Title: Work-holding fixtures
IPC: B23Q3/06
Filed: 1946-11-08
Abstract: 620,853. Chucks. DEARBORN, J. W. Nov. 8, 1946, No. 33239. Convention date, May 1. [Class 83 (iii)] A work-holder and indexing device comprises an indexing head 56, a chuck 71 in the head, and an indexing arm 142 which has an eccentric face 166 at one end and is pivotally supported by a member 141 carried by the head so that pivotal movement of the arm moves the eccentric face into frictional engagement with the head and rotates it in the direction of movement of the arm. The chuck collet 72 is closed by springs 93 acting on a ring 82, and is opened by upward movement of lugs 181 against the ring 82. The lugs 181 are formed on a horseshoe member 175, pivoted at 179, which is supported at the opposite end by a lever 185 pivoted on a second lever 43 carried on a shaft 41 which is turned to open the collet by a manually- or automatically-operated chain 191. As the shaft 41 is rotated, a further lever arm 192 mounted thereon is turned to engage a pawl 208 with a bell-crank 214 pivoted at 211 which raises an ejector 118 detachably mounted on the end of the bell-crank. The latter is returned by a spring-plunger 213. Indexing.-The head 56 carrying the collet is engaged by yoke arms 143, 144 and a tongue 150 of the member 141. The handle 142 pivoted at 169 is constrained between a spring- pressed plunger 173 and an adjustable stop 1710. Clockwise rotation of the handle indexes the head, and reverse rotation releases the eccentric 166 and the stop 173 engages the member 141 to return it. Two scales are provided on a base 22 for adjusting a stop 28 coacting with the upper scale and engaging a fixed stop 153 on the member 141 for angles up to 90 degrees and a stop 32 coacting with the lower scale and carrying a lug 36 to engage a plunger 156 for angles between 90 and 180 degrees. In the latter case, the plunger 156 is depressed on a second swing of the handle. The head 56 is held in adjusted position by brake-shoes 127 which are pressed against the holder by levers 129 pivoted at 130 and forced apart by a spring 140. The holder may be rotated by a pawl 163, shown disengaged in Fig. 1, engaging teeth 70.

Title: Improvements in change speed mechanism
IPC: H02J7/16
Filed: 1930-11-06
Abstract: 363,074. Controlling variable-speed gearing. ROYCE, SIR F. H., Nightingale Road, Derby. Nov. 6, 1930, No. 33398. Addition to 355,437. [Class 80 (ii).] The invention relates to changespeed mechanism as described in the parent Specification, which comprises a selector switch arm adapted to be moved one way or the other to turn an electric motor in either direction, and with the motor a changegear controlling cam shaft and a switch drum which cuts off the current and stops the motor at the end of a gear change. According to the present invention the switch drum e forms part of the circuit of the motor armature b. The armature b drives the change-gear cam shaft (not shown) through worm gearing, and the commutator drum e is secured to or geared to the cam shaft. The drum e shown developed in Fig. 2 comprises two conducting segments f f<2>, f<3> separated by an insulator f passing round the drum from and back to a cross-bar f <1>, with a step f<4>. The drum may be regarded as comprising three zones e<1>, e<2>, e<3> shown separately in section in Fig. 1. The brushes g, g<1> which connect the armature b to the drum are duplicated so as never to be cut out by cross-bar f<1>. The gear selector is a double switch arm with parts d, d<1> positive and negative respectively with respect to the source of current a. The brushes 1 .. 4 shown dark and light are positive and negative respectively. As shown, the first gear is engaged, the cross-bar f<1> insulating the dark and light brushes 1. To change to second, switch arms d, d<1> are turned to terminals 2. The current passes from arm d to dark brush 2, segment f<3>, brushes g<1>, through armature b, brushes g, segment f<2>, light brush 2, to arm d<1>, field winding c, back to battery a. The motor will turn driving the cam shaft so that the developed drum of Fig. 2 moves to the right. This movement is terminated when cross-bar f and step f4 come under dark and light brushes 2 respectively. On moving double arm d, d<1> one way or the other, the armature, drum and cam shaft follow it, and stop.

