Filed: 1920-11-08
Abstract: 174,769. British Thomson - Houston Co., Ltd., and Pearce, H. Nov. 8, 1920. Protective arrangements. - In a Merz-Price system of protection for apparatus and distribution lines, faults between phases are dealt with by connecting a point in the secondary circuit of one of the phase transformers to a corresponding point in the other through phase relays adapted to open the main switch. In the arrangement shown, the mid points of the middle transformer secondary winding are connected together through the relays 12, and only a single additional pilot wire 11 is necessary for dealing with faults between any two phases. Faults to earth are dealt with in the ordinary way by the relays 6 in the pilot wire connections 5 between the balanced transformers.

Title: Method and Apparatus for Forming a Web of Highly Parallelized Textile Fibers
IPC: D01G15/46
Filed: 1966-07-13
Abstract: 1,157,014. Parallelyzing fibres. FIELDCREST MILLS, Inc. 13 July, 1966 [20 Sept., 1965], No. 31547/66. Heading D1N. The fibres in a web W coming from the doffer 12 of a carding engine are parallelized by the web being drafted. The web is taken from doffer 12 by a roll 13 and then passes between adjacent drafting rollers 14, 15, the draft applied being 1.5 to 3 or higher the distance between the nip of rollers 14, 15 and the point where the web W leaves roll 13 is less than the average length of the staple fibres in the web so that the fibres are combed between the annular rings of garnett teeth on roll 13. A fixed or rotatable plain roll 25 is positioned beneath roll 13 to ensure that the web is embedded in the teeth. A rotary brush (27), Fig. 1, not shown, having bristles of e.g. wire or nylon engages the web on doffer 12 to assist in parallelizing the fibres; the surface speed of the brush is much greater than that of the doffer. The surface speed of doffer 12 may be 5-10% greater Than that of roll 13; the doffer may be rotated in the opposite direction to that shown. The leading face of the teeth 13a on roll 13 slope forwardly as in Fig. 3, not shown. Roller 14 has a cover 14a of natural of synthetic rubber or cork to engage the flutes of the lower roller; it may be weighted by its own weight or by other means and it may be driven independently or by its contact with roller 15. In Fig. 4, not shown, roller 25 of Fig. 2 is replaced by a larger diameter, garnett wire clothed roll rotated so that its surface closely adjacent roll 13 moves in the same direction as roll 13 and with the same speed. In Fig. 5, not shown, roll 13 rotates in the direction opposite to that shown in Fig. 2 and a conventional oscillating doffer comb is provided above roll 13 to assist in placing the web on the roll.

Filed: 1934-11-02
Abstract: 443,854. Cigarette-making machines. MAY, R. F., 9, Manor Road, Potters Bar, Middlesex. Nov. 2, 1934, No. 31563. [Class 130] To obviate any central hole or looseness in a spiral filter tip or like mouthpiece the tip is rolled, in the same direction as during its formation, under deforming pressure. A loose spiral 1a, produced from strip material 1 in a rolling unit 2, is placed between an intermittently rotated drum 3 and a curved member 4, and is deformed when a cam 5 moves the member 4 towards the drum 3. As the drum rotates the deformed filling is rolled in the same direction as during its formation, and the compact filling is received in a chamber 6 from which it is ejected by a plunger. In modified forms: (1) the curved member 4 is fixed adjacent the drum so that the filling is deformed during the rolling operation and the inlet end of the member 4 is diverted outwardly; (2) the loose spiral is produced by feeding strip material through a spiral former or draw plate; and (3) the spiral is rolled between an endless band and a straight member, or by two discs, drums or endless bands moving in opposite directions.

