Title: Improvements in the manufacture of chains
IPC: B21L9/00
Filed: 1921-10-26
Abstract: 192,151. Hewitt, J. H., and Wilkins & Wright, Ltd. Oct. 26, 1921. Chains. - A machine for making sprocket and like chains comprises a bobbin 5, Fig. 1, from which stripmetal is fed to a blank-punching apparatus 1 which delivers the link blanks through a gravity chute 6 to a mechanism 2 where the lÝnks are assembled and the rivets inserted, the chain being subsequently fed to a riveting-apparatus in which the rivet heards are formed by rotary rubbers. The blanks 3, Fig. 4, having been made by the punching- apparatus 1, pass by gravity to a channel 9 of sufficient width to accommodate the links in the finished chain. A feed plunger 10, cam-driven through an eccentric adjustment 56, and recessed so as to give an advanced feed to certain of the blanks, slides the links of one unit of the chain under spring spacing-fingers 14, 15, Fig. 9, mounted in a stationary member 12, the latter being also fitted with a spring-pressed chain-holding pin 22. The feed is arrested when the link holes are opposite a pair of alining-pins 27, Fig. 7, mounted in a feed slide. 30, which mav be reciprocated with variable stroke by the cam linkage 69, 68. The rivet wires 33 supplied from bobbins pass through a guide 32 composed of grooved discs, and are thence led through holes in a transversely-reciprocated shear-guide 36 mounted on a fixed block 8. A gripping-block 40 is fitted in the shear-slide and the operation of the machine is such that the grip 40 is applied and the grip 32 released while the slide 30 travels to the left to aline the links in the channel 9, after which the grip 40 is also released and the slide 36 reciprocated to shear the rivets 37. The grip 32 is then applied and the slide 30 moved to the right, whereupon the wires 33 feed the rivets into the link holes. By the continued operation of the plunger 10, the assembled links and rivets are fed forward in the channel 9 to a pivoted plate 100, Fig. 4, which is periodically camoscillated in a vertical plane to hold the links during riveting. The riveting-apparatus comprises rubbers 80 rotated by belts in opposite directions and reciprocated towards and from each other by an eccentric and linkage 92. The rubbers are mounted in sleeves carried by a swinging frame 82 oscillated through an angle such that during each oscillation the rubbers may operate on the two rivets of each chain-unit. The various motions are derived from eccentrics. cams and springs and adjustments and limit stops such as 57, Fig. 4, are provided as necessary.

Filed: 1950-11-22
Abstract: 673,056. Rotary pumps. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 22, 1950 [Nov. 26, 1949], No. 28558/50. Class 110(ii) A casing 2, formed of two parts 15, 16,. has a spherical bore and contains two sets of recesses 33, 36 in which limited lateralmovement of blocks 32 is alowed. A spherical rotor 22 is proivded with two inclined grooves 27, 28 in which are placed semi-circular pistons 30, 31 the ends of which are pivoted on pins 32 to the blocks 32<SP>1</SP> so that the pistons do not rotate. Inlet and. outlet ports 39, 41, in the recesses 36, 33 are controlled by the blocks 32<SP>1</SP>. Fig. 14 shows a developed view of the rotor 22 in Fig. 6. An expanding or contracting chamber is formed in a groove 27 or 28 betwen a piston end and the side of the other piston at a cross-over point 29 of the grooves. In Figs. 6, 14 with the rotor rotating in the direction of the arrow, a portion 59 of the groove 27 is expanding between an end 45, of the piston 30, and the side 44 of the piston 31, causing fluid to be sucked in through the recess 36 from the port 39. The other part of the groove 27, portion 60, is contracting between the side 58, of the piston 31, and the end 64 of the piston 30, fluid thus being forced out through an outlet recess 35. The piston ends have bevels 51, 52 and 55, 56 the bevels 56, 51 or 55, 52 passing close to each other at the cross-over position. The rotor may have flat ends 23 or be practically wholly spherical. The number of compression stages per revolution may be varied. The two half casings may be screwed together, Fig. 3 (not shown) or formed as two shells within an outer casing 69, Fig. 21 (not shown) being held in position by a ring in a slot in the outer casing and prevented from rotating by a pin engaging'a recess in one half casing. Fig. 23 shows a modification in which half casings each have a curved recess adjacent the surface of the rotor 22. A segment 83 moves in the recess to allow lateral oscillation of a piston 31<SP>1</SP> during rotation of the rotor. The piston is pivoted at 85 to its segment. Fig. 1 shows a refrigerator unit in which a compressor 2 is positioned, by rings 3, 4, within a hermetically-sealed casing 1, the rotor being driven by a shaft 5.

