Title: Improvements in or relating to electroplating barrels
IPC: C25D17/20
Filed: 1965-04-20
Abstract: <PICT:1030589/C6-C7/1> <PICT:1030589/C6-C7/2> A plating barrel is formed of a number of perforated plates mounted at their ends on polygonal end members, one plate forming a charging door which is slidable in the direction of the axis of the barrel, and is held by a pair of resilient metal strips acting as guides secured to the edges of adjacent fixed states.  The perforated plates may be of polypropylene, and the metal strips are of titanium, or alloys resistant to the electrolyte. The barrel is constructed of 6 plates of metal or plating 40...45 Fig. 5, mounted on end plates to form a hexagonal container, and is rotatable through gearing and electric motor.  The panel 45 acts as a sliding lid held by spring slide guides 56A, 56B, the lid having a handle 62, and engaging a claw catch, in the closed position.  At the other end of the sliding lid a pair of spring pressed detents enter notches made in the frame member.  A pair of perforated slant panels 59 are mounted inside the barrel and act as a shoot when discharging the load downwards.  The slant panels also act as agitators during rotation of the barrel. This may also be cylindrical instead of polygonal, and rotated in a vertical or an inclined axis.  A series of these plating barrels may be mounted on a overhead trackway of oval lay-out, with stations for chemical cleaning, plating, rinsing, and drying. The barrel is suspended from a trolley 13, Fig. 1, mounted on a cantilever beam extruding outwardly from a trackway 12 and carried on wheels mounted each side of the trackway.  This is segmented whereby when the barrel moves over a station, it is lowered together with the segment of the track, which is followed up by a replacement segment from above, leaving a continuous track allowing other barrels to move forward while the first is rotated in the station.  The barrel carriages are moved from station to station by pusher fingers 19 operated by hydraulic device 21.

Abstract: 894,657. Sewing-machines. SINGER MANUFACTURING CO. May 15, 1959 [May 26, 1958], No. 16711/59. Class 112. Thread end holders, using the movement of air. A thread end holder for securing the loose ends of the sewing threads during the initial operation of the stitching mechanism of a sewing-machine comprises a rod 27 carried on the machine head 5 for endwise movement thereon, a clamping foot 41 mounted on the rod for movement into and out of engagement with the work supporting surface of the machine, and fluid pressure means for imparting endwise movement to the rod. The rod 27 which comprises two parts 26 and 29 is mounted for endwise sliding in a bushing 28 in the head of a cylinder 20 and in a bracket 30 mounted on a plate 17 secured to the head 5. A piston 25 within the cylinder is mounted on the part 26 of the rod and biased upwards by a spring 36. An arm 34 mounted on a collar 33 on the piston rod projects through a slot 35 in the plate to restrain the rod from turning. Compressed air is supplied to the top of the cylinder from a solenoid actuated valve unit 38. The thread clamping foot 41 has a horizontal stud mounted in a bore in a shank 43 secured to the lower part 29 of the rod 27, the foot 41 being free to turn about the horizontal axis of the stud to provide automatic levelling relative to the throat plate 12. The turning of the foot is limited by a pin mounted on the stud, which is received in a groove in the shank, (Fig. 4, not shown). To position the thread ends beneath the clamping foot a blower is provided comprising a bore or nozzle 50 in the throat plate positioned to blow the threads beneath the foot in a direction slightly forward of the direction of feed and connected to a source of compressed air. Before the operation of the sewing machine is commenced the thread ends are blown under the foot, the solenoid of the valve unit 38 is energized to supply air to above the piston and-the foot is forced downwards to clamp the thread ends against a roughened surface of the throat plate. After the formation of a few stitches the solenoid is de-energized and the spring 36 raises the piston and the clamping foot. Releasing thread tension. To prevent breakage of the needle thread while clamped by the foot when there is insufficient thread in the thread system to accommodate the take-up action an arm 53 pivoted to a bracket 54 has one end engaged by the collar 33 on the piston rod when the clamping foot is lowered. The other end of the arm 53, which extends round the head 5, then engages and releases the needle thread tension device. The presser foot has a sole plate 15<SP>1</SP> mounted for rotation about an axis coinciding with the axis of a needle aperture in the foot, so that the plate 15<SP>1</SP> will remain in line with or tangential to the line of seam formation as the work is moved in straight lines or around corners respectively. The throat plate has a needle aperture 13 and is provided with a roughened surface in the area engaged by the foot 41.

