Title: Machine for molding carrying cases for bottles
IPC: B29C45/33
Filed: 1964-08-21
Abstract: 1,058,175. Injection moulding machines. GENERAL AMERICAN TRANSPORTATION CORPORATION. Aug. 21, 1964 [March 25, 1964], No; 34396/64. Heading B5A. An injection moulding machine comprises a movable platen 103, Fig. 1, carrying a male mould 200, and a stationary platen 102 carrying a female mould 300, and is particularly adapted to mould carrying cases. Fig. 2, whose side walls have ridges 32a, 33a and whose handles have lateral projections 51a, by having parts of the moulds movable normally with respect to the direction of movement of platen 103 to free the ridges 32a, 33a and projections 51a subsequent to moulding. The male mould (200), Figs. 14 and 17 (not shown), comprises a main block (230) with pocket-forming projections (231) and (233) and two wedge sections (250) having recesses (254) which allow formation of the handle projections 51a. The female mould comprises a bottom block (320), Figs. 13 and 18 (not shown), and side blocks (330), (340) which are undercut at (333) to provide the ridges 32a, 33a and are movable away from each other and bottom block (320) when pins (370) are moved to the left to release the ridges, and are provided with spring-loaded rods (336) which return them to the moulding position when pins (370) are withdrawn. In operation, platen 103, Fig. 1, is moved to mate mould 200 with mould 300 and synthetic thermoplastic resin, e.g. high density polyethylene, fed from a hopper 121 to a chamber 125, is conveyed by an hydraulically operated plunger 140 to an electrical heater 130 and thence when molten through a sprue hole (403), Fig. 13 (not shown), past heaters (422), (423) in passages (412-415) to the mould cavity via injection orifices in bottom block (320). The moulds are cooled by liquid flowing through passages, such as at (353) and when the resin has sufficiently hardened, platen (103) is retracted and therewith the male mould. An ejector plate (210), Fig. 17 (not shown), to which the wedges (250) are attached, is, however, maintained stationary with respect to the female mould so that by the co-operation of guide members (252) on the wedges with T- shaped slots (251) in block (230), the wedges are separated to release the handle. During this stage the carrying case is supported peripherally by ejector bars (240), see also Fig. 14 (not reproduced), and a pin (261) which grips the handle within a groove (262), both the bars and the pin being mounted on ejector plate (210). On further retraction of platen 103, ejector plate (210) and therewith wedges (250), bars (240) and pin (261) are also retracted and a frame (360), Fig. 11 (not shown), which carries pins (370) is moved to the left by co-operation of studs (376) with slotted bars (371) to cause separation of blocks (330) and (340), thereby releasing the carrying case from the female mould.

Filed: 1936-12-15
Abstract: 477,655. Winches. GENERAL ELECTRIC CO., Ltd., and MACFARLANE, G. T. Dec. 15, 1936, No. 34412. [Class 78 (v)] Means for unifying the controls of a winch having a main power shaft 6 worm-geared to the drum-shaft 1 and coupled to the coaxial motor shaft by epicyclic or other differential gearing comprises a hand wheel 20 bevel-geared to a shaft 21 carrying cams 28, 29 which actuate the epicyclic planet cage brake 9 and the unidirectional holding brake 11, respectively. On the shaft 21 is also a screw 50 on which rides a nut 51 which rocks a spring- retracted lever 55 pivoted at 56 and formed with a yoke 57 by which a clutch 14 gripping the motor shaft 6 to the brake 9 can be released. Alternatively the shaft 21 carries a helicallygrooved sleeve in which engage pins on a yoke at the top of the lever 55. Thus, when the wheel 20 is in medial position brake 11 is on, brake 9 is off, and clutch 14 is free. On turning the wheel 20 in one direction the brake 9 is applied for hoisting ; on turning it in the opposite direction, first the brake 9 and then the brake 11 are released, and, on further turning, the clutch 14 is engaged and the winch barrel driven rapidly in the unwinding direction to allow the hook to fall. The cam 28 acts to apply the brake 9, a spring releasing same when the cam returns. The brake 11 is normally applied by a counterweight, the cam 29 acting to release the brake. The wheel 20 may rotate the shaft 21 in any manner, and may be located at a distance for electric actuation. It may be devised to return automatically to medial position on release. The control may be applied also to a winch in which the epicyclic gear is carried directly on the main drum shaft, the brake and clutch mechanism being disposed on a high speed gear-driven lay shaft. Specifications 477,608 and 477,641 are referred to.

