Title: Improvements relating to automatic engine starting apparatus for internal combustionengines
IPC: F02N11/08
Filed: 1932-10-07
Abstract: 408,317. Starting prime movers. LUCAS, Ltd., J., and WATSON, E. A. Great King Street, Birmingham. Oct. 7, 1932, No. 27924. [Class 38 (iv).] In an electric starting system for internal - combustion engines in which the starter motor circuit is controlled by an electromagnetic switch a the winding d of which is controlled by a hand operated switch t and contacts n, m operated by an armature h which is controlled by a winding f in series with the motor circuit acting in opposition to a winding i in parallel with the motor e, the circuit of the winding i includes interrupter contacts r, q associated with a weighted spring o which is operated directly or indirectly by the closure of the starter circuit switch a so as to delay and prevent completion of the circuit of the winding i until the starter motor pinion has engaged the engine gear. An additional winding v assisting the winding i and energized from the engine driven generator w may be provided or, alternatively, armature h may be held down during normal operation of the engine by some other device dependent upon the motion of the engine, e.g. engine suction ; or oil pressure. In a modification the plunger c of the starter circuit switch a carries an iron sleeve slidable thereon and pressed away from the coil by a spring, the sleeve having a flange on which the iron weighted end of the spring o rests. Energization of the coil d draws down the sleeve and with it the spring blade o even after the core c has ceased moving until the blade o engages a stop on the coil, whereupon it vibrates and finally comes to rest with the contacts r, q closed.

Abstract: 467,784. Typewriters &c. HARDING, C. H. J. Oct. 15, 1936, No. 27958. [Class 100 (iv)] Counting - apparatus.- In word-counting apparatus, a counter is connected to a rocking member which is moved in one direction by depression of the letter-keys to actuate the counter and is restored idly by depression of the spacing and punctuation - keys, or by return of the papercarriage when the end word has been completely typed, means in connection with the hyphen-key being provided for preventing restoration of the bail until the end word has beencompletelytyped. In the mechanism shown in Figs. 1 and 4, a bail 6, mounted on trunnions 7 and arranged below the key-levers 5, 13 is provided with an arm 9 which is connected by a link 10 to an arm 11 provided with a pawl 11a co-operating with ratchet-teeth 12 on the units drum of a counter 3. To prevent shock, the arm 9 may be connected to the bail by a pair of strong springs 16. The letter-key levers 5 co-operate with lugs 6a on the front bar of the bail, and the spacing-key and punctuation-key levers 13 co-operate with lugs 6b on the rear bar. When the first letter of a word is typed, the bail is rocked anticlockwise and the counter is operated once. At the end of a word, depression of the space-bar or a punctuation key restores the bail or, at the end of a line, the bail is restored during return of the carriage 29 by co-operation of a lug 30 thereon with a dog 31 on a spindle 33 which is connected by an arm 34 and link 35 to the bail. When the first letter of the next word is typed, the counter is again operated once. To prevent restoration of the bail when a hyphen occurs at the end of a line, the link 35 is replaced by a pair of links 36, 37, Fig. 8, which are connected to a pivoted arm 38 on a lever 39 co-operating with a cam-groove 42a, in a cylinder 42 having an arm 43 co-operating with the hyphen-key lever. Depression of the hyphen-key rocks the cylinder 42 and causes the lever 39 to straighten the links 36, 37 and thereby move the dog 31 out of the path of the lug 30. One of the trunnions 7 may be provided with a knob for restoring the bail. If a word is counted in error, a key 17 is depressed to subtract a unit. The key carries a pawl 18, Fig. 4, co-operating with teeth 19 which are arranged reversely to the teeth 12. A cam 20 on the key is provided with parts 21, 22 for releasing the pawl 11a and a detent 24a from the teeth 12. A projection 26, and a part 23 on the cam release the pawl 18 and a detent 25 from the teeth 19 when the key returns.

