Title: Improvements in dial bore gages having an extended range
IPC: G01B5/08
Filed: 1961-03-24
Abstract: 942,154. Dial bore gauges. STANDARD GAGE CO. Inc. March 24,1961 [March 28, 1960], No. 10947/61. Heading G1M. For covering a wide range of bores, a bore gauge having a dial 12,the pointer of which is driven by a shaft 32, is provided with interchangeable gauging heads of different size. As shown in Figs. 3 and 5 the (medium-sized) gauging head is a block 18 having a fixed contact button 18 and a measuring plunger 25 movable in a sleeve 24 to transmit motion via the T-lever 31 to shaft 32. A U-shaped centering yoke 35 can slide in guideways 34 of block 18 and is provided with centering pins 36, 37 urged by springs 40 against the bore interior. The block 18 is carried on a sleeve 14 fixed to the dial housing 10 by set screw 15. An outer sleeve 42,rotatable on sleeve 14 by handle 48, carries a pin 46 engaging a pin 45 of the yoke 35 whereby the latter can be retracted towards block 18 to allow free movement of the gauging head within the bore. For larger bores a larger yoke is used (the pin 45 then engaging an aperture in the yoke) the screw 21 carrying the contact button 20 being adjusted in its bearing 22 to approximately the right extent. The yoke is prevented from coming away from block 18 by a spring clip 41 which may be placed in either of two grooves on sleeve 24. The measuring plunger 25 may also be retracted together with the yoke by engagement of the latter, when it is retracted, with a pin 53 carried by the plunger 25 and extending through a slot 54 in sleeve 24. When a small-size gauging head is fitted sleeve 14 is separated from housing 10 to allow reversal of sleeve 42. The part 44 of the latter then serves as the turning handle for retracing the yoke, a pin on the latter being engaged by a notch in sleeve 42 which when the sleeve is the other way round serves to engage with the handle 48. The latter is integral with a washer 47 which is removed when the small-size gauging head is in use.

Title: Electrical distribution system
Inventor: HOLLANDER JOHN MICHAEL
IPC: H02G5/04
Filed: 1962-03-22
Abstract: 957,128. Distribution systems. E.M.S. ELECTRICAL PRODUCTS Ltd. March 15, 1963 [March 15, 1962], No. 10956/62. Heading H2E. An electrical distribution system comprises an extruded aluminium duct 10 interiorly supporting parallel conductors 19, 20, 24, 25, 26 in insulating strips 18, 23 and having a narrow longitudinal slot in the lower side, and a flat tapping member 27 with laterally extending, spring-pressed contacts 28, 29 at one side for coaction with conductors 19, 20 and contacts 30, 31 and 32 at the opposite side for coaction with conductors 24, 25, 26. The slot in the duct permits the tapping member to be inserted edgewise and then turned through a right angle to bring its contacts into engagement with the conductors. To ensure correct engagement between each contact and its respective conductor the conductors are staggered at opposite sides of the duct with respect to each other and either the slot is not central of the lower side or as shown one lip of the slot is thickened 14a to coact with a surface of the tapping member to prevent the tapping member being turned through a full right angle in the wrong direction. The tapping member may have grub screws to bear on the wall portions 14 and 15 to prevent the tapping member from turning out of its operative position. Portions of the slot not occupied by tapping members are closed by rubber or metal inserts (Figs. 4 and 5, not shown). Separate lengths of duct can be joined end to end by engaging a dovetail slide over the respective dovetail ridges 11. In a further embodiment, Figs. 6A, 6B, the duct is formed from mating halves 44, 45 having a dovetail interconnection at 48, the mating halves being longitudinally staggered so that their respective extending ends serve for the dovetail connection to them of further aligned mating halves. At one end of each halve the insulating strip 18 is cut back to form recess 55 so that the conductors extend beyond insulating sleeves 19a, 20a and overlap corresponding conductors which extend beyond the plain end 54 of an adjacent complementary half through similar insulating sleeves 19a, 20a. The overlapping ends of the conductors have aligned holes 56 through which screws 57 are passed to engage in a connector 58 of insulating material which also has insulating plates 59 to shroud the conductors from their neighbours and the easing. Half the thickness of each overlapping conductor is cut away so that they are aligned and the screw 57 coacts with an internally screw-threaded ferrule in the connector (Fig. 9, not shown). Recess 55 is afterwards closed by a cover-plate 60. Each half may also have upright flanges 46, 47 which abut each other and jointly form a beading 67 to be clamped between jaws of a banger for the system (Fig. 10, not shown).

Filed: 1921-04-15
Abstract: 181,548. Chadwick, J. C., Holt, E., and Chadwick, F. April 15, 1920. Feeding openers, &c.-The fleece passing from one unit to another of a breaking-up or other machine is passed into a transverse chamber where it collects and from which it is removed by means which seize a section of the fleece and positively invert it, so that it is fed forward to the next unit with the less worked face upwards. The fleece passes from the calender rolls a, a<1>, Fig. 3, and is directed upwards by a roller c into a transverse chamber formed by a vertically sliding bar b with projecting fingers b<1>. The accumulation of the fleece lifts the bar b and the fleece is removed by the co-operation of the roller c, which is fluted over half its periphery, and a similar roller d. These rollers rotate faster than the rollers a, a<1> and tear off a section of the fleece, which has been inverted, and pass it, with the aid of a carrying roller e to the feed-rollers g of the next breaking cylinder. The various sections are pieced together as they pass through the feed-rollers. The device is supported in a frame h<2> with a hinged cover h<1>, and can be attached to existing machines. The fleece fed forward by the calender rollers a, a<1>, Fig. 8, may be controlled by a continuously driven fluted roller c<x>, and a second fluted roller d controlled by an oscillating toothed quadrant j driven by a crank k. The reverse movement of the roller d banks up the delivered fleece, and then the forward movement seizes a section of the fleece and by co-operation with the roller c<x> feeds it forward in an inverted position to the rollers ex, g. The rollers c<x>, d<x>, ex are driven at a greater speed than the calender rollers and feed-rollers, and the forward speed of the roller d is greater than its reverse speed.

