Title: Improvements in and relating to dampening devices for printing machines
IPC: B41N7/04
Filed: 1945-10-10
Abstract: 601,883. Printing-machines. LARSEN, C. E. Oct. 10, 1945, Nos. 26397 and 26398. Convention dates, Sept. 27, 1941, and March 18, 1942. [Class 100(ii)] Damping apparatus for printing-machines is constructed with supply rollers which are divided into sections so that the water - applying rollers have varying actions in different sections of the rollers so as to adapt the damping effect to the nature of the design. The invention may be applied to a machine in which damping and inking rollers are combined in one arrangement so that the water is actually applied by one of the inking-rollers. The supply roller may take the form of a roller formed with a number of annular grooves, or as shown in Fig. 2 may be built up of a number of discs 14 keyed to a shaft 15, or secured thereto by screws. As shown in Fig: 4, a number of interchangeable narrow rolls 20 contact a duct roller 26 and a roller 27 which engages an axially reciprocating supply roller 28. As shown in Fig. 6, a number of independently narrow rolls 20 are detachably secured to an oscillating bar 22 by means of a frame 21 having a pivoted and adjustable connection to a frame 29 consisting of a screw 31 and spring 32. The frames 21 oscillate so as to move the rollers 20 into and out of contact with the roller 27 but the roll 23, with which the roll 20 contacts, is not moved out of contact with the water 24. In further modifications rolls 20 may be spring-mounted in slots in oscillating frames, or may be mounted in an oscillating frame formed of two parts which may be readily disconnected. In a further modification, Fig. 9, rolls 20 oscillate into contact with a roll 27, while maintaining contact with water in the fountain 24, and the frames 21- are oscillated through an adjustable spring connection 32 with the operating shaft 22.

Inventor: WIGHTMAN GEORGE GILLESPIE
IPC: G05D3/12
Filed: 1949-10-14
Abstract: 681,375. Electric selective signalling systems. ENGLISH ELECTRIC CO., Ltd. Oct. 16, 1950 [Oct. 14, 1949], No. 26432/49. Class 40 (i). Relates to means for repeating at a distant trailer unit the position of the wiper arm of a multi-position master switch. As shown the master switch A comprises a three-position rotary switch 1 interconnected by lines 6, 7, 8 with the trailer unit B comprising two similar motor-driven ganged switches 9 and 10, the contact 3, 4, 5 of switch 1 being connected to lines 6, 7, 8 respectively and the corresponding contacts 13, 14, 15 and 16, 17, 18 of switches 9 and 10 being connected to lines 7, 8, 6 and 8, 6, 7 respectively. One side of a power supply 2 is connected to the wiper arm of switch 1 and the other side is connected to the wiper arms of switches 9 and 10 via relays 11 and 12 which when energized individually cause the motor to rotate the wipers of switches 9 and 10 in an anti-clockwise or clockwise direction respectively so that the wiper arms of switches 9 and 10 are rotated to a position corresponding to that of switch 1. The system may be used for remote operation of a multi-position tap-changing switch 19 coupled through reduction gearing 20 to the shaft of switches 9 and 10, an indicator 21 being similarly geared to switch 1. The gearing may be eliminated by a modification, Fig. 2 (not shown), wherein each switch has (3n-1) contacts, e.g. n=4, and the 1st, 4th, 7th &c. the 2nd, 5th, 8th &c. and the 3rd, 6th, 9th &c. of each switch are linked together, the three links of each switch being connected to the interconnecting lines in the same manner as the contacts of switches 1, 9, 10 described above. The position of the missing 30th contact is occupied by a stop which prevents the wiper from moving clockwise from the initial position or from moving anti-clockwise from the final position. The relays 11 and 12 may be replaced by the two windings of a split field motor or of an exciter forming part of a reversible Ward-Leonard system and each rotary switch may be replaced by a switch with linearly disposed contacts or by a plurality of cam-operated switches. If required a number of trailer units may be connected in parallel with the lines 6, 7, 8.