Title: Improvements in mechanical stokers
IPC: F23H9/00
Filed: 1919-11-18
Abstract: 158,729. Usui, K. Nov. 18, 1919. Grates; air-supply, regulating. -In a mechanical stoker of the type in which the fire-bars are arranged transversely and are intermittently moved from the front to the back of the furnace by the insertion of individual pars in the front of the grate and the consequential ejection of individual bars from the back of the grate, improved means are provided for effecting the transference of the ejected bars from the back to the front and for inserting them in position. Superposed stationary rails 5, 17 support the grate-bars and the ejected bars respectively, the latter being moved from back to front by the reciprocating tracks 7 situated beneath the rails 17, the tracks being provided with a plurality of plates 18 which each engage an individual bar and impart the forward motion, retrograde motion being prevented by a series of depending pawls 17<1> secured to the stationary structure of the stoker. The foremost fire-bar on the rails 17 is delivered on levers 9 operated by the reciprocating tracks 7 and constrained to move in desired paths by rollers 10 and guides 12, the fire-bar being thus placed in front of a pusher 16 which forces it into position in the grate by displacing the whole grate toward the back of the furnace through a distance corresponding to the width of a fire-bar. The ejected bar at the back of the grate is received by and slides down inclined plates 8 attached to the reciprocating tracks 7, and is thus positioned on the rails 17, along which it is moved step by step to the levers 9. The grate is operated from a common shaft 14 through worm and toothed gear. ing. The air-supply is regulated by pivoted flaps 22, which are simultaneously operated by a rod 23 and levers 24, 25, and 26. Various forms of fire-bars, as shown in Fig. 4, may be used.

Filed: 1931-10-15
Abstract: 384,396. Mixing and treating charge. DICKINSON, W., Rock House, Slant Gate, Kirkburton, near Huddersfield. Oct. 15, 1931, No. 28602. [Class 7 (ii).] Extra air to a road vehicle engine is supplied through a passage E in which is located a valve G controlled by the driver. The air enters an annulus D and escapes into the induction pipe through perforations f in a ring e and is mixed with the charge therein by two pairs of blades g formed integral with the ring. The air may be dry or humidified, and to control the humidity of the air a barrel P is fitted on a part 0 carried by an extension F of the fitting A. A cylindrical rod Q has a rectangular opening V which communicates with the atmosphere through a port U, covered by a wire gauze filter a, and an opening W which communicates through a pipe T with the radiator of the water cooling system. By rotating the rod Q by a lever near the driver, atmospheric air or humidified air, or both, can be supplied to the induction pipe. To ensure that moist air is supplied and not water, the radiator overflow pipe t leads to a three-way connection u, the water escaping by opening a flap v whilst the moist air is drawn through the pipe T.
Patent GB-664225-A (GB)
Title: Method of filling thermostat tubes
IPC: G01K5/02
Filed: 1949-11-08
Abstract: 664,225. Filling thermostat tubes. VAPOR HEATING CORPORATION. Nov. 8, 1949 [Nov. 19, 1948], No. 28624/49. Class 125(ii). [Also in Group XIII] A method of filling a thermostat tube 41 with a highly oxidizable temperature sensing material, e.g. a thallium amalgam, while the tube is out of contact with the atmosphere comprises placing the tube, open at one end, into a vessel which is being flushed with a non-oxidizing fluid to remove air from within it, and which contains the amalgam out of contact with the open end of the tube, closing the vessel and providing a vacuum within it, immersing the open end of the tube in the amalgam, releasing the vacuum from the vessel and refilling it with the non- oxidizing fluid so that the pressure of the latter, which is equal to the external atmospheric pressure, urges the amalgam into the evacuated interior of the tube. A vessel 10, containing thermostat tubes 41 and having its cork 15, provided with a valve 16, removed, is flushed with nitrogen fed to it from a container 13 by way of a tube 35 and an auxiliary chamber 29. A pipe 17 connects the chamber 29 to the vessel 10 and provides with a diametrically opposite pipe (not shown), connected through a valve to a vacuum pump, a pivotal mounting for the vessel 10 on brackets 21 fixed to the upright 22 of a stand 11 which carries also an abutment 23 for the vessel 10. The cork 15, with its valve 16 open, is plugged into the vessel 10 and a quantity of amalgam stored under H 2 SO 4  in a vessel 37 is supplied through a tap 38 and a pipe 34 into the chamber 29 where it remains surrounded by nitrogen and out of contact with the tubes 41. The valve 16 is closed, the supply of nitrogen cut off and the vessel 10 and the chamber 29 are connected to the vacuum pump. While the vessel 10 is being exhausted it is heated to about 250‹F. e.g. by a lamp 40, to remove any traces of moisture within the vessel 10. The vessel is placed upright and clasped in a bracket 24 fixed to the upright 22. This movement pours the amalgam from the chamber 29 into the vessel 10 where it covers the ends of the tubes 41. The vacuum pump is disconnected from the vessel 10 and nitrogen is again flushed through the apparatus so that its pressure, equal to the external atmospheric pressure, forces the amalgam into the evacuated interiors of the tubes 41 to fill them. They are then withdrawn from the vessel 10 and sealed at their open ends. In order to leave the correct amount of amalgam in each tube, so that metal electrodes 45, 46, Fig 6, are contacted at the required predetermined temperature, the end of each tube is heated to produce vapour which expands the end of the tube into a bulb. The surplus amalgam is withdrawn into this bulb and the upper part of the tube is sealed and broken off to leave a shorter finished tube, Fig. 6. The amalgam contains 8À73 per cent of thallium.

