Title: Improvements in and relating to injection moulding machines
IPC: B29C45/53
Filed: 1964-05-27
Abstract: 1,065,442. Injection moulding machines. W. ZALEWSKI. May 21, 1965 [May 27, 1964], No. 22009/64. Heading B5A. [Also in Division B8] In an injection moulding machine, Fig. 1 (not shown), of the kind wherein a pneumatically or hydraulically-operated injection piston and an injection cylinder move vertically downwardly to bring the injection nozzle into contact with a mould and to thereafter inject molten material, e.g. rubber or plastics, into the mould, a positive feed device is situated within hopper (18), (19) which operates to feed starting material into the injection cylinder when the injection piston is in its uppermost position. In this position, Fig. 2 (not shown), an aperture (30) in injection cylinder (27) is uncovered and a pawl (51) is released from engagement with an abutment (54) on the connector portion between injection piston (12) and rod (11). The pawl, connected by a chain or cable (46) to a pivoted arm 40, Fig. 6, tensions a spring 43 and retracts a pusher 35 during its rise with the injection piston. On release of the pawl, pusher 35 moves towards apertures 30 under the action of spring 43 to feed material therethrough and pawl (51), Fig. 2 (not shown), is pulled downwardly by cable (46) to await its next engagement with abutment (54). In a modification, pusher 35 may be reciprocated by solenoid means. The lower portion (28) of the injection cylinder is provided with a torpedo (61) having vanes (63), band heaters (64), (65), and thermal insulation (67) and (71). A conventional valve (74) is provided in outlet (79) which latter may be modified to give a horizontal injection path. The injection cylinder (27), (28) is held in position by a pivoted lever (81), (86), Fig. 3 (not shown), which engages a recess (87). Injection cylinder (12) may be disconnected from piston rod (11) by the lateral removal through apertures (100) of 1-sectioned link (60). Cylinder (10), Fig. 2( not shown), and guide cylinder (25) may be withdrawn as a unit from hopper (18), (19) by unscrewing a nut (26).

Abstract: 616,003. Frictional lighters. PERMUTA (PLASTICS), Ltd., P. A., and BUTLER, P. T. July 24, 1946, No. 22033. [Class 75 (iii)] The cotton wool or other absorbent in the wick compartment 7 of a pyrophoric lighter is fed with fuel spirit from an auxiliary tank 11 detachably held in the bottom of the lighter casing 1 and having a valve controlled conical outlet 14 engaging in a hole 10 in the bottom 6 of the compartment. The valve being operable from outside the casing. The tank 11 is secured to the bottom 6 by a screw 20 which may be hollow to contain spare flints 21 and which extends through a central tubular portion provided in the auxiliary tank, this tubular portion serving for the main charging of the cotton wool. A screwed plug 18 in the tank 11 may be removed through an opening 19 in the casing 1 when the tank is to be refilled. The valve 16 controlling the outlet 14 is operable by a screwed plug 15.

