Abstract: 463,937. Tipping pen-nibs. AMERICAN PLATINUM WORKS. Dec. 16, 1936, No. 34505. Convention date, Dec. 21, 1935. [Classes 83 (ii) and 83 (iv)] In a method of tipping pen-nibs with, for example, an iridium tip, the tip is caused to enter a recess in the nib, which extends transversely of the longitudinal axis of the pen point, and a low-voltage electric current, for example from 2 to 30 volts, is passed for a predetermined time through the nib and tip to effect a substantial welding of the tip to the nib. The nib is clamped in a holder 4 at the end of a long pivoted arm 6, an adjustable stop 8 being provided for limiting the amount of movement as the nib and tip are welded together. After the nib and tip are brought into contact a timing device comprising an electric motor 13 driving through reduction gearing an arm 10 which contacts for a short time the member 15, thereby closes a circuit through the nib and tip through which a low voltage current, for example, between 2 and 30 volts, flows to weld the nib and tip. A reducing atmosphere may be used in known manner during the welding operation.

Patent GB-1479940-A (GB)
Title: Pneumatic to hydraulic converter for hydraulically actuated friction brakes
IPC: B60T13/44
Filed: 1974-08-07
Abstract: 1479940 Pneumatic to hydraulic actuating cylinders GENERAL SIGNAL CORP 7 Aug 1974 [31 Aug 1973] 34715/74 Heading F2F [Also in Division F1] In a pneumatic to hydraulic converter a first hydraulic piston and cylinder motor 35 is actuable by a first pneumatic motor 34 and by a spring motor restrained by a second pneumatic motor 18; a second hydraulic piston and cylinder motor 12 has one chamber 96 connected to the first hydraulic motor, the other chamber 97 being connected to an outlet, and a valve assembly 115 which permits fluid flow from the one chamber to the other when the piston 110 almost reaches its travel limit into the other chamber and which permits fluid flow from the other chamber to the one chamber upon a predetermined pressure differential between the two chambers. Pneumatic pressure is fed via a pneumatically or electrically controlled valve to a chamber 39 to operate a diaphragm 41 and piston 42 of the first motor 34, which, by means of a member 43, moves the hydraulic piston 44 of the motor 35. For emergency braking or parking, full reservoir pressure is decreased in a chamber 51 for the motor 18 by an electromagnetically operated valve or a manually operated valve which opens the chamber to exhaust. This causes a spring 46 to move a piston 47 with a sleeve 48, a threaded insert 99, and a threadedly adjustable rod 49 (for manual brake release), to act on a rod 50 which abuts the piston 42. However, if a pressure exists at the time in the pneumatic line to the chamber 39, a two way check valve allows this pressure (when it is higher than the "emergency" line pressure) to be transmitted to the chamber 51 so that the force on the member 43 is provided by the spring 46 only. The second hydraulic motor 12 acts as a slack adjuster; upon actuation, e.g. for braking, chamber 96 and a chamber 95 of the first hydraulic motor are isolated from a reservoir 98, the piston 110 is moved leftwardly. If this piston does not reach its limit, defined by an end cap 130, pressure in the chamber 97 exceeds the predetermined difference with the chamber 96 for the valve assembly 115 to open (by means of spring biased ball 119) to allow eventually, by repeated openings, the piston to abut the end cap 130. Just before this abutment, a push rod 120 opens the valve ball 119 for direct communication between the chamber 96 and the recipient hydraulic devices) associated with the converter, this chamber pressure being proportional to the pneumatic command pressure. Upon release, rightward piston movement causes the piston to return to a particular position independent of the original pre-actuation position and the initial actuation stroke before valve assembly operation. To prevent inadvertent transfer of fluid from the recipient hydraulic device(s) to chamber 96 a check valve member 131a engages a seat 133 on the piston 115 just before the ball 119 is operated by the rod 121. A spring 132 offers minimal resistance to flow from chamber 96 to chamber 97 during this engagement.

