Title: Improvements in taximeters
IPC: G07B13/00
Filed: 1940-02-22
Abstract: 537,880. Taximeters. FABRIKS AKTIEBOLAGET HALDATAXAMETERN. Feb. 22, 1940, No. 3381. Convention date, March 2, 1939. [Class 106 (iii)] Relates to mixed time and distance meters in which the totalizers are actuated through oneway clutches and pinions from a road wheel and from a clock respectively and consists in that the pinions and/or drivers co-operating therewith are provided with friction braking devices to minimize errors at their coupling. The totalizers, not shown, are moved step by step to a tooth 3 on a lever 1 pivoted at 2 and adapted to engage and be reciprocated by a toothed wheel 4 loose on the shaft 5. This wheel is actuated by a spring 6 connected to the shaft by a pin 7 at one end and at the other to a pin 8 extending through a tooth of the wheel 4 into a recess 9 in a washer 10 fast at the shaft 5. In the path of the pin 8 are stop pins 11, 12 which are removably inserted into holes in the washer 10 to determine the time period or distance covered by the initial charge. A spring pawl 15 normally retains the wheel 4 in the inoperative position, the stop pin 11 owing to action of spring 6 being in contact with pin 8. Pinions 16, 17 carried by pivoted arms 20, 21 are driven by a vehicle wheel and by a clock respectively in known manner. Pinions 22, 23 loosely mounted on the shaft 5 may be coupled thereto by one-way clutches 24, 25. These pinions are provided with brakes. Fig. 2 shows two friction clamps 33, 34 on arms 37, 38, pivoted at 35, 36, embracing the hub of pinion 22 and connected together by a spring 39. Fig. 1 shows the clamps disengaged by the action of a pin 40 on the lever 1 against an extension 41 of the arm 38. The brake for pinion 23 consists of an additional pinion 43 in line with it which pinion gears with a pinion spring pressed axially against the lever 21 carrying it. When the meter is switched on for registration, the lever arm 1 is released and falls until pin 46 strikes pivoted lever 15. This movement releases the brake device which grips pinion 22. At about the same time, during which wheels 16, 17 are engaged with pinions 22, 23, the friction pinion is brought into engagement with pinion 43. If the cab is at rest when the meter is switched on, the shaft 5 will at first be rotated clockwise through pinion 17 by clockwork. Upon the cab starting, the driver 16 becomes operative and takes over the drive. The brake device prevents back lash between wheels 17, 23. When the shaft 5 rotates so that stop pin 12 strikes the pin 8, the wheel 4 will be caught by the shaft 5 and driven counter-clockwise. The pawl 15 slides over a tooth and into the next gap. Before this, the lever 1 is released by the upper end of lever 15 slipping off pin 46 and the tooth 3 is engaged and the totalizer actuated.

Title: Improvements in shuttleless looms
IPC: D03D47/00
Filed: 1945-02-12
Abstract: 614,466. Shuttleless looms; forming selvages; beat-up motions. FROST, W. H. Feb. 12, 1945, No. 3417. [Classes 142(ii), 142(iii) and 142(iv)] A loom for fabrics other than narrow ware has two weft inserting needles, one at each side of the loom, operating alternately and sprung so that the head of each needle bears against the reed and slay as it moves through the shed, during which movement the slay is stationary; the needles are stationary whilst the slay B, Fig. 26, is given a beat-up movement by grooved cams A. The needle H at one side of the loom is gripped by jaws J, Fig. 5, on a carriage E' reciprocated by a crank D<SP>2</SP>, which gives the needle a simple harmonic motion into and out of the shed; the needle (which has a hollow end H<SP>5</SP>) is then deposited on a support pin O, Fig. 2b, and released by the jaws. Beat-up occurs during the next half revolution of the crank D<SP>2</SP>, after which weft is inserted by the other needle (operated by a carriage coupled to the carriage E') and beaten up. The cycle of two picks and two beat-ups occupies three revolutions of the crank D<SP>2</SP>. The jaws J are opened and closed by cam slots (not shown) in bars J<SP>1</SP>, J<SP>2</SP>, Fig. 5, operated by a lever K under the control of a cam-operated shaft L' (Fig. 2b) and a link M', which moves an abutment into the path of the upper or lower end of the lever K as required. When a weft needle is at the inner end of its stroke, a pin Q<SP>13</SP>, Fig. 7, enters the loop of weft and (as the needle is withdrawn from the shed) moves it towards the fell: The pin Q<SP>13</SP>. is mounted on an arm Q<SP>10</SP>, Fig. 3, coupled by toothed gearing Q' to a sector Q carrying pins Q<SP>3</SP>, Q<SP>4</SP> Two such mechanisms (one at each side of the loom) are mounted on a bar P‹, Fig. 2b, each end of which is carried on a bell crank lever P<SP>2</SP> and loaded by a spring P<SP>8</SP>. Each bell crank lever houses a rod P<SP>1</SP> which is projected rearwards (by the shafts L') as the crank D<SP>2</SP> reaches dead centre; the carriage which is then at the inner end of its stroke strikes the rod at that side of the loom, turning the bell crank lever about its pivot P<SP>4</SP> and thus moving that end of the bar P‹ forwards. The other end moves towards the slay and the pin Q<SP>3</SP> of the mechanism mounted on it engages a stop Q' which turns the sector Q, thus bringing the pin Q<SP>13</SP> down into the weft loop. As the carriage E<SP>1</SP> moves away from the rod P', the bar P<SP>6</SP> returns to its normal position, so that the pin Q<SP>13</SP> draws the weft loop towards the fell. During beat-up, a striker B<SP>3</SP> on the slay displaces the pin Q<SP>4</SP> to disengage the pin Q<SP>13</SP> from the weft loop. Selvages are produced by changing the shed at each edge of the fabric only when the weft needle at that side is about to operate, whereas in the body of the fabric the shed is changed for every pick.

