Title: Rotational molding
Inventor: MEMERING LEROY J
IPC: B29C35/16
Filed: 1967-03-30
Abstract: 1,146,239. Cooling rotationally moulded articles. NATIONAL DISTILLERS & CHEMICAL CORP. 30 March, 1967 [26 May, 1966], No. 14617/67. Heading B5A. In a rotational moulding process yielding a hollow plastics article, the article is cooled by applying a cooling medium to the inside of the article at superatmospheric pressure and allowing the medium to escape to the atmosphere. As shown, the apparatus comprises a mould 28 fixed in a frame 25, 26, 27 which can be rotated about axes defined by rods 12 and 21. The mould has a removable lid 30 with a central hole into which may be fitted either a plug with a vent tube leading into the centre of the mould, or a cooling head 32 (as shown). The cooling head comprises inlets fed from supply 62 via hollow shaft 12 and flexible coupling 29, and outlet holes in its top plate. It is held in place by a toggle mechanism 33. The hollow plastics article is formed as normal and is then cooled, preferably while the mould is still rotating by passing the cooling medium through the spray head into the inside of the article at superatmospheric pressure; excess of the coolant escaping through the top plate of the spray head. The cooling medium may be nitrogen, steam, carbon dioxide, air, any gas inert to the plastics material or a fine water spray. The outside of the mould is preferably also cooled by spraying. The process may also be carried out in two stages, the heating and shaping being carried out using only a vent tube in the mould lid and the lid being replaced by a spray head before the cooling stage.

Title: Improvements in brakes
IPC: F16D65/14
Filed: 1931-05-18
Abstract: 378,542. Brakes. BENDIX BRAKE CO., 401, North Bendix Drive, South Bend, Indiana, U.S.A. May 18, 1931, No. 14625. Convention date, May 21, 1930. [Class 103 (i).] A servo-brake of the kind comprising a pair of linked floating shoes adapted to anchor at one end or the other according to the direction of rotation of the drum is applied by a floating lever disposed within the drum and having upstanding cam parts between the ends of the shoes. The shoes are preferably slightly flexible. The shoes 26, 27 connected by the adjusting screw 29 at one end are adapted to anchor at the other end against a pin 16 secured to the locking plate 15. The ends of the shoes are separated to apply the brake by a lever 18 slotted at 23 to receive the anchor 16 and having upturned end pieces 24 disposed between the shoe ends. An operating cable 19 is ,connected to the end 21 of the lever 18. A plate 34 on the anchor. 16 holds the shoes and lever laterally. In addition to the spring 33 connecting the shoes, there is a second spring 35 extending from the anchor 16 to the shoe 26. Thus when the lever 18 is operated with the drum rotating counterclockwise, the shoe 26 does not leave the anchor and with clockwise rotation, the end of the shoe 27 at first moves radially and outwardly until the shoe engages the drum, without however actually leaving the anchor and then returns to its initial position while the end of the shoe 26 leaves the anchor. The objectionable click due to the return of one of the shoe ends to the anchor is thus avoided. The shoes are held in position in relation to the drum by frictional engagement with spaced bearing surfaces formed on the back plate 15 effected by steady rests 28 comprising coil springs seated on the shoe webs with one end extending through the web and the back plate. The shoes are disengaged from the drum after an application by the " kick of the drum due to the distortion of the drum when the shoes are applied. As shown in Fig. 1, the web of the shoes decreases in height from the ends to the centre part to render them slightly flexible and in order that the flexibility may correspond to that of the drum, the height of the web at the centre part is approximately equal to that of the usual flange on the edge of the drum. Inclined parts 43, 44, Fig. 5, are formed on the back plate 15 for the cable 19 and its sheath 45, the sheath being secured by a plate 46.

Title: Improvements in and relating to cutting wheel teeth
IPC: B23F5/14
Filed: 1919-09-08
Abstract: 152,068. Sunderland, S. Sept. 8, 1919. Gear - cutting. - Generating-machines employing a rack cutter have a special indexing and quick-return motion for the tool when withdrawn from the blank, including a drum carrying mutilated wheels meshing alternately with a system of pinions. During the cutting period, the saddle 47 carrying the slide for the reciprocating cutter is fed downwards by the screw S, the blank WB being given a corresponding rotation through the worm gearing 43. The screw S is bevel-geared to a shaft 20 geared at 21 to a shaft 33 carrying an integral pinion 31 and gear 34 driving a gear loose on the shaft 40 through a ratchet clutch 37 provided with a detent 50. The shaft 40 drives the worm 43 through the change gearing shown during the cutting period, but is lccked by the detent during the quick return, thus effecting the indexing. The pinion 31 meshes with the segment 12 occupying half the periphery of the drum 11 loose on the shaft 20, the other half periphery being occupied by a segment 13 that drives the pinion 31 through an idler, thus reversing the shaft 33. The drum 11 is driven at a low speed during the cutting period by a gear 9 loose on the shaft 8 and driven through a ratchet clutch 5 from a constantly running worm-wheel 3. As soon as the segment 12 ceases to drive the pinion 31 and the segment 13 takes up the reverse drive a notched disk 39 permits a spring-controlled bell-crank to release a pawl 25 to drive a disk 7, keyed to the shaft 8, through one revolution from a rapidly running worm-wheel 24. Mitre wheels 27 gear the shaft 8 to an eccentric 28 connected at 46 to move the cutter saddle 47 into and out of mesh with the wheel blank. The mechanism is so timed that the cutter is rapidly withdrawn at the end of the generating traverse and rapidly returned at the end of the quick return, the throw of the eccentric being sufficient to provide time for this return, which is effected from the disk 7 by a ratchet clutch 15 that drives the gear 9 causing the clutch 5 to over-run. This motion is timed by means of a shroud 18 that trips the pawl of the clutch 15 at the required moment, the feed screw S being then driven at low speed again whilst the remainder of the single revolution of the disk 7 completes the throw of the eccentric to return fully the cutter slide to meshing position.

Abstract: 708,737. Valve limiting circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 12, 1952 [June 29, 1951], No. 15448/51. Class 40 (6) High frequency oscillations are applied to the grid-cathode circuit of a valve and similar oscillations of greater amplitude are rectified and applied as bias so that the output is more nearly constant. High frequency signals, such as occur in a F.M. receiver having a wide bandwidth are applied from valve 1 to the grid of valve 8 and to a tapping 4 on inductor 5. The signals of increased amplitude from the top of inductor 5 are rectified by diode 11 and applied as bias over inductor 13 to the grid of valve 8. Since the anode load 2 may be of very low resistance, the output amplitude from valve 1 is small and it is stated that the circuit requires smaller drive than the usual grid current limiter. In a modification, Fig. 3 (not shown), the connection to tap 4 is made at the top of the coil and capacitor 6 forms a potential divider with the grid-cathode capacity.
