Title: Barrow
IPC: B62B1/16
Filed: 1975-11-26
Abstract: 1498088 Wheel barrows D HARRIS and J HARRIS 26 Nov 1975 [11 Dec 1974] 48634/75 Heading B7B In a wheel barrow a hopper 14 and a handle 15 are pivotally mounted about transverse horizontal axes to a wheeled frame 11. The pivot axis of the hopper is chosen to provide an anticlockwise moment when the frame is horizontal. A catch member 19 on the frame engages a stop 20 on the hopper which thus limits anticlockwise movement of the hopper relative to the frame. A lever 17 on the handle withdraws the catch 19 against spring bias to allow pivoting of the hopper. Pawl members 21 on the frame have notches 25 which are engaged by spring biased dog members 24 operated from a lever 22 on the handle for selectively locking the handle relative to the frame.

An index for a telephone subscriber comprises a container 1 having a tray 2 slidably mounted therein which houses a stack of index cards 4, each card having an associated selection member which, when operated to select a card, is arranged so that as the tray 2 is withdrawn from the container 1 the selected card and any others below it are withdrawn with the tray, whilst any others above the selected card are retained by magnetic attraction in the container. Each card 4 has a U-shaped metal member (41, Figs. 7 and 8) clamped on its rear edge, and a permanent magnet 15 is arranged on the inside of the container to hold back all the cards not engaged by the selector. Card selection is made by a group of selectors 24, one selector for each card, arranged opposite an alphabetical index (13, Figs. 1 and 2). Each selector 24 is part of a bell-crank pivoted on a cross-shaft 28, the other end 26 of the crank having an upwardly-extending pin 27 adapted to engage perforations (42) in the front ends of the cards 4, and a leaf spring 30 on each selector holds it in a forwardly-inclined position. The perforations (42) in the cards 4 are so arranged that there is one only in the top card, two in the next, and so on. The bottom card has as many perforations (42) as there are selectors 24, i.e. twelve in the arrangement shown. With the tray 2 in the closed position and a selector 24 pulled towards the front wall 21 of the tray, the corresponding pin 27 of the selector will pass through all the cards beneath the selected card, and the selected card, and when the tray 2 is withdrawn, the pin 27 will pull these cards away from the permanent magnet 15. The tray 2 can only be withdrawn to a position limited by a stop arrangement (18, 19, Fig. 4), in which position the rear ends of the withdrawn cards support the front ends of the cards retained by the magnet 15. The container 1 has rubber feet 10, and the upper face is roughened to hold a telephone set (A, Fig. 1) in position thereon. The container 1, tray 2, and all the accessories, apart from the magnet 15 and the metal pieces (41) on the cards, can be made of plastics material.

Patent GB-1092656-A (GB)
Title: Process for the production of purified quartz sand
IPC: F16K39/02
Filed: 1964-12-07
Abstract: Purified quartz sand is produced from quartzose crude sand containing non-quartzose particles as impurities by washing particles of diameter 0.1-0.3 mm. at room temperature or above, e.g. 40-120 DEG C., at atmospheric or superatmospheric pressure with an aqueous medium of pH 7.0-11.0, preferably 9.0 to 9.5, containing a wetting agent (e.g. alkyl-benzene sulphonates or ethylene oxide addition polymers) and when necessary, a compound capable of forming complex salts with the cations present in the impurities (e.g. iron, calcium, magnesium, manganese, aluminium, titanium, chromium) such as monobasic or polybasic acids having one or more hydroxyl or nitrogen-containing groups, e.g. salicylic acid, dihydroxymaleic acid, hydroxamic acids, pyrophosphoric acid, tartanic and thioglycollic acids, and the washed sand particles are subjected to an electrostatic or electromagnetic field (e.g. of strength >20 kilogauss at an air gap of 0.5-5.0 mm) to separate quartzone particles from non-quartzose.  It is necessary to use such complex-forming compounds when the impurities are very firmly adhered to the particles. The ratio by weight of aqueous medium to crude sand may be \sF2:1.  The washing action may be enhanced by producing pressure waves of frequency >20 kc/s., preferably >80 kc/s., and preferably of intensity >0.5 watts/sq. cm. causing implosions on the surfaces of the particles. Spark discharges of energy 500-10,000 watt-secs. may also be used.  The crude sand may also be washed preliminarily with water rendered alkaline of pH 7.0-11.0, which may be repeated one or more times.  Particles of diameter 0.1-0.3 mm. are obtained from natural quartzone crude sand by separating particles of diameter < 0.1 mm. and > 1.0 mm., and separating those of diameter 0.1 to 0.3 mm. from the resulting fraction by hydroclassification in the water used for the preliminary washings.  The particles of diameter 0.3 mm. to 1.00 mm. may be disintegrated to give more particles of diameter 0.1 to 0.3 mm., all of which may be further graded, e.g. into fractions having particle sizes of 0.1 to 0.2 mm. and 0.2 to 0.3 mm.

Abstract: 1,181,085. Disc brakes. KELSEY-HAYES CO. 13 Nov., 1967 [13 Feb., 1967], No. 51562/67. Heading F2E. In a disc brake having a fluid motor part 55 of a caliper 47 slidable on pins 87, 89 which are held by a torque plate 46, each pin 87, 89 has an abutment 114 and a resilient means 116 is positioned between the fluid motor part 55 and the abutment 114 so as to return the caliper to a brake release position when the braking is completed. On braking the fluid motor part 55 moves to the right and the resilient grommet 116 of elastomeric material is compressed; further movement of the caliper to the right causes the pins 87, 89 to slide in elastomeric grommets 107 mounted in arms 71 (73, Fig. 2 not shown), of the torque plate. This moves the left brake pad assembly 81, Fig. 3, into contact with the disc 21, the other pad assembly 75 is moved directly by a piston 63. When the brake is released seal 233 acts to restore the piston and the caliper is restored by the elastomeric rings, 116 which move the caliper to the left to provide the release position. The movement of the caliper to the left is limited by a washer 117 fixed to the pin 89. The caliper 47 is guided by edges 206 of axially extending flanges, one of which is shown at 193. The fluid motor part 55 of the caliper 47 is secured to the torque plate 46 by a flexible strap 155, 171, 173 which resists movement of the caliper in any direction except perpendicular to the disc. The backing plates of the pad assemblies (Figs. 4 and 5, not shown), have projections (119, 121, 127, 129) with oval holes (123, 125, 131, 133) which locate them on the pins 87, 89.