Title: Improvements in or relating to railway track circuits
IPC: B61L23/16
Filed: 1951-02-14
Abstract: 733,852. Track relay circuits for railway signalling systems. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Feb. 14, 1951 [Feb. 21, 1950], No. 3553/51. Class. 105. The track-circuit relay of a section (not subdivided in any way) is supplied with two voltages, one from the track circuit in the usual way and one derived from a local source which acts in the sense to produce a positive opening action in opposition to the holding action of the first voltage whereby increased sensitivity to the shunting by the train axles is obtained. Fig. 1 shows a two-element A.C. track relay the track winding V of which, receiving current from the track circuit, has in the lead to such track winding a, secondary t3 of a transformer T3 which applies an opposing voltage which by itself would act to give a positive opening action to the relay. The curve U2 of Fig. 2 shows the voltage applied from the track circuit as a function of the resistance between the rails (ballast resistance r and train shunt Sh in parallel) and if the dropping voltage for the track relay is taken as Us then ordinarily a very low train shunt corresponding to point A on curve U2 would be needed to drop the relay. With the inserted opposing voltage U3 of the transformer T3 the relay will drop at a much higher train shunt corresponding to point C. A condenser C3 may be connected across the transformer secondary t3 to give the resonance value when the primary winding is open, e.g. on breakage of a lead thereto; this ensures that the relay will drop if such a breakage occurs. A condenser C1 gives the necessary dephasing of the current in the local and track coils of the relay. The opposing voltage U3 may be given by a current transformer N such opposing voltage then increasing as the ballast resistance decreases. For a D.C. magnetic type track relay M1 the opposing action on the armature N is effected by a magnet M2 energized by the feed to the track circuit. Adjacent track circuits are of opposite polarity and accordingly any leakage across the insulated rail joint will drop the relay.

Title: Apparatus for Filling Powdered or Granular Material into Bags or other Containers
IPC: B65B1/16
Filed: 1967-01-25
Abstract: 1,164,026. Bag filling machines; pneumatic conveyers. FMC. CORP. 25 Jan., 1967 [28 Feb., 1966], No. 3641/67. Headings B8A and B8C. [Also in Division G1] A bag filling machine of the type in which material is fluidized in a closed chamber, the chamber being pressurized to provde a constant head above the material being discharged, includes time delay means controlling the material inlet and outlet valves and the pressurizing air so that after each filling operation, the material is permitted to flow into the chamber to make good approximately the amount discharged. The shut-off of the discharge is controlled by scale balance means. Inlet to the chamber 46 from a hopper 24 is controlled by a butterfly valve 29. A valve 199 controls the pressurizing air and fluidizing air enters the chamber directly from a pipe 163 and a plenum chamber 36 formed on a door 52 in the base. The chamber has a transparent front cover (49), Fig. 2 (not shown). The filling nozzle 26 has longitudinal grooves permitting escape of air and is pivoted by a pneumatic motor 114 to clamp or release a bag in cooperation with a shoe 94. Its flexible connection 62 to the chamber passes between bars 80, 81 of a pinch valve, see also Fig. 3 (not shown), the bars being linked to press or release the connection by a pneumatic motor 74. The bag rests on a saddle 124 with supports 120 and 122 which are adjustable for various bag sizes. When a filled bag is released from the nozzle, the saddle base tilts to eject it. The whole, together with the nozzle and damper means is suspended from scale beam 130 having counterweights 140, 146, the latter being adjustable for weight variation. When the desired weight is reached, the beams engage a pneumatic valve operating contact 152 causing closure of the pinch valve and of pressurizing air valve 199 and release of the bag. Also, the valve 29 is opened and adjustable time delay means retains it open before initiating the reverse operations to commence filling of another bag. When the valve 29 opens, the residue of air pressure escapes through the incoming material facilitating flow by preventing blockages. Reference has been directed by the Comptroller to Specification 918,104.

