Title: Improvements in starting means for internal combustion motors
IPC: F02N3/02
Filed: 1934-12-10
Abstract: 441,577. Turning - gear. AKTIEBOLAGET PENTAVERKEN, Gothenburg, Sweden. Dec. 10, 1934, No. 35453. Convention date, Feb. 8. [Class 7 (v)] In an arrangement for starting an engine in either direction of rotation, two pulleys K, k each have a flexible member such as a cord G, g wound thereon and are connected to an engine shaft A in such a manner as to start the motor in one or other direction of rotation on pulling one of the flexible members. As shown, the pulleys K, k are enclosed in a casing E, F mounted on the engine housing, the hubs B, b of the pulleys being one within the other. A return spring S is attached at one end by a bolt D to the pulley K and at the other end C to the hub b of the pulley k, preferably by being bent and inserted in a slot in the hub. The cords G, g are secured at their inner ends to the pulleys and at their outer ends to handles H, h normally abutting against the ends U, u of cord passages in the casing. The pulleys K, k may be connected to the engine shaft A by pawl-and-ratchet devices or by one-way frictional couplings comprising balls, rollers, &c. As shown, a pawl L pivoted on the stud D co-operates with a ratchet wheel O on the shaft A. A releasing member consisting of an eccentric quadrant M is pivoted at V to the pawl L and bears on a guide edge N on the casing F. The member M is connected by springs X to an arm P pivoted at R on the opposite side of the pulley. On pulling the cord G by means of the handle H, the rolling of the member M on the guide edge N brings the pawl L into engagement with the ratchet wheel 0 and the shaft A is rotated and the return spring S tensioned. When the engine starts in the desired direction the pawl L is swung away by the member M, and on releasing the handle H the cord is re-wound on the pulley by the spring S. If the engine starts in the wrong direction, the pawl L is disengaged by the rolling of the member M on the guide edge N. The pulley k is connected to the shaft A by a corresponding ratchet and pawl arranged to turn the shaft A in the other direction and to be disengaged if the shaft turns in the wrong direction. The Specification as open to inspection under Sect. 91 comprises also a modification in which a single pulley and cord is provided for starting in one direction only. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to apparatus for copy-turning
IPC: B23Q35/10
Filed: 1954-12-08
Abstract: 795,240. Copy-turning. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.- GES. Dec. 8, 1954 [Dec. 18, 1953], No. 35516/54. Class 83 (3). A copying - lathe, e.g. for pistons, comprises a tool 24 in a holder 16 slidable towards and away from the work-axis 11 by feelers 6, 13, 19 acting through a frame 17 pivoted to an arm 17a on the holder. Feeler 6 is pivoted on trunnions 6a and is urged to engage the periphery of a cam 8, rotating with the work, by a spring 9. An arcuate surface 5 passing through the trunnion centres is engaged by the nose 12 of feeler 13, which is pivoted at 18 to the frame and engages a template 15 with an arcuate surface 14 corresponding to surface 5. Feeler 19 is integral with the frame 17 and is urged by spring 20 to engage a template 21. Template 15 controls the longitudinal shape of the work, e.g. conical, by causing feeler 13 to pivot about its nose 12 and so move frame 17 and the tool. Cam 8 has a shape corresponding to the cross-section of the work, e.g. oval, but has no effect on frame 17 if nose 12 lies on the trunnion axis. The movement of the nose relatively to this axis is controlled by a template 21 and feeler 19, whereby the cross-section can be varied along the length of the work. Thus, if template 21 is flat and parallel to the work-axis, the work will be circular at any cross-section, and if template 15 is also flat and parallel to the work-axis, the work will be cylindrical. If longitudinalcontrol is not required, parts 13, 15 may be omitted and nose 12 made rigid with frame 17.

