Title: Apparatus, system and method for applying and shaping a prefabricated material to a form
IPC: B29C63/22
Filed: 1979-05-16
Abstract: Power-operated apparatus is provided for applying roof-top material such as vinyl, plastic, leather or the like, directly to an automobile roof or to a rooftop form. The apparatus includes a plurality of clamping brackets for respectively clamping a rooftop material blank at spaced-apart locations thereon while it is on the rooftop or form. Each clamping bracket is coupled to fluid-actuated cylinders, which are in turn coupled to fluid supply and control means for applying a pulling force on the clamping brackets and tensioning the rooftop material blank for seating it into the desired shape and position on the rooftop or form. All the clamping means are pulled simultaneously to maintain the forces on the rooftop material blank in equilibrium. If the rooftop material blank is applied directly to the vehicle roof, cement is first applied to the rear surface of the material blank and to the vehicle roof. If the rooftop material blank is being applied to a form, it is first coated with a thermosetting material and the form is preheated for activating the thermosetting material. The seated and shaped blank is held on the form until the thermosetting material has set so that the blank retains the desired shape. A system is also disclosed for mass production of preshaped rooftop material blanks, wherein several forms are mounted on a turntable-type conveyor for carrying them through several stations for heating the forms, applying and tensioning the material blanks, curing the thermosetting resin and removing and trimming the shaped material blank.

The arrangement is such that linear movement of piston 51 is translated into rotary movement of the operating shaft 14. <IMAGE>
Patent GB-795892-A (GB)
Abstract: 795,892. Valve closure members. NU-WAY HEATING PLANTS, Ltd. Aug. 15, 1956 [Aug. 15, 1955; Oct. 22, 1955], Nos. 23400/55 and 30258/55. Class 135. In a flow controlling valve wherein a control member with a cylindrical portion having a peripheral groove of varying cross-section is adjustable within a body part, the cylindrical portion is formed as two interengaging relatively adjustable parts which co-operate to form the groove and can be adjusted to alter the cross-sectional area of a portion of the groove. Fig. 1 shows cylindrical parts 8a, 8b end-to-end within a body part 5 having a radial inlet 6 and an axial outlet 7. The groove 9 is formed by the flat end face of one of the parts 8b as shown and a chamfer of gradually increasing depth on the other part 8a. A smaller chamfer 13 which can be brought to register with any part of the larger chamfer is formed on the part 8b. The parts 8a, 8b are carried by coaxial stems 11, 12 provided at their ends remote from the parts 8a, 8b with means for retaining them in any desired relative angular setting. The groove 9 opens into a radial passage 10 which itself communicates directly or via an annular chamber 15 and radial ports 16 with an axial passage 14. Fig. 3 shows a control member with two portions 18a, 18b axially slidable as a unit through a hole or bore formed in a body part 17. The outer part 18a has a longitudinal V-shaped slot 20 which with the periphery of the inner part 18b forms the groove of varying cross-section. The inner part 18b has a helical groove 21 and is angularly adjustable relative to the part 18a to vary the cross-sectional area of a portion of the groove formed by the slot 20. The single groove 21 may be replaced by a munber of grooves or depressions which may be spaced longitudinally and/or circumferentially. A selected groove or depression may be brought into register with a selected portion of the slot in the outer part by angular and/or longitudinal adjustment of the inner part 18b relative to the outer part 18a.

Title: Improvements in container destacking mechanisms
IPC: B65G59/10
Filed: 1980-01-30
Abstract: A destacking mechanism for a stack of thin-walled plastics containers, comprises cylindrical destacking wheels 6 rotatably mounted on a supporting frame 1, with their peripheries projecting at 7 into the destacking opening 2 in the frame so as to support the stack of containers. Each destacking wheel 6 has a helical groove 8 extending about its circumference for approximately one turn and opening into opposite ends of the wheel. The wheels 6 are rotatable in synchronism by a drive motor 14 connected to the wheel via a chain and sprocket drive, 11, 12, 17. Upon rotation of the wheels by the motor, the lip of the bottom container of the stack is engaged by the grooves 8 and the bottom container is fed downwardly and is destacked and discharged from the lower ends of the wheels. The mechanism provides for systematic destacking of large thin-walled plastics containers, such as eggboxes and trays. <IMAGE>

Title: Vehicle With Removable Load- carrying Body
IPC: B65D90/14
Filed: 1980-02-19
Abstract: The body (2) (e.g. a container on a trailer vehicle (1)) is removed from the trailer without the need for lifting gear by elevating one end of the body, e.g. using a hydraulic lifting ram (4), extending and locking pairs of legs (7 and 8) at the sides of the body, and lowering the one end of the body again so that the legs lift the body clear of the deck (5) of the trailer. The trailer can then be withdrawn. The tilting can be accomplished by tipping the trailer. The arrangement is simple to construct and operate, and offers a high degree of flexibility in the use of the body and the trailer. The legs (7 and 8) can be extended manually, since no great force is required, and simply locked by pins passed through them. <IMAGE>

Title: Indexing machine elements
IPC: D05C15/30
Filed: 1981-03-19
Abstract: A tufting machine has a needle bar which is longitudinally displaceable for purposes of pattern control, such displacement being effected with a mechanism comprising a cam/cam follower arrangement (1, 3). First and second actuators (11, 21) such as piston and cylinder assemblies, are connected respectively to the cam (1) and the cam follower (3) to control movement of the cam follower relative to the cam in opposite directions corresponding to opposite directions of longitudinal displacement of the needle bar (20). The first actuator (21) is reversible and the second actuator (11) operates to prevent and release the cam/cam follower movement between set limits corresponding to an indexed movement of the bar. The cam and cam follower may be defined respectively by a grooved shaft (1) and a roller (3) which engages and runs along the groove (4). In this case the first actuator may operate to rotate the shaft and the second actuator may operate to control movement of the roller along the shaft. <IMAGE>

Title: Inserting solder ring in pipe fitting
IPC: B23K1/20
Filed: 1981-03-28
Abstract: A solder ring (11) is loosely engaged in a recess (14) in the internal surface of a pipe fitting (10) and is then subjected to a rolling action which reduces the thickness of the ring and increases the diameter so that it is engaged firmly in the recess. An outer roll (25) is moved laterally into engagement with the outer wall of the fitting, and shifts the fitting towards the axis (19) of an inner roll (21) which had previously been inserted axially within the fitting. When two solder rings (11, 12) are present, they are squeezed between respective lands on the inner roll and their recesses (14, 15). This expands the rings into engagement with the recesses. <IMAGE>
Patent GB-2094470-A (GB)
Title: Examining surface profile
IPC: G01C7/06
Filed: 1981-05-15
Abstract: The method comprises the steps of directing an electromagnetic radiation, conveniently a laser beam 12a, against the surface 21 to be examined along a plane inclined to the surface and noting the profile of the termination of the radiation at said surface. The termination of the radiation may be viewed manually or recorded by a camera 29, preferably through a filter which gives a fine definition of the "line" of termination. For periodic examination of, for example a tunnel, the definition of the termination of the radiation is preferably converted to a digital form so that successive examinations can be compared. As in Fig. 5 beam 12a is rotated by mirror 13. There can be a second laser and rotating mirror, so that the surface is swept simultaneously by radiation in two planes intended to intersect at the surface. <IMAGE>
