Abstract: 1275054 Protective arrangements BRITISH DOMESTIC APPLIANCES Ltd 22 Aug 1969 [29 Aug 1968] 41192/68 Heading H2K The energization of a load, e.g. a motor 1, from an A.C. supply is controlled by a thyristor 2 using a firing circuit B whose firing operation can be modified to change the conduction angle of the thyristor 2 by variation of the potential at a point in the firing circuit B. This point is connected by a diode 18 to a point in a temperature sensitive circuit D which includes a negative temperature coefficient resistor 7. In normal operation the potentials at these points is such that the diode 18 is reverse biased, but when the temperature of the resistor 7 reaches a predetermined value, the resistance of the resistor 7 is so reduced that the potential at the point in the circuit D falls to the level at which the diode 18 becomes forwardly biased and delays or interrupts the firing signals. As shown, the firing circuit B is a pulse producing circuit controlled by an input circuit C. When the diode 18 is forwardly biased a transistor 14 in the circuit B ceases to conduct and the firing pulses cease. The negative temperature coefficient resistor 7 may be placed in intimate thermal relationship with the load or associated with part of the load circuit whose temperature increases with increasing current. Reference is made to the connection of the diode 18 to other points in the circuit B and Fig. 2 (not shown) illustrates an alternative arrangement.

Title: Improvements in or relating to the manufacture of lump or cube sugar
IPC: C13B50/02
Filed: 1960-12-01
Abstract: In synchronized and photo-electrically controlled apparatus for making cube or lump sugar, moist granulated sugar is formed into cubes in an intermittently operating press 1, Fig. 1, the cubes are expelled from the press and moved, by an intermittently operating rake 8, on to an intermittently travelling conveying band 3, which carries the cubes to a dryer 2, where they are transferred, by an intermittently operating rake 17, on to a shelf 16 which is moved through the dryer. The press comprises a rotatable disc-shaped table 4 in which a multiple mould 5 is located in each of the positions A, B, C and D.  Each mould is divided, by partitions 6, into a plurality of similar chambers 7 each containing a piston and having a volume and cross-section corresponding to the desired size of cube. Granulated sugar is fed into the mould in the position A, the table is rotated to bring the charged mould into the position B, where a stop plate (not shown) is pushed over the mould and the pistons are raised to press the sugar into cubes.  The table is then rotated to bring the mould into position C, in which it is not covered by the stop plate, and the pistons are raised to expel the cubes from the containers.  The rake 8 comprises a plurality of pulling plates, e.g. three plates 8a, 8b and 8c.  It is lowered to engage the expelled cubes and then moved to transfer them on to the conveying band 3 in files formed into columns, e.g. three columns 9, 10 and 11 each comprising three files of cubes 9a, 9b and 9c. The cubes in each file are spaced apart by a distance 12 corresponding to the width of the partitions 6.  The rake 8 is lifted and returned to its position over the press. The table 4 is then rotated to bring the empty mould into the cleaning position D. A buffer 13, which extends across the conveying band, is lowered to halt the front ranks of the columns so that the cubes move into close formation in the files and the spaces 12 are eliminated.  The buffer is then raised to allow the closed columns to progress towards the dryer.  The columns are formed into a one-tier block 18 as they are pushed by the plate 17a of the rake 17 on to the shelf 16. The buffer 13 is secured by arms 14 to a rotatable shaft 15 carrying an arm in the form of an armature (not shown), which <PICT:0947600/C3/1> <PICT:0947600/C3/2> <PICT:0947600/C3/3> comes under the influence of electromagnets 24 and 25, Fig. 2, controlled by photo-electric devices 19, 20 in the paths of the columns, Fig. 3.  These devices comprise sources of light 19a, 20a and relays 19b, 20b each equipped with a photo-electric cell and provided, respectively, with coils 19c, 20c operating switches 19d, 20d in the circuit 21 of an auxiliary relay 22 having a coil 22a and a hold-in contact 22c, which actuate a two-way switch 22b supplying current, from an auxiliary circuit 23, to the coil 24a of the electromagnet 24 to move the buffer downwards towards the conveying band, or to the coil 25a of the electromagnet 25 to move the buffer upwards.

Filed: 1959-12-10
Abstract: 863,791. Semi-conductor bi-stable circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 10, 1959 [Dec. 13, 1958], No. 42032/59. Class 40(6) [Also in Group XXXVI] A bi-stable trigger circuit comprises a Hall effect device 1 having three electrodes a, b, c and located in the magnetic field of windings 2, 3 each winding being connected in series with a direct current source 4 across a common electrode c and one of the other electrodes a or b of the device 1. Since the device 1 cannot be perfectly symmetrical more charge carriers will tend to flow from electrode c to one or other electrodes a or b. This will create a magnetic field in the windings 2, 3 in such a direction as to force a large proportion of the current through one of the windings thus saturating the magnetic core 16 (not shown in Figs. 1, 2). The excess current in winding 2, for example, will bias back diode 5 so that a positive pulse fed in via capacitor 9 will drive the current mainly through winding 3, reversing the direction of magnetization and changing the direction of current from electrodes c to b. A symmetrical output is available from points 7, 8. Fig. 2 shows a bistable circuit controlling the position of relay 11 and switched between states by input pulses of alternate polarity. Symmetrical output voltages may again be obtained from electrodes a, b. The circuit shown in Fig. 3 is switched from one state to another by alternate application of positive pulses respectively to the upper and lower ends of winding 15. The alternate pulses may respectively represent a binary one and a binary zero. The circuit is arranged to provide an output pulse at terminals 19 only when changing in one direction, negative pulses being suppressed by the diode 18 which may be biased to suppress unwanted small pulses.

Apparatus for heat-shrinking a plastics film wrapped about an object consists of an endless conveyer having a belt 40 made of metal (e.g. stainless steel), and a heat tunnel 30 positioned over an intermediate portion of the belt top, the tunnel being provided with a hot-air blower 60. During operation, the film-wrapped object is manually placed on a loading station 46 with overlapping edges of the film facing the belt which edges are tacked together by the heat transmitted from a heat-platen 52 underneath the station 46, through the conductive metalbelt. The wrapped object then enters the tunnel where the hot air from the blower 60 shrinks the wrapper round the object, after which the wrapped object leaves the tunnel, and is discharged at station 50. The belt may be made of woven wire in which the longitudinal strand 62 (Figs. 16, 17, not shown) is crimped to increase the longitudinal elasticity of the belt. The belt is supported on a motor-driven roller 36 and a free-running roller 38 spring-biased against the belt to maintain belt tension. The belt tension is adjustable by a screw 99 (Figs. 12, 13, 15, not shown). The edges of the belt are also guided in guide rollers 72, 74 (Fig. 3, 10, 11 not shown). The machine is portable and is operable by an unskilled worker.