Abstract: 448,868. Prepayment mechanism for meters. WILSON GASMETERS, Ltd., G., Foleshill Road, Coventry, WILSON, J. H., The Mill House, Baginton, near Coventry, and ORMEROD, G. A., 24, Ash Tree Avenue, Coventry. Dec. 12, 1934, No. 35654. [Class 27] In bi-coin prepayment mechanism for meters which includes planetary gearing between the quantity mechanism and a pair of driving wheels selectively actuated on the insertion of appropriate coins, the planetary gearing includes two coaxial wheels, at least one of which is an internally-toothed annulus. The coin-pocket casing 13, Fig. 1, contains driving wheels 14, 15 held against rotation in one direction by pawls 16, and rotated respectively in the other direction after the insertion of a shilling or a penny by a projection 17 on a slider 18. In each case the driven element of the planetary gearing is a wheel 24 meshing with a pinion 25 on a lay-shaft 26, the pinions 24, 25 being a speed-increasing gearing. The lay-shaft through speed - reduction worm gearing 29 rotates one sun-wheel 27 of an epicyclic quantity-mechanism, the other sunwheel 30 of which is driven by the meter, and the planet-wheel 28 of which actuates a valvecontroller 35 and an indicator. The planetary gearing transmitting the drive from the wheels 14, 15 to the pinion 24 comprises an internallytoothed annulus 38 secured in a recessed face of the wheel 14 and an externally-toothed wheel 40 carried by a spindle 39 fast with the other driving wheel 15. The planet element comprises compound spur wheels 41, 42 rotatably mounted on an arm 43 of a planetcarrier 44 which is fast with the wheel 24. The gear ratios are such that the wheel 24 is rotated twelve times as much by actuation of the " shilling " wheel 14 as by actuation of the " penny " wheel 15. In a modification, Fig. 3, the wheel 14 carries a toothed annulus 46, the arm 43 of the planet-carrier being fast on the spindle 39 to which the other driving wheel 15 is secured. The driven gear 24 is fast with an internally-toothed annulus 47. Specifications 387,678 and 448,862 are referred to.

Title: Improvements in apparatus for adding oil to liquid or gaseous fuel
IPC: F02M17/28
Filed: 1932-12-16
Abstract: 401,126. Lubricators. TECALEMIT, Ltd., Great West Road, Brentford, Middlesex. Dec. 16, 1932, No. 35772. Convention date, Dec. 16, 1931. [Class 12 (iii).] Apparatus for adding oil in a constant proportion to the liquid or gaseous fuel feeding an internal-combustion engine, in which use is made of the phenomenon of capillarity between an oil container 1 and the fuel pipe, comprises means which ensure a considerable difference of pressure between the ends of at least two capillary members, this difference of pressure being transmitted from one capillary member to the other through the oil. In Fig. 1, the pressure difference is ensured by a restriction 4b in a pipe joint 4 forming part of the fuel pipe, and the capillary members comprise wicks 10, 11 held respectively in tubes 8, 9 screwed into a plug 6 on the container 1 which is screwed into the lateral extension 3 of the pipe joint. The wicks are in contact with both media and the tube 9 extends nearly to the bottom of the container. In a modification, the wicks are replaced by capillary holes and the pipe joint is stepped to provide a seat for a spring-pressed valve which closes the fuel outlet when the container 1 is removed. For this purpose the valve has a tail which in the assembled position contacts the plug 6. In another form, the tube 9 which has a capillary orifice is soldered to a disc in which a small cup is stamped. The cup contains a felt plug and has a small hole at its base. The container has a screw cap for use when removed from the pipe joint. Very narrow tubes may be used instead of wicks, or plugs.

Patent GB-401508-A (GB)
Title: A process for cracking tar oils or crude tars by heating under pressure in the liquid phase
Filed: 1932-12-19
Abstract: <PICT:0401508/III/1> Oils are cracked by passing the crude oil into a distillation column in which it is fractionated into a benzine distillate, middle oils, and pitch, the middle oils being circulated through a cracking coil and the products returned to the distillation column in which they are expanded in contact with the pitch and part of the crude oils.  Crude oil preheated in a heat exchanger 54 is pumped from a tank 13 through a line 47 on to trays of a fractionating column 38 surmounted by an upper plate column 55. Fractionation may be aided by a steam coil 58 and the benzine fraction passes off through a line 74 and condenser 76 to a separator 77 from which water is removed through a pipe 80 and gases through a pipe 86 while the condensate is collected in a receiver 85 or refractionated if required in a column 90 and condenser 103.  The middle fractions are collected from plates in the column 55 and pass through pipes 59, 65, 66 to receivers 62, 70, 73 from which they are pumped to the cracking coil 3 and recirculated to the bottom of the fractionating column through a line 6.  The cracked products pass through a weighted valve 4 into an oil bath maintained at the bottom of the column by pumping part of the crude oil through a line 51 and by passing part of the residual oil from the bottom plate 38 through a line 41.  The cracked products injected upwardly through a cone-shaped pipe 19 against a baffle 20, distil the oil in the bath 15 to a pitch which is removed continually through a cooler 16 to a receiver 18.  The cracked vapours then pass upwardly through a central pipe 24 formed in an evaporating vessel 23, in which the residual oil flowing from the upper part of the column is heated indirectly by the vapours, the liquid being maintained at a constant level by an overflow 26 and syphon 27 which discharges the heavy residues through a pipe 28 and cooler 31 to a receiver 33.  The heat exchanger 54 is heated by flue gases from the furnace 1.  The oil cycled through the cracking coils becomes gradually enriched in naphthalene.

