Abstract: 670,599. Discharging biscuits from a hopper or hoppers. WRIGHT'S BISCUITS, Ltd. Oct. 11, 1949. [Feb. 2, 1949 ; June 9, 1949] Nos. 2846/49 and 15365/49. Class 78 (i). Means for automatically feeding biscuits out of a hopper or other biscuit-enclosing structure a predetermined number at a time, comprises means 11 for supporting the biscuits spaced in front of the mouth of said hopper, a pusher arm 12 adapted to be reciprocated across the mouth of the hopper, and a brush or other fiexible or resiliently mounted element 13 which is so arranged as to yield under the pressure of those biscuits which are directly engaged by the extractor arms, but to hold back any biscuit which is not directly engaged by the extractor arm. Fig. 1. Biscuits are fed from hopper 10 by reciprocating pusher 12 over surface 11, the brush 13 yielding in the case of a thick biscuit to avoid crushing it. In place of a brush there may be a resiliently mounted gate. Fig. 6. Conveyer 19 or 20 is fed with a row of biscuits from hopper row 18 by reciprocating pusher 21a. If the pusher is made thinner and if it reciprocates between points spaced beyond the hopper row, a row of biscuits may be delivered by the reciprocating movement alternately to the conveyers 19a and 20. Fig. 8. Pusher 22 is Z-shaped and formed with an apron 23 so. as it reciprocates, the left arm thereof feeds conveyers 24 and 26 and the right arm feeds conveyer 25. If the pusher 22 is formed without an apron 23 then a complete reciprocation thereof will feed three biscuits to each of four such conveyers. Fig. 10. Biscuits are pressed forward along sleeve 50, are guided by buffer 53 and then moved to the right by pusher 52, the sleeve 50 being formed with the brush 60. Specifications 670,590 and 670,611, [Group XVII], are referred to.

Title: Flame monitoring apparatus
IPC: F23N5/08
Filed: 1976-01-20
Abstract: 1500771 Photo-electric flame monitors TALENTUM DEVELOPMENT Ltd 20 Jan 1976 [25 Jan 1975] 3329/75 Heading G1A A furnace flame monitor determines the fundamental flicker frequency of the flame and actuates an alarm if the frequency falls below a given level for a given length of time. The monitor comprises a photo-electric head which views a restricted part of the flame via a tube inserted into the furnace; thus tube may be connected to a blower for purging. The signals from the head are amplified by an amplifier whose pass-band covers the flicker frequency range, and are then passed via a Schmitt trigger 17, Fig. 4 to a processor. The trigger provides pulses of standard amplitude to a frequency meter 35, and to two frequency dependant switches, 18 and 31. The switch 18 has a threshold level which is set by a resistor 19, and is followed by a delay unit 20. If the frame frequency falls below the threshold for long enough to actuate the delay unit, this indicates that the flame is unstable; the delay unit operates an alarm via latch 22 and relay 23, and also causes a lamp driver 24 to extinguish a green lamp 30 and light a red one 29. If the flame frequency falls below the threshold of the other switch 31 for long enough to actuate delay unit 33, the green lamp is caused to flash. A switch on the frequency meter 35 allows the trigger frequency or the fundamental frequency of switch 18 or 31 to be measured and displayed at 38. Several photo-electric heads may be used, and multi-plexed into a circuit which determines how many of the heads indicate faulty flames; if there are more than a pre-set number of faulty flames, the alarm relay is operated, Fig. 5 (not shown). Where several heads are used, a corresponding number of frequency dependent switches and lamps are required, but a single frequency meter is used, the head to which it is connected being chosen by operating a switch.