Title: Lung ventilator
IPC: A61M16/00
Filed: 1971-02-02
Abstract: 1382238 Lung ventilators BRITISH OXYGEN CO Ltd 2 Feb 1972 [2 Feb 1971] 3742/71 Heading A5T A lung ventilator includes an inspiratory flow conduit 20 including an inspiratory valve 8, an expiratory flow conduit 22, including an expiratory valve 28, a monitoring device 12 to produce signals corresponding to the inspiratory gas volume, means 38 to produce reference signals corresponding to a desired inspiratory volume, a comparator 36 for comparing the inspiratory gas volume signals and the reference signal and a delay device 50 to close the inspiratory valve 8 and open the expiratory valve after a chosen delay period when the signals are equal. During inspiration the gases are mixed at 2 and pass through devices 4, 6 to regulate the flow pattern and flow rate and are controlled by the inspiratory valve 8. Signals of the inspiratory volume are passed from sensor 12 to the comparator 36 via an integrator 14 which also operates a tidal volume gauge 46. The oxygen content may be analysed at 18 before the gases pass through a valve 16 to the patient. When the signals from the integrator 14 equal the reference signals, the comparator 36 actuates a control device 10 which closes the inspiratory valve 8 and the valve 34. If switch 52 is closed the valve 34 is closed immediately whereas if the switch is open the delay device 50 is used to delay the closure of valve 34. Closing the valve 34 reduces the gas pressure in line 30 allowing the expiratory valve 28 to open and operates a pressure-sensitive switch 54 which switches on a timer 40 to time the expiratory phase. The timer then resets the comparator which causes the control device 10 to open the valves 8, 34 to permit inspiration. The delay device incorporates a capacitor which is charged by the signal from the control device 10 until its potential equals that produced by a signal generator. The potential of the generator is adjustable to determine the delay. A sensor 26 in the expiratory conduit is connected to a minute volume gauge 42 and an alarm 44.

Title: Improvements relating to jib- or slewing-cranes
IPC: B66C23/00
Filed: 1923-02-08
Abstract: 214,763. Uellner, P. Feb. 8, 1923. Jib cranes.-The jib A is mounted to swing on an inclined axis f so that the horizontal projection of the path of the jib-head sheave c is an arc of the ellipse II instead of the usual circular arc I. By this arrangement the vertical plane containing the load rope a - - is slued whilst the load rope is less liable to foul the masts, shrouds or deck-structures of a ship. By leading the load rope over a sheave such as b on the crane post, the height of the load is kept approximately constant whilst slueing. Two'jibs may be mounted on one platform with the axes f arranged so that the jib-heads approach closely when over the ship's hatch.

Title: Automatic equipment for the conveying, raising and lowering of goods
IPC: B65G49/04
Filed: 1961-02-01
Abstract: 969,337. Conveyers for electroplating baths. O. H. A. LAMMERT. Feb. 1, 1961 [Feb. 2, 1960], No. 3818/61. Heading B8A. In an electroplating apparatus articles are carried by arm 15, and arm 15 is carried by carriage 29, which itself is carried by carriage 8. Carriage 8 is guided at 13 so as to be driven along a row of electrolytic baths by means of an endless chain (not shown) entrained round sprocket 10. The chain is driven intermittently to progress the carriage from bath to bath. Lifting apparatus.-The lifting into a bath and out of a bath is effected by a bridge 100 consisting of three bridge parts 23, 24 and 25. The bridge is given an up and down movement by frame 49 operated from motor 36 by the linkage shown. The three bridge parts are differently pivoted to frame 49, as follows. The carriage 8 is progressed by the chain drive from bridge part 23 to 24 and from part 24 to 25. Part 23 raises; part 24 maintains height; part 25 lowers. Thus, bridge part 23 raises carriage 29 to lift arm 15 out of a bath; and to effect this part 23 is pivoted to frame 49 so that as it descends unloaded to pick up the next carriage it can pivot idly as it passes this carriage so as to get beneath it to raise it at the subsequent movement. Bridge part 24 is made rigid with frame 49 so that when the carriage 29 is received from bridge part 23 in the elevated position the carriage is enabled to run along the bridge part 24 on to bridge part 25. Bridge part 25 is pivoted to frame 49 such that part 25 is caused to engage arm 15 by the engagement of roller 33 with cam 34 and to lower the carriage 29 to its lower position; but to swing outwards to avoid the arm 15 whilst rising to make the next lowering movement. Operation.-The article, lifting arm 15 and carriage 8 form a unit which is progressed stepby-step along a bath with the article disposed in the lower position for the purpose of being plated. The progression continues till the article meets the wall of the bath. At this stage the bridge 100 comes into play, the bridge reciprocating in the vertical direction first to bring bridge part 23 beneath the arm 15, then to lift said arm to the upper position; at which the arm runs from part 23 on to part 24, then moves from part 24 on to part 25 which lowers the arm into the next bath. In this way, the unit is taken past the bath wall and the article is lowered into the succeeding bath. If the article is required to avoid the succeeding bath arm 15 moves from part 24 on to a rail 32 which maintains the article in the raised position in which it is progressed without being plated.