Title: Electrical clock-work
IPC: G04C3/04
Filed: 1926-04-28
Abstract: 251,639. Butticaz, E. April 28, 1925, [Convention date]. Electric c l o c k s ; escapements. - T h e armature of an electromagnet imparts impulses to an escapement lever, the escapement being provided with means for governing the periodicity of energization of the electromagnet. The magnet 1 is connected from one pole 2 of the source of current through wire 3, stud 4, spring 32 and post 33 to the other pole. The armature 5 is carried on a spring 6 which is fixed at 7, works between banking pins 8, 9, and 10 and carries a spring 11 with a pawl 12 which engages ratchet teeth 13 on a wheel 14 geared directly to the clock hands. An escapement of the lever type is used, a tooth 27 on the armature coacting with a pallet stone 26 on the lever 20 which is pivoted at 19, works between fixed banking pins 24, 25, and has a fork 21 co-operating with an impulse pin 22 on a disc 23 rigid on the staff 28 of the balance wheel 29. This staff also carries a disc 30 with a pin 31 for stressing the spring 32. With the balance wheel 29 swinging clockwise, Fig. 2, when the pin 22 is in the centre of the fork the pin 31 presses the spring 32 against the stud 4, energizing the magnet 1, whereby the armature moves down and draws the wheel 14 on one tooth. Immediately afterwards the p'n 31 wipes off the end of spring 32 breaking the circuit and the pin 22 moves the lever 20 counterclockwise so that as the tooth 27 on the armature rises it encounters the undersurface of the pallet 26. As the wheel 29 returns counterclockwise the pin 31 wipes past the spring 32 and the pin 22 swings the lever 20 clockwise until the tooth 27 is able to move up the inclined face of the pallet 26 and to impart from the spring blade 6 an impulse, through lever 20 and pin 22, to the balance wheel.

IPC: A24D3/02
Filed: 1968-03-07
Abstract: 1,221,346. Tobacco smoke filters. CIGARETTE COMPONENTS Ltd. 7 March, 1968 [8 June, 1967], No. 11228/68. Heading A2C. [Also in Division D1] A fibrous rod of tobacco smoke filter material is made by bringing a fibrous material and a bonding constituent into rod form and activating the bonding constituent to adhere the fibres of the material to each other at their points of contact to form a deformation resistant rod, the fibrous material in continuous filamentary form being fed continuously to a cutting device which cuts it into fibres of finite length and from which the cut fibres are continuously transported to an adjacent rod-forming device. A tow (2) of secondary cellulose acetate filaments is drawn through an air banding jet (4), stretched by passing between two spaced pairs of rollers (3, 6) of which the downstream pair (6) is driven at a faster speed than the other pair (3), passed through a second air banding jet 7, and sprayed in its band form with glyceryl triacetate. The sprayed tow band is then passed into a funnel 12 leading to a staple cutter 13. The cut fibres are pneumatically discharged by a fan 15, through a frustoconical wire mesh screen 20, under a tongue 45, and on to a pervious tape 22 of a rod forming device 20. The device 20 includes a suction chamber 43 underlying the first part of the upper run of the tape 22, and a steam heated block 24. The block 24 has a cylindrical bore which constrains the tape 22 to envelop the cut fibres into a rod 31, the ridge of fibres caused to protrude between the edges of the tape 22 being returned to the body of the rod 31 by a narrow blade within a ridge remover 41 before air cooling of the rod 31 within an enclosure 31. The cooled rod 31 is then cut off in normal manner, optionally after wrapping with paper in a garniture. The heatiing of the cut fibres in the block 24 accelerates the bonding action of the solvent plasticizer glyceryl triacetate. Another suitable plasticizer is triethylene glycol diacetate, but other bonding constituents such as fusible resins or fibres may be used. Other filamentary tow materials mentioned are polyethylene, polypropylene, cellulose triacetate, nylon and viscose. Paper fibres may be incorporated with the cut fibres by feeding them into the staple cutter 13.

Abstract: 1375488 Inverting SIEMENS AG 10 March 1972 [13 March 1971] 11428/72 Heading H2F In a pulse-width modulated inverter, control signals are formed in dependence on the points of intersection of a periodic reference signal r of frequency corresponding to that of the required output with at least two voltage levels a1, a2 adjustable in relation to the required output voltage Ust from the inverter (Fig. 2). As shown, levels a1, a2 are adjusted in such a way that the magnitude of one of said voltage levels a1 (or the difference between two of said levels a2-a1) first increases as the required output voltage Ust is increased and then becomes reduced or maintained constant so as to determine a minimum off period t min . The inverter may be used to control the speed and torque of an asynchronous motor by controlling the triggering times of a bridge of thyristors. By adjusting the magnitude and/or number of voltage level such as a1, a2 the number of on/off periods in each half cycle of the inverter output is determined. The discontinuous laws shown in Fig. 2 may be produced by means of five operational amplifiers (Fig. 3, not shown), resistors and diodes. The periodic reference signal r may have sine, sawtooth, triangular or trapezoidal form.
