled throughout
IPC: A23G1/02
Filed: 1980-03-07
Abstract: Installation is for the mechanical handling of cocoa nibs during multi-stage, natural fermentation. The fermentation takes place in the bins of square, horizontal cross section having flat bases with drainage perforations. The installation comprises a succession of parallel, horizontal conveyor tracks with drainage channels extending longitudinally beneath the tracks. Filled bins are advanced intermittently along each track, the contents of each bin being tipped, at the end of one track, into an empty bin at the start of the next track. The emptied bin is recycled to the start of its own track. Prepn. of freshly harvested cocoa nibs ready for dispatch to factories producing cocoa powder and cocoa butter, etc. Comparatively inexpensive mechanisation of previously labour-intensive operations is obtd. The capacity of the installation is easily increased by lengthening the tracks and speeding up the bin pushers.

Title: One-way ball valve for fluid - uses guide sleeve to ensure linear ball movement supported by radial spacers above conical ball seat
Inventor: AMAND ROGER DANIEL
IPC: F16K15/04
Filed: 1980-04-14
Abstract: The one-way valve uses an oscillating ball (5) to control a fluid flow, using a guide sleeve (3) to ensure linear ball movements (M). The internal sleeve (3) diameter may nominally exceed the ball (5) dia. Co-axial pipes (7,8) may converge on the chamber (2) with bore transitions effected by conical tapers (1,11). One taper (1) may form the seat, and radial struts (4) may locate the sleeve (3) centred on the common axis (A). The sleeve (3) may incorporate a counter seat (9) and apertures (10), being sited to house nominally less than half of the ball (5) when on the seat (1). Fluid flows through the pipe (7) to lift the ball onto counter seat (9), continues to flow through an annular vol (V), and acts with the taper (11) to create pressures which keep the ball (5) off the seat (1).

Title: Light operated burglar detector - uses light sensitive resistor to control switching of transistor in circuit responding only to rapid changes
IPC: G08B13/189
Filed: 1980-08-08
Abstract: The light detection circuit for a burglar alarm includes a light sensitive resistor (Rx) in series with a load resistor (R1) which may be selected in the range 470 kilo-ohms to approx. 2 mega-ohms. The common point of these two resistors is connected via a capacitor (C1) to the base of a transistor (T1). When the variation in potential of the capacitor is negative, it is connected to earth, by a diode (D1), but when it is positive it is applied to the transistor base making the transistor conduct. A resistor (R2) ensures that very slow changes in potential do not affect the transistor since current leaks to earth, but rapid changes are effective in making the transistor conduct. The conduction of the transistor (T1) is used in turn to control a second transistor (T11). This controls operation of a relay (10) to initiate an alarm signal. The circuit is not sensitive to slow changes in ambient lighting during the day and night.

Title: Electromagnet transducer capsule adjustment instrument for telephone - uses artificial ear to receive acoustic signal from transducer in magnetic field from solenoid
Inventor: CAPIEZ WILLIAM
IPC: H04R29/00
Filed: 1981-04-15
Abstract: The output of a transformer (9) connected to the mains supply is coupled to a winding assembly (2) in which an electromagnetic transducer (3) is mounted. A thyristor (12) triggered from a control circuit (15) provides a rectified current for the winding. A changeover switch (13) allows the current flow to be inverted. The current amplitude is limited by a resistor (R) to ensure the maximum value of magnetic field is less than the coercive field of the magnetic material in the transducer. In operation, the transducer is driven by a signal generator (5) and the acoustic output from the transducer is received by an adjacent artificial ear (6). The ear output is amplified (7) to drive an indicator (8). A microprocessor coupled to this circuit permits automatic adjustment of transducers to be effected.

Title: Retractable guide for core wires for making a flat multicore cable - to facilitate replacing individual core cable feeds when broken during extrusion sheathing
Inventor: VIAUD ANDRE
IPC: B29C48/06
Filed: 1981-09-15
Abstract: In a process for making flat multiple core cables by extruding twin convergent sheets of insulating matl. on to the upper and lower faces respectively, of a horizontal array of continuous core fibres entering calender rolls, the lateral spacing of the core cables is maintained by a mobile guide comb just upstream of the sheet/roll nips. Each core wire passes through a slot at the nose of the guide, which is tapered to approach between the convergent sheets until close to the nip. The guide can retract longitudinally to facilitate removal of the top cover and rapid replacement of any broken cable(s). Suitable for mfr. of cables with up to 100 core wires of 0.16-6 mm dia. in thermoplastic, thermosetting or elastomeric insulation. The calendar rolls may be profiles to provide a thin web between each pair of core wires. Allows one or more broken core wires to be replaced at an accessible and safe position, quickly enough to avoid disturbance of extruder conditions, while operating the guide close enough to the nip to maintain close alignment with the calender roll channel profiles.
