Title: Improvements in starting means for internal-combustion engines
IPC: F02N5/04
Filed: 1946-02-19
Abstract: 608,318. Inertia starters. SAMPIETRO, A. C. Feb. 19, 1946, No. 5222. [Class 7 (v)] An internal-combustion engine 10 connected to its load by a main friction clutch 26 has an inertia starting system comprising an electric motor 29 connected to the driven clutch element which constitutes at least part of the fly-wheel mass, the starter motor being associated with speed-responsive means wherebythe clutch is automatically engaged to turn the engine when the driven clutch element attains a predetermined speed. In the application to a road vehicle, the clutch is actuated by an electromagnet 16 which when energized coacts with an armature 15 to engage the presser plate 22 with the driven clutch plate 26 splined to the shaft 12 of the change-speed box 13. The starter motor 29, connected to the shaft 12 by belt gearing 28, normally acts as a generator for charging the battery 30, Fig. 2, using a shunt field winding 31. The starter switch has normally closed contacts 35 and normally open contacts 36, 40. Contacts 36 are in circuit with a relay coil 37 and series field winding 38 and contacts 40 to electromagnet coil 16 and to back contacts 39 controlled by the relay. In operation, when the starter switch is operated to start the engine, the heavy initial motor current operates relay 37, breaks contacts 39 and interrupts the clutch energizing circuit. When the motor attains about 1000 r.p.m., the reduced current causes the relay 37 to close contacts 39, thus engaging the clutch 26 so that the inertia of the clutch parts assists in turning the engine. If the engine does not start before the motor speed falls to about 400 r.p.m., the relay operates again and the starting operation is repeated. When the engine starts the starter switch is released thus cutting out the series winding 38 and breaking the circuit of coil 16. The clutch control circuit for normal driving is not shown in Figure 2.

Abstract: 1,168,833. Recovering yeast &c. BRITISH PETROLEUM CO. Ltd. Jan.13, 1967 [Feb. 9, 1966], No. 5640/66. Heading C6F. Contaminants consisting of, or comprising, at least one hydrocarbon and water are removed from a solid material (micro-organism) by extracting the contaminated solid material, in an extraction stage consisting of one or more extraction steps, with a mixture of an alcohol and a hydrocarbon with which it forms an azeotrope, these being employed in the mixture at a ratio by volume within the range 30: 70 to 70:30. The treated solid material from the first extraction stage may be further extracted with a mixture of the alcohol and azeotrope-forming hydrocarbon in a second extraction stage. The extract fractions from the first and second extraction stages, either separately or after blending, are fed to a distillation stage for the separate recovery of; (a) an azeotropic mixture of the alcohol and the azeotropeforming hydrocarbon, (b) an azeotropic mixture of the alcohol and water, and (c) a residue fraction. Substantially all the azeotropic mixture of the alcohol and water is blended with part of the azeotropic mixture of the alcohol and azeotrope-forming hydrocarbon to give a mixture of the alcohol and azeotrope-forming hydrocarbon containing these materials at a ratio by volume in the range 30:70 to 70:30 for recycling to the first extraction stage. The contaminated material preferably is diluted with water before the extraction to give a ratio of water to total alcohol and azeotrope-forming hydrocarbon mixture added in the range 1:4 to 1:10 by weight. Examples are directed to extracting the following micro-organism products, after partial refining by centrifuging, treatment with a specified surface active agent and washing with water until the hydrocarbon content was less than 7% based on the dry weight of the micro-organism; (1, 3 and 5) Candida tropicalis or Hansenula suavesleus after cultivation upon a heavy gas oil of petroleum origin; and (2 and 4) Candida utilis after cultivation upon mixed C 10 -C 20  hydrocarbons containing normal paraffins. The solvent mixture consisted for the first extraction stage of 50% by weight of n-hexane and of isopropanol, and for a second extraction stage of 80% by weight of n-hexane and 20% by weight of isopropanol. The products were almost entirely freed from lipids.

Title: Device For Applying Elastically Deformable Capsules To Bottles
IPC: B67B5/00
Filed: 1968-02-05
Abstract: 1,158,092. Capping bottles, &c. VISCOSE DEVELOPMENT CO. Ltd. 5 Feb., 1968 [3 Feb., 1967], No. 5703/68. Heading B8T. A device for applying elastically deformable capsules to bottles comprises a plurality of fingers 42 hinged to arms 31 which are pivoted to a common mounting ring 2. The ring 2 is carried on an arm 15 which is vertically reciprocable by means of a crank 181. The fingers open up the capsule 6 as the bottle neck passes into the opened-up capsule through the fingers. Radial movement of the arms 31 allows the fingers closely to follow the shape of the bottle. The capsule holds together the fingers and arms against the pressure of a spring loading 5. The device may be operated, as one element of a bottling plant, on stationary bottles, delivered by a Maltese Cross 10, and operated in conjunction with a capsule feed 19 which drops capsules on to the generally cylindrical chuck 42 formed by the upper end of the fingers. At the beginning of the process, when the vertically movable members 15, 2 are near their highest point, a radially extending sawtooth projection 31<SP>1</SP> on each arm 31 bears against a conical surface 32 on a ring 33 carried by a bell 17<SP>1</SP>, so holding- each arm against the spring loading. As the crank 181 rotates, thereby lowering the members 15, 2, the arms 31 extend outwards urged firstly by the spring loading 5 and later by the pressure of the bottle neck on the lower sector 40 of the fingers, thus expanding the capsule over the bottle neck. When the arms 31 approach their lowest point, the fingers pass below the end of the capsule, the spring loading 5 urges the arms apart and springs 44<SP>1</SP> urge each of the fingers towards a direction parallel with the longitudinal axis of the bottle. This prevents the fingers from touching the bottle on the upstroke of the device.