Filed: 1975-08-11
Abstract: 1512668 Hydraulic control circuits CATERPILLAR TRACTOR CO 11 Aug 1975 [12 Aug 1974] 33429/75 Heading F1P An hydraulic control system having lift cylinders 17, and a pilot operated directional control valve 16 for the cylinders comprises a pump 13, which supplies pilot fluid to a pilot valve 56 for operating the control valve 16, and a shuttle valve 79, which allows fluid to flow from the load side of the cylinders 17 to the pilot valve when the pump 13 is inoperative due to engine failure, and normally closes the connection to the pilot valve when the pump 13 is operating. Thus, if the engine fails when the piston-rods of the cylinders 17 are extended and under load, the shuttle 79 is moved downwards by a spring 81 from the position in which it is normally held by fluid pressure, and this connects line 83 to line 82 so that pressurized fluid is supplied to the pilot valve 56 so that the control valve 16 can be moved to the "lower" position. Any residual pressure below the pistons in the cylinders 17 is exhausted through a bore 85 in the pilot valve. A pump 12 supplies fluid to the control valve 16.

Title: Finishing treatment of filamentary materials
IPC: D06B3/04
Filed: 1961-09-20
Abstract: 999,248. Filament - finishing apparatus. CELANESE CORPORATION OF AMERICA. Sept. 20, 1961 [Sept. 26, 1960], No. 33654/61. Heading B5B. [Also in Division Dl] A compact strand of filaments is uniformly treated with a treatment agent by passing the strand through a passageway (37, Fig. 2) wide in relation to its height and into which a stream of fluid under high pressure and carrying the treatment agent is fed in a direction transverse to the direction of travel of the strand (the strand travelling in a direction perpendicular to the plane of Fig. 2) the passageway being of substantially greater cross-sectional area than the strand and the inlet thereto and outlet therefrom for the strand being dimensioned so that a substantial part of the fluid discharges through the inlet counter-current to the entering strand, whereby the filaments are separated from each other before reaching the point where the fluid enters the passageway. The fluid, preferably air, may be directed on to the filaments in the form of streams, suitably 0À004-0À01 inch thick and much wider than their thicknesses, the width of each stream forming an angle between 30 degrees and 60 degrees with the direction of movement of the filaments. The streams may be directed on to the strand of filaments (travelling in the direction of the arrows a, Fig. 4) through two groups of slots 21, 22 in a wall 14 (Figs. 2, 4) of the passageway 37, the slots in. one group being arranged substantially transversely to those in the other group so that the two groups define a herringbone pattern. The slots may be of trapezoidal cross-section the wider end opening into the passageway 37, and the axes of the slots being preferably vertical with respect to the plate 14. The two groups of slots may be at an angle of 0-120 degrees to each other. The slots may be replaced by rows of holes. A strand may contain more than 5000 filaments and be pulled through the passageway under a tension less than 15 mgm. per filament. Apparatus comprises plates 15, 14 and spacers 33, 34 defining a passageway 37 for the strand having a pair of opposing walls 15, 14 wide in relation to the height of the passageway, one of the walls (14) having perforations, and means for supplying a fluid under pressure thereto (tube 38, 10 and the chamber formed by the recessed base plate 16 and the perforated plate 14), and means for introducing a treatment agent into the fluid on its way to the perforations (pipe 41, nozzle 43). The pipe and nozzle may alternatively be fitted axially in the tube 38. If desired the plate 15 may be slotted, the slots being offset from those of plate 14. In operation, air is supplied via 38 and treatment agent via 41, admission of the strand to the passageway effected by swinging back plate 15, which is secured to plates 14 and 16 by the hinge 30 and spring clip 29. Air leaves the passageway on both the filament inlet and outlet sides, and thus serves to separate the filaments as they enter the passageway, enhancing the uniformity of application of the treatment agent.

The drive unit 5 for the signal plate unit comprises a receiver 24 the output from which controls a relay 23. When it is desired to give a " go '' signal to the traffic at one of the signal points control 3a in transmitter 3 is operated to a position which causes a signal to be transmitted which is picked up by the required receiver only to operate its relay 23. Contact 21 then changes over completing the circuit to motor 16, rotating the signal unit until cam 26 opens switch 19. The motor then stops and the green " go " signal is displayed. Switch 27 also rotates to complete the circuit to the lamp 28, or 29. illuminating the " go " signal when switch 37 is closed. When control 3a is returned to neutral relay 23 is released, and the motor rotates the signal unit, unit cam 25 opens switch 18. The motor then stops and the red stop " signal is displayed, its associated lamp circuit being completed by switch 27. In an alternative construction. Figs. 10, 11 (not shown), a single fixed lamp is used, and a reflector rotating with the signal unit directs the light on to the required signal surface. A pair of signalling units of the type described may be employed for controlling traffic from two directions.