Title: Improvements in or relating to the wiping and scraping mechanism of intaglio printing machines
IPC: B41F9/10
Filed: 1927-12-20
Abstract: 310,072. Waite, F., and Waite & Saville, Ltd. Dec. 20, 1927. Inking-apparatus.-In wiping-apparatus for intaglio printing-machines, in which a wiping- member having a curved surface over which a strip of wiping-paper passes is rocked against the action of spring rods as the printing-surface moves past it, means are provided for controlling the tension of the springs so that their pressure remains substantially constant throughout the wiping operation. A shaving-blade may be provided to remove the ink from the plate prior to the wiping operation and may be readily replaced by a scraping blade when the wiping-apparatus is not required. The front end of the wiping- member 3, Fig. 1, is carried by a pair of rods 5 on which are arranged springs 4 mounted between adjustable collars 5<c> and slidable sleeves 7 bearing upon the ends of levers 6 secured to a shaft 9 on which is also fixed an arm 13. Loose upon the shaft 9 is an arm 10 engaging a cam 11 on a shaft 12 and provided with a pawl 12<a> adapted to co-operate with the arm 13. A shaft 19, which is rocked by an arm 21 and a cam 16 on the shaft 12, carries an arm 20 which operates connections 23, 24, 24<a>, and 26 for rocking the wiping-member 3 as the printing-die 14 moves past it. The rear end of the die is carried by spring rods 3& operated by a cam 41 on the shaft 12 and arms 40, 37 on a shaft 39. As the shaft 12 rotates, the member 3 is rocked by the connections from the shaft 19 and the rods 5 are depressed. Owing to the shape of the cam 11, however, the levers 6 move downwardly so that the compression of the springs 4 remains substantially uniform. At the end of the rocking movement, the levers 6 engage stops 15, and during the further rotation of the shaft 19, a bowl 18<a> carried by an arm 18 fast on this shaft engages and raises a curved arm 17<a> loose on the shaft 19, thereby raising the pawl 12<a> out of engagement with the arm 13. The wiping-mechanism may be held inoperative by means of a latch 28 placed in engagement with a projection 20<a> on the arm 20 and operable by a hand-lever 29 and link 29<a>. A shaving-blade 30, Fig. 14, such as described in Specifications 187,658 and 187.930, for removing excess ink from the die before it is wiped, is mounted on a holder 31 which can be secured by screws 33 against bearing surfaces a, b on a support 32. When printing from photogravure plates, the wiping- apparatus is rendered inoperative and a scraping blade 30<a>, Fig. 13, mounted on a holder 31<a> is secured to the support 32 in place of the holder 31.

Filed: 1974-08-06
Abstract: 1454199 Air conditioning buildings CARRIER CORP 6 Aug 1974 34567/74 Heading F4V [Also in Division G3] In an air-conditioning unit, inflatable bladders 31, 33 regulating the flow of air into the space to be conditioned are controlled by a pressure regulating valve 51 connected between the bladders and an air supply duct 17 of the unit and by a thermostat 90 which reduces the air flow as the temperature in the space falls to a predetermined value. When warm air is supplied by the duct 17 to correct excessive cooling, which may have taken place overnight, a bimetal 59 opens a port 57 to allow air from the duct 17 to flow across the thermostatic means 90 so that the bladders are controlled only by the pressure regulator 51. A number of chambers 19 lined with fibreglass 21 are connected end to end and are each fitted with a plate 23 having collared openings 25 to direct the air downwardly into a space between the bladders and a felt-covered opening 32. Plates 35 upstream of a diffuser 37 prevent turbulence and are interposed between layers of fibreglass 43 to absorb sound. The duct 17 is connected to a fan 15 drawing air from a unit containing a filter 5, pre-cooling, cooling and heating coils 2, 11, 13 and a spray producer 9.

Title: Improvements in or relating to television cameras
Inventor: HOLMAN HERBERT EDWARD
IPC: H04N5/225
Filed: 1954-12-01
Abstract: 776,300. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 14, 1955 [Dec. 1, 1954], No. 34744/54. Class 40 (3). A television camera has an axially movable pick-up tube 27 and a similarly movable lens carrying structure 41 coupling being provided between the two so that focusing can be effected by simultaneous movement in opposite directions. The movement is arranged to be such that the tube and lens structure substantially counterbalance each other when the camera is tilted. As described the pick-up tube is mounted in a housing 28 supported on rollers for backward and forward movement inside a casing 21 in the lower part of the camera. A projection 36 on the housing 28 is coupled by link 83 to a stub shaft 88 on one end of suitably bent lever 80 pivoted at 81. The opposite end of the lever 80 carries a further stub shaft 89 to which is attached link 84 whose other end is carried by strap 91 on laterally movable shaft 40 which supports the lens-turret 41. The shaft 40 is supported on roller bearings inside fixed support tube 10. It is capable of lateral but not rotary movement and carries bearings in which an inner tube carrying the turret 41 is free to rotate. As described with reference to Figs. 2 and 3 (not shown), a locating arrangement is provided for locating one of the lenses on the turret in front of the pick-up tube. By gripping handles 73, 75 at the rear of the camera the locating device is released and the turret can then be rotated by the handles to locate another lens in front of the tube 27. Focusing is effected by lever 96 coupled to crank 94 and arm 93 inside the camera. Movement of the crank is arranged to produce non-linear displacement of the focusing elements to take into account the fact that finer adjustment is required when lens and tube are close together than at the other end of the range of movement. The lengths of the arms 86 and 87 of lever 80 are so chosen in relation to the weights of the lens and tube moving structures as to provide the most effective counterbalancing. A filter 100 mounted independently of the focusing means is provided and may be rotated to bring any desired sector into the light path.