Title: Magnetohydrodynamic generator for providing a.c. power
IPC: H02K44/18
Filed: 1960-08-18
Abstract: 950,469. Generators operating by electromagnetic interaction with fluids. AVCO CORPORATION. Aug. 18, 1960 [Dec. 1, 1959], No. 28643/60. Heading H2A. In a magnetohydrodynamic generator, A.C. power is generated by cyclically switching the current from one electrode (anode) to another inside the duct. As shown in Fig. 2, each pair of anodes 12a, 12b-16a, 16b, sealed inside a gas duct 10, is connected to the ends of a transformer primary 18, and back to the common electrode 11 (cathode) through centre-taps 18a, so that, as the current is alternately diverted to electrodes 15a, 15b, opposite directions of current flow in each half of the transformer primary 18 induce A.C. current in the transformer secondary 20. In Fig. 3 electrodes 22, 23, supported in insulator bushings 26, 27 (of alumina oxide) and driven by cams 31, 36 by motor 33, alternately project into the inside of duct 28 and initiate current flow. Conduction to a retracted electrode is prevented by grids 37, 38 which are maintained at a constant negative potential and is stopped as the electrode is retracted by scavenging the ionized gas from chambers 29, 30 by a cold gas stream produced either by the movement of the anodes, Fig. 4 (not shown), or from an external source where the anode acts as a slide valve, Fig. 5 (not shown). Other methods used to initiate conduction include a pilot anode, Fig. 6 (not shown); hot gas drawn from the duct into the anode cavity by means of a poppet valve, Fig. 7 (not shown), or making the grids momentarily positive; extinction in all these cases is due to the pocket of gas in the chambers de-ionizing. The system may be used to generate polyphase A.C. by having a plurality of anode electrodes and the common cathode electrode connected to the system star point, Fig. 10 (not shown), high frequency generation is also possible.

Title: Improvements in or relating to driving bands or chains
IPC: F16G5/20
Filed: 1938-10-04
Abstract: 519,851. Driving - chains. P. I. V. CHAIN GEARS, Ltd., and ABBOTT, G. J. Oct. 4, 1938, No. 28772. [Class 24] [Also in Group XXIV] In a chain of the kind described in Specifications 228,838, 242,416, [both in Class 80 (i)], and 335,366, comprising slats for engaging a V-pulley, the slats are mounted in carriers which can rock about the axes of the link-pivots. In the chain shown in Figs. 3 and 6, each link-pivot B supports pivotally a slat-carrier consisting of plates C, C<1> which are formed with slots C<2> for receiving a pack of slats consisting of thin slats D formed with enlarged ends, and thick slats D<2> which occupy enlargements at the ends of the slots and can rock slightly. The slats are retained by a plate E which is formed with slots for engaging the plates C, C<1>, and with lugs E<2> for engaging slots D<3> in the slats D<2>. The slatcarriers are preferably arranged contiguously so that when a pack of slats engages the pulley, the rocking movement of the associated slat-carrier is transmitted to the following slat-carriers. The rocking movement of the slat-carriers and the slats enables the packs of slats on the driving side to operate on a slightly smaller diameter than those on the slack side without dragging across the edges of the depressions in the pulley. If one pack of slats takes an excessive load, the associated slat-carrier rocks and transfers part of the load to the next pack. Since the slats are adjacent to the link-pivots, the tendency of the links to rock and thereby render ineffective adjacent links is reduced. According to the Provisional Specification, the slat-carriers may be mounted in large, hollow, link-pivots.