Title: Improvements in and relating to the braking of electrically propelled rail vehicles
IPC: B60L7/00
Filed: 1929-02-21
Abstract: 329,668. Maley, A. W., and Taunton, E. M. Feb. 21, 1929. Electric and magnetic; fluid-pressure.-In an electrically-propelled rail vehicle having regenerative or rheostatic braking and an air wheel brake controlled by a separate handle, but no air track brake, the controller handle when brought to electrical braking notches operates a valve by which the wheel brake cylinder is connected to exhaust. In one modification an exhaust valve in parallel with the air brake exhaust valve is opened by a cam on the controller spindle when this is moved to the electrical braking notches. A restriction in the air supply prevents serious loss of pressure if the air brake handle is held on. In a further modification arranged to prevent this loss of pressure an additional exhaust valve is arranged in parallel and an additional inlet valve in series with the corresponding air brake valves and these additional valves are operated by the controller spindle. In a further modification the controller spindle operates valves 9, 10 to admit or exhaust air to or from a pneumatically operated valve 11 which is adapted to connect the brake cylinder 3 either to the train pipe 13 or to the exhaust 14. Specification 294,593 is referred to.

Title: Improvements in "turnstile mechanism"
IPC: G07F17/14
Filed: 1922-02-27
Abstract: 182,436. Hedley, r., and Doyle, J. S. June 25, 1921, [Convention date]. Turnstiles locked normally against entrance and free for exit are unlocked by the insertion of a coin acting through electric and pneumatic means, the stile being simultaneously locked against exit. Means are also provided to prevent a too rapid rotation in either direction. To ensure complete quarter-turns, the turnstile shaft 16 has a fixed collar 21 serrated on its lower edge to co-operate with a similar non-rotatable member 22 slidably mounted in slotted brackets 24 and pressed upwards by a spiral spring 26. In a modification, the spring is omitted and the weight of the turnstile arms and shaft are relied upon to control the positions of rest. Mounted upon a bracket 45 are two oppositely disposed bent pawls 47 pivoted at 50 and arranged in conjunction with channelled members 53 secured to.the supporting-plate 19 of the turnstile arms. If the turnstile is rotated too rapidly, the end 52 of one pawl is pushed upwards by the action of one projection 54 upon the pawl nose 49 and cannot fall again before engagement by the following projection 54. To the turnstile shaft is attached a ratchet-wheel having peripheral teeth 31 and crown teeth 32, engageable by pawls 34, 35 respectively which are controlled by a spring-influenced spindle 37 having an arm 39 in contact with the rod 40 of a piston in a cylinder 41. When compressed air is admitted to the latter and the spindle 37 is rocked, the pawl 35 is freed and the arm 36 disengages pawl 34 to allow forward rotation of the turnstile. When the pressure is released, the pawls re-engage, the pawl 35 entering a deep notch 33, of which there are four corresponding in position with the turnstile arms. When the turnstile is arranged for release by insertion of a coin, a four-contact commutator 28 is fixed on the spindle 16 and is engaged by a pair of brushes 30 in series with a source of supply 59, Fig. 13, and a relay 65. When the inserted coin bridges the contacts 57, 58, the relay 65 is energized to break circuit at 60, complete a relay holding circuit at 62 and by a contact at 63 close a circuit g, including the magnet 63 controlling the admission of compressed air to the cylinder 41. As soon as the turnstile is rotated and the circuit consequently broken at 28, 30, the relay 65 is de-energized and the circuits and the devices controlled by them resume their normal condition, the magnet 66 thereupon allowing the cylinder 41 to exhaust to permit return of the spindle 37 and the re-engagement of the pawls 34, 35.

Title: Moulds for forming articles provided with internal screw threads
IPC: B29C45/26
Filed: 1959-02-20
Abstract: 845,080. Injection moulding apparatus MADSEN, E. F. Feb. 20, 1959, No. 5929/59 Class 87(2). [Also in Group XXII] Internally threaded articles, e.g. screw caps, are injection moulded on a rotatable core 78 having a screw threaded end 80, the core 78 extending through a mould plate 36 which remains in engagement with the article while the core is being unscrewed from the article. In the example the mould comprises two parts 10, 12, the part 10 containing nine cavities 18. Material is injected through passages 20, 22. After injection, the part 12 is moved away from the part 10 and then the cores 78 are rotated through gearing 92, 93 by a shaft 94. Rotation of the moulded caps is prevented by ribs 112, Fig. 3, on the mould plate 36 which is urged away from the other plates 32, 34 of the mould part 12 by springs 42. As the shaft 94 rotates, it disengages a threaded extension 104 from the sprue in passage 20, and the sprues in passage 22 are pushed outwardly by rods 130 and severed from the moulded caps at narrowed parts 26 of the injection passages. The rods 130 are actuated by springs 132 or by compressed air. Compressed air supplied through a nozzle 128, channels 126, 120 and grooves 122, 124 assists in removing the moulded caps from the cores 78.
