Title: A folding duct for wrapping machines for goods in piece form
IPC: B65B49/02
Filed: 1961-12-13
Abstract: 950,372. Packaging. G. HAIN. Dec. 13, 1961 [Dec. 16, 1960], No. 44624/61. Heading B8C. A wrapping device consists of a ring of folding segments spaced apart to form gaps between them, the lengths of the segments being adjustable to alter the size of the ring without altering the width of the gaps. The adjustments may be made by hand, by means of a senser system (not described) which senses the articles, or automatically on movement of the articles into the folding aperture, transitional guide surfaces preceding the latter if necessary. In one embodiment a ring 14 has three fixed segments 2 and 7 mounted on it and three segments 3 and 6 mounted on an adjustable slide bar 18. The segments 6 and 7 have connecting pieces 8 which are fixed to the segments 7 and overlap the segments 6 so that as these segments move apart they still act as a single segment. In another embodiment (Fig. 4) all the segments are movable. Reciprocation of a rod 60 moves by way of a connecting-rod 68 segments 70, 71 and by way of rods 75, 78 segments 81, 82. The rods 60 and 75 are interconnected by a pinion gear 66 so that the pairs of segments 70, 71 and 81, 82 are moved in equal and opposite directions. The rod 61 is similarly connected to the remaining segments. In a further embodiment (Fig. 5) operation of an adjustment lever 102 causes an arm 103 of the lever to slide a sleeve 104 along a rod 105 to move segments 90, 91, 92 and 95 inwardly, and an arm 106 of the lever to move a slide 108 in the direction indicated by the arrow to move an extension segment 96 below a segment 94. Various other embodiments are also described. The segments may be metal, plastics, rubber, rubber coated with bristles or may be made of flexible wire cloth.

Abstract: 1,099,488. Tapping gas cartridges. SOCIETE INDUSTRIELLE POUR LA DIFFUSION D'EQUIPEMENT ET DE MATERIEL " SIDEMAT." Oct. 25, 1965 [Oct. 24, 1964], No. 45131/65. Heading B8T. A device for opening and resealing gas cartridges comprises a valve head 13 locked by a pin 17 to a base 5, the valve head having a needle 14 which may be screwed inwardly and outwardly, a first clamping arm 1 attached to one side of the base and connected to a second clamping arm 2 having a transverse portion at its free end which engages a groove 9 in the opposite side of the base. The valve head 13 is initially unscrewed to its fullest extent and then the base is placed on the cartridge 4 with a sealing ring 19 engaging the top 4b of the cartridge. The clamping arms 1, 2 are then folded around the cartridge and a clip 11 pivoted by a pin 10 pulls the transverse portion of the arm 2 into the groove 9 by a camming action. Wing portions of the clip 11 pass either side of the cylindrical body of the valve head and are locked in position by a skirt 12 when the valve head is screwed down, thereby causing the needle 14 to pierce the top 4b of the cartridge. The relative positions of the skirt 12, needle 14 and the length of the clip 11 are so determined that the device cannot be initially clamped on to the cartridge if the needle 14 projects below the lower face of the base 5. Vents in a sleeve 15 and in the base 5 align on unscrewing the valve head 13 to give an indication of any residual gas left in the cartridge before the device is completely removed.

A metallic skid rail 2, for use in a pusher furnace, is loosely mounted on an insulated watercooled bearer tube 1. Lateral lugs 3 welded to the tube 1 prevent lateral displacement of the skid rail 2, whilst dogs 4 welded across the top of the tube 1 and passing through recesses in the skid rail, prevent its longitudinal displacement. The skid rail may be of inverted channel section, with limbs 10 straddling a guide rib 7 welded to the tube 1. Loose fitting cottered bolts 9, secured to further lugs welded to the tube 1, and extending through bores in the limbs of the skid rail, prevent the rail from being lifted off from the tube 1. The rail may be formed with dovetailed recesses (not shown) in its base so that it rests on the tube 1 through a plurality of feet, and not over its whole length. The skid rail may be of a one or a two part construction. In the latter case, Fig. 4, the skid rail parts 2a, 2b are formed with complementary castellations to prevent their relative displacement. Dependent lugs 12 on the parts 2a straddle the parts 2b and are secured thereto by bolts 13. Ribs 15 may be formed on the rail to extend out over the adjacent refractory insulation 11.

