Patent GB-133289-A (GB)
IPC: F02M19/10
Abstract: 133,289. Chandler, M. G. Oct. 4, 1918, [Convention date]. Spray carburettors.-A suction-feed carburettor is arranged to maintain a partial vacuum in the float chamber, in spite of variations of pressure in the mixing chamber, by means of Venturi tubes arranged as shown. One such tube 14 made with a step 30 receives fuel through a passage 9 inside the supporting webs 33, controlled by a valve 11, and primary air through the outer end. Supplementary air enters through a throttle valve 17 under the control of a piston 20, the space 21 above it being open to suction through ports 27 in the main choke tube 13. A small Venturi tube 35 projects into the air current as shown, and is adjustable so as to present an opening 37 more or less obliquely to the current; ports 36 at the narrowest part of the tube communicate by a passage 10 with the float chamber air space, and ports 38 with a point beyond the throttle, past an adjusting valve 39. With suitable adjustments of the spring 22, the tube 35, and the different valves, the carburettor is stated to be self-regulating under all conditions, whether using hot or cold air.

Stationary-mould machines; delivery; moulds; moulding rings.-Comprises apparatus for automatically moulding articles such as clay rings for inverted incandescent mantles and transporting the moulded articles to a conveyer &c. Material is fed to a mould A comprising sections 32 hinged together at 35 and opened and closed by a frame 34 reciprocated through a rod 33 by a cam 31 on a shaft 23, and is compressed by a top die D operated from the shaft 23 through a disk 20, roller 21, tappet lever 9, link 8, toggle 7, 6, and lever 5. During pressing, the die is held down by a spring catch plate 1 furnished with a projection 29 which engages behind a pin 28 on a lever 16 connected to the lever 9, the parts being retained by a roller 22 on the disk 20 engaging the lever 16. After pressing, the mould is opened and the article is raised by a bottom plunger 42 which is operated by a tappet lever 26 engaged by the roller 21. A transporter E comprising arms 49 recessed at 50 to engage the plunger 42, is rotated intermittingly by ratchet mechanism 48 operated by a cam 30 on the shaft 23 to bring a recess 50 into engagement with the raised plunger, which is then lowered, leaving the moulded article upon an arm 49. A fixed abutment sweeps the articles from the transporter on to a conveyer. To provide better support for the articles, the transporter may be provided with hinged portions 51 mounted upon spring pins 52 and opened by a fixed cam 54. The material is fed to the moulds by a hopper supplied by a bucket chain.

Title: Improvements in chewing gum base and method of making same
IPC: A23G4/06
Filed: 1931-05-06
Abstract: In the preparation of a chewing-gum base by mixing rubber, hard fat or wax, and resin, burnt rubber taste is avoided and a better consistency is ensured by keeping the working temperature always below 120 DEG  C.  The rubber is mixed with hard fat in a cooled roller mill and the resin with more fat is incorporated in the presence of water in a steam-heated mixer.  In an example, 50 parts "latex rubber" is milled until its strength has been considerably reduced; mixed on the milling machine with 50 parts hydrogenated cotton-seed oil (M.P. 56 DEG  C.); stripped from the rolls and allowed to stand for a period varying with the hardness of the required product; mixed in a jacketed open mixer heated by steam under pressure with 150 to 300 parts coumarone resin (equal parts low-melting, say 60 DEG  C., and high-melting say 140 DEG  C.); washed, and the kneading continued with addition of 400 to 500 parts water and 50 to 250 parts hydrogenated peanut oil until a uniform mix is obtained, which may retain 5 to 10 per cent water; the product is then run out into pans.  The proportions may be widely varied.  All or part of the rubber may be replaced by purified pontianak or jelutong.  Chicle may be added.  The hydrogenated oil may be replaced wholly or in part by tallow, beeswax, &c. and in part by paraffin wax, cocoa butter, coconut oil, white mineral oil, &c.  Other resins may be used in place of coumarone.ALSO:In the preparation of a chewing-gum base by mixing rubber, hard fat or wax and resin, burnt rubber taste is avoided and a better consistency is ensured by keeping the working temperature always below 120 DEG  C.