Abstract: 770,993. Endless belt conveyers. MAVOR & COULSON, Ltd. July 14, 1954 [Dec. 15, 1952], No. 31687/52. Class 78 (1). The endless belt conveyer which is driven on its return run has an assembly of three pulleys, each movable lengthwise of the conveyer to form the belt into extensible and contractible loops, two of which extend on opposite sides of the driving gear and control the ratio of the respective ingoing and outgoing tensions by means of a motion-multiplying gear connected between their pulleys, whilst the length of the third loop is controlled by a manual take-up gear acting on its pulley. As shown, the belt 10 passes at the end of its conveying run over a pulley 29, and extends in a loop 10a formed by a slidable pulley 11, around a driving pulley 30 and snub pulley 31, in a second loop 10b formed by a slidable pulley 12, and in a third loop 10c formed by a slidable pulley 13. Pulleys 11, 12, 13 are mounted for horizontal sliding on carriages 14, 15, 16 respectively running on tracks (not shown). At each side of the belt a rope 25 anchored at 36 passes around a pulley 22 on carriage 14 to the smaller pulley 33 of a differential pulley gear, the larger pulley 34 of which has a rope 26 connected to it which passes around a pulley 23 on carriage 15 to an anchorage 37. The ratio between the diameters of pulleys 33 and 34 determines the ratio of tensions T1, T2 of the loops 10a, 10b. A rope 27 anchored at 38 passes around a pulley 24 on carriage 16 to a winch 35. The driving motor for pulley 30 may be a regenerative electric motor whereby, when the conveyer is used on an incline and the load is being conveyed downhill, the motor acts as a brake.

Title: Manufacture of new polyamides
IPC: C08G69/34
Filed: 1965-07-27
Abstract: Thermoplastic polyamides are prepared by reacting (a) polymerized fatty acid mixture containing 95-100% of dimerized acid with (b) ethylene diamine; and (c) 2.5-10% of e -caprolactam at 180-250 DEG C.  The polymerized fatty acid mixture may be obtained by free radical or ionic polymerization of a saturated or mono- or poly-ethylenically or acetylenically unsaturated fatty acid, e.g. tall oil fatty acid, in the presence of a catalyst, e.g. alumina. The mixture of oligomers so formed may be distilled to isolate the dimer.  The acid may be replaced by an amide-forming derivative, e.g. its methyl or ethyl acid ester.  The reaction mixture may contain hexamethylene diamine in an amount such that its equivalence ratio to ethylene diamine is 1:1-9.  After the polymerization the eliminated water may be removed at 15-20 mm. Hg.  The product may be up to 30% soluble in propanol, isopropanol, butanol, ethanol and mixtures of isopropanol with benzines and toluene, the products being useful as adhesives for metal, wood, leather and synthetic materials.  In examples a phenoplast resin is added to the polymerization mixture as an antioxidant.

Title: Improvements in hinges
Inventor: HINDLEY JOHN PETER
IPC: E05D3/06
Filed: 1965-07-29
Abstract: 1,112,979. Hinges. GENERAL STEEL PRODUCTS Inc. 29 July, 1965, No. 32449/65. Heading E2F. [Also in Division A4] A hinge for a sofa convertible to a bed is attached thereto by links 19, 20 and comprises two plates 16, 27 having a latch 32 coupled therebetween said latch hanging freely in the bed position as shown, and being jammed by an abutment 29 sliding in an arcuate slot 30 in the back plate 16 in the seat position. To convert the sofa from the bed to the seat position, a seat frame 14 is raised through 90‹ relative to a back frame 12 about a pivot point 25 in the direction of arrow 'a' when the abutment 29 on the seat hinge plate 27 strikes the end 31 of the slot 30 in the back hinge plate 16, said abutment also locating a notch 37 in the latch 32 suspended freely from a pin 33. The raised seat frame 14 is then pushed downwardly so that the latch moves from an extended position to a retracted position with respect to the pin 33 by reason of an arcuate slot 34, Fig. 5B (not shown), while the frames are rotated relative to one another until the abutment reaches a point (41), Fig. 3B (not shown) in the slot B30 when the latch is prevented from rotating further about its coupling pin 33. The frames then pivot together subtending a constant angle until the seat frame contacts the sofa base 15. To convert from the seat to the bed position, the seat is raised in the direction of the arrow 'b' in Fig. 3B (not shown) to an intermediate position as shown in Fig. 5B (not shown), when the back frame rests on the base (15), which with further upward movement of frame 14 causes the retracted latch 32 to pivot until the abutment 29 reaches the end 31 of slot 30, when the latch falls freely to be suspended under gravity, and the seat frame may be pushed downwardly to rest horizontally on the base 15. A further embodiment comprising a "dropback" bed is described in which the seat and back frames 14, 12 are reversed with the latter being affixed to the base 15 while pivotal links 19, 20 are removed or made inoperative.