Classes 7(3) and 7(5) A stop lever 21, co-operating with an abutment 28, carried by the injecting pump control rod 11, to limit the normal maximum supply position of the rod is moved sideways along its pivot axis 24 to a starting position 21a, Fig. 2, in which it clears the abutment 28 to permit the rod 11 to move further to the left to an excess supply position; in moving sideways, the lever 21 carries with it a spring-loaded pawl 39, pivoted on the abutment 28, which springs back, when the rod 11 moves to the right after starting, into a position opposite the starting position of lever 21 to prevent rod 11 moving to its excess supply position after starting if the lever 21 is held in the starting position. The abutment 28 is part of the connection 12 between the rod 11 and the diaphragm 15 of a suction type governor. The lever 21 is carried by a spring- loaded shaft 24, Fig. 2, which is extended to form a push button 37 by which the shaft is moved axially for starting. The initial position of lever 21 is adjusted by a screw 26. A sleeve 31 surrounding the member 37 carries a stop lever 32 by which the rod 11 is moved to cut off position. Specification 827,678 is referred to.

Abstract: 386,778. Table games ; toys. BRADSHAW, R. H., Caithness, Estcote Road, Ruislip, Middlesex. Dec. 17, 1931, No. 35014. [Classes 132 (ii) and 132 (iii).] In games apparatus comprising a device for projecting a ball or other missile, the missile is yieldably retained upon a holder, by magnetic means in such a way that it is released and projected when the forward movement of the holder is suddenly arrested. A rectangular baize-covered board 1 with a semicircular recess 2 at one end has secured to it a frame 3 in which is pivoted a rod 5, the rod being adjustable vertically in the frame. The rod carries a horizontal pivot 8 for members 10 connected to a platform 11 to which is adjustably secured a magnet 12. The platform is formed with a step 15 against which the magnet 12 normally holds a steel ball 16. In use, the platform is swung back about the horizontal axis 8 by a cord 22 and is then released. When the edge of the platform strikes the board 1, the ball 16 is ejected and rolls along the board. The ball may be biased. A quoit ring may be used instead of a ball, the front edge of the platform 11 then being curved to project the ring upwards into the air. In a further modification, the missile comprises a steel plate having a point in one of its sides, the point being projected by the apparatus into a vertical target after the manner of a dart.

Abstract: 1,158,075. Nut runners. INGERSOLL-RAND CO. 31 July, 1967, No. 35115/67. Heading B3N. [Also in Division F2] A fluid-pressure actuated power wrench comprises a fluid - pressure motor 7, which drives a spindle 10 connected to an output shaft 5 by gears. Motor shaft 8 is connected to shaft 10 by a torque responsive clutch 14 which comprises a helical spring 19 which is expanded out of engagement with a driven member 16 when the torque exceeds a predetermined value, to cause yield of a torque-sensitive coupling between clutch part 15 and shaft 8, the clutch remaining disengaged until the motor is switched off. The sleeve 24 has helical slots 29 housing rollers 30 pivoted on pins mounted in a collar 32 and having a pin 31<SP>1</SP> extending through an axial slot 33 in a stub shaft 27 which is splined to the clutch part 15. The rollers 30 are biased to the rear of the slot by a spring 36 acting through a cup 34. A spring seat 37 for the other end of the spring is held in place by a nut 38 threaded on the sleeve 24 and which can be adjusted by a gear key 42 to vary the torque at which the coupling yields. On yielding, rotary movement of the part 15 relative to the sleeve 24 expands the clutch spring 19 to reduce the clutching engagement, and at the same time a piston rod 59, which is biased into abutting engagement with the pin 31<SP>1</SP>, shifts forwardly to permit a valve element 52 to seat on seat 48, cutting off the air supply to the motor 7, and cutting off the pressure to the forward (left-hand) face of a piston 58, so that the pressure falls, and the pressure on the right-hand face of the piston shifts it forwardly (to the left), and thus shifts the rollers 30 to the end of their slots to complete clutch disengagement and ensure that the clutch remains disengaged until manual actuation of a throttle button 12 cuts off the supply of compressed air to the right-hand face of the piston.
