Title: Intermittent inductive train control system
IPC: B61L3/12
Filed: 1925-04-06
Abstract: 254,035. Howe, W. K. April 6, 1925. Fluid-pressure.-A modified control of the usual engineer's valve is used in an automatic braking system. A casing 30 with a cylindrical extension 31 is serured by a flange 32 in place of the cover plate of the usual valve casing 33. The usual rotary valve. 36 extends into the casing and has a square recess which receives the square lower end of a stem 38 rotatable in a bearing formed in a partition 34 and having a flange 39 held fluid-tight against the partition by air-pressure and by a spring 41. A disc secured to the stem 38 has projections 53, 64, 67. Below this disc and rotatable on the spindle is a toothed sector 45 engaged by a rack 46 secured to .a piston 49 in cylinder 31, normally urged to the right, Fig. 3, by a spring 50. In this normal position, sector 45 leaves the disc free, but when piston 49 and rack 46 move to the left, the edge of sector 45 engages projection 53 and rotates the valve anti-clockwise to brake-applying position. The usual control handle 71 is carried by a spindle 60 rotatable on the upper end of stem 38 and tethered to projection 67 by a spring 65. A radial pin 63 on spindle 60 is adapted to engage projection 64 so that an anticlockwise movement of the handle positively moves the valve to braking position, but when the handle is held or moved in clockwise direction the spring connection 65 is not strong enough to hold off an automatic application affected by the rack 46. The normally energized device E.P.V. holds up a stem common to two valves 85, 86, the former normally seated and the latter open. Under these conditions the right hand end of cylinder 31 is vented to atmosphere through pipe 88 and venthole 89. When the device E.P.V. is de-energized valve 85 opens and valve 86 closes. Air pressure is then supplied through pipe 87, valve 85 and pipe 88 to cylinder 31, moving piston 49 to the left against the action of spring 50, and effecting a brake-application through rack 46 and sector 45.

Title: Leather substitute and process of making the same
IPC: D06N3/00
Filed: 1926-04-07
Abstract: 276,392. Respro Inc., and Abbott, R. K. April 7, 1926. Fabrics composed of fibrous materials agglutinated by adhesives; fabrics with multiple superposed coatings; treatment prior to coating. -A leather substitute or like material is made by impregnating a sheet of unwoven fibrous material of loose or open texture with cementitious material such as rubber, applying thereto a surface coating of such consistency that the previously coated fibres at or near the surface of the sheet are enclosed in the surface coating, allowing the coating to set, and then applying pressure. Preferably the surface coating material is such that it wets the original impregnant. A loosely constructed sheet of unwoven fibres such as cotton batting or wadding, is first impregnated with a viscid material such as rubber in a solvent, this being intruded into the sheet as described in Specification 216,682. The material is then allowed to recover part of its original thickness so that air acts on the rubber and renders it more adhesive. A priming or base coat of dressing, such as a viscous or pasty solution or mixture containing a cellulose derivative of such consistency that it enters the pores of the material and envelopes the fibres at or near the, surface of the material, is then applied. Preferably the coating composition is one of which the solvent is capable of wetting contact with the adhesive constituent of the eementitious material already impregnating the sheet. The solvent for the coating material may be miscible with and serve as a.'softener for the oementitious material, e.g..if the original impregnant is rubber dissolved in naphtha, the dressing may be nitro-cellulose dissolved in amyl or ethyl acetate, with or without benzol, or cellulose acetate dissolved in acetone. Successive coats of a surface coating may be applied over the base coat, each being allowed to dry to a tacky state before applying the next, and the material calendered. Or the material may be calendered before applying the finishing coats. The, material may be finally embossed. For the base coating nitrated cotton dissolve 1 in solvent such as ethyl acetate in the proportion of 16 ozs to one gallon of solvent, together with softeners, may be used, thinned with solvent to the desired viscosity. For the superposed coatings, castor oil to the amount of 10 per cent of the weight of the solution is added, with pigment, and the whole thinned with ethyl acetate. When a waxy finish is desired, a varnish gum such as shellac, and a hard wax such as carnauba wax, in solution with borax or soap, or both, may be used for the coating. Perfume may be added.