IPC: B21D39/16
Filed: 1953-06-17
Abstract: 741,006. Tube expanders; machine-tool details. CRANE PACKING CO. June 17, 1953, No. 16778/53. Classes 83 (3) and 83 (4). Speed-responsive electric control means for cutting off the power to a motor-driven shaft when its speed is reduced to a predetermined level by the torque-load thereon includes an electric generator driven from the shaft, " offon " means for controlling the delivery of power to the motor, a switch for controlling said " off-on " means, the switch being held in the " on " position as long as the current from the generator exceeds a predetermined level, and manually-operated means for holding the switch in the " on " position independently of the action of the generator. A tube-expander 18 is rotated by a compressed-air motor 10 supplied through a pipe 64 controlled by a valve 74. The valve 74 is held open, against a spring 78, by a solenoid 84 in a circuit 114, when the circuit is closed by a switch 116. The switch 116 is opened, against a spring 123, by a relay 110 in a circuit 106 when the circuit is closed by a switch 98. The switch 98 is held open by a relay 96 to which current is delivered by a generator 28 driven from the shaft of the tube-expander. When a tube has been expanded sufficiently and the load causes the expander to rotate more slowly, the generator 28 will not provide sufficient current to hold the switch 98 open against a spring 104, the resulting closure of the switch 98 causing the valve 74 to close to cut off the air supply to the motor. Independently of the generator the switch 98 is also controlled by a push-button switch 44 in the handle 12 of the tool. When the push-button is not depressed a circuit to an electromagnet 124 is closed to hold the switch 98 open, and when the button is depressed, e.g. by gripping the handle 12, the electromagnet 124 is de-energized and the switch 98 is then under the control of the generator-operated relay 96. In a modified system, Fig. 3 (not shown), the switch 116 is operated directly by the relay 96. A throttle 14 is provided in the air supply line.

Title: Apparatus for the underwater massage treatment of a patient
IPC: A61H33/02
Filed: 1974-04-17
Abstract: 1461618 Underwater massage apparatus K GABMEIER 17 April 1974 [17 April 1973] 16822/74 Heading A4N [Also in Divisions A5-6] Apparatus for massage treatment of a patient partially immersed in bath liquid, comprises a bath tub 1 for containing the bath liquid, which may be an iodine or sulphur bath, a carrier frame 2 freely movable into and out of the bath tub, a flexible mesh support 8 for the patient mounted on the carrier frame, a plurality of nozzles 17, for producing jets of liquid, selectively mounted in openings in a carrier mat 31 suspended from the support by carriers 18', the nozzles being spaced from each other and the jets of liquid impinging on the patient through the openings in the support. The carrier frame, support and nozzles constitute an immersible unit for free movement into and out of the bath tub. A pump (27), Fig. 10 (not shown) accepts bath liquid from the bath tube via an intake pipe 26 and circulates the liquid to the nozzles via control valves (23) and hoses 21, 22, the pump (27) being fixedly mounted outside the bath tub. Groups of the nozzles 17 may be arranged for massage treatment of separate parts of the body, each group of nozzles being fed from a control valve (23) via a main 20. The support 8 is subdivided into elongated portions, each portion corresponding to a body part of the patient and the portions forming an integral support surface. The carrier frame 2 comprises elongated beams, two pairs of carrier elements 4 being pivoted at 3 to and inside the beams, the arrangement being such that the carrier elements 4 each support an elongated support portion for angular adjustment of the support portions relative to one another. Hangers 6 carrying cross-bars 7 are pivotally attached at 5 to the ends of the carrier elements 4. The longitudinal edges of the support 8 are detachably mounted to the hangers 6 by means of rings (30), Fig. 9 (not shown) and guides (28) attached to the hangers, the support 8 being held under transverse tension. An adjustable foot rest 9 may be provided on the hanger 6 adjacent one end of the carrier frame. A source (36) of gas, e.g. oxygen or air, may be supplied to the pump (27) via a check-valve (34) to provide an aerated liquid flow to the nozzles 17. Each main 20 is located adjacent a cross-bar 7.

