Title: Improvements in or relating to freight binding devices
IPC: B65B27/00
Filed: 1965-07-22
Abstract: 1,117,448. Packaging. A. T. KEARNEY PERSONNEL SERVICES. 22 July, 1965 [22 July, 1964], No. 31316/65. Heading B8C. A device for binding freight comprises a base member, wrapper means secured to one edge only of the base, and releasable connecting means for holding the wrapper means under tension around the freight. The wrapper means is long enough to extend at least partially around the freight lying on the base, and is flexible about a plurality of vertical axes so that the wrapper can be adapted to wrap around freight of varying dimensions which may project beyond those sides of the base not connected to the wrapper. As described, Fig. 1, the wrapper comprises a polypropylene sheet 16 scored at 22, 24 to form vertical hinges. The base 12 has planks 14 for inserting the tines of a fork-lift truck. The connecting means comprise elastic cords 26, 28, securable as shown. The wrapping means may consist of vertical wooden slats held in spaced relationship by wires, the side hingeably connected to the base being of plywood, Figs. 7-9 (not shown). As shown in Fig. 6, the cords 26, 28 may be replaced by straps 64, 66 made of a non-elastic material such as " Velcro " (Trade Mark), which stick together when superimposed. The provision of a vertical extension 52<SP>1</SP> secured by " Velcro " straps is also shown. In all embodiments the device may be folded after use, the base, e.g. 12, being first folded against the wrapper portion, e.g. 16<SP>1</SP>, secured to its edge, the other portions then being wrapped therearound, Figs. 2, 3, 9 (not shown).

Abstract: 650,299. Shearing. MOSELEY BROS. (TOOLS), Ltd., and MOSELEY, W. R. Dec. 6, 1948, No. 31457. [Class 83 (iv)] A self-contained power driven shearing-machine for cutting up scrap &c. into short lengths as it leaves a press or the like is mounted on the floor adjacent the press and is adjustable in height to suit the height of the press. The shearing machine is slidably guided on an inclined bed 11 by ribs on the under face of its frame 13 which engage T- section slots 12 on the bed 11 and may be locked in any position thereon by bolts through its base engaging the slots. A screw adjustment may be provided comprising a screwed spindle in a block at the lower end of the bed 11 adapted to engage the lower end of the frame 13. An electric motor 14 slung to the frame 13 drives a reciprocating shear blade 25 through a belt pulley 16, pinions 18, 19 and an eccentric 20 carrying a block 21 sliding in a slot 22 in the blade support 23. The scrap is guided to the blades over a saddleshaped guide 36 adjustable both vertically and angularly so that the work passes through an aperture 28 in the machine casing to a fixed tapered funnel 27 immediately in front of the moving and fixed blades 25, 26. After cutting, the waste drops into a receptacle in the base 10 of the machine. The machine is totally enclosed in a casing 29, an aperture 37 being provided for access to an oil well 38 from which oil is fed to the various parts.

A switching device comprises a switch 12, a rotary cam mechanism for operating the switch and having a face cam 4 and a cam follower 8 which is angularly adjustable relative to the cam, the cam mechanism being movable away from the switch so as to disengage the mechanism from the switch. The follower 8 comprises a pin secured to a normally-stationary shaft 3 upon which the cam 4 is rotated by a clock (not shown). The cam is biased towards the pin 8 by a spring 7 and lever 6, the latter having a turned-over end 10 co-operating with the operating plunger 11 of switch 12. The shaft 3 is normally held in the axial position shown by the edge of an aperture in a slide 13 which is biased upwards by a spring 14. Manual depression of the end 15 of the slide allows the spring 7 to move the shaft, cam and pin to the left so that the lever end 10 is moved clear of plunger 11. The parts may be pulled back to the right to release slide 13 by a knob 16, which is also used to adjust the pin 8. The shaft carries a setting indicator 21.