Abstract: 331,589. Traver, H. G. April 5, 1929. Divided on 331,577. Railways and tracks for recreation.-Relates to cars for use with an amusement railway as described in the original Specification 331,577, which normally urge passengers to upright seated position and are adapted to allow them to assume a backward reclining position. Electric shocking means are provided and the front car wheels are mounted to pivot about a longitudinal axis to adapt the car to the undulating track. The car comprises a body 10, front 11, hand rails 13, seat 20, the seat back 21 being fitted at each side with a side wing 22 having an arm 26. The arms 26 have notches 29 normally engaged by a transverse bar 27, Fig. 1, which at various points of the track is tripped by a lever 32 engaging members 31 on the track to be released from the notches, the weight of the passengers then causing the seat back 21 to rock backwards to the position shown in Fig. 2 when both the springs 34 and 24 return the seat-back to the normal back Supporting position. The car wheels 14 are cartied in U-shaped brackets, those at the rear being integral with the body 10, while the front brackets 16<1> are carried on a truck 17 pivotally connected by means of longitudinal pins 18 to brackets 19 on the body 10. An electric contact below the car engages at certain portions of the track a live rail through the seat 20 to give passengers a shock, and spring pawls 42 engaging ratchets 45 at uptrack portions of the rails to prevent running backwards may be caused to make a clattering noise at other portions of the track by means of similar ratchets. Arms 37 having flanged ends 39 running under the projecting portions 38 of the track prevent the cars jumping the track.

Title: Production of phenol/formaldehyde resins
IPC: C08G8/12
Filed: 1970-02-26
Abstract: 1,248,354. Phenolic resin. MONSANTO AUSTRALIA Ltd. 26 Feb., 1970 [27 Feb., 1969], No. 9389/70. Headings C3P and C3R. A process for the production of an alkyl- or aryl-substituted phenol-formaldehyde resin comprises heating a p-alkyl or p-aryl phenol with formaldehyde in the presence of an inorganic alkaline catalyst and in a heterogeneous medium comprising an aqueous phase and a water-immiscible phase to form a 2-methylol or 2,6-dimethylol derivative of the phenol and subsequently etherifying this to produce the resin free from catalyst by (a) heating the methylol derivative in the water immiscible phase, (b) neutralizing the catalyst to form a salt in the aqueous phase and (c) separating the phases. Steps (a), (b) and (c) may be performed in any order. Where the phases are separated before the resin is formed, the water of reaction produced during the resin-forming step may be removed by azeotropic distillation. Some of the reaction solvent may also be distilled off. The phenol may be p-tert-butyl phenol, p-phenyl phenol, p-cumyl phenol or p-isopropyl phenol. The formaldehyde may be used as formalin or an aqueous methanolic solution. It may all be added at the start of reaction or added portionwise during the reaction. The alkaline catalyst may be NaOH, KOH or Na 2 CO 3 ; it, too, may be added before or during the reaction. The water-immiscible liquid may be toluene, benzene or butyl acetate. In forming the methylol compound the reactants may be heated under reflux. Afterwards the further heating to form the resin may be carried on without a break in the reaction sequence. The inorganic alkaline catalyst may be neutralized by an aqueous solution of H 3 PO 4 , H 2 SO 4  or oxalic acid. The resin product may be a liquid or solid. It may further be reacted with a chelating agent, e.g. MgO, in an organic solvent. In Example 7, a neoprene adhesive is formed by adding to a product of the invention a composition comprising neoprene, toluene, ZnO and MgO.

Title: Improvements in automatic machines for countersinking nut blanks
IPC: B23G9/00
Filed: 1928-03-29
Abstract: 312,440. Barlow, H. J., Moore, T., and Smith, W. H. March 29, 1928. Nuts. - A machine for countersinking nut blanks comprises a carrier for feeding the blanks which are placed one behind the other and moved forward in the carrier by pressure applied to the row so that the leading blanks are placed successively in countersinking position. The blanks are threaded by hand on a wire 2 extending from the rear of a grooved shoot 1 through a curved guide 3 the blanks being turned so as to enter the shoot with their faces in line by a threaded barrel shaped roller 4 rotated by a belt 5. The row of blanks in the shoot is pressed forward by a weight pressed bar 6 moved back from time to time. The blanks are pushed one by one from the end of the shoot by a lever operated bar 21 into the space 11 between outer and inner rings 9, 10 which are rotated at the same speed but are arranged eccentrically so that the space 11 varies in width, causing the nuts to be gripped in the narrow part and carried round to the countersinking tools 7, 8. The outer ring 9 of the carrier is mounted on three rollers 12 themselves mounted on eccentrics 13 for adjusting the position of the ring 9. The pressure of the drill 7 on the nuts is taken by a disc 17 supported by three rollers 18 mounted on the ring 9 and held stationary by a stay 17<a>; the other side of the space 11 is covered by an annular plate 20 which takes the pressure of the other drill 8 on the nuts. The drill spindles 26, 27 are rotated by belts 28, 29 and moved towards and from the nuts by levers 30 operated by rods 31 and eccentrics 32. The rear drill 8 countersinks the last nut but one and the drill 7 the last one in the rotation carrier, the last nut being positioned against a shoulder 33 on an ejector lever 34 which projects into the carrier groove 11 and is moved forward to eject the nut when the drill 7 retires. For this movement the ejector lever 34 is connected to a bar 39 with a catch 38 engaged by a nose 37 on a bar 36 connected to the actuating lever 30 of the spindle of the drill 7; a spring 40 returns the ejector lever at the end of its forward movement.