Title: Improvements in or relating to balloon toys
IPC: A63H3/06
Filed: 1947-10-27
Abstract: 631,077. Inflatable toys. INGRAM, G. Oct. 27, 1947, No. 28644. [Class 132 (iii)] An inflatable toy comprises a balloon part which has one or more hollow resilient nipples or studs, the cavities of which communicate with the interior of the balloon so that the nipples or studs become inflated simultaneously with the main part of the balloon, the toy comprising also at least one separate part for anchorage to the balloon and which has a hole or cavity into which a nipple or stud is adapted to engage, the nipple or stud, by reason of its inflation, anchoring the attached part to the balloon. As shown, the studs 2 are of a bulbous shape and are preferably formed, during manufacture, by using a former having projections of the required shape at the required positions. Their cavities communicate with that of the balloon so that they are inflated with it. The balloon 1 is formed-with studs 2 at the appropriate positions so that legs. 3 and a head 4, which are made of cardboard, rubber or other sheet material, may be anchored to the body. Each leg 3 has a hole 5 through which a stud 2 is passed, when deflated, or only partially inflated, the hole 5 being smaller than the stud when the latter is fully inflated. Thus the legs can pivot about their respective studs. Two or more studs are used if the attached part is not to be movable : for example the head 4 is formed with base cheeks 6 having four holes through which studs are passed as described above. The toy may be made to represent a human figure.

Patent GB-1019312-A (GB)
Title: Improvements in or relating to inspection systems for detecting flaws in workpieces
Inventor: CLARK CARLOS SEBASTIAN
IPC: G01N19/08
Filed: 1962-07-25
Abstract: 1,019,312. Electric measurement and control. BURGESS-NORTON MFG CO. July 25, 1962, No. 28663/62. Heading G1N. In an inspection system for detecting flaws in workpieces, a scanning element making contact with the workpiece scans its surface, and electrical means are provided for producing a signal on vibration of the scanning element due to a flaw in the workpiece, and rejecting mechanism operates under the influence of the signal to reject a faulty workpiece when the succeeding workpiece enters the inspection system. As shown, Fig. 1, piston pins or other cylindrical workpieces are fed from a conveyer 17 via a rotating table 19 to a second conveyer 20 whereon they form an unbroken line. Conveyer 20 introduces the pins between two cylindrical drums 24, 26, slightly spaced apart and the axis of drum 24 forming an angle with the axis of drum 26, the drums being rotated so that the pins move longitudinally between them. Each pin passes between and connects contacts 32, 34 and is scanned by a detecting head 40 comprising a diamond point 60, (Fig. 7, not shown) which forms a smooth shallow spiral groove in the surface of the pin, any seam or other major flaw in the surface causing the point 60 to vibrate and producing a signal from a crystal or magnetic cartridge housed in support arm 62. Alternatively, the spiral groove may be formed by a second diamond point 60a, point 60 being used solely for pick-up purposes. The workpiece then enters a guide 46 on an inclined plate 44, so that when the next workpiece touches contacts 32, 34 the workpiece in the guide 46 is released by the opening of a gate 48 by a pneumatic or hydraulic piston (not shown) or, if a "flaw" signal has been generated, is deflected to a rejection slide 50 on movement of the guide 46 by piston 56. Circuitry. (Fig. 6, not shown) The left-hand circuit is supplied with A.C. and the right-hand circuit with D.C., whereupon the relays are in the conditions shown. Relays R1..... R5 each comprise a closing coil R1a.....R5a and an opening coil R1b ... R5b. When aworkpiece bridges contacts 32, 34, relay R7 comes up, followed by relay RA; relay RB releases, and the anode and cathode circuits of a valve T1 are closed. Relay RE closes, energizing solenoid valve SV1 to open gate 48. If a "flaw" signal is generated in the cartridge 70 it is passed via a filter 72 and amplifiers 74, 76 to the grid of T1 and, if it is of sufficient strength, it causes the energization of relay RC in the anode circuit of T1. Relay RD comes up, extinguishing green lamp G and causing red lamp R to glow, and energizing relay coil R5b which closes contacts R5. When the next workpiece bridges contacts 32, 34 and relay RA closes, causing relay R2 to open, relay RF is energized; this closes reject mechanism solenoid valve SV2 to operate piston 56 and deflect the previous, faulty, workpiece to the reject slide 50. A mechanical or electrical counter may record the number of defective workpieces.