Title: Improvements in or relating to firearms
IPC: F41A11/00
Filed: 1923-12-18
Abstract: 215,682. Browning, J. M. Dec. 18, 1923. Breech actions, sliding breech-block; protecting from dust and rain. - The cover-plate for the ejection opening of an automatic firearm is operated by a lever co-operating with an externally projecting member on the reciprocating actionslide in such manner that retraction of the slide causes the uncovering of the ejection opening and, when the ejection opening is closed with the action-slide in the rear or cocked position, the action-slide is locked. The invention is shown applied to a gas-operated rifle of the kind described in Specification 133,379. The cover 10 for the ejection opening is pivoted at the front of a lever 9 which is pivoted to the side of the breech-body 1. To maintain the cover parallel to the opening, a rib along the top edge of the cover projects into the opening and engages either the top or the bottom edge. The lever 9 is provided with a thumb-piece 9f at the rear, to enable it to be manually operated, and on its lower edge, forward of the pivot 9<a>, with a forwardly projecting arm 9<d>, the forward end 9<e> of which projects upwardly. If the cover is closed, when the actionslide is retracted the handle 8<a> of the slide engages the projection 9<e> and operates the lever to uncover the ejection opening. When the actionslide is cocked and the cover closed, the projection 9<e> engages in front of the handle and locks the action-slide which is cammed back slightly to ensure free action of the sear. The action-slide 8 extends backwards beyond the handle and always closes the slot 1<a> in which the handle works. The handle may be hollowed out for lightness.

A vehicle tow bar comprises a pair of clamps 2 for attachment to the steering arms 4 of the front wheels 20 of the vehicle to be towed, means 27 for attachment to a tractive vehicle (not shown), and a pair of longitudinally extensible and contractible connecting members 16 each yieldingly connecting a clamp 2 to the means 27, whereby, when the bar is attached to both vehicles, turning of the tractive vehicle will result in the length of the members 16 being automatically adjusted to deflect the steering arms, and hence the front wheels, to cause the towed vehicle to follow the turn of the tractive vehicle. As shewn in Fig. 1 the means 27 is connected to links 24, the links 24 having knuckle joint connections 25 with the members 16. The links 24 are interconnected by a telescopic member 30 to accommodate differing tracks of the towed vehicle. The members 16 each comprise a rod 17 carrying a piston within a cylinder 11, the piston having an adjustably tensioned double spring connection with the cylinder 11. Each clamp 2 includes a resilient bush surrounding the steering arm 4. In a modification the links 24 are replaced by a single bar, the rods 17 being bent through a right angle and having a telescopic connection with the bar. In another embodiment, Fig. 4 (not shown), the member 30 is replaced by a clamping arrangement adjacent the means 27. In a modification the double spring connection in each member 16 is replaced by a fluid arrangement, the rod 17 carrying within the cylinder 11 a collar having a bleed passage between the two sides thereof. The members 11, 17 may be of arcuate form.

Title: Improvements in or relating to method of preparing silica aquasols
IPC: C01B33/141
Filed: 1949-12-15
Abstract: Silica aquagels are converted to silica aquasols without the formation of mud or scaling of the apparatus by heating a mixture of substantially neutral silica aquagel, which is substantially free of electrolytes, and a heat stable, alkaline reacting silica aquasol in an autoclave or other pressure-resistant closed container at a temperature above 125 DEG C. while substantially preventing boiling of the mixture.  The alkaline-reacting aquasol should contain sufficient of a free basic compound, e.g. alkali-metal silicates, hydroxides or carbonates, quaternary ammonium hydroxides, or ammonia, to convert the aquagel to aquasol.  Boiling may be prevented by employing a tight container filled with the mixture or when a partially filled container is employed, by introducing live steam into the free space above the mixture.  The aquasols may be concentrated by evaporation or vacuum distillation, may be acidified to form acid reacting sols and may be converted to organo-aquasols by the addition of organic solvents.  They may be employed for coating paper and for the treatment of textiles.  The aquagels and alkaline reacting aquasols are prepared by the usual methods, several of which are described and in this respect reference is made to Specification 649,897.