Title: Improvements relating to electric switches particularly for control systems of internal combustion engines
IPC: F02N11/08
Filed: 1933-11-20
Abstract: 434,082. Actuation of switches. DELCO-REMY CORPORATION, 329, East 1st Street, Dayton, Ohio, U.S.A.-(Assignees of Dyer, J. B.) Nov. 20, 1933, No. 9475/35. Convention date, Jan. 28, 1933. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 22, 1934.] Divided out of 433,937. [Class 38 (v)] A switch for use in controlling the starting motor of an automobile engine comprises an operating lever 84 connected to a short spindle 242 journalled in an insulating disc 212 and having at its end a driving member 256 formed with two axially extending driving lugs 258. Slidable in the spindle 242 is a spindle 262 supported at its other end by a diaphragm 220. An insulating disc 270 is rotatably mounted on the spindle 262 and carries a contact ring 272 having raised contact projections adapted, on certain positions, to engage fixed contacts, not shown, on the disc 212. The contact carrying disc 270 has axially projecting lugs 288 which, in the position shown, engage between the driving lugs 258 and are held in this position by a coil spring 300, one end of which is attached to the casing and the other end to the disc 270. In operation, the arm 84 is rotated when the accelerator of a car is depressed and the contact ring is rotated to complete the starter circuit. When the engine starts, the suction of the intake manifold, applied through nipple 230 moves diaphragm 220 to the right against the action of springs 240 and 300, thus moving the disc 270 and contact ring to the right to break the circuit. The lugs 288 are also disengaged from the driving lugs 258 and the contact disc is rotated to the original position by spring 300. If now the engine suction is reduced due to a wide open throttle and the diaphragm moves to the left, the lugs 288 engage on the ends of lugs 258 and so contact cannot be made unless the accelerator is lifted. This ensures that the switch cannot be operated while the engine is running.

Title: Hoist and safety mechanism therefor
Inventor: CARROLL CHARLES
IPC: B66D3/14
Filed: 1956-03-27
Abstract: 805,898. Chain hoists. DUFF-NORTON CO. March 27, 1956, No. 9532/56. Class 78 (5). A chain hoist has its load sheave 14 fixed on shaft 16 and driven through ratchet-wheel 21 by an oscillating handle 43 connected to shaft 38, the drive passing from said shaft 38, via links 35, link 34 and arms 28, the latter carrying load pawl 25 which drives said ratchet wheel. A holding pawl 26 is also provided and the engagement of the pawls is governed by reversing ring 45 to permit falling or lifting of the load or the freeing of the chain. This is done by cams 47, 49 which are positioned on the said reversing ring 45 and which respectively engage pins 27A and 50 on the respective pawls, the ring being biased by spring 51 and manually positioned by handle 56 which causes engagement of cam 54 with arm 57 on the reversing ring. Operation.-In raising the load (Fig. 4) both pawls engage the ratchet wheel, the oscillating handle causing pawl 25 alternately to engage the ratchet wheel and to ride freely over said wheel whilst pawl 26 prevents the fall of the load. In lowering the load, cam 54 is positioned by handle 56 as in Fig. 5. This permits ring 45 to raise pawl 26 from engagement with the ratchet wheel, the oscillation of handle 43 permitting pawl 25 to move clockwise as the load descends till said pawl 25 engages ring 45 at cam 49 so as to move the ring, the movement of the ring allowing pawl 26 to engage whilst the pawl 25 disengages from the ratchet wheel to permit the operator to return the oscillating handle anticlockwise to recommence another lowering movement. Free chaining.-This is permitted by handle 69 (Fig. 3) which, through cam 68, positions lever 60 pivoted at 61 so that, in the position shown, lever 60 engages pin 50 mounted on pawl- 25 to throw the latter clear of the ratchet wheel 21. At the same time the operator positions (by handle 56) the reversing ring so that its cam 47 lifts free the holding pawl 26 from the said ratchet wheel. Safety device 54A for preventing descent of load if, during load-descending operation the handle 43 should fly up clockwise out of the operator's grasp (Figs. 3 and 7). The spring 54A controls the axial jutting-out position of cam 54 in which normally the part 54 engages arm 57 to thus position ring 45. However, when the operator is operating the handle 43, if the handle should slip and fly backwards (i.e. should fly back clockwise), then the impact of lever 34 upon bumper pin 67 will depress the latter and permit said lever 34 to swing through a greater-than-normal arc. This arc causes pin 50 to engage cam 49 and thus to rotate ring 45 so that arm 57 moves past cam 54, thus permitting spring 54A to push out said cam so that part 54B holds the arm in its past-the-normal position. In this position of ring 45, both pawls look the ratchet wheel (and thus, the load) safely.