Title: Construction of artificial dentures
IPC: A61C13/14
Filed: 1959-05-19
Abstract: 911,549. Dental flasks. SMITH, C. C. May 19, 1959, No. 16901/59. Class 87(2) A dental flask 18 comprises two sections 16 and 28, the lower 16 of which contains a lower mould section 14 and a positive cast 12 of the user's mouth while the upper 28 contains an upper mould section 26 of porous material in which the teeth 24 are embedded. The cast 12, mould section 26 and the opposed peripheral edges of the flask sections are preferably coated with an alginate separating medium to facilitate removal of the completed denture and then section 26 is packed with a polymeric, e.g. acrylic resin, denture base material 38, after which the flask and mould sections are assembled and compressed between the pressure head 62 and base platen 46 of a press. A second flask 72 may also be compressed at the same time, being placed between the head 62 and the flask 18. The material 38 distributes evenly over the cast 12 and flashes outwardly between the edges of the mould sections 14, 26 and the flask sections 16, 28. The latter are provided with opposed annular grooves 40, 42 to receive the flask, this not only presenting a positive seal but also holding the material 38 in place against radial inward slippage that would otherwise occur during shrinkage as a result of polymerisation. A manifold 74 interposed between the flasks 18, 72 has a central port 78 surrounding the opening 36 in the cover 30 of flask section 28. Water is forced into the flasks 18, 72 through the inlet 122 and maintained under pressure while the material 38 is heated by elements within the pressure head 62 and platen 46. The water penetrates the porous mould section 26 and presses the material 38 tightly against the cast 12 during its polymerisation, thus preventing shrinkage and consequent pulling away from the pattern 12 with a consequent misfit. Where only a partial denture is to be made, the cast 12 and section 14 must be made impermeable to the flow of water, this not being necessary where the material 38 forms a complete seal as in the embodiment described above. Cooling should be carried out slowly after the polymerisation is completed, for example by means of passages in the manifold 74, through which a coolant is passed. The mould section 26 and the completed denture are removed from the flask section 28, and the mould section 14 and cast 12 from the flask section 16, by means of a frustoconical knockout tool 34 attached to the pressure head 62 as shown in Figs. 10, 11, the flask sections being supported on pins 124 upstanding from the platen 46.

Title: Lamp bulb orienting apparatus
IPC: B23Q7/04
Filed: 1963-04-30
Abstract: 961,010. Endless conveyers. SYLVANIA ELECTRIC PRODUCTS Inc. April 30, 1963 [April 30, 1962], No. 17008/63. Heading B8A. Lamp bulbs 1 of a kind which have a skirt diameter equal to or greater than the maximum bulb diameter are fed from disorderly assemblage in a hopper 12, are vertically oriented on a conveyer at 34, and are delivered to a shoot 36 which feeds a lamp sealing machine (not shown). An endless chain conveyer 14 has supports 18, 19 which lift one or a pair of bulbs from the heap in the hopper 12. The conveyer load is trimmed by a member 13. An air jet 21 (Fig. 2) forces the bulb or bulbs against the upstanding portion 19 of the conveyer support. This results in the bulb or bulbs being in axial alignment with two pairs of rods 72, 74, each pair projecting from a respective bulb orienting head 64. The latter are carried on both sides of the conveyer 14 by respective endless chain conveyers 54, both of which are driven in synchronism with the conveyer 14. The rods 72, 74 are spring loaded away from the conveyer 14 but as the conveyers progress, a tail portion of each rod 72 engages a cam member 84 and thereby the two pairs of rods 72, 74 are driven inwardly to cause rubber tips 78 carried by the ends of the rods, to engage the bulbs. One tip 78 engages the exterior of a bulb while the tip on the corresponding rod carried by the conveyer chain 54 on the opposite side of the conveyer chain 14 is driven into engagement with the interior of the bulb. Thus whichever way round the bulb happens to lie on the respective support 18 of the conveyer 14 it will have its interior engaged by a rod 72 or 74 carried by one or other of the two conveyers 54. The tail portion of each rod 72 passes from the cam member 84 to cam member 94 (Fig. 5, not shown) of helical profile, thereby causing the bulb orienting heads 64 and associated rods 72, 74 to be turned from the horizontal to a vertical orientation. The now vertically disposed bulbs are delivered to the shoot 36 (Fig. 2). A cam 98a allows a progressive retraction of the rods 72, 74 at the moment of transfer. The bulb orienting heads 64 are brought back to, and maintained horizontal by cams 94a and 88a associated with the return flight of the conveyer.