Abstract: 649,242. Determining physical qualities of materials. FIELDEN (ELECTRONICS), Ltd., and FIELDEN, J. E. Dec. 16, 1948, No. 32547. [Class 37] Apparatus for determining the moisture content of a length of material comprises an electrode located close to the surface of the material so that its capacity depends on the amount of moisture present in the material, the electrode being associated with a capacitysensitive relay. As shown, the electrode a is connected into a Hartley oscillator circuit through a screened coaxial lead, the oscillating voltage being rectified by a diode V2, and fed to a thyratron V3, a proportion of the rectified voltage also being taken to another thyratron V4. Thus, an increase in capacity of electrode a reduces the degree of oscillation and the rectified voltage from diode V2, so that thyratrons V4, V3 respond in that order, and relays f, g connected in their anode leads are energized to operate indicating or control circuits corresponding to different degrees of moisture in the material.

Title: Improvements in shock-absorbing struts for aircraft undercarriages
IPC: B64C25/60
Filed: 1935-11-23
Abstract: 469,473. Shock-absorbers. FAUDI, F. Nov. 23, 1935, No. 32548. [Class 108 (iii)] In a shock-absorbing strut for aircraft undercarriages employing highly-compressed air as the shock-absorbing medium, in order to enable the strut to respond to shocks occurring when the aircraft is moving on the ground in an unloaded or lightly - loaded condition, a spring is arranged in the strut to oppose the force exerted by the compressed air. As shown, the strut comprises an outer cylinder B, connected to the aircraft, in which slides a piston A having a tubular rod D adapted to carry a landing-wheel, skid, float, &c., the spring E being arranged in the annular space J between the cylinder and rod and abutting at its upper end the piston A and at its lower end packing C which closes the annular space J. On extension of the strut the compressed air in chamber G acts as a damping medium. For this purpose openings H in the piston are controlled by a spring-pressed, apertured valve F so that when the strut is compressed the valve F opens and air flows into the annular space J, while, when the strut is extended the valve F is closed and the air passes back to the chamber G only through the restricted apertures in the valve. When the aircraft is being flown, the piston may abut a stop before the spring E is compressed sufficiently to counter - balance the pressure of the compressed air. The Specification contains a certain amount of theoretical discussion illustrated by graphs. Specifications 25033/06 and 28283/08, [both in Class 108], are referred to.

Title: Improvements in or relating to welding
IPC: B23K11/24
Filed: 1935-11-25
Abstract: 461,767. Electric welding. PRESSED STEEL CO., Ltd., and SIMMIE, W. T. Nov. 25, 1935, No. 32572. [Class 83 (iv)] In a fluid-pressure electric-resistance welding machine, the pressure is controlled by a valve actuated firstly to bring the electrodes together under predetermined pressure, then to initiate the flow of welding current, whereupon the pressure is reduced and on cessation of the welding current the pressure is restored to its original value. When button P is pressed a relay S is first energized through the secondary of a step-down transformer W connected across lines L1 and L2 and closes contacts s<1>, s<2>. A relay R is thus energized via conductors 13-16 to close a switch r<1> controlled by a dashpot d. Consequently relay V is energized to close contacts v<1> which thus causes a solenoid A to be energized to raise the valve X and allow fluid pressure to be supplied to the welding gun 21 via line p. The pressure builds up and brings electrodes 1, 2 together. Leakage of air over line w then closes switch band the coil M of the welding circuit contactor C is thus energized through conductors 18, 19, safety switch h, conductors 20, 21, switch b, conductor 22, switch e<1> conductor 23, switch s<1> and conductor 13. When contactor C is closed, the circuit of coil M is maintained by a locking circuit through switch e and the circuit over the push button switch is maintained through switch f, so that this circuit is not interrupted after the push button is released. Closing of contactor C also causes coil F of auxiliary air valve Y to be energized and the valve is raised to allow pressure from line p to be supplied to the lower end of the cylinder through a throttle valve G so as to reduce the pressure on the electrodes. When welding current flows a transformer t picks up a time delay relay D to close switch d<1> and thus relay E is energized via conductors 13, 23, 26 and 18. Switch e<2>is thus closed to complete a locking circuit for coil E and switch e<1> is opened to de-energize coil M and thus cut off the welding current. At the same time coil F is de-energized to lower valve Y and put lower end of cylinder into communication with the atmosphere. Pressure thus builds up again in the upper end of cylinder for a time determined by the dashpot controlled switch r<1>. When this switch opens the coil A is de-energized and the valve closes the air inlet p and connects cylinder at n to exhaust. Electrode 1 is returned by a spring.