Filed: 1927-05-25
Abstract: 291,946. Withers, J. S., (Sentry Safety Control Corporation). May 25, 1927. Kinematograph apparatus.-A cutoff shutter is carried by a shaft rotatable in a casing and having a notched collar normally engaged by a trip to hold the shutter in inoperative position, the trip having one end extending outside the casing and being actuated by an electromagnet to permit the shutter to fall when irregularities occur in the film field; the shutter may also be released upon breakage of either of two driving belts, or upon failure of the driving motor current. and its falling operates a mercury switch to stop the driving motor. As shown, a shutter 16 is carried at one end of an arm 15 secured to a shaft 14 in a casing 10<a> secured to the light cone 18 of a projector, the other end of the arm 15 being provided with a pivoted latch 17 pulled by a spring so as to ride over the casing 10<a> and engage a notch 20 when the shutter has fallen, thereby holding the shutter in position. The shaft 14 has a notched collar 23 normally engaged by a pivoted trip 25 linked by a pin 32 and slot 31 to an armature 29 pivoted at 30, the armature being raised, when an electric magnet 28 is energized, to release the collar 23 and allow the shutter to fall. The energization of the magnet 28 is effected by means of a transformer 81, having its primary winding connected in parallel with the driving motor 71, when either of two switches 83, 84, respectively above and below the gate, and controlled by the film, is closed. The shaft 14 also carries a cam 33 which, in turning, allows a spring arm 34, carrying a mercury switch 36, to move downwards and cause the circuit through the switch to be broken. The switch 36 is included in the circuit of an electromagnet 38 normally attracting an armature 41 carrying a contact bar 49 closing the circuit 77, 78, 79 of the driving motor 71. Breakage of either of two belts 69, 72 driving the projector may also cause stoppage of the motor by means of a contact 63, included in the circuit of the electromagnet 38, and carried by one end of a centrally pivoted lever 52, the other arm of the lever being forced downwards to break contact, by a cam 62 on a roller arm 63, or by a roller 73, upon breakage of either of the belts 69, 72. Upward movement of the armature 41 causes a flexible cable 66 terminating in a button 68 to raise the extended end 26 of the trip 25 and release the shutter 16.

Latches, sliding; preventing operation of.- The latch-follower is rendered inoperative when the latch is shot by means of a slide arranged on the latch-bolt and held in its extreme positions by a spring-plate attached to the bolt. The slide 5, which has a projection 6 adapted to engage a projection 4 on the latch-follower 3, and an upper part 7 adapted to bear against the casing 1, is provided with teeth 9 with which a keyoperated rack 17 engages to move the slide. Before the slide can move, however, a spring-plate 13, secured on one end of the 'bolt 2 and abutting against a projection 8 on the slide, must be raised by a key-operated cam-disc 16 acting on an arm 15 of the plate, it being so arranged that rotation of the key operates both the cam-disc 16 and the rack 17. From inside the door, an arm 18 on a handle 19 engages a hole 10 in the slide 5, and, on being moved, first raises the plate 13 by striking against the cam-shaped projection 14, and then moves the slide to the right, Fig. 1. In a modification, Fig. 9, the slide 20, having a projection 21 to engage the projection 4 of the follower and arches 22 bearing against the casing 1, is kept in place by means of a hook 28 on a spring-controlled plate 26 adapted to catch into one of the two holes 24 in the slide. The plate 26, removably attached to the bolt 2 by hooks 27, is operated by a key acting on the arm 29 to lift the hook 28 out of the hole 24 in the slide, further movement of the key moving the slide, after which the hook 28 enters the other hole 24, thus securing the slide in its new position.
