Title: Improvements in or relating to Article-Feeding Apparatus.
IPC: B65G51/02
Filed: 1966-06-15
Abstract: 1,162,542. Shoots; pneumatic conveyers. CLYDE CORP. 15 June, 1966 [29 June, 1965], No. 26587/66. Headings B8A and B8S. Apparatus for feeding articles from a source to a delivery point comprises a track for receiving articles from the source, a shuttle 58 movable laterally of the track and having an opening 104 which in one position receives an article from the track and in another position delivers the article to a guideway 108 extending downwardly to a flexible tube leading to the delivery point, a gate 60 movable laterally of the guideway 108 between positions in which the guideway is respectively open and closed, the shuttle 58 and the gate 60 being operated so that the opening 104 is aligned with the guideway 108 when the latter is closed by the gate 60, and means for introducing air under pressure through an opening 128 when the guideway is closed for propelling an article through the tube. The track leads from a hopper described as vibratory but which may be rotary or oscillating and the tack is formed by a flexible tube so that it vibrates with the hopper. The shuttle 58 and the gate 60 are secured to a cross-head 88 which is connected to a pneumatically operated, spring-loaded piston 82. The gate 60 has an opening 120 through which the articles fall into the tube leading to the delivery point. Air passes to the opening 128 through passageways 122, 124, 126, a valve pin 132 being spring-loaded into engagement with the crosshead 88 so as to follow the latter to control the air flow to the opening 128. A screw 130 adjustably controls the amount of air passing. The shuttle 58 has a top recessed part (140), Fig. 10 (not shown), so that the edge of the opening 104 does not engage the article above that received in the opening and to slightly joggle the articles in the track. Controls are provided at the delivery point, e.g. at a tool such as a nut runner, which can be actuated to control the air to the piston 82 so that an article is delivered upon demand. The surfaces defining the guideway 108 have a closer tolerance with respect to the articles, to prevent tilting thereof, than those of the tube leading to the delivery point which although sufficient to keep the articles correctly orientated permits the tube to be bent, the greater tolerance also preventing excess acceleration of the articles in the tube by facilitating escape of air past articles in the tube.

Abstract: 1326679 Levelling tow TURBO MACHINE CO 19 April 1971 [10 Aug 1970 26684/71 Heading D1F A process for improving the levelness of a moving band of filamentary tow comprises (a) advancing the tow while under a tension insufficient to cause filament breakage (b) laterally separating some of the filaments with respect to other in the tow band whilst increasing the tension of the band, (c) decreasing the tension in the filaments, (d) making lateral separations of the filaments in the tow band whilst increasing the tension in an amount insufficient to cause breakage. The above steps are repeated intermittently. The process may be carried out in an apparatus comprising a plurality of rods moving in paths in a direction to cause them to engage the tow, each rod having a plurality of V-grooves on its surface, each rod intermittently engaging a face of the tow with its grooved surface and dividing the tow into a plurality of bundles and laterally displacing the filaments thereof and diverting the tow from its path, the grooves on each rod being out of phase with the grooves on the preceding and the succeeding rod. A suitable apparatus is shown in Fig. 1 and comprises a creel frame 10, guide bars 12, 14, 16, 18, 20 and 22, and beaters 26 and 28. Each beater is provided with rods each having a grooved surface (if parts 58, 59 and 60 of Fig. 2 (not shown)). The beaters rotate in the opposite direction to that of the tow 24 and the grooved surfaces engage the tow and separate it into a plurality of filament bundles. The rods are arranged so that the grooves are transversely out of phase (Fig. 4, not shown). The lateral separation of the tow may also be achieved by using a plurality of air jets located transversely across the tow band. or by penetrating the tow band with blade having V-shaped sharp-toothed serrations.

