Patent GB-1111148-A (GB)
Title: Improvements in or relating to the packaging of needles and the like
IPC: B65B15/04
Filed: 1965-09-10
Abstract: 1,111,148. Packaging needles etc.; shoots. P. H. FREZIN. 10 Sept., 1965 [11 Sept., 1964], No. 38824/65. Headings B8C and B8S. Needles, pins &c. are orientated, formed into a file and fed from the file between opposed adhesive tapes to form a belt with the needles arranged transversely to it. The needles, particularly comb needles for spinning apparatus, are fed from bulk by vibratory means and gravity through a series of shoots 13-17, the shoot 15 being apertured to permit dropping through of waste and having a slot 20 through which overlength needles cannot pass but other needles fall on to the shoot 16. The next shoot 17 is sloped to cause needles to descend head-first into a member 18 which distributes them into parallel sinusoidal channels 21 where they accumulate. The channels lead to a single channel 22, controlled by a rotary valve 23, feeding the needles between tapes 8, 9. An element 28 assists in retaining the transverse orientation of needles on the tape 9. The band is drawn off on to a reel (not shown). The tapes pass over levers (35), Fig. 3 (not shown), which act to stop the machine in the event of a breakage and photo-electric means 38 stops the tape feed if the supply of needles fails

Particulate material is continuously freeze dried by introducing large frozen particles thereof into a vacuum chamber, reducing the size and screening said particles to obtain particles of suitable size for drying and drying said suitably sized particles. In one embodiment the screening device 2 is placed above the drying beds 3. Particles of material enter the chamber, through an air lock, in a container 11. The particles are fed on to the first of a series of vibrating moving screens 2, of good thermal conductivity. Small particles drop through the screen on to the drying beds 3, where they are dried by conduction or radiant means and transported by vibration over a series of beds 3 to the exit air lock. The larger particles are moved along the screen 2 to a mill 21 which reduces the size of the particles and passes them on to the next screen. In a second embodiment (Fig. 2, not shown), the drying beds are placed alongside the moving screens and particles which fall through are transported to the top of the drying beds by a screw (5) which may itself be a drying bed. In a further embodiment (Fig. 3, not shown) each moving screen has an associated drying bed immediately below, each bed discharging into a common exit air lock.

A low pressure fluorescent discharge lamp has a vitreous envelope filled with rare gas and mercury vapour and having a major portion or portions of the outer surface of the envelope material unroughened and a minor portion or portions roughened and of such an area that the temperature and partial pressure of the mercury vapour adjacent the roughened portion or portions is reduced because of the increased heat dissipation from the roughened portion or portions. The roughened portions are produced chemically or abrasively as in frosting techniques and can amount to 0.5-4% of the total surface area of the envelope. The roughened portion of the envelope can be at the middle or at each end of the envelope and can be bandshaped. Additional means can be provided for reducing the vapour pressure of the mercury and can comprise cool chambers formed by shields between the electrodes and the ends of the envelope for condensation of the mercury, the outer surfaces of the cool chambers being at least partly roughened. Alternatively a knob-like extension can be formed on the envelope between the electrodes, the outer wall of the extension and/or the envelope surrounding the extension being roughened. The roughened portion or portions can be on the under surface or the side of the envelope or in two symmetrical positions and can be in the form of a letter, number, drawing or inscription for advertising. The filling can be 60 mg. of mercury and a mixture of argon and neon, containing 20% argon by volume, at a pressure of 2 mms.

[Classes 97 (i) and 98 (ii).] The process described in Specifications 356,701 and 364,559 of printing a lenticular film without lateral inversion by optical projection on to another lenticular film is modified by placing close to the negative gate N in the printing apparatus a lens K which projects a real image F2 of the colour-selecting filter F1, or of a diaphragm substituted therefor, or of a light-source of appropriate form such as that described in Specification 399,977, on to the optical system L3 by which the negative is projected on to the positive film P. The arrangement is derived from that shown in Fig. 1 of Specification 364,559 by placing the lens L3 of that Figure close to the negative N and shortening its focal length. The image F2 of the filter &c. should preferably be formed within the narrowest effective crosssection of the objective L3, which may be of double -symm etri - cal form, and which should preferably be of long focal length. A divergent lens D may be placed near the positive film P in order to form a virtual image F<1>2 of the filter at the same distance from the film P as the filter will be from the film P in the system used for subsequent projection.

In the absence of a signal input to reverse the condition of the tunnel diodes the capacitor will ensure that the diodes switch to the previous condition during each alternate half-cycle of the supply. In Fig. 2 (not shown) a matrix of such circuits is switched by coincidence of pulses on the a and b conductors. Non-destructive read-out is possible since pulses applied to the " write " wires find a diode 16 slightly below its threshold value.
