Abstract: 995,753. Centrifugal blowers. F. REITERER, AND L. WINDISCH. April 4, 1962 [April 13, 1961], No. 12984/62. Heading F1C. [Also in Divisions F4 and H2] A travelling blower, of the kind in which a blower is mounted on a carriage moving along a track disposed above a set of machines for removing dust from these machines in succession, has two separate motors on the carriage one vertically beneath the other, one motor being adapted to effect translational motion of the carriage and the other the operation of the blower. A shaft 7 of an electric motor 6 is flexibly coupled at 8 to a shaft 9 on which is mounted the blower hub 10 carrying blades 11. Within the hub 10 is an electric motor 12 having a hollow shaft 13, the motor 12 being cooled by air passing through apertures 23 in the hub 10, which air is evacuated from the hub by auxiliary vanes 24. The shaft 13 carries a worm 14 which meshes with a gear 15 and drives a horizontal shaft 16 carrying rollers 4 and 5. The shaft 16 drives a second shaft 20, provided with rollers 4<SP>1</SP> and 5<SP>1</SP>, through a chain 19 and sprockets 17, 18. The rollers 4, 4<SP>1</SP> and 5, 5<SP>1</SP> run on rails 2, 2<SP>1</SP> on a fixed frame 1 constituting the track for the moving carriage. The latter is caused to reciprocate along its track by periodically reversing the current fed to the motor 12 by means of adjustable stops disposed at each end of the track, which stops operate a change-over switch. The electric motors 6, 12 are three-phase machines and are energized through brushes T, S, R which contact longitudinal conducting strips 3, 3<SP>1</SP>, 3<SP>11</SP> carried by the fixed frame 1 on insulating supports. The windings of the respective motors can be connected alternatively in delta or star to give two different speeds of rotation which are approximately in the ratio of 1:2, the speeds being selected, in accordance with a predetermined programme, either manually by changing over electrical plugs or automatically by arranging stops along the path of the carriage to operate change-over switches.

Title: Apparatus for the mechanical purification of water
IPC: B01D33/00
Filed: 1922-05-09
Abstract: 192,333. Geiger, E., and Buderus'sche Eisenwerke, Abteilung Geiger'sche Fabrik. May 9, 1922. Travelling-band strainers.-An endless band is formed of strainer frames 1 suspended from bolts 5, which connect and form pivots for the links of chains 3 on either side of the band which transmit motion to the band. The frames form a closed straining surface on the forward side of the band, a stop-bar on the free end of each frame bearing on the curved pivoted end of the adjacent frame. The frames on the return side of the band turn on the pivots in a rearward and downward direction, so that the purified liquid can flow freely between them. The band is placed across a water-channel in an inclined position, rollers 4 on the ends of the bolts 5 engaging guide rails 6 on the sides of the channel. The upper portion of the forward side of the band is guided in an approximately vertical direction and overhangs slightly at the front, so that each frame swings forward as its free end is raised over the edge of a trough 10 into which impurities collected by the frame are washed by jets of water from pipes 11, 12. On the other side of the band the frames pivot backwards against buffers 14, and any matter still adhering to the frames is caused to fall into a gutter 15. In order to increase the effective straining area, the lower end of the band is guided in an approximately horizontal direction as shown in Fig. 2. Closure between the band and the bottom of the watercourse may be effected by means of a hinged sill 18, vertically adjustable in guides 19 and provided with an elastic strip 20 which rests against the band and can rise slightly to allow passage of projecting cross-bars 13 fixed to some or all of the bolts 5. The bars 13 lift any bulky impurities separated from the water. These matters are pushed from each bar 13 into the trough 10 by the bar 9 on the frame immediately above, as the latter swings outwardly over the trough. As shown in Fig. 7, the bars 13 make closure between the band and the bottom of the channel as they slide over a metal covering 23 on a break or step on the bottom of the channel, which is curved similarly to the corresponding portion of the guides 6. Closure at the sides of the band may be made by yielding strips which are secured to the guide rails 6 and bear on the sides of the frames 2, or by metal strips 24, Fig. 8, fixed to the sides to the frames, and sliding along the flanges of strips 25 fixed to the guides 6. The band is driven by an electromotor 26 the motion of which is transmitted to chain-wheels 7 by spur, worm and chain gearing.

Filed: 1926-05-25
Abstract: 268,575. Goodall & Hatton, Ltd., and Lockwood, P. W. May 25, 1926. Hand trucks of the kind having a frame which is elevated 'by means of a slotted link pivoted to the transporting handle are provided with retarding mechanism brought into operation by the operator when the frame is being lowered, such mechanism comprising quadrants on which rollers, confined to move in a circular path, roll and means, including a control rendering the quadrants eccentric to circular path to introduce a retarding ef elevating platform 4 is raised by mean slotted link 10 pivoted at 11 to the h rollers 15 constrained to move in a circu about the centre 6 riding on pivoted quad: and the platform is locked in its elevated position by means of a pivoted latch 24 engaging a spindle 8 and also, when the handle is raised to vertical position, a pin 29 on the control rod 18. To lower the frame, the control rod 18 is moved, causing the pivoted latch to release the frame which thereupon tends to fall under gravity. The control rod has, however, by means of a lever 16, 16', moved the quadrants 12 eccentrically, thus tending to jamb the frame through the rollers 15. Manipulation of the control rod 18 varies the eccentricity of the quadrants and allows the frame to fall gradually.