Title: Regulating means with servo-motor
IPC: G05D13/00
Filed: 1937-10-25
Abstract: 485,907. Fluid - pressure servomotorcontrol systems. KALLE, K. T. Oct. 25, 1937, No. 29064. Convention date, Oct. 29, 1936. [Class 135] A servomotor regulating device has the main power device actuated by pressure from a fluid pump adapted to pump either gas alone or gas and liquid under the control of the regulating impulse. In the Figure the device is shown applied to the actuation of a damper controlling the supply of hot air to a room to maintain its temperature constant. The suction conduit of a gear pump 4 is divided into two branches one for admitting gas being provided with a fixed throttle 3 while the other for admitting oil opens within a chamber 7. The conduit 5 connecting the outlet of the pump with the power cylinder has a branch pipe 6 leading to the chamber 7 through which the gas and part of the oil pumped is returned to the chamber. An outlet conduit 9 from the chamber 7 is controlled by a thermally-actuated valve 20 subject to room temperature. The chamber 7 is open at the bottom and is surrounded by a wall 17a having a waist at the normal liquid level in an enclosing chamber and fitted with an adjustable throttle 18 to permit a slow transfer of liquid. Under normal conditions liquid stands at the same level within and without the wall 17a. In the event of the room temperature rising valve 20 tends to restrict the outflow from the pipe, 9 causing pressure to rise in the chamber 7 pushing the level within the chamber below the end of the suction pipe and causing the level to rise in the space between the chamber 7 and wall 17a. The pump only having air to deal with, the pressure transmitted to the power piston is reduced thus permitting the weighted arm 11 to move the valve 10 controlling the admission of warm air towards the closed position. Liquid seeps from the space 17b into the outer chamber and if by this time the room temperature has not reached normal a further regulating action takes place. In a modification, the invention is applied to the control of a liquid level. In this form the outlet end of the pipe is submerged in the liquid to be controlled and the wall 17a is dispensed with.

Abstract: 266,427. Mathews, L. T. Nov. 19, 1925. Copy - holders. - Copyholders are provided with a line-indicator and a pointer operated by means such as the carriage of a typewriter to indicate the successive lines of the copy and the successive characters in the line. The copy-holder comprises a frame 1, Fig. 1, supported by angular brackets 7, and having a sliding indicator in the form of a band 11 carrying a pointer 12. The device is connected to the typewriter carriage by a chain or cord 13, which is attached to a spring drum 17, Fig. 6, mounted on a shaft 24. A stepped wheel 25 is mounted to turn with and slide upon the shaft 24, and is embraced by a yoke 26, which slides vertically upon the shaft 24 and upon a second shaft 27 having a spiral groove. A releasable spring-pressed rod 36 on the yoke engages the groove in the shaft 27, whereby a line-spacing movement is imparted to the yoke. The lineindicating band 11 is attached at one end to the wheel 25 and at the other to a spool 28; or, preferably, as shown in Fig. 9, the band 11 is endless, and passes around the wheel 25 and guide-pulleys 29, 48, a spacing tensioning-device 49 being provided. The guide pulleys 29 are carried in bracket bearings 30 adjustable for different thicknesses of copy. The steps of the wheel 25 enable the travel of the band and pointer to be varied. The shaft 27 is driven in one direction through a ratchet by a wheel 32 connected by a belt 34 to a pulley 33 loosely mounted on the shaft 24. A spring-pressed pin 41, Fig. 3, on the pulley 33 engages ratchet teeth on the drum 17, so that when the drum 17 is turned by the connection 13 during the return movement of the carriage, the pulley 33 and shaft 27 are rotated so as to give a line-space movement to the band 11, determined by withdrawal of the pin 41. by an adjustable member 43. The further movement of the drum 17 by the connection 13 completes the return of the band 11 and pointer 12 to the initial position. During the letterspacing movement of the typewriter carriage, the drum 17 is turned by its spring 19, and the pulley 33 is carried with it by means of a second ratchetdevice to position the pin 41 for the next linespacing movement.
