Abstract: 875,345. Remotely operated fastenings. TRICO PRODUCTS CORPORATION. April 1, 1960 [April 7, 1959], No. 11610/60. Class 44. The boot lid of a motor vehicle is operable both by a manual unlocking part and a power adaptor which is inserted between the lock and the unlocking part and is connected to a power source in the vehicle. The automatic latching lock comprises a plate 7 secured to the boot wall and pivotally carrying a spring-urged latch member 5, a bell crank lever 14 and a rocker 17 in operative engagement. The rocker 17 has a slot 20 accommodating a shaft 24 which, with an integral sleeve 53 and an arm 29, is rotatably mounted on an arm part 36 of a bracket 35 to the boot wall. The sleeve 53 houses a slotted socket member 25 which is rotatable relative thereto through an angle determined by the arc movable by pins 54 of the socket in slots 55 of the sleeve. The socket member 25 houses the shaft 21 of a barrel lock 22 unlocking movement of the key 23 of which causes the shaft 21, member 25, arm 29, shaft 24 and rocker 17 to pivot clockwise such that the arm 13 of the lever 14 is moved from the spring-urged path of the arm 12 of the latch member 5 to cause the hook 9 of said member to disengage the keeper part 4 on the boot lid. Clockwise unlocking movement of the arm 29 may also be effected by the movement of a member 30 connected to a piston 27 associated with a cylinder 26 pivotally mounted at 34 on the bracket 35. Such movement of the member 30 occurs when the piston is moved inwardly of the cylinder against a spring 28 when the interior of the cylinder is connected through hosing 37, 40, and a valve control unit 39 on the dashboard with a power source 41 such as the intake manifold of the vehicle engine. When the unit 39 is actuated to cut off the cylinder from the source 41 the spring 28 causes the member 30 to move the arm 29 &c. such that the boot lid may be automatically locked on being closed. The remote control may be electrically operated, in such case the piston, cylinder and associated apparatus being replaced by an electric motor.

Title: Separation of cerium from other rare earths
IPC: C01F17/17
Filed: 1965-03-19
Abstract: Cerium values are removed from lanthanide mixtures by contacting a mixture as an aqueous feed solution of pH 1-4 with an organic solution of substantially water immiscible dialkyl phosphoric acid whereby the Ce and other lanthanides are co-extracted; separating an organic phase from the depleted aqueous feed solution; contacting organic phase with an aqueous oxidizing solution 1 to 2 M in mineral acid, 0.01 to 0.02 M in Ag+ and 0.2 M in persulphate anion, whereby Ce is oxidized to Ce (IV) and retained in the organic phase while the other, trivalent, lanthanides are back extracted into the aqueous solution; allowing Ce (IV) in the organic phase to reconvert to Ce (III); contacting the organic phase with a dilute mineral acid (e.g. 2M HNO3) which strips the Ce from the organic phase; and separating the stripped organic phase from the aqueous Ce solution.  The process is preferably carried out at ambient temperature with a kerosene solution 0.4 M in di-(2-ethyl hexyl)-phosphoric acid and 0.2 M in tributyl phosphate; and an aqueous oxidizing solution 1 M in HNO3, 0.01 M in AgNO3 and 0.2 M in K2S2O8.

Title: Improvements in or relating to reversing mechanisms for the valves of gas-meters andother purposes
IPC: G01F3/22
Filed: 1932-04-23
Abstract: 388,597. Snap-action switches. PINTSCH AKT.-GES., J., 71, Andreasstrasse, Berlin. April 23, 1932, No. 11726. Convention date, April 24, 1931. [Class 38 (V).] A mechanism suitable for use in obtaining a rapid reversal of gas meter valves or electric switches at the end of the strokes of a slowly reciprocating member comprises a lever 1 oscillated about its pivot o .by connection, for example by a link 20 to a slowlyreciprocating gas meter diaphragm, a lever 5 operating the gas meter valves and also pivoted on the pivot 0, a lever 8 which is adapted to rock about either of two abutments 10, 11 on the lever 5, and a spring 2 attached to a pin 13 on the lever 1 and connected by a link 3 to a pin 14 at the lower end of the lever 8 so as to maintain one of two forks 23 provided at the upper end of the lever 8 in contact with a pin 12 on the lever 5. In Fig. 1 the lever 1 is about to commence a clockwise movement. Owing to the abutment 10 being slightly to the left of the centre-line 51 of the lever 5 a torque will be exerted on the lever 5 .tending to press the valves on their seats until the pin 13 crosses the line 14-10 when the lever 8 rocks about its end block 17 into contact with the abutment 11 and reversal of the valves and consequently the direction of movement of the gas meter diaphragm is effected. To prevent the lever S from tilting laterally the point of attachment 4 of the spring 2 with the line 3 is arranged in the centre plane of the lever 8 and the distance between the points 4-14 is greater than the length of the lever 8. In a modification the rocking surface of the block 17 is curved and the lever 5 acts on the valves through a spring.

