Title: Apparatus for stripping a garment such as a glove from a garment supporting form
IPC: A41D19/04
Filed: 1958-01-23
Abstract: 839,916. Making gloves etc.; turning inside out. BEASLEY, M. M. Jan. 23, 1958, No. 2289/58. Classes 112 and 141 In a glove-finishing machine the glove is stripped from a heating form 12 by coacting rollers 73, 74 which are rotatable in opposite directions on opposite sides of the form and are movable as a unit toward and away from the form. The machine comprises a set of hollow forms, 11, Fig. 1, and a set of electrically heated forms 12, the two sets being rotatable intermittently in out-of-phase relationship and in opposite directions in the same vertical plane. A glove is mounted in insideout condition on the uppermost form 11 and when this form reaches the lowest station plungers 42, 43 tuck the ends of the fingers and thumb into the respective parts of the hollow form where they are held by spring clamps. At the next station clamps 51, 52 engage the cuff part and draw the glove from the form 11 on to the adjacent heating form 12 while turning it right-side-out. The clamps are mounted on a horizontal slide 54 provided at its lower edge with a rack 63 driven by gear 64, the slide being given a reciprocating horizontal motion. Actuation of the clamps 51, 52 is effected by a cam roller 60 engaging the cam 56. The heating forms 12 are rotated until the glove reaches the stripping station where it is engaged by rollers 73, 74 which are yieldably connected together by springs 86 and driven by belt 87 and drive roller 88. The rollers are mounted on one end of a frame 75 which is pivoted at its other end to the main frame 10 and is arranged to oscillate vertically so that its upward stroke occurs while the form 12 is stationary and its downward stroke occurs while the form is being rotated to its next station. After stripping, the glove is pressed by the rollers 73, 74 and conveyed on the belt 87 through the back wall of the frame 10.

Title: Improvements in continuously operating degassing equipment
IPC: B01D19/00
Filed: 1962-06-20
Abstract: 1,019,083. Degassing liquids; evaporators, film-type. AUTOMATIC PROCESS CONTROL Inc. June 20, 1962 [June 21, 1961], No. 23802/62. Headings BIB and B1M. [Also in Division G3] In an apparatus for degassing a liquid in which the liquid flows as a thin film over a heated surface under the action of a vacuum, the input of liquid to a reservoir supplying the thin film is controlled and the degassed liquid is fed to a utilization station ; by-pass means are provided to recycle to the reservoir degassed liquids in excess of the utilization station requirements. As shown in Fig. 1, fed liquid enters the outer glass cylinder 4 from a feed tank 25 via line 25, and diaphragm valve 22. The liquid rises up the annular space between the outer cylinder 4 and an inner aluminium cylinder 11 until it overflows at the top of cylinder 11 and descends as a thin uniform film where it is exposed to heat from the helical heating strips 15 surrounding the aluminium cylinder and to vacuum induced by a vacuum pump (not shown). Degassed liquid is pumped from the bottom of the inner container 11 by a helical pump 9 and out through pipe 10 to the utilization station. In the event of the demand for the degassed liquid diminishing or ceasing, the pressure of the liquid in line 10 builds up whereby diaphragm by-pass valve 37 is operated allowing the liquid to return to the reservoir through line 38. The feed to the apparatus is also controlled automatically to maintain a constant height of degassed liquid in the cylinder 11 and an automatic alarm indicates when feed reservoir 24 is empty. The temperature of the liquid in the cylinder 11 is sensed by a helical coil of wire 18 on the outer surface of the cylinder 11. A capacity probe 44 is placed in the inner vessel 11 and electrically connected to the diaphragm feed valve 22 so as to allow liquid to flow from the feed tank into the reservoir should the liquid level fall and to cut off feed should the liquid level rise for example, as a result of degassed liquid, not required at the utilization station, being recycled through diaphragm valve 36 and line 38 to the bottom of the reservoir.