Title: Improvements in or relating to the treatment of distilled water
Inventor: BARDSLEY NORMAN
IPC: C02F1/00
Filed: 1955-11-26
Abstract: Distilled water is rendered more palatable and non-corrosive to metal by chlorinating the water, introducing temporary hardness into the water and subsequently dechlorinating the water.  The chlorination may be effected prior to or subsequent to the introduction of temporary hardness, employing sodium hypochlorite solution as the chlorinating agent, while the dechlorination may be effected by passage of the water through a bed of activated carbon.  The temporary hardness may be introduced into the water by passage through a bed of calcium carbonate (e.g. limestone chippings) in the presence of dissolved carbon dioxide. The carbon dioxide may be extraneously introduced or may result through the use of sea-water, containing magnesium and calcium bicarbonates, as the raw water which is distilled.  The taste of the water may be improved by dissolving air therein before or after the treatment.  Alternatively, the air may be introduced during the treatment by admitting the water into the air space in the vessel containing the bed of activated carbon in the form of a spray, and also supplying compressed air to the air space, so that air is dissolved in the water.  Means may be provided for periodically reversing the flow of water through the bed of activated carbon, or through the beds of activated carbon and calcium carbonate.  Means may also be provided for sterilising and reactivating the carbon bed by periodic injection of steam. Apparatus for carrying out the process of the invention is described. Specification 801,011 is referred to.

Title: Improvements in apparatus for cooling and ventilating dynamoelectric machines
IPC: H02K9/10
Filed: 1921-12-19
Abstract: 172,983. Bartel, W., and Happel, O. Dec. 20, 1920, [Convention date]. Cooling air, tubular apparatus for.-In an aircirculation cooling system for turbo-dynamos and other electrical machines, the air conduit from the machine to the cooling appliance is substantially uniform in cross-section, so as to convey a steady current of air to the cooler, and the conduit between the cooler and the machine air inlet has an enlargement or chamber directly in the normal air path whereby the air velocity is reduced materially so that its contained liquid particles are deposited before reaching the machine. In the arrangement shown, hot air passes out from an opening 3 beneath a generator 1 and through a trunk 4 into a chamber 14 containing the cooler. Thereafter the cold air passes into the enlargement or chamber 6, where its moisture is deposited and whence the air flows to the generator at 7, for instance under the action of a fan on the rotor shaft. Specifications 157,562 and 159,282, [Class 137, Ventilation], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter :-The cooler consists of a number of horizontal sets of gilled tubes through pairs of which in parallel water flows from an inlet 9 to the outlet at 10. The tube units are divided centrally so that the water flows in opposite directions in the halves of each unit. By means of valves 12, any unit may be shut off for endways withdrawal without interrupting the flow, horizontal ledges 13 and air-tight doors opposite the headers 8 being provided in the chamber 14 for this purpose. The tubes 17, as shown in transverse and longitudinal sections, Fig. 6 (Cancelled) and Fig. 5 (Cancelled). are of oval section excepting their circular ends in the plate 20, and carry gills 18 secured by a zinc dipping or the like and formed of plates having pressed-up dovetail tongues 19 which rest on the adjoining gills. The tongues and longer dimension of the tubes are in the direction of the air flow to minimize the air resistance. Any moisture carried by the circulating air, due for example to leakage of the cooler, is deposited in a chamber which, as in the form shown in Fig. 1, may be the chamber 6 from which the air flows directly into the generator. Baffles may be used for collecting the water and leading it to a container where it closes an electric circuit, or any other alarm device or a moisture gauge may be employed in the air circuit. The cooling water from the cooler may be used to make up losses in the condenser circulating water. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 121,005 and 163,079, [Class 35, Dynamo-electric generators &c.].

Indicating duration of flow of liquids.-In liquid-measuring apparatus comprising a pump adapted to deliver a definite quantity of liquid over a weir into a delivery pipe, the liquid remaining at the level of the top of the weir when the apparatus is at rest, windows are provided through which the level may beobserved with the help of a float, and flow-indicators may be fitted to show when liquid is passing. A combined flow and flow-indicator 32 is shown, slidably mounted on a rod 34 on the pump side of the weir 12 and arranged so that when the liquid is at the level of the weir it shall be visible through a window 16; it consists of a hollow spinner which rotates when liquid flows over the weir into the delivery pipe 10. If the liquid level falls due to evaporation or leakage the float will drop out of sight. To determine accurately the level there may be a mark on the glass at the level of the weir and a liquid-level line on the spinner. In modifications a ball in a wire cage is used as float and a fixed spinner to indicate the flow. Specifications 8558/04, 17943/12 and 148,483 are referred to.