Title: Improvements in or relating to block printing machines
IPC: B41F1/10
Filed: 1934-04-19
Abstract: 423,145. Printing machines. ARMSTRONG CORK CO., Lancaster, Pennsylvania, U.S.A.-(Assignees of Rottmund, F. G.) April 19, 1934, No. 11802. Convention date, May 24, 1933. [Class 100 (ii)] A machine of the flat-block type for printing on linoleum &c. of the kind in which printing- blocks 2 supported by heads 3 are raised out of printing position by cams 8 acting on rollers carried by slides 4, are inked in the raised position by travelling rollers, and are lowered on to the intermittently forwarded linoleum when the cams 8 permit is constructed with latching means adapted to move the printing- heads to a position out of engagement with their reciprocating mechanisms, and to hold the heads in said positions. Each slide 4 is fitted with a chamfered tooth 10 adapted to reciprocate normally out of the path of a latch 11 carried by the strap 13 of an eccentric 12 on a shaft 14. A handle 15 on the shaft 14 is normally in the vertical position, as shown in the left hand of Fig. 1, a spring 18 on the latch being engaged by a screw 17 to press the latch back against the action of a weaker spring 19. On moving the handle 15 clockwise, a spring stud 16 on it is first held in a recess 22, and the latch 11 is then in a position to engage the tooth 10 when the slide 4 is raised to the inking position. On further rotation of the handle 15 the slide is raised to such a position that the block 2 is out of the path of the inking-rollers, and the block can be maintained in this position as long as desired so that any defective material may pass by without being printed upon. A screw 20 limits the rear motion of the latch 11, and a plate 23 serves to guide the latch into position to engage the tooth 10 automatically without fouling of the mechanism.

Filed: 1922-04-27
Abstract: 179,182. Pateras Pescara, Raul, Marquis of. April 27, 1921, [Convention date]. Screw propellers.-A helicopter supported by two oppositely rotating propellers has means for adjusting the incidence of the blades and for locking the propellers in a transverse position to act as planes during forward flight, and means are also provided for warping the blade tips both during rotation and when stationary to preserve the balance of the machine. Fig. 1 shows the upper part of the apparatus with the propeller 10 in cross-section, and Fig. 1<a> shows the lower propeller 11 in longitudinal section. Each propeller comprises a linen-covered frame mounted on a metal boom 12 capable of turning in a sleeve 13 or 14 on the propeller hubs 33, 34. In the position shown, the blade surfaces 10 are continuous from tip to tip so as to act as planes, but the two blades are respectively connected to vertically movable frames 41, 42 so that they can be tilted in opposite directions to form a screw of variable pitch. The frames 41, 42 are secured to shafts 35, 36 sliding in lugs 39, 40 on the sleeve 13, and these shafts are connected to the inner ring of a ball race 30 sliding on the hub 33. The outer ring is connected by a forked lever 25 to a vertical tube 23, connected as shown to a hand lever 15, similar connections extending to the lower propeller. To control the stability of the machine, a lever 93, universally mounted at 94, is connected by ball and socket joints to the inner rings of ball races 95, 96 in the planes of the propellers, and is swung in any direction by means of connections 91, 92 to a control-lever 90. Sleeves 97, 98, Fig. 1<a>, fixed on the outer ring, receive tubes 89 which can turn but not slide in the sleeves. Near the end of each blade the tube 89 carries screws 101, 102 which engage nuts 103, 104 having arms passing through slots in the boom 12 and connected to a subsidiary boom in the blade tip so that axial movement of the tube 89 results in the tip being warped. A key 108 in the main boom prevents rotation of the tube 89 relative to the blade.
