Title: An improved elevator for pipes
IPC: E21B19/06
Filed: 1947-09-29
Abstract: 637,405. Well-pipe grapplers. STANDARD OIL DEVELOPMENT CO. Sept. 29, 1947, No. 26316. Convention date, Feb. 10. [Class 85] [Also in Group XXX] In a well pipe elevator an expansible screw - threaded mandril A is caused by a tapered rod 34 to engage with the internal threads of a pipe or joint box. The mandril is loosely carried by and below a tubular body 11 whilst the rod 34 has a sliding fit in the base of the body 11, and the lower portion of this body 11 is closed off by a concentric tubular body J to form a chamber in which moves a piston C attached to the rod 34, the piston being urged downwards by a spring D. As the elevator is lowered on to the pipe, a ring 42 engages the pipe and moves upwards relative to the rod 34 against springs 41 to force up a ring 43 against spring 44, so allowing the locking balls 45 to be urged clear of the groove 32 as the rod is driven downwards by the spring D to expand the mandril A. The upper portion of the body 11 has telescopically mounted upon it a sleeve H so that an annular chamber 65 is formed between them. When the mandril has first been expanded, further lowering of the elevator hoist allows the sleeve H to slide downwards until it engages the collar 10 so that the volume of the chamber 65 increases and oil flows from the reservoir 63 formed in the body J, through a non-return valve 68 into the chamber 66 to act on the top of the piston to supplement the expanding force exerted on the mandrel by the spring D. Excessive pressure in chamber 66 is relieved by a valve 62, the oil passing back into the reservoir. To release the mandrel, compressed air is supplied to the under side of the piston from a hose K, the oil in chamber 66 being forced into the reservoir and the rod 34 being raised until, as the elevator clears the end of the pipe, the balls 45 enter the groove 32 as the ring 43 is forced downwards by the spring 44.

Abstract: 1300686 Automatic voltage control GENERAL MOTORS CORP 19 April 1971 [16 April 1970] 26579/71 Heading G3R A voltage regulator control device comprises a plurality of series connected resistors 46, 48 located in a housing 16 which provides the control setting for the voltage divider 42, 44 and output transistor Q2 of the voltage regulator 14, and a cap 18 containing a conductor 72 which when plugged into a selected position on the housing 16 determines the control setting. In Fig. 1, a battery 10 is charged by an alternator 12 the output of which is rectified by the full wave diode bridge rectifier 32 and which is also applied to the slipring connection 36 of the rotor field windings. The other end of the field winding is connected via slipring 38 with the collector of transistor Q2 which is rendered non-conductive when the alternator output, sensed at reference point 54 of the voltage divider, is sufficient to break down the Zener diode 55 and bias transistor Q1 into conduction. By increasing the resistance between the voltage divider point 54 and terminal 50, e.g. by inserting cap 18 into position 79d on the housing 16, the alternator 12 must produce a higher output to achieve the break down potential at point 54. The housing 16, Fig.5, has a lip 134 which engages an abutment 97 on the end wall 96 of the alternator housing, a ramp 122 of the housing also engaging the side wall 98. The terminals 50, 52 of the regulator 14 protrude through the aperture 92 in the alternator housing 90 after the regulator has been mounted on a heat dissipating pad (94) on the end wall 96, by screws 17.

Title: Improvements in oxygen breathing apparatus
IPC: A62B7/02
Filed: 1925-10-24
Abstract: 251,178. Siebe, Gorman & Co., Ltd., and Davis, R. W. G. Oct. 24, 1925. Respirators.-In respiratory apparatus having means for delivering a constant supply of oxygen and an additional supply dependent on the needs of the user, all the gas is supplied through a single connection. Oxygen is delivered from a cylinder through a reducing valve to a fitting d<2>, Fig. 5, from which, normally, it passes at a constant rate through an orifice e to the breathing bag. The orifice e is formed in a removable plug f<1> in the head of a valve f which, under the action of a spring j. normally closes passages g for the additional gas-supply. The stem h of the valve f is capable of sliding in the passages g and is formed with flats i and transverse passages i<1>. The breathing bag b, Fig. 3, which is connected to the reducing valve by a single connection d<1>, contains a curved blade-spring k anchored at one end to a support l secured to the fitting d<2> and bearing at its other end against an annular sliding member m which abuts against the stem h. The arrangement is such that if the user's requirements exceed the constant gas-supply, the bag b collapses and flattens the spring k, so causing the valve f to move and uncover the passages g. Additional oxygen then enters the bag through the passages g, i<1> until the bag is sufficiently inflated to allow the valve f to close. The bag b may be provided with stiffening plates b<1> and the spring k may bear directly against the stem h. Also, as shown in Fig. 7, the orifice e may be formed independently of the valve f. Fig. 1 shows the complete apparatus, the gas admitted through the reducing valve d into the expansion chamber c and bag b in the manner described above being inhaled through a cooling chamber q and exhaled into the bag through a purifying chamber u. A bye-pass p controlled by a valve o is provided to permit direct admission of gas into the fitting d<2>.
