Title: Hydraulically operated back gauge or work-feeding bar for cutting machines
Inventor: FRANKEL SYDNEY
IPC: B26D7/01
Filed: 1951-08-29
Abstract: 707,088. Cutting machines. LAWSON CO., Inc., E. P. Aug. 29, 1951, No. 20432/51. Class 31 (1) The work-feeding bar 201, Fig. 1, of a machine for making a series of cuts on a paper stack is movable along the cutting-table 100 by a longitudinal screw 204 operable by a hydraulic motor 104 which is included in a hydraulic system comprising a fluid reservoir 81, a container 82, Fig. 4, for fluid under pressure, a pump 83 for delivering fluid through a connection 91 and a multiple-control valve 97 to the motor 104, and a second connection 99b for delivering fluid at lower pressure from the opposite side of the motor through the valve 97 to the container 82. The drive from the hydraulic motor 104 to the screw 204 is through belt and pulley mechanism 60 ... 65. The pressure fluid container 82 is a cylinder disposed in the reservoir 81, pressure being maintained in the chamber 73 thereof by a spring-urged piston 76. Fluid from the reservoir passes through filters 89, 90 to the pump 83 and thence through a main relief valve 92 and filter 96 to the valve 97. For rapid forward movement of the bar 201 between successive cuts, the valve 97 is set as shown in Fig. 4 so that fluid then passes through the pipe 99b to the motor 104; exhaust from the motor 104 is through pipes 99a, 199a, a second valve 98 and the valve 97 to the pressure chamber 73. To slow down the bar 201 as it nears the end of its movement, the valve 98 is set so that exhaust from the motor 104 passes through the restricted orifice 120, with relief through the valve 122 ; any excess in the pump delivery is then diverted by the main relief valve 92 to the reservoir 81. At the stop position of the bar, the valve 97 is set so as to cut off the pump supply to the motor and transfer it to the pressure chamber 73. Return of the bar after it has completed its full range of forward movement is effected by setting the valves 97, 98 so that fluid passes through both valves to the motor 104 and then back to the valve 97 and pressure chamber 73. A relief valve 111 provided between the pipe 99b and reservoir 81 opens at pressures substantially above that of the pump so as to provide relief should, the discharge 'from the motor 104 be suddenly blocked when the latter is running in reverse. The valves 97, 98 are operated by solenoids and may be controlled automatically. Specifications 707,087, 707,089 and 707,090 are referred to.

Abstract: 1343057 Boring earth and rock SALZGITTER MASCHINEN AG 19 April 1971 [6 Feb 1970] 20457/71 Heading E1F A percussively driven core barrel 40 takes a geological core sample 45 while a casing 10 having a bit 13 is rotated and drilling fluid is passed, the core barrel being maintained projecting axially beyond the bit so that the drilling fluid (circulated in the direction of arrows 49, 50) does not mix with the sample 45. The core barrel is threaded to a member 25 which receives impacts from a driving element 21. The element 21 is raised and dropped by a cable 20 and is guided by rods 27, 28, 29 connecting the member 25 to a plate 32 having an aperture 31 for limiting the upward travel of the element 21. Alternatively a pneumatic, hydraulic or electrical percussion drive may be provided. Initially, the core barrel is rammed into the ground projecting axially from the bit and casing, and then the casing is caused to drill into the ground around and following the casing. For this, the casing is closed at its upper end and connected to a supply of drilling fluid for circulation through the apparatus. When the core barrel is full the assembly is withdrawn by the cable 20. The core barrel is unscrewed from the memebr 25 and the sample removed or sealed with paraffin wax for storage. Then either a new core barrel assembly or the emptied original is lowered through the casing in the previously drilled hole and the method is repeated.

Title: Safety fuse with time and impact action
IPC: F42C9/06
Filed: 1970-04-30
Abstract: 1299407 Projectile fuzes FORENADE FABRIKSVERK 30 April 1970 [19 May 1969] 20779/70 Heading F3A A fuze for setting hand grenades and mortar bombs for impact and/or delay action comprises a spring-loaded piston 7, Fig. 1, carrying a percussion cap 14a, and a spring-loaded hollow piston 13, Fig. 2, containing a delay charge 35, the piston 13 being movable only when the piston 7 is in an armed position, i.e., with the percussion cap 14a aligned with a striker 6. When the fuze is to be used, safety pins 7a and 15 are first removed, and the piston 7 is pushed inwards, either manually in the case of hand grenades, or by the pressure of the propellant gases in the case of mortar bombs. As the grenade or bomb is projected, a ball 9a sets back from a magnet 9 and drops into a recess 8b, whereupon a spring 19 pushes the piston 7 into its armed position against the delaying action of a vacuum behind the piston. A flange 13a, Fig. 2, of the piston 13 is thereby disengaged by the piston 7, and a spring 26 drives the piston 13 against a striker 12 to ignite the delay charge 35. The flash from a primer 36 subsequently ignites the percussion cap 14a. If impact of the grenade or bomb occurs before flash-over, a ball 5 attracted to a magnet 3 drives the striker 6 into the percussion cap. To set the fuze for delay only, the safety pin 15 is not removed and to set the fuze for impact only the piston 13 is locked in position.

Title: Improvements in or relating to synthetic resin compositions
IPC: C08K3/34
Filed: 1963-05-24
Abstract: A dry composition comprises (a) a water-soluble condensate of an aldehyde containing not more than 7 carbon atoms with a phenol, urea or melamine, (b) 20 to 80% by weight of (a) of a water-soluble alkali metal silicate and (c) up to 500% by weight of (a) + (b) of a solid, inorganic, water-insoluble filler.  The dry composition may be mixed with water to give a viscous coating or adhesive composition. The composition may also contain an ammonium salt, acid or alkali as catalyst for the resin. Specified fillers are mica, asbestos, quartz, clays, silica, various cements, zinc oxide, gypsum and calcium carbonate which latter acts as a foaming agent in compositions of low pH.  When the composition is mixed with water the pH is preferably 6 to 8.5 and a buffer such as sodium phosphate may be included; immediately prior to use an alkali may be added to raise the pH above 9 to accelerate setting.  Coating compositions.-The aqueous compositions may be used to coat building boards of absorbent material such as asbestos, asbestos-cement or plaster boards.  If less water is used than is necessary to dissolve all the soluble ingredients the coating will have an affinity for waer-based paints. These may also be used as plastering compositions.ALSO:Coating compositions comprises (a) a water-soluble condensate of an aldehyde containing not more than 7 carbon atoms with a phenol, urea or melamine, (b) 20 to 80% by weight of (a) of a water-soluble alkali metal silicate and (c) up to 500% by weight of (a) + (b) of a solid, inorganic, water-insoluble filler.