Abstract: 468,215. Ball-and-ring mills. BABCOCK & WILCOX, Ltd. Dec. 30, 1935, No. 35983. Convention date, Dec. 29, 1934. [Class 59] In a ball-and-ring mill having upper and lower grinding stages in series with a discharge outlet at the top of the casing, means are provided for directing a stream of air upwardly through the casing in a flow path successively sweeping the material discharged from the lower and upper stages, and means adjacent to the discharge side of one of the stages for varying the velocity of the air stream. As shown the centre ring 13 is non-rotary and the upper and lower rings 12, 14 are driven by the shaft 15. Pressure is applied to the upper and lower rows of balls 19, 16 by springs 23 carried by a frame 24 secured to the top of the driving shaft 15. Material to be ground falls from a shoot 25 to the outside of the row of balls 19 and after being ground is discharged to the inside of the lower row of balls which completes the grinding and discharges the material centrifugally into an airstream ascending through an adjustable orifice 32. The airstream passes inwardly through orifices 35 in the centre ring 13 and then ascends to a discharge outlet 11, an adjustable bell 36 regulating at a restriction 38 the velocity of the air flowing past the inside of the upper row of balls 19. In a modification the centre ring 13 is driven by the shaft 15 and the casing 30 is bulged near the extremity of the conical baffle 39 to allow for any rocking movement set up by the ring 13. The bell 36 is adjustable from outside the mill bv the movement of a screwed rod passing through the cover. Valved openings may be provided in the baffle 39 and automatic means may actuate one or both openings 32, 38 in accordance with the quantity of air supplied.

Filed: 1953-12-29
Abstract: 741,715. Take-up motions for circular looms. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE. Dec. 29, 1953 [Dec. 30, 1952], No. 36068/53. Class 142 (2). A take-up motion comprises two obliquely superposed horizontal drums 23, 24 between which the flattened tubular fabric passes, both drums being roughened and driven at the same peripheral speed and both being in contact with the fabric over equal arcs so that the fabric is not creased or distorted. At least one smooth, driven roller 29 guides the fabric after it leaves the drums. A roughened driven roller 30 and a presser roller 31 may be provided. Alternatively, two driven rollers may be provided, and arranged side-by-side with the fabric passing between them. The drum 24 is pressed towards the drum 23 by a spring 27 that is adjusted by a screw 28. The roller 29 is driven at a higher peripheral speed than the drums 23, 24 and the roller 30 is driven through a friction coupling at a speed which would be greater than that of the roller 30 if there were no slip. The drums 23, 24 are driven by a connection from the picking mechanism through a clutch, a gear train, and a lost-motion device and the take-up is delayed for a certain time interval or for a certain number of picks after the restarting of the picking-mechanism. The time delay is effected by electromagnetic operation of the clutch, the delay occurring while a condenser is being charged, after which, a solenoid in parallel with the condenser causes the clutch to engage. The delay for a definite number of picks is effected by the lost-motion device after engagement of the clutch. The device winds up a spring or a weight until sufficient torque is available to drive the take-up. The take-up can be stopped automatically upon interruption of the picking and can also be stopped manually. If a cam or a clockwork mechanism is provided, the take-up can be interrupted at regular intervals to provide a fabric having bands of crammed wefts.