Title: Improvements in or relating to filmstrip transport mechanisms for projectors
IPC: G03B1/38
Filed: 1960-01-25
Abstract: 905,636. Strip - film feed mechanisms. YOUNG, W. April 18, 1961 [Jan. 25, 1960], No. 2590/60. Class 97 (1). For prolonged projection of single frames, strip-film feed mechanism comprises a rotatable drum carrying at least one pin for engaging a film-feed sprocket-wheel and imparting to it at each engagement a rotation corresponding to one film frame, and control means for retracting the pins. As shown in Figs. 1 and 2, pins 8 and 9 carried on a continuously-rotated drum 4 can engage slotted wheel 16 fast with sprocket-wheel 3 when in the operative position (pin 9, Fig. 1) into which the pins are urged by springs 10 and 11. As a projecting pin passes a wedge-shaped member 18 it is pressed back into a retracted position and held by an arm of spring 14 engaging a groove 12 on the pin. A pin is released by operation of a switch to energize magnet 21, whereby an arm 19 of armature 20 engages and displaces the first arm of spring 14 to pass it. Just before pin 9 enters a slot of wheel 16 it deflects a pivoted sector 15 so that a locking pin 17 carried by the sector leaves a slot. As pin 9 leaves the slot after rotating wheel 16 and sprocket 3 to move the film by one frame, locking-pin 17 drops back into a slot. Initial movement of the armature 20 when the control switch of the electromagnet 21 is closed establishes a circuit via contacts 24 on a resilient arm 25 of the armature and on pin 17. The magnet will therefore remain energized until pin 9 is released and sector 15 pivoted to break the contacts 24. Two drum and pin arrangements may be provided at either side of the sprocket-wheel and adapted to produce opposite rotation thereof. A film bearing two rows of images in opposite sequence may be used with an adjustable film gate to mask either row. Instead of being spring-driven, the pins may be electromagnetically urged into the operative position.

Title: Improvements in and relating to apparatus for the automatic adjustment of the clearance of brake-shoes
Inventor: NAHODIL ANTONIN
IPC: F16D65/54
Filed: 1955-01-31
Abstract: 765,823. Automatic adjustment devices for brakes. ZAPADOCESKE AUTODRUZSTVO. Jan. 31, 1955, No. 2849/55. Class 103 (1). In an automatic adjustment mechanism for adjusting the clearance of brake shoes, the adjusting means, retained by friction, are mounted in the wheel brake cylinder and are adapted to be engaged by a shoulder on working pistons in such a way that movement in an axial direction through a distance equal to the clearance necessary for the disengagement of the brake shoes from the brake drum is possible between the working pistons and the frictional adjusting means, the latter being capable of being displaced solely by the force produced by the pressure of liquid during the braking operation. In the embodiment illustrated the invention is applied to an internal shoe drum brake, the working pistons 4 of the wheel brake cylinder 1 are each provided with a projection 6 over which a split friction ring 7 is fitted and on which is screwed a cylindrical nut 9 having a flange or head 10. The split friction ring 7 has a slightly larger diameter than the bore of the cylinder 1 such that it is provided with frictional resistance in the bore. In the operative position of the brake illustrated in Fig. 1, the working pistons 4 are forced apart by hydraulic pressure supplied via aperture 2 from the master cylinder, and the flange 10 of the cylindrical nut 9 secured to the piston 4 abuts the recessed portion of the friction ring 7 to move the friction ring if necessary to accommodate any wear of the friction linings. During this braking operation, a clearance 16 is present at the outer side of the rings 7 and it is this clearance which determines the size of the clearance between the friction linings and the brake drum. The force required for the displacement of the rings 7 must be somewhat greater than the retraction force of the spring 18. Fig. 2 illustrates the position of the parts of the wheel brake cylinder when the brake shoes are released. Alternative constructions are described but not illustrated in the Specification, e.g. the friction ring 7 may be directly mounted in a groove in the piston. Specification 726,548 is referred to.