Title: Filter for fluids
IPC: B01D35/12
Filed: 1965-06-24
Abstract: 1,075,775. Fluid-pressure servomotor systems. J.T. RYMER. June 24, 1966 [June 24, 1965], No. 26724/65. Heading G3P. [Also in Division B1] A control valve 18 monitors the pressure drop across a set of filter units 14, connected in parallel, and responds to filter clogging by moving the piston 27 of their common distributor valve 13, which causes the inlet of each unit in turn to be connected to drain so that the unit is backwashed by filtered liquid while forward flow continues on other units. When each unit has been backwashed the valve 18 and piston 27 return to their original positions. During normal filtering Fig. 1 (not shown) pump 10 delivers liquid to inlet 29 of valve 13 and slot 28 in piston 27, and internal bores and slots 43a Figs.12..15 (not shown), deliver it to ports 30 leading to various units 14. Piston 19 of valve 18 is held in its left hand position by connections 20, 21 to upstream and downstream of filters and by spring 22. Once increased pressure moves piston 19 off its seat 23 it contacts a greater area so that piston 19 moves rightwards abruptly, and the lower and upper ends of valve 13 are thereby connected to upstream and downstream pressures by respective aligned passages 34, 35, 20 and 61, 32, 36 in valve 18. Piston 27 begins to rise, and each port 30 in turn communicates with slots 39 in piston 27 which connect by a slot (40) with drain line 42. Forward flow is restored to each newly backwashed unit 14 through lower slots 43. At the top of its movement a slot 46 in piston 27 aligns with a port 47 and delivers upstream pressure by line 48 to the right hand side of a piston 50 in valve 18, piston 50 moving to restore piston 19 to its left hand position. This restores upstream and downstream pressure to above and below piston 27 which is thereby restored to its initial position, backwashing each unit 14 a second time in its downward movement. The lower end of valve 13 may have a further piston 56 with a circumferential groove 55 and a spring 57. During each pressuring of space 33 below piston 27, piston 56 is moved downwards and a quantity of sludge, trapped in groove 55 when it was aligned with sludge drain ports 54 leading to filter units 14, is discharged through line 59 to container 60. Alternatively, inlet and outlet connections 15, 16 may enter the lower ends of units 14, in which case solids are removed with backwashing liquid to sump 11. In another embodiment Figs. 3.. 11 (not shown) filter units 14 comprising elements (81) enclosed in individual casings (79), are grouped round distribution valve 31 inside a common housing (82) with control valve 18 on the top, and various connections are formed by drilled holes and open channels adapted to be closed by aligned plates.

Abstract: 1470545 Branching filters EMERSON ELECTRIC CO 17 June 1974 [29 June 1973] 26724/74 Heading H1W [Also in Division H4] A duplexer/diplexer comprises at least two TR channels one of which is coupled to a common waveguide by branch guides which act as a high-pass filter for the signals in that channel and a cut-off filter for the signals in the other channel. In one four-channel arrangement, two groups of two channels utilize first and second frequency bands, the two channels within each group being mutually orthogonally polarized. Thus, the signals in the two channels sharing the higher of the two frequency bands are fed respectively by waveguides 90, 95, Fig. 6, to respective balanced couplers feeding orthogonal signals to common waveguide 20. One of these couplers comprises T-junction 97a, 92a, 92b connected by tapers 120 to 0-db couplers 14, 15 and the other (not completely shown) comprises a similar T-junction connected to 0-db couplers 25, 27. Each coupler comprises a series of branch waveguides 110 extending between series of transverse slots 112, 114 respectively in the feed waveguides and the common waveguides. The branch waveguides 110 are dimensioned beyond cut-off for signals in the pair of channels utilizing the lower frequency band. The latter are fed by respective waveguides 115, 116 to an orthomode junction 40 at the end of the common waveguide 20. The portion of the common guide 20 associated with couplers 14, 15, 25, 27 is mounted between rotational joints so that the polarizations of the two frequency bands may be adjusted with respect to each other. In a modification, these rotational joints are dispensed with and the adjustment effected according to the scheme shown in Fig. 2. These, pairs of channels in respective frequency bands are fed to orthomode joints 65, 71 for transmission through rotationally-adjustable 180 degree plates 61, 60 which, in known fashion, may be used for adjustment of the polarization angle between the two frequency channels.