IPC: A43D95/26
Abstract: 132,327. British United Shoe Machinery Co., (United Shoe Machinery Corporation). Sept. 7, 1918. Coating-machines. - In a machine for applying blacking to the edges of soles or heels of boots and shoes, of the type having a randcrease guide or disk and a rotary brush acting along the edge of the shoe bottom, adjusting-means are provided for varying the angular relation of the brush and guide to adapt a single brush to conform to different shapes of heels, and a member. moving relatively with the disk or guide coacts therewith to assist in opening the crease and iurce blacking into it. As shown in Fig. 1, the shaft 52 of the rotary brush 50 is mounted on a framework supported on a flat plate 54 having a curved groove on its underface engaging a curved rib 60 on a lower plate, the latter being similarly fitted by means of a straight groove and rib 62 to the frame of the machine, whereby angular and radial adjustments of the brush about the acting point a of the rand-crease guide-disk 20 are obtained. A nut 58 clamps the plates in adjusted position. The framework carrying the brush also carries a driven disk 80 supplying blacking to the brush from a trough, and a driven bristle-straightening comb 84. The rand-crease disk 20 receives blacking from a disk 24 dipping in the same receptacle, and has mounted adjacent to it a bar 30 which is reciprocated by means of rollers 32 and a cam-plate 34 and has a wedge-shaped end to assist the disk 20 in opening the crease. The relative movement between the bar 30 and disk 20 also causes an accumulation of blacking at the point of engagement with the work, and the blacking is pushed from the edge of the disk into the crease. In a modification, Fig. 5, wherein the reciprocating bar is dispensed with, a second disk 92 having a number of peripheral wedge-shaped projections is mounted within the disk 20. The disk 92 is driven at a higher speed than the disk 20, and the wedge projections act in a similar manner to the reciprocating tool to open the crease of the boot.

Abstract: 582,783. Pumps. KAMMER, G. S. July 12, 1944, No. 13357. [Class 102 (i)] [Also in Group XXVII]- In a combined fuel injector and pump the pressure space 12 communicates in the rest position, as shown with the fuel 1 supply through radial orifices 16, a circumferential groove 14 and inlet ducts 18. The orifices 16 are covered as the plunger 2 descends and the pressure immediately, rises, causing injection of pilot fuel through a hole 32, an extended groove 26, and a hole 39 which is drilled at approximately the same obliquity as the faces 37 and 24 of the valve and'valve seat. At the same time some of the fuel leaks back to the supply through a control orifice 19 and duct 20. When the plunger covers the control port another port 10 is simultaneously uncovered by the lower edge of groove 8 so that leakage through the control port ceases and most of the fuel is delivered to the cylinder through a port 10, a duct 21, 'a groove 36, a duct 35, a groove 34, holes 33, grooves 27 and the remaining holes 39 but some still passes through the. hole 32. Before the plunger reaches the bottom of its stroke one of the ports 16 is uncovered by the helical edge 9 and injection ceases abruptly as there is no pressure available to keep the valve open. The duration of main injection is controlled by the position of the helical edge 9 which can be varied by rotating the plunger by means of rack 6. Specification 556,742 is referred to.

May 11, 1933, No. 13756. Convention date, June 22, 1932. [Class 40 (v).] The output from a radio-frequency transmitter 1, Fig. 1, is supplied to an aerial-feeding transmission line 8 by an inductive coupling 2, 3,the degree of coupling being adjustable by including variable series impedance coils 9, 10 in each side of the line 8, or a variable condenser across the line, or both. Preferably a second transmission line 7 is provided as an alternative to the line 8, a switch 4 being provided for changing over to a different wave-length. In this case, the coupling may be designed to suit one of the lines, and the variable impedances 9 provided in the other line. Series blocking condensers 6 are included in each line. The plate supply lead, which is connected to the mid-point of the transmitter coil 2, is also connected through a high resistance 5 to the coil 3 to prevent arcing between the coils. In Fig. 4, series coils 9, 10 and shunt capacity 21 are both employed, the capacity 21 being divided and its centre plate earthed through an adjustable coil 13. By tuning the coil 13 and condenser 21 to the second harmonic, energy of this frequency is byepassed to earth. A condenser 14 connecting the mid-point of coil 3 to earth also reduces the second harmonic, whilst in Fig. 6 the same purpose is effected by connecting each side of the transmission line 7 to earth through a line or coil 30 whose effective electrical length is one-quarter of the wave-length. Switches 15, Fig. 4, serve to connect the idle aerial and line to earth.
