Filed: 1968-11-04
Abstract: 1,243,790. Wrapping in inflated bags. A. C. FORMO. 11 Nov., 1968, No. 53352/68. Heading B8C. A machine for placing articles in bags uses an air jet to distend the bag initially and a bag spreader which moves into the mouth of the bag and has jaws which fully open the bag mouth for insertion of the article. Bag opening device.-The bags 117, which have a large lower flap adjacent the opening are supplied in a stack mounted on table 120 and held in place by a wicket 125. The table is biased upwards by springs 124 and is supported by a screw jack (not shown). The lower flaps of the bags are supported under the outlet of a low pressure air supply 68 and adjacent this outlet is the end of a high pressure air supply tube 74. A blast of air from tube 74 initially opens the bag, and it is opened further by the low pressure air supply. The bag mouth spreader comprises a pair of jaws 104 mounted on arms 103 pivoted at 101. The whole assembly is mounted on a carriage 92 which is reciprocated into and away from the bag by a piston 98 and cylinder 97. To open the mouth of the bag fully, carriage 92 is advanced so that the jaws 104 are with the bag and the jaws are pivoted upwards by the action of cylinder 105 to engage the upper part of the bag mouth. Article supply.-The articles to be packaged are fed singly to table 60. A chain 48 running over chain wheels 19, 20 carries pushers 50 which engage with the article and push it into the bag and, by continued pressure separate the filled bag from the wicket 125 and deposit it at removal position 182. The presence of the article is detected by lever 142 which operates switch 140 to set the bag opening mechanism in motion. When the article is a sliced loaf as shown, fingers 180 may be provided to prevent the front slices from toppling over.

Abstract: 1488719 Pocket inhalers CIBA-GEIGY AG 24 Dec 1974 [26 Dec 1973] 55674/74 Heading A5T [Also in Division B2] A pocket inhaler for spraying liquid or powder comprises an air compressing piston pump 12, and a cartridge 10 for liquid or powder having an inlet at its base mounted on a hollow stem 11 projecting from the pump cylinder 13 and a discharge orifice in its upper end, entry of air into the cartridge from the pump being prevented by an obturator positioned across a compressed air outlet of the pump until a predetermined pressure is attained when the pump piston 14 nears the end of a compression stroke. The obturator may comprise an elastic resilient diaphragm 21 having a slit 25, which slit opens at said predetermined pressure to allow compressed air to flow through the cartridge and expel the liquid or powder therein as a spray. A spring 18 returns the piston to its position remote from the diaphragm. The inhaler may be recharged by loading a new cartridge on the pump stem. In a modification, Fig. 5 (not shown), the slit diaphragm is replaced by a diaphragm (43) having an aperture (45) in which a plug (42) is movable. The plug normally closes the aperture but on pushing the piston inwards, an abutment (40) on the piston face is operable to displace the plug from the aperture to allow the flow of compressed air therethrough. Alternatively, the cartridge (110) Fig. 4, (not shown), and the pump may be formed integrally and disposed of after a single use, in which case no spring is required. The obturator is then provided by a diaphragm (33) which is ruptured by a perforator member (36) carried on the piston face, towards the end of the compression stroke. In each embodiment, a cap is provided to fit over the discharge end of the cartridge prior to use. The main parts of the inhaler, except the spring, may be moulded from thermoplastic material.

Title: Method and device for photoelectrically scanning an object by  means of an  optical beam
IPC: G01B11/02
Filed: 1970-11-24
Abstract: 1327065 Photo-electric scanning apparatus EXATEST MESSTECHNIK GmbH 24 Nov 1970 [27 Nov 1969 2 April 1970] 55816/70 Heading G1A Photo-electric scanning apparatus for determining the position of an edge defined by a transition from non-illumination to illumination at an unknown level utilises the principle of scanning the edge with an auxiliary beam prior to the main scanning beam in order to generate a signal representative of the full unknown illumination which signal is stored and providing a pulse indicative of the edge position as determined by the main scanning beam at the instant that the detector output attains a particular  fraction of the stored auxiliary signal above this stored value. The edge may be that of a radiating body e.g. a glowing wire, or of an object illuminated from behind. Thus, when the position of the other edge represented by a transition from illumination to non-illumination is also determined, the width of the body may be measured. In Fig.1, an object 10, e.g. sheet metal, is illuminated by source 12, and its edges imaged by lens 14 in the plane of detector 16. Rotating polygonal mirror 20 scans reflected radiation across slits 18, 19 which define the auxiliary and main beams X, Y respectively. The output of detector 16 is thus a combination of the light intensities reaching it via apertures 18, 19. During scanning of edge 10", the auxiliary beam scans the edge before the main beam and the output waveform of the detector includes a step portion A defined only by the effect of the main beam. When the output has reached half this value as detected in circuit 24, a timing pulse indicative of edge 10" is generated. During scanning of edge 10', the auxiliary beam scans the edge first and provides in step B in the detector output waveform a value of the illumination representative of that outside the edge 10', so as to provide a reference against which the output due to the main beam may be compared. Thus when the detector output reaches 1-5 times the step B, the other edge timing pulse is produced. The circuit 24 includes a differentiator 30, inverter 32, pulse weight discriminator circuit 34, delay circuit 36 and sample-hold circuit 38. Circuit 38 is present essentially to hold and pass on the levels A and B of Fig.2, towards coincidence detectors 46, 48, after amplification at 40. The actual signals fed to 46 and 48 are 0-5A (provided via dividing circuit 42) and the detector output E to device 46 (this being to detect when the detector output reaches the half value of A); and 2/3E (provided by passing detector output through divider circuit 44) and B (this being to detect when the detector output reaches 1À5 times the step B) to device 48. If desired, timing pulses for the main beam itself as provided by the arrangement of Fig.3; need not be used a less accurate measure of width would be determined by use of the time between steps A and B.
