Title: Improvements in or relating to pulverisers
IPC: B02C19/00
Filed: 1928-04-04
Abstract: 308,095. Broadbent & Sons, Ltd., T., and Hallitt, W. April 4, 1928 impact pulverizers. - The impact surfaces of a pulverizer, against which the material is thrown by centrifugal action, are composed or constituted by the material itself. Two oppositely rotating discs a, b are mounted in bearings a<2>, b<2> and are driven by pulleys a<3>, b<3>. Coal &c. is fed through a tube c to the space between the two discs and after passing through the discs is discharged by a fan i through an orifice (not shown) in the chamber j. The discs are provided with annular concentric rings a<4>, b<4> which are provided with a steep face facing the axis of the mill and with an inclined face on the reverse side. The rings interengage and the space between alternate rings diminishes toward the circumference of the discs. Due to centrifugal force, the coal packs on the steep face of the rings as indicated at d, e, and forms impact surfaces for the fresh coal passing through the discs. The circumferential edge of the disc b is shrouded by an annular ring m so that only the whirl produced by the disc a effects the discharge through the orifice k of any large particles of coal not carried off by the fan i.

Title: Improvements in or relating to television systems
IPC: H04N7/04
Filed: 1939-04-03
Abstract: 527,310. Television. KOLSTER-BRANDES, Ltd., BEATTY, W. A., and CHATTERJEA, P. K. April 3, 1939, No. 10344. [Class 40 (iii)] Rectangular synchronizing signals of fixed amplitude outside the range of the picture signals are time modulated as a function of factors relating to the vision, or accompanying sound, and one edge 13 of the pulses recurs at equal intervals of time and is used for timing the scanning. At the receiver, the pulses are separated by an amplitude filter and used to set up a current or voltage varying with said factors. The modulation is continuously variable and influences the synchronizing impulses at the end of each line as well as those which occur in a black-out period Cl, C2 following (or preceding) a train of pulses in a framing period B1, B2. The pulses control line-scanning generators. Means for observing the time modulation is continuously operative or only operative during the framing black-out period. The modulation may be a function of the average level of the vision signal and be used to supply compensating direct current, if the direct-current component of the vision signal is suppressed, Fig. 7 (not shown). Alternatively the modulation may be a function of expansion or compression of the range of volume of an associated sound signal. According to modifications, the modulation is varied in steps cyclically. The different durations of the modulated pulses may correspond to the periods of transmission of different colours in colour television or to alternate eye-viewing periods in stereoscopic television. Specifications 443,896 and 523,575 are referred to.

Title: Improvements in or relating to carton folding and locking machine
IPC: B31B50/50
Filed: 1956-04-09
Abstract: 808,384. Making cartons. JOHNSON, A. April 9, 1956, No. 10751/56. Class 18. A machine for setting up tray-form cartons comprises a plunger for pressing a blank through a die having at its ends means for interlocking pairs of flaps extending from the carton sides to lie across the carton ends. The plunger 56 reciprocates vertically along guides 42, 43, being biassed to its uppermost position by spring 51, and has a foot 57 with grooves 61-64 enabling it to clear during upward travel the various mechanisms protruding into the die aperture. The foot 57 presses the blank base panel 71 between die projections 113, 114, 116, 117 and 118, 119 which fold up end panels 77, 78, locking flaps 91, 92 and locking tabs 101, 102 in sequence at right angles to the remainder of the blank. As die side portions 121, 122 fold up the blank side panels 86, 87, the base panel 71 is pressed against portions 141 of pivoted members 131 causing can parts 143 thereof to be rotated against the flaps 91, 92 to open their cuts 98, 99. At the same time a bevel on the portions 141 guides the tabs 101, 102 into interlocking relationship with the flaps. To ensure complete interlocking, further movement of the plunger causes the panel 71 to move downwardly levers 154 which are so coupled to further levers 161 that the inner extremities of the latter move downwards at a greater rate than the plunger, pressing on the upper edges of the members 91, 101 and 97, 102 to force them into full engagement. The blank includes optionally a cover flap 32 at one end which is folded inwards by a tongue 176 the tongue being initially pressed clear by the plunger and then springing inwardly above it to engage the flap. As the plunger returns upwards the carton is gripped by levers 191 these levers being initially cammed clear by the descending plunger and springing inwardly at the bottom of its travel to embrace the carton sides in recesses 206. Levers 221 operate in a similar fashion to press the carton sides inwardly beyond the upright position to prevent bulging in the finished carton when the plunger next descends it again cams the levers 192 clear, releasing the finished carton 209 and permitting its ejection by the resilience of its sides co-acting with surfaces 233 of the levers 221.
