Title: An improved method of and apparatus for applying lining compound to closures for containers
Inventor: BRITTAIN JOHN HOWARD
IPC: B29C31/04
Filed: 1952-01-01
Abstract: <PICT:0710445/III/1> <PICT:0710445/III/2> <PICT:0710445/III/3> <PICT:0710445/III/4> Lining compound is applied to a closure for a container by introducing the compound into a continuous open-sided channel formed in an applying device and having a contour corresponding to that of the closure area to be lined, disposing the applying device over the closure so that the area to be lined is aligned with the open side of the channel, and constricting the channel to expel the compound therefrom against the closure area to be lined. As shown, the applying member consists of outer and inner cup-like cylindrical shells 4 and 17, the inner member 17 being spaced from the outer by studs 18, and annular space being formed between the members in which the depending portion 20 of a piston 19 can slide.  A hollow member 5 extending from the closed end of the shell 4 is slidable vertically in a bearing 7 of a bracket 8, on the machine bed or frame 9 and supports an arm 10 carrying a roller 11 which is urged by springs 15 against a cam 12, which is caused to rotate, e.g. by a chain-driven sprocket 14.  The piston 19 is supported on a rod 22 which passes through the hollow member 5 and is connected with a link 23, having a slot 24 co-operating with a pin 25 secured to the cam 12.  A bath 27 of lining compound, the level L of which is maintained substantially constant, is secured to the underside of the bed or frame 9, the open top of the bath being exposed to permit the compound applicator, formed by the outer and inner shells 4 and 17 and the piston 19, to receive compound, but being obturated by a shutter 28 on which the lid to be lined is supported, during the lining operation.  The sequence of operations, as determined by the cam 12 and pin-and-slot 25, 24, is as follows:-(1) the applicator is contacted with the surface of the lining compound, with the piston 19 at the bottom of its stroke; (2) the piston is raised, causing the compound to be sucked into a channel formed by the annular space 21 and the bottom of the piston 19; (3) the applicator is raised from the bath, and a lid 1 is positioned beneath it, supported by the shutter 28; (4) the applicator is brought into close proximity with the lid 1, and the lining compound is discharged by downward movement of the piston 19. The applicator is then raised in readiness for the next cycle.  In a modified form of applicator (Fig. 6), there is a cylinder 4a for attachment to the hollow member 5, and housing a piston 19a supported by a piston rod 22 for reciprocation by the link 23. The outer end 33 of the piston is flared outwards, so that its surface 34 and the end face of the cylinder form an annular gap 21a when the piston is moved away from the closed end of the cylinder; this gap becomes filled with compound when the applicator is lowered into the bath thereof, closure of the gap in the subsequent lining operation depositing the compound on the vertical sides of the lid.

Filed: 1985-02-18
Abstract: An apparatus for optical examination of eggs comprises a first transducer unit 45A with a sensitivity range of 400- 500 nm corresponding to the absorption spectrum of egg yolk and a second transducer unit 45B with a second sensitivity range of 500-700 nm, also within the visible range but not overlapping the first region. The first transducer unit can therefore detect egg shell but not egg yolk, while the second transducer unit can detect both shell and yolk. When the first unit 45A does not detect shell at the same time as the second unit 45B detects yolk, the conclusion is drawn that the egg white contains yolk, even if the white contains shell. The two transducer units are prevented from detecting egg white by a polarized light beam being directed towards and reflected from the egg white but is shut out from the transducer units by means of an analyzer 41 with a polarization axis which is at right angles to the direction of polarization of the light beam. <IMAGE>

Abstract: 1,078,829. Vocoders. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 29, 1965 [April 6, 1964], No. 13170/65. Heading H4R. In a vocoder system each spectrum channel is sampled once per cycle of the fundamental frequency of the speech signal and the resulting signals transmitted in digital form. Fig. 1 shows a preferred embodiment in which speech from a microphone M is divided into a number of frequency bands by band-pass filters BP the signals from which are rectified by rectifiers G and passed through low-pass filters TP 1  to form analogue signals corresponding to the variations in energy of the individual frequency bands of the original speech. The speech is also fed through a low-pass filter TP 2  to a zero crossing detector ND to develop a pulse at the fundamental frequency of the speech. The fundamental frequency pulse is fed through a delay unit VZ, comprising e.g. cascaded monostable switching circuits, to synchronize the signal with the spectrum signals, before the signal is applied to a data processing unit EDV. The data processing unit controls the sampling switch S so that each spectrum channel is sampled one per pitch pulse. The resulting samples are fed via an analogue digital converter to the data processing system EDV for storage and subsequent transmission. The fundamental frequency signal is also digitized in the data processing unit by a counter.