Title: Improvements relating to methods of conveying pulverulent or quasi-liquid material from a tank by means of compressed air
IPC: B65G53/12
Filed: 1935-08-03
Abstract: 460,778. Conveying pulverulent and semi-liquid material. JORGENSEN, M. VOGEL-. Aug. 3, 1935, No. 22038. [Class 102 (ii)] In apparatus for conveying pulverulent material by means of compressed air, the level of the material in a tank 1 influences photo-electric cells or condensers which control relays for operating the valves. A tank 1 is filled with material through a valve 10 operated by a solenoid 11, the material being discharged through a pipe 14 by compressed air supplied through a pipe 12 controlled by a valve operated by a solenoid 13. When the level of material in the tank rises above a photo-electric cell 2 exposed to a lamp 4 the current in the circuit of the cell is interrupted and relays are operated for breaking the circuit of the solenoid 11 and making the circuit of the solenoid 13. The valves are thus operated and are held in the closed and open positions, respectively, by latches operated by solenoids, which are energized when the level of the material in the tank falls below a photo-electric cell 3 thus exposing it to the lamp 5. In a modification the photo-electric cells are replaced by rings which, with the walls of the tank 1, form condensers, the capacity of which is altered by the rise and fall of material in the tank and thus operates relays for the valves.
Patent GB-793638-A (GB)
Title: Improvements in or relating to the grinding of ring-like workpieces
IPC: B24B19/06
Filed: 1955-08-02
Abstract: 793,638. Grinding. LANDIS TOOL CO. Aug. 2, 1955 [Aug. 2, 1954], No. 22111/55. Class 60. A method of grinding ring-like workpieces to their external diameter includes rotating the workpiece, feeding a grinding wheel against the external peripheral surface of the workpiece, stopping the feed of the wheel at a predetermined point and then grinding the said surface to a predetermined diameter by feeding the workpiece against the grinding wheel until the desired diameter has been reached. A workpiece such as the inner race of a ball bearing with its end faces ground parallel and the internal surface ground to predetermined size, has its external surface ground to the desired diameter and concentric with the internal surface in a machine comprising a grinding wheel 18 carried by a slide 15 fed by a piston 20 in a cylinder 19 under the control of a valve 24 which is operated by handle 25 to initiate the feed. The internal surface of the workpiece W is engaged by shoes 11, 12 on an arbor 10 mounted in arm 10a movable from loading position to operating position in which one end face of the workpiece is engaged by a magnetic chuck 14 on a rotating spindle 13. A workpiece feeding shoe 32 is carried by a bar 33 mounted at the upper ends of flexible steel members 34, 34 anchored to a block 35 secured to the machine base. A compression spring 38 urges the bar 33 towards the workpiece. A shaft 41 has fixed to one end an arm 42 co-operating with a pin 40 mounted in a block 39 secured to the rear end of the bar 33 ; fixed to the other end of the shaft 41 is an arm 42a connected to the core of a solenoid 47. During the feed of the grinding wheel the solenoid 47 is energized, thus holding the bar 33 retracted from the workpiece, the workpiece being then located by both shoes 11, 12. The grinding wheel feed ceases when the slide 15 contacts a stop 27 ; this closes a fluid exhaust port 28 in the stop 27, the consequent rise in fluid pressure operating a switch 50 to deenergize the solenoid 47 thus permitting the spring 38 to move the bar 33 into contact with the workpiece which is thus rocked about the shoe 11 and fed towards the grinding wheel. When the desired diameter is reached the feed ceases due to contact of the block 39 on the bar 33 with an adjustable stop 49. The operation of the switch 50 at the end of the grinding wheel feed also brings into circuit a timer relay 51 set to close a switch 52 after the feed of the workpiece has ceased, closure of switch '52 energizing solenoid 53 to shift the valve 24 to cause withdrawal of the grinding wheel to its retracted position. As the port 28 is uncovered, the switch 50 returns to normal and the solenoid 47 is energized to withdraw the bar 33 from the workpiece, thus completing a cycle. Specification 712,024 is referred to.

Abstract: 663,088. Fluid-pressure presses. HODEL, A. Aug. 26, 1948 [Aug. 26, 1947], No. 22492/48. Class 122(iii) [Also in Group XXIX] In a veneer press of the type in which a movable platen 8 is operated by fluid (e.g. water or air) under pressure supplied to the interior of a flexible sided inflatable member such as a flexible rubber bag 5, a displaceable frame 9 is provided to prevent the bag from being forced out from a sheet metal container 1 when the platen rises above the top of the container. The frame presents to the marginal part of the inflatable member a continuous face inclined outwardly and downwardly and avoids sharp bends in the bag. The frame 9 is advantageously made of angle-irons in which strips of wood having a triangular cross-section are inserted. The bag may be replaced by a container covered by a diaphragm. The Specification as open to inspection under Sect. 91 states that the frame 9 may be connected to the platen 8 but if workpieces of uneven shape are to be veneered the plate 8 must be removable so that the work-pieces can be laid with the veneered side on the bag 5. This subject-matter does not appear in the Specification as accepted.