Title: Improvements in and relating to the non-destructive testing of solid bodies
Inventor: WILSON ROBERT
IPC: G01N29/28
Filed: 1950-11-02
Abstract: 708,253. Ultrasonic wave couplings. KELVIN & HUGHES, Ltd. Nov. 1, 1951 [Nov. 2, 1950], No. 26802/50. Class 40 (4) [Also in Group XXXVIII]  A transducer is coupled to a solid under test by chlorinated rubber paint or other setting liquid which, when dry, has a specific acoustic impedance less than that of water. The paint may be applied directly to the solid to be tested and allowed to dry or alternatively, may be applied to a silk or nylon fibre which, when dry, is squeegeed on to the solid. To prepare nylon fabric, the fabric is stretched across a frame and is secured by adhesive. A coating of thinners is sprayed on the fabric and is followed by coatings of paint thinned to a prescribed' viscosity. The fabric is stoved for 5 minutes at 75‹-80‹C. after each coating of paint and the process is continued until the thickness of the paint is one half wavelength (0.025 in.) or an integral number of half wavelengths at the operating frequency (2.5 mc/s.) When the fabric is used, a small quantity of methylated spirit of paraffin or of paste made of flour and water is first applied to the solid to be tested. Testing.-When the bonding between a sheet 10 of white metal and a sheet 11 of steel is tested, chlorinated rubber paint is applied on layers 12, 13, and allowed to dry.. The paint is smeared with oil or grease and the piezoelectric transducers 15, 16 are brought into engagement with the paint. A number of similartesting operations are described (see Group XXXVIII).
Patent GB-268851-A (GB)
Abstract: 268,851. Lefebure, V. Dec. 7, 1925. Compound tiles; ornamenting tiles.-Decorated tiles or slabs are formed from a plastic mass obtained by mixing an alkaline silicate, colloidal silicic acid, or silica with an oxide (e.g. of zinc, iron, tin, tungsten, or phosphorous), or a salt (e.g. zinc chloride or ferric phosphate), one or both of the ingredients being used in a syrupy or colloidal form. Substances capable of taking up water, such as Portland cement or zinc or magnesium chloride, and substances capable of combining with excess alkali, such as calcium fluoride, magnesia, aluminium hydroxide, or a soluble silico-fluoride may be added to the mixture, and inert fillers such as asbestos, silica, and colouring matters may also be added. The resulting plastic mass is formed into sheets, cut or moulded to the desired shape, and hardened by heating to a temperature below 300‹ C. The sheet before hardening may be cemented to a rigid backing such as asbestos cement by means of an adhesive, which may be either synthetic resin or a soluble silicate and metallic oxide mixture. Marbled effects are obtained by calendering partly mixed masses of different colours.

Title: Improvements relating to turn-off arrangements for direct current switching circuits
Inventor: EASTOP ROBERT HENRY
IPC: H02M3/135
Filed: 1963-07-08
Abstract: 1,020,590. Semi-conductor switching circuits. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. June 29, 1964 [July 8, 1963], No. 26902/63. Heading H3T. In a direct current switching circuit utilizing a semi-conductor controlled rectifier (SCR) the SCR is rendered non-conductive by application of reverse voltage from a capacitor 3, the capacitor being charged via a unilaterally conductive device 6 from the energy stored in an inductor 4 connectable across the supply. As shown in Fig. 5, SCR2 is turned on by means not shown, when it is required to connect an inductive load, shunted by a free-wheeling diode 22, across a D.C. supply Es. SCR2 is turned off by triggering SCR5 which applies a reverse voltage from capacitor 3. Capacitor 3 is recharged via diode 6 by the energy available in winding 21 when the blocking oscillator transistor 10 becomes non-conductive. The blocking oscillator 10 may be free-running or, as in Figs. 2, 3 (not shown) may be monostable, triggered by an external pulse after triggering SCR5, the duration of its pulse being limited by core or transistor saturation. Fig. 4 shows an arrangement in which the load 7 is connected to the supply Es by triggering SCR2, which is in turn, turned off by triggering SCR5 which applies a reverse voltage from capacitor 3, capacitor 3 being recharged via diode 6 from the energy stored in inductor 4 when a further SCR15 is turned off. SCR's 15, 16 are normally non-conductive, 15 being turned on at the same time as SCR5 by pulses from an oscillator so that a linear rise of current occurs in inductor 4 and transformer 13, whilst capacitors 18, 19 charge via resistor 12 and diode 20. When the core of transformer 13 saturates, SCR16 is turned on by the voltage across capacitor 19, so that the commutating capacitor 18 turns off SCR15. Capacitor 3 is recharged via diode 6 from the energy in inductor 4, SCR16 being turned off by the collapse of voltage across 4 being passed via capacitor 18.

In a handbrake lever mechanism for vehicles in which the brakes may, if necessary, be applied by repeated strokes of the handbrake lever, an actuating pawl 32 is associated with the brake lever 30 which is normally urged into engagement with the teeth 34 of a rack 35 adapted to move axially in the direction for applying the brake, but in the fully released position illustrated in Fig. 3 is withdrawn from engagement with the teeth of the rack, a holding pawl 39, adapted to be released by hand control 41 and flexible cable connection 42, being provided normally to engage the rack and hold it against movement in the brake releasing direction. In the fully released position of lever 30 illustrated in Fig. 3, the tail 45 of pawl 32 engages a fixed abutment 44 on fixed back plate 37 and the tip of pawl 32 is lifted out of engagement with rack teeth 34. Pulling the hand grip of the lever 30 upwards releases the pawl from abutment 44 and allows its tip to engage ratchet teeth 34 upon further upward movement of the brake lever 30 the rack is moved to the right to apply the brake and is restrained against return movement by the holding pawl 39 while the lever 30 is returned for a further stroke to complete the application of the brake. The brake may be released gradually under the control of the driver by taking the load with the brake lever 30 while the holding pawl is withdrawn by squeezing the hand control 41. The brake may be released in this way to a sufficient extent to release the brake sufficiently for starting off and once the engine has control of the movement of the vehicle the brake lever may be moved to the fully released position. A further embodiment is described and illustrated in the Specification wherein the pawls may be opposed to engage separate ratchet teeth on opposite sides of the rack.
