Abstract: 958,017. Reciprocating conveyers. F. JAS. LAMB CO. Jan. 24, 1963 [Jan. 26, 1962], No. 3040/63. Heading B8A. A reciprocating conveyer for advancing workpieces A along a continuous pan runway 2 comprises a series of identical supports 19, each having a pivotally mounted brush member 25 which normally hangs downwardly. The brush supports 19 are connected to transfer rails 11 which are supported for longitudinal reciprocation by and between rollers 8, 10 mounted on rails 6. The brush supports which move in the curved portion 1c of the runway are also connected by diagonal braces 21 and this group of supports is connected by thrust rods 20a, 20b to the supports and transfer rails which move in the straight portions la, 1b of the runway.

Filed: 1916-03-01
Abstract: 104,223. Smith, C. E. March 1, 1916. Gilding.-Relates to machines for applying gold leaf to book covers &c. from a package roll. According to the invention, the pressure of the delivery roller on the work can be varied when desired, and the machine comprises a number of positively-driven rollers and pressure rollers for feeding the work, one or more holders for a package roll of gold leaf, and one or more rollers for applying the leaf.

Title: Hypodermic assembly
Inventor: JR GEORGE NORTON HEIN
IPC: A61M5/24
Filed: 1957-01-29
Abstract: 805,184. Hypodermic syringes. BECTON, DICKINSON & CO. Jan. 29, 1957, No. 3144/57. Class 81 (2). A hypodermic syringe comprises a casing which contains an ampoule closed at one end by a stopper and at the other end by a piston, the ampoule containing a hollow needle having an opening which is remote from the point and extends outside the ampoule beyond the piston, and means within the casing for projecting the needle through the stopper and piston so that the point extends from the ampoule and the opening is brought within the ampoule, whereafter the piston is moved to expel medicament through the needle. A transparent glass or plastic ampoule 27 having a rubber stopper 28 and a piston 29 is disposed in a polystyrene carrier 16. A hypodermic needle 30 is fixed in a plug 34 which is slidable in the rear of the carrier 16. The needle 30 extends through the ampoule piston 29, medicament in the ampoule 27 and the stopper 28, the needle point being located in a recess 31 in the stopper 28 and protected by a rubber layer 37 between the stopper 28 and a ring 36 which is fitted over the end of the carrier 16. An aperture 32 in the needle is located behind the piston 29. The carrier 16 is in the forward portion 11 of an aluminium outer easing. A spring 38 held compressed between arms 40 of a resilient metal mounting member is disposed in the rear portion 10 of the casing, the mounting member being held forwardly by a retaining sphere 48 so that portions 43 engage the bore of the casing and inwardly extending parts 41 of the mounting member prevent release of the spring 38. The sphere 48 is prevented from movement into a recess in the rear of the syringe by a safety-pin, the shaft 46 of which is gripped by narrow rear coils 45 of the spring 38. In use the safety-pin is removed and the syringe is pressed against the body so that carrier 16 moves rearwardly, thus pressing the spring mounting member rearwardly and moving the ball into the rear recess of the syringe. The portions 43 of the mounting member enter an enlargement 12 of the outer casing and spring apart so that the spring 38 is released. The spring 38 pushes forward the needle plug 34 and the needle 30, so that the aperture 32 enters the ampoule 27 and the needle 30 punctures the skin, and moves the piston 29 so that medicament is discharged from the ampoule 27 into the patient. In modifications, two springs arranged concentrically or in series may be used, one spring producing a sufficiently great thrust to dislodge the needle plug and the piston if they have slightly adhered during storage to the carrier or ampoule respectively. The ring 36 closing the forward end of the syringe may be replaced by a detachable cap and the carrier and ampoule may be made as a unit. A slot 63 (Fig. 10) may be provided in the ampoule stopper 60 through which is inserted a needle for filling the ampoule. The outer casing may be made in separable parts (not shown), the joints being covered by a sleeve of cellulose material.

Abstract: 582,478. Shaping wood by pressure ; bending wood. LYON, M. J., AGET, E., LOUCHARD, M., and GUILLOTEL, G. Feb. 1, 1946, No. 3217. [Classes 145 (i) and 145 (ii)] In the manufacture of angle-shaped members from thin sheets of plywood, or the like, the sheets are placed together so that the grain in each of them obliquely intersects the line of subsequent folding or bending, and the parts are joined by glue applied between overlapping marginal bevelled portions in each layer, the layers being arranged so that the grain in one layer intersects the grain in the next layer. As shown in Figs. 1 and 4, a straight angle member is formed from overlapping diamond-shaped layers cut as indicated in Fig. 1 with bevelled ends, and bending along the line 4-4 is effected by clamping the layers between jaws 5, bending at right angles by a sliding block T, and allowing the glue to set while under pressure of a further clamp 6. An annulus of U-section can be produced from blanks shaped as shown in Fig. 7, which are squeezed vertically between a pair of curved surfaces designed to shape the bottom of the U and then the flanges are shaped by a pair of slide blocks. A flanged ring as in Fig. 8 is formed by shaping in a die elements shaped as in Fig. 9. The shaping of the articles may be effected by a former and an air-pressed membrane by apparatus as described in Specification 579,048.

Abstract: 936,709. Fishing floats and lures. W. SEIGLE. Jan. 29, 1962, No. 3286/62. Class 48. [Also in Group XXV] A fishing line clamp for connecting a float or lure to a fishing line 21, Fig. 2, comprises a pair of split rings 22, 24 secured to or formed integrally on the periphery of the float or lure to provide an opening 30 for the fishing line, and a third split ring 32 rotatably mounted between the first two split rings 22, 24 and adapted to be manually rotated to clamp the line to the float. The split ring 32 is preferably circular in cross-section and has an end 36 which is outwardly bent to enable the ring to be grasped. The other end 34 is preferably arcuately curved outwardly to guide the ring over the line. A bowed portion 48, Fig. 7, of or a transverse groove in the split ring 32 forms an opening 50 which when positioned opposite the opening 30 enables the float to slide on the line 21. A stop which bridges and connects the respective ends 29, 27 of the pair of split rings 22, 24 may be provided to prevent rotative movement of the ring 32 by engagement with the end portion 36 when the clamp is disengaged. The ends of the split ring 32 may be formed into closed loops.

A slip-ring induction motor 1 is coupled to a second A.C. motor 3 which has at least one operating speed greater than that of the motor 1. A controller 6 may be set to apply alternating-current to the motor 1 and simultaneously to supply the motor 3 with directcurrent so that the second motor acts as a brake, the torque of which is variable according to the values of the applied voltage and rotor resistance, and creeping speeds are provided. For increased speed operation the motor 1 is operated from the A.C. supply in the usual manner, and, for speeds in excess of the operating speed of the motor 1, alternating-current is applied to the motor 3 and the motor 1 is switched off. The motor-shaft carries a pulley 5 and a brake 4 which becomes effective in the "off" position of the controller to prevent rotation of the motors by the load.