The stations 23, 33, 43 also have storage zones 21, 31, 41 controlled by manually operated locking systems 22, 32, 42. An electrically controlled indexer 5 so operates a contact on each carriage that, depending on its position, a control circuit of a relay 27 or 37 controlling points 28, 38 is closed or neither is closed when a carriage is destined for line 40. The control system comprising circuits 100, 200, 300, 400 is controlled by buttons 211, 311, 411. In operation, with empty carriage locked at 15, it is loaded and if destined to line 20, for example, the button 211 is pressed; the circuit 200 then causes: (a) the exit 25 to release an empty carriage from zone 24; (b) the loaded carriage is only then released from 15; (c) a signal for line 20 and storage 21 is transmitted to indexer 5 which sets the carriage contact so that relay 27 is energized. Electronic and electromagnetic forms of the control circuits are disclosed.

Title: Improvements in safety devices in the air intake of combustion installations operating with pulsating combustion
IPC: F23N5/24
Filed: 1965-11-09
Abstract: 1,107,025. Pulsating type combustion apparatus; ignition systems; centrifugal blowers. JUNKERS & CO. G.m.b.H. Nov. 9, 1965 [Nov. 14, 1964], No.47387/65. Headings F1B, F1C and F1L. [Also in Division F2] A safety device in the air intake system of a pulsating type combustion apparatus having an electrically driven combustion air blower arranged in a housing, comprises a non-return valve freely mounted about the drive shaft of the blower for axial movement towards the blower in the opening direction under the action of combustion air suction. The combustion apparatus comprises a combustion chamber 10 having an intake pipe 11 with a silencer 17 and a resonance tube 12 leading into an exhaust silencer 13. To start the apparatus a valve (not shown) in the fuel gas supply pipe 22 is opened. The gas supply pressure is communicated by a tapping 23 to one side 18a of a diaphragm 20 resulting in displacement of the diaphragm which causes a mercury switch 26 to complete electric circuits 27, 28 for the combustion air supply system 30 and an ignition device 31 respectively. An electric motor (34), Fig. 2 (not shown), thus starts to drive the centrifugal blower (44) of the air supply system 30 so as to feed combustion air through duct 47 to the intake silencer 17 and past a non-return valve 15 into the combustion chamber intake pipe 11. The air pressure build up is communicated by tapping 25 to the side 19b of a second diaphragm 21, the displacement of which opens a valve 24' allowing fuel gas to pass from pipe 22 through pipe 22' and past a non-return valve 16 to the intake pipe 11. Combustion having been initiated by sparks at device 31, diaphragm 20 is displaced by the pressure rise in pipe 11 communicated by tapping 32 and switch 26 thus breaks circuits 27, 28 to cut out the blower motor (34) and ignition device 31. The intake (46) to the blower (44) is closed when the combustion apparatus is not operating by a dished non-return valve member (48) which slides axially on an extension (35b) of the blower driving shaft of the electric motor (34). During combustion chamber operation the valve member (48) is held open by the passage of combustion air therepast. Wings or vanes (50) on the member (48) cause the air to exert a torque on the member in the direction of rotation of the blower (44), so as to prevent chattering during opening. The other end (35a) of the electric motor shaft carries an eccentric sleeve (37) which acts on the contact breaker assembly (38) of the ignition circuit so as to make and break the circuit once for every revolution of the motor. A coil (41), capacitors (42) and resistors (43) are also mounted in a compartment (36) surrounding the contact breaker assembly.
